The aim is for the investment to reflect the performance of the ShortDAX® Index (Index) which provides the opposite performance of the DAX® Index (Underlying Index) plus a rate of interest. This means the level of the Index should rise when the Underlying Index falls and fall when the Underlying Index rises on a daily basis. The interest rate added to the 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. 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. A company?s readily available shares must be continuously traded and represent at least 10% of all readily available shares on the Stock Exchange.
