The aim is for your investment to reflect the performance of the ShortDAX x2 Index (the "Reference Index") which provides two times the opposite performance of the DAX Index on a daily basis plus a rate of interest and minus borrowing costs. This means the level of the Reference Index should rise at double the rate the DAX Index falls and fall at double the rate the DAX Index rises. The interest rate added to the Reference Index level is based on three times the rate at which banks in the Eurozone lend to each other on an overnight basis (as calculated by the European Central Bank). Further information on the Reference Index is contained under "General Description of the Reference Index".
