| 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, 2026, as front-end yields ended lower amid elevated rate volatility, driven by moderating inflation expectations and Federal Reserve rate cuts during the second half of 2025. Relative to its style-specific benchmark, the Bloomberg 1–3 Year U.S. Government/Credit Index, the fund’s out-of-benchmark allocations to mortgage-backed securities (MBS), collateralized loan obligations, asset-backed securities, and residential and commercial MBS aided performance as spreads tightened. Similarly, an overweight to investment-grade corporate bonds and corresponding underweight to U.S. Treasuries contributed as corporate credit outperformed. Security selection within investment-grade corporate bonds also generated positive returns. Duration management over the period detracted from the fund’s returns relative to its style-specific benchmark amid elevated rate volatility. 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 decreased over the reporting period but continued to represent its largest absolute and relative position. The fund’s allocation to U.S. Treasuries and MBS increased. While we are primarily a cash bond manager, we employ the use of derivatives in our strategy for hedging purposes. The use of derivatives may include futures and options, as well as credit default swaps 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, 2026, as front-end yields ended lower amid elevated rate volatility, driven by moderating inflation expectations and Federal Reserve rate cuts during the second half of 2025. Relative to its style-specific benchmark, the Bloomberg 1–3 Year U.S. Government/Credit Index, the fund’s out-of-benchmark allocations to mortgage-backed securities (MBS), collateralized loan obligations, asset-backed securities, and residential and commercial MBS aided performance as spreads tightened. Similarly, an overweight to investment-grade corporate bonds and corresponding underweight to U.S. Treasuries contributed as corporate credit outperformed. Security selection within investment-grade corporate bonds also generated positive returns. Duration management over the period detracted from the fund’s returns relative to its style-specific benchmark amid elevated rate volatility. 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 decreased over the reporting period but continued to represent its largest absolute and relative position. The fund’s allocation to U.S. Treasuries and MBS increased. While we are primarily a cash bond manager, we employ the use of derivatives in our strategy for hedging purposes. The use of derivatives may include futures and options, as well as credit default swaps and interest rate swaps.
