Class A

Before you invest, you may want to review the Fund's Prospectus, which contains more information about the Fund and its risks. You can find the Fund's Prospectus and other information about the Fund, including the Statement of Additional Information ("SAI") and most recent reports to shareholders, online at http://hosted.rightprospectus.com/Jackson/JNLSeriesTrust. You can also get this information at no cost by calling 1-800-644-4565 (Annuity and Life Service Center), 1-800-599-5651 (NY Annuity and Life Service Center), 1-800-777-7779 (for contracts purchased through a bank or financial institution) or 1-888-464-7779 (for NY contracts purchased through a bank or financial institution), or by sending an email request to ProspectusRequest@jackson.com. The current Prospectus and SAI, both dated April 24, 2017, are incorporated by reference into (which means they legally are a part of) this Summary Prospectus.

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

Expenses. This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund.

The expenses do not reflect the expenses of the variable insurance contracts or the separate account through which you indirectly invest in the Fund, whichever may be applicable and the total expenses would be higher if they were included.

Shareholder Fees

(fees paid directly from your investment)

Not Applicable

Annual Fund Operating Expenses (Expenses that you pay each year as a percentage of the value of your investment)
	Class A
Management Fee	0.30%
Distribution and/or Service (12b-1) Fees	0.20%
Other Expenses¹	0.15%
Acquired Fund Fees and Expenses²	0.26%
Total Annual Fund Operating Expenses	0.91%

¹ "Other Expenses" include an Administrative Fee of 0.15% which is payable to Jackson National Asset Management, LLC ("JNAM" or "Adviser") and are based on estimated amounts for the current fiscal year.

² Acquired Fund Fees and Expenses are the indirect expenses of investing in other investment companies. Accordingly, the expense ratio presented in the Financial Highlights section of the prospectus will not correlate to the Total Annual Operating Expenses disclosed above.

Expense Example. This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. Also, this example does not reflect the expenses of the variable insurance contracts or the separate account through which you indirectly invest in the Fund, whichever may be applicable, and the total expenses would be higher if they were included. The table below shows the expenses you would pay on a $10,000 investment, assuming (1) 5% annual return and (2) redemption at the end of each time period. The example also assumes that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Class A
1 year	3 years
$93	$290

Portfolio Turnover (% of average value of portfolio). The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in Annual Fund Operating Expenses or in the Expense Example above, affect the Fund's performance. The Fund does not have a portfolio turnover rate as of the date of this Prospectus as it commenced operations on the date of this Prospectus.

Principal Investment Strategies. The Fund seeks to achieve its objective by investing in shares of a diversified group of other Funds ("Underlying Funds"). The Underlying Funds in which the Fund may invest are a part of DFA Investment Dimensions Group, Inc. and Dimensional Investment Group Inc. (collectively, "DFA Fund Groups"). Not all Funds of DFA Fund Groups are available as Underlying Funds. Please refer to the statutory prospectus for a list of available Underlying Funds.

To achieve its investment objective, the Fund under normal market circumstances, allocates its assets to Underlying Funds that invest in equity and fixed-income securities. Generally, the Fund invests its assets in domestic and international equity Underlying Funds and fixed-income Underlying Funds to achieve an allocation of approximately 40% to 80% (with a target allocation of approximately 60%) of the Fund's assets to domestic and international equity Underlying Funds and 20% to 60% (with a target allocation of approximately 40%) of its assets to fixed-income Underlying Funds. The equity and fixed-income allocation may fall outside of the above limits in a volatile market environment where investment outcomes are expected to remain beyond normal range.

Within these asset classes, the Fund remains flexible with respect to the percentage it will allocate among Underlying Funds. In determining allocations to any particular Underlying Fund, the Fund's investment adviser considers, among other things, long-term market and economic conditions, historical performance of each Underlying Fund, and expected long-term performance of each Underlying Fund, as well as diversification to control overall portfolio risk exposure.

In addition to its allocation strategy of providing exposure to the domestic and international equity and fixed-income markets through investment in the Underlying Funds, the Fund further diversifies its investment portfolio by allocating its assets among Underlying Funds that represent a variety of different asset classes. As of the dated of this prospectus, the Fund invests in: (1) domestic equity Underlying Funds that purchase a broad and diverse portfolio of securities of U.S. operating companies of all market capitalization sizes with an emphasis on small and value companies, and a domestic equity Underlying Fund that primarily invests in publicly traded REITs; (2) international equity Underlying Funds that purchase a broad and diverse portfolio of securities of companies in developed and emerging markets of all market capitalization sizes with an emphasis on small and value companies; and (3) fixed-income Underlying Funds that may purchase U.S. and foreign debt securities such as obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, bank obligations, commercial paper, repurchase agreements, obligations of other domestic and foreign issuers, securities of domestic and foreign issuers denominated in U.S. dollars but not trading in the United States, obligations of supranational organizations and inflation-protected securities.

The Fund and each Underlying Fund may use derivatives, such as futures contracts and options on futures contracts, to adjust market exposure based on actual or expected cash inflows to or outflows from the Fund or Underlying Fund. Certain fixed-income Underlying Funds use foreign currency contracts to hedge foreign currency risks, hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another. Certain fixed-income Underlying Funds also may enter into credit default swaps on issuers or indices to buy or sell credit protection to hedge its credit exposure; gain market or issuer exposure without owning the underlying securities; or increase the Underlying Fund's total return. Certain fixed-income Underlying Funds also may use derivatives, such as futures contracts and options on futures contracts, to hedge interest rate or currency exposure or for non-hedging purposes, such as a substitute for direct investment. Also, the Underlying Funds may lend their portfolio securities to generate additional income.

Some of the Underlying Funds, particularly those classified as fixed income, may hold a significant amount of junk bonds in order to execute their investment strategy.

The Adviser may change the Underlying Funds in which the Fund invests from time to time at its discretion without notice or shareholder approval. Therefore, the Fund may invest in Underlying Funds that are not listed in the statutory prospectus.

The Fund is a "non-diversified" fund, as defined in the Investment Company Act of 1940, as amended (the "1940 Act"), and may invest more of its assets in fewer issuers than "diversified" mutual funds.

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 Fund will incur the risks associated with each Underlying Fund, including:

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

Concentration risk – To the extent that the Fund focuses on particular countries, regions, industries, sectors, issuers, types of investment or limited number of securities from time to time, the Fund may be subject to greater risks of adverse economic, business or political developments than a fund that invests in a wider variety of countries, regions, industries, sectors or investments.

Credit risk – The price of a debt instrument can decline in response to changes in the financial condition of the issuer, borrower, guarantor, counterparty, or other entity responsible for payment. The Fund could lose money if the issuer or guarantor of a fixed-income security, or the counterparty to a derivatives contract, repurchase agreement or a loan of portfolio securities, is unable or unwilling to make timely principal and/or interest payments, or to otherwise honor its obligations.

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

Derivatives risk – Investments in derivatives, which are financial instruments whose value depends on, or is derived from, the value of underlying assets, reference rates, or indices, can be highly volatile and may be subject to transaction costs and certain risks, such as unanticipated changes in securities prices and global currency investment. Derivatives also are subject to leverage risk, liquidity risk, interest rate risk, market risk, counterparty risk, and credit risk. They also involve the risk of mispricing or improper valuation and the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, interest rate or index. Gains or losses from derivatives can be substantially greater than the derivatives' original cost. Certain derivatives transactions may be subject to counterparty risk.

Emerging markets and less developed countries risk – Emerging market and less developed countries generally are located in Asia, the Middle East, Eastern Europe, Central and South America and Africa. Investments in, or exposure to, securities that are tied economically to emerging market and less developed countries are subject to all of the risks of investments in, or exposure to, foreign securities, generally to a greater extent than in developed markets, among other risks. Investments in securities that are tied economically to emerging markets involve greater risk from economic and political systems that typically are less developed, and likely to be less stable, than those in more advanced countries. The Fund also will be subject to the risk of adverse foreign currency rate fluctuations. Emerging market and less developed countries may also have economies that are predominantly based on only a few industries or dependent on revenues from particular commodities. The risks of nationalization, expropriation or other confiscation of assets of non-U.S. issuers is also greater in emerging and less developed countries. As a result of these risks, investments in securities tied economically to emerging markets tend to be more volatile than investments in securities of developed countries.

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 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.

Fixed-income risk – The price of fixed-income securities responds to economic developments, particularly interest rate changes, as well as to perceptions about the credit risk of individual issuers. Rising interest rates generally will cause the price of bonds and other fixed-income debt securities to fall. Falling interest rates may cause an issuer to redeem, call or refinance a security before its stated maturity, which may result in the Fund having to reinvest the proceeds in lower yielding securities. Bonds and other fixed-income debt securities are subject to credit risk, which is the possibility that the credit strength of an issuer will weaken and/or an issuer of a fixed-income security will fail to make timely payments of principal or interest and the security will go into default.

Foreign regulatory risk – The Adviser is an indirect wholly-owned subsidiary of Prudential plc, a publicly-traded company incorporated in the United Kingdom and is not affiliated in any manner with Prudential Financial Inc., a company whose principal place of business is in the United States of America. Through its ownership structure, the Adviser has a number of global financial industry affiliates. As a result of this structure, and the asset management and financial industry business activities of the Adviser and its affiliates, the Adviser and the Fund may be prohibited or limited in effecting transactions in certain securities. Additionally, the Adviser and the Fund may encounter trading limitations or restrictions because of aggregation issues or other foreign regulatory requirements. Foreign regulators or foreign 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 foreign regulatory limits may increase the Fund's expenses and may limit the Fund's performance.

Foreign securities risk – Investments in, or exposure to, foreign securities involve risks not typically associated with U.S. investments. These risks include, among others, adverse fluctuations in foreign currency values, possible imposition of foreign withholding or other taxes on income payable on the securities, as well as adverse political, social and economic developments, such as political upheaval, acts of terrorism, financial troubles, or natural disasters. Many foreign securities markets, especially those in emerging market countries, are less stable, smaller, less liquid, and less regulated than U.S. securities markets, and the costs of trading in those markets is often higher than in U.S. securities markets. There may also be less publicly-available information about issuers of foreign securities compared to issuers of U.S. securities. In addition, the economies of certain foreign markets may not compare favorably with the economy of the United States with respect to issues such as growth of gross national product, reinvestment of capital, resources and balance of payments position.

High yield bonds, lower-rated bonds, and unrated securities risk – High-yield bonds, lower-rated bonds, and unrated securities are broadly referred to as "junk bonds," and are considered below "investment-grade" by national ratings agencies. Junk bonds are subject to the increased risk of an issuer's inability to meet principal and interest payment obligations. High-yield bonds may be subject to liquidity risk, and the Fund may not be able to sell a high-yield bond at the price at which it is currently valued.

Income risk – The Fund is subject to the risk that the income generated from the Fund's investments may decline in the event of falling interest rates. Income risk may be high if the Fund's income is predominantly based on short-term interest rates, which can fluctuate significantly over short periods. The Fund's distributions to shareholders may decline when interest rates fall.

Interest rate risk – When interest rates increase, fixed-income securities generally will decline in value. Long-term fixed-income securities normally have more price volatility than short-term fixed-income securities. The value of certain equity investments, such as utilities and real estate-related securities, may also be sensitive to interest rate changes.

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

Liquidity risk – Investments in securities that are difficult to purchase or sell (illiquid or thinly-traded securities) may reduce returns if the Fund is unable to sell the securities at an advantageous time or price or achieve its desired level of exposure to a certain sector. Liquidity risk arises, for example, from small average trading volumes, trading restrictions, or temporary suspensions of trading. To meet redemption requests, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

Market risk – Portfolio securities may decline in value due to factors affecting securities markets generally, such as real or perceived adverse economic, political, or regulatory conditions, inflation, changes in interest or currency rates or adverse investor sentiment, among others. Adverse market conditions may be prolonged and may not have the same impact on all types of securities. The values of securities may fall due to factors affecting a particular issuer, industry or the securities market as a whole.

Mortgage-related and other asset-backed securities risk – Rising interest rates tend to extend the duration of mortgage-related and other asset-backed securities, making them more sensitive to changes in interest rates and exhibit increased volatility. When interest rates decline, borrowers may pay off their mortgages or other loans sooner than expected, which can reduce the returns.

Non-diversification risk – The Fund is non-diversified, as defined by the 1940 Act, and as such may invest in the securities of a limited number of issuers and may invest a greater percentage of its assets in a particular issuer. Therefore, a decline in the market price of a particular security held by the Fund may affect the Fund's performance more than if the Fund were a diversified investment company.

Real estate investment risk – Real estate is affected by general economic conditions and legal, cultural or technological developments. When growth is slowing, demand for property decreases and prices may decline. Real estate company share prices may drop because of the failure of borrowers to pay their loans and poor management.

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.

·	Underlying funds risk – The ability of the Fund to achieve its investment objective will depend in part upon the allocations of investments in the Underlying Funds and their ability to achieve their investment objectives.

Performance. Performance for the Fund has not been included because the Fund has not yet commenced operations. Performance, which provides some indication of the risks of investing in the Fund, will be available once the Fund has completed one full calendar year of operations.
