The Fund attempts to maintain exposure to carbon credit futures that are substantially the same as those included in the Index and to exceed the performance of the Index through direct or indirect investment in investment grade debt instruments. The Index is designed to measure the performance of a portfolio of futures contracts on carbon credits issued under the European Union Emissions Trading System cap and trade regime (carbon credit futures). The Index includes only carbon credit futures that mature in December of the next one to two years. The Fund will utilize a subsidiary (the Subsidiary) for purposes of investing in carbon credit futures. The Subsidiary is a corporation operating under Cayman Islands law that is wholly-owned and controlled by the Fund. The Subsidiary is advised by the Adviser. The Fund may invest up to 25% of its assets in the Subsidiary. The Subsidiary has the same investment objective as the Fund and will follow the same investment policies and restrictions as the Fund. Except as noted, for purposes of this Prospectus, references to the Funds investment strategies and risks include those of its Subsidiary, and references to the Fund include the Subsidiary.
