As of December 31, 2022, the market capitalization range for Russell 2500 Index was $6 million to $21.2 billion. Market capitalizations of companies within the Russell 2500 Index are subject to change. The Fund may invest up to 25% of its total assets in foreign securities, some of which may be issued by companies domiciled in emerging market countries. As an alternative to holding foreign stocks directly, the Fund may invest in U.S. dollar-denominated securities of foreign companies that trade on U.S. exchanges or in the over-the-counter market (including depositary receipts, such as American Depositary Receipts sponsored or unsponsored and Global Depositary Receipts, that evidence ownership in underlying foreign stocks). The Fund may invest in exchange-traded funds (ETFs), a type of pooled investment vehicle, in order to manage cash positions or seek exposure to certain markets or market sectors. The Fund may also invest in publicly traded real estate investment trusts (REITs). Investment decisions for the Fund are made primarily on the basis of fundamental research. The portfolio managers utilize information provided by, and the expertise of the investment advisers research staff in making investment decisions. The portfolio managers look for companies that, in their opinion, are high in quality or improving in quality. The portfolio managers take a long-term perspective when selecting companies and the quality focus typically leads them to companies benefitting from structural growth or structural change. Sought after company characteristics may include: a business model with identifiable competitive advantage(s)/barrier(s) to entry, a scalable market opportunity, a solid balance sheet, and a strong management team with a history of good capital allocation. Such companies typically exhibit high or improving returns on capital, strong free-cash-flow generation, and positive or inflecting earnings. The portfolio managers also employ a disciplined valuation framework in pursuit of attractive risk adjusted returns. The portfolio managers seek to manage investment risk by maintaining broad issuer and industry diversification among the Funds holdings, and by utilizing fundamental analysis of risk/return characteristics in securities selection. Securities may be sold if, in the opinion of the portfolio managers, the price moves above a fair level of valuation, the companys fundamentals deteriorate, or to pursue more attractive investment opportunities. The portfolio managers may also consider financially material environmental, social and governance (ESG) factors in evaluating an issuer. These considerations may be taken into account alongside other fundamental research in the investment selection process. Show less
