Fund Description: SPDR SSGA Gender Diversity Index ETF is an exchange-traded index fund or Index ETF which is a separate portfolio of the SPDR Series Trust, an open-end investment management company. INVESTMENT OBJECTIVE: The SPDR SSGA Gender Diversity Index ETF seeks to provide investment results that, before expenses, correspond generally to the total return performance of the SSGA Gender Diversity Index. INDEX DESCRIPTION: The SSGA Gender Diversity Index is designed to track the performance of US large-capitalization companies that are leaders within their respective industry sectors in advancing women through gender diversity on their boards of directors and in senior leadership positions. The Index constituents are a subset of the largest 1,000 U.S. stocks based on market capitalization listed on a U.S. national securities exchange that have a trailing six-month average daily trading volume of at least 250,000 shares at the time of inclusion. This subset serves as the initial universe of eligible securities for the Index. Companies are ranked within each sector by the following three gender diversity ratio-based criteria: (i) ratio of female executives and female members of the board of directors to all executives and members of the board of directors; (ii) ratio of female executives to all executives; (iii) ratio of female executives excluding executives who are members of the board of directors to all executives excluding executives who are members of the board of directors. The Index is weighted by float-adjusted market capitalization at each annual rebalance. FUND STRATEGY: In seeking to track the performance of the Index the Fund employs a sampling strategy, which means that the Fund is not required to purchase all of the securities represented in the Index. Instead, the Fund 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 quantity of holdings in the Fund will be based on a number of factors, including asset size of the Fund. Based on its analysis of these factors the Adviser may invest the Fund’s assets in a subset of securities in the Index or may invest the Fund’s assets in substantially all of the securities represented in the Index in approximately the same proportions as the Index. Under normal market conditions, the Fund generally invests substantially all, but at least 80%, of its total assets in the securities comprising the Index. In addition, the Fund may invest in equity securities that are not included in the Index (including common stock, preferred stock, depositary receipts and shares of other investment companies), cash and cash equivalents or money market instruments, such as repurchase agreements and money market funds. Futures contracts may be used by the Fund in seeking performance that corresponds to its Index and in managing cash flows. FUND MANAGEMENT: SSgA FM serves as the investment adviser to the Fund.
