Fund Summary

Fund/Class:
Fidelity® Government Money Market Fund/Fidelity Government Money Market Fund

Investment Objective

The fund seeks as high a level of current income as is consistent with preservation of capital and liquidity.

Fee Table

The following table describes the fees and expenses that may be incurred when you buy and hold shares of the fund.

Shareholder fees
(fees paid directly from your investment)

None

Annual operating expenses
(expenses that you pay each year as a % of the value of your investment)

Management feeA

0.25%

Distribution and/or Service (12b-1) fees

None

Other expensesA

0.17%

Total annual operating expenses

0.42%

A Adjusted to reflect current fees.

This example helps compare the cost of investing in the fund with the cost of investing in other funds.

Let's say, hypothetically, that the annual return for shares of the fund is 5% and that your shareholder fees and the annual operating expenses for shares of the fund are exactly as described in the fee table. This example illustrates the effect of fees and expenses, but is not meant to suggest actual or expected fees and expenses or returns, all of which may vary. For every $10,000 you invested, here's how much you would pay in total expenses if you sell all of your shares at the end of each time period indicated:

1 year

$ 43

3 years

$ 135

5 years

$ 235

10 years

$ 530

Principal Investment Strategies

  • Normally investing at least 99.5% of total assets in cash, U.S. Government securities and/or repurchase agreements that are collateralized fully (i.e., collateralized by cash or government securities).

Summary Prospectus

  • Investing in U.S. Government securities issued by entities that are chartered or sponsored by Congress, but whose securities are neither issued nor guaranteed by the U.S. Treasury.
  • Investing in compliance with industry-standard regulatory requirements for money market funds for the quality, maturity, and diversification of investments.

Principal Investment Risks

  • Interest Rate Changes. Interest rate increases can cause the price of a money market security to decrease.
  • Issuer-Specific Changes. A decline in the credit quality of an issuer or a provider of credit support or a maturity-shortening structure for a security can cause the price of a money market security to decrease.

An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the fund.

The fund will not impose a fee upon the sale of your shares, nor temporarily suspend your ability to sell shares if the fund's weekly liquid assets fall below 30% of its total assets because of market conditions or other factors.

Performance

The following information is intended to help you understand the risks of investing in the fund. The information illustrates the changes in the performance of the fund's shares from year to year. Past performance is not an indication of future performance.

Summary Prospectus

We will not send multiple copies of these documents to you and members of your family who share the same address. Instead, we will send only a single copy of these documents. This will continue for as long as you are a shareholder, unless you notify us otherwise. If at any time you choose to receive individual copies of any documents, please call 1-800-544-8544. We will begin sending individual copies to you within 30 days of receiving your call.
