Strategy. The Fund invests primarily in equity securities issued by U.S. companies. The Fund currently anticipates that substantially all of its portfolio will consist of securities of companies with large and mid-sized market capitalizations. The Fund's investment adviser generally defines a large cap company to have a market capitalization in excess of $25 billion and a mid-sized company to have a market capitalization greater than $1 billion, up to $25 billion. The Fund may invest up to 25% of its net assets in foreign securities.

The Fund's investment adviser generally defines a large cap company to have a market capitalization in excess of $25 billion and a mid-sized company to have a market capitalization greater than $1 billion, up to $25 billion. The Fund may invest up to 25% of its net assets in foreign securities. Foreign securities are securities issued by issuers that are organized under the laws of a foreign country or that have a substantial portion of their operations or assets in a foreign country or countries, or that derive a substantial portion of their revenue or profits from businesses, investments or sales outside of the United States. The Fund may also invest in foreign securities that are represented in the United States securities markets by American Depositary Receipts ("ADRs") or similar depository arrangements. The Fund's foreign debt investments can be denominated in U.S. dollars or in foreign currencies. Debt securities issued by a foreign government may not be supported by the "full faith and credit" of that government. The Fund may also invest in privately placed securities, including in third-party private funds ("Private Funds") that themselves invest in equity securities of privately held companies subject to applicable limits under the 1940 Act. In pursuing its investment objective, the Fund seeks out securities that, in the investment adviser's opinion, offer the best opportunities for growth. The Fund's investment adviser typically considers the company's financial soundness, earnings and cash flow forecast and quality of management. The Fund's investment adviser seeks to lower the risks of investing in stocks by using a "top-down approach" of diversification by company, industry, sector, country and currency and focusing on macro-level investment themes.
