SPDR ICE Preferred Securities ETF (PSK) Exchange: NYSE ARCA

In seeking to track the performance of Wells Fargo Hybrid and Preferred Securities Aggregate 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”) 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, 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 is a modified market capitalization weighted index designed to measure the performance of non-convertible preferred stock and securities that are functionally equivalent to preferred stock, including, but not limited to, depositary preferred securities, perpetual subordinated debt and certain securities issued by banks and other financial institutions that are eligible for capital treatment with respect to such instruments akin to that received for issuance of straight preferred stock (collectively, “Preferred Securities”). Preferred Securities generally pay fixed rate distributions and typically have “preference” over common stock in the payment of distributions and the liquidation of a company's assets — preference means that a company must pay distributions on its Preferred Securities before paying dividends on its common stock, and the claims of Preferred Securities holders are ahead of common stockholders' claims on assets in a corporate liquidation. The Index includes Preferred Securities that meet the following criteria: (i) are non-convertible; (ii) have a par amount of $25; (iii) are listed on the New York Stock Exchange or NYSE Arca, Inc. (“NYSE Arca”); (iv) maintain a minimum par value of $250 million; (v) are U.S. dollar denominated; (vi) are rated investment grade by one of Moody's Investors Service, Inc. or Standard & Poor's Financial Services, LLC ratings services; (vii) are publicly registered or exempt from registration under the Securities Act of 1933; and (viii) have a minimum monthly trading volume during each of the last six months of at least 250,000 trading units. The Index does not include auction rate preferred securities, convertible preferred shares, securities subject to sinking fund provisions, shares in closed-end funds, municipal securities, or repackaged securities linked to a security, a basket of securities or an index. The Index is rebalanced monthly, on the final NYSE Arca trading day of each month. Issuers of Preferred Securities may be either U.S. based or foreign. As of August 31, 2019, a significant portion of the Fund comprised companies in the financial and utilities sectors, although this may change from time to time. As of August 31, 2019, the Index comprised 163 Preferred Securities.The Index is sponsored by Wells Fargo & Company (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.
