The investment seeks investment results that correspond generally to the price and yield (before the fund's fees and expenses) of an equity index called the ISE Global Engineering and Construction(TM) Index. The fund normally invests at least 90% of assets in common stocks that comprise the index or in depositary receipts representing securities in the index. The index provides a benchmark for investors interested in tracking public companies throughout the world that are active in the engineering and construction industries, based on analysis of the products and services offered by those companies. The fund is non-diversified.
