Heartland Mid Cap Value Fund Investor Class

The investment seeks long-term capital appreciation and modest current income.

Under normal circumstances, at least 80% of the fund's net assets are invested in common stocks and other equity securities of mid-capitalization companies. It invests primarily in a concentrated number (generally 40 to 60) of mid-capitalization common stocks selected on a value basis and whose current market prices, in Heartland Advisors' judgment, are undervalued relative to their intrinsic value.

Value stocks can perform differently than other types of stocks and can continue to be undervalued by the market for long periods of time. The securities of smaller, less well-known companies can be more volatile than those of larger companies. Stock markets are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments. These risks may be magnified in foreign markets. Additional risk information for this product may be found in the prospectus or other product materials, if available.
