| Performance Narrative [Text Block] | This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Agency SL Shares has varied from year to year for the past seven calendar years. The table shows the average annual total returns for the past one year, five years and life of the Fund. Prior to the conversion of the Fund to a government money market fund, effective as of September 3, 2024, the Fund operated as an institutional prime money market fund and invested in certain types of securities that the Fund is no longer permitted to hold.
