MANAGEMENT’S DISCUSSION OF Portfolio PERFORMANCE

For the 12 months ended October 31, 2025, total returns were 3.75% for the Portfolio and 4.45% for the S&P Intermediate Term National AMT-Free Municipal Bond Index, the Portfolio’s style benchmark (“benchmark”).

PERFORMANCE HIGHLIGHTS

•	Within the Portfolio’s eligible investment range, bond yields changes were mixed. Realized term premiums were mixed, with intermediate-term municipal bonds outperforming shorter- and longer-term municipal bonds.

•	Realized credit premiums were positive, as lower-rated municipal bonds outperformed higher-rated municipal bonds.

Relative to the benchmark, the Portfolio’s:

•	Shorter duration detracted from relative performance during a period when shorter-term municipal bonds underperformed intermediate-term municipal bonds.

•	Underweight to single-A rated municipal bonds and overweight to AAA and AA rated municipal bonds detracted from relative performance as lower rated municipal bonds outperformed higher rated municipal bonds.

Factors Affecting Performance [Text Block]

MANAGEMENT’S DISCUSSION OF Portfolio PERFORMANCE

For the 12 months ended October 31, 2025, total returns were 5.28% for the Portfolio and 5.46% for the FTSE World Government Bond Index 1-3 Years, the Portfolio’s style benchmark (“benchmark”).

PERFORMANCE HIGHLIGHTS

•	Within the Portfolio’s eligible investment range, bond yield changes were mixed. 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 its benchmark, the Portfolio’s:

•	100% hedge to the US dollar detracted from performance relative to the unhedged benchmark as the US dollar generally depreciated relative to unhedged currencies in the benchmark.

•	Inclusion of corporate bonds contributed positively to performance relative to the government bond benchmark as corporate bonds outperformed government bonds.

MANAGEMENT’S DISCUSSION OF Portfolio PERFORMANCE

PERFORMANCE HIGHLIGHTS

•

Within the Fund’s eligible investment range, real and nominal yield changes were mixed. Realized real term premiums were mixed, with intermediate-term TIPS outperforming shorter- and longer-term TIPS. Longer-term TIPS were the worst performers. Nominal term premiums were negative within the eligible investment range, with longer-term bonds underperforming shorter-term bonds.

The Fund’s Equity Underlying Funds collectively underperformed the equity benchmark. Relative to the benchmark, the Fund’s:

•	Greater weight in U.S. stocks detracted from performance as U.S. stocks underperformed developed and emerging markets stocks.

•	Emphasis on value stocks detracted.

The Fund’s Inflation-Protected LDI Component’s Underlying Funds outperformed the blended fixed income and LDI benchmark for the period. Relative to its benchmark, the Underlying Funds’:

•	Inclusion of commercial paper and floating-rate notes contributed positively to relative performance as these bonds outperformed treasury bills.

•	Underweight to short- and long-term TIPS and overweight to intermediate-term TIPS contributed positively to relative performance.

•	Focus on small cap stocks detracted, as larger stocks held by the index outperformed.

Factors Affecting Performance [Text Block]

MANAGEMENT’S DISCUSSION OF Portfolio PERFORMANCE

For the 12 months ended October 31, 2025, total returns were 18.32% for the Portfolio and 20.81% for the Russell 3000® Index, the Portfolio’s benchmark.

PERFORMANCE HIGHLIGHTS

U.S. equities had positive returns for the period. As measured by Russell indices, small cap stocks underperformed large cap stocks, and mid cap stocks, a subset of large cap stocks, underperformed other large cap stocks and small cap stocks. Value stocks underperformed growth stocks as measured by the Russell indices. High profitability stocks underperformed low profitability stocks within large cap stocks and small cap stocks. The Fund’s sustainability considerations generally result in a lesser weight to companies in the energy and utilities sectors. Energy stocks underperformed the Russell 3000® Index. The Fund excludes real estate investment trusts (REITs) from purchase to allow investors to customize their real estate exposure. U.S. REITs underperformed U.S. equities as measured by the Dow Jones U.S. Select REIT Index and Russell indices.

Relative to the benchmark, the Portfolio’s:

•	Emphasis on stocks with smaller market capitalizations detracted.

•	Emphasis on value stocks detracted.

•	Exclusion of REITs contributed.

•	Sustainability considerations contributed.

MANAGEMENT’S DISCUSSION OF Portfolio PERFORMANCE

For the 12 months ended October 31, 2025, total returns were 6.97% for the Portfolio and 9.87% 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 cap stocks but outperformed 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. The Fund excludes from purchase small cap stocks with high asset growth. These stocks outperformed within the Russell 2000® Value Index. The Fund also excludes real estate investment trusts (REITs) from purchase to allow investors to customize their real estate exposure. U.S. REITs underperformed U.S. equities as measured by the Dow Jones U.S. Select REIT Index and Russell indices.

Relative to the benchmark, the Portfolio’s:

•	Emphasis on stocks with higher profitability 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 small cap stocks with high asset growth detracted.

•	Exclusion of REITs contributed.

For the 12 months ended October 31, 2025, total returns were 4.75% for the Portfolio and 5.29% for the FTSE World Government Bond Index 1-5 Years (hedged to USD), the Portfolio’s style benchmark (“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.

Relative to the benchmark, the Portfolio’s:

•	Shorter duration detracted from relative performance during a period when shorter-term bonds underperformed longer-term bonds.

MANAGEMENT’S DISCUSSION OF Portfolio PERFORMANCE

For the 12 months ended October 31, 2025, total returns were 13.57% for the Portfolio and 15.81% for the Portfolio’s custom benchmark, a hypothetical composite index composed of 65% S&P Global BMI Index (net dividends), the Portfolio’s equity benchmark, and 35% ICE BofA 1-3 Year Global Government Index (hedged to USD), the Portfolio’s fixed income benchmark.

PERFORMANCE HIGHLIGHTS

•	Global stocks had positive returns for the period. As measured by the S&P Global BMI indices, small cap stocks underperformed large cap stocks. Value stocks underperformed growth stocks. High profitability stocks underperformed low profitability stocks within large caps and small caps.

•

Global bond yield changes were mixed during the period. Realized term premiums were positive in the short- to intermediate-term maturity range, with intermediate-term bonds outperforming short-term bonds. Credit spreads remained narrow throughout the period. Realized credit premiums were positive, with corporate bonds outperforming government bonds.

Relative to the benchmark, the Portfolio’s:

•	Emphasis on stocks with smaller market capitalizations detracted.

•	Emphasis on value stocks detracted.

•	Greater weight in U.S. stocks detracted from performance as U.S. stocks underperformed developed and emerging markets stocks.

•

Inclusion of bonds in the three- to five-year maturity range contributed positively as these bonds outperformed bonds in the one- to three-year maturity range. Inclusion of corporate bonds also contributed to performance relative to the government bond index as corporate bonds outperformed government bonds.
