JNL/PPM America Investment Grade Credit Fund

Class A

Class I

Before you invest, you may want to review the Fund's Prospectus, which contains more information about the Fund and its risks. You can find the Fund's Prospectus and other information about the Fund, including the Statement of Additional Information ("SAI") and most recent reports to shareholders, online at https://www.jackson.com/fund-literature.html. You can also get this information at no cost by calling 1-800-644-4565 (Annuity and Life Service Center), 1-800-599-5651 (NY Annuity and Life Service Center), 1-800-777-7779 (for contracts purchased through a bank or financial institution) or 1-888-464-7779 (for NY contracts purchased through a bank or financial institution), or by sending an email request to [email protected]. The current Prospectus and SAI, both dated April 29, 2024, as amended, are incorporated by reference into (which means they legally are a part of) this Summary Prospectus.

Investment Objective. The Fund seeks to realize maximum total return, consisting of income and capital appreciation.

Expenses. This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund.

The expenses do not reflect the expenses of the variable insurance contracts or the separate account through which you indirectly invest in the Fund, whichever may be applicable, and the total expenses would be higher if they were included.

You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

Expense Example. This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. Also, this example does not reflect the expenses of the variable insurance contracts or the separate account through which you indirectly invest in the Fund, whichever may be applicable, and the total expenses would be higher if they were included. The table below shows the expenses you would pay on a $10,000 investment, assuming (1) 5% annual return; (2) redemption at the end of each time period; and (3) that the Fund operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover (% of average value of portfolio). The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in Annual Fund Operating Expenses or in the Expense Example above, affect the Fund's performance. The Fund does not have a portfolio turnover rate as of the date of this Prospectus as it commenced operations on the date of this Prospectus.

Principal Investment Strategies. The Fund seeks to achieve its objective by investing, under normal circumstances, at least 80% of its assets (net assets plus the amount of any borrowings made for investment purposes) in a diversified portfolio of U.S. dollar-denominated investment grade debt securities of U.S. and foreign issuers (measured at the time of purchase). The debt securities in which the Fund may invest include, but are not limited to, government, corporate, mortgage-backed securities, commercial mortgage-backed securities, asset-backed securities and cash equivalents. Investment grade securities are securities that are rated investment grade (i.e., rated above BBB- or Baa3) by at least one major credit rating agency or, if not rated by any credit rating agency, deemed to be investment-grade quality by PPM America, Inc. (the "Sub-Adviser"). The Sub-Adviser will consider split-rated securities, which are securities that are rated as investment grade by at least one credit rating agency but rated below investment grade by another agency, to be investment grade securities. The Fund will seek to maintain a portfolio duration within one year (plus or minus) of the duration of the Bloomberg U.S. Credit Index. Duration is a measure of a bond price's sensitivity to a change in interest rates (e.g., if interest rates were to rise in a parallel manner by an equal 1%, a bond or bond fund with a five-year average duration would lose approximately 5% of its value). As of December 29, 2023, the ten-year average duration of the Bloomberg U.S. Credit Index was 7.38 years.

The Fund's investments in U.S. dollar-denominated securities of foreign issuers may include securities of issuers based in emerging markets. Emerging market countries are generally considered to be countries with developing economies or markets and may include any country recognized to be an emerging market country by the International Monetary Fund, MSCI, Inc. or Standard & Poor's Corporation or recognized to be a developing country by the United Nations.

For purposes of satisfying the 80% requirement, the Fund may also invest in derivative instruments that have economic characteristics similar to the fixed income instruments mentioned above such as futures contracts, options or swap agreements. Specifically, the Fund may use futures to hedge duration or to increase the Fund's exposure to interest rate or yield curve risk. The Fund may also use credit default swaps or credit default swap indices (CDX) to increase or decrease the Fund's exposure to credit risk or to hedge credit risk in a particular name, industry or sector. The Fund may invest without limitation in derivative instruments. The Fund may, without limitation, seek to obtain market exposure to the securities in which it primarily invests by entering into purchase and sale contracts of mortgage pools or by using other investment techniques (such as dollar rolls).

Additionally, the Fund has the ability to invest in other investment companies, such as money market funds and exchange-traded funds ("ETFs"). For purposes of satisfying the 80% requirement, the Fund may invest in fixed income ETFs comprised of the securities described above. The Fund may also invest in contingent convertible securities, sometimes referred to as "CoCos." CoCos are a form of hybrid debt security issued by banking institutions that are intended to either automatically convert into equity or have their principal written down upon the occurrence of certain pre-specified trigger events.

Principal Risks of Investing in the Fund. An investment in the Fund is not guaranteed. As with any mutual fund, the value of the Fund's shares will change, and you could lose money by investing in the Fund. The principal risks associated with investing in the Fund include:

•

Interest rate risk - When interest rates increase, fixed-income securities generally will decline in value. Long-term fixed income securities normally have more price volatility than short-term fixed income securities. The value of certain equity investments, such as utilities and real estate-related securities, may also be sensitive to interest rate changes.

•

Market risk - Portfolio securities may decline in value due to factors affecting securities markets generally, such as real or perceived adverse economic, political, or regulatory conditions, inflation, changes in interest or currency rates or adverse investor sentiment, public health issues, including widespread disease and virus epidemics or pandemics, war, terrorism or natural disasters, among others. Adverse market conditions may be prolonged and may not have the same impact on all types of securities. The values of securities may fall due to factors affecting a particular issuer, industry or the securities market as a whole.

•

Issuer risk - The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the market as a whole. A security's value may decline for reasons that directly relate to the issuer, such as management performance, corporate governance, financial leverage and reduced demand for the issuer's goods or services.

•

Credit risk - Credit risk is the actual or perceived risk that the issuer of a bond, borrower, guarantor, counterparty, or other entity responsible for payment will not pay interest and principal payments when due. The price of a debt instrument can decline in response to changes in the financial condition of the issuer, borrower, guarantor, counterparty, or other entity responsible for payment. The Fund could lose money if the issuer or guarantor of a fixed-income security, or the counterparty to a derivatives contract, repurchase agreement or a loan of portfolio securities, is unable or unwilling to make timely principal and/or interest payments, or to otherwise honor its obligations.

•

Income risk - The Fund is subject to the risk that the income generated from the Fund's investments may decline in the event of falling interest rates. Income risk may be high if the Fund's income is predominantly based on short-term interest rates, which can fluctuate significantly over short periods. The Fund's distributions to shareholders may decline when interest rates fall.

•

Mortgage-related and other asset-backed securities risk - Rising interest rates tend to extend the duration of mortgage-related and other asset-backed securities, making them more sensitive to changes in interest rates and exhibit increased volatility. When interest rates decline, borrowers may pay off their mortgages or other loans sooner than expected, which can reduce the returns.

•

U.S. Government securities risk - Obligations issued by agencies and instrumentalities of the U.S. Government vary in the level of support they receive from the U.S. Government. They may be: (i) supported by the full faith and credit of the U.S. Treasury; (ii) supported by the right of the issuer to borrow from the U.S. Treasury; (iii) supported by the discretionary authority of the U.S. Government to purchase the issuer's obligations; or (iv) supported only by the credit of the issuer. The maximum potential liability of the issuers of some U.S. Government securities may greatly exceed their current resources, or their legal right to receive support from the U.S. Treasury.

•

Debt securities ratings risk- The use of credit ratings in evaluating debt securities can involve certain risks, including the risk that the credit rating may not reflect the issuer's current financial condition or events since the security was last rated by a rating agency. Credit ratings may be influenced by conflicts of interest or based on historical data that no longer apply or are accurate.

•

Derivatives risk - Investments in derivatives, which are financial instruments whose value depends on, or is derived from, the value of underlying assets, reference rates, or indices, can be highly volatile and may be subject to transaction costs and certain risks, such as unanticipated changes in securities prices and global currency investment. Derivatives also are subject to leverage risk, liquidity risk, interest rate risk, market risk, counterparty risk, and credit risk. They also involve the risk of mispricing or improper valuation and the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, interest rate or index. Gains or losses from derivatives can be substantially greater than the derivatives' original cost.

•

Liquidity risk - Investments in securities that are difficult to purchase or sell (illiquid or thinly-traded securities) may reduce returns if the Fund is unable to sell the securities at an advantageous time or price or achieve its desired level of exposure to a certain sector. Liquidity risk arises, for example, from small average trading volumes, trading restrictions, or temporary suspensions of trading. To meet redemption requests, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

•

Managed portfolio risk - As an actively managed portfolio, the Fund's portfolio manager(s) make decisions to buy and sell holdings in the Fund's portfolio. Because of this, the value of the Fund's investments could decline because the financial condition of an issuer may change (due to such factors as management performance, reduced demand or overall market changes), financial markets may fluctuate or overall prices may decline, the Sub-Adviser's investment techniques could fail to achieve the Fund's investment objective or negatively affect the Fund's investment performance, or legislative, regulatory, or tax developments may affect the investment techniques available to the Sub-Adviser of the Fund. There is no guarantee that the investment objective of the Fund will be achieved.

•

When-issued and delayed delivery securities and forward commitments risk - When-issued, delayed delivery securities and forward commitments transactions arise when securities are purchased by the Fund with payment and delivery taking place in the future in order to secure what is considered to be an advantageous price or yield to the Fund at the time of entering into the transaction. When-issued and delayed delivery securities and forward commitments involve the risk that the security the Fund buys will lose value prior to its delivery. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation. If this occurs, the Fund loses both the investment opportunity for the assets it set aside to pay for the security and any gain in the security's price.

•

Leverage risk - Certain derivative transactions involve the use of leverage and may cause the Fund to liquidate portfolio positions at disadvantageous times to satisfy its obligations. The effect of using leverage is to amplify the Fund's gains and losses in comparison to the amount of the Fund's assets (that is, assets other than borrowed assets) at risk, which may cause the Fund's portfolio to be more volatile. If the Fund uses leverage, the Fund has the risk of capital losses that exceed the net assets of the Fund.

•

Counterparty risk - Transactions involving a counterparty are subject to the credit risk of the counterparty. A fund that enters into contracts with counterparties, such as repurchase or reverse repurchase agreements or derivatives contracts, or that lends its securities, runs the risk that the counterparty will be unable or unwilling to make timely settlement payments or otherwise honor its obligations. If a counterparty fails to meet its contractual obligations, files for bankruptcy, or otherwise experiences a business interruption, the Fund could suffer losses, including monetary losses, miss investment opportunities or be forced to hold investments it would prefer to sell. Counterparty risk is heightened during unusually adverse market conditions.

•

Rule 144A securities risk - Rule 144A securities are securities offered as exempt from registration with the SEC, but may be treated as liquid securities because there is a market for such securities. Rule 144A securities may have an active trading market, but carry the risk that the active trading market may not continue. To the extent that institutional buyers become, for a time, uninterested in purchasing Rule 144A securities, investing in such securities could increase the Fund's level of illiquidity.

•

Contingent convertible securities risk - Contingent convertible securities ("CoCos") are a form of hybrid fixed-income instrument. They are subordinated instruments that are designed to behave like bonds or preferred equity in times of economic health for the issuer, yet absorb losses when a pre-determined "trigger event" affecting the issuer occurs. CoCos are either convertible into equity at a predetermined share price or written down if a pre-specified trigger event occurs (in certain circumstances, the value may be written down to zero). Trigger events vary by individual security and are defined by the documents governing the contingent convertible security. The triggers are generally linked to regulatory capital thresholds or regulatory actions calling into question the issuing banking institution's continued viability as a going-concern. CoCos' unique equity conversion or principal write-down features are tailored to the issuing banking institution and its regulatory requirements. If the CoCos are converted into the issuer's underlying equity securities following a conversion event (i.e., a "trigger"), each holder will be subordinated due to their conversion from being the holder of a debt instrument to being the holder of an equity instrument.

•

Settlement risk - Settlement risk is the risk that a settlement in a transfer system does not take place as expected. Loan transactions often settle on a delayed basis compared with securities and the Fund may not receive proceeds from the sale of a loan for a substantial period after the sale, potentially impacting the ability of the Fund to make additional investments or meet redemption obligations. It may take longer than seven days for transactions in loans to settle. In order to meet short-term liquidity needs, the Fund may draw on its cash or other short-term positions, maintain short-term or other liquid assets sufficient to meet reasonably anticipated redemptions, or maintain a credit facility.

•

Emerging markets and less developed countries risk - Emerging market and less developed countries generally are located in Asia, the Middle East, Eastern Europe, Central and South America and Africa.Investments in, or exposure to, securities that are tied economically to emerging market and less developed countries are subject to all of the risks of investments in, or exposure to, foreign securities, generally to a greater extent than in developed markets, among other risks. Investments in securities that are tied economically to emerging markets involve greater risk from economic and political systems that typically are less developed, and likely to be less stable, than those in more advanced countries. The Fund also will be subject to the risk of adverse foreign currency rate fluctuations. Emerging market and less developed countries may also have economies that are predominantly based on only a few industries or dependent on revenues from particular commodities. The risks of nationalization, expropriation or other confiscation of assets of non-U.S. issuers is also greater in emerging and less developed countries. As a result of these risks, investments in securities tied economically to emerging markets tend to be more volatile than investments in securities of developed countries.

•

Investment in other investment companies risk - As with other investments, investments in other investment companies, including exchange-traded funds, are subject to market risk. In addition, if the Fund acquires shares of investment companies, including ones affiliated with the Fund, shareholders bear both their proportionate share of expenses in the Fund (including management and advisory fees) and, indirectly, the expenses of the investment companies in which the Fund invests. To the extent that shares of the Fund are held by an affiliated fund, the ability of the Fund itself to invest in other investment companies may be limited.

•

Extension risk - When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, which may cause the value of those securities to fall. Rising interest rates tend to extend the duration of securities, making them more sensitive to changes in interest rates. The value of longer-term securities generally changes more in response to changes in interest rates than shorter-term securities. As a result, in a period of rising interest rates, securities may exhibit additional volatility and may lose value.

•

Prepayment risk - During periods of falling interest rates, a debt security with a high interest rate may be prepaid before its expected maturity date. The Fund may have to reinvest the proceeds in an investment that may have lower yields than the yield on the prepaid debt security. In addition, prepayment rates are difficult to predict and the potential impact of prepayment on the price of a debt instrument depends on the terms of the instrument.

•	Call risk - Call risk is the risk that, during a period of falling interest rates, the issuer may redeem a security by repaying it early, which may reduce the Fund's income if the proceeds are reinvested at lower interest rates.

•

Portfolio turnover risk - Frequent changes in the securities held by the Fund, including investments made on a shorter-term basis or in derivative instruments or in instruments with a maturity of one year or less at the time of acquisition, may increase transaction costs, which may reduce performance.

•

Foreign securities risk - Investments in, or exposure to, foreign securities involve risks not typically associated with U.S. investments. These risks include, among others, adverse fluctuations in foreign currency values, possible imposition of foreign withholding or other taxes on income payable on the securities, as well as adverse political, social and economic developments, such as political upheaval, acts of terrorism, financial troubles, sanctions or the threat of new or modified sanctions, or natural disasters. Many foreign securities markets, especially those in emerging market countries, are less stable, smaller, less liquid, and less regulated than U.S. securities markets, and the costs of trading in those markets is often higher than in U.S. securities markets. There may also be less publicly available information about issuers of foreign securities compared to issuers of U.S. securities. In addition, the economies of certain foreign markets may not compare favorably with the economy of the United States with respect to issues such as growth of gross national product, reinvestment of capital, resources and balance of payments position.

•	Company risk - Investments in U.S. and/or foreign-traded equity securities may fluctuate more than the values of other types of securities in response to changes in a particular company's financial condition.

Performance. Performance for the Fund has not been included because the Fund commenced operations on the date of this Prospectus. Performance, which provides some indication of the risks of investing in the Fund, will be available once the Fund has completed one full calendar year of operations.

Sub-Adviser:
PPM America, Inc. ("PPM")

Portfolio Managers:

Purchase and Redemption of Fund Shares

Only separate accounts of Jackson National Life Insurance Company ("Jackson") or Jackson National Life Insurance Company of New York ("Jackson NY") and series, including fund of funds, of registered investment companies in which either or both of those insurance companies invest may purchase shares of the Fund. You may invest indirectly in the Fund through your purchase of a variable annuity or life insurance contract issued by a separate account of Jackson or Jackson NY that invests directly, or through a fund of funds, in this Fund. Any minimum initial or subsequent investment requirements and redemption procedures are governed by the applicable separate account through which you invest indirectly.

This Fund serves as an underlying investment by insurance companies, affiliated investment companies, and retirement plans for funding variable annuity and life insurance contracts and retirement plans.

Tax Information

The Fund expects to be treated as a partnership for U.S. federal income tax purposes, and does not expect to make regular distributions (other than in redemption of Fund shares) to shareholders, which generally are the participating insurance companies investing in the Fund through separate accounts of Jackson or Jackson NY and mutual funds owned directly or indirectly by such separate accounts. You should consult the prospectus of the appropriate separate account or description of the plan for a discussion of the U.S. federal income tax consequences to you of your contract, policy, or plan.

Payments to Broker-Dealers and Financial Intermediaries

If you invest in the Fund under a variable insurance contract or a plan that offers a variable insurance contract as a plan option through a broker-dealer or other financial intermediary (such as a financial institution), the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's Website for more information.
