MANAGEMENT’S DISCUSSION OF Portfolio PERFORMANCE
For the 12 months ended October 31, 2024, total returns were 30.21% for the Portfolio and 30.98% for the Russell 1000® Value Index, the Portfolio’s style benchmark (“benchmark”).
PERFORMANCE HIGHLIGHTS
U.S. equities had positive returns for the period. As measured by Russell indices, within the large cap universe, stocks with smaller market capitalizations underperformed larger stocks and value stocks underperformed growth stocks. High profitability stocks outperformed low profitability stocks within large cap stocks.
Relative to the benchmark, the Portfolio’s:
• Focus on value stocks detracted, as the index included growth stocks with relative prices too high for inclusion in the portfolio, which outperformed.
• Exclusion of highly regulated utilities detracted.

MANAGEMENT’S DISCUSSION OF Portfolio PERFORMANCE
For the 12 months ended October 31, 2024, total returns were 31.58% for the Portfolio and 31.12% for the MSCI United Kingdom Small Cap Index (net dividends), the Portfolio’s style benchmark (“benchmark”).
PERFORMANCE HIGHLIGHTS
United Kingdom equities had positive returns for the period. As measured by the MSCI United Kingdom indices, small cap stocks outperformed mid cap stocks, a subset of large cap stocks, and small value stocks outperformed small growth stocks.

• Exclusion of low profitability growth stocks contributed.
• Exclusion of small cap stocks with high asset growth contributed.
• Exclusion of REITs contributed.
• Focus on small cap stocks detracted, as large cap stocks held by the index outperformed.
