Strategy. In seeking to track the performance of the MSCI USA Gender Diversity Select Index ? (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 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 MSCI USA Gender Diversity Select Index (the Index) is designed to represent the performance of companies that exhibit a commitment towards promoting and maintaining a high level of gender diversity across the different levels within their organization, including their corporate board, executive and senior management, and workforce. The selection universe for the Index includes all constituents in the MSCI USA Index (the Parent Index), which is designed to measure the performance of the large- and mid-cap segments of the U.S. market. The Parent Index includes companies classified as United States companies by the Index Provider generally based on the company's country of incorporation and the primary listing of its securities. The Index incorporates certain gender diversity and environmental, social and governance (ESG) metrics developed by MSCI ESG Research (a subsidiary of the Index Provider (defined below)) to score and screen each security within the Parent Index. Companies in the Parent Index are first assigned an ESG Controversy Score, which provides an assessment of controversies concerning any negative environmental, social and/or governance impact of a company's operations, products and services. ESG Controversy Scores fall on a 0-10 scale, with 0 representing a company assessed as having involvement in very severe controversies. The Parent Index is screened to remove (i) companies with an ESG Controversy Score of 0 and (ii) companies not assigned an ESG Controversy Score. In addition, the Parent Index is also screened to remove companies with a Labor Rights Discrimination and Workforce Diversity Controversy score of 0 or 1, which are companies determined as having involvement in certain very severe or severe workforce diversity controversies. Factors affecting this evaluation include, but are not limited to, a history of involvement in discrimination- related legal cases, widespread or egregious instances of discrimination on the basis of sex, race, or ethnicity, resistance to improved practices, and workplace discrimination-related criticism and allegations by non-governmental organizations and/or other third-party observers. The remaining securities are each assigned an MSCI Gender Diversity Score based on two components: a Women Representation Score and a Diversity Management Score. The Women Representation Score reflects 75% of the weight of the MSCI Gender Diversity Score and evaluates each company based on the following criteria and the company's disclosure of such criteria: (i) percent/number of women on the board of directors, (ii) percent of women in executive management positions, (iii) percent of women in senior management positions, and (iv) percent of all employees who are women. The Diversity Management Score represents the remaining 25% of the weight of the MSCI Gender Diversity Score and evaluates each company based on the following criteria: (i) workforce diversity policies and senior management oversight of such policies; (ii) programs to help attract, retain and promote women in the workforce, including explicit quantitative recruitment targets and employee benefits; and (iii) ability to attract, retain and develop human capital based on its provision of benefits, training and development programs, and employee engagement. Companies are not eligible for inclusion in the Index if they have (i) no women serving on the board of directors and no women serving in executive management positions or (ii) a Women Representation Score of 3 or less (based on a 0-10 scale). For each GICS (Global Industry Classification Standard) sector, companies are selected for inclusion in the Index primarily in decreasing order of MSCI Gender Diversity Score until 50% of the free float adjusted market capitalization (calculated by multiplying the number of shares readily available in the market by the price of such shares) of the sector is reached. The selected securities are weighted by the product of their market capitalization weight in the Parent Index and the MSCI Gender Diversity Score. The weights are then distributed proportionally to sum to 100%. Sector weights in the Index are set equal to the corresponding sector weight in the Parent Index. To mitigate concentration risk, each security's weight in the Index is capped at 4.5%, and any weight exceeding this limit will be redistributed on a pro-rata basis to securities that do not exceed the 4.5% limit. The index is rebalanced quarterly, and changes are implemented at the end of February, May, August and November. As of August 31, 2025, a significant portion of the Fund comprised companies in the technology sector, although this may change from time to time. As of July 31, 2025, the Index comprised 228 securities. The Index is sponsored by MSCI, Inc. (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
