As of December 31, 2025 , the range of market capitalizations of the Dow Jones U.S. Small-Cap Total Stock Market Index was $ 28.23 million to $ 34.789 billion. As of December 31, 2025 , the range of market capitalizations of the S&P SmallCap 600 Index was $ 310.25 million to $ 9.219 billion. These capitalization ranges will change over time. The Fund may continue to hold securities of a portfolio company that subsequently drops below or outgrows the capitalization range. Because of this, the Fund may have less than 80% of its net assets in stocks of U.S. small-capitalization companies at any given time. Frontier Capital Management Co., LLC (Frontier or the Subadviser) utilizes and draws support from a team of investment professionals to identify opportunities and conduct fundamental research. Through fundamental bottom-up research Frontier seeks long-term capital appreciation by investing in small-capitalization companies that it believes have above-average earnings growth potential and are available at reasonable valuations.
