   State Street Reports Fourth-Quarter Earnings Per Share of $.86,
   up 16%; for 2006, Revenue up 15%; EPS from Continuing Operations
              up 14% and up 23% Excluding Q2 Tax Charges


    BOSTON--(BUSINESS WIRE)--Jan. 17, 2007--State Street Corporation
today announced 2006 fourth-quarter earnings per share of $0.86 on net
income of $291 million. Earnings per share increased 16% versus the
2005 fourth quarter's results of $0.74 per share on net income of $249
million. Total revenue of $1.622 billion in the fourth quarter of 2006
is up 15% from $1.416 billion in the fourth quarter a year ago.
Expenses of $1.18 billion are up 13% from $1.04 billion in the
year-ago quarter. For the fourth quarter of 2006, return on
shareholders' equity of 15.9% is flat with the fourth quarter of 2005.

    For the full year, earnings per share from continuing operations
of $3.21 per share, on net income of $1.1 billion, increased 14% from
$2.82 per share from continuing operations in 2005. Earnings per share
in 2006 includes $0.25 per share, or $83 million, of tax charges
recorded in the second quarter. Excluding these charges, earnings per
share from continuing operations would have been $3.46, up 23%, on net
income of $1.2 billion, compared to $2.82 per share from continuing
operations on income from continuing operations of $945 million in
2005. Return on shareholders' equity from continuing operations in
2006 of 16.0 %, or 17.1% excluding the tax charges, compares with
return on equity from continuing operations of 15.3% in 2005.

    Total revenue, on a fully taxable-equivalent basis, is up 15%,
from $5.52 billion in 2005 to a record level of $6.35 billion in 2006.
Operating expenses in 2006 of $4.54 billion increased 12% from $4.04
billion in 2005.

    Commenting on the performance, Ronald E. Logue, State Street's
chairman and chief executive officer, said, "I'm pleased that we
exceeded the financial goals we set for the year, helped by a
favorable operating environment. Nearly every revenue item on our
income statement increased in double digits on a year-over-year basis,
and we achieved positive operating leverage again this year. Our
servicing fees continued strong. Revenue at State Street Global
Advisors, our investment management arm, grew 26% in 2006 compared to
2005, and it is increasingly becoming a more meaningful contributor to
State Street's results. Our strategy of more actively managing the
balance sheet contributed to an annual increase of 21% in fully
taxable-equivalent net interest revenue. Net interest margin equaled
1.24% for 2006. Additionally, our non-U.S. revenue now represents
approximately 43% of total revenue, in line with our long-term goal of
50% over several years."

    Logue concluded, "During 2007 we will build on the progress we
made in 2006, particularly internationally. We continue to target
positive operating leverage on an annual basis. We will continue to
execute against our long-term financial goals of revenue growth of 8%
to 12%, earnings per share growth of 10% to 15%, and return on equity
of 14% to 17%. Our 2007 target is to achieve in the top half of these
ranges."

    FOURTH-QUARTER RESULTS VS. YEAR-AGO QUARTER

    Total revenue of $1.622 billion in the fourth quarter of 2006 is
up from $1.416 billion, or 15%, from the fourth quarter of 2005.

    Servicing fees are $698 million, up $61 million or 10%, from $637
million in the year-ago quarter. The increase is attributable to new
business from existing and new clients and higher equity valuations in
2006. Total assets under custody at quarter end are $11.85 trillion, a
record level, up 17%, compared with $10.12 trillion in the year-ago
quarter.

    Management fees, generated by State Street Global Advisors, are
$253 million, up $40 million, or 19%, compared to $213 million in the
year-ago quarter. The increase in management fees reflects new
business from existing and new clients and higher equity valuations in
2006. Total assets under management at quarter end are at a record
level, $1.7 trillion, up 21%, compared to $1.4 trillion in the
previous year-ago quarter.

    Average month-end values compared to the fourth quarter of 2005,
are up 13% for the S&P 500 Index and up 10% for the NASDAQ; average
month-end values for the MSCI(R) EAFE Index(SM) are up 24%. The total
return of the Lehman US Aggregate bond index for the fourth quarter is
1.24%.

    Trading services revenue, which includes foreign exchange trading
revenue and brokerage services, is up 12%, from $182 million to $203
million. The increase is driven by higher volumes in foreign exchange,
offset partially by lower volatility.

    Securities finance revenue is $90 million in the quarter, compared
to $73 million in the year-ago quarter, an increase of 23%. The
increase primarily reflects improving demand for securities on loan.

    Processing and other revenue is down 14%, or $10 million to $61
million partially due to the third-quarter transfer of tax-exempt
investments onto the balance sheet.

    Fully taxable-equivalent net interest revenue is $325 million, up
28% from $253 million in last year's fourth quarter. The increase is
due to a higher level of customer deposits, a more favorable non-US
rate environment, and a higher level of lower-cost funding.

    Total expenses of $1.18 billion in the fourth quarter of 2006 are
up 13% from expenses of $1.04 billion in the fourth quarter of 2005.
Salaries and employee benefits expenses increased $105 million from
$589 million to $694 million, driven principally by incentive
compensation due to improved performance and a higher headcount.
Transaction processing expense increased slightly to $121 million.
Information systems and communications expense was down slightly at
$119 million. Occupancy expenses of $94 million in 2006 compare to $89
million in 2005. Other expenses increased $29 million to $150 million,
which includes costs to support growth initiatives.

    The effective tax rate was 34.6% in the fourth quarter of 2006
compared with 34% in the fourth quarter of 2005. We expect the rate
for 2007 to be 35.0%.

    FOURTH-QUARTER RESULTS VS. THIRD QUARTER

    Fourth-quarter earnings per share of $0.86 is up 4%, or $0.03,
compared to third quarter earnings per share of $0.83. The
third-quarter results include a cumulative gain of $15 million, or
$0.03 per share, in trading services revenue related to the
Corporation's tax-exempt investment programs. Excluding this gain,
earnings per share would have increased 8%. Total revenue in the
fourth quarter of $1.6 billion is up 7%, or $107 million, or $122
million excluding the cumulative gain in the third quarter, versus
$1.5 billion in the third quarter. Total expenses in the fourth
quarter of $1.2 billion are up $88 million compared to $1.1 billion in
the third quarter.

    Servicing fee revenue is up 2% and management fee revenue is up
6%, both improvements due to higher equity valuations and business
from new and existing customers. Trading services revenue is up 19% to
$203 million due to increased volumes in FX and improved fees from
transition management, offset by lower volatilities in FX trading.
Excluding the impact of the third-quarter $15 million cumulative gain
noted above, the increase would have been 30%. Securities finance
revenue increased 3% to $90 million. Processing fees and other revenue
declined 6% to $61 million due to lower tax-advantaged investment
income. Fully taxable-equivalent net interest revenue increased 18% to
$325 million due to higher levels of customer deposits and lower-cost
funds.

    Salaries and employee benefits expense is up 9% due to increased
incentive compensation expense. Occupancy expense was up 3% due to
higher operating costs. Other expense increased 27%, or $32 million,
to $150 million partially due to higher professional fees to support
growth initiatives.

    FULL YEAR 2006 VS. 2005

    Total revenue on a fully taxable-equivalent basis increased 15%
from $5.52 billion to $6.35 billion. Servicing fees increased 10%,
from $2.47 billion to $2.72 billion. Management fees increased 26%,
from $751 million to $943 million. Trading services revenue increased
24%, from $694 million to $862 million and securities finance revenue
increased 17%, from $330 million to $386 million. Processing fees and
other revenue decreased 10%, to $272 million from $302 million. Fully
taxable-equivalent net interest revenue increased 21%, from $949
million to $1.15 billion.

    Expenses increased 12%, from $4.04 billion to $4.54 billion,
including increases of 19% to $2.65 billion in salaries and employee
benefits expense. Transaction processing expense increased 10% to $496
million and information systems and communications increased 3% to
$501 million. Occupancy expense decreased 5% to $373 million. Other
expenses increased 7% to $518 million.

    ADDITIONAL INFORMATION

    All per share amounts represent diluted earnings per share.

    On January 12, 2007, the IRS released guidance concerning the Tax
Increase Prevention and Reconciliation Act, or "TIPRA". State Street
previously reported a second-quarter 2006 tax-related charge of
approximately $59 million, or $.18 per share, related to TIPRA. The
Corporation is evaluating this new guidance and believes that it may
result in a reduction in income tax expense as a result of a reversal
of a portion of the previously recorded tax-related charge. The amount
and timing of this potential tax reduction is still being evaluated.
