The investment seeks to track the investment results (before fees and expenses) of the KBW Nasdaq Bank Index (the underlying index). The fund generally will invest at least 90% of its total assets in the securities that comprise the underlying index. The underlying index is a modified-market capitalization-weighted index of companies primarily engaged in U.S. banking activities, as determined by the index provider. The underlying index is designed to track the performance of large national U.S. money centers, regional banks, and thrift institutions that are publicly traded in the U.S. The fund is non-diversified.
