The Fund invests at least 80 percent of its total assets, plus borrowings for investment purposes (if any), in the securities of the Solactive Global Hydrogen Index (the Underlying Index) and in American Depositary Receipts (ADRs) and Global Depositary Receipts (GDRs) based on the securities in the Underlying Index. Solely for purposes of complying with this policy, the Fund only views securities issued by Hydrogen Companies and Pre-Revenue Hydrogen Companies (both as defined below) as satisfying this criterion. The Funds 80 percent investment policy is non-fundamental and requires 60 days prior written notice to shareholders before it can be changed.
