The portfolio managers draw on growth, value and quantitative investment techniques in managing the equity portion of the funds portfolio, and they diversify the funds equity investments among small, medium and large companies. The fund also invests in a variety of debt securities payable in U.S. and foreign currencies. The fixed-income portion of the fund primarily invests in investment-grade debt securities. An investment-grade security is one that has been rated by at least one independent rating agency in its top four credit quality categories or determined by the advisor to be of comparable credit quality. However, the fund may invest up to 10% of its assets in below investment-grade securities (also known as high-yield securities or junk bonds). The fund may also invest in bank loans and collateralized debt obligations (including collateralized loan obligations). To gain exposure to certain investment disciplines and categories, the fund may invest in varying combinations of affiliated investment companies (mutual funds and exchange-traded funds (ETFs) advised by American Century). The fund also may invest in derivative instruments such as options, futures contracts, options on futures contracts, and swap agreements (including, but not limited to, credit default swap agreements), provided that such investments are in keeping with the funds investment objective. Responsibility for research, stock selection and portfolio construction for other portions of the fund has been allocated among portfolio teams representing various investment disciplines and strategies employed by other American Century funds.
