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 designed to track the performance of companies primarily engaged in U.S. property and casualty insurance activities, as determined by the index provider. The fund is non-diversified.
