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