SPDRR NUVEEN BARCLAYS CAPITAL BUILD AMERICA BOND ETF (BABS) Exchange: NYSE ARCA

DELISTED - In seeking to track the performance of the Barclays Build America 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, Nuveen Asset Management, LLC (“Nuveen Asset Management” or the “Sub-Adviser”), the investment sub-adviser to the Fund, 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.Under normal market conditions, the Fund generally invests substantially all, but at least 80%, of its total assets in the securities comprising the Index or in securities that the Sub-Adviser determines have economic characteristics that are substantially identical to the economic characteristics of the securities that comprise the Index. The Fund will provide shareholders with at least 60 days' notice prior to any material change in this 80% investment policy. In addition, 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 SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund).The Index is a subset of the Barclays Taxable Municipal Bond Index. The Index consists of all direct pay Build America Bonds that satisfy the rules of the Barclays Taxable Municipal Bond Index. The Barclays Taxable Municipal Bond Index represents securities that are taxable, dollar denominated, and issued by a U.S. state or territory, and (i) have at least one year to final maturity regardless of call features, (ii) have at least $250 million par amount outstanding, (iii) are rated investment grade (Baa3/BBB- or higher) by at least two of the following ratings agencies: Moody's Investors Service, Inc., Fitch Inc. or Standard & Poor's Financial Services, LLC (if only two of the three agencies rate the security, the lower rating is used to determine index eligibility, and if only one of the three agencies rates a security, the rating must be investment grade), (iv) are fixed rate, although it can carry a coupon that steps up or changes according to a predetermined schedule, (v) are dollar-denominated and non-convertible, and (vi) are publicly issued. However, Rule 144A securities with Registration Rights and Reg-S issues are included. As of September 30, 2014, there were approximately 193 issues included in the Index and the modified adjusted duration of securities in the Index was approximately 12.43 years.The Index is sponsored by Barclays, Inc. (the “Index Provider”) which is not affiliated with the Fund, the Adviser or the Sub-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.Build America Bonds are bonds issued by state and local governments to finance capital projects such as public schools, roads, transportation infrastructure, bridges, ports and public buildings, among others, pursuant to the American Recovery and Reinvestment Act of 2009 (the “Act”). Build America Bonds pay interest at rates that are expected to be competitive with rates typically paid by private bond issuers in the taxable fixed income market. Unlike investments in most other municipal securities, interest received on Build America Bonds is subject to federal income tax and may be subject to state income tax. Build America Bond issuers may elect either (i) to receive payments from the U.S. Treasury equal to a specified percentage of their interest payments (“direct pay”) or (ii) to cause investors in the bonds to receive federal tax credits (“tax credit”). Most issuers of direct pay Build America Bonds currently receive a subsidy from the U.S. Treasury equal to 35% of the interest paid on the bonds, which allows such issuers to issue bonds that pay interest rates that are expected to be competitive with the rates typically paid by private bond issuers in the taxable fixed income market. The bonds in the Fund will not include Build America bonds for which the investors will receive a tax credit. Build America Bonds are currently defined by the Act as restricted from private activity purposes and, for direct pay Build America Bond issuers, the bonds can only be issued to fund capital expenditures. As a result, most Build America Bond issuers have to produce tangible assets that are designed to provide a public benefit. Build America Bonds generally support facilities that meet such essential needs as water, electricity, transportation, and education. Moreover, many Build America Bonds are general obligation bonds, which are backed by the full faith and taxing power of the state and local governments issuing them.Issuance of Build America Bonds ceased on December 31, 2010. The Build America Bonds outstanding at such time continue to be eligible for the federal interest rate subsidy, which continues for the life of the Build America Bonds; however, no bonds issued following expiration of the Build America Bond program are eligible for the federal tax subsidy. The Board of Trustees will continue to evaluate the Fund's investment objective and make appropriate changes, as necessary, that it believes are in the best interests of the Fund and its shareholders, including changing the Fund's investment objective to invest in an index composed of taxable municipal securities.
