Strategy. In seeking to track the performance of the Bloomberg U.S. Government Inflation-Linked 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.

(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. 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. The Index is designed to measure the performance of the inflation protected public obligations of the U.S. Treasury, commonly known as TIPS. TIPS are securities issued by the U.S. Treasury that are designed to provide inflation protection to investors. The Index includes publicly issued TIPS that have at least 1 year remaining to maturity on the Index rebalancing date, with an issue size equal to or in excess of $500 million. Bonds must be capital-indexed and linked to an eligible inflation index. The securities must be denominated in U.S. dollars and pay coupon and principal in U.S. dollars. The notional coupon of a bond must be fixed or zero. Bonds must settle on or before the Index rebalancing date. The securities in the Index are updated on the last business day of each month. As of July 31, 2025, there were 48 securities in the Index. 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. Show less
