[1] In prior prospectuses, the Fund compared its performance against the Dow Jones U.S. Real Estate Total Return Index. The Fund’s Adviser believes the Dow Jones Global Select REIT Total Return Net Index is a more appropriate and accurate index against which to compare the Fund’s investment strategies and, therefore, the Dow Jones Global Select REIT Total Return Net Index will replace the Dow Jones U.S. Real Estate Total Return Index as the Fund’s primary benchmark in future comparisons.
[2] The Morningstar Real Estate Category is generally representative of mutual funds that primarily invest in REITs of various types. REITs are companies that develop and manage real estate properties.
