The Underlying Index is designed to track the performance of small- and mid-capitalization domestic equity REITs that have competitive dividend yields and are publicly-traded in the U.S. As of October 31, 2025, the Underlying Index was comprised of 27 securities with market capitalizations ranging from $410.6 million to $12.6 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 real estate sector. The Funds portfolio holdings, and the extent to which it concentrates its investments, are likely to change over time. Show less
