Factors Affecting Performance [Text Block]  

How did the Portfolio perform last year and what affected its performance?

The Portfolio underperformed its benchmark for the period. The U.S. equity market had strong returns during the period.

Changes to the Portfolio's portfolio were minimal. The Portfolio typically favors these characteristics: attractive valuation, earnings consistency, profitability, and improving market sentiment. Negative stock selection within information technology, health care, and communication services detracted from relative performance. The three largest individual detractors from relative performance over the 12-month period were Science Applications International Corp. and underweights to Intel Corp. and Sandisk Corp.

Relative performance was supported by positive stock selection within the financials, materials, and industrials sectors. The largest individual contributors to relative performance were KLA Corp., EMCOR Group, Inc., and Vertiv Holdings Co. A modest underweight to consumer discretionary contributed to performance. However, variations in sector weights versus the index were relatively small, which is typical for the strategy.

Factors Affecting Performance [Text Block]  

How did the Portfolio perform last year and what affected its performance?

The Fund outperformed its benchmark for the period. The past year saw a wide set of narratives drive the economy and financial markets. From an initial focus on tariffs, markets swiftly moved onto opportunities within artificial intelligence (AI). Geopolitical risk remained elevated. U.S. economic growth was above trend, supported by AI-driven capital expenditures and resilient consumer spending. Inflation remained above target. Outside the U.S., investment opportunities were divergent. Globally, expectations for earnings growth remain concentrated in a single theme: AI.

Portfolio positioning remained dynamic. One key decision was increasing exposure to commodities, where we started the period with no allocation. Equity exposure moderated higher for the first 10 months of the period, followed by a reduction closer to neutral while positioning rates remained underweight. Exposure to tactical asset allocation and commodities drove performance. No major portfolio components detracted significantly from the benchmark.

Factors Affecting Performance [Text Block]  

How did the Portfolio perform last year and what affected its performance?

The Portfolio underperformed its benchmark for the period. Over the past 12 months, U.S. equity leadership broadened beyond large-cap growth as improving expectations for monetary easing and domestic growth renewed interest in small-cap equities following early 2025 volatility and tariff uncertainty. Within small caps, performance was led by lower-quality companies as risk appetite rebounded, creating a headwind for quality oriented managers. As 2025 progressed, leadership broadened and fundamentals became more influential. Small-cap value benefited from attractive valuations, improving earnings trends, and domestic sensitivity.

Consistent with its philosophy, the Portfolio remained focused on higher-quality businesses, which lagged through much of the period but became better aligned as investors refocused on quality factors. Our underweight positions in the lagging real estate and utilities sectors contributed to relative performance while the information technology and health care sectors were the largest detractors.

Factors Affecting Performance [Text Block]  

How did the Portfolio perform last year and what affected its performance?

The Portfolio outperformed its benchmark for the period. The market was shaped by frequent repricing of Federal Reserve expectations and bouts of rate volatility driven by trade headlines, increasing investment in artificial intelligence, and geopolitical conflict. Despite this volatility, interest rates generally remained within a range while demand for credit was resilient and most risk assets performed well.

Our positioning was nimble, as we adjusted credit exposure during tariff- and geopolitically driven volatility. We maintained an overweight to mortgage-backed securities (MBS). Sector positioning was the largest contributor to performance. Security selection within MBS also contributed as elevated interest rate volatility and price dislocations provided opportunities to extract relative value. Our tactical positioning in the credit sector contributed, as did a sector overweight and security selection within asset-backed securities. Security selection within credit was a small detractor, driven primarily by technology holdings. Our underweight to commercial mortgage-backed securities also modestly detracted as the sector performed well.

Factors Affecting Performance [Text Block]  

How did the Portfolio perform last year and what affected its performance?

The Portfolio outperformed its benchmark for the period. International equity markets had strong returns during the period.

Changes to the Portfolio's portfolio were minimal. Characteristics typically favored in the portfolio include attractive valuation, earnings consistency, profitability, and improving market sentiment. Stock selection was the main driver of outperformance, adding value in 8 of 11 sectors. This was primarily due to strong stock selection within the industrials, health care, and consumer staples sectors. The largest individual contributors to relative performance were Siemens Energy AG, Inpex Corp., and Sumitomo Electric Industries. A modest underweight to communication services also contributed. However, variations in sector weights versus the index were relatively small, which is typical for the strategy.

Negative stock selection within information technology, real estate, and consumer discretionary detracted from relative performance. The top three individual detractors from relative performance were Oracle Corp. Japan, Pandora AS, and Renault SA (This security was no longer held at the end of the reporting period.).

Factors Affecting Performance [Text Block]  

How did the Portfolio perform last year and what affected its performance?

The Portfolio outperformed its benchmark for the period. The past year saw a wide set of narratives drive the economy and financial markets. From an initial focus on tariffs, markets swiftly moved onto opportunities within artificial intelligence (AI) followed by a U.S. government shutdown that lead to a dearth of data. Geopolitical risk remained. U.S. economic growth remained above trend, supported initially by AI-driven capital expenditures and resilient consumer spending. Inflation remained above target. Outside the U.S., investment opportunities were divergent. Globally, expectations for earnings growth remain concentrated in one theme: AI.

We spent the bulk of the period with lower-than-benchmark exposure to U.S. assets, preferring emerging markets and developed ex U.S. equities. Early in 2026, we moderated this positioning slightly. We also increased exposure to commodities during the period. Exposure to precious metals equities and commodities and tactical asset allocation were the primary drivers of outperformance. No major portfolio components detracted significantly from the benchmark.
