Investment Objective

This Fund seeks growth of capital over the long-term.

Investment Overview

The investment seeks growth of capital over the long-term. The fund invests primarily in equity securities of mid-capitalization companies. It normally invests at least 80% of its net assets in a broadly diversified portfolio of common stocks of mid-cap companies whose earnings the subadvisers expect to grow at a faster rate than the average company. The subadvisers currently define "mid-cap" companies as those whose market capitalizations at the time of purchase fall within the market capitalization range of companies included in either the S&P MidCap 400® Index or the Russell Midcap® Growth Index.
