IMPORTANT HOLDINGS INFORMATION: The information shown above relates to U.S. Treasury Reserves Portfolio ("the Portfolio"), the registered investment company in which the Fund invests all of its investable assets. The Fund utilizes a master/feeder structure by investing all of its assets in a master portfolio. Assets are reported at the master portfolio level. The data in the “Value” column represents the market value of the Portfolio’s investments.

The Portfolio's investments are valued at amortized cost, which approximates market value, in accordance with Rule 2a-7 under the Investment Company Act of 1940 (the “1940 Act”). The amortized cost method of valuation involves valuing portfolio securities at their cost and thereafter assuming a constant amortization to maturity of any discount or premium.

The Portfolio's use of amortized cost is subject to its compliance with certain conditions as specified by Rule 2a-7 under the 1940 Act. The Portfolio continues to meet the requirements of Rule 2a-7 that permit it to utilize amortized cost to value its securities.

Portfolio holdings are subject to change at any time. Percentages are based on total investments. This information is provided for information purposes only and should not be construed as a recommendation to purchase or sell any security.

Risks

What Are The Risks?

You could lose money by investing in the 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. Although the fund invests in U.S. government obligations, an investment in the fund is neither insured nor guaranteed by the U.S. government.

All investments involve risk, including loss of principal. The fund's yield may be affected by changes in interest rates and changes in credit ratings. These and other risks are discussed in the fund’s prospectus.
