MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS

State Street Corporation (“State Street” or the “Corporation”) is a financial holding company and reports two lines of business. Investment Servicing provides services for mutual funds and collective funds, corporate and public retirement plans, insurance companies, foundations, endowments, and other investment pools worldwide. Products include custody, product- and participant-level accounting, daily pricing and administration; master trust and master custody; recordkeeping; foreign exchange, brokerage and other trading services; securities lending; deposit and short-term investment facilities; loans and lease financing; investment and hedge fund manager operations outsourcing; and performance, risk and compliance analytics to support institutional investors. Investment Management offers a broad array of services for managing financial assets, including investment management and investment research services, primarily for institutional investors worldwide. These services include passive and active U.S. and non-U.S. equity and fixed income strategies, and other related services, such as securities lending. Financial information about these business lines is provided in this Form 10-Q in the “Line of Business Information” section.

In executing its strategic plan, from time to time State Street may enter into business acquisitions and strategic alliances, and may divest non-strategic operations. State Street continuously reviews and assesses various business opportunities related to this strategy. For information about the Corporation’s current acquisition and divestiture activities, see the “Overview” section of this Management’s Discussion and Analysis of Financial Condition and Results of Operations (“Discussion and Analysis”) and Note 2 to the Consolidated Financial Statements in this Form 10-Q.

This Discussion and Analysis updates State Street’s 2004 Annual Report on Form 10-K and Quarterly Reports on Form 10-Q for the quarters ended March 31 and June 30, 2005, all of which were previously filed with the Securities and Exchange Commission (the “SEC”), and should be read in conjunction with the financial information included in those reports. Certain prior period amounts presented in this discussion have been reclassified to conform to current period classifications. The preparation of financial statements requires management to make estimates and assumptions in the application of certain accounting policies that materially affect the reported amounts of assets, liabilities, revenue and expenses. Actual results could differ from those estimates.

Information related to new accounting developments is included in Notes 1 and 12 to the Consolidated Financial Statements in this Form 10-Q.

OVERVIEW

State Street Corporation recorded net income from continuing operations for the third quarter of 2005 of $250 million, or $.75 per diluted share, compared to $177 million, or $.52 per diluted share, for the third quarter of 2004. Revenue of $1.39 billion in the third quarter of 2005 increased 18%, or $214 million, compared to $1.17 billion in the third quarter of 2004. Total operating expenses for the third quarter of 2005 of $1.01 billion increased 11%, or $ 102 million, compared to $906 million in 2004. For the third quarter of 2005, return on shareholders’ equity from continuing operations was 15.9%, compared to 11.7% in the third quarter of 2004.

For the nine months ended September 30, 2005, net income from continuing operations was $696 million, or $2.08 per diluted share, compared to $614 million, or $1.80 per share for the comparable period in 2004. Revenue of $4.06 billion in 2005 increased 10%, or $377 million, compared to $3.68 billion in 2004. Total operating expenses for year-to-date 2005 of $3.00 billion increased 8%, or $235 million, compared to $2.77 billion in 2004. For the nine months ended September 30, 2005, return on shareholders’ equity from continuing operations was 15.1%, compared to 13.8% in 2004.

Results for the third quarter and first nine months of 2005 compared to the 2004 periods reflected higher servicing, management, securities lending and trading services fee revenue, partially offset by slightly higher operating expenses. The growth rate of revenue exceeded the growth rate of expenses for both 2005 periods.

Overall results for third quarter and year-to-date 2005 included a net loss from discontinued operations of $107 million (charge of $165 million reduced by related tax benefit of $58 million), or $.32 per share. During the third quarter of 2005, State Street committed to a plan to divest its ownership interest in Bel Air Investment Advisors LLC (“Bel Air”). State Street’s decision to divest will allow the Corporation to further sharpen its strategic focus on accommodating the needs of global institutional investors. Given the above, the Corporation realigned its business line organizational and reporting structure for Bel Air. The above-mentioned charge consisted primarily of the write-off of goodwill associated with the original investment and write-downs of tangible assets to fair value less costs to sell. Results of operations for Bel Air for current and prior periods have not been reclassified to discontinued operations because these results are not material to those of the consolidated Corporation. Additional information concerning the Bel Air divestiture is included in Note 2 to the Consolidated Financial Statements in this Form 10-Q.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS (Continued)

Including the loss from discontinued operations, net income for the three and nine months ended September 30, 2005, was $143 million and $589 million, respectively, or $.43 per share and $1.76 per share, respectively. Results for both periods included a gain of $16 million, or $.03 per share, from the final settlement of the 2003 sale of the Private Asset Management (“PAM”) business. Results for the nine months ended September 30, 2005, also included a pre-tax charge of $26 million, or $.05 per share, related to a sub-lease agreement with an unrelated third party.

Results for the third quarter of 2004 included $16 million of merger and integration costs, or $.03 per share, associated with the acquisition of a substantial portion of the Global Securities Services (“GSS”) business of Deutsche Bank AG (“Deutsche Bank”). For the first nine months of 2004, these merger and integration costs were $50 million, or $.10 per share.

RESULTS OF OPERATIONS

Total Revenue

For the third quarter of 2005, total revenue was $1.39 billion, an increase of $214 million compared to $1.17 billion a year earlier. For the nine months ended September 30, 2005, total revenue was $4.06 billion, an increase of $377 million compared to $3.68 billion a year earlier. Fee revenue growth in 2005 was strong across servicing and management fees in both comparisons, reflecting new business from both existing and new clients and stronger equity markets. Securities lending revenue increased due to higher spreads and a higher volume of securities lent, and trading services revenue reflected higher foreign exchange trading and brokerage revenue. Net interest revenue in 2005 was up $23 million in the third quarter and for the first nine months of 2005 compared with a year earlier, reflecting higher balance sheet volumes.

Fee Revenue

Fee revenue for the third quarter of 2005 was $1.14 billion, an increase of $174 million, or 18%, from $961 million in the third quarter of 2004. Servicing fees were up 9%, management fees were up 21%, securities lending revenue was up 54%, and trading services revenue was up 59% from a year earlier. For the nine months ended September 30, 2005, fee revenue was $3.38 billion, reflecting 9% growth in servicing fees, 18% growth in management fees, 28% growth in securities lending revenue and 18% growth in trading services revenue.

Total fee revenue	$	1,135	$	961		$174				18		$	3,375	$	3,019		$	356			12

Servicing fees are derived from custody, product- and participant-level accounting, daily pricing and administration; recordkeeping; investment and hedge fund manager operations outsourcing; master trust and master custody; and performance, risk and compliance analytics. Servicing fees for the third quarter of 2005 were $620 million, up 9% from $568 million in the third quarter of 2004, and for the nine months ended September 30, 2005, were $1.84 billion, up from $1.69 billion a year earlier. The increases in 2005

4

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS (Continued)

were attributable to new business from both existing and new clients, and higher average equity market valuations.

Total assets under custody were $9.80 trillion at September 30, 2005, up 3% from $9.50 trillion at December 31, 2004, and up 9% compared with $9.00 trillion at September 30, 2004. Compared with the prior year periods, daily average values for the S&P 500 Index were up 11% and 7% for the three- and nine-month periods ended September 30, 2005, respectively; daily average values for the MSCI® EAFE Index were up 19% and 15% for the three- and nine-month periods ended September 30, 2005, respectively. The value of assets under custody is a broad measure of the relative size of various markets served. Changes in the value of assets under custody do not result in proportional changes in revenue. Many services are priced on factors other than asset values, including the mix of assets under custody, securities positions held, portfolio transactions, and types of products and services. State Street uses relationship pricing for clients who take advantage of multiple services.

Investment management fees, generated by State Street Global Advisors, were $188 million for the third quarter of 2005, up 21% from $156 million a year earlier, and for the nine months ended September 30, 2005, grew 18% to $538 million. These increases reflected continued new business and an increase in average month-end equity valuations from a year earlier. Total assets under management were $1.41 trillion at September 30, 2005, up from $1.24 trillion a year earlier, reflecting new business and higher equity market valuations. The following table presents a summary of activity in assets under management for the twelve months ended September 30, 2005.

Assets Under Management
(Dollars in billions)
September 30, 2004	$	1,236
Net new business	41
Market appreciation	77
December 31, 2004	1,354
Net new business	27
Market appreciation	29
September 30, 2005	$	1,410

Securities lending revenue for the third quarter of 2005 was $74 million, up 54% compared to $48 million in the third quarter of 2004, driven by higher spreads and an 11% increase in the average volume of securities lent. For the nine months ended September 30, 2005, securities lending revenue was $257 million, up $56 million, or 28%, from a year earlier, due to higher spreads and an approximate 8% increase in the average volume of securities lent. Although securities lending revenue is affected each year by seasonality relative to the historically strong second quarter, third quarter securities lending revenue in 2005 was stronger than that of the prior year third quarter.

Trading services revenue, which includes foreign exchange trading and brokerage revenue and certain other trading fees, was $176 million for the third quarter of 2005, up 59% compared to $111 million from the same period in 2004. Foreign exchange trading revenue increased $46 million, reflecting a 36% increase in volume and an 8% increase in customer-weighted currency volatilities. Brokerage and other trading fees increased $19 million from a year earlier, primarily due to increases in the transition management business.

5

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS (Continued)

Trading services revenue was $512 million for the first nine months of 2005, up from $434 million a year earlier. Foreign exchange trading revenue was up $39 million to $348 million, reflecting a 34% increase in volumes, somewhat offset by lower currency volatilities in the first six months of 2005. Brokerage and other fees increased $39 million, to $164 million from $125 million a year earlier, primarily due to increases in the transition management business.

Processing fees and other revenue was $77 million in the third quarter of 2005 compared to $78 million a year earlier. For the nine months ended September 30, 2005, processing fees and other revenue was $231 million, compared to $235 million for the same period a year earlier. Higher fees from increased activity in structured products offset the lower fees from Deutsche Bank, as deposits of GSS clients were converted to State Street’s systems.

(1)Taxable-equivalent basis includes the tax savings generated by tax-exempt investments as additional net interest revenue. Tax savings were computed using a federal income tax rate of 35%, adjusted for applicable state income taxes, net of the related federal tax benefit.

Net interest revenue for the third quarter of 2005 was $236 million, up $23 million, or 11%, from the third quarter of 2004. For the nine months ended September 30, 2005, net interest revenue was up $23 million at $665 million compared to the 2004 period, which included the first-quarter impact of a $19 million reduction in interest revenue due to a change in the applicable state tax rate for leveraged lease transactions. Excluding this reduction from 2004 amounts, net interest revenue would have increased by $4 million during the first nine months of 2005. These increases were achieved despite a challenging interest-rate environment driven by eight federal funds rate increases over the preceding twelve months.

6

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS (Continued)

Higher revenue was principally due to increases in the size of the Corporation’s balance sheet, including the conversion of GSS deposits to State Street’s balance sheet, and the impact of repositioning and increasing the size of the Corporation’s investment securities portfolio. At September 30, 2005, State Street’s investment securities portfolio included a higher percentage of collateralized mortgage obligations and floating rate, asset-backed securities when compared to a year earlier, and a lower percentage of U.S. Treasuries and direct obligations of federal agencies. The shift in the portfolio was designed to better position the Corporation in a rising short-term interest-rate environment, without significantly increasing overall risk by continuing to invest conservatively in AA and AAA rated securities. AA and AAA rated securities comprised approximately 96% of the investment securities portfolio, with approximately 91% AAA rated, at September 30, 2005.

Gain on Sales of Available-for-Sale Securities

State Street realized a net gain of $1 million on sales of available-for-sale securities in the third quarter of 2005, compared with no net gain in the prior year. A net gain of $1 million was recorded for the nine months ended September 30, 2005, down from a net gain of $19 million for the same period a year earlier.

Gain on Sale of Private Asset Management Business

In October 2003, State Street completed the sale of its PAM business, with approximately five percent of the transaction price of $365 million subject to successful transition of the business. During the third quarter of 2005, State Street recorded an additional gain of $16 million from final settlement of the sale. Additional information concerning the gain is included in Note 2 to the Consolidated Financial Statements in this Form 10-Q.

Operating Expenses

Total operating expenses increased from $906 million in the third quarter of 2004 to $1.01 billion in 2005, up $102 million, or 11%. For the first nine months of 2005, total operating expenses of $3.00 billion were up $235 million, or 8%, from $2.77 billion a year earlier. The nine-month comparison reflected a pre-tax charge of $26 million related to a long-term sub-lease of a portion of the Corporation’s headquarters recorded in the second quarter of 2005. Operating expenses for the third quarter and first nine months of 2004 included $16 million and $50 million, respectively, of merger and integration costs related to the acquisition of the GSS business of Deutsche Bank. Increases in salaries and employee benefits, transaction

processing, occupancy and other expenses in both comparisons were somewhat offset by declines in merger and integration costs and information systems and communications expense.

Salaries and employee benefits expense was up 19% to $566 million for the third quarter of 2005 compared to the same period in 2004, and increased 14%, to $1.64 billion, for the nine months ended September 30, 2005, compared with the same period a year earlier. These increases primarily resulted from additions to staff to service investment manager outsourcing operations after adding three large outsourcing clients in 2004, and the impact of higher incentive compensation accruals based on improvements in business line earnings. Other contributing factors were higher benefit costs and the impact of merit adjustments.

Information systems and communications expense for the third quarter of 2005 declined $10 million, or 8%, to $117 million from the third quarter of 2004, and declined $32 million, or 8%, for the first nine months of 2005 compared to a year earlier, due to cost reductions related to the integration of the GSS business to State Street systems, partially offset by increases related to the new data center coming fully on line in the fourth quarter of 2004.

Transaction processing expense increased $16 million, or 17%, to $111 million for the third quarter of 2005 compared to a year earlier, and increased $37 million for the first nine months of 2005 compared to a year earlier, due to higher volumes in the brokerage business.

For the third quarter of 2005, occupancy expense increased $8 million to $96 million from a year earlier, reflecting the cost of additional space to accommodate new business outside the United States and increased operating costs. Occupancy expense increased $40 million for the first nine months of 2005 compared to a year earlier. Year-to-date results for 2005 reflect a pre-tax charge of $26 million in the second quarter of 2005 related to a long-term sub-lease agreement with an unrelated third party for approximately 150,000 square feet in the headquarters building. State Street expects that this transaction will reduce average annual occupancy costs for this property going forward by $7 million to $8 million beginning in 2006. As the Corporation completes the realignment of its real estate portfolio, additional sub-leasing agreements may be entered into to eliminate excess space.

Other expenses for the third quarter of 2005 rose 11%, or $12 million, to $118 million, and were up $44 million, or 14% for the year-to-date period, primarily due to increased costs for compliance, regulatory initiatives and other professional services.

Income Taxes

State Street recorded income tax expense from continuing operations of $130 million for the third quarter of 2005, up from $91 million in the third quarter of 2004, and recorded income tax expense from continuing operations of $359 million for the first nine months of 2005, compared to $299 million in 2004, both increases primarily the result of increased pre-tax earnings. Tax expense for the first nine months of 2004 included a cumulative tax benefit of $18 million resulting from a change in the effective state tax rate applied to leveraged leasing transactions.

The effective tax rate for continuing operations for both the third quarter and first nine months of 2005 was 34.0%, compared to 34.0% and 32.8% for the three and nine months ended September 30, 2004, respectively. The expected tax rate for full-year 2005 on a continuing operations basis is 34.0%, compared with 33.1% for full-year 2004. Both the nine-month and full-year 2004 effective rates reflected the previously disclosed $18 million cumulative tax benefit from leveraged leases. Excluding the tax benefit, the effective rate for full-year 2004 would have been 34.0%.

During the third quarter of 2005, the Financial Accounting Standards Board (“FASB”) issued a proposed FASB Staff Position (“FSP”) for comment addressing accounting for changes in the expected timing of tax-related cash flows of leveraged leases. The proposed FSP would require companies to record any charge resulting from the adoption of the FSP as a cumulative effect of a change in accounting principle. Depending on the ultimate requirements of the final FSP and the timing of its issuance and effective date, the guidance may require a material cumulative charge to State Street’s income in the fourth quarter of 2005. However, future income would be expected to increase over the remaining terms of the leases by an amount approximately equal to the charge, exclusive of any tax-related interest and penalties that may be included in the charge. For additional information about this matter and other proposed new accounting guidance, refer to Note 12 to the Consolidated Financial Statements in this Form 10-Q.

Line of Business Information

State Street reports two lines of business: Investment Servicing and Investment Management. Given State Street’s services and management organization, the results of operations for these lines of business are not necessarily comparable with those of other companies, including companies in the financial services industry. Additional information about State Street’s lines of business is included in Note 13 to the Consolidated Financial Statements in the Corporation’s 2004 Annual Report on Form 10-K.

Investment Servicing

Total revenue for the three and nine months ended September 30, 2005 was $1.13 billion and $3.33 billion, respectively, an increase of 15% for the third quarter and a 7% increase for the nine months compared to the 2004 periods. Both increases were driven by growth in fee revenue, as net interest revenue for the third quarter was up 7%, but was relatively flat for the first nine months, compared to 2004.

Fee revenue for the three and nine months ended September 30, 2005 increased $128 million and $240 million, respectively, compared to the 2004 periods, with the increases attributable to growth in servicing, securities lending and trading services fees, partly offset by declines in processing fees and other. Servicing fees, securities lending, and trading services revenue for Investment Servicing comprise most of these types of revenues reflected in the consolidated results of the Corporation. Refer to the “Results of Operations—Fee Revenue” section of this Discussion and Analysis for additional information.

Net interest revenue after provision for loan losses for the three and nine months ended September 30, 2005 was $216 million and $609 million, respectively, up for the third quarter but relatively flat for the first nine months when compared to 2004. Shifts in the mix of investments and higher average balance sheet volumes offset a flatter yield curve during the third quarter of 2005. The third-quarter increase offset most of the decline in net interest revenue during the first six months of the year.

Operating expenses for the third quarter of 2005 were $834 million, and were $2.51 billion for the nine months ended September 30, 2005, increases of 11% and 10%, respectively, compared to 2004. The increases were attributable to higher salaries, reflecting the higher costs of benefits and merit increases, growth in transaction processing costs reflecting higher volumes for this line of business and higher

11

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS (Continued)

professional services costs related to compliance and growth initiatives, partly offset by lower information systems and communications costs due to the integration of the GSS business to State Street’s systems.

Investment Management

Total revenue for the three and nine months ended September 30, 2005 increased 29% and 25%, respectively, from the comparable periods in 2004, with the increases driven by growth across all lines of revenue.

Management fees from investment management services, delivered through State Street Global Advisors, were $188 million for the third quarter of 2005 and $538 million for the year-to-date period, and comprise all of the management fees reflected in the consolidated results of the Corporation. Refer to the “Results of Operations—Fee Revenue” section of this Discussion and Analysis for additional information. Improvement in securities lending revenue reflected higher spreads and an increase in the volume of securities lent.

Operating expenses for the three and nine months ended September 30, 2005, were $174 million and $492 million, respectively, up 27% and 15% from the comparable periods in 2004, primarily attributable to higher salaries and employee benefits.

Financial Goals and the Risk Factors That May Affect Them

State Street has announced financial goals for the Corporation for 2005 and beyond. The goals are (1) annual growth in operating earnings per share from continuing operations of 10% to 15%, (2) annual operating revenue growth of 8% to 12%, and (3) annual operating return on shareholders’ equity from continuing operations of 14% to 17%. State Street expects to be at the lower end of the range for revenue, and approximately in the middle of the ranges for growth in operating earnings per share and return on equity, both from continuing operations, for the year ending December 31, 2005.

The Corporation prepares its consolidated statement of income in accordance with accounting principles generally accepted in the United States (“GAAP”); however, it measures the achievement of its financial goals on an operating basis. Operating basis results are based on GAAP results, excluding the impact of significant, non-recurring transactions and activities, presented on a fully taxable-equivalent basis. Operating basis results for full-year 2005 exclude the loss from discontinued operations related to Bel Air, and any charges that could result from the application of proposed new accounting guidance related to leveraged leases and tax contingencies. More information about these matters is included in Notes 2 and 12 to the Consolidated Financial Statements in this Form 10-Q.

State Street considers these to be financial goals, not projections or forward-looking statements. However, this Discussion and Analysis and other portions of this Form 10-Q may contain statements that are considered “forward-looking statements” within the meaning of federal securities laws. These statements may be identified by such forward-looking terminology as “expect,” “look,” “believe,” “anticipate,” “may,” “will,” or similar statements or variations of such terms. The Corporation’s financial goals and such forward-looking statements involve certain risks and uncertainties, including the issues and risk factors listed below and factors further described in conjunction with the forward-looking information, which could cause actual results to differ materially. The following issues and risk factors should be carefully considered. The forward-looking statements contained in this Form 10-Q speak only as of the time the statements were given. The Corporation does not undertake to revise those forward-looking statements to reflect events after the date of this report.

12

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS (Continued)

Cross-border Investing.Increased cross-border investing by clients worldwide benefits State Street’s revenue. Future revenue may increase or decrease depending upon the extent of increases or decreases in cross-border investments made by clients. Economic and political uncertainties resulting from terrorist attacks, subsequent military actions or other events could result in decreased cross-border investment activities.

Savings Rates of Individuals.   State Street generally benefits when individuals invest their savings in mutual funds and other collective funds or in defined contribution plans. Changes in savings rates or investment styles may affect revenue. If there is a decline in the savings rates of individuals, or if there is a change in investment preferences that leads to fewer investments in mutual funds, other collective funds, and defined contribution plans, State Street’s revenue may be adversely affected.

Asset Values in Worldwide Financial Markets.   As asset values in worldwide financial markets increase or decrease, State Street’s opportunities to invest and service financial assets may change. Since a portion of State Street’s fees is based on the value of assets under custody and management, fluctuations in the valuation of worldwide securities markets will affect revenue.

As asset values increase or decrease due to external credit factors, State Street has exposure related to its own investing activities. The impact of such exposure would be reflected in State Street’s consolidated statements of income, condition and changes in shareholders’ equity.

Dynamics of Markets Served.   Changes in markets served, including the growth rate of collective funds worldwide, outsourcing decisions, mergers, acquisitions and consolidations among clients and competitors and the pace of debt and equity issuance, can affect Sate Street’s revenue. In general, the Corporation benefits from increases in the volume of financial market transactions serviced.

State Street provides services worldwide. Global and regional economic factors and changes or potential changes in laws and regulations affecting State Street’s business—including volatile currencies, the pace of inflation, changes in monetary policy, changes in domestic and international banking supervisory regulations including capital requirements, and social and political instability—could affect its results of operations. Terrorist activities and related military actions have caused economic and political uncertainties, have affected and may further adversely affect economic growth, and may have other adverse effects on many companies, including State Street, in ways that are not predictable.

Financial reporting irregularities involving large and well-known companies and governmental and regulatory investigations of securities and mutual fund industry practices and behavior may have adverse effects on State Street in ways that are not predictable. State Street is broadly involved with the securities industry including, in particular, the mutual fund industry, and governmental and regulatory agencies have sought information from the Corporation in connection with investigations relating to that industry.

Legislation may cause changes in the competitive environment in which State Street operates, which could include, among other things, broadening the scope of activities of significant competitors, or facilitating consolidation of competitors into stronger entities, or attracting new large and well-capitalized competitors into State Street’s traditional businesses. Such factors and changes, and the Corporation’s ability to address and adapt to the competitive challenges, may affect its future results of operations.

Regulation and Supervision.   State Street’s businesses are subject to stringent regulation and examination by governmental and regulatory agencies and self-regulatory organizations (including securities exchanges) both inside and outside the U.S. The Corporation has established policies,

13

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS (Continued)

procedures, and systems designed to comply with these regulatory requirements. However, as a global financial services institution, State Street faces complexity and costs in its worldwide compliance efforts, and faces the potential for loss resulting from failure to comply with these requirements, which could have a material impact on its future results of operations. Also, adverse publicity and damage to State Street’s reputation arising from the failure or perceived failure to comply with legal or regulatory requirements could affect the Corporation’s ability to attract and retain customers or maintain access to capital markets, or could result in enforcement actions, fines, penalties, and lawsuits.

Operational Risk.   State Street has the potential to incur losses resulting from inadequate or failed internal processes, people and systems. In addition, external events, including terrorist or military actions and resulting political and social turmoil, could arise that would cause unforeseen damage to the Corporation’s physical facilities or could cause delays or disruptions to its operational functions, including information processing and financial market settlement functions. Additionally, State Street’s clients, vendors and counterparties could suffer from such events, which may impact the Corporation. State Street has well-established policies, procedures, systems, and business continuity and disaster recovery plans in place that are designed to address these operational risks. However, an adverse effect on the Corporation’s results of operations could occur.

GAAP.   Changes in GAAP applicable to State Street could have a material impact on its consolidated results of operations. While such changes may not have an economic impact on the Corporation’s business, these changes could affect the attainment of the current measures of its financial goals.

Tax Legislation.   Changes in tax legislation or the interpretation of existing tax laws worldwide could have a material impact on State Street’s results of operations.

Interest Rates.   Levels of market interest rates, the shape of the yield curve, and the direction and speed of interest rate changes relative to the geographic mix of interest-bearing assets and liabilities affect State Street’s net interest revenue and securities lending revenue. In the short term, the Corporation’s net interest revenue and securities lending revenue benefit from falling interest rates and are negatively affected by rising interest rates because interest-bearing liabilities reprice sooner than interest-earning assets. The rate of adjustment to higher or lower rates will depend on the relative duration of assets and liabilities. In general, sustained lower interest rates and a flat yield curve have a constraining effect on net interest revenue and securities lending revenue growth. Market interest rates also impact the value of certain derivative products whose change in value is reflected in processing fees and other in State Street’s consolidated statement of income.

Liquidity.   State Street’s ability to maintain consistent access to liquidity is fostered by strong credit ratings from the major independent credit rating agencies. Factors considered by the rating agencies in assigning high credit ratings include diverse and stable core earnings; strong risk management; strong capital ratios; diverse liquidity sources, including the global funds markets and client deposits; and strong liquidity monitoring procedures. Any occurrence that may limit access to liquidity, such as a decline in the confidence of debt purchasers, depositors or counterparties participating in the funds markets in general or with State Street in particular, or a downgrade of State Street’s credit ratings, could affect the Corporation’s capital costs and its ability to raise capital and, in turn, its liquidity.

Capital.   Under regulatory capital adequacy guidelines, the Corporation and its subsidiary, State Street Bank and Trust Company (“State Street Bank”), must meet guidelines that involve quantitative measures of assets, liabilities, and certain off-balance sheet items. Failure to meet minimum capital

14

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS (Continued)

requirements could have a direct material effect on the Corporation’s financial condition; and failure to maintain the status of “well capitalized” under the regulatory framework could affect the Corporation’s status as a financial holding company and eligibility for a streamlined review process for acquisition proposals.

In addition, failure to maintain the status of “well capitalized” could affect the confidence of the Corporation’s clients in State Street and could adversely affect its business. In addition to being well-capitalized, the Corporation and State Street Bank are subject to guidelines that involve qualitative judgments by regulators about the entities’ status as well-managed and the entities’ compliance with Community Reinvestment Act obligations.

Federal laws and related regulations limit the amount that banks, including State Street Bank, may invest in international subsidiaries. This limitation may affect the pace of future international expansion by State Street Bank through this type of subsidiary.

Volatility of Currency Markets.   The degree of volatility in foreign exchange rates can affect foreign exchange trading revenue. In general, State Street benefits from currency volatility. Accordingly, foreign exchange revenue is likely to decrease during times of decreased currency volatility. In addition, as the Corporation’s business grows globally, its exposure to changes in foreign currency exchange rates could impact the level of revenue and expense and net income and the value of State Street’s investments in its non-U.S. operations.

Pace of Pension Reform.   The Corporation expects its business to benefit from worldwide pension reform that creates additional pools of assets that use custody and related services, and investment management services. The pace of pension reform and resulting programs, including public and private pension schemes, may affect the pace of State Street’s revenue growth. If the pace of pension reform and resulting programs, including public and private pension schemes, slows down or if pension reform does not occur, State Street’s revenue growth may be adversely affected.

Pricing and Competition.   Future prices State Street is able to obtain for its products may increase or decrease from current levels depending upon demand for the Corporation’s products, its competitors’ activities, customer pricing reviews, and the introduction of new products into the marketplace.

Pace of New Business; Business Mix.   A decline in the pace at which State Street attracts new clients, and the pace at which the Corporation’s existing and new clients use additional services and assign additional assets to State Street for management or custody, may adversely affect the Corporation’s future revenue and earnings growth. A decline in the rate at which State Street’s clients outsource functions, such as their internal accounting activities, could also adversely affect revenue and earnings growth. In addition, changes in business mix and in the source of State Street’s revenue, including the mix of U.S. and non-U.S. business, may affect its future results of operations, depending on the economic and competitive conditions of those geographic areas at the time.

Investment and Hedge Fund Manager Operations Outsourcing.   State Street enters into long-term contracts to provide middle office or investment management operations outsourcing services to its clients. Services include trade order management, trade support and fail management, reconciliations, cash reporting and management, custodian communications for settlements, accounting systems, collateral management, and information technology development. These contracts often extend for eight to ten years and require considerable up-front investments by the Corporation, including technology and conversion

15

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS (Continued)

costs. Performance risk exists in each contract as these contracts are dependent upon the successful conversion and implementation of the activities onto State Street’s own operating platforms.

Rate of Technological Change.   Technological change often creates opportunities for product differentiation and reduced costs, as well as the possibility of increased expenses. Developments in the securities processing industry, including shortened settlement cycles and straight-through-processing, will result in changes to existing procedures. Alternative delivery systems have emerged, including the widespread use of the Internet. State Street’s financial performance depends in part on its ability to develop and market new and innovative services, and to adopt or develop new technologies that differentiate its products or provide cost efficiencies.

The risks inherent in this process include rapid technological change in the industry, State Street’s ability to access technical and other information from its clients, and the significant and ongoing investments required by State Street to bring new services to market in a timely fashion at competitive prices. A further risk is the introduction by the Corporation’s competitors of services that could replace or provide lower-cost alternatives to its services.

State Street uses trademark, trade secret, copyright and other proprietary rights procedures to protect its technology, and has applied for a limited number of patents in connection with certain software programs. Despite these efforts, the Corporation cannot be certain that its steps taken to prevent unauthorized use of its our proprietary rights are sufficient to prevent misappropriation of its technology, particularly outside the United States where laws or law enforcement practices may not protect proprietary rights as fully as in the United States. In addition, no assurance can be given that the courts will adequately enforce contractual agreements that State Street has entered into to protect its proprietary technology. If any of the Corporation’s proprietary information were misappropriated by or otherwise disclosed to its competitors, State Street’s competitive position could be adversely affected. In the event a third party asserts a claim of infringement of its proprietary rights, obtained through patents or otherwise, against the Corporation, State Street may be required to spend significant resources to defend against such claims, develop a non-infringing program or process, or obtain a license to the infringed process.

Acquisitions, Alliances, Outsourcing Agreements and Divestitures.Acquisitions of complementary businesses and technologies, development of strategic alliances, execution of outsourcing agreements, and divestitures of portions of the Corporation’s business are an active part of State Street’s overall business strategy. The Corporation has completed several acquisitions, alliances, outsourcing agreements, and divestitures in recent years. However, there can be no assurance that services, technologies, key personnel, or businesses of acquired companies or from outsourcing agreements will be effectively assimilated into State Street’s business or service offerings, that alliances will be successful, or that future revenue growth or expense savings will be achieved in outsourcing agreements. In addition, State Street may not be able to successfully complete any divestiture on satisfactory terms, if at all, and divestitures may result in a reduction of the Corporation’s total revenue and net income.

Capital

At September 30, 2005, State Street and State Street Bank met all capital adequacy requirements to which they were subject. The regulatory capital amounts and ratios were as follows at September 30, 2005 and December 31, 2004:

	Regulatory Guidelines(1)
				Well			State Street						State Street Bank
(Dollars in millions)	Minimum			Capitalized			2005			2004			2005			2004
Tier 1 risk-based capital ratio		4	%		6	%	11.5		%	13.3		%	9.9		%	11.6		%

Adjusted risk-weighted assets and market-risk equivalents:
Balance sheet risk-weighted assets							$28,252			$	22,741		$	26,673		$	21,587
Off-balance sheet equivalent risk-weighted assets							19,464			16,398			19,468			16,403
Market-risk equivalents							258			261			247			226
Total							$47,974			$	39,400		$	46,388		$	38,216
Quarterly average adjusted assets							$	99,413		$	94,834		$	86,190		$	83,843

⁽¹⁾      State Street Bank must meet the regulatory designation of “well capitalized” in order to maintain State Street’s status as a financial holding company, including maintaining a minimum Tier 1 risk-based capital ratio (Tier 1 capital divided by adjusted risk-weighted assets and market-risk equivalents) of 6%, a minimum total risk-based capital ratio (total capital divided by adjusted risk-weighted assets and market-risk equivalents) of 10%, and a Tier 1 leverage ratio (Tier 1 capital divided by quarterly average adjusted assets) of 5%. In addition, Federal Reserve Regulation Y defines “well capitalized” for a bank holding company such as State Street for the purpose of determining eligibility for a streamlined review process for acquisition proposals. For such Regulation Y purposes, “well capitalized” requires State Street to maintain a minimum Tier 1 risk-based capital ratio of 6% and a minimum total risk-based capital ratio of 10%.

At September 30, 2005, the Corporation’s and State Street Bank’s Tier 1 and total risk-based capital ratios were down from year-end 2004. Growth in capital was outpaced by growth in total risk-weighted assets, primarily the result of repositioning and increasing the size of the investment securities portfolio; an increase in loans; and the impact of new banking regulatory guidance related to the risk-weighting of liquidity facilities with certain special purpose entities, partly offset by lower interest-bearing deposits with banks. Both ratios for State Street and State Street Bank exceeded the regulatory minimum and well-capitalized thresholds.

In June 2004, the Basel Committee on Banking Supervision released the final version of its capital adequacy framework (“Basel II”). U.S. banking regulatory agencies must now apply international risk-based capital guidance to rules to be implemented in the U.S. In September 2005, the U.S. regulators

17

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS (Continued)

announced a delay in the issuance of proposed rules and a revised implementation schedule. The U.S. regulatory agencies are expected to release proposed new rules for comment in the first quarter of 2006. The new rules as applied in the U.S. are now expected to become effective on January 1, 2008, subject to transitional implementation arrangements, and will become fully operational on January 1, 2009, one year later than originally planned. In addition to changes in the implementation schedule, the U.S. regulators intend to introduce additional prudential safeguards to address concerns identified in a recent analysis of an impact study conducted with the U.S. banking industry. Mandatory compliance will be required for large, internationally-active U.S. institutions, such as State Street. State Street has established a comprehensive implementation program to achieve Basel II compliance. At this time, State Street cannot predict the final form of the rules in the U.S., nor their impact on the Corporation’s risk-based capital.

State Street’s Board of Directors (the “Board”) has authorized the purchase of State Street common stock for use in employee benefit programs and for general corporate purposes. During the first quarter of 2005, 2.9 million shares were purchased under the 1995 stock purchase program. In February 2005, the 1995 stock purchase program was terminated, and in its place, the Board authorized the purchase of 15 million shares under the 2005 stock purchase program. During the second and third quarters of 2005, 2.2 million shares and 3.1 million shares, respectively, were purchased under the 2005 stock purchase program, and at September 30, 2005, 9.7 million shares remained available for future purchases. See Note 6 to the Consolidated Financial Statements in this Form 10-Q for additional information.

In connection with the acquisition of the GSS business of Deutsche Bank in January 2003, State Street issued $345 million, or 1,725,000 units, of “SPACES.” For a description of the SPACES contracts, refer to Note 10 to the Consolidated Financial Statements in State Street’s 2004 Annual Report on Form 10-K. On November 15, 2005, State Street will receive proceeds of $345 million and issue approximately 8.7 million shares of its common stock upon settlement of the fixed-share purchase contracts underlying the SPACES units. State Street will receive approximately 1.2 million shares under the variable-share repurchase contracts on February 15, 2006. On December 15, 2005, State Street will be required to redeem $345 million of trust preferred securities which are included in long-term debt in its consolidated statement of condition, provided that the Corporation is well-capitalized. Consent to redeem the trust preferred securities was received from the Federal Reserve in October 2005.

Liquidity

The primary objective of State Street’s liquidity management is to ensure that the Corporation has sufficient funds to meet its commitments and business needs, including accommodating the transaction and cash management requirements of its clients. Liquidity is provided by State Street’s access to global debt markets, its ability to gather additional deposits from its clients, maturing short-term assets, sales of securities, and repayment of clients’ loans. Client deposits and other funds provide multi-currency, geographically diverse sources of liquidity.

State Street maintains a large portfolio of liquid assets, defined as cash and due from banks, interest-bearing deposits with banks, securities purchased under resale agreements, federal funds sold, trading account assets and investment securities. At September 30, 2005, the Corporation’s liquid assets were $87.28 billion, or 84% of total consolidated assets, a significant portion of which can be sold in the open market to meet liquidity needs. At December 31, 2004, liquid assets were $79.31 billion, or 84% of total consolidated assets. Securities with a carrying value of $17.24 billion at September 30, 2005, and $24.77 billion at December 31, 2004, were pledged, primarily for public and trust deposits, certain short-term liabilities and for other purposes as provided by law. At September 30, 2005, State Street’s

AND RESULTS OF OPERATIONS (Continued)

short-term liabilities, defined as deposits, securities sold under repurchase agreements, federal funds purchased and other short-term borrowings, were $88.59 billion, compared to $78.79 billion at December 31, 2004. State Street had $356 million in pre-tax net unrealized losses on available-for-sale investment securities at September 30, 2005, due primarily to the impact of rising short-term interest rates. Net unrealized losses on available-for-sale securities at June 30, 2005 were $165 million, and at December 31, 2004 were $96 million. The Corporation considers the aggregate decline in fair value at September 30, 2005 to be temporary.

State Street maintains a universal shelf registration that allows for the offering and sale of unsecured debt securities, capital securities, common stock, depositary shares and preferred stock, and warrants to purchase such securities, including any shares into which the preferred stock and depositary shares may be convertible, or any combination thereof. At September 30, 2005, $469 million of State Street’s shelf registration was available for issuance.

State Street can issue commercial paper with an aggregate limit of $3.00 billion and with original maturities of up to 270 days from the date of issue. At September 30, 2005, State Street had $1.26 billion of commercial paper outstanding, compared to $966 million at December 31, 2004.

State Street Bank has authority to issue bank notes with an aggregate limit of $750 million and with original maturities ranging from 14 days to five years. At September 30, 2005, no notes payable were outstanding and all $750 million was available for issuance. In 2003, State Street Bank was authorized to issue up to $1 billion of subordinated bank notes. At September 30, 2005, $400 million was outstanding and $600 million remained available for issuance.

State Street Bank currently maintains a line of credit with a financial institution of CAD $800 million to support its Canadian securities processing operations. The line of credit has no stated termination date and is cancelable by either party with prior notice. At the close of business on September 30, 2005, State Street Bank did not have any balance due on the line of credit.

State Street endeavors to maintain high investment-grade ratings on its debt, as measured by the major independent credit rating agencies. High ratings on debt minimize borrowing costs and enhance State Street’s liquidity by ensuring the largest possible market for the Corporation’s debt.

Based upon the Corporation’s level of liquid assets and its ability to access the capital markets for additional funding when necessary, including its ability to issue debt and equity securities under its current shelf registration, management considers overall liquidity at September 30, 2005 more than sufficient to meet its current commitments and business needs, including accommodating the transaction and cash management needs of its clients.

Risk Management

Economic Capital

During 2004, State Street implemented a methodology to quantify its economic capital needs. The Corporation defines economic capital as the common equity required to protect debt holders against unexpected economic losses over a one-year period at a level consistent with the solvency of a firm with State Street’s target debt rating. State Street quantifies capital requirements for the risks inherent in its business activities and groups them into one of the following broadly-defined categories.

·Market risk: the risk of adverse financial impact due to fluctuations in market prices, primarily as they relate to State Street’s trading activities.

·Interest-rate risk: the risk of loss in non-trading, asset-liability management positions, primarily the impact of adverse movements in interest rates on the repricing mismatches that exist between balance sheet assets and liabilities.

·Credit risk: the risk of loss that may result from the default or downgrade of a borrower or counterparty.

·Operational risk: the risk of loss from inadequate or failed internal processes, people, and systems, or from external events, which is consistent with the Basel II definition.

·Business risk: the risk of adverse changes in the Corporation’s earnings from business factors, including changes in the competitive environment, changes in the operational economics of business activities, and the effect of strategic and reputation risks.

Economic capital for each of these five categories is estimated on a stand-alone basis using statistical modeling techniques applied to internally generated and external data. These individual results are then aggregated at the State Street consolidated level. A capital reduction or diversification benefit is then applied to reflect the unlikely event of experiencing an extremely large loss in each risk type at the same time.

Because the amount of economic capital varies directly with the Corporation’s overall level of risk, it has become an integral part of State Street’s internal capital management process. Economic and regulatory capital are key metrics used by management to ensure that State Street’s actual level of capital is commensurate with its risk profile, in compliance with all regulatory requirements, and sufficient to provide the Corporation with the financial flexibility to undertake future strategic business initiatives.

The framework and methodologies used to quantify capital for each of the risk types have been developed by Enterprise Risk Management and Global Treasury and are designed to be generally consistent with the Corporation’s risk management principles. This framework has been approved by senior management and has been reviewed by the Executive Committee of the Board. Due to the evolving nature of quantification techniques, State Street expects to continue refining the methodologies used to estimate its economic capital requirements, which could result in a different amount of capital needed to support its risk profile.

Market Risk

Trading Activities: Foreign Exchange and Interest Rate Sensitivity

As part of its trading activities, the Corporation takes positions in both the foreign exchange and interest rate markets by buying and selling cash instruments and using financial derivatives, including foreign exchange forward contracts, foreign exchange and interest rate options, and interest rate swaps. At September 30, 2005, the notional amount of these derivative instruments was $475.87 billion, of which $456.61 billion were foreign exchange forward contracts. In the aggregate, long and short foreign exchange forward positions are closely matched to minimize currency and interest rate risk. All foreign exchange contracts are valued daily at current market rates.

The following table presents State Street’s market risk for its trading activities, as measured by its value-at-risk methodology for the periods indicated:

(Dollars in millions)	Average			Maximum			Minimum
Nine months ended September 30, 2005:
Foreign exchange products		$	1.4		$	3.3		$	.5
Interest rate products		1.0			3.0			.3
Nine months ended September 30, 2004:
Foreign exchange products		$	1.2		$	3.5		$	.3
Interest rate products		1.7			3.0			1.0

State Street compares daily profits and losses from trading activities to the estimated one-day value at risk. This information is reviewed and used to assure that the value-at-risk model is properly calibrated and that all relevant trading positions are taken into account.

Non-Trading Activities—Interest-Rate Sensitivity

The objective of interest-rate sensitivity management is to provide sustainable net interest revenue under various economic environments and to protect the economic values of assets and liabilities from adverse effects of changes in interest rates. State Street manages the structure of its interest-earning assets and interest-bearing liabilities by adjusting the mix, yields and maturity or repricing characteristics based on market conditions. During 2004, State Street created a centralized, global treasury function to manage State Street’s interest-rate risk. Since interest-bearing sources of funds are predominantly short-term, State Street maintains a relatively short-term structure for its interest-earning assets, including money market assets, investments and loans. Interest-rate swaps are used minimally as a part of overall asset and liability management to augment State Street’s management of its interest-rate exposure.

State Street uses three primary tools for measuring interest-rate risk: simulation, duration and gap analysis models. Key assumptions in the models include the timing of cash flows, maturity and repricing of financial instruments, changes in market conditions, capital planning, and deposit balance volume and rate sensitivities. These assumptions are inherently uncertain and as a result, the models cannot precisely calculate net interest revenue or precisely predict the impact of changes in interest rates on net interest revenue and economic value. Actual results may differ from simulated results due to the timing, magnitude and frequency of interest-rate changes and changes in market conditions and management strategies, among other factors.

21

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS (Continued)

Simulation models facilitate the evaluation of the potential range of net interest revenue under a “most likely” scenario, alternative interest-rate scenarios and rate shock tests. Duration measures the change in the economic value of assets and liabilities for given changes in interest rates. Gap analysis is the difference in asset and liability repricing on a cumulative basis within a specified time period.

If all other variables remained constant, in the short term, falling interest rates would lead to net interest revenue that is higher than it would otherwise have been, and rising rates would lead to lower net interest revenue. Other important determinants of net interest revenue are balance sheet size and mix, interest-rate spreads, and the slope and rate level of U.S. dollar and non-U.S. dollar yield curves. Measures of interest-rate sensitivity are monitored by the respective business units, Treasury and the Investment and Financial Policy Committees.

State Street had $356 million in pre-tax net unrealized losses on its available-for-sale investment securities at September 30, 2005.  Net unrealized losses on available-for-sale securities at June 30, 2005 were $165 million, and at December 31, 2004 were $96 million.  The Corporation considers the aggregate decline in fair value and resulting net unrealized losses on its available-for-sale investment securities at September 30, 2005 to be primarily the result of rising short-term interest rates, and considers the decline to be temporary. Approximately 96% of State Street’s investment securities portfolio was AA and AAA rated, with approximately 91% AAA rated, at September 30, 2005. State Street will continue to manage its investment securities portfolio pursuant to its overall asset-liability management strategy, in consideration of the current rising short-term interest rate environment.

Credit Risk

At September 30, 2005, total gross loans were $8.19 billion compared to $4.63 billion at December 31, 2004, reflecting a large increase in daily overdrafts, which do not represent a significant increase in credit risk due to their short-term nature. The allowance for loan losses was $18 million, unchanged from December 31, 2004, and down from $36 million at September 30, 2004. For the nine months ended September 30, 2005, no provision for loan losses was charged against income, and there were no charge-offs or recoveries.

Non-performing assets at September 30, 2005 were $4 million, consisting of one non-performing investment security, compared to $7 million at December 31, 2004. In addition to credit risk in its investment and loan and lease portfolios, State Street assumes credit and counterparty risk in other on- and off-balance sheet exposures.

Operational Risk

State Street defines operational risk as the potential for losses resulting from inadequate or failed internal processes, people and systems, or from external events. State Street is the world’s leading provider of services to institutional investors, and the Corporation’s clients have a broad array of complex and specialized servicing, confidentiality and fiduciary requirements. Active management of operational risk is an integral component of all aspects of State Street’s business and responsibility for the management of operational risk lies with every individual in the Corporation. State Street’s Operational Risk Policy Statement defines operational risk and details roles and responsibilities for managing operational risk. It provides a mandate within which sound practices, including programs, processes, and those elements required by regulation, are implemented to ensure that operational risk is identified, measured, managed and controlled in an effective and consistent manner across the Corporation.

22

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS (Continued)

State Street maintains an operational risk governance structure to ensure responsibilities are clearly defined and to provide independent oversight of operational risk management. Enterprise Risk Management oversees the Corporation’s enterprise-wide operational risk management program. The Major Risk and Operational Risk Committees review key metrics and policies related to operational risk, provide oversight functions to ensure compliance with the operational risk program, and escalate operational risk issues of note to the Executive Committee of the Board. Corporate Audit performs independent reviews of the application of operational risk management practices and methodologies and reports to the Examining and Audit Committee of the Board.

State Street’s internal control environment is designed to provide a sound operational environment. The Corporation’s discipline in managing operational risk provides the structure to identify, evaluate, control, monitor, measure, mitigate and report operational risk.

CRITICAL ACCOUNTING ESTIMATES

Critical accounting estimates are those that require management, in the preparation of consolidated financial statements, to make difficult, subjective or complex judgments in the application of certain accounting policies, often as a result of the need to make estimates about the effect of matters that are inherently uncertain and may change in subsequent periods.

State Street’s significant accounting policies were described in detail in Note 1 to the Consolidated Financial Statements in State Street’s Annual Report on Form 10-K for the year ended December 31, 2004. State Street’s critical accounting estimates were described in Management’s Discussion and Analysis of Financial Condition and Results of Operations in its Annual Report on Form 10-K for the year ended December 31, 2004. There were no significant changes in the first nine months of 2005, in the factors or methodology used by management in determining its critical accounting estimates, that were material in relation to the Corporation’s consolidated financial condition, changes in financial condition and results of operations.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The information required by this item is included in the “Risk Management—Market Risk” section of this Discussion and Analysis. State Street’s market risk management function was described in detail in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2004.

23

CONTROLS AND PROCEDURES

The Corporation has established and maintains disclosure controls and procedures that are designed to ensure that material information relating to the Corporation and its consolidated subsidiaries required to be disclosed by the Corporation in the reports that it files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the Corporation’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. For the period covered in this report, the Corporation carried out an evaluation, under the supervision and with the participation of the Corporation’s management, including the Corporation’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Corporation’s disclosure controls and procedures as of the end of the fiscal quarter. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Corporation’s disclosure controls and procedures were effective as of September 30, 2005.

The Corporation has also established and maintains internal control over financial reporting as a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with accounting principles generally accepted in the United States. In the ordinary course of business, the Corporation routinely enhances its internal controls and procedures for financial reporting by either upgrading its current systems or implementing new systems. Changes have been made and will be made to the Corporation’s internal controls and procedures for financial reporting as a result of these efforts. For the period covered in this report, the Corporation carried out an evaluation, under the supervision and with the participation of the Corporation’s management, including the Corporation’s Chief Executive Officer and Chief Financial Officer, of any change in the Corporation’s internal control over financial reporting that occurred during the period covered by the report that has materially affected, or is reasonably likely to materially affect, the Corporation’s internal control over financial reporting. The Chief Executive Officer and Chief Financial Officer have concluded that there was no change in the Corporation’s internal control over financial reporting identified in connection with the evaluation described in this paragraph that has materially affected, or is reasonably likely to materially affect, the Corporation’s internal control over financial reporting.

In the opinion of management, all adjustments, consisting only of normal recurring adjustments, which are necessary for a fair statement of the results of operations in these financial statements, have been made. The preparation of financial statements requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Results of operations for the three and nine months ended September 30, 2005 are not necessarily indicative of the results that may be expected for the year ending December 31, 2005. Certain amounts reported in prior periods have been reclassified to conform to current period classifications.

The Consolidated Statement of Condition at December 31, 2004, has been developed from the audited financial statements at that date, but does not include all footnotes required by U.S. generally accepted accounting principles for a complete set of financial statements. The interim consolidated financial statements and accompanying notes should be read in conjunction with the financial information included in State Street’s 2004 Annual Report on Form 10-K and first and second quarter 2005 Forms 10-Q.

Stock-Based Compensation

Effective January 1, 2003, State Street adopted the fair-value accounting provisions of Statement of Financial Accounting Standards (“SFAS”) No. 123, “Accounting for Stock-Based Compensation,” and elected to use the prospective transition method afforded under SFAS No. 148, “Accounting for Stock-Based Compensation—Transition and Disclosure,” an amendment to SFAS No. 123. Under fair-value accounting, compensation cost for stock options and awards is measured at the grant date based on the fair value of the award and is recognized as expense on a straight-line basis over the service period of the award.

Accounting Changes and Recent Accounting Developments

In December 2004, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 123 (revised 2004), “Share-Based Payment” (“SFAS No. 123-R”), which is a revision of SFAS No. 123. The standard requires that the fair value of all share-based payments to employees be recognized in the consolidated statement of income. In April 2005, the FASB provided for a phased-in implementation of SFAS No. 123-R. Under this revised guidance, the effective date for application of SFAS No. 123-R has been postponed from July 1, 2005 to January 1, 2006. State Street expects to adopt SFAS No. 123-R using the modified prospective method, which requires the recognition of compensation expense over the remaining vesting period for the portion of outstanding stock awards not fully vested as of January 1, 2006. State Street does not expect the adoption of SFAS No. 123-R to have a significant impact on its consolidated financial position or results of operations because the majority of outstanding stock awards have been expensed through September 30, 2005.

Note 2—Acquisitions and Divestitures

In September 2005, the Corporation committed to a plan to divest its ownership interest in Bel Air Investment Advisors LLC (“Bel Air”). As a result, the Corporation realigned its business line organizational and reporting structure for Bel Air and recorded a pre-tax charge of $165 million in the third quarter of 2005, consisting of a $144 million write-off of goodwill associated with the original investment; $10 million of adjustments to write down Bel Air’s tangible assets to fair value and record related estimated selling costs; $8 million related to legal indemnification, and $3 million of other costs. The Corporation also recorded a tax benefit of $58 million in connection with the charge. The charge and related tax benefit are presented separately in the accompanying consolidated statement of income as discontinued operations. Bel Air’s results of operations for current and prior periods have not been reclassified to discontinued operations because these results are not material to those of the consolidated Corporation.

In October 2003, State Street completed the sale of its Private Asset Management (“PAM”) business. Under the terms of the agreement, the transaction was valued at $365 million, of which approximately five percent was subject to the successful transition of the business. State Street recorded a pre-tax gain of $285 million on the sale in 2003. During the third quarter of 2005, as a result of the achievement of certain target levels of client conversions to the buyer, State Street recognized an additional gain of $16 million from final settlement of the sale.

In July 2002, State Street completed the purchase of International Fund Services, a provider of fund accounting and other services to hedge funds. Under the terms of the agreement, State Street was required to make additional payments if certain performance measures were met. During the second quarter of 2005, State Street recorded an additional $42 million payment as goodwill in connection with the final settlement, which occurred in the third quarter of 2005.

Stock Purchase Program

In 1995, State Street’s Board of Directors (the “Board”) authorized the purchase of State Street common stock for use in employee benefit programs and for general corporate purposes. Under this authorization, a total of 2.9 million shares were purchased during the first quarter of 2005. In February 2005, the 1995 stock purchase program was terminated, and in its place, the Board authorized a new, publicly-announced stock purchase program, allowing for the purchase of a total of 15 million shares. Under the 2005 program, 2.2 million shares and 3.1 million shares were purchased during the second and third quarters of 2005, respectively, and the remaining purchase authorization as of September 30, 2005, was 9.7 million shares. The Corporation utilizes third-party broker-dealers to acquire common shares on the open market in its execution of the stock purchase program.

Earnings per Share:
Basic	$.43	$.52	$1.78	$1.83
Diluted	.43	.52	1.76	1.80

(1)Amounts represent stock options outstanding but not included in the computation of diluted average shares because the exercise prices of the instruments were greater than the average fair value of State Street’s common stock during those periods.

Note 12—Contingencies

In the normal course of its business, State Street holds assets under custody and management in a fiduciary or custodial capacity. Management conducts regular reviews of its responsibilities in this regard and considers the results in preparing its consolidated financial statements. In the opinion of management, no contingent liabilities existed at September 30, 2005 that would have had a material adverse effect on State Street’s consolidated financial position or results of operations.

In the normal course of its business, State Street is subject to challenges from U.S. and non-U.S. tax authorities regarding the amount of taxes due. These challenges may result in adjustments to the timing or amount of taxable income or deductions or the allocation of income among tax jurisdictions. During the third quarter of 2004, the U.S. Internal Revenue Service (the “IRS”) completed its review of State Street’s federal income tax returns for tax years 1997, 1998 and 1999 and proposed to disallow tax deductions related to lease-in-lease-out (“LILO”) transactions. State Street believes that it reported the tax effects of these transactions properly, based on applicable statutes, regulations and case law in effect at the time they were entered into.

The IRS has indicated that it will consider settling leasing disputes such as these with taxpayers. State Street filed an appeal with the IRS during the second quarter of 2005. While it is unclear whether State Street will be able to reach an acceptable settlement, management believes the Corporation is appropriately accrued for tax exposures, including exposures related to LILO transactions, and related

interest expense. If State Street prevails in a matter for which an accrual has been established, or is  required to pay an amount exceeding its reserve, the financial statement impact will be reflected in the period in which the matter is resolved.

During the first quarter of 2005, the IRS announced that it had classified SILO (“sale-in-lease-out”) transactions as tax shelters, or “listed transactions.” The IRS began its review of State Street’s tax returns for the years 2000 - 2003 during the second quarter of 2005, and is reviewing State Street’s SILO transactions for these years. State Street believes that it reported the tax effects of these transactions properly, based on applicable statutes, regulations and case law in effect at the time they were entered into.

During the third quarter of 2005, the FASB issued a proposed FASB Staff Position (“FSP”) for comment addressing accounting for changes in tax-related cash flows of leveraged leases. The FSP would require the recalculation of the allocation of income over the lease term when there is a change in the expected timing of tax-related cash flows of a leveraged lease. The proposed FSP, if finalized, will amend SFAS No. 13, “Accounting for Leases,” and will require companies to record any charge resulting from adoption of the FSP as the cumulative effect of a change in accounting principle. The comment period for the proposed FSP closed September 12, 2005, and a final FSP is expected to be issued by the end of 2005.

State Street is currently reviewing the potential impact of this proposed FSP in light of the above-mentioned leasing transactions. Depending on the ultimate requirements of the final FSP and the timing of its issuance and effective date, the FSP may require a material cumulative charge to income in the fourth quarter of 2005. However, future income would be expected to increase over the remaining terms of the leases by an amount approximately equal to the charge, exclusive of any tax-related interest and penalties that may be included in the charge.

During the third quarter of 2005, the FASB also issued for comment a proposed interpretation, “Accounting for Uncertain Tax Positions—an Interpretation of FASB SFAS No. 109,” which attempts to clarify the criteria for recognition of uncertain tax benefits. Adoption of the proposed interpretation in its present form would be recorded as the cumulative effect of a change in accounting principle. The comment period for the proposed interpretation closed September 12, 2005, and a final interpretation is not expected to be issued until the first quarter of 2006. State Street is currently reviewing the impact of the proposed guidance.

In the normal course of its business, State Street uses derivative financial instruments to support clients’ needs, conduct trading activities, and manage its interest rate and foreign currency risks. The Corporation takes positions in both the foreign exchange and interest rate markets by buying and selling cash instruments and using financial derivatives, including foreign exchange contracts and interest-rate options, swaps, caps and futures. Interest rate contracts involve an agreement with a counterparty to exchange cash flows based on the movement of an underlying interest rate index. Foreign exchange contracts involve an agreement to exchange one currency for another currency at an agreed-upon rate and settlement date. The use of these instruments impacts fee revenue and net interest revenue.

Trading:
Interest rate contracts:
Swap agreements		$	3,939		$	1,450

Futures		354			—
Balance Sheet Management:
Interest rate contracts:
Swap agreements		5,054			4,300
Foreign exchange contracts:
Forward, swap and spot		360			407

In connection with its balance sheet management activities, State Street has executed interest-rate swap agreements designated as fair-value and cash-flow hedges to manage interest-rate risk related to its securities available for sale, interest-bearing time deposits and long-term debt. The contractual rates versus weighted average rates for these financial instruments, including the effects of hedge instruments, were as follows for the periods indicated:

	Three Months Ended September 30, 2005						Nine Months Ended September 30, 2005
	Contractual Rates			Rate Including Impact of Hedges			Contractual Rates			Rate Including Impact of Hedges
Interest-bearing time deposits		3.58	%		3.37	%		3.01	%		3.15	%
Long-term debt		6.60			5.71			6.49			5.39

During 2004, State Street entered into forward foreign currency swaps with a notional value of €300 million, or approximately US$360 million at September 30, 2005, to hedge its net investment in certain non-U.S. subsidiaries and manage the volatility in shareholders’ equity that results from translation gains and losses. As a result, translation losses for the three and nine months ended September 30, 2005 were offset by after-tax gains of $2 million and $32 million, respectively, on the hedge contracts, which gains were recorded as a component of shareholders’ equity.

Note 14—Commitments and Off-Balance Sheet Activities

Credit-related financial instruments include indemnified securities on loan, unfunded commitments to extend credit or purchase assets and standby letters of credit. The total potential loss on unfunded commitments, standby letters of credit and securities lending indemnifications is equal to the total contractual amount, which does not consider the value of any collateral.

The following is a summary of the contractual amount of State Street’s credit-related, off-balance sheet financial instruments at the dates indicated:

(Dollars in millions)	September 30, 2005			December 31, 2004
Indemnified securities on loan		$	374,241		$	349,543
Liquidity asset purchase agreements		23,579			20,410
Unfunded commitments to extend credit		13,712			12,731
Standby letters of credit		5,128			4,784

On behalf of its clients, State Street lends their securities to creditworthy brokers and other institutions. In certain circumstances, State Street may indemnify its clients for the fair market value of those securities against a failure of the borrower to return such securities. Collateral funds received in connection with State Street securities lending services are held by State Street as agent and are not assets of the Corporation. State Street requires the borrowers to provide collateral in an amount equal to or in excess of 102% of the fair market value of the securities borrowed. The borrowed securities are revalued daily to determine if additional collateral is necessary. State Street held, as agent, cash and U.S. government securities totaling $388.67 billion and $360.61 billion as collateral for indemnified securities on loan at September 30, 2005 and December 31, 2004, respectively.

Approximately 84% of the unfunded commitments to extend credit and liquidity asset purchase agreements expire within one year from the date of issue. Since many of the commitments are expected to expire or renew without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.

In the normal course of its business, State Street provides liquidity and credit enhancements to asset-backed commercial paper programs which are special purpose entities (“SPEs”). These SPEs, which are administered by State Street and are not included in the Corporation’s consolidated statement of condition, may purchase financial assets directly, or make loans or invest in debt securities secured by financial assets. The SPEs finance their activities through the issuance of rated commercial paper to third-party investors, including State Street’s custodial clients.

The commercial paper issuances and commitments of the SPEs to provide funding are supported by liquidity asset purchase agreements and backup liquidity lines of credit, the majority of which are provided by State Street. In addition, State Street provides direct credit support to the SPEs in the form of standby letters of credit. State Street’s commitments under liquidity asset purchase agreements and backup lines of credit totaled $16.26 billion at September 30, 2005, all of which is included in the foregoing table. State Street’s commitments under standby letters of credit totaled $631 million at September 30, 2005, which is also included in the foregoing table.

Note 14—Commitments and Off-Balance Sheet Activities (Continued)

Asset performance deterioration or certain other factors may shift the asset risk from the commercial paper investors to the Corporation as the liquidity or credit enhancement provider. In addition, the SPEs may need to draw upon the backup facilities to repay maturing commercial paper. In these instances, State Street would either acquire the assets of the SPEs at fair market value on the date of transfer, or make loans to the SPEs secured by the SPEs’ assets. Potential losses, if any, from these SPEs are not expected to materially affect the Corporation’s consolidated financial condition or results of operations.

In the normal course of its business, State Street structures and sells partnership interests in pools of tax-exempt investment-grade assets to mutual fund clients, utilizing qualified special-purpose entities (“QSPEs”), which are not included in the Corporation’s consolidated statement of condition. Typically, State Street transfers assets to the QSPEs from its investment portfolio at fair market value, and treats such transfers as sales. The QSPEs finance the acquisition of these assets by selling partnership interests to third-party investors. During the nine months ended September 30, 2005, State Street sold $1.49 billion of investment securities to these QSPEs, and at September 30, 2005, owned a minority residual interest in these QSPEs of less than 12 %, or $247 million, compared to less than 7%, or $156 million, at December 31, 2004. At September 30, 2005, these QSPEs had total assets of $2.23 billion, compared to $2.18 billion at December 31, 2004. The QSPEs had a weighted average life of approximately 6.0 years at September 30, 2005, compared to approximately 5.4 years at December 31, 2004.

Under separate agreements, State Street provides liquidity asset purchase agreements to these QSPEs, which obligate the Corporation to buy the partnership interests in the underlying portfolio at par value, which approximates fair market value, in the event that the re-marketing agent is unable to place the partnership interests of the QSPEs with investors. The liquidity asset purchase agreements are subject to early termination by State Street in the event of a shortfall in the required over-collateralization in the QSPE. The liquidity asset purchase agreement provider is not obligated to repurchase bonds in the event of the following credit events: payment default, bankruptcy of issuer or credit enhancement provider, taxability, or downgrade of an asset below investment grade. The Corporation’s commitments to the QSPEs under liquidity asset purchase agreements totaled $1.92 billion at September 30, 2005, none of which was utilized at period-end, and all of which was included in the foregoing table.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Shareholders and Board of Directors
State Street Corporation

We have reviewed the condensed consolidated statement of condition of State Street Corporation as of September 30, 2005, and the related condensed consolidated statements of income for the three-month and nine-month periods ended September 30, 2005 and 2004, and the condensed consolidated statements of changes in shareholders’ equity and cash flows for the nine-month periods ended September 30, 2005 and 2004. These financial statements are the responsibility of the Corporation’s management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the condensed consolidated interim financial statements referred to above for them to be in conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated statement of condition of State Street Corporation as of December 31, 2004, and the related consolidated statements of income, changes in shareholders’ equity, and cash flows for the year then ended not presented herein, and in our report dated February 17, 2005, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated statement of condition as of December 31, 2004, is fairly stated, in all material respects, in relation to the consolidated statement of condition from which it has been derived.
