ProShares VIX Short-Term Futures

The investment seeks to provide investment results (before fees and expenses) that match the performance of the S&P 500 VIX Short-Term Futures Index. The fund intends to obtain exposure to its index by investing in futures contracts based on the Chicago Board Options Exchange (“CBOE”) Volatility Index. It also holds cash or cash equivalents such as U.S. Treasury securities or other high credit quality short-term fixed-income or similar securities (such as shares of money market funds, bank deposits, bank money market accounts, certain variable rate-demand notes and collateralized repurchase agreements) that may be used as margin for the futures contracts.
