General Description of the Trust and the Fund

The Trust currently consists of 9 investment series or portfolios. The Trust was organized as a Delaware statutory trust on February 19, 2020 and is authorized to have multiple series or portfolios. The Trust is an open-endmanagement investment company registered with the SEC under the 1940 Act. The offering of the Trust's shares is registered under the Securities Act of 1933, as amended (the "1933 Act"). This SAI relates solely to the Fund.

The Fund primarily seeks to provide high current income and secondarily seeks to provide long-term capital appreciation.

The Fund is managed by BlackRock Fund Advisors ("BFA," the "Investment Adviser" or the "Manager"), an indirect wholly-owned subsidiary of BlackRock, Inc.

The Fund offers and issues shares at its net asset value per share ("NAV") only in aggregations of a specified number of shares (each, a "Creation Unit"), generally in exchange for a specified amount of cash. Shares of the Fund are listed for trading on Cboe BZX ("Cboe" or the "Listing Exchange"), a national securities exchange. Shares of the Fund are traded in the secondary market and elsewhere at market prices that may be at, above or below the Fund's NAV. Shares are redeemable only in Creation Units, and, generally, in exchange for a specified amount of cash. Creation Units typically are a specified number of shares, generally 50,000 or multiples thereof.

The Trust reserves the right to permit or require that creations and redemptions of shares are effected fully in cash. See the Creation and Redemption of Creation Unitssection of this SAI. Transaction fees and other costs associated with creations or redemptions that include a cash portion may be higher than the transaction fees and other costs associated with in-kindcreations or redemptions. In all cases, conditions with respect to creations and redemptions of shares and fees will be limited in accordance with the requirements of SEC rules and regulations applicable to management investment companies offering redeemable securities.

Exchange Listing and Trading

A discussion of exchange listing and trading matters associated with an investment in the Fund is contained in the Shareholder Informationsection of the Fund's Prospectus. The discussion below supplements, and should be read in conjunction with, that section of the Prospectus.

Shares of the Fund are listed for trading, and trade throughout the day, on the Listing Exchange and in other secondary markets. There can be no assurance that the requirements of the Listing Exchange necessary to maintain the listing of shares of the Fund will continue to be met. The Listing Exchange may, but is not required to, remove the shares of the Fund from listing if, among other things: (i) the Fund is no longer eligible to operate in reliance on Rule 6c-11under the Investment Company Act, (ii) any of the other listing requirements are not continuously maintained; or (iii) any other event shall occur or condition shall exist that, in the opinion of the Listing Exchange, makes further dealings on the Listing Exchange inadvisable. The Listing Exchange will also remove shares of the Fund from listing and trading upon termination of the Fund.

As in the case of other publicly-traded securities, when you buy or sell shares of the Fund through a broker, you may incur a brokerage commission determined by that broker, as well as other charges.

The Trust reserves the right to adjust the share prices of the Fund in the future to maintain convenient trading ranges for investors. Any adjustments would be accomplished through stock splits or reverse stock splits, which would have no effect on the net assets of the Fund or an investor's equity interest in the Fund.

Investment Strategies and Risks

The Fund normally invests at least 80% of its assets in floating rate loans and investments that are the economic equivalent of floating rate loans, which effectively enables the Fund to achieve a floating rate of income. The Fund may also invest in other floating rate debt instruments and investments that are the economic equivalent of floating rate debt instruments. The Fund's investments may include, but are not limited to, any combination of the following: (i) senior secured floating rate loans or debt; (ii) second lien or other subordinated or unsecured floating rate loans or debt; and (iii) fixed-rate loans or debt with respect to which the Fund has entered into derivative instruments to effectively convert the fixed-rate interest payments into floating rate interest payments. The Fund may also purchase and sell, without limitation, participations or assignments in senior floating rate loans or second lien floating rate loans.

For purposes of the Fund's investments, the term debt instruments includes convertible or preferred securities.

The Fund may invest in investments of any credit quality without limitation, including investments rated below investment grade. The Fund anticipates that, under current market conditions, a substantial portion of its portfolio will consist of leveraged loans rated below investment grade and similar investments. These investments are expected to exhibit credit risks similar to high yield securities, which are commonly referred to as "junk bonds."

The Fund may invest up to 20% of its assets in fixed-rate loans and fixed income securities with respect to which the Fund has not entered into derivative instruments to effectively convert the fixed-rate interest payments into floating-rate interest payments. Such fixed-rate loans and fixed income securities include, but are not limited to, senior loans, second lien loans, corporate bonds, preferred securities, convertible securities, mezzanine investments, collateralized loan obligations, structured products and U.S. government debt securities.

The Fund's investments in any floating rate and fixed income instruments may be of any duration or maturity. The Fund may invest in loans or debt of foreign issuers, including issuers located in emerging markets, without limitation. The Fund may also invest up to 15% of its net assets in illiquid investments. The Fund intends to invest in certain high yield securities and exchange-traded funds ("ETFs") for liquidity purposes.

The Fund may also invest in companies whose financial condition is uncertain, where the borrower has defaulted in the payment of interest or principal or in the performance of its covenants or agreements, or that may be involved in bankruptcy proceedings, reorganizations or financial restructurings.

The Fund may invest up to 10% of its assets in common stocks or other equity securities. In addition, the Fund may acquire and hold such securities (or rights to acquire such securities) in unit offerings with fixed income securities, in connection with an amendment, waiver, conversion or exchange of

2

fixed income securities, in connection with the bankruptcy or workout of a distressed fixed income security, or upon the exercise of a right or warrant obtained on account of a fixed income security.

The Fund may buy or sell options or futures on a security or an index of securities, buy or sell options on futures or enter into credit default swaps and interest rate or foreign currency transactions, including swaps and forward contracts (collectively, commonly known as derivatives). The Fund may use derivatives for hedging purposes, but is not required to, as well as to increase the total return on its portfolio investments.

The Fund is classified as non-diversified under the Investment Company Act.

Asset-Backed Securities.Asset-backed securities are securities backed by home equity loans, installment sale contracts, credit card receivables or other assets. Asset-backed securities are "pass-through" securities, meaning that principal and interest payments - net of expenses - made by the borrower on the underlying assets (such as credit card receivables) are passed through to the Fund. The value of asset-backed securities, like that of traditional fixed-income securities, typically increases when interest rates fall and decreases when interest rates rise. However, asset-backed securities differ from traditional fixed-income securities because of their potential for prepayment. The price paid by the Fund for its asset-backed securities, the yield the Fund expects to receive from such securities and the average life of the securities are based on a number of factors, including the anticipated rate of prepayment of the underlying assets. In a period of declining interest rates, borrowers may prepay the underlying assets more quickly than anticipated, thereby reducing the yield to maturity and the average life of the asset-backed securities. Moreover, when the Fund reinvests the proceeds of a prepayment in these circumstances, it will likely receive a rate of interest that is lower than the rate on the security that was prepaid. To the extent that the Fund purchases asset-backed securities at a premium, prepayments may result in a loss to the extent of the premium paid. If the Fund buys such securities at a discount, both scheduled payments and unscheduled prepayments will increase current and total returns and unscheduled prepayments will also accelerate the recognition of income which, when distributed to shareholders, will be taxable as ordinary income. In a period of rising interest rates, prepayments of the underlying assets may occur at a slower than expected rate, creating maturity extension risk. This particular risk may effectively change a security that was considered short- or intermediate-term at the time of purchase into a longer term security. Since the value of longer-term securities generally fluctuates more widely in response to changes in interest rates than does the value of shorter-term securities, maturity extension risk could increase the volatility of the Fund. When interest rates decline, the value of an asset-backed security with prepayment features may not increase as much as that of other fixed-income securities, and, as noted above, changes in market rates of interest may accelerate or retard prepayments and thus affect maturities.

Asset-Based Securities.The Fund may invest in debt, preferred or convertible securities, the principal amount, redemption terms or conversion terms of which are related to the market price of some natural resource asset such as gold bullion. These securities are referred to as "asset-based securities." The Fund will purchase only asset-based securities that are rated, or are issued by issuers that have outstanding debt obligations rated, investment grade (for example, AAA, AA, A or BBB by S&P Global Ratings ("S&P") or Fitch Ratings ("Fitch"), or Baa by Moody's Investors Service, Inc. ("Moody's") or commercial paper rated A-1by S&P or Prime-1by Moody's) or by issuers that the Investment Adviser has determined to be of similar creditworthiness. Obligations ranked in the fourth highest rating category, while considered "investment grade," may have certain speculative characteristics and may be more likely to be downgraded than securities rated in the three highest rating categories. If an asset-based security is backed by a bank letter of credit or other similar facility, the Investment Adviser may take such backing into account in determining the creditworthiness of the issuer. While the market prices for an asset-based security and the related natural resource asset generally are expected to move in the same direction, there may not be perfect correlation in the two

3

price movements. Asset-based securities may not be secured by a security interest in or claim on the underlying natural resource asset. The asset-based securities in which the Fund may invest may bear interest or pay preferred dividends at below market (or even relatively nominal) rates. Certain asset-based securities may be payable at maturity in cash at the stated principal amount or, at the option of the holder, directly in a stated amount of the asset to which it is related. In such instance, because the Fund does not presently intend to invest directly in natural resource assets, the Fund would sell the asset-based security in the secondary market, to the extent one exists, prior to maturity if the value of the stated amount of the asset exceeds the stated principal amount and thereby realize the appreciation in the underlying asset.

Precious Metal-Related Securities.The Fund may invest in the equity and other securities of companies that explore for, extract, process or deal in precious metals (e.g., gold, silver and platinum), and in asset-based securities indexed to the value of such metals. Such securities may be purchased when they are believed to be attractively priced in relation to the value of a company's precious metal-related assets or when the values of precious metals are expected to benefit from inflationary pressure or other economic, political or financial uncertainty or instability. Based on historical experience, during periods of economic or financial instability the securities of companies involved in precious metals may be subject to extreme price fluctuations, reflecting the high volatility of precious metal prices during such periods. In addition, the instability of precious metal prices may result in volatile earnings of precious metal-related companies, which may, in turn, adversely affect the financial condition of such companies. The major producers of gold include the Republic of South Africa, Russia, Canada, the United States, Brazil and Australia. Sales of gold by Russia are largely unpredictable and often relate to political and economic considerations rather than to market forces. Economic, financial, social and political factors within South Africa may significantly affect South African gold production.

Bonds. A bond is an interest-bearing security issued by a U.S. or non-U.S.company, or U.S. governmental unit. The issuer of a bond has a contractual obligation to pay interest at a stated rate on specific dates and to repay principal (the bond's face value) periodically or on a specified maturity date. Bonds generally are used by issuers to borrow money from investors.

An issuer may have the right to redeem or "call" a bond before maturity, in which case the Fund may have to reinvest the proceeds at lower market rates. Similarly, a fund may have to reinvest interest income or payments received when bonds mature, sometimes at lower market rates. Most bonds bear interest income at a "coupon" rate that is fixed for the life of the bond. The value of a fixed-rate bond usually rises when market interest rates fall, and falls when market interest rates rise. Accordingly, a fixed-rate bond's yield (income as a percent of the bond's current value) may differ from its coupon rate as its value rises or falls. When an investor purchases a fixed-rate bond at a price that is greater than its face value, the investor is purchasing the bond at a premium. Conversely, when an investor purchases a fixed-rate bond at a price that is less than its face value, the investor is purchasing the bond at a discount. Fixed-rate bonds that are purchased at a discount pay less current income than securities with comparable yields that are purchased at face value, with the result that prices for such fixed-rate securities can be more volatile than prices for such securities that are purchased at face value. Other types of bonds bear interest at an interest rate that is adjusted periodically. Interest rates on "floating rate" or "variable rate" bonds may be higher or lower than current market rates for fixed-rate bonds of comparable quality with similar final maturities. Because of their adjustable interest rates, the value of "floating rate" or "variable rate" bonds fluctuates much less in response to market interest rate movements than the value of fixed-rate bonds, but their value may decline if their interest rates do not rise as much, or as quickly, as interest rates in general. The Fund may treat some of these bonds as having a shorter maturity for purposes of calculating the weighted average maturity of its investment portfolio. Generally, prices of higher quality issues tend to fluctuate less with changes in market interest rates than prices of lower quality issues and prices of longer maturity issues tend to fluctuate more than prices of shorter maturity issues. Bonds may be senior or subordinated obligations. Senior

4

obligations generally have the first claim on an issuer's earnings and assets and, in the event of liquidation, are paid before subordinated obligations. Bonds may be unsecured (backed only by the issuer's general creditworthiness) or secured (backed by specified collateral).

Borrowing. The Fund may borrow for temporary or emergency purposes, including to meet payments due from redemptions or to facilitate the settlement of securities or other transactions.

The Fund may also borrow in order to make investments, to the extent disclosed in the Prospectus. The purchase of securities while borrowings are outstanding may have the effect of leveraging the Fund. The incurrence of leverage increases the Fund's exposure to risk, and borrowed funds are subject to interest costs that will reduce net income. Purchasing securities while borrowings are outstanding creates special risks, such as the potential for greater volatility in the NAV of Fund shares and in the yield on the Fund's portfolio. In addition, the interest expenses from borrowings may exceed the income generated by the Fund's portfolio and, therefore, the amount available (if any) for distribution to shareholders as dividends may be reduced. BFA may determine to maintain outstanding borrowings if it expects that the benefits to the Fund's shareholders will outweigh the current reduced return.

Certain types of borrowings by the Fund must be made from a bank or may result in the Fund being subject to covenants in credit agreements relating to asset coverage, portfolio composition requirements and other matters. It is not anticipated that observance of such covenants would impede BFA's management of the Fund's portfolio in accordance with the Fund's investment objective(s) and policies. However, a breach of any such covenants not cured within the specified cure period may result in acceleration of outstanding indebtedness and require the Fund to dispose of portfolio investments at a time when it may be disadvantageous to do so.

Brady Bonds. The Fund may invest in Brady bonds. Brady bonds are securities created through the exchange of existing commercial bank loans to public and private entities in certain emerging markets for new bonds in connection with debt restructurings. Brady bonds have been issued since 1989. In light of the history of defaults of countries issuing Brady bonds on their commercial bank loans, investments in Brady bonds may be viewed as speculative and subject to the same risks as emerging market securities. Brady bonds may be fully or partially collateralized or uncollateralized, are issued in various currencies (but primarily the U.S. dollar) and are actively traded in over-the-counter("OTC") secondary markets. Incomplete collateralization of interest or principal payment obligations results in increased credit risk. U.S. dollar-denominated collateralized Brady bonds, which may be either fixed-rate or floating rate bonds, are generally collateralized by U.S. Treasury securities.

Collateralized Debt Obligations.The Fund may invest in collateralized debt obligations ("CDOs"), which include collateralized bond obligations ("CBOs"), collateralized loan obligations ("CLOs") and other similarly structured securities. CDOs are types of asset-backed securities. A CBO is ordinarily issued by a trust or other special purpose entity ("SPE") and is typically backed by a diversified pool of fixed-income securities (which may include high risk, below investment grade securities) held by such issuer. A CLO is ordinarily issued by a trust or other SPE and is typically collateralized by a pool of loans, which may include, among others, domestic and non-U.S.senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans, held by such issuer. Investments in a CLO organized outside of the United States may not be deemed to be foreign securities if the CLO is collateralized by a pool of loans, a substantial portion of which are U.S. loans. Although certain CDOs may benefit from credit enhancement in the form of a senior-subordinate structure, over-collateralization or bond insurance, such enhancement may not always be present, and may fail to protect the Fund against the risk of loss on default of the collateral. Certain CDO issuers may use derivatives contracts to create "synthetic"

5

exposure to assets rather than holding such assets directly, which entails the risks of derivative instruments described elsewhere in this SAI. CDOs may charge management fees and administrative expenses, which are in addition to those of the Fund.

For both CBOs and CLOs, the cash flows from the SPE are split into two or more portions, called tranches, varying in risk and yield. The riskiest portion is the "equity" tranche, which bears the first loss from defaults from the bonds or loans in the SPE and serves to protect the other, more senior tranches from default (though such protection is not complete). Since it is partially protected from defaults, a senior tranche from a CBO or CLO typically has higher ratings and lower yields than its underlying securities, and may be rated investment grade. Despite the protection from the equity tranche, CBO or CLO tranches can experience substantial losses due to actual defaults, downgrades of the underlying collateral by rating agencies, forced liquidation of the collateral pool due to a failure of coverage tests, increased sensitivity to defaults due to collateral default and disappearance of protecting tranches, market anticipation of defaults as well as investor aversion to CBO or CLO securities as a class. Interest on certain tranches of a CDO may be paid in kind or deferred and capitalized (paid in the form of obligations of the same type rather than cash), which involves continued exposure to default risk with respect to such payments.

The risks of an investment in a CDO depend largely on the type of the collateral securities and the class of the CDO in which the Fund invests. Normally, CBOs, CLOs and other CDOs are privately offered and sold, and thus are not registered under the securities laws. However, an active dealer market may exist for CDOs, allowing a CDO to qualify for Rule 144A transactions. In addition to the normal risks associated with fixed-income securities and asset-backed securities generally discussed elsewhere in this SAI, CDOs carry additional risks including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the risk that the collateral may default or decline in value or be downgraded, if rated by a nationally recognized statistical rating organization ("NRSRO"); (iii) the Fund may invest in tranches of CDOs that are subordinate to other tranches; (iv) the structure and complexity of the transaction and the legal documents could lead to disputes among investors regarding the characterization of proceeds; (v) the investment return achieved by the Fund could be significantly different than those predicted by financial models; (vi) the lack of a readily available secondary market for CDOs; (vii) the risk of forced "fire sale" liquidation due to technical defaults such as coverage test failures; and (viii) the CDO's manager may perform poorly.

Commercial Paper.The Fund may purchase commercial paper. Commercial paper purchasable by the Fund includes "Section 4(a)(2) paper," a term that includes debt obligations issued in reliance on the "private placement" exemption from registration afforded by Section 4(a)(2) of the Securities Act. Section 4(a)(2) paper is restricted as to disposition under the Federal securities laws, and is frequently sold (and resold) to institutional investors such as the Fund through or with the assistance of investment dealers who make a market in the Section 4(a)(2) paper, thereby providing liquidity. Certain transactions in Section 4(a)(2) paper may qualify for the registration exemption provided in Rule 144A under the Securities Act. The Fund can purchase commercial paper rated (at the time of purchase) "A-1"by S&P or "Prime-1"by Moody's or when deemed advisable by the Investment Adviser, "high quality" issues rated "A-2","Prime-2"or "F-2"by S&P, Moody's or Fitch, respectively.

Commodity-Linked Derivative Instruments and Hybrid Instruments.The Fund may seek to gain exposure to the commodities markets primarily through investments in hybrid instruments. Hybrid instruments are either equity or debt derivative securities with one or more commodity-dependent components that have payment features similar to a commodity futures contract, a commodity option contract, or a combination of both. Therefore, these instruments are "commodity-linked." They are considered "hybrid" instruments because they have both commodity-like and security-like

6

characteristics. Hybrid instruments are derivative instruments because at least part of their value is derived from the value of an underlying commodity, futures contract, index or other readily measurable economic variable.

The prices of commodity-linked derivative instruments may move in different directions than investments in traditional equity and debt securities when the value of those traditional securities is declining due to adverse economic conditions. As an example, during periods of rising inflation, debt securities have historically tended to decline in value due to the general increase in prevailing interest rates. Conversely, during those same periods of rising inflation, the prices of certain commodities, such as oil and metals, have historically tended to increase. Of course, there cannot be any guarantee that these investments will perform in that manner in the future, and at certain times the price movements of commodity-linked instruments have been parallel to those of debt and equity securities. Commodities have historically tended to increase and decrease in value during different parts of the business cycle than financial assets. Nevertheless, at various times, commodities prices may move in tandem with the prices of financial assets and thus may not provide overall portfolio diversification benefits. Under favorable economic conditions, the Fund's investments may be expected to under-perform an investment in traditional securities. Over the long term, the returns on the Fund's investments are expected to exhibit low or negative correlation with stocks and bonds.

Counterparty Risk. A significant risk of hybrid instruments is counterparty risk. Unlike exchange-traded futures and options, which are standard contracts, hybrid instruments are customized securities, tailor-made by a specific issuer. With a listed futures or options contract, an investor's counterparty is the exchange clearinghouse. Exchange clearinghouses are capitalized by the exchange members and typically have high investment grade ratings (e.g., ratings of AAA or AA by S&P). Therefore, the risk is small that an exchange clearinghouse might be unable to meet its obligations at maturity. However, with a hybrid instrument, the Fund will take on the counterparty credit risk of the issuer. That is, at maturity of the hybrid instrument, there is a risk that the issuer may be unable to perform its obligations under the structured note.

Convertible Securities.A convertible security is a bond, debenture, note, preferred stock or other security that may be converted into or exchanged for a prescribed amount of common stock or other equity security of the same or a different issuer within a particular period of time at a specified price or formula. A convertible security entitles the holder to receive interest paid or accrued on debt or the dividend paid on preferred stock until the convertible security matures or is redeemed, converted or exchanged. Before conversion, convertible securities have characteristics similar to nonconvertible income securities in that they ordinarily provide a stable stream of income with generally higher yields than those of common stocks of the same or similar issuers, but lower yields than comparable nonconvertible securities. The value of a convertible security is influenced by changes in interest rates, with investment value declining as interest rates increase and increasing as interest rates decline. The credit standing of the issuer and other factors also may have an effect on the convertible security's investment value. Convertible securities rank senior to common stock in a corporation's capital structure but are usually subordinated to comparable nonconvertible securities. Convertible securities may be subject to redemption at the option of the issuer at a price established in the convertible security's governing instrument.

The characteristics of convertible securities make them potentially attractive investments for an investment company seeking a high total return from capital appreciation and investment income. These characteristics include the potential for capital appreciation as the value of the underlying common stock increases, the relatively high yield received from dividend or interest payments as compared to common stock dividends and decreased risks of decline in value relative to the underlying common stock due to their fixed-income nature. As a result of the conversion feature, however, the interest rate or dividend preference on a convertible security is generally less than would be the case if the securities were issued in nonconvertible form.

7

In analyzing convertible securities, the Investment Adviser will consider both the yield on the convertible security relative to its credit quality and the potential capital appreciation that is offered by the underlying common stock, among other things.

Convertible securities are issued and traded in a number of securities markets. Even in cases where a substantial portion of the convertible securities held by the Fund are denominated in U.S. dollars, the underlying equity securities may be quoted in the currency of the country where the issuer is domiciled. As a result, fluctuations in the exchange rate between the currency in which the debt security is denominated and the currency in which the share price is quoted will affect the value of the convertible security. With respect to convertible securities denominated in a currency different from that of the underlying equity securities, the conversion price may be based on a fixed exchange rate established at the time the security is issued, which may increase the effects of currency risk. As described below, the Fund is authorized to enter into foreign currency hedging transactions in which it may seek to reduce the effect of exchange rate fluctuations.

Apart from currency considerations, the value of convertible securities is influenced by both the yield on nonconvertible securities of comparable issuers and by the value of the underlying common stock. The value of a convertible security viewed without regard to its conversion feature (i.e., strictly on the basis of its yield) is sometimes referred to as its "investment value." To the extent interest rates change, the investment value of the convertible security typically will fluctuate. At the same time, however, the value of the convertible security will be influenced by its "conversion value," which is the market value of the underlying common stock that would be obtained if the convertible security were converted. Conversion value fluctuates directly with the price of the underlying common stock. If the conversion value of a convertible security is substantially below its investment value, the price of the convertible security is governed principally by its investment value. To the extent the conversion value of a convertible security increases to a point that approximates or exceeds its investment value, the price of the convertible security will be influenced principally by its conversion value. A convertible security will sell at a premium over the conversion value to the extent investors place value on the right to acquire the underlying common stock while holding a fixed-income security. The yield and conversion premium of convertible securities issued in Japan and the Euromarket are frequently determined at levels that cause the conversion value to affect their market value more than the securities' investment value.

Holders of convertible securities generally have a claim on the assets of the issuer prior to the common stockholders but may be subordinated to other debt securities of the same issuer. A convertible security may be subject to redemption at the option of the issuer at a price established in a charter provision, indenture or other governing instrument pursuant to which the convertible security was issued. If a convertible security held by the Fund is called for redemption, the Fund will be required to redeem the security, convert it into the underlying common stock or sell it to a third party. Certain convertible debt securities may provide a put option to the holder, which entitles the holder to cause the security to be redeemed by the issuer at a premium over the stated principal amount of the debt security under certain circumstances.

The Fund may also invest in synthetic convertible securities. Synthetic convertible securities may include either Cash-Settled Convertibles or Manufactured Convertibles. "Cash-Settled Convertibles" are instruments that are created by the issuer and have the economic characteristics of traditional convertible securities but may not actually permit conversion into the underlying equity securities in all circumstances. As an example, a private company may issue a Cash-Settled Convertible that is convertible into common stock only if the company successfully completes a public offering of its common stock prior to maturity and otherwise pays a cash amount to reflect any equity appreciation. "Manufactured Convertibles" are created by the Investment Adviser or another party by combining

8

separate securities that possess one of the two principal characteristics of a convertible security, i.e., fixed-income ("fixed-income component") or a right to acquire equity securities ("convertibility component"). The fixed-income component is achieved by investing in nonconvertible fixed-income securities, such as nonconvertible bonds, preferred stocks and money market instruments. The convertibility component is achieved by investing in call options, warrants, or other securities with equity conversion features ("equity features") granting the holder the right to purchase a specified quantity of the underlying stocks within a specified period of time at a specified price or, in the case of a stock index option, the right to receive a cash payment based on the value of the underlying stock index.

A Manufactured Convertible differs from traditional convertible securities in several respects. Unlike a traditional convertible security, which is a single security that has a unitary market value, a Manufactured Convertible is comprised of two or more separate securities, each with its own market value. Therefore, the total "market value" of such a Manufactured Convertible is the sum of the values of its fixed-income component and its convertibility component.

More flexibility is possible in the creation of a Manufactured Convertible than in the purchase of a traditional convertible security. Because many corporations have not issued convertible securities, the Investment Adviser may combine a fixed-income instrument and an equity feature with respect to the stock of the issuer of the fixed-income instrument to create a synthetic convertible security otherwise unavailable in the market. The Investment Adviser may also combine a fixed-income instrument of an issuer with an equity feature with respect to the stock of a different issuer when the Investment Adviser believes such a Manufactured Convertible would better promote the Fund's objectives than alternative investments. For example, the Investment Adviser may combine an equity feature with respect to an issuer's stock with a fixed-income security of a different issuer in the same industry to diversify the Fund's credit exposure, or with a U.S. Treasury instrument to create a Manufactured Convertible with a higher credit profile than a traditional convertible security issued by that issuer. A Manufactured Convertible also is a more flexible investment in that its two components may be purchased separately and, upon purchasing the separate securities, "combined" to create a Manufactured Convertible. For example, the Fund may purchase a warrant for eventual inclusion in a Manufactured Convertible while postponing the purchase of a suitable bond to pair with the warrant pending development of more favorable market conditions.

The value of a Manufactured Convertible may respond to certain market fluctuations differently from a traditional convertible security with similar characteristics. For example, in the event the Fund created a Manufactured Convertible by combining a short-term U.S. Treasury instrument and a call option on a stock, the Manufactured Convertible would be expected to outperform a traditional convertible of similar maturity that is convertible into that stock during periods when Treasury instruments outperform corporate fixed-income securities and underperform during periods when corporate fixed-income securities outperform Treasury instruments.

Corporate Bonds. The Fund may invest in investment-grade and/or high yield corporate bonds. High yield corporate bonds may be deemed speculative and more volatile than higher rated securities of similar maturity. The investment return of corporate bonds reflects interest earned on the security and changes in the market value of the security. The market value of a corporate bond may be affected by changes in the market rate of interest, the credit rating of the issuer, the corporation's performance and perceptions of the issuer in the marketplace. There is a risk that the issuers of the securities may not be able to meet their obligations on interest or principal payments at the time called for by an instrument.

Corporate Loans.The Fund may invest in corporate loans. Corporate loans are generally non-investmentgrade floating rate instruments. Usually, they are freely callable at the issuer's option.

The Fund may invest in fixed and floating rate loans ("Loans") arranged through private negotiations between a corporate borrower or a foreign sovereign entity and one or more financial institutions or institutional investors ("Lenders"). The Fund may invest in such Loans in the form of participations in Loans ("Participations") and assignments of all or a portion of Loans from third parties ("Assignments"). The Fund considers these investments to be investments in debt securities for purposes of its investment policies. Participations typically will result in the Fund having a contractual relationship only with the Lender, not with the borrower. The Fund will have the right to receive payments of principal, interest and any fees to which it is entitled only from the Lender selling the Participation and only upon receipt by the Lender of the payments from the borrower. In connection with purchasing Participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the Loans, nor any rights of set-offagainst the borrower, and the Fund may not benefit directly from any collateral supporting the Loan in which it has purchased the Participation. As a result, the Fund will assume the credit risk of both the borrower and the Lender that is selling the Participation. In the event of the insolvency of the Lender selling the Participation, the Fund may be treated as a general creditor of the Lender and may not benefit from any set-offbetween the Lender and the borrower. The Fund will acquire Participations only if the Lender interpositioned between the Fund and the borrower is determined by the Fund's manager to be creditworthy. When the Fund purchases Assignments from Lenders, the Fund will acquire direct rights against the borrower on the Loan, and will not have exposure to a counterparty's credit risk. The Fund may enter into Participations and Assignments on a forward commitment or "when-issued" basis, whereby the Fund would agree to purchase a Participation or Assignment at set terms in the future. For more information on forward commitments and when-issued securities, see "When-Issued Securities, Delayed Delivery Securities and Forward Commitments" below.

The Fund may have difficulty disposing of Assignments and Participations. In certain cases, the market for such instruments may lack sufficient liquidity, and therefore the Fund anticipates that in such cases such instruments could be sold only to a limited number of institutional investors. The lack of a sufficiently liquid secondary market may have an adverse impact on the value of such instruments and on the Fund's ability to dispose of particular Assignments or Participations in response to a specific economic event, such as deterioration in the creditworthiness of the borrower.

Leading financial institutions often act as agent for a broader group of Lenders, generally referred to as a syndicate. The syndicate's agent arranges the loans, holds collateral and accepts payments of principal and interest. If the agent develops financial problems, the Fund may not recover its investment or recovery may be delayed.

The Loans in which the Fund may invest are subject to the risk of loss of principal and income. Although borrowers frequently provide collateral to secure repayment of these obligations they do not always do so. If they do provide collateral, the value of the collateral may not completely cover the borrower's obligations at the time of a default. If a borrower files for protection from its creditors under the U.S. bankruptcy laws, these laws may limit the Fund's rights to its collateral. In addition, the value of collateral may erode during a bankruptcy case. In the event of a bankruptcy, the holder of a Loan may not recover its principal, may experience a long delay in recovering its investment and may not receive interest during the delay.

Transactions in corporate loans may settle on a delayed basis. As a result, the proceeds from the sale of corporate loans may not be readily available to make additional investments or to meet the Fund's redemption obligations. To the extent the extended settlement process gives rise to short-term liquidity needs, the Fund may hold additional cash, sell investments or temporarily borrow from banks and other lenders.

10

In certain circumstances, Loans may not be deemed to be securities under certain federal securities laws. Therefore, in the event of fraud or misrepresentation by a borrower or an arranger, Lenders and purchasers of interests in Loans, such as the Fund, may not have the protection of the anti-fraud provisions of the federal securities laws as would otherwise be available for bonds or stocks. Instead, in such cases, parties generally would rely on the contractual provisions in the Loan agreement itself and common-lawfraud protections under applicable state law.

Credit Linked Securities. Among the income producing securities in which the Fund may invest are credit linked securities, which are issued by a limited purpose trust or other vehicle that, in turn, invests in a derivative instrument or basket of derivative instruments, such as credit default swaps, interest rate swaps and other securities, in order to provide exposure to certain fixed-income markets. For instance, the Fund may invest in credit linked securities as a cash management tool in order to gain exposure to a certain market and/or to remain fully invested when more traditional income producing securities are not available.

Like an investment in a bond, investments in these credit linked securities represent the right to receive periodic income payments (in the form of distributions) and payment of principal at the end of the term of the security.

However, these payments are conditioned on the issuer's receipt of payments from, and the issuer's potential obligations to, the counterparties to the derivative instruments and other securities in which the issuer invests. For instance, the issuer may sell one or more credit default swaps, under which the issuer would receive a stream of payments over the term of the swap agreements provided that no event of default has occurred with respect to the referenced debt obligation upon which the swap is based. If a default occurs, the stream of payments may stop and the issuer would be obligated to pay the counterparty the par (or other agreed upon value) of the referenced debt obligation. This, in turn, would reduce the amount of income and principal that the Fund would receive. The Fund's investments in these instruments are indirectly subject to the risks associated with derivative instruments, including, among other risks, credit risk, default or similar event risk, counterparty risk, interest rate risk, leverage risk and management risk. It is also expected that the securities will be exempt from registration under the 1933 Act. Accordingly, there may be no established trading market for the securities and they may constitute illiquid investments. Some transactions may give rise to a form of economic leverage. These transactions may include, among other things, derivatives, and may expose the Fund to greater risk and increase its costs. Increases and decreases in the value of the Fund's portfolio will be magnified when the Fund uses leverage.

Currency Transactions.A currency forward contract is an OTC obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days greater than two days from the date on which the contract is agreed upon by the parties, at a price set at the time of the contract. A non-deliverablecurrency forward is an OTC currency forward settled in a specified currency, on a specified date, based on the difference between the agreed-upon exchange rate and the market exchange rate. A currency futures contract is a contract that trades on an organized futures exchange involving an obligation to deliver or acquire a specified amount of a specific currency, at a specified price and at a specified future time. Currency futures contracts may be settled on a net cash payment basis rather than by the sale and delivery of the underlying currency. The Fund may also enter into physically-settled non-U.S.currency forwards, and non-U.S.currency futures transactions and spot currency transactions to facilitate local securities settlements or to protect against currency exposure in connection with its distributions to shareholders.

Foreign exchange transactions may involve a significant degree of risk and the markets in which foreign exchange transactions are effected may be highly volatile, highly specialized and highly technical. Significant changes, including changes in liquidity and prices, can occur in such markets

11

within very short periods of time, often within minutes. Foreign exchange trading risks include, but are not limited to, exchange rate risk, counterparty risk, maturity gap, interest rate risk, and potential interference by foreign governments through regulation of local exchange markets, foreign investment or particular transactions in non-U.S.currency. The Fund could experience losses if the value of its currency forwards and other currency transactions positions were poorly correlated with its other investments or with its other currency hedges, if applicable, or if it could not close out its positions because of an illiquid market or otherwise. In addition, the Fund could incur transaction costs, including trading commissions, in connection with non-U.S.currency transactions.

Depositary Receipts (ADRs, EDRs and GDRs). The Fund may invest in the securities of foreign issuers in the form of Depositary Receipts or other securities convertible into securities of foreign issuers. Depositary Receipts may not necessarily be denominated in the same currency as the underlying securities into which they may be converted. The Fund may invest in both sponsored and unsponsored American Depositary Receipts ("ADRs"), European Depositary Receipts ("EDRs"), Global Depositary Receipts ("GDRs") and other similar global instruments. ADRs typically are issued by an American bank or trust company and evidence ownership of underlying securities issued by a foreign corporation. EDRs, which are sometimes referred to as Continental Depositary Receipts, are receipts issued in Europe, typically by foreign banks and trust companies, that evidence ownership of either foreign or domestic underlying securities. GDRs are depositary receipts structured like global debt issues to facilitate trading on an international basis. In addition to investment risks associated with the underlying issuer, Depositary Receipts expose the Fund to additional risks associated with the non-uniformterms that apply to Depositary Receipt programs, credit exposure to the depository bank and to the sponsors and other parties with whom the depository bank establishes the programs, currency risk and the risk of an illiquid market for Depositary Receipts. Unsponsored ADR, EDR and GDR programs are organized independently and without the cooperation of the issuer of the underlying securities. Unsponsored programs generally expose investors to greater risks than sponsored programs and do not provide holders with many of the shareholder benefits that come from investing in a sponsored Depositary Receipt. Available information concerning the issuer may not be as current as for sponsored ADRs, EDRs and GDRs, and the prices of unsponsored ADRs, EDRs and GDRs may be more volatile than if such instruments were sponsored by the issuer. Depositary Receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted. Investments in ADRs, EDRs and GDRs present additional investment considerations as described under "Foreign Investment Risks."

Derivatives. The Fund may use instruments referred to as derivatives. Derivatives are financial instruments the value of which is derived from another security, a commodity (such as gold or oil), a currency or an index (a measure of value or rates, such as the S&P 500 Index or the prime lending rate). Derivatives allow the Fund to increase or decrease the level of risk to which the Fund is exposed more quickly and efficiently than transactions in other types of instruments. The Fund may use derivatives for hedging purposes. The Fund may also use derivatives for speculative purposes to seek to enhance returns. The use of a derivative is speculative if the Fund is primarily seeking to achieve gains, rather than to offset the risk of other positions. When the Fund invests in a derivative for speculative purposes, the Fund will be fully exposed to the risks of loss of that derivative, which may sometimes be greater than the derivative's cost. Unless otherwise permitted, the Fund may not use any derivatives to gain exposure to an asset or class of assets that it would be prohibited by its investment restrictions from purchasing directly.

Distressed Securities. The Fund may invest in securities, including loans purchased in the secondary market, that are the subject of bankruptcy proceedings or otherwise in default or in risk of being in default as to the repayment of principal and/or interest at the time of acquisition by the Fund or that are rated in the lower rating categories by one or more nationally recognized statistical rating organizations

12

(for example, Ca or lower by Moody's and CC or lower by S&P or Fitch) or, if unrated, are in the judgment of the Investment Adviser of equivalent quality ("Distressed Securities"). Investment in Distressed Securities is speculative and involves significant risks.

The Fund will generally make such investments only when the Investment Adviser believes it is reasonably likely that the issuer of the Distressed Securities will make an exchange offer or will be the subject of a plan of reorganization pursuant to which the Fund will receive new securities in return for the Distressed Securities. However, there can be no assurance that such an exchange offer will be made or that such a plan of reorganization will be adopted. In addition, a significant period of time may pass between the time at which the Fund makes its investment in Distressed Securities and the time that any such exchange offer or plan of reorganization is completed. During this period, it is unlikely that the Fund will receive any interest payments on the Distressed Securities, the Fund will be subject to significant uncertainty as to whether or not the exchange offer or plan of reorganization will be completed and the Fund may be required to bear certain extraordinary expenses to protect and recover its investment. Therefore, to the extent the Fund seeks capital appreciation through investment in distressed securities, the Fund's ability to achieve current income for its shareholders may be diminished. The Fund also will be subject to significant uncertainty as to when and in what manner and for what value the obligations evidenced by the distressed securities will eventually be satisfied (e.g., through a liquidation of the obligor's assets, an exchange offer or plan of reorganization involving the distressed securities or a payment of some amount in satisfaction of the obligation). Even if an exchange offer is made or plan of reorganization is adopted with respect to Distressed Securities held by the Fund, there can be no assurance that the securities or other assets received by the Fund in connection with such exchange offer or plan of reorganization will not have a lower value or income potential than may have been anticipated when the investment was made or no value. Moreover, any securities received by the Fund upon completion of an exchange offer or plan of reorganization may be restricted as to resale. Similarly, if the Fund participates in negotiations with respect to any exchange offer or plan of reorganization with respect to an issuer of Distressed Securities, the Fund may be restricted from disposing of such securities. To the extent that the Fund becomes involved in such proceedings, the Fund may have a more active participation in the affairs of the issuer than that assumed generally by an investor. The Fund, however, will not make investments for the purpose of exercising day-to-daymanagement of any issuer's affairs.

Equity Securities.The Fund may invest in equity securities, which include common stock and preferred stock (including convertible preferred stock); bonds, notes and debentures convertible into common or preferred stock; stock purchase warrants and rights; equity interests in trusts; general and limited partnerships and limited liability companies; and depositary receipts. Stock markets are volatile. The price of equity securities will fluctuate and can decline and reduce the value of a portfolio investing in equities. The price of equity securities fluctuates based on changes in a company's financial condition and overall market and economic conditions. The value of equity securities purchased by the Fund could decline if the financial condition of the companies the Fund invests in decline or if overall market and economic conditions deteriorate. They may also decline due to factors that affect a particular industry or industries, such as labor shortages or increase in production costs and competitive conditions within an industry. In addition, they may decline due to general market conditions that are not specifically related to a company or industry, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates or generally adverse investor sentiment.

From time to time certain of the Funds may invest in shares of companies through initial public offerings ("IPOs"). IPOs have the potential to produce, and have in fact produced, substantial gains for certain Funds. There is no assurance that any Fund will have continued access to profitable IPOs and therefore investors should not rely on these past gains as an indication of future performance. The investment performance of a Fund during periods when it is unable to invest significantly or at all in

13

IPOs may be lower than during periods when it is able to do so. In addition, as a Fund increases in size, the impact of IPOs on its performance will generally decrease. Securities issued in IPOs are subject to many of the same risks as investing in companies with smaller market capitalizations. Securities issued in IPOs have no trading history, and information about the companies may be available for very limited periods. In addition, the prices of securities sold in IPOs may be highly volatile or may decline shortly after the initial public offering.

The Fund may invest in companies that have relatively small market capitalizations. These organizations will normally have more limited product lines, markets and financial resources and will be dependent upon a more limited management group than larger capitalized companies. In addition, it is more difficult to get information on smaller companies, which tend to be less well known, have shorter operating histories, do not have significant ownership by large investors and are followed by relatively few securities analysts. The securities of smaller capitalized companies are often traded in the OTC markets and may have fewer market makers and wider price spreads. This may result in greater price movements and less ability to sell the Fund's investment than if the Fund held the securities of larger, more established companies.

For a discussion of the types of equity securities in which your Fund may invest and the risks associated with investing in such equity securities, see your Fund's prospectus.

Real Estate-Related Securities. Although the Fund may not invest directly in real estate, the Fund may invest in equity securities of issuers that are principally engaged in the real estate industry. Such investments are subject to certain risks associated with the ownership of real estate and with the real estate industry in general. These risks include, among others: possible declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage funds or other limitations on access to capital; overbuilding; risks associated with leverage; market illiquidity; extended vacancies of properties; increase in competition, property taxes, capital expenditures and operating expenses; changes in zoning laws or other governmental regulation; costs resulting from the clean-upof, and liability to third parties for damages resulting from, environmental problems; tenant bankruptcies or other credit problems; casualty or condemnation losses; uninsured damages from floods, earthquakes or other natural disasters; limitations on and variations in rents, including decreases in market rates for rents; investment in developments that are not completed or that are subject to delays in completion; and changes in interest rates. To the extent that assets underlying the Fund's investments are concentrated geographically, by property type or in certain other respects, the Fund may be subject to certain of the foregoing risks to a greater extent. Investments by the Fund in securities of companies providing mortgage servicing will be subject to the risks associated with refinancings and their impact on servicing rights.

In addition, if the Fund receives rental income or income from the disposition of real property acquired as a result of a default on securities the Fund owns, the receipt of such income may adversely affect the Fund's ability to retain its tax status as a regulated investment company because of certain income source requirements applicable to regulated investment companies under the Code.

Securities of Smaller or Emerging Growth Companies. Investment in smaller or emerging growth companies involves greater risk than is customarily associated with investments in more established companies. The securities of smaller or emerging growth companies may be subject to more abrupt or erratic market movements than larger, more established companies or the market average in general. These companies may have limited product lines, markets or financial resources, or they may be dependent on a limited management group.

While smaller or emerging growth company issuers may offer greater opportunities for capital appreciation than large cap issuers, investments in smaller or emerging growth companies may involve

14

greater risks and thus may be considered speculative. Fund management believes that properly selected companies of this type have the potential to increase their earnings or market valuation at a rate substantially in excess of the general growth of the economy. Full development of these companies and trends frequently takes time.

Small cap and emerging growth securities will often be traded only in the OTC market or on a regional securities exchange and may not be traded every day or in the volume typical of trading on a national securities exchange. As a result, the disposition by the Fund of portfolio securities to meet redemptions or otherwise may require the Fund to make many small sales over a lengthy period of time, or to sell these securities at a discount from market prices or during periods when, in Fund management's judgment, such disposition is not desirable.

The process of selection and continuous supervision by Fund management does not, of course, guarantee successful investment results; however, it does provide access to an asset class not available to the average individual due to the time and cost involved. Careful initial selection is particularly important in this area as many new enterprises have promise but lack certain of the fundamental factors necessary to prosper. Investing in small cap and emerging growth companies requires specialized research and analysis. In addition, many investors cannot invest sufficient assets in such companies to provide wide diversification.

Small companies are generally little known to most individual investors although some may be dominant in their respective industries. Fund management believes that relatively small companies will continue to have the opportunity to develop into significant business enterprises. The Fund may invest in securities of small issuers in the relatively early stages of business development that have a new technology, a unique or proprietary product or service, or a favorable market position. Such companies may not be counted upon to develop into major industrial companies, but Fund management believes that eventual recognition of their special value characteristics by the investment community can provide above-average long-term growth to the portfolio.

Equity securities of specific small cap issuers may present different opportunities for long-term capital appreciation during varying portions of economic or securities market cycles, as well as during varying stages of their business development. The market valuation of small cap issuers tends to fluctuate during economic or market cycles, presenting attractive investment opportunities at various points during these cycles. Smaller companies, due to the size and kinds of markets that they serve, may be less susceptible than large companies to intervention from the Federal government by means of price controls, regulations or litigation.

Exchange-Traded Notes ("ETNs"). The Fund may invest in ETNs. ETNs are generally notes representing debt of the issuer, usually a financial institution. ETNs combine both aspects of bonds and ETFs. An ETN's returns are based on the performance of one or more underlying assets, reference rates or indexes, minus fees and expenses. Similar to ETFs, ETNs are listed on an exchange and traded in the secondary market. However, unlike an ETF, an ETN can be held until the ETN's maturity, at which time the issuer will pay a return linked to the performance of the specific asset, index or rate ("reference instrument") to which the ETN is linked minus certain fees. Unlike regular bonds, ETNs do not make periodic interest payments, and principal is not protected.

The value of an ETN may be influenced by, among other things, time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying markets, changes in the applicable interest rates, the performance of the reference instrument, changes in the issuer's credit rating and economic, legal, political or geographic events that affect the reference instrument. An ETN that is tied to a reference instrument may not replicate the performance of the reference instrument. ETNs also incur certain expenses not incurred by their applicable reference instrument. Some ETNs that use

15

leverage may, at times, be illiquid and may be difficult to purchase or sell at a fair price. Levered ETNs are subject to the same risk as other instruments that use leverage in any form. While leverage allows for greater potential return, the potential for loss is also greater. Finally, additional losses may be incurred if the investment loses value because, in addition to the money lost on the investment, the loan still needs to be repaid.

Because the return on the ETN is dependent on the issuer's ability or willingness to meet its obligations, the value of the ETN may change due to a change in the issuer's credit rating, despite no change in the underlying reference instrument. The market value of ETN shares may differ from the value of the reference instrument. This difference in price may be due to the fact that the supply and demand in the market for ETN shares at any point in time is not always identical to the supply and demand in the market for the assets underlying the reference instrument that the ETN seeks to track.

There may be restrictions on the Fund's right to redeem its investment in an ETN, which are generally meant to be held until maturity. The Fund's decision to sell its ETN holdings may be limited by the availability of a secondary market. An investor in an ETN could lose some or all of the amount invested.

Floating and Variable Rate Securities. The Fund may invest in debt instruments that pay a variable coupon rate. Securities with floating or variable interest rates can be less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general. Conversely, floating rate securities will not generally increase in value if interest rates decline. The impact of interest rate changes on floating rate investments is typically mitigated by the periodic interest rate reset of the investments. Benchmark interest rates used for floating and variable rate securities, such as the London Interbank Offer Rate ("LIBOR"), may not accurately track market interest rates.

Funding Agreements. The Fund may invest in Guaranteed Investment Contracts and similar funding agreements. In connection with these investments, the Fund makes cash contributions to a deposit fund of an insurance company's general account. The insurance company then credits to the Fund on a monthly basis guaranteed interest, which is based on an index (such as LIBOR). The funding agreements provide that this guaranteed interest will not be less than a certain minimum rate. The purchase price paid for a funding agreement becomes part of the general assets of the insurance company, and the contract is paid from the general assets of the insurance company. Generally, funding agreements are not assignable or transferable without the permission of the issuing insurance companies, and an active secondary market in some funding agreements does not currently exist.

Futures, Options on Futures and Securities Options. Futures contracts, options on futures and securities options may be used by the Fund to facilitate trading or to reduce transaction costs. The Fund may enter into futures contracts and options on futures that are traded on a U.S. or non-U.S.futures exchange. The Fund will not use futures, options on futures or securities options for speculative purposes. The Fund intends to use futures and options on futures in accordance with Rule 4.5 of the Commodity Futures Trading Commission ("CFTC") promulgated under the Commodity Exchange Act ("CEA"). BFA, with respect to the Fund, has claimed an exclusion from the definition of the term "commodity pool operator" in accordance with Rule 4.5 so that BFA, with respect to the Fund, is not subject to registration or regulation as a commodity pool operator under the CEA. See the Regulation Regarding Derivatives section of this SAI for more information.

Futures contracts provide for the future sale by one party and purchase by another party of a specified amount of a specific instrument or index at a specified future time and at a specified price. Stock index contracts are based on investments that reflect the market value of common stock of the firms included in the applicable interests. The Fund may enter into futures contracts to purchase securities indexes

16

when BFA anticipates purchasing the underlying securities and believes prices will rise before the purchase will be made. Upon entering into a futures contract, the Fund will be required to deposit with the broker an amount of cash or cash equivalents known as "initial margin," which is similar to a performance bond or good faith deposit on the contract and is returned to the Fund upon termination of the futures contract if all contractual obligations have been satisfied. Subsequent payments, known as "variation margin," will be made to and from the broker daily as the price of the instrument or index underlying the futures contract fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as "marking-to-market."At any time prior to the expiration of a futures contract, the Fund may elect to close the position by taking an opposite position, which will operate to terminate the Fund's existing position in the contract. An option on a futures contract, as contrasted with a direct investment in such a contract, gives the purchaser the right, but no obligation, in return for the premium paid, to assume a position in the underlying futures contract at a specified exercise price at any time prior to the expiration date of the option. Upon exercise of an option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer's futures margin account that represents the amount by which the market price of the futures contract exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the futures contract. The potential for loss related to the purchase of an option on a futures contract is limited to the premium paid for the option plus transaction costs. Because the value of the option is fixed at the point of sale, there are no daily cash payments by the purchaser to reflect changes in the value of the underlying contract; however, the value of the option changes daily and that change would be reflected in the NAV of the Fund. The potential for loss related to writing call options is unlimited. The potential for loss related to writing put options is limited to the agreed-upon price per share, also known as the "strike price," less the premium received from writing the put. The Fund may purchase and write put and call options on futures contracts that are traded on an exchange as a hedge against changes in value of their portfolio securities or in anticipation of the purchase of securities, and may enter into closing transactions with respect to such options to terminate existing positions. There is no guarantee that such closing transactions can be effected.

A call option gives a holder the right to purchase a specific security at a specified price ("exercise price") within a specified period of time. A put option gives a holder the right to sell a specific security at an exercise price within a specified period of time. The initial purchaser of a call option pays the "writer" a premium, which is paid at the time of purchase and is retained by the writer whether or not such option is exercised. The Fund may purchase put options to hedge its portfolio against the risk of a decline in the market value of securities held and may purchase call options to hedge against an increase in the price of securities it is committed to purchase. The Fund may write put and call options along with a long position in options to increase its ability to hedge against a change in the market value of the securities it holds or is committed to purchase.

The Fund may purchase or sell securities options on a U.S. or non-U.S.securities exchange or in the OTC market through a transaction with a dealer. Options on a securities index are typically settled on a net basis based on the appreciation or depreciation of the index level over the strike price. Options on single name securities may be cash- or physically-settled, depending upon the market in which they are traded. Options may be structured so as to be exercisable only on certain dates or on a daily basis. Options may also be structured to have conditions to exercise (i.e., "Knock-inEvents") or conditions that trigger termination (i.e., "Knock-outEvents").

Guarantees. The Fund may purchase securities which contain guarantees issued by an entity separate from the issuer of the security. Generally, the guarantor of a security (often an affiliate of the issuer) will fulfill an issuer's payment obligations under a security if the issuer is unable to do so.

17

Hedging. Hedging is a strategy in which a derivative is used to offset particular risks associated with other Fund holdings. Losses on the other investment may be substantially reduced by gains on a derivative that reacts in an opposite manner to market movements. While hedging can reduce losses, it can also reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated by the Fund or if the cost of the derivative outweighs the benefit of the hedge. Establishment of hedges, if not tailored properly or timed in accordance with market changes, may not be effective in meeting the Fund's intended objectives. This is due to the fact that hedging also involves correlation risk, i.e., the risk that changes in the value of the derivative will not match those of the holdings being hedged as expected by the Fund, in which case any losses on the holdings being hedged may not be reduced or may be increased. Physically settled currency contracts are not subject to centralized clearing and trading requirements in the U.S. but may be in other jurisdictions. In the U.S., NDFs must be traded into foreign currency contracts on a regulated exchange or facility and cleared through a central counterparty (a "CCP"). The Fund may also be subject to position limits in respect to the contracts established by a regulatory authority or exchange. There are no limitations on daily price moves in such foreign currency forward contracts, and banks and dealers are not required to continue to make markets in such contracts. There have been periods during which certain banks or dealers have refused to quote prices for such foreign currency forward contracts or have quoted prices with an unusually wide spread between the price at which the bank or dealer is prepared to buy and that at which it is prepared to sell. Governmental imposition of credit controls might limit any such foreign currency forward contract trading. With respect to its trading of foreign currency forward contracts, if any, the Fund will be subject to the risk of bank or dealer failure and the inability of, or refusal by, a bank or dealer to perform with respect to such contracts or, in the case of cleared contracts, the refusal of a CCP to clear a contract that is subject to mandatory clearing. Any such default would deprive the Fund of any potential profit or force the each to cover its commitments for resale at the then market price and could result in a loss to the Fund. The cost to the Fund of engaging in foreign currency forward contracts varies with such factors as the currencies involved, the length of the contract period, whether the contract is cash settled and, thus, would be subject to posting and collection of margin in the U.S. and the market conditions then prevailing. The inability to close options and futures positions also could have an adverse impact on the Fund's ability to hedge effectively its portfolio. There is also a risk of loss by the Fund of margin deposits or collateral in the event of bankruptcy of a broker or other intermediary with whom the Fund has an open position in a currency forward or NDF, a swap, an option, a futures contract, a related option or another hedging instrument.

High Yield Securities. The Fund may invest in non-investmentgrade securities. Non-investmentgrade or "high yield" fixed-income or convertible securities are commonly known to investors as "junk bonds" or "high yield bonds." These are generally debt securities that are rated below investment grade by one or more of the major rating agencies or are unrated securities that BFA believes are of comparable quality. While generally providing greater income and opportunity for gain, noninvestment grade debt securities may be subject to greater risks than securities that have higher credit ratings, including a high risk of default, and their yields will fluctuate over time. High yield securities will generally be in the lower rating categories of recognized rating agencies (rated below Baa3 by Moody's or below BBB-by S&P Global Ratings or Fitch) or be unrated. The credit rating of a high yield security does not necessarily address its market value risk, and ratings may from time to time change, positively or negatively, to reflect developments regarding the issuer's financial condition. High yield securities are considered to be speculative with respect to the capacity of the issuer to timely repay principal and pay interest in accordance with the terms of the obligation and may have more credit risk than higher rated securities.

18

The major risks of high yield bond investments include the following:

19

Inflation-Protected Obligations. The Fund may invest in inflation-protected public obligations of the U.S. Treasury, commonly known as "TIPS," and comparable securities issued by governments of other countries are designed to provide inflation protection to investors. Inflation-protected obligations are income-generating instruments whose interest and principal payments are adjusted for inflation - a sustained increase in prices that erodes the purchasing power of money. The inflation adjustment, which is typically applied monthly to the principal of the bond, follows a designated inflation index, the consumer price index ("CPI"), and TIPS' principal payments are adjusted according to changes in the CPI. A fixed-coupon rate is applied to the inflation-adjusted principal so that as inflation rises, both the principal value and the interest payments increase. This can provide investors with a hedge against inflation, as it helps preserve the purchasing power of an investment. Because of this inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds. The Fund is also subject to the risk that inflation rates of certain countries may be significantly higher than the rates indicated by official reports. As a result, the value of the bonds held by the Fund may decline in value even if payments to investors track reported inflation. Such securities are also subject to the risk of default by the issuing country.

Indexed and Inverse Securities. The Fund may invest in securities that provide a potential return based on a particular index of value or interest rates. For example, the Fund may invest in securities that pay interest based on an index of interest rates. The principal amount payable upon maturity of certain securities also may be based on the value of the index. To the extent the Fund invests in these types of securities, the Fund's return on such securities will be subject to risk with respect to the value of the particular index: that is, if the value of the index falls, the value of the indexed securities owned by the Fund will fall. Interest and principal payable on certain securities may also be based on relative changes among particular indices. The Fund may also invest in so-called"inverse floating obligations" or "residual interest bonds" on which the interest rates vary inversely with a floating rate (which may be reset periodically by a Dutch auction, a remarketing agent, or by reference to a short-term tax-exemptinterest rate index). The Fund may purchase synthetically-created inverse floating rate bonds evidenced by custodial or trust receipts. Generally, income on inverse floating rate bonds will decrease when interest rates increase, and will increase when interest rates decrease. Such securities have the effect of providing a degree of investment leverage, since they may increase or decrease in value in response to changes, as an illustration, in market interest rates at a rate that is a multiple of the rate at which fixed-rate securities increase or decrease in response to such changes. As a result, the market values of such securities will generally be more volatile than the market values of fixed-rate securities. To seek to limit the volatility of these securities, the Fund may purchase inverse floating obligations that have shorter-term maturities or that contain limitations on the extent to which the interest rate may vary. Certain investments in such obligations may be illiquid. The Investment Adviser believes that

20

indexed and inverse floating obligations represent flexible portfolio management instruments for the Fund that allow the Fund to seek potential investment rewards, hedge other portfolio positions or vary the degree of investment leverage relatively efficiently under different market conditions. The Fund may invest in indexed and inverse securities for hedging purposes or to seek to increase returns. When used for hedging purposes, indexed and inverse securities involve correlation risk. Furthermore, where such a security includes a contingent liability, in the event of an adverse movement in the underlying index or interest rate, the Fund may be required to pay substantial additional margin to maintain the position.

The Fund may invest up to 10% of its total assets in leveraged inverse floating rate debt instruments ("inverse floaters"). Inverse floaters are securities the potential of which is inversely related to changes in interest rates. In general, the return on inverse floaters will decrease when short-term interest rates increase and increase when short-term rates decrease. Municipal tender option bonds, both taxable and tax-exempt, which may include inverse floating rate debt instruments, (including residual interests thereon) are excluded from this 10% limitation.

Lease Obligations. The Fund may hold participation certificates in a lease, an installment purchase contract, or a conditional sales contract ("lease obligations"). BFA will monitor the credit standing of each borrower and each entity providing credit support and/or a put option relating to lease obligations. In determining whether a lease obligation is liquid, BFA will consider, among other factors, the following: (i) whether the lease can be cancelled; (ii) the degree of assurance that assets represented by the lease could be sold; (iii) the strength of the lessee's general credit (e.g., its debt, administrative, economic and financial characteristics); (iv) in the case of a municipal lease, the likelihood that the municipality would discontinue appropriating funding for the leased property because the property is no longer deemed essential to the operations of the municipality (e.g., the potential for an "event of non-appropriation"); (v) legal recourse in the event of failure to appropriate; (vi) whether the security is backed by a credit enhancement such as insurance; and (vii) any limitations which are imposed on the lease obligor's ability to utilize substitute property or services other than those covered by the lease obligation.

Lending Portfolio Securities. The Fund may lend portfolio securities to certain borrowers that BFA determines to be creditworthy, including borrowers affiliated with BFA. The borrowers provide collateral that is maintained in an amount at least equal to the current market value of the securities loaned. No securities loan shall be made on behalf of the Fund if, as a result, the aggregate value of all securities loaned by the Fund exceeds one-thirdof the value of the Fund's total assets (including the value of the collateral received). The Fund may terminate a loan at any time and obtain the return of the securities loaned. The Fund receives, by way of substitute payment, the value of any interest or cash or non-cashdistributions paid on the loaned securities that it would have received if the securities were not on loan.

With respect to loans that are collateralized by cash, the borrower may be entitled to receive a fee based on the amount of cash collateral. The Fund is compensated by any positive difference between the amount earned on the reinvestment of cash collateral and the fee paid to the borrower. In the case of collateral other than cash, the Fund is compensated by a fee paid by the borrower equal to a percentage of the market value of the loaned securities. Any cash collateral received by the Fund for such loans, and uninvested cash, may be reinvested in certain short-term instruments either directly on behalf of the lending Fund or through one or more joint accounts or money market funds, including those affiliated with BFA; such investments are subject to investment risk.

The Fund conducts its securities lending pursuant to an exemptive order from the SEC permitting it to lend portfolio securities to borrowers affiliated with the Fund and to retain an affiliate of the Fund to act as securities lending agent. To the extent that the Fund engages in securities lending, BlackRock Institutional Trust Company, N.A. ("BTC") acts as securities lending agent for the Fund, subject to the

21

overall supervision of BFA. BTC administers the lending program in accordance with guidelines approved by the Trust's Board of Trustees (the "Board," the trustees of which are the "Trustees").

Securities lending involves exposure to certain risks, including operational risk (i.e., the risk of losses resulting from problems in the settlement and accounting process), "gap" risk (i.e., the risk of a mismatch between the return on cash collateral reinvestments and the fees the Fund has agreed to pay a borrower), foreign exchange risk (i.e., the risk of a shortfall at default when a cash collateral investment is denominated in a currency other than the currency of the assets being loaned due to movements in foreign exchange rates), and credit, legal, counterparty and market risks (including the risk that market events could lead the Fund to recall loaned securities or to lend less or not at all, which could lead to reduced securities lending revenue). If a securities lending counterparty were to default, the Fund would be subject to the risk of a possible delay in receiving collateral or in recovering the loaned securities, or to a possible loss of rights in the collateral. In the event a borrower does not return the Fund's securities as agreed, the Fund may experience losses if the proceeds received from liquidating the collateral do not at least equal the value of the loaned security at the time the collateral is liquidated, plus the transaction costs incurred in purchasing replacement securities. This event could trigger adverse tax consequences for the Fund. The Fund could lose money if its short-term investment of the collateral declines in value over the period of the loan. Substitute payments received by the Fund representing dividends paid on securities loaned out by the Fund will not be considered qualified dividend income. BTC will take into account the tax effects on shareholders caused by this difference in connection with the Fund's securities lending program. Substitute payments received on tax-exemptsecurities loaned out will not be tax-exemptincome. There could also be changes in the status of issuers under applicable laws and regulations, including tax regulations, that may impact the regulatory or tax treatment of loaned securities and could, for example, result in a delay in the payment of dividend equivalent payments owed to the Fund (as permitted by applicable law).

Regulations adopted by global prudential regulators that are now in effect require certain bank-regulated counterparties and certain of their affiliates to include in certain financial contracts, including many securities lending agreements, terms that delay or restrict the rights of counterparties, such as the Fund, to terminate such agreements, foreclose upon collateral, exercise other default rights or restrict transfers of credit support in the event that the counterparty and/or its affiliates are subject to certain types of resolution or insolvency proceedings. It is possible that these new requirements, as well as potential additional government regulation and other developments in the market, could adversely affect the Fund's ability to terminate existing securities lending agreements or to realize amounts to be received under such agreements.

Master Limited Partnerships. The Fund may invest in publicly traded master limited partnerships ("MLPs") which are limited partnerships or limited liability companies taxable as partnerships. MLPs may derive income and gains from the exploration, development, mining or production, processing, refining, transportation (including pipelines transporting gas, oil, or products thereof), or the marketing of any mineral or natural resources. MLPs generally have two classes of owners, the general partner and limited partners. When investing in an MLP, the Fund intends to purchase publicly traded common units issued to limited partners of the MLP. The general partner is typically owned by a major energy company, an investment fund, the direct management of the MLP or is an entity owned by one or more of such parties. The general partner may be structured as a private or publicly traded corporation or other entity. The general partner typically controls the operations and management of the MLP through an up to 2% equity interest in the MLP plus, in many cases, ownership of common units and subordinated units. Limited partners own the remainder of the partnership, through ownership of common units, and have a limited role in the partnership's operations and management.

MLPs are typically structured such that common units and general partner interests have first priority to receive quarterly cash distributions up to an established minimum amount ("minimum quarterly

22

distributions" or "MQD"). Common and general partner interests also accrue arrearages in distributions to the extent the MQD is not paid. Once common and general partner interests have been paid, subordinated units receive distributions of up to the MQD; however, subordinated units do not accrue arrearages. Distributable cash in excess of the MQD paid to both common and subordinated units is distributed to both common and subordinated units generally on a pro rata basis. The general partner is also eligible to receive incentive distributions if the general partner operates the business in a manner which results in distributions paid per common unit surpassing specified target levels. As the general partner increases cash distributions to the limited partners, the general partner receives an increasingly higher percentage of the incremental cash distributions. A common arrangement provides that the general partner can reach a tier where it receives 50% of every incremental dollar paid to common and subordinated unit holders. These incentive distributions encourage the general partner to streamline costs, increase capital expenditures and acquire assets in order to increase the partnership's cash flow and raise the quarterly cash distribution in order to reach higher tiers. Such results benefit all security holders of the MLP.

MLP common units represent a limited partnership interest in the MLP. Common units are listed and traded on U.S. securities exchanges, with their value fluctuating predominantly based on prevailing market conditions and the success of the MLP. Unlike owners of common stock of a corporation, owners of common units have limited voting rights and have no ability to annually elect directors. In the event of liquidation, common units have preference over subordinated units, but not over debt or preferred units, to the remaining assets of the MLP.

Merger Transaction Risk.The Fund may buy stock of the target company in an announced merger transaction prior to the consummation of such transaction. In that circumstance, the Fund would expect to receive an amount (whether in cash, stock of the acquiring company or a combination of both) in excess of the purchase price paid by the Fund for the target company's stock. However, the Fund is subject to the risk that the merger transaction may be canceled, delayed or restructured, in which case the Fund's holding of the target company's stock may not result in any profit for the Fund and may lose significant value.

Municipal Securities. The Fund invests in securities issued in the U.S. market by U.S. states and territories, municipalities and other political subdivisions, agencies, authorities and instrumentalities of states and multi-state agencies or authorities ("municipal securities"), the interest payments of which are not subject to U.S. federal income tax. The municipal securities which the Fund may purchase include general obligation bonds and limited obligation bonds (or "Revenue Bonds"), including industrial development bonds issued pursuant to former U.S. federal tax law.

General obligation bonds are obligations involving the credit of an issuer possessing taxing power and are payable from such issuer's general revenues and not from any particular source. Revenue Bonds are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise or other specific revenue source. Revenue Bonds that are issued to finance a particular project often depend on revenues from that project to make principal and interest payments. Adverse conditions and developments affecting a particular project can result in lower revenues to the issuer of the municipal securities. Additionally, the market values of Revenue Bonds may decline in times of higher inflation to the extent that revenues are fixed income streams. In other instances, the prices that certain Revenue Bond issuers are able to charge users of their assets may be linked to inflation, whether by government regulation, contractual arrangement or other factors. In this case, changes in the rate of inflation may affect the issuer's revenues. Additionally, rising interest rates could result in higher costs of capital for issuers of both general obligation bonds and Revenue Bonds, which could negatively impact their ability to meet payment obligations.

The market for municipal bonds may be less liquid than for taxable bonds. This means that it may be harder to buy and sell municipal securities, especially on short notice, than non-municipalsecurities. In

23

addition, the municipal securities market is generally characterized as a buy and hold investment strategy. As a result, the accessibility of municipal securities in the market is generally greater closer to the original date of issue of the securities and lessens as the securities move further away from such issuance date.

Some longer-term municipal securities give the investor the right to "put" or sell the security at par (face value) within a specified number of days following the investor's request -usually one to seven days. This demand feature enhances a security's liquidity by shortening its effective maturity and enables it to trade at a price equal to or very close to par. If a demand feature terminates prior to being exercised, the Fund would hold the longer-term security, which could experience substantially more volatility.

Municipal securities are subject to credit and market risk. Generally, prices of higher quality issues tend to fluctuate more with changes in market interest rates than prices of lower quality issues and prices of longer maturity issues tend to fluctuate more than prices of shorter maturity issues.

Prices and yields on municipal securities are dependent on a variety of factors, including general money-market conditions, the financial condition of the issuer, general conditions of the municipal security market, the size of a particular offering, the maturity of the obligation and the rating of the issue. A number of these factors, including the ratings of particular issues, are subject to change from time to time. Information about the financial condition of an issuer of municipal securities may not be as extensive as that which is made available by corporations whose securities are publicly-traded. As a result, municipal securities may be more difficult to value than securities of public corporations.

Obligations of issuers of municipal securities are subject to insolvency concerns and, unlike obligations of corporate issuers, may not be subject to resolution in the event of insolvency or default through a bankruptcy proceeding. The U.S. Congress or state legislatures may seek to extend the time for payment of principal or interest, or both, or to impose other constraints upon enforcement of such obligations. In addition, municipal securities are subject to the risk that their tax treatment could be changed, thereby affecting the value of outstanding municipal securities. There is also the possibility that as a result of litigation or other conditions, such as passing of a referendum, the power or ability of issuers to meet their obligations for the payment of interest and principal on their municipal securities may be materially affected or their obligations may be found to be invalid or unenforceable. Such litigation or conditions may from time to time have the effect of introducing uncertainties in the market for municipal securities or certain segments thereof, or of materially affecting the credit risk with respect to particular bonds. Adverse economic, business, legal or political developments might affect all or a substantial portion of the Fund's municipal securities in the same manner.

Non-Diversification Risk.The Fund is classified as "non-diversified." This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S.Securities.Certain obligations or securities of non-U.S.issuers may be deemed to be located in a particular country if: (i) the principal trading market for the security is in such country, (ii) the issuer is organized under the laws of such country, (iii) the issuer derives at least 50% of its revenues or profits from such country or has at least 50% of its assets situated in such country or, (iv) the issuer is the government of the particular country. If your Fund shares are loaned pursuant to securities lending arrangements, you may lose the ability to use any non-U.S.tax credits passed through by the Fund or to treat Fund dividends (paid while the shares are held by the borrower) as qualified dividends. Regarding a short sale with respect to shares of the Fund, substitute payments made to the lender of such shares may not be deductible under certain circumstances. Consult your financial intermediary or tax advisor.

Preferred Stock. The Fund may invest in preferred stocks. Preferred stock has a preference over common stock in liquidation (and generally dividends as well) but is subordinated to the liabilities of the

24

issuer in all respects. As a general rule, the market value of preferred stock with a fixed dividend rate and no conversion element varies inversely with interest rates and perceived credit risk, while the market price of convertible preferred stock generally also reflects some element of conversion value. Because preferred stock is junior to debt securities and other obligations of the issuer, deterioration in the credit quality of the issuer will cause greater changes in the value of a preferred stock than in a more senior debt security with similar stated yield characteristics. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer's board of directors. Preferred stock also may be subject to optional or mandatory redemption provisions.

Trust Preferred Securities. The Fund may invest in trust preferred securities. Trust preferred securities are typically issued by corporations, generally in the form of interest bearing notes with preferred securities characteristics, or by an affiliated business trust of a corporation, generally in the form of beneficial interests in subordinated debentures or similarly structured securities. The trust preferred securities market consists of both fixed and adjustable coupon rate securities that are either perpetual in nature or have stated maturity dates.

Trust preferred securities are typically junior and fully subordinated liabilities of an issuer and benefit from a guarantee that is junior and fully subordinated to the other liabilities of the guarantor. In addition, trust preferred securities typically permit an issuer to defer the payment of income for five years or more without triggering an event of default. Because of their subordinated position in the capital structure of an issuer, the ability to defer payments for extended periods of time without default consequences to the issuer, and certain other features (such as restrictions on common dividend payments by the issuer or ultimate guarantor when full cumulative payments on the trust preferred securities have not been made), these trust preferred securities are often treated as close substitutes for traditional preferred securities, both by issuers and investors.

Trust preferred securities include but are not limited to trust originated preferred securities ("TOPRS®"); monthly income preferred securities ("MIPS®"); quarterly income bond securities ("QUIBS®" ); quarterly income debt securities ("QUIDS®"); quarterly income preferred securities ("QUIPSSM"); corporate trust securities ("CORTS®"); public income notes ("PINES®"); and other trust preferred securities.

Trust preferred securities are typically issued with a final maturity date, although some are perpetual in nature. In certain instances, a final maturity date may be extended and/or the final payment of principal may be deferred at the issuer's option for a specified time without default. No redemption can typically take place unless all cumulative payment obligations have been met, although issuers may be able to engage in open-market repurchases without regard to whether all payments have been paid.

Many trust preferred securities are issued by trusts or other special purpose entities established by operating companies and are not a direct obligation of an operating company. At the time the trust or special purpose entity sells such preferred securities to investors, it purchases debt of the operating company (with terms comparable to those of the trust or special purpose entity securities), which enables the operating company to deduct for tax purposes the interest paid on the debt held by the trust or special purpose entity. The trust or special purpose entity is generally required to be treated as transparent for U.S. federal income tax purposes such that the holders of the trust preferred securities are treated as owning beneficial interests in the underlying debt of the operating company. Accordingly, payments on the trust preferred securities are treated as interest rather than dividends for U.S. federal income tax purposes. The trust or special purpose entity in turn would be a holder of the operating company's debt and would have priority with respect to the operating company's earnings and profits over the operating company's common shareholders, but would typically be subordinated to other classes of the operating company's debt. Typically a preferred share has a rating that is slightly below that of its corresponding operating company's senior debt securities.

25

Privately-Issued Securities. The Fund may invest in privately-issued securities, including those that may be resold only in accordance with Rule 144A or Regulation S under the 1933 Act ("Restricted Securities"). Restricted Securities are not publicly-traded and are subject to a variety of restrictions, which limit a purchaser's ability to acquire or resell such securities. Accordingly, the liquidity of the market for specific Restricted Securities may vary. Delay or difficulty in selling such securities may result in a loss to the Fund.

The Board has adopted policies and procedures and appointed BFA as the administrator of the Liquidity Program (as defined below), which includes the assessment of the liquidity of Restricted Securities. In making determinations regarding the liquidity of a Restricted Security, BFA will take into account relevant market, trading and investment-specific considerations. Additional characteristics that may be considered in determining the liquidity of Restricted Securities include: (a) the existence of an active market, including whether the security is listed on an exchange as well as the number, diversity and quality of market participants; (b) frequency of trades or quotes; and (c) restrictions on trading.

Ratings.An investment-grade rating generally means the security or issuer is rated investment-grade by one or more of Moody's, S&P Global Ratings, Fitch, or another credit rating agency designated as a NRSRO by the SEC, or is unrated but considered to be of equivalent quality by BFA. Generally, bonds rated Baa3 or above by Moody's or BBB- orabove by S&P Global Ratings and Fitch are considered "investment-grade" securities, bonds rated Baa are considered medium grade obligations subject to moderate credit risk and may possess certain speculative characteristics, while bonds rated BBB are regarded as having adequate capacity to meet financial commitments. In recent years, the United States and certain other countries experienced a credit rating downgrade; these downgrades or additional downgrades in the future may result in the deterioration of investor confidence.

Subsequent to purchase by the Fund, a rated security may cease to be rated or its rating may be reduced below an investment-grade rating. Bonds rated below Baa3 by Moody's or BBB- byS&P Global Ratings or Fitch are generally considered below investment-grade quality and are obligations of issuers that are generally considered predominantly speculative with respect to the issuer's capacity to pay interest and repay principal according to the terms of the obligation and, therefore, carry greater investment risk, including the possibility of issuer default and bankruptcy and increased market price volatility. Please see Appendix B of this SAI for a description of each rating category of Moody's, S&P Global Ratings and Fitch and BFA's treatment of investments that are not rated by any of the rating agencies.

Real Estate Investment Trusts ("REITs").In pursuing its investment strategy, the Fund may invest in shares of REITs. REITs possess certain risks which differ from an investment in common stocks. REITs are financial vehicles that pool investor's capital to purchase or finance real estate. REITs may concentrate their investments in specific geographic areas or in specific property types, i.e., hotels, shopping malls, residential complexes and office buildings.

REITs are subject to management fees and other expenses, and so the Fund that invests in REITs will bear its proportionate share of the costs of the REITs' operations. There are three general categories of REITs: Equity REITs,

Mortgage REITs and Hybrid REITs. Equity REITs invest primarily in direct fee ownership or leasehold ownership of real property; they derive most of their income from rents. Mortgage REITs invest mostly in mortgages on real estate, which may secure construction, development or long-term loans; the main source of their income is mortgage interest payments. Hybrid REITs hold both ownership and mortgage interests in real estate.

26

Investing in REITs involves certain unique risks in addition to those risks associated with investing in the real estate industry in general. The market value of REIT shares and the ability of the REITs to distribute income may be adversely affected by several factors, including rising interest rates, changes in the national, state and local economic climate and real estate conditions, perceptions of prospective tenants of the safety, convenience and attractiveness of the properties, the ability of the owners to provide adequate management, maintenance and insurance, the cost of complying with the Americans with Disabilities Act, increased competition from new properties, the impact of present or future environmental legislation and compliance with environmental laws, failing to maintain their exemptions from registration under the Investment Company Act, changes in real estate taxes and other operating expenses, adverse changes in governmental rules and fiscal policies, adverse changes in zoning laws and other factors beyond the control of the issuers of the REITs. In addition, distributions received by the Fund from REITs may consist of dividends, capital gains and/or return of capital. As REITs generally pay a higher rate of dividends (on a pre-taxbasis) than operating companies, to the extent application of the Fund's investment strategy results in the Fund investing in REIT shares, the percentage of the Fund's dividend income received from REIT shares will likely exceed the percentage of the Fund's portfolio which is comprised of REIT shares. Ordinary REIT dividends received by the Fund and distributed to the Fund's shareholders will generally be taxable as ordinary income and will not constitute "qualified dividend income." However, for tax years beginning after December 31, 2017 and before January 1, 2026, a non-corporatetaxpayer who is a direct REIT shareholder may claim a 20% "qualified business income" deduction for ordinary REIT dividends, and a regulated investment company may report dividends as eligible for this deduction to the extent the regulated investment company's income is derived from ordinary REIT dividends (reduced by allocable regulated investment company expenses). A shareholder may treat the dividends as such provided the regulated investment company and the shareholder satisfy applicable holding period requirements.

REITs (especially mortgage REITs) are also subject to interest rate risk. Rising interest rates may cause REIT investors to demand a higher annual yield, which may, in turn, cause a decline in the market price of the equity securities issued by a REIT. Rising interest rates also generally increase the costs of obtaining financing, which could cause the value of the Fund's REIT investments to decline. During periods when interest rates are declining, mortgages are often refinanced. Refinancing may reduce the yield on investments in mortgage REITs. In addition, since REITs depend on payment under their mortgage loans and leases to generate cash to make distributions to their shareholders, investments in REITs may be adversely affected by defaults on such mortgage loans or leases.

Investing in certain REITs, which often have small market capitalizations, may also involve the same risks as investing in other small capitalization companies. REITs may have limited financial resources and their securities may trade less frequently and in limited volume and may be subject to more abrupt or erratic price movements than larger company securities. Historically, small capitalization stocks, such as REITs, have been more volatile in price than the larger capitalization stocks such as those included in the S&P 500 Index. The management of a REIT may be subject to conflicts of interest with respect to the operation of the business of the REIT and may be involved in real estate activities competitive with the REIT. REITs may own properties through joint ventures or in other circumstances in which the REIT may not have control over its investments. REITs may incur significant amounts of leverage.

Regulation Regarding Derivatives. The CFTC subjects advisers to registered investment companies to regulation by the CFTC if a fund that is advised by the adviser either (i) invests, directly or indirectly, more than a prescribed level of its liquidation value in CFTC-regulated futures, options and swaps ("CFTC Derivatives") or (ii) markets itself as providing investment exposure to such instruments. The CFTC also subjects advisers to registered investment companies to regulation by the CFTC if the registered investment company invests in one or more commodity pools. NDFs and cash-settled currency forwards as well as futures, options on futures, currency options and swaps entered into by

27

the Fund will be treated as CFTC Derivatives for these purposes. Physically-settled foreign currency forward contracts will generally be treated as CFTC Derivatives however, these contracts are not treated as CFTC regulated-swaps and are not subject to certain of the CFTC's rules with respect to swaps. To the extent the Fund uses CFTC Derivatives, it intends to do so below such prescribed levels and intends not to market itself as a "commodity pool" or a vehicle for trading such instruments.

BFA has claimed an exclusion from the definition of the term "commodity pool operator" under the CEA pursuant to Rule 4.5 under the CEA with respect to the Fund . BFA is not, therefore, subject to registration or regulation as a "commodity pool operator" under the CEA with respect to the Fund.

Derivative contracts, including, without limitation, swaps, currency forwards, and non-deliverable forwards, are subject to regulation under the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act") in the U.S. and under comparable regimes in Europe, Asia and other non-U.S.jurisdictions. Swaps, non-deliverable forwards and certain other derivatives traded in the OTC market are subject to variation margin and initial margin requirements. Implementation of the margining and other provisions of the Dodd-Frank Act regarding clearing, mandatory trading, reporting and documentation of swaps and other derivatives have impacted and may continue to impact the costs to the Fund of trading these instruments and, as a result, may affect returns to investors in the Fund.

Rule 18f-4 under the Investment Company Act permits the Fund to enter into Derivatives Transactions (as defined below) and certain other transactions notwithstanding the restrictions on the issuance of "senior securities" under Section 18 of the Investment Company Act. Section 18 of the Investment Company Act, among other things, prohibits open-end funds, including the Fund, from issuing or selling any "senior security," other than borrowing from a bank (subject to a requirement to maintain 300% "asset coverage").

Under Rule 18f-4, "Derivatives Transactions" include the following: (1) any swap, security-based swap (including a contract for differences), futures contract, forward contract, option (excluding purchased options), any combination of the foregoing, or any similar instrument, under which the Fund is or may be required to make any payment or delivery of cash or other assets during the life of the instrument or at maturity or early termination, whether as margin or settlement payment or otherwise; (2) any short sale borrowing; (3) reverse repurchase agreements and similar financing transactions (e.g., recourse and non-recourse tender option bonds, and borrowed bonds), if the Fund elects to treat these transactions as Derivatives Transactions under Rule 18f-4; and (4) when-issued or forward-settling securities (e.g., firm and standby commitments, including to-be-announced ("TBA") commitments, and dollar rolls) and non-standard settlement cycle securities, unless the Fund intends to physically settle the transaction and the transaction will settle within 35 days of its trade date (the "Delayed-Settlement Securities Provision").

Unless the Fund is relying on the Limited Derivatives User Exception (as defined below), the Fund must comply with Rule 18f-4 with respect to its Derivatives Transactions. Rule 18f-4, among other things, requires the Fund to adopt and implement a comprehensive written derivatives risk management program ("DRMP") and comply with a relative or absolute limit on Fund leverage risk calculated based on value-at-risk ("VaR"). The DRMP is administered by a "derivatives risk manager," who is appointed by the Board, including a majority of Independent Directors/Trustees, and periodically reviews the DRMP and reports to the Board.

Rule 18f-4 provides an exception from the DRMP, VaR limit and certain other requirements if the Fund's "derivatives exposure" (as defined in Rule 18f-4) is limited to 10% of its net assets (as calculated in accordance with Rule 18f-4) and the Fund adopts and implements written policies and procedures reasonably designed to manage its derivatives risks (the "Limited Derivatives User Exception").

28

Repurchase Agreements. A repurchase agreement is an instrument under which the purchaser (i.e., the Fund) acquires a security and the seller agrees, at the time of the sale, to repurchase the security at a mutually agreed-upon time and price, thereby determining the yield during the purchaser's holding period. Repurchase agreements may be construed to be collateralized loans by the purchaser to the seller secured by the securities transferred to the purchaser. If a repurchase agreement is construed to be a collateralized loan, the underlying securities will not be considered to be owned by the Fund but only to constitute collateral for the seller's obligation to pay the repurchase price, and, in the event of a default by the seller, the Fund may suffer time delays and incur costs or losses in connection with the disposition of the collateral.

In any repurchase transaction, the collateral for a repurchase agreement may include: (i) cash items; (ii) obligations issued by the U.S. government or its agencies or instrumentalities; or (iii) obligations that, at the time the repurchase agreement is entered into, are determined to (A) have exceptionally strong capacity to meet their financial obligations and (B) are sufficiently liquid such that they can be sold at approximately their carrying value in the ordinary course of business within seven days.

Repurchase agreements pose certain risks for the Fund, should it decide to utilize them. Such risks are not unique to the Fund, but are inherent in repurchase agreements. The Fund seeks to minimize such risks, but because of the inherent legal uncertainties involved in repurchase agreements, such risks cannot be eliminated. Lower quality collateral and collateral with a longer maturity may be subject to greater price fluctuations than higher quality collateral and collateral with a shorter maturity. If the repurchase agreement counterparty were to default, lower quality collateral may be more difficult to liquidate than higher quality collateral. Should the counterparty default and the amount of collateral not be sufficient to cover the counterparty's repurchase obligation, the Fund would likely retain the status of an unsecured creditor of the counterparty (i.e., the position the Fund would normally be in if it were to hold, pursuant to its investment policies, other unsecured debt securities of the defaulting counterparty) with respect to the amount of the shortfall. As an unsecured creditor, the Fund would be at risk of losing some or all of the principal and income involved in the transaction.

Rule 18f-4 under the Investment Company Act permits a Fund to enter into reverse repurchase agreements and similar financing transactions (e.g., recourse and non-recourse tender option bonds, borrowed bonds) notwithstanding the limitation on the issuance of senior securities in Section 18 of the Investment Company Act, provided that the Fund either (i) complies with the 300% asset coverage ratio with respect to such transactions and any other borrowings in the aggregate, or (ii) treats such transactions as Derivatives Transactions under Rule 18f-4. See "-Regulation Regarding Derivatives" above.

Reverse Repurchase Agreements. Reverse repurchase agreements involve the sale of securities with an agreement to repurchase the securities at an agreed-upon price, date and interest payment and have the characteristics of borrowing. Generally, the effect of such transactions is that the Fund can recover all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement, while in many cases the Fund is able to keep some of the interest income associated with those securities. Such transactions are advantageous only if the Fund has an opportunity to earn a rate of interest on the cash derived from these transactions that is greater than the interest cost of obtaining the same amount of cash. Opportunities to realize earnings from the use of the proceeds equal to or greater than the interest required to be paid may not always be available, and the Fund intends to use the reverse repurchase technique only when BFA believes it will be advantageous to the Fund. The use of reverse repurchase agreements may exaggerate any increase or decrease in the value of the Fund's assets. The use of reverse repurchase agreements is a form of leverage, and the proceeds obtained by the Fund through reverse repurchase agreements may be invested in additional securities.

Rule 18f-4 under the Investment Company Act permits the Fund to enter into reverse repurchase agreements and similar financing transactions (e.g., recourse and non-recourse tender option bonds, borrowed bonds) notwithstanding the limitation on the issuance of senior securities in Section 18 of the Investment Company Act, provided that the Fund either (i) complies with the 300% asset coverage ratio with respect to such transactions and any other borrowings in the aggregate, or (ii) treats such transactions as Derivatives Transactions under Rule 18f-4. See "-Regulation Regarding Derivatives" above.

Rights Offerings and Warrants to Purchase.The Fund may participate in rights offerings and may purchase warrants, which are privileges issued by corporations enabling the owners to subscribe to and purchase a specified number of shares of the corporation at a specified price during a specified period of time. Subscription rights normally have a short life span to expiration. The purchase of rights or warrants involves the risk that the Fund could lose the purchase value of a right or warrant if the right to subscribe to additional shares is not exercised prior to the rights' and warrants' expiration. Also, the purchase of rights and/or warrants involves the risk that the effective price paid for the right and/or warrant added to the subscription price of the related security may exceed the value of the subscribed security's market price such as when there is no movement in the level of the underlying security. Buying a warrant does not make the Fund a shareholder of the underlying stock. The warrant holder has no voting or dividend rights with respect to the underlying stock. A warrant does not carry any right to assets of the issuer, and for this reason investments in warrants may be more speculative than other equity-based investments.

Securities of Investment Companies. The Fund may invest in the securities of other investment companies (including money market funds) to the extent permitted by law, regulation, exemptive order or SEC staff guidance. Under the 1940 Act, a fund's investment in investment companies is limited to, subject to certain exceptions, (i) 3% of the total outstanding voting stock of any one investment company, (ii) 5% of the fund's total assets with respect to any one investment company, and (iii) 10% of the fund's total assets with respect to investment companies in the aggregate. Other investment companies in which the Fund invests can be expected to incur fees and expenses for operations, such as investment advisory and administration fees, which would be in addition to those incurred by the Fund. Pursuant to guidance issued by the SEC staff, fees and expenses of money market funds used for cash collateral received in connection with loans of securities are not treated as Acquired Fund Fees and Expenses, which reflect the Fund's pro ratashare of the fees and expenses incurred indirectly as a result of investing in other investment companies (as disclosed in the Prospectus, as applicable).

Short Sales.The Fund may make short sales of securities, either as a hedge against potential declines in value of a portfolio security or to realize appreciation when a security that the Fund does not own declines in value. When the Fund makes a short sale, it borrows the security sold short and delivers it to the broker-dealer through which it made the short sale. The Fund may have to pay a fee to borrow particular securities and is often obligated to turn over any payments received on such borrowed securities to the lender of the securities.

The Fund secures its obligation to replace the borrowed security by depositing collateral with the broker-dealer, usually in cash, U.S. government securities or other liquid securities similar to those borrowed. With respect to uncovered short positions, the Fund is required to deposit similar collateral with its custodian, if necessary, to the extent that the value of both collateral deposits in the aggregate is at all times equal to at least 100% of the current market value of the security sold short. Depending on arrangements made with the broker-dealer from which the Fund borrowed the security, regarding payment received by the Fund on such security, the Fund may not receive any payments (including interest) on its collateral deposited with such broker-dealer.

The Fund must comply with Rule 18f-4 under the Investment Company Act with respect to its short sale borrowings, which are considered Derivatives Transactions under the Rule. See "-Regulation Regarding Derivatives" above.

30

Short-Term Instruments and Temporary Investments. The Fund may invest in short-term instruments, including money market instruments, on an ongoing basis to provide liquidity or for other reasons. Money market instruments are generally short-term investments that may include, but are not limited to: (i) shares of money market funds (including those advised by BFA or otherwise affiliated with BFA); (ii) obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities (including government-sponsored enterprises); (iii) negotiable certificates of deposit, bankers' acceptances, fixed-time deposits and other obligations of U.S. and non-U.S.banks (including non-U.S.branches) and similar institutions; (iv) commercial paper rated, at the date of purchase, "Prime-1"by Moody's, "F-1"by Fitch or "A-1"by S&P Global Ratings, or if unrated, of comparable quality as determined by BFA; (v) non-convertiblecorporate debt securities (e.g., bonds and debentures) with remaining maturities at the date of purchase of not more than 397 days and that have been determined to present minimal credit risks, in accordance with the requirements set forth in Rule 2a-7under the 1940 Act; (vi) repurchase agreements; and (vii) short-term U.S. dollar-denominated obligations of non-U.S.banks (including U.S. branches) that, in the opinion of BFA, are of comparable quality to obligations of U.S. banks that may be purchased by the Fund. Any of these instruments may be purchased on a current or forward-settled basis. Time deposits are non-negotiabledeposits maintained in banking institutions for specified periods of time at stated interest rates. Bankers' acceptances are time drafts drawn on commercial banks by borrowers, usually in connection with international transactions.

Special Purpose Acquisition Companies. The Fund may invest in stock, warrants, rights and other interests issued by special purpose acquisition companies ("SPACs") or similar special purpose entities that pool funds to seek potential acquisition opportunities, including the "founder's" shares and warrants described below. A SPAC is a publicly traded company that raises investment capital via an IPO for the purpose of identifying and acquiring one or more operating businesses or assets. In connection with forming a SPAC, the SPAC's sponsors acquire "founder's" shares, generally for nominal consideration, and warrants that will result in the sponsors owning a specified percentage (typically 20%) of the SPAC's outstanding common stock upon completion of the IPO. At the time a SPAC conducts an IPO, it has selected a management team but has not yet identified a specific acquisition opportunity.

Unless and until an acquisition is completed, a SPAC generally invests its assets in U.S. government securities, money market securities and cash. If an acquisition that meets the requirements for the SPAC is not completed within a pre-establishedperiod of time, the invested funds are returned to the SPAC's public shareholders, the warrants expire, and the "founder's" shares and such warrants become worthless. Because SPACs and similar entities are in essence "blank check" companies without operating histories or ongoing business operations (other than identifying and pursuing acquisitions), the potential for the long term capital appreciation of their securities is particularly dependent on the ability of the SPAC's management to identify and complete a profitable acquisition. There is no guarantee that the SPACs in which the Fund invests will complete an acquisition or that any acquisitions completed by the SPACs in which the Fund invests will be profitable. Some SPACs may pursue acquisitions only within certain industries or regions, which may ultimately lead to an increase in the volatility of their prices following the acquisition. In addition, some of these securities may be considered illiquid and/or subject to restrictions on resale.

Standby Commitment Agreements. Standby commitment agreements commit the Fund, for a stated period of time, to purchase a stated amount of securities that may be issued and sold to that Fund at the option of the issuer. The price of the security is fixed at the time of the commitment. At the time of entering into the agreement, the Fund is paid a commitment fee, regardless of whether or not the security is ultimately issued. The Fund will enter into such agreements for the purpose of investing in the security underlying the commitment at a price that is considered advantageous to the Fund.

31

There can be no assurance that the securities subject to a standby commitment will be issued, and the value of the security, if issued, on the delivery date may be more or less than its purchase price. Since the issuance of the security underlying the commitment is at the option of the issuer, the Fund may bear the risk of a decline in the value of such security and may not benefit from an appreciation in the value of the security during the commitment period.

The purchase of a security pursuant to a standby commitment agreement and the related commitment fee will be recorded on the date on which the security can reasonably be expected to be issued, and the value of the security thereafter will be reflected in the calculation of the Fund's NAV. The cost basis of the security will be adjusted by the amount of the commitment fee. In the event the security is not issued, the commitment fee will be recorded as income on the expiration date of the standby commitment.

Stand-bycommitments will only be entered into with dealers, banks and broker-dealers which, in the Investment Adviser's opinion, present minimal credit risks. The Fund will acquire stand-bycommitments solely to facilitate portfolio liquidity and not to exercise its rights thereunder for trading purposes. Stand-bycommitments will be valued at zero in determining NAV. Accordingly, where the Fund pays directly or indirectly for a stand-bycommitment, its cost will be reflected as an unrealized loss for the period during which the commitment is held by the Fund and will be reflected as a realized gain or loss when the commitment is exercised or expires.

Stripped Securities. Stripped securities are created when the issuer separates the interest and principal components of an instrument and sells them as separate securities. In general, one security is entitled to receive the interest payments on the underlying assets (the interest only or "IO" security) and the other to receive the principal payments (the principal only or "PO" security). Some stripped securities may receive a combination of interest and principal payments. The yields to maturity on IOs and POs are sensitive to the expected or anticipated rate of principal payments (including prepayments) on the related underlying assets, and principal payments may have a material effect on yield to maturity. If the underlying assets experience greater than anticipated prepayments of principal, the Fund may not fully recoup its initial investment in IOs. Conversely, if the underlying assets experience less than anticipated prepayments of principal, the yield on POs could be adversely affected. Stripped securities may be highly sensitive to changes in interest rates and rates of prepayment.

Structured Notes. Structured notes and other related instruments purchased by the Fund are generally privately negotiated debt obligations where the principal and/or interest is determined by reference to the performance of a specific asset, benchmark asset, market or interest rate ("reference measure"). Issuers of structured notes include corporations and banks. The interest rate or the principal amount payable upon maturity or redemption may increase or decrease, depending upon changes in the value of the reference measure. The terms of a structured note may provide that, in certain circumstances, no principal is due at maturity and, therefore, may result in a loss of invested capital by the Fund. The interest and/or principal payments that may be made on a structured product may vary widely, depending on a variety of factors, including the volatility of the reference measure.

Structured notes may be positively or negatively indexed, so the appreciation of the reference measure may produce an increase or a decrease in the interest rate or the value of the principal at maturity. The rate of return on structured notes may be determined by applying a multiplier to the performance or differential performance of reference measures. Application of a multiplier involves leverage that will serve to magnify the potential for gain and the risk of loss.

The purchase of structured notes exposes the Fund to the credit risk of the issuer of the structured product. Structured notes may also be more volatile, less liquid, and more difficult to price accurately than less complex securities and instruments or more traditional debt securities. The secondary market

32

for structured notes could be illiquid making them difficult to sell when the Fund determines to sell them. The possible lack of a liquid secondary market for structured notes and the resulting inability of the Fund to sell a structured note could expose the Fund to losses and could make structured notes more difficult for the Fund to value accurately.

Swap Agreements. Swap agreements are contracts between parties in which one party agrees to make periodic payments to the other party based on a pre-determinedunderlying investment or notional amount. In return, the other party agrees to make periodic payments to the first party based on the return (or a differential in rate of return) earned or realized on the underlying investment or notional amount. Swap agreements will usually be performed on a net basis, with the Fund receiving or paying only the net amount of the two payments. The net amount of the excess, if any, the Fund's obligations over its entitlements with respect to each swap is accrued on a daily basis.

The Fund may enter into swap agreements, including currency swaps, interest rate swaps and index swaps. The use of swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. These transactions generally do not involve the delivery of securities or other underlying assets.

U.S. Agency Mortgage-Backed Securities Risk. The Fund invest in securities backed by pools of mortgages issued or guaranteed by the U.S. government or one of its agencies or sponsored entities, including Government National Mortgage Association ("Ginnie Mae"), Federal National Mortgage Association ("Fannie Mae"), and the Federal Home Loan Mortgage Corporation ("Freddie Mac"). The market for mortgage-backed securities ("MBS") has been adversely affected by the value of those MBS held and/or issued by these agencies and sponsored entities. If a U.S. government agency or sponsored entity issues securities in which the Fund invests and such issuer is unable to meet its obligations or ceases to exist, and no plan is made for the repayment of securities, the performance of the Fund will be adversely impacted.

Ginnie Mae. Established in 1968, Ginnie Mae is a wholly owned U.S. government corporation within the U.S. Department of Housing and Urban Development. Ginnie Mae is authorized to guarantee, with the backing of the full faith and credit of the U.S. government, the timely payment of principal and interest on securities issued by the institutions approved by Ginnie Mae (such as savings and loan institutions, commercial banks and mortgage banks), and backed by pools of mortgages insured by the Federal Housing Administration or guaranteed by the U.S. Department of Veterans Affairs. Ginnie Mae securities also are supported by the authority of Ginnie Mae to borrow funds from the U.S. Treasury Department to make payments under its guarantee. Any actual or potential disruption to Ginnie Mae, or the financial condition or credit of the U.S. government, could cause the value of Ginnie Mae securities to decline. In 2011, S&P Global Ratings downgraded U.S. Treasury securities from AAA rating to AA+ rating. A further downgrade of the ratings of U.S. government debt obligations, which are often used as a benchmark for other borrowing arrangements, could result in higher interest rates for individual and corporate borrowers, cause disruptions in the international bond markets and have a substantial negative effect on the U.S. economy. A downgrade of U.S. Treasury securities from another ratings agency or a further downgrade below AA+ rating by S&P Global Ratings may cause the value of Ginnie Mae securities to decline.

Fannie Mae and Freddie Mac. Fannie Mae was established as a federal agency in 1938 and in 1968 was chartered by Congress as a private shareholder-owned company. Securities issued by Fannie Mae are guaranteed as to timely payment of principal and interest by Fannie Mae. The securities are not backed by or entitled to the full faith and credit of the U.S. government, but are supported by the right of Fannie Mae to borrow from the U.S. Treasury Department. Freddie Mac is a stockholder-owned corporation chartered by Congress in 1970. Securities issued by Freddie Mac entitle the holder to timely payment of interests, which is guaranteed by Freddie Mac. Freddie Mac also guarantees either

33

ultimate collection or timely payment of all principal payments. While Freddie Mac generally does not guarantee timely payment of principal, Freddie Mac may remit the amount due on account of its guarantee of ultimate payment of principal at any time after default on an underlying mortgage, but in no event later than one year after it becomes payable. The securities are not backed by or entitled to the full faith and credit of the U.S. government or by any Federal Home Loan Banks, but are supported by the right of Freddie Mac to borrow from the U.S. Treasury Department. In 2008, the Federal Housing Finance Agency placed each of Fannie Mae and Freddie Mac into government conservatorship in an effort to provide stability in the financial markets and put the government-sponsored entities in sound and solvent condition. In addition, the U.S. Treasury Department agreed to provide Fannie Mae and Freddie Mac up to $100 billion of capital each on an as needed basis to ensure that they continue to provide liquidity to the housing and mortgage markets.

Mortgage-Backed Securities. MBS issued or guaranteed by the U.S. government or one of its agencies or sponsored entities, such as Ginnie Mae, Fannie Mae, or Freddie Mac, represent interests in pools of mortgages in which payments of both principal and interest on the securities are generally made monthly, in effect "passing through" the payments made by borrowers on the mortgage loans that underlie the securities (net of any fees paid to the issuer or guarantor of the securities). MBS differ from other forms of debt securities, which normally provide for periodic payment of interest in fixed amounts with principal payments at maturity or specified call dates, while a MBS payments provide a combination of interest and principal throughout the a bond's term. As further described below, MBS may be structured as pass-through securities or collateralized mortgage obligations ("CMOs").

MBS are subject to the general risks associated with investing in real estate securities; that is, they may lose value if the value of the underlying real estate to which a pool of mortgages relates declines. In addition, investments in MBS involve certain specific risks. These risks include the failure of a party to meet its commitments under the related operative documents, adverse interest rate changes and the effects of prepayments on mortgage cash flows. The value of MBS, like that of traditional fixed-income securities, typically increases when interest rates fall and decreases when interest rates rise. However, MBS differ from traditional fixed-income securities because of their potential for prepayment without penalty. The price paid by the Fund for its MBS, the yield the Fund expects to receive from such securities and the weighted average life of the securities are based on a number of factors, including the anticipated rate of prepayment of the underlying mortgages. In a period of declining interest rates, borrowers may prepay the underlying mortgages more quickly than anticipated, thereby reducing the yield to maturity and the average life of the MBS. Moreover, when the Fund reinvests the proceeds of a prepayment in these circumstances, it will likely receive a rate of interest that is lower than the rate on the security that was prepaid.

To the extent that the Fund purchases MBS at a premium, mortgage foreclosures and principal prepayments may result in a loss to the extent of the premium paid. If the Fund buys such securities at a discount, both scheduled payments of principal and unscheduled prepayments will increase current and total returns and will accelerate the recognition of income, which, when distributed to shareholders, will be taxable as ordinary income. In a period of rising interest rates, prepayments of the underlying mortgages may occur at a slower than expected rate, creating maturity extension risk. This particular risk may effectively change a security that was considered short- or intermediate-term at the time of purchase into a long-term security. Since the value of long-term securities generally fluctuates more widely in response to changes in interest rates than that of shorter-term securities, maturity extension risk could increase the inherent volatility of the Fund. Under certain interest rate and prepayment scenarios, the Fund may fail to recoup fully its investment in MBS notwithstanding any direct or indirect U.S. governmental or agency guarantee.

Mortgage Pass-Through Securities. Some MBS, such as U.S. agency mortgage pass-through securities, represent a right to receive principal and interest payments collected on a pool of

34

mortgages, which are passed through to security holders. In the basic mortgage pass-through structure, mortgages with similar issuer, term and coupon characteristics are collected and aggregated into a "pool" consisting of multiple mortgage loans. The pool is assigned a CUSIP number and undivided interests in the pool are traded and sold as pass-through securities. The holder of the security is entitled to a pro rata share of principal and interest payments (including unscheduled prepayments) from the pool of mortgage loans.

An investment in a specific pool of mortgage pass-through securities requires an analysis of the specific prepayment risk of mortgages within the covered pool (since mortgagors typically have the option to prepay their loans). The level of prepayments on a pool of MBS is difficult to predict and can impact the subsequent cash flows, value and yield of the mortgage pool. In addition, when trading specific mortgage pools, precise execution, delivery and settlement arrangements must be negotiated for each transaction.

Collateralized Mortgage Obligations. U.S. agency MBS may also be structured in the form of CMOs. CMOs are created by dividing the principal and interest payments collected on a pool of mortgages into several revenue streams ("tranches") with different priority rights to portions of the underlying mortgage payments. Certain CMO tranches may represent a right to receive interest only, principal only, or an amount that remains after floating-rate tranches are paid (an "inverse floater"). These securities are frequently referred to as "mortgage derivatives" and may be extremely sensitive to changes in interest rates. Interest rates on inverse floaters, for example, vary inversely with a short-term floating rate (which may be reset periodically). Interest rates on inverse floaters will decrease when short-term rates increase and will increase when shortterm rates decrease. These securities have the effect of providing a degree of investment leverage. In response to changes in market interest rates or other market conditions, the value of an inverse floater may increase or decrease at a multiple of the increase or decrease in the value of the underlying securities. If the Fund invests in CMO tranches issued by U.S. government agencies or sponsored entities and interest rates move in a manner not anticipated by BFA, it is possible that such the Fund could lose all or substantially all of its investment. Certain CMOs in which the Fund may invest may also provide a degree of investment leverage, which could cause such the Fund to lose all or substantially all of its investment.

U.S. Government Obligations. The Fund may invest in various types of U.S. government obligations. U.S. government obligations are a type of bond and include securities issued or guaranteed as to principal and interest by the U.S. government, its agencies or instrumentalities. Payment of principal and interest on U.S. government obligations (i) may be backed by the full faith and credit of the U.S. or (ii) may be backed solely by the issuing or guaranteeing agency or instrumentality itself (as with Fannie Mae, Freddie Mae and Federal Home Loan Bank notes). In the latter case, the Fund must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so. As a general matter, the value of debt instruments, including U.S. government obligations, declines when market interest rates increase and rises when market interest rates decrease. Certain types of U.S. government obligations are subject to fluctuations in yield or value due to their structure or contract terms.

Utility Industries. Risks that are intrinsic to the utility industries include difficulty in obtaining an adequate return on invested capital, difficulty in financing large construction programs during an inflationary period, restrictions on operations and increased cost and delays attributable to environmental considerations and regulation, difficulty in raising capital in adequate amounts on reasonable terms in periods of high inflation and unsettled capital markets, technological innovations that may render existing plants, equipment or products obsolete, the potential impact of natural or man-madedisasters, increased costs and reduced availability of certain types of fuel, occasional

35

reduced availability and high costs of natural gas for resale, the effects of energy conservation, the effects of a national energy policy and lengthy delays and greatly increased costs and other problems associated with the design, construction, licensing, regulation and operation of nuclear facilities for electric generation, including, among other considerations, the problems associated with the use of radioactive materials and the disposal of radioactive wastes. There are substantial differences among the regulatory practices and policies of various jurisdictions, and any given regulatory agency may make major shifts in policy from time to time. There is no assurance that regulatory authorities will, in the future, grant rate increases or that such increases will be adequate to permit the payment of dividends on common stocks issued by a utility company. Additionally, existing and possible future regulatory legislation may make it even more difficult for utilities to obtain adequate relief. Certain of the issuers of securities held in the Fund's portfolio may own or operate nuclear generating facilities. Governmental authorities may from time to time review existing policies and impose additional requirements governing the licensing, construction and operation of nuclear power plants. Prolonged changes in climatic conditions can also have a significant impact on both the revenues of an electric and gas utility as well as the expenses of a utility, particularly a hydro-based electric utility.

Utility companies in the United States and in foreign countries are generally subject to regulation. In the United States, most utility companies are regulated by state and/or federal authorities. Such regulation is intended to ensure appropriate standards of service and adequate capacity to meet public demand. Generally, prices are also regulated in the United States and in foreign countries with the intention of protecting the public while ensuring that the rate of return earned by utility companies is sufficient to allow them to attract capital in order to grow and continue to provide appropriate services. There can be no assurance that such pricing policies or rates of return will continue in the future.

The nature of regulation of the utility industries continues to evolve both in the United States and in foreign countries. In recent years, changes in regulation in the United States increasingly have allowed utility companies to provide services and products outside their traditional geographic areas and lines of business, creating new areas of competition within the industries. In some instances, utility companies are operating on an unregulated basis. Because of trends toward deregulation and the evolution of independent power producers as well as new entrants to the field of telecommunications, non-regulatedproviders of utility services have become a significant part of their respective industries. The Investment Adviser believes that the emergence of competition and deregulation will result in certain utility companies being able to earn more than their traditional regulated rates of return, while others may be forced to defend their core business from increased competition and may be less profitable. Reduced profitability, as well as new uses of funds (such as for expansion, operations or stock buybacks) could result in cuts in dividend payout rates. The Investment Adviser seeks to take advantage of favorable investment opportunities that may arise from these structural changes. Of course, there can be no assurance that favorable developments will occur in the future.

Foreign utility companies are also subject to regulation, although such regulations may or may not be comparable to those in the United States. Foreign utility companies may be more heavily regulated by their respective governments than utilities in the United States and, as in the United States, generally are required to seek government approval for rate increases. In addition, many foreign utilities use fuels that may cause more pollution than those used in the United States, which may require such utilities to invest in pollution control equipment to meet any proposed pollution restrictions. Foreign regulatory systems vary from country to country and may evolve in ways different from regulation in the United States.

The Fund's investment policies are designed to enable it to capitalize on evolving investment opportunities throughout the world. For example, the rapid growth of certain foreign economies will necessitate expansion of capacity in the utility industries in those countries. Although many foreign utility companies currently are government-owned, thereby limiting current investment opportunities for

36

the Fund, the Investment Adviser believes that, in order to attract significant capital for growth, foreign governments are likely to seek global investors through the privatization of their utility industries. Privatization, which refers to the trend toward investor ownership of assets rather than government ownership, is expected to occur in newer, faster-growing economies and in mature economies. Of course, there is no assurance that such favorable developments will occur or that investment opportunities in foreign markets will increase.

The revenues of domestic and foreign utility companies generally reflect the economic growth and development in the geographic areas in which they do business. The Investment Adviser will take into account anticipated economic growth rates and other economic developments when selecting securities of utility companies.

Electric. The electric utility industry consists of companies that are engaged principally in the generation, transmission and sale of electric energy, although many also provide other energy-related services. In the past, electric utility companies, in general, have been favorably affected by lower fuel and financing costs and the full or near completion of major construction programs. In addition, many of these companies have generated cash flows in excess of current operating expenses and construction expenditures, permitting some degree of diversification into unregulated businesses. Some electric utilities have also taken advantage of the right to sell power outside of their traditional geographic areas. Electric utility companies have historically been subject to the risks associated with increases in fuel and other operating costs, high interest costs on borrowings needed for capital construction programs, costs associated with compliance with environmental and safety regulations and changes in the regulatory climate. As interest rates declined, many utilities refinanced high cost debt and in doing so improved their fixed charges coverage. Regulators, however, lowered allowed rates of return as interest rates declined and thereby caused the benefits of the rate declines to be shared wholly or in part with customers. In a period of rising interest rates, the allowed rates of return may not keep pace with the utilities' increased costs. The construction and operation of nuclear power facilities are subject to strict scrutiny by, and evolving regulations of, the Nuclear Regulatory Commission and state agencies which have comparable jurisdiction. Strict scrutiny might result in higher operating costs and higher capital expenditures, with the risk that the regulators may disallow inclusion of these costs in rate authorizations or the risk that a company may not be permitted to operate or complete construction of a facility. In addition, operators of nuclear power plants may be subject to significant costs for disposal of nuclear fuel and for decommissioning such plants.

The rating agencies look closely at the business profile of utilities. Ratings for companies are expected to be impacted to a greater extent in the future by the division of their asset base. Electric utility companies that focus more on the generation of electricity may be assigned less favorable ratings as this business is expected to be competitive and the least regulated. On the other hand, companies that focus on transmission and distribution, which is expected to be the least competitive and the more regulated part of the business, may see higher ratings given the greater predictability of cash flow.

A number of states are considering or have enacted deregulation proposals. The introduction of competition into the industry as a result of such deregulation has at times resulted in lower revenue, lower credit ratings, increased default risk, and lower electric utility security prices. Such increased competition may also cause long-term contracts, which electric utilities previously entered into to buy power, to become "stranded assets" which have no economic value. Any loss associated with such contracts must be absorbed by ratepayers and investors. In addition, some electric utilities have acquired electric utilities overseas to diversify, enhance earnings and gain experience in operating in a deregulated environment. In some instances, such acquisitions have involved significant borrowings, which have burdened the acquirer's balance sheet. There is no assurance that current deregulation proposals will be adopted. However, deregulation in any form could significantly impact the electric utilities industry.

37

Telecommunications. The telecommunications industry today includes both traditional telephone companies, with a history of broad market coverage and highly regulated businesses, and cable companies, which began as small, lightly regulated businesses focused on limited markets. Today these two historically different businesses are converging in an industry that is trending toward larger, competitive national and international markets with an emphasis on deregulation. Companies that distribute telephone services and provide access to the telephone networks still comprise the greatest portion of this segment, but non-regulatedactivities such as wireless telephone services, paging, data transmission and processing, equipment retailing, computer software and hardware and internet services are becoming increasingly significant components as well. In particular, wireless and internet telephone services continue to gain market share at the expense of traditional telephone companies. The presence of unregulated companies in this industry and the entry of traditional telephone companies into unregulated or less regulated businesses provide significant investment opportunities with companies that may increase their earnings at faster rates than had been allowed in traditional regulated businesses. Still, increasing competition, technological innovations and other structural changes could adversely affect the profitability of such utilities and the growth rate of their dividends. Given mergers and proposed legislation and enforcement changes, it is likely that both traditional telephone companies and cable companies will continue to provide an expanding range of utility services to both residential, corporate and governmental customers.

Gas. Gas transmission companies and gas distribution companies are undergoing significant changes. In the United States, interstate transmission companies are regulated by the Federal Energy Regulatory Commission, which is reducing its regulation of the industry. Many companies have diversified into oil and gas exploration and development, making returns more sensitive to energy prices. In the recent decade, gas utility companies have been adversely affected by disruptions in the oil industry and have also been affected by increased concentration and competition. In the opinion of the Investment Adviser, however, environmental considerations could improve the gas industry outlook in the future. For example, natural gas is the cleanest of the hydrocarbon fuels, and this may result in incremental shifts in fuel consumption toward natural gas and away from oil and coal, even for electricity generation. However, technological or regulatory changes within the industry may delay or prevent this result.

Water. Water supply utilities are companies that collect, purify, distribute and sell water. In the United States and around the world the industry is highly fragmented because most of the supplies are owned by local authorities. Companies in this industry are generally mature and are experiencing little or no per capita volume growth. In the opinion of the Investment Adviser, there may be opportunities for certain companies to acquire other water utility companies and for foreign acquisition of domestic companies. The Investment Adviser believes that favorable investment opportunities may result from consolidation of this segment. As with other utilities, however, increased regulation, increased costs and potential disruptions in supply may adversely affect investments in water supply utilities.

Utility Industries Generally. There can be no assurance that the positive developments noted above, including those relating to privatization and changing regulation, will occur or that risk factors other than those noted above will not develop in the future.

When-Issued Securities, Delayed Delivery Securities and Forward Commitments. The Fund may purchase or sell securities that it is entitled to receive on a when-issued basis. The Fund may also purchase or sell securities on a delayed delivery basis or through a forward commitment (including on a "TBA" (to be announced) basis). These transactions involve the purchase or sale of securities by the Fund at an established price with payment and delivery taking place in the future. The Fund enters into these transactions to obtain what is considered an advantageous price to the Fund at the time of entering into the transaction. TBAs also require the Fund entering into the transaction to post margin with the broker-dealer in connection with the transaction, which increases costs to the Fund.

38

There can be no assurance that a security purchased on a when-issued basis will be issued or that a security purchased or sold on a delayed delivery basis or through a forward commitment will be delivered. Also, the value of securities in these transactions on the delivery date may be more or less than the price paid by the Fund to purchase the securities. The Fund will lose money if the value of the security in such a transaction declines below the purchase price and will not benefit if the value of the security appreciates above the sale price during the commitment period.

The Fund may dispose of or renegotiate a commitment after it has been entered into, and may sell securities it has committed to purchase before those securities are delivered to the Fund on the settlement date. In these cases the Fund may realize a taxable capital gain or loss.

When the Fund engages in when-issued, TBA or forward commitment transactions, it relies on the other party to consummate the trade. Failure of such party to do so may result in the Fund's incurring a loss or missing an opportunity to obtain a price considered to be advantageous.

The market value of the securities underlying a commitment to purchase securities, and any subsequent fluctuations in their market value, is taken into account when determining the market value of the Fund starting on the day the Fund agrees to purchase the securities. The Fund does not earn interest on the securities it has committed to purchase until they are paid for and delivered on the settlement date.

Rule 18f-4 under the Investment Company Act permits a Fund to enter into when-issued or forward-settling securities (e.g., firm and standby commitments, including TBA commitments, and dollar rolls) and non-standard settlement cycle securities notwithstanding the limitation on the issuance of senior securities in Section 18 of the Investment Company Act, provided that the Fund intends to physically settle the transaction and the transaction will settle within 35 days of its trade date (the "Delayed-Settlement Securities Provision"). If a when-issued, forward-settling or non-standard settlement cycle security does not satisfy the Delayed-Settlement Securities Provision, then it is treated as a Derivatives Transaction under Rule 18f-4. See "-Regulation Regarding Derivatives" above.

Yields and Ratings. The yields on certain obligations are dependent on a variety of factors, including general market conditions, conditions in the particular market for the obligation, the financial condition of the issuer, the size of the offering, the maturity of the obligation and the ratings of the issue. The ratings of Moody's, Fitch and S&P represent their respective opinions as to the quality of the obligations they undertake to rate. Ratings, however, are general and are not absolute standards of quality. Consequently, obligations with the same rating, maturity and interest rate may have different market prices. Subsequent to its purchase by the Fund, a rated security may cease to be rated. The Fund's Investment Adviser will consider such an event in determining whether the Fund should continue to hold the security.

Zero Coupon Securities. Zero coupon securities are securities that are sold at a discount to par value and do not pay interest during the life of the security. The discount approximates the total amount of interest the security will accrue and compound over the period until maturity at a rate of interest reflecting the market rate of the security at the time of issuance. Upon maturity, the holder of a zero coupon security is entitled to receive the par value of the security.

While interest payments are not made on such securities, holders of such securities are deemed to have received income ("phantom income") annually, notwithstanding that cash may not be received currently. The effect of owning instruments that do not make current interest payments is that a fixed yield is earned not only on the original investment but also, in effect, on all discount accretion during the life of the obligations. This implicit reinvestment of earnings at a fixed rate eliminates the risk of being unable to invest distributions at a rate as high as the implicit yield on the zero coupon bond, but

39

at the same time eliminates the holder's ability to reinvest at higher rates in the future. For this reason, some of these securities may be subject to substantially greater price fluctuations during periods of changing market interest rates than are comparable securities that pay interest currently. Longer term zero coupon bonds are more exposed to interest rate risk than shorter term zero coupon bonds. These investments benefit the issuer by mitigating its need for cash to meet debt service, but also require a higher rate of return to attract investors who are willing to defer receipt of cash.

The Fund accrues income with respect to these securities for federal income tax and accounting purposes prior to the receipt of cash payments. Zero coupon securities may be subject to greater fluctuation in value and less liquidity in the event of adverse market conditions than comparably rated securities that pay cash interest at regular intervals.

Further, to maintain its qualification for pass-through treatment under the federal tax laws, the Fund is required to distribute income to its shareholders and, consequently, may have to dispose of other, more liquid portfolio securities under disadvantageous circumstances or may have to leverage itself by borrowing in order to generate the cash to satisfy these distributions. The required distributions may result in an increase in the Fund's exposure to zero coupon securities.

In addition to the above-described risks, there are certain other risks related to investing in zero coupon securities. During a period of severe market conditions, the market for such securities may become even less liquid. In addition, as these securities do not pay cash interest, the Fund's investment exposure to these securities and their risks, including credit risk, will increase during the time these securities are held in the Fund's portfolio.

Future Developments. The Board may, in the future, authorize the Fund to invest in securities contracts and investments other than those listed in this SAI and in the Prospectus, provided they are consistent with the Fund's investment objectives and do not violate any investment restrictions or policies.

General Considerations and Risks

A discussion of some of the principal risks associated with an investment in the Fund is contained in the Fund's Prospectus. An investment in the Fund should be made with an understanding that the value of the Fund's portfolio securities may fluctuate in accordance with changes in the financial condition of the issuers of the portfolio securities, the value of bonds in general, and other factors that affect the market. The order of the below risk factors does not indicate the significance of any particular risk factor.

Borrowing Risk.Borrowing may exaggerate changes in the NAV of Fund shares and in the return on the Fund's portfolio. Borrowing will cause the Fund to incur interest expense and other fees. The costs of borrowing may reduce the Fund's return. Borrowing may cause the Fund to liquidate positions when it may not be advantageous to do so to satisfy its obligations.

Custody Risk.Custody risk refers to the risks inherent in the process of clearing and settling trades and to the holding of securities, cash and other assets by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that may not be subject to independent evaluation. Local agents are held only to the standards of care of their local markets, and thus may be subject to limited or no government

40

oversight. Communications between the U.S. and emerging market countries may be unreliable, increasing the risk of delayed settlements or losses of security certificates. In general, the less developed a country's securities market is, the greater the likelihood of custody problems. Practices in relation to the settlement of securities transactions in emerging markets involve higher risks than those in developed markets, in part because of the use of brokers and counterparties that are often less well capitalized, and custody and registration of assets in some countries may be unreliable. The possibility of fraud, negligence or undue influence being exerted by the issuer or refusal to recognize ownership exists in some emerging markets, and, along with other factors, could result in ownership registration being lost. In addition, the laws of certain countries may put limits on the Fund's ability to recover its assets if a foreign bank or depository or issuer of a security or an agent of any of the foregoing goes bankrupt. The Fund would absorb any loss resulting from such custody problems and may have no successful claim for compensation.

Environmental, Social and Governance ("ESG") Integration. Although the Fund does not seek to implement a specific sustainability objective, strategy or process unless disclosed in its Prospectus, Fund management will consider ESG factors as part of the investment process for the Fund. Fund management views ESG integration as the practice of incorporating financially material ESG data or information into investment processes with the objective of enhancing risk-adjusted returns. These ESG considerations will vary depending on the Fund's particular investment strategies and may include consideration of third-party research as well as consideration of proprietary BlackRock research across the ESG risks and opportunities regarding an issuer.

The ESG characteristics utilized in the Fund's investment process are anticipated to evolve over time and one or more characteristics may not be relevant with respect to all issuers that are eligible for investment. Certain of these considerations may affect the Fund's exposure to certain companies or industries.

While Fund management views ESG considerations as having the potential to contribute to the Fund's long-term performance, there is no guarantee that such results will be achieved.

Illiquid Investments Risk.The Fund may invest up to an aggregate amount of 15% of its net assets in illiquid investments. An illiquid investment is any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without significantly changing the market value of the investment. The liquidity of an investment will be determined based on relevant market, trading and investment specific considerations as set out in the Liquidity Program as required by the Liquidity Rule (each as defined below). Illiquid investments may trade at a discount to comparable, more liquid investments and the Fund may not be able to dispose of illiquid investments in a timely fashion or at their expected prices. If illiquid investments exceed 15% of the Fund's net assets, the Liquidity Rule and the Liquidity Program will require that certain remedial actions be taken.

Issuer Insolvency Risk.The Fund's potential exposure to financially or operationally troubled issuers involves a high degree of credit and market risk, which may be heightened during an economic downturn or recession. Should an issuer of securities held by the Fund become involved in a bankruptcy proceeding, reorganization or financial restructuring, a wide variety of considerations make an evaluation of the outcome of the Fund's exposure to the issuer uncertain.

During the period of a bankruptcy proceeding, reorganization or financial restructuring, it is unlikely that the Fund will receive any interest payments on the securities of the issuer. The Fund will be subject to significant uncertainty as to whether the reorganization or restructuring will be completed, and the Fund may bear certain extraordinary expenses to protect and recover its investment. The Fund will also be subject to significant uncertainty as to when and in what manner and for what value the obligations evidenced by the securities of the issuer held by the Fund will eventually be satisfied.

41

Even if a plan of reorganization or restructuring is adopted with respect to the securities of the issuer held by the Fund, there can be no assurance that the securities or other assets received by the Fund in connection with such plan of reorganization or restructuring will not have a lower value or income potential than may have been anticipated or no value. The Fund may be unable to enforce its claims or rights in any collateral or may have its claims or security interest in any collateral challenged, disallowed or subordinated to the claims or security interests of other creditors. In addition, amendments to the U.S. Bankruptcy Code or other relevant laws could alter the expected outcome or introduce greater uncertainty regarding the outcome of the Fund's securities holdings in the issuer. In a bankruptcy proceeding, a reorganization or restructuring, the securities of the issuer held by the Fund could be re-characterizedor the Fund may receive different securities or other assets, including equity securities. These types of equity securities include, but are not limited to: common stock; preferred stock (including convertible preferred stock); bonds, notes and debentures convertible into common or preferred stock; stock purchase warrants and rights; equity interests in trusts; and depositary receipts. Equity securities are subject to changes in value, and their value may be more volatile than those of other asset classes. Holders of equity securities are subject to more risk than holders of debt securities because the status of equity holders is subordinate to debtholders in an issuer's capital structure. The value of equity securities received by the Fund could decline if the financial condition of the issuer deteriorates or if overall market and economic conditions, or conditions within the issuer's region or industry, deteriorate.

To the extent that the Fund receives other assets in connection with a bankruptcy proceeding, reorganization or financial restructuring, the Fund may also be subject to additional risks associated with the assets received. One example of assets that the Fund could receive is an interest in one or more loans made to the issuer as part of a workout agreed to by a consortium of lienholders and creditors of the issuer. The Fund may receive such interests in loans to the extent permitted by the 1940 Act.

Securities or other assets received in a reorganization or restructuring typically entail a higher degree of risk than investments in securities of issuers that have not undergone a reorganization or restructuring and may be subject to heavy selling or downward pricing pressure after completion of the reorganization or restructuring. The post-reorganization/restructuring assets and securities may also be illiquid and difficult to sell or value. If the Fund participates in negotiations with respect to a plan of reorganization or restructuring with respect to securities of the issuer held by the Fund, the Fund also may be restricted from disposing such securities for a period of time. If the Fund becomes involved in such proceedings, the Fund may have more active participation in the affairs of the issuer than that assumed generally by an investor.

Liquidity Risk Management. Rule 22e-4under the Investment Company Act (the "Liquidity Rule") requires open-endfunds, including ETFs such as the Fund, to establish a liquidity risk management program (the "Liquidity Program") and enhance disclosures regarding fund liquidity. As required by the Liquidity Rule, the Fund has implemented a Liquidity Program, and the Board, including a majority of the Independent Trustees of the Trust, has appointed BFA as the administrator of the Liquidity Program. Under the Liquidity Program, BFA assesses, manages, and periodically reviews the Fund's liquidity risk and classifies each investment held by the Fund as a "highly liquid investment," "moderately liquid investment," "less liquid investment" or "illiquid investment." The Liquidity Rule defines "liquidity risk" as the risk that the Fund could not meet requests to redeem shares issued by the Fund without significant dilution of the remaining investors' interest in the Fund. The liquidity of the Fund's portfolio investments is determined based on relevant market, trading and investment-specific considerations under the Liquidity Program. There are exclusions from certain portions of the liquidity risk management program requirements for "in-kind"ETFs, as defined in the Liquidity Rule. To the extent that an investment is deemed to be an illiquid investment or a less liquid investment, the Fund can expect to be exposed to greater liquidity risk.

42

Market Risk.The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. The value of a security or other instrument may decline due to changes in general market conditions, economic trends or events that are not specifically related to the issuer of the security or other instrument, or factors that affect a particular issuer or issuers, exchange, country, group of countries, region, market, industry, group of industries, sector or asset class. During a general market downturn, multiple asset classes may be negatively affected. Fixed-income securities with short-term maturities are generally less sensitive to such changes than are fixed-income securities with longer term maturities. (Changes in market conditions and interest rates generally do not have the same impact on all types of securities and instruments.)

Governments and regulators may take actions that affect the regulation of the Fund or the instruments in which the Fund invests, or the issuers of such instruments, in ways that are unforeseeable. Future legislation or regulation or other governmental actions could limit or preclude the Fund's abilities to achieve its investment objectives or otherwise adversely impact an investment in the Fund. Political and diplomatic events within the United States, including a contentious domestic political environment, changes in political party control of one or more branches of the U.S. government, the U.S. government's inability at times to agree on a long-term budget and deficit reduction plan, the threat of a U.S. government shutdown, and disagreements over, or threats not to increase, the U.S. government's borrowing limit (or "debt ceiling"), as well as political and diplomatic events abroad, may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. A downgrade of the ratings of U.S. government debt obligations, or concerns about the U.S. government's credit quality in general, could have a substantial negative effect on the U.S. and global economies. For example, concerns about the U.S. government's credit quality may cause increased volatility in the stock and bond markets, higher interest rates, reduced prices and liquidity of U.S. Treasury securities, and/or increased costs of various kinds of debt. Moreover, although the U.S. government has honored its credit obligations, there remains a possibility that the United States could default on its obligations. The consequences of such an unprecedented event are impossible to predict, but it is likely that a default by the United States would be highly disruptive to the U.S. and global securities markets and could significantly impair the value of the Fund's investments.

An outbreak of infectious respiratory illness caused by a novel coronavirus known as COVID-19 was first detected in China in December 2019 and has now been detected globally. This coronavirus has resulted in travel restrictions, closed international borders, enhanced health screenings at ports of entry and elsewhere, disruption of and delays in healthcare service preparation and delivery, prolonged quarantines, cancellations, supply chain disruptions, and lower consumer demand, as well as general concern and uncertainty. The impact of COVID-19, and other infectious illness outbreaks that may arise in the future, could adversely affect the economies of many nations or the entire global economy, individual issuers and capital markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illnesses in emerging market countries may be greater due to generally less established healthcare systems. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The duration of the COVID-19 outbreak and its effects cannot be determined with certainty.

Reference Rate Replacement Risk.The Fund may be exposed to financial instruments that recently transitioned from, or continue to be tied to, London Interbank Offered Rate ("LIBOR") to determine payment obligations, financing terms, hedging strategies or investment value. The United Kingdom's Financial Conduct Authority ("FCA"), which regulates LIBOR, has ceased publishing all LIBOR settings. In April 2023, however, the FCA announced that some USD LIBOR settings will continue to be published under a synthetic methodology until September 30, 2024 for certain legacy contracts. The Secured Overnight Financing Rate ("SOFR"), which is a broad measure of the cost of borrowing cash

43

overnight collateralized by U.S. Treasury securities in the repurchase agreement market, has been used increasingly on a voluntary basis in new instruments and transactions. Under U.S. regulations that implement a statutory fallback mechanism to replace LIBOR, benchmark rates based on SOFR have replaced LIBOR in different categories of financial contracts.

Neither the effect of the LIBOR transition process nor its ultimate success can yet be known. While some existing LIBOR-based instruments may contemplate a scenario where LIBOR is no longer available by providing for an alternative rate-setting methodology, there may be significant uncertainty regarding the effectiveness of any such alternative methodologies to replicate LIBOR. Not all existing LIBOR-based instruments may have alternative rate-setting provisions and there remains uncertainty regarding the willingness and ability of issuers to add alternative rate-setting provisions in certain existing instruments. Parties to contracts, securities, or other instruments using LIBOR may disagree on transition rates or the application of transition regulation, potentially resulting in uncertainty of performance and the possibility of litigation. The Fund may have instruments linked to other interbank offered rates that may also cease to be published in the future.

Risk of Derivatives.A derivative is a financial contract, the value of which depends on, or is derived from, the value of an underlying asset, such as a security, a commodity (such as gold or silver), a currency or an index (a measure of value or rates, such as the S&P 500 or the prime lending rate). Compared to securities, derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices and thus the Fund's losses may be greater if it invests in derivatives than if it invests only in conventional securities. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations. Derivatives generally involve the incurrence of leverage.

When a derivative is used as a hedge against a position that the Fund holds or is committed to purchase, any loss generated by the derivative generally should be substantially offset by gains on the hedged investment, and vice versa. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains, and in some cases, hedging can cause losses that are not offset by gains, and the Fund will recognize losses on both the investment and the hedge. Hedges are sometimes subject to imperfect matching between the derivative and the underlying security, and there can be no assurance that the Fund's hedging transactions, which entail additional transaction costs, will be effective.

Risk of Investing in Non-U.S.Debt Securities.Non-U.S.debt securities are traded on foreign exchanges and OTC in the respective countries covered by the Fund. The risks of investing in non-U.S.debt securities typically include market fluctuations caused by such factors as economic and political developments, changes in interest rates and perceived trends in bond prices. Investing in a fund whose portfolio contains securities of non-U.S.issuers involves certain risks and considerations not typically associated with investing in the securities of U.S. issuers. These risks include securities markets that may lack sufficient liquidity or may be less efficient; generally greater price volatility; less publicly available information about issuers; the imposition of withholding or other taxes; the imposition of restrictions on the expatriation of funds or other assets of the Fund; higher transaction and custody costs; delays and risks attendant in settlement procedures; difficulties in enforcing contractual obligations; lower liquidity and significantly smaller market capitalization of most non-U.S.securities markets; different accounting and disclosure standards; lower levels of regulation of the securities markets; more substantial government interference with the economy; higher rates of inflation; greater social, economic, and political uncertainty; the risk of nationalization or expropriation of assets; and different bankruptcy and insolvency regimes which may stay or prevent recovery in the event of an issuer's default.

44

Proxy Voting Policy

The Board has delegated the voting of proxies for the Fund's securities to BFA pursuant to the Fund's Proxy Voting Policy (the "Proxy Voting Policy"), and BFA has adopted policies and procedures (the "BlackRock Proxy Voting Policies") governing proxy voting by accounts managed by BFA, including the Fund.

Under the BlackRock Proxy Voting Policies, BFA will vote proxies related to Fund securities in the best interests of the Fund and its shareholders. From time to time, a vote may present a conflict between the interests of the Fund's shareholders, on the one hand, and those of BFA, or any affiliated person of the Fund or BFA, on the other. BFA maintains policies and procedures that are designed to prevent undue influence on BFA's proxy voting activity that might stem from any relationship between the issuer of a proxy (or any dissident shareholder) and BFA, BFA's affiliates, the Fund or the Fund's affiliates. Most conflicts are managed through a structural separation of BFA's Corporate Governance Group from BFA's employees with sales and client responsibilities. In addition, BFA maintains procedures to ensure that all engagements with corporate issuers or dissident shareholders are managed consistently and without regard to BFA's relationship with the issuer of the proxy or the dissident shareholder. In certain instances, BFA may determine to engage an independent fiduciary to vote proxies as a further safeguard to avoid potential conflicts of interest or as otherwise required by applicable law.

Copies of the Proxy Voting Policy, the BlackRock Global Proxy Voting Policies and the BlackRock U.S. Proxy Voting Policies are attached as Appendices A1, A2 and A3, respectively.

Information with respect to how proxies relating to the Fund's portfolio securities were voted during the 12-monthperiod ended June 30 will be available: (i) without charge, upon request, by calling 1-800-474-2737or through the Fund's website at www.blackrock.com; and (ii) on the SEC's website at www.sec.gov.

Portfolio Holdings Information

On each Business Day (as defined in the Creation and Redemption of Creation Unitssection of this SAI), prior to the opening of regular trading on the Fund's primary listing exchange, the Fund discloses on its website (www.blackrock.com) certain information relating to the portfolio holdings that will form the basis of the Fund's next net asset value per share calculation.

In addition, certain information may also be made available to certain parties:

45

BFA employees may also discuss portfolio holdings-related information with broker/dealers, in connection with settling the Fund's transactions, as may be necessary to conduct business in the ordinary course in a manner consistent with the disclosure in the Fund's current registration statements.

The Trust's Chief Compliance Officer or his delegate may authorize disclosure of portfolio holdings information pursuant to the above policy and procedures, subject to restrictions on selective disclosure imposed by applicable law. The Board reviews the policy and procedures for disclosure of portfolio holdings information at least annually.

Investment Policies

The Board has adopted as fundamental policies the following numbered investment policies, which cannot be changed without the approval of the holders of a majority of the applicable Fund's outstanding voting securities. A vote of a majority of the outstanding voting securities of the Fund is defined in the Investment Company Act as the lesser of (i) 67% or more of the voting securities present at a shareholder meeting, if the holders of more than 50% of the outstanding voting securities of the Fund are present or represented by proxy, or (ii) more than 50% of the outstanding voting securities of the Fund. The Fund has also adopted certain non-fundamentalinvestment policies, including its investment objectives. Non-fundamentalinvestment policies may be changed by the Board without shareholder approval. Therefore, the Fund may change its investment objective(s) without shareholder approval.

46

Fundamental Investment Policies

The Fund may not:

Notations Regarding the Fund's Fundamental Investment Policies

The following notations are not considered to be part of the Fund's fundamental investment policies and are subject to change without shareholder approval.

With respect to the fundamental policy relating to concentration set forth in (1) above, the Investment Company Act does not define what constitutes "concentration" in an industry. The SEC staff has taken the position that investment of 25% or more of a fund's total assets in one or more issuers conducting their principal activities in the same industry or group of industries constitutes concentration. It is possible that interpretations of concentration could change in the future. The policy in (1) above will be interpreted to refer to concentration as that term may be interpreted from time to time. The policy also will be interpreted to permit investment without limit in the following: securities of the U.S. government and its agencies or instrumentalities; securities of state, territory, possession or municipal governments and their authorities, agencies, instrumentalities or political subdivisions; and repurchase agreements collateralized by any such obligations. Accordingly, issuers of the foregoing securities will not be considered to be members of any industry. There also will be no limit on investment in issuers domiciled in a single jurisdiction or country. Finance companies will be considered to be in the industries of their parents if their activities are primarily related to financing the activities of the parents. Each foreign government will be considered to be a member of a separate industry. With respect to the Fund's industry classifications, the Fund currently utilizes any one or more of the industry sub-classificationsused by one or more widely recognized market indexes or rating group indexes, and/or as defined by Fund management. The policy also will be interpreted to give broad authority to the Fund as to how to classify issuers within or among industries.

With respect to the fundamental policy relating to borrowing money set forth in (2) above, the Investment Company Act permits the Fund to borrow money in amounts of up to one-third of the Fund's total assets from banks for any purpose, and to borrow up to 5% of the Fund's total assets from banks or other lenders for temporary purposes. (The Fund's total assets include the amounts being borrowed.) To limit the risks attendant to borrowing, the Investment Company Act requires the Fund to maintain at all times an "asset coverage" of at least 300% of the amount of its borrowings. Asset coverage means the ratio that the value of the Fund's total assets (including amounts borrowed),

47

minus liabilities other than borrowings, bears to the aggregate amount of all borrowings. Borrowing money to increase portfolio holdings is known as "leveraging." Certain trading practices and investments, such as reverse repurchase agreements, may be considered to be borrowings or involve leverage and thus are subject to the Investment Company Act restrictions. In accordance with Rule 18f-4 under the Investment Company Act, when the Fund engages in reverse repurchase agreements and similar financing transactions, the Fund may either (i) maintain asset coverage of at least 300% with respect to such transactions and any other borrowings in the aggregate, or (ii) treat such transactions as "derivatives transactions" and comply with Rule 18f-4 with respect to such transactions. Short-term credits necessary for the settlement of securities transactions and arrangements with respect to securities lending will not be considered to be borrowings under the policy. Practices and investments that may involve leverage but are not considered to be borrowings are not subject to the policy.

With respect to the fundamental policy relating to underwriting set forth in (5) above, the Investment Company Act does not prohibit the Fund from engaging in the underwriting business or from underwriting the securities of other issuers; in fact, in the case of diversified funds, the Investment Company Act permits the Fund to have underwriting commitments of up to 25% of its assets under certain circumstances. Those circumstances currently are that the amount of the Fund's underwriting commitments, when added to the value of the Fund's investments in issuers where the Fund owns more than 10% of the outstanding voting securities of those issuers, cannot exceed the 25% cap. A fund engaging in transactions involving the acquisition or disposition of portfolio securities may be considered to be an underwriter under the 1933 Act. Although it is not believed that the application of the 1933 Act provisions described above would cause the Fund to be engaged in the business of underwriting, the policy in (5) above will be interpreted not to prevent the Fund from engaging in transactions involving the acquisition or disposition of portfolio securities, regardless of whether the Fund may be considered to be an underwriter under the 1933 Act or is otherwise engaged in the underwriting business to the extent permitted by applicable law.

With respect to the fundamental policy relating to lending set forth in (7) above, the Investment Company Act does not prohibit the Fund from making loans (including lending its securities); however, SEC staff interpretations currently prohibit funds from lending more than one-thirdof their total assets (including lending its securities), except through the purchase of debt obligations or the use of repurchase agreements. In addition, collateral arrangements with respect to options, forward currency and futures transactions and other derivative instruments (as applicable), as well as delays in the settlement of securities transactions, will not be considered loans.

Non-FundamentalInvestment Policies

Under its non-fundamentalinvestment restrictions, which may be changed by the Board without shareholder approval, the Fund may not:

Unless otherwise indicated, all limitations under the Fund's fundamental or non-fundamentalinvestment policies apply only at the time that a transaction is undertaken. Any change in the

48

percentage of the Fund's assets invested in certain securities or other instruments resulting from market fluctuations or other changes in the Fund's total assets will not require the Fund to dispose of an investment until BFA determines that it is practicable to sell or close out the investment without undue market or tax consequences.

Continuous Offering

The method by which Creation Units are created and traded may raise certain issues under applicable securities laws. Because new Creation Units are issued and sold by the Fund on an ongoing basis, at any point a "distribution," as such term is used in the 1933 Act, may occur. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject them to the prospectus delivery requirement and liability provisions of the 1933 Act.

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing an order with the Distributor, breaks them down into constituent shares and sells such shares directly to customers or if it chooses to couple the creation of new shares with an active selling effort involving solicitation of secondary market demand for shares. A determination of whether one is an underwriter for purposes of the 1933 Act must take into account all of the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case and the examples mentioned above should not be considered a complete description of all the activities that could lead to a categorization as an underwriter.

Broker-dealer firms should also note that dealers who are not "underwriters" but are effecting transactions in shares, whether or not participating in the distribution of shares, generally are required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(a)(3) of the 1933 Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. Firms that incur a prospectus delivery obligation with respect to shares of the Fund are reminded that, pursuant to Rule 153 under the 1933 Act, a prospectus delivery obligation under Section 5(b)(2) of the 1933 Act owed to an exchange member in connection with a sale on the Listing Exchange generally is satisfied by the fact that the prospectus is available at the Listing Exchange upon request. The prospectus delivery mechanism provided in Rule 153 is available only with respect to transactions on an exchange.

Management

Trustees and Officers. The Board of Trustees (the "Board") of the Trust consists of eleven individuals (each a "Trustee"), eight of whom are not "interested persons" of the Trust as defined in the Investment Company Act (the "Independent Trustees"). The registered investment companies advised by the Manager or its affiliates (the "BlackRock-advised Funds") are organized into the BlackRock Multi-Asset Complex, the BlackRock Fixed-Income Complex, and the iShares Complex (each, a "BlackRock Fund Complex"). The Trust is included in the BlackRock Fund Complex referred to as the BlackRock Fixed-Income Complex. The Trustees also oversee as board members the operations of the other open-endand closed-endregistered investment companies included in the BlackRock Fixed-Income Complex.

The Board has overall responsibility for the oversight of the Trust and the Fund. The Chair of the Board and the Chief Executive Officer are different people. Not only is the Chair of the Board an Independent Trustee, but also the Chair of each Board committee (each, a "Committee") is an Independent Trustee. The Board has five standing Committees: an Audit Committee, a Governance and Nominating Committee, a Compliance Committee, a Performance Oversight Committee and an Executive Committee. The role of the Chair of the Board is to preside over all meetings of the Board and to act as a liaison with service providers, officers, attorneys, and other Trustees between meetings. The Chair of each Committee performs a similar role with respect to the Committee. The Chair of the Board or a Committee may also perform such other functions as may be delegated by the Board or the Committee from time to time. The Independent Trustees meet regularly outside the presence of the Fund's management, in executive sessions or with other service providers to the Fund. The Board has regular meetings five times a year, including a meeting to consider the approval of the Fund's investment management agreement, and, if necessary, may hold special meetings before its next regular meeting. Each Committee meets regularly to conduct the oversight functions delegated to that Committee by the Board and reports its findings to the Board. The Board and each standing Committee conduct annual assessments of their oversight function and structure. The Board has determined that the Board's leadership structure is appropriate because it allows the Board to exercise independent judgment over management and to allocate areas of responsibility among Committees and the Board to enhance oversight.

The Board decided to separate the roles of Chief Executive Officer from the Chair because it believes that having independent Chair:

The Board has engaged the Manager to manage the Fund on a day-to-daybasis. The Board is responsible for overseeing the Manager, other service providers, the operations of the Fund and associated risks in accordance with the provisions of the Investment Company Act, state law, other applicable laws, the Fund's charter, and the Fund's investment objective(s) and strategies. The Board reviews, on an ongoing basis, the Fund's performance, operations, and investment strategies and techniques. The Board also conducts reviews of the Manager and its role in running the operations of the Fund.

Day-to-dayrisk management with respect to the Fund is the responsibility of the Manager, sub-advisersor other service providers (depending on the nature of the risk), subject to the supervision of the Manager. The Fund is subject to a number of risks, including investment, compliance, operational and valuation risks, among others. While there are a number of risk management functions performed by the Manager, sub-advisersor other service providers, as applicable, it is not possible to eliminate all of the risks applicable to the Fund. Risk oversight is part of the Board's general oversight of the Fund and is addressed as part of various Board and Committee activities. The Board, directly or through Committees, also reviews reports from, among others, management, the independent registered public accounting firm for the Fund, the Manager, sub-advisersand internal auditors for the Manager or its affiliates, as appropriate, regarding risks faced by the Fund and management's or the service provider's risk functions. The Committee system facilitates the timely and efficient

50

consideration of matters by the Trustees and facilitates effective oversight of compliance with legal and regulatory requirements and of the Fund's activities and associated risks. The Board has approved the appointment of a Chief Compliance Officer ("CCO"), who oversees the implementation and testing of the Fund's compliance program and reports regularly to the Board regarding compliance matters for the Fund and their service providers. The Independent Trustees have engaged independent legal counsel to assist them in performing their oversight responsibilities.

Audit Committee. The Board has a standing Audit Committee composed of Catherine A. Lynch (Chair), Frank J. Fabozzi, Lorenzo A. Flores and J. Phillip Holloman, all of whom are Independent Trustees. The principal responsibilities of the Audit Committee are to assist the Board in fulfilling its oversight responsibilities relating to the accounting and financial reporting policies and practices of the Fund. The Audit Committee's responsibilities include, without limitation: (i) approving, and recommending to the full Board for approval, the selection, retention, termination and compensation of the Fund's independent registered public accounting firm (the "Independent Registered Public Accounting Firm") and evaluating the independence and objectivity of the Independent Registered Public Accounting Firm; (ii) approving all audit engagement terms and fees for the Fund; (iii) reviewing the conduct and results of each audit; (iv) reviewing any issues raised by the Fund's Independent Registered Public Accounting Firm or management regarding the accounting or financial reporting policies and practices of the Fund, its internal controls, and, as appropriate, the internal controls of certain service providers and management's response to any such issues; (v) reviewing and discussing the Fund's audited and unaudited financial statements and disclosure in the Fund's shareholder reports relating to the Fund's performance; (vi) assisting the Board's responsibilities with respect to the internal controls of the Fund and its service providers with respect to accounting and financial matters; and (vii) resolving any disagreements between the Fund's management and the Fund's Independent Registered Public Accounting Firm regarding financial reporting. The Board has adopted a written charter for the Board's Audit Committee. During the fiscal year ended July 31, 2023, the Audit Committee met nine times.

Governance and Nominating Committee. The Board has a standing Governance and Nominating Committee composed of W. Carl Kester (Chair), Cynthia L. Egan, J. Phillip Holloman, R. Glenn Hubbard and Catherine A. Lynch, all of whom are Independent Trustees. The principal responsibilities of the Governance and Nominating Committee are: (i) identifying individuals qualified to serve as Independent Trustees and recommending Board nominees that are not "interested persons" of the Fund (as defined in the Investment Company Act) for election by shareholders or appointment by the Board; (ii) advising the Board with respect to Board composition, procedures and Committees of the Board (other than the Audit Committee); (iii) overseeing periodic self-assessments of the Board and Committees of the Board (other than the Audit Committee); (iv) reviewing and making recommendations in respect to Independent Trustee compensation; (v) monitoring corporate governance matters and making recommendations in respect thereof to the Board; (vi) acting as the administrative committee with respect to Board policies and procedures, committee policies and procedures (other than the Audit Committee) and codes of ethics as they relate to the Independent Trustees; and (vii) reviewing and making recommendations to the Board in respect of Fund share ownership by the Independent Trustees. The Board has adopted a written charter for the Board's Governance and Nominating Committee. During the fiscal year ended July 31, 2023, the Governance and Nominating Committee met six times.

The Governance and Nominating Committee of the Board seeks to identify individuals to serve on the Board who have a diverse range of viewpoints, qualifications, experiences, backgrounds and skill sets so that the Board will be better suited to fulfill its responsibility of overseeing the Fund's activities. In so doing, the Governance and Nominating Committee reviews the size of the Board, the ages of the current Trustees and their tenure on the Board, and the skills, background and experiences of the Trustees in light of the issues facing the Fund in determining whether one or more new trustees should be added to the Board. The Board as a group strives to achieve diversity in terms of gender, race and

51

geographic location. The Governance and Nominating Committee believes that the Trustees as a group possess the array of skills, experiences and backgrounds necessary to guide the Fund. The Trustees' biographies included herein highlight the diversity and breadth of skills, qualifications and expertise that the Trustees bring to the Fund.

The Governance and Nominating Committee may consider nominations for Trustees made by the Fund's shareholders as it deems appropriate. Under the Trust's Bylaws, shareholders must follow certain procedures to nominate a person for election as a Trustee at a shareholder meeting at which Trustees are to be elected. Under these advance notice procedures, shareholders must submit the proposed nominee by delivering a notice to the Secretary of the Fund at its principal executive offices no earlier than the 150^th day prior to such meeting and not later than 5:00 p.m., Eastern Time, on the later of the 120^th day prior to such meeting or the tenth day following the day on which public announcement is first made of the date of such meeting.

The Trust's Bylaws provide that notice of a proposed nomination must include certain information about the shareholder and the nominee, as well as certain other information, including a written consent of the proposed nominee to serve if elected. Reference is made to the Trust's Bylaws for more details.

Compliance Committee. The Board has a Compliance Committee composed of Cynthia L. Egan (Chair), Stayce D. Harris, R. Glenn Hubbard and W. Carl Kester, all of whom are Independent Trustees. The Compliance Committee's purpose is to assist the Board in fulfilling its responsibility with respect to the oversight of regulatory and fiduciary compliance matters involving the Fund, the fund-related activities of BlackRock, and any sub-advisersand the Fund's other third party service providers. The Compliance Committee's responsibilities include, without limitation: (i) overseeing the compliance policies and procedures of the Fund and its service providers and recommending changes or additions to such policies and procedures; (ii) reviewing information on and, where appropriate, recommending policies concerning the Fund's compliance with applicable law; (iii) reviewing information on any significant correspondence with or other actions by regulators or governmental agencies with respect to the Fund and any employee complaints or published reports that raise concerns regarding compliance matters; and (iv) reviewing reports from, overseeing the annual performance review of, and making certain recommendations in respect of, the Fund's CCO, including, without limitation, determining the amount and structure of the CCO's compensation. The Board has adopted a written charter for the Board's Compliance Committee. During the fiscal year ended July 31, 2023, the Compliance Committee met four times.

Performance Oversight Committee. The Board has a Performance Oversight Committee composed of Frank J. Fabozzi (Chair), Cynthia L. Egan, Lorenzo A. Flores, Stayce D. Harris, J. Phillip Holloman, R. Glenn Hubbard, W. Carl Kester and Catherine A. Lynch, all of whom are Independent Trustees. The Performance Oversight Committee's purpose is to assist the Board in fulfilling its responsibility to oversee the Fund's investment performance relative to the Fund's investment objective(s), policies and practices. The Performance Oversight Committee's responsibilities include, without limitation: (i) reviewing the Fund's investment objectives, policies and practices; (ii) recommending to the Board any required action in respect of changes in fundamental and non-fundamentalinvestment restrictions; (iii) reviewing information on appropriate benchmarks and competitive universes; (iv) reviewing the Fund's investment performance relative to such benchmarks; (v) reviewing information on unusual or exceptional investment matters; (vi) reviewing whether the Fund has complied with its investment policies and restrictions; and (vii) overseeing policies, procedures and controls regarding valuation of the Fund's investments. The Board has adopted a written charter for the Board's Performance Oversight Committee. During the fiscal year ended July 31, 2023, the Performance Oversight Committee met four times.

52

Executive Committee. The Board has an Executive Committee composed of R. Glenn Hubbard (Chair) W. Carl Kester, both of whom are Independent Trustees, and John M. Perlowski, who serves as an interested Trustee. The principal responsibilities of the Executive Committee include, without limitation: (i) acting on routine matters between meetings of the Board; (ii) acting on such matters as may require urgent action between meetings of the Board; and (iii) exercising such other authority as may from time to time be delegated to the Executive Committee by the Board. The Board has adopted a written charter for the Board's Executive Committee. During the fiscal year ended July 31, 2023, the Executive Committee did not meet.

The Independent Trustees have adopted a statement of policy that describes the experiences, qualifications, skills and attributes that are necessary and desirable for potential Independent Trustee candidates (the "Statement of Policy"). The Board believes that each Independent Trustee satisfied, at the time he or she was initially elected or appointed a Trustee, and continues to satisfy, the standards contemplated by the Statement of Policy as well as the standards set forth in the Trust's Bylaws. Furthermore, in determining that a particular Trustee was and continues to be qualified to serve as a Trustee, the Board has considered a variety of criteria, none of which, in isolation, was controlling. The Board believes that, collectively, the Trustees have balanced and diverse experiences, skills, attributes and qualifications, which will allow the Board to operate effectively in governing the Fund and protecting the interests of shareholders. Among the attributes common to all Trustees is their ability to review critically, evaluate, question and discuss information provided to them, to interact effectively with the Manager, sub-advisers,other service providers, counsel and independent auditors, and to exercise effective business judgment in the performance of their duties as Trustees. Each Trustee's ability to perform his or her duties effectively is evidenced by his or her educational background or professional training; business, consulting, public service or academic positions; experience from service as a board member of the Trust or the other funds in the BlackRock Fund Complexes (and any predecessor funds), other investment funds, public companies, or not-for-profitentities or other organizations; ongoing commitment and participation in Board and Committee meetings, as well as his or her leadership of standing and other committees throughout the years; or other relevant life experiences.

The table below discusses some of the experiences, qualifications and skills of each Trustee that support the conclusion that he or she should serve on the Board.

Share Ownership

Information relating to each Trustee's share ownership in all BlackRock-advised Funds that are currently overseen by the respective Trustee ("Supervised Funds") as of December 31, 2022 is set forth in the chart below. Amounts shown may include shares as to which a Trustee has indirect beneficial ownership, such as through participation in certain family accounts, 529 college savings plan interests, or similar arrangements where the Trustee has beneficial economic interest but not a direct ownership interest.

As of November 3, 2023, the Trustees and officers of the Trust as a group directly or indirectly beneficially owned an aggregate of less than 1% of the outstanding shares of the Fund. As of December 31, 2022, none of the Independent Trustees of the Trust or their immediate family members owned beneficially or of record any securities of the Fund's investment adviser, principal underwriter, or any person directly or indirectly controlling, controlled by or under common control with such entities.

Compensation of Trustees

Each Independent Trustee and non-management Interested Trustee is paid an annual retainer of $370,000 per year for his or her services as a Board member of the BlackRock-advised Funds, including the Fund, together with out-of-pocketexpenses in accordance with a Board policy on travel and other business expenses relating to attendance at meetings. In addition, the Chair of the Board and the Vice Chair of the Board are paid an additional annual retainer of $100,000 and $60,000 respectively. The Chairs of the Audit Committee, Performance Oversight Committee, Compliance Committee, and Governance and Nominating Committee are paid an additional annual retainer of $45,000, $37,500, $45,000 and $37,500, respectively. Each of the members of the Audit Committee Compliance Committee, and Governance and Nominating Committee are paid an additional annual retainer of $30,000, $25,000 and $25,000, respectively, for his or her service on such committee. The Fund will pay a pro rataportion quarterly (based on relative net assets) of the foregoing Trustee fees paid by the funds in the BlackRock Fixed-Income Complex.

63

The Independent Trustees have agreed that a maximum of 50% of each Independent Trustee's total compensation paid by funds in the BlackRock Fixed-Income Complex may be deferred pursuant to the BlackRock Fixed-Income Complex's deferred compensation plan. Under the deferred compensation plan, deferred amounts earn a return for the Independent Trustees as though equivalent dollar amounts had been invested in shares of certain funds in the BlackRock Fixed-Income Complex selected by the Independent Trustees. This has approximately the same economic effect for the Independent Trustees as if they had invested the deferred amounts in such funds in the BlackRock Fixed-Income Complex. The deferred compensation plan is not funded and obligations thereunder represent general unsecured claims against the general assets of a fund and are recorded as a liability for accounting purposes.

The following table sets forth the compensation the Trust paid the Trustees, on behalf of the Fund, for the fiscal year ending July 31, 2023, and the aggregate compensation, including deferred compensation amounts, paid to them by all BlackRock-advised Funds for the calendar year ended December 31, 2022.

Control Persons and Principal Holders of Securities. As of November 3, 2023, the Trustees and officers of the Trust as a group owned an aggregate of less than 1% of the outstanding shares of the Funds. Although the Trust does not have information concerning the beneficial ownership of shares held in the names of Depository Trust Company ("DTC") Participants (as defined below), as of October 31, 2023, the name and percentage ownership of each DTC Participant that owned of record 5% or more of the outstanding shares of the Fund were as follows:

Potential Conflicts of Interest.Certain activities of BFA, BlackRock, Inc. and the other subsidiaries of BlackRock, Inc. (collectively referred to in this section as "BlackRock") and their respective directors, officers and employees, with respect to the Fund and/or other accounts managed by BlackRock, may give rise to actual or perceived conflicts of interest such as those described below.

BlackRock is one of the world's largest asset management firms. BlackRock, its subsidiaries and their respective directors, officers and employees, including the business units or entities and personnel who may be involved in the investment activities and business operations of the Fund, are engaged worldwide in businesses, including managing equities, fixed- income securities, cash and alternative investments, and have interests other than that of managing the Fund. These are considerations of which investors in the Fund should be aware, and which may cause conflicts of interest that could disadvantage the Fund and its shareholders. These businesses and interests include potential multiple advisory, financial and other relationships with, or interests in, companies and interests in securities or other instruments that may be purchased or sold by the Fund.

BlackRock has proprietary interests in, and may manage or advise with respect to, accounts or funds (including separate accounts and other funds and collective investment vehicles) that have investment objectives similar to those of the Fund and/or that engage in transactions in the same types of securities, currencies and instruments as the Fund. BlackRock is also a major participant in the global currency, equities, swap and fixed income markets, in each case, for the accounts of clients and, in some cases, on a proprietary basis. As such, BlackRock is or may be actively engaged in transactions in the same securities, currencies, and instruments in which the Fund invests. Such activities could affect the prices and availability of the securities, currencies, and instruments in which the Fund invests, which could have an adverse impact on the Fund's performance. Such transactions, particularly in respect of most proprietary accounts or client accounts, will be executed independently of the Fund's transactions and thus at prices or rates that may be more or less favorable than those obtained by the Fund.

65

When BlackRock seeks to purchase or sell the same assets for accounts, including the Fund, the assets actually purchased or sold may be allocated among the accounts on a basis determined in its good faith discretion to be equitable. In some cases, this system may adversely affect the size or price of the managed assets purchased or sold for the Fund. In addition, transactions in investments by one or more other accounts managed by BlackRock may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund, particularly, but not limited to, with respect to small-capitalization, emerging market or less liquid strategies. This may occur with respect to BlackRock-advised accounts when investment decisions regarding the Fund are based on research or other information that is also used to support decisions for other accounts. When BlackRock implements a portfolio decision or strategy on behalf of another account ahead of, or contemporaneously with, similar decisions or strategies for the Fund, market impact, liquidity constraints, or other factors could result in the Fund receiving less favorable trading results and the costs of implementing such decisions or strategies could be increased or the Fund could otherwise be disadvantaged. BlackRock may, in certain cases, elect to implement internal policies and procedures designed to limit such consequences, which may cause the Fund to be unable to engage in certain activities, including purchasing or disposing of securities, when it might otherwise be desirable for it to do so.

Conflicts may also arise because portfolio decisions regarding the Fund may benefit other accounts managed by BlackRock. For example, the sale of a long position or establishment of a short position by the Fund may impair the price of the same security sold short by (and therefore benefit) BlackRock or its other accounts or funds, and the purchase of a security or covering of a short position in a security by the Fund may increase the price of the same security held by (and therefore benefit) BlackRock or its other accounts or funds.

In addition, to the extent permitted by applicable law, the Fund may invest its assets in other funds advised by BlackRock, including funds that are managed by one or more of the same portfolio managers, which could result in conflicts of interest relating to asset allocation, timing of Fund purchases and sales, and increased remuneration and profitability for BlackRock and/or its personnel, including portfolio managers.

In certain circumstances, BlackRock, on behalf of the Fund, may seek to buy from or sell securities to another fund or account advised by BlackRock. BlackRock may (but is not required to) effect purchases and sales between BlackRock clients ("cross trades"), including the Fund, if BlackRock believes such transactions are appropriate based on each party's investment objectives and guidelines, subject to applicable law and regulation. There may be potential conflicts of interest or regulatory issues relating to these transactions which could limit BlackRock's decision to engage in these transactions for the Fund. BlackRock may have a potentially conflicting division of loyalties and responsibilities to the parties in such transactions. On any occasion when the Fund participates in a cross trade, BlackRock will comply with procedures adopted under applicable rules and SEC guidance.

BlackRock and its clients may pursue or enforce rights with respect to an issuer in which the Fund has invested, and those activities may have an adverse effect on the Fund. As a result, prices, availability, liquidity and terms of the Fund's investments may be negatively impacted by the activities of BlackRock or its clients, and transactions for the Fund may be impaired or effected at prices or terms that may be less favorable than would otherwise have been the case.

The results of the Fund's investment activities may differ significantly from the results achieved by BlackRock for its proprietary accounts or other accounts (including investment companies or collective investment vehicles) which it manages or advises. It is possible that one or more accounts managed or advised by BlackRock and such other accounts will achieve investment results that are substantially more or less favorable than the results achieved by the Fund. Moreover, it is possible that the Fund will

66

sustain losses during periods in which one or more proprietary or other accounts managed or advised by BlackRock achieve significant profits. The opposite result is also possible.

From time to time, the Fund may be restricted from purchasing or selling securities, or from engaging in other investment activities because of regulatory, legal or contractual requirements applicable to BlackRock or other accounts managed or advised by BlackRock, and/or the internal policies of BlackRock designed to comply with such requirements. As a result, there may be periods, for example, when BlackRock will not initiate or recommend certain types of transactions in certain securities or instruments with respect to which BlackRock is performing services or when position limits have been reached. For example, the investment activities of BlackRock for its proprietary accounts and accounts under its management may limit the investment opportunities for the Fund in certain emerging and other markets in which limitations are imposed upon the amount of investment, in the aggregate or in individual issuers, by affiliated foreign investors.

In connection with its management of the Fund, BlackRock may have access to certain fundamental analysis and proprietary technical models developed by BlackRock. BlackRock will not be under any obligation, however, to effect transactions on behalf of the Fund in accordance with such analysis and models. In addition, BlackRock will not have any obligation to make available any information regarding its proprietary activities or strategies, or the activities or strategies used for other accounts managed by them, for the benefit of the management of the Fund and it is not anticipated that BlackRock will have access to such information for the purpose of managing the Fund. The proprietary activities or portfolio strategies of BlackRock, or the activities or strategies used for accounts managed by BlackRock or other client accounts could conflict with the transactions and strategies employed by BlackRock in managing the Fund.

The Fund may be included in investment models developed by BlackRock for use by clients and financial advisors. To the extent clients invest in these investment models and increase the assets under management of the Fund, the investment management fee amounts paid by the Fund to BlackRock may also increase. The price, availability and liquidity of the Fund may be impacted by purchases and sales of the Fund by model-driven investment portfolios, as well as by BlackRock itself and by its advisory clients.

In addition, certain principals and certain employees of the Fund's investment adviser are also principals or employees of other business units or entities within BlackRock. As a result, these principals and employees may have obligations to such other business units or entities or their clients and such obligations to other business units or entities or their clients may be a consideration of which investors in the Fund should be aware.

BlackRock may enter into transactions and invest in securities, instruments and currencies on behalf of the Fund in which clients of BlackRock or, to the extent permitted by the SEC and applicable law, BlackRock serves as the counterparty, principal or issuer. In such cases, such party's interests in the transaction will be adverse to the interests of the Fund, and such party may have no incentive to assure that the Fund obtains the best possible prices or terms in connection with the transactions. In addition, the purchase, holding and sale of such investments by the Fund may enhance the profitability of BlackRock.

BlackRock may also create, write or issue derivatives for clients based on the underlying securities, currencies or instruments in which the Fund may invest or on the performance of the Fund. An entity in which BlackRock has a significant minority interest will create, write or issue options which may be based on the performance of certain Funds. BlackRock has the right to receive a portion of the gross revenue earned by such entity. Options writing by such entity on the Fund could potentially lead to increased purchase activity with respect to the Fund and increased assets under management for BlackRock.

67

BlackRock has entered into an arrangement with Markit Indices Limited, the index provider for underlying fixed-income indexes used by certain iShares funds, related to derivative fixed-income products that are based on such iShares funds. BlackRock may receive certain payments for licensing intellectual property belonging to BlackRock and for facilitating the provision of data in connection with such derivative products, which may include payments based on the trading volumes of, or revenues generated by, the derivative products. However, BlackRock will not receive any such payments on those derivative products utilized by the Fund or other BlackRock funds or accounts. Other funds and accounts managed by BlackRock may from time to time transact in such derivative products, which could contribute to the viability or success of such derivative products by making them more appealing to funds and accounts managed by third parties, and in turn lead to increased payments to BlackRock. Trading activity in such derivative products could also potentially lead to increased purchase activity with respect to these iShares ETFs and increased assets under management for BlackRock.

The Fund may, subject to applicable law, purchase investments that are the subject of an underwriting or other distribution by BlackRock and may also enter into transactions with other clients of BlackRock where such other clients have interests adverse to those of the Fund.

At times, these activities may cause business units or entities within BlackRock to give advice to clients that may cause these clients to take actions adverse to the interests of the Fund. To the extent such transactions are permitted, the Fund will deal with BlackRock on an arm's-lengthbasis.

To the extent authorized by applicable law, BlackRock may act as broker, dealer, agent, lender or adviser or in other commercial capacities for the Fund. It is anticipated that the commissions, mark-ups,mark-downs, financial advisory fees, underwriting and placement fees, sales fees, financing and commitment fees, brokerage fees, other fees, compensation or profits, rates, terms and conditions charged by BlackRock will be in its view commercially reasonable, although BlackRock, including its sales personnel, will have an interest in obtaining fees and other amounts that are favorable to BlackRock and such sales personnel, which may have an adverse effect on the Fund. Index based funds may use an index provider that is affiliated with another service provider of the Fund or BlackRock that acts as a broker, dealer, agent, lender or in other commercial capacities for the Fund or BlackRock.

Subject to applicable law, BlackRock (and its personnel and other distributors) will be entitled to retain fees and other amounts that they receive in connection with their service to the Fund as broker, dealer, agent, lender, adviser or in other commercial capacities. No accounting to the Fund or their shareholders will be required, and no fees or other compensation payable by the Fund or their shareholders will be reduced by reason of receipt by BlackRock of any such fees or other amounts.

When BlackRock acts as broker, dealer, agent, adviser or in other commercial capacities in relation to the Fund, BlackRock may take commercial steps in its own interests, which may have an adverse effect on the Fund. The Fund will be required to establish business relationships with its counterparties based on the Fund's own credit standing. BlackRock will not have any obligation to allow its credit to be used in connection with the Fund's establishment of its business relationships, nor is it expected that the Fund's counterparties will rely on the credit of BlackRock in evaluating the Fund's creditworthiness.

BTC, an affiliate of BlackRock, pursuant to SEC exemptive relief, acts as securities lending agent to, and receives a share of securities lending revenues from, the Fund. BlackRock will also receive compensation for managing the reinvestment of the cash collateral from securities lending. There are potential conflicts of interests in managing a securities lending program, including but not limited to: (i) BlackRock as securities lending agent may have an incentive to increase or decrease the amount of securities on loan or to lend particular securities in order to generate additional risk-adjusted revenue for BlackRock and its affiliates; and (ii) BlackRock as securities lending agent may have an incentive to

68

allocate loans to clients that would provide more revenue to BlackRock. As described further below, BlackRock seeks to mitigate this conflict by providing its securities lending clients with equal lending opportunities over time in order to approximate pro rata _allocation.

As part of its securities lending program, BlackRock indemnifies the Fund and certain other clients and/or funds against a shortfall in collateral in the event of borrower default. On a regular basis, BlackRock calculates the potential dollar exposure of collateral shortfall resulting from a borrower default ("shortfall risk") in the securities lending program. BlackRock establishes program-wide borrower limits ("credit limits") to actively manage borrower-specific credit exposure. BlackRock oversees the risk model that calculates projected collateral shortfall values using loan-level factors such as loan and collateral type and market value as well as specific borrower credit characteristics. When necessary, BlackRock may adjust securities lending program attributes by restricting eligible collateral or reducing borrower credit limits. As a result, the management of program-wide exposure as well as BlackRock-specific indemnification exposure may affect the amount of securities lending activity BlackRock may conduct at any given point in time by reducing the volume of lending opportunities for certain loans (including by asset type, collateral type and/or revenue profile).

BlackRock uses a predetermined systematic process in order to approximate pro rataallocation over time. In order to allocate a loan to a portfolio: (i) BlackRock as a whole must have sufficient lending capacity pursuant to the various program limits (i.e., indemnification exposure limit and counterparty borrower limits); (ii) the lending portfolio must hold the asset at the time a loan opportunity arrives; and (iii) the lending portfolio must also have enough inventory, either on its own or when aggregated with other portfolios into one single market delivery, to satisfy the loan request. In doing so, BlackRock seeks to provide equal lending opportunities for all portfolios, independent of whether BlackRock indemnifies the portfolio. Equal opportunities for lending portfolios does not guarantee equal outcomes. Specifically, short and long-term outcomes for individual clients may vary due to asset mix, asset/liability spreads on different securities, and the overall limits imposed by the firm.

BlackRock may decline to make a securities loan on behalf of the Fund, discontinue lending on behalf of the Fund or terminate a securities loan on behalf of the Fund for any reason, including but not limited to regulatory requirements and/or market rules, liquidity considerations, or credit considerations, which may impact the Fund by reducing or eliminating the volume of lending opportunities for certain types of loans, loans in particular markets, loans of particular securities or types of securities, or for loans overall.

Purchases and sales of securities and other assets for the Fund may be bunched or aggregated with orders for other BlackRock client accounts, including with accounts that pay different transaction costs solely due to the fact that they have different research payment arrangements. BlackRock, however, is not required to bunch or aggregate orders if portfolio management decisions for different accounts are made separately, or if they determine that bunching or aggregating is not practicable or required, or in cases involving client direction.

Prevailing trading activity frequently may make impossible the receipt of the same price or execution on the entire volume of securities purchased or sold. When this occurs, the various prices may be averaged, and the Fund will be charged or credited with the average price. Thus, the effect of the aggregation may operate on some occasions to the disadvantage of the Fund. In addition, under certain circumstances, the Fund will not be charged the same commission or commission equivalent rates in connection with a bunched or aggregated order.

Subject to applicable law, BlackRock may select brokers that furnish BlackRock, the Fund, other BlackRock client accounts or personnel, directly or through correspondent relationships, with research or other appropriate services which provide, in BlackRock's view, appropriate assistance to BlackRock

69

in the investment decision-making process (including with respect to futures, fixed-price offerings and OTC transactions). Such research or other services may include, to the extent permitted by law, research reports on companies, industries and securities; economic and financial data; financial publications; proxy analysis; trade industry seminars; computer data bases; research-oriented software and other services and products.

Research or other services obtained in this manner may be used in servicing any or all of the Fund and other BlackRock client accounts, including in connection with BlackRock client accounts other than those that pay commissions to the broker relating to the research or other service arrangements. Such products and services may disproportionately benefit other BlackRock client accounts relative to the Fund based on the amount of brokerage commissions paid by the Fund and such other BlackRock client accounts. For example, research or other services that are paid for through one client's commissions may not be used in managing that client's account. In addition, other BlackRock client accounts may receive the benefit, including disproportionate benefits, of economies of scale or price discounts in connection with products and services that may be provided to the Fund and to such other BlackRock client accounts. To the extent that BlackRock uses soft dollars, it will not have to pay for those products and services itself.

BlackRock permits the usage of fund assets in the form of brokerage commissions to receive eligible brokerage and research services (collectively "eligible services") as permitted under Section 28(e) of the 1934 Act, generally referred to as "soft dollars." Commissions paid as soft dollars that consider the full array of eligible services may be higher than commissions paid for "execution only" services and may include services provided by third parties where the executing broker-dealer shares a portion of the commissions received with that third-party. A potential conflict exists when eligible services are paid for through soft dollars using fund assets as they are not paid by BlackRock using its own assets. BlackRock believes eligible services obtained through soft dollars enhance its investment decision-making capabilities, thereby increasing the prospects for higher investment returns, and recognizes certain eligible services may only be made available to BlackRock through the use of soft dollars. BlackRock only engages in soft dollar transactions that comply with applicable regulatory requirements and guidance which includes its requirement to seek best execution. The Fund does not currently participate in a soft dollar program; however, the Fund may be considered for and included in such a program at a future date.

BlackRock may utilize certain electronic crossing networks ("ECNs") (including, without limitation, ECNs in which BlackRock has an investment or other interest, to the extent permitted by applicable law) in executing client securities transactions for certain types of securities. These ECNs may charge fees for their services, including access fees and transaction fees. The transaction fees, which are similar to commissions or markups/markdowns, will generally be charged to clients and, like commissions and markups/markdowns, would generally be included in the cost of the securities purchased. Access fees may be paid by BlackRock even though incurred in connection with executing transactions on behalf of clients, including the Fund. In certain circumstances, ECNs may offer volume discounts that will reduce the access fees typically paid by BlackRock. BlackRock will only utilize ECNs consistent with its obligation to seek to obtain best execution in client transactions.

BlackRock owns a minority interest in, and is a member of, Members Exchange ("MEMX"), a newly created U.S. stock exchange. Transactions for the Fund may be executed on MEMX if third party brokers select MEMX as the appropriate venue for execution of orders placed by BlackRock traders on behalf of the Fund.

BlackRock has adopted policies and procedures designed to prevent conflicts of interest from influencing proxy voting decisions that it makes on behalf of advisory clients, including the Fund, and to help ensure that such decisions are made in accordance with BlackRock's fiduciary obligations to its

70

clients. Nevertheless, notwithstanding such proxy voting policies and procedures, actual proxy voting decisions of BlackRock may have the effect of favoring the interests of other clients or businesses of other divisions or units of BlackRock, provided that BlackRock believes such voting decisions to be in accordance with its fiduciary obligations. For a more detailed discussion of these policies and procedures, see the Proxy Voting Policy section of this SAI.

It is also possible that, from time to time, BlackRock may, subject to compliance with applicable law, purchase and hold shares of the Fund. Increasing the Fund's assets may enhance liquidity, investment flexibility and diversification and may compliance with applicable law, to sell into the market or redeem in Creation Units through an Authorized Participant at any time some or all of the shares of the Fund acquired for its own accounts. A large sale or redemption of shares of the Fund by BlackRock could significantly reduce the asset size of the Fund, which might have an adverse effect on the Fund's liquidity, investment flexibility, portfolio diversification, expense ratio or ability to comply with the listing requirements for the Fund. BlackRock seeks to consider the effect of redemptions on the Fund and other shareholders in deciding whether to redeem its shares but is not obligated to do so and may elect not to do so.

It is possible that the Fund may invest in securities of, or engage in transactions with, companies in which BlackRock has significant debt or equity investments or other interests. The Fund may also invest in issuances (such as structured notes) by entities for which BlackRock provides and is compensated for cash management services relating to the proceeds from the sale of such issuances. In making investment decisions for the Fund, BlackRock is not permitted to obtain or use material non-publicinformation acquired by any unit of BlackRock in the course of these activities. In addition, from time to time, the activities of BlackRock may limit the Fund's flexibility in purchases and sales of securities. As indicated below, BlackRock may engage in transactions with companies in which BlackRock-advised funds or other clients of BlackRock have an investment.

BlackRock and its personnel and other financial service providers may have interests in promoting sales of the Fund. With respect to BlackRock and its personnel, the remuneration and profitability relating to services to and sales of the Fund or other products may be greater than remuneration and profitability relating to services to and sales of certain funds or other products that might be provided or offered. BlackRock and its sales personnel may directly or indirectly receive a portion of the fees and commissions charged to the Fund or their shareholders. BlackRock and its advisory or other personnel may also benefit from increased amounts of assets under management. Fees and commissions may also be higher than for other products or services, and the remuneration and profitability to BlackRock and such personnel resulting from transactions on behalf of or management of the Fund may be greater than the remuneration and profitability resulting from other funds or products.

Third parties, including service providers to BlackRock or the Fund, may sponsor events (including, but not limited to, marketing and promotional activities and presentations, educational training programs and conferences) for registered representatives, other professionals and individual investors. There is a potential conflict of interest as such sponsorships may defray the costs of such activities to BlackRock, and may provide an incentive to BlackRock to retain such third parties to provide services to the Fund.

BlackRock may provide valuation assistance to certain clients with respect to certain securities or other investments and the valuation recommendations made for such clients' accounts may differ from the valuations for the same securities or investments assigned by the Fund's pricing vendors, especially if such valuations are based on broker-dealer quotes or other data sources unavailable to the Fund's pricing vendors. While BlackRock will generally communicate its valuation information or determinations to the Fund's pricing vendors and/or fund accountants, there may be instances where the Fund's pricing vendors or fund accountants assign a different valuation to a security or other

71

investment than the valuation for such security or investment determined or recommended by BlackRock.

As disclosed in more detail in the Determination of Net Asset Valuesection in this SAI, when market quotations are not readily available or are believed by BFA to be unreliable, the Fund's investments are valued at fair value by BFA. BFA has been designated as the Fund's valuation designee pursuant to Rule 2a-5 under the Investment Company Act and acts through BFA's Rule 2a-5 Committee (the "2a-5 Committee"), with assistance from other BFA pricing committees and in accordance with BFA's policies and procedures (the "Valuation Procedures"). When determining a "fair value price," the 2a-5 Committee seeks to determine the price that the Fund might reasonably expect to receive from the current sale of that asset or liability in an arm's-lengthtransaction. The price generally may not be determined based on what the Fund might reasonably expect to receive for selling an asset or liability at a later time or if it holds the asset or liability to maturity. While fair value determinations will be based upon all available factors that BFA deems relevant at the time of the determination, and may be based on analytical values determined by BFA using proprietary or third-party valuation models, fair value represents only a good faith approximation of the value of an asset or liability. The fair value of one or more assets or liabilities may not, in retrospect, be the price at which those assets or liabilities could have been sold during the period in which the particular fair values were used in determining the Fund's NAV. As a result, the Fund's sale or redemption of its shares at NAV, at a time when a holding or holdings are valued by the 2a-5 Committee at fair value, may have the effect of diluting or increasing the economic interest of existing shareholders and may affect the amount of revenue received by BFA with respect to services for which it receives an asset-based fee.

To the extent permitted by applicable law, the Fund may invest all or some of its short-term cash investments in any money market fund or similarly-managed private fund advised or managed by BlackRock. In connection with any such investments, the Fund, to the extent permitted by the 1940 Act, may pay its share of expenses of a money market fund or other similarly-managed private fund in which it invests, which may result in the Fund bearing some additional expenses.

BlackRock and its directors, officers and employees, may buy and sell securities or other investments for their own accounts and may have conflicts of interest with respect to investments made on behalf of the Fund. As a result of differing trading and investment strategies or constraints, positions may be taken by directors, officers and employees that are the same, different from or made at different times than positions taken for the Fund. To lessen the possibility that the Fund will be adversely affected by this personal trading, the Fund, BFA and BlackRock have each adopted a Code of Ethics in compliance with Section 17(j) of the Investment Company Act that restricts securities trading in the personal accounts of investment professionals and others who normally come into possession of information regarding the Fund's portfolio transactions. Each Code of Ethics is available by contacting BlackRock at the telephone number on the back cover of the Fund's Prospectus or by accessing the EDGAR Database on the SEC's Internet site at http://www.sec.gov, and copies may be obtained, after paying a duplicating fee, by e-mailat [email protected].

BlackRock will not purchase securities or other property from, or sell securities or other property to, the Fund, except that the Fund may in accordance with rules or guidance adopted under the 1940 Act engage in transactions with another Fund or accounts that are affiliated with the Fund as a result of common officers, directors, or investment advisers or pursuant to exemptive orders granted to the Fund and/or BlackRock by the SEC. These transactions would be effected in circumstances in which BlackRock determined that it would be appropriate for the Fund to purchase and another client of BlackRock to sell, or the Fund to sell and another client of BlackRock to purchase, the same security or instrument on the same day. From time to time, the activities of the Fund may be restricted because of regulatory requirements applicable to BlackRock and/or BlackRock's internal policies designed to comply with, limit the applicability of, or otherwise relate to such requirements. A client not advised by BlackRock

72

would not be subject to some of those considerations. There may be periods when BlackRock may not initiate or recommend certain types of transactions, or may otherwise restrict or limit its advice in certain securities or instruments issued by or related to companies for which BlackRock is performing advisory or other services or has proprietary positions. For example, when BlackRock is engaged to provide advisory or risk management services for a company, BlackRock may be prohibited from or limited in purchasing or selling securities of that company on behalf of the Fund, particularly where such services result in BlackRock obtaining material non-publicinformation about the company (e.g., in connection with participation in a creditors' committee). Similar situations could arise if personnel of BlackRock serve as directors of companies the securities of which the Fund wish to purchase or sell. However, if permitted by applicable law, and where consistent with BlackRock's policies and procedures (including the necessary implementation of appropriate information barriers), the Fund may purchase securities or instruments that are issued by such companies, are the subject of an advisory or risk management assignment by BlackRock, or where personnel of BlackRock are directors or officers of the issuer.

The investment activities of BlackRock for its proprietary accounts and for client accounts may also limit the investment strategies and rights of the Fund. For example, in certain circumstances where the Fund invest in securities issued by companies that operate in certain regulated industries,in certain emerging or international markets, or are subject to corporate or regulatory ownership restrictions, or invest in certain futures and derivative transactions, there may be limits on the aggregate amount invested by BlackRock for its proprietary accounts and for client accounts (including the Fund) that may not be exceeded without the grant of a license or other regulatory or corporate consent or, if exceeded, may cause BlackRock, the Fund or other client accounts to suffer disadvantages or business restrictions.

If certain aggregate ownership thresholds are reached either through the actions of BlackRock or the Fund or as a result of third-party transactions, the ability of BlackRock, on behalf of clients (including the Fund), to purchase or dispose of investments, or exercise rights or undertake business transactions, may be restricted by regulation or otherwise impaired. As a result, BlackRock, on behalf of its clients (including the Fund), may limit purchases, sell existing investments, or otherwise restrict, forgo or limit the exercise of rights (including transferring, outsourcing or limiting voting rights or forgoing the right to receive dividends) when BlackRock, in its sole discretion, deems it appropriate in light of potential regulatory or other restrictions on ownership or other consequences resulting from reaching investment thresholds.

In those circumstances where ownership thresholds or limitations must be observed, BlackRock seeks to allocate limited investment opportunities equitably among clients (including the Fund), taking into consideration benchmark weight and investment strategy. BlackRock has adopted certain controls designed to prevent the occurrence of a breach of any applicable ownership threshold or limits, including, for example, when ownership in certain securities nears an applicable threshold, BlackRock may remove such securities from the list of Deposit Securities to be delivered to the Fund in connection with purchases of Creation Units of the Fund and may limit purchases in such securities to the issuer's weighting in the applicable benchmark used by BlackRock to manage the Fund. If client (including Fund) holdings of an issuer exceed an applicable threshold and BlackRock is unable to obtain relief to enable the continued holding of such investments, it may be necessary to sell down these positions to meet the applicable limitations. In these cases, benchmark overweight positions will be sold prior to benchmark positions being reduced to meet applicable limitations.

In addition to the foregoing, other ownership thresholds may trigger reporting requirements to governmental and regulatory authorities, and such reports may entail the disclosure of the identity of a client or BlackRock's intended strategy with respect to such security or asset.

73

BlackRock may not serve as an Authorized Participant in the creation and redemption of BlackRock-advised ETFs.

Under an ETF Services Agreement, the Fund has retained BlackRock Investments, LLC, an Affiliate of BFA, to perform certain order processing, Authorized Participant communications, and related services in connection with the issuance and redemption of Creation Units of the Fund ("ETF Services"). BRIL will retain a portion of the standard transaction fee received from Authorized Participants on each creation or redemption order from the Authorized Participant for the ETF Services provided. BlackRock collaborated with, and received payment from, Citibank, N.A. ("Citibank") on the design and development of the ETF Services platform. Citibank may have, or from time to time may develop, additional relationships with BlackRock or funds managed by BFA and its affiliates.

BlackRock may maintain securities indices. To the extent permitted by applicable laws, the Fund may seek to license and use such indices as part of their investment strategy. Index based funds that seek to track the performance of securities indices also may use the name of the index or index provider in the fund name. Index providers, including BlackRock (to the extent permitted by applicable law), may be paid licensing fees for use of their index or index name. In instances where BlackRock charges a unitary management fee, BlackRock may have a financial incentive to use a BlackRock index that is less costly to BlackRock than a third party index. BlackRock may benefit from the Fund using BlackRock indices by creating increasing acceptance in the marketplace for such indices. BlackRock is not obligated to license its indices to the Fund and the Fund is under no obligation to use BlackRock indices. Any fund that enters into a license for a BlackRock index cannot be assured that the terms of any index licensing agreement with BlackRock will be as favorable as those terms offered to other licensees.

BlackRock may enter into contractual arrangements with third-party service providers to the Fund (e.g., custodians, administrators and index providers) pursuant to which BlackRock receives fee discounts or concessions in recognition of BlackRock's overall relationship with such service providers. BlackRock may also enter into contractual arrangements with such service providers pursuant to which BlackRock incurs additional costs if the service provider's services are terminated with respect to a Fund. To the extent that BlackRock is responsible for paying service providers out of its fees that is receives from the Fund, the benefits of lower fees, including any fee discounts or concessions, or any additional savings, may accrue, in whole or in part, to BlackRock, which could result in conflicts of interest relating to the use or termination of service providers to a Fund. In addition, conflicts of interest may arise with respect to contractual arrangements with third-party service providers to a Fund, or the selection of such providers, particularly in circumstances where BlackRock is negotiating on behalf of both funds that have a unitary management fee and those that do not or different service providers have different fee structures.

Conflicts of interest may arise as a result of simultaneous investment management of multiple client accounts by the BlackRock's investment professionals. For example, differences in the advisory fee structure may create the appearance of actual or potential conflicts of interest because such differences could create pecuniary incentives for BlackRock to favor one client account over another.

BlackRock owns or has an ownership interest in certain trading, portfolio management, operations and/or information systems used by Fund service providers. These systems are, or will be, used by the Fund service provider in connection with the provision of services to accounts managed by BlackRock and funds managed and sponsored by BlackRock, including the Fund, that engage the service provider (typically the custodian). The Fund's service provider remunerates BlackRock for the use of the systems. The Fund service provider's payments to BlackRock for the use of these systems may enhance the profitability of BlackRock.

74

BlackRock's receipt of fees from a service provider in connection with the use of systems provided by BlackRock may create an incentive for BlackRock to recommend that the Fund enter into or renew an arrangement with the service provider.

In recognition of a BlackRock client's overall relationship with BlackRock, BlackRock may offer special pricing arrangements for certain services provided by BlackRock. Any such special pricing arrangements will not apply to the client's investment in the Fund.

Present and future activities of BlackRock (including BFA) and its directors, officers and employees, in addition to those described in this section, may give rise to additional conflicts of interest.

Investment Advisory, Administrative and Distribution Services

Investment Adviser. BFA serves as investment adviser to the Fund pursuant to an investment advisory agreement between the Trust, on behalf of the Fund, and BFA. BFA is a California corporation indirectly owned by BlackRock, Inc. and is registered as an investment adviser under the Investment Advisers Act of 1940, as amended. Under the investment advisory agreement, BFA, subject to the supervision of the Board and in conformity with the stated investment policies of the Fund, manages and administers the Trust and the investment of the Fund's assets. BFA is responsible for making investment decisions for the Fund.

Pursuant to the investment advisory agreement, BFA may, from time to time, in its sole discretion and to the extent permitted by applicable law, appoint one or more sub-advisers,including, without limitation, affiliates of BFA, to perform investment advisory or other services with respect to the Fund. In addition, BFA may delegate certain of its investment advisory functions under the investment advisory agreement to one or more of its affiliates to the extent permitted by applicable law. BFA may terminate any or all sub-advisersor such delegation arrangements in its sole discretion upon appropriate notice at any time to the extent permitted by applicable law.

BFA is responsible, under the investment advisory agreement, for substantially all expenses of the Fund, including the cost of transfer agency, custody, fund administration, legal, audit and other services. BFA is not responsible for, and the Fund will bear the cost of, the management fees, interest expenses, taxes, expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions (other than any commitment fee relating to a committed line of credit), distribution fees or expenses, litigation expenses and extraordinary expenses (as determined by a majority of the Independent Trustees).

BFA has contractually agreed to waive 0.05% of the management fee through June 30, 2026. The agreement may be terminated upon 90 days' notice by a majority of the non-interested trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund.

BFA has contractually agreed to waive a portion of its management fees in an amount equal to the aggregate Acquired Fund Fees and Expenses, if any, attributable to investments by the Fund in other equity and fixed-income mutual funds and ETFs advised by BFA or its affiliates through June 30, 2025. BFA has also contractually agreed to waive a portion of its management fees by an amount equal to

75

the aggregate Acquired Fund Fees and Expenses, if any, attributable to investments by the Fund in money market funds advised by BFA or its affiliates through June 30, 2025. The agreement (with respect to either waiver) may be terminated upon 90 days' notice by a majority of the non-interested trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund.

BFA may also from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

The following table sets forth the management fee (net of any applicable waivers) at the annual rate (as a percentage of the Fund's average daily net assets) BFA received from the Fund for the fiscal year ended July 31, 2023 and the management fees (net of any applicable waivers) the Fund paid BFA for the fiscal years noted.

The investment advisory agreement with respect to the Fund continues in effect for two years from its effective date, and thereafter is subject to annual approval by (i) the Board, or (ii) the vote of a majority of the outstanding voting securities (as defined in the 1940 Act) of the Fund, provided that in either event such continuance also is approved by a majority of the Board members who are not interested persons (as defined in the 1940 Act) of the Fund, by a vote cast in person at a meeting called for the purpose of voting on such approval.

The investment advisory agreement with respect to the Fund is terminable without penalty, on 60 days' notice, by the Board or by a vote of the holders of a majority of the applicable Fund's outstanding voting securities (as defined in the 1940 Act). The investment advisory agreement is also terminable upon 60 days' notice by BFA and will terminate automatically in the event of its assignment (as defined in the 1940 Act).

Portfolio Managers. As of July 31, 2023, the individuals named as Portfolio Managers in the Fund's Prospectus were also primarily responsible for the day-to-daymanagement of other BlackRock funds and certain other types of portfolios and/or accounts as follows:

Pursuant to BFA's policy, investment opportunities are allocated equitably among the Fund and other portfolios and accounts. For example, under certain circumstances, an investment opportunity may be restricted due to limited supply in the market, legal constraints or other factors, in which event the investment opportunity will be allocated equitably among those portfolios and accounts, including the Fund, seeking such investment opportunity. As a consequence, from time to time the Fund may receive a smaller allocation of an investment opportunity than it would have if the Portfolio Managers and BFA and its affiliates did not manage other portfolios or accounts.

Like the Fund, the other portfolios or accounts for which the Portfolio Managers are primarily responsible for the day-to-dayportfolio management generally pay an asset-based fee to BFA or its affiliates, as applicable, for its advisory services. One or more of those other portfolios or accounts, however, may pay BFA or its affiliates a performance-based fee in lieu of, or in addition to, an asset-based fee for its advisory services. A portfolio or account with a performance-based fee would pay BFA or its affiliates a portion of that portfolio's or account's gains, or would pay BFA or its affiliates more for its services than would otherwise be the case if BFA or any of its affiliates meets or exceeds specified performance targets. Performance-based fee arrangements could present an incentive for BFA or its affiliates to devote greater resources, and allocate more investment opportunities, to the portfolios or accounts that have those fee arrangements, relative to other portfolios or accounts, in order to earn larger fees. Although BFA and each of its affiliates have an obligation to allocate resources and opportunities equitably among portfolios and accounts and intend to do so, shareholders of the Fund should be aware that, as with any group of portfolios and accounts managed by an investment adviser and/or its affiliates pursuant to varying fee arrangements, including performance-based fee arrangements, there is the potential for a conflict of interest, which may result in the Portfolio Managers favoring those portfolios or accounts with performance-based fee arrangements.

The tables below show, for each Portfolio Manager, the number of portfolios or accounts of the types set forth in the above tables and the aggregate of total assets in those portfolios or accounts with respect to which the investment management fees are based on the performance of those portfolios or accounts as of July 31, 2023:

Portfolio Manager Compensation Overview

The discussion below describes the Portfolio Managers' compensation as of July 31, 2023.

BlackRock, Inc.'s financial arrangements with its portfolio managers, its competitive compensation and its career path emphasis at all levels reflect the value senior management places on key resources. Compensation may include a variety of components and may vary from year to year based on a number of factors. The principal components of compensation include a base salary, a performance-based discretionary bonus, participation in various benefits programs and one or more of the incentive compensation programs established by BlackRock, Inc.

Base compensation.Generally, portfolio managers receive base compensation based on their position with the firm.

Discretionary Incentive Compensation. Discretionary incentive compensation is a function of several components: the performance of BlackRock, Inc., the performance of the portfolio manager's group within BlackRock, the investment performance, including risk-adjusted returns, of the firm's assets under management or supervision by that portfolio manager, and the individual's performance and contribution to the overall performance of these portfolios and BlackRock. Among other things, BlackRock's Chief Investment Officers make a subjective determination with respect to each portfolio manager's compensation based on the performance of the Fund and other accounts managed by each portfolio manager. Performance of multi-asset class funds is generally measured on a pre-taxbasis over various time periods including 1-,3-and 5-year periods, as applicable. With respect to these portfolio managers, such benchmarks for the Fund and other accounts are:

78

Distribution of Discretionary Incentive Compensation.Discretionary incentive compensation is distributed to portfolio managers in a combination of cash, deferred BlackRock, Inc. stock awards, and/or deferred cash awards that notionally track the return of certain BlackRock investment products.

Portfolio managers receive their annual discretionary incentive compensation in the form of cash. Portfolio managers whose total compensation is above a specified threshold also receive deferred BlackRock, Inc. stock awards annually as part of their discretionary incentive compensation. Paying a portion of discretionary incentive compensation in the form of deferred BlackRock, Inc. stock puts compensation earned by a portfolio manager for a given year "at risk" based on BlackRock's ability to sustain and improve its performance over future periods. In some cases, additional deferred BlackRock, Inc. stock may be granted to certain key employees as part of a long-term incentive award to aid in retention, align interests with long-term shareholders and motivate performance. Deferred BlackRock, Inc. stock awards are generally granted in the form of BlackRock, Inc. restricted stock units that vest pursuant to the terms of the applicable plan and, once vested, settle in BlackRock, Inc. common stock. The portfolio managers of this Fund have deferred BlackRock, Inc. stock awards.

For certain portfolio managers, a portion of the discretionary incentive compensation is also distributed in the form of deferred cash awards that notionally track the returns of select BlackRock investment products they manage, which provides direct alignment of portfolio manager discretionary incentive compensation with investment product results. Deferred cash awards vest ratably over a number of years and, once vested, settle in the form of cash. Only portfolio managers who manage specified products and whose total compensation is above a specified threshold are eligible to participate in the deferred cash award program.

Other Compensation Benefits.In addition to base compensation and discretionary incentive compensation, portfolio managers may be eligible to receive or participate in one or more of the following:

Incentive Savings Plans- BlackRock, Inc. has created a variety of incentive savings plans in which BlackRock, Inc. employees are eligible to participate, including a 401(k) plan, the BlackRock Retirement Savings Plan ("RSP"), and the BlackRock Employee Stock Purchase Plan ("ESPP"). The employer contribution components of the RSP include a company match equal to 50% of the first 8% of eligible pay contributed to the plan capped at $5,000 per year, and a company retirement contribution equal to 3-5%of eligible compensation up to the U.S. Internal Revenue Service (the "IRS") limit ($330,000 for 2023). The RSP offers a range of investment options, including registered investment companies and collective investment funds managed by the firm. BlackRock, Inc. contributions follow the investment direction set by participants for their own contributions or, absent participant investment direction, are invested into an index target date fund that corresponds to, or is closest to, the year in which the participant attains age 65. The ESPP allows for investment in BlackRock, Inc. common stock at a 5% discount on the fair market value of the stock on the purchase date. Annual participation in the ESPP is limited to the purchase of 1,000 shares of common stock or a dollar value of $25,000 based on its fair market value on the Purchase Date. All of the eligible portfolio managers are eligible to participate in these plans.

As of July 31, 2023, the Portfolio Managers did not beneficially own shares of the Fund.

Codes of Ethics.The Trust, BFA and the Distributor have adopted codes of ethics pursuant to Rule 17j-1under the 1940 Act. The codes of ethics permit personnel subject to the codes of ethics to invest in securities, subject to certain limitations, including securities that may be purchased or held by the Fund. Each code of ethics is available by contacting BlackRock at the telephone number on the back cover of the Fund's Prospectus or by accessing the EDGAR Database on the SEC's Internet site at http://www.sec.gov, and copies may be obtained, after paying a duplicating fee, by e-mailat [email protected].

79

Anti-Money Laundering Requirements.The Fund is subject to the USA PATRIOT Act (the "Patriot Act"). The Patriot Act is intended to prevent the use of the U.S. financial system in furtherance of money laundering, terrorism or other illicit activities. Pursuant to requirements under the Patriot Act, the Fund may request information from Authorized Participants to enable it to form a reasonable belief that it knows the true identity of its Authorized Participants. This information will be used to verify the identity of Authorized Participants or, in some cases, the status of financial professionals; it will be used only for compliance with the requirements of the Patriot Act.

The Fund reserves the right to reject purchase orders from persons who have not submitted information sufficient to allow the Fund to verify their identity. The Fund also reserves the right to redeem any amounts in the Fund from persons whose identity it is unable to verify on a timely basis. It is the Fund's policy to cooperate fully with appropriate regulators in any investigations conducted with respect to potential money laundering, terrorism or other illicit activities.

Administrator, Custodian and Transfer Agent.State Street Bank and Trust Company ("State Street") serves as administrator, custodian and transfer agent for the Fund. State Street's principal address is One Congress Street, Suite 1, Boston, Massachusetts 02114-2016. Pursuant to the Administration and Fund Accounting Services Agreement with the Trust, State Street provides necessary administrative, legal, tax and accounting and financial reporting services for the maintenance and operations of the Trust and the Fund. In addition, State Street makes available the office space, equipment, personnel and facilities required to provide such services. Pursuant to the Master Custodian Agreement with the Trust, State Street maintains, in separate accounts, cash, securities and other assets of the Trust and the Fund, keeps all necessary accounts and records and provides other services. State Street is required, upon the order of the Trust, to deliver securities held by State Street and to make payments for securities purchased by the Trust for the Fund. State Street is authorized to appoint certain foreign custodians or foreign custody managers for Fund investments outside the U.S. Pursuant to the Transfer Agency and Service Agreement with the Trust, State Street acts as a transfer agent for the Fund's authorized and issued shares of beneficial interest, and as dividend disbursing agent of the Trust. As compensation for these services, State Street receives certain out-of-pocketcosts, transaction fees and asset-based fees which are accrued daily and paid monthly by BFA from its management fee.

The following table sets forth the administration, custodian and transfer agency expenses of the Fund paid by BFA to State Street for the fiscal period noted.

Credit Agreement. The Trust, on behalf of the Fund, along with certain other funds managed by the Manager and its affiliates ("Participating Funds"), is a party to a 364-day,$2.5 billion credit agreement with a group of lenders, which facility terminates on April 11, 2024 unless otherwise extended or renewed (the "Credit Agreement"). The Fund can borrow up to (a) $750 million specifically designated for the Fund and another Participating Fund plus (b) of the remaining $1.75 billion aggregate commitment available to all Participating Funds, $350 million, subject to asset coverage and other limitations as specified in the Credit Agreement. The Fund may borrow under the Credit Agreement to meet shareholder redemptions and for other lawful purposes. However, the Fund may not borrow under the Credit Agreement for leverage. The Fund may borrow up to the maximum amount allowable under its current Prospectus and SAI, subject to various other legal, regulatory or contractual limits. Borrowing results in interest expense and other fees and expenses for the Fund which may impact the Fund's net expenses. The costs of borrowing may reduce the Fund's return. The Fund is charged its pro rata share of upfront fees and commitment fees on the aggregate commitment amount based on its net assets. If the Fund borrows pursuant to the Credit Agreement, the Fund will be charged interest at a variable rate.

Distributor.The Distributor's principal address is 1 University Square Drive, Princeton, NJ 08540. Shares are continuously offered for sale by the Fund through the Distributor or its agent only in Creation Units, as described in the Prospectus and below in the Creation and Redemption of Creation Unitssection of this SAI. Fund shares in amounts less than Creation Units are generally not distributed by the Distributor or its agent. The Distributor or its agent will arrange for the delivery of the Prospectus and, upon request, this SAI to persons purchasing Creation Units and will maintain records of both orders placed with it or its agents and confirmations of acceptance furnished by it or its agents. The Distributor is a broker-dealer registered under the Securities Exchange Act of 1934, as amended (the "1934 Act"), and a member of the Financial Industry Regulatory Authority, Inc. ("FINRA"). The Distributor is also licensed as a broker-dealer in all 50 U.S. states, as well as in Puerto Rico, the U.S. Virgin Islands and the District of Columbia.

The Distribution Agreement for the Fund provides that it may be terminated at any time, without the payment of any penalty, on at least 60 days' prior written notice to the other party following (i) the vote of a majority of the Independent Trustees, or (ii) the vote of a majority of the outstanding voting securities (as defined in the 1940 Act) of the Fund. The Distribution Agreement will terminate automatically in the event of its assignment (as defined in the 1940 Act).

The Distributor may also enter into agreements with securities dealers ("Soliciting Dealers") who will solicit purchases of Creation Units of Fund shares. Such Soliciting Dealers may also be Authorized Participants (as described below), Depository Trust Company ("DTC") participants and/or investor services organizations.

BFA or its affiliates may, from time to time and from its own resources, pay, defray or absorb costs relating to distribution, including payments out of its own resources to the Distributor, or to otherwise promote the sale of shares.

Securities Lending.To the extent that the Fund engages in securities lending, the Fund conducts its securities lending pursuant to SEC exemptive relief, and BTC acts as securities lending agent for the Fund, subject to the overall supervision of BFA, pursuant to a written agreement (the "Securities Lending Agency Agreement").

To the extent the Fund engages in securities lending, the Fund retains a portion of securities lending income and remits a remaining portion to BTC as compensation for its services as securities lending agent. Securities lending income is generally equal to the total of income earned from the reinvestment of cash collateral (and excludes collateral investment fees as defined below), and any fees or other payments to and from borrowers of securities. As securities lending agent, BTC bears all operational costs directly related to securities lending. The Fund is responsible for fees in connection with the investment of cash collateral received for securities on loan in money market funds advised by BFA or its affiliates and such fees will not be subject to any waivers. However, BTC has agreed to reduce the amount of securities lending income it receives in order to effectively limit the collateral investment fees the Fund bears to an annual rate of 0.04% (the "collateral investment fees"). Such money market fund shares will not be subject to a sales load, distribution fee or service fee. If the board of directors of the money market fund, including the majority of the non-interesteddirectors of the money market fund, determines it to be in the best interests of the money market fund, the money market fund will impose a discretionary liquidity fee of up to 2% on the value of all shares redeemed. Discretionary liquidity fees, if imposed, may be terminated at any time at the discretion of the board of directors of the money market fund. The shares of the money market fund purchased by the Fund would be subject to any such discretionary liquidity fee imposed.

81

Under the securities lending program, the Fund is categorized into a specific asset class. The determination of the Fund's asset class category (fixed-income, domestic equity, international equity, or fund-of-funds),each of which may be subject to a different fee arrangement, is based on a methodology agreed to between the Trust and BTC.

Pursuant to the securities lending agreement: (i) if the Fund was to engage in securities lending, the Fund retains 82% of securities lending income (which excludes collateral investment fees), and (ii) this amount can never be less than 70% of the sum of securities lending income plus collateral investment fees.

In addition, commencing the business day following the date that the aggregate securities lending income earned across the BlackRock Fixed-Income Complex in a calendar year exceeds a specified threshold, the Fund, pursuant to the securities lending agreement, will receive for the remainder of that calendar year securities lending income as follows: if the Fund were to engage in securities lending, (i) 85% of securities lending income (which excludes collateral investment fees); and (ii) this amount can never be less than 70% of the sum of securities lending income plus collateral investment fees.

The Fund had no income and fees/compensation related to its securities lending activities during its most recent fiscal year ended July 31, 2023.

Payments by BFA and its Affiliates.BFA and/or its affiliates ("BFA Entities") may pay certain broker-dealers, registered investment advisers, banks and other financial intermediaries ("Intermediaries") for certain activities related to the Fund, other BFA-advisedETFs or exchange-traded products in general. BFA Entities make these payments from their own assets and not from the assets of the Fund. Although a portion of BFA Entities' revenue comes directly or indirectly in part from fees paid by the Fund, BFA-advisedETFs or exchange-traded products, these payments do not increase the price paid by investors for the purchase of shares of, or the cost of owning, the Fund, other BFA-advisedETFs or exchange-traded products. BFA Entities make payments for Intermediaries' participation in activities that are designed to make registered representatives, other professionals and individual investors more knowledgeable about exchange-traded products, including the Fund and other BFA-advisedETFs, or for other activities, such as participation in marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems ("Education Costs"). BFA Entities also make payments to Intermediaries for certain printing, publishing and mailing costs or materials relating to the Fund, other BFA-advisedETFs or exchange-traded products ("Publishing Costs"). In addition, BFA Entities make payments to Intermediaries that make shares of the Fund, other BFA-advisedETFs or exchange-traded products available to their clients, develop new products that feature BlackRock, create educational content about the Fund, other BFA-advised ETFs or exchange-traded products that is featured on an Intermediary's platform, or otherwise promote the Fund, other BFA-advisedETFs and exchange-traded products. BFA Entities may also reimburse expenses or make payments from their own assets to Intermediaries or other persons in consideration of services or other activities that the BFA Entities believe may benefit the BlackRock business or facilitate investment in the Fund, other BFA-advisedETFs or exchange-traded products. Payments of the type described above are sometimes referred to as revenue-sharing payments.

Payments to an Intermediary may be significant to the Intermediary, and amounts that Intermediaries pay to your salesperson or other investment professional may also be significant for your salesperson or other investment professional. Because an Intermediary may make decisions about which investment options it will recommend or make available to its clients, what services to provide for various products or what marketing content to make available to its clients based on payments it receives or is eligible to receive, such payments may create conflicts of interest between the Intermediary and its clients. These financial incentives may cause the Intermediary to recommend the Fund, other BFA-advisedETFs or exchange-traded products or otherwise promote the Fund, other

82

BFA-advised ETFs or exchange-traded products over other investments. The same conflicts of interest and financial incentives exist with respect to your salesperson or other investment professional if he or she receives similar payments from his or her Intermediary firm.

In addition to the payments described above, BFA Entities have developed proprietary tools, calculators and related interactive or digital content that is made available through the www.blackrock.com website at no additional cost to Intermediaries. BlackRock may configure these tools and calculators and localize the content for Intermediaries as part of its customary digital marketing support and promotion of the Fund, other BFA-advisedETFs, exchange-traded products and BlackRock mutual funds.

As of March 1, 2013, BFA Entities have contractual arrangements to make payments (in addition to payments for Education Costs or Publishing Costs) to one Intermediary, Fidelity Brokerage Services LLC ("FBS"). Effective June 4, 2016, this relationship was expanded to include National Financial Services, LLC ("NFS"), an affiliate of FBS. Pursuant to this special, long-term and significant arrangement (the "Marketing Program"), FBS, NFS and certain of their affiliates (collectively "Fidelity") have agreed, among other things, to actively promote iShares funds to customers, investment professionals and other intermediaries and in advertising campaigns as the preferred exchange-traded product, to offer certain iShares funds in certain Fidelity platforms and investment programs, in some cases at a waived or reduced commission rate or ticket charge, and to provide marketing data to BFA Entities. BFA Entities have agreed to facilitate the Marketing Program by, among other things, making certain payments to FBS and NFS for marketing and implementing certain brokerage and investment programs. Upon termination of the arrangement, the BFA Entities will make additional payments to FBS and/or NFS based upon a number of criteria, including the overall success of the Marketing Program and the level of services provided by FBS and NFS during the wind-down period.

In addition, BFA Entities may enter into other contractual arrangements with Intermediaries and certain other third parties that the BFA Entities believe may benefit the BlackRock business or facilitate investment in BlackRock funds. Such agreements may include payments by BFA Entities to such Intermediaries and third parties for data collection and provision, technology support, platform enhancement, or educational content, co-marketing and cross-promotional efforts. Payments made pursuant to such arrangements may vary in any year and may be different for different Intermediaries and third parties. In certain cases, the payments to Intermediaries are subject to certain minimum payment levels or tiered payments. As of the date of this SAI, the Intermediaries and other third parties receiving one or more types of the contractual payments described above include (in addition to FBS and NFS): Advisor Credit Exchange, Avantax Investment Services, Inc., BNY Mellon Capital Markets, LLC, BNY Mellon Performance & Risk Analytics, LLC, Charles Schwab & Co., Inc., Clearstream Fund Centre AG, Commonwealth Equity Services, LLC, Dorsey Wright and Associates, LLC, E*Trade Securities LLC, Envestnet Asset Management, Inc., eToro USA Securities Inc., LPL Financial LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, Morgan Stanley Smith Barney LLC, Northwestern Mutual Investment Services, LLC, Orion Portfolio Solutions, LLC, Pershing LLC, Public Holdings, Inc., Raymond James Financial Services, Inc., Riskalyze, Inc., Sanctuary Wealth Group, LLC, Stash Investments LLC, TD Ameritrade, Inc., UBS Financial Services Inc., Wells Fargo Clearing Services, LLC and Wells Fargo Advisors Financial Network, LLC. Any additions, modifications, or deletions to Intermediaries and other third parties listed above that have occurred since the date of this SAI are not included in the list.

Further, BFA Entities make Education Costs and Publishing Costs payments to other Intermediaries that are not listed in the immediately preceding paragraph. BFA Entities may determine to make such payments based on any number of metrics. For example, BFA Entities may make payments at year-endor other intervals in a fixed amount, an amount based upon an Intermediary's services at defined levels or an amount based on the Intermediary's net sales of one or more BFA-advisedETFs

83

in a year or other period, any of which arrangements may include an agreed-upon minimum or maximum payment, or any combination of the foregoing. As of the date of this SAI, BFA anticipates that the payments paid by BFA Entities in connection with the Fund, BFA-advisedETFs and exchange-traded products in general will be immaterial to BFA Entities in the aggregate for the next year. Please contact your salesperson orother investment professional for more information regarding any such payments or financial incentives his or her Intermediary firm may receive. Any payments made, or financial incentives offered, by the BFA Entities to an Intermediary may create the incentive for the Intermediary to encourage customers to buy shares of the Fund, other BFA-advisedETFs or other exchange-traded products.

The Fund may participate in certain market maker incentive programs of a national securities exchange in which an affiliate of the Fund would pay a fee to the exchange used for the purpose of incentivizing one or more market makers in the securities of the Fund to enhance the liquidity and quality of the secondary market of securities of the Fund. The fee would then be credited by the exchange to one or more market makers that meet or exceed liquidity and market quality standards with respect to the securities of the Fund. Each market maker incentive program is subject to approval from the SEC. Any such fee payments made to an exchange will be made by an affiliate of the Fund solely for the benefit of the Fund and will not be paid from any Fund assets. Other funds managed by BFA may also participate in such programs.

Determination of Net Asset Value

Valuation of Shares.The NAV for the Fund is generally calculated as of the close of regular trading hours of the New York Stock Exchange ("NYSE") (normally 4:00 p.m., Eastern time) on each business day the NYSE is open. Valuation of securities held by the Fund is as follows:

Fixed-Income Investments.Fixed-income securities for which market quotations are readily available are generally valued using such securities' current market value. The Fund values fixed-income portfolio securities using the last available bid prices or current market quotations provided by dealers or prices (including evaluated prices) supplied by the Fund's approved independent third-party pricing services, each in accordance with the Valuation Procedures. The pricing services may use matrix pricing or valuation models that utilize certain inputs and assumptions to derive values, including transaction data (e.g., recent representative bids and offers), credit quality information, perceived market movements, news, and other relevant information and by other methods, which may include consideration of: yields or prices of securities of comparable quality, coupon, maturity and type; indications as to values from dealers; general market conditions; and/or other factors and assumptions. Pricing services generally value fixed-income securities assuming orderly transactions of an institutional round lot size, but the Fund may hold or transact in such securities in smaller, odd lot sizes. Odd lots may trade at lower prices than institutional round lots. The amortized cost method of valuation may be used with respect to debt obligations with sixty days or less remaining to maturity unless BlackRock determines in good faith that such method does not represent fair value. Loan participation notes are generally valued at the mean of the last available bid prices from one or more brokers or dealers as obtained from independent third-party pricing services. Certain fixed-income investments, including asset-backed and mortgage-related securities, may be valued based on valuation models that consider the estimated cash flows of each tranche of the entity, establish a benchmark yield and develop an estimated tranche-specific spread to the benchmark yield based on the unique attributes of the tranche.

84

Underlying Funds.Shares of underlying ETFs will be valued at their most recent closing price on an Exchange. Shares of underlying money market funds will be valued at their NAV.

General Valuation Information.The price the Fund could receive upon the sale of any particular portfolio investment may differ from the Fund's valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued using a fair valuation methodology or a price provided by an independent pricing service. As a result, the price received upon the sale of an investment may be less than the value ascribed by the Fund, and the Fund could realize a greater than expected loss or lesser than expected gain upon the sale of the investment. The Fund's ability to value its investment may also be impacted by technological issues and/or errors by pricing services or other third-party service providers.

All cash, receivables and current payables are carried on the Fund's books at their fair value.

Prices obtained from independent third-party pricing services, broker-dealers or market makers to value the Fund's securities and other assets and liabilities are based on information available at the time the Fund values its assets and liabilities. In the event that a pricing service quotation is revised or updated subsequent to the day on which the Fund valued such security or other asset or liability, the revised pricing service quotation generally will be applied prospectively. Such determination will be made considering pertinent facts and circumstances surrounding the revision.

In the event that application of the methods of valuation discussed above result in a price for a security which is deemed not to be representative of the fair market value of such security, the security will be valued by, under the direction of or in accordance with a method approved by BlackRock, the Fund's valuation designee, as reflecting fair value. All other assets and liabilities (including securities for which market quotations are not readily available) held by the Fund (including restricted securities) are valued at fair value as determined in good faith by BlackRock pursuant to the Valuation Procedures. Any assets and liabilities that are denominated in a foreign currency are converted into U.S. dollars using prevailing market rates on the date of valuation as quoted by one or more data service providers.

Certain of the securities acquired by the Fund may be traded on foreign exchanges or OTC markets on days on which the Fund's NAV is not calculated. In such cases, the NAV of the Fund's shares may be significantly affected on days when Authorized Participants can neither purchase nor redeem shares of the Fund.

Generally, trading in non-U.S.securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

Fair Value.When market quotations are not readily available or are believed in good faith by BFA to be unreliable, the Fund's investments are valued at fair value ("Fair Value Assets"). Fair Value Assets are valued by BFA in accordance with the Valuation Procedures. Pursuant to Rule 2a-5 under the Investment Company Act, the Board has designated BFA as the valuation designee for the Fund. BFA may reasonably conclude that a market quotation is not readily available or is unreliable if, among other things, a security or other asset or liability does not have a price source due to its complete lack of trading, if BFA believes that a market quotation from a broker-dealer or other source is unreliable (e.g., where it varies significantly from a recent trade, or no longer reflects the fair value of the security or other asset or liability subsequent to the most recent market quotation), or where the security or other asset or liability is only thinly traded or due to the occurrence of a significant event subsequent to the most recent market quotation. For this purpose, a "significant event" is deemed to occur if BFA determines, in its reasonable business judgment, that an event has occurred after the close of trading

85

for an asset or liability but prior to or at the time of pricing the Fund's assets or liabilities, and that the event is likely to cause a material change to the closing market price of the assets held by, or liabilities of, the Fund. Non-U.S.securities whose values are affected by volatility that occurs in global markets or in related or highly correlated assets (e.g., American Depositary Receipts, Global Depositary Receipts or substantially identical ETFs) on a trading day after the close of non-U.S.securities markets may be fair valued. On any day the NYSE is open and a foreign market or the primary exchange on which a foreign asset or liability is traded is closed, such asset or liability will be valued using the prior day's price, provided that BFA is not aware of any significant event or other information that would cause such price to no longer reflect the fair value of the asset or liability, in which case such asset or liability would be treated as a Fair Value Asset. In all cases, on days where non-U.S.securities markets are closed, BFA will determine the fair value of stocks traded on that local market, in accordance with the Valuation Procedures. Fair value adjustments may be calculated by referring to instruments and markets that have continued to trade, such as ETFs, correlated stock market indices or index futures.

BFA's Rule 2a-5 Committee is responsible for reviewing and approving methodologies by investment type and significant inputs used in the fair valuation of Fund assets or liabilities. In addition, the Fund's accounting agent assists BFA by periodically endeavoring to confirm the prices it receives from all third-party pricing services, index providers and broker-dealers, and regularly evaluating the values assigned to the securities and other assets and liabilities of the Fund. The pricing of all Fair Value Assets is subsequently reported to the Board or a committee thereof.

When determining the price for a Fair Value Asset, BFA will seek to determine the price that the Fund might reasonably expect to receive upon the current sale of that asset or liability in an arm's-lengthtransaction on the date on which the assets or liabilities are being valued, and does not seek to determine the price that the Fund might expect to receive for selling the asset, or the cost of extinguishing a liability, at a later time or if it holds the asset or liability to maturity. Fair value determinations will be based upon all available factors that BFA deems relevant at the time of the determination, and may be based on analytical values determined by BlackRock using proprietary or third-party valuation models.

Fair value represents a good faith approximation of the value of an asset or liability. When determining the fair value of an asset, one or more of a variety of fair valuation methodologies may be used (depending on certain factors, including the asset type). For example, the asset may be priced on the basis of the original cost of the investment or, alternatively, using proprietary or third-party models (including models that rely upon direct portfolio management pricing inputs and which reflect the significance attributed to the various factors and assumptions being considered). Prices of actual, executed or historical transactions in the relevant asset and/or liability (or related or comparable assets and/or liabilities) or, where appropriate, an appraisal by a third-party experienced in the valuation of similar assets and/or liabilities, may also be used as a basis for establishing the fair value of an asset or liability. The fair value of one or more assets or liabilities may not, in retrospect, be the price at which those assets or liabilities could have been sold during the period in which the particular fair values were used in determining the Fund's NAV. As a result, the Fund's sale or redemption of its shares at NAV, at a time when a holding or holdings are valued at fair value, may have the effect of diluting or increasing the economic interest of existing shareholders.

The Fund's annual audited financial statements, which are prepared in accordance with accounting principles generally accepted in the United States of America ("US GAAP"), follow the requirements for valuation set forth in Financial Accounting Standards Board Accounting Standards Codification Topic 820, "Fair Value Measurements and Disclosures" ("ASC 820"), which defines and establishes a framework for measuring fair value under US GAAP and expands financial statement disclosure requirements relating to fair value measurements. Generally, ASC 820 and other accounting rules applicable to funds and various

86

assets in which they invest are evolving. Such changes may adversely affect the Fund. For example, the evolution of rules governing the determination of the fair market value of assets or liabilities to the extent such rules become more stringent would tend to increase the cost and/or reduce the availability of third-party determinations of fair market value. This may in turn increase the costs associated with selling assets or affect their liquidity due to the Fund's inability to obtain a third-party determination of fair market value.

Brokerage Transactions

Subject to policies established by the Board, BFA is primarily responsible for the execution of the Fund's portfolio transactions and the allocation of brokerage. BFA does not execute transactions through any particular broker or dealer, but seeks to obtain the best net results for the Fund, taking into account such factors as price (including the applicable brokerage commission or dealer spread), size of order, difficulty of execution, operational facilities of the firm and the firm's risk and skill in positioning blocks of securities. While BFA generally seeks reasonable trade execution costs, the Fund does not necessarily pay the lowest spread or commission available, and payment of the lowest commission or spread is not necessarily consistent with obtaining the best price and execution in particular transactions. Subject to applicable legal requirements, BFA may select a broker based partly upon brokerage or research services provided to BFA and its clients, including the Fund. In return for such services, BFA may cause the Fund to pay a higher commission than other brokers would charge if BFA determines in good faith that the commission is reasonable in relation to the services provided.

In selecting brokers or dealers to execute portfolio transactions, BFA seeks to obtain the best price and most favorable execution for the Fund and may take into account a variety of factors including: (i) the size, nature and character of the security or instrument being traded and the markets in which it is purchased or sold; (ii) the desired timing of the transaction; (iii) BFA's knowledge of the expected commission rates and spreads currently available; (iv) the activity existing and expected in the market for the particular security or instrument, including any anticipated execution difficulties; (v) the full range of brokerage services provided; (vi) the broker's or dealer's capital; (vii) the quality of research and research services provided; (viii) the reasonableness of the commission, dealer spread or its equivalent for the specific transaction; and (ix) BFA's knowledge of any actual or apparent operational problems of a broker or dealer. Brokers may also be selected because of their ability to handle special or difficult executions, such as may be involved in large block trades, thinly traded securities, or other circumstances.

Section 28(e) of the 1934 Act ("Section 28(e)") permits a U.S. investment adviser, under certain circumstances, to cause an account to pay a broker or dealer a commission for effecting a transaction in securities that exceeds the amount another broker or dealer would have charged for effecting the same transaction in recognition of the value of brokerage and research services provided by that broker or dealer. This includes commissions paid on riskless principal transactions in securities under certain conditions.

From time to time, the Fund may purchase new issues of securities in a fixed price offering. In these situations, the broker may be a member of the selling group that will, in addition to selling securities, provide BFA with research services. FINRA has adopted rules expressly permitting these types of arrangements under certain circumstances. Generally, the broker will provide research "credits" in these situations at a rate that is higher than that available for typical secondary market transactions. These arrangements may not fall within the safe harbor of Section 28(e).

87

OTC issues, including most fixed-income securities such as corporate debt and U.S. Government securities, are normally traded on a "net" basis without a stated commission, through dealers acting for their own account and not as brokers. The Fund will primarily engage in transactions with these dealers or deal directly with the issuer unless a better price or execution could be obtained by using a broker. Prices paid to a dealer with respect to both foreign and domestic securities will generally include a "spread," which is the difference between the prices at which the dealer is willing to purchase and sell the specific security at the time, and includes the dealer's normal profit.

Under the 1940 Act, persons affiliated with the Fund and persons who are affiliated with such affiliated persons are prohibited from dealing with the Fund as principal in the purchase and sale of securities unless a permissive order allowing such transactions is obtained from the SEC. Since transactions in the OTC market usually involve transactions with the dealers acting as principal for their own accounts, the Fund will not deal with affiliated persons and affiliated persons of such affiliated persons in connection with such transactions. The Fund will not purchase securities during the existence of any underwriting or selling group relating to such securities of which BFA, BRIL or any affiliated person (as defined in the 1940 Act) thereof is a member except pursuant to procedures adopted by the Board in accordance with Rule 10f-3under the 1940 Act.

Purchases of money market instruments by the Fund are made from dealers, underwriters and issuers. The Fund do not currently expect to incur any brokerage commission expense on such transactions because money market instruments are generally traded on a "net" basis with dealers acting as principal for their own accounts without a stated commission. The price of the security, however, usually includes a profit to the dealer.

BFA may, from time to time, effect trades on behalf of and for the account of the Fund with brokers or dealers that are affiliated with BFA, in conformity with Rule 17e-1under the 1940 Act and SEC rules and regulations. Under these provisions, any commissions paid to affiliated brokers or dealers must be reasonable and fair compared to the commissions charged by other brokers or dealers in comparable transactions.

Securities purchased in underwritten offerings include a fixed amount of compensation to the underwriter, generally referred to as the underwriter's concession or discount. When securities are purchased or sold directly from or to an issuer, no commissions or discounts are paid.

Investment decisions for the Fund and for other investment accounts managed by BFA and the other Affiliates are made independently of each other in light of differing conditions. A variety of factors will be considered in making investment allocations. These factors include: (i) investment objectives or strategies for particular accounts, including sector, industry, country or region and capitalization weightings; (ii) tax considerations of an account; (iii) risk or investment concentration parameters for an account; (iv) supply or demand for a security at a given price level; (v) size of available investment; (vi) cash availability and liquidity requirements for accounts; (vii) regulatory restrictions; (viii) minimum investment size of an account; (ix) relative size of account; and (x) such other factors as may be approved by BlackRock's general counsel. Moreover, investments may not be allocated to one client account over another based on any of the following considerations: (i) to favor one client account at the expense of another; (ii) to generate higher fees paid by one client account over another or to produce greater performance compensation to BlackRock; (iii) to develop or enhance a relationship with a client or prospective client; (iv) to compensate a client for past services or benefits rendered to BlackRock or to induce future services or benefits to be rendered to BlackRock; or (v) to manage or equalize investment performance among different client accounts. BFA and the other Affiliates may deal, trade and invest for their own respective accounts in the types of securities in which the Fund may invest.

88

Initial public offerings ("IPOs") of securities may be over-subscribed and subsequently trade at a premium in the secondary market. When BFA is given an opportunity to invest in such an initial offering or "new" or "hot" issue, the supply of securities available for client accounts is often less than the amount of securities the accounts would otherwise take. In order to allocate these investments fairly and equitably among client accounts over time, each portfolio manager or a member of his or her respective investment team will indicate to BFA's trading desk their level of interest in a particular offering with respect to eligible clients' accounts for which that team is responsible. IPOs of U.S. equity securities will be identified as eligible for particular client accounts that are managed by portfolio teams who have indicated interest in the offering based on market capitalization of the issuer of the security and the investment mandate of the client account and in the case of international equity securities, the country where the offering is taking place and the investment mandate of the client account. Generally, shares received during the IPO will be allocated among participating client accounts within each investment mandate on a pro ratabasis. This pro rataallocation may result in the Fund receiving less of a particular security than if pro-ratinghad not occurred. All allocations of securities will be subject, where relevant, to share minimums established for accounts and compliance constraints. In situations where supply is too limited to be allocated among all accounts for which the investment is eligible, portfolio managers may rotate such investment opportunities among one or more accounts so long as the rotation system provides for fair access for all client accounts over time. Other allocation methodologies that are considered by BFA to be fair and equitable to clients may be used as well.

Because different accounts may have differing investment objectives and policies, BFA may buy and sell the same securities at the same time for different clients based on the particular investment objective, guidelines and strategies of those accounts. For example, BFA may decide that it may be entirely appropriate for a growth fund to sell a security at the same time a value fund is buying that security. To the extent that transactions on behalf of more than one client of BFA or the other Affiliates during the same period increase the demand for securities being purchased or the supply of securities being sold, there may be an adverse effect on price. For example, sales of a security by BlackRock on behalf of one or more of its clients may decrease the market price of such security, adversely impacting other BlackRock clients that still hold the security. If purchases or sales of securities arise for consideration at or about the same time that would involve the Fund or other clients or funds for which BFA or another Affiliate act as investment manager, transactions in such securities will be made, insofar as feasible, for the respective funds and clients in a manner deemed equitable to all.

In certain instances, BFA may find it efficient for purposes of seeking to obtain best execution, to aggregate or "bunch" certain contemporaneous purchases or sale orders of its advisory accounts and advisory accounts of affiliates. In general, all contemporaneous trades for client accounts under management by the same portfolio manager or investment team will be bunched in a single order if the trader believes the bunched trade would provide each client with an opportunity to achieve a more favorable execution at a potentially lower execution cost. The costs associated with a bunched order will be shared pro rataamong the clients in the bunched order. Generally, if an order for a particular portfolio manager or management team is filled at several different prices through multiple trades, all accounts participating in the order will receive the average price (except in the case of certain international markets where average pricing is not permitted). While in some cases this practice could have a detrimental effect upon the price or value of the security as far as the Fund is concerned, in other cases it could be beneficial to the Fund. Transactions effected by BFA or the other Affiliates on behalf of more than one of its clients during the same period may increase the demand for securities being purchased or the supply of securities being sold, causing an adverse effect on price. The trader will give the bunched order to the broker-dealer that the trader has identified as being able to provide the best execution of the order. Orders for purchase or sale of securities will be placed within a reasonable amount of time of the order receipt and bunched orders will be kept bunched only long enough to execute the order.

89

The table below sets forth the brokerage commissions paid by the Funds for the fiscal periods noted.

The following table shows the dollar amount of brokerage commissions paid to brokers for providing Section 28(e) research/brokerage services under Section 28(e) of the Securities Exchange Act of 1934, as amended, and the approximate dollar amount of the transactions involved for the fiscal year ended July 31, 2023. The provision of Section 28(e) research/brokerage services was not necessarily a factor in the placement of all brokerage business with such brokers.

As of July 31, 2023, the Trust, on behalf of the Fund, held no securities of its regular brokers or dealers (as defined in Rule 10b-1 under the Investment Company Act) whose shares were purchased during the fiscal year ended July 31, 2023.

The Fund's purchase and sale orders for securities may be combined with those of other investment companies, clients or accounts that BlackRock manages or advises. If purchases or sales of portfolio securities of the Fund and one or more other accounts managed or advised by BlackRock are considered at or about the same time, transactions in such securities are allocated among the Fund and the other accounts in a manner deemed equitable to all by BlackRock. In some cases, this procedure could have a detrimental effect on the price or volume of the security as far as the Fund is concerned. However, in other cases, it is possible that the ability to participate in volume transactions and to negotiate lower transaction costs will be beneficial to the Fund. BlackRock may deal, trade and invest for its own account in the types of securities in which the Fund may invest. BlackRock may, from time to time, effect trades on behalf of and for the account of the Fund with brokers or dealers that are affiliated with BFA, in conformity with the 1940 Act and SEC rules and regulations. Under these provisions, any commissions paid to affiliated brokers or dealers must be reasonable and fair compared to the commissions charged by other brokers or dealers in comparable transactions. The Fund will not deal with affiliates in principal transactions unless permitted by applicable SEC rules or regulations, or by SEC exemptive order.

Portfolio turnover may vary from year to year, as well as within a year. High turnover rates may result in comparatively greater brokerage expenses.

Additional Information Concerning the Trust

Shares. The Trust currently consists of 4 investment series or portfolio called a fund. The Trust issues shares of beneficial interests in the funds with no par value. The Board may establish and designate additional funds.

Each share issued by a fund has a pro ratainterest in the assets of that fund. Shares have no preemptive, exchange, subscription or conversion rights and are freely transferable. Each share is entitled to participate equally in dividends and distributions declared by the Board with respect to the relevant fund, and in the net distributable assets of such fund on liquidation.

90

Each share has one vote with respect to matters upon which the shareholder is entitled to vote. In any matter submitted to shareholders for a vote, the Fund shall hold a separate vote, provided that shareholders of all affected funds will vote together when: (i) required by the 1940 Act, or (ii) the Trustees determine that the matter affects the interests of more than one fund.

Under Delaware law, the Trust is not required to hold an annual meeting of shareholders unless required to do so under the 1940 Act. The policy of the Trust is not to hold an annual meeting of shareholders unless required to do so under the 1940 Act. All shares (regardless of the fund) have noncumulative voting rights in the election of members of the Board. Under Delaware law, Trustees of the Trust may be removed by vote of the shareholders.

Following the creation of the initial Creation Unit(s) of shares of a fund and immediately prior to the commencement of trading in such fund's shares, a holder of shares may be a "control person" of the fund, as defined in Rule 0-1under the 1940 Act. A fund cannot predict the length of time for which one or more shareholders may remain a control person of the fund.

Shareholders may make inquiries by writing to BlackRock ETF Trust II, c/o BlackRock Investments, LLC, 1 University Square Drive, Princeton, NJ 08540.

Absent an applicable exemption or other relief from the SEC or its staff, beneficial owners of more than 5% of the shares of a fund may be subject to the reporting provisions of Section 13 of the 1934 Act and the SEC's rules promulgated thereunder. In addition, absent an applicable exemption or other relief from the SEC or its staff, officers and trustees of a fund and beneficial owners of 10% of the shares of a fund ("Insiders") may be subject to the insider reporting, short-swing profit and short sale provisions of Section 16 of the 1934 Act and the SEC's rules promulgated thereunder. Beneficial owners and Insiders should consult with their own legal counsel concerning their obligations under Sections 13 and 16 of the 1934 Act and existing guidance provided by the SEC staff.

In accordance with the Trust's current Agreement and Declaration of Trust (the "Declaration of Trust"), the Board may, without shareholder approval (unless such shareholder approval is required by applicable law, including the 1940 Act), authorize certain funds to merge, reorganize, consolidate, sell all or substantially all of their assets, or take other similar actions with, to or into another fund. The Trust or a fund may be terminated by a majority vote of the Board. Although the shares are not automatically redeemable upon the occurrence of any specific event, the Declaration of Trust provides that the Board will have the unrestricted power to alter the number of shares in a Creation Unit. Therefore, in the event of a termination of the Trust or a fund, the Board, in its sole discretion, could determine to permit the shares to be redeemable in aggregations smaller than Creation Units or to be individually redeemable. In such circumstance, the Trust or a fund may make redemptions, for cash or for a combination of cash and securities. Further, in the event of a termination of the Trust or a fund, the Trust or a fund might elect to pay cash redemptions to all shareholders, with an in-kindelection for shareholders owning in excess of a certain stated minimum amount.

DTC as Securities Depository for Shares of the Fund.Shares of the Fund are represented by securities registered in the name of DTC or its nominee and deposited with, or on behalf of, DTC.

DTC was created in 1973 to enable electronic movement of securities between its participants ("DTC Participants"), and NSCC was established in 1976 to provide a single settlement system for securities clearing and to serve as central counterparty for securities trades among DTC Participants. In 1999, DTC and NSCC were consolidated within The Depository Trust & Clearing Corporation ("DTCC") and became wholly-owned subsidiaries of DTCC. The common stock of DTCC is owned by the DTC Participants, but NYSE and FINRA, through subsidiaries, hold preferred shares in DTCC that provide them with the right to elect one member each to the DTCC board of directors. Access to the DTC

91

system is available to entities, such as banks, brokers, dealers and trust companies, that clear through or maintain a custodial relationship with a DTC Participant, either directly or indirectly ("Indirect Participants").

Beneficial ownership of shares is limited to DTC Participants, Indirect Participants and persons holding interests through DTC Participants and Indirect Participants. Ownership of beneficial interests in shares (owners of such beneficial interests are referred to herein as "Beneficial Owners") is shown on, and the transfer of ownership is effected only through, records maintained by DTC (with respect to DTC Participants) and on the records of DTC Participants (with respect to Indirect Participants and Beneficial Owners that are not DTC Participants). Beneficial Owners will receive from or through the DTC Participant a written confirmation relating to their purchase of shares. The laws of some jurisdictions may require that certain purchasers of securities take physical delivery of such securities in definitive form. Such laws may impair the ability of certain investors to acquire beneficial interests in shares of the Fund.

Conveyance of all notices, statements and other communications to Beneficial Owners is effected as follows. Pursuant to the Depositary Agreement between the Trust and DTC, DTC is required to make available to the Trust upon request and for a fee to be charged to the Trust a listing of the shares of the Fund held by each DTC Participant. The Trust shall inquire of each such DTC Participant as to the number of Beneficial Owners holding shares, directly or indirectly, through such DTC Participant. The Trust shall provide each such DTC Participant with copies of such notice, statement or other communication, in such form, number and at such place as such DTC Participant may reasonably request, in order that such notice, statement or communication may be transmitted by such DTC Participant, directly or indirectly, to such Beneficial Owners. In addition, the Trust shall pay to each such DTC Participant a fair and reasonable amount as reimbursement for the expenses attendant to such transmittal, all subject to applicable statutory and regulatory requirements.

Share distributions shall be made to DTC or its nominee, Cede & Co., as the registered holder of all shares of the Trust. DTC or its nominee, upon receipt of any such distributions, shall credit immediately DTC Participants' accounts with payments in amounts proportionate to their respective beneficial interests in shares of the Fund as shown on the records of DTC or its nominee. Payments by DTC Participants to Indirect Participants and Beneficial Owners of shares held through such DTC Participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in a "street name," and will be the responsibility of such DTC Participants.

The Trust has no responsibility or liability for any aspect of the records relating to or notices to Beneficial Owners, or payments made on account of beneficial ownership interests in such shares, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests, or for any other aspect of the relationship between DTC and the DTC Participants or the relationship between such DTC Participants and the Indirect Participants and Beneficial Owners owning through such DTC Participants. DTC may decide to discontinue providing its service with respect to shares of the Trust at any time by giving reasonable notice to the Trust and discharging its responsibilities with respect thereto under applicable law. Under such circumstances, the Trust shall take action to find a replacement for DTC to perform its functions at a comparable cost.

Distribution of Shares.In connection with the Fund's launch, the Fund will be seeded through the sale of one or more Creation Units by the Fund to one or more initial investors. Initial investors participating in the seeding may be Authorized Participants, a lead market maker or other third party investor or an affiliate of the Fund or the Fund's adviser. Each such initial investor may sell some or all of the shares underlying the Creation Unit(s) held by them pursuant to the registration statement for the Fund (each, a "Selling Shareholder"), which shares have been registered to permit the resale from time to time after purchase. The Fund will not receive any of the proceeds from the resale by the Selling Shareholders of these shares.

92

Selling Shareholders may sell shares owned by them directly or through broker-dealers, in accordance with applicable law, on any national securities exchange on which the shares may be listed or quoted at the time of sale, through trading systems, in the OTC market or in transactions other than on these exchanges or systems at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. These sales may be effected through brokerage transactions, privately negotiated trades, block sales, entry into options or other derivatives transactions or through any other means authorized by applicable law. Selling Shareholders may redeem the shares held in Creation Unit size by them through an Authorized Participant.

Any Selling Shareholder and any broker-dealer or agents participating in the distribution of shares may be deemed to be "underwriters" within the meaning of Section 2(a)(11) of the 1933 Act, in connection with such sales.

Any Selling Shareholder and any other person participating in such distribution will be subject to applicable provisions of the 1934 Act and the rules and regulations thereunder.

Creation and Redemption of Creation Units

General.The Trust issues and sells shares of the Fund only in Creation Units on a continuous basis through the Distributor or its agent, without a sales load, at a price based on the Fund's NAV next determined after receipt, on any Business Day (as defined below), of an order received by the Distributor or its agent in proper form. On days when the Listing Exchange or the bond markets close earlier than normal, the Fund may require orders to be placed earlier in the day. The following table sets forth the number of shares of the Fund that constitute a Creation Unit for the Fund and the approximate value of such Creation Unit as of October 31, 2023:

In its discretion, the Trust reserves the right to increase or decrease the number of the Fund's shares that constitute a Creation Unit. The Board reserves the right to declare a split or a consolidation in the number of shares outstanding of the Fund, and to make a corresponding change in the number of shares constituting a Creation Unit, in the event that the per share price in the secondary market rises (or declines) to an amount that falls outside the range deemed desirable by the Board.

A "Business Day" with respect to the Fund is any day the Fund is open for business, including any day when it satisfies redemption requests as required by Section 22(e) of the 1940 Act. The Fund is open for business any day on which the Listing Exchange on which the Fund is listed for trading is open for business. As of the date of this SAI, the Listing Exchange observes the following holidays, as observed: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Juneteenth, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

Fund Deposit.The consideration for purchase of Creation Units of the Fund is generally cash. However, in some cases the consideration consists of a designated portfolio of securities, assets or

93

other positions (including any portion of such securities for which cash may be substituted) ("Deposit Securities" or "Creation Basket") and the Cash Component computed as described below. Together, the Deposit Securities and the Cash Component constitute the "Fund Deposit," which will be applicable (subject to possible amendment or correction) to creation requests received in proper form. The Fund Deposit represents the minimum initial and subsequent investment amount for a Creation Unit of the Fund. Such Fund Deposit is applicable, subject to any adjustments as described below, to purchases of Creation Units of shares of a given Fund until such time as the next-announced Fund Deposit is made available.

The "Cash Component" is an amount equal to the difference between the NAV of the shares (per Creation Unit) and the "Deposit Amount," which is an amount equal to the market value of the Deposit Securities, and serves to compensate for any differences between the NAV per Creation Unit and the Deposit Amount. Payment of any stamp duty or other similar fees and expenses payable upon transfer of beneficial ownership of the Deposit Securities are the sole responsibility of the Authorized Participant purchasing the Creation Unit.

The Fund's current policy is to accept cash in substitution for the Deposit Securities it might otherwise accept as in-kindconsideration for the purchase of Creation Units. The Fund may, at times, elect to receive Deposit Securities (i.e., the in-kinddeposit of a designated portfolio of securities) and a Cash Component as consideration for the purchase of Creation Units. If the Fund elects to accept Deposit Securities, a purchaser's delivery of the Deposit Securities together with the Cash Component will constitute the "Fund Deposit," which will represent the consideration for a Creation Unit of the Fund. Please see the Cash Purchase Methodsection below and the following discussion summarizing the Deposit Security method for further information on purchasing Creation Units of the Fund.

The identity and number or par value of the Deposit Securities change pursuant to changes in the composition of the Fund's portfolio and as rebalancing adjustments and corporate action events are reflected from time to time by BFA with a view to the investment objective(s) of the Fund. The composition of the Deposit Securities may also change in response to adjustments to the weighting or composition of the component securities constituting the Fund's portfolio.

The Fund Deposit may also be modified to minimize the Cash Component by redistributing the cash to the Deposit Securities portion of the Fund Deposit through "systematic rounding." The rounding methodology "rounds up" position sizes of securities in the Deposit Securities (which in turn reduces the cash portion). However, the methodology limits the maximum allowed percentage change in weight and share quantity of any given security in the Fund Deposit.

The Trust may, in its sole discretion, substitute a "cash in lieu" amount to be added to the Cash Component to replace any Deposit Security in certain circumstances, including: (i) when instruments are not available in sufficient quantity for delivery; (ii) when instruments are not eligible for transfer through DTC or the clearing process (as discussed below); (iii) when instruments that the Authorized Participant (or an investor on whose behalf the Authorized Participant is acting) are not able to be traded due to a trading restriction; (iv) when delivery of the Deposit Security by the Authorized Participant (or by an investor on whose behalf the Authorized Participant is acting) would be restricted under applicable securities or other local laws; (v) in connection with distribution payments to be made by the Fund; or (vi) in certain other situations.

Cash Purchase Method. Although the Trust does not generally permit partial or full cash purchases of Creation Units of its funds, when partial or full cash purchases of Creation Units are available or specified (Creation Units of the Fund are generally offered solely for cash), they will be effected in essentially the same manner as in-kindpurchases thereof. In the case of a partial or full cash purchase, the Authorized Participant must pay the cash equivalent of the Deposit Securities it would otherwise be required to provide through an in-kindpurchase, plus the same Cash Component required to be paid by an in-kindpurchaser.

94

Procedures for Creation of Creation Units.To be eligible to place orders with the Distributor and to create a Creation Unit of the Fund, an entity must be: (i) a "Participating Party,"i.e., a broker-dealer or other participant in the clearing process through the Continuous Net Settlement System of the NSCC (the "Clearing Process"), a clearing agency that is registered with the SEC, or (ii) a DTC Participant, and must have executed an agreement with the Distributor, with respect to creations and redemptions of Creation Units ("Authorized Participant Agreement") (discussed below). A member or participant of a clearing agency registered with the SEC which has a written agreement with the Fund or one of its service providers that allows such member or participant to place orders for the purchase and redemption of Creation Units is referred to as an "Authorized Participant." All shares of the Fund, however created, will be entered on the records of DTC in the name of Cede & Co. for the account of a DTC Participant.

Role of the Authorized Participant.Creation Units may be purchased only by or through a member or participant of a clearing agency registered with the SEC, which has a written agreement with the Fund or one of their service providers that allows such member or participant to place orders for the purchase and redemption of Creation Units. Such Authorized Participant will agree, pursuant to the terms of such Authorized Participant Agreement and on behalf of itself or any investor on whose behalf it will act, to certain conditions, including that such Authorized Participant will make available in advance of each purchase of shares an amount of cash sufficient to pay the Cash Component, once the net asset value of a Creation Unit is next determined after receipt of the purchase order in proper form, together with the transaction fees described below. An Authorized Participant, acting on behalf of an investor, may require the investor to enter into an agreement with such Authorized Participant with respect to certain matters, including payment of the Cash Component. Investors who are not Authorized Participants must make appropriate arrangements with an Authorized Participant. Investors should be aware that their particular broker may not be a DTC Participant or may not have executed an Authorized Participant Agreement and that orders to purchase Creation Units may have to be placed by the investor's broker through an Authorized Participant. As a result, purchase orders placed through an Authorized Participant may result in additional charges to such investor. The Trust does not expect to enter into an Authorized Participant Agreement with more than a small number of DTC Participants. A list of current Authorized Participants may be obtained from the Distributor. The Distributor has adopted guidelines regarding Authorized Participants' transactions in Creation Units that are made available to all Authorized Participants. These guidelines set forth the processes and standards for Authorized Participants to transact with the Distributor and its agents in connection with creation and redemption transactions. In addition, the Distributor may be appointed as the proxy of the Authorized Participant and may be granted a power of attorney under its Authorized Participant Agreement.

Placement of Creation Orders.Fund Deposits must be delivered through the Federal Reserve System (for cash and U.S. government securities), through DTC (for corporate and municipal securities) or through a central depository account, such as with Euroclear or DTC, maintained by State Street or a sub-custodian (a "Central Depository Account"). Any portion of a Fund Deposit that may not be delivered through the Federal Reserve System or DTC must be delivered through a Central Depository Account. The Fund Deposit transfers made through DTC must be ordered by the DTC Participant in a timely fashion so as to ensure the delivery of the requisite number of Deposit Securities through DTC to the account of the Funds generally before 3:00 p.m., Eastern time on the Settlement Date. Fund Deposit transfers made through the Federal Reserve System must be deposited by the participant institution in a timely fashion so as to ensure the delivery of the requisite number or amount of Deposit Securities or cash through the Federal Reserve System to the account of the Funds generally before 3:00 p.m., Eastern time on the Settlement Date. Fund Deposit transfers made through a Central Depository Account must be completed pursuant to the requirements established by the Custodian or sub-custodian for such Central Depository Account generally before 2:00 p.m., Eastern time on the Settlement Date. The "Settlement Date" for all funds is generally the first business day after the Transmittal Date. All questions as to the number of Deposit Securities to be delivered, and the

95

validity, form and eligibility (including time of receipt) for the deposit of any tendered securities, will be determined by the Trust, whose determination shall be final and binding. The amount of cash equal to the Cash Component must be transferred directly to State Street through the Federal Reserve Bank wire transfer system in a timely manner so as to be received by State Street generally before 3:00 p.m., Eastern time on the Settlement Date. If the Cash Component and the Deposit Securities are not received by 3:00 p.m., Eastern time on the Settlement Date, the creation order may be canceled. Upon written notice to the Distributor, such canceled order may be resubmitted the following Business Day using the Fund Deposit as newly constituted to reflect the then current NAV of the Funds. The delivery of Creation Units so created generally will occur no later than the first Business Day following the day on which the purchase order is deemed received by the Distributor, provided that the relevant Fund Deposit has been received by the Funds prior to such time.

Purchase Orders.To initiate an order for a Creation Unit, an Authorized Participant must submit to the Distributor or its agent an irrevocable order to purchase shares of the Fund, in proper form, generally before 4:00 p.m., Eastern time on any Business Day to receive that day's NAV. The Distributor or its agent will notify BFA and the custodian of such order. The custodian will then provide such information to any appropriate sub-custodian.Procedures and requirements governing the delivery of the Fund Deposit are set forth in the procedures handbook for Authorized Participants and may change from time to time. Investors, other than Authorized Participants, are responsible for making arrangements for a creation request to be made through an Authorized Participant. The Distributor or its agent will provide a list of current Authorized Participants upon request. Those placing orders to purchase Creation Units through an Authorized Participant should allow sufficient time to permit proper submission of the purchase order to the Distributor or its agent by the Cutoff Time (as defined below) on such Business Day.

The Authorized Participant must also make available on or before the contractual settlement date, by means satisfactory to the Fund, immediately available or same day funds estimated by the Fund to be sufficient to pay the Cash Component next determined after acceptance of the purchase order, together with the applicable purchase transaction fees. Those placing orders should ascertain the applicable deadline for cash transfers by contacting the operations department of the broker or depositary institution effectuating the transfer of the Cash Component. This deadline is likely to be significantly earlier than the Cutoff Time of the Fund. Investors should be aware that an Authorized Participant may require orders for purchases of shares placed with it to be in the particular form required by the individual Authorized Participant.

The Authorized Participant is responsible for any and all expenses and costs incurred by the Fund, including any applicable cash amounts, in connection with any purchase order.

Timing of Submission of Purchase Orders.An Authorized Participant must submit an irrevocable order to purchase shares of the Fund generally before 4:00 p.m., Eastern time on any Business Day in order to receive that day's NAV. Creation Orders must be transmitted by an Authorized Participant in the form required by the Fund to the Distributor or its agent pursuant to procedures set forth in the Authorized Participant Agreement. Economic or market disruptions or changes, or telephone or other communication failure, may impede the ability to reach the Distributor or its agent or an Authorized Participant. Orders to create shares of the Fund that are submitted on the Business Day immediately preceding a holiday or a day (other than a weekend) when the equity markets in the relevant non-U.S.market are closed may not be accepted. The Fund's deadline specified above for the submission of purchase orders is referred to as the Fund's "Cutoff Time." The Distributor or its agent, in their discretion, may permit the submission of such orders and requests by or through an Authorized Participant at any time (including on days on which a Listing Exchange is not open for business) via communication through the facilities of the Distributor's or its agent's proprietary website maintained for this purpose. Purchase orders and redemption requests, if accepted by the Trust, will be processed based on the NAV next determined after such acceptance in accordance with the Fund's Cutoff Times as provided in the Authorized Participant Agreement and disclosed in this SAI.

96

Acceptance of Orders for Creation Units.Subject to the conditions that (i) an irrevocable purchase order has been submitted by the Authorized Participant (either on its own or another investor's behalf) and (ii) arrangements satisfactory to the Fund are in place for payment of the Cash Component and any other cash amounts which may be due, the Fund will accept the order, subject to the Fund's right (and the right of the Distributor and BFA) to reject any order until acceptance, as set forth below.

Once the Fund has accepted an order, upon the next determination of the net asset value of the shares, the Fund will confirm the issuance of a Creation Unit, against receipt of payment, at such net asset value. The Distributor or its agent will then transmit a confirmation of acceptance to the Authorized Participant that placed the order.

The Fund reserves the right to reject or revoke a creation order transmitted to it by the Distributor or its agent provided that a rejection or revocation of a creation order does not violate Rule 6c-11 under the Investment Company Act. For example, the Fund may reject or revoke a creation order transmitted to it by the Distribution or its agent if (i) the order is not in proper form; (ii) the investor(s), upon obtaining the shares ordered, would own 80% or more of the currently outstanding shares of the Fund; (iii) the Deposit Securities delivered do not conform to the identity and number of shares specified, as described above; (iv) acceptance of the Deposit Securities is not legally required or would, in the opinion of counsel, be unlawful or have an adverse effect on the Fund or its shareholder (e.g.,jeopardize the Fund's tax status); or (v) circumstances outside the control of the Fund, the Distributor or its agent and BFA make it impracticable to process purchase orders. The Distributor or its agent shall notify a prospective purchaser of a Creation Unit and/or the Authorized Participant acting on behalf of such purchaser of its rejection of such order. The Fund, State Street, the sub-custodianand the Distributor or its agent are under no duty, however, to give notification of any defects or irregularities in the delivery of Fund Deposits nor shall any of them incur any liability for failure to give such notification.

Issuance of a Creation Unit.Except as provided herein, a Creation Unit will not be issued until the transfer of good title to the Fund of the Deposit Securities and the payment of the Cash Component have been completed. When the sub-custodian has confirmed to the custodian that the securities included in the Fund Deposit (or the cash value thereof) have been delivered to the account of the relevant sub-custodian or sub-custodians, the Distributor or its agent and BFA shall be notified of such delivery and the Fund will issue and cause the delivery of the Creation Unit. Creation Units are generally issued on a "T+1 basis" (i.e., one Business Days after trade date). The Fund reserves the right to settle Creation Unit transactions on a basis other than T+1, as applicable. For example, the Fund reserves the right to settle Creation Unit transactions on a basis other than T+1 in order to accommodate non-U.S. market holiday schedules, the occurrence of a holiday in the U.S. bond market that is not a holiday observed in the U.S. equity market, to account for different treatment among non-U.S. and U.S. markets of dividend record dates and dividend ex-dates (i.e., the last date the holder of a security can sell the security and still receive dividends payable on the security sold) and in certain other circumstances consistent with applicable law.

To the extent contemplated by an Authorized Participant Agreement with the Distributor, the Fund will issue Creation Units to such Authorized Participant, notwithstanding the fact that the corresponding Fund Deposits have not been received in part or in whole, in reliance on the undertaking of the Authorized Participant to deliver the missing Deposit Securities as soon as possible, which undertaking shall be secured by such Authorized Participant's delivery and maintenance of collateral as set forth in the handbook for Authorized Participants. The Trust may use such collateral at any time to buy Deposit Securities for the Fund. Such collateral must be delivered no later than the time specified by the Fund or its custodian on the contractual settlement date. Information concerning the Fund's current procedures for collateralization of missing Deposit Securities is available from the Distributor or its agent. The Authorized Participant Agreement will permit the Fund to buy the missing Deposit Securities at any time

97

and will subject the Authorized Participant to liability for any shortfall between the cost to the Fund of purchasing such securities and the collateral including, without limitation, liability for related brokerage, borrowings and other charges.

In certain cases, Authorized Participants may create and redeem Creation Units on the same trade date and in these instances, the Fund reserves the right to settle these transactions on a net basis or require a representation from the Authorized Participants that the creation and redemption transactions are for separate beneficial owners. All questions as to the number of shares of each security in the Deposit Securities and the validity, form, eligibility and acceptance for deposit of any securities to be delivered shall be determined by the Fund and the Fund's determination shall be final and binding.

Costs Associated with Creation Transactions.A standard creation transaction fee is imposed to offset the transfer and other transaction costs associated with the issuance of Creation Units. Under an ETF Services Agreement, the Fund has retained BRIL, an affiliate of BFA, to perform certain ETF Services. BRIL will receive from an Authorized Participant a standard transaction fee on each creation order, which consists of (1) a fee for providing the ETF Services (the "ETF Servicing Fee") and (2) transfer, processing and other transaction costs charged by the Fund custodian in connection with the issuance of Creation Units for such creation order ("Custody Transaction Costs"). BRIL is entitled to retain the ETF Servicing Fee pursuant to the ETF Services Agreement, but BRIL will reimburse any Custody Transaction Costs to the Fund custodian according to the amounts invoiced by such custodian.

The ETF Servicing Fee is a flat fee per order regardless of the number of Creation Units being purchased, which amount will vary among different BlackRock-advised funds based on a number of factors, including the complexity of the order and the types of securities or instruments included in a fund's Creation Basket, among other variables. The actual Custody Transaction Costs vary per order based on the number of trades, underlying markets and settlement locations associated with the issuance of a Creation Unit. The following table sets forth an estimate of the creation transaction fee for a Creation Unit based on data as of November 13, 2023. The actual fee charged to an Authorized Participant in connection with a creation order will vary over time depending on the factors discussed above, and may be higher than the fee set forth below.

If a purchase consists solely or partially of cash, the Authorized Participant may also be required to cover (up to the maximum amount shown below) certain brokerage, tax, foreign exchange, execution, price movement and other costs and expenses related to the execution of trades resulting from such transaction (which may, in certain instances, be based on a good faith estimate of transaction costs). Authorized Participants will also bear the costs of transferring the Deposit Securities to the Fund. Certain fees/costs associated with creation transactions may be waived in certain circumstances. Investors who use the services of a broker or other financial intermediary to acquire Fund shares may be charged a fee for such services.

The following table sets forth the Fund's estimated creation transaction fee based on data as of November 13, 2023 and maximum additional charge (as described above):

98

Redemption of Creation Units.Shares of the Fund may be redeemed by Authorized Participants only in Creation Units at their NAV next determined after receipt of a redemption request in proper form by the Distributor or its agent and only on a Business Day. The Fund will not redeem shares in amounts less than Creation Units. There can be no assurance, however, that there will be sufficient liquidity in the secondary market at any time to permit assembly of a Creation Unit. Investors should expect to incur brokerage and other costs in connection with assembling a sufficient number of shares to constitute a Creation Unit that could be redeemed by an Authorized Participant. Beneficial owners also may sell shares in the secondary market.

The Fund generally redeems Creation Units solely for cash. However, the Fund reserves the right to distribute securities in-kindas payment for Creation Units being redeemed at any time. For example, the Fund may determine to offer in-kindredemptions instead of cash redemptions in response to changing market conditions or during periods of volatility. The Fund is permitted to offer either cash or in-kindredemptions, which may vary throughout the trading day, in the discretion of the Fund. Please see the Cash Redemption Methodsection below and the following discussion summarizing the in-kindmethod for further information on redeeming Creation Units of the Fund.

The Fund publishes the designated portfolio of securities (including any portion of such securities for which cash may be substituted) that will be applicable to redemption requests received in proper form (as defined below) on that day ("Fund Securities" or "Redemption Basket"), and an amount of cash (the "Cash Amount," as described below) are applicable, in order to effect redemptions of Creation Units of the Fund. Such Fund Securities and Cash Amount will remain in effect until such time as the next announced composition of the Fund Securities and Cash Amount is made available. The Fund Securities and Cash Amount are subject to possible amendment or correction.

Procedures and requirements governing redemption transactions are set forth in the handbook for Authorized Participants and may change from time to time.

Unless cash redemptions are available or specified for the Fund, the redemption proceeds for a Creation Unit generally consist of Fund Securities, plus the Cash Amount, which is an amount equal to the difference between the net asset value of the shares being redeemed, as next determined after the receipt of a redemption request in proper form, and the value of Fund Securities, less a redemption transaction fee (as described below).

The Trust may, in its sole discretion, substitute a "cash in lieu" amount to replace any Fund Security in certain circumstances, including: (i) when the delivery of a Fund Security to the Authorized Participant (or to an investor on whose behalf the Authorized Participant is acting) would be restricted under applicable securities or other local laws or due to a trading restriction; (ii) when the delivery of a Fund Security to the Authorized Participant would result in the disposition of the Fund Security by the Authorized Participant due to restrictions under applicable securities or other local laws; (iii) when the delivery of a Fund Security to the Authorized Participant would result in unfavorable tax treatment; (iv) when a Fund Security cannot be settled or otherwise delivered in time to facilitate an in-kindredemption; or (v) in certain other situations. The amount of cash paid out in such cases will be equivalent to the value of the substituted security listed as a Fund Security. The amount of cash paid out in such cases will be equivalent to the value of the substituted security listed as a Fund Security. In the event that the Fund Securities have a value greater than the NAV of the shares, a compensating cash payment equal to the difference is required to be made by or through an Authorized Participant by the redeeming shareholder. The Fund generally redeems Creation Units for cash and/or in-kind.The Redemption Basket may also be modified to minimize the Cash Component by redistributing the cash to the Fund Securities portion of the Redemption Basket through systematically rounding. The rounding methodology allows position sizes of securities in the Fund Securities to be "rounded up," while limiting the maximum allowed percentage change in weight and share quantity of any given

99

security in the Redemption Basket. Redemption Baskets may also be modified to position a fund towards a forward index rebalance to reflect revisions that account for index additions, deletions, and re-weights.

Cash Redemption Method.Partial or full cash redemptions will be effected in essentially the same manner as in-kindredemptions thereof. In the case of partial or full cash redemption, the Authorized Participant receives the cash equivalent of the Fund Securities it would otherwise receive through an in-kindredemption, plus the same Cash Amount to be paid to an in-kindredeemer.

Costs Associated with Redemption Transactions. A standard redemption transaction fee is imposed to offset transfer and other transaction costs that may be incurred by the Fund. As described above, under an ETF Services Agreement, the Fund has retained BRIL, an affiliate of BFA, to perform certain ETF Services. BRIL will receive from an Authorized Participant a standard transaction fee on each redemption order, which consists of (1) the ETF Servicing Fee and (2) Custody Transaction Costs. BRIL is entitled to retain the ETF Servicing Fee pursuant to the ETF Services Agreement, but BRIL will reimburse any Custody Transaction Costs to the Fund custodian according to the amounts invoiced by such custodian.

The ETF Servicing Fee is a flat fee per order regardless of the number of Creation Units being redeemed, which amount will vary among different BlackRock-advised funds based on a number of factors, including the complexity of the order and the types of securities or instruments included in a fund's Redemption Basket, among other variables. The actual Custody Transaction Costs vary per order based on the number of trades, underlying markets, and settlement locations associated with the redemption of a Creation Unit. The following table sets forth an estimate of the redemption transaction fee for a Creation Unit based on data as of November 13, 2023. The actual fee charged to an Authorized Participant in connection with a redemption order will vary over time depending on the factors discussed above, and may be higher than the fee set forth below.

If a redemption consists solely or partially of cash, the Authorized Participant may also be required to cover (up to the maximum amount shown below) certain brokerage, tax, foreign exchange, execution, price movement and other costs and expenses related to the execution of trades resulting from such transaction (which may, in certain instances, be based on a good faith estimate of transaction costs). Authorized Participants will also bear the costs of transferring the Fund Securities from the Fund to their account on their order. Certain fees/costs associated with redemption transactions may be waived in certain circumstances. Investors who use the services of a broker or other financial intermediary to dispose of Fund shares may be charged a fee for such services.

The following table sets forth the Fund's estimated redemption transaction fee based on data as of November 13, 2023 and maximum additional charge (as described above):

Placement of Redemption Orders.Redemption requests for Creation Units of the Fund must be submitted to the Distributor or its agent by or through an Authorized Participant. An Authorized Participant must submit an irrevocable request to redeem shares of the Fund generally before

100

4:00 p.m., Eastern time on any Business Day,in order to receive that day's NAV. On days when the Listing Exchange closes earlier than normal, the Fund may require orders to redeem Creation Units to be placed earlier that day. Investors, other than Authorized Participants, are responsible for making arrangements for a redemption request to be made through an Authorized Participant. The Distributor or its agent will provide a list of current Authorized Participants upon request.

The Authorized Participant must transmit the request for redemption in the form required by the Fund to the Distributor or its agent in accordance with procedures set forth in the Authorized Participant Agreement. Investors should be aware that their particular broker may not have executed an Authorized Participant Agreement and that, therefore, requests to redeem Creation Units may have to be placed by the investor's broker through an Authorized Participant who has executed an Authorized Participant Agreement. At any time, only a limited number of broker-dealers will have an Authorized Participant Agreement in effect. Investors making a redemption request should be aware that such request must be in the form specified by such Authorized Participant. Investors making a request to redeem Creation Units should allow sufficient time to permit proper submission of the request by an Authorized Participant and transfer of the shares to the Fund's transfer agent; such investors should allow for the additional time that may be required to effect redemptions through their banks, brokers or other financial intermediaries if such intermediaries are not Authorized Participants.

A redemption request is considered to be in "proper form" if: (i) an Authorized Participant has transferred or caused to be transferred to the Fund's transfer agent the Creation Unit redeemed through the book-entry system of DTC so as to be effective by the Listing Exchange closing time on any Business Day on which the redemption request is submitted; (ii) a request in form satisfactory to the Fund is received by the Distributor or its agent from the Authorized Participant on behalf of itself or another redeeming investor within the time periods specified above; and (iii) all other procedures set forth in the Authorized Participant Agreement are properly followed.

Upon receiving a redemption request, the Distributor or its agent shall notify the Fund and the Fund's transfer agent of such redemption request. The tender of an investor's shares for redemption and the distribution of the securities and/or cash included in the redemption payment made in respect of Creation Units redeemed will be made through DTC and the relevant Authorized Participant to the Beneficial Owner thereof as recorded on the book-entry system of DTC or the DTC Participant through which such investor holds, as the case may be, or by such other means specified by the Authorized Participant submitting the redemption request.

A redeeming Authorized Participant, whether on its own account or acting on behalf of a Beneficial Owner, must maintain appropriate security arrangements with a qualified broker-dealer, bank or other custody providers in each jurisdiction in which any of the portfolio securities are customarily traded, to which account such portfolio securities will be delivered.

Deliveries of redemption proceeds by the Fund are generally made within two Business Days (i.e.,"T+2"). However, the Fund reserves the right to settle redemption transactions on a basis other than T+2, including a shorter settlement period, if necessary or appropriate under the circumstances and compliant with applicable law. Delayed settlement may occur due to a number of different reasons, including, without limitation, settlement cycles for the underlying securities, unscheduled market closings, an effort to link distribution to dividend record dates and ex-dates and newly announced holidays. For example, the redemption settlement process may be extended beyond T+2 because of the occurrence of a holiday in a non-U.S. market or in the U.S. bond market that is not a holiday observed in the U.S. equity market.

If the Fund includes a foreign investment in its basket, and if a local market holiday, or series of consecutive holidays, or the extended delivery cycles for transferring foreign investments to redeeming

101

Authorized Participants prevents timely delivery of the foreign investment in response to a redemption request, the Fund may delay delivery of the foreign investment more than seven days if the Fund delivers the foreign investment as soon as practicable, but in no event later than 15 days.

If neither the Authorized Participant nor the Beneficial Owner on whose behalf the Authorized Participant is acting has appropriate arrangements to take delivery of Fund Securities in the applicable non-U.S. jurisdiction and it is not possible to make other such arrangements, or if it is not possible to effect deliveries of Fund Securities in such jurisdiction, the Fund may in its discretion exercise its option to redeem such shares in cash, and the Beneficial Owner will be required to receive its redemption proceeds in cash. In such case, the investor will receive a cash payment equal to the net asset value of its shares based on the NAV of the Fund next determined after the redemption request is received in proper form (minus a redemption transaction fee and additional charges specified above to offset the Fund's brokerage and other transaction costs associated with the disposition of Fund Securities). Redemptions of shares for Fund Securities will be subject to compliance with applicable U.S. federal and state securities laws and the Fund (whether or not it otherwise permits cash redemptions) reserves the right to redeem Creation Units for cash to the extent that the Fund cannot lawfully deliver specific Fund Securities upon redemptions or cannot do so without first registering the Fund Securities under such laws.

Proceeds of a redemption request will be paid to the Authorized Participant redeeming shares as soon as practicable after the date of redemption (within seven calendar days thereafter).

To the extent contemplated by an Authorized Participant's agreement with the Distributor or its agent, in the event an Authorized Participant has submitted a redemption request in proper form but is unable to transfer all or part of the Creation Unit to be redeemed to the Fund, at or prior to the time specified by the Fund or its custodian on the Business Day after the date of submission of such redemption request, the Distributor or its agent will accept the redemption request in reliance on the undertaking by the Authorized Participant to deliver the missing shares as soon as possible. Such undertaking shall be secured by the Authorized Participant's delivery and maintenance of collateral as set forth in the handbook for Authorized Participants. Such collateral must be delivered no later than the time specified by the Fund or its custodian on the Business Day after the date of submission of such redemption request and shall be held by State Street and marked-to-marketdaily. The fees of State Street and any sub-custodiansin respect of the delivery, maintenance and redelivery of the collateral shall be payable by the Authorized Participant. The Authorized Participant Agreement permits the Fund to acquire shares of the Fund at any time and subjects the Authorized Participant to liability for any shortfall between the aggregate of the cost to the Fund of purchasing such shares, plus the value of the Cash Amount, and the value of the collateral together with liability for related brokerage and other charges.

Because the portfolio securities of the Fund may trade on exchange(s) on days that a Listing Exchange is closed or are otherwise not Business Days for the Fund, shareholders may not be able to redeem their shares of the Fund, or purchase or sell shares of the Fund on the Listing Exchange on days when the NAV of the Fund could be significantly affected by events in the relevant non-U.S.markets.

The right of redemption may be suspended or the date of payment postponed with respect to the Fund: (i) for any period during which a Listing Exchange is closed (other than customary weekend and holiday closings); (ii) for any period during which trading on a Listing Exchange is suspended or restricted; (iii) for any period during which an emergency exists as a result of which disposal of the shares of the Fund's portfolio securities or determination of its net asset value is not reasonably practicable; or (iv) in such other circumstance as is permitted by the SEC.

Custom Baskets. Creation and Redemption baskets may differ and the Fund will accept "custom baskets." A custom basket may include any of the following: (i) a basket that is composed of a

102

non-representativeselection of the Fund's portfolio holdings; (ii) a representative basket that is different from the initial basket used in transactions on the same business day; or (iii) a basket that contains bespoke cash substitutions for a single Authorized Participant. The Fund has adopted policies and procedures that govern the construction and acceptance of baskets, including heightened requirements for certain types of custom baskets. Such policies and procedures provide the parameters for the construction and acceptance of custom baskets that are in the best interests of the Fund and its shareholders, establish processes for revisions to, or deviations from, such parameters, and specify the titles and roles of the employees of BFA who are required to review each custom basket for compliance with those parameters. In addition, when constructing custom baskets for redemptions, the tax efficiency of the Fund may be taken into account. The policies and procedures distinguish among different types of custom baskets that may be used and impose different requirements for different types of custom baskets in order to seek to mitigate against potential risks of conflicts and/or overreaching by an Authorized Participant. BlackRock has established a governance process to oversee basket compliance for the Fund, as set forth in the Fund's policies and procedures.

Taxation on Creations and Redemptions of Creation Units. An Authorized Participant generally will recognize either gain or loss upon the exchange of Deposit Securities for Creation Units. This gain or loss is calculated by taking the market value of the Creation Units purchased over the Authorized Participant's aggregate basis in the Deposit Securities exchanged therefor. However, the IRS may apply the wash sales rules to determine that any loss realized upon the exchange of Deposit Securities for Creation Units is not currently deductible. Authorized Participants should consult their own tax advisors.

Current U.S. federal income tax laws dictate that capital gain or loss realized from the redemption of Creation Units will generally create long-term capital gain or loss if the Authorized Participant holds the Creation Units for more than one year, or short-term capital gain or loss if the Creation Units were held for one year or less, if the Creation Units are held as capital assets.

Taxes

The following is a summary of certain material U.S. federal income tax considerations regarding the purchase, ownership and disposition of shares of the Fund. This summary does not address all of the potential U.S. federal income tax consequences that may be applicable to the Fund or to all categories of investors, some of which may be subject to special tax rules. Current and prospective shareholders are urged to consult their own tax advisors with respect to the specific federal, state, local and non-U.S.tax consequences of investing in the Fund. The summary is based on the laws and judicial and administrative interpretations thereof in effect on the date of this SAI, all of which are subject to change, possibly with retroactive effect.

Regulated Investment Company Qualifications. The Fund intends to continue to qualify for and to elect treatment as a separate RIC under Subchapter M of the Internal Revenue Code. To qualify for treatment as a RIC, the Fund must annually distribute at least 90% of its investment company taxable income (which includes dividends, interest and net short-term capital gains) and meet several other requirements. Among such other requirements are the following: (i) at least 90% of the Fund's annual gross income must be derived from dividends, interest, payments with respect to securities loans, gains from the sale or other disposition of stock or securities or non-U.S.currencies, other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies, and net income derived from interests in qualified publicly-traded partnerships (i.e., partnerships that are traded on an established securities

103

market or tradable on a secondary market, other than a partnership that derives at least 90% of its income from interest, dividends, capital gains and other traditionally permitted RIC income); and (ii) at the close of each quarter of the Fund's taxable year, (a) at least 50% of the market value of the Fund's total assets must be represented by cash and cash items, U.S. government securities, securities of other RICs and other securities, with such other securities limited for purposes of this calculation in respect of any one issuer to an amount not greater than 5% of the value of the Fund's assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of the Fund's total assets may be invested in the securities of any one issuer, of two or more issuers of which 20% or more of the voting stock is held by the Fund and that are engaged in the same or similar trades or businesses or related trades or businesses (other than the securities of other RICs) or the securities of one or more qualified publicly-traded partnerships.

The Fund may be able to cure a failure to derive at least 90% of its income from the sources specified above or a failure to diversify its holdings in the manner described above by paying a tax and/or by disposing of certain assets. If, in any taxable year, the Fund fails one of these tests and does not timely cure the failure, that Fund will be taxed in the same manner as an ordinary corporation and distributions to its shareholders will not be deductible by that Fund in computing its taxable income.

Although in general the passive loss rules of the Internal Revenue Code do not apply to RICs, such rules do apply to a RIC with respect to items attributable to an interest in a qualified publicly-traded partnership. The Fund's investments in partnerships, including in qualified publicly-traded partnerships, may result in the Fund being subject to state, local, or non-U.S.income, franchise or withholding tax liabilities.

Taxation of RICs. As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its taxable investment income and capital gains that it distributes to its shareholders, provided that it satisfies a minimum distribution requirement. To satisfy the minimum distribution requirement, the Fund must distribute to its shareholders at least the sum of (i) 90% of its "investment company taxable income" (i.e., income other than its net realized long-term capital gain over its net realized short-term capital loss), plus or minus certain adjustments, and (ii) 90% of its net tax-exemptincome for the taxable year. The Fund will be subject to income tax at regular corporate rates on any taxable income or gains that it does not distribute to its shareholders. If the Fund fails to qualify for any taxable year as a RIC or fails to meet the distribution requirement, all of its taxable income will be subject to tax at regular corporate income tax rates without any deduction for distributions to shareholders, and such distributions generally will be taxable to shareholders as ordinary dividends to the extent of the Fund's current and accumulated earnings and profits. In such event, distributions to individuals should be eligible to be treated as qualified dividend income and distributions to corporate shareholders generally should be eligible for the dividends-received deduction. Although the Fund intends to distribute substantially all of its net investment income and its capital gains for each taxable year, the Fund may decide to retain a portion of its income or gains if the Fund determines that doing so is in the interest of its shareholders. The Fund will be subject to U.S. federal income taxation to the extent any such income or gains are not distributed. Moreover, if the Fund fails to qualify as a RIC in any year, it must pay out its earnings and profits accumulated in that year in order to qualify again as a RIC. If a Fund fails to qualify as a RIC for a period greater than two taxable years, the Fund may be required to recognize any net built-ingains with respect to certain of its assets (i.e., the excess of the aggregate gains, including items of income, over aggregate losses that would have been realized with respect to such assets if the Fund had been liquidated) if it qualifies as a RIC in a subsequent year.

Net Capital Loss Carryforwards.Net capital loss carryforwards may be applied against any net realized capital gains in each succeeding year, until they have been reduced to zero.

104

In the event that the Fund were to experience an ownership change as defined under the Internal Revenue Code, the loss carryforwards and other favorable tax attributes of the Fund, if any, may be subject to limitation.

Excise Tax. The Fund will be subject to a 4% excise tax on certain undistributed income if it does not distribute to its shareholders in each calendar year at least 98% of its ordinary income for the calendar year plus at least 98.2% of its capital gain net income for the 12 months ended October 31 of such year. For this purpose, however, any ordinary income or capital gain net income retained by the Fund that is subject to corporate income tax will be considered to have been distributed by year-end.In addition, the minimum amounts that must be distributed in any year to avoid the excise tax will be increased or decreased to reflect any underdistribution or overdistribution, as the case may be, from the previous year. The Fund intends to declare and distribute dividends and distributions in the amounts and at the times necessary to avoid the application of this 4% excise tax.

Taxation of U.S. Shareholders. Dividends and other distributions by the Fund are generally treated under the Internal Revenue Code as received by the shareholders at the time the dividend or distribution is made. However, any dividend or capital gain distribution declared by the Fund in October, November or December of any calendar year and payable to shareholders of record on a specified date in such a month shall be deemed to have been received by each shareholder on December 31 of such calendar year and to have been paid by the Fund not later than such December 31, provided such dividend is actually paid by the Fund during January of the following calendar year.

The Fund intends to distribute annually to its shareholders substantially all of its net tax-exemptincome, investment company taxable income and any net realized long-term capital gains in excess of net realized short-term capital losses (including any capital loss carryovers). However, if the Fund retains for investment an amount equal to all or a portion of its net long-term capital gains in excess of its net short-term capital losses (including any capital loss carryovers), it will be subject to a corporate tax (at a flat rate of 21%) on the amount retained. In that event, the Fund will report such retained amounts as undistributed capital gains in a notice to its shareholders who (a) will be required to include in income for U.S. federal income tax purposes, as long-term capital gains, their proportionate shares of the undistributed amount, (b) will be entitled to credit their proportionate shares of the tax paid by the Fund on the undistributed amount against their U.S. federal income tax liabilities, if any, and to claim refunds to the extent their credits exceed their liabilities, if any, and (c) will be entitled to increase their tax basis, for U.S. federal income tax purposes, in their shares by an amount equal to the excess of the amount in clause (a) over the amount in clause (b). Organizations or persons not subject to U.S. federal income tax on such capital gains will be entitled to a refund of their pro rata share of such taxes paid by the Fund upon filing appropriate returns or claims for refund with the IRS.

Distributions of net realized long-term capital gains, if any, that the Fund reports as capital gain dividends are taxable as long- term capital gains, whether paid in cash or in shares and regardless of how long a shareholder has held shares of the Fund. All other dividends of the Fund (including dividends from short-term capital gains) from its current and accumulated earnings and profits ("regular dividends") are generally subject to tax as ordinary income. Long-term capital gains are eligible for taxation at a maximum rate of 15% or 20% for non-corporateshareholders, depending on whether their income exceeds certain threshold amounts.

If an individual receives a regular dividend qualifying for the long-term capital gain rates and such dividend constitutes an "extraordinary dividend," and the individual subsequently recognizes a loss on the sale or exchange of stock in respect of which the extraordinary dividend was paid, then the loss will be long-term capital loss to the extent of such extraordinary dividend. An "extraordinary dividend" on common stock for this purpose is generally a dividend (i) in an amount greater than or equal to 10% of

105

the taxpayer's tax basis (or trading value) in a share of stock, aggregating dividends with ex-dividenddates within an 85-dayperiod, or (ii) in an amount greater than 20% of the taxpayer's tax basis (or trading value) in a share of stock, aggregating dividends with ex-dividenddates within a 365-dayperiod.

Distributions in excess of the Fund's current and accumulated earnings and profits will, as to each shareholder, be treated as a tax-freereturn of capital to the extent of a shareholder's basis in shares of the Fund, and as a capital gain thereafter (if the shareholder holds shares of the Fund as capital assets). Distributions in excess of the Fund's minimum distribution requirements, but not in excess of the Fund's earnings and profits, will be taxable to shareholders and will not constitute nontaxable returns of capital. Shareholders receiving dividends or distributions in the form of additional shares should be treated for U.S. federal income tax purposes as receiving a distribution in an amount equal to the amount of money that the shareholders receiving cash dividends or distributions will receive and should have a cost basis in the shares received equal to such amount. No deduction would be allowed to an investor for interest on indebtedness incurred or continued to purchase or carry shares of the Fund to the extent the interest deduction would relate to exempt-interest dividends received.

A 3.8% U.S. federal Medicare contribution tax is imposed on net investment income, including, but not limited to, interest, dividends, and net gain from investments, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Investors considering buying shares just prior to a dividend or capital gain distribution should be aware that, although the price of shares purchased at that time may reflect the amount of the forthcoming distribution, such dividend or distribution may nevertheless be taxable to them. If the Fund is the holder of record of any security on the record date for any dividends payable with respect to such security, such dividends will be included in the Fund's gross income not as of the date received but as of the later of (i) the date such security became ex-dividendwith respect to such dividends (i.e., the date on which a buyer of the security would not be entitled to receive the declared, but unpaid, dividends); or (ii) the date the Fund acquired such security. Accordingly, in order to satisfy its income distribution requirements, the Fund may be required to pay dividends based on anticipated earnings, and shareholders may receive dividends in an earlier year than would otherwise be the case.

In certain situations, the Fund may, for a taxable year, defer all or a portion of its net capital loss (or if there is no net capital loss, then any net long-term or short-term capital loss) realized after October and its late-year ordinary loss (defined as the sum of the excess of post-October foreign currency and passive foreign investment company ("PFIC") losses over post- October foreign currency and PFIC gains, plus the excess of post-December ordinary losses over post-December ordinary income) until the next taxable year in computing its investment company taxable income and net capital gain, which will defer the recognition of such realized losses. Such deferrals and other rules regarding gains and losses realized after October (or December) may affect the tax character of shareholder distributions.

Sales of Shares. Upon the sale or exchange of shares of the Fund, a shareholder will realize a taxable gain or loss equal to the difference between the amount realized and the shareholder's basis in shares of the Fund. A redemption of shares by the Fund will be treated as a sale for this purpose. Such gain or loss will be treated as capital gain or loss if the shares are capital assets in the shareholder's hands and will be long-term capital gain or loss if the shares are held for more than one year and short- term capital gain or loss if the shares are held for one year or less. Any loss realized on a sale or exchange will be disallowed to the extent the shares disposed of are replaced, including replacement through the reinvesting of dividends or capital gains distributions, or by an option, or contract to acquire substantially identical shares, within a 61-dayperiod beginning 30 days before and ending 30 days after the disposition of the shares. In such a case, the basis of the shares acquired will be increased to reflect the disallowed loss. Any loss realized by a shareholder on the sale of Fund shares held by the

106

shareholder for six months or less will be treated for U.S. federal income tax purposes as a long-term capital loss to the extent of any distributions or deemed distributions of long-term capital gains received by the shareholder with respect to such share. The Medicare contribution tax described above will apply to the sale of Fund shares.

If a shareholder incurs a sales charge in acquiring shares of the Fund, disposes of those shares within 90 days and then, on or before January 31 of the following calendar year, acquires shares in a mutual fund for which the otherwise applicable sales charge is reduced by reason of a reinvestment right (e.g., an exchange privilege), the original sales charge will not be taken into account in computing gain/loss on the original shares to the extent the subsequent sales charge is reduced. Instead, the disregarded portion of the original sales charge will be added to the tax basis of the newly acquired shares. Furthermore, the same rule also applies to a disposition of the newly acquired shares made within 90 days of the second acquisition. This provision prevents a shareholder from immediately deducting the sales charge by shifting his or her investment within a family of mutual funds.

Backup Withholding. In certain cases, the Fund will be required to withhold at a 24% rate and remit to the U.S. Treasury such amounts withheld from any distributions paid to a shareholder who: (i) has failed to provide a correct taxpayer identification number; (ii) is subject to backup withholding by the IRS; (iii) has failed to certify to the Fund that such shareholder is not subject to backup withholding; or (iv) has not certified that such shareholder is a U.S. person (including a U.S. resident alien). Backup withholding is not an additional tax and any amount withheld may be credited against a shareholder's U.S. federal income tax liability.

Sections 351 and 362. The Trust, on behalf of the Fund, has the right to reject an order for a purchase of shares of the Fund if the purchaser (or group of purchasers) would, upon obtaining the shares so ordered, own 80% or more of the outstanding shares of a given Fund and if, pursuant to Sections 351 and 362 of the Internal Revenue Code, that Fund would have a basis in the securities different from the market value of such securities on the date of deposit. If the Fund's basis in such securities on the date of deposit was less than market value on such date, the Fund, upon disposition of the securities, would recognize more taxable gain or less taxable loss than if its basis in the securities had been equal to market value. It is not anticipated that the Trust will exercise the right of rejection except in a case where the Trust determines that accepting the order could result in material adverse tax consequences to the Fund or its shareholders. The Trust also has the right to require information necessary to determine beneficial share ownership for purposes of the 80% determination.

Taxation of Certain Derivatives. The Fund's transactions in zero coupon securities, non-U.S.currencies, forward contracts, options and futures contracts (including options and futures contracts on non-U.S.currencies), to the extent permitted, will be subject to special provisions of the Internal Revenue Code (including provisions relating to "hedging transactions" and "straddles") that, among other consequences, may affect the character of gains and losses realized by the Fund (i.e., may affect whether gains or losses are ordinary or capital), accelerate recognition of income to the Fund and defer Fund losses. These rules could therefore affect the character, amount and timing of distributions to shareholders. These provisions also (a) will require the Fund to mark-to-marketcertain types of the positions in its portfolio (i.e., treat them as if they were closed out at the end of each year) and (b) may cause the Fund to recognize income without receiving cash with which to pay dividends or make distributions in amounts necessary to satisfy the distribution requirements for avoiding income and excise taxes. The Fund will monitor its transactions, will make the appropriate tax elections and will make the appropriate entries in its books and records when it acquires any zero coupon security, non-U.S.currency, forward contract, option, futures contract or hedged investment in order to mitigate the effect of these rules and prevent disqualification of the Fund as a RIC.

107

The Fund's investments in so-called"section 1256 contracts," such as regulated futures contracts, most non-U.S.currency forward contracts traded in the interbank market and options on most security indexes, are subject to special tax rules. All section 1256 contracts held by the Fund at the end of its taxable year are required to be marked to their market value, and any unrealized gain or loss on those positions will be included in the Fund's income as if each position had been sold for its fair market value at the end of the taxable year. The resulting gain or loss will be combined with any gain or loss realized by the Fund from positions in section 1256 contracts closed during the taxable year. Provided such positions were held as capital assets and were not part of a "hedging transaction" nor part of a "straddle," 60% of the resulting net gain or loss will be treated as long-term capital gain or loss, and 40% of such net gain or loss will be treated as short-term capital gain or loss, regardless of the period of time the positions were actually held by the Fund.

As a result of entering into swap contracts, the Fund may make or receive periodic net payments. The Fund may also make or receive a payment when a swap is terminated prior to maturity through an assignment of the swap or other closing transaction. Periodic net payments will generally constitute ordinary income or deductions, while termination of a swap will generally result in capital gain or loss (which will be a long-term capital gain or loss if the Fund has been a party to the swap for more than one year). The cost of any payments made by the Fund on a swap transaction will be netted pro rata against both tax exempt and taxable gross income. With respect to certain types of swaps, the Fund may be required to currently recognize income or loss with respect to future payments on such swaps or may elect under certain circumstances to mark such swaps to market annually for tax purposes as ordinary income or loss.

Qualified Dividend Income. Distributions by the Fund of investment company taxable income (including any short-term capital gains), whether received in cash or shares, will be taxable either as ordinary income or as qualified dividend income, which is eligible to be taxed at long-term capital gain rates to the extent the Fund receives qualified dividend income on the securities it holds and the Fund reports the distribution as qualified dividend income. Qualified dividend income is, in general, dividend income from taxable U.S. corporations (but generally not from U.S. REITs) and certain non-U.S.corporations (e.g., non-U.S.corporations that are not PFICs and which are incorporated in a possession of the U.S. or in certain countries with a comprehensive tax treaty with the U.S., or the stock of which is readily tradable on an established securities market in the U.S. (where the dividends are paid with respect to such stock)). Under current IRS guidance, the U.S. has appropriate comprehensive income tax treaties with the following countries: Australia, Austria, Bangladesh, Barbados, Belgium, Bulgaria, Canada, China (but not with Hong Kong, which is treated as a separate jurisdiction for U.S. tax purposes), Cyprus, the Czech Republic, Denmark, Egypt, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, India, Indonesia, Ireland, Israel, Italy, Jamaica, Japan, Kazakhstan, Latvia, Lithuania, Luxembourg, Malta, Mexico, Morocco, the Netherlands, New Zealand, Norway, Pakistan, the Philippines, Poland, Portugal, Romania, Russia, the Slovak Republic, Slovenia, South Africa, South Korea, Spain, Sri Lanka, Sweden, Switzerland, Thailand, Trinidad and Tobago, Tunisia, Turkey, Ukraine, the United Kingdom and Venezuela. Substitute payments received by the Fund for securities lent out by the Fund will not be qualified dividend income.

A dividend from the Fund will not be treated as qualified dividend income to the extent that: (i) the shareholder has not held the shares on which the dividend was paid for 61 days during the 121-dayperiod that begins on the date that is 60 days before the date on which the shares become ex-dividendwith respect to such dividend or the Fund fails to satisfy those holding period requirements with respect to the securities it holds that paid the dividends distributed to the shareholder (or, in the case of certain preferred stocks, the holding requirement of 91 days during the 181-dayperiod beginning on the date that is 90 days before the date on which the stock becomes ex-dividendwith respect to such dividend); (ii) the Fund or the shareholder is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to substantially similar or related property; or (iii) the shareholder

108

elects to treat such dividend as investment income under Section 163(d)(4)(B) of the Internal Revenue Code. Dividends received by the Fund from a REIT or another RIC may be treated as qualified dividend income only to the extent the dividend distributions are attributable to qualified dividend income received by such REIT or other RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income. However, for tax years beginning after December 31, 2017 and before January 1, 2026, a non-corporatetaxpayer who is a direct REIT shareholder may claim a 20% "qualified business income" deduction for ordinary REIT dividends, and proposed regulations issued in January 2019, on which taxpayers may currently rely, permit a RIC to report dividends as eligible for this deduction to the extent the RIC's income is derived from ordinary REIT dividends (reduced by allocable RIC expenses). A shareholder may treat the dividends as such provided the RIC and the shareholder satisfy applicable holding period requirements, provided such shareholders satisfy the applicable holding period requirement. Distributions by the Fund of its net short-term capital gains will be taxable as ordinary income.

Market Discount. Any market discount recognized on a bond is taxable as ordinary income. A market discount bond is a bond acquired in the secondary market at a price below redemption value or adjusted issue price if issued with original issue discount ("OID"). To the extent the Fund does not include the market discount in income as it accrues, gain on the Fund's disposition of such an obligation will be treated as ordinary income rather than capital gain to the extent of the accrued market discount.

Non-U.S.Investments. Income (including, in some cases, capital gains) received by the Fund from investments in non-U.S.securities may be subject to withholding and other taxes imposed by non-U.S.countries. Tax conventions between certain countries and the U.S. may reduce or eliminate such taxes in some cases. If more than 50% of the Fund's total assets at the close of its taxable year consists of securities of non-U.S.corporations, the Fund may elect for U.S. income tax purposes to treat non-U.S.income taxes paid by it as paid by its shareholders. The Fund may qualify for and make this election in some, but not necessarily all, of its taxable years. If the Fund were to make an election, shareholders of the Fund would be required to take into account an amount equal to their pro rata portions of such non-U.S.taxes in computing their taxable income and then treat an amount equal to those non-U.S.taxes as a U.S. federal income tax deduction or as a foreign tax credit against their U.S. federal income taxes. Shortly after any year for which it makes such an election, the Fund will report to its shareholders the amount per share of such non-U.S.income tax that must be included in each shareholder's gross income and the amount which will be available for the deduction or credit. No deduction for non-U.S.taxes may be claimed by a shareholder who does not itemize deductions. Certain limitations will be imposed on the extent to which the credit (but not the deduction) for non-U.S.taxes may be claimed.

Under Section 988 of the Internal Revenue Code, gains or losses attributable to fluctuations in exchange rates between the time the Fund accrues income or receivables or expenses or other liabilities denominated in a non-U.S.currency and the time the Fund actually collects such income or pays such liabilities are generally treated as ordinary income or ordinary loss. In general, gains (and losses) realized on debt instruments will be treated as Section 988 gain (or loss) to the extent attributable to changes in exchange rates between the U.S. dollar and the currencies in which the instruments are denominated. Similarly, gain or losses on non-U.S.currency, non-U.S.currency forward contracts, certain non-U.S.currency options or futures contracts and the disposition of debt securities denominated in non-U.S.currency, to the extent attributable to fluctuations in exchange rates between the acquisition and disposition dates, are also treated as ordinary income or loss unless the Fund were to elect otherwise.

109

Original Issue Discount. OID on tax-exemptbonds is recognized over the term of the bond and is tax-exemptto the holder of the bond. Special U.S. federal income tax rules apply to inflation-indexed bonds. Generally, all stated interest on such bonds is taken into income by the Fund under its regular method of accounting for interest income. The amount of a positive inflation adjustment, which results in an increase in the inflation-adjusted principal amount of the bond, is treated as OID. The OID is included in the Fund's gross income ratably during the period ending with the maturity of the bond, under the general OID inclusion rules. The amount of the Fund's OID in a taxable year with respect to a bond will increase the Fund's taxable income for such year without a corresponding receipt of cash, until the bond matures. As a result, the Fund may need to use other sources of cash to satisfy its distributions for such year. The amount of negative inflation adjustment, which results in a decrease in the inflation-adjusted principal amount of the bond, reduces the amount of interest (including stated, interest, OID, and market discount, if any) otherwise includible in the Fund's income with respect to the bond for the taxable year.

Reporting. If a shareholder recognizes a loss with respect to the Fund's shares of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder must file with the IRS a disclosure statement on IRS Form 8886. Direct shareholders of portfolio securities are in many cases exempted from this reporting requirement, but under current guidance, shareholders of a RIC are not exempted. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer's treatment of the loss is proper. Shareholders should consult their tax advisors to determine the applicability of these regulations in light of their individual circumstances.

Other Taxes. Dividends, distributions and redemption proceeds may also be subject to additional state, local and non-U.S.taxes depending on each shareholder's particular situation.

Taxation of Non-U.S.Shareholders. Dividends paid by the Fund to non-U.S.shareholders are generally subject to withholding tax at a 30% rate or a reduced rate specified by an applicable income tax treaty to the extent derived from investment income and short-term capital gains. Dividends paid by the Fund from net tax-exemptincome or long-term capital gains are generally not subject to such withholding tax. In order to obtain a reduced rate of withholding, a non-U.S.shareholder will be required to provide an IRS Form W-8BENor IRS Form W-8BEN-Ecertifying its entitlement to benefits under a treaty. The withholding tax does not apply to regular dividends paid to a non-U.S.shareholder who provides an IRS Form W-8ECI,certifying that the dividends are effectively connected with the non-U.S.shareholder's conduct of a trade or business within the U.S. Instead, the effectively connected dividends will be subject to regular U.S. income tax as if the non-U.S.shareholder were a U.S. shareholder. A non-U.S.corporation receiving effectively connected dividends may also be subject to additional "branch profits tax" imposed at a rate of 30% (or lower treaty rate). A non-U.S.shareholder who fails to provide an IRS Form W-8BEN,IRS Form W-8BEN-Eor other applicable form may be subject to backup withholding at the appropriate rate.

Properly-reported dividends are generally exempt from U.S. federal withholding tax where they (i) are paid in respect of the Fund's "qualified net interest income" (generally, the Fund's U.S. source interest income, other than certain contingent interest and interest from obligations of a corporation or partnership in which the Fund is at least a 10% shareholder or partner, reduced by expenses that are allocable to such income); or (ii) are paid in respect of the Fund's "qualified short-term capital gains" (generally, the excess of the Fund's net short-term capital gain over the Fund's long-term capital loss for such taxable year). However, depending on its circumstances, the Fund may report all, some or none of its potentially eligible dividends as such qualified net interest income or as qualified short-term capital gains and/or treat such dividends, in whole or in part, as ineligible for this exemption from withholding. In order to qualify for this exemption from withholding, a non-U.S.shareholder will need to comply with applicable certification requirements relating to its non-U.S.status (including, in general,

110

furnishing an IRS Form W-8BEN,IRS Form W-8BEN-Eor substitute Form). In the case of shares held through an intermediary, the intermediary may withhold even if the Fund reports the payment as qualified net interest income or qualified short-term capital gain. Non-U.S.shareholders should contact their intermediaries with respect to the application of these rules to their accounts.

Special rules may apply to a foreign shareholder receiving the Fund distribution if at least 50% of the Fund's assets consist of interests in U.S. real property interests, including certain REITs and U.S. real property holding corporations (as defined in the Internal Revenue Code and Treasury regulations). Fund distributions that are attributable to gain from the disposition of a U.S. real property interest will be taxable as ordinary dividends and subject to withholding at a 30% or lower treaty rate if the foreign shareholder held no more than 5% of the Fund's shares at any time during the one-yearperiod ending on the date of the distribution. If the foreign shareholder held at least 5% of the Fund's shares, the distribution would be treated as income effectively connected with a trade or business within the U.S. and the foreign shareholder would be subject to withholding tax at a rate of 21% and would generally be required to file a U.S. federal income tax return.

Similar consequences would generally apply to a foreign shareholder's gain on the sale of Fund shares unless the Fund is domestically controlled (meaning that more than 50% of the value of the Fund's shares is held by U.S. shareholders) or the foreign shareholder owns no more than 5% of the Fund's shares at any time during the five-year period ending on the date of sale. Finally, a domestically controlled Fund may be required to recognize a portion of its gain on the in-kinddistribution of certain U.S. real property interests. Shareholders that are nonresident aliens or foreign entities are urged to consult their own tax advisors concerning the particular tax consequences to them of an investment in the Fund.

The rules laid out in the previous paragraph, other than the withholding rules, will apply notwithstanding the Fund's participation in a wash sale transaction or its payment of a substitute dividend.

Shareholders that are nonresident aliens or foreign entities are urged to consult their own tax advisors concerning the particular tax consequences to them of an investment in the Fund.

Separately, a 30% withholding tax is currently imposed on U.S.-source dividends, interest and other income items paid to: (i) foreign financial institutions, including non-U.S.investment funds, unless they agree to collect and disclose to the IRS information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to: (i) enter into agreements with the IRS that state that they will provide the IRS information including the names, addresses and taxpayer identification numbers of direct and indirect U.S. account holders; comply with due diligence procedures with respect to the identification of U.S. accounts; report to the IRS certain information with respect to U.S. accounts maintained; agree to withhold tax on certain payments made to non-compliantforeign financial institutions or to account holders who fail to provide the required information; and determine certain other information as to their account holders, or (ii) in the event that an applicable intergovernmental agreement and implementing legislation are adopted, provide local revenue authorities with similar account holder information. Other foreign entities will need to provide the name, address and taxpayer identification number of each substantial U.S. owner or provide certifications of no substantial U.S. ownership, unless certain exceptions apply.

Shares of the Fund held by a non-U.S.shareholder at death will be considered situated within the U.S. and subject to the U.S. estate tax.

The foregoing discussion is a summary of certain material U.S. federal income tax considerations only and is not intended as a substitute for careful tax planning. Purchasers of shares should consult their

111

own tax advisors as to the tax consequences of investing in such shares, including consequences under state, local and non-U.S.tax laws. Finally, the foregoing discussion is based on applicable provisions of the Internal Revenue Code, regulations, judicial authority and administrative interpretations in effect on the date of this SAI. Changes in applicable authority could materially affect the conclusions discussed above, and such changes often occur.

Open-EndFund Proxy Voting Policy

Procedures Governing Delegation of Proxy Voting to Fund Advisers

Effective Date: August 1, 2021

Last Review Date: August 1, 2022

Open-EndMutual Funds (including money market funds)

iShares ETFs and BlackRock ETFs

Objective and Scope

Set forth below is the Open-EndFund Proxy Voting Policy.

Policy / Document Requirements and Statements

The Boards of Trustees/Directors ("Directors") of open-endfunds (the "Funds") advised by BlackRock Fund Advisors or BlackRock Advisors, LLC ("BlackRock"), have the responsibility for the oversight of voting proxies relating to portfolio securities of the Funds, and have determined that it is in the best interests of the Funds and their shareholders to delegate the responsibility to vote proxies to BlackRock, subject to the principles outlined in this Policy, as part of BlackRock's authority to manage, acquire and dispose of account assets, all as contemplated by the Funds' respective investment management agreements.

BlackRock has adopted guidelines and procedures (together and as from time to time amended, the "BlackRock Proxy Voting Guidelines") governing proxy voting by accounts managed by BlackRock.

BlackRock will cast votes on behalf of each of the Funds on specific proxy issues in respect of securities held by each such Fund (or may refrain from voting) in accordance with the BlackRock Proxy Voting Guidelines.

BlackRock will report on an annual basis to the Directors on (1) a summary of all proxy votes that BlackRock has made on behalf of the Funds in the preceding year together with a representation that all votes were in accordance with the BlackRock Proxy Voting Guidelines, and (2) any changes to the BlackRock Proxy Voting Guidelines that have not previously been reported.

BlackRock Investment Stewardship

Global Principles

Effective as of January 2023

A-2

Contents

The purpose of this document is to provide an overarching explanation of BlackRock's approach globally to our responsibilities as a shareholder on behalf of our clients, our expectations of companies, and our commitments to clients in terms of our own governance and transparency.

A-3

Introduction to BlackRock

BlackRock's purpose is to help more and more people experience financial well-being. We manage assets on behalf of institutional and individual clients, across a full spectrum of investment strategies, asset classes, and regions. Our client base includes pension plans, endowments, foundations, charities, official institutions, insurers, and other financial institutions, as well as individuals around the world. As part of our fiduciary duty to our clients, we consider it one of our responsibilities to promote sound corporate governance, as an informed, engaged shareholder on their behalf. At BlackRock, this is the responsibility of the Investment Stewardship team.

Philosophy on investment stewardship

Companies are responsible for ensuring they have appropriate governance structures to serve the interests of shareholders and other key stakeholders. We believe that there are certain fundamental rights attached to shareholding. Companies and their boards should be accountable to shareholders and structured with appropriate checks and balances to ensure that they operate in shareholders' best interests to create sustainable value. Shareholders should have the right to vote to elect, remove, and nominate directors, approve the appointment of the auditor, and amend the corporate charter or by-laws.Shareholders should be able to vote on key board decisions that are material to the protection of their investment, including but not limited to, changes to the purpose of the business, dilution levels and pre-emptiverights, and the distribution of income and capital structure. In order to make informed decisions, shareholders need sufficient and timely information. In addition, shareholder voting rights should be proportionate to their economic ownership-the principle of "one share, one vote" helps achieve this balance.

Consistent with these shareholder rights, BlackRock has a responsibility to monitor and provide feedback to companies in our role as stewards of our clients' investments. Investment stewardship is how we use our voice as an investor to promote sound corporate governance and business practices to help maximize long-term shareholder value for our clients, the vast majority of whom are investing for long-term goals such as retirement. BlackRock Investment Stewardship (BIS) does this through engagement with management teams and/or board members on material business issues and, for those clients who have given us authority, through voting proxies in their best long-term financial interests.¹ We also contribute to consultations on public policy and private sector initiatives on industry standards, consistent with our clients' interests as long-term shareholders.

BlackRock looks to companies to provide timely, accurate, and comprehensive disclosure on all material governance and business matters. This transparency allows shareholders to appropriately understand and assess how relevant risks and opportunities are being effectively identified and managed. Where company reporting and disclosure is inadequate or where the governance approach taken may be inconsistent with durable, long-term value creation for shareholders, we will engage with a company and/or vote in a manner that advances long-term shareholders' interests.

BlackRock views engagement as an important activity; engagement provides us with the opportunity to improve our understanding of the business and of the risks and opportunities that are material to the

A-4

companies in which our clients invest. Engagement may also inform our voting decisions. As long-term investors on behalf of clients, we seek to have regular and continuing dialogue with executives and board directors to advance sound governance and durable business practices aligned with long-term value creation, as well as to understand the effectiveness of the company's management and oversight of material issues. Engagement is an important mechanism for providing feedback on company practices and disclosures, particularly where we believe they could be enhanced to support a company's ability to deliver financial performance. Similarly, it provides us with an opportunity to hear directly from company boards and management on how they believe their actions are aligned with durable, long-term value creation.

We generally vote in support of management and boards that exhibit an approach to decision-making that is consistent with creating durable, long-term value for shareholders. If we have concerns about a company's approach, we may choose to explain our expectations to the company's board and management. Following that engagement, we may signal through our voting that we have outstanding concerns, generally by voting against the re-electionof directors we view as having responsibility for an issue. We apply our regional proxy voting guidelines to achieve the outcome that is most aligned with our clients' long-term financial interests.

Key themes

We recognize that accepted standards and norms of corporate governance can differ between markets. However, in our experience, there are certain fundamental elements of governance practice that are intrinsic globally to a company's ability to create long-term value for shareholders. These global themes are set out in this overarching set of principles (the Principles), which are anchored in transparency and accountability. At a minimum, it is our view that companies should observe the accepted corporate governance standards in their domestic market and ask that, if they do not, they explain how their approach better supports durable, long-term value creation.

These Principles cover seven key themes:

Our regional and market-specific voting guidelines explain how these Principles inform our voting decisions in relation to specific ballot items for shareholder meetings.

Boards and directors

Our primary focus is on the performance of the board of directors to promote sound corporate governance. The performance of the board is critical to the economic success of the company and the protection of shareholders' interests. As part of their responsibilities, board members owe fiduciary duties to shareholders in overseeing the strategic direction and operation of the company. For this reason, BIS sees engaging with and the election of directors as one of our most important and impactful responsibilities.

A-5

We support boards whose approach is consistent with creating durable, long-term value. This includes the effective corporate governance and management of material sustainability-related risks and opportunities,² as well as the consideration of the company's key constituents including their employees, clients, suppliers, and the communities within which they operate. The board should establish and maintain a framework of robust and effective governance mechanisms to support its oversight of the company's strategic aims. We look to the board to articulate the effectiveness of these mechanisms in overseeing the management of business risks and opportunities and the fulfillment of the company's purpose. Disclosure of all material issues that affect the company's long-term strategy and ability to create value is essential for shareholders to be able to appropriately understand and assess how risks are effectively identified, managed and mitigated.

Where a company has not adequately disclosed and demonstrated that they have fulfilled these responsibilities, we will consider voting against the re-electionof directors whom we consider to have particular responsibility for the issue. We assess director performance on a case-by-casebasis and in light of each company's circumstances, taking into consideration our assessment of their governance, business practices that support durable, long-term value creation, and performance. In serving the interests of shareholders, the responsibility of the board of directors includes, but is not limited to, the following:

A-6

There should be clear descriptions of the role of the board and the committees of the board and how they engage with and oversee management. Set out below are ways in which boards and directors can demonstrate a commitment to acting in the best long-term economic interests of all shareholders.

We will seek to engage with the appropriate directors where we have concerns about the performance of the company, board, or individual directors and may signal outstanding concerns in our voting. While we consider these principles to be globally relevant, when assessing a board's composition and governance processes, we consider local market norms and regulations.

Regular accountability

It is our view that directors should stand for re-electionon a regular basis, ideally annually. In our experience, annual re-electionsallow shareholders to reaffirm their support for board members or hold them accountable for their decisions in a timely manner. When board members are not re-electedannually, in our experience, it is good practice for boards to have a rotation policy to ensure that, through a board cycle, all directors have had their appointment re-confirmed,with a proportion of directors being put forward for re-electionat each annual general meeting.

Effective board composition

Regular director elections also give boards the opportunity to adjust their composition in an orderly way to reflect the evolution of the company's strategy and the market environment. In our view, it is beneficial for new directors to be brought onto the board periodically to refresh the group's thinking and in a manner that supports both continuity and appropriate succession planning. We consider the average overall tenure of the board, where we are seeking a balance between the knowledge and experience of longer-serving members and the fresh perspectives of newer members. We encourage companies to keep under regular review the effectiveness of their board (including its size), and assess directors nominated for election or re-electionin the context of the composition of the board as a whole. This assessment should consider a number of factors, including the potential need to address gaps in skills, experience, independence, and diversity.

In our view, there should be a sufficient number of independent directors, free from conflicts of interest or undue influence from connected parties, to ensure objectivity in the decision-making of the board and its ability to oversee management. Common impediments to independence may include but are not limited to:

In our experience, boards are most effective at overseeing and advising management when there is a senior independent board leader. This director may chair the board, or, where the chair is also the CEO (or is otherwise not independent), be designated as a lead independent director. The role of this director is to enhance the effectiveness of the independent members of the board through shaping the agenda, ensuring adequate information is provided to the board, and encouraging independent director participation in board deliberations. The lead independent director or another appropriate director should be available to shareholders in those situations where an independent director is best placed to explain and contextualize a company's approach.

A-7

When nominating new directors to the board, we look to companies to provide sufficient information on the individual candidates so that shareholders can assess the suitability of each individual nominee and the overall board composition. These disclosures should give an understanding of how the collective experience and expertise of the board aligns with the company's long-term strategy and business model. Highly qualified, engaged directors with professional characteristics relevant to a company's business enhance the ability of the board to add value and be the voice of shareholders in board discussions. In our view, a strong board provides a competitive advantage to a company, providing valuable oversight and contributing to the most important management decisions that support long-term financial performance.

It is in this context that we are interested in diversity in the board room. We see it as a means to promoting diversity of thought and avoiding "group think" in the board's exercise of its responsibilities to advise and oversee management. It allows boards to have deeper discussions and make more resilient decisions. We ask boards to disclose how diversity is considered in board composition, including professional characteristics, such as a director's industry experience, specialist areas of expertise and geographic location; as well as demographic characteristics such as gender, race/ethnicity and age.

We look to understand a board's diversity in the context of a company's domicile, market capitalization, business model and strategy. Increasingly, we see leading boards adding members whose experience deepens the board's understanding of the company's customers, employees and communities. Self-identified board demographic diversity can usefully be disclosed in aggregate, consistent with local law. We believe boards should aspire to meaningful diversity of membership, at least consistent with local regulatory requirements and best practices, while recognizing that building a strong, diverse board can take time.

This position is based on our view that diversity of perspective and thought - in the board room, in the management team and throughout the company - leads to better long term economic outcomes for companies. Academic research already reveals correlations between specific dimensions of diversity and effects on decision-making processes and outcomes.⁴ In our experience, greater diversity in the board room contributes to more robust discussions and more innovative and resilient decisions. Over time, greater diversity in the board room can also promote greater diversity and resilience in the leadership team, and the workforce more broadly. That diversity can enable companies to develop businesses that more closely reflect and resonate with the customers and communities they serve.

There are matters for which the board has responsibility that may involve a conflict of interest for executives or for affiliated directors. It is our view that objective oversight of such matters is best achieved when the board forms committees comprised entirely of independent directors. In many markets, these committees of the board specialize in audit, director nominations, and compensation matters. An ad hoc committee might also be formed to decide on a special transaction, particularly one involving a related party, or to investigate a significant adverse event.

Sufficient capacity

As the role and expectations of a director are increasingly demanding, directors must be able to commit an appropriate amount of time to board and committee matters. It is important that directors

A-8

have the capacity to meet all of their responsibilities - including when there are unforeseen events - and therefore, they should not take on an excessive number of roles that would impair their ability to fulfill their duties.

Auditors and audit-related issues

BlackRock recognizes the critical importance of financial statements, which should provide a true and fair picture of a company's financial condition. Accordingly, the assumptions made by management and reviewed by the auditor in preparing the financial statements should be reasonable and justified.

The accuracy of financial statements, inclusive of financial and non-financialinformation as required or permitted under market-specific accounting rules, is of paramount importance to BlackRock. Investors increasingly recognize that a broader range of risks and opportunities have the potential to materially impact financial performance. Over time, we anticipate investors and other users of company reporting will increasingly seek to understand and scrutinize the assumptions underlying financial statements, particularly those that pertain to the impact of the transition to a low carbon economy on a company's business model and asset mix. We recognize that this is an area of evolving practice and we look to international standards setters, the International Accounting Standards Board (IASB) and the International Auditing and Assurance Standards Board (IAASB) to provide additional guidance to companies.

In this context, audit committees, or equivalent, play a vital role in a company's financial reporting system by providing independent oversight of the accounts, material financial and, where appropriate to the jurisdiction, non-financialinformation, internal control frameworks, and in the absence of a dedicated risk committee, Enterprise Risk Management systems. In our view, effective audit committee oversight strengthens the quality and reliability of a company's financial statements and provides an important level of reassurance to shareholders.

We hold members of the audit committee or equivalent responsible for overseeing the management of the audit function. Audit committees or equivalent should have clearly articulated charters that set out their responsibilities and have a rotation plan in place that allows for a periodic refreshment of the committee membership to introduce fresh perspectives to audit oversight. We recognize that audit committees will rely on management, internal audit and the independent auditor in fulfilling their responsibilities but look to committee members to demonstrate they have relevant expertise to monitor and oversee those functions.

We take particular note of unexplained changes in reporting methodology, cases involving significant financial restatements, or ad hoc notifications of material financial weakness. In this respect, audit committees should provide timely disclosure on the remediation of Key and Critical Audit Matters identified either by the external auditor or internal audit function.

The integrity of financial statements depends on the auditor being free of any impediments to being an effective check on management. To that end, it is important that auditors are, and are seen to be, independent. Where an audit firm provides services to the company in addition to the audit, the fees earned should be disclosed and explained. Audit committees should have in place a procedure for assessing annually the independence of the auditor and the quality of the external audit process.

Comprehensive disclosure provides investors with a sense of the company's long-term operational risk management practices and, more broadly, the quality of the board's oversight. The audit committee or equivalent, or a dedicated risk committee, should periodically review the company's risk assessment and risk management policies and the significant risks and exposures identified by management, the

A-9

internal auditors or the independent accountants, and management's steps to address them. In the absence of robust disclosures, we may reasonably conclude that companies are not adequately managing risk.

Capital structure, mergers, asset sales, and other special transactions

The capital structure of a company is critical to shareholders as it impacts the value of their investment and the priority of their interest in the company relative to that of other equity or debt investors. Pre-emptiverights are a key protection for shareholders against the dilution of their interests.

Effective voting rights are basic rights of share ownership. It is our view that one vote for one share as a guiding principle supports effective corporate governance. Shareholders, as the residual claimants, have the strongest interest in protecting company value, and voting rights should match economic exposure.

In principle, we disagree with the creation of a share class with equivalent economic exposure and preferential, differentiated voting rights. In our view, this structure violates the fundamental corporate governance principle of proportionality and results in a concentration of power in the hands of a few shareholders, thus disenfranchising other shareholders and amplifying any potential conflicts of interest. However, we recognize that in certain markets, at least for a period of time, companies may have a valid argument for listing dual classes of shares with differentiated voting rights. In our view, such companies should review these share class structures on a regular basis or as company circumstances change.

Additionally, they should seek shareholder approval of their capital structure on a periodic basis via a management proposal at the company's shareholder meeting. The proposal should give unaffiliated shareholders the opportunity to affirm the current structure or establish mechanisms to end or phase out controlling structures at the appropriate time, while minimizing costs to shareholders.

In assessing mergers, asset sales, or other special transactions, BlackRock's primary consideration is the long-term economic interests of our clients as shareholders. Boards proposing a transaction need to clearly explain the economic and strategic rationale behind it. We will review a proposed transaction to determine the degree to which it can enhance long-term shareholder value. We would prefer that proposed transactions have the unanimous support of the board and have been negotiated at arm's length. We may seek reassurance from the board that executives' and/or board members' financial interests in a given transaction have not adversely affected their ability to place shareholders' interests before their own. Where the transaction involves related parties, the recommendation to support should come from the independent directors, a best practice in most markets, and ideally, the terms should have been assessed through an independent appraisal process. In addition, it is good practice that it be approved by a separate vote of the non-conflictedparties.

As a matter of sound governance practice, shareholders should have a right to dispose of company shares in the open market without unnecessary restriction. In our view, corporate mechanisms designed to limit shareholders' ability to sell their shares are contrary to basic property rights. Such mechanisms can serve to protect and entrench interests other than those of the shareholders. In our experience, shareholders are broadly capable of making decisions in their own best interests. We encourage any so-called"shareholder rights plans" proposed by a board to be subject to shareholder approval upon introduction and periodically thereafter.

Compensation and benefits

In most markets, one of the most important roles for a company's board of directors is to put in place a compensation structure that incentivizes and rewards executives appropriately. There should be a clear link between variable pay and operational and financial performance. Performance metrics should be stretching and aligned with a company's strategy and business model. BIS does not have a position on the use of sustainability-related criteria, but in our view, where companies choose to include them, they should be as rigorous as other financial or operational targets. Long-term incentive plans should vest over timeframes aligned with the delivery of long-term shareholder value. Compensation committees should guard against contractual arrangements that would entitle executives to material compensation for early termination of their employment. Finally, pension contributions and other deferred compensation arrangements should be reasonable in light of market practice.

We are not supportive of one-offor special bonuses unrelated to company or individual performance. Where discretion has been used by the compensation committee or its equivalent, we expect disclosure relating to how and why the discretion was used, and how the adjusted outcome is aligned with the interests of shareholders. We acknowledge that the use of peer group evaluation by compensation committees can help ensure competitive pay; however, we are concerned when the rationale for increases in total compensation at a company is solely based on peer benchmarking rather than a rigorous measure of outperformance. We encourage companies to clearly explain how compensation outcomes have rewarded outperformance against peer firms.

We believe consideration should be given to building claw back provisions into incentive plans such that executives would be required to forgo rewards when they are not justified by actual performance and/or when compensation was based on faulty financial reporting or deceptive business practices. We also favor recoupment from any senior executive whose behavior caused material financial harm to shareholders, material reputational risk to the company, or resulted in a criminal investigation, even if such actions did not ultimately result in a material restatement of past results.

Non-executivedirectors should be compensated in a manner that is commensurate with the time and effort expended in fulfilling their professional responsibilities. Additionally, these compensation arrangements should not risk compromising directors' independence or aligning their interests too closely with those of the management, whom they are charged with overseeing.

We use third party research, in addition to our own analysis, to evaluate existing and proposed compensation structures. We may vote against members of the compensation committee or equivalent board members for poor compensation practices or structures.

Material sustainability-related risks and opportunities

It is our view that well-managed companies will effectively evaluate and manage material sustainability-related risks and opportunities relevant to their businesses. Appropriate oversight of sustainability considerations is a core component of having an effective governance framework, which supports durable, long-term value creation.

Robust disclosure is essential for investors to effectively evaluate companies' strategy and business practices related to material sustainability-related risks and opportunities. Given the increased understanding of material sustainability-related risks and opportunities and the need for better information to assess them, BlackRock advocates for continued improvement in companies' reporting, where necessary, and will express any concerns through our voting where a company's actions or disclosures are inadequate.

A-11

BlackRock encourages companies to use the framework developed by the Task Force on Climate-related Financial Disclosures (TCFD) to disclose their approach to ensuring they have a sustainable business model and to supplement that disclosure with industry-specific metrics such as those identified by the Sustainability Accounting Standards Board (SASB), now part of the International Sustainability Standards Board (ISSB) under the International Financial Reporting Standards (IFRS) Foundation.⁵ While the TCFD framework was developed to support climate-related risk disclosure, the four pillars of the TCFD governance, strategy, risk management, and metrics and targets are a useful way for companies to disclose how they identify, assess, manage, and oversee a variety of sustainability-related risks and opportunities. SASB's industry-specific guidance (as identified in its materiality map) is beneficial in helping companies identify key performance indicators (KPIs) across various dimensions of sustainability that are considered to be financially material and decision-useful within their industry. In particular, we encourage companies to consider reporting on nature-related factors, given the growing materiality of these issues for many businesses.⁶ We recognize that some companies may report using different standards, which may be required by regulation, or one of a number of voluntary standards. In such cases, we ask that companies highlight the metrics that are industry- or company-specific.

Climate and other sustainability-related disclosures often require companies to collect and aggregate data from various internal and external sources. We recognize that the practical realities of data-collection and reporting may not line up with financial reporting cycles and companies may require additional time after their fiscal year-endto accurately collect, analyze and report this data to investors. To give investors time to assess the data, we encourage companies to produce climate and other sustainability-related disclosures sufficiently in advance of their annual meeting.

Companies may also adopt or refer to guidance on sustainable and responsible business conduct issued by supranational organizations such as the United Nations or the Organization for Economic Cooperation and Development. Further, industry initiatives on managing specific operational risks may provide useful guidance to companies on best practices and disclosures. Companies should disclose any relevant global climate and other sustainability-related standards adopted, the industry initiatives in which they participate, any peer group benchmarking undertaken, and any assurance processes to help investors understand their approach to sustainable and responsible business practices.

Climate risk

It is our view that climate change has become a key factor in many companies' long-term prospects. As such, as long-term investors we are interested in understanding how companies may be impacted by material climate-related risks and opportunities - just as we seek to understand other business-relevant risks and opportunities - and how these factors are considered within strategy in a manner consistent with the company's business model and sector. Specifically, we look for companies to disclose strategies they have in place that mitigate and are resilient to any material risks to their long-term business model associated with a range of climate-related scenarios, including a scenario in

A-12

which global warming is limited to well below 2°C, considering global ambitions to achieve a limit of 1.5°C.⁷ It is, of course, up to each company to define their own strategy: that is not the role of BlackRock or other investors.

BIS recognizes that climate change can be challenging for many companies, as they seek to drive long-term value by mitigating risks and capturing opportunities. A growing number of companies, financial institutions, as well as governments, have committed to advancing decarbonization in line with the Paris Agreement. There is growing consensus that companies can benefit from the more favorable macro-economic environment under an orderly, timely and equitable global energy transition.⁸ Yet the path ahead is deeply uncertain and uneven, with different parts of the economy moving at different speeds.⁹ Many companies are asking what their role should be in contributing to an orderly and equitable transition - in ensuring a reliable energy supply and energy security, and in protecting the most vulnerable from energy price shocks and economic dislocation. In this context, we encourage companies to include in their disclosure a business plan for how they intend to deliver long-term financial performance through a transition to global net zero carbon emissions, consistent with their business model and sector.

We look to companies to disclose short-, medium- and long-term targets, ideally science-based targets where these are available for their sector, for Scope 1 and 2 greenhouse gas emissions (GHG) reductions and to demonstrate how their targets are consistent with the long-term economic interests of their shareholders. Many companies have an opportunity to use and contribute to the development of low carbon energy sources and technologies that will be essential to decarbonizing the global economy over time. We also recognize that continued investment in traditional energy sources, including oil and gas, is required to maintain an orderly and equitable transition - and that divestiture of carbon-intensive assets is unlikely to contribute to global emissions reductions. We encourage companies to disclose how their capital allocation to various energy sources is consistent with their strategy.

At this stage, we view Scope 3 emissions differently from Scopes 1 and 2, given methodological complexity, regulatory uncertainty, concerns about double-counting, and lack of direct control by companies. While we welcome any disclosures and commitments companies choose to make regarding Scope 3 emissions, we recognize these are provided on a good-faith basis as methodology develops. Our publicly available commentaryprovides more information on our approach to climate risk.

Key stakeholder interests

In order to advance long-term shareholders' interests, companies should consider the interests of the various parties on whom they depend for their success over time. It is for each company to determine their key stakeholders based on what is material to their business and long-term financial performance. Most commonly, key stakeholders include employees, business partners (such as suppliers and distributors), clients and consumers, regulators, and the communities in which they operate.

A-13

Considering the interests of key stakeholders recognizes the collective nature of long-term value creation and the extent to which each company's prospects for growth are tied to its ability to foster strong sustainable relationships with and support from those stakeholders. Companies should articulate how they address adverse impacts that could arise from their business practices and affect critical business relationships with their stakeholders. We encourage companies to implement, to the extent appropriate, monitoring processes (often referred to as due diligence) to identify and mitigate potential adverse impacts and grievance mechanisms to remediate any actual adverse material impacts. In our view, maintaining trust within these relationships can contribute to a company's long-term success.

As a long-term shareholder on behalf of our clients, we find it helpful when companies disclose how they have identified their key stakeholders and considered their interests in business decision-making. We are also interested to understand the role of the board, which is well positioned to ensure that the approach taken is informed by and aligns with the company's strategy and purpose.

Other corporate governance matters and shareholder protections

It is our view that shareholders have a right to material and timely information on the financial performance and viability of the companies in which they invest. In addition, companies should publish information on the governance structures in place and the rights of shareholders to influence these structures. The reporting and disclosure provided by companies help shareholders assess whether their economic interests have been protected and the quality of the board's oversight of management. We believe shareholders should have the right to vote on key corporate governance matters, including changes to governance mechanisms, to submit proposals to the shareholders' meeting, and to call special meetings of shareholders.

Corporate Form

In our view, it is the responsibility of the board to determine the corporate form that is most appropriate given the company's purpose and business model.¹⁰ Companies proposing to change their corporate form to a public benefit corporation or similar entity should put it to a shareholder vote if not already required to do so under applicable law. Supporting documentation from companies or shareholder proponents proposing to alter the corporate form should clearly articulate how the interests of shareholders and different stakeholders would be impacted as well as the accountability and voting mechanisms that would be available to shareholders. As a fiduciary on behalf of clients, we generally support management proposals if our analysis indicates that shareholders' interests are adequately protected. Relevant shareholder proposals are evaluated on a case-by-casebasis.

Shareholder proposals

In most markets in which BlackRock invests on behalf of clients, shareholders have the right to submit proposals to be voted on by shareholders at a company's annual or extraordinary meeting, as long as eligibility and procedural requirements are met. The matters that we see put forward by shareholders address a wide range of topics, including governance reforms, capital management, and improvements in the management or disclosure of sustainability-related risks.

BlackRock is subject to certain requirements under antitrust law in the United States that place restrictions and limitations on how BlackRock can interact with the companies in which we invest on behalf of our clients, including our ability to submit shareholder proposals. As noted above, we can vote, on behalf of clients who authorize us to do so, on proposals put forth by others.

A-14

When assessing shareholder proposals, we evaluate each proposal on its merit, with a singular focus on its implications for long-term value creation. We consider the business and economic relevance of the issue raised, as well as its materiality and the urgency with which we believe it should be addressed. We take into consideration the legal effect of the proposal, as shareholder proposals may be advisory or legally binding depending on the jurisdiction. We would not support proposals that we believe would result in over-reaching into the basic business decisions of the company.

Where a proposal is focused on a material governance or sustainability-related risk that we agree needs to be addressed and the intended outcome is consistent with long-term value creation, we will look to the board and management to demonstrate that the company has met the intent of the request made in the shareholder proposal. Where our analysis and/or engagement indicate an opportunity for improvement in the company's approach to the issue, we may support shareholder proposals that are reasonable and not unduly prescriptive or constraining on management. Alternatively, or in addition, we may vote against the re-electionof one or more directors if, in our assessment, the board has not responded sufficiently or with an appropriate sense of urgency. While we may not agree with all aspects of a shareholder proponent's views or all facets of the proponent's supporting statement, we may still support proposals that address material governance or sustainability-related risks where we believe it would be helpful for shareholders to have more detailed information on how those risks are identified, monitored, and managed to support a company's ability to deliver long-term financial returns. We may also support a proposal if management is on track, but we believe that voting in favor might accelerate progress.

BlackRock's oversight of its investment stewardship activities

Oversight

BlackRock maintains three regional advisory committees (Stewardship Advisory Committees) for a) the Americas; b) Europe, the Middle East and Africa (EMEA); and c) Asia-Pacific, generally consisting of senior BlackRock investment professionals and/or senior employees with practical boardroom experience. The regional Stewardship Advisory Committees review and advise on amendments to BIS proxy voting guidelines covering markets within each respective region (Guidelines). The advisory committees do not determine voting decisions, which are the responsibility of BIS.

In addition to the regional Stewardship Advisory Committees, the Investment Stewardship Global Oversight Committee (Global Committee) is a risk-focused committee, comprised of senior representatives from various BlackRock investment teams, a senior legal representative, the Global Head of Investment Stewardship (Global Head), and other senior executives with relevant experience and team oversight. The Global Oversight Committee does not determine voting decisions, which are the responsibility of BIS.

The Global Head has primary oversight of the activities of BIS, including voting in accordance with the Guidelines, which require the application of professional judgment and consideration of each company's unique circumstances. The Global Committee reviews and approves amendments to these Principles. The Global Committee also reviews and approves amendments to the regional Guidelines, as proposed by the regional Stewardship Advisory Committees.

In addition, the Global Committee receives and reviews periodic reports regarding the votes cast by BIS, as well as updates on material process issues, procedural changes, and other risk oversight considerations. The Global Committee reviews these reports in an oversight capacity as informed by the BIS corporate governance engagement program and the Guidelines.

A-15

BIS carries out engagement with companies, monitors and executes proxy votes, and conducts vote operations (including maintaining records of votes cast) in a manner consistent with the relevant Guidelines. BIS also conducts research on corporate governance issues and participates in industry discussions to contribute to and keep abreast of important developments in the corporate governance field. BIS may utilize third parties for certain of the foregoing activities and performs oversight of those third parties. BIS may raise complicated or particularly controversial matters for internal discussion with the relevant investment teams and governance specialists for discussion and guidance prior to making a voting decision.

Vote execution

BlackRock votes on proxy issues when our clients authorize us to do so. We offer certain clients who prefer their holdings to be voted consistent with specific values or views Voting Choice.¹¹ When BlackRock votes on behalf of our clients, we carefully consider proxies submitted to funds and other fiduciary account(s) (Fund or Funds) for which we have voting authority. BlackRock votes (or refrains from voting) proxies for each Fund for which we have voting authority based on our evaluation of the best long-term economic interests of our clients as shareholders, in the exercise of our independent business judgment, and without regard to the relationship of the issuer of the proxy (or any shareholder proponent or dissident shareholder) to the Fund, the Fund's affiliates (if any), BlackRock or BlackRock's affiliates, or BlackRock employees (see "Conflicts management policies and procedures", below).

When exercising voting rights, BlackRock will normally vote on specific proxy issues in accordance with the Guidelines for the relevant market. The Guidelines are reviewed annually and are amended consistent with changes in the local market practice, as developments in corporate governance occur, or as otherwise deemed advisable by the applicable Stewardship Advisory Committees. BIS analysts may, in the exercise of their professional judgment, conclude that the Guidelines do not cover the specific matter upon which a proxy vote is required or that an exception to the Guidelines would be in the best long-term economic interests of BlackRock's clients.

In the uncommon circumstance of there being a vote with respect to fixed income securities or the securities of privately held issuers, the decision generally will be made by the Fund's portfolio managers and/or BIS based on their assessment of the particular transactions or other matters at issue.

In certain markets, proxy voting involves logistical issues which can affect BlackRock's ability to vote such proxies, as well as the desirability of voting such proxies. These issues include, but are not limited to: i) untimely notice of shareholder meetings; ii) restrictions on a foreigner's ability to exercise votes; iii) requirements to vote proxies in person; iv) "share-blocking" (requirements that investors who exercise their voting rights surrender the right to dispose of their holdings for some specified period in proximity to the shareholder meeting); v) potential difficulties in translating the proxy; vi) regulatory constraints; and vii) requirements to provide local agents with unrestricted powers of attorney to facilitate voting instructions. We are not supportive of impediments to the exercise of voting rights such as share-blocking or overly burdensome administrative requirements.

As a consequence, BlackRock votes proxies in these situations on a "best-efforts" basis. In addition, BIS may determine that it is generally in the best interests of BlackRock's clients not to vote proxies (or not to vote our full allocation) if the costs (including but not limited to opportunity costs associated with share-blocking constraints) associated with exercising a vote are expected to outweigh the benefit the client would derive by voting on the proposal.

A-16

Portfolio managers have full discretion to vote the shares in the Funds they manage based on their analysis of the economic impact of a particular ballot item on their investors. Portfolio managers may, from time to time, reach differing views on how best to maximize economic value with respect to a particular investment. Therefore, portfolio managers may, and sometimes do, vote shares in the Funds under their management differently from BIS or from one another. However, because BlackRock's clients are mostly long-term investors with long-term economic goals, ballots are frequently cast in a uniform manner.

Conflicts management policies and procedures

BIS maintains policies and procedures that seek to prevent undue influence on BlackRock's proxy voting activity. Such influence might stem from any relationship between the investee company (or any shareholder proponent or dissident shareholder) and BlackRock, BlackRock's affiliates, the Fund or the Fund's affiliates, or BlackRock employees. The following are examples of sources of perceived or potential conflicts of interest:

BlackRock has taken certain steps to mitigate perceived or potential conflicts including, but not limited to, the following:

A-17

In selecting a voting service provider, we assess several characteristics, including but not limited to: independence, an ability to analyze proxy issues and make recommendations in the best economic interest of our clients in accordance with the Guidelines, reputation for reliability and integrity, and operational capacity to accurately deliver the assigned recommendations in a timely manner. We may engage more than one voting service provider, in part to mitigate potential or perceived conflicts of interest at a single voting service provider. The Global Committee appoints and reviews the performance of the voting service providers, generally on an annual basis.

Securities lending

When so authorized, BlackRock acts as a securities lending agent on behalf of Funds. Securities lending is a well-regulated practice that contributes to capital market efficiency. It also enables funds to generate additional returns for a fund, while allowing fund providers to keep fund expenses lower.

With regard to the relationship between securities lending and proxy voting, BlackRock's approach is informed by our fiduciary responsibility to act in our clients' best interests. In most cases, BlackRock anticipates that the potential long-term value to the Fund of voting shares would be less than the potential revenue the loan may provide the Fund. However, in certain instances, BlackRock may determine, in its independent business judgment as a fiduciary, that the value of voting outweighs the securities lending revenue loss to clients and would therefore recall shares to be voted in those instances.

The decision to recall securities on loan as part of BlackRock's securities lending program in order to vote is based on an evaluation of various factors that include, but are not limited to, assessing potential securities lending revenue alongside the potential long-term value to clients of voting those securities (based on the information available at the time of recall consideration).¹² BIS works with colleagues in the Securities Lending and Risk and Quantitative Analysis teams to evaluate the costs and benefits to clients of recalling shares on loan.

A-18

Periodically, BlackRock reviews our process for determining whether to recall securities on loan in order to vote and may modify it as necessary.

Voting guidelines

The issue-specific Guidelines published for each region/country in which we vote are intended to summarize BlackRock's general philosophy and approach to issues that may commonly arise in the proxy voting context in each market where we invest. The Guidelines are not intended to be exhaustive. BIS applies the Guidelines on a case-by-casebasis, in the context of the individual circumstances of each company and the specific issue under review. As such, the Guidelines do not indicate how BIS will vote in every instance. Rather, they reflect our view about corporate governance issues generally, and provide insight into how we typically approach issues that commonly arise on corporate ballots.

Reporting and vote transparency

We are committed to transparency in the stewardship work we do on behalf of clients. We inform clients about our engagement and voting policies and activities through direct communication and through disclosure on our website. Each year we publish an annual report that provides a global overview of our investment stewardship engagement and voting activities and a voting spotlight that summarizes our voting over a proxy year.¹³ Additionally, we make public our market-specific voting guidelines for the benefit of clients and companies with whom we engage. We also publish commentaries to share our perspective on market developments and emerging key themes.

At a more granular level, we publish quarterly our vote record for each company that held a shareholder meeting during the period, showing how we voted on each proposal and explaining any votes against management proposals or on shareholder proposals. For shareholder meetings where a vote might be high profile or of significant interest to clients, we may publish a vote bulletin after the meeting, disclosing and explaining our vote on key proposals. We also publish a quarterly list of all companies with which we engaged and the key topics addressed in the engagement meeting.

In this way, we help inform our clients about the work we do on their behalf in promoting the governance and business models that support durable, long-term value creation.

BlackRock Investment Stewardship

Proxy voting guidelines for U.S. securities

January 2023

A-20

Contents

A-21

These guidelines should be read in conjunction with the BlackRock Investment Stewardship Global Principles.

Introduction

As stewards of our clients' investments, BlackRock believes it has a responsibility to engage with management teams and/or board members on material business issues and, for those clients who have given us authority, to vote proxies in the best long-term economic interests of their assets.

The following issue-specific proxy voting guidelines (the "Guidelines") summarize BlackRock Investment Stewardship's ("BIS") philosophy and approach to engagement and voting, as well as our view of governance best practices and the roles and responsibilities of boards and directors for publicly listed U.S. companies. These Guidelines are not intended to limit the analysis of individual issues at specific companies or provide a guide to how BIS will engage and/or vote in every instance. They are to be applied with discretion, taking into consideration the range of issues and facts specific to the company, as well as individual ballot items at shareholder meetings.

Voting guidelines

These guidelines are divided into eight key themes, which group together the issues that frequently appear on the agenda of shareholder meetings:

Boards and directors

An effective and well-functioning board is critical to the economic success of the company and the protection of shareholders' interests, inducting the establishment of appropriate governance structures that facilitate oversight of management and the company's strategic initiatives. As part of their responsibilities, board members owe fiduciary duties to shareholders in overseeing the strategic direction, operations, and risk management of the company. For this reason, BIS sees engagement with and the election of directors as one of our most critical responsibilities.

Disclosure of material issues that affect the company's long-term strategy and value creation, including, when relevant, material sustainability-related factors, is essential for shareholders to appropriately understand and assess how effectively the board is identifying, managing, and mitigating risks.

A-22

Where a company has not adequately demonstrated, through actions and/or disclosures, how material issues are appropriately identified, managed, and overseen, we will consider voting against the re-electionof those directors responsible for the oversight of such issues, as indicated below.

Independence

It is our view that a majority of the directors on the board should be independent to ensure objectivity in the decision-making of the board and its ability to oversee management. In addition, all members of audit, compensation, and nominating/
governance committees should be independent. Our view of independence may vary from listing standards.

Common impediments to independence may include:

Oversight role of the board

The board should exercise appropriate oversight of management and the business activities of the company. Where we determine that a board has failed to do so in a way that may impede a company's long-term value, we may vote against the responsible committees and/or individual directors.

Common circumstances are illustrated below:

A-23

In addition, we recognize that board leadership roles may vary in responsibility and time requirements in different markets around the world. In particular, where a director maintains a Chair role of a publicly listed company in European markets, we may consider that responsibility as equal to two board commitments, consistent with our EMEA Proxy Voting Guidelines. We will take the total number of board commitments across our global policies into account for director elections.

Risk oversight

Companies should have an established process for identifying, monitoring, and managing business and material risks. Independent directors should have access to relevant management information and outside advice, as appropriate, to ensure they can properly oversee risk. We encourage companies to provide transparency around risk management, mitigation, and reporting to the board. We are particularly interested in understanding how risk oversight processes evolve in response to changes in corporate strategy and/or shifts in the business and related risk environment. Comprehensive disclosures provide investors with a sense of the company's long-term risk management practices and, more broadly, the quality of the board's oversight. In the absence of robust disclosures, we may reasonably conclude that companies are not adequately managing risk.

Board Structure

Classified board of directors/staggered terms

Directors should be re-electedannually; classification of the board generally limits shareholders' rights to regularly evaluate a board's performance and select directors. While we will typically support proposals requesting board de-classification,we may make exceptions, should the board articulate an appropriate strategic rationale for a classified board structure. This may include when a company needs consistency and stability during a time of transition, e.g., newly public companies or companies undergoing a strategic restructuring. A classified board structure may also be justified at non-operatingcompanies, e.g., closed-endfunds or business development companies ("BDC"),¹⁶ in certain circumstances. However, in these instances, boards should periodically review the rationale for a classified structure and consider when annual elections might be more appropriate.

Without a voting mechanism to immediately address concerns about a specific director, we may choose to vote against the directors up for election at the time (see "Shareholder rights" for additional detail).

A-24

Independent leadership

There are two commonly accepted structures for independent leadership to balance the CEO role in the boardroom: 1) an independent Chair; or 2) a Lead Independent director when the roles of Chair and CEO are combined, or when the Chair is otherwise not independent.

In the absence of a significant governance concern, we defer to boards to designate the most appropriate leadership structure to ensure adequate balance and independence.¹⁷ However, BIS may vote against the most senior non-executivemember of the board when appropriate independence is lacking in designated leadership roles.

In the event that the board chooses to have a combined Chair/CEO or a non-independentChair, we support the designation of a Lead Independent director, with the ability to: 1) provide formal input into board meeting agendas; 2) call meetings of the independent directors; and 3) preside at meetings of independent directors. These roles and responsibilities should be disclosed and easily accessible.

The following table illustrates examples¹⁸ of responsibilities under each board leadership model:

A-25

CEO and management succession planning

Companies should have a robust CEO and senior management succession plan in place at the board level that is reviewed and updated on a regular basis. Succession planning should cover scenarios over both the long-term, consistent with the strategic direction of the company and identified leadership needs over time, as well as the short-term, in the event of an unanticipated executive departure. We encourage the company to explain their executive succession planning process, including where accountability lies within the boardroom for this task, without prematurely divulging sensitive information commonly associated with this exercise.

During a CEO transition, companies may elect for the departing CEO to maintain a role in the boardroom. We ask for disclosures to understand the timeframe and responsibilities of this role. In such instances, we typically look for the board to have appropriate independent leadership structures in place. (See chart above.)

Director compensation and equity programs

Compensation for directors should generally be structured to attract and retain directors, while also aligning their interests with those of shareholders. In our view, director compensation packages that are based on the company's long-term value creation and include some form of long-term equity compensation are more likely to meet this goal.

Board composition and effectiveness

Director qualifications and skills

We encourage boards to periodically review director qualifications and skills to ensure relevant experience and diverse perspectives are represented in the boardroom. To this end, performance reviews and skills assessments should be conducted by the nominating/governance committee or the Lead Independent Director. This process may include internal board evaluations; however, boards may also find it useful to periodically conduct an assessment with a third party. We encourage boards to disclose their approach to evaluations, including objectives of the evaluation; if an external party conducts the evaluation; the frequency of the evaluations; and, whether that evaluation occurs on an individual director basis.

A-26

Board term limits and director tenure

Where boards find that age limits or term limits are the most efficient and objective mechanism for ensuring periodic board refreshment, we generally defer to the board's determination in setting such limits. BIS will also consider the average board tenure to evaluate processes for board renewal. We may oppose boards that appear to have an insufficient mix of short-, medium-, and long-tenured directors.

Board diversity

As noted above, highly qualified, engaged directors with professional characteristics relevant to a company's business enhance the ability of the board to add value and be the voice of shareholders in board discussions. In our view, a strong board provides a competitive advantage to a company, providing valuable oversight and contributing to the most important management decisions that support long-term financial performance.

It is in this context that we are interested in diversity in the boardroom. We see it as a means to promoting diversity of thought and avoiding 'group think' in the board's exercise of its responsibilities to advise and oversee management. It allows boards to have deeper discussions and make more resilient decisions. We ask boards to disclose how diversity is considered in board composition, including professional characteristics, such as a director's industry experience, specialist areas of expertise and geographic location; as well as demographic characteristics such as gender, race/ethnicity, and age.

We look to understand a board's diversity in the context of a company's domicile, market capitalization, business model, and strategy. Increasingly, we see leading boards adding members whose experience deepens the board's understanding of the company's customers, employees, and communities. Self-identified board demographic diversity can usefully be disclosed in aggregate, consistent with local law. We believe boards should aspire to meaningful diversity of membership, at least consistent with local regulatory requirements and best practices, while recognizing that building a strong, diverse board can take time.

This position is based on our view that diversity of perspective and thought-in the boardroom, in the management team and throughout the company-leads to better long-term economic outcomes for companies. Academic and other research reveals correlations between specific dimensions of diversity and effects on decision-making processes and outcomes.¹⁹ In our experience, greater diversity in the boardroom contributes to more robust discussions and more innovative and resilient decisions. Over time, greater diversity in the boardroom can also promote greater diversity and resilience in the leadership team, and the workforce more broadly. That diversity can enable companies to develop businesses that more closely reflect and resonate with the customers and communities they serve.

In the U.S., we believe that boards should aspire to at least 30% diversity of membership,²⁰ and we encourage large companies, such as those in the S&P 500, to lead in achieving this standard. In our

A-27

view, an informative indicator of diversity for such companies is having at least two women and a director who identifies as a member of an underrepresented group.²¹ We recognize that it may take time and that companies with smaller market capitalizations and in certain sectors may face more challenges in pursuing diversity. Among these smaller companies, we look for the presence of diversity and take into consideration the progress that companies are making.

In order to help investors understand overall diversity, we look to boards to disclose:

To the extent that, based on our assessment of corporate disclosures, a company has not adequately explained their approach to diversity in their board composition, we may vote against members of the nominating/governance committee. Our publicly available commentary provides more information on our approach to board diversity.

Board size

We typically defer to the board in setting the appropriate size and believe that directors are generally in the best position to assess the optimal board size to ensure effectiveness. However, we may vote against the appropriate committees and/or individual directors if, in our view, the board is ineffective in its oversight, either because it is too small to allow for the necessary range of skills and experience or too large to function efficiently.

Board responsiveness and shareholder rights

Where we determine that a board has not acted in the best interests of the company's shareholders, or takes action to unreasonably limit shareholder rights, we may vote against the appropriate committees and/or individual directors. Common circumstances are illustrated below:

A-28

Responsiveness to shareholders

A board should be engaged and responsive to the company's shareholders, including acknowledging voting outcomes for director elections, compensation, shareholder proposals, and other ballot items. Where we determine that a board has not substantially addressed shareholder concerns that we deem material to the business, we may vote against the responsible committees and/or individual directors. Common circumstances are illustrated below:

Majority vote requirements

Directors should generally be elected by a majority of the shares voted. We will normally support proposals seeking to introduce bylaws requiring a majority vote standard for director elections. Majority vote standards generally assist in ensuring that directors who are not broadly supported by shareholders are not elected to serve as their representatives. As a best practice, companies with either a majority vote standard or a plurality vote standard should adopt a resignation policy for directors who do not receive support from at least a majority of votes cast. Where the company already has a sufficiently robust majority voting process in place, we may not support a shareholder proposal seeking an alternative mechanism.

We note that majority voting may not be appropriate in all circumstances, for example, in the context of a contested election, or for majority-controlled companies or those with concentrated ownership structures.

Cumulative voting

As stated above, a majority vote standard is generally in the best long-term interests of shareholders, as it ensures director accountability through the requirement to be elected by more than half of the votes cast. As such, we will generally oppose proposals requesting the adoption of cumulative voting, which may disproportionately aggregate votes on certain issues or director candidates.

A-29

Auditors and audit-related issues

BIS recognizes the critical importance of financial statements to provide a complete and accurate portrayal of a company's financial condition. Consistent with our approach to voting on directors, we seek to hold the audit committee of the board responsible for overseeing the management of the independent auditor and the internal audit function at a company.

We may vote against the audit committee members where the board has failed to facilitate quality, independent auditing. We look to public disclosures for insight into the scope of the audit committee responsibilities, including an overview of audit committee processes, issues on the audit committee agenda, and key decisions taken by the audit committee. We take particular note of cases involving significant financial restatements or material weakness disclosures, and we look for timely disclosure and remediation of accounting irregularities.

The integrity of financial statements depends on the auditor effectively fulfilling its role. To that end, we favor an independent auditor. In addition, to the extent that an auditor fails to reasonably identify and address issues that eventually lead to a significant financial restatement, or the audit firm has violated standards of practice, we may also vote against ratification.

From time to time, shareholder proposals may be presented to promote auditor independence or the rotation of audit firms. We may support these proposals when they are consistent with our views as described above.

Capital structure proposals

Equal voting rights

In our view, shareholders should be entitled to voting rights in proportion to their economic interests. In addition, companies that have implemented dual or multiple class share structures should review these structures on a regular basis, or as company circumstances change. Companies with multiple share classes should receive shareholder approval of their capital structure on a periodic basis via a management proposal on the company's proxy. The proposal should give unaffiliated shareholders the opportunity to affirm the current structure or establish mechanisms to end or phase out controlling structures at the appropriate time, while minimizing costs to shareholders. Where companies are unwilling to voluntarily implement "one share, one vote" within a specified timeframe, or are unresponsive to shareholder feedback for change over time, we generally support shareholder proposals to recapitalize stock into a single voting class.

Blank check preferred stock

We frequently oppose proposals requesting authorization of a class of preferred stock with unspecified voting, conversion, dividend distribution, and other rights ("blank check" preferred stock) because they may serve as a transfer of authority from shareholders to the board and as a possible entrenchment device. We generally view the board's discretion to establish voting rights on a when-issued basis as a potential anti-takeover device, as it affords the board the ability to place a block of stock with an investor sympathetic to management, thereby foiling a takeover bid without a shareholder vote.

Nonetheless, we may support the proposal where the company:

A-30

Increase in authorized common shares

BIS will evaluate requests to increase authorized shares on a case-by-casebasis, in conjunction with industry-specific norms and potential dilution, as well as a company's history with respect to the use of its common shares.

Increase or issuance of preferred stock

We generally support proposals to increase or issue preferred stock in cases where the company specifies the voting, dividend, conversion, and other rights of such stock and where the terms of the preferred stock appear reasonable.

Stock splits

We generally support stock splits that are not likely to negatively affect the ability to trade shares or the economic value of a share. We generally support reverse stock splits that are designed to avoid delisting or to facilitate trading in the stock, where the reverse split will not have a negative impact on share value (e.g., one class is reduced while others remain at pre-splitlevels). In the event of a proposal for a reverse split that would not proportionately reduce the company's authorized stock, we apply the same analysis we would use for a proposal to increase authorized stock.

Mergers, acquisitions, transactions, and other special situations

Mergers, acquisitions, and transactions

In assessing mergers, acquisitions, or other transactions- including business combinations involving Special Purpose Acquisition Companies ("SPACs") - BIS' primary consideration is the long-term economic interests of our clients as shareholders. Boards should clearly explain the economic and strategic rationale for any proposed transactions or material changes to the business. We will review a proposed transaction to determine the degree to which it has the potential to enhance long-term shareholder value. While mergers, acquisitions, asset sales, business combinations, and other special transaction proposals vary widely in scope and substance, we closely examine certain salient features in our analyses, such as:

A-31

Contested director elections and special situations

Contested elections and other special situations²² are assessed on a case-by-casebasis. We evaluate a number of factors, which may include: the qualifications and past performance of the dissident and management candidates; the validity of the concerns identified by the dissident; the viability of both the dissident's and management's plans; the ownership stake and holding period of the dissident; the likelihood that the dissident's strategy will produce the desired change; and whether the dissident represents the best option for enhancing long-term shareholder value.

We will evaluate the actions that the company has taken to limit shareholders' ability to exercise the right to nominate dissident director candidates, including those actions taken absent the immediate threat of a contested situation. BIS may take voting action against directors(up to and including the full board) where those actions are viewed as egregiously infringing on shareholder rights.

We will consider a variety of possible voting outcomes in contested situations, including the ability to support a mix of management and dissident nominees.

Poison pill plans

Where a poison pill is put to a shareholder vote by management, our policy is to examine these plans individually. Although we have historically opposed most plans, we may support plans that include a reasonable "qualifying offer clause." Such clauses typically require shareholder ratification of the pill and stipulate a sunset provision whereby the pill expires unless it is renewed. These clauses also tend to specify that an all-cashbid for all shares that includes a fairness opinion and evidence of financing does not trigger the pill, but forces either a special meeting at which the offer is put to a shareholder vote or requires the board to seek the written consent of shareholders, where shareholders could rescind the pill at their discretion. We may also support a pill where it is the only effective method for protecting tax or other economic benefits that may be associated with limiting the ownership changes of individual shareholders. Lastly, we look for shareholder approval of poison pill plans within one year of adoption of implementation.

Reimbursement of expense for successful shareholder campaigns

We generally do not support shareholder proposals seeking the reimbursement of proxy contest expenses, even in situations where we support the shareholder campaign. Introducing the possibility of such reimbursement may incentivize disruptive and unnecessary shareholder campaigns.

Executive compensation

A company's board of directors should put in place a compensation structure that balances incentivizing, rewarding, and retaining executives appropriately across a wide range of business outcomes. This structure should be aligned with shareholder interests, particularly the generation of sustainable, long-term value.

A-32

The compensation committee should carefully consider the specific circumstances of the company and the key individuals the board is focused on incentivizing. We encourage companies to ensure that their compensation plans incorporate appropriate and rigorous performance metrics, consistent with corporate strategy and market practice. Performance-based compensation should include metrics that are relevant to the business and stated strategy and/or risk mitigation efforts. Goals, and the processes used to set these goals, should be clearly articulated and appropriately rigorous. We use third party research, in addition to our own analysis, to evaluate existing and proposed compensation structures. We hold members of the compensation committee, or equivalent board members, accountable for poor compensation practices and/or structures.

There should be a clear link between variable pay and company performance that drives sustained value creation for our clients as shareholders. Where compensation structures provide for a front-loaded²³ award, we look for appropriate structures (including vesting and/or holding periods) that motivate sustained performance for shareholders over a number of years. We generally do not favor programs focused on awards that require performance levels to be met and maintained for a relatively short time period for payouts to be earned, unless there are extended vesting and/or holding requirements.

Compensation structures should generally drive outcomes that align the pay of the executives with performance of the company and the value received by shareholders. When evaluating performance, we examine both executive teams' efforts, as well as outcomes realized by shareholders. Payouts to executives should reflect both the executive's contributions to the company's ongoing success, as well as exogenous factors that impacted shareholder value. Where discretion has been used by the compensation committee, we look for disclosures relating to how and why the discretion was used and how the adjusted outcome is aligned with the interests of shareholders. While we believe special awards²⁴ should be used sparingly, we acknowledge that there may be instances when such awards are appropriate. When evaluating these awards, we consider a variety of factors, including the magnitude and structure of the award, the scope of award recipients, the alignment of the grant with shareholder value, and the company's historical use of such awards, in addition to other company-specific circumstances.

We acknowledge that the use of peer group evaluation by compensation committees can help calibrate competitive pay; however, we are concerned when the rationale for increases in total compensation is solely based on peer benchmarking.

We support incentive plans that foster the sustainable achievement of results- both financial and non-financial- consistent with the company's strategic initiatives. Compensation committees should guard against contractual arrangements that would entitle executives to material compensation for early termination of their contract. Finally, pension contributions and other deferred compensation arrangements should be reasonable in light of market practices. Our publicly available commentary provides more information on our approach to executive compensation.

Where executive compensation appears excessive relative to the performance of the company and/or compensation paid by peers, or where an equity compensation plan is not aligned with shareholders' interests, we may vote against members of the compensation committee.

A-33

"Say on Pay" advisory resolutions

In cases where there is a "Say on Pay" vote, BIS will respond to the proposal as informed by our evaluation of compensation practices at that particular company and in a manner that appropriately addresses the specific question posed to shareholders. Where we conclude that a company has failed to align pay with performance, we will vote against the management compensation proposal and relevant compensation committee members.

Frequency of "Say on Pay" advisory resolutions

BIS will generally support annual advisory votes on executive compensation. It is our view that shareholders should have the opportunity to express feedback on annual incentive programs and changes to long-term compensation before multiple cycles are issued. Where a company has failed to implement a "Say on Pay" advisory vote within the frequency period that received the most support from shareholders or a "Say on Pay" resolution is omitted without explanation, BIS may vote against members of the compensation committee.

Clawback proposals

We generally favor prompt recoupment from any senior executive whose compensation was based on faulty financial reporting or deceptive business practices. We also favor prompt recoupment from any senior executive whose behavior caused material financial harm to shareholders, material reputational risk to the company, or resulted in a criminal proceeding, even if such actions did not ultimately result in a material restatement of past results. This includes, but is not limited to, settlement agreements arising from such behavior and paid for directly by the company. We typically support shareholder proposals on these matters unless the company already has a robust clawback policy that sufficiently addresses our concerns.

Employee stock purchase plans

Employee stock purchase plans("ESPP") are an important part of a company's overall human capital management strategy and can provide performance incentives to help align employees' interests with those of shareholders. The most common form of ESPP qualifies for favorable tax treatment under Section 423 of the Internal Revenue Code. We will typically support qualified ESPP proposals.

Equity compensation plans

BIS supports equity plans that align the economic interests of directors, managers, and other employees with those of shareholders. Boards should establish policies prohibiting the use of equity awards in a manner that could disrupt the intended alignment with shareholder interests, such as the excessive pledging or heading of stock. We may support shareholder proposals requesting the establishment of such policies.

Our evaluation of equity compensation plans is based on a company's executive pay and performance relative to peers and whether the plan plays a significant role in a pay-for-performancedisconnect. We generally oppose plans that contain "evergreen" provisions, which allow for automatic annual increases of shares available for grant without requiring further shareholder approval; we note that the aggregate impacts of such increases are difficult to predict and may lead to significant dilution. We also generally oppose plans that allow for repricing without shareholder approval. We may oppose plans that provide for the acceleration of vesting of equity awards even in situations where an actual change of control may not occur. We encourage companies to structure their change of control provisions to require the termination of the covered employee before acceleration or special payments are triggered (commonly referred to as "double trigger" change of control provisions).

A-34

Golden parachutes

We generally view golden parachutes as encouragement to management to consider transactions that might be beneficial to shareholders. However, a large potential payout under a golden parachute arrangement also presents the risk of motivating a management team to support a sub-optimalsale price for a company.

When determining whether to support or oppose an advisory vote on a golden parachute plan, BIS may consider several factors, including:

We may support shareholder proposals requesting that implementation of such arrangements require shareholder approval.

Option exchanges

There may be legitimate instances where underwater options create an overhang on a company's capital structure and a repricing or option exchange may be warranted. We will evaluate these instances on a case-by-casebasis. BIS may support a request to reprice or exchange underwater options under the following circumstances:

Supplemental executive retirement plans

BIS may support shareholder proposals requesting to put extraordinary benefits contained in supplemental executive retirement plans("SERP") to a shareholder vote unless the company's executive pension plans do not contain excessive benefits beyond what is offered under employee-wide plans.

A-35

Material sustainability-related risks and opportunities

It is our view that well-runcompanies, where appropriate, effectively evaluate and manage material sustainability-related risks and opportunities²⁵ as a core component of their long-term value creation for shareholder and business strategy. At the board level, appropriate governance structures and responsibilities allow for effective oversight of the strategic implementation of material sustainability issues.

When assessing how to vote- including on the election of directors and relevant shareholder proposals - robust disclosures are essential for investors to understand, where appropriate, how companies are integrating material sustainability risks and opportunities across their business and strategic, long-term planning. Where a company has failed to appropriately provide robust disclosures and evidence of effective business practices, BIS may express concerns through our engagement and voting. As part of this consideration, we encourage companies to produce sustainability-related disclosures sufficiently in advance of their annual meeting so that the disclosures can be considered in relevant vote decisions.

We encourage disclosures aligned with the reporting framework developed by the Task Force on Climate-related Financial Disclosures (TCFD), supported by industry-specific metrics, such as those identified by the Sustainability Accounting Standards Board (SASB), now part of the International Sustainability Standards Board (ISSB) under the International Financial Reporting Standards (IFRS) Foundation.²⁶ While the TCFD framework was developed to support climate-related risk disclosures, the four pillars of the TCFD - governance, strategy, risk management, and metrics and targets - are a useful way for companies to disclose how they identify, assess, manage, and oversee a variety of sustainability-related risks and opportunities. SASB's²⁷ industry-specific metrics are beneficial in helping companies identify key performance indicators ("KPIs") across various dimensions of sustainability that are considered to be financially material. We recognize that some companies may report using different standards, which may be required by regulation, or one of a number of private standards. In such cases, we ask that companies highlight the metrics that are industry- or company-specific.

A-36

We look to companies to:

Companies should also disclose any material supranational standards adopted, the industry initiatives in which they participate, any peer group benchmarking undertaken, and any assurance processes to help investors understand their approach to sustainable and responsible business conduct.

Climate risk

It is our view that climate change has become a key factor in many companies' long-term prospects. As such, as long-term investors, we are interested in understanding how companies may be impacted by material climate-related risks and opportunities-just as we seek to understand other business-relevant risks and opportunities-and how these factors are considered within their strategy in a manner that is consistent with the company's business model and sector. Specifically, we look for companies to disclose strategies that they have in place that mitigate and are resilient to any material risks to their long-term business model associated with a range of climate-related scenarios, including a scenario in which global warming is limited to well below 2°C, and considering global ambitions to achieve a limit of 1.5°C.²⁸ It is, of course, up to each company to define their own strategy: that is not the role of BlackRock or other investors.

BIS recognizes that climate change can be challenging for many companies, as they seek to drive long-term value by mitigating risks and capturing opportunities. A growing number of companies, financial institutions, as well as governments, have committed to advancing decarbonization in line with the Paris Agreement. There is growing consensus that companies can benefit from the more favorable macro-economic environment under an orderly, timely, and equitable global energy transition.²⁹ Yet, the path ahead is deeply uncertain and uneven, with different parts of the economy moving at different speeds.³⁰ Many companies are asking what their role should be in contributing to an orderly and equitable transition-in ensuring a reliable energy supply and energy security and in protecting the most vulnerable from energy price shocks and economic dislocation. In this context, we encourage companies to include in their disclosures a business plan for how they intend to deliver long-term financial performance through a transition to global net zero carbon emissions, consistent with their business model and sector.

We look to companies to disclose short-, medium-, and long-term targets, ideally science-based targets where these are available for their sector, for Scope 1 and 2 greenhouse gas emissions(GHG)

A-37

reductions and to demonstrate how their targets are consistent with the long-term economic interests of their shareholders. Many companies have an opportunity to use and contribute to the development of low carbon energy sources and technologies that will be essential to decarbonizing the global economy over time. We also recognize that continued investment in traditional energy sources, including oil and gas, is required to maintain an orderly and equitable transition-and that divestiture of carbon-intensive assets is unlikely to contribute to global emissions reductions. We encourage companies to disclose how their capital allocation to various energy sources is consistent with their strategy.

At this stage, we view Scope 3 emissions differently from Scopes 1 and 2, given methodological complexity, regulatory uncertainty, concerns about double-counting, and lack of direct control by companies. While we welcome any disclosures and commitments companies choose to make regarding Scope 3 emissions, we recognize that these are provided on a good-faith basis as methodology develops. Our publicly available commentary provides more information on our approach to climate risk and the global energy transition.

Natural capital

The management of nature-related factors is increasingly a core component of some companies' ability to generate sustainable, long-term financial returns for shareholders, particularly where a company's strategy is heavily reliant on the availably of natural capital, or whose supply chains are exposed to locations with nature-related risks. We look for such companies to disclose³¹ how they consider their reliance and use of natural capital, including appropriate risk oversight and relevant metrics and targets, to understand how these factors are integrated into strategy. We will evaluate these disclosures to inform our view of how a company is managing material nature-related risks and opportunities, as well as in our assessment of relevant shareholder proposals. Our publicly available commentary provides more information on our approach to natural capital.

Key stakeholder interests

In order to deliver long-term value for shareholders, companies should also consider the interests of their key stakeholders. While stakeholder groups may vary across industries, they are likely to include employees; business partners (such as suppliers and distributors); clients and consumers; government and regulators; and the constituents of the communities in which a company operates. Companies that build strong relationships with their key stakeholders are more likely to meet their own strategic objectives, while poor relationships may create adverse impacts that expose a company to legal, regulatory, operational, and reputational risks.

Companies should effectively oversee and mitigate material risks related to stakeholders with appropriate due diligence processes and board oversight. Where we determine that company is not appropriately considering their key stakeholder interests in a way that poses material financial risk to the company and its shareholders, we may vote against relevant directors or support shareholder proposals related to these topics. Our publicly available commentary provides more information on our approach.

Conversely, we note that some shareholder proposals seek to address topics that are clearly within the purview of certain stakeholders. For example, we recognize that topics around taxation and tax reporting are within the domain of local, state, and federal authorities. BIS will generally not support these proposals.

A-38

Human capital management

A company's approach to human capital management ("HCM") is a critical factor in fostering an inclusive, diverse, and engaged workforce, which contributes to business continuity, innovation, and long-term value creation. Consequently, we ask companies to demonstrate a robust approach to HCM and provide shareholders with disclosures to understand how their approach aligns with their stated strategy and business model.

Clear and consistent disclosures on these matters are critical for investors to make an informed assessment of a company's HCM practices. Companies should disclose the steps they are taking to advance diversity, equity, and inclusion; job categories and workforce demographics; and their responses to the U.S. Equal Employment Opportunity Commission's EEO-1Survey. Where we believe a company's disclosures or practices fall short relative to the market or peers, or we are unable to ascertain the board and management's effectiveness in overseeing related risks and opportunities, we may vote against members of the appropriate committee or support relevant shareholder proposals. Our publicly available commentary provides more information on our approach to HCM.

Corporate political activities

Companies may engage in certain political activities, within legal and regulatory limits, in order to support public policy matters material to the companies' long-term strategies. These activities can also create risks, including: the potential for allegations of corruption; certain reputational risks; and risks that arise from the complex legal, regulatory, and compliance considerations associated with corporate political spending and lobbying activity. Companies that engage in political activities should develop and maintain robust processes to guide these activities and mitigate risks, including board oversight.

We depend on companies to provide accessible and clear disclosures so that investors can easily understand how their political activities support their long-term strategy, including on stated public policy priorities. When presented with shareholder proposals requesting increased disclosure on corporate political activities, BIS will evaluate publicly available information to consider how a company's lobbying and political activities may impact the company. We will also evaluate whether there is general consistency between a company's stated positions on policy matters material to their strategy and the material positions taken by significant industry groups of which they are a member. We may decide to support a shareholder proposal requesting additional disclosures if we identify a material inconsistency or feel that further transparency may clarify how the company's political activities support its long-term strategy. Our publicly available commentary provides more information on our approach to corporate political activities.

General corporate governance matters

IPO governance

Boards should disclose how the corporate governance structures adopted upon a company's initial public offering ("IPO") are in shareholders' best long-term interests. We also ask boards to conduct a regular review of corporate governance and control structures, such that boards might evolve foundational corporate governance structures as company circumstances change, without undue costs and disruption to shareholders. In our letter on unequal voting structures, we articulate our view that "one vote for one share" is the preferred structure for publicly-traded companies. We also recognize the potential benefits of dual class shares to newly public companies as they establish themselves; however, these structures should have a specific and limited duration. We will generally engage new companies on topics such as classified boards and supermajority vote provisions to amend bylaws, as we think that such arrangements may not be in the best interests of shareholders over the long-term.

A-39

We may apply a one-yeargrace period for the application of certain director-related guidelines (including, but not limited to, responsibilities on other public company boards and board composition concerns), during which we ask boards to take steps to bring corporate governance standards in line with our policies.

Further, if a company qualifies as an emerging growth company (an "EGC") under the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act"), we will give consideration to the NYSE and NASDAQ governance exemptions granted under the JOBS Act for the duration such a company is categorized as an EGC. An EGC should have an independent audit committee by the first anniversary of its IPO, with our standard approach to voting on auditors and audit-related issues applicable in full for an EGC on the first anniversary of its IPO.

Corporate form

Proposals to change a corporation's form, including those to convert to a public benefit corporation ("PBC") structure, should clearly articulate the stakeholder groups the company seeks to benefit and provide detail on how the interests of shareholders would be augmented or adversely affected with the change to a PBC. These disclosures should also include the accountability and voting mechanisms that would be available to shareholders. We generally support management proposals to convert to a PBC if our analysis indicates that shareholders' interests are adequately protected. Corporate form shareholder proposals are evaluated on a case-by-casebasis.

Exclusive forum provisions

BIS generally supports proposals to seek exclusive forum for certain shareholder litigation. In cases where a board unilaterally adopts exclusive forum provisions that we consider unfavorable to the interests of shareholders, we will vote against the Independent Chair or Lead Independent director and members of the nominating/governance committee.

Reincorporation

We will evaluate the economic and strategic rationale behind the company's proposal to reincorporate on a case-by-casebasis. In all instances, we will evaluate the changes to shareholder protections under the new charter/articles/bylaws to assess whether the move increases or decreases shareholder protections. Where we find that shareholder protections are diminished, we may support reincorporation if we determine that the overall benefits outweigh the diminished rights.

Multi-jurisdictional companies

Where a company is listed on multiple exchanges or incorporated in a country different from their primary listing, we will seek to apply the most relevant market guideline(s) to our analysis of the company's governance structure and specific proposals on the shareholder meeting agenda. In doing so, we typically consider the governance standards of the company's primary listing, the market standards by which the company governs themselves, and the market context of each specific proposal on the agenda. If the relevant standards are silent on the issue under consideration, we will use our professional judgment as to what voting outcome would best protect the long-term economic interests of investors. Companies should disclose the rationale for their selection of primary listing, country of incorporation, and choice of governance structures, particularly where there is conflict between relevant market governance practices.

A-40

Adjourn meeting to solicit additional votes

We generally support such proposals unless the agenda contains items that we judge to be detrimental to shareholders' best long-term economic interests.

Bundled proposals

Shareholders should have the opportunity to review substantial governance changes individually without having to accept bundled proposals. Where several measures are grouped into one proposal, BIS may reject certain positive changes when linked with proposals that generally contradict or impede the rights and economic interests of shareholders.

Other business

We oppose voting on matters where we are not given the opportunity to review and understand those measures and carry out an appropriate level of shareholder oversight.

Shareholder protections

Amendment to charter/articles/bylaws

Shareholders should have the right to vote on key corporate governance matters, including changes to governance mechanisms and amendments to the charter/articles/bylaws. We may vote against certain directors where changes to governing documents are not put to a shareholder vote within a reasonable period of time, particularly if those changes have the potential to impact shareholder rights (see "Director elections"). In cases where a board's unilateral adoption of changes to the charter/articles/bylaws promotes cost and operational efficiency benefits for the company and its shareholders, we may support such action if it does not have a negative effect on shareholder rights or the company's corporate governance structure.

When voting on a management or shareholder proposal to make changes to the charter/articles/bylaws, we will consider in part the company's and/or proponent's publicly stated rationale for the changes; the company's governance profile and history; relevant jurisdictional laws; and situational or contextual circumstances which may have motivated the proposed changes, among other factors. We will typically support amendments to the charter/articles/bylaws where the benefits to shareholders outweigh the costs of failing to make such changes.

Proxy access

It is our view that long-term shareholders should have the opportunity, when necessary and under reasonable conditions, to nominate directors on the company's proxy card.³² Securing the right of shareholders to nominate directors without engaging in a control contest can enhance shareholders' ability to meaningfully participate in the director election process, encourage board attention to shareholder interests, and provide shareholders an effective means of directing that attention where it is lacking. Proxy access mechanisms should provide shareholders with a reasonable opportunity to use this right without stipulating overly restrictive or onerous parameters for use, and also provide assurances that the mechanism will not be subject to abuse by short-term investors, investors without a substantial investment in the company, or investors seeking to take control of the board.

A-41

In general, we support market-standardized proxy access proposals, which allow a shareholder (or group of up to 20 shareholders) holding three percent of a company's outstanding shares for at least three years the right to nominate the greater of up to two directors or 20% of the board. Where a standardized proxy access provision exists, we will generally oppose shareholder proposals requesting outlier thresholds.

Right to act by written consent

In exceptional circumstances and with sufficiently broad support, shareholders should have the opportunity to raise issues of substantial importance without having to wait for management to schedule a meeting. Accordingly, shareholders should have the right to solicit votes by written consent provided that: 1) there are reasonable requirements to initiate the consent solicitation process(in order to avoid the waste of corporate resources in addressing narrowly supported interests); and 2) shareholders receive a minimum of 50% of outstanding shares to effectuate the action by written consent.

We may oppose shareholder proposals requesting the right to act by written consent in cases where the proposal is structured for the benefit of a dominant shareholder to the exclusion of others, or if the proposal is written to discourage the board from incorporating appropriate mechanisms to avoid the waste of corporate resources when establishing a right to act by written consent. Additionally, we may oppose shareholder proposals requesting the right to act by written consent if the company already provides a shareholder right to call a special meeting that offers shareholders a reasonable opportunity to raise issues of substantial importance without having to wait for management to schedule a meeting.

Right to call a special meeting

In exceptional circumstances and with sufficiently broad support, shareholders should have the opportunity to raise issues of substantial importance without having to wait for management to schedule a meeting. Accordingly, shareholders should have the right to call a special meeting in cases where a reasonably high proportion of shareholders (typically a minimum of 15% but no higher than 25%) are required to agree to such a meeting before it is called. However, we may oppose this right in cases where the proposal is structured for the benefit of a dominant shareholder, or where a lower threshold may lead to an ineffective use of corporate resources. We generally think that a right to act via written consent is not a sufficient alternative to the right to call a special meeting.

Consent solicitation

While BlackRock is supportive of the shareholder rights to act by written consent and call a special meeting, BlackRock is subject to certain regulations and laws that place restrictions and limitations on how BlackRock can interact with the companies in which we invest on behalf of our clients, including our ability to participate in consent solicitations. As a result, BlackRock will generally not participate in consent solicitations or related processes. However, once an item comes to a shareholder vote, we uphold our fiduciary duty to vote in the best long-term interests of our clients, where we are authorized to do so.

Simple majority voting

We generally favor a simple majority voting requirement to pass proposals. Therefore, we will generally support the reduction or the elimination of supermajority voting requirements to the extent that we determine shareholders' ability to protect their economic interests is improved. Nonetheless, in

A-42

situations where there is a substantial or dominant shareholder, supermajority voting may be protective of minority shareholder interests, and we may support supermajority voting requirements in those situations.

Virtual meetings

Shareholders should have the opportunity to participate in the annual and special meetings for the companies in which they are invested, as these meetings facilitate an opportunity for shareholders to provide feedback and hear from the board and management. While these meetings have traditionally been conducted in-person,virtual meetings are an increasingly viable way for companies to utilize technology to facilitate shareholder accessibility, inclusiveness, and cost efficiencies. Shareholders should have a meaningful opportunity to participate in the meeting and interact with the board and management in these virtual settings; companies should facilitate open dialogue and allow shareholders to voice concerns and provide feedback without undue censorship. Relevant shareholder proposals are assessed on a case-by-casebasis.

A-43

APPENDIX B - Description of Bond Ratings

A rating is generally assigned to a fixed-income security at the time of issuance by a credit rating agency designated as a nationally recognized statistical rating organization ("NRSRO") by the SEC. While NRSROs may from time to time revise such ratings, they undertake no obligation to do so, and the ratings given to securities at issuance do not necessarily represent ratings which would be given to these securities on a particular subsequent date.

NRSROs may rate specific investments (e.g., bonds), issuers (e.g., corporations, governments and financial institutions) and/or programs (e.g., commercial paper programs). However, certain types of investments may not be rated by NRSROs, such as certain government/sovereign obligations, US agency securities, commercial paper, time deposits at financial institutions, and derivative instruments such as credit default swaps. For these types of investments, as well as US Treasury securities (some of which are not rated), where a NRSRO has not rated the specific investment but has rated the investment's issuer, program, financial institution or underlying reference asset, BlackRock Advisors, LLC, BlackRock Fund Advisors or their respective affiliates ("BlackRock") may consider the investment to have the same NRSRO rating as its issuer, program, financial institution or underlying reference asset, as applicable. In the case of municipal securities, where one NRSRO provides multiple ratings for the same security (e.g., "underlying," "insured" and/or "enhanced" ratings), BlackRock may consider the security to have the highest of the multiple ratings.

New issue securities (regardless of type) may not be rated by a NRSRO at the time of their initial offering. Preliminary prospectuses or term sheets for new issue securities may include an expected rating for the security (as determined by the underwriter and/or issuer) or a NRSRO rating for the issuer of the security. If applicable, when deciding whether to purchase a new issue security that has not yet been rated by a NRSRO, BlackRock may attribute an expected rating to the security based on: (i) the expected rating of the security set forth in the preliminary prospectus or term sheet for the security; (ii) the NRSRO's rating for the issuer of the security set forth in the preliminary prospectus or term sheet for the security; or (iii) with respect to asset-backed securities, the rating of a prior issuance having a similar structure or the same sponsor.

Where the investment objective of a fund is to track the performance of an index that includes credit ratings eligibility criteria as part of its index methodology, the fund may purchase any security within the index, such security having been determined by the index provider as meeting its credit ratings eligibility criteria. The credit ratings practices of an index provider may differ from BlackRock's practices, as described above. Further, the fund may invest, directly or indirectly, in securities that are not rated by a rating agency or securities with a credit rating that differs from the credit rating specified in its index methodology in various circumstances, including where a security is downgraded but not yet removed from an index, following the removal of a security from an index prior to its sale by the fund or as a result of a corporate action or restructuring affecting an issuer of a security held by the fund.

Fixed-income securities which are unrated may expose the investor to risks with respect to capacity to pay interest or repay principal which are similar to the risks of lower-rated speculative bonds. Evaluation of these securities is dependent on BlackRock's judgment, analysis and experience in the evaluation of such securities.

Investors should note that the assignment of a rating to a security by an NRSRO may not reflect the effect of recent developments on the issuer's ability to make interest and principal payments or on the likelihood of default.

Securities deemed to be high yield are rated below Baa3 by Moody's and below BBB-by S&P Global Ratings and Fitch.

The descriptions below relate to general long-term and short-term obligations of an issuer.

A Description of Moody's Investors Service, Inc.'s ("Moody's") Global Rating Scales

Ratings assigned on Moody's global long-term and short-term rating scales are forward-looking opinions of the relative credit risks of financial obligations issued by non-financialcorporates, financial institutions, structured finance vehicles, project finance vehicles, and public sector entities. Moody's defines credit risk as the risk that an entity may not meet its contractual financial obligations as they come due and any estimated financial loss in the event of default or impairment. The contractual financial obligations addressed by Moody's ratings are those that call for, without regard to enforceability, the payment of an ascertainable amount, which may vary based upon standard sources of variation (e.g., floating interest rates), by an ascertainable date. Moody's rating addresses the issuer's ability to obtain cash sufficient to service the obligation, and its willingness to pay. Moody's ratings do not address non-standardsources of variation in the amount of the principal obligation (e.g., equity indexed), absent an express statement to the contrary in a press release accompanying an initial rating. Long-term ratings are assigned to issuers or obligations with an original maturity of one year or more and reflect both on the likelihood of a default or impairment on contractual financial obligations and the expected financial loss suffered in the event of default or impairment. Short-term ratings are assigned for obligations with an original maturity of thirteen months or less and reflect both on the likelihood of a default or impairment on contractual financial obligations and the expected financial loss suffered in the event of default or impairment. Moody's issues ratings at the issuer level and instrument level on both the long-term scale and the short-term scale. Typically, ratings are made publicly available although private and unpublished ratings may also be assigned.

Moody's differentiates structured finance ratings from fundamental ratings (i.e., ratings on nonfinancial corporate, financial institution, and public sector entities) on the global long-term scale by adding (sf) to all structured finance ratings. The addition of (sf) to structured finance ratings should eliminate any presumption that such ratings and fundamental ratings at the same letter grade level will behave the same. The (sf) indicator for structured finance security ratings indicates that otherwise similarly rated structured finance and fundamental securities may have different risk characteristics. Through its current methodologies, however, Moody's aspires to achieve broad expected equivalence in structured finance and fundamental rating performance when measured over a long period of time.

Description of Moody's Global Long-Term Rating Scale

B-2

Note: Moody's appends numerical modifiers 1, 2, and 3 to each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-rangeranking; and the modifier 3 indicates a ranking in the lower end of that generic rating category. Additionally, a "(hyb)" indicator is appended to all ratings of hybrid securities issued by banks, insurers, finance companies, and securities firms.

By their terms, hybrid securities allow for the omission of scheduled dividends, interest, or principal payments, which can potentially result in impairment if such an omission occurs. Hybrid securities may also be subject to contractually allowable write-downs of principal that could result in impairment. Together with the hybrid indicator, the long-term obligation rating assigned to a hybrid security is an expression of the relative credit risk associated with that security.

Description of Moody's U.S. Municipal Short-Term Debt and Demand Obligation Ratings

Description of Moody's Short-Term Obligation Ratings

Moody's uses the global short-term Prime rating scale for commercial paper issued by U.S. municipalities and nonprofits. These commercial paper programs may be backed by external letters of credit or liquidity facilities, or by an issuer's self-liquidity.

For other short-term municipal obligations, Moody's uses one of two other short-term rating scales, the Municipal Investment Grade ("MIG") and Variable Municipal Investment Grade ("VMIG") scales discussed below.

Moody's uses the MIG scale for U.S. municipal cash flow notes, bond anticipation notes and certain other short-term obligations, which typically mature in three years or less. Under certain circumstances, Moody's uses the MIG scale for bond anticipation notes with maturities of up to five years.

MIG Scale

B-3

Description of Moody's Demand Obligation Ratings

In the case of variable rate demand obligations ("VRDOs"), a two-componentrating is assigned. The components are a long-term rating and a short-term demand obligation rating. The long-term rating addresses the issuer's ability to meet scheduled principal and interest payments. The short-term demand obligation rating addresses the ability of the issuer or the liquidity provider to make payments associated with the purchase-price-upon-demand feature ("demand feature") of the VRDO. The short-term demand obligation rating uses the VMIG scale. VMIG ratings with liquidity support use as an input the short-term Counterparty Risk Assessment of the support provider, or the long-term rating of the underlying obligor in the absence of third party liquidity support. Transitions of VMIG ratings of demand obligations with conditional liquidity support differ from transitions on the Prime scale to reflect the risk that external liquidity support will terminate if the issuer's long-term rating drops below investment grade.

Moody's typically assigns the VMIG short-term demand obligation rating if the frequency of the demand feature is less than every three years. If the frequency of the demand feature is less than three years but the purchase price is payable only with remarketing proceeds, the short-term demand obligation rating is "NR".

VMIG Scale

Description of S&P Global Ratings ("S&P"), a Division of S&P Global Inc., Issue Credit Ratings

An S&P issue credit rating is a forward-looking opinion about the creditworthiness of an obligor with respect to a specific financial obligation, a specific class of financial obligations, or a specific financial program (including ratings on medium-term note programs and commercial paper programs). It takes into consideration the creditworthiness of guarantors, insurers, or other forms of credit enhancement on the obligation and takes into account the currency in which the obligation is denominated. The opinion reflects S&P's view of the obligor's capacity and willingness to meet its financial commitments as they come due, and this opinion may assess terms, such as collateral security and subordination, which could affect ultimate payment in the event of default.

Issue credit ratings can be either long-term or short-term. Short-term issue credit ratings are generally assigned to those obligations considered short-term in the relevant market, typically with an original maturity of no more than 365 days. Short-term issue credit ratings are also used to indicate the creditworthiness of an obligor with respect to put features on long-term obligations. S&P would typically assign a long-term issue credit rating to an obligation with an original maturity of greater than 365 days.

B-4

However, the ratings S&P assigns to certain instruments may diverge from these guidelines based on market practices. Medium-term notes are assigned long-term ratings.

Issue credit ratings are based, in varying degrees, on S&P's analysis of the following considerations:

An issue rating is an assessment of default risk but may incorporate an assessment of relative seniority or ultimate recovery in the event of default. Junior obligations are typically rated lower than senior obligations, to reflect lower priority in bankruptcy, as noted above. (Such differentiation may apply when an entity has both senior and subordinated obligations, secured and unsecured obligations, or operating company and holding company obligations.)

Description of S&P's Municipal Short-Term Note Ratings

An S&P U.S. municipal note rating reflects S&P's opinion about the liquidity factors and market access risks unique to the notes. Notes due in three years or less will likely receive a note rating. Notes with an original maturity of more than three years will most likely receive a long-term debt rating. In determining which type of rating, if any, to assign, S&P's analysis will review the following considerations:

S&P's municipal short-term note rating symbols are as follows:

Description of Fitch Ratings' ("Fitch's") Credit Ratings Scales

Fitch Ratings publishes opinions on a variety of scales. The most common of these are credit ratings, but the agency also publishes ratings, scores and other relative opinions relating to financial or operational strength. For example, Fitch also provides specialized ratings of servicers of residential and commercial mortgages, asset managers and funds. In each case, users should refer to the definitions of each individual scale for guidance on the dimensions of risk covered in each assessment.

Fitch's credit ratings relating to issuers are an opinion on the relative ability of an entity to meet financial commitments, such as interest, preferred dividends, repayment of principal, insurance claims or counterparty obligations. Credit ratings relating to securities and obligations of an issuer can include a recovery expectation. Credit ratings are used by investors as indications of the likelihood of receiving the money owed to them in accordance with the terms on which they invested. The agency's credit ratings cover the global spectrum of corporate, sovereign financial, bank, insurance, and public finance entities (including supranational and sub-nationalentities) and the securities or other obligations they issue, as well as structured finance securities backed by receivables or other financial assets.

The terms "investment grade" and "speculative grade" have established themselves over time as shorthand to describe the categories 'AAA' to 'BBB' (investment grade) and 'BB' to 'D' (speculative grade). The terms investment grade and speculative grade are market conventions and do not imply any recommendation or endorsement of a specific security for investment purposes. Investment grade categories indicate relatively low to moderate credit risk, while ratings in the speculative categories either signal a higher level of credit risk or that a default has already occurred.

For the convenience of investors, Fitch may also include issues relating to a rated issuer that are not and have not been rated on its web page. Such issues are also denoted as 'NR'.

B-7

Credit ratings express risk in relative rank order, which is to say they are ordinal measures of credit risk and are not predictive of a specific frequency of default or loss. For information about the historical performance of ratings please refer to Fitch's Ratings Transition and Default studies which detail the historical default rates and their meaning. The European Securities and Markets Authority also maintains a central repository of historical default rates.

Fitch's credit ratings do not directly address any risk other than credit risk. In particular, ratings do not deal with the risk of a market value loss on a rated security due to changes in interest rates, liquidity and other market considerations. However, in terms of payment obligation on the rated liability, market risk may be considered to the extent that it influences the ability of an issuer to pay upon a commitment.

Ratings nonetheless do not reflect market risk to the extent that they influence the size or other conditionality of the obligation to pay upon a commitment (for example, in the case of index-linked bonds).

In the default components of ratings assigned to individual obligations or instruments, the agency typically rates to the likelihood of non-paymentor default in accordance with the terms of that instrument's documentation. In limited cases, Fitch may include additional considerations (i.e. rate to a higher or lower standard than that implied in the obligation's documentation).

The primary credit rating scales can be used to provide a rating of privately issued obligations or certain note issuance programs or for private ratings. In this case the rating is not published, but only provided to the issuer or its agents in the form of a rating letter.

The primary credit rating scales may also be used to provide ratings for a more narrow scope, including interest strips and return of principal or in other forms of opinions such as credit opinions or rating assessment services. Credit opinions are either a notch- or category-specific view using the primary rating scale and omit one or more characteristics of a full rating or meet them to a different standard. Credit opinions will be indicated using a lower case letter symbol combined with either an '*' (e.g. 'bbb+*') or (cat) suffix to denote the opinion status. Credit opinions will be point-in-timetypically but may be monitored if the analytical group believes information will be sufficiently available. Rating assessment services are a notch-specific view using the primary rating scale of how an existing or potential rating may be changed by a given set of hypothetical circumstances. While credit opinions and rating assessment services are point-in-timeand are not monitored, they may have a directional watch or outlook assigned, which can signify the trajectory of the credit profile.

Description of Fitch's Long-Term Corporate Finance Obligations Rating Scales

Ratings of individual securities or financial obligations of a corporate issuer address relative vulnerability to default on an ordinal scale. In addition, for financial obligations in corporate finance, a measure of recovery given default on that liability is also included in the rating assessment. This notably applies to covered bonds ratings, which incorporate both an indication of the probability of default and of the recovery given a default of this debt instrument. On the contrary, Ratings of debtor-in-possession("DIP") obligations incorporate the expectation of full repayment.

The relationship between the issuer scale and obligation scale assumes a generic historical average recovery. Individual obligations can be assigned ratings higher, lower, or the same as that entity's issuer rating or issuer default rating ("IDR"), based on their relative ranking, relative vulnerability to default or based on explicit Recovery Ratings.

B-8

As a result, individual obligations of entities, such as corporations, are assigned ratings higher, lower, or the same as that entity's issuer rating or IDR, except DIP obligation ratings that are not based off an IDR. At the lower end of the ratings scale, Fitch publishes explicit Recovery Ratings in many cases to complement issuer and obligation ratings.

Fitch long-term obligations rating scales are as follows:

Within rating categories, Fitch may use modifiers. The modifiers "+" or "-" may be appended to a rating to denote relative status within major rating categories.

For example, the rating category 'AA' has three notch-specific rating levels ('AA+'; 'AA'; 'AA-'; each a rating level). Such suffixes are not added to 'AAA' ratings and ratings below the 'CCC' category. For the short-term rating category of 'F1', a '+' may be appended.

Description of Fitch's Short-Term Ratings Assigned to Issuers and Obligations

A short-term issuer or obligation rating is based in all cases on the short-term vulnerability to default of the rated entity and relates to the capacity to meet financial obligations in accordance with the documentation governing the relevant obligation. Short-term deposit ratings may be adjusted for loss severity. Short-term ratings are assigned to obligations whose initial maturity is viewed as "short term" based on market convention. Typically, this means up to 13 months for corporate, sovereign, and structured obligations and up to 36 months for obligations in U.S. public finance markets.
