Summary Prospectus - April 29, 2024
JNL/Mellon Healthcare Sector 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 objective of the Fund is to track the performance of the Morningstar® US Healthcare IndexSM to provide total return through capital appreciation and dividend income.
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.

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. This example also assumes that the Class I administrative fee waiver is discontinued after one year. 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.

Principal Investment Strategies. The Fund invests under normal circumstances at least 80% of its assets (net assets plus the amount of any borrowings made for investment purposes) in the securities in the Morningstar US Healthcare Index ("Index") in proportion to their market capitalization weighting in the Index. The Index measures the performance of companies of biotechnology, pharmaceuticals, research services, home healthcare, hospitals, long-term care facilities, and medical equipment and supplies. The Index is float market capitalization weighted. The Index is reconstituted semiannually and implemented after the close of business on the third Friday of June and December and effective the following Monday. The Index is rebalanced quarterly and implemented after the close of business on the third Friday of March, June, September, and December and effective the following Monday. As of December 31, 2023, the Index had 160 constituents and the full market capitalization range was $2.41 billion to $553.37 billion. The number of securities is not fixed and can vary from reconstitution to reconstitution.
The Fund employs a passive investment approach, called indexing, which attempts to replicate the investment performance of the Index through representative sampling. Indexing may offer a cost-effective investment approach to gaining sector exposure over the long term. Indexing may eliminate the chance that a Fund will outperform the Index, but also may reduce some of the risk of active management, such as poor security selection.
The Fund's ability to achieve significant correlation with the performance of the Index may be affected by changes in shareholder flows, securities markets and changes in the composition of the Index.
The Fund may also invest in a combination of exchange-traded funds ("ETFs") and cash to maintain correlation to its index, to assist with index rebalances, and to meet redemption or purchase requests. The Fund's holdings are rebalanced on a quarterly basis to reflect changes in the composition of the Index.
The Fund may invest in financial futures, a type of derivative that may be used to obtain exposure to a variety of underlying assets, consistent with the Fund's investment objective and strategies, to provide liquidity for cash flows, to hedge dividend accruals or for other purposes that facilitate meeting the Fund's objective. The Fund's use of financial futures is intended to assist replicating the investment performance of the Index.
The Fund is "non-diversified" under the 1940 Act and may invest more of its assets in fewer issuers than "diversified" mutual funds. From time to time, the Index may become diversified. During those times, the Fund will continue to track the performance of the Index, but the Fund will retain its non-diversified status even if its holdings become diversified.
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.
Sector risk - Companies with similar characteristics may be grouped together in broad categories called sectors. Sector risk is the risk that securities of companies within specific sectors of the economy can perform differently than the overall market. For example, this may be due to changes in the regulatory or competitive environment or changes in investor perceptions regarding a sector. Because the Fund may allocate relatively more assets to certain sectors than others, the Fund's performance may be more susceptible to any developments which affect those sectors emphasized by the Fund. In addition, the Fund could underperform other funds investing in similar sectors or comparable benchmarks because of the investment manager's choice of securities within such sector.
Non-diversification risk - The Fund is non-diversified, as defined by the 1940 Act, and as such may invest in the securities of a limited number of issuers and may invest a greater percentage of its assets in a particular issuer. Therefore, a decline in the market price of a particular security held by the Fund may affect the Fund's performance more than if the Fund were a diversified investment company.
Concentration risk - The Fund may concentrate its investments in certain securities. To the extent that the Fund focuses on particular countries, regions, industries, sectors, issuers, types of investment or limited number of securities from time to time, the Fund may be subject to greater risks of adverse economic, business or political developments in the area of focus than a fund that invests in a wider variety of countries, regions, industries, sectors or investments.
License termination risk - The Fund may rely on licenses from a third party (licensor) that permit the Fund to use that party's intellectual property in connection with the Fund's name and/or investment strategies. The license may be terminated by the licensor, and as a result the Fund may lose its ability to use the licensed name or strategy, or receive important data from the licensor. Accordingly, a license may have a significant effect on the future operation of the Fund, including the need to change the investment strategy.
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.
Exchange-traded funds investing risk - An investment in an ETF generally presents the following risks: (i) the same primary risks as an investment in a conventional fund (i.e., one that is not exchange-traded) that has the same investment objectives, strategies and policies; (ii) the risk that an ETF may fail to accurately track the market segment or index that underlies its investment objective; (iii) price fluctuation, resulting in a loss to the Fund; (iv) the risk that an ETF may trade at a discount to its net asset value; (v) the risk that an active market for an ETF's shares may not develop or be maintained; and (vi) the risk that an ETF may no longer meet the listing requirements of any applicable exchanges on which that ETF is listed. When the Fund invests in an ETF, shareholders of the Fund bear their proportionate share of the ETF's fees and expenses as well as their share of the Fund's fees and expenses.
Passive investment risk - The Fund is not actively managed. Unlike with an actively managed fund, the Fund does not use techniques or defensive strategies designed to lessen the effects of market volatility or to reduce the impact of periods of market decline. This means that, based on market and economic conditions, the Fund's performance could be lower than actively managed funds that realign their portfolios more frequently based on the real-time market trends.
Index investing risk - The Fund's indexing strategy does not attempt to manage volatility, use defensive strategies, or reduce the effects of any long-term periods of poor stock performance. Should the Fund engage in index sampling, the performance of the securities selected will not provide investment performance tracking that of the Index. Fund performance may not exactly correspond with the performance of the relevant index for a number of reasons, including, but not limited to: the timing of purchases and redemptions of the Fund's shares, changes in the composition of the index, and the Fund's expenses. Certain regulatory limitations, such as fund diversification requirements, may limit the ability of the Fund to completely replicate an index.
Tracking error risk - Tracking error is the divergence of the Fund's performance from that of the Index. The Fund's return may not track the return of the Index for a number of reasons. Tracking error may occur because of differences between the securities and other instruments held in the Fund's portfolio and those included in the Index, pricing differences, differences in transaction costs, the Fund's holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or interest, tax gains or losses, changes to the Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Index does not. However, the Fund may be required to deviate its investments from the securities and relative weightings of the Index to comply with the 1940 Act, as amended to meet the issuer diversification requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies, or as a result of local market restrictions, or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Investment Adviser and its affiliates.
Mid-capitalization investing risk - The stocks of mid-capitalization companies can be more volatile and their shares can be less liquid than those of larger companies. Mid-capitalization companies may have limited product lines, markets or financial resources or may depend on the expertise of a few people and may be subject to more abrupt or erratic market movements than securities of larger, more established companies or the market averages in general. Securities of such issuers may lack sufficient market liquidity to effect sales at an advantageous time or without a substantial drop in price.
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.
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.


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. 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.
The performance data includes the performance of the JNL/Mellon Healthcare Sector Fund, then a series of the JNL Variable Fund LLC, for periods before the Fund's registration statement became effective.
Effective April 29, 2024, the Morningstar® US Market Extended Index℠ replaced the Morningstar® US Healthcare Index℠ as the Fund's broad-based securities market index in accordance with new regulatory disclosure requirements. The Morningstar® US Healthcare Index℠ is included as an additional index for the Fund because the Adviser believes it more closely reflects the market segments in which the Fund invests.

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.
