Performance data quoted represents past performance and is no guarantee of future results. Current performance may be lower or higher than the performance data quoted. Investment return and principal value will fluctuate so that an investor's shares, when redeemed, may be worth more or less than the original cost. Returns less than one year are not annualized. Net asset value (NAV) prices are used to calculate market price performance prior to the date when the fund first traded on the New York Stock Exchange. Market performance is determined using the bid/ask midpoint at 4:00 p.m. Eastern time, when the NAV is typically calculated. Market performance does not represent the returns you would receive if you traded shares at other times. Index performance does not represent the fund's performance. It is not possible to invest directly in an index.
Average annual returns illustrate the annual compounded returns that would have produced the cumulative total return if the fund's performance had remained constant throughout the period indicated. Returns for periods less than one year are not annualized.
30-Day SEC Unsubsidized Yield: Represents net investment income earned by a fund over a 30-day period, expressed as an annual percentage rate based on the fund's share price at the end of the 30-day period. Unsubsidized yield does not adjust for any fee waivers and/or expense reimbursements in effect.
12 Month Distribution Rate: The sum of a fund's total trailing 12-month interest and dividend payments divided by the most recent day's ending share price (NAV).
Yield to Worst: Lowest yield possible for a security given the current price, taking into account both call dates and maturity.
Yield to Maturity: The internal rate of return of the security based on the given market price—it is the single discount rate that equates a security price (inclusive of accrued interest) with its projected cashflows.

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.
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.
Generally, as interest rates rise, the value of the securities held in the fund will decline. The opposite is true when interest rates decline.
The lower rated securities in which the fund invests are subject to greater credit risk, default risk and liquidity risk.
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.

ICE BofA BB-B US High Yield Constrained Index
The ICE BofA BB-B US High Yield Constrained Index is composed of U.S. dollar-denominated corporate debt publicly issued in the U.S. market rated BB through B, based on an average of Moody's, S&P and Fitch ratings, with issuer exposure capped at 2%.
Closing Price: The price of the last reported trade on the fund's primary exchange.
Bid Ask Midpoint: The midpoint between the highest bid and the lowest offer on the primary listing exchange, as of the time that the Fund's NAV is calculated, generally around 4 p.m. (Eastern time).
Premium Discount: A premium is the amount that the fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the fund is trading below the reported NAV, expressed as a percentage of the NAV.
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.
Weighted Average Coupon: The weighted average interest rate paid by the securities in the pool.
Option Adjusted Duration (OAD): OAD is the effective duration. It is a duration calculation for bonds that have embedded options. This measure of duration takes into account the fact that expected cash flows will fluctuate as interest rates change. The effective duration measures the percentage change in price for a 100 basis points parallel shift in the yield curve. Positive duration means that as rates rise, the price decreases, and negative duration means that as rates rise, the price increases.
Option Adjusted Spread (OAS): The measurement of the spread (in basis points) of a fixed-income security rate and the risk-free rate of return, which is adjusted to take into account an embedded option.
Holdings: The number of holdings in the fund excluding cash positions and derivatives such as futures and currency forwards.
Investment Blend: Reflects the blend of securities owned by a fund. For example, the percentage of foreign or domestic stocks held by an equity fund or the percentage of corporate and government securities owned by a bond fund. The U.S./Foreign Convertibles grouping includes Convertible Bonds, Equity Linked Securities and Convertible Preferred securities.
Top Holdings: This value represents the top holdings included in the portfolio on a percent of assets basis. Holdings are subject to change without notice. Shares are units of ownership interest in a corporation or financial asset that provide for an equal distribution in any profits, if any are declared, in the form of dividends. In the context of debt instruments, principal can refer to the face value, or par value, of a bond—that is, the actual amount listed on the bond itself. American Century Investments publishes this listing of identities and quantities of each position held by the fund on each business day, before commencement of trading. Securities are reported at market value. The portfolio data and its presentation here may differ from the complete schedules of investments in regulatory filings due to differing accounting and reporting requirements.
Quality: Describes the portfolio of the fund in terms of the quality ratings of the securities it holds. Cash and cash equivalents include payable amounts related to securities purchased but not settled at period end. Credit quality ratings on underlying securities of a fund are obtained from three Nationally Recognized Statistical Rating Organizations ("NRSROs"), Standard & Poor's, Moody's and Fitch. Ratings are converted to the equivalent Standard & Poor's rating category for purposes of presentation. The median rating is used for securities rated by all three NRSROs. The common rating is used when two of the three NRSROs agree. The lower rating is used when only two NRSROs rate a security. A "nonrated" designation is assigned when a public rating is not available for a security. This designation does not necessarily indicate low credit quality. The letter ratings are provided to indicate the credit worthiness of the underlying bonds in the portfolio and generally range from AAA (highest) to D (lowest). Includes payable amounts related to securities purchased but not settled at period end.
Maturity: Describes the portfolio of the fund in terms of the different maturities of the securities it holds.
Weighted Average Life to Maturity (WALM): Is a measure of the sensitivity of a fixed income portfolio to interest rate changes. WALM is the average time in years to receive the principal repayments. Accordingly, WALM reflects how a portfolio would react to deteriorating credit or tightening liquidity conditions.
Duration: Describes the portfolio of the fund in terms of the different durations of the securities it holds.
