C000004643 Investment Objective and Strategy
JNL/DoubleLine Core Fixed Income Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by JNL Series Trust.
Investment objective
The investment objective of the Fund is to seek to maximize current income and total return.
Principal investment strategy
The Fund seeks to achieve its objective by investing under normal circumstances at least 80% of its assets (net assets plus the amount of any borrowings for investment purposes) in a diversified portfolio of fixed-income instruments of varying maturities, which may be represented by forwards or derivatives such as options, futures contracts, swap agreements, or commodity-linked derivatives. For purposes of satisfying the 80% requirement, the Fund may also invest in derivative instruments that have economic characteristics similar to the fixed-income instruments mentioned above. Fixed-Income instruments include but are not limited to bonds, debt securities and other fixed income and income-producing instruments of any kind issued or guaranteed by governmental or private sector entities, including securities issued or guaranteed by the United States Government, its agencies, instrumentalities or sponsored corporations; corporate obligations (including foreign subordinated or junior subordinated bank debt, including Tier 1 preferred or hybrid bank debt, and Tier 2 debt); mortgage-backed securities; asset-backed securities (ABS); foreign securities (corporate, currencies and government); emerging market securities (corporate, quasi-sovereigns and government); bank loans and assignments; ABS loans and other securities bearing fixed or variable interest rates of any or no maturity.
Such Fixed-Income instruments may be indexed to inflation by certain issuers. In managing the Funds investments, under normal market conditions, the portfolio manager intends to seek to construct an investment portfolio with a weighted average effective duration of no less than two years and no more than eight years, as calculated by DoubleLine Capital LP (DoubleLine). Duration is a measure of the expected life of a fixed-income security that is used to determine the sensitivity of a securitys price to changes in interest rates. DoubleLine may seek to manage the duration of the Funds portfolio through the use of derivative instruments and other investments (including, among others, inverse floaters, futures contracts, U.S. Treasury swaps, interest rate swaps, total return swaps and options, including options on swap agreements).
The Fund incurs costs in implementing duration management strategies, and there can be no assurance that the Fund will engage in duration management strategies or that any duration management strategy employed by the Fund will be successful. The Fund invests primarily in investment grade debt securities, but may invest up to 33 1/3% of its total assets in high-yield securities (junk bonds), bank loans or assignments rated BB+ or lower by Moodys or equivalently rated by S&P Global Ratings, Fitch Inc., Kroll, DBRS, Morningstar, or any other NRSRO, or, if unrated, determined by DoubleLine to be of comparable quality. DoubleLine does not consider the term junk bonds to include mortgage-backed securities or any other ABS, regardless of their credit rating or credit quality. The Fund may invest up to 30% of its total assets in securities or derivatives denominated in foreign currencies, and may invest beyond this limit in U.S.
dollar-denominated securities of foreign issuers. The Fund may invest up to 30% of its total assets in securities and instruments that are economically tied to emerging market countries. An emerging market country is a country that, at the time the Fund invests in the related fixed income instruments, is classified as an emerging or developing economy by any supranational organization such as an institution in the World Bank Group or the United Nations, or an agency thereof, or is considered an emerging market country for purposes of constructing a major emerging market securities index. The Fund may invest all of its assets in derivative instruments, such as options, futures contracts or swap agreements, or in mortgage-backed securities or ABS. The Fund may purchase or sell securities on a when-issued, delayed delivery or forward commitment basis and may engage in short sales.
The Fund may, without limitation, seek to obtain market exposure to the securities in which it primarily invests by entering into a Fund of purchase and sale contracts or by using other investment techniques (such as buybacks or dollar rolls). The total return sought by the Fund consists of income earned on the Funds investments, plus capital appreciation, if any, which generally arises from decreases in interest rates or improving credit fundamentals for a particular sector or security. The Fund may also invest up to 10% of its total assets in preferred stock, convertible securities and other equity related securities. The Fund may invest in other investment companies, including, for example, other open-end or closed-end investment companies, exchange-traded funds (ETFs), and domestic or foreign private investment vehicles, including investment companies sponsored or managed by DoubleLine or its affiliates.
The Fund may invest in securities issued by companies in the financial services sector.
