 This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.
Expense Example by, Year, Caption [Text] rr_ExpenseExampleByYearCaption The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based upon these assumptions your costs would be:

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies:
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

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. 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.


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.

Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration 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.
Risk [Heading] rr_RiskHeading Principal Investment Risks:
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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.

·


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. 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.


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] rr_RiskHeading Principal Investment Risks:
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

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.
