American Century Growth Fund - I Class TWGIX

The fund invests in stocks of companies that the adviser believes will increase in value over time. The portfolio managers use a variety of analytical research tools and techniques to identify the stocks of larger-sized companies that meet their investment criteria. Normally, the fund's portfolio will primarily consist of securities of companies demonstrating business improvement. Although the portfolio managers intend to invest the fund's assets primarily in U.S. securities, the fund may invest in securities of foreign companies when these securities meet the portfolio managers' standards of selection.
