Investment in mutual funds involves risk, including possible loss of principal invested. You could lose money on your investment in the Fund or the Fund could underperform because of the following risks: the market prices of stocks held by the Fund may fall; individual investments of the Fund may not perform as expected; and/or the Fund's portfolio management practices may not achieve the desired result. Prices of mid-cap stocks may respond to market activity differently from and can be more volatile than those of larger, more established companies. Mid-cap companies are more likely to have more limited product lines, fewer capital resources and less depth of management than larger companies. The Fund is non-diversified and may be more volatile than a diversified fund.
