| Factors Affecting Performance [Text Block] | What drove fund performance during the past 12 months? Non-U.S. developed markets stocks recorded a double-digit return over the 12-month reporting period as anticipation of interest rate cuts by global central banks outweighed concerns about rising geopolitical tensions and persistent inflation in many markets. Consumer discretionary stocks contributed the most to relative performance versus the MSCI EAFE Index Net due to positive selection and an underweight to the sector, which trailed the index return. Financials helped relative returns largely owing to positive stock selection and an overweight to the sector, which outperformed the benchmark. Information technology detracted the most from relative performance due to adverse stock selection. However, an overweight to the IT sector, which outpaced the benchmark, tempered the impact of negative stock selection. Communication services also weighed on relative returns owing to negative stock selection. The fund seeks to generate strong after-tax returns by using a strategic investment approach leveraging the fundamental research produced by the firm’s global analyst team combined with active tax management. Bottom-up stock selection, informed by an awareness of the global macro backdrop and the outlook for specific industries, sectors, and countries, drives the fund’s allocations. Financials was the largest overweight sector at period-end, while industrials and business services was the largest underweight. |
