Investment objective & strategy

As of Nov. 25, 2025 · prospectus

Objective. The fund seeks current income.

Strategy. One Choice In Retirement Portfolio is a fund of funds, meaning that it seeks to achieve its objective by investing in other American Century mutual funds (the underlying funds) that represent a variety of asset classes and investment styles. The underlying stock funds draw on growth, value and quantitative investment techniques and diversify investments among small, medium and large U.S. and foreign companies. The underlying bond funds invest in fixed-income securities that vary by issuer type (corporate and government), credit quality (investment-grade and high-yield or junk bonds) and geographic exposure (domestic and international). Short-term investments include underlying funds that invest in fixed-income or debt instruments and have a shorter-term weighted average duration, typically three years or less.

The following table indicates the funds neutral mix; that is, how the funds investments generally will be allocated among the major asset classes as of the date of this prospectus. Equity Securities (Stock Funds) 45.0 % U.S. Equity 30.9 % International Equity 13.1 % Real Estate 1.0 % Fixed-Income Securities (Bond Funds) 44.6 % Short-Term Investments (Short-Term Funds) 10.4 % The neutral mix of One Choice In Retirement Portfolio is expected to remain fixed over time. The fund is generally intended for investors near to, at, or in retirement and who likely are no longer making new investments in the fund. The fund is designed for investors who plan to gradually withdraw the value of their account after retirement. The fund assumes a retirement age of 65 and may not be appropriate for an investor retiring at an age well before or after age 65. The portfolio managers regularly review the funds allocations to determine whether rebalancing is appropriate. In order to better balance risks in changing market environments, the portfolio managers may make modest deviations from the neutral mix in light of prevailing market conditions. We reserve the right to modify the neutral mix and underlying funds from time to time should circumstances warrant a change.
