The fund will invest substantially in securities tied economically to a number of countries outside the United States, and such investments may include securities tied economically to developing countries. Normally, the fund invests substantially in investment-grade bonds (rated Baa3 or better or BBB or better by Nationally Recognized Statistical Rating Organizations designated by the funds investment adviser or unrated but determined to be of equivalent quality by the funds investment adviser). The fund may also invest up to 25% of its assets in lower quality, higher yielding debt securities (rated Ba1 or below and BB+ or below by Nationally Recognized Statistical Rating Organizations designated by the funds investment adviser or unrated but determined to be of equivalent quality by the funds investment adviser). Such securities are sometimes referred to as junk bonds. The total return of the fund will be the result of interest income, changes in the market value of the funds investments and changes in the values of other currencies relative to the U.S. dollar. The fund may invest in forward currency contracts, 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, long-term investment opportunities. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities. Show less
