This presentation contains forward-looking statements as defined by United States securities laws, including statements about the recently completed acquisition of Investors Financial Services Corp., as well as about our financial goals, the financial outlook and business environment. These statements are not guarantees of future performance, are inherently uncertain, are based on current assumptions that are difficult to predict and involve a number of risks and uncertainties. Therefore, actual outcomes and results may differ materially from what is expressed in those statements, and those statements should not be relied upon as representing State Street’s expectations or beliefs as of any date subsequent to the date of this release. Important factors that may affect future results and outcomes include: State Street’s ability to integrate and convert acquisitions into its business, including the acquisition of Investors Financial Services Corp.; the level and volatility of interest rates, particularly in the U.S. and Europe; the performance and volatility of securities, currency and other markets in the U.S. and internationally; and economic conditions and monetary and other governmental actions designed to address those conditions; the illiquidity of the US and European securities markets, particularly the markets for fixed-income securities, including asset-backed commercial paper, as well as liquidity requirements of State Street’s customers; State Street’s ability to attract non-interest bearing deposits and other low-cost funds; the performance of, and demand for, the investment products State Street offers; the competitive environment in which State Street operates, including its ability to cross-sell services to customers and to maintain service levels, technology, and product offerings that are sufficient to attract new customers and retain current customers, as well as the effects of legal and regulatory proceedings, including litigation; the enactment of legislation, including tax legislation, and changes in regulation and enforcement that impact State Street and its customers; State Street’s ability to continue to grow revenue, control expenses and attract the capital necessary to achieve its business goals and comply with regulatory requirements; State Street’s ability to control systemic and operating risk; trends in the globalization of investment activity and the growth on a worldwide basis in financial assets; trends in governmental and corporate pension plans and savings rates; changes in accounting standards and practices, including changes in the interpretation of existing standards, that impact State Street’s consolidated financial statements; and changes in tax legislation and in the interpretation of existing tax laws by U.S. and non-U.S. tax authorities that impact the amount of taxes due. Other important factors that could cause actual results to differ materially from those indicated by any forward-looking statements are set forth in State Street’s 2006 Annual Report on Form 10-K and its subsequent SEC filings. State Street encourages investors to read these filings, particularly the sections on Risk Factors, for additional information with respect to any forward-looking statements and prior to making any investment decision. The forward-looking statements contained in this presentation speak only as of the date hereof, November 13, 2007, and State Street will not undertake efforts to revise those forward-looking statements to reflect events after this date.
