The Fund maintains an average portfolio duration that is within 40% of the duration of the Bloomberg U.S. Treasury Inflation Protected Securities Index (the benchmark). The Fund may invest up to 20% of its assets in non-investment grade bonds (high yield or junk bonds) or securities of emerging market issuers.

The Fund may also invest up to 20% of its assets in non-dollar denominated securities of non-U.S. issuers, and may invest without limit in U.S. dollar denominated securities of non-U.S. issuers. The Fund may seek to provide exposure to the investment returns of real assets that trade in the commodity markets through investment in commodity-linked derivative instruments and investment vehicles such as exchange-traded funds that exclusively invest in commodities and are designed to provide this exposure without direct investment in physical commodities. The Fund may also gain exposure to commodity markets by investing up to 25% of its total assets in Cayman Inflation Protected Bond Portfolio, Ltd. (the Subsidiary ), a wholly owned subsidiary of the Fund formed in the Cayman Islands, which invests primarily in commodity-related instruments. The Fund also makes investments in residential and commercial mortgage-backed securities and other asset-backed securities. Non-investment grade bonds acquired by the Fund will generally be in the lower rating categories of the major rating agencies (BB or lower by S&P Global Ratings (S&P) or Ba or lower by Moodys Investors Service, Inc. (Moodys)) or will be determined by the management team to be of similar quality. Split rated bonds will be considered to have the higher credit rating. Split rated bonds are bonds that receive different ratings from two or more rating agencies. The Fund may buy or sell options or futures, or enter into credit default swaps and interest rate or foreign currency transactions, including swaps (collectively, commonly known as derivatives). The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as reverse repurchase agreements or dollar rolls). The Fund may engage in active and frequent trading of portfolio securities to achieve its primary investment strategies.
