Factors Affecting Performance [Text Block]

MANAGEMENT’S DISCUSSION OF Portfolio PERFORMANCE

For the 12 months ended October 31, 2024, total returns were 9.62% for the Portfolio and 8.74% for the FTSE Non-USD World Government Bond Index (hedged to USD), the Portfolio’s style benchmark (“benchmark”).

PERFORMANCE HIGHLIGHTS

• Bond yields decreased in the global developed markets. Term premiums were positive, with longer-term bonds outperforming shorter-term bonds.

Relative to the benchmark, the Portfolio’s:
• Overweight to intermediate-term bonds denominated in the Australian dollar and euro contributed positively to relative performance during a period when those intermediate-term bonds outperformed shorter-term bonds.
• Underweight to bonds denominated in Japanese yen contributed positively to relative performance as these bonds generally underperformed other global developed market bonds during the period.

MANAGEMENT’S DISCUSSION OF Portfolio PERFORMANCE

For the 12 months ended October 31, 2024, total returns were 31.53% for the Portfolio and 31.77% for the Russell 2000® Value Index, the Portfolio’s style benchmark (“benchmark”).

PERFORMANCE HIGHLIGHTS

U.S. equities had positive returns for the period. As measured by Russell indices, small cap stocks underperformed large and mid cap stocks, a subset of large cap stocks. Within small and mid caps, value stocks underperformed growth stocks as measured by the Russell indices. High profitability stocks underperformed low profitability stocks within small 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.
• Emphasis on higher profitability stocks detracted.
• Sustainability considerations contributed.
