The aim is for your investment to reflect the performance of the Short IBOXX® ? SOVEREIGNS EUROZONE TOTAL RETURN INDEX (Index). The Index reflects the daily opposite performance of the IBOXX® ? SOVEREIGNS EUROZONE TOTAL RETURN Index (Underlying Index), plus a rate of interest. This means that 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 the rate at which banks in the Eurozone lend to each other overnight and a market rate for certain bond sale and repurchase (repo) transactions earned on the short positions.
