Description

Objective
The fund's investment objective is to provide as high a level of current income as is consistent with the preservation of capital.
Distinguishing Characteristics
Taking a broadly diversified, high-quality approach, this core bond fund has the ability to invest in every sector of the bond market and pursue multiple sources of active return, with a limited percentage of below-investment-grade holdings. This approach may help diversify equity risk in a portfolio. The fund draws on our experience in managing U.S. core bonds since 1973 and a 90-year heritage of investing in U.S. markets.
Types of Investments
Primarily invests in corporate debt securities, U.S. and other government securities, mortgage-related securities and cash.
Holdings Outside the U.S.
May invest in fixed-income securities of corporations and government entities outside the United States.
Portfolio Restrictions
The fund generally invests at least 80% of its assets in bonds, including corporate bonds, U.S. government securities and money market instruments. At least 60% of its assets will be invested in securities rated A3/A- or better at the time of purchase (or unrated but determined by the fund’s investment adviser to be of equivalent quality). It is the fund’s current practice not to invest more than 5% of its assets in debt securities rated Ba1 and BB+ or below.
