Performance Narrative [Text Block]	The following information is intended to help you understand the risks of investing in the Fund. The following bar chart shows the changes in the Fund's performance from year to year, and the table compares the Fund's performance to the performance of a broad-based securities market index and an additional index  with investment characteristics similar to those of the Fund for the same period. In 2024, the Investment Adviser changed the Fund’s primary benchmark from the Bloomberg U.S. Securitized MBS/ABS/CMBS Index to the Bloomberg U.S. Aggregate Bond Index in accordance with changes to regulatory disclosure requirements. The Fund continues to use the Bloomberg U.S. Securitized MBS/ABS/CMBS Index as an additional benchmark that the Investment Adviser believes more closely reflects the Fund’s principal investment strategies. The Fund's performance information reflects applicable fee waivers and/or expense limitations in effect during the period presented. Absent such fee waivers/expense limitations, if any, performance would have been lower. The Fund's past performance (before and after taxes) is no guarantee of future results.

Performance Table Narrative	After-tax returns are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown, and the after-tax returns shown are not relevant to investors who hold their Fund shares through tax-advantaged arrangements such as 401(k) plans or individual retirement accounts (“IRAs”). In some cases the after-tax returns may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period.
