JNL/DFA International Core Equity 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 27, 2026, as amended, are incorporated by reference into (which means they legally are a part of) this Summary Prospectus.

Investment Objective. The investment objective of the Fund is to achieve long-term 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.

2	JNAM has contractually agreed to waive 0.05% of the administrative fees of the Class. The fee waiver will continue for at least one year from the date of the current Prospectus, and continue thereafter unless the Board of Trustees approves a change in or elimination of the waiver. This fee waiver is subject to yearly review and approval by the Board of Trustees.

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. The example also assumes that the Class I administrative waiver is discontinued after one year. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

JNL/DFA International Core Equity Fund Class A
1 year	3 years	5 years	10 years
$93	$290	$504	$1,120

JNL/DFA International Core Equity Fund Class I
1 year	3 years	5 years	10 years
$57	$190	$335	$757

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.

Principal Investment Strategies. To achieve the Fund's investment objective, Dimensional Fund Advisors LP, the Fund's sub-adviser ("Sub-Adviser"), implements an integrated investment approach that combines research, portfolio design, portfolio management, and trading functions. As further described below, the Fund's design emphasizes long-term drivers of expected returns identified by the Sub-Adviser's research, while balancing risk through broad diversification across companies and sectors. The Sub-Adviser's portfolio management and trading processes further balance those long-term drivers of expected returns with shorter-term drivers of expected returns and trading costs.

The Fund is designed to purchase a broad and diverse group of equity securities within a market capitalization weighted universe (e.g., the larger the company, the greater the proportion of the universe it represents) of non-U.S. companies associated with developed markets that have been authorized for investment by the Sub-Advisor's Investment Committee (the "International Universe"). Under normal circumstances, the Fund will invest at least 80% of its assets (net assets plus the amount of any borrowings for investment purposes) in non-U.S. equity securities and/or investments that provide exposure to non-U.S. securities. The Fund invests in companies of all sizes, with meaningfully increased exposure to smaller capitalization, lower relative price, and higher profitability companies as compared to their representation in the International Universe. The Fund's meaningfully increased exposure to smaller capitalization, lower relative price, and higher profitability companies may be achieved by decreasing the allocation of the Fund's assets to larger capitalization, higher relative price, or lower profitability companies relative to their weight in the International Universe. An equity issuer is considered to have a high relative price (i.e., a growth stock) primarily because it has a high price in relation to its book value. An equity issuer is considered to have a low relative price (i.e., a value stock) primarily because it has a low price in relation to its book value. In assessing relative price, the Sub-Adviser may consider additional factors such as price to cash flow or price to earnings ratios. An equity issuer is considered to have high profitability because it has high earnings or profits from operations in relation to its book value or assets. The criteria the Sub-Adviser uses for assessing relative price and profitability are subject to change from time to time.

Under normal circumstances, the Fund intends to invest at least 40% of its assets in three or more non-U.S. countries by investing in securities of companies associated with such countries.

The Fund intends to purchase securities of companies associated with developed market countries that the Sub-Adviser has designated as approved markets. The Sub-Adviser determines company size on a country- or region-specific basis and based primarily on market capitalization. The Sub-Adviser may also increase or reduce the Fund's exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a company's price momentum, short-run reversals, and investment characteristics. In assessing a company's investment characteristics, the Sub-Adviser considers ratios such as recent changes in assets divided by total assets. The criteria the Sub-Adviser uses for assessing a company's investment characteristics are subject to change from time to time. In addition, the Sub-Adviser seeks to reduce trading costs using a flexible trading approach that looks for opportunities to participate in the available market liquidity, while managing turnover and explicit transaction costs.

The Fund may gain exposure to companies associated with approved markets by purchasing equity securities in the form of depositary receipts, which may be listed or traded outside the issuer's domicile country. The Fund also may purchase or sell futures contracts and options on futures contracts for foreign or U.S. equity securities and indices to increase or decrease equity market exposure based on actual or expected cash inflows to or outflows from the Fund. Because many of the Fund's investments may be denominated in foreign currencies, the Fund may enter into foreign currency exchange transactions, including foreign currency forward contracts, in connection with the settlement of foreign securities or to transfer cash balances from one currency to another currency.

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:

·

Equity securities risk - Common and preferred stocks represent equity ownership in a company. Stock markets are volatile, and equity securities generally have greater price volatility than fixed-income securities. The price of equity or equity-related securities will fluctuate and can decline and reduce the value of a portfolio investing in equity or equity-related securities. The value of equity or equity-related securities purchased or held by the Fund could decline if the financial condition of the companies the Fund invests in decline or if overall market and economic conditions deteriorate. They may also decline due to factors that affect a particular industry or industries, such as labor shortages or an increase in production costs and competitive conditions within an industry. In addition, they may decline due to general market conditions that are not specifically related to a company or industry, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates or generally adverse investor sentiment.

·

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.

·

Currency risk - Investments in foreign currencies, securities that trade in or receive revenues in foreign currencies, or derivatives that provide exposure to foreign currencies are subject to the risk that those currencies may decline in value or, in the case of hedging positions, that the currency may decline in value relative to the currency being hedged. Currency exchange rates can be volatile and may be affected by a number of factors, such as the general economics of a country, the actions (or inaction) of U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A decline in the value of a foreign currency versus the U.S. dollar reduces the value in U.S. dollars of investments denominated in that foreign currency.

·

Small-capitalization investing risk - Investing in smaller companies, some of which may be newer companies or start-ups, generally involves greater risks than investing in larger, more established ones. The securities of companies with smaller market capitalizations often are less widely held and trade less frequently and in lesser quantities, and their market prices often fluctuate more, than the securities of companies with larger market capitalizations.

·

Investment style risk - The returns from a certain investment style may be lower than the returns from the overall stock market. Value stocks may not increase in price if other investors fail to recognize the company's value or the factors that are expected to increase the price of the security do not occur. Over market cycles, different investment styles may sometimes outperform other investment styles (for example, growth investing may outperform value investing).

·

Profitability investment risk - High relative profitability stocks may perform differently from the market as a whole and following a profitability-oriented strategy may cause the Fund to at times underperform equity funds that use other investment strategies.

·

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.

·

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.

·

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.

·

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.

·

Stock risk - Stock markets may experience significant short-term volatility and may fall sharply at times. Different stock markets may behave differently from each other and U.S. stock markets may move in the opposite direction from one or more foreign

stock markets. The prices of individual stocks generally do not all move in the same direction at the same time and a variety of factors can affect the price of a particular company's stock.

·

Depositary receipts risk - Depositary receipts, such as American depositary receipts ("ADRs"), global depositary receipts ("GDRs"), and European depositary receipts ("EDRs"), may be issued in sponsored or un-sponsored programs. They may be traded in the over-the-counter ("OTC") market or on a regional exchange, or may otherwise have limited liquidity. The prices of depositary receipts may differ from the prices of securities upon which they are based. In a sponsored program, a security issuer has made arrangements to have its securities traded in the form of depositary receipts. In an un-sponsored program, the issuer may not be directly involved in the creation of the program. Holders of un-sponsored depositary receipts generally bear all the costs of the facility. The depository usually charges fees upon deposit and withdrawal of the underlying securities, the conversion of dividends into U.S. dollars or other currency, the disposition of non-cash distributions, and the performance of other services. Depositary receipts involve many of the same risks as direct investments in foreign securities. These risks include: fluctuations in currency exchange rates, which are affected by international balances of payments and other economic and financial conditions; government intervention; and speculation. With respect to certain foreign countries, there is the possibility of expropriation or nationalization of assets, confiscatory taxation, political and social upheaval, and economic instability. Investments in depositary receipts that are exchange-traded or OTC may also subject the Fund to liquidity risk. This risk is enhanced in connection with OTC depositary receipts.

·

Forward and futures contract risk - The successful use of forward and futures contracts draws upon the Sub-Adviser's skill and experience with respect to such instruments and are subject to special risks including, but not limited to: (a) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the forward or futures contract; (b) possible lack of a liquid market for a forward or futures contract and the resulting inability to close a forward or futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the Sub-Adviser's inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; (e) the possibility that the counterparty, clearing member or clearinghouse will default in the performance of its obligations; and (f) if the Fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements, and the Fund may have to sell securities at a time when it may be disadvantageous to do so.

Performance. The performance information shown provides some indication of the risks of investing in the Fund by showing changes in the Fund's performance from year to year and by showing how the Fund's average annual returns compared with those of a broad-based securities market index. Performance results include the effect of expense waiver/reduction arrangements for some or all of the periods shown, and if such arrangements had not been in place, performance for those periods would have been lower. The Fund's past performance is not necessarily an indication of how the Fund will perform in the future.

The returns shown in the bar chart and table do not include charges that will be imposed by variable insurance products. If these amounts were reflected, returns would be less than those shown.

Effective April 25, 2022, the Fund was combined with the JNL/BlackRock Advantage International Fund ("Acquired Fund"), with the Fund as the surviving Fund. The performance shown is the Fund's historical performance and does not reflect the performance of the Acquired Fund.

Purchase and Redemption of Fund Shares

Only separate accounts of Jackson National Life Insurance Company ("Jackson National") or Jackson National Life Insurance Company of New York ("Jackson National 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 National or Jackson National

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's shareholders are separate accounts of Jackson National or Jackson National NY and mutual funds owned directly or indirectly by such separate accounts. Accordingly, the Fund's dividends and other distributions generally are not taxable to you, the contract owner or plan participant, but no further discussion is included about the U.S. federal income tax consequences to you. 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.
