    USTREAS T-Bill Auction Ave 3 Montooltip: USTREAS T-Bill Auction Ave 3 Mon is an index that measures the performance of the average investment rate of U.S. Treasury bills (T-Bills) with a three-month maturity. Three-month T-Bills are short-term securities issued by the U.S. government that are generally considered to be risk-free. In calculating index results, Morningstar, the index provider, determines the arithmetic mean of the investment rates on all three-month T-Bills issued during a given month as reported by the U.S. Treasury's Bureau of the Public Debt. The investment rate is then converted into a price and a monthly return, assuming that the T-Bill is held to maturity.

Returns will vary, so investors may lose money. (American Funds U.S. Government Money Market Fund)
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/or summary prospectuses, which can be obtained from a financial professional and should be read carefully before investing.
The value of fixed income securities may be affected by changing interest rates and changes in credit ratings of the securities.

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.
