MANAGEMENT’S DISCUSSION OF Portfolio PERFORMANCE

For the 12 months ended October 31, 2025, total returns were 22.89% for the Portfolio and 24.54% for the MSCI Emerging Markets Value Index (net dividends), the Portfolio’s style benchmark (“benchmark”).

PERFORMANCE HIGHLIGHTS

Emerging markets had positive returns for the period. As measured by the MSCI Emerging Markets indices, small cap stocks underperformed mid cap stocks, a subset of large cap stocks, and underperformed other large cap stocks. Mid cap stocks underperformed large cap stocks. Within large cap stocks, value stocks underperformed growth stocks as measured by the MSCI Emerging Markets indices. Small cap value stocks underperformed large cap value stocks. High profitability stocks outperformed low profitability stocks within large caps and small caps.

Relative to the benchmark, the Portfolio’s:

•	Emphasis on stocks with smaller market capitalizations detracted.

•	Focus on value stocks detracted, as the index included stocks with relative prices too high for inclusion in the portfolio, and these stocks outperformed.

•	Exclusion of highly regulated utilities contributed.

Factors Affecting Performance [Text Block]

MANAGEMENT’S DISCUSSION OF Portfolio PERFORMANCE

For the 12 months ended October 31, 2025, total returns were 21.07% for the Portfolio and 21.45% for the S&P 500 Index, the Portfolio’s benchmark.

PERFORMANCE HIGHLIGHTS

•	Within the Portfolio’s eligible investment range, bond yields decreased. Realized term premiums were positive, with longer-term bonds outperforming shorter-term bonds.

•	Credit spreads were relatively narrow throughout the period. Realized credit premiums were positive, as corporate bonds outperformed government bonds.

Relative to the benchmark, the Portfolio’s:

•	Emphasis to bonds with maturities shorter than three-months, within the fixed income collateral pool, detracted from relative performance, as these bonds underperformed the financing cost of the S&P futures.
