The investment seeks daily investment results, before fees and expenses, that correspond to two times (2x) the performance of the Bloomberg Natural Gas SubindexSM for a single day. The fund seeks to meet their investment objectives by investing normally in Natural Gas futures contracts. It may also invest in swaps if the market for a specific futures contract experiences emergencies (e.g., natural disaster, terrorist attack, or an act of God) or disruptions (e.g., a trading halt or a flash crash) or in situations where the Sponsor deems it impractical or inadvisable to buy or sell futures contracts (such as during periods of market volatility or illiquidity).
