Principal at Risk Securities Linked to the Lowest Performing of the S&P 500^® Index, the Russell 2000^® Index and the Nasdaq-100^® Index due April 29, 2027

The Securities are not appropriate for all investors. The Securities may be an appropriate investment for investors who:

■ seek an investment with Contingent Coupon Payments at a rate of 7.80% per annum until the earlier of the Maturity Date or optional redemption, if, and only if, the closing level of the Lowest Performing Underlying on each Eligible Trading Day during an Observation Period is greater than or equal to 70% of its Starting Value;

■ understand that they will not receive a Contingent Coupon Payment with respect to an Observation Period if the closing level of the Lowest Performing Underlying on any Eligible Trading Day during that Observation Period is less than its Coupon Barrier, even if the closing level of that Underlying is greater than or equal to its Coupon Barrier on every other Eligible Trading Day during that Observation Period and even if the better performing Underlyings perform favorably.

■ understand that if the Ending Value of the Lowest Performing Underlying on the Final Calculation Day has declined by more than 40% from its Starting Value, they will be fully exposed to the decline in the Lowest Performing Underlying from its Starting Value and will lose more than 40%, and possibly all, of the principal amount of their Securities at maturity;

■ are willing to accept the risk that they may receive few or no Contingent Coupon Payments over the term of the Securities;

■ understand that we may redeem the Securities prior to the Maturity Date at our option beginning approximately three months after issuance, that the term of the Securities may be as short as approximately three months, and that it is more likely that we will redeem the Securities when it would otherwise be advantageous for you to continue to hold the Securities;

■ understand that the return on the Securities will depend solely on the performance of the Underlying that is the Lowest Performing Underlying on each Eligible Trading Day during each Observation Period (including the Final Calculation Day) and that they will not benefit in any way from the performance of the better performing Underlyings;

■ understand that the Securities are riskier than alternative investments linked to only one of the Underlyings or linked to a basket composed of each Underlying;

■ understand and are willing to accept the full downside risks of each Underlying;

■ are willing to forgo participation in any appreciation of any Underlying and dividends on securities included in the Underlyings; and

■ are willing to hold the Securities until maturity.

The Securities may not be an appropriate investment for investors who:

■ seek a liquid investment or are unable or unwilling to hold the Securities to maturity;

■ require full payment of the principal amount of the Securities at maturity;

■ seek a security with a fixed term;

■ are unwilling to purchase Securities with an estimated value as of the Pricing Date that is lower than the public offering price set forth on the cover page of this pricing supplement;

■ are unwilling to accept the risk that the closing level of the Lowest Performing Underlying on the Final Calculation Day may decline by more than 40% from its Starting Value;

■ seek certainty of current income over the term of the Securities;

■ seek exposure to the upside performance of any or each Underlying;

■ seek exposure to a basket composed of each Underlying or a similar investment in which the overall return is based on a blend of the performances of the Underlyings, rather than solely on the Lowest Performing Underlying;

■ are unwilling to accept the risk of exposure to the Underlyings;

■ are unwilling to accept the credit risk of BofA Finance, as issuer, and BAC, as guarantor, to obtain exposure to the Underlyings generally, or to obtain exposure to the Underlyings that the Securities provide specifically; or

■ prefer the lower risk of conventional fixed income investments with comparable maturities issued by companies with comparable credit ratings.

The considerations identified above are not exhaustive. Whether or not the Securities are an appropriate investment for you will depend on your individual circumstances, and you should reach an investment decision only after you and your investment, legal, tax, accounting and other advisors have carefully considered the appropriateness of an investment in the Securities in light of your particular circumstances. You should also review carefully "Selected Risk Considerations" herein and "Risk Factors" in each of the accompanying product supplement, prospectus supplement and prospectus for risks related to an investment in the Securities. For more information about the Underlyings, please see the sections titled "The S&P 500^® Index," "The Russell 2000^® Index" and "The Nasdaq-100^® Index" below.

Unless we have previously redeemed the Securities at our option, on each Contingent Coupon Payment Date, either you will receive a Contingent Coupon Payment or you will not receive a Contingent Coupon Payment, depending on the closing level of the Lowest Performing Underlying on each Eligible Trading Day during the related Observation Period.

Step 1: Determine which Underlying is the Lowest Performing Underlying on each Eligible Trading Day during the related Observation Period. The Lowest Performing Underlying on any Eligible Trading Day during an Observation Period is the Underlying with the lowest Performance Factor on that date. The Performance Factor of an Underlying on any Eligible Trading Day during an Observation Period is its closing level on that date as a percentage of its Starting Value (i.e., its closing level on that date divided by its Starting Value).

Step 2: Determine whether a Contingent Coupon Payment is paid on the applicable Contingent Coupon Payment Date based on the closing level of the Lowest Performing Underlying on each Eligible Trading Day during the related Observation Period, as follows:

If we have not previously redeemed the Securities prior to the Maturity Date at our option, then at maturity you will receive (in addition to the final Contingent Coupon Payment, if otherwise payable) a cash payment per Security (the Maturity Payment Amount) calculated as follows:

Step 1: Determine which Underlying is the Lowest Performing Underlying on the Final Calculation Day. The Lowest Performing Underlying on the Final Calculation Day is the Underlying with the lowest Performance Factor on the Final Calculation Day. The Performance Factor of an Underlying on the Final Calculation Day is its Ending Value as a percentage of its Starting Value (i.e., its Ending Value divided by its Starting Value).

Step 2: Calculate the Maturity Payment Amount based on the Ending Value of the Lowest Performing Underlying, as follows:

The following profile illustrates the potential Maturity Payment Amount on the Securities (excluding the final Contingent Coupon Payment, if any) for a range of hypothetical performances of the Lowest Performing Underlying on the Final Calculation Day from its Starting Value to its Ending Value, assuming the Securities have not been redeemed prior to the Maturity Date. As this profile illustrates, in no event will you have a positive rate of return based solely on the Maturity Payment Amount received at maturity; any positive return will be based solely on the Contingent Coupon Payments, if any, received during the term of the Securities. This graph has been prepared for purposes of illustration only. Your actual return will depend on the actual Ending Value of the Lowest Performing Underlying on the Final Calculation Day and whether you hold your Securities to the Maturity Date. The performance of the better performing Underlyings is not relevant to your return on the Securities.

The Securities have complex features and investing in the Securities will involve risks not associated with an investment in conventional debt securities. Your decision to purchase the Securities should be made only after carefully considering the risks of an investment in the Securities, including those discussed below, with your advisors in light of your particular circumstances. The Securities are not an appropriate investment for you if you are not knowledgeable about significant elements of the Securities or financial matters in general. You should carefully review the more detailed explanation of risks relating to the Securities in the "Risk Factors" sections beginning on page PS-5 of the accompanying product supplement, page S-6 of the accompanying prospectus supplement and page 7 of the accompanying prospectus.

Structure-related Risks

Your investment may result in a loss; there is no guaranteed return of principal. There is no fixed principal repayment amount on the Securities at maturity. If we do not redeem the Securities prior to maturity and the Ending Value of any Underlying is less than its Threshold Value, at maturity you will lose 1% of the principal amount for each 1% that the Ending Value of the Lowest Performing Underlying is less than its Starting Value. In that case, you will lose a significant portion or all of your investment in the Securities.

Your return on the Securities is limited to the return represented by the Contingent Coupon Payments, if any, over the term of the Securities. Your return on the Securities is limited to the Contingent Coupon Payments paid over the term of the Securities, regardless of the extent to which the closing level of any Underlying on any Eligible Trading Day during the Observation Periods or the Ending Value of any Underlying exceeds its Coupon Barrier or Starting Value, as applicable. Similarly, the amount payable at maturity or upon early redemption will never exceed the sum of the principal amount and the applicable Contingent Coupon Payment, regardless of the extent to which the closing level of any Underlying on any Eligible Trading Day during an Observation Period exceeds its Starting Value. In contrast, a direct investment in the securities included in one or more of the Underlyings would allow you to receive the benefit of any appreciation in their values. Thus, any return on the Securities will not reflect the return you would realize if you actually owned those securities and received the dividends paid or distributions made on them.

The Securities are subject to a potential early redemption, which would limit your ability to receive the Contingent Coupon Payments over the full term of the Securities. On each Optional Redemption Date we may, at our option, redeem your Securities in whole, but not in part. If the Securities are redeemed prior to the Maturity Date, you will be entitled to receive the Stated Principal Amount plus any Contingent Coupon Payment otherwise due, and no further amounts will be payable on the Securities. In this case, you will lose the opportunity to continue to receive Contingent Coupon Payments after the date of the early redemption. If the Securities are redeemed prior to the Maturity Date, you may be unable to invest in other securities with a similar level of risk that could provide a return that is similar to the Securities. Even if we do not exercise our option to redeem your Securities, our ability to do so may adversely affect the market value of your Securities. It is our sole option whether to redeem your Securities prior to maturity on any Optional Redemption Date and we may or may not exercise this option for any reason. Because of this, the term of your Securities could be as short as approximately three months.

It is more likely that we will redeem the Securities in our sole discretion prior to maturity to the extent that the expected Contingent Coupon Payments payable on the Securities are greater than the coupon that would be payable on other instruments issued by us of comparable maturity, terms and credit rating trading in the market. The greater likelihood of us redeeming the Securities in that environment increases the risk that you will not be able to reinvest the proceeds from the redeemed Securities in another investment that provides a similar yield with a similar level of risk. We are less likely to redeem the Securities prior to maturity when the expected Contingent Coupon Payments payable on the Securities are less than the coupon that would be payable on other comparable instruments issued by us, which includes when the level of any of the Underlyings is less than its Coupon Barrier. Therefore, the Securities are more likely to remain outstanding when the expected Contingent Coupon Payments payable on the Securities are less than what would be payable on other comparable instruments and when your risk of not receiving a coupon is relatively higher.

You may not receive any Contingent Coupon Payments. The Securities do not provide for any regular fixed coupon payments. Investors in the Securities will not necessarily receive any Contingent Coupon Payments on the Securities. If the closing level of the Lowest Performing Underlying on any Eligible Trading Day during an Observation Period is less than its Coupon Barrier, no Contingent Coupon Payment will accrue or be payable on the related Coupon Payment Date. If the closing level of the Lowest Performing Underlying is less than its Coupon Barrier on at least one Eligible Trading Day during each Observation Period during the term of the Securities, you will not receive any Contingent Coupon Payments during the term of the Securities, and you will not receive a positive return on the Securities.

Because the Securities are linked to the lowest performing (and not the average performance) of the Underlyings, you may not receive any return on the Securities and may lose a significant portion or all of your principal amount even if the closing level of one Underlying is always greater than or equal to its Coupon Barrier or Threshold Value, as applicable. Your Securities are linked to the lowest performing of the Underlyings, and a change in the level of one Underlying may not correlate with changes in the level of the other Underlying(s). The Securities are not linked to a basket composed of the Underlyings, where the depreciation in the level of one Underlying could be offset to some extent by the appreciation in the level of the other Underlying(s). In the case of the Securities, the individual performance of each Underlying would not be combined, and the depreciation in the level of one Underlying would not be offset by any appreciation in the level of the other Underlying(s). Even if the closing level of an Underlying is at or above its Coupon Barrier on every Eligible Trading Day during an Observation Period, you will not receive a

Principal at Risk Securities Linked to the Lowest Performing of the S&P 500^® Index, the Russell 2000^® Index and the Nasdaq-100^® Index due April 29, 2027

Contingent Coupon Payment with respect to the related Observation Period if the closing level of another Underlying is below its Coupon Barrier on any Eligible Trading Day during that Observation Period. In addition, even if the Ending Value of an Underlying is at or above its Threshold Value, you will lose a portion of your principal if the Ending Value of the Lowest Performing Underlying is below its Threshold Value.

Higher Contingent Coupon Rates are associated with greater risk. The Securities offer Contingent Coupon Payments at a higher rate, if paid, than the fixed rate we would pay on conventional debt securities of the same maturity. These higher potential Contingent Coupon Payments are associated with greater levels of expected risk as of the Pricing Date as compared to conventional debt securities, including the risk that you may not receive a Contingent Coupon Payment on one or more, or any, Contingent Coupon Payment Dates and the risk that you may lose a substantial portion, and possibly all, of the principal amount per Security at maturity. The volatility of the Underlyings and the correlation among the Underlyings are important factors affecting this risk. Volatility is a measurement of the size and frequency of daily fluctuations in the level of an Underlying, typically observed over a specified period of time. Volatility can be measured in a variety of ways, including on a historical basis or on an expected basis as implied by option prices in the market. Correlation is a measurement of the extent to which the levels of the Underlyings tend to fluctuate at the same time, in the same direction and in similar magnitudes. Greater expected volatility of the Underlyings or lower expected correlation among the Underlyings as of the Pricing Date may result in a higher Contingent Coupon Rate, but it also represents a greater expected likelihood as of the Pricing Date that the closing level of at least one Underlying will be less than its Coupon Barrier on one or more Eligible Trading Days during one or more Observation Periods, such that you will not receive one or more, or any, Contingent Coupon Payments during the term of the Securities, and that the closing level of at least one Underlying will be less than its Threshold Value on the Final Calculation Day such that you will lose a substantial portion, and possibly all, of the principal amount per Security at maturity. In general, the higher the Contingent Coupon Rate is relative to the fixed rate we would pay on conventional debt securities, the greater the expected risk that you will not receive one or more, or any, Contingent Coupon Payments during the term of the Securities and that you will lose a substantial portion, and possibly all, of the principal amount per Security at maturity.

Your return on the Securities may be less than the yield on a conventional debt security of comparable maturity. Any return that you receive on the Securities may be less than the return you would earn if you purchased a conventional debt security with the same Maturity Date. As a result, your investment in the Securities may not reflect the full opportunity cost to you when you consider factors, such as inflation, that affect the time value of money. In addition, if interest rates increase during the term of the Securities, the Contingent Coupon Payment (if any) may be less than the yield on a conventional debt security of comparable maturity.

A Contingent Coupon Payment Date, an Optional Redemption Date and the Maturity Date may be postponed if an Observation Period End-Date is postponed. An Observation Period End-Date (including the Final Calculation Day) with respect to an Underlying will be postponed if the applicable originally scheduled Observation Period End-Date is not a trading day with respect to any Underlying or if the calculation agent determines that a Market Disruption Event has occurred or is continuing with respect to that Underlying on that Observation Period End-Date. If such a postponement occurs with respect to an Observation Period End-Date other than the Final Calculation Day, then the related Contingent Coupon Payment Date, will be postponed. If such a postponement occurs with respect to the Final Calculation Day, the Maturity Date will be the later of (i) the initial Maturity Date and (ii) three business days after the last Final Calculation Day as postponed.

Any payment on the Securities is subject to our credit risk and the credit risk of the Guarantor, and actual or perceived changes in our or the Guarantor's creditworthiness are expected to affect the value of the Securities. The Securities are our senior unsecured debt securities. Any payment on the Securities will be fully and unconditionally guaranteed by the Guarantor. The Securities are not guaranteed by any entity other than the Guarantor. As a result, your receipt of any Contingent Coupon Payments or the payment upon an early redemption or the Maturity Payment Amount at maturity, as applicable, will be dependent upon our ability and the ability of the Guarantor to repay our respective obligations under the Securities on the applicable payment date, regardless of the closing level of the Lowest Performing Underlying as compared to its Starting Value. No assurance can be given as to what our financial condition or the financial condition of the Guarantor will be at any time after the Pricing Date of the Securities. If we and the Guarantor become unable to meet our respective financial obligations as they become due, you may not receive the amount(s) payable under the terms of the Securities.

In addition, our credit ratings and the credit ratings of the Guarantor are assessments by ratings agencies of our respective abilities to pay our obligations. Consequently, our or the Guarantor's perceived creditworthiness and actual or anticipated decreases in our or the Guarantor's credit ratings or increases in the spread between the yield on our respective securities and the yield on U.S. Treasury securities (the "credit spread") prior to the Maturity Date of your Securities may adversely affect the market value of the Securities. However, because your return on the Securities depends upon factors in addition to our ability and the ability of the Guarantor to pay our respective obligations, such as the levels of the Underlyings, an improvement in our or the Guarantor's credit ratings will not reduce the other investment risks related to the Securities.

We are a finance subsidiary and, as such, have no independent assets, operations or revenues. We are a finance subsidiary of the Guarantor, have no operations other than those related to the issuance, administration and repayment of our debt securities that are guaranteed by the Guarantor, and are dependent upon the Guarantor and/or its other subsidiaries to meet our obligations under the Securities in the ordinary course. Therefore, our ability to make payments on the Securities may be limited.

Valuation- and Market-related Risks

The public offering price you are paying for the Securities exceeds their initial estimated value. The initial estimated value of the Securities that is provided on the cover page of this pricing supplement is an estimate only, determined as of the Pricing Date by

Principal at Risk Securities Linked to the Lowest Performing of the S&P 500^® Index, the Russell 2000^® Index and the Nasdaq-100^® Index due April 29, 2027

reference to our and our affiliates' pricing models. These pricing models consider certain assumptions and variables, including our credit spreads and those of the Guarantor, the Guarantor's internal funding rate, mid-market terms on hedging transactions, expectations on interest rates, dividends and volatility, price-sensitivity analysis, and the expected term of the Securities. These pricing models rely in part on certain forecasts about future events, which may prove to be incorrect. If you attempt to sell the Securities prior to maturity, their market value may be lower than the price you paid for them and lower than their initial estimated value. This is due to, among other things, changes in the levels of the Underlyings, changes in the Guarantor's internal funding rate, and the inclusion in the public offering price of the underwriting discount and the hedging related charges, all as further described in "Structuring the Securities" below. These factors, together with various credit, market and economic factors over the term of the Securities, are expected to reduce the price at which you may be able to sell the Securities in any secondary market and will affect the value of the Securities in complex and unpredictable ways.

The initial estimated value does not represent a minimum or maximum price at which we, BAC, BofAS or any of our other affiliates or WFS or its affiliates would be willing to purchase your Securities in any secondary market (if any exists) at any time. The value of your Securities at any time after issuance will vary based on many factors that cannot be predicted with accuracy, including the performance of the Underlyings, our and BAC's creditworthiness and changes in market conditions.

We cannot assure you that a trading market for your Securities will ever develop or be maintained. We will not list the Securities on any securities exchange. We cannot predict how the Securities will trade in any secondary market or whether that market will be liquid or illiquid.

The Securities are not designed to be short-term trading instruments, and if you attempt to sell the Securities prior to maturity, their market value, if any, will be affected by various factors that interrelate in complex ways, and their market value may be less than the principal amount. The following factors are expected to affect the value of the Securities: value of the Underlyings at such time; volatility of the Underlyings; economic and other conditions generally; interest rates; dividend yields; exchange rate movements and volatility; our and the Guarantor's financial condition and creditworthiness; and time to maturity.

Conflict-related Risks

Trading and hedging activities by us, the Guarantor and any of our other affiliates, including BofAS, and WFS and its affiliates, may create conflicts of interest with you and may affect your return on the Securities and their market value. We, the Guarantor or one or more of our other affiliates, including BofAS, and WFS and its affiliates, may buy or sell the securities held by or included in the Underlyings, or futures or options contracts on the Underlyings or those securities, or other listed or over-the-counter derivative instruments linked to the Underlyings or those securities. While we, the Guarantor or one or more of our other affiliates, including BofAS, and WFS and its affiliates, may from time to time own securities represented by the Underlyings, except to the extent that BAC's or Wells Fargo & Company's (the parent company of WFS) common stock may be included in the Underlyings, as applicable, we, the Guarantor and our other affiliates, including BofAS, and WFS and its affiliates, do not control any company included in the Underlyings, and have not verified any disclosure made by any other company. We, the Guarantor or one or more of our other affiliates, including BofAS, or WFS and its affiliates, may execute such purchases or sales for our own or their own accounts, for business reasons, or in connection with hedging our obligations under the Securities. These transactions may present a conflict of interest between your interest in the Securities and the interests we, the Guarantor and our other affiliates, including BofAS, and WFS and its affiliates, may have in our or their proprietary accounts, in facilitating transactions, including block trades, for our or their other customers, and in accounts under our or their management. These transactions may adversely affect the levels of the Underlyings in a manner that could be adverse to your investment in the Securities. On or before the Pricing Date, any purchases or sales by us, the Guarantor or our other affiliates, including BofAS or others on its behalf, and WFS and its affiliates (including for the purpose of hedging some or all of our anticipated exposure in connection with the Securities), may have affected the levels of the Underlyings. Consequently, the levels of the Underlyings may change subsequent to the Pricing Date, which may adversely affect the market value of the Securities.

We, the Guarantor or one or more of our other affiliates, including BofAS, and WFS and its affiliates, also may have engaged in hedging activities that could have affected the levels of the Underlyings on the Pricing Date. In addition, these hedging activities, including the unwinding of a hedge, may decrease the market value of your Securities prior to maturity, and may affect the amounts to be paid on the Securities. We, the Guarantor or one or more of our other affiliates, including BofAS, and WFS and its affiliates, may purchase or otherwise acquire a long or short position in the Securities and may hold or resell the Securities. For example, BofAS may enter into these transactions in connection with any market making activities in which it engages. We cannot assure you that these activities will not adversely affect the levels of the Underlyings, the market value of your Securities prior to maturity or the amounts payable on the Securities.

If WFS, BofAS or an affiliate of either selling agent participating as a dealer in the distribution of the Securities conducts hedging activities for us in connection with the Securities, such selling agent or participating dealer will expect to realize a projected profit from such hedging activities, and this projected profit will be in addition to any discount, concession or fee received in connection with the sale of the Securities to you. This additional projected profit may create a further incentive for the selling agents or participating dealers to sell the Securities to you.

There may be potential conflicts of interest involving the calculation agent, which is an affiliate of ours. We have the right to appoint and remove the calculation agent. One of our affiliates will be the calculation agent for the Securities and, as such, will make a variety of determinations relating to the Securities, including the amounts that will be paid on the Securities. Under some

circumstances, these duties could result in a conflict of interest between its status as our affiliate and its responsibilities as calculation agent.

Underlying-related Risks

Any payments on the Securities will depend upon the performance of the Underlyings, and therefore the Securities are subject to the following risks, each as discussed in more detail in the accompanying product supplement.

The Securities are subject to risks associated with foreign securities markets. The NDX includes certain foreign equity securities. You should be aware that investments in securities linked to the value of foreign equity securities involve particular risks. The foreign securities markets comprising the NDX may have less liquidity and may be more volatile than U.S. or other securities markets and market developments may affect foreign markets differently from U.S. or other securities markets. Direct or indirect government intervention to stabilize these foreign securities markets, as well as cross-shareholdings in foreign companies, may affect trading prices and volumes in these markets. Also, there is generally less publicly available information about foreign companies than about those U.S. companies that are subject to the reporting requirements of the SEC, and foreign companies are subject to accounting, auditing and financial reporting standards and requirements that differ from those applicable to U.S. reporting companies. Prices of securities in foreign countries are subject to political, economic, financial and social factors that apply in those geographical regions. These factors, which could negatively affect those securities markets, include the possibility of recent or future changes in a foreign government's economic and fiscal policies, the possible imposition of, or changes in, currency exchange laws or other laws or restrictions applicable to foreign companies or investments in foreign equity securities and the possibility of fluctuations in the rate of exchange between currencies, the possibility of outbreaks of hostility and political instability and the possibility of natural disaster or adverse public health developments in the region. Moreover, foreign economies may differ favorably or unfavorably from the U.S. economy in important respects such as growth of gross national product, rate of inflation, capital reinvestment, resources and self-sufficiency.

The Securities are subject to risks associated with small-size capitalization companies. The stocks comprising the RTY are issued by companies with small-sized market capitalization. The stock prices of small-size companies may be more volatile than stock prices of large capitalization companies. Small-size capitalization companies may be less able to withstand adverse economic, market, trade and competitive conditions relative to larger companies. Small-size capitalization companies may also be more susceptible to adverse developments related to their products or services.

Tax-related Risks

The U.S. federal income tax consequences of the Securities are uncertain, and may be adverse to a holder of the Securities. See "U.S. Federal Income Tax Summary" below and "U.S. Federal Income Tax Summary" beginning on page PS-36 of the accompanying product supplement.

If we redeem the Securities prior to the Maturity Date:

If we redeem the Securities prior to the Maturity Date, you will receive the principal amount of your Securities plus, if otherwise due, any Contingent Coupon Payment on the applicable Optional Redemption Date. In the event we redeem the Securities prior to the Maturity Date, your total return on the Securities will equal any Contingent Coupon Payments received prior to the Optional Redemption Date and any Contingent Coupon Payment received on the Optional Redemption Date.

If we do not redeem the Securities prior to the Maturity Date:

If we do not redeem the Securities prior to the Maturity Date, the following table illustrates, for a range of hypothetical Performance Factors of the Lowest Performing Underlying on the Final Calculation Day, the hypothetical Maturity Payment Amount payable at maturity per Security (excluding the final Contingent Coupon Payment, if any). The Performance Factor of the Lowest Performing Underlying on the Final Calculation Day is its Ending Value expressed as a percentage of its Starting Value (i.e., its Ending Value divided by its Starting Value).

The above figures do not take into account Contingent Coupon Payments, if any, received during the term of the Securities. As evidenced above, in no event will you have a positive rate of return based solely on the Maturity Payment Amount received at maturity; any positive return will be based solely on the Contingent Coupon Payments, if any, received during the term of the Securities.

The above figures are for purposes of illustration only and may have been rounded for ease of analysis. If the Securities are not redeemed at our option prior to the Maturity Date, the actual amount you will receive on the Maturity Date will depend on the actual Ending Value of the Lowest Performing Underlying on the Final Calculation Day. The performance of the better performing Underlyings is not relevant to your return on the Securities.

Set forth below are examples that illustrate how to determine whether a Contingent Coupon Payment will be paid on a Contingent Coupon Payment Date, assuming we have not redeemed the Securities prior to such date. The examples do not reflect any specific Contingent Coupon Payment Date. The following examples reflect the Contingent Coupon Rate of 7.80% per annum and assume the hypothetical Starting Value, Coupon Barrier and lowest closing level during an Observation Period for each Underlying indicated in the examples. The terms used for purposes of these hypothetical examples do not represent any actual Starting Value or Coupon Barrier. The hypothetical Starting Value of 100.00 for each Underlying has been chosen for illustrative purposes only and does not represent the actual Starting Value for any Underlying. The actual Starting Value and Coupon Barrier for each Underlying are set forth under "Terms of the Securities" above. For historical data regarding the actual closing levels of the Underlyings, see the historical information provided herein. These examples are for purposes of illustration only and the values used in the examples may have been rounded for ease of analysis. If we were to redeem the Securities on the relevant Coupon Payment Date in either of the examples below, you would receive the principal amount on the Coupon Payment Date in addition to a final Contingent Coupon Payment, if otherwise payable.

Example 1. The closing level of the Lowest Performing Underlying on each Eligible Trading Day during the related Observation Period is greater than or equal to its Coupon Barrier. As a result, investors receive a Contingent Coupon Payment on the applicable Contingent Coupon Payment Date.

Step 1: Determine whether the closing level of the Lowest Performing Underlying on any Eligible Trading Day during the related Observation Period was less than its Coupon Barrier.

In this example, the closing level of each Underlying on each Eligible Trading Day during the related Observation Period is greater than its respective Coupon Barrier.

Step 2: Determine whether a Contingent Coupon Payment will be paid on the applicable Contingent Coupon Payment Date.

Since the hypothetical closing level of the Lowest Performing Underlying on each Eligible Trading Day during the relevant Observation Period is greater than or equal to its Coupon Barrier, you would receive a Contingent Coupon Payment on the applicable Contingent Coupon Payment Date. The Contingent Coupon Payment would be equal to $19.50 per Security, determined as follows: (i) $1,000 multiplied by 7.80% per annum divided by (ii) 4, rounded to the nearest cent.

Example 2. The closing level of the Lowest Performing Underlying on at least one Eligible Trading Day during the related Observation Period is less than its Coupon Barrier. As a result, investors do not receive a Contingent Coupon Payment on the applicable Contingent Coupon Payment Date.

Step 1: Determine whether the closing level of the Lowest Performing Underlying on any Eligible Trading Day during the relevant Observation Period was less than its Coupon Barrier.

In this example, the closing level of the S&P 500^® Index on at least one Eligible Trading Day during the related Observation Period was less than its Coupon Barrier.

Step 2: Determine whether a Contingent Coupon Payment will be paid on the applicable Contingent Coupon Payment Date.

Since the hypothetical closing level of at least one Underlying on at least one Eligible Trading Day during the relevant Observation Period is less than its Coupon Barrier, you would not receive a Contingent Coupon Payment on the applicable Contingent Coupon Payment Date. This is the case even though the closing levels of the better performing Underlyings were greater than their

respective Coupon Barriers on every Eligible Trading Day during the relevant Observation Period, and would be the case even if the closing level of the S&P 500^® Index was greater than or equal to its Coupon Barrier on every other Eligible Trading Day during the relevant Observation Period.

As this example illustrates, whether you receive a Contingent Coupon Payment on a Coupon Payment Date will depend solely on the closing level of the Lowest Performing Underlying on each Eligible Trading Day during the relevant Observation Period. Therefore, if the closing level of any one of the Underlyings is less than its Coupon Barrier on any Eligible Trading Day during an Observation Period, you will not receive a Contingent Coupon Payment with respect to that Observation Period. This will be the case even if the closing level of that Underlying is greater than or equal to its Coupon Barrier on every other Eligible Trading Day during that Observation Period, and even if the better performing indices perform favorably. The performance of the better performing Underlyings is not relevant to your return on the Securities.

Set forth below are examples of calculations of the Maturity Payment Amount payable on the Maturity Date, assuming that we have not redeemed the Securities prior to the Maturity Date and assuming the hypothetical Starting Value, Coupon Barrier, Threshold Value and Ending Value for each Underlying indicated in the examples. The terms used for purposes of these hypothetical examples do not represent any actual Starting Value, Coupon Barrier or Threshold Value. The hypothetical Starting Value of 100.00 for each Underlying has been chosen for illustrative purposes only and does not represent the actual Starting Value for any Underlying. The actual Starting Value, Coupon Barrier and Threshold Value for each Underlying are set forth under "Terms of the Securities" above. For historical data regarding the actual closing levels of the Underlyings, see the historical information provided herein. These examples are for purposes of illustration only and the values used in the examples may have been rounded for ease of analysis.

Example 1. The closing level of the Lowest Performing Underlying on each Eligible Trading Day during the final Observation Period is greater than or equal to its Coupon Barrier, and the Ending Value of the Lowest Performing Underlying on the Final Calculation Day is greater than its Starting Value. As a result, the Maturity Payment Amount is equal to the principal amount of your Securities at maturity and you receive a final Contingent Coupon Payment:

Step 1: Determine which Underlying is the Lowest Performing Underlying on the Final Calculation Day.

In this example, the Nasdaq-100^® Index has the lowest Performance Factor on the Final Calculation Day and is, therefore, the Lowest Performing Underlying on the Final Calculation Day.

Step 2: Determine the Maturity Payment Amount based on the Ending Value of the Lowest Performing Underlying on the Final Calculation Day.

Since the hypothetical Ending Value of the Lowest Performing Underlying on the Final Calculation Day is greater than or equal to its hypothetical Threshold Value, the Maturity Payment Amount would equal the principal amount. Although the hypothetical Ending Value of the Lowest Performing Underlying on the Final Calculation Day is significantly greater than its hypothetical Starting Value in this scenario, the Maturity Payment Amount will not exceed the principal amount.

In addition to any Contingent Coupon Payments received during the term of the Securities, on the Maturity Date you would receive $1,000.00 per Security as well as a final Contingent Coupon Payment because the hypothetical closing level of the Lowest Performing Underlying on each Eligible Trading Day during the final Observation Period was greater than or equal to its hypothetical Coupon Barrier.

Example 2. The closing level of the Lowest Performing Underlying on at least one Eligible Trading Day during the final Observation Period is less than its Coupon Barrier, and the Ending Value of the Lowest Performing Underlying on the Final Calculation Day is less than its Starting Value but greater than its Threshold Value. As a result, the Maturity Payment Amount is equal to the principal amount of your Securities at maturity, but you do not receive a final Contingent Coupon Payment:

Step 1: Determine which Underlying is the Lowest Performing Underlying on the Final Calculation Day.

In this example, the S&P 500^® Index has the lowest Performance Factor on the Final Calculation Day and is, therefore, the Lowest Performing Underlying on the Final Calculation Day.

Step 2: Determine the Maturity Payment Amount based on the Ending Value of the Lowest Performing Underlying on the Final Calculation Day.

Since the hypothetical Ending Value of the Lowest Performing Underlying on the Final Calculation Day is greater than or equal to its hypothetical Threshold Value, you would receive the principal amount of your Securities at maturity.

In addition to any Contingent Coupon Payments received during the term of the Securities, on the Maturity Date you would receive $1,000.00 per Security, but no final Contingent Coupon Payment since the hypothetical closing level of the Lowest Performing Underlying on at least one Eligible Trading Day during the final Observation Period was less than its Coupon Barrier. This is the case even though the closing levels of the better performing Underlyings were greater than their respective Coupon Barriers on every Eligible Trading Day during the relevant Observation Period, and even though the Ending Value of the S&P 500^® Index was greater than its Coupon Barrier.

Example 3. The Ending Value of the Lowest Performing Underlying on the Final Calculation Day is less than its Threshold Value and its Coupon Barrier, the Maturity Payment Amount is less than the principal amount of your Securities at maturity and you do not receive a final Contingent Coupon Payment:

Step 1: Determine which Underlying is the Lowest Performing Underlying on the Final Calculation Day.

In this example, the Russell 2000^® Index has the lowest Performance Factor on the Final Calculation Day and is, therefore, the Lowest Performing Underlying on the Final Calculation Day.

Step 2: Determine the Maturity Payment Amount based on the Ending Value of the Lowest Performing Underlying on the Final Calculation Day.

Since the hypothetical Ending Value of the Lowest Performing Underlying on the Final Calculation Day is less than its hypothetical Threshold Value, you would lose a portion of the principal amount of your Securities and receive the Maturity Payment Amount equal to $450.00 per Security, calculated as follows:

= $1,000 × Performance Factor of the Lowest Performing Underlying on the Final Calculation Day

= $1,000 × 45.00%

= $450.00

In addition to any Contingent Coupon Payments received during the term of the Securities, on the Maturity Date you would receive $450.00 per Security, but no final Contingent Coupon Payment since the hypothetical closing level of the Lowest Performing Underlying on at least one Eligible Trading Day during the final Observation Period was less than its Coupon Barrier.

These examples illustrate that you will not participate in any appreciation of any Underlying, but will be fully exposed to a decrease in the Lowest Performing Underlying if the Ending Value of the Lowest Performing Underlying on the Final Calculation Day is less than its Threshold Value, even if the Ending Values of the other Underlyings have appreciated or have not declined below their respective Threshold Values.

To the extent that the Starting Value, Coupon Barrier, Threshold Value and Ending Value of the Lowest Performing Underlying on each Eligible Trading Day during an Observation Period and on the Final Calculation Day, as applicable, differ from the values assumed above, the results indicated above would be different.

The SPX includes a representative sample of 500 companies in leading industries of the U.S. economy. The SPX is intended to provide an indication of the pattern of common stock price movement. The calculation of the level of the SPX is based on the relative value of the aggregate market value of the common stocks of 500 companies as of a particular time compared to the aggregate average market value of the common stocks of 500 similar companies during the base period of the years 1941 through 1943.

The SPX includes companies from eleven main groups: Communication Services; Consumer Discretionary; Consumer Staples; Energy; Financials; Health Care; Industrials; Information Technology; Real Estate; Materials; and Utilities. SPDJI may from time to time, in its sole discretion, add companies to, or delete companies from, the SPX to achieve the objectives stated above.

Company additions to the SPX must have an unadjusted company market capitalization of $18.0 billion or more (an increase from the previous requirement of an unadjusted company market capitalization of $15.8 billion or more).

SPDJI calculates the SPX by reference to the prices of the constituent stocks of the SPX without taking account of the value of dividends paid on those stocks. As a result, the return on the Securities will not reflect the return you would realize if you actually owned the SPX constituent stocks and received the dividends paid on those stocks.

Computation of the SPX

While SPDJI currently employs the following methodology to calculate the SPX, no assurance can be given that SPDJI will not modify or change this methodology in a manner that may affect payments on the Securities.

Historically, the market value of any component stock of the SPX was calculated as the product of the market price per share and the number of then outstanding shares of such component stock. In March 2005, SPDJI began shifting the SPX halfway from a market capitalization weighted formula to a float-adjusted formula, before moving the SPX to full float adjustment on September 16, 2005. SPDJI's criteria for selecting stocks for the SPX did not change with the shift to float adjustment. However, the adjustment affects each company's weight in the SPX.

Under float adjustment, the share counts used in calculating the SPX reflect only those shares that are available to investors, not all of a company's outstanding shares. Float adjustment excludes shares that are closely held by control groups, other publicly traded companies or government agencies.

In September 2012, all shareholdings representing more than 5% of a stock's outstanding shares, other than holdings by "block owners," were removed from the float for purposes of calculating the SPX. Generally, these "control holders" will include officers and directors, private equity, venture capital and special equity firms, other publicly traded companies that hold shares for control, strategic partners, holders of restricted shares, ESOPs, employee and family trusts, foundations associated with the company, holders of unlisted share classes of stock, government entities at all levels (other than government retirement/pension funds) and any individual person who controls a 5% or greater stake in a company as reported in regulatory filings. However, holdings by block owners, such as depositary banks, pension funds, mutual funds and ETF providers, 401(k) plans of the company, government retirement/pension funds, investment funds of insurance companies, asset managers and investment funds, independent foundations and savings and investment plans, will ordinarily be considered part of the float.

Treasury stock, stock options, restricted shares, equity participation units, warrants, preferred stock, convertible stock, and rights are not part of the float. Shares held in a trust to allow investors in countries outside the country of domicile, such as depositary shares and Canadian exchangeable shares are normally part of the float unless those shares form a control block. If a company has multiple classes of stock outstanding, shares in an unlisted or non-traded class are treated as a control block.

For each stock, an investable weight factor ("IWF") is calculated by dividing the available float shares by the total shares outstanding. Available float shares are defined as the total shares outstanding less shares held by control holders. This calculation is subject to a 5% minimum threshold for control blocks. For example, if a company's officers and directors hold 3% of the company's shares, and no other control group holds 5% of the company's shares, SPDJI would assign that company an IWF of 1.00, as no control group meets the 5% threshold. However, if a company's officers and directors hold 3% of the company's shares and another control group holds 20% of the company's shares, SPDJI would assign an IWF of 0.77, reflecting the fact that 23% of the company's outstanding shares are considered to be held for control. As of July 31, 2017, companies with multiple share class lines are no longer eligible for inclusion in the SPX.

Constituents of the SPX prior to July 31, 2017 with multiple share class lines will be grandfathered in and continue to be included in the SPX. If a constituent company of the SPX reorganizes into a multiple share class line structure, that company will remain in the SPX at the discretion of the S&P Index Committee in order to minimize turnover.

The SPX is calculated using a base-weighted aggregate methodology. The level of the SPX reflects the total market value of all component stocks relative to the base period of the years 1941 through 1943. An indexed number is used to represent the results of this calculation in order to make the level easier to work with and track over time. The actual total market value of the component stocks during the base period of the years 1941 through 1943 has been set to an indexed level of 10. This is often indicated by the notation 1941- 43 = 10. In practice, the daily calculation of the SPX is computed by dividing the total market value of the component stocks by the "index divisor." By itself, the index divisor is an arbitrary number. However, in the context of the calculation of the SPX, it serves as a link to the original base period level of the SPX. The index divisor keeps the SPX comparable over time and is the manipulation point for all adjustments to the SPX, which is index maintenance.

Index Maintenance

Index maintenance includes monitoring and completing the adjustments for company additions and deletions, share changes, stock splits, stock dividends, and stock price adjustments due to company restructuring or spinoffs. Some corporate actions, such as stock splits and stock dividends, require changes in the common shares outstanding and the stock prices of the companies in the SPX, and do not require index divisor adjustments.

To prevent the level of the SPX from changing due to corporate actions, corporate actions which affect the total market value of the SPX require an index divisor adjustment. By adjusting the index divisor for the change in market value, the level of the SPX remains constant and does not reflect the corporate actions of individual companies in the SPX. Index divisor adjustments are made after the close of trading and after the calculation of the SPX closing level.

Changes in a company's shares outstanding of 5.00% or more due to mergers, acquisitions, public offerings, tender offers, Dutch auctions, or exchange offers are made as soon as reasonably possible. Share changes due to mergers or acquisitions of publicly held companies that trade on a major exchange are implemented when the transaction occurs, even if both of the companies are not in the same headline index, and regardless of the size of the change. All other changes of 5.00% or more (due to, for example, company stock repurchases, private placements, redemptions, exercise of options, warrants, conversion of preferred stock, notes, debt, equity participation units, at-the-market offerings, or other recapitalizations) are made weekly and are announced on Fridays for implementation after the close of trading on the following Friday. Changes of less than 5.00% are accumulated and made quarterly on the third Friday of March, June, September, and December, and are usually announced two to five days prior.

If a change in a company's shares outstanding of 5.00% or more causes a company's IWF to change by five percentage points or more, the IWF is updated at the same time as the share change. IWF changes resulting from partial tender offers are considered on a case by case basis.

The RTY was developed by Russell Investments ("Russell") before FTSE International Limited and Russell combined in 2015 to create FTSE Russell, which is wholly owned by London Stock Exchange Group. Additional information on the RTY is available at the following website: http://www.ftserussell.com. No information on that website is deemed to be included or incorporated by reference in this pricing supplement.

Russell began dissemination of the RTY on January 1, 1984. FTSE Russell calculates and publishes the RTY. The RTY was set to 135 as of the close of business on December 31, 1986. The RTY is designed to track the performance of the small capitalization segment of the U.S. equity market. As a subset of the Russell 3000^® Index, the RTY consists of the smallest 2,000 companies included in the Russell 3000^® Index. The Russell 3000^® Index measures the performance of the largest 3,000 U.S. companies, representing approximately 98% of the investable U.S. equity market. The RTY is determined, comprised, and calculated by FTSE Russell without regard to the Securities.

Selection of Stocks Comprising the RTY

All companies eligible for inclusion in the RTY must be classified as a U.S. company under FTSE Russell's country-assignment methodology. If a company is incorporated, has a stated headquarters location, and trades in the same country (American Depositary Receipts and American Depositary Shares are not eligible), then the company is assigned to its country of incorporation. If any of the three factors are not the same, FTSE Russell defines three Home Country Indicators ("HCIs"): country of incorporation, country of headquarters, and country of the most liquid exchange (as defined by a two-year average daily dollar trading volume) from all exchanges within a country. Using the HCIs, FTSE Russell compares the primary location of the company's assets with the three HCIs. If the primary location of its assets matches any of the HCIs, then the company is assigned to the primary location of its assets. If there is insufficient information to determine the country in which the company's assets are primarily located, FTSE Russell will use the country from which the company's revenues are primarily derived for the comparison with the three HCIs in a similar manner. FTSE Russell uses the average of two years of assets or revenues data to reduce potential turnover. If conclusive country details cannot be derived from assets or revenues data, FTSE Russell will assign the company to the country of its headquarters, which is defined as the address of the company's principal executive offices, unless that country is a Benefit Driven Incorporation ("BDI") country, in which case the company will be assigned to the country of its most liquid stock exchange. BDI countries include: Anguilla, Antigua and Barbuda, Bahamas, Barbados, Belize, Bermuda, Bonaire, British Virgin Islands, Cayman Islands, Channel Islands, Cook Islands, Curacao, Faroe Islands, Gibraltar, Guernsey, Isle of Man, Jersey, Liberia, Marshall Islands, Panama, Saba, Sint Eustatius, Sint Maarten, and Turks and Caicos Islands. For any companies incorporated or headquartered in a U.S. territory, including Puerto Rico, Guam, and U.S. Virgin Islands, a U.S. HCI is assigned.

All securities eligible for inclusion in the RTY must trade on a major U.S. exchange. Stocks must have a closing price at or above $1.00 on their primary exchange on the last trading day in May to be eligible for inclusion during annual reconstitution. However, in order to reduce unnecessary turnover, if an existing member's closing price is less than $1.00 on the last day of May, it will be considered eligible if the average of the daily closing prices (from its primary exchange) during the month of May is equal to or greater than $1.00. Initial public offerings are added each quarter and must have a closing price at or above $1.00 on the last day of their eligibility period in order to qualify for index inclusion. If an existing stock does not trade on the "rank day" (typically the last trading day in May but a confirmed timetable is announced each spring) but does have a closing price at or above $1.00 on another eligible U.S. exchange, that stock will be eligible for inclusion.

An important criterion used to determine the list of securities eligible for the RTY is total market capitalization, which is defined as the market price as of the last trading day in May for those securities being considered at annual reconstitution times the total number of shares outstanding. Where applicable, common stock, non-restricted exchangeable shares and partnership units/membership interests are used to determine market capitalization. Any other form of shares such as preferred stock, convertible preferred stock, redeemable shares, participating preferred stock, warrants and rights, installment receipts or trust receipts, are excluded from the calculation. If multiple share classes of common stock exist, they are combined. In cases where the common stock share classes act independently of each other (e.g., tracking stocks), each class is considered for inclusion separately. If multiple share classes exist, the pricing vehicle will be designated as the share class with the highest two-year trading volume as of the rank day in May.

Companies with a total market capitalization of less than $30 million are not eligible for the RTY. Similarly, companies with only 5% or less of their shares available in the marketplace are not eligible for the RTY. Royalty trusts, limited liability companies, closed-end investment companies (companies that are required to report Acquired Fund Fees and Expenses, as defined by the SEC, including business development companies), blank check companies, special purpose acquisition companies, and limited partnerships are also ineligible for inclusion. Bulletin board, pink sheets, and over-the-counter traded securities are not eligible for inclusion. Exchange traded funds and mutual funds are also excluded.

Annual reconstitution is a process by which the RTY is completely rebuilt. Based on closing levels of the company's common stock on its primary exchange on the rank day of May of each year, FTSE Russell reconstitutes the composition of the RTY using the then existing market capitalizations of eligible companies. Reconstitution of the RTY occurs on the last Friday in June or, when the last Friday in June is the 29th or 30th, reconstitution occurs on the prior Friday. In addition, FTSE Russell adds initial public offerings to the RTY on a quarterly basis based on total market capitalization ranking within the market-adjusted capitalization breaks established during the most

recent reconstitution. After membership is determined, a security's shares are adjusted to include only those shares available to the public. This is often referred to as "free float." The purpose of the adjustment is to exclude from market calculations the capitalization that is not available for purchase and is not part of the investable opportunity set.

Market Linked Securities-Callable with Contingent Coupon with Daily Observation and Contingent Downside

Principal at Risk Securities Linked to the Lowest Performing of the S&P 500^® Index, the Russell 2000^® Index and the Nasdaq-100^® Index due April 29, 2027

The NDX is intended to measure the performance of the 100 largest domestic and international non-financial securities listed on The Nasdaq Stock Market ("NASDAQ") based on market capitalization. The NDX reflects companies across major industry groups including computer hardware and software, telecommunications, retail/wholesale trade and biotechnology. It does not contain securities of financial companies including investment companies.

The NDX began trading on January 31, 1985 at a base value of 125.00. The NDX is calculated and published by Nasdaq, Inc. In administering the NDX, Nasdaq, Inc. will exercise reasonable discretion as it deems appropriate.

Underlying Stock Eligibility Criteria

NDX eligibility is limited to specific security types only. The security types eligible for the NDX include foreign or domestic common stocks, ordinary shares, ADRs and tracking stocks. Security types not included in the NDX are closed-end funds, convertible debt securities, exchange traded funds, limited liability companies, limited partnership interests, preferred stocks, rights, shares or units of beneficial interest, warrants, units, and other derivative securities. The NDX does not contain securities of investment companies. For purposes of the NDX eligibility criteria, if the security is a depositary receipt representing a security of a non-U.S. issuer, then references to the "issuer" are references to the issuer of the underlying security.

Initial Eligibility Criteria

To be eligible for initial inclusion in the NDX, a security must be listed on NASDAQ and meet the following criteria:

Continued Eligibility Criteria

In addition, to be eligible for continued inclusion in the NDX, the following criteria apply:

Computation of the NDX

The value of the NDX equals the aggregate value of the NDX share weights (the "NDX Shares") of each of the NDX securities multiplied by each such security's last sale price (last sale price refers to the last sale price on NASDAQ), and divided by the divisor of the NDX. If trading in an NDX security is halted while the market is open, the last traded price for that security is used for all NDX computations until trading resumes. If trading is halted before the market is open, the previous day's last sale price is used. The formula for determining the NDX value is as follows:

The NDX is ordinarily calculated without regard to cash dividends on NDX securities. The NDX is calculated during the trading day and is disseminated once per second from 09:30:01 to 17:16:00 ET. The closing level of the NDX may change up until 17:15:00 ET due to corrections to the last sale price of the NDX securities. The official closing value of the NDX is ordinarily disseminated at 17:16:00 ET.

NDX Maintenance

Changes to NDX Constituents

Changes to the NDX constituents may be made during the annual ranking review. In addition, if at any time during the year other than the annual review, it is determined that an NDX security issuer no longer meets the criteria for continued inclusion in the NDX, or is otherwise determined to have become ineligible for continued inclusion in the NDX, it is replaced with the largest market capitalization issuer not currently in the NDX that meets the applicable eligibility criteria for initial inclusion in the NDX.

Ordinarily, a security will be removed from the NDX at its last sale price. However, if at the time of its removal the NDX security is halted from trading on its primary listing market and an official closing price cannot readily be determined, the NDX security may, in Nasdaq, Inc.'s discretion, be removed at a price of $0.00000001 ("zero price"). This zero price will be applied to the NDX security after the close of the market but prior to the time the official closing value of the NDX is disseminated.

Divisor Adjustments

The divisor is adjusted to ensure that changes in the NDX constituents either by corporate actions (that adjust either the price or shares of an NDX security) or NDX participation outside of trading hours do not affect the value of the NDX. All divisor changes occur after the close of the applicable index security markets.

Quarterly NDX Rebalancing

The NDX will be rebalanced on a quarterly basis if it is determined that (1) the current weight of the single NDX security with the largest market capitalization is greater than 24.0% of the NDX or (2) the collective weight of those securities whose individual current weights are in excess of 4.5% exceeds 48.0% of the NDX. In addition, a "special rebalancing" of the NDX may be conducted at any time if Nasdaq, Inc. determines it necessary to maintain the integrity and continuity of the NDX. If either one or both of the above weight distribution conditions are met upon quarterly review, or Nasdaq, Inc. determines that a special rebalancing is necessary, a weight rebalancing will be performed.

If the first weight distribution condition is met and the current weight of the single NDX security with the largest market capitalization is greater than 24.0%, then the weights of all securities with current weights greater than 1.0% ("large securities") will be scaled down proportionately toward 1.0% until the adjusted weight of the single largest NDX security reaches 20.0%.

If the second weight distribution condition is met and the collective weight of those securities whose individual current weights are in excess of 4.5% (or adjusted weights in accordance with the previous step, if applicable) exceeds 48.0% of the NDX, then the weights of all such large securities in that group will be scaled down proportionately toward 1.0% until their collective weight, so adjusted, is equal to 40.0%.

The aggregate weight reduction among the large securities resulting from either or both of the rebalancing steps above will then be redistributed to those securities with weightings of less than 1.0% ("small securities") in the following manner. In the first iteration, the weight of the largest small security will be scaled upwards by a factor which sets it equal to the average NDX weight of 1.0%. The weights of each of the smaller remaining small securities will be scaled up by the same factor reduced in relation to each security's relative ranking among the small securities such that the smaller the NDX security in the ranking, the less its weight will be scaled upward. This is intended to reduce the market impact of the weight rebalancing on the smallest component securities in the NDX.

In the second iteration of the small security rebalancing, the weight of the second largest small security, already adjusted in the first iteration, will be scaled upwards by a factor which sets it equal to the average NDX weight of 1.0%. The weights of each of the smaller

remaining small securities will be scaled up by this same factor reduced in relation to each security's relative ranking among the small securities such that, once again, the smaller the security in the ranking, the less its weight will be scaled upward. Additional iterations will be performed until the accumulated increase in weight among the small securities equals the aggregate weight reduction among the large securities that resulted from the rebalancing in accordance with the two weight distribution conditions discussed above.

Finally, to complete the rebalancing process, once the final weighting percentages for each NDX security have been set, the NDX Shares will be determined anew based upon the last sale prices and aggregate capitalization of the NDX at the close of trading on the last calendar day in February, May, August and November. Changes to the NDX Shares will be made effective after the close of trading on the third Friday in March, June, September and December, and an adjustment to the divisor is made to ensure continuity of the NDX. Ordinarily, new rebalanced NDX Shares will be determined by applying the above procedures to the current NDX Shares. However, Nasdaq, Inc. may, from time to time, determine rebalanced weights, if necessary, by applying the above procedure to the actual current market capitalization of the NDX components. In such instances, Nasdaq, Inc. would announce the different basis for rebalancing prior to its implementation.

During the quarterly rebalancing, data is cutoff as of the previous month end and no changes are made to the NDX from that cutoff until the quarterly index share change effective date, except in the case of changes due to corporate actions with an ex-date.

Adjustments for Corporate Actions

Changes in the price and/or NDX Shares driven by corporate events such as stock dividends, splits, and certain spin-offs and rights issuances will be adjusted on the ex-date. If the change in total shares outstanding arising from other corporate actions is greater than or equal to 10.0%, the change will be made as soon as practicable. Otherwise, if the change in total shares outstanding is less than 10.0%, then all such changes are accumulated and made effective at one time on a quarterly basis after the close of trading on the third Friday in each of March, June, September, and December. The NDX Shares are derived from the security's total shares outstanding. The NDX Shares are adjusted by the same percentage amount by which the total shares outstanding have changed.

The Securities are our debt securities, the return on which is linked to the performance of the Underlyings. The related guarantee is BAC's obligation. Any payments on the Securities, including payment of the Redemption Amount, depend on the credit risk of BofA Finance and BAC and on the performance of the Underlyings. As is the case for all of our and BAC's respective debt securities, including our market-linked securities, the economic terms of the Securities reflect our and BAC's actual or perceived creditworthiness at the time of pricing. In addition, because market-linked securities result in increased operational, funding and liability management costs to us and BAC, BAC typically borrows the funds under these types of securities at a rate, which we refer to in this pricing supplement as BAC's internal funding rate, that is more favorable to BAC than the rate that it might pay for a conventional fixed or floating rate debt security. This generally relatively lower internal funding rate, which is reflected in the economic terms of the Securities, along with the fees and charges associated with market-linked securities, resulted in the initial estimated value of the Securities on the Pricing Date being less than their public offering price.

The initial estimated value of the Securities as of the Pricing Date is set forth on the cover page of this pricing supplement.

In order to meet our payment obligations on the Securities, at the time we issue the Securities, we may choose to enter into certain hedging arrangements (which may include call options, put options or other derivatives) with BofAS or one of our other affiliates. The terms of these hedging arrangements are determined based upon terms provided by BofAS and its affiliates, and take into account a number of factors, including our and BAC's creditworthiness, interest rate movements, the volatility of the Underlying, the tenor of the Securities and the hedging arrangements. The economic terms of the Securities and their initial estimated value depend in part on the terms of these hedging arrangements.

BofAS has advised us that the hedging arrangements will include hedging related charges, reflecting the costs associated with, and our affiliates' profit earned from, these hedging arrangements. Since hedging entails risk and may be influenced by unpredictable market forces, actual profits or losses from these hedging transactions may be more or less than any expected amounts.

In the opinion of McGuireWoods LLP, as counsel to BofA Finance, as issuer, and BAC, as guarantor, when the trustee has made the appropriate entries or notations on Schedule 1 to the master global note that represents the Securities (the "Master Note") identifying the Securities offered hereby as supplemental obligations thereunder in accordance with the instructions of BofA Finance, and the Securities have been delivered against payment therefor as contemplated in this pricing supplement and the related prospectus, prospectus supplement and product supplement, all in accordance with the provisions of the indenture governing the Securities and the related guarantee, such Securities will be the legal, valid and binding obligations of BofA Finance, and the related guarantee will be the legal, valid and binding obligation of BAC, subject, in each case, to the effects of applicable bankruptcy, insolvency (including laws relating to preferences, fraudulent transfers and equitable subordination), reorganization, moratorium and other similar laws affecting creditors' rights generally, and to general principles of equity. This opinion is given as of the date of this pricing supplement and is limited to the Delaware General Corporation Law and the Delaware Limited Liability Company Act (including the statutory provisions, all applicable provisions of the Delaware Constitution and reported judicial decisions interpreting either of the foregoing) and the laws of the State of New York as in effect on the date hereof. In addition, this opinion is subject to customary assumptions about the trustee's authorization, execution and delivery of the indenture governing the Securities and due authentication of the Master Note, the validity, binding nature and enforceability of the indenture governing the Securities and the related guarantee with respect to the trustee, the legal capacity of individuals, the genuineness of signatures, the authenticity of all documents submitted to McGuireWoods LLP as originals, the conformity to original documents of all documents submitted to McGuireWoods LLP as copies thereof, the authenticity of the originals of such copies and certain factual matters, all as stated in the opinion letter of McGuireWoods LLP dated December 8, 2022, which has been filed as an exhibit to the Registration Statement (File Nos. 333-268718 and 333-268718-01) of BAC and BofA Finance, filed with the SEC on December 8, 2022.
