Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The A Class of the Fund returned 13.77% (with sales charges) and 19.46% (without sales charges) for the twelve months ended January 31, 2026, compared to the Bloomberg Global-Aggregate Total Return Index Value Hedged USD return of 4.71% and the JPMorgan EMBI Global Diversified Index return of 13.45%.

• Developing market debt benefited from easing global monetary conditions over the period, supported by U.S. dollar weakness and the Federal Reserve’s resumption of rate cuts in the second half, while geopolitical and trade‑policy risks were largely concentrated in developed markets.

• The Fund’s diversified strategy across local‑ and hard‑currency developing market debt, informed by a combination of top‑down macro views and bottom‑up country analysis, was strong during the period.

• Positive absolute contribution to performance was driven by country exposures, with positions in Zambia, Egypt, Nigeria, Ghana, and Kenya among the largest contributors, while exposure to Senegal detracted during the period.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The A Class of the Fund returned 2.69% (with sales charges) and 6.69% (without sales charges) for the twelve months ended January 31, 2026, compared to the Bloomberg U.S. Aggregate Bond Index return of 6.85%.

• The investment strategy of the Fund’s sub-advisor utilizes both bottom-up and top-down inputs to select the best relative value securities available across a broad range of domestic fixed income sectors.

• The period benefited from an improving policy and credit backdrop, as the Federal Reserve cut rates three times from September through December, supporting fixed income and credit assets overall, despite a rocky market environment in early April surrounding Liberation Day.

• Corporate Bonds were the largest positive contributors to performance, followed by U.S. Treasuries, Mortgage‑Backed Securities, and Asset‑Backed Securities, reflecting broad strength across fixed income sectors during the period.
