The fund maintains a portfolio of bonds, other debt securities and money market instruments having a dollar-weighted average effective maturity of no less than three years and no greater than five years under normal market conditions. The fund invests primarily in bonds and other debt securities with quality ratings of A or better or A3 or better (by a Nationally Recognized Statistical Rating Organization designated by the funds investment adviser) or unrated but determined to be of equivalent quality by the funds investment adviser. The fund may invest up to 10% of its assets in bonds and other debt securities rated in the BBB or Baa rating category (by a Nationally Recognized Statistical Rating Organization designated by the funds investment adviser) or unrated but determined to be of equivalent quality by the funds investment adviser. The fund primarily invests in debt securities denominated in U.S. dollars. These include securities issued and guaranteed by the U.S. government, debt securities and mortgage-backed securities issued by government-sponsored entities and federal agencies, and instrumentalities that are not backed by the full faith and credit of the U.S. government. In addition, the fund may invest in mortgage-backed securities issued by private issuers and asset-backed securities (securities backed by assets such as auto loans, credit card receivables or other providers of credit). The fund may invest in inflation-linked bonds issued by U.S. and non-U.S. governments, their agencies or instrumentalities, and corporations. Inflation-linked bonds are structured to protect against inflation by linking the bonds principal and interest payments to an inflation index, such as the Consumer Price Index for Urban Consumers, so that principal and interest adjust to reflect changes in the index. The fund may also invest in futures contracts and swaps, which are types of derivatives. A derivative is a financial contract, the value of which is based on the value of an underlying financial asset (such as a stock, bond or currency), a reference rate or a market index. The investment adviser uses a system of multiple portfolio managers in managing the funds assets. Under this approach, the portfolio of the fund is divided into segments managed by individual managers. The fund relies on the professional judgment of its investment adviser to make decisions about the funds portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively priced securities that, in its opinion, represent good investment opportunities. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities. Show less
