Strictly in accordance with its guidelines and mandated procedures, Keefe, Bruyette & Woods, Inc. and Nasdaq, Inc. (KBW Nasdaq or the Index Provider) compile, maintain and calculate the Underlying Index, which is a modified-dividend yield-weighted index of companies principally engaged in the business of providing financial services and products, as determined by the Index Provider. The Underlying Index is designed to track the performance of financial companies, which may include business development companies and mortgage real estate investment trusts, with competitive dividend yields that are publicly-traded in the U.S. As of October 31, 2025, the Underlying Index was comprised of 40 securities with market capitalizations ranging from $413.7 million to $36.4 billion. The Fund employs a full replication methodology in seeking to track the Underlying Index, meaning that the Fund generally invests in all of the securities comprising the Underlying Index in proportion to their weightings in the Underlying Index. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries. As of August 31, 2025, the Fund had significant exposure to the financials sector. The Funds portfolio holdings, and the extent to which it concentrates its investments, are likely to change over time. Show less
