The investment seeks daily investment results before fees and expenses of 300% of the inverse (or opposite) of the daily performance of the ICE U.S. Treasury 7-10 Year Bond Index. The fund invests in swap agreements, futures contracts, short positions or other financial instruments that, in combination, provide inverse or short leveraged exposure to the index equal to at least 80% of the fund's net assets (plus borrowing for investment purposes). The index is a market value weighted index that includes publicly issued U.S. Treasury securities that have a remaining maturity of greater than or equal to seven years and less than ten years. It is non-diversified.
