**Summary Prospectus – April 27, 2026**

**JNL/Dreyfus Government Money Market 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 <u>ProspectusRequest@jackson.com</u>. 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 as high a level of current income as is consistent with the preservation of capital and maintenance of liquidity.

**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:

**Principal Investment Strategies.** Under normal circumstances, the Fund seeks to achieve its investment objective by investing at least 99.5% of its total assets in cash, U.S. Government securities, and/or repurchase agreements that are "collateralized fully" (i.e., collateralized by cash or government securities). The government securities typically have a maximum remaining maturity of 397 calendar days and the repurchase agreements are collateralized by cash or government securities. 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 government securities or repurchase agreements collateralized by government securities. As a government money market fund, the Fund is exempt from requirements that permit money market funds to impose a liquidity fee. While the Fund's Board of Trustees may elect to subject the Fund to liquidity fee requirements in the future, the Board of Trustees has not elected to do so at this time.

The Fund seeks to maintain a stable net asset value of $1.00 per share, neither the Federal Deposit Insurance Company, nor any other government agency insures or protects your investment.

**Principal Risks of Investing in the Fund.** You could lose money by investing in the Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in the Fund is not a bank account and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund's sponsor is not required to reimburse the Fund for losses, and you should not expect that the sponsor will provide financial support to the Fund at any time, including during periods of market stress.

As with any mutual fund, the value of the Fund's shares will change, and you could lose money by investing in the Fund. While the Fund may hold securities that carry U.S. Government guarantees, these guarantees do not extend to shares of the Fund itself. The principal risks associated with investing in the Fund include:

· *Fixed-income risk* **–** The price of fixed-income securities responds to economic developments, particularly interest
rate changes, as well as to perceptions about the credit risk of individual issuers. Rising interest rates generally will cause the price
of bonds and other fixed-income debt securities to fall. Falling interest rates may cause an issuer to redeem, call or refinance a security
before its stated maturity, which may result in the Fund having to reinvest the proceeds in lower yielding securities. Bonds and other
fixed-income debt securities are subject to credit risk, which is the possibility that the credit strength of an issuer will weaken and/or
an issuer of a fixed-income security will fail to make timely payments of principal or interest and the security will go into default.
Debt instruments typically do not provide any voting rights, except in cases when interest payments have not been made and the issuer
is in default.

· *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.

· *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.

· *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.

· *Repurchase agreements, purchase and sale contracts risk –* If the other party to a repurchase agreement or purchase and
sale contract defaults on its obligation under the agreement, the Fund may suffer delays and incur costs or lose money in exercising its
rights under the agreement. If the seller fails to repurchase the security under a repurchase agreement or purchase and sale contract,
and the market value of the security declines, the Fund may lose money.

· *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.

<br> **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. 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.

Prior to September 19, 2016, the Fund was operated as a prime money market fund. Effective September 19, 2016, the Fund operates as a government money market fund and, as such, invests at least 99.5% of its total assets in cash, government securities and/or repurchase agreements that are "collateralized fully" (i.e., backed by cash or government securities). Performance prior to October 21, 2024 reflects the Fund's results when managed by the former sub-adviser, Wellington Management Company LLP.

The 7-day yield of Class A on December 31, 2025, was 3.27%.

The 7-day yield of Class I on December 31, 2025, was 3.57%.

**Portfolio Management.**

**Sub-Adviser:** <br> Mellon Investments Corporation ("Mellon")

**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.

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.
