The fund seeks to achieve its objective by investing primarily in a diversified portfolio of income-producing common stocks of mid-capitalization companies that the manager believes demonstrate favorable prospects for total return. It invests at least 80% of its net assets in the securities of mid-capitalization companies which for purposes of this fund typically are companies with market capitalizations similar to those of issuers included in the Russell Midcap® Index over the last 13 months at the time of acquisition.
