The investment seeks to replicate, net of expenses, the returns of twice (2x) the daily performance of the S&P 500 VIX Short-Term Futures index. The index was designed to provide investors with exposure to one or more maturities of futures contracts on the VIX, which reflects implied volatility of the S&P 500 Index at various points along the volatility forward curve. The ETNs are linked to a multiple (2x) of the daily return of the index and do not represent an investment in the VIX.
