Factors Affecting Performance [Text Block] | How did the Fund perform last year and what impacted its performance? Management's Discussion of Fund Performance United States (U.S.) fixed income sectors generated positive total returns during the trailing twelve-month period ended July 31, 2025, as measured by the Bloomberg U.S. Aggregate Bond Index. On an excess return basis, credit sectors produced positive returns over duration-equivalent government bonds as spreads compressed, with higher-yielding sectors generally performing best.

The Fund held tactical interest rate positions during the period, including interest rate futures and swaps; overall duration and yield curve positioning detracted from relative results. During the period, the Fund used currency forwards and options to implement non-US rate and currency positions which had a negligible impact on performance, in aggregate. Credit default swaps (CDX) were used to manage credit exposure and overall portfolio risk. EM credit default swap (CDX) positions had a neutral impact on performance during the period, and a small allocation to investment grade CDX also had a muted impact.
