Factors Affecting Performance [Text Block]	How did the Fund perform last year and what affected the Fund For the fiscal year ended September 30, 2024, the Fund’s Class A shares at NAV returned 15.18 The Fund’s benchmark relative performance benefited from allocations to non-agency mortgage-backed securities and to the financial sector, and a significant Fund underweight to U.S. Treasuries relative to the performance benchmark index. Security selection in the financials, industrials sectors and in agency mortgage-backed securities contributed to the Fund’s benchmark relative performance. The Fund’s longer average U.S. duration position relative to the benchmark index by 0.72 years, combined with yield curve positioning, outperformed as yields moved lower during the last two months of 2023 and again in the last four months of the period. The Fund’s out of benchmark index exposures to non-U.S. dollar holdings and insurance-linked securities contributed to the Fund’s benchmark-relative performance, while the allocation to convertible securities detracted.
