Mairs & Power Small Cap Fund 

The fund normally will invest at least 80% of its net assets (including borrowings for investment purposes) in U.S. common stocks issued by small cap companies. For this purpose, small cap companies are defined as companies whose market capitalization at the time of purchase is within the market capitalization range represented by companies in the S&P SmallCap 600 Total Return Index. The S&P SmallCap 600 Total Return Index is a widely used benchmark for small cap performance and is rebalanced continuously.
