Any derivatives that provide exposure to the investment focus suggested by the funds name, or to one or more market risk factors associated with the investment focus suggested by the funds name, are counted (as applicable) toward compliance with the funds 80% investment policy. The fund invests in a diversified portfolio of shorter-term investment-grade fixed income securities, including corporate, government, mortgage- and asset-backed securities, municipal securities, money market securities and bank obligations, and securities of foreign issuers. All of the securities purchased by the fund will be rated investment grade (i.e., rated in one of the four highest credit rating categories) at the time of purchase by at least one of the credit rating agencies or, if unrated, deemed by the adviser to be investment-grade quality. The fund will not be required to sell a holding if it is later downgraded to a below investment-grade rating. While the fund may purchase an individual security with an effective maturity of up to five years, under normal conditions the funds dollar-weighted average effective maturity will be 1.5 years or less. The fund may use a variety of derivatives, such as futures, forwards, and swaps for a number of purposes, such as exposure or hedging. Specifically, the fund uses interest rate futures, interest rate future options, credit default swap indexes, and forward currency exchange contracts. Interest rate futures and interest rate future options are used to manage the funds cash flow, exposure to changes in interest rates or to adjust portfolio duration. Credit default swap indexes are primarily used to hedge the portfolios overall credit risk or to efficiently gain exposure to certain sectors or asset classes (such as high yield bonds). Forward currency exchange contracts are typically used to protect the funds non-U.S. dollar-denominated securities from adverse currency movements. Investment decisions generally reflect the portfolio managers outlook for interest rates and the economy, as well as the prices, yields, and credit quality of various securities in which the fund may invest. For example, if interest rates are expected to fall, the fund may purchase securities with longer maturities (to the extent consistent with the funds investment program) in an attempt to seek higher yields and/or capital appreciation. Conversely, if interest rates are expected to rise, the fund may seek securities with shorter maturities. Show less
