The fund defines small- and mid-cap companies as companies whose market capitalization falls below the maximum market capitalization in the Russell Midcap Index, MSCI USA Mid Cap Index, or MSCI World Mid Cap Index (after systematically removing any companies that cannot reasonably be considered a small- or mid-cap company from the high end of the range of each index). The market capitalizations of the companies in the indexes change over time and the indexes are periodically reconstituted to ensure that they continue to accurately reflect the small- and mid-cap equity markets. As of December 31, 2025, the largest market capitalization represented across these indexes (after removing any outlier companies) was $98 billion. The fund invests primarily in U.S. equity securities. The fund may select stocks with either growth or value characteristics, subject to overall risk controls and desired portfolio characteristics. The portfolio is typically constructed in a bottom up manner, an approach that focuses more on evaluations of individual stocks than on analysis of overall economic trends and market cycles. The funds adviser analyzes various metrics, such as returns on equity, capital expenditure, projected growth rates, and price-to-earnings, price-to-cash flows, and price-to-book ratios. Stocks are also evaluated on relative valuation, profitability, stability, earnings quality, management capital allocation actions, and indicators of near-term appreciation potential when compared with other stocks within the relevant investing universe. Sector allocations are largely the result of the funds focus on stock selection. At times, the fund may have a significant portion of its assets invested in the same economic sector. Show less
