Fund Description: 500 Fossil Fuel Reserves Free ETF, formerly SPDR S&P 500 Fossil Fuel Free 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 500 Fossil Fuel Reserves Free ETF seeks to provide investment results that, before expenses, correspond generally to the total return performance of the S&P 500 Fossil Fuel Free Index. INDEX DESCRIPTION: The S&P 500 Fossil Fuel Free Index is designed to measure the performance of companies in the S&P 500 Index that are fossil fuel free, which are defined as companies that do not own fossil fuel reserves. Fossil fuel reserves are defined as economically and technically recoverable sources of crude oil, natural gas and thermal coal but do not include metallurgical or coking coal, which are used in connection with steel production. The Index is a subset of the S&P 500 Index Index, which serves as the initial universe of eligible securities for the Index. In constructing the Index, the initial universe is screened in an effort to exclude companies with any ownership of fossil fuel reserves, including for third-party and in-house power generation, as determined by publicly available information, such as annual reports and other company publications. The Index is weighted by float-adjusted market capitalization. The Index is rebalanced quarterly. 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. FUND MANAGEMENT: SSgA FM serves as the investment adviser to the Fund.
