JACKSON NATIONAL LIFE INSURANCE COMPANY

JACKSON NATIONAL LIFE INSURANCE COMPANY OF NEW YORK

1 Corporate Way

Lansing, Michigan 48951

February 13, 2026

Dear Contract Owner:

Enclosed is a notice of a Special Meeting of Shareholders of the JNL/AQR Large Cap Defensive Style Fund (the "AQR Fund" or the "Acquired Fund"), a series of the JNL Series Trust (the "Trust"). The Special Meeting of Shareholders of the Acquired Fund is scheduled to be held at the offices of Jackson National Life Insurance Company ("Jackson National") , 1 Corporate Way, Lansing, Michigan 48951, on March 25, 2026, at 1:30 p.m., Eastern Time (the "Meeting"). At the Meeting, the shareholders of the Acquired Fund will be asked to approve the proposal described below.

The Trust's Board of Trustees (the "Board") called the Meeting to request shareholder approval of the reorganization (the "Reorganization") of the Acquired Fund into the JNL/DFA U.S. Core Equity Fund (the "DFA Fund" or the "Acquiring Fund"), also a series of the Trust. The Acquired Fund and the Acquiring Fund are each sometimes referred to herein as a "Fund" and collectively, the "Funds."

If the Reorganization is approved and implemented, each person that invests indirectly in the Acquired Fund will automatically become an investor indirectly in the Acquiring Fund. Both the Acquired Fund and the Acquiring Fund are managed by Jackson National Asset Management, LLC ("JNAM"), and each is sub-advised by an investment sub-adviser.

The Board considered that the AQR Fund was launched to provide investors with competitive market returns over the long-term, but with a lower degree of volatility. The Board also considered JNAM's statement that, with the exception of 2022, the AQR Fund's consistent underperformance since its inception in 2019 is the primary driver behind its recommendation to merge the AQR Fund into the DFA Fund. The Board considered the recommendation of JNAM to merge the AQR Fund into the DFA Fund given that the DFA Fund's superior risk-adjusted performance and more consistent performance versus peers than the AQR Fund, and because JNAM believes the existing shareholders of the AQR Fund will benefit from lower overall expenses, lower fees, economies of scale and should benefit from a history of more consistent and favorable performance achieved through the Reorganization with the DFA Fund.

After considering JNAM's recommendation, the Board concluded that: (i) the Reorganization will benefit the shareholders of the Acquired Fund; (ii) the Reorganization is in the best interests of the Acquired Fund; and (iii) the interests of the shareholders of the Acquired Fund will not be diluted as a result of the Reorganization. No one factor was determinative, and each Trustee may have attributed different weights to the various factors. The Board did not determine any considerations related to this Reorganization to be adverse. The Board, after careful consideration, approved the Reorganization.

Pending shareholder approval, effective as of the close of business on April 24, 2026, or on such later date as may be deemed necessary in the judgment of the Board in accordance with the Plan of Reorganization (the "Closing Date"), you will invest indirectly in shares of the Acquiring Fund in an amount equal to the dollar value of your interest in the Acquired Fund on the Closing Date. As of the date hereof, it is not expected that the Closing Date will be postponed. If the Closing Date is postponed to allow for additional time to solicit shareholder votes, shareholders will remain shareholders of their respective Fund(s). No sales charge, redemption fees, or other transaction fees will be imposed in the Reorganization. There will, however, be transaction costs associated with the Reorganization, which typically include, but are not limited to, trade commissions, related fees and taxes, and any foreign exchange spread costs. The Acquired Fund will bear the transaction expenses due to the portfolio repositioning based on its relative net asset value at the time of the Reorganization. Such costs are estimated to be $17,845 (0.004% of net assets). There is no tax impact to contract owners as a result of portfolio repositioning. Additionally, the repositioning is not expected to have a material impact on the performance of the Acquired Fund prior to the Reorganization. Following the Reorganization, the Acquired Fund will cease to exist and the Acquired Fund's performance will not be reflected in the performance of the Acquiring Fund. The Reorganization will not cause any fees or charges under your contract to be greater after the Reorganization than before the Reorganization, and the Reorganization will not alter your rights under your contract or the obligations of the insurance company that issued the contract. Following the Reorganization, the Acquiring Fund will be the accounting and performance survivor.

You may wish to take actions relating to your future allocation of premium payments under your insurance contract to the various investment divisions (the "Divisions") of the separate account issued by Jackson National or Jackson National Life Insurance Company of New York ("Jackson National NY") . You may execute certain changes prior to the Reorganization, in addition to participating in the Reorganization with regard to the Acquiring Fund, such as allocating your premium payments to other Divisions.

All actions with regard to the Acquired Fund need to be completed by the Closing Date. In the absence of new instructions prior to the Closing Date, future premium payments previously allocated to the Acquired Fund Division will be allocated to the Acquiring Fund Division. The Acquiring Fund Division will be the Division for future allocations under the Dollar Cost Averaging, Earnings Sweep, and Rebalancing Programs (together, the "Programs"). In addition to the Acquiring Fund Division, there are other Divisions investing in mutual funds that seek long-term capital appreciation. If you want to transfer all or a portion of your Contract value out of the Acquired Fund Division prior to the Reorganization, you may do so and that transfer will not be treated as a transfer for the purpose of determining how many subsequent transfers may be made in any period or how many may be made in any period without charge. In addition, if you want to transfer all or a portion of your Contract value out of the Acquiring Fund Division after the Reorganization, you may do so within 60 days following the Closing Date and that transfer will not be treated as a transfer for the purpose of determining how many subsequent transfers may be made in any period or how many may be made in any period without charge. You will be provided with an additional notification of this free-transfer policy on or about April 27, 2026.

If you want to change your allocation instructions as to your future premium payments or the Programs or if you require summary descriptions of the other underlying funds and Divisions available under your contract or additional copies of the prospectuses for other funds underlying the Divisions, please contact:

CONTRACT OWNER VOTING INSTRUCTIONS

REGARDING A SPECIAL MEETING OF SHAREHOLDERS OF

JNL/AQR LARGE CAP DEFENSIVE STYLE FUND

A SERIES OF THE JNL SERIES TRUST

TO BE HELD ON MARCH 25, 2026

DATED: FEBRUARY 13, 2026

GENERAL

These Contract Owner voting instructions are being furnished by Jackson National Life Insurance Company ("Jackson National"), or Jackson National Life Insurance Company of New York (each, an "Insurance Company" and, together, the "Insurance Companies"), to owners of their variable life insurance policies or variable annuity contracts or certificates (the "Contracts") (the "Contract Owners") who, as of January 31, 2026 (the "Record Date"), had net premiums or contributions allocated to the investment divisions of their separate accounts (the "Separate Accounts") that are invested in shares of the JNL/AQR Large Cap Defensive Style Fund (the "AQR Fund" or "Acquired Fund"), a series of the JNL Series Trust (the "Trust").

The Trust is a Massachusetts business trust registered with the Securities and Exchange Commission (the "SEC") as an open-end management investment company.

Each Insurance Company is required to offer Contract Owners the opportunity to instruct it, as the record owner of all of the shares of beneficial interest in the Acquired Fund (the "Shares") held by its Separate Accounts, as to how it should vote on the reorganization proposal (the "Proposal") to be considered at the Special Meeting of Shareholders of the Acquired Fund referred to in the preceding Notice and at any adjournments (the "Meeting"). The enclosed Proxy Statement and Prospectus, which you should retain for future reference, concisely sets forth information about the proposed reorganization involving the Acquired Fund and another series of the Trust that a Contract Owner should know before completing the enclosed voting instruction card.

These Contract Owner Voting Instructions and the accompanying voting instruction card are being mailed to Contract Owners on or about February 19, 2026.

HOW TO INSTRUCT AN INSURANCE COMPANY

To instruct an Insurance Company as to how to vote the Shares held in the investment divisions of its Separate Accounts, Contract Owners are asked to promptly complete their voting instructions on the enclosed voting instruction card(s) and sign, date, and mail the voting instruction card(s) in the accompanying postage-paid envelope. Contract Owners also may provide voting instructions by phone at 1-800-690-6903 or by Internet at our website at www.proxyvote.com.

If a voting instruction card is not marked to indicate voting instructions but is signed, dated, and returned, it will be treated as an instruction to vote the Shares in favor of the Proposal.

The number of Shares held in the investment division of a Separate Account corresponding to the Acquired Fund for which a Contract Owner may provide voting instructions was determined as of the Record Date by dividing (i) a Contract's account value (minus any Contract indebtedness) allocable to that investment division by (ii) the net asset value of one Share of the Acquired Fund. At any time prior to an Insurance Company's voting at the Meeting, a Contract Owner may revoke his or her voting instructions with respect to that investment division by providing the Insurance Company with a properly executed written revocation of such voting instructions, properly executing later-dated voting instructions by a voting instruction card, telephone or the Internet, or appearing and voting in person at the Meeting.

i

HOW AN INSURANCE COMPANY WILL VOTE

An Insurance Company will vote the Shares for which it receives timely voting instructions from Contract Owners in accordance with those instructions. Shares in each investment division of a Separate Account for which an Insurance Company receives a voting instruction card that is signed, dated, and timely returned but is not marked to indicate voting instructions will be treated as an instruction to vote the Shares in favor of the Proposal. Shares in each investment division of a Separate Account for which an Insurance Company receives no timely voting instructions from a Contract Owner, or that are attributable to amounts retained by an Insurance Company or its affiliate as surplus or seed money, will be voted by the applicable Insurance Company either for or against approval of the Proposal, or as an abstention, in the same proportion as the Shares for which Contract Owners (other than the Insurance Company) have provided voting instructions to the Insurance Company. Similarly, the Insurance Companies and their affiliates will vote their own shares and will vote shares that are held by the Fund of Funds whose shares are held by a Separate Account in the same proportion as voting instructions timely given by Contract Owners. As a result of proportionate voting, a small number of Contract Owners could determine the outcome of the Proposal. Please see "Additional Information about the Funds - Tax Status" below.

OTHER MATTERS

The Insurance Companies are not aware of any matters, other than the Proposal, to be acted on at the Meeting. If any other matters come before the Meeting, an Insurance Company will vote the Shares upon such matters in its discretion. Voting instruction cards may be solicited by employees of Jackson National or its affiliates as well as officers and agents of the Trust. The principal solicitation will be by mail, but voting instructions may also be solicited by telephone, personal interview, the Internet, or other permissible means.

The Meeting may be adjourned whether or not a quorum is present, by the chairperson of the Meeting from time to time to reconvene at the same or some other place as determined by the chairperson of the Meeting for any reason, including failure of a Proposal to receive sufficient votes for approval. No shareholder vote shall be required for any adjournment. No notice need be given that the Meeting has been adjourned other than by announcement at the Meeting. Any business that might have been transacted at the original Meeting may be transacted at any adjourned Meeting.

It is important that your Contract be represented. Please promptly mark your voting instructions on the enclosed voting instruction card; then sign, date, and mail the voting instruction card in the accompanying postage-paid envelope. You may also provide your voting instructions by phone at 1-800-690-6903 or by Internet at our website at www.proxyvote.com.

SUMMARY

You should read this entire Proxy Statement/Prospectus carefully. For additional information, you should consult the Plan of Reorganization, a copy of which is attached hereto as Appendix A.

The Proposed Reorganization

The proposed Reorganization is as follows:

Proposal Shareholders Entitled to Vote on
the Proposal
1.     To approve the Plan of Reorganization, adopted by the Board, which provides for the Reorganization of the AQR Fund into the DFA Fund.

Shareholders of the

AQR Fund

This Proxy Statement/Prospectus is soliciting shareholders with amounts invested in the Acquired Fund as of January 31, 2026, to approve the Plan of Reorganization, whereby the Acquired Fund will be reorganized into the Acquiring Fund. (The Acquired Fund and Acquiring Fund are each sometimes referred to herein as a "Fund" and collectively, the "Funds.")

If the Reorganization is not approved by shareholders, the Funds will continue to operate as they currently do and the Board will consider what actions are appropriate and in the best interests of Contract Owners that have assets invested in the Acquired Fund.

The Acquired Fund has two share classes, designated Class A and Class I shares ("Acquired Fund Shares"). The Acquiring Fund also has two share classes, designated Class A and Class I shares ("Acquiring Fund Shares").

The Plan of Reorganization provides for:

the transfer of all of the assets of the Acquired Fund to the Acquiring Fund in exchange for Acquiring Fund Shares having an aggregate net asset value equal to the Acquired Fund's net assets;
the Acquiring Fund's assumption of all the liabilities of the Acquired Fund;
the distribution to the shareholders (for the benefit of the Separate Accounts, as applicable, and thus the Contract Owners) of those Acquiring Fund Shares; and
the complete termination of the Acquired Fund.

A comparison of the investment objective(s), principal investment policies and strategies, and principal risks of the Acquired Fund and the Acquiring Fund is included in the "Comparison of Investment Objectives and Principal Investment Strategies," "Comparison of Principal Risk Factors," and "Comparison of Fundamental Policies" sections below. The Funds have identical distribution procedures, purchase procedures, exchange rights, and redemption procedures, which are discussed in "Additional Information about the Funds" below. Each Fund offers its shares to Separate Accounts and certain other eligible investors. Shares of each Fund are offered and redeemed at their net asset value without any sales load. You will not incur any sales loads or similar transaction charges as a result of the Reorganization.

The Reorganization is expected to be effective as of the close of business on April 24, 2026, or on such later date as may be deemed necessary in the judgment of the Board in accordance with the Plan of Reorganization (the "Closing Date"). As a result of the Reorganization, a shareholder invested in shares of the Acquired Fund would become an owner of shares of the Acquiring Fund. Such shareholder would hold, immediately after the Closing Date, Acquiring Fund Shares having an aggregate net asset value equal to the aggregate net asset value of the Acquired Fund Shares that were held by the shareholder as of the Closing Date. Similarly, each Contract Owner whose Contract values are invested indirectly in shares of the Acquired Fund through the Investment Divisions of a Separate Account would become indirectly invested in shares of the Acquiring Fund through the Investment Divisions of a Separate Account. The Contract value of each such Contract Owner would be invested indirectly through the Investment Divisions of a Separate Account, immediately after the Closing Date, in shares of the Acquiring Fund having an aggregate net asset value equal to the aggregate net asset value of the Acquired Fund Shares in which the Contract Owner invested indirectly through the Investment Divisions of a Separate Account as of the Closing Date. Following the Reorganization, the Acquiring Fund will be the accounting and legal survivor. It is expected that the Reorganization will not be a taxable event for U.S. federal income tax purposes for Contract Owners. Please see "Additional Information about the Reorganization - Federal Income Tax Consequences of the Reorganization" below for further information.

1

The Board unanimously approved the Plan of Reorganization with respect to the AQR Fund. Accordingly, the Board is submitting the Plan of Reorganization for approval by the Acquired Fund's shareholders. In considering whether to approve the proposal ("Proposal"), you should review the Proposal for the Acquired Fund in which you were invested on the Record Date (as defined under "Voting Information"). In addition, you should review the information in this Proxy Statement/Prospectus that relates to the Proposal and the Plan of Reorganization generally.

The Board recommends that you vote "FOR" the Proposal to approve the Plan of Reorganization.

PROPOSAL: APPROVAL OF THE PLAN OF REORGANIZATION WITH RESPECT TO THE REORGANIZATION OF THE AQR FUND INTO THE DFA FUND.

This Proposal requests the approval of AQR Fund shareholders of the Plan of Reorganization pursuant to which the AQR Fund will be reorganized into the DFA Fund.

In considering whether you should approve this Proposal, you should note that:

Investment Objectives. The Funds have different investment objectives. The AQR Fund seeks total return, which consists of capital appreciation and income, while the DFA Fund seeks long-term capital appreciation. For a detailed comparison of each Fund's investment policies and strategies, see "Comparison of Investment Objectives and Principal Investment Strategies" below and Appendix B.
Principal Investment Strategies. The Funds also have different principal investment strategies. The AQR Fund pursues a defensive investment style, meaning it seeks to participate in rising equity markets while mitigating downside risk in declining markets, while the DFA Fund seeks to balance long-term drivers of expected returns with shorter-term drivers of expected returns and trading costs. The AQR Fund is designed to purchase a broad and diverse group of securities of U.S. companies and pursues its objective by investing, under normal market conditions, at least 80% of its net assets (including any borrowings for investment purposes) in "Equity Instruments" of large-capitalization issuers, whereas under normal market conditions, the DFA Fund will invest at least 80% of its assets (net assets plus the amount of any borrowings made for investment purposes) in equity securities of U.S. companies. The AQR Fund primarily invests in large-capitalization issuers located in the U.S. but can invest in companies of any size and may invest in small- and mid-capitalization companies from time to time. AQR generally considers large-capitalization issuers to be those issuers with market capitalizations within the range of the Morningstar US Target Market Exposure Index at the time of purchase. As of December 31, 2025 , the market capitalization of the companies comprising the Morningstar® US Target Market Exposure Index ranged from $ 11.6 billion to $ 4.5 trillion. The DFA Fund invests in companies of all sizes, with increased exposure to smaller capitalization, lower relative price, and higher profitability companies as compared to their representation in the U.S. Universe. The DFA Fund's investments in smaller capitalization companies, some of which may be newer companies or start-ups, generally involves greater risks than investing in larger, more established ones predominately invested in by the AQR Fund. The DFA Fund generally defines the "U.S. Universe" as a market capitalization weighted set of U.S. operating companies listed on a securities exchange in the United States.

Additionally, the Equity Instruments in which the AQR Fund invests include common stock, preferred stock, warrants, exchange-traded funds that invest in equity securities, stock index futures, real estate investment trusts, and other derivative instruments where the reference asset is an equity security, and the AQR Fund may also invest in short-term instruments, including U.S. Government securities, bank certificates of deposit, money market instruments or funds, and such other liquid investments deemed appropriate by AQR, without limit for temporary defensive purposes, which are not corresponding investment strategies for the DFA Fund. The DFA Fund may purchase or sell futures contracts and options on futures contracts for 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, which is not a corresponding investment strategy for the AQR Fund. For a detailed comparison of each Fund's investment policies and strategies, see "Comparison of Investment Objectives and Principal Investment Strategies" below and Appendix B.

Fundamental Policies. The Funds have the same fundamental policies. For a detailed comparison of each Fund's fundamental investment policies, see "Comparison of Fundamental Policies" below.
Principal Risks. While there are some similarities in the risk profiles of the Funds, there are also some differences of which you should be aware. Each Fund's principal risks include company risk, derivatives risk, equity securities risk, managed portfolio risk, market risk, and stock risk. However, the AQR Fund is also subject to counterparty risk, forward and futures contract risk, hedging transactions risk, investment in other investment companies risk, large-capitalization investing risk, leverage risk, mid-capitalization investing risk, model risk, real estate investment risk, REIT investment risk, U.S. Government securities risk, and volatility risk, which are not principal risks of investing in the DFA Fund. In addition, the principal risks of investing in the DFA Fund include investment style risk, profitability investment risk, and small-capitalization investing risk, which are not principal risks of investing in the AQR Fund.

Investment Adviser and Other Service Providers. Jackson National Asset Management, LLC ("JNAM" or the "Adviser") serves as the investment adviser and administrator for each Fund and would continue to manage and administer the DFA Fund after the Reorganization. JNAM has received an exemptive order from the SEC that generally permits JNAM, with approval from the Board, to appoint, dismiss, and replace each Fund's unaffiliated sub-adviser(s) and to amend the advisory agreements between JNAM and the unaffiliated sub-advisers, without obtaining shareholder approval. However, any amendment to an advisory agreement between JNAM and the Trust that would result in an increase in the management fee rate specified in that agreement (i.e., the aggregate management fee) charged to a Fund will be submitted to shareholders for approval. JNAM has appointed AQR Capital Management, LLC ("AQR") as the sub-adviser to manage the assets of the AQR Fund, and Dimensional Fund Advisors LP ("DFA") as the sub-adviser to manage the assets of the DFA Fund. It is anticipated that DFA will continue to sub-advise the DFA Fund after the Reorganization. For a detailed description of JNAM, AQR, and DFA, please see "Additional Information about the Funds - The Adviser" and "Additional Information about the Funds - The Sub-Advisers" below.
Asset Base. The AQR Fund and DFA Fund had net assets of approximately $445.50 million and $1.30 billion, respectively, as of June 30, 2025. Thus, if the Reorganization had been in effect on that date, the combined Fund (the "Combined Fund") would have had net assets of approximately $1.74 billion (net of estimated transaction expenses).
Description of the Securities to be Issued. Class A Shareholders of the AQR Fund will receive Class A shares of the DFA Fund, and Class I Shareholders of the AQR Fund will receive Class I shares of the DFA Fund pursuant to the Reorganization. Shareholders will not pay any sales charges in connection with the Reorganization. Please see "Comparative Fee and Expense Tables," "Additional Information about the Reorganization," and "Additional Information about the Funds" below for more information.
Operating Expenses. Following the Reorganization, the total annual fund operating expense ratio and management fee for the DFA Fund are expected to be lower than that of the AQR Fund currently. For a more detailed comparison of the fees and expenses of the Funds, please see "Comparative Fee and Expense Tables" and "Additional Information about the Funds" below.

The maximum management fee for the AQR Fund is equal to an annual rate of 0.40% of its average daily net assets, while the maximum management fee for the DFA Fund is equal to an annual rate of 0.40% of its average daily net assets. The minimum management fee for the AQR Fund is equal to an annual rate of 0.35% of its average daily net assets over $5 billion, while the minimum management fee for the DFA Fund is equal to an annual rate of 0.35% of its average daily net assets over $5 billion. As of December 31, 2024, the actual management fees of the AQR Fund and the DFA Fund were 0.40% and 0.39% respectively. In addition, the maximum administrative fee for the AQR Fund is equal to an annual rate of 0.15% of its average daily net assets, while the maximum administrative fee for the DFA Fund is equal to an annual rate of 0.10% of its average daily net assets. As of December 31, 2024, the actual administrative fees of the AQR Fund and the DFA Fund were 0.15% and 0.10% respectively. For a more detailed description of the fees and expenses of the Funds, please see "Comparative Fee and Expense Tables" and "Additional Information about the Funds" below.

Costs of Reorganization. Following the Reorganization, the Combined Fund will be managed in accordance with the investment objective, policies and strategies of the DFA Fund. It is currently anticipated that approximately 30% of the AQR Fund's holdings will be transferred to the DFA Fund in connection with the Reorganization. Prior to the Reorganization, JNAM will likely use a transition manager to assist in the transition of the AQR Fund. It is anticipated that approximately 70% of the AQR Fund's holdings will be aligned or sold and the proceeds invested in securities that the DFA Fund wishes to hold. There is no tax impact to Contract Owners as a result of portfolio repositioning. Additionally, the repositioning is not expected to have a material impact on the performance of the AQR Fund prior to the Reorganization. Following the Reorganization, the AQR Fund will cease to exist and the AQR Fund's performance will not be reflected in the performance of the DFA Fund. It is not expected that the DFA Fund will revise any of its investment policies following the Reorganization to reflect those of the AQR Fund.

The costs and expenses associated with the Reorganization relating to the solicitation of proxies, including preparing, filing, printing, and mailing of the Proxy Statement/Prospectus and related disclosure documents, and the costs and expenses relating to obtaining a consent of an independent registered public accounting firm, will be borne by JNAM whether or not the Reorganization is consummated. The costs and expenses associated with the Reorganization relating to the legal fees, including the legal fees incurred in connection with the analysis under the Internal Revenue Code of 1986, as amended (the "Code") of the tax treatment of this transaction, as well as the costs associated with the preparation of the tax opinion, will be borne by the DFA Fund whether or not the Reorganization is consummated. No sales or other charges will be imposed on Contract Owners in connection with the Reorganization. The AQR Fund will bear transaction expenses, which typically include, but are not limited to, trade commissions, related fees and taxes, and any foreign exchange spread costs, where applicable (the "Transaction Costs"), associated with the Reorganization. Such Transaction Costs are estimated to be $17,845 (0.004% of net assets). Please see "Additional Information about the Reorganization" below for more information.

Federal Income Tax Consequences. The Reorganization is not expected to be a taxable event for U.S. federal income tax purposes for owners of variable contracts whose contract values are determined by investment in shares of the AQR Fund. Provided that the Contracts qualify to be treated as life insurance contracts under Section 7702(a) of the Code or annuity contracts under Section 72 of the Code, the Reorganization will not be a taxable event for federal income tax purposes for Contract Owners regardless of the tax status of the Reorganization, and any dividends declared, allocations or distributions in connection with the Reorganization will not be taxable to Contract Owners. The Insurance Companies, as shareholders, and Contract Owners are urged to consult with their own tax advisers as to the specific consequences to them of the Reorganizations, including the applicability and effect of any possible state, local, non-U.S. and other tax consequences of the Reorganization. Please see "Additional Information about the Reorganization - Federal Income Tax Consequences of the Reorganization" below for more information.

Comparative Fee and Expense Tables

The following tables show the current fees and expenses of each Fund and the estimated pro forma fees and expenses of Class A and Class I shares of the Acquiring Fund after giving effect to the proposed Reorganization. The fee and expense information is presented as of December 31, 2024. The tables below do not reflect any fees and expenses related to the Contracts, which would increase overall fees and expenses. See a Contract prospectus for a description of those fees and expenses.

3 JNAM has contractually agreed to waive 0.05% of the administrative fees of the DFA Fund Class I. 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 Examples

This example is intended to help you compare the costs of investing in the Funds with the cost of investing in other mutual funds. This example does not reflect fees and expenses related to the Contracts, and the total expenses would be higher if they were included. The example assumes that:

You invest $10,000 in a Fund for the time periods indicated;
Your investment has a 5% annual return;
The Fund's operating expenses remain the same as they were as of December 31, 2024;
You redeem your investment at the end of each time period; and
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:

1 JNAM has contractually agreed to waive 0.05% of the administrative fees of the DFA Fund Class I. 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.

Portfolio Turnover

Each 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 Examples, affect a Fund's performance. For the period ended June 30, 2025, the portfolio turnover rates for the AQR Fund and the DFA Fund were 13% and 1%, respectively, of the average value of each portfolio.

Comparison of Investment Objectives and Principal Investment Strategies

The following table compares the investment objectives and principal investment strategies of the AQR Fund with those of the DFA Fund. The Funds have different investment objectives. The AQR Fund seeks total return, which consists of capital appreciation and income, while the DFA Fund seeks long-term capital appreciation. The Funds also have different principal investment strategies. The AQR Fund pursues a defensive investment style, meaning it seeks to participate in rising equity markets while mitigating downside risk in declining markets, while the DFA Fund seeks to balance long-term drivers of expected returns with shorter-term drivers of expected returns and trading costs. The AQR Fund is designed to purchase a broad and diverse group of securities of U.S. companies and pursues its objective by investing, under normal market conditions, at least 80% of its net assets (including any borrowings for investment purposes) in "Equity Instruments" of large-capitalization issuers, whereas under normal market conditions, the DFA Fund will invest at least 80% of its assets (net assets plus the amount of any borrowings made for investment purposes) in equity securities of U.S. companies. The AQR Fund primarily invests in large-capitalization issuers located in the U.S. but can invest in companies of any size and may invest in small- and mid-capitalization companies from time to time. AQR generally considers large- capitalization issuers to be those issuers with market capitalizations within the range of the Morningstar US Target Market Exposure Index at the time of purchase. As of December 31, 2025 , the market capitalization of the companies comprising the Morningstar® US Target Market Exposure Index℠ ranged from $ 11.6 billion to $ 4.5 trillion. Whereas, the DFA Fund invests in companies of all sizes, with increased exposure to smaller capitalization, lower relative price, and higher profitability companies as compared to their representation in the U.S. Universe. The DFA Fund, by 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 predominately invested in by the AQR Fund. The DFA Fund generally defines the "U.S. Universe" as a market capitalization weighted set of U.S. operating companies listed on a securities exchange in the United States.

4

Additionally, the Equity Instruments in which the AQR Fund invests include common stock, preferred stock, warrants, exchange-traded funds that invest in equity securities, stock index futures, real estate investment trusts, and other derivative instruments where the reference asset is an equity security, and the AQR Fund may also invest in short-term instruments, including U.S. Government securities, bank certificates of deposit, money market instruments or funds, and such other liquid investments deemed appropriate by AQR, without limit for temporary defensive purposes, which are not corresponding investment strategies for the DFA Fund. The DFA Fund may purchase or sell futures contracts and options on futures contracts for 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, which is not a corresponding investment strategy for the AQR Fund.

The Board may change the investment objective of a Fund without a vote of the Fund's shareholders. For more detailed information about each Fund's investment strategies and risks, see below and Appendix B.

Acquired Fund Acquiring Fund
AQR Fund DFA Fund

Investment Objective

The investment objective of the Fund is to seek total return. Total return consists of capital appreciation and income.

Investment Objective

The investment objective of the Fund is long-term capital appreciation.

Principal Investment Strategies

The Fund pursues a "defensive" investment style, seeking to provide downside protection with upside potential through active stock selection, risk management, and diversification.

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 pursues its objective by investing, under normal market conditions, at least 80% of its net assets (including any borrowings for investment purposes) in "Equity Instruments" of large-capitalization issuers. The Fund primarily invests in large-capitalization issuers located in the United States. Equity Instruments include common stock, preferred stock, warrants, exchange-traded funds that invest in equity securities, stock index futures, real estate investment trusts, and other derivative instruments where the reference asset is an equity security. As of the date of this prospectus, AQR Capital Management, LLC, the Fund's sub-adviser ("Sub-Adviser"), generally considers large-cap issuers to be those issuers with market capitalizations within the range of the Morningstar US Target Market Exposure Index at the time of purchase. As of December 31, 2025 , the market capitalization of the companies comprising the Morningstar® US Target Market Exposure Index℠ ranged from $ 11.6 billion to $ 4.5 trillion. The Fund can invest in companies of any size and may invest in small- and mid-cap companies from time to time in the discretion of the Sub-Adviser. The Fund is designed to purchase a broad and diverse group of securities of U.S. companies. Under normal market conditions, the Fund will invest at least 80% of its assets (net assets plus the amount of any borrowings made for investment purposes) in equity securities of U.S. companies. The Sub-Adviser generally defines a U.S. company as one that is listed and principally traded on a securities exchange in the United States that is deemed appropriate by the Sub-Adviser. The Fund invests in companies of all sizes, with increased exposure to smaller capitalization, lower relative price, and higher profitability companies as compared to their representation in the U.S. Universe. The Sub-Adviser generally defines the "U.S. Universe" as a market capitalization weighted set (e.g., the larger the company, the greater the proportion of the U.S. Universe it represents) of U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the Sub-Adviser.

Acquired Fund Acquiring Fund
AQR Fund DFA Fund
The Fund pursues a defensive investment style, meaning it seeks to participate in rising equity markets while mitigating downside risk in declining markets. In other words, the Fund expects to lag the performance of traditional U.S. equity funds when equity markets are rising but to exceed the performance of traditional U.S. equity funds during equity market declines. To achieve this result, the Fund will be broadly diversified across companies and industries and will invest in companies such that the Sub-Adviser believes will result in a portfolio that exhibits low measures of risk and high quality (e.g., holds stable companies in good business health). The Fund's 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 U.S. 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.
The Fund is actively managed, and the Sub-Adviser will vary the Fund's exposures to issuers and industries based on the Sub-Adviser's evaluation of investment opportunities. In constructing the portfolio, the Sub-Adviser uses quantitative models, which combine active management to identify quality companies and statistical measures of risk to assure diversification by issuer and industry, as well as additional criteria that form part of the Sub-Adviser's security selection process. The Sub-Adviser uses volatility and correlation forecasting and other portfolio construction methodologies to manage the Fund. The Sub-Adviser utilizes quantitative risk models in furtherance of the Fund's investment objective, which seek to control portfolio level risk. Shifts in allocations among issuers and industries will be determined using the quantitative models based on the Sub-Adviser's determinations of risk and quality, as well as other factors including, but not limited to, managing industry and sector exposures. The percentage allocation of the assets of the Fund to securities of the largest U.S. high relative price companies will generally be reduced from between 2.5% and 25% of their percentage weight in the U.S. Universe. The percentage by which the Fund's allocation to securities of the largest U.S. high relative price companies is reduced will change due to market movements and other factors. 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 invests significantly in common stocks. The Fund may also invest in or use financial futures contracts as well as exchange-traded funds and similar pooled investment vehicles for hedging purposes, to gain exposure to the equity market and to maintain liquidity to pay for redemptions. The Fund may invest in short-term instruments, including U.S. Government securities, bank certificates of deposit, money market instruments or funds, and such other liquid investments deemed appropriate by the Sub-Adviser. The Fund may invest in these securities without limit for temporary defensive purposes. The Fund may purchase or sell futures contracts and options on futures contracts for 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.

Comparison of Principal Risk Factors

While there are some similarities in the risk profiles of the Funds, there are also some differences of which you should be aware. Each Fund's principal risks include company risk, derivatives risk, equity securities risk, managed portfolio risk, market risk, and stock risk. However, the AQR Fund is also subject to counterparty risk, forward and futures contract risk, hedging transactions risk, investment in other investment companies risk, large-capitalization investing risk, leverage risk, mid-capitalization investing risk, model risk, real estate investment risk, REIT investment risk, U.S. Government securities risk, and volatility risk, which are not principal risks of investing in the DFA Fund. In addition, the principal risks of investing in the DFA Fund include investment style risk, profitability investment risk, and small-capitalization investing risk, which are not principal risks of investing in the AQR Fund.

An investment in a Fund is not guaranteed. As with any mutual fund, the value of a Fund's shares will change, and an investor could lose money by investing in a Fund. The following table compares the principal risks of an investment in each Fund. For additional information about each principal risk and other applicable risks, see Appendix B.

Comparison of Fundamental Policies

Each Fund is subject to certain fundamental policies and restrictions that may not be changed without shareholder approval. The following table compares the fundamental policies of the AQR Fund with those of the DFA Fund.

Acquired Fund Acquiring Fund
AQR Fund DFA Fund
(1)    The Fund is a "diversified company," as such term is defined under the 1940 Act.

Same.

(2)    The Fund will not invest more than 25% of the value of its assets in any particular industry (other than U.S. Government securities and/or foreign sovereign debt securities).

Same.

(3)    The Fund may not invest directly in real estate or interests in real estate; however, the Fund may own debt or equity securities issued by companies engaged in those businesses. Same.
(4)    The Fund may not purchase or sell physical commodities other than foreign currencies unless acquired as a result of ownership of securities (but this limitation shall not prevent the Fund from purchasing or selling options, futures, swaps and forward contracts or from investing in securities or other instruments backed by physical commodities). Same.
(5)   The Fund may not lend any security or make any other loan if, as a result, more than 33 1/3% of the Fund's total assets would be lent to other parties (but this limitation does not apply to purchases of commercial paper, debt securities or repurchase agreements). Same.

8

(6)   The Fund may not act as an underwriter of securities issued by others, except to the extent that the Fund may be deemed an underwriter in connection with the disposition of portfolio securities of the Fund. Same.
(7)    The Fund may not invest more than 15% of its net assets in illiquid securities. Same.
(8)    The Fund may not borrow money, except to the extent permitted by the 1940 Act, the rules and regulations thereunder, and any applicable exemptive relief. Same.
(9)    The Fund may not issue senior securities, except to the extent permitted by the 1940 Act, the rules and regulations thereunder, and any applicable exemptive relief.* Same.
* Currently, under the 1940 Act, a "senior security" does not include any promissory note or evidence of indebtedness where the indebtedness is for temporary purposes only and in an amount not exceeding 5% of the value of the total assets of the issuer at the time the loan is made. A loan is presumed to be for temporary purposes if it is repaid within 60 days and is not extended or renewed.

Comparative Performance Information

The performance information shown below provides some indication of the risks of investing in each Fund by showing changes in each Fund's performance from year to year and by showing how each Fund's average annual returns compared with those of a broad-based securities market index. For the DFA Fund, 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. Each Fund's past performance is not necessarily an indication of how the Fund will perform in the future.

The returns shown in the bar charts and tables below do not include charges imposed under the Contracts. If these amounts were reflected, returns would be less than those shown.

Following the Reorganization, the Acquiring Fund will be the accounting and performance survivor.

Capitalization

The following table shows the capitalization of each Fund as of December 1, 2025, and of the DFA Fund on a pro forma combined basis as of December 1, 2025 after giving effect to the proposed Reorganization. The actual net assets of the AQR Fund and the DFA Fund on the Closing Date will differ due to fluctuations in net asset values, subsequent purchases, and redemptions of shares. No assurance can be given as to how many shares of the DFA Fund will be received by shareholders of AQR Fund on the Closing Date, and the following table should not be relied upon to reflect the number of shares of the DFA Fund that will actually be received.

(a) The costs and expenses associated with the Reorganization relating to the solicitation of proxies, including preparing, filing, printing, and mailing of the Proxy Statement/Prospectus and related disclosure documents, and the costs and expenses relating to obtaining a consent of an independent registered public accounting firm, will be borne by JNAM whether or not the Reorganization is consummated. The costs and expenses associated with the Reorganization relating to the legal fees, including the legal fees incurred in connection with the analysis under the Code of the tax treatment of this transaction, as well as the costs associated with the preparation of the tax opinion, will be borne by the Acquiring Fund whether or not the Reorganization is consummated. Such legal fees are estimated to be $22,000 (0.002% of net assets). No sales or other charges will be imposed on Contract Owners in connection with the Reorganization. It is currently anticipated that approximately 30% of the Acquired Fund's holdings will be transferred to the Acquiring Fund in connection with the Reorganization. Prior to the Reorganization, JNAM will likely use a transition manager to assist in the transition of the Acquired Fund. It is anticipated that approximately 70% of the Acquired Fund's holdings will be aligned or sold and the proceeds invested in securities that the Acquiring Fund wishes to hold. The Acquired Fund will bear the Transaction Costs associated with the Reorganization. Such Transaction Costs are estimated to be $17,845 (0.004% of net assets).
(b) The adjustment to the pro forma shares outstanding number represents a decrease in shares outstanding of the Acquiring Fund to reflect the exchange of shares of the Acquired Fund.

The Reorganization provides for the acquisition of all the assets and all the liabilities of the AQR Fund by the DFA Fund. If the Reorganization had taken place on December 1, 2025, shareholders of the AQR Fund would have received 12,358,293 and 291,935 Class A and Class I shares, respectively, of the DFA Fund.

After careful consideration, the Board unanimously approved the Plan of Reorganization with respect to the AQR Fund. Accordingly, the Board has submitted the Plan of Reorganization for approval by the AQR Fund's shareholders. The Board recommends that you vote "FOR" this Proposal.

ADDITIONAL INFORMATION ABOUT THE REORGANIZATION

Terms of the Plan of Reorganization

The terms of the Plan of Reorganization are summarized below. For additional information, you should consult the Plan of Reorganization, a copy of which is attached as Appendix A.

If shareholders of the Acquired Fund approve the Plan of Reorganization, then the assets of the Acquired Fund will be acquired by, and in exchange for, Class A and Class I shares, respectively, of the Acquiring Fund and the liabilities of the Acquired Fund will be assumed by the Acquiring Fund. The Acquired Fund will then be terminated by the Trust, and the Class A and Class I shares of the Acquiring Fund distributed to the Class A and Class I shareholders, respectively, of the Acquired Fund in the redemption of the Class A and Class I Acquired Fund Shares. Immediately after completion of the Reorganization, the number of shares of the Acquiring Fund then held by former shareholders of the Acquired Fund may be different than the number of shares of the Acquired Fund that had been held immediately before completion of the Reorganization, but the total investment will remain the same (i.e., the total value of the Acquiring Fund shares held immediately after the completion of the Reorganization will be the same as the total value of the Acquired Fund shares formerly held immediately before completion of the Reorganization).

It is anticipated that the Reorganization will be consummated as of the close of business on April 24, 2026, or on such later date as may be deemed necessary in the judgment of the Board and in accordance with the Plan of Reorganization, subject to the satisfaction of all conditions precedent to the closing. It is not anticipated that the Acquired Fund will hold any investment that the Acquiring Fund would not be permitted to hold ("non-permitted investments").

Description of the Securities to Be Issued

The Class A shareholders of the Acquired Fund will receive Class A shares of the Acquiring Fund, and the Class I shareholders of the Acquired Fund will receive Class I shares of the Acquiring Fund in accordance with the procedures provided for in the Plan of Reorganization. Each such share will be fully paid and non-assessable by the Trust when issued and will have no preemptive or conversion rights.

The Trust may issue an unlimited number of full and fractional shares of beneficial interest of the Acquiring Fund and divide or combine such shares into a greater or lesser number of shares without thereby changing the proportionate beneficial interests in the Trust. Each share of the Acquiring Fund represents an equal proportionate interest in that Fund with each other share. The Trust reserves the right to create and issue any number of Fund shares. In that case, the shares of the Acquiring Fund would participate equally in the earnings, dividends, and assets of the Fund. Upon liquidation of the Acquiring Fund, shareholders are entitled to share proportionally (according to the net asset value of their shares of the Acquiring Fund) in the net assets of the Fund available for distribution to shareholders. The Acquiring Fund is a series of the Trust.

The Trust currently offers two classes of shares, Class A and Class I shares, for the Acquired Fund and the Acquiring Fund. Each series of the Trust has adopted a distribution plan in accordance with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the distribution plan, Class A shares of the Acquired Fund and Acquiring Fund are charged a Rule 12b-1 fee at the annual rate of 0.30% of the average daily net assets attributable to the Class A shares of the respective Fund. Because these distribution/service fees are paid out of the Funds' assets on an ongoing basis, over time these fees will increase your cost of investing and may cost more than paying other types of charges. Class I shares are not charged a Rule 12b-1 fee.

Board Considerations

At a meeting of the Board held on December 10-11, 2025 (the "Board Meeting"), the Board, including all of the independent trustees who are not interested persons of the Funds (as defined in the Investment Company Act of 1940, as amended) (the "Independent Trustees"), considered information relating to the proposed reorganization of the Acquired Fund, a series of the Trust, into the Acquiring Fund, also a series of the Trust (the "Reorganization"). Before approving the Reorganization, the Independent Trustees reviewed the foregoing information with their independent legal counsel and with management, reviewed with independent legal counsel applicable law and their duties in considering such matters, and met with independent legal counsel in a private session without management present.

The Board considered that the Acquired Fund was launched to provide investors with competitive market returns over the long-term, but with a lower degree of volatility. The Board considered that the Reorganization is part of an overall rationalization of the Trust's offerings and is designed to eliminate inefficiencies arising from offering overlapping funds with similar investment objectives and investment strategies that serve as investment options for the Contracts issued by the Insurance Companies and certain non-qualified plans. The Board also considered that the Reorganization also seeks to increase assets under management in the Acquiring Fund in an effort to achieve additional economies of scale for beneficial owners of the Acquired Fund. The Board noted that the objective of the Reorganization is to seek to ensure that a consolidated family of investments offers a streamlined, complete, and competitive set of underlying investment options to serve the interests of shareholders and Contract Owners. The Board also considered JNAM's statement that, with the exception of 2022, the Acquired Fund's consistent underperformance since its inception in 2019 is the primary driver behind its recommendation to merge the Acquired Fund into the Acquiring Fund. The Board considered the recommendation of JNAM to merge the Acquired Fund into the Acquiring Fund given the Acquiring Fund's superior risk-adjusted performance and more consistent performance versus peers than the Acquired Fund, and because JNAM believes the existing shareholders of the Acquired Fund will benefit from lower overall expenses, lower fees, economies of scale and should benefit from a history of more consistent and favorable performance achieved through the Reorganization with the Acquiring Fund.

The Board considered a number of principal factors presented at the time of the Board Meeting in reaching its determinations, including the following:

Investment Objectives and Investment Strategies. The Board considered that the Reorganization will permit the Contract Owners and others with beneficial interest in the Acquired Fund to continue to invest in a professionally managed fund that focuses on U.S. large blend investments, while noting that the Acquired Fund's investment objective is different than that of the Acquiring Fund. The Acquired Fund seeks total return, which consists of capital appreciation and income, while the Acquiring Fund seeks long-term capital appreciation. In addition, the Board considered the differences between the Funds' principal investment strategies, while also considering management's expectation that the Acquiring Fund's enhanced index-like portfolio construction process will be added to the Acquired Fund's investment process. The Board considered JNAM's belief that the existing shareholders of the Acquired Fund will benefit from the investment process of the Acquiring Fund. For a full description of the investment objectives and investment strategies of the Acquired Fund and Acquiring Fund, see "Comparison of Investment Objectives and Principal Investment Strategies."

13

Operating Expenses. The Board considered that, if approved by the Acquired Fund's shareholders, the Reorganization is expected to result in a Combined Fund with a total annual fund operating expense ratio and management fee that are expected to be lower than those of the Acquired Fund currently. The Board further noted that the Acquiring Fund's total annual fund operating expense ratio and management fee are expected to remain the same a result of the Reorganization. See "Comparative Fee and Expense Tables."
Larger Asset Base. The Board considered that the Reorganization may benefit Contract Owners and others with beneficial interests in the Acquired Fund by allowing them to invest in the Combined Fund that has a larger asset base than that of the Acquired Fund currently. The Board noted that as of September 30, 2025, the Acquired Fund had assets of approximately $437.61 million as compared to assets of $1.32 billion for the Acquiring Fund. The Board considered that reorganizing the Acquired Fund into the Acquiring Fund offers Contract Owners and other investors the ability to benefit from economies of scale.
Performance. The Board considered the Funds' Class A shares performance, noting that the Acquiring Fund has had a better performance track record than the Acquired Fund for the quarter, one-, three- and five-year periods ended September 30, 2025, while the Acquired Fund had a better performance track record than the Acquiring Fund for the year-to-date period ended September 30, 2025. The Board noted that during the 2024 calendar year, the Acquiring Fund returned 20.40%, while the Acquired Fund returned 15.32%. The Board also noted that the Acquiring Fund had better performance than the Acquired Fund for the 2023, 2022 and 2021 calendar years.
Investment Adviser and Other Service Providers. The Board considered that the Funds currently have the same investment adviser and administrator, JNAM, and many of the same service providers, with the exception of having different sub-advisers and custodians. Specifically, the Board considered that the Acquired Fund is sub-advised by AQR, and that the sub-adviser for the Acquiring Fund is DFA. See "Comparison of Investment Adviser and Sub-Advisers." The Board also noted that the custodian for the Acquired Fund is JPMorgan Chase Bank, N.A., and the custodian for the Acquiring Fund is State Street Bank & Trust Company. Board also considered that the transfer agent for the Acquiring Fund, JNAM, and the Distributor for shares of the Acquiring Fund, Jackson National Life Distributors LLC ("JNLD"), are the same as for the Acquired Fund and will remain the same immediately after the Reorganization.
Federal Income Tax Consequences. The Board considered that the Reorganization is not expected to be a taxable event for U.S. federal income tax purposes for Contract Owners.
Costs of Reorganization. The Board considered that the costs and expenses associated with the Reorganization relating to the solicitation of proxies, including preparing, filing, printing, and mailing of the Proxy Statement/Prospectus and related disclosure documents, and the costs and expenses relating to obtaining a consent of an independent registered public accounting firm, will be borne by JNAM whether or not the Reorganization is consummated. The Board also considered that the costs and expenses associated with the Reorganization relating to the legal fees, including the legal fees incurred in connection with the analysis under the Code of the tax treatment of this transaction, as well as the costs associated with the preparation of the tax opinion, will be borne by the Acquiring Fund whether or not the Reorganization is consummated. No sales or other charges will be imposed on Contract Owners in connection with the Reorganization. The Board considered that it is currently anticipated that approximately 30% of the Acquired Fund's holdings will be transferred to the Acquiring Fund in connection with the Reorganization and that, prior to the Reorganization, JNAM will likely use a transition manager to align or sell approximately 70% of the Acquired Fund's holdings and invest the proceeds in securities that the Acquiring Fund wishes to hold. Thus, the Board considered that the Acquired Fund will bear the Transaction Costs associated with the Reorganization and that such Transaction Costs are estimated to be $17,845 (0.004% of net assets).

In summary, in determining whether to recommend approval of the Reorganization, the Board considered factors including (1) the terms and conditions of the Reorganization and whether the Reorganization would result in dilution of the Acquired Fund's and Acquiring Fund's shareholders', Contract Owners', and plan participants' interests; (2) the compatibility of the Funds' investment objectives, investment strategies, and investment restrictions, as well as shareholder services offered by the Funds; (3) the expense ratios and information regarding the fees and expenses of the Funds; (4) the advantages and disadvantages to the Acquired Fund's and Acquiring Fund's shareholders, Contract Owners, and plan participants of having a larger asset base in the Combined Fund; (5) the relative historical performance of the Funds; (6) the management of the Funds; (7) the U.S. federal income tax consequences of the Reorganization; and (8) the costs of the Reorganization. No one factor was determinative and each Trustee may have attributed different weights to the various factors. The Board did not determine any considerations related to the Reorganization to be adverse.

14

The Board, including the Independent Trustees, determined that the Reorganization would be in the best interests of the Acquired Fund and Acquiring Fund and that the interests of the Acquired Fund's and Acquiring Fund's Contract Owners and other investors would not be diluted as a result of the Reorganization. The Board voted unanimously to approve the Reorganization and recommended its approval by Contract Owners and others with beneficial interests in the Acquired Fund.

If the Reorganization is not approved by shareholders, the Funds will continue to operate as they currently do. While the Board has made no determination regarding this contingency, the Board will consider what actions are appropriate and in the best interests of Contract Owners that have assets invested in the Acquired Fund.

Description of Risk Factors

A Fund's performance may be affected by one or more risk factors. For a detailed description of each Fund's risk factors, please see "More Information on Strategies and Risk Factors" in Appendix B.

Federal Income Tax Consequences of the Reorganization

As a condition to the consummation of the Reorganization, each Fund will have received one or more opinions of Ropes & Gray LLP, dated on or before the effective date of the Reorganization, substantially to the effect that, on the basis of the existing provisions of the Code, U.S. Treasury regulations issued thereunder, current administrative rules, pronouncements and court decisions, for U.S. federal income tax purposes, the Reorganization will not be a taxable event for Contract Owners whose contract values are determined by investment in shares of the Acquired Fund. The opinion will be based on certain factual certifications made by officers of the Funds, the Adviser and the Insurance Companies offering the Contracts, and will also be based on reasonable assumptions.

None of the Trust, the Acquired Fund, or the Acquiring Fund has sought a tax ruling from the Internal Revenue Service (the "IRS"), but each is acting in reliance upon the opinions of counsel discussed in the previous paragraph. The opinions are not binding on the IRS and do not preclude the IRS from adopting a contrary position. Contract Owners should consult their own tax advisors concerning the potential tax consequences, including state and local income taxes.

Contingency Plan

If the Reorganization is not approved by shareholders, the Funds will continue to operate as they currently do and the Board will consider what actions are appropriate and in the best interests of Contract Owners that have assets invested in the Acquired Fund.

ADDITIONAL INFORMATION ABOUT THE FUNDS

Management of the Trust

This section provides information about the Trust, the Adviser, and the sub-advisers for the Funds.

The Trust

The Trust is organized as a Massachusetts business trust and is registered with the SEC as an open-end management investment company. Under Massachusetts law and the Trust's Declaration of Trust and By-Laws, the management of the business and affairs of the Trust is the responsibility of its Board. Each Fund is a series of the Trust.

The Adviser

JNAM, located at 1 Corporate Way, Lansing, Michigan 48951, serves as the investment adviser to the Trust and provides the Funds with professional investment supervision and management. JNAM is registered with the SEC under the Investment Advisers Act of 1940, as amended. JNAM is an indirect, wholly owned subsidiary of Jackson Financial Inc. ("Jackson"), a leading provider of retirement products for industry professionals and their clients. Jackson and its affiliates offer variable, fixed and fixed index annuities designed for tax-efficient growth and distribution of retirement income for retail customers, as well as products for institutional investors.

15

JNAM acts as investment adviser to the Trust pursuant to an Investment Advisory and Management Agreement. Under the Investment Advisory and Management Agreement, JNAM is responsible for managing the affairs and overseeing the investments of the Funds and determining how voting and other rights with respect to securities owned by the Funds will be exercised. JNAM also provides recordkeeping, administrative and exempt transfer agent services to the Funds and oversees the performance of services provided to the Funds by other service providers, including the custodian and shareholder servicing agent. JNAM is authorized to delegate certain of its duties with respect to a Fund to a sub-adviser, subject to the approval of the Board, and is responsible for overseeing that sub-adviser's performance. JNAM is solely responsible for payment of any fees to the sub-adviser.

JNAM plays an active role in advising and monitoring each Fund and sub-adviser. When appropriate, JNAM recommends to the Board potential sub-advisers for a Fund. For those Funds managed by a sub-adviser, JNAM monitors each sub-adviser's Fund management team to determine whether its investment activities remain consistent with the Funds' investment strategies and objectives. JNAM also monitors changes that may impact the sub-adviser's overall business, including the sub-adviser's operations and changes in investment personnel and senior management, and regularly performs due diligence reviews of each sub-adviser. In addition, JNAM obtains detailed, comprehensive information concerning each Fund's and sub-adviser's performance and Fund operations. JNAM is responsible for providing regular reports on these matters to the Board.

The Investment Advisory and Management Agreement continues in effect for each Fund from year to year after its initial two-year term so long as its continuation is approved at least annually by (i) a majority of the Trustees who are not parties to such agreement or interested persons of any such party except in their capacity as Trustees of the Trust, and (ii) the shareholders of the affected Fund or the Board. It may be terminated at any time upon 60 days' notice by JNAM, or by a majority vote of the outstanding shares of a Fund with respect to that Fund, and will terminate automatically upon assignment. Additional Funds may be subject to a different agreement. The Investment Advisory and Management Agreement provides that JNAM shall not be liable for any error of judgment, or for any loss suffered by any Fund in connection with the matters to which the agreement relates, except a loss resulting from willful misfeasance, bad faith or gross negligence on the part of JNAM in the performance of its obligations and duties, or by reason of its reckless disregard of its obligations and duties under the agreement. As compensation for its services, the Trust pays JNAM a fee in respect of each Fund as described in each Fund's Prospectus.

Management Fees

As compensation for its advisory services, JNAM receives a fee from the Trust computed separately for the Funds, accrued daily and payable monthly. The fee JNAM receives from each Fund is set forth below as an annual percentage of the net assets of the Fund.

The table below shows the advisory fee rate schedule for each Fund as set forth in the Investment Advisory and Management Agreement and the aggregate annual fee the Fund paid to JNAM for the fiscal year ended December 31, 2024. Each Fund's advisory fee rate schedule is subject to contractual breakpoints that reduce the advisory fee rate should the Fund's average daily net assets exceed specified amounts.

16

JNAM selects, contracts with, and compensates the sub-advisers to manage the investment and reinvestment of the assets of the Funds. JNAM monitors the compliance of the sub-advisers with the investment objectives and related policies of the Funds, reviews the performance of the sub-advisers, and reports periodically on such performance to the Board. Under the terms of each of the sub-advisory agreements, the sub-adviser is responsible for supervising and managing the investment and reinvestment of the assets of the assigned Fund and for directing the purchase and sale of the Fund's investment securities, subject to the oversight and supervision of JNAM and the Board. The sub-advisers formulate a continuous investment program for an assigned Fund consistent with the Fund's investment strategies, objectives and policies outlined in its Prospectus. Each sub-adviser implements such program by purchases and sales of securities and regularly reports to JNAM and the Board with respect to the implementation of such programs. As compensation for its sub-advisory services, each sub-adviser receives a fee from JNAM, computed separately for the applicable Fund, stated as an annual percentage of the Fund's net assets. JNAM currently is obligated to pay the sub-advisers out of the advisory fee it receives from the applicable Fund.

JNAM and the Trust, together with other investment companies of which JNAM is investment adviser, have received an exemptive order (the "Order") that allows JNAM to hire, replace or terminate unaffiliated sub-advisers or materially amend a sub-advisory agreement with an unaffiliated sub-adviser with the approval of the Board, but without the approval of shareholders. However, any amendment to an advisory agreement between JNAM and the Trust that would result in an increase in the management fee rate specified in that agreement (i.e., the aggregate management fee) charged to a Fund will be submitted to shareholders for approval. Under the terms of the Order, if a new sub-adviser is hired by JNAM, the affected Fund will provide shareholders with information about the new sub-adviser and the new sub-advisory agreement within ninety (90) days of the change. The Order allows the Funds to operate more efficiently and with greater flexibility. JNAM provides oversight and evaluation services to the Funds, including, but not limited to the following services: performing initial due diligence on prospective sub-advisers for the Funds; monitoring the performance of sub-advisers; communicating performance expectations to the sub-advisers; and ultimately recommending to the Board whether a sub-adviser's contract should be renewed, modified or terminated.

JNAM does not expect to recommend frequent changes of sub-advisers. Although JNAM will monitor the performance of the sub-advisers, there is no certainty that the sub-advisers or the Funds will obtain favorable results at any given time.

As compensation for the services for their respective Funds, the sub-adviser to the Acquired Fund, AQR, and the sub-adviser to the Acquiring Fund, DFA, each receive a sub-advisory fee that is payable by JNAM.

The following table shows the amount of sub-advisory fees that JNAM paid the sub-advisers (out of JNAM's advisory fees) for the services provided by the respective sub-advisers for the fiscal year ended December 31, 2024:

Fund Aggregate Fees Paid to Sub-Advisers
Dollar Amount As a Percentage of Average Daily Net Assets as of December 31, 2024
AQR Fund $791,032 0.19%
DFA Fund $1,341,921 0.10%

A discussion of the basis for the Board's approval of the sub-advisory agreements is available in the Trust's N-CSR filing for the year ended December 31, 2024 and will be available in the Trust's N-CSR filing for the period ended December 31, 2025.

In addition to the investment advisory fee, each Fund currently pays to JNAM (the "Administrator") an administrative fee as an annual percentage of the average daily net assets of each Fund, accrued daily and paid monthly, as set forth below.

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

In return for the administrative fee, the Administrator provides or procures all necessary administrative functions and services for the operation of each Fund. In addition, the Administrator, at its own expense, arranges and pays for routine legal, audit, fund accounting, custody (except overdraft and interest expense), printing and mailing, a portion of the Chief Compliance Officer costs and all other services necessary for the operation of each Fund. Each Fund is responsible for trading expenses including brokerage commissions, interest and taxes, and other non-operating expenses. Each Fund is also responsible for nonrecurring and extraordinary legal fees, interest expenses, registration fees, licensing costs, directors and officers insurance, expenses related to the Funds' Chief Compliance Officer, and the fees and expenses of the Independent Trustees and of independent legal counsel to the Independent Trustees (categorized as "Other Expenses" in the fee tables).

The Sub-Advisers

The sub-adviser to the Acquired Fund is AQR. AQR is a Delaware limited liability company formed in 1998. AQR provides discretionary investment management services to registered investment companies, collective investment vehicles, private investment partnerships, foreign investment companies and separately managed accounts.

Additional Information

Classes of Shares

The Trust has adopted a multi-class plan pursuant to Rule 18f-3 under the 1940 Act. Under the multi-class plan, the Funds have two classes of shares, Class A and Class I. As discussed in "Distribution Arrangements" below, the Class A shares of the Funds are subject to a Rule 12b-1 fee equal to 0.30% of the Fund's average daily net assets attributable to Class A shares. Class I shares are not subject to a Rule 12b-1 fee. Under the multi-class structure, the Class A shares and Class I shares of the Funds represent interests in the same portfolio of securities and are substantially the same except for "class expenses."

The expenses of the Funds are borne by each class of shares based on the net assets of the Fund attributable to each Class, except that class expenses are allocated to the appropriate class. "Class expenses" include any distribution, administrative or service expense allocable to that class, pursuant to the 12b-1 Plan described below, and any other expenses that JNAM determines, subject to ratification or approval by the Board, to be properly allocable to that class, including: (i) printing and postage expenses related to preparing and distributing to the shareholders of a particular class (or Contract Owners funded by shares of such class) materials such as Prospectuses, shareholder reports and (ii) professional fees relating solely to one class.

Distribution Arrangements

JNLD (or the "Distributor"), 300 Innovation Dr., Franklin, Tennessee 37067 is the principal underwriter of the Funds of the Trust. JNLD is an indirect, wholly owned subsidiary of Jackson. JNLD is responsible for promoting sales of each Fund's shares. The Distributor also is the principal underwriter of the variable annuity insurance products issued by Jackson National and its subsidiaries. On behalf of the Funds, the Trust has adopted, in accordance with the provisions of Rule 12b-1 under the 1940 Act, an Amended and Restated Distribution Plan ("Plan") with respect to the Class A shares of each Fund. The Board, including all of the Independent Trustees, must approve, at least annually, the continuation of the Plan. Under the Plan, each Fund pays a Rule 12b-1 fee to JNLD, as principal underwriter, at an annual rate of 0.30% of the Fund's average daily net assets attributed to Class A shares, as compensation for distribution, administrative or other service activities incurred by JNLD and its affiliates with respect to Class A shares. Class I shares are not subject to a Rule 12b-1 fee. Because these fees are paid out of a Fund's assets on an on-going basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges. To the extent consistent with the Plan and applicable law, the Distributor may use the Rule 12b-1 fee to compensate broker-dealers, administrators, financial intermediaries or others for providing or assisting in providing distribution and related additional services.

19

The Distributor and/or an affiliate have the following relationships with one or more of the sub-advisers and/or their respective affiliates:

The Distributor receives payments from certain of the sub-advisers to assist in defraying the costs of certain promotional and marketing meetings in which those sub-advisers participate. The amounts paid depend on the nature of the meetings, the number of meetings attended, the costs expected to be incurred, and the level of the sub-adviser's participation.
The Distributor acts as distributor of variable insurance contracts and variable life insurance policies issued by the Insurance Companies. The compensation consists of commissions, trail commissions, and other compensation or promotional incentives as described in the Prospectus or statement of additional information for the variable insurance contracts and variable life insurance policies.

Payments to Broker-Dealers and Financial Intermediaries

Only Separate Accounts of the Insurance Companies and series, including fund of funds, of registered investment companies in which either or both of the Insurance Companies invest may purchase shares of the Funds. You may invest indirectly in the Funds through your purchase of a variable annuity or life insurance contract issued by Separate Accounts of the Insurance Companies that invests directly, or through a fund of funds, in these Funds. Any minimum initial or subsequent investment requirements and redemption procedures are governed by the applicable Separate Account through which you invest indirectly. If an investor invests in the Funds 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 Funds and their 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 the salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

Investment in Trust Shares

Shares of the Funds are presently offered only to Separate Accounts of the Insurance Companies to fund the benefits under certain Contracts, to non-qualified retirement plans, other regulated investment companies, other affiliated funds and to Jackson. The Separate Accounts, through their various sub-accounts that invest in designated Funds, purchase the shares of the Funds at their net asset value ("NAV") using premiums received on Contracts issued by the insurance company. Shares of the Funds are not available to the general public for direct purchase.

Purchases are effected at NAV next determined after the purchase order is received by JNAM as the Funds' transfer agent in proper form. There is no sales charge.

The Funds are managed by sub-advisers who manage publicly available mutual funds that have similar names and investment objectives. While the Funds may be similar to or modeled after publicly available mutual funds, Contract Owners should understand that the Funds are not otherwise directly related to any publicly available mutual fund. Consequently, the investment performance of publicly available mutual funds and any corresponding Fund may differ substantially.

The price of each Fund's shares is based on its NAV. The NAV of each Fund's shares is generally determined by JNAM once each day on which the New York Stock Exchange ("NYSE") is open (a "Business Day") at the close of the regular trading session of the NYSE (normally 4:00 p.m. Eastern Time, Monday through Friday). However, consistent with legal requirements, calculation of each Fund's NAV may be suspended on days determined by the Board during times of NYSE market closure, which may include times during which the SEC issues policies or protocols associated with such closure pursuant to Section 22(e) of the 1940 Act. The NAV per share of each Fund is calculated by adding the value of all securities and other assets of a Fund, deducting its liabilities, and dividing by the number of shares outstanding. To the extent circumstances prevent the use of the primary calculation methodology previously described, the Adviser may use alternative methods to calculate the NAV. Generally, the value of exchange-listed or exchange-traded securities is based on their respective market prices, and fixed income securities are valued based on prices provided by an independent pricing service. Current NAV per share of the Fund's classes may be obtained by calling 1-800-644-4565 (Jackson National Customer Care).

20

Domestic fixed-income and foreign securities are normally priced using data reflecting the closing of the principal markets or market participants for those securities, which may be earlier than the NYSE close. Information that becomes known to the Funds or its agents after the NAV has been calculated on a particular day will not normally be used to retroactively adjust the price of a security or the NAV determined earlier that day.

The Board, on behalf of each Fund, has designated to the Adviser the responsibility for carrying out certain functions relating to the valuation of portfolio securities for the purpose of determining the NAV of each Fund. Further, the Board has designated JNAM as the Valuation Designee. As the Valuation Designee, the Adviser has established a valuation committee and adopted procedures and guidelines pursuant to which JNAM determines the "fair value" of a security for which market quotations are not readily available or are determined to be not reflective of market value. Under these procedures, the "fair value" of a security generally will be the amount, determined by JNAM in good faith, that the owner of such security might reasonably expect to receive upon its current sale.

JNAM has established a valuation committee to review fair value determinations pursuant to the Trust's "Valuation Policies and Procedures" and "Valuation Guidelines." The valuation committee will also review the value of restricted securities, securities and assets for which a current market price is not readily available, and securities and assets for which there is reason to believe that the most recent market price is not reflective of the market value (e.g. disorderly market transactions). In the event that the NYSE is closed unexpectedly or opens for trading but closes earlier than scheduled, the valuation committee will evaluate if trading activity on other U.S. exchanges and markets for equity securities is considered reflective of normal market activity. To the extent an NYSE closure is determined to be accompanied by a disruption of normal market activity, the valuation committee may utilize the time the NYSE closed for purposes of measuring and calculating the Funds' NAVs. To the extent an NYSE closure is determined to not have resulted in a disruption of normal market activity, the valuation committee may utilize the time the NYSE was scheduled to close for purposes of measuring and calculating the Funds' NAVs.

The Funds may invest in securities primarily listed on foreign exchanges and that trade on days when the Fund does not price its shares. As a result, a Fund's NAV may change on days when shareholders are not able to purchase or redeem the Fund's shares.

Because the calculation of a Fund's NAV does not take place contemporaneously with the determination of the closing prices of the majority of foreign portfolio securities used in the calculation, there exists a risk that the value of foreign portfolio securities will change after the close of the exchange on which they are traded, but before calculation of the Fund's NAV ("time-zone arbitrage"). Accordingly, the Trust's procedures for valuing of portfolio securities also authorize JNAM to determine the "fair value" of such foreign securities for purposes of calculating a Fund's NAV. When fair valuing foreign equity securities, JNAM adjusts the closing prices of foreign portfolio equity securities based upon pricing models provided by an independent pricing service in order to reflect the "fair value" of such securities for purposes of determining a Fund's NAV. Foreign equity securities traded in North America and South America may be fair valued utilizing international adjustment factors in response to local market holidays, exchange closures, or other events as deemed necessary in order to reflect the "fair value" of such securities for purposes of determining a Fund's NAV. These procedures seek to minimize the opportunities for "time zone arbitrage" in Funds that invest all or substantial portions of their assets in foreign securities, thereby seeking to make those Funds significantly less attractive to "market timers" and other investors who might seek to profit from time zone arbitrage and seeking to reduce the potential for harm to other Fund investors resulting from such practices. However, these procedures may not completely eliminate opportunities for time zone arbitrage because it is not possible to predict in all circumstances whether post-closing events will have a significant impact on securities prices.

JNAM will "fair value" securities held by a Fund if it determines that a "significant event" has occurred. Under the Trust's valuation procedures, a "significant event" affecting a single issuer might include, but is not limited to, an announcement by the issuer, a competitor, a creditor, a major holder of the issuer's securities, a major customer or supplier, or a governmental, regulatory or self-regulatory authority relating to the issuer, the issuer's products or services, or the issuer's securities, and a "significant event" affecting multiple issuers might include, but is not limited to, a substantial price movement in other securities markets, an announcement by a governmental, regulatory or self-regulatory authority relating to securities markets, political or economic matters, or monetary or credit policies, a natural disaster such as an earthquake, flood or storm, or the outbreak of civil strife or military hostilities.

All investments in the Trust are credited to the shareholder's account in the form of full and fractional shares of the designated Fund (rounded to the nearest 1/1000 of a share). The Trust does not issue share certificates.

21

"Market Timing" Policy

Fund shares may only be purchased by Separate Accounts of the Insurance Companies, the Insurance Companies themselves, non-qualified retirement plans and certain other regulated investment companies.

The interests of a Fund's long-term shareholders may be adversely affected by certain short-term trading activity by other Contract Owners invested in the Separate Accounts. Such short-term trading activity, when excessive, has the potential to, among other things, compromise efficient portfolio management, generate transaction and other costs, and dilute the value of Fund shares held by long-term shareholders. This type of excessive short-term trading activity is referred to herein as "market timing." The Funds are not intended to serve as vehicles for market timing. The Board has adopted policies and procedures with respect to market timing.

The Funds, directly and through its service providers, and the insurance company and qualified retirement plan service providers (collectively, "service providers") take various steps designed to deter and curtail market timing with the cooperation of the Insurance Companies. For example, in the event of a round trip transfer, complete or partial redemptions by a shareholder from a sub-account investing in a Fund is permitted; however, once a complete or partial redemption has been made from a sub-account that invests in a Fund, through a sub-account transfer, shareholders will not be permitted to transfer any value back into that sub-account (and the corresponding Fund) within fifteen (15) calendar days of the redemption. The Funds will treat as short-term trading activity any transfer that is requested into a sub-account that was previously redeemed within the previous fifteen (15) calendar days, whether the transfer was requested by the shareholders or a third party authorized by the shareholder.

In addition to identifying any potentially disruptive trading activity, the Funds' Board has adopted a policy of "fair value" pricing to discourage investors from engaging in market timing or other excessive trading strategies for international Funds. The "fair value" pricing policy applies to all Funds where a significant event (as described above) has occurred. The "fair value" pricing policy is described under "Investment in Trust Shares" above.

The policies and procedures described above are intended to deter and curtail market timing in the Funds. However, there can be no assurance that these policies, together with those of the Insurance Companies, and any other insurance company that may invest in the Funds in the future, will be totally effective in this regard. The Funds rely on the Insurance Companies to take the appropriate steps, including daily monitoring of separate account trading activity, to further deter market timing. If they are ineffective, the adverse consequences described above could occur.

A description of Jackson National's anti-market timing policies and procedures can be found in the appropriate variable insurance contract Prospectus (the "Separate Account Prospectus"). The rights of the Separate Accounts to purchase and redeem shares of a Fund are not affected by any Fund's anti-market timing policies if they are not in violation of the Separate Accounts' anti-market timing policies and procedures.

Share Redemption

A Separate Account redeems shares of a Fund to make benefit or withdrawal payments under the terms of its Contracts. Redemptions typically are processed on any day on which the Trust and the NYSE are open for business and are effected at net asset value next determined after the redemption order is received by JNAM, the Fund's transfer agent, in proper form.

The Trust may suspend the right of redemption only under the following circumstances:

When the NYSE is closed (other than weekends and holidays) or trading is restricted;
When an emergency exists, making disposal of portfolio securities or the valuation of net assets not reasonably practicable; or
During any period when the SEC has by order permitted a suspension of redemption for the protection of shareholders.

The Funds typically expect that a Fund will hold cash or cash equivalents to meet redemption requests. The Funds may also use the proceeds of orders to purchase Fund shares or the proceeds from the sale of portfolio securities to meet redemption requests, if consistent with the management of each Fund. These redemption methods will be used regularly and may also be used in stressed market conditions. The Funds have in place a line of credit intended to provide short-term financing, if necessary, subject to certain conditions, in connection with stressed market conditions or atypical redemption activity. The Funds, pursuant to an exemptive order issued by the SEC and a master Interfund Lending agreement, also have the ability to lend or borrow money for temporary purposes directly to or from one another.

22

In the case of a liquidity event, a Fund's share price and/or returns may be negatively impacted. If a liquidity event occurs, JNAM will notify the Board of the liquidity event and take corrective action. Corrective action may include, among other things, use of the Fund's line of credit or Interfund Lending Program.

Redemptions will generally be in the form of cash, although a Fund reserves the right to redeem in kind from or to another Fund or an unaffiliated fund. If a Fund redeems shares in kind from another Fund or from an unaffiliated fund, it may bear transaction costs and will bear market risks until such time as such securities are converted to cash.

Dividends and Other Distributions

The Funds, which currently qualify and intend to continue to qualify and be eligible for treatment as partnerships for U.S. federal income tax purposes, generally do not expect to make distributions of their net investment income and net realized capital gains.

For each Fund, distributions other than in redemption of Fund shares, if any, are automatically reinvested at net asset value in shares of the distributing class of that Fund.

Tax Status

Each Fund is currently and intends (and the Acquiring Fund intends to continue, following the Closing Date) to be treated as a partnership for U.S. federal income tax purposes, and neither Fund expects to make regular distributions (other than in redemption of Fund Shares) to shareholders. The interests in the Funds are generally owned by one or more Separate Accounts that hold such interests pursuant to Contracts.

Each Fund is treated as a partnership separate from the Trust for purposes of the Code. Therefore, the assets, income, and distributions, if any, of each Fund are considered separately for purposes of determining the tax classification of such Fund.

Because the shareholders of the Funds are Separate Accounts of variable insurance contracts, there are no tax consequences to those shareholders from buying, holding, exchanging and selling shares of the Funds. Distributions from the Funds, if any, are not taxable to those shareholders. However, owners of Contracts should consult the applicable Separate Account Prospectus for more detailed information on tax issues related to the Contracts.

Each Fund currently complies and intends (and the Acquiring Fund intends to continue, following the Closing Date) to comply with the diversification requirements currently imposed by the Code and U.S. Treasury regulations thereunder, on separate accounts of insurance companies as a condition of maintaining the tax-advantaged status of the Contracts issued by Separate Accounts. The Investment Advisory and Management Agreement and sub-advisory agreement require the Funds to be operated in compliance with these diversification requirements. The Adviser and sub-advisers may depart from the investment strategy of a Fund only to the extent necessary to meet these diversification requirements.

FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the financial performance of the Acquired Fund and the Acquiring Fund for the past five years or, if shorter, the period of the Fund's operations. The following tables provide selected per share data for one share of each Fund. The total returns in the financial highlights table represent the rate that an investor would have earned (or lost) on an investment in the Acquired Fund or the Acquiring Fund (assuming reinvestment of all dividends and distributions) held for the entire period. The information does not reflect any charges imposed under a Contract. If charges imposed under a variable contract were reflected, the returns would be lower. You should refer to the appropriate Contract prospectus regarding such charges. Following the Reorganization, the Acquiring Fund will be the accounting and performance survivor.

The annual information below has been derived from financial statements audited by KPMG LLP, an independent registered public accounting firm, and should be read in conjunction with the financial statements and notes thereto, together with the report of KPMG LLP thereon, in the Trust's N-CSR filing. The information for the period ended June 30, 2025 has not been audited. The unaudited interim financial statements as of June 30, 2025 reflect all adjustments which are, in the opinion of management, of a normal recurring nature and necessary for a fair statement of the results for the interim period presented. Each Fund's financial statements are included in the Trust's N-CSR filings, which are available upon request.

VOTING INFORMATION

The following information applies to the Reorganization of the Acquired Fund into the Acquiring Fund for which you are entitled to vote.

The Meeting

The Meeting will be held at 1:30 p.m., Eastern Time, on March 25, 2026, at 1 Corporate Way, Lansing, Michigan 48951, together with any adjournment thereof. The Meeting is being held to consider and vote on the Plan of Reorganization, which provides for the reorganization of the AQR Fund into the DFA Fund, and any other business that may properly come before the Meeting. Only shareholders of the Acquired Fund are entitled to vote on this matter.

A copy of the Plan of Reorganization is attached hereto as Appendix A of this Proxy Statement/Prospectus.

The Board fixed the close of business on January 31, 2026, as the Record Date for the determination of shareholders entitled to notice of, and to vote at, the Meeting or any adjournment thereof.

Quorum and Voting

The Amended and Restated By-Laws of the Trust, dated September 6, 2019 (the "By-Laws"), provide that, except as otherwise provided by law, the Amended and Restated Declaration of Trust dated June 1, 1994 and amended and restated on September 25, 2017 (the "Declaration of Trust"), or the By-Laws, the holders of a majority of the shares issued and outstanding and entitled to vote at the meeting, present in person, present by means of remote communication in a manner, if any, authorized by the Board in its sole discretion, or represented by proxy, shall constitute a quorum for the transaction of business. The presence of the Insurance Companies, through the presence of an authorized representative, constitutes a quorum. A quorum, once established at a meeting, shall not be broken by the withdrawal of enough votes to leave less than a quorum.

The By-Laws further provide that shares may be voted in person or by proxy. A proxy with respect to shares held in the name of two or more persons shall be valid if executed by any one of them unless at or prior to the exercise of the proxy the Trust receives a specific written notice to the contrary from any one of them. A proxy purporting to be executed by or on behalf of a Shareholder shall be deemed valid unless challenged at or prior to its exercise, and the burden of proving its invalidity shall rest on the challenger. At all meetings of Shareholders, unless inspectors of election have been appointed, all questions relating to the qualification of voters and the validity of proxies and the acceptance or rejection of votes shall be decided by the chairman of the meeting. Any person giving voting instructions may revoke them at any time prior to their exercise by submitting to the Secretary of the Trust a superseding voting instruction form or written notice of revocation. Voting instructions can be revoked until the Meeting date. Only the Contract Owner executing the voting instructions can revoke them. The Insurance Companies will vote the shares of the Fund in accordance with all properly executed and unrevoked voting instructions. Unless otherwise specified in the proxy, the proxy shall apply to all shares of the Fund owned by the Shareholder.

Required Vote

The vote of the "majority of the outstanding voting shares" of a Fund is required to approve the Proposal. The vote of the "majority of the outstanding voting shares" means the lesser of (i) 67% or more of the shares of the Fund entitled to vote thereon present in person or by proxy at the Meeting if holders of more than 50% of the outstanding shares of the Fund are present in person or represented by proxy, or (ii) more than 50% of the outstanding shares of the Fund. Except as otherwise provided by law, if a Shareholder abstains from voting as to any matter, then the shares represented by such abstention will be treated as shares that are present at the Meeting for purposes of determining the existence of a quorum. However, abstentions will not be counted as a vote cast on such proposal. The approval of the Proposal depends upon whether a sufficient number of votes are cast for the Proposal. Accordingly, an instruction to abstain from voting on any proposal has the same practical effect as an instruction to vote against the Proposal.

Contract Owner Voting Instructions

The Trust is organized as a Massachusetts business trust. Shares of the Trust currently are sold only to Separate Accounts of the Insurance Companies to fund the benefits of variable insurance contracts, to certain non-qualified employee benefit plans of Jackson National, or directly to the Insurance Companies. In addition, shares of the Trust are sold to certain funds of the Trust organized as funds-of-funds. Although the Insurance Companies legally own all of the shares of the Fund held in their respective Separate Accounts that relate to the Contracts, a portion of the value of each Contract is invested by the Insurance Companies, as provided in the Contract, in shares of one or more funds.

25

Contract Owners have the right under the interpretations of the 1940 Act to instruct the relevant Insurance Company how to vote the shares attributable to their Contract. Contract Owners at the close of business on the Record Date will be entitled to notice of the Meeting and to instruct the relevant Insurance Company how to vote at the Meeting or any adjourned session. The Insurance Company will vote all such shares in accordance with the voting instructions timely given by the Contract Owners with assets invested in the Acquired Fund. Shares for which the Insurance Company receives a voting instruction card that is signed, dated, and timely returned but is not marked to indicate voting instructions will be treated as an instruction to vote the Shares in favor of the Proposal. Shares for which the Insurance Company receives no timely voting instructions from a Contract Owner will be voted by the applicable Insurance Company either for or against approval of the applicable Proposal, or as an abstention, in the same proportion as the Shares for which Contract Owners have provided voting instructions to the Insurance Company. The Insurance Companies and their affiliates will vote their own shares and shares held by other RICs in the same proportion as voting instructions timely given by Contract Owners. As a result, a small number of Contract Owners may determine the outcome of the vote.

Contract Owners may use the enclosed voting instructions form as a ballot to give their voting instructions for those shares attributable to their Contract as of the Record Date. The Insurance Companies have fixed the close of business on March 24, 2026 as the last day on which voting instructions will be accepted, other than those provided in person at the Meeting.

Proxy and Voting Instruction Solicitations

The Board is soliciting proxies from shareholders of the Acquired Fund. The Insurance Companies are the shareholders of record and are soliciting voting instructions from their Contract Owners as to how to vote at the Meeting. In addition to the mailing of these proxy materials, voting instructions may be solicited by letter, telephone or personal contact by officers or employees of the Trust, JNAM or officers or employees of the Insurance Companies.

JNAM, as the Trust's administrator, has retained the services of Broadridge Investor Communication Solutions, Inc. ("Broadridge"), 51 Mercedes Way, Edgewood, New York 11717. Under the agreement between JNAM and Broadridge, Broadridge will provide proxy distribution, solicitation, and tabulation services (the "Services"). The anticipated cost of the Services to be provided by Broadridge in connection with this proxy solicitation is approximately $14,551 and will be borne by JNAM whether or not the Reorganization is consummated.

The costs of printing and mailing of the Notice, this Proxy Statement/Prospectus, and the accompanying voting instruction card, and the solicitation of Contract Owner voting instructions, will be paid by JNAM whether or not the Reorganization is consummated. The Trust does not expect to bear any significant expenses in connection with the Meeting or the solicitation of proxies and voting instructions.

Adjournments

Any authorized voting instructions will be valid for any adjournment of the Meeting. If the Trust receives an insufficient number of votes to approve the Proposal, the Meeting may be adjourned to permit the solicitation of additional votes. The Meeting may be adjourned by the chairperson of the Meeting from time to time to reconvene at the same or some other place as determined by the chairperson of the Meeting for any reason, including failure of a Proposal to receive sufficient votes for approval. No Shareholder vote shall be required for any adjournment. No notice need be given that the Meeting has been adjourned other than by announcement at the Meeting. Any business that might have been transacted at the original Meeting may be transacted at any adjourned Meeting.

Revocation of Voting Instructions

Any person giving voting instructions may revoke them at any time prior to the Meeting by submitting to the Insurance Companies a superseding voting instruction form or written notice of revocation or by appearing and voting in person at the Meeting. Only the Contract Owner executing the voting instructions can revoke them. The Insurance Companies will vote the shares of the Acquired Fund in accordance with all properly executed and un-revoked voting instructions.

Outstanding Shares and Principal Shareholders

The Insurance Companies will vote on the Reorganization as instructed by their Contract Owners. As of January 31, 2026, the Trustees and officers of the Trust, as a group, beneficially owned less than 1% of the outstanding shares of the Acquired Fund.

26

Because the shares of the Funds are sold only to the separate accounts of the Insurance Companies, certain funds of the Trust organized as funds-of-funds, and certain non-qualified retirement plans, the Insurance Companies, through the Separate Accounts which hold shares in the Trust as funding vehicles for the Contracts and certain retirement plans, are the owners of record of substantially all of the shares of the Trust. In addition, Jackson National, through its general account, is the beneficial owner of shares in certain of the Funds, in some cases representing the initial capital contributed at the inception of a Fund, and in other cases representing investments made for other corporate purposes. The table below shows the number of outstanding shares of the Acquired Fund as of the Record Date that are entitled to vote at the Meeting.

Fund Total Number of Outstanding Shares
AQR Fund (Class A) 20,687,962.045
AQR Fund (Class I) 501,385.930

As of the Record Date, January 31, 2026, no person(s) owned 5% or more of the shares of the Acquired Fund either beneficially or of record.

APPENDIX A

PLAN OF REORGANIZATION

JNL SERIES TRUST

JNL/AQR Large Cap Defensive Style Fund

JNL/DFA U.S. Core Equity Fund

This Plan of Reorganization has been entered into on April 24, 2026, by JNL SERIES TRUST (the "Trust"), a Massachusetts business trust, on behalf of its JNL/AQR Large Cap Defensive Style Fund (the "Acquired Fund") and its JNL/DFA U.S. CORE EQUITY FUND (the "Acquiring Fund").

WHEREAS, the Trust is registered with the U.S. Securities and Exchange Commission in accord with the provisions of the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company, and has established several separate series of shares ("funds"), with each fund having its own assets and investment policies;

WHEREAS, the Trust's Board of Trustees, including a majority of the Trustees who are not interested persons of the Trust, has determined that participation in the transaction described herein is in the best interests of the Acquired Fund and the Acquiring Fund, and that the interests of the existing shareholders of the Acquired Fund and the Acquiring Fund will not be diluted as a result of the transaction described herein;

WHEREAS, Article II, Section 2.1 of the Trust's Amended and Restated Declaration of Trust, dated September 25, 2017 (the "Declaration of Trust"), authorizes the Board of Trustees to conduct the business of the Trust and carry on its operations; and

WHEREAS, the Trust's Board of Trustees, including a majority of the Trustees who are not interested persons of the Trust, has approved the reorganization of the Acquired Fund with and into the Acquiring Fund (the "Reorganization"), subject to the approval of the shareholders of the Acquired Fund.

NOW, THEREFORE, all the assets, liabilities, and interests of the Acquired Fund shall be transferred on the Closing Date to the Acquiring Fund, as described below; provided, however, that such transaction shall not occur unless and until this Plan of Reorganization shall have first been approved by a majority of the outstanding voting securities of the Acquired Fund as provided in Section 2(a)(42) of the 1940 Act; and provided further that the Board of Trustees may terminate this Plan of Reorganization at or prior to the Closing Date:

1. The Closing Date shall be April 24, 2026, or if the New York Stock Exchange or another primary trading market for portfolio securities of the Acquired Fund or the Acquiring Fund (each, an "Exchange") is closed to trading or trading thereon is restricted, or trading or the reporting of trading on an Exchange or elsewhere is disrupted so that, in the judgment of the Board of Trustees, accurate appraisal of the value of either the Acquired Fund's or the Acquiring Fund's net assets and/or the net asset value per share of Acquiring Fund shares is impracticable, the Closing Date shall be postponed until the first business day after the day when such trading has been fully resumed and such reporting has been restored;
2. The obligations of the Acquired Fund and the Acquiring Fund to complete the transaction described herein shall be subject to receipt by the Acquired Fund and the Acquiring Fund of an opinion of Ropes & Gray LLP dated on the Closing Date (which opinion will be subject to certain qualifications) satisfactory to both parties substantially to the effect that, for U.S. federal income tax purposes, on the basis of the existing provisions of the Internal Revenue Code of 1986, as amended (the "Code"), Treasury regulations promulgated thereunder, current administrative rules, and court decisions, and assuming, among other assumptions, that the variable annuity contracts or variable life insurance policies funded by insurance company separate accounts that hold shares of the Funds (for purposes of this paragraph, each a "contract" and collectively, the "contracts") and the insurance companies issuing the contracts are properly structured under Subchapter L of the Code, the Reorganization will not be a taxable event for contract owners (the "Tax Opinion"). The Tax Opinion will be based on certain factual certifications made by officers of the Trust, on behalf of each Fund and will also be based on reasonable assumptions. The Tax Opinion may state that it is not a guarantee that the tax consequences of the Reorganization will be as described above, and that there is no assurance that the Internal Revenue Service or a court would agree with the opinion.

A-1

3. On or before the Closing Date, and before effecting the Reorganization described herein, the Trust shall have received a satisfactory written opinion of legal counsel as to such transaction that the securities to be issued in connection with such transaction have been duly authorized and, when issued in accordance with this Plan of Reorganization, will have been validly issued and fully paid and will be non-assessable by the Trust on behalf of the Acquiring Fund.
4. In exchange for all of its shares of the Acquired Fund, each shareholder of such Acquired Fund shall receive a number of shares, including fractional shares, of the corresponding share class of the Acquiring Fund equal in dollar value to the number of whole and fractional shares that such shareholder owns in such Acquired Fund. Each shareholder of such Acquired Fund shall thereupon become a shareholder of the Acquiring Fund.
5. For purposes of this transaction, the value of the shares of the Acquiring Fund and the Acquired Fund shall be determined as of 4:00 p.m., Eastern Time, on the Closing Date. Those valuations shall be made in the usual manner as provided in the relevant prospectus of the Trust.
6. Upon completion of the foregoing transaction (and, notwithstanding anything to the contrary herein, within 24 months of the date hereof), the Acquired Fund shall be terminated and no further shares shall be issued by it. The classes of the Trust's shares representing such Acquired Fund shall thereupon be closed and the shares previously authorized for those classes shall be reclassified by the Board of Trustees. The Trust's Board of Trustees and management of the Trust shall take whatever actions may be necessary under Massachusetts law and the 1940 Act to effect the termination of the Acquired Fund.
7. The costs and expenses associated with the Reorganization relating to the solicitation of proxies, including preparing, filing, printing, and mailing of the proxy statement and related disclosure documents, and the costs and expenses relating to obtaining a consent of an independent registered public accounting firm, will be borne by Jackson National Asset Management, LLC ("JNAM") whether or not the Reorganization is consummated. No sales or other charges will be imposed on contract owners in connection with the Reorganization. The costs and expenses associated with the Reorganization relating to the legal fees, including the legal fees incurred in connection with the analysis under the Code of the tax treatment of this transaction, as well as the costs associated with the preparation of the Tax Opinion, will be borne by the Acquiring Fund whether or not the Reorganization is consummated.

A copy of the Declaration of Trust is on file with the Secretary of the Commonwealth of Massachusetts. Notice is hereby given that this instrument is executed on behalf of the Trustees as Trustees, and is not binding on any of the Trustees, officers, or shareholders of the Trust individually, but only binding on the assets and properties of the Acquired Fund or the Acquiring Fund, respectively.

IN WITNESS WHEREOF, the Trust, on behalf of the Acquired Fund and Acquiring Fund, has caused this Plan of Reorganization to be executed and attested in the City of Chicago, State of Illinois, on the date first written above.

Acquired Fund

JNL/AQR Large Cap Defensive Style Fund

Class A

Class I

Investment Objective. The investment objective of the Fund is to seek total return. Total return consists of capital appreciation and income.

Principal Investment Strategies. The Fund pursues a "defensive" investment style, seeking to provide downside protection with upside potential through active stock selection, risk management, and diversification. The Fund pursues its objective by investing, under normal market conditions, at least 80% of its net assets (including any borrowings for investment purposes) in "Equity Instruments" of large-capitalization issuers. The Fund primarily invests in large-capitalization issuers located in the United States. Equity Instruments include common stock, preferred stock, warrants, exchange-traded funds that invest in equity securities, stock index futures, real estate investment trusts, and other derivative instruments where the reference asset is an equity security. As of the date of this prospectus, AQR Capital Management, LLC, the Fund's sub-adviser ("Sub-Adviser"), generally considers large-cap issuers to be those issuers with market capitalizations within the range of the Morningstar® US Target Market Exposure Index℠ at the time of purchase. As of December 31, 2025 , the market capitalization of the companies comprising the Morningstar US Target Market Exposure Index ranged from $ 11.6 billion to $ 4.5 trillion. The Fund can invest in companies of any size and may invest in small- and mid-cap companies from time to time in the discretion of the Sub-Adviser.

The Fund pursues a defensive investment style, meaning it seeks to participate in rising equity markets while mitigating downside risk in declining markets. In other words, the Fund expects to lag the performance of traditional U.S. equity funds when equity markets are rising but to exceed the performance of traditional U.S. equity funds during equity market declines. To achieve this result, the Fund will be broadly diversified across companies and industries and will invest in companies such that the Sub-Adviser believes will result in a portfolio that exhibits low measures of risk and high quality (e.g., holds stable companies in good business health). The Sub-Adviser believes emphasizing lower risk may result in a portfolio with lower "beta" to markets than an approach that emphasizes higher risk, and thus the Sub-Adviser focuses on investments in companies that are expected to reduce the portfolio's sensitivity to security market fluctuations. The Sub-Adviser expects that the emphasis toward a portfolio with low "beta" and high-quality characteristics may produce higher risk-adjusted returns over a full market cycle than an approach that emphasizes high "beta" or poor-quality.

The Fund is actively managed, and the Sub-Adviser will vary the Fund's exposures to issuers and industries based on the Sub-Adviser's evaluation of investment opportunities. In constructing the portfolio, the Sub-Adviser uses quantitative models, which combine active management to identify quality companies and statistical measures of risk to assure diversification by issuer and industry, as well as additional criteria that form part of the Sub-Adviser's security selection process. The Sub-Adviser uses volatility and correlation forecasting and other portfolio construction methodologies to manage the Fund. The Sub-Adviser utilizes quantitative risk models in furtherance of the Fund's investment objective, which seek to control portfolio level risk. Shifts in allocations among issuers and industries will be determined using the quantitative models based on the Sub-Adviser's determinations of risk and quality, as well as other factors including, but not limited to, managing industry and sector exposures.

The Fund invests significantly in common stocks. The Fund may also invest in or use financial futures contracts as well as exchange-traded funds and similar pooled investment vehicles for hedging purposes, to gain exposure to the equity market and to maintain liquidity to pay for redemptions. The Fund may invest in short-term instruments, including U.S. Government securities, bank certificates of deposit, money market instruments or funds, and such other liquid investments deemed appropriate by the Sub-Adviser. The Fund may invest in these securities without limit for temporary defensive purposes.

There is no assurance that the Fund's use of Equity Instruments providing enhanced exposure will enable the Fund to achieve its investment objective. In addition, to attempt to increase its income or total return, the Fund may lend its portfolio securities to certain types of eligible borrowers.

B-1

The Sub-Adviser utilizes portfolio optimization techniques to determine trading activity, taking into account anticipated transaction costs associated with trading each Equity Instrument. The Fund employs sophisticated proprietary trading techniques in an effort to mitigate trading costs and execution impact on the Fund.

Alongside other factors, the Sub-Adviser may consider environmental, social and governance ("ESG") factors that, depending on the facts and circumstances, are material to the value of an issuer or instrument. Consideration of ESG factors and risks is only one component of the Sub-Adviser's assessment of eligible investments and may not be a determinative factor in the Sub-Adviser's final decision on whether to invest in a security. In addition, the weight given to ESG factors may vary across types of investments, industries, regions and issuers, and ESG factors and weights considered may change over time. The Sub-Adviser may not assess every investment for ESG factors, and, when it does, not every ESG factor may be identified or evaluated.

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 following descriptions of the principal risks do not provide any assurance either of the Fund's investment in any particular type of security, or assurance of the Fund's success in its investment selections, techniques and risk assessments. As a managed portfolio, the Fund may not achieve its investment objective for a variety of reasons including changes in the financial condition of issuers (due to such factors as management performance, reduced demand or overall market changes), fluctuations in the financial markets, declines in overall securities prices, or the Sub-Adviser's investment techniques otherwise failing to achieve the Fund's investment objective. The principal risks of investing in the Fund include:

Equity securities risk
Large-capitalization investing risk
Stock risk
Company risk
Market risk
Managed portfolio risk
Model risk
Volatility risk
Mid-capitalization investing risk
Derivatives risk
Counterparty risk
Forward and futures contract risk
Hedging transactions risk
Leverage risk
Investment in other investment companies risk
Real estate investment risk
REIT investment risk
U.S. Government securities risk

Please see the "Glossary of Risks" section at the end of Appendix B for a description of these risks. There may be other risks that are not listed in this Prospectus that could cause the value of your investment in the Fund to decline and that could prevent the Fund from achieving its stated investment objective. This Prospectus does not describe all of the risks of every technique, investment strategy or temporary defensive position that the Fund may use. For additional information regarding the risks of investing in the Fund, please refer to the Fund's Statement of Additional Information.

Additional Information About the Other Investment Strategies, Other Investments and Risks of the Fund (Other than Principal Strategies/Risks). To effectively manage cash inflows and outflows, the Fund may maintain a cash position primarily consisting of shares of money market mutual funds including the affiliated JNL Government Money Market Fund and investments in other investment companies (such as exchange traded funds) to the extent permitted under the 1940 Act. The Fund may also invest in money market instruments. There may be additional risks that may affect the Fund's ability to achieve its stated investment objective. These additional risks are:

Cybersecurity risk
Investment in money market funds risk
Investment strategy risk

Class I

Investment Objective. The investment objective of the Fund is long-term capital appreciation.

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 securities of U.S. companies. Under normal market conditions, the Fund will invest at least 80% of its assets (net assets plus the amount of any borrowings made for investment purposes) in equity securities of U.S. companies. The Sub-Adviser generally defines a U.S. company as one that is listed and principally traded on a securities exchange in the United States that is deemed appropriate by the Sub-Adviser. The Fund invests in companies of all sizes, with increased exposure to smaller capitalization, lower relative price, and higher profitability companies as compared to their representation in the U.S. Universe. The Sub-Adviser generally defines the U.S. Universe as a market capitalization weighted set (e.g., the larger the company, the greater the proportion of the U.S. Universe it represents.) of U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the Sub-Adviser. Market capitalization weighted means that a company's weighting in the U.S. Universe is proportional to that company's actual market capitalization compared to the total market capitalization of all eligible companies. The higher the company's relative market capitalization, the greater its representation. The Fund's 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 U.S. 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. The Sub-Adviser may also adjust the representation in the Fund of an eligible company, or exclude a company, after considering such factors as free float, price momentum, short run-reversals, trading strategies, liquidity, size, relative price, profitability, investment characteristics, and other factors that the Sub-Adviser determines to be appropriate. The Sub-Adviser may consider a small capitalization company's investment characteristics as compared to other eligible companies when making investment decisions and may exclude a small capitalization company with high recent asset growth. The Fund will generally not exclude more than 5% of the eligible U.S small capitalization company universe based on such investment characteristics. The criteria the Sub-Adviser uses for assessing investment characteristics are subject to change from time to time. The Sub-Adviser may decrease the amount that the Fund invests in eligible small capitalization companies that have lower profitability and/or higher relative prices.

B-3

The percentage allocation of the assets of the Fund to securities of the largest U.S. high relative price companies will generally be reduced from between 2.5% and 25% of their percentage weight in the U.S. Universe. The percentage by which the Fund's allocation to securities of the largest U.S. high relative price companies is reduced will change due to market movements and other factors.

The Fund may purchase or sell futures contracts and options on futures contracts for 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.

The Fund may invest in exchange-traded funds ("ETFs") for the purpose of gaining exposure to the U.S. stock market while maintaining liquidity. In addition to money market instruments and other short-term investments, the Fund may invest in affiliated and unaffiliated registered and unregistered money market funds to manage cash pending investment in other securities or to maintain liquidity for the payment of redemptions or other purposes. Investments in ETFs and money market funds may involve a duplication of certain fees and expenses.

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 following descriptions of the principal risks do not provide any assurance either of the Fund's investment in any particular type of security, or assurance of the Fund's success in its investment selections, techniques and risk assessments. As a managed portfolio, the Fund may not achieve its investment objective for a variety of reasons including changes in the financial condition of issuers (due to such factors as management performance, reduced demand or overall market changes), fluctuations in the financial markets, declines in overall securities prices, or the Sub-Adviser's investment techniques otherwise failing to achieve the Fund's investment objective. The principal risks of investing in the Fund include:

Equity securities risk
Small-capitalization investing risk
Investment style risk
Profitability investment risk
Derivatives risk
Company risk
Managed portfolio risk
Market risk
Stock risk

Please see the "Glossary of Risks" section at the end of Appendix B for a description of these risks. There may be other risks that are not listed in this Prospectus that could cause the value of your investment in the Fund to decline and that could prevent the Fund from achieving its stated investment objective. This Prospectus does not describe all of the risks of every technique, investment strategy or temporary defensive position that the Fund may use. For additional information regarding the risks of investing in the Fund, please refer to the Fund's Statement of Additional Information.

Additional Information About the Other Investment Strategies, Other Investments and Risks of the Fund (Other than Principal Strategies/Risks). In general, securities will not be purchased or sold based on the prospects for the economy, the securities markets or the individual issuers whose shares are eligible for purchase. Securities which have depreciated in value since their acquisition will not be sold solely because prospects for the issuer are not considered attractive or due to an expected or realized decline in securities prices in general. Securities generally will not be sold solely to realize short-term profits, but when circumstances warrant, they may be sold without regard to the length of time held. Securities, including those eligible for purchase, may be disposed of, however, at any time when, in the Sub-Adviser's judgment, circumstances warrant their sale, including but not limited to tender offers, mergers and similar transactions, or bids made for block purchases at opportune prices. Generally, securities will be purchased with the expectation that they will be held for longer than one year and will be held until such time as they are no longer considered an appropriate holding in light of the investment policy of the Fund.

In attempting to respond to adverse market, economic, political, or other conditions, the Fund may, from time to time, invest its assets in a temporary defensive manner that is inconsistent with the Fund's principal investment strategies. In these circumstances, the Fund may be unable to achieve its investment objective.

To effectively manage cash inflows and outflows, the Fund may maintain a cash position primarily consisting of shares of money market mutual funds including the affiliated JNL Government Money Market Fund and investments in other investment companies (such as exchange traded funds) to the extent permitted under the 1940 Act. The Fund may also invest in money market instruments.

Exchange-traded funds investing risk
Expense risk
Investment in other investment companies risk
Investment strategy risk
Redemption risk
Regulatory investment limits risk
Sector risk
Settlement risk
Temporary defensive positions and large cash positions risk

Please see the "Glossary of Risks" section at the end of Appendix B for a description of these risks.

In addition, the performance of the Fund depends on the Sub-Adviser's abilities to effectively implement the investment strategies of the Fund.

The Fund's Statement of Additional Information has more information about the Fund's authorized investments and strategies, as well as the risks and restrictions that may apply to it.

Glossary of Risks

Company risk - Investments in U.S. and 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. The value of the Fund's investment may decrease in response to the activities and financial prospects of an individual foreign or domestic company/issuer in the Fund's portfolio. The value of an individual foreign or domestic company can be more volatile than the market as a whole.

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.

Participants in OTC derivatives markets typically are not subject to the same level of credit evaluation and regulatory oversight as are members of exchange-based markets, and, therefore, OTC derivatives generally expose a Fund to greater counterparty risk than exchange-traded or cleared derivatives. A Fund is subject to the risk that a counterparty will not settle a derivative in accordance with its terms because of a dispute over the terms of the contract (whether or not bona fide) or because of a credit or liquidity problem. If a counterparty's obligation to a Fund is not collateralized, then the Fund is essentially an unsecured creditor of the counterparty. If a counterparty defaults, the Fund will have contractual remedies, but the Fund may be delayed and/or unable to enforce them, which may cause the Fund to suffer a loss. Counterparty risk is greater for derivatives with longer maturities because there is more time for events to occur that may prevent settlement. Counterparty risk also is greater when a Fund has concentrated its derivatives with a single or small group of counterparties. Counterparty risk still exists even if a counterparty's obligations are secured by collateral because, for example, the Fund's interest in the collateral may not be perfected or additional collateral may not be promptly posted as required.

A Fund also is subject to counterparty risk because it executes its securities transactions through brokers and dealers. If a broker or dealer fails to meet its contractual obligations, goes bankrupt, or otherwise experiences a business interruption, the Fund could miss investment opportunities or be unable to dispose of investments it would prefer to sell, resulting in losses for the Fund.

B-5

Counterparty risk with respect to derivatives will be affected by rules and regulations affecting the derivatives market. Some derivatives transactions (including futures, options on futures and certain swaps) are required to be centrally cleared, and a party to a cleared derivatives transaction is subject to the credit risk of the clearing house and the clearing member through which it holds its cleared position, rather than the credit risk of its original counterparty to the derivatives transaction. Credit risk of market participants with respect to derivatives that are centrally cleared is concentrated in a few clearing houses, and it is not clear how an insolvency proceeding of a clearing house would be conducted and what impact an insolvency of a clearing house would have on the financial system. A clearing member is obligated by contract and by applicable regulation to segregate all funds received from customers with respect to cleared derivatives transactions from the clearing member's proprietary assets. However, all funds and other property received by a clearing member from its customers with respect to cleared derivatives are generally held by the clearing member on a commingled basis in an omnibus account, and the clearing member may invest those funds in certain instruments permitted under the applicable regulations. Therefore, a Fund might not be fully protected in the event of the bankruptcy of a Fund's clearing member because the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member's customers for a relevant account class. Also, the clearing member is required to transfer to the clearing house the amount of margin required by the clearing house for cleared derivatives, which amounts are generally held in an omnibus account at the clearing house for all customers of the clearing member. Regulations promulgated by the CFTC require that the clearing member notify the clearing house of the initial margin provided by the clearing member to the clearing house that is attributable to each customer. However, if the clearing member does not accurately report a Fund's initial margin, the Fund is subject to the risk that a clearing house will use the Fund's assets held in an omnibus account at the clearing house to satisfy payment obligations of a defaulting customer of the clearing member to the clearing house. In addition, clearing members generally provide the clearing house the net amount of variation margin required for cleared derivatives for all of its customers in the aggregate, rather than individually for each customer. A Fund is therefore subject to the risk that a clearing house will not make variation margin payments owed to the Fund if another customer of the clearing member has suffered a loss and is in default, and the risk that the Fund will be required to provide additional variation margin to the clearing house before the clearing house will move the Fund's cleared derivatives transactions to another clearing member. In addition, if a clearing member does not comply with the applicable regulations or its agreement with a Fund, or in the event of fraud or misappropriation of customer assets by a clearing member, the Fund could have only an unsecured creditor claim in an insolvency of the clearing member with respect to the margin held by the clearing member.

Also, under special resolution regimes adopted in the United States, the European Union, the United Kingdom and various other jurisdictions, the possibility exists that the Funds' ability to exercise remedies, such as the termination of transactions, netting of obligations and realization on collateral, could be stayed or eliminated in the event of a counterparty's (or its affiliate's) insolvency. Such regimes provide government authorities with broad authority to intervene when a financial institution is experiencing financial difficulty. In particular, governmental authorities could reduce, eliminate, or convert to equity the liabilities to the Funds of a counterparty experiencing financial difficulties (sometimes referred to as a "bail in").

Cybersecurity risk - Cyber attacks could cause business failures or delays in daily processing and the Fund may need to delay transactions, consistent with regulatory requirements, as a result could impact the performance of the Fund. See the "Technology Disruptions" section in this Prospectus.

Derivatives risk - Certain Funds may invest in derivatives, which are financial instruments whose value depends on, or is derived from, the value of underlying assets, reference rates, or indices. Derivatives 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 a number of risks described elsewhere in this section, such as 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.

The Fund's investment manager must choose the correct derivatives exposure versus the underlying assets to be hedged or the income to be generated, in order to realize the desired results from the investment. The Fund's investment manager must also correctly predict price, credit or their applicable movements, during the life of a derivative, with respect to the underlying asset in order to realize the desired results from the investment.

The Fund could experience losses if its derivatives were poorly correlated with its other investments, or if the Fund were unable to liquidate its position because of an illiquid market. The market for many derivatives is, or suddenly can become, illiquid. Changes in liquidity may result in significant, rapid and unpredictable changes in the prices for derivatives. The value of derivatives may fluctuate more rapidly than other investments, which may increase the volatility of the Fund, depending on the nature and extent of the derivatives in the Fund's portfolio.

B-6

If the Fund's investment manager uses derivatives in attempting to manage or "hedge" the overall risk of the portfolio, the strategy might not be successful and the Fund may lose money. To the extent that the Fund is unable to close out a position because of market illiquidity or counterparty default, the Fund may not be able to prevent further losses of value in its derivatives holdings.

The Fund may also be required to take or make delivery of an underlying instrument that the manager would otherwise have attempted to avoid. Investors should bear in mind that, while a Fund may intend to use derivative strategies on a regular basis, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the investment manager elects not to do so due to availability, cost or other factors.

The Fund's use of derivative instruments may involve risks different from, or possibly greater than, the risks associated with investing directly in securities and other more traditional investments. Certain derivative transactions may have a leveraging effect on the Fund. For example, a small investment in a derivative instrument may have a significant impact on the Fund's exposure to interest rates, currency exchange rates or other investments. As a result, a relatively small price movement in a derivative instrument may cause an immediate and substantial loss or gain. The Fund may engage in such transactions regardless of whether the Fund owns the asset, instrument or components of the index underlying the derivative instrument. The Fund may invest a portion of its assets in these types of instruments, which could cause the Fund's investment exposure to exceed the value of its portfolio securities and its investment performance could be affected by securities it does not own.

The U.S. Government has enacted legislation that provides for the regulation of the derivatives market, including clearing, margin, reporting, and registration requirements. The European Union and the United Kingdom (and some other countries) are implementing similar requirements, which will affect a Fund when it enters into a derivatives transaction with a counterparty organized in that country or otherwise subject to that country's derivatives regulations. Because these requirements are relatively new and evolving (and some of the rules are not yet final), their ultimate impact remains unclear. It is possible that government regulation of various types of derivative instruments could potentially limit or completely restrict the ability of a Fund to use these instruments as a part of its investment strategy, increase the costs of using these instruments or make them less effective. Limits or restrictions applicable to the counterparties with which a Fund engages in derivative transactions could also prevent a Fund from using these instruments or affect the pricing or other factors relating to these instruments, or may change availability of certain investments.

The CFTC and certain futures exchanges have established (and continue to evaluate and revise) limits, referred to as "position limits," on the maximum net long or net short positions which any person or entity may hold or control in particular options and futures contracts (and certain related swap positions). Unless an exemption applies, all positions owned or controlled by the same person or entity, even if in different accounts, must be aggregated for purposes of determining whether the applicable position limits have been exceeded and, as a result, the investment manager's trading decisions may have to be modified or positions held by a Fund may have to be liquidated in order to avoid exceeding such limits. Even if the Fund does not intend to exceed applicable position limits, it is possible that different clients managed by the investment manager or its affiliates may be aggregated for this purpose. The modification of investment decisions or the elimination of open positions, if it occurs, may adversely affect the profitability of the Fund. A violation of position limits could also lead to regulatory action materially adverse to a Fund's investment strategy.

Under the Dodd-Frank Act, a Fund also may be subject to additional recordkeeping and reporting requirements. In addition, the tax treatment of certain derivatives, such as certain swaps, is unclear under current law and may be subject to future legislation, regulation or administrative pronouncements issued by the IRS. Other future regulatory developments may also impact a Fund's ability to invest or remain invested in certain derivatives. Legislation or regulation may also change the way in which a Fund itself is regulated. The investment manager cannot predict the effects of any new governmental regulation that may be implemented or the ability of a Fund to use swaps or any other financial derivative product, and there can be no assurance that any new governmental regulation or self-regulatory organization rule will not adversely affect a Fund's ability to achieve its investment objective.

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.

B-7

Exchange-traded funds investing risk - Most exchange-traded funds ("ETFs") are investment companies whose shares are purchased and sold on a securities exchange. Generally, an ETF represents a portfolio of securities designed to track a particular market segment or index. An investment in an ETF generally presents the following risks: (i) the same primary risks as an investment in a conventional mutual 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.

In addition, many ETFs invest in securities included in, or representative of, underlying indexes regardless of investment merit or market trends and, therefore, these ETFs do not change their investment strategies to respond to changes in the economy, which means that an ETF may be particularly susceptible to a general decline in the market segment relating to the relevant index. As with traditional mutual funds, ETFs charge asset-based fees. The Funds will indirectly pay a proportional share of the asset-based fees of the ETFs in which the Funds invest. During periods of market volatility, there may be delays in the pricing of ETFs, and ETF exchange-traded prices may also be subject to volatility, which could cause the Fund to lose money

Expense risk - Fund expenses are subject to a variety of factors, including fluctuations in the Fund's net assets. Accordingly, actual expenses may be greater or less than those indicated in the Fund's Prospectus. For example, to the extent that the Fund's net assets decrease due to market declines or redemptions, the Fund's expenses will increase as a percentage of Fund net assets. During periods of high market volatility, these increases in the Fund's expense ratio could be significant.

Forward and futures contract risk - The successful use of forward and futures contracts draws upon the investment manager's skill and experience with respect to such instruments and are subject to special risks including, but not limited to: (i) 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; (ii) 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; (iii) losses caused by unanticipated market movements, which are potentially unlimited; (iv) the investment manager's inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; (v) the possibility that the counterparty, clearing member or clearinghouse will default in the performance of its obligations; and (vi) 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.

Hedging transactions risk - The Sub-Adviser from time to time employs various hedging techniques. The success of the Fund's hedging strategy will be subject to the Sub-Adviser's ability to correctly assess the degree of correlation between the performance of the instruments used in the hedging strategy and the performance of the investments in the portfolio being hedged. Since the characteristics of many securities change as markets change or time passes, the success of the Fund's hedging strategy will also be subject to the Sub-Adviser's ability to continually recalculate, readjust, and execute hedges in an efficient and timely manner. For a variety of reasons, the Sub-Adviser may not seek to establish a perfect correlation between such hedging instruments and the portfolio holdings being hedged. Such imperfect correlation may prevent the Fund from achieving the intended hedge or expose the Fund to risk of loss. In addition, it is not possible to hedge fully or perfectly against any risk, and hedging entails its own costs (such as trading commissions and fees).

Investment in money market funds risk - Although a money market fund is designed to be a relatively low risk investment, it is not free of risk. An investment in a money market fund is not insured or guaranteed by a Federal Deposit Insurance Corporation or any other government agency. Although such money market funds seek to maintain a net asset value of $1.00 per share, it is possible to lose money by investing in a money market fund. Despite the short maturities and high credit quality of a money market fund's investments, increases in interest rates and deteriorations in the credit quality of the instruments the Fund has purchased may reduce the Fund's yield and can cause the price of a money market security to decrease. In addition, a money market fund is subject to the risk that the value of an investment may be eroded over time by inflation.

B-8

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.

Investment strategy risk - The Sub-Adviser, or if no Sub-Adviser, the investment manager uses the principal investment strategies and other investment strategies to seek to achieve the Fund's investment objective. Investment decisions made in accordance with these investment strategies may not produce the returns expected, and may cause the Fund's shares to decline in value or may cause the Fund to underperform other funds with similar investment objectives.

Investment style risk - The returns from a certain investment style may be lower than the returns from the overall stock market. For example, value funds typically emphasize stocks whose prices are below-average in comparison to earnings and book value, although they may yield above-average dividends. A value stock 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. As another example, growth funds generally focus on stocks of companies believed to have above-average potential for growth in revenue and earnings. 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).

Large-capitalization investing risk - Large-capitalization stocks as a group could fall out of favor with the market, which may cause the Fund to underperform funds that focus on other types of stocks. In addition, larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and consumer preferences. Many larger companies also may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion.

Leverage risk - Certain transactions, such as reverse repurchase agreements, futures, forwards, swaps, or other derivative instruments, include the use of leverage and may cause the Fund to liquidate portfolio positions at disadvantageous times to satisfy its obligations. Leverage, including borrowing, may cause the Fund to be more volatile because leverage tends to exaggerate the effect of any increase or decrease in the value of the Fund's portfolio securities. 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.

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 Fund's manager's investment techniques could fail to achieve the Fund's investment objective or may negatively affect the Fund's investment performance, or legislative, regulatory, or tax developments may affect the investment techniques available to the manager of the Fund. There is no guarantee that the investment objective of the Fund will be achieved.

Market risk - Stock market risk refers to the fact that stock (equity securities) prices typically fluctuate more than the values of other types of securities, typically in response to changes in the particular company's financial condition and factors affecting the market in general. Over time, the stock market tends to move in cycles, with periods when stock prices rise, and periods when stock prices decline. A slower-growth or recessionary economic environment could have an adverse effect on the price of the various stocks held by the Fund. Consequently, a broad-based market drop may also cause a stock's price to fall.

Bond market risk generally refers to credit risk and interest rate risk. Credit risk is the actual or perceived risk that the issuer of the bond will not pay the interest and principal payments when due. Bond value typically declines if the issuer's credit quality deteriorates. Interest rate risk is the risk that interest rates will rise and the value of bonds will fall. A broad-based market drop may also cause a bond's price to fall.

B-9

Portfolio securities may also 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 such as the coronavirus (COVID-19) pandemic, war, terrorism or natural disasters, or due to factors affecting particular industries represented in the securities markets, such as competitive conditions. Changes in the financial condition of a single issuer can impact a market as a whole, and adverse market conditions may be prolonged and may not have the same impact on all types of securities. In addition, the markets may not favor a particular kind of security, including equity securities or bonds. The values of securities may fall due to factors affecting a particular issuer, industry or the securities market as a whole.

The outbreak of COVID 19, a respiratory disease caused by a novel coronavirus, caused volatility, severe market dislocations and liquidity constraints in many markets, including markets for the securities the Fund holds. The transmission of COVID-19 and efforts to contain its spread resulted in travel restrictions and disruptions, closed international borders, enhanced health screenings at ports of entry and elsewhere, disruption of and delays in healthcare service preparation and delivery, quarantines, event and service cancellations or interruptions, disruptions to business operations (including staff furloughs and reductions) and supply chains, and a reduction in consumer and business spending, as well as general economic concern and uncertainty. These disruptions led to instability in the marketplace and overall volatility. The impact of COVID-19, and other infectious illness outbreaks, epidemics or pandemics that may arise in the future, could adversely affect the economies of many nations or the entire global economy, the financial well-being and performance of individual issuers, borrowers and sectors and the health of the markets generally in potentially significant and unforeseen ways. In addition, the impact of infectious illnesses, such as COVID-19, in emerging market countries may be greater due to generally less established healthcare systems. Public health crises may exacerbate other pre-existing political, social and economic risks in certain countries or globally.

Mid-capitalization investing risk - The stocks of mid-capitalization companies can be more volatile and their shares 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.

Model risk - The Sub-Adviser relies heavily on the quantitative models and information and data supplied or made available by third parties ("Models and Data"). Models and Data are used to construct sets of transactions and investments, to provide risk management insights, and to assist in hedging the Fund's investments. Funds that use models bear the risk that the proprietary quantitative models used by the portfolio managers will not be successful in identifying securities that will help the Funds achieve their investment objectives, which may cause a Fund to underperform its benchmark or other funds with a similar investment objective. When Models and Data prove to be incorrect or incomplete, including because data is stale, missing or unavailable, any decisions made in reliance thereon expose the Fund to potential risks. Similarly, any hedging based on faulty Models and Data may prove to be unsuccessful. Some of the models used by the Sub-Adviser for the Fund are predictive in nature. The use of predictive models has inherent risks. Because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend on the accuracy and reliability of the supplied historical data. All models rely on correct data inputs. If incorrect data is entered into even a well-founded model, the resulting information will be incorrect. However, even if data is inputted correctly, "model prices" will often differ substantially from market prices, especially for instruments with complex characteristics, such as derivative instruments. The Fund is unlikely to be successful unless the assumptions underlying the models are realistic and either remain realistic and relevant in the future or are adjusted to account for changes in the overall market environment. If such assumptions are inaccurate or become inaccurate and are not promptly adjusted, it is likely that profitable trading signals will not be generated, and major losses may result. The Sub-Adviser, in its sole discretion, will continue to test, evaluate and add new models, which may result in the modification of existing models from time to time. There can be no assurance that model modifications will enable the Fund to achieve its investment objective.

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.

B-10

Real estate investment risk - Risks of investing in real estate securities include falling property values due to increasing vacancies in rental properties, declining rents resulting from economic, legal, tax, cultural, political or technological developments, lack of liquidity, limited diversification, and sensitivity to certain economic factors such as interest-rate changes and other market conditions. When growth is slowing, demand for property decreases and prices may decline, which could impact the value of real estate investments as well as mortgage-backed securities that may be held by the Fund. Real estate company share prices may drop because of the failure of borrowers to pay their loans and poor management, and residential developers, in particular, could be negatively impacted by falling home prices, slower mortgage origination and rising construction costs. The securities of smaller real estate-related issuers can be more volatile and less liquid than securities of larger issuers and their issuers can have more limited financial resources.

Redemption risk - Large redemption activity could result in the Fund being forced to sell portfolio securities at a loss or before the Adviser or Sub-Adviser would otherwise decide to do so. Large redemption activity in the Fund may also result in increased expense ratios, higher levels of realized capital gains or losses with respect to the Fund's portfolio securities, higher brokerage commissions, and other transaction costs. It could be difficult for a Fund to meet large redemption requests where there is minimal liquidity in the Fund's portfolio securities.

Regulatory investment limits risk - The U.S. "Federal Securities Laws" may limit the amount a Fund may invest in certain securities. These limits may be Fund specific or they may apply to the investment manager. As a result of these regulatory limitations under the Federal Securities Laws and the asset management and financial industry business activities of the investment manager and its affiliates, the investment manager and the Fund may be prohibited from or limited in effecting transactions in certain securities. The investment manager and the Fund may encounter trading limitations or restrictions because of aggregation issues or other regulatory requirements. The Federal Securities Laws may impose position limits on securities held by the Fund, and the Fund may be limited as to which securities it may purchase or sell, as well as the timing of such purchases or sales. These regulatory investment limits may increase a Fund's expenses and may limit a Fund's performance.

REIT investment risk - The risks of investing in REITs include certain risks associated with the direct ownership of real estate and the real estate industry in general. These include risks related to general, regional and local economic conditions; difficulties in valuing and disposing of real estate; fluctuations in interest rates and property tax rates; shifts in zoning laws; environmental regulations and other governmental action; cash flow dependency; increased operating expenses; lack of availability of mortgage funds; losses due to natural disasters; overbuilding; losses due to casualty or condemnation; changes in property values and rental rates; the management skill and creditworthiness of the REIT manager; and other factors. REITs may have limited financial resources, may trade less frequently and in limited volume, may engage in dilutive offerings of securities and may be more volatile than other securities. REIT issuers may also fail to maintain their exemptions from registration under the Investment Company Act of 1940, as amended, or fail to qualify for the "dividends paid deduction" under the Internal Revenue Code of 1986, as amended, which allows REITs to reduce their corporate taxable income for dividends paid to their shareholders.

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 portfolio managers' choice of securities within such sector.

Air transportation sector risk - The air transportation sector can be significantly affected by competition within the industry, domestic and foreign economies, government regulation, labor relations, terrorism, and the price of fuel. Airline deregulation has substantially diminished the government's role in the air transport sector while promoting an increased level of competition. However, regulations and policies of various domestic and foreign governments can still affect the profitability of individual carriers as well as the entire industry.

Business services sector risk- Companies in the business services sector can be significantly affected by competitive pressures, such as technological developments, fixed-rate pricing, and the ability to attract and retain skilled employees. The success of companies that provide business-related services is, in part, subject to continued demand for business services as companies and other organizations seeking alternative, cost-effective means to meet their economic goals.

B-11

Financial services sector risk- An investment in issuers in the financial services sector may be adversely affected by, among other things: (i) changes in the regulatory framework or interest rates that may negatively affect financial service businesses; (ii) exposure of a financial institution to a non-diversified or concentrated loan portfolio; (iii) exposure to financial leverage and/or investments or agreements which, under certain circumstances, may lead to losses, for example sub-prime loans; and (iv) the risk that a market shock or other unexpected market, economic, political, regulatory, or other event might lead to a sudden decline in the values of most or all companies in the financial services sector.

Gold-mining companies sector risk - An investment in issuers in the gold-mining sector may be susceptible to financial, economic, political or market events, as well as government regulation, impacting the gold industry. Fluctuations in the price of gold often dramatically affect the profitability of companies in the gold-mining sector.

Health care sector risk - An investment in issuers in the health care sector may be adversely affected by government regulations and government health care programs and increases or decreases in the cost of medical products and services. Health care companies are heavily dependent on patent protection and the expiration of a patent may adversely affect their profitability. Health care companies are also subject to extensive litigation based on product liability and similar claims. Regulatory approvals are generally required before new drugs and medical devices or procedures may be introduced and before the acquisition of additional facilities by health care providers, all of which may be time consuming and costly with no guarantee that any product will come to market. Health care companies are also subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Health care companies may also be thinly capitalized and susceptible to product obsolescence.

Industrial companies risk - The stock prices of companies in the industrials sector are affected by supply and demand both for their specific products or services and for industrials sector products in general. Companies in the industrial sector maybe adversely affected by changes in government regulation, world events and economic conditions. In addition, these companies are at risk for environmental damage and product liability claims. Companies in this sector could be adversely affected by commodity price volatility, changes in exchange rates, imposition of export or import controls, increase competition, depletion of resources, technological developments and labor relations.

Infrastructure companies sector risk - Securities and instruments of infrastructure companies are more susceptible to adverse economic or regulatory occurrences affecting their industries. Infrastructure companies may be subject to a variety of factors that may adversely affect their business or operations, including high interest costs in connection with capital construction programs, high leverage, costs associated with environmental and other regulations, the effects of economic slowdown, surplus capacity, increased competition from other providers of services, uncertainties concerning the availability of fuel at reasonable prices, the effects of energy conservation policies and other factors. Infrastructure companies may also be affected by or subject to: regulation by various government authorities; government regulation of rates charged to customers; service interruption due to environmental, operational or other mishaps; the imposition of special tariffs and changes in tax laws, regulatory policies and accounting standards; and general changes in market sentiment toward infrastructure and utilities assets. Other factors that may affect the operations of infrastructure-related companies include innovations in technology, significant changes to the number of ultimate end-users of a company's products, increased susceptibility to terrorist acts or political actions, risks of environmental damage due, and general changes in market sentiment toward infrastructure and utilities assets.

Natural resource-related securities risk - An investment in natural resource-related securities may be subject to the risks associated with natural resource investments in addition to the general risk of the stock market. Such investments are more vulnerable to the price movements of natural resources and factors that particularly affect the oil, gas, mining, energy, chemicals, paper, steel or agriculture sectors. Such factors may include price fluctuations caused by real and perceived inflationary trends and political developments, the cost assumed by natural resource companies in complying with environmental and safety regulations, changes in supply of, or demand for, various natural resources, changes in energy prices, the success of exploration projects, changes in commodity prices, and special risks associated with natural or man-made disasters. A Fund that invests primarily in companies with natural resource assets is subject to the risk that it may perform poorly during a downturn in natural resource prices.

B-12

Precious metals-related securities risk - Prices of precious metals and of precious metals-related securities historically have been very volatile. The high volatility of precious metal prices may adversely affect the financial condition of companies involved with precious metals. The production and sale of precious metals by governments or central banks or other larger holders can be affected by various economic, financial, social and political factors, which may be unpredictable and may have a significant impact on the prices of precious metals. Other factors that may affect the prices of precious metals and securities related to them include changes in inflation, the outlook for inflation and changes in industrial and commercial demand for precious metals.

Utilities sector risk- Utility company securities are particularly sensitive to interest rate movements; when interest rates rise, the stock prices of these companies tend to fall. The continually changing regulatory environment, at both the state and federal level, has led to greater competition in the industry and the emergence of non-regulated providers as a significant part of the industry, which may make some companies less profitable. Companies in the utilities industry may: (i) be subject to risks associated with the difficulty of obtaining adequate returns on invested capital in spite of frequent rate increases and of financing large construction programs during periods of inflation; (ii) face restrictions on operations and increased costs due to environmental and safety regulations, including increased fuel costs; (iii) find that existing plants and equipment or products have been rendered obsolete by technical innovations; (iv) confront challenging environmental conditions, including natural or man-made disasters; (v) tackle difficulties of the capital markets in absorbing utility debt and equity securities; (vi) incur risks associated with the operation of nuclear power plants; and (vii) face the effects of energy conservation and other factors affecting the level of demand for services. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. The deregulation of certain utility companies may eliminate restrictions on profits, but may also subject these companies to greater risks of loss. Adverse regulatory changes could prevent or delay utilities from passing along cost increases to customers, which could hinder a utility's ability to meet its obligations to its suppliers. Furthermore, regulatory authorities, which may be subject to political and other pressures, may not grant future rate increases, or may impose accounting or operational policies, any of which could affect a company's profitability and the value of its securities. In addition, federal, state and municipal governmental authorities may review existing construction projects, and impose additional regulations governing the licensing, construction and operation of power plants. Any of these factors could result in a material adverse impact on the Fund's holdings and the performance of the Fund and, to the extent a Fund is concentrated in the utilities sector, any potential material adverse impact may be magnified.

Securities lending risk - The Fund may lend its portfolio securities to brokers, dealers, and other financial institutions provided a number of conditions are satisfied, including that the loan is fully collateralized. When the Fund lends portfolio securities, its investment performance will continue to reflect changes in the value of the securities loaned, and the fund will also receive a fee or interest on the collateral. Securities lending involves the risk of loss or delays in recovery of the loaned security or loss of rights in the collateral if the borrower fails to return the security loaned or becomes insolvent. The Fund will also bear the risk of any decline in value of securities acquired with cash collateral. The Fund may pay lending fees to a party arranging the loan. See the "Lending of Portfolio Securities" section in this Prospectus.

Settlement risk - Settlement risk is the risk that a settlement in a transfer system does not take place as expected. Delayed settlement may affect a Fund's liquidity due to the timing and receipt of the proceeds from the sale of that security. 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.

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. In addition, such securities may be subject to more abrupt or erratic price movements. Securities of such issuers may lack sufficient market liquidity to enable the Fund to effect sales at an advantageous time or without a substantial drop in price. Small-capitalization companies often have limited product lines, narrower markets and more limited managerial and financial resources, or may depend on the expertise of a few people, than larger, more established companies. As a result, their performance can be more volatile and they face greater risk of business failure, which could increase the volatility of the Fund's portfolio. Generally, the smaller the company size, the greater these risks become.

B-13

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.

Temporary defensive positions and large cash positions risk - In anticipation of, or in response to, adverse market or other conditions, or atypical circumstances such as unusually large cash inflows or redemptions, and Sub-Adviser transitions, and/or Fund mergers or rebalances, the Fund may temporarily hold all or a significant portion, without limitation, of its assets in cash, cash equivalents, affiliated and unaffiliated money market funds, or high-quality debt instruments. During periods in which the Fund employs such a temporary defensive strategy or holds large cash positions, it will not be pursuing, and will not achieve, its investment objective. Taking a defensive or large cash position may reduce the potential for appreciation of the portfolio and may affect performance.

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, such as those of the Government National Mortgage Association; (ii) supported by the right of the issuer to borrow from the U.S. Treasury, such as those of the Federal National Mortgage Association ("Fannie Mae"); (iii) supported by the discretionary authority of the U.S. Government to purchase the issuer's obligations, such as those of the former Student Loan Marketing Association; or (iv) supported only by the credit of the issuer, such as those of the Federal Farm Credit Bureau. The maximum potential liability of the issuers of some U.S. Government securities may greatly exceed their current resources, including their legal right to receive support from the U.S. Treasury. It is possible that these issuers will not have the funds to meet their payment obligations in the future.

Although many types of U.S. Government securities may be purchased by the Funds, such as those issued by Fannie Mae, the Federal Home Loan Mortgage Corporation ("Freddie Mac"), the Federal Home Loan Banks, and other entities chartered or sponsored by Acts of Congress, their securities are neither issued nor guaranteed by the U.S. Treasury and, therefore, are not backed by the full faith and credit of the United States. The U.S. Government may choose not to provide financial support to U.S. Government sponsored agencies or instrumentalities if it is not legally obligated to do so, in which case, if the issuer defaulted, the holder of the securities of such issuer might not be able to recover its investment from the U.S. Government. Fannie Mae and Freddie Mac have been operating as going concerns in a conservatorship overseen by the Federal Housing Finance Agency ("FHFA") since 2008, and each remains liable for all of its obligations, including its guarantees, associated with its mortgage-backed securities. The ongoing effect that this conservatorship will continue to have on the entities' debt and equities and on securities guaranteed by the entities is unclear. No assurance can be given that the U.S. Treasury initiatives discussed above with respect to the debt and mortgage-backed securities issued by Fannie Mae and Freddie Mac will be successful. In addition, new accounting standards and future Congressional action may affect the value of Fannie Mae and Freddie Mac debt.

FHFA and the White House have made public statements regarding plans to consider ending the conservatorships of Fannie Mae and Freddie Mac. In the event that Fannie Mae and Freddie Mac are taken out of conservatorship, it is unclear how the capital structure of Fannie Mae and Freddie Mac would be constructed and what effects, if any, there may be on Fannie Mae's and Freddie Mac's creditworthiness and guarantees of certain mortgage-backed securities. Should Fannie Mae's and Freddie Mac's conservatorship end, there could be an adverse impact on the value of their securities, which could cause losses to the Funds.

Volatility risk - The Fund may have investments that appreciate or depreciate significantly in value over short periods of time. This may cause the Fund's net asset value per share to experience significant appreciations or depreciations in value over short periods of time.

SUPPLEMENTAL FINANCIAL INFORMATION

The Reorganization is expected to be effective as of the close of business on April 24, 2026, or on such later date as may be deemed necessary in the judgment of the Board of Trustees (the "Board") of the JNL Series Trust (the "Trust") in accordance with the Plan of Reorganization (the "Closing Date").

Following the Reorganization, the Acquiring Fund will be the accounting and performance survivor.

A table showing the fees of the Acquiring Fund and the Acquired Fund, and the fees and expenses of the Acquiring Fund on a pro forma basis after giving effect to the proposed Reorganization, is included in the section entitled "Comparative Fee and Expense Tables" of the of the Proxy Statement/Prospectus.

The Reorganization will not result in a material change in the Acquired Fund's investment portfolio due to the investment restrictions of the Acquiring Fund. It is currently anticipated that approximately 30% of the Acquired Fund's holdings will be transferred to the Acquiring Fund in connection with the Reorganization and that, prior to the Reorganization, approximately 70% of the Acquired Fund's holdings will be aligned or sold and the resulting proceeds will be invested in accordance with the Acquiring Fund's principal investment strategies. There is no tax impact to Contract Owners as a result of portfolio repositioning. Additionally, the repositioning is not expected to have a material impact on the performance of the Acquired Fund prior to the Reorganization. Following the Reorganization, the Acquired Fund will cease to exist and the Acquired Fund's performance will not be reflected in the performance of the Acquiring Fund. It is not expected that the Acquiring Fund will revise any of its investment policies following the Reorganization to reflect those of the Acquired Fund. As a result, a schedule of investments of the Acquired Fund modified to show the effects of the Reorganization is not required and is not included. Notwithstanding the foregoing, changes may be made to the Acquired Fund's portfolio in advance of the Reorganization and/or the Acquiring Fund's portfolio following the Reorganization.

There are no material differences in accounting policies of the Acquired Fund as compared to those of the Acquiring Fund.

The Reorganization is not expected to be a taxable event for U.S. federal income tax purposes for Contract Owners.

Each Fund currently is and intends to be treated as a partnership for U.S. federal income tax purposes, and neither Fund expects to make regular distributions (other than in redemption of Fund Shares) to shareholders.

If the Reorganization is consummated, the Combined Fund would seek to continue to be treated as a partnership for U.S. federal income tax purposes, if such qualification is in the best interests of shareholders. Partnerships generally are not subject to federal income tax. In addition, the Acquired Fund, intends to qualify for treatment as a partnership for U.S. federal income tax purposes through the Closing Date of the Reorganization.

The Funds generally do not expect to make distributions of their net investment income and net realized capital gains.

For each Fund, distributions other than in redemption of Fund shares, if any, are automatically reinvested at net asset value in shares of the distributing class of that Fund.
