HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE?
Large-cap equities maintained market leadership in 2024, as the market reconsidered the prospect of a major decline in the Federal Funds rate. Mid-cap equities, which are more rate sensitive, traded up as the Federal Reserve began to cut interest rates, but gave up some of these gains amid inflation and growth concerns to start 2025. The Fund underperformed the Russell 1000 Index due to stock selection in the consumer discretionary, industrials, and technology sectors.

HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE?
Emerging markets rose during the trailing 12 months, with broad-based strength across geographies. Chinese equities rebounded on hopes of supportive fiscal and monetary policy. While investors considered a potential recovery in the Chinese economy, many other emerging markets, across Asia, Latin America, and Eastern Europe, also posted strong returns.
China, Taiwan, and India drove absolute Fund performance during the past 12 months. On the other hand, South Korea and Brazil declined, against a backdrop of political and economic uncertainty in both markets. The Fund’s overweight to South Korea and Brazil, and stock selection in China caused the Fund to underperform the MSCI Emerging Markets Index.

The Fund rose during the period but underperformed the MSCI World ex USA IMI. Stock selection in the industrials and consumer staples sectors, and stock selection in the United Kingdom were the largest drivers of underperformance relative to the MSCI World ex USA IMI.
