The aim is for your investment to reflect the performance of the S&P 500 2x Leveraged Daily Index (the "Reference Index") which provides two times the performance of the S&P 500 Index on a daily basis less a rate of interest. This means that the level of the Reference Index should rise and fall at double the rate of the S&P 500 Index. The interest rate taken from the Reference Index level is based on the rate at which banks in London lend U.S. dollars to each other overnight. Further information on the Reference Index is contained under "General Description of the Reference Index".
