The aim is for the investment to reflect the performance of the ShortDAX® x2 Index (Index) which provides two times the opposite performance of the DAX® Index (Underlying Index) on a daily basis plus a rate of interest. This means the level of the Index should rise at double the rate the Underlying Index falls and fall at double the rate the Underlying Index rises. The interest rate added to the 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). The Underlying Index reflects the performance of the shares of 30 of the largest and most actively traded German companies (from any business sector) on the Frankfurt Stock Exchange. To be included on the Underlying Index, a company?s readily available shares must be continuously traded and represent at least 10% of all readily available shares on the Frankfurt Stock Exchange.
