SPDR S&P North American Natural Resources ETF (NANR) Exchange: NYSE ARCA

In seeking to track the performance of the S&P BMI North American Natural Resources 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 (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 (including money market funds advised by the Adviser). In seeking to track the Index, the Fund's assets will generally be concentrated in an industry or group of industries to the extent that the Index concentrates in a particular industry or group of industries.The Index comprises publicly traded large- and mid-capitalization U.S. and Canadian companies in the natural resources and commodities businesses that meet certain investability requirements and are classified within the subindustries of one of three natural resources categories: energy, metals & mining or agriculture. The Index is a sub-set of the S&P Global LargeMidCap Commodity and Resources Index (the “Parent Index”), which serves as the initial universe of eligible securities for the Index. The Parent Index consists of U.S. and foreign publicly traded large- and mid-cap companies in the natural resources and commodities businesses that are classified within the sub-industries of the energy, metals & mining or agriculture categories, have a minimum float-adjusted market capitalization of $1 billion and have a minimum three-month average daily value traded of $5 million. The Index consists of companies comprising the Parent Index that are domiciled in and publicly traded principally in the U.S. or Canada. Each natural resources category includes companies classified within specific Global Industry Classification Standard (GICS) sub-industries according to the company's principal business activity. The energy category consists of companies classified in the following sub-industries: coal & consumable fuels; integrated oil & gas; oil & gas exploration & production; oil & gas refining & marketing; and oil & gas equipment & services. The metals & mining category consists of companies classified in the following sub-industries: aluminum; diversified metals & mining; steel; copper; gold; precious metals & minerals; and silver. The agriculture category consists of companies classified in the following sub-industries: agricultural products; fertilizers & agricultural chemicals; forest products; paper packaging; paper products and Timber real estate investment trusts. At each quarterly Index rebalancing, the combined weight of securities of companies in the energy, metals & mining and agriculture categories are set at 45%, 35% and 20%, respectively. The Index uses a “modified market capitalization” weighting scheme, which means that modifications are made to the market capitalization weights, if required, to conform to requirements applicable to a “regulated investment company” under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), and reduce single-stock concentration. Index constituents are weighted within each natural resources category proportionally to their float-adjusted market capitalization subject to individual security weights limits. Market capitalization and liquidity criteria are subject to change on an annual basis according to market conditions. The Index is rebalanced quarterly. The Index is “float-adjusted,” meaning that only those shares publicly available to investors are included in the Index calculation. As of November 30, 2019, the Index comprised 48 securities.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.
