The Fund seeks to track the investment results of the Dow Jones U.S. Real Estate Capped Index (the Underlying Index), which measures the performance of the real estate sector of the U.S. equity market, as defined by S&P Dow Jones Indices LLC (the Index Provider or SPDJI). The Underlying Index uses a capping methodology to limit the weight of the securities of any single issuer (as determined by SPDJI) to a maximum of 10 percent of the Underlying Index. Additionally, the Underlying Index constrains at each quarterly review: (i) the weight of any single issuer to a maximum of 10 percent, and (ii) the aggregate weight of all issuers that individually exceed 4.50 percent of the index weight to a maximum of 22.50 percent. Between scheduled quarterly index reviews, the Underlying Index is rebalanced at the end of any day on which all issuers that individually constitute more than 5 percent of the weight of the Underlying Index constitute more than 25 percent of the weight of the Underlying Index in the aggregate. In implementing this capping methodology, SPDJI may consider two or more companies as belonging to the same issuer where there is reasonable evidence of common control.
