| Factors Affecting Performance [Text Block] | Management's Discussion of Fund Performance How did the Fund perform last year? For the partial year ended December 31, 2024, the AstraZeneca PLC ADRhedged returned -10.96%. In comparison, the AstraZeneca PLC ADR returned -17.32% for the same period. What key factors affected the Fund's performance? The prime driver for the over performance of the Fund vs the unhedged ADR is the 6.63% increase in value of the USD vs GBP over the inception date to year end. Driven by interest rate differentials and pro-growth policies, the USD is likely to continue to gain strength vs international currencies. Wider concerns about the strength of the UK economy had driven the pound lower in recent months. As measured by the DXY—the U.S. dollar index—the dollar has increased by 17.2% against developed economies since the pandemic. . | |
