| Factors Affecting Performance [Text Block] |
What drove fund performance during the past 12 months?The shorter-maturity U.S. investment-grade bond market generated positive returns over the year ended May 31, 2025, as front-end yields fell amid elevated rate volatility, driven by heightened trade policy uncertainty and fiscal policy concerns near the end of the period. The fund’s overweight to investment-grade corporate bonds and corresponding underweight to U.S. Treasuries aided performance relative to its style-specific benchmark, the Bloomberg 1–3 Year U.S. Government/Credit Index, as corporate credit spreads tightened. Similarly, out-of-benchmark allocations to asset-backed securities, mortgage-backed securities (MBS), and commercial mortgage-backed securities contributed. Security selection within investment-grade corporate bonds generated positive returns. Duration management over the period detracted from the fund’s returns relative to its style-specific benchmark. The Short-Term Bond Fund seeks a high level of income consistent with minimal fluctuation in principal value and liquidity. The fund’s allocation to investment-grade corporate bonds marginally decreased over the reporting period but continued to represent its largest absolute and relative position. The fund’s allocation to U.S. Treasuries decreased slightly while our allocation to MBS increased. While we are primarily a cash bond manager, we occasionally employ the limited use of derivatives in our strategy for hedging purposes. The use of derivatives may include futures and options, as well as credit default and interest rate swaps.

| Factors Affecting Performance [Text Block] |
What drove fund performance during the past 12 months?The shorter-maturity U.S. investment-grade bond market generated positive returns over the year ended May 31, 2025, as front-end yields fell amid elevated rate volatility, driven by heightened trade policy uncertainty and fiscal policy concerns near the end of the period. The fund’s overweight to investment-grade corporate bonds and corresponding underweight to U.S. Treasuries aided performance relative to its style-specific benchmark, the Bloomberg 1–3 Year U.S. Government/Credit Index, as corporate credit spreads tightened. Similarly, out-of-benchmark allocations to asset-backed securities, mortgage-backed securities (MBS), and commercial mortgage-backed securities contributed. Security selection within investment-grade corporate bonds generated positive returns. Duration management over the period detracted from the fund’s returns relative to its style-specific benchmark. The Short-Term Bond Fund seeks a high level of income consistent with minimal fluctuation in principal value and liquidity. The fund’s allocation to investment-grade corporate bonds marginally decreased over the reporting period but continued to represent its largest absolute and relative position. The fund’s allocation to U.S. Treasuries decreased slightly while our allocation to MBS increased. While we are primarily a cash bond manager, we occasionally employ the limited use of derivatives in our strategy for hedging purposes. The use of derivatives may include futures and options, as well as credit default and interest rate swaps.
