The investment seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of the SSGA Small Cap Index that tracks the performance of small capitalization exchange traded U.S. equity securities. The fund generally invests substantially all, but at least 80%, of its total assets in the securities comprising the index. It may purchase a subset of the securities in the index in an effort to hold a portfolio of securities with generally the same risk and return characteristics of the index. The fund is non-diversified.
