SPDR Portfolio Intermediate Term Corporate Bond ETF (SPIB) Exchange: NYSE ARCA

In seeking to track the performance of the Bloomberg Barclays U.S. Intermediate Corporate Bond 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 and in securities that the Adviser determines have economic characteristics that are substantially identical to the economic characteristics of the securities that comprise the Index. In addition, in seeking to track the Index, the Fund may invest in debt 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 Fund may use derivatives, including credit default swaps and credit default index swaps, to obtain investment exposure that the Adviser expects to correlate closely with the Index, or a portion of the Index, and in managing cash flows.The Index is designed to measure the performance of U.S. corporate bonds that have a maturity of greater than or equal to 1 year and less than 10 years. The Index is a component of the Bloomberg Barclays U.S. Corporate Index and includes investment grade, fixed-rate, taxable, U.S. dollar denominated debt with $300 million or more of par amount outstanding, issued by U.S. and non-U.S. industrial, utility, and financial institutions. Subordinated issues, securities with normal call and put provisions and sinking funds, medium-term notes (if they are publicly underwritten), 144A securities with registration rights, and global issues that are SEC-registered are included. Structured notes with embedded swaps or other special features, as well as private placements, floating- rate securities, and Eurobonds are excluded from the Index. The Index is rebalanced monthly, on the last business day of the month. As of August 31, 2019, a significant portion of the Fund comprised companies in the industrial and financial sectors, although this may change from time to time. As of August 31, 2019, there were approximately 3,982 securities in the Index, the dollar-weighted average maturity of the securities in the Index was 4.93 years and the modified adjusted duration of securities in the Index was approximately 4.28 years.The Index is sponsored by Bloomberg Index Services Limited (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.
