Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in equity securities. Equity securities may include common stocks, preferred stocks, securities convertible into common or preferred stocks, rights, and warrants, of issuers of any size. The Fund typically invests most of its assets in equity securities of U.S. companies, but may invest in foreign securities and American Depositary Receipts (ADRs), including emerging market securities. The Fund generally will not invest more than 30% of its total assets in foreign securities. The Fund may at times have significant exposure to one or more industries or sectors. The Fund may hold a portion of its assets in cash or cash equivalents. Wellington Management seeks long-term total returns in excess of the broad market by investing in a select number of high quality, reasonably-valued companies that have demonstrated the willingness to return value to shareholders. The investment process stresses security selection based on bottom-up fundamental research to identify attractively valued stocks that have the potential for significant longer-term rewards. Wellington Managements investment philosophy is based on the premise that investing in high quality companies with superior prospects for dividend growth, and the fundamental strength to support that growth in the future, can provide superior long-term returns. Wellington Management typically sells a security when it achieves its price target or when it no longer exhibits superior upside return versus downside risk. Show less
