| Factors Affecting Performance [Text Block] | HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? U.S. mid-cap equities rose modestly during the trailing 12 months, against a backdrop of volatile market swings, strong enthusiasm for AI, and continued concentration in a narrow group of market leaders. While tariff-related uncertainty periodically unsettled markets, sentiment improved as the period progressed. Sector and stock-level dispersion remained elevated within the mid-cap segment. The Fund rose but trailed its benchmark, the Russell 1000 Index. The Fund’s consumer discretionary holdings contributed most to absolute performance, while energy and financials also added positively. In contrast, health care and basic materials were the most notable detractors from performance, with telecommunications also weighing on results.

| Factors Affecting Performance [Text Block] | HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? Emerging markets rose during the trailing 12 months, against a backdrop of volatile market conditions and continued strength in technology-related areas, though returns were increasingly dispersed across countries and sectors. Technology-driven gains in markets such as Korea and Taiwan, alongside strong performance in parts of Latin America, contrasted with softer results in countries including India and Indonesia. At the sector level, information technology, materials, industrials, and financials were the strongest performers, while no sector posted negative performance over the period. The Fund rose during the period and outperformed the MSCI Emerging Markets Index. Financials, information technology, and industrials were the largest contributors to absolute performance, while consumer discretionary and consumer staples also contributed positively. At the country level, Korea, China, and Brazil were the largest contributors to absolute performance, while Kazakhstan, South Africa, and Saudi Arabia weighed on results.

| Factors Affecting Performance [Text Block] | HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? U.S. small-cap equities rose during the trailing 12 months. Markets moved higher through year-end and into early 2026, supported by resilient economic data and stable interest-rate expectations. Small caps underperformed for much of the period, but rebounded to start 2026 as leadership broadened beyond large-cap technology toward more cyclical areas and smaller-cap stocks showed relative resilience. Dispersion across sectors and individual stocks remained elevated. The Fund rose but trailed its benchmark, the Russell 2000 Index. The Fund’s industrials and consumer discretionary holdings contributed most to absolute performance, while financials also added positively. In contrast, basic materials and real estate were the only sectors to detract from absolute performance over the period.

International small-cap equities rose during the trailing 12 months, as markets navigated periods of elevated volatility, improving sentiment, and a gradual broadening in leadership beyond the narrowest areas of the market. The backdrop was supported by stabilizing interest rate expectations and improving risk appetite, though returns remained uneven across countries, sectors, and individual companies. Against this backdrop, the Fund rose and outperformed the MSCI World ex-USA IMI Index. The Fund’s materials, financials, consumer discretionary, and industrials holdings contributed most to absolute performance, while no sector detracted from performance over the period. At the country level, Japan, Ireland, and the United Kingdom were among the largest contributors to performance, while Denmark was a modest detractor.

| Factors Affecting Performance [Text Block] | HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? International equity markets rose during the trailing 12 months, supported by improving risk appetite and strength across major regions, particularly in Europe, as leadership broadened beyond a narrow group of large-cap growth stocks. The period was marked by elevated volatility and shifting sentiment, but non-U.S. markets benefited from increased investor interest as global equity performance became less concentrated in the U.S. Value outperformed growth, and cyclical areas of the market contributed meaningfully to returns. The Fund rose and outperformed the MSCI EAFE Index. The Fund’s financials, information technology, and consumer discretionary holdings were the largest contributors to absolute performance, while no sector detracted from absolute performance over the period, reflecting strength across cyclical and economically sensitive areas of the market. At the country level, Japan, the United Kingdom, and Korea were among the largest contributors to performance, while no country materially detracted from performance over the period.
