American Century^® Low Volatility ETF - LVOL

Index performance does not represent the fund's performance. It is not possible to invest directly in an index.

This fund is an actively managed ETF that does not seek to replicate the performance of a specified index. To determine whether to buy or sell a security, the portfolio managers consider, among other things, various fund requirements and standards, along with economic conditions, alternative investments, interest rates and various credit metrics. If the portfolio manager considerations are inaccurate or misapplied, the fund's performance may suffer.

There is no assurance that the fund will be less volatile than the market over the long term or for any specified period. The fund’s strategy of constructing a portfolio that realizes lower volatility than the market may not produce the intended result. A security’s volatility can change very quickly, and specific securities in the fund’s portfolio may become more volatile than expected. Additionally, low volatility investments may underperform the equity markets during periods of strong, rising or speculative equity markets.

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 reimbursement. The net expense ratio is the expense ratio after the application of any waivers or reimbursement. This is the actual ratio that investors paid during the fund's most recent fiscal year. Please see the prospectus for more information.
