The Funds investment focus is on mid-cap growth companies, which are companies whose market capitalization is generally within the market capitalization range of the companies represented in the Russell Midcap Growth Index at time of purchase, although the Fund may invest in companies outside this range. Under normal circumstances, the Fund invests at least 80% of its net assets in mid-cap growth companies.
