The Fund normally invests in common stocks of companies having market capitalizations that rank among the top 1,000 U.S. listed companies. The Fund may invest up to 20% of its assets in dollar-denominated stocks of foreign companies (including depositary receipts). The Fund also may invest in stocks of mid-cap companies and in publicly traded real estate investment trusts (REITs). Through investment in high quality companies, the Funds subadviser seeks to build a portfolio that may participate in rising markets while minimizing participation in declining markets. Quality is determined by analysis of a companys financial statements and is measured by a companys demonstrated ability to consistently grow earnings over the long-term. High quality companies typically have strong balance sheets, sustainable cash flow, enduring competitive advantages, long product cycles, and stable demand over a business cycle, among other characteristics. The subadviser may use financial quality rankings provided by nationally recognized rating services as additional information. The subadviser is responsible for fundamental analysis and security selection, incorporating environmental, social and governance (ESG) information provided by ESG analysts at Calvert Research and Management (Calvert), with which the subadviser is affiliated. The subadviser typically favors high quality companies it believes to have sustainable above-average earnings growth potential and to be trading below intrinsic value. Sustainable earnings growth potential is determined by fundamental analysis of a companys financial trends and management; products and services; industry position and conditions; and other factors. The subadviser seeks to invest in companies that manage ESG risk exposures adequately and that are not exposed to excessive ESG risk through their principal business activities. Companies are analyzed by Calverts ESG analysts using The Calvert Principles for Responsible Investment (included as the Appendix to this Prospectus), a framework for considering ESG factors. Each company is evaluated relative to an appropriate peer group based on material ESG factors as determined by Calvert. The subadviser seeks to manage individual security risk through analysis of each securitys risk/reward potential and to manage portfolio risk by constructing a diversified portfolio of what they believe to be attractively valued growth stocks. The subadviser may sell a security when its fundamentals deteriorate, when its valuation is no longer attractive, when other securities are identified to displace a current holding, or if it no longer meets the Funds ESG criteria.
