| Factors Affecting Performance [Text Block] |
Management's Discussion of Fund PerformanceThe following discussion compares the performance of the Fund to the ICE BofA 3-Month US Treasury Bill Index (the “Index”) to show how the Fund’s performance compares to the returns of similar investments for the reporting period. See the Average Annual Total Returns table below for the returns of the Fund and related indexes, including the Bloomberg US Aggregate Bond Index, which represents the overall U.S. fixed-income market. The Fund seeks to provide current income consistent with capital preservation while maintaining liquidity by investing primarily in a diversified portfolio of investment-grade securities. Top Contributors to Performance Sector and Security Selection both contributed positively to excess returns as asset-backed securities and investment-grade corporate debt securities outperformed U.S. Treasuries during the last fiscal year. Duration Management contributed positively to excess returns as the portfolio duration was positioned longer than the Index in a period of declining interest rates over the reporting period.
Top Detractors from Performance There were no material detractors from relative Fund performance.

Management's Discussion of Fund PerformanceThe following discussion compares the performance of the Fund to the Bloomberg BVAL Municipal Yield Curve (Callable) 3-Month Index (the “Index”) to show how the Fund’s performance compares to the returns of similar investments for the reporting period. See the Average Annual Total Returns table below for the returns of the Fund and related indexes including the S&P Municipal Bond Index, which represents the overall U.S. municipal fixed-income market. The Fund seeks to provide current income consistent with preservation of capital with an emphasis on maintaining liquidity on a tax-exempt basis. Top Contributors to Performance Credit allocation contributed positively to relative Fund performance with exposure to A-2-rated primarily variable-rate securities as well as AA-rated and A-rated or equivalent issuer ratings fixed-rate securities, all of which are excluded from the AAA-rated Index. Selective yield curve allocations to high quality, longer than Index bond/note maturities of approximately six months to two years (though largely one year) during periods when short-term municipal market yields peaked contributed to relative performance. The 1-year AAA-rated Bloomberg Evaluation Service municipal yield fluctuated over a wide range from 2.19% to 3.23%. Within this, specific sector contributions were from General Obligation-Local and Industrial Development/Pollution Control Revenue.
Top Detractors from Performance A significant allocation to daily and weekly Variable-Rate Demand Notes (“VRDNs”), important components for both liquidity and duration management, were a minor detraction from relative performance. The 7-day SIFMA Index rate, a proxy for weekly VRDNs, which fluctuated over a wide range, averaged 2.84% during the period. Duration management was a minor detractor from relative performance. While the Fund ended the fiscal year with a weighted average maturity (WAM) over 90 days, the average WAM was slightly shorter than the duration of the Index, where yields fluctuated over a wide range from 2.34% to 3.39% and ended the period lower by 31 basis points at 2.34% as the Federal Reserve lowered rates by 100 basis points.
