Figures shown are past results and are not predictive of results in future periods. Current and future results may be lower or higher than those shown. Investing for short periods makes losses more likely. View mutual fund expense ratios and returns. View current mutual fund SEC yields.

Returns at net asset value (NAV) do not reflect a sales charge. If a sales charge had been deducted, the results would have been lower.
You could lose money by investing in American Funds® U.S. Government Money Market Fund. Although the fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in the fund is not a bank account and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The fund's sponsor is not required to reimburse the fund for losses, and you should not expect that the sponsor will provide financial support to the fund at any time, including during periods of market stress.
For money market funds, the annualized 7-day SEC yield more accurately reflects the fund's current earnings than does the fund's return.
Investments are not FDIC-insured, nor are they deposits of or guaranteed by a bank or any other entity, so they may lose value.
Investors should carefully consider investment objectives, risks, charges and expenses. This and other important information is contained in the fund prospectuses and summary prospectuses, which can be obtained from a financial professional and should be read carefully before investing. Similar information is contained in the CollegeAmerica Program Description, which can be obtained from a financial professional and should be read carefully before investing. CollegeAmerica is distributed by Capital Client Group, Inc., and sold through unaffiliated intermediaries.
Depending on your state of residence, there may be an in-state plan that provides state tax and other state benefits, such as financial aid, scholarship funds and protection from creditors, not available through CollegeAmerica. Before investing in any state's 529 plan, investors should consult a tax advisor. CollegeAmerica is a nationwide plan sponsored by Commonwealth Savers. 
The value of fixed income securities may be affected by changing interest rates and changes in credit ratings of the securities.
Visit the SEC website for the American Funds® U.S. Government Money Market Fund's most recent filings.
American Funds U.S. Government Money Market Fund may suspend 12b-1 payments under agreements between its principal underwriter and intermediaries and other entities that sell fund shares. To the extent such payments have been suspended for a certain share class, should payments subsequently commence, the fund's investment results would be lower and expenses would be higher for that share class. Please refer to the prospectus for additional information.
There have been periods when the results lagged the index(es) and/or average(s). The indexes are unmanaged and, therefore, have no expenses. Investors cannot invest directly in an index.

When applicable, results reflect fee waivers and/or expense reimbursements, without which they would have been lower and net expenses higher. Read details about how waivers and/or reimbursements affect the results for each fund. View results and yields without fee waiver and/or expense reimbursement.
