Gross Expense Ratio is the fund’s total operating expense ratio from the fund’s most recent prospectus. Net Expense Ratio reflects the reduction of expenses from fee waivers and reimbursements. Elimination of these reductions will result in higher expenses and lower performance. These reductions will continue until at least December 31, 2014.
Performance data shown represents past performance and is no guarantee of future results. Investment return and principal value fluctuate so your shares, when sold, may be worth more or less than the original cost; current performance may be lower or higher than quoted.
Performance results reflect any applicable expense subsidies and waivers in effect during the periods shown. Without such subsidies and waivers the fund's performance results would be less favorable. All results are historical and assume the reinvestment of dividends and capital gains.
Class A shares ("A") results include the maximum sales charge.
Important Risk Considerations

Stock markets and investments in individual stocks are volatile and can decline significantly in response to issuer, market, economic, political, regulatory, geopolitical, and other conditions.
Investments in mid-cap companies can be more volatile than investments in larger companies.
Investments in growth companies can be more sensitive to the company's earnings and more volatile than the stock market in general.
Please see the prospectus for further information on these and other risk considerations.
