The investment seeks investment results that correspond (before fees and expenses) generally to the price and yield performance of its underlying index, the FTSE Developed Europe 50% Hedged to USD Index (the "underlying index"). The underlying index is an equity benchmark for European countries, with approximately half of the currency exposure of the securities included in the underlying index "hedged" against the U.S. dollar on a monthly basis. The fund invests, under normal circumstances, at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in the securities and other instruments included in its underlying index.
