Unaudited

NOTES TO PORTFOLIO OF INVESTMENTS

T. Rowe Price U.S. Treasury Funds, Inc. (the corporation), is registered under the Investment Company Act of 1940 (the 1940 Act). The U.S. Treasury Intermediate Fund (the fund), a diversified, open-end management investment company, is one portfolio established by the corporation. The fund seeks a high level of income consistent with maximum credit protection and moderate fluctuation in principal.

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES

Basis of Preparation
The accompanying Portfolio of Investments was prepared in accordance with accounting principles generally accepted in the United States of America (GAAP), which require the use of estimates made by fund management. Fund management believes that estimates and security valuations are appropriate; however, actual results may differ from those estimates, and the security valuations reflected in the Portfolio of Investments may differ from the values ultimately realized upon sale of the securities.

Investment Transactions
Investment transactions are accounted for on the trade date.

New Accounting Pronouncement
In January 2010, new accounting guidance was issued that will require enhanced disclosures about fair value measurements in the financial statements; it is effective for fiscal years and interim periods beginning after December 15, 2009. Management expects that adoption of this guidance will have no impact on the fund’s net assets or results of operations.

NOTE 2 - VALUATION

The fund’s investments are reported at fair value as defined under GAAP. The fund values its investments and computes its net asset value per share at the close of the New York Stock Exchange (NYSE), normally 4 p.m. ET, each day that the NYSE is open for business.

Valuation Methods
Debt securities are generally traded in the over-the-counter (OTC) market. Securities with remaining maturities of one year or more at the time of acquisition are valued at prices furnished by dealers who make markets in such securities or by an independent pricing service, which considers the yield or price of bonds of comparable quality, coupon, maturity, and type, as well as prices quoted by dealers who make markets in such securities. Securities with remaining maturities of less than one year at the time of acquisitiongenerally use amortized cost in local currency to approximate fair value. However, if amortized cost is deemed not to reflect fair value or the fund holds a significant amount of such securities with remaining maturities of more than 60 days, the securities are valued at prices furnished by dealers who make markets in such securities or by an independent pricing service.

Investments in mutual funds are valued at the mutual fund’s closing net asset value per share on the day of valuation. Financial futures contracts are valued at closing settlement prices.

Other investments, including restricted securities, and those for which the above valuation procedures are inappropriate or are deemed not to reflect fair value are stated at fair value as determined in good faith by the T. Rowe Price Valuation Committee, established by the fund’s Board of Directors.

Valuation Inputs
Various inputs are used to determine the value of the fund’s investments. These inputs are summarized in the three broad levels listed below:

Level 1 – quoted prices in active markets for identical securities

Level 2 – observable inputs other than Level 1 quoted prices (including, but not limited to, quoted prices for similar securities, interest rates, prepayment speeds, and credit risk)

Level 3 – unobservable inputs

Observable inputs are those based on market data obtained from sources independent of the fund, and unobservable inputs reflect the fund’s own assumptions based on the best information available. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. The following table summarizes the fund’s investments, based on the inputs used to determine their values on February 28, 2010:

NOTE 3 - DERIVATIVE INSTRUMENTS

The fund may invest in derivative instruments. As defined by GAAP, a derivative is a financial instrument whose value is derived from an underlying security price, foreign exchange rate, interest rate, index of prices or rates, or other variable; it requires little or no initial investment and permits or requires net settlement. The fund invests in derivatives only if the expected risks and rewards are consistent with its investment objectives, policies, and overall risk profile, as described in its prospectus and Statement of Additional Information. The fund may use derivatives for a variety of purposes, such as seeking to hedge against declines in principal value, increase yield, invest in an asset with greater efficiency and at a lower cost than is possible through direct investment, or to adjust portfolio duration andcredit exposure. The risks associated with the use of derivatives are different from, and potentially much greater than, the risks associated with investing directly in the instruments on which the derivatives are based. Investments in derivatives can magnify returns positively or negatively; however, the fund at all times maintains sufficient cash reserves, liquid assets, or other SEC-permitted asset types to cover the settlement obligations under its open derivative contracts.

The fund values its derivatives at fair value, as described below and in Note 2, and recognizes changes in fair value currently in its results of operations. Accordingly, the fund does not follow hedge accounting, even for derivatives employed as economic hedges.

Counterparty risk related to exchange-traded derivatives, including futures and options contracts, is minimal because the exchange’s clearinghouse provides protection against defaults. Additionally, for exchange-traded derivatives, each broker in its sole discretion may change margin requirements applicable to the fund.

Futures Contracts
The fund may enter into futures contracts to manage exposure to interest rate and yield curve movements, security prices, foreign currencies, credit quality, and mortgage prepayments; as an efficient means of adjusting exposure to all or part of a target market; to enhance income; as a cash management tool; and/or to adjust portfolio duration and credit exposure.A futures contract provides for the future sale by one party and purchase by another of a specified amount of a specific underlying financial instrument at an agreed upon price, date, time, and place. The fund currently invests only in exchange-traded futures, which generally are standardized as to maturity date, underlying financial instrument, and other contract terms. Upon entering into a futures contract, the fund is required to deposit with the broker cash or securities in an amount equal to a certain percentage of the contract value (initial margin deposit); the margin deposit must then be maintained at the established level over the life of the contract. Subsequent payments are made or received by the fund each day to settle daily fluctuations in the value of the contract (variation margin), which reflect changes in the value of the underlying financial instrument. Variation margin is recorded as unrealized gain or loss until the contracts are closed. For a futures contract, the value included in net assets is the amount of unsettled variation margin, if any. Risks related to the use of futures contracts include possible illiquidity of the futures markets, contract prices that can be highly volatile and imperfectly correlated to movements in hedged security values, interest rates, and/orcurrency values, and potential losses in excess of the fund’s initial investment.

NOTE 4 - FEDERAL INCOME TAXES

At February 28, 2010, the cost of investments for federal income tax purposes was $518,566,000. Net unrealized gain aggregated $15,806,000 at period-end, of which $16,825,000 related to appreciated investments and $1,019,000 related to depreciated investments.

NOTE 5 - RELATED PARTY TRANSACTIONS

The fund may invest in the T. Rowe Price Reserve Investment Fund and the T. Rowe Price Government Reserve Investment Fund (collectively, the T. Rowe Price Reserve Investment Funds), open-end management investment companies managed by T. Rowe Price Associates, Inc. (Price Associates) and considered affiliates of the fund. The T. Rowe Price Reserve Investment Funds are offered as cash management options to mutual funds, trusts, and other accounts managed by Price Associates and/or its affiliates and are not available for direct purchase by members of the public. The T. Rowe Price Reserve Investment Funds pay no investment management fees.

Unaudited

NOTES TO PORTFOLIO OF INVESTMENTS

T. Rowe Price U.S. Treasury Funds, Inc. (the corporation), is registered under the Investment Company Act of 1940 (the 1940 Act). The U.S. Treasury Money Fund (the fund), a diversified, open-end management investment company, is one portfolio established by the corporation. The fund seeks maximum preservation of capital and liquidity and, consistent with these goals, the highest possible current income.

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES

Basis of Preparation
The accompanying Portfolio of Investments was prepared in accordance with accounting principles generally accepted in the United States of America, which require the use of estimates made by fund management. Fund management believes that estimates and security valuations are appropriate; however, actual results may differ from those estimates, and the security valuations reflected in the Portfolio of Investments may differ from the values ultimately realized upon sale of the securities.

Investment Transactions
Investment transactions are accounted for on the trade date.

New Accounting Pronouncement
In January 2010, new accounting guidance was issued that will require enhanced disclosures about fair value measurements in the financial statements; it is effective for fiscal years and interim periods beginning after December 15, 2009. Management expects that adoption of this guidance will have no impact on the fund’s net assets or results of operations.

NOTE 2 - VALUATION

The fund values its investments and computes its net asset value per share each day that the New York Stock Exchange is open for business. In accordance with Rule 2a-7 under the 1940 Act, securities are valued at amortized cost, which approximates fair value. Securities for which amortized cost is deemed not to reflect fair value are stated at fair value as determined in good faith by the T. Rowe Price Valuation Committee, established by the fund’s Board of Directors.

Various inputs are used to determine the value of the fund’s investments. These inputs are summarized in the three broad levels listed below:

Level 1 – quoted prices in active markets for identical securities

Level 2 – observable inputs other than Level 1 quoted prices (including, but not limited to, quoted prices for similar securities, interest rates, prepayment speeds, and credit risk)

Level 3 – unobservable inputs

Observable inputs are those based on market data obtained from sources independent of the fund, and unobservable inputs reflect the fund’s own assumptions based on the best information available. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, securities held by a money market fund are generally high quality and liquid; however, they are reflected as Level 2 because the inputs used to determine fair value are not quoted prices in an active market. On February 28, 2010, all of the fund’s investments were classified as Level 2, based on the inputs used to determine their values.

NOTE 3 - OTHER INVESTMENT TRANSACTIONS

Consistent with its investment objective, the fund engages in the following practices to manage exposure to certain risks and/or to enhance performance. The investment objective, policies, program, and risk factors of the fund are described more fully in the fund’s prospectus and Statement of Additional Information.

Repurchase Agreements
The fund may invest in repurchase agreements. All repurchase agreements are fully collateralized by U.S. government securities. Collateral is in the possession of the fund’s custodian or, for tri-party agreements, the custodian designated by the agreement. Collateral is evaluated daily to ensure that its market value exceeds the delivery value of the repurchase agreements at maturity. Although risk is mitigated by the collateral, the fund could experience a delay in recovering its value and a possible loss of income or value if the counterparty fails to perform in accordance with the terms of the agreement.

NOTE 4 - FEDERAL INCOME TAXES

At February 28, 2010, the cost of investments for federal income tax purposes was $1,784,469,000.
