American Century Short Duration Strategic Income

Fund seeks income. As a secondary objective, the fund seeks long-term capital appreciation. The fund invests in both investment-grade and high-yield, short duration debt securities. These securities may include corporate bonds and notes, government securities and securities backed by mortgages or other assets. Investment grade securities are those that have been rated in one of the top four credit quality categories by an independent rating agency or determined by the advisor to be of comparable credit quality. High-yield securities, which are also known as junk bonds, are those that have been rated by an independent rating agency below the highest four categories or determined by the advisor to be of similar quality.
