ARBMX Investment Objective and Strategy

One Choice 2020 Portfolio describes its objective and strategy as follows, from its latest prospectus filed with the SEC by American Century Asset Allocation Portfolios, Inc..

Investment objective

The fund seeks the highest total return consistent with its asset mix.

Principal investment strategy

One Choice 2020 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). The following table indicates the funds neutral mix; that is, how the funds investments generally will be allocated among the major asset classes. The table also shows the neutral weightings of each underlying fund currently being used within the various asset classes.

This information is as of the date of this prospectus. Equity Securities (Stock Funds) 46.00 % NT Core Equity Plus Fund 2.69 % NT Disciplined Growth Fund 1.78 % NT Emerging Markets Fund 0.13 % NT Equity Growth Fund 8.08 % NT Global Real Estate Fund 1.05 % NT Growth Fund 5.33 % NT Heritage Fund 1.98 % NT International Growth Fund 4.24 % NT International Small-Mid Cap Fund 0.56 % NT International Value Fund 4.72 % NT Large Company Value Fund 9.14 % NT Mid Cap Value Fund 4.23 % NT Non-U.S. Intrinsic Value Fund 0.11 % NT Small Company Fund 1.96 % Fixed-Income Securities (Bond Funds) 44.50 % Emerging Markets Debt Fund 1.22 % Global Bond Fund 7.79 % Inflation-Adjusted Bond Fund 3.28 % International Bond Fund 2.23 % NT Diversified Bond Fund 20.02 % NT High Income Fund 3.45 % Short Duration Inflation Protection Bond Fund 6.51 % Cash Equivalents (Money Market Fund) 9.50 % U.S.

Government Money Market Fund 9.50 % The target date in the fund name (2020) refers to the approximate year an investor plans to retire and likely would stop making new investments in the fund. The fund assumes a retirement age of 65 and may not be appropriate for an investor who plans to retire at or near the target date, but at an age well before or after 65. As the target date approaches, the funds neutral mix will become more conservative by decreasing the allocation to stocks and increasing the allocation to bonds and cash. By the time the fund reaches its target date, the neutral mix will become fixed and match that of One Choice In Retirement Portfolio, which is currently 45% stock funds, 45% bond funds and 10% money market funds. The fund is designed for investors who plan to withdraw the value of their account gradually after retirement.

The following chart shows how the neutral mix is expected to change over time according to a predetermined glide path. 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. In order to implement such deviations, the fund may purchase futures directly. We reserve the right to modify the neutral mix and underlying funds from time to time should circumstances warrant a change.
