Factors Affecting Performance [Text Block]

How did the Fund perform last year ?

For the 12-month period ended December 31, 2024, the Fund’s Class A shares returned 4.45%.
In comparison, the Bloomberg Global Aggregate Index (Hedged) (the “Index”) returned 3.40% for the same period.

What affected the Fund’s performance?

Global fixed-income markets rose in response to the general, though not uniform, downtrend in government bond yields and a broad-based tightening of credit spreads.
Relative performance benefited from cross-market duration positioning, with overweight exposure to Australian, Korean and Swedish duration versus core markets, as well as active positioning in developed-markets inflation-linked products.
Detractors from relative performance included underweight exposure to Canadian duration versus the United States, and, to a lesser degree, overweight duration positions in select local emerging markets.

The above graph compares a hypothetical $10,000 investment in the Fund’s Class A shares to a hypothetical investment of $10,000 made in the Bloomberg Global Aggregate Index (Hedged) on 12/31/2014. The performance shown takes into account the maximum initial sales charge on Class A shares and applicable fees and expenses of the Fund, including management fees and other expenses.
