The investment seeks to maximize total return consistent with current income. The fund invests at least 80% of its assets in bonds. The investments include corporate, asset-backed, mortgage-backed and U.S. government securities. Although the fund will invest primarily in securities with a minimum rating in the lowest investment grade category at the time of purchase, it may invest up to 20% of its assets in debt securities that are below investment grade, also known as high yield securities or "junk bonds."
