This fund is designed to provide broad exposure to U.S. investment grade bonds. Reflecting this goal, the fund invests about 30% in corporate bonds and 70% in U.S. government bonds of all maturities (short-, intermediate-, and long-term issues). As with other bond funds, one of the risks of the fund is that increases in interest rates may cause the price of the bonds in the portfolio to decrease—pricing the fund’s NAV lower. Because the fund invests in all segments and maturities of the fixed income market, investors may consider the fund their core bond holding.
