This fund is different from traditional ETFs.
Traditional ETFs tell the public what assets they hold each day. This fund will not. This may create additional risks for your investment. For example:
You may have to pay more money to trade the fund's shares. This fund will provide less information to traders, who tend to charge more for trades when they have less information.
The price you pay to buy fund shares on an exchange may not match the value of the fund's portfolio. The same is true when you sell shares. These price differences may be greater for this fund compared to other ETFs because it provides less information to traders.
These additional risks may be even greater in bad or uncertain market conditions.
The ETF will publish on its website each day a "Proxy Portfolio" designed to help trading in shares of the ETF. While the Proxy Portfolio includes some of the ETF's holdings, it is not the ETF's actual portfolio.
The differences between this fund and other ETFs may also have advantages. By keeping certain information about the fund secret, this fund may face less risk that other traders can predict or copy its investment strategy. This may improve the fund's performance. If other traders are able to copy or predict the fund's investment strategy, however, this may hurt the fund's performance.
For additional information regarding the unique attributes and risks of this ETF, see the additional risk discussion at the end of this material.
Index performance does not represent the fund's performance. It is not possible to invest directly in an index.
Exchange Traded Funds (ETFs) are bought and sold through exchange trading at market price (not NAV), and are not individually redeemed from the fund. Shares may trade at a premium or discount to their NAV in the secondary market. Brokerage commissions will reduce returns.
Investment return and principal value of security investments will fluctuate. The value at the time of redemption may be more or less than the original cost. Past performance is no guarantee of future results.
The fund is an actively managed ETF that does not seek to replicate the performance of a specified index.
Proxy Portfolio Risk: The goal of the Proxy Portfolio is to track closely the daily performance of the Actual Portfolio. The Proxy Portfolio is designed to reflect the economic exposures and the risk characteristics of the Actual Portfolio on any given trading day.
ETFs trading on the basis of a published Proxy Portfolio may exhibit wider premiums and discounts, bid/ask spreads, and tracking error than other ETFs using the same investment strategies that publish their portfolios on a daily basis, especially during periods of market disruption or volatility. Therefore, shares of the fund may cost investors more to trade than shares of a traditional ETF.
Each day the fund calculates the overlap between the holdings of the prior Business Day's Proxy Portfolio compared to the Actual Portfolio (Proxy Overlap) and the difference, in percentage terms, between the Proxy Portfolio per share NAV and that of the Actual Portfolio (Tracking Error).
Although the fund seeks to benefit from keeping its portfolio information secret, market participants may attempt to use the Proxy Portfolio to identify a fund's trading strategy, which if successful, could result in such market participants engaging in certain predatory trading practices that may have the potential to harm the fund and its shareholders.
Premium/Discount Risk: Although the Proxy Portfolio is intended to provide investors with enough information to allow for an effective arbitrage mechanism that will keep the market price of the fund at or close to the underlying net asset value (NAV) per share of the fund, there is a risk (which may increase during periods of market disruption or volatility) that market prices will vary significantly from the underlying NAV of the fund.
Trading Issues Risk: Trading halts may have a greater impact on this fund compared to other ETFs due to the fund's nontransparent structure.
Authorized Participant Concentration Risk: Only an authorized participant may engage in creation or redemption transactions directly with the fund. The fund may have a limited number of institutions that act as authorized participants. The fact that the fund is offering a novel and unique structure may affect the number of entities willing to act as Authorized Participants. During times of market stress, Authorized Participants may be more likely to step away from this type of ETF than a traditional ETF.
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.
MID is classified as non-diversified. Because it is non-diversified, it may hold large positions in a small number of securities. To the extent it maintains such positions; a price change in any one of those securities may have a greater impact on the fund's share price than if it were diversified.
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.

Halted Securities: Secondary market trading of a security held by the ETF may be halted by a stock exchange because of market conditions or other reasons, such as extraordinary market volatility. Securities that have experienced a period without a readily available market quotation will be disclosed on this page.
ETF Market Performance (Inception to Date): The fund's per share Net Asset Value (NAV) is the value of one share of the fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which the shares of the fund are listed for trading, as of the time that the fund's NAV is calculated. The NAV Return is based on the NAV of the fund, and the Market Price Return is based on the market price per share of the fund. Since shares of the fund did not trade in the secondary market until after the fund's inception, for the period from inception to the first day of secondary market trading in shares of the fund, the NAV of the fund is used as a proxy for the Market Price to calculate market returns. Market Price and NAV returns assume that dividends and capital gain distributions have been reinvested in the fund at Market Price and NAV, respectively.
