Factors Affecting Performance [Text Block]
How did the Fund perform during the last year and what affected its performance?

The share class had a 7.27% total return in the 12 months ended April 30, 2026, compared with the ICE BofA 1-3 Year U.S. Corporate Index, which returned 4.33%, and the ICE BofA U.S. All Capital Securities Index, which returned 8.64%.

The Fund's benchmark, the ICE BofA 1–3 Year U.S. Corporate Index, focuses on investment-grade corporate bonds with maturities of one to three years. The Fund's primary objective is to seek to provide high current income, and its secondary objective is to provide capital preservation; we believe this is consistent with the benchmark over time. However, to meet its objectives, the Fund invests in low-duration preferred securities as well as shorter-term corporate bonds.

The Fund's allocations to over-the-counter fixed-to-reset preferred securities with six months to five years of call protection contributed to relative performance versus the ICE BofA 1–3 Year U.S. Corporate Index. Allocations to contingent capital securities (CoCos) with two to five years of call protection also contributed to relative performance.

The Fund's allocations to interest rate swaps and total return swaps, used to hedge and manage interest rate and credit risk modestly detracted from relative performance. While these hedges modestly detracted from performance, the portfolio's securities' returns more than offset the associated hedging costs. Allocations to exchange-traded fixed-to-float preferreds with more than five years of call protection also modestly detracted from relative performance.

By sector, the Fund's allocations to preferred securities in the banking, utilities and insurance sectors contributed the most to relative performance. No sectors detracted from relative performance.

Factors Affecting Performance [Text Block]
How did the Fund perform during the last year and what affected its performance?

The share class had a 7.17% total return in the 12 months ended April 30, 2026, compared with the ICE BofA 1-3 Year U.S. Corporate Index, which returned 4.33%, and the ICE BofA U.S. All Capital Securities Index, which returned 8.64%.

The Fund's benchmark, the ICE BofA 1–3 Year U.S. Corporate Index, focuses on investment-grade corporate bonds with maturities of one to three years. The Fund's primary objective is to seek to provide high current income, and its secondary objective is to provide capital preservation; we believe this is consistent with the benchmark over time. However, to meet its objectives, the Fund invests in low-duration preferred securities as well as shorter-term corporate bonds.

The Fund's allocations to over-the-counter fixed-to-reset preferred securities with six months to five years of call protection contributed to relative performance versus the ICE BofA 1–3 Year U.S. Corporate Index. Allocations to contingent capital securities (CoCos) with two to five years of call protection also contributed to relative performance.

The Fund's allocations to interest rate swaps and total return swaps, used to hedge and manage interest rate and credit risk modestly detracted from relative performance. While these hedges modestly detracted from performance, the portfolio's securities' returns more than offset the associated hedging costs. Allocations to exchange-traded fixed-to-float preferreds with more than five years of call protection also modestly detracted from relative performance.

By sector, the Fund's allocations to preferred securities in the banking, utilities and insurance sectors contributed the most to relative performance. No sectors detracted from relative performance.
