What affected the Fund’s performance? • Easing U.S. monetary policy and a greater appetite for risk helped drive strong market returns during the period. • On a sector basis, the Fund benefited most from stock selection in the materials sector, attributable to a gold miner holding and another mining stock that was a takeover target. • On a country basis, the Fund benefited most from its underweight position in Japan, which underperformed the wider market, and from security selection in Spain. • On a sector basis, information technology detracted most from relative performance, largely due to zero exposure to two low-yielding Index heavyweights. | |

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? • For the 12-month period ended October 31, 2024, the Fund’s Class C shares returned 9.23%. • In comparison, the Bloomberg Global Aggregate ex USD Index (Unhedged) (the “Index”) returned 8.65% for the same period. What affected the Fund’s performance? • The weakening of the U.S. dollar increased the total return of the Fund adding to the impact of a broad-based downtrend in yields. • The Fund’s performance relative to the Index benefited significantly from overweight U.S. duration exposure, with additional exposure added in October 2023 and April 2024. • Active positioning in developed-market, inflation-linked products further enhanced the Fund’s relative returns. • The Fund’s relative performance suffered from underweight exposure to Canadian versus U.S. duration. • Active foreign exchange positioning also detracted from relative returns. | |

The graph and table do not reflect the deduction of taxes that a shareholder would pay on fund distributions or redemption of fund shares. Cumulative Performance from November 1, 2014 through October 31, 2024 Initial Investment of $10,000 Years Ended 10/31 The above graph compares a hypothetical $10,000 investment in the Fund’s Class C shares to a hypothetical investment of $10,000 made in the Bloomberg Global Aggregate ex USD Index (Unhedged) (the “Index”) on 10/31/2014. The performance shown takes into account the maximum deferred sales charge on Class C shares and applicable fees and expenses of the Fund, including management fees, 12b-1 fees and other expenses. The Fund’s performance also assumes the reinvestment of dividends and capital gains. Unlike the Fund, the Index is not subject to charges, fees and other expenses.
