Keep this amendment with your prospectus. Each fund’s prospectus consists of this amendment and the fund’s prospectus, as supplemented to date (which is incorporated herein by reference). For additional information about a fund, you should refer to its prospectus and statement of additional information, in each case as supplemented to date, except where specific information is provided in this amendment, in which case the disclosure provided in this amendment is controlling.

For each of the funds within the American Funds Target Date Retirement Series listed above, the returns for Class A shares in the “Average annual total returns” table in the “Investment results” section are amended to read as follows. For these funds, the returns for Class A shares for the 1 year, 5 year, 10 year and lifetime periods ending December 31, 2022 that were originally disclosed in the prospectus dated January 1, 2024 did not correctly reflect the deduction of sales charges applicable to Class A shares. The returns in the tables below reflect the maximum sales charge applicable to Class A shares for all periods shown. Therefore the returns for Class A shares for all periods in the tables below are lower than the returns that were previously disclosed for these funds in the prospectus dated January 1, 2024. Average annual total returns for other share classes remain unchanged.
