(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, SSGA Funds Management, Inc. (SSGA FM or the Adviser), the investment adviser to the Fund, either 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, as determined by the Adviser to be in the best interest of the Fund in pursuing its objective. 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, in seeking to track the Index, the Fund may invest in equity securities that are not included in the Index. The Fund may also invest in cash and cash equivalents or money market instruments (including money market funds advised by the Adviser) for cash management purposes. In seeking to track the Index, the Fund's assets may be concentrated in an industry or group of industries, but only to the extent that the Index concentrates in a particular industry or group of industries. Futures contracts (a type of derivative instrument) may be used by the Fund in seeking performance that corresponds to the Index and in managing cash flows. The Index is designed to measure the performance of securities meeting certain sustainability criteria (criteria related to ESG factors), while maintaining similar overall industry group weights as the S&P SmallCap 600 Index. The S&P SmallCap 600 Index measures the performance of the small-capitalization segment of the U.S. equity market. Securities eligible for inclusion in the Index comprise all constituents of the S&P SmallCap 600 Index except for: Companies that meet any of the following Business Involvement Exclusions, based on revenue levels as determined by S&P Global, Inc. (an affiliate of the Index Provider (defined below)): Companies that derive any amount of revenue from manufacturing tobacco products, 5% or greater of their revenue from supplying products and services essential for the tobacco industry, or 5% or greater of their revenue from the distribution and/or retail sale of tobacco products; Controversial Weapons Companies, defined as companies that derive any amount of revenue from (i) manufacturing components intended solely for use in the production of and are essential for the functioning of anti-personnel mines, biological and chemical weapons, blinding laser weapons, cluster munitions, depleted uranium, incendiary weapons and nuclear weapons (collectively, Controversial Weapons), or (ii) products and/or services related to the sale, supply and transfer of Controversial Weapons; Companies that derive 5% or greater of their revenue from the extraction and/or production of fossil fuels from oil/tar sands; Companies that (i) derive any amount of revenue from the manufacturing of small arms weapons for civilian or non-civilian use, or key components of assault weapons; or (ii) derive 5% or greater of their revenue from the retail or distribution of small arms weapons for civilian customers; Companies that derive 10% or greater of their revenue from (i) manufacturing, assembling, selling and transporting weapons, equipment, structures, and vehicles, or providing vehicle and equipment maintenance services and logistics and operations support, specifically for the purposes of warfare , or (ii) manufacturing and selling military weapon-related products; or Companies that derive 5% or greater of their revenue from (i) owning and/or operating coal mines that engage in thermal coal mining or (ii) electricity generation using coal powered plants. Companies that hold 25% or greater ownership stakes (as determined by S&P Global, Inc.) in: Companies that derive any amount of revenue from manufacturing tobacco products; Controversial Weapons Companies; or Companies that derive any amount of revenue from the manufacturing of small arms weapons for civilian and non-civilian use, or key components of assault weapons. Companies that are classified by Sustainalytics to be non-compliant with the United Nations Global Compact (UNGC) principles (Non-Compliant UNGC Companies). Non-Compliant UNGC Companies are (i) companies found to have been responsible for egregious and severe violations of commonly accepted international norms related to human rights, labor rights, the environment and business ethics, or (ii) companies deemed to facilitate third parties in human rights violations due to their involvement in certain weapons with disproportional and/or non-discriminatory impact on citizens and society; Companies that (i) have an S&P Global ESG Score that falls within the worst 25% of scores from each Global Industry Classification Standard (GICS) industry group in the underlying universe of companies eligible for inclusion in the Index (the Investment Universe), or (ii) fall within the worst 10% of scores in the Investment Universe. If less than 75% of the weight of the Investment Universe remains eligible, constraints (i) and (ii) will be relaxed; or Companies that do not have (i) coverage for determining tobacco-, controversial weapons-, oil sands-, small arms-, military weapons- and thermal coal-related involvement or compliance with UNGC principles; or (ii) an S&P Global ESG Score. S&P Global ESG Scores are assigned by S&P Global, Inc., using its Corporate Sustainability Assessment, which is an annual evaluation of a company, based on ESG factors that S&P Global, Inc. determines are financially material to the company, relative to its industry peer companies. After implementing the exclusion criteria described above, the remaining companies are then ranked based on their S&P Global ESG Score. For each GICS industry group, companies are selected for inclusion in the Index primarily in decreasing order of S&P Global ESG Score until approximately 75% of the float adjusted market capitalization of the industry group is reached. The Index is float-adjusted market capitalization weighted. A company's float-adjusted market capitalization is calculated by multiplying the number of shares readily available in the market by the price of such shares. The Index is reconstituted and rebalanced annually on the last business day in April based on information as of the last trading date in March. In addition, companies will be removed from the Index (i) on the last business day of July, October and January, if found to meet a Business Involvement Exclusion as of the last business day of the previous month, or (ii) on the third Friday of March, June, September and December if found to be a Non-Compliant UNGC Company as of the last business day of the previous month. In addition, between Index rebalances, Index constituents may be removed from the Index for their involvement in economic crime and corruption, fraud, illegal commercial practices, human rights abuses, labor disputes, workplace safety catastrophic accidents, environmental disasters, and certain other activities associated with environmental, social and governance risks. Any companies removed from the Index on account of such activities are not eligible for inclusion in the Index until one full calendar year from the next rebalancing of the Index. As of August 31, 2025, a significant portion of the Fund comprised companies in the financial and industrial sectors, although this may change from time to time. As of July 31, 2025, the Index comprised 411 stocks. The Index is sponsored by S&P Dow Jones Indices LLC (the Index Provider), which is not affiliated with the Fund or the Adviser. The Index Provider determines the composition of the Index, relative weightings of the securities in the Index and publishes information regarding the market value of the Index. Show less
