State Street Reports EPS of $3.79 for Full Year 2011, up 23% Compared to $3.09 for Full Year 2010 on a Revenue Increase of 7%

Operating-Basis⁽¹⁾ Earnings Per Share of $3.73 Increased 10% from $3.40 in 2010

BOSTON--(BUSINESS WIRE)--January 18, 2012--State Street Corporation today announced full-year and fourth-quarter 2011 earnings per common share of $3.79 and $0.76, respectively, compared to full-year and fourth-quarter 2010 earnings per share of $3.09 and $0.16, respectively.

Revenue of $9.594 billion in full-year 2011 increased 7% from $8.953 billion in 2010 and expenses were $7.058 billion, up 3% from $6.842 billion in 2010. Return on average common shareholders’ equity was 10.0% in 2011 and 9.5% in 2010.

Fourth-quarter 2011 revenue of $2.315 billion increased 13% from $2.043 billion in the fourth quarter of 2010 and decreased 5% from $2.427 billion in the third quarter of 2011. Expenses of $1.784 billion compared to $1.792 billion in the fourth quarter of 2010 and decreased 1% from $1.798 billion in the third quarter of 2011. Earnings per common share in the fourth quarter of 2011 were $0.76, up from $0.16 in the fourth quarter of 2010 (which reflected the effects of a fourth-quarter 2010 investment portfolio repositioning and separate fourth-quarter 2010 restructuring charges) and down from $1.10 in the third quarter of 2011. Return on average common shareholders’ equity was 7.8% for the fourth quarter of 2011, compared to 1.8% for the fourth quarter of 2010 and 11.2% for the third quarter of 2011.

Consistent with its previously announced program, State Street recorded $58 million ($0.08 per share) of pre-tax charges during the fourth quarter associated with its business operations and information technology transformation program.

Fourth-quarter 2011 results also reflected additional expense control measures designed to better calibrate the Company’s expenses to its outlook for its capital markets-facing businesses in 2012, which resulted in pre-tax charges of $120 million ($0.15 per share). The majority of these charges related to our withdrawal from our fixed-income trading initiative, and the remaining costs were associated with severance and benefits costs for targeted staff reductions.

Joseph L. Hooley, State Street's chairman, president and chief executive officer, said, “Overall, 2011 was a very successful year amid extremely challenging market conditions. Revenue in the year was characterized by a strong first half followed by a weaker second half, the result of volatile markets and risk-averse investor behavior. Despite these conditions, comparing 2011 with 2010, we were able to achieve strong growth in both revenue and earnings per share.”

He continued, “Our focus on delivering for our clients continues to drive new opportunities for us. In 2011 we won mandates for $1.4 trillion in assets to be serviced, $270 billion of which are scheduled for installation in 2012. State Street Global Advisors (SSgA) continues to benefit from growth in ETF assets, adding 32 new ETF strategies in 2011.”

Hooley added, “Our results for 2011 also demonstrated the positive impact of the expense controls we put in place, especially the progress of the business operations and information technology transformation program, relative to compensation and employee benefits expenses. We will continue to manage our expenses in 2012 to address the impact of challenging capital markets.”

Hooley concluded, “We remain committed to delivering long-term value to our shareholders and maintaining our strong capital position. In the fourth quarter of 2011, we purchased approximately 5.6 million shares of our common stock, which brought the total shares purchased in 2011 to 16.3 million. We ended the fourth quarter with a tier 1 common ratio of 16.9%. We submitted our 2012 capital plan to the Federal Reserve Bank earlier this month as required, and we continue to prioritize increasing return of capital to shareholders through dividends and our share repurchase program.”

NON-GAAP FINANCIAL MEASURES

In addition to presenting State Street’s financial results in conformity with U.S. generally accepted accounting principles (GAAP), management also presents results on a non-GAAP basis, to which management refers as “operating basis,” in order to highlight comparable financial trends and other characteristics with respect to State Street’s ongoing business operations from period to period. Reconciliations of operating-basis results to GAAP-basis results are provided in the addendum included in this news release. The “Additional Information” section of this news release provides further information about operating-basis financial measures.

Operating-basis earnings per common share in full-year 2011 were $3.73, up 10% from $3.40 in 2010 on $9.502 billion in operating-basis revenue, an increase of 9% from operating-basis revenue of $8.714 billion in 2010. Operating-basis expenses were $6.789 billion, an increase of 10 percent from operating-basis expenses of $6.176 billion in 2010. Return on average common shareholders’ equity on an operating basis in 2011 was 9.9%, down from 10.4% in 2010.

Operating-basis earnings per common share in the fourth quarter of 2011 were $0.93, compared to $0.87 in the fourth quarter of 2010 and $0.96 in the third quarter of 2011. Operating-basis revenue of $2.286 billion in the fourth quarter of 2011 was approximately flat with $2.281 billion in the fourth quarter of 2010 and declined 5% from $2.413 billion in the third quarter of 2011. Operating-basis expenses of $1.636 billion increased 1% from $1.624 billion in the fourth quarter of 2010 and decreased 5% from $1.713 billion in the third quarter of 2011. On an operating basis, fourth-quarter 2011 return on average common shareholders’ equity was 9.5%, down from 9.8% in both the fourth quarter of 2010 and the third quarter of 2011.

The table below provides a summary of selected financial information and key ratios for the indicated periods, presented on an operating (non-GAAP) basis where noted. Amounts are presented in millions of dollars, except for per-share amounts or where otherwise noted.

⁽¹⁾ Presented on an operating basis, a non-GAAP presentation. Refer to reconciliations of this operating-basis information to its GAAP-basis equivalent in the addendum included in this news release.

⁽²⁾ Includes assets under custody of $15.863 trillion, $15.714 trillion, and $15.860 trillion, respectively, as of period end Q4 2011, Q3 2011 and Q4 2010.

⁽³⁾ Unless otherwise specified, all capital ratios referenced in the table above and elsewhere in this news release refer to State Street Corporation and not State Street Bank and Trust Company. See the “Additional Information” section of this news release for a further description of these ratios, and the addendum included in this news release for reconciliations applicable to the tier 1 common and TCE ratios presented in this table.

Total assets were $216 billion and $209 billion and included $50 billion and $34 billion of excess deposits held at the Federal Reserve and other central banks at December 31, 2011 and September 30, 2011, respectively. The average balance sheet for the fourth quarter of 2011 was $195 billion, compared to $160 billion for the fourth quarter of 2010 and $181 billion for the third quarter of 2011. State Street’s regulatory capital ratios continue to be strong as of December 31, 2011, with the Company’s total capital ratio at 20.5%, its tier 1 capital ratio at 18.9% and its tier 1 leverage ratio at 7.3%. In addition, as of December 31, 2011, the Company’s tier 1 common ratio was 16.9%, its TCE ratio was 7.3%, and its TCE to risk-weighted assets ratio was 16.0%. December 31, 2011 ratios adjusted for the effects of the applicable methodologies provided for in the Basel III capital requirements are: total capital ratio of 14.9%, tier 1 capital ratio of 13.3%, tier 1 leverage ratio of 5.6%, and tier 1 common ratio of 12.1%. These ratios reflect State Street’s estimates of the impact of the requirements under Basel III affecting capital, based upon published statements of the Basel Committee and the Federal Reserve. See “Additional Information” included in this news release for information concerning the specified capital ratios and the addendum at the end of this news release for reconciliations of these ratios to ratios calculated under presently applicable requirements.

At December 31, 2011, the net after-tax unrealized mark-to-market losses in the investment portfolio were $374 million, an increase from net unrealized mark-to-market losses of $259 million at September 30, 2011, primarily due to a widening in spreads on securities, but down from $504 million as of December 31, 2010, primarily due to lower rates.

The Company expects to record aggregate pre-tax conduit-related accretion of approximately $1.1 billion in interest revenue from January 1, 2012 through the remaining terms of the former conduit securities. This expectation is based on numerous assumptions, including holding the securities to maturity, anticipated pre-payment speeds, credit quality and sales.

The following tables provide the components of operating-basis revenue and operating-basis expenses for the periods noted:

Operating-Basis Revenue (non-GAAP)⁽¹⁾

⁽¹⁾ Net Interest revenue for the fourth and third quarters of 2011 and the fourth quarter of 2010, presented in the table, included $32 million, $32 million and $33 million, respectively, of tax-equivalent adjustments, and excluded $61 million, $46 million and $139 million, respectively, of conduit-related discount accretion. GAAP-basis net interest revenue for these periods was $606 million, $578 million and $656 million, respectively.

FOURTH-QUARTER 2011 RESULTS VS. FOURTH-QUARTER 2010

Servicing fees were down 1% to $1.057 billion from $1.064 billion in the fourth quarter of 2010. The decrease reflected clients’ de-risking strategies amid the turmoil in European markets and the uncertainty in emerging market economies, offset partially by new business and a slight increase in the S & P 500. Total assets under custody and administration were $21.807 trillion at December 31, 2011, up 1% compared with $21.527 trillion at December 31, 2010. Daily average values for the S & P 500 Index and the MSCI^® EAFE Index^ES were up approximately 2% and down approximately 12%, respectively, from the fourth quarter of 2010.

Investment management fees, generated by State Street Global Advisors, were $202 million, down 9% from $221 million in the fourth quarter of 2010. The decrease in management fees reflected outflows in cash, fixed income, and active equities, amid the turmoil in Europe, offset partially by the impact of an acquisition. Total assets under management at December 31, 2011, were $1.866 trillion, down 7% compared to $2.010 trillion at December 31, 2010 reflecting de-risking behavior by clients redeeming from international and emerging markets strategies as well as the scheduled redemptions by the U.S. Department of the Treasury. Average month-end equity valuations for the S & P 500 Index and the MSCI^® EAFE Index^ES were up approximately 4% and down approximately 10%, respectively, from the fourth quarter of 2010.

Trading services revenue, which includes foreign exchange trading revenue and brokerage and other fees, was $273 million for the fourth quarter of 2011, a decrease of 12% from $310 million in the fourth quarter of 2010. Foreign exchange trading revenue decreased 12% primarily due to a shift in mix. Brokerage and other fees were down 12% due to weaker revenue from transition management.

Securities finance revenue was $90 million in the quarter, up 30% from $69 million in the fourth quarter of 2010, due primarily to improved spreads, offset partially by lower volumes. Processing fees and other revenue was $45 million, down 37% from $71 million due to fair-value adjustments relative to positions in the fixed-income trading initiative.

Net interest revenue on a fully taxable-equivalent basis, including conduit-related discount accretion, was $638 million in the fourth quarter of 2011, compared to $689 million in the fourth quarter of 2010. On an operating basis, excluding discount accretion, net interest revenue was $577 million, an increase of 5% from $550 million in the fourth quarter of 2010 primarily due to an increase in deposit volumes as well as lower deposit costs, offset partially by lower asset yields on the investment portfolio. Clients placed additional deposits with State Street during the fourth quarter of 2011, which were invested with central banks, the impact of which contributed to a lower net interest margin than otherwise would have been achieved. Including this unusually high level of deposits, fully taxable-equivalent net interest margin, including the discount accretion, was 155 basis points in the fourth quarter of 2011 compared to 207 basis points in the fourth quarter of 2010. Operating-basis net interest margin, including the excess central bank deposits, was 140 basis points in the fourth quarter of 2011 and excluding the excess deposits was 158 basis points, compared to 165 basis points in the fourth quarter of 2010.

In the fourth quarter of 2011, we recorded $59 million of net gains from sales of available-for-sale securities and, separately, $17 million of net losses from other-than-temporary impairment, resulting in $42 million of net gains related to investment securities.

Operating-basis expenses of $1.636 billion in the fourth quarter of 2011 increased 1% compared to the fourth quarter of 2010. Compensation and employee benefits expenses decreased 7% from $935 million to $872 million, primarily due to lower incentive compensation and the benefits from the implementation of the business operations and information technology transformation program, offset partially by the impact of acquisitions and merit adjustments. Transaction processing services expenses were up 5% to $179 million from $171 million due to higher volumes in investment servicing. Other expenses increased 30%, or $64 million, to $274 million, primarily due to increased fees for professional services and higher securities processing costs.

The effective tax rate on fourth-quarter 2011 GAAP-basis earnings was 28.3%, down from 67.2% in the fourth quarter of 2010 due primarily to the repositioning of the investment portfolio in the fourth quarter of 2010. The effective tax rate on operating-basis earnings for the fourth quarter of 2011 was 25.0%, down from 29.5% in the fourth quarter of 2010 due primarily to the geographic mix of pre-tax income and a reduction of deferred tax liabilities. The 2011 full-year effective tax rate on GAAP-basis earnings was 24.3% and the full-year effective tax rate on operating-basis earnings was 26.9%. Our effective tax rate on operating-basis earnings for the full year 2012 is expected to be in the range of 27% to 28%.

FOURTH-QUARTER 2011 RESULTS VS. THE THIRD-QUARTER 2011

Servicing fees were $1.057 billion, down 4% from $1.106 billion in the third quarter. The decrease is consistent with clients’ de-risking decisions amid the turmoil in Europe and uncertainties in emerging markets, the impact of foreign exchange and lower equity market valuations. Daily average values as measured by the S & P 500 were flat and as measured by the MSCI^® EAFE Index^ES were down about 7%. Management fees were $202 million, down 12% from $229 million. The decrease in management fees reflected outflows in cash, fixed income, and active equities, amid the turmoil in Europe. Average month-end equity valuations as measured by the S & P 500 were up about 3% and as measured by the MSCI^® EAFE Index^ES were down about 5%. Trading services revenue, which includes foreign exchange trading and brokerage and other fees, was $273 million, down 18% from $334 million. Foreign exchange trading revenue of $150 million decreased 26% due primarily to weaker volumes as well as lower volatility. Brokerage and other fee revenue was $123 million, down 5% from the third quarter due to lower revenue from transition management. Securities finance revenue was $90 million, up 6% from $85 million, primarily due to higher spreads offset slightly by lower volumes. Processing fees and other revenue was down 50% to $45 million due to fair-value adjustments relative to positions in the fixed-income trading initiative.

Fully taxable-equivalent net interest revenue in the fourth quarter of 2011 totaled $638 million, including discount accretion, compared to $610 million in the third quarter. On an operating basis, fully taxable-equivalent net interest revenue in the fourth quarter of 2011 excluding discount accretion was $577 million, up 2% from $564 million in the third quarter due to an increase in earning assets driven by the high levels of client deposits.

Compared to the third quarter of 2011, compensation and employee benefits expenses decreased 10% to $872 million from $965 million, due to savings achieved partially from the business operations and information technology transformation program and reductions in incentive compensation. Other expenses were $274 million, an increase of 6% from $258 million in the third quarter due primarily to increases in fees for professional services.

ADDITIONAL INFORMATION

All per share amounts represent fully diluted earnings per common share. Return on average common shareholders’ equity is determined by dividing full-year or annualized net income available to common equity by average common shareholders’ equity for the period. Operating-basis return on average common equity utilizes full-year or annualized operating-basis net income available to common equity in the calculation.

Non-GAAP Financial Measures

This news release includes financial information presented on a GAAP basis as well as on an operating basis. Operating-basis financial information is a non-GAAP presentation. Management measures and compares certain financial information on an operating basis, as it believes that this presentation supports meaningful comparisons from period to period and the analysis of comparable financial trends with respect to State Street’s normal ongoing business operations. Management believes that operating-basis financial information, which reports revenue from non-taxable sources on a fully taxable-equivalent basis and excludes the impact of revenue and expenses outside of the normal course of business, facilitates an investor’s understanding and analysis of State Street’s underlying financial performance and trends in addition to financial information prepared and reported in accordance with GAAP.

This news release also includes capital ratios in addition to, or adjusted from, those calculated in accordance with applicable regulatory requirements. These include capital ratios based on tier 1 common risk-based capital and tangible common equity as well as capital ratios adjusted to reflect our estimate of the impact of the Basel III capital requirements. These non-regulatory and adjusted capital measures are non-GAAP financial measures. Management currently evaluates the non-GAAP capital ratios presented in this news release to aid in its understanding of State Street’s capital position under a variety of standards, including presently applicable and evolving regulatory requirements. Management believes that the use of the non-GAAP capital ratios described in this news release similarly aids in an investor's understanding of State Street's capital position and therefore is of interest to investors.

In addition to the reconciliations, described below, of the capital ratios referenced in this news release, the addendum included in this news release also includes reconciliations of the following other non-GAAP financial measures referenced in this news release: operating-basis results to GAAP-basis results and Basel III-adjusted capital ratios to capital ratios calculated under currently applicable requirements.

Non-GAAP financial measures should be considered in addition to, not as a substitute for or superior to, financial measures determined in accordance with GAAP and capital ratios determined in accordance with currently applicable regulatory requirements.

Capital Ratios

The total capital, tier 1 risk-based capital, or tier 1 capital, and tier 1 leverage ratios are capital ratios used regularly by bank regulatory authorities to evaluate the Company’s capital adequacy. The tier 1 risk-based common, or tier 1 common, ratio is sometimes used by the Federal Reserve in connection with its capital assessment and review programs. The tangible common equity, or TCE, and TCE/risk-weighted assets, or RWA, ratios are other capital ratios management believes provide additional context for understanding and assessing the Company’s capital adequacy.

• The total capital, tier 1 capital, and tier 1 leverage ratios, as applicable, are each calculated in accordance with applicable bank regulatory requirements.
• The tier 1 common ratio is calculated by dividing (a) tier 1 capital less non-common elements including qualifying perpetual preferred stock, qualifying minority interest in subsidiaries and qualifying trust preferred securities, by (b) total risk-weighted assets, which assets are calculated in accordance with applicable bank regulatory requirements. The tier 1 common ratio is not required by GAAP or on a recurring basis by bank regulations. Management is currently monitoring this ratio, along with the other capital ratios described in this news release, in evaluating State Street’s capital levels and believes that, at this time, the ratio may be of interest to investors. Reconciliations with respect to the tier 1 common ratios as of December 31, 2011, September 30, 2011, and December 31, 2010 are provided in the addendum included in this news release.
• The TCE ratio is calculated by dividing consolidated total common shareholders’ equity by consolidated total assets, after reducing both amounts by goodwill and other intangible assets net of related deferred taxes. Total assets reflected in the TCE ratio also exclude cash balances on deposit at the Federal Reserve Bank and other central banks in excess of required reserves. The TCE ratio is not required by GAAP or by bank regulations, but is a metric used by management to evaluate the adequacy of State Street’s capital levels. Since there is no authoritative requirement to calculate the TCE ratio, our TCE ratio is not necessarily comparable to similar capital measures disclosed or used by other companies in the financial services industry. Tangible common equity and adjusted tangible assets are non-GAAP financial measures and should be considered in addition to, not as a substitute for or superior to, financial measures determined in accordance with GAAP. Reconciliations with respect to the calculation of the TCE ratio as of December 31, 2011, September 30, 2011, and December 31, 2010 are provided in the addendum included in this news release.
• The TCE/RWA ratio is calculated by dividing consolidated total common shareholders’ equity (reduced by goodwill and other intangible assets net of related deferred taxes) by total risk-weighted assets (determined in accordance with applicable bank regulatory requirements). The TCE/RWA ratio is not required by GAAP or by bank regulations, but is a metric used by management to evaluate the adequacy of State Street’s capital levels. Since there is no authoritative requirement to calculate the TCE/RWA ratio, our TCE/RWA ratio is not necessarily comparable to similar capital measures disclosed or used by other companies in the financial services industry. Tangible common equity is a non-GAAP financial measure and should be considered in addition to, not as a substitute for or superior to, financial measures determined in accordance with GAAP. Reconciliations with respect to the calculation of the TCE/RWA ratio as of December 31, 2011, September 30, 2011, and December 31, 2010 are provided in the addendum included in this news release.

⁽¹⁾ Actual (unaudited) total capital, tier 1 capital and tier 1 leverage ratios were calculated in accordance with currently applicable bank regulatory requirements. Tier 1 common ratio was calculated by dividing (a) tier 1 capital less non-common elements including qualifying perpetual preferred stock, qualifying minority interest in subsidiaries and qualifying trust preferred securities (tier 1 common capital), by (b) total risk-weighted assets, which were calculated in accordance with currently applicable bank regulatory requirements.

⁽²⁾ For purposes of the calculations in accordance with Basel III (see below), total capital, tier 1 capital and tier 1 leverage ratios, total risk-weighted assets and adjusted quarterly average assets were calculated based on State Street’s estimates, based on published statements of the Basel Committee and the Federal Reserve, of the effects of the requirements under Basel III affecting capital. The tier 1 common ratio was calculated by dividing (a) tier 1 common capital (as described in footnote ⁽¹⁾), but with tier 1 capital calculated in accordance with Basel III by, (b) total risk-weighted assets, which are calculated in accordance with Basel III. State Street calculates its capital ratios in accordance with the requirements of the Board of Governors of the Federal Reserve System, which has not yet adopted Basel III. There remains considerable uncertainty concerning the timing for adoption and implementation of Basel III by the Federal Reserve. When adopted, the Federal Reserve may implement Basel III with some or more modifications or adjustments. Therefore, State Street’s current understanding of Basel III, as reflected in the table above, may be different from the ultimate application of Basel III by the Federal Reserve to State Street.

• Tier 1 capital used in the calculation of the tier 1 capital and tier 1 leverage ratios decreased by $595 million, as a result of applying estimated Basel III requirements to tier 1 capital of $13.625 billion as of December 31, 2011. Total capital used in the calculation of the total capital ratio decreased by $141 million, as a result of applying estimated Basel III requirements to total capital of $14.823 billion as of December 31, 2011.

• Tier 1 common capital used in the calculation of the tier 1 common ratio was $11.893 billion, reflecting the adjustments to tier 1 capital described in the first bullet above. Tier 1 common capital used in the calculation is therefore calculated as adjusted tier 1 capital of $13.030 billion less non-common elements of capital, composed of trust preferred securities of $637 million and preferred stock of $500 million as of December 31, 2011, resulting in tier 1 common capital of $11.893 billion. At December 31, 2011, there was no qualifying minority interest in subsidiaries.

• Total risk-weighted assets used in the calculation of the total capital, tier 1 capital and tier 1 common ratios increased by $26.101 billion as a result of applying estimated Basel III requirements to total risk-weighted assets of $72.234 billion as of December 31, 2011.

• Consolidated adjusted quarterly average assets used in the calculation of the leverage ratio increased by $45.903 billion as a result of applying estimated Basel III requirements to the actual consolidated adjusted quarterly average assets of $186.021 billion as of December 31, 2011.
