Strategy [Heading]

Principal Investment Strategies:

Strategy Narrative [Text Block]

As a fundamental policy, which cannot be changed without shareholder approval, the Fund invests only in:

• U.S. Treasury obligations maturing in 397 days or less.

• Repurchase agreements fully collateralized by U.S. Treasury obligations.

The Fund may invest in U.S. Treasury obligations or repurchase agreements without limit in order to qualify as a “government money market fund” in connection with amendments adopted by the U.S. Securities and Exchange Commission to Rule 2a-7 and other rules governing money market funds, under the Investment Company Act of 1940, as amended. Although the Fund intends to be fully invested in these instruments, it may hold a de minimis amount of cash for a short period prior to investment or payment of the proceeds of redemption. As a government money market fund, the Fund must invest at least 99.5% of its total assets in cash, government securities and/or repurchase agreements that are “collateralized fully” (i.e., backed by cash or government securities). Additionally, as a government money market fund, the Fund is not required to impose a liquidity fee and/or temporary redemption gate if the Fund’s weekly liquid asset fall below 30% of its total assets. While the Fund’s Board of Trustees may elect to subject the Fund to liquidity fee and gate requirements in the future, it has not elected to do so at this time.

The Fund will maintain an average maturity computed on a dollar-weighted basis of 60 days or less and a dollar-weighted average life of 120 days or less.

Risk [Heading]

Principal Investment Risks:

Risk Narrative [Text Block]

Although the Fund invests in short-term Treasury obligations, an investment in the Fund is subject to risk even if all securities in the Fund are paid in full at maturity. All money market instruments, including U.S. Treasury obligations, can change in value in response to changes in interest rates, and a major change in rates could cause the share price to change. While U.S. Treasury obligations are backed by the full faith and credit of the U.S. government, an investment in the Fund is neither insured nor guaranteed by the Federal Deposit Insurance Corporation, U.S. government or any other government agency. Thus, while the Fund seeks to maintain a stable net asset value of $1.00 per share, there is no assurance that it will do so. It is possible to lose money by investing in the Fund. If the seller of a repurchase agreement in which the Fund invests defaults on its obligation or declares bankruptcy, the Fund may experience delays in selling the securities underlying the repurchase agreement. As a result, the Fund may incur losses arising from a decline in the value of those securities, reduced levels of income, and expenses of enforcing its rights. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not expect that the sponsor will provide financial support to the Fund at any time.
