<font style="FONT-FAMILY: Times New Roman" size="2">The preparation
of consolidated financial statements requires management to make
estimates and assumptions in the application of certain of our
accounting policies that materially affect the reported amounts of
assets, liabilities, revenue and expenses. As a result of
unanticipated events or circumstances, actual results could differ
from those estimates. Events occurring subsequent to the date of
our consolidated statement of condition were evaluated for
potential recognition or disclosure in our consolidated financial
statements through February 22, 2010, the date we filed this
Form 10-K with the SEC.</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">The following
is a summary of our significant accounting policies.</font></p>
<p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">Basis of
Presentation:</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">Our
consolidated financial statements include the accounts of the
parent company and its majority- and wholly-owned subsidiaries,
including State Street Bank, as well as the four asset-backed
commercial paper conduits which we consolidated in May 2009 and the
partnership trusts utilized in connection with our tax-exempt
investment program. All material inter-company transactions and
balances have been eliminated. Certain previously reported amounts
have been reclassified to conform to current year
presentation.</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">We consolidate
subsidiaries in which we hold a majority of the voting rights or
exercise control. Investments in unconsolidated subsidiaries,
recorded in other assets, are generally accounted for using the
equity method of accounting if we have the ability to exercise
significant influence over the operations of the investee. For
investments accounted for under the equity method, our share of
income or loss is recorded in processing fees and other revenue in
our consolidated statement of income. Investments not meeting the
criteria for equity method treatment are accounted for using the
cost method of accounting.</font></p>
<p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">Foreign Currency
Translation:</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">The assets and
liabilities of our operations with functional currencies other than
the U.S. dollar are translated at month-end exchange rates, and
revenue and expenses are translated at rates that approximate
average monthly exchange rates. Gains or losses from the
translation of the net assets of subsidiaries with functional
currencies other than the U.S. dollar, net of related taxes, are
recorded in accumulated other comprehensive income, a component of
shareholders’ equity in our consolidated statement of
condition.</font></p>

Equivalents:</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">For purposes of
the consolidated statement of cash flows, we have defined cash and
cash equivalents as cash and due from banks.</font></p>
<p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">Securities Purchased Under
Resale Agreements and Securities Sold Under Repurchase
Agreements:</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">U.S. Treasury
and federal agency securities, referred to as “U.S.
government securities,” purchased under resale agreements or
sold under repurchase agreements are treated as collateralized
financing transactions, and are recorded in our consolidated
statement of condition at the amounts at which the securities will
be subsequently resold or repurchased, plus accrued interest. Our
policy is to take possession or control of securities underlying
resale agreements, allowing borrowers the right of collateral
substitution and/or short-notice termination. We revalue these
securities daily to determine if additional collateral is necessary
from the borrower to protect us against credit exposure. We can use
these securities as collateral for repurchase agreements. For
securities sold under repurchase agreements collateralized by our
U.S. government securities portfolio, the dollar value of the U.S.
government securities remains in investment securities in our
consolidated statement of condition. Where a master netting
agreement exists or both parties are members of a common clearing
organization, resale and repurchase agreements with the same
counterparty or clearing house and maturity date are reported on a
net basis.</font></p>
<p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">Investment
Securities:</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">Investment
securities held by us are classified as either trading account
assets, investment securities available for sale or investment
securities held to maturity at the time of purchase, based on
management’s intentions.</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">Trading account
assets are debt and equity securities purchased in connection with
our trading activities and, as such, are expected to be sold in the
near term. Our trading activities typically involve active and
frequent buying and selling with the objective of generating
profits on short-term movements. Securities available for sale are
those that we intend to hold for an indefinite period of time.
Available-for-sale securities include securities utilized as part
of our asset and liability management activities that may be sold
in response to changes in interest rates, pre-payment risk,
liquidity needs or other similar factors. Securities held to
maturity are debt securities that management has the intent and the
ability to hold to maturity.</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">Trading account
assets are carried at fair value. Both realized and unrealized
gains and losses on trading account assets are recorded in trading
services revenue in our consolidated statement of income. Debt and
marketable equity securities classified as available for sale are
carried at fair value, and after-tax net unrealized gains and
losses are recorded in accumulated other comprehensive income.
Gains or losses realized on sales of available-for-sale securities
are computed using the specific identification method and are
recorded in gains (losses) related to investment securities, net,
in our consolidated statement of income. Securities held to
maturity are carried at cost, adjusted for amortization of premiums
and accretion of discounts.</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">Management
reviews the fair values of investment securities at least
quarterly, and evaluates individual securities for impairment that
may be deemed to be other than temporary. For impaired securities
that we plan to sell, or when it is more likely than not that we
will be forced to sell, the security, the impairment is deemed to
be other than temporary. Otherwise, management determines whether
or not it expects to recover the entire amortized cost basis of the
security, primarily by comparing the present value of expected
future principal, interest and other contractual cash flows to the
amortized cost basis. When management concludes that
other-than-temporary impairment exists, the impairment is separated
into the amount related to credit losses and the amount related to
factors other than credit. The amount related to credit losses is
recognized in our consolidated statement of income in gains
(losses) related to investment securities, net, and the amortized
cost basis of the security is written down by this amount. The
portion of impairment related to all other factors is recognized in
other comprehensive income.</font></p>
<p style="MARGIN-TOP: 0px; MARGIN-BOTTOM: 0px"><font size="1"> </font></p>
<p style="MARGIN-TOP: 0px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">Interest
revenue for debt securities is recognized in our consolidated
statement of income using the interest method, or on a basis
approximating a level rate of return over the contractual or
estimated life of the security. The level rate of return considers
any nonrefundable fees or costs, as well as purchase premiums or
discounts, resulting in amortization or accretion
accordingly.</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">With respect to
debt securities acquired, for those which management considers it
probable as of the date of acquisition that we will be unable to
collect all contractually required principal, interest and other
payments, the excess of management’s estimate of undiscounted
future cash flows from these securities over their initial recorded
investment is accreted into interest revenue on a level-yield basis
over the securities’ estimated remaining terms. Subsequent
decreases in these securities’ expected future cash flows are
either recognized prospectively through an adjustment of the yields
on the securities over their remaining terms, or are evaluated for
other-than-temporary impairment as described above. Increases in
expected future cash flows are recognized prospectively over the
securities’ estimated remaining terms through the
recalculation of their yields.</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">With respect to
debt securities acquired which are considered to be beneficial
interests in securitized financial assets, for certain of these
beneficial interests, the excess of management’s estimate of
undiscounted future cash flows from these securities over their
initial recorded investment is accreted into interest revenue on a
level-yield basis over the securities’ estimated remaining
terms. Subsequent decreases in these securities’ expected
future cash flows are either recognized prospectively through an
adjustment of the yields on the securities over their remaining
terms, or are evaluated for other-than-temporary impairment as
described above. Increases in expected future cash flows are
recognized prospectively over the securities’ estimated
remaining terms through the recalculation of their
yields.</font></p>
<p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">Loans and Lease
Financing:</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">Loans generally
are recorded at their principal amount outstanding, net of the
allowance for loan losses, unearned income, and any net unamortized
deferred loan origination fees. Acquired loans are recorded at fair
value, based on management’s expectation with respect to
future principal and interest collection as of the date of
acquisition. The carrying amount of acquired loans is evaluated
periodically using a discounted cash flow model, which incorporates
management expectations of future principal and interest
collection. The impact of any changes in expectations is recognized
in our consolidated results of operations through either a
provision for loan losses or an adjustment to the yield of the
loans.</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">Loans acquired
with evidence of deterioration in credit quality subsequent to
origination, and for which it is probable on the date of
acquisition that we will be unable to collect all contractually
required payments, are recorded at the lower of cost or fair value.
The excess of expected future cash flows from these loans over
their initial recorded investment is accreted into interest revenue
on a level yield basis over the remaining life of the loans. The
carrying amount of acquired loans is assessed on an ongoing basis
using a discounted cash flow model, which incorporates management
expectations of prepayments. Subsequent decreases in expected cash
flows result in an increase to the related valuation allowance to
allow the loan to maintain its level yield. Increases in expected
cash flows are recognized, first, as a reduction of any remaining
valuation allowance, and then recognized prospectively over the
remaining life of the loan through a recalculation of the
loan’s level yield.</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">Interest
revenue for loans is recognized in our consolidated statement of
income using the interest method or on a basis approximating a
level rate of return over the term of the loan. Fees received for
providing loan commitments and letters of credit that we anticipate
will result in loans typically are deferred and amortized to
interest revenue over the life of the related loan, beginning with
the initial borrowing. Fees on commitments and letters of credit
are amortized to processing fees and other revenue over the
commitment period when funding is not known or expected.</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">Loans are
placed on non-accrual status when they become 60 days past-due
as to either principal or interest, or earlier when full collection
of principal or interest is not considered probable. Loans
60 days past-due, but considered both well secured and in the
process of collection, are treated as exceptions and may be
excluded from non-accrual status. When we place a loan on
non-accrual status, the accrual of interest is discontinued and
previously recorded but unpaid interest is reversed and generally
charged against interest revenue. For loans on non-accrual status,
revenue is recognized on a cash basis after recovery of principal,
if and when interest payments are received.</font></p>
<p style="MARGIN-TOP: 0px; MARGIN-BOTTOM: 0px"><font size="1"> </font></p>
<p style="MARGIN-TOP: 0px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">Leveraged lease
investments are reported at the aggregate of lease payments
receivable and estimated residual values, net of non-recourse debt
and unearned income. Lease residual values are reviewed regularly
for other-than-temporary impairment, with valuation adjustments
recorded currently against processing fees and other revenue.
Unearned income is recognized to yield a level rate of return on
the net investment in the leases. Gains and losses on residual
values of leased equipment sold are recorded in processing fees and
other revenue.</font></p>
<p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">Allowance for Loan
Losses:</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">The adequacy of
the allowance for loan losses, recorded in our consolidated
statement of condition, is evaluated on a regular basis by
management. Factors considered in evaluating the adequacy of the
allowance include previous loss experience, current economic
conditions and adverse situations that may affect the
borrower’s ability to repay, the estimated value of the
underlying collateral, if any, and the performance of individual
credits in relation to contract terms, and other relevant factors.
The provision for loan losses, recorded in our consolidated
statement of income, is based upon management’s estimate of
the amount necessary to maintain the allowance at a level adequate
to absorb estimated probable credit losses.</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">Loans are
charged off to the allowance for loan losses in the reporting
period in which either an event occurs that confirms the existence
of a loss or a loan or a portion of a loan is determined to be
uncollectible. Recoveries are recorded as additions to the
allowance on a cash basis.</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">In addition, we
maintain a reserve for off-balance sheet credit exposures that is
recorded in other liabilities in our consolidated statement of
condition. The adequacy of this reserve is subject to the same
considerations and review as the allowance for loan losses.
Provisions to change the level of this reserve are recorded in
other expenses in our consolidated statement of income.</font></p>
<p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">Premises and
Equipment:</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">Buildings,
leasehold improvements, computers, software and other equipment are
carried at cost less accumulated depreciation and amortization.
Depreciation and amortization, recorded in occupancy expense and
information systems and communications expense in our consolidated
statement of income, are computed using the straight-line method
over the estimated useful lives of the related assets or the
remaining terms of the leases, generally 3 to 40 years.
Maintenance and repairs are charged to expense as incurred, while
major leasehold improvements are capitalized and expensed over
their estimated useful lives or terms of the lease. For premises
held under leases for which we have an obligation to restore the
facilities to their original condition upon expiration of the
lease, we expense the anticipated related costs over the term of
the lease.</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">Costs related
to internal-use software development projects that provide
significant new functionality are capitalized. We consider projects
for capitalization that are expected to yield long-term operational
benefits, such as applications that result in operational
efficiencies and/or incremental revenue streams. Software
customization costs relating to specific customer enhancements are
expensed as incurred.</font></p>
<p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">Goodwill and Other
Intangible Assets:</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">Goodwill
represents the excess of the cost of an acquisition over the fair
value of the net tangible and other intangible assets acquired.
Other intangible assets represent purchased assets that can be
distinguished from goodwill because of contractual rights or
because the asset can be exchanged on its own or in combination
with a related contract, asset or liability. Goodwill is not
amortized, but is subject to annual evaluation for impairment.
Other intangible assets related to customer relationships generally
are amortized on a straight-line basis over periods ranging from
twelve to twenty years, and core deposit intangible assets over
twenty-two years, with amortization recorded in other expenses.
Impairment of goodwill is deemed to exist if the carrying value of
a reporting unit, including its allocation of goodwill and other
intangible assets, exceeds its estimated fair value. Impairment of
other intangible assets is deemed to exist if the balance of the
other intangible asset exceeds the cumulative expected net cash
inflows related to the asset over its remaining estimated useful
life. If these reviews determine that goodwill or other intangible
assets are impaired, the value of the goodwill or the other
intangible asset is written down through a charge to other
expenses.</font></p>

Revenue:</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">Fees from
investment servicing, investment management, securities finance,
trading services and certain types of processing fees and other
revenue are recorded in our consolidated statement of income based
on estimates or specific contractual terms as transactions occur or
services are rendered, provided that persuasive evidence exists,
the price to the customer is fixed or determinable and
collectability is reasonably assured. Amounts accrued at period-end
are recorded in accrued income receivable in our consolidated
statement of condition. Performance fees from investment management
are recorded when earned, based on predetermined benchmarks
associated with the applicable fund’s performance.</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">Interest
revenue on interest-earning assets and interest expense on
interest-bearing liabilities are recorded in our consolidated
statement of income and are generally based on the effective yield
of the related financial asset or liability.</font></p>
<p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">Employee Benefits
Expense:</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">Employee
benefits expense, recorded in our consolidated statement of income,
includes costs of certain pension and other post-retirement benefit
plans related to prior and current service, which are accrued on a
current basis, as well as contributions associated with defined
contribution savings plans, unrestricted cash and stock awards
under other employee incentive compensation plans, and the
amortization of restricted stock awards.</font></p>
<p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">Equity-Based
Compensation:</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">We record
compensation expense equal to the estimated fair value on the grant
date of common stock options granted to employees in our
consolidated statement of income, on a straight-line basis over the
options’ vesting period. We record compensation expense for
equity-based awards other than stock options based on the timing of
vesting.</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">We use a
Black-Scholes option pricing model to determine the fair value of
the options granted. The fair values of equity-based awards other
than options, such as restricted stock and deferred stock, are
based on the price of our common stock on the date of grant,
adjusted if appropriate based upon the award’s eligibility to
receive dividends. The option pricing model utilizes
weighted-average assumptions regarding the period of time that
options granted are expected to be outstanding. This model is based
primarily on the historical exercise behavior attributable to
previous option grants, the estimated yield from dividends paid on
our common stock over the expected term of the options, the
expected volatility of the price of our common stock over a period
equal to the expected term of the options, and a risk-free interest
rate based on the U.S. Treasury yield curve at the time of grant
for a period equal to the expected term of the options
granted.</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">Compensation
expense for equity-based awards with terms that provide for a
graded vesting schedule, for which portions of the award vest in
increments over the required service period, is recognized on a
straight-line basis over the required service period for the entire
award. The expense is adjusted for assumptions with respect to the
estimated amount of awards that will be forfeited prior to vesting,
and for employees who have met certain retirement eligibility
criteria. Dividend equivalents for certain equity-based awards are
paid on stock units on a current basis prior to vesting and
distribution.</font></p>
<p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">Income Taxes:</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">We use an asset
and liability approach to account for income taxes. Our objective
is to recognize the amount of taxes payable or refundable for the
current year through charges or credits to the current tax
provision, and to recognize deferred tax assets and liabilities for
the future tax consequences resulting from temporary differences
between the amounts reported in our consolidated financial
statements and their respective tax bases. The measurement of tax
assets and liabilities is based on enacted tax laws and applicable
tax rates. The effects of a tax position on our consolidated
financial statements are recognized when we believe it more likely
than not that the position will be sustained. A deferred tax
valuation allowance is established if it is considered more likely
than not that all or a portion of the deferred tax assets will not
be realized.</font></p>

Share:</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">Basic earnings
per share is calculated pursuant to the “two-class”
method, using net income available to common shareholders and the
weighted-average number of common shares outstanding during the
period, including participating securities. Participating
securities are composed of unvested restricted stock and director
stock awards, which are unvested equity-based awards that contain
non-forfeitable rights to dividends, and are considered to
participate with common shareholders in undistributed earnings.
Diluted earnings per share is calculated by dividing net income
available to common shareholders by the weighted-average number of
common shares outstanding for the period and the shares
representing the dilutive effect of stock options and awards and
other equity-related financial instruments. The effect of stock
options and restricted stock outstanding is excluded from the
calculation of diluted earnings per share in periods in which their
effect would be antidilutive.</font></p>

recurring basis. These financial assets and liabilities are
composed of trading account assets, investment securities available
for sale and various types of derivative financial instruments. In
addition, we measure certain assets, such as goodwill and other
long-lived assets, at fair value on a non-recurring basis to
evaluate those assets for potential impairment. Fair value is
defined as the price that would be received to sell an asset or
paid to transfer a liability in an orderly transaction between
market participants at the measurement date.</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">We categorize
our financial assets and liabilities into the following fair value
hierarchy:</font></p>
<p style="MARGIN-TOP: 6px; MARGIN-BOTTOM: 0px; MARGIN-LEFT: 4%">
<font style="FONT-FAMILY: Times New Roman" size="2">Level 1 –
Financial assets and liabilities with values based on unadjusted
quoted prices for identical assets or liabilities in an active
market. Examples of level 1 financial instruments include
active exchange-traded equity securities and certain U.S.
government securities.</font></p>
<p style="MARGIN-TOP: 6px; MARGIN-BOTTOM: 0px; MARGIN-LEFT: 4%">
<font style="FONT-FAMILY: Times New Roman" size="2">Level 2 –
Financial assets and liabilities with values based on quoted prices
for similar assets and liabilities in active markets, and inputs
that are observable for the asset or liability, either directly or
indirectly, for substantially the full term of the asset or
liability. Examples of level 2 financial instruments include
various types of fixed-income investment securities and
interest-rate and foreign exchange derivative instruments. Pricing
models are utilized to estimate fair value for certain financial
assets and liabilities categorized in level 2.</font></p>
<p style="MARGIN-TOP: 6px; MARGIN-BOTTOM: 0px; MARGIN-LEFT: 4%">
<font style="FONT-FAMILY: Times New Roman" size="2">Level 3 –
Financial assets and liabilities with values based on prices or
valuation techniques that require inputs that are both unobservable
in the market and significant to the overall fair value
measurement. These inputs reflect management’s judgment about
the assumptions that a market participant would use in pricing the
asset or liability, and are based on the best available
information, some of which is internally developed. Examples of
level 3 financial instruments include asset- and mortgage-backed
securities and certain derivative instruments with little or no
market activity and a resulting lack of price
transparency.</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">When
determining the fair value measurements for financial assets and
liabilities carried at fair value on a recurring basis, we consider
the principal or most advantageous market in which we would
transact and consider assumptions that market participants would
use when pricing the asset or liability. When possible, we look to
active and observable markets to price identical assets or
liabilities. When identical assets and liabilities are not traded
in active markets, we look to market observable data for similar
assets and liabilities. Nevertheless, certain assets and
liabilities are not actively traded in observable markets, and we
use alternative valuation techniques to derive fair value
measurements.</font></p>

Entities:</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">We are involved
with various types of special purpose entities, or SPEs, in the
normal course of our business.</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">We use trusts
to structure and sell certificated interests in pools of tax-exempt
investment-grade assets principally to our mutual fund customers.
These trusts are recorded in our consolidated financial statements.
We transfer assets to these trusts, which are legally isolated from
us, from our investment securities portfolio at book value. The
trusts finance the acquisition of these assets by selling
certificated interests issued by the trusts to third-party
investors. The investment securities of the trusts are carried in
investment securities available for sale at fair value. The
certificated interests are carried in other short-term borrowings
in our consolidated statement of financial condition at the amount
owed to the third-party investors. The interest revenue and
interest expense generated by the investments and certificated
interests, respectively, are recorded in net interest revenue when
earned or incurred.</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">We use conduits
in connection with an asset-backed commercial paper program that
provides short-term investments for our customers. The conduits,
which are administered by us, are third-party owned and are
structured as bankruptcy-remote limited liability companies. The
conduits purchase financial assets with various asset
classifications from a variety of independent third parties and
fund those purchases through our customer deposit base, the
issuance of commercial paper to independent third parties or other
short-term sources of liquidity. We do not sell our own assets to
these conduits, and we hold no direct or indirect ownership
interest in them. These conduits meet the definition of a variable
interest entity, or VIE, as defined by existing accounting
standards. We have determined that we are the primary beneficiary
of the conduits, as defined by existing accounting standards, and
the conduits are recorded in our consolidated financial
statements.</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">We manage the
collateral in certain third-party investment vehicles, referred to
as CDOs, which structure and sell debt and equity securities to
investors. These CDOs purchase a portfolio of diversified assets
and fund these asset purchases through the issuance of several
tranches of debt and equity, the repayment and return of which are
linked to the performance of the assets in the CDO. Typically, our
involvement is only as collateral manager. We may also invest in a
small percentage of the debt issued by the CDO. These CDOs
typically meet the definition of a VIE. We have determined that we
are not the primary beneficiary of these CDOs, and do not record
them in our consolidated financial statements. We receive fees for
asset management services provided to the CDOs, which are based on
market price and are recorded in processing fees and other revenue
when earned.</font></p>

Instruments:</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">A derivative
financial instrument is a financial instrument or other contract
which has one or more referenced indices and one or more notional
amounts, either no initial net investment or a smaller initial net
investment than would be expected for similar types of contracts,
and which requires or permits net settlement. Derivatives that we
enter into include forwards, futures, swaps, options and other
instruments with similar characteristics.</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">We record
derivatives in our consolidated statement of condition at their
fair value. On the date a derivative contract is entered into, we
designate the derivative as: (1) a hedge of the fair value of
a recognized fixed-rate asset or liability or of an unrecognized
firm commitment (a “fair value” hedge); (2) a
hedge of a forecasted transaction or of the variability of cash
flows to be received or paid related to a recognized variable-rate
asset or liability (a “cash flow” hedge); (3) a
foreign currency fair value or cash flow hedge (a “foreign
currency” hedge); (4) a hedge of a net investment in a
non-U.S. operation; or (5) held for trading purposes
(“trading” instruments).</font></p>

<font style="FONT-FAMILY: Times New Roman" size="2">Changes in the
fair value of a derivative that is highly effective—and that
is designated and qualifies as a fair value hedge—are
recorded currently in processing fees and other revenue, along with
the changes in fair value of the hedged asset or liability
attributable to the hedged risk. Changes in the fair value of a
derivative that is highly effective—and that is designated
and qualifies as a cash flow hedge—are recorded, net of tax,
in other comprehensive income, until earnings are affected by the
hedged cash flows (<i>e.g.,</i> when periodic settlements on a
variable-rate asset or liability are recorded in earnings). Cash
flow hedge ineffectiveness, defined as the extent to which the
changes in fair value of the derivative exceed the variability of
cash flows of the forecasted transaction, is recorded in processing
fees and other revenue.</font></p>

<font style="FONT-FAMILY: Times New Roman" size="2">Changes in the
fair value of a derivative that is highly effective—and that
is designated and qualifies as a foreign currency hedge—are
recorded currently either in processing fees and other revenue or
in other comprehensive income, net of tax, depending on whether the
hedge transaction meets the criteria for a fair value or a cash
flow hedge. If, however, a derivative is used as a hedge of a net
investment in a non-U.S. operation, its changes in fair value,
to the extent effective as a hedge, are recorded, net of tax, in
the foreign currency translation component of other comprehensive
income. Lastly, entire changes in the fair value of derivatives
classified as trading instruments are recorded in trading services
revenue.</font></p>

<font style="FONT-FAMILY: Times New Roman" size="2">At both the
inception of the hedge and on an ongoing basis, we formally assess
and document the effectiveness of a derivative designated as a
hedge in offsetting changes in the fair value of hedged items and
the likelihood that the derivative will be an effective hedge in
future periods. We discontinue hedge accounting prospectively when
we determine that the derivative is no longer highly effective in
offsetting changes in fair value or cash flows of the underlying
risk being hedged, the derivative expires, terminates or is sold,
or management discontinues the hedge designation.</font></p>

Developments:</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">In June 2009,
the FASB issued a new accounting standard related to accounting for
VIEs. This new standard will amend existing GAAP, will
eliminate the exception for qualifying SPEs, and will modify the
characteristics that identify a VIE. The new standard also provides
new criteria for determining whether an entity is the primary
beneficiary of a VIE, and increases the frequency of required
assessments to determine whether an entity is the primary
beneficiary.</font></p>
<p style="MARGIN-TOP: 6px; TEXT-INDENT: 4%; MARGIN-BOTTOM: 0px">
<font style="FONT-FAMILY: Times New Roman" size="2">The new
standard is effective, for State Street, on January 1, 2010.
Significant State Street and industry efforts are currently
underway to interpret the new standard and its impact. Management
expects, based on current interpretations of the new standard and
proposed additional guidance related to the applicability of the
new standard to collective investment funds, that we will be
required to consolidate additional entities upon adoption,
including certain asset-backed securitization trusts in which we
have investments significant to the trusts and corresponding
unilateral servicer removal rights. Currently, management expects
that adoption will not have a material effect on our consolidated
results of operations or financial condition.</font></p>
