The fund may also invest in inflation-protected securities of U.S. issuers, foreign governments, and other foreign issuers. Under normal circumstances, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in inflation-protected securities and other investments with similar economic characteristics. Inflation-protected securities are structured to provide protection against the negative effects of inflation. The value of an inflation-protected securitys principal or the interest income paid on the security is adjusted to track changes in an official inflation measure, usually the Consumer Price Index for all Urban Consumers with respect to domestic issuers. In an effort to reduce interest rate risk and enhance return, the fund may invest up to 20% of its net assets in securities not issued by the U.S. government, its agencies and instrumentalities. These investments may include inflation-linked securities issued by non-U.S. governments and inflation-linked securities issued by corporations. The fund may also invest in securities that pay nominal rates of interest (i.e., pay a rate of interest that is not adjusted for the rate of inflation), including U.S. Treasury and agency securities, non-U.S. government bonds, corporate bonds, asset-backed securities, mortgage-backed securities, high quality, short-term obligations, and repurchase agreements. Any credit or structured securities held by the fund will typically be those that benefit from inflation either by paying a floating rate of interest or by the underlying fundamental correlation to key components of inflation. The fund normally invests primarily in investment-grade debt securities, but may also invest in lower quality debt securities. Investment-grade debt securities carry a rating of at least BBB from Standard & Poors or Fitch or Baa from Moodys or are of comparable quality as determined by the funds sub-adviser. The fund may not invest more than 10% of its net assets in below investment-grade debt securities (commonly referred to as junk bonds). The fund generally seeks to maintain an average portfolio duration that is within 20% of the duration of the Bloomberg U.S. Treasury Inflation Protected Securities Index, an index of inflation-protected securities. As of December 31, 2022, the duration of the index was 6.6 years. Duration is a measure used to determine the sensitivity of a securitys price to changes in interest rates. The longer a securitys duration, the more sensitive it will be to changes in interest rates. The fund may invest in securities of any maturity and securities that are denominated in U.S. dollars and in foreign currencies. The sub-adviser uses both top-down and bottom-up analysis to determine security and duration positions for the fund. Both top-down and bottom-up approaches rely upon the same fundamental, valuation and technical framework for what the sub-adviser considers to be a comprehensive analysis of all factors which affect asset pricing. These factors are jointly determined and are interdependent. Security sales decisions are driven by the same criteria as purchase decisions. The fund may, but is not required to, engage in certain investment strategies involving derivatives, such as options, futures, forward currency contracts and swaps, including, but not limited to, interest rate or foreign currency transactions, total return and credit default swaps. These investment strategies may be employed to either mitigate risk or generate income. The fund may invest in privately issued securities, including those that are normally purchased pursuant to Rule 144A or Regulation S promulgated under the Securities Act of 1933, as amended.
