Past performance is not a reliable indicator or guarantee of future results. Current performance may be higher or lower than the performance data quoted. Returns shown include the reinvestment of all distributions. Returns shown at net asset value do not reflect the current maximum sales charge, had the sales charge been included, returns would have been lower. The investment return and principal value of an investment will fluctuate so that shares, on any given day or when redeemed, may be worth more or less than the original cost.

Market Capitalization Breakdown - Morningstar separates stock portfolio holdings into five market-capitalization groups: Giant, Large, Mid, Small, and Micro. Of the 5000 largest domestic stocks in their equities database, the top 1% are categorized as Giant, the next 4% are Large, the next 15% are Mid, the next 30% are Small, and the remaining 50% are Micro. Stocks outside of the largest 5000 are also classified as Micro.
Weighted Average Market Cap - The average market capitalization of all companies held in the portfolio with each company weighted according to its percent held in the portfolio. The result is based upon a weighted average of the securities held in the fund.
P/B Ratio - A ratio that helps determine whether a stock is undervalued or overvalued. It is calculated by dividing a stock's price per share by its book value per share. The result is based upon a weighted average of the securities held in the fund.
P/E Ratio - Is the weighted average of each holding's P/E ratio (price of a stock divided by its earnings per share). The result is based upon a weighted average of the securities held in the fund.
Portfolio Turnover - This is a measure of the Fund’s trading activity which is computed by taking the lesser of purchases or sales divided by average monthly market value, excluding short-term investments. The resulting percentage represents the percentage of the portfolio’s holdings that have changed over the past year.
