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:

1 year	3 years	5 years	10 years
$122	$381	$660	$1,455

JNL Multi-Manager International Small Cap Fund Class I
1 year	3 years	5 years	10 years
$92	$287	$498	$1,108

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.

Period
1/1/2025 - 12/31/2025	116	%

Principal Investment Strategies. The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its assets (net assets plus the amount of any borrowings for investment purposes) in the equity securities of international companies that, when purchased, have market capitalizations between the smallest company and 120% of the largest company in the Morningstar Global ex-US Small Cap Target Market Exposure Index. As of December 31, 2025, the range of such companies in the Morningstar Global ex-US Small Cap Target Market Exposure Index was $273.95 million to $30.75 billion.

The Fund generally will invest in the securities of companies domiciled in at least three different countries. However, from time to time, the Fund may invest a significant portion of its assets in the securities of companies domiciled in one or a few countries. As of the date of the prospectus, the Fund invested significantly in securities of companies domiciled in Japan. The Fund maintains the flexibility to invest in securities of companies from a variety of sectors, but from time to time, the Fund may have significant investments in particular sectors, including but not limited to the industrials sector.

Equity securities represent an ownership interest, or the right to acquire an ownership interest, in an issuer. The equity securities in which the Fund may invest can be traded on an exchange or in over-the-counter markets and include common stocks (including depositary receipts evidencing ownership of common stock), preferred stocks and other preferred securities, convertible securities, rights and warrants, and other securities, such as hybrid securities and trust preferred securities, believed to have equity-like characteristics. The Fund's investments in depositary receipts may include American, European, Canadian and Global Depositary Receipts ("ADRs," "EDRs," "CDRs", and "GDRs," respectively), and other similar securities. ADRs are receipts that represent interests in foreign securities held on deposit by U.S. banks. EDRs and GDRs have the same qualities as ADRs, except that they may be traded in several international trading markets.

The Fund may participate in initial public offerings ("IPOs") and in securities offerings that are not registered in the U.S. In some emerging markets, the Fund may invest in companies that qualify as smaller companies but still are among the largest in that market.

The Fund may invest in Rule 144A and Regulation S securities. Rule 144A securities are securities offered as exempt from registration with the Securities and Exchange Commission ("SEC") but are typically treated as liquid securities because there is a market for such securities. Regulation S securities are securities of U.S. and non-U.S. issuers that are issued through private offerings without registration with the SEC pursuant to Regulation S under the Securities Act of 1933, as amended.

A company is considered to be in an emerging or frontier country or market if the company has been registered, incorporated, or organized under the laws of, has headquarters or its principal offices in, or has its stock exchange listing or its securities principally traded in, the emerging or frontier country or market, or if the company derives at least 50% of its revenues, net profits or incremental revenue growth (typically over the past five years) from, or has at least 50% of assets or production capacities in, the emerging or frontier country or market. The Fund considers a company to be domiciled in a country if the company is registered, incorporated or organized under the laws of that country, has headquarters or its principal place of business in that country, or has its stock exchange listing or its securities principally traded in that country.

Three unaffiliated investment managers ("Sub-Advisers") generally provide day to day management for a portion of the Fund's assets (each portion is sometimes referred to as a "sleeve"). Each Sub-Adviser may use different investment strategies in managing Fund assets, acts independently from the others, and uses its own methodology for selecting investments. Jackson National Asset Management, LLC ("JNAM" or "Adviser") is responsible for identifying and retaining the Sub-Advisers for the selected strategies and for monitoring the services provided by the Sub-Advisers. JNAM provides qualitative and quantitative supervision as part of its process for selecting and monitoring the Sub-Advisers. JNAM is also responsible for selecting the Fund's investment strategies and for determining the amount of Fund assets to allocate to each Sub-Adviser. Based on JNAM's ongoing evaluation of the Sub-Advisers, JNAM may adjust allocations among Sub-Advisers.

The Fund may use derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions. Derivative instruments that provide investment exposure to the investments above or exposure to one or more market risk factors associated with such investments are included in the Fund's 80% policy and are consistent with the Fund's investment policies and limitations with respect to investments in derivatives.

JNAM may choose to allocate the Fund's assets to additional Sub-Advisers or to replace/remove Sub-Advisers in the future. There is no assurance that any or all of the strategies discussed in this prospectus will be used by JNAM or the Sub-Advisers.

Below are the principal investment strategies for each Sub-Adviser's strategy, but the Sub-Advisers may also implement other investment strategies in keeping with their respective strategy's objective.

WCM Strategy

WCM Investment Management, LLC ("WCM") constructs the strategy by investing in equity securities or depositary receipts of small capitalization companies domiciled outside of the United States, including in emerging and frontier market countries.

Causeway Strategy

Causeway Capital Management LLC ("Causeway") constructs the strategy by investing primarily in common stocks of companies with smaller market capitalizations located in developed and emerging markets outside the U.S. The Causeway Strategy may invest in a wide range of industries.

FIAM Strategy

FIAM LLC ("FIAM") constructs the FIAM Strategy by investing primarily in non-U.S. securities, including securities of issuers located in emerging markets with small market capitalizations.

FIAM uses fundamental analysis of factors such as each issuer's financial condition and industry position, and market and economic conditions to select investments.

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:

·

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.

·

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.

·

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.

·

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. Growth stock prices frequently reflect projections of future earnings or revenues, and if earnings growth expectations are not met, their stock prices will likely fall, which may reduce the value of a Fund's investment in those stocks. Over market cycles, different investment styles may sometimes outperform other investment styles (for example, growth investing may outperform value investing).

·

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.

·

Frontier market countries risk - Frontier market countries generally have smaller economies and even less developed capital markets than traditional developing markets, and, as a result, the risks of investing in developing market countries are magnified in frontier market countries. The magnification of risks is the result of: potential for extreme price volatility and illiquidity in frontier markets; government ownership or control of parts of private sector and of certain companies; trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which frontier market countries trade; and the relatively new and unsettled securities laws in many frontier market countries.

·

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.

·

Allocation risk - The Fund's ability to achieve its investment objective depends upon the investment manager's analysis of such factors as macroeconomic trends, outlooks for various industries and asset class valuations, and its ability to select an appropriate mix of asset classes based on its analysis of such factors. The Fund is subject to the risk of changes in market, investment, and economic conditions in the selection and percentages of allocations.

·

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.

·

European investment risk - Investing in Europe involves many of the same risks as investing in foreign securities. In addition, since Europe includes both developed and emerging markets, investments by the Fund will be subject to the risks associated with investments in such markets. Performance is expected to be closely tied to social, political, and economic conditions within Europe and to be more volatile than the performance of more geographically diversified funds.

·

Japan investment risk - The Fund may invest a meaningful portion of its assets in Japan, the Fund's performance is expected to be closely tied to social, political, and economic conditions within Japan and to be more volatile than the performance of more geographically diversified funds.

·

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.

·

Investments in IPOs risk - IPOs issued by unseasoned companies with little or no operating history are risky and highly volatile.

·

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.

·

Regulation S securities risk - Regulation S securities may be less liquid than publicly traded securities and may not be subject to the disclosure and other investor protection requirements that would be applicable if they were publicly traded. Accordingly, Regulation S securities may involve a high degree of business and financial risk and may result in substantial losses.

·

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.

·

Securities lending risk - Securities lending involves the risk of loss or delays in recovery of the loaned securities or loss of rights in the collateral if the borrower fails to return the security loaned or becomes insolvent.

·

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.

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 and an additional index that the Adviser believes more closely reflects the market segments in which the Fund invests. 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 26, 2021, the Fund was combined with JNL/Franklin Templeton International Small Cap Fund ("Acquired Fund"), with the Fund as the surviving Fund. The performance shown is the Fund's historic 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.
