The investment seeks to provide investors with exposure to the daily change in the price of dry bulk freight futures, before expenses and liabilities of the fund. The fund seeks to achieve its investment objective by investing substantially all of its assets in the Freight Futures currently constituting the Benchmark Portfolio. It tracks the performance of a portfolio consisting of a three-month strip of the nearest calendar quarter of futures contracts on specified indexes (each a "reference index") that measure rates for shipping dry bulk freight. The three reference indexes are Capesize 5TC Index, Panamax 4TC Index and Supramax 6TC Index.
