SUPPLEMENTARY NOTES TO SCHEDULE OF INVESTMENTS 

1. Underlying Funds

The fund invests in varying combinations of other mutual funds and exchange-traded funds advised by American Century Investments (the underlying funds). The fund’s asset allocation is intended to diversify investments among stocks, bonds, and short-term investments. The portfolio holdings of each underlying fund are available at americancentury.com, avantisinvestors.com or upon request at 1-800-345-2021.

2. Investment Valuations

The fund determines the fair value of its investments and computes its net asset value (NAV) per share at the close of regular trading (usually 4 p.m. Eastern time) on the New York Stock Exchange (NYSE) on each day the NYSE is open. The value of investments of the fund is determined by American Century Investment Management, Inc. (ACIM) (the investment advisor), as the valuation designee, pursuant to its valuation policies and procedures. The Board of Directors oversees the valuation designee and reviews its valuation policies and procedures at least annually.

Open-end management investment companies are valued at their reported NAV. Exchange-traded funds are listed or traded on a domestic securities exchange and are valued at the last reported sales price or at the official closing price as provided by the exchange.

3. Fair Value Measurements

The fund's investments valuation process is based on several considerations and may use multiple inputs to determine the fair value of the investments held by the fund. In conformity with accounting principles generally accepted in the United States of America, the inputs used to determine a valuation are classified into three broad levels. 

•Level 1 valuation inputs consist of unadjusted quoted prices in an active market for identical investments.

•Level 2 valuation inputs consist of direct or indirect observable market data (including quoted prices for comparable investments, evaluations of subsequent market events, interest rates, prepayment speeds, credit risk, etc.). These inputs also consist of quoted prices for identical investments initially expressed in local currencies that are adjusted through translation into U.S. dollars. 

•Level 3 valuation inputs consist of unobservable data (including a fund’s own assumptions).

The level classification is based on the lowest level input that is significant to the fair valuation measurement. The valuation inputs are not necessarily an indication of the risks associated with investing in these securities or other financial instruments.

As of period end, the fund's investment securities were classified as Level 1. The Schedule of Investments provides additional information on the fund's portfolio holdings.
