Figures quoted represent past performance, which is no guarantee of future results. Investment return and principal value of an investment will fluctuate so that an investor's shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance data quoted. Net asset value (NAV) is the value of one share of the fund excluding any sales charges. Returns for periods of less than one year are not annualized. Investor Class shares are sold without a front-end sales charge or contingent deferred sales charge.

2 For each fund with at least a three-year history, Morningstar calculates a Morningstar Rating™ based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a fund's monthly performance (including the effects of sales charges, loads, and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of funds in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars and the bottom 10% receive 1 star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages.) Past performance is no guarantee of future results.

3 The Lipper Mid-Cap Core Funds Average is an average of funds which invest at least 75% of their equity assets in companies with market capitalizations (on a three-year weighted basis) of less than 300% of the dollar weighted median market capitalization of the middle 1,000 securities of the S&P SuperComposite 1500 Index. These funds typically have an average price-to-earnings ratio, price-to-book ratio, and three-year sales-per-share growth value, compared to the S&P MidCap 400 Index. The total return of the Lipper Average does not include the effect of sales charges. You cannot invest directly in a Lipper Average.
