How to Buy

The advisor has agreed to waive the G Class's management fee in its entirety. The advisor expects this fee waiver to remain in effect permanently and cannot terminate it without the approval of the Board of Directors.

The value and/or returns of a portfolio will fluctuate with market and economic conditions.

Different investment styles tend to shift in and out of favor depending upon market and economic conditions, as well as investor sentiment. A fund may outperform or underperform other funds that employ a different investment style.

Although the fund's performance has historically benefited from investments in initial public offerings (IPOs), future IPO exposure likely will be limited by the fund's investment process.

International investing involves special risk considerations, including economic and political conditions, inflation rates and currency fluctuations.

Please see the prospectus for details about sales charges.

The gross expense ratio is the fund's total annual operating costs, expressed as a percentage of the fund's average net assets for a given time period. It is gross of any fee waivers or expense reimbursem*nt. The net expense ratio is the expense ratio after the application of any waivers or reimbursem*nt. This is the actual ratio that investors paid during the fund's most recent fiscal year. Please see the prospectus for more information.

Investor Class Shares: Minimum initial investment is $1,000 for IRA and CESA accounts, and $2,500 for non-retirement accounts, but these minimums are waived with an initial investment of at least $500 per account and automatic investments of at least $100 per month. Non-Retirement Accounts: If your account balance falls below the minimum, or if you cancel your automatic monthly investment plan prior to reaching the minimum, American Century Investments may redeem the account and send the proceeds to you. Prior to doing so, we will notify you and give you 90 days to meet the minimum or reinstate your automatic monthly investment plan.

Sustainability

Many of American Century's investment strategies incorporate the consideration of environmental, social, and/or governance (ESG) factors into their investment processes in addition to traditional financial analysis. However, when doing so, the portfolio managers may not consider ESG factors with respect to every investment decision and, even when such factors are considered, they may conclude that other attributes of an investment outweigh ESG considerations when making decisions for the portfolio. The consideration of ESG factors may limit the investment opportunities available to a portfolio, and the portfolio may perform differently than those that do not incorporate ESG considerations. ESG data used by the portfolio managers often lacks standardization, consistency, and transparency, and for certain companies such data may not be available, complete, or accurate.

ESG Definitions:

• ESG Integrated: An investment strategy that integrates ESG factors aims to make investment decisions through the analysis of ESG factors alongside other financial variables in an effort to deliver superior, long-term, risk-adjusted returns. Therefore, ESG factors may limit the investment opportunities available, and the portfolio may perform differently than those that do not incorporate ESG factors. Portfolio managers have ultimate discretion in how ESG issues may impact a portfolio's holdings, and depending on their analysis, investment decisions may not be affected by ESG factors.

• ESG Focused: An investment strategy that focuses on ESG factors seeks to invest, under normal market conditions, in securities that meet certain ESG criteria or standards in an effort to promote sustainable characteristics, in addition to seeking superior, long-term, risk-adjusted returns. This investment focus may limit the investment opportunities available to a portfolio. Therefore, the portfolio may underperform or perform differently than other portfolios that do not have an ESG investment focus. ESG-focused investment strategies include but are not limited to impact, best-in-class, positive screening, exclusionary, and thematic approaches.
