metropolitan area and various subsidiaries including an investment management
company, a leasing company, a Canadian trust company, a New York Edge Act
company and a global fund services provider. Although the operations of other
subsidiaries will be of increasing significance to the Corporation, it is
expected that the Bank will, in the foreseeable future, continue to be the
major source of the Corporation's consolidated assets, revenues and net income.
Northern Trust has not utilized unconsolidated special purpose entities to
provide financing, improve liquidity, transfer assets or manage credit risk.
   Except where the context otherwise requires, all references to "Northern
Trust" refer to Northern Trust Corporation and its subsidiaries on a
consolidated basis.

Critical Accounting Policies
The use of estimates and assumptions is required in the preparation of
financial statements in conformity with generally accepted accounting
principles and actual results could differ from those estimates. The Securities
and Exchange Commission (SEC) has also issued guidance and proposed rules
relating to the disclosure of critical accounting policies. Accounting policies
that are considered critical are those which require management to make
subjective or complex judgments about the effect of matters that are inherently
uncertain and may change in subsequent periods. Changes that may be required in
the underlying assumptions or estimates in these areas could have a material
impact on Northern Trust's future financial condition and results of operations.
   For Northern Trust, accounting policies that are viewed as critical are
those relating to reserving for credit losses, pension plan accounting, and
estimating useful lives of purchased and internally developed software. Because
of their critical nature, management has discussed the development and
selection of each critical accounting estimate with the Audit Committee of the
Board of Directors.

Reserve for Credit Losses. The reserve for credit losses represents
management's estimate of probable inherent losses which have occurred as of the
date of the financial statements. The loan and lease portfolio and other credit
exposures are regularly reviewed to evaluate the adequacy of the reserve
for credit losses. In determining the level of the reserve, Northern Trust
evaluates the reserve necessary for specific nonperforming loans and also
estimates losses inherent in other credit exposures. The result is a reserve
with the following components:
   Specific Reserve. The amount of specific reserves is determined through a
loan-by-loan analysis of nonperforming loans that considers expected future
cash flows, the value of collateral and other factors that may impact the
borrower's ability to pay.
       Allocated Inherent Reserve. The amount of the allocated portion of the
inherent loss reserve is based on loss factors assigned to Northern Trust's
credit exposures based on internal credit ratings. These loss factors are
primarily based on management's judgment of estimated credit losses inherent in
the loan portfolio as well as historical charge-off experience. The Credit
Policy Group determines credit ratings at the time each loan is approved. These
credit ratings are then subject to periodic reviews by the Credit Policy Group,
which is independent of business unit management. Credit Policy makes the final
determination of each loan's rating. Credit ratings range from "1" for the
strongest credits to "9" for the weakest credits; a "9" rated loan would
normally represent a complete loss.
       Unallocated Inherent Reserve. Management determines the unallocated
portion of the inherent loss reserve based on factors that cannot be associated
with a specific credit or loan category. These factors include management's
subjective evaluation of local and national economic and business conditions,
portfolio concentration and changes in the character and size of the loan
portfolio. The unallocated portion of the inherent loss reserve reflects
management's attempt to ensure that the overall reserve appropriately reflects
a margin for the imprecision necessarily inherent in estimates of expected
credit losses.
   Loans, leases and other extensions of credit deemed uncollectible are
charged to the reserve. Subsequent recoveries, if any, are credited to the
reserve. The related provision for credit losses, which is charged to income,
is the amount necessary to adjust the reserve to the level determined through
the above process. Actual losses may vary from current estimates and the amount
of the provision may be either greater than or less than actual net charge-offs.
   The control process maintained by Credit Policy and the lending staff, and
the quarterly analysis of specific and inherent loss components are the
principal methods relied upon by management to ensure that changes in estimated
credit loss levels are adjusted on a timely basis. In addition to Northern
Trust's own experience, management also considers the experience of peer
institutions and regulatory guidance.
   Management's estimates utilized in establishing an adequate reserve for
credit losses are not dependent on any single assumption. Management evaluates
numerous variables, many of which are interrelated or dependent on other
assumptions and estimates, in determining reserve adequacy. Due to the inherent
imprecision in accounting estimates, other

Management's Discussion and Analysis of

estimates or assumptions could reasonably have been used in the current period
and changes in estimates are reasonably likely to occur from period to period.
However, management believes that the established reserve for credit losses
appropriately addresses these uncertainties and is adequate to cover probable
inherent losses which have occurred as of the date of the financial statements.

Pension Plan Accounting. As summarized in Note 19 to the consolidated financial
statements, Northern Trust maintains a noncontributory defined benefit pension
plan covering substantially all employees. Measuring cost and reporting
liabilities resulting from defined benefit pension plans requires the use of
several assumptions regarding future interest rates, asset returns,
compensation increases and other actuarial-based projections relating to the
plan. Due to the long-term nature of this obligation and the assumptions that
are required to be made, the estimates used to determine the periodic pension
expense and the projected pension obligation are closely monitored and adjusted
annually. Under generally accepted accounting principles differences between
these estimates and actual experience are required to be amortized over the
future working lifetime of eligible participants. As a result, these
differences are not recognized as they occur but are recognized systematically
and gradually over subsequent periods.
   Northern Trust recognizes the significant impact that these pension-related
estimates have on the determination of the pension obligations and related
expense and has established procedures for monitoring and setting these
estimates each year. These procedures include an annual review of actual
demographic and investment experience with the pension plan's actuaries. In
addition to actual experience, adjustments to these estimates consider
published interest rate indices, known compensation trends and policies and
economic conditions that may impact the estimated long-term rate of return on
plan assets.
   In determining the pension expense in 2002, Northern Trust utilized a
discount rate of 7.50% for the Qualified Plan and 6.00% for the Nonqualified
Plan. The rate of increase in the compensation level is based on a sliding
scale that averaged 5%. The expected long-term rate of return on Qualified Plan
assets was 9%. In order to provide an understanding of the sensitivity of these
assumptions on the periodic pension expense and projected benefit obligation,
the following table is presented to show the effect of increasing or decreasing
each of these assumptions by 25 basis points.

             Compensation Level Change.............    5.1     (4.9)


In revising these estimates at Northern Trust's September 30, 2002 measurement
date, the following events were considered:
   Discount Rate: Northern Trust utilizes the Moody's AA Corporate Bond rate in
establishing the discount rate for the Qualified Plan. Since this benchmark
rate fell approximately 75 basis points, Northern Trust lowered the discount
rate for the Qualified Plan by a like amount. The discount rate for the
Nonqualified Plan was reduced based on the decline in long-term Treasury bond
rates.
   Compensation Level: In recognition of Northern Trust's initiatives to manage
operating costs, salary increases and incentive programs have been curtailed.
In recognition of these policy changes the compensation scale assumption has
been modified for a three-year period. The compensation policy change, together
with lower inflation rates, resulted in a 140 basis point reduction in this
assumption.
   Rate of Return on Plan Assets: The expected return on plan assets is based
on an estimate of the long-term rate of return on plan assets. Accounting
guidance requires this assumption be reviewed every three to five years. In
2002, Northern Trust's Employee Benefit Committee completed an in-depth Pension
Asset and Liability Modeling study. Based on the asset allocation recommended,
the weighted average expected return for each asset class was determined, which
resulted in a recommendation to lower the expected rate of return by 25 basis
points to 8.75%.
   As a result of these changes in estimates and other actuarial experiences of
the Qualified and Nonqualified plans, the estimated pension expense is expected
to increase by approximately $10.0 million in 2003.

Purchased and Internally Developed Software. A significant portion of Northern
Trust's products and services are depen-dent on complex and sophisticated
computer systems based primarily on purchased and internally developed software
programs. Under Northern Trust's accounting policy, purchased

Management's Discussion and Analysis of
Financial Condition and Results of Operations

software and other allowable internal costs, including compensation, relating
to software developed for internal use are capitalized. Capitalized software is
then amortized over its estimated useful life ranging from 3 to 10 years. At
December 31, 2002, capitalized software totaled $371.1 million and software
amortization in 2002 totaled $75.0 million. Northern Trust believes that the
accounting estimate relating to the determination and ongoing review of the
estimated useful lives of capitalized software is a critical accounting policy.
Northern Trust has this view because rapidly changing technology can
unexpectedly change software functionality, resulting in a significant change
in the useful life, including a complete write-off of software applications.
In addition, product changes can also render existing software as obsolete
requiring a write-off of the carrying value of the asset.
   In order to address this risk, Northern Trust's accounting procedures
require at least an annual review of all software applications to confirm the
reasonableness of asset book values and remaining useful lives. Any adjustments
that may result from this process are reviewed by senior management.

Results of Operations
Overview. Net income for 2002 totaled $447.1 million, down 8% from $487.5
million earned in 2001, which compared with $485.1 million earned in 2000.
Diluted net income per common share decreased 7% to $1.97 from $2.11 in 2001,
which was up 1% from $2.08 in 2000. The net income performance produced a
return on average common stockholders' equity of 16.20% compared with 19.34% in
2001 and 22.09% in 2000. The return on average assets was 1.19% in 2002
compared with 1.37% in 2001 and 1.42% in 2000.
   Earnings for the year were adversely affected by continued weak economic
conditions and equity markets that declined for the third consecutive year.
Although net interest income and treasury management fees increased to record
levels, trust fees, which includes securities lending, foreign exchange trading
profits and other noninterest income declined relative to the prior year.
Despite much steeper declines in worldwide equity markets, as evidenced by the
23% yearly decline in the S&P 500 equity index and 32% fall in the Nasdaq
Composite Index in 2002, trust assets under administration of $1.50 trillion at
December 31, 2002 declined only 10% from the prior year- end. In this difficult
environment revenues declined 3% while operating expenses increased by 2%,
resulting in a 153% productivity ratio.
   Stockholders' equity grew to $3.00 billion, as compared with $2.77 billion
at December 31, 2001 and $2.46 billion at December 31, 2000, primarily through
the retention of earnings, offset in part by the repurchase of common stock
pursuant to the Corporation's share buyback program.
   The Board of Directors maintained the quarterly dividend per common share at
$.17 for an annual rate of $.68. The Board's action reflects a policy of
establishing the dividend rate commensurate with profitability while retaining
sufficient earnings to allow for strategic expansion and the maintenance of a
strong balance sheet and capital ratios.
   Northern Trust's strategy will continue to focus on growing its two
principal business units: Corporate and Institutional Services (C&IS) and
Personal Financial Services (PFS). C&IS provides investment asset
administration and related services to corporate and public entity retirement
funds, foundation and endowment clients, fund managers, insurance companies and
government funds; a comprehensive array of retirement consulting, actuarial and
recordkeeping services; and a full range of commercial banking services,
including treasury management services. PFS provides financial services to
individuals and small/mid-size businesses through a unique office network in
twelve states. An important element in this strategy is increasing the
penetration of the C&IS and PFS target markets with investment management and
related services and products provided by a third business unit, Northern Trust
Global Investments (NTGI). In executing this strategy, Northern Trust
emphasizes service quality through a high level of personal service
complemented by the effective use of technology. Operating support for these
business units is provided through the Worldwide Operations and Technology
business unit (WWOT). Northern Trust closely monitors expense growth and
capital expenditures to ensure that short- and long-term business strategies
and performance objectives are effectively balanced.

Noninterest Income. Noninterest income represented 70% of total taxable
equivalent revenue in 2002 compared with 71% in both 2001 and 2000. Noninterest
income totaled $1.54 billion in 2002, $1.61 billion in 2001, and $1.57 billion
in 2000.
   Trust Fees. Trust fees accounted for 80% of total noninterest income and 56%
of total taxable equivalent revenue in 2002. Trust fees for 2002 decreased 2%
to $1.23 billion from $1.26 billion in 2001, which was up 3% from $1.23 billion
in 2000. Over the past five years, trust fees have increased at a compound
growth rate of 12%. Total trust assets under administration at December 31,
2002 were $1.50 trillion, down 10% from $1.67 trillion a year ago, including
$472.0 billion of global custody assets. Trust assets under administration
included managed assets of $302.5 billion, down from $319.9 billion at the end
of 2001. Previously reported total and managed assets have been adjusted to
eliminate a duplicate calculation. This adjustment had no impact on trust
revenues.
   Trust fees are based on the market value of assets managed and administered,
the volume of transactions, secu-

rities lending volume and spreads, and fees for other services rendered.
Asset-based fees are typically determined on a sliding scale so that as the
value of a client portfolio grows in size, Northern Trust receives a smaller
percentage of the increasing value as fee income. Therefore, market value or
other changes in a portfolio's size do not typically have a proportionate
impact on the level of trust fees. Certain investment management fee
arrangements also may provide for performance fees, which are based on client
portfolio returns exceeding predetermined levels. In addition, C&IS trust
relationships are increasingly priced to reflect earnings from activities such
as custody-related deposits and foreign exchange trading that are not included
in trust fees. Custody-related deposits maintained with bank subsidiaries and
foreign branches are primarily interest-bearing and averaged $9.8 billion in
2002, $9.3 billion in 2001 and $7.6 billion in 2000.
   A discussion of the trust-related services provided by C&IS, PFS and NTGI
follows. The operating results, which include both trust and banking services,
for C&IS and PFS are provided on pages 40-44.
   Corporate and Institutional Services. Trust fees in C&IS decreased 2% in
2002 to $626.5 million from $642.4 million in 2001, which was up 5% from $613.3
million in 2000. These fees are derived from the full set of investment asset
administration and related services that Northern Trust provides worldwide to
corporate and public entity retirement funds, foundation and endowment clients,
fund managers, insurance companies and government funds. Northern Trust's
investment asset administration and related services include worldwide master
trust and master custody, settlement and reporting, cash management, and risk
and performance analysis services. Trust custody relationships managed by C&IS
often include investment management, securities lending, transition management
and commission recapture services provided through NTGI. In addition to these
services, Northern Trust offers its C&IS clients a comprehensive array of
retirement consulting, actuarial and recordkeeping services and a full range of
commercial banking services.

   The decline in C&IS trust fees resulted from lower securities lending fees,
which totaled $100.0 million, compared with $135.7 million in 2001. The prior
year results benefited from both higher volumes and increased spreads earned on
the investment of collateral, due to the 11 decreases in the federal funds rate
during the year. Fees from custody services increased 2% as a result of net new
business, offset in part by the impact of lower market values of assets
administered. Retirement services recordkeeping and consulting fees increased
6% to $72.3 million.
   C&IS trust fees benefited from net new asset management business, offset in
large part by the impact of lower market values of assets under management.
Northern Trust continued to broaden its offerings of both passive and actively
managed investment products to trust and banking clients. Fees from investment
products totaled $186.8 million, up slightly from $182.4 million in 2001,
driven primarily by growth in institutional money market funds.

Management's Discussion and Analysis of
Financial Condition and Results of Operations


   Total C&IS trust assets under administration totaled $1.35 trillion at
December 31, 2002, 11% lower than $1.51 trillion at December 31, 2001. Included
in C&IS assets administered are those for which Northern Trust has management
responsibility. Managed assets were invested 24% in equity securities, 16% in
fixed income securities and 60% in cash and other assets. The cash and other
assets that have been deposited by investment firms as collateral for
securities they have borrowed from trust clients are invested by Northern Trust
and are included in trust assets under administration as managed assets. The
collateral totaled $89.0 billion and $92.2 billion at December 31, 2002 and
2001, respectively.
   New recurring C&IS business sold and transitioned net of lost business in
2002, represented approximately $43 million in annualized trust fees, compared
with $71 million in 2001. The lower level of net new business sold primarily
reflects the loss of two large custody clients through the periodic rebidding
process and the loss of several clients due to mergers and acquisitions.
Approximately 45% of the new business sold came from existing clients and 55%
from new relationships.
       Personal Financial Services. Northern Trust has positioned itself in
markets having significant concentrations of wealth and growth potential.
During the year, Northern Trust opened an office in Los Altos, California and
expanded or remodeled several existing offices. Its unique network of Personal
Financial Services offices includes 82 locations in twelve states. PFS also
includes the Wealth Management Group, which provides customized products and
services to meet the complex financial needs of families and individuals in the
United States and throughout the world with assets typically exceeding
$100 million.
       At December 31, 2002 trust assets under administration in PFS totaled
$156.7 billion, compared with $166.8 billion at December 31, 2001. Included in
assets administered are those for which Northern Trust has management
responsibility. Managed assets were invested 41% in equity securities, 41% in
fixed income securities and 18% in cash and other assets.
       PFS trust fees totaled $606.6 million for the year, compared with $616.7
million in 2001 and $614.9 million in 2000. The modest decrease in the current
year resulted from the continued decline in the equity markets, partially
offset by net new business. The Wealth Management Group's trust fees increased
6% to $74.8 million, and at year-end the Wealth Management Group administered
$65.1 billion for significant family asset pools nationwide, up from $64.9
billion last year.
       Net new recurring PFS business sold and transitioned in 2002 totaled
approximately $41 million in annualized trust fees, down from $63 million in
2001. The poor equity market conditions together with weak investor confidence
slowed new business activity during 2002.
       Northern Trust Global Investments. Northern Trust Global Investments
brings together the investment management activities of the C&IS and PFS
businesses. The revenues associated with this business unit are fully allocated
to C&IS and PFS. NTGI integrates Northern Trust's portfolio management,
research and trading with client servicing, institutional sales, marketing and
product management, while continuing to emphasize Northern Trust's overall
relationship orientation.
       Northern Trust Investments, Inc. (NTI), a separate subsidiary of the
Bank and a registered investment advisor, provides investment management
services to Northern Trust's two mutual fund families and institutional
clients. This structure makes the administration of these activities more
efficient as well as accommodates future development of Northern Trust's
investment business.
       NTGI's international relationships include joint ventures, alliances and
distribution arrangements with entities in the United Kingdom, Ireland,
Germany, Japan and the Cayman Islands.
       NTGI's strategic focus on investment management, branding, product
management, distribution and client servicing helped drive Northern Trust's
continued growth in new business. During 2002 Northern Trust continued to
achieve solid investment results across asset classes. For example, 31 of 52
eligible mutual funds advised by Northern Trust were ranked in the top two
quintiles for 2002 investment performance by Lipper Analytical Services.
Similarly, 16 of 38 eligible Northern-managed mutual funds were rated as 4- or
5-star for one-year performance by Morningstar. Also in 2002, NTGI completed
the initial funding of its private equity fund and introduced both an actively
managed hedge fund and an arbitrage fund, its second hedge fund of funds.
       On January 31, 2003, Northern Trust closed its acquisition of the global
passive equity, enhanced equity and passive fixed income investment management
business of Deutsche Bank AG. Under the terms of the agreement, Northern Trust
paid approximately $100 million primarily based on assets under management of
$44.1 billion. This payment takes into consideration certain assets that are
expected to transition during the next several months. Additional payments will
also be made as other assets are transitioned later this year.
       Consolidated securities lending revenues in 2002 stood at $101.0 million
with average loan volume increases of 10% over the past three years. Since its
inception in 1981, there have been no losses to collateral fund participants.
May 2002 saw the successful launch of EquiLend LLC, the open, global,

standards-based securities lending platform founded by Northern Trust and nine
other industry-leading financial institutions. The platform focuses on
standardization and maximizing efficiencies in the global securities lending
industry.
   At year-end, Northern Trust managed $302.5 billion in trust assets for
personal and institutional clients, down a modest 5% from $319.9 billion at
year-end 2001, despite weaker equity markets as evidenced by the 23% yearly
decline in the S&P 500 equity index and the 32% fall in the Nasdaq Composite
Index. Despite the slight decline in 2002, trust assets under management have
grown at a five-year compound annual rate of 9%.
   Foreign Exchange Trading Profits. Foreign exchange trading profits totaled
$106.4 million, 24% below the $139.8 million reported in 2001, which in turn
was 8% lower than the record $152.7 million in 2000. As custodian, Northern
Trust provides foreign exchange services in the normal course of business.
Active management of currency positions, within conservative limits, also
contributes to trading profits. The current year foreign exchange results
reflect lower client volumes and reduced market volatility in the major
currencies. The decline in profits in 2001 reflected reduced market volatility
in the major currencies, offset in part by growth in client volumes.
   Treasury Management Fees. The fee portion of treasury management revenues
totaled $96.3 million in 2002, an increase of 12% from the $86.4 million
reported in 2001 compared with $73.9 million in 2000. Total treasury management
revenues, which, in addition to fees, include the fee equivalent value of
compensating deposit balances, increased 2% to $119.8 million from $117.6
million in 2001 compared with $109.7 million in 2000, reflecting the continued
growth of new business in both paper- and electronic-based products. The
increase in the fee portion of the revenue was partly a result of more clients
paying for services in fees rather than by compensating deposit balances.
   Security Commissions and Trading Income. Security commissions and trading
income totaled $42.9 million in 2002, compared with $35.5 million in 2001 and
$34.3 million in 2000. This income is primarily generated from securities
brokerage services provided by Northern Trust Securities, Inc. (NTSI). The
increase in both years reflects continued growth in securities brokerage
activities, up 21% in 2002 and 5% in 2001.
   Other Operating Income. Other operating income includes loan, letter of
credit and deposit-related service fees and other miscellaneous income from
asset sales. Other operating income in 2002 totaled $57.8 million compared with
$91.7 million in 2001 and $77.9 million in 2000. The current year results have
been reduced by a $15.0 million write-off of an investment in myCFO, Inc., a
$4.8 million write-off of an equity investment in the Global Straight Through
Processing Association and a $4.6 million write-down in the residual value of
an aircraft leased to United Airlines. Partially offsetting these transactions
was approximately $8.5 million in gains by Norlease, Inc. from the sales of
leased equipment at the end of scheduled lease terms. Excluding nonrecurring
items, the remainder of the decrease in other operating income in 2002 is
primarily attributable to lower levels of trust deposit-related revenues due to
lower interest rates, partially offset by higher loan service, standby letter
of credit, and banking-related fees. The prior year included a $9.2 million
nonrecurring gain on the sale of an 80% interest in Northern Trust's lockbox
operations. Nonrecurring gains from the sale of assets in 2000 totaled $4.5
million.
   Investment Security Gains. Net security gains were $.3 million in 2002. This
compares with net gains of zero in 2001 and $.2 million in 2000.

Net Interest Income. Net interest income is defined as the total of interest
income and amortized fees on earning assets, less interest expense on deposits
and borrowed funds, adjusted for the impact of off-balance sheet hedging
activity. Earning assets, which consist of securities, loans and money market
assets, are financed by a large base of interest-bearing funds, including
retail deposits, wholesale deposits, short-term borrowings, senior notes and
long-term debt. Earning assets are also funded by net noninterest-related
funds. Net noninterest-related funds consist of demand deposits, the reserve
for credit losses and stockholders' equity, reduced by nonearning assets
including cash and due from banks, items in process of collection, buildings
and equipment and other nonearning assets. Variations in the level and mix of
earning assets, interest-bearing funds and net noninterest-related funds, and
their relative sensitivity to interest rate movements, are the dominant factors
affecting net interest income. In addition, net interest income is impacted by
the level of nonperforming assets and client use of compensating deposit
balances to pay for services.
   Net interest income for 2002 was a record $601.8 million, up 1% from $595.3
million in 2001, which was up 5% from $568.6 million in 2000. When adjusted to
a fully taxable equivalent (FTE) basis, yields on taxable, nontaxable and
partially taxable assets are comparable, although the adjustment to a FTE basis
has no impact on net income. Net interest income on a FTE basis for 2002 was a
record $650.5 million, an increase of $2.6 million from $647.9 million in 2001
which in turn was up 4% from $621.9 million in 2000. Through steady asset
growth and conservative interest rate risk management, Northern Trust has been
successful in generating year over year improvement in

Management's Discussion and Analysis of

net interest income as evidenced by the fact that 2002 represents the
nineteenth consecutive year of record performance.
The improvement in FTE net interest income in 2002 was driven primarily by a 5%
increase in average earning assets.
   Earning assets averaged $33.6 billion, up 5% from the $32.0 billion reported
in 2001, which was up from $30.7 billion in 2000. The growth in average earning
assets reflects a $3.1 billion increase in money market assets partially offset
by a $1.3 billion decrease in securities and a $.2 billion decrease in loans.
   Loans averaged $17.6 billion compared to $17.8 billion last year. The
decline reflects a lower level of commercial loans, partially offset by an
increase in residential mortgages and lease financing. Residential mortgages
were up $559 million to $7.7 billion on average, and lease financing increased
$114 million. In addition, reflecting growth in lending to Wealth Management
and private banking clients, personal loans increased $99 million or 5% to
average $2.3 billion for the year. Offsetting these increases was a decline of
$715 million or 14% in commercial and industrial loans to average $4.3 billion
for the year. International loans decreased from $708 million on average last
year to $383 million in 2002. The loan portfolio includes noninterest-bearing
domestic and international overnight advances related to processing certain
trust client investments, which averaged $673 million in 2002, down from $872
million a year ago. Securities averaged $7.2 billion in 2002, down 16%
resulting primarily from lower levels of federal agency securities. Money
market assets averaged $8.8 billion in 2002 compared with $5.7 billion in 2001.
   The increase in average earning assets of $1.6 billion was funded through
growth in interest-bearing deposits, other interest-related funds and
noninterest-related funds. The deposit growth was concentrated primarily in
foreign office time deposits, up $1.0 billion resulting from increased global
custody activity, and savings and money market deposits, up $443 million.
Partially offsetting these increases were lower levels of personal and
commercial certificates of deposit and time deposits, down a combined $1.0
billion on average for the year.

   Other interest-related funds averaged $10.0 billion, up $823 million,
principally from higher levels of federal funds purchased and borrowings from
the Federal Home Loan Bank, partially offset by lower levels of treasury
investment program balances and securities sold under agreements to repurchase.
Average net noninterest-related funds increased $308 million, mainly due to
higher noninterest-bearing deposits and stockholders' equity. Stockholders'
equity for the year averaged $2.9 billion, an increase of $246.6 million or 9%
from 2001, principally due to the retention of earnings, offset in part by the
repurchase of common stock pursuant to the Corporation's share buyback program.
   The net interest spread improved to 1.57% in 2002 from 1.38% in 2001
resulting primarily from the favorable im-

pact of the decline in interest rates on average funding costs. While
noninterest-related funds increased $308 million to $5.4 billion, the value of
these funds was diminished by the decline in interest rates as the average
return on earning assets fell by 158 basis points. As a result of the above,
the net interest margin of 1.93% in 2002 was down 9 basis points from the prior
year. For additional analysis of average balances and interest rate changes
affecting net interest income, refer to the Average Statement of Condition with
Analysis of Net Interest Income on pages 92 and 93.

Provision for Credit Losses. The provision for credit losses of $37.5 million
was $29.0 million lower than the $66.5 million required in 2001, which in turn
was $42.5 million greater than the $24.0 million provision in 2000. For a
discussion of the reserve and provision for credit losses, refer to pages 50
through 53.

Noninterest Expenses. Noninterest expenses for 2002 totaled $1.43 billion, up
$22.7 million or 2% from $1.41 billion in 2001, which was up 2% from $1.38
billion in 2000. Expense growth in 2002 as in 2001 continued at moderate
levels, resulting from the ongoing initiatives implemented by management in
2001 to reduce certain discretionary expenses. These initiatives included
closely monitoring staffing levels, limiting staff-related and other
discretionary expenses, and maintaining the change that was made in 2001 to
certain incentive plans to include a stock option grant component in lieu of
cash. This initiative resulted in a $20.4 million expense savings in 2001 when
compared to programs in place prior to this initiative. In addition, the
adoption of new accounting requirements in 2002 to eliminate goodwill
amortization costs reduced expenses by $9.9 million or $8.0 million after-tax.
   The productivity ratio, defined as total revenue on a taxable equivalent
basis divided by noninterest expenses, was 153% for 2002, 160% in 2001 and 158%
in 2000.
   Compensation and Benefits. Compensation and benefits, which represent 56% of
total noninterest expenses, decreased 1% to $797.1 million in 2002 from $808.0
million in 2001, which was up 1% from $798.4 million in 2000. Compensation
costs, the largest component of noninterest expenses, totaled $666.3 million,
down $19.5 million from $685.8 million a year ago. The impact of outsourcing
lockbox services in the third quarter of 2001 and lower performance-based pay
offset salary increases and higher benefit costs. Performance-based
compensation expense for 2002 decreased $23.8 million from 2001, which in turn
had decreased $50.0 million from 2000. Compensation levels in both 2002 and
2001 reflect the impact of slower revenue growth, lower investment portfolio
performance, corporate earnings performance and modifications made to certain
cash incentive plans. Staff on a full-time equivalent basis averaged 9,371 in
2002, down 1% compared with 9,484 in 2001, which was up 5% from 9,019 in 2000.
The decline in average staffing levels during 2002 reflects the third quarter
2001 outsourcing of lockbox operations and the close monitoring of staff
levels. The increase in staff levels during 2001 was required to support growth
initiatives and strong new business in both C&IS and PFS. Average staff levels
in 2001 would have been higher by approximately 190 posts and compensation
expense would have increased more, had Northern Trust not outsourced its
lockbox services during 2001. These expenses are now included in outside
services purchased and reflected in other operating expenses. Staff on a
full-time equivalent basis totaled 9,317 at December 31, 2002, a decline of 136
positions or 1% since the end of 2001.
   Employee benefit costs for 2002 totaled $130.8 million, up $8.6 million or
7% from $122.2 million in 2001, which was 12% higher than the $109.3 million in
2000. The increase in employee benefits in each of the past two years primarily
reflects higher payroll taxes, medical and dental plan costs, and retirement
plan benefits, which included higher benefits associated with revisions made to
the ESOP.
   Occupancy Expense. Net occupancy expense totaled $106.5 million, up 6% or
$6.3 million from $100.2 million in 2001, which was up 15% from $87.3 million
in 2000. The principal components of the 2002 occupancy expense increase were
higher rent and the expansion and renovation of existing offices, including the
relocation of London Branch staff to a new facility in the Canary Wharf
district, one of Europe's largest financial centers. These increases were
partially offset by lower real estate taxes and utility costs. The increase in
2001 resulted from higher rental and utility costs, depreciation and
maintenance of buildings and leasehold improvements.
   Equipment Expense. Equipment expense, which includes depreciation, rental
and maintenance costs, totaled $89.0 million, up 4% from $85.7 million in 2001,
which was 17% higher than the $73.1 million in 2000. The 2002 results reflect
higher levels of depreciation and maintenance of computer hardware and data
line lease costs, partly offset by lower costs for equipment maintenance and
depreciation of personal computers. The 2001 results reflect higher levels of
computer hardware depreciation expense, data line lease costs, rental and
maintenance costs of computers and equipment.
   Other Operating Expenses. Other operating expenses for 2002 totaled $439.5
million, up 6% from $415.5 million in 2001, which was down 2% from $422.9
million in

2000. The higher expense level for 2002 was due in part to higher costs
associated with professional services, processing errors incurred in servicing
and managing financial assets and performing banking activities, software
amortization and other expenditures to support business growth. Higher
professional services include increased costs associated with payments made for
receivables management and lockbox services. Partially offsetting these
increases was the adoption of new accounting requirements in 2002 to eliminate
goodwill amortization costs, which reduced expenses by $9.9 million or $8.0
million after-tax.
   The decline in the 2001 expense level reflects the net impact of several
factors. These included expense reductions as a result of a decrease in
performance-based fees paid to investment sub-advisors, lower levels of
business development costs, and a reduction in charges associated with
processing errors incurred in servicing and managing financial assets and
performing banking activities. These lower expenses were partially offset by
higher costs associated with software amortization, expansion of the personal
trust and banking office network, and other expenditures to support business
growth. Other operating expense in 2001 also included $9.4 million in payments
made related to outsourcing receivables management and lockbox services in the
second half of the year. Before these services were outsourced, the majority of
these costs were included in salary and benefit expense.

Provision for Income Taxes. The provision for income taxes was $221.9 million
in 2002 compared with $244.4 million in 2001 and $245.0 million in 2000. The
current year reflects a lower federal and state income tax provision resulting
primarily from the reduction in pre-tax earnings for the year. The effective
tax rate was 33% for both 2002 and 2001, compared with 34% for 2000.

Business Segments
Northern Trust Corporation, under Chairman, Chief Executive Officer and
President William A. Osborn, organizes around two principal client-focused
business units, C&IS and PFS. Investment management services and products are
provided to the clients of these business units by NTGI. Operating and systems
support is provided to each of the business units by WWOT. Each of these four
business units has a president who reports to Mr. Osborn. For financial
management reporting purposes, the operations of NTGI and WWOT are allocated to
the two principal business units. The Risk Management Unit includes the
Treasury Department and also reports directly to Mr. Osborn. Mr. Osborn has
been identified as the chief operating decision maker because he has final
authority over resource allocation decisions and performance assessment.
       Business unit results are presented in order to promote a greater
understanding of their financial performance. The information, presented on an
internal management-reporting basis, is derived from internal accounting
systems that support the strategic objectives and management structure.
Management has developed accounting systems to allocate revenue and expenses
related to each segment, as well as certain corporate support services,
worldwide operations and systems development expenses. The management reporting
systems also incorporate processes for allocating assets, liabilities and the
applicable interest income and expense. Tier 1 and tier 2 capital are allocated
based on the federal risk-based capital guidelines at a level that is
consistent with Northern Trust's consolidated capital ratios, coupled with
management's judgment of the operational risks inherent in the business.
Allocations of capital and certain corporate expenses may not be representative
of levels that would be required if the segments were independent entities. The
accounting policies used for management reporting are the same as those
described in "Accounting Policies," in the Notes to Consolidated Financial
Statements. Transfers of income and expense items are recorded at cost; there
is no intercompany profit or loss on sales or transfers between business units.
Northern Trust's presentations are not necessarily consistent with similar
information for other financial institutions. For management reporting
purposes, certain corporate income and expense items are not allocated to the
business units and are presented as part of "Treasury and Other." These items
include the impact of long-term debt, preferred equity, holding company
investments, and certain corporate operating expenses.
   The following table summarizes the consolidated results of operations of
Northern Trust. This information is followed by the earnings contribution of
the two principal business segments for the years ended December 31, 2002, 2001
and 2000 on the basis described above.

compared with $225.4 million in 2001 which was down 10% from $249.2 million in
2000. The decline in net income for 2002 was primarily driven by lower trust
fees and foreign exchange trading profits. Trust fees decreased 2% and
represented 60% of total C&IS revenues in 2002 compared with 58% in 2001.

Management's Discussion and Analysis of
Financial Condition and Results of Operations


   Trust assets and trust fees have been impacted by lower market values of
assets under administration offset by net new business sold. The level of net
new business in 2002 was negatively impacted by the loss of two large custody
clients through the periodic rebidding process and the loss of several other
clients due to mergers and acquisitions.
   The decline in other noninterest income in 2002 resulted primarily from
lower levels of foreign exchange trading profits and trust deposit-related
revenues. Partially offsetting the above was an 8% increase in treasury
management fees, higher levels of loan service and letter of credit fees, and
an increase in gains on the sale of lease residuals. The prior year included a
$9.2 million nonrecurring gain on the sale of an 80% interest in Northern
Trust's lockbox operations. Net interest income decreased 9% in 2002. The
current year decline was driven by a 4% decline in average earning assets and a
decrease in the net interest margin to 1.23% from 1.30% last year. The majority
of the decline in earning assets was concentrated in average loans, which were
11% lower than last year. Earning assets in 2001 were up 5% from 2000 primarily
the result of growth in loans and money market assets; however, the net
interest margin declined 7 basis points to 1.30%. The higher provision for
credit losses in 2001 was associated primarily with charge-offs taken on
Enron-related credits and additional provisions necessary on credits to clients
with exposure to asbestos claims.
   Total noninterest expenses of C&IS, which include both the direct expenses
of the business unit and indirect expense allocations from NTGI and WWOT for
product and operating support, increased 2% in 2002 and 6% in 2001. The growth
in expenses reflects increased costs associated with payments made for
receivables management and lockbox services, technology investments, relocation
of London Branch staff to Canary Wharf and higher operating costs to support
business growth. Partially offsetting the impact of this expense growth were
lower levels of performance-based compensation and the impact of adopting new
accounting requirements in 2002 to eliminate goodwill amortization costs.
Goodwill assets allocated to C&IS at December 31, 2002 totaled $42.1 million.

Personal Financial Services. The PFS business unit, under the direction of Mark
Stevens, President--PFS, provides personal trust, custody and investment
management services, individual retirement accounts, guardianship, estate
administration, banking (including private banking) and residential mortgage
lending offered through the Bank in Illinois and affiliates in 11 other states.
PFS focuses on high net worth individuals, executives, retirees and
small/mid-size businesses in each banking subsidiary's target market.
Generally, the financial needs of individuals and families with assets
exceeding $100 million are served through its Wealth Management Group.
   PFS net income totaled $253.1 million in 2002, a decrease of 2% from 2001,
which in turn was 4% below the net income achieved in 2000. Slowing revenue
growth due to the continued decline in the equity markets, combined with a 2%
increase in expenses, partly offset by a decrease in the provision for credit
losses, contributed to the year-to-year decline. The decline in 2001 earnings
was attributed primarily to a 5% increase in operating expenses and an increase
in the provision for credit losses compared with 2000. A summary of trust fees
and trust assets by state and for Wealth Management follows.

   A significant portion of PFS growth has come from adding business in
established locations. This growth has been supplemented by expansion within
existing and new markets. From its 82 office network, Northern Trust is in
close proximity to approximately 30% of the nation's high net worth households,
defined as those with at least $1 million of investable assets. Northern Trust
plans to continue its expansion in existing and new markets with promising
demographics. It is currently estimated that there will be approximately 100
PFS offices in as many as 15 states by the end of 2005.
   The decrease in other noninterest revenues in 2002 was primarily due to the
$15.0 million write-off of the investment in myCFO, Inc. Driven primarily by
growth in residential real estate lending, net interest income increased 4% in
2002 and totaled $447.6 million. In addition, the net interest margin improved
to 3.08% from 3.01% last year. In 2001, net interest income totaled $428.9
million and increased 4% over 2000. The higher provision for credit losses in
2001 primarily reflects the impact of one middle market client that filed for
bankruptcy protection in that year.
   PFS noninterest expenses, which include both the direct expenses of the
business unit and indirect expense allocations from NTGI and WWOT for product
and operating support, increased 2% in 2002 and 5% in 2001. The increase in
2002 expenses primarily reflects merit increases, higher employee benefit
charges, processing errors incurred in servicing and managing financial assets
and performing banking activities, in addition to higher operating costs to
support business growth. Partially offsetting the above was a reduction in
performance-based compensation and the impact of adopting new accounting
requirements in 2002 to eliminate goodwill amortization costs. Goodwill assets
allocated to PFS at December 31, 2002 totaled $48.0 million.

Treasury and Other. The Risk Management Unit, under the direction of Perry R.
Pero, Vice Chairman and Chief Financial Officer, includes the treasury
function. The Treasury Department is responsible for managing the Bank's
wholesale funding, capital position and interest rate risk, as well as the
portfolio of interest rate risk management instruments under the direction of
the Corporate Asset and Liability Policy Committee. The Treasury Department is
also responsible for the investment portfolios of the Corporation and the Bank
and provides investment advice and management services to the subsidiary banks.
"Other" corporate income and expenses represent items that are not allocated to
the business units and generally represent certain nonrecurring items and
certain executive level compensation.
   The decrease in other noninterest income is primarily due to the $4.8
million write-off of the investment in the Global Straight Through Processing
Association. The improvement in net interest income in both 2002 and 2001 is
primarily a result of lower interest rates, which reduced the funding costs
allocated to corporate centers.
   Noninterest expenses totaled $28.3 million for 2002, $2.5 million or 8%
below the 2001 level. Increases in expenses incurred for professional services
were more than offset by a reduction in the cost for certain executive level
compensation plans. The $46.1 million decrease in noninterest expenses in 2001
was the result of several factors. Record profits and the significant increase
in the price of Northern Trust Corporation common stock during 2000 drove up
certain executive level incentive compensation that year. Expenses were also
reduced due to lower stock-related directors' compensation resulting

from the decline in the price of Northern Trust Corporation common stock in
2001. In addition, year 2000 expenses were higher than 2001 due to expenses
relating to the purchase of the technology center in January 2000, lease
termination costs associated with the then planned relocation of staff in
London and the earlier than anticipated retirement of certain Bank officers.

Northern Trust Global Investments. The NTGI business unit, under the direction
of Stephen B. Timbers, President--NTGI, provides a broad range of investment
management and related services and products to domestic and international
clients of C&IS and PFS through various subsidiaries of the Corporation.
Clients include institutional and individual separately managed accounts, bank
common and collective funds, registered investment companies, non-U.S.
collective investment vehicles and unregistered private investment funds,
including funds of funds. NTGI offers both active and passive equity and fixed
income portfolio management, as well as traditional multi-manager products and
services. NTGI's activities also encompass brokerage, securities lending and
related services. NTGI's international relationships include joint ventures,
alliances and distribution arrangements with entities in the United Kingdom,
Ireland, Germany, Japan and the Cayman Islands. The revenues and expenses of
this business unit are fully allocated to C&IS and PFS.

Worldwide Operations and Technology. The WWOT business unit, under the
direction of Timothy J. Theriault, President--WWOT, supports all of Northern
Trust's business activities, including the sales, relationship management,
asset management, securities lending, transaction processing and product
management activities of C&IS, PFS and NTGI. These activities are conducted
principally in the operations and technology centers in Chicago and London. The
Northern Trust Company of New York is also part of this unit. The expenses of
this business unit are fully allocated to other business units.

Subsequent Implementation of Accounting Standards
In June 2002, the Financial Accounting Standards Board (FASB) issued Statement
of Financial Accounting Standards (SFAS) No. 146, "Accounting for Costs
Associated with Exit or Disposal Activities." SFAS No. 146 applies to exit and
disposal costs including: termination benefits provided to current employees
that are involuntarily terminated under the terms of a benefit arrangement
that, in substance, is not an ongoing benefit arrangement or an individual
deferred compensation contract; costs to terminate a contract that is not a
capital lease; and costs to consolidate facilities or relocate employees. This
Statement requires that a liability for cost associated with an exit or
disposal activity be recognized and measured initially at fair value only when
a liability is incurred.
   The provisions of this Statement are effective for exit or disposal
activities that are initiated after December 31, 2002. Northern adopted this
Statement as of January 1, 2003. It is not anticipated that the adoption of
SFAS No. 146 will have a material effect on Northern Trust's results of
operations.
   In November 2002, the FASB issued Interpretation No. 45, "Guarantor's
Accounting and Disclosure Requirements for Guarantees, Including Indirect
Guarantees of Indebtedness of Others." This Interpretation elaborates on the
disclosures to be made by a guarantor in its interim and annual financial
statements about its obligations under certain guarantees that it has issued.
It also clarifies that a guarantor is required to recognize, at the inception
of a guarantee, a liability for the fair value of the obligation undertaken in
issuing the guarantee.
   The initial recognition and initial measurement provisions of this
Interpretation are applicable on a prospective basis to guarantees issued or
modified after December 31, 2002, irrespective of the guarantor's fiscal
year-end. It is not anticipated that adoption of the recognition and
measurement provisions of this Interpretation will have a material effect on
Northern Trust's results of operations. The disclosure requirements in this
Interpretation are effective for financial statements of interim or annual
periods ending after December 15, 2002, and are included in Notes 21 and 22 to
Consolidated Financial Statements on pages 79 through 83 of this Annual Report.
   In January 2003, the FASB issued Interpretation No. 46, "Consolidation of
Variable Interest Entities," (FIN 46). FIN 46 clarifies the application of
Accounting Research Bulletin No. 51, "Consolidated Financial Statements," to
certain entities in which equity investors do not have the characteristics of a
controlling financial interest or do not have sufficient equity at risk for the
entity to finance its activities without additional subordinated financial
support from other parties. Such entities are termed variable interest
entities. The objective of FIN 46 is to improve financial statement
comparability between entities involved in similar activities. FIN 46 sets
forth guidance for the identification of variable interest entities and the
assessment of a company's interests in the variable interest entity in order to
determine whether consolidation of the entity is required.
   The consolidation requirements of FIN 46 apply to all variable interest
entities created after January 31, 2003. Public companies must apply the
consolidation requirements to variable interest entities created before
February 1, 2003 no later than the beginning of the first interim or annual
reporting period

beginning after June 15, 2003. If the variable interests held are considered to
be significant, disclosure requirements are required in all financial
statements issued after January 31, 2003, regardless of when the variable
interest entity was created.
   Northern Trust is currently reviewing the requirements of this
Interpretation. At the present time the exact impact of this Interpretation is
not known and, therefore, cannot be reasonably estimated.

Capital Expenditures
Northern Trust's Management Committee reviews and approves proposed significant
capital expenditures. This process is designed to assure that the major
projects to which Northern Trust commits its resources produce benefits
compatible with corporate strategic goals.
   Capital expenditures in 2002 included ongoing enhancements to Northern
Trust's hardware and software capabilities and expansion or renovation in
several existing offices. Capital expenditures for 2002 totaled $226.9 million,
of which $116.6 million was for software, $63.7 million was for building and
leasehold improvements, $39.8 million for computer hardware and machinery and
$6.8 million for furnishings. These capital expenditures are designed
principally to support and enhance the transaction processing, investment
management and securities handling capability of the trust and banking
businesses, as well as relationship management and client interaction.
Additional capital expenditures planned for systems technology will result in
future expenses for the depreciation of hardware and amortization of software.
Depreciation and software amortization associated with these capital
expenditures are charged to equipment and other operating expenses,
respectively. The unamortized capitalized cost of corporate-wide software
development projects as of December 31, 2002 was $371.1 million, compared with
$329.8 million at the previous year-end.

Risk Management
Asset Quality and Credit Risk Management Securities. Northern Trust maintains a
high quality securities portfolio, with 78% of the total portfolio composed of
U.S. Treasury or federal agency securities. The remainder of the portfolio
consists of obligations of states and political subdivisions, preferred stock
and other securities, including Federal Home Loan Bank stock and Federal
Reserve Bank stock. At December 31, 2002, 81% of these securities were rated
triple-A or double-A, 4% were rated single-A and 15% were below A or not rated
by Standard and Poor's and/or Moody's Investors Service.
   Northern Trust is an active participant in the repurchase agreement market.
This market provides a relatively low cost alternative for short-term funding.
Securities purchased under agreements to resell and securities sold under
agreements to repurchase are recorded at the amounts at which the securities
were acquired or sold plus accrued interest. To minimize any potential credit
risk associated with these transactions, the fair value of the securities
purchased or sold is continuously monitored, limits are set on exposure with
counterparties, and the financial condition of counterparties is regularly
assessed. It is Northern Trust's policy to take possession of securities
purchased under agreements to resell. Securities sold under agreements to
repurchase are held by the counterparty until the repurchase transaction
matures.

Loans and Other Extensions of Credit. Credit risk is inherent in Northern
Trust's various lending activities. Northern Trust focuses its lending efforts
on clients with existing trust or treasury management relationships or who are
looking to build a full range of financial services. Credit risk is managed
through the Credit Policy function, which is designed to assure adherence to a
high level of credit standards. The Credit Policy function reports to the
Corporation's Chief Financial Officer. Credit Policy provides a system of
checks and balances for Northern Trust's diverse credit-related activities by
establishing and monitoring all credit-related policies and practices
throughout Northern Trust and assuring their uniform application. These
activities are designed to diversify credit exposure on an industry and client
basis, thus lessening overall credit risk. These credit management activities
also apply to Northern Trust's use of derivative financial instruments,
including foreign exchange contracts and interest risk management instruments.
       Individual credit authority for commercial and other loans is limited to
specified amounts and maturities. Credit decisions involving commitment
exposure in excess of the specified individual limits are submitted to the
appropriate Credit Approval Committee (Committee). Each Committee is chaired by
the executive in charge of the area and has a Credit Policy officer as a voting
participant. Each Committee's credit approval authority is specified, based on
commitment levels, credit ratings and maturities. Credits involving commitment
exposure in excess of these group credit limits require the approval of the
Senior Credit Committee.
   The Counterparty Risk Management Committee established by Credit Policy
manages counterparty risk. This committee has sole credit authority for
exposure to all foreign banks, certain domestic banks which Credit Policy deems
to be counterparties and which do not have commercial credit relationships
within the Corporation, and certain other exposures.
   Under the auspices of Credit Policy, country exposure limits are reviewed
and approved on a country-by-country basis.

Management's Discussion and Analysis of
Financial Condition and Results of Operations

   As part of Northern Trust's ongoing credit granting process, internal credit
ratings are assigned to each client and credit before credit is extended, based
on an assessment of creditworthiness. Credit Policy performs at least annually,
a review of selected significant credit exposures to identify at the earliest
possible stages, clients who might be facing financial difficulties. Internal
credit ratings are also reviewed during this process. Above average risk loans
receive special attention by both lending officers and Credit Policy. This
approach allows management to take remedial action in an effort to deal with
potential problems.
       An integral part of the Credit Policy function is a formal review of
past due and potential problem loans to determine which credits, if any, need
to be placed on nonaccrual status or charged off. As more fully described on
pages 50 through 53, the provision for credit losses is reviewed quarterly to
determine the amount necessary to maintain an adequate reserve for credit
losses.
   A further way in which credit risk is managed is by requiring collateral.
Management's assessment of the borrower's creditworthiness determines whether
collateral is obtained. The amount and type of collateral held varies but may
include deposits held in financial institutions, U.S. Treasury securities,
other marketable securities, income-producing commercial properties, accounts
receivable, property, plant and equipment, and inventory. Collateral values are
monitored on a regular basis to ensure that they are maintained at an
appropriate level.
       The largest component of credit risk relates to the loan portfolio. In
addition, credit risk is inherent in certain contractual obligations such as
legally binding unfunded commitments to extend credit, commercial letters of
credit and standby letters of credit. These contractual obligations and
arrangements are discussed in Note 21 and are presented in the tables that
follow.

   Although credit exposure is well diversified, there are certain groups of
loans that meet the accounting definition under SFAS No. 107 of credit risk
concentrations. According to this statement, group concentrations of credit
risk exist if a number of borrowers or other counterparties are engaged in
similar activities and have similar economic characteristics that would cause
their ability to meet contractual obligations to be similarly affected by
changes in economic or other conditions. The fact that an extension of credit
falls into one of these groups does not necessarily indicate that the credit
has a higher than normal degree of credit risk. These groups are: residential
real estate, middle market companies and small businesses, banks and bank
holding companies, commercial real estate and commercial aircraft leases.
   Residential Real Estate. The residential real estate loan portfolio totaled
$7.8 billion or 44% of total domestic loans at December 31, 2002, compared with
$7.4 billion or 43% at December 31, 2001. Residential real estate loans consist
of conventional home mortgages and equity credit lines, which generally require
a loan to collateral value of no more than 75% to 80% at inception.
   Of the total $7.8 billion in residential real estate loans, $3.5 billion
were in the greater Chicago area with the remainder distributed throughout the
other geographic regions served by Northern Trust. Legally binding commitments
to extend credit, which are primarily equity credit lines, totaled $1.2 billion
and $978.1 million as of December 31, 2002 and 2001, respectively.

Management's Discussion and Analysis of
Financial Condition and Results of Operations

   Middle Market Companies and Small Businesses. Credit exposure to middle
market companies and small businesses is primarily in the form of commercial
loans, which totaled $1.9 billion at December 31, 2002 and $2.2 billion at
December 31, 2001. These loans are to a diversified group of borrowers that are
predominantly in the manufacturing, wholesaling, distribution and services
industries, most of which have total annual sales of less than $500 million.
The largest component of this group of borrowers is located in the mid-western
areas served by the Bank. Middle market and small businesses have been an
important focus of Northern Trust's business development efforts both for
commercial banking and personal trust/private banking services and it is part
of the strategic plan to continue to selectively grow the portfolio with such
entities. The credit risk associated with middle market and small business
lending is principally influenced by general economic conditions and the
resulting impact on the borrower's operations.
   Legally binding commitments to extend credit, standby letters of credit, and
commercial letters of credit to middle market companies and small businesses
totaled $2.9 billion, $1.4 billion, and $16.3 million, respectively, as of
December 31, 2002, and $2.9 billion, $1.3 billion, and $16.5 million,
respectively, as of December 31, 2001.
   Banks and Bank Holding Companies. On-balance sheet credit risk to banks and
bank holding companies, both domestic and international, totaled $10.8 billion
and $10.7 billion at December 31, 2002 and 2001, respectively. The majority of
this exposure consisted of short-term money market assets, which totaled $9.2
billion at both December 31, 2002 and December 31, 2001, and
noninterest-bearing demand balances maintained at correspondent banks which
totaled $1.2 billion at both year-ends. Commercial loans to banks totaled
$137.8 million and $223.9 million, respectively, as of December 31, 2002 and
2001. The majority of these loans were to U.S. bank holding companies,
primarily in the seventh Federal Reserve District, for their acquisition and
other corporate purposes. Such lending activity is limited to entities, which
have a substantial business relationship with Northern Trust. At December 31,
2002, legally binding commitments to extend credit and standby letters of
credit to banks and bank holding companies totaled $178.3 million and $3.3
million, respectively. At December 31, 2001, legally binding commitments were
$186.1 million and standby letters of credit were $10.4 million.
   Commercial Real Estate. In managing its credit exposure, management has
defined a commercial real estate loan as one where: (1) the borrower's
principal business activity is the acquisition or the development of real
estate for commercial purposes; (2) the principal collateral is real estate
held for commercial purposes, and loan repayment is expected to flow from the
operation of the property; or (3) the loan repayment is expected to flow from
the sale or refinance of real estate as a normal and ongoing part of the
business. Unsecured lines of credit to firms or individuals engaged in
commercial real estate endeavors are included without regard to the use of loan
proceeds. The commercial real estate portfolio consists of interim loans and
commercial mortgages.
   Short-term interim loans provide financing for the initial phases of the
acquisition or development of commercial real estate, with the intent that the
borrower will refinance the loan through another financial institution or sell
the project upon its completion. The interim loans are primarily in those
markets where Northern Trust has a strong presence and a thorough knowledge of
the local economy. The interim loans, which totaled $388.1 million and $342.0
million as of December 31, 2002 and 2001, respectively, are composed primarily
of loans to developers that are highly experienced and well known to Northern
Trust.
   Commercial mortgage financing, which totaled $780.4 million and $683.6
million as of December 31, 2002 and 2001, respectively, is provided for the
acquisition of income producing properties. Cash flows from the properties
generally are sufficient to amortize the loan. These loans average less than
$500,000 each and are primarily located in the suburban Chicago and Florida
markets.
   At December 31, 2002, legally binding commitments to extend credit and
standby letters of credit to commercial real estate developers totaled $254.2
million and $123.1 million, respectively. At December 31, 2001, legally binding
commitments were $79.4 million and standby letters of credit were $12.7 million.
   Commercial Aircraft Leases. Through its leasing subsidiary, Norlease, Inc.,
Northern Trust has entered into leveraged lease transactions involving
commercial aircraft totaling $240 million, which are a part of the $1.3 billion
Lease Financing portfolio at December 31, 2002. $139 million of the leveraged
leases involve aircraft leases to foreign airlines, where the leases are fully
backed by a combination of pledged marketable securities and guarantees from
either a domestic "AAA" rated insurance company or a large U.S.-based banking
institution. $10 million represents leases to domestic airlines; $71 million to
commercial transport companies; and, the balance for commuter aircraft leases,
the last of which are guaranteed by aircraft manufacturers or by sovereign
entities.

Foreign Outstandings. As used in this discussion, foreign outstandings are
cross-border outstandings as defined by the Securities and Exchange Commission.
They consist of loans, acceptances, interest-bearing deposits with financial
institutions, accrued interest and other monetary assets. Not included are
letters of credit, loan commitments, and foreign office local currency claims
on residents funded by local currency liabilities. Foreign outstandings related
to a specific country are net of guarantees given by third parties resident
outside the country and the value of tangible, liquid collateral held outside
the country. However, transactions with branches of foreign banks are included
in these outstandings and are classified according to the country location of
the foreign banks' head office.
       Short-term interbank time deposits with foreign banks represent the
largest category of foreign outstandings. The Chicago head office and the
London Branch actively participate in the interbank market with U.S. and
foreign banks. In recent years, international commercial lending activities
have been focused on import and export financing for U.S.-based clients.
   Northern Trust places deposits with counterparties that have high internal
(Northern Trust) and external credit ratings. These foreign banks are approved
and monitored by Northern Trust's Counterparty Risk Management Committee. The
Committee has credit authority for exposure to all foreign banks and employs a
review process that results in credit limits. This process includes financial
analysis of the foreign banks, use of an internal rating system and
consideration of external ratings from rating agencies. Each counterparty is
reviewed at least annually. Separate from the entity-specific review process,
the average life to maturity of deposits with foreign banks is deliberately
maintained on a short-term basis in order to respond quickly to changing credit
conditions. Additionally, the Committee performs a country-risk analysis and
imposes limits to country exposure. The following table provides information on
foreign outstandings by country that exceed 1.00% of Northern Trust's assets.

Nonperforming Assets and 90 Day Past Due Loans. Nonperforming assets consist of
nonaccrual loans, restructured loans and Other Real Estate Owned (OREO). OREO
is comprised of commercial and residential properties acquired in partial or
total satisfaction of problem loans. Past due loans are loans that are
delinquent 90 days or more and still accruing interest. The level of 90 day
past due loans at any reporting period can fluctuate widely based on the timing
of cash collections, renegotiations and renewals.
   Maintaining a low level of nonperforming assets is important to the ongoing
success of a financial institution. In addition to the negative impact on both
net interest income and credit losses, nonperforming assets also increase
operating costs due to the expense associated with collection efforts. Northern
Trust's comprehensive credit review and approval process is critical to the
ability to minimize nonperforming assets on a long-term basis.
   The table above presents the nonperforming assets and past due loans for the
current year and prior years. Of the total loan portfolio of $18.1 billion at
December 31, 2002, $93.4 million or .5% was nonaccrual, a decrease of $15.3
million from year-end 2001. Nonaccrual loans at the end of 2002 include $40.5
million to two asbestos producers that have filed for Chapter 11 reorganization.
   Included in the portfolio of nonaccrual loans are those which meet the
criteria as being "impaired" under the definition in SFAS No. 114. A loan is
impaired when, based on current information and events, it is probable that a
creditor will be unable to collect all amounts due according to the contractual
terms of the loan agreement. As of December 31, 2002, impaired loans, all of
which have been classified as nonaccrual, totaled $90.9 million, net of $23.0
million in charge-offs. These loans had $25.0 million of the reserve for credit
losses allocated to them.

Provision and Reserve for Credit Losses. Changes in the reserve for credit
losses were as follows:

              ----------------------------------------------------
              Balance at End of Year...... $168.5  $161.6  $162.9


   The provision for credit losses is the charge against current earnings that
is determined by management, through a disciplined credit review process, to be
the amount needed to maintain a reserve that is sufficient to absorb credit
losses inherent in Northern Trust's loan and lease portfolios and other credit
undertakings. The reserve provides for probable losses that have been
identified with specific borrower relationships (specific loss component) and
for probable losses that are believed to be inherent in the loan and lease
portfolios and other credit undertakings but that have not yet been
specifically identified (inherent loss component). The table on page 52 shows
(i) the specific portion of the reserve, (ii) the allocated portion of the
inherent reserve and its components by loan category and (iii) the unallocated
portion of the reserve at December 31, 2002 and each of the prior four
year-ends.
   Specific Component of the Reserve. The specific component of the reserve is
determined on a loan-by-loan basis as part of the regular review of impaired
loans and potential charge-offs. The specific reserve is based on a loan's
current book value compared to the present value of its projected future cash
flows, collateral value or market value, as is relevant for the particular loan.

Management's Discussion and Analysis of
Financial Condition and Results of Operations

   At December 31, 2002, the specific reserve component amounted to $25.0
million compared with $21.1 million at the end of 2001. The increase was
primarily caused by several middle market loans significantly impacted by the
continued economic downturn. Specific reserves related to $40.5 million in
nonperforming loans to two asbestos producers were established based on market
values provided by debt trading desks of major investment banking firms.
   The decrease in the specific loss component of the reserve in the prior year
from $24.3 million in 2000 to $21.1 million in 2001 was primarily caused by the
writedown and sale of certain large commercial loans during the year and the
successful workout of one large middle market loan. These were partially offset
by additional reserves provided on certain large commercial loans with
increased exposure to potential asbestos-related claims, and on several middle
market loans impacted by the economic downturn.
   Allocated Inherent Component of the Reserve. The allocated portion of the
inherent reserve is based on management's review of historical charge-off
experience as well as its judgment regarding loans in each credit rating
category over a period of time that management determines is adequate to
reflect longer-term economic trends. One building block in reaching the
appropriate allocated inherent reserve is an analysis of loans by credit rating
categories. Credit ratings are determined by members of the Credit Policy Group
at the time each loan is approved. These credit ratings are then subject to
periodic reviews by the Credit Policy Group, which is independent of business
unit management. Credit Policy makes the final determination of each loan's
rating. Credit ratings range from "1" for the strongest credits to "9" for the
weakest credits; a "9" rated loan would normally represent a complete loss.
   Several factors are considered by management to determine the level of the
allocated inherent component of the reserve. One of the factors is the
historical loss ratio for each credit rating category over the prior five
years. The historical loss ratios are evaluated by management and adjusted
based on current facts and circumstances. The historical loss factors on
higher-risk loans, those rated "5" through "8", are also refined by considering
historical loss ratios and regulatory guidelines in order to provide a more
consistent and reliable method for taking account of credit trends in measuring
loss exposure.
   Management also maintains a reserve for the commercial, commercial real
estate and international segments of the portfolio that have credit ratings
from "1" through "4", in order to measure the loss estimated to be inherent in
these riskier segments. Because of the higher degree of uncertainty in these
portfolios and Northern Trust's past experience, which included significant
losses in brief periods at particular points in the economic cycles, management
believes it appropriate to use a reserve higher than recent charge-off
experience would suggest. This is intended to prevent an understatement of
reserves based upon over-reliance on more favorable economic conditions
included in the historic look-back period.
   The allocated inherent component of the reserve also covers the credit
exposure associated with undrawn loan commitments and standby letters of
credit. To determine the exposure on these instruments, management uses the
factors applied in risk-based capital calculations to determine the balance
sheet equivalent amount and assigns a reserve provision factor based on the
methodology utilized for outstanding loans.
   The allocated portion of the inherent reserve increased $5.4 million to
$123.4 million at December 31, 2002 compared with $118.0 million at December
31, 2001. The increase in this component of the reserve primarily reflects the
net impact of credit rating changes on several commercial loans that were
lowered due to the decline in their credit quality primarily resulting from the
slowdown in the economy. The changes in the credit ratings are a reflection of
Northern Trust's most recent evaluations and the results of the annual,
industry-wide Shared National Credit review conducted by the banking regulators.
   In 2001, the credit rating on one large performing loan was lowered due to
the borrower's exposure to potential asbestos-related claims. Also, as a result
of management's periodic review of all loss factors utilized in estimating the
allocated inherent reserve, during 2001 certain loss factors applied primarily
to commercial loans and off-balance sheet exposures were reduced. The loss
factor adjustments reflect management's assessment of the credit risk inherent
for these categories and their historical loss experience.
   Management does not believe that the circumstances that caused credit losses
in 2001 and 2002 on the Enron Corp. loans, or on loans to clients exposed to
asbestos-related claims, are indicative of the credit risk in the remainder of
the loan portfolio. As a result, management did not adjust the historic loss
ratios which are used, in part, to determine the allocated inherent component
of the reserve for these specific events.
       Unallocated Inherent Component of the Reserve. The unallocated portion
of the inherent loss reserve is based on management's review of other factors
affecting the determination of probable losses inherent in the portfolio, which
are not necessarily captured by the application of historical loss ratios. This
portion of the reserve analysis involves the exercise of judgment and reflects
considerations such as management's view that the reserve should have a margin
that recognizes the imprecision inherent in the process of estimating expected
credit losses.

   In evaluating the level of the unallocated portion of the reserve in 2002,
management concluded that there were no significant changes in concentration of
credits that impacted asset quality that had not been recognized in the
specific and allocated components of the reserve. In addition, loan growth
during the year came primarily in low-risk residential mortgage loans, while
there was a decline in the level of commercial loans outstanding. Based on
these factors and management's current evaluation of the overall quality of the
portfolio, the unallocated portion of the reserve was lowered from $22.5
million to $20.1 million.
       Other Factors. The total amount of the two highest risk loan groupings,
those rated "7" and "8" (based on Northern Trust's internal rating scale, which
closely parallels that of the banking regulators), increased $21 million to
$316 million, of which $90.8 million was classified as impaired. This compares
with $295 million last year-end when $97.6 million was classified as impaired.
The increase primarily reflects deterioration and downgrade of certain large
commercial and middle market loans, due to the slowdown in the economy, offset
in part by the sale of loans, one made to Enron Corp. and another to a large
commercial client that had exposure to asbestos-related claims, and by
significant repayments during the year of certain large commercial and middle
market loans. There were no "9" rated loans reported at any time during the
periods because loans are charged-off when they are so rated. At December 31,
2002, these highest risk loans represent 1.8% of outstanding loans.
   Overall Reserve. Management's evaluation of the factors above resulted in a
reserve for credit losses of $168.5 million at December 31, 2002 compared with
$161.6 million at the end of 2001. The reserve of $161.1 million assigned to
loans and leases, as a percentage of total loans and leases was .89% at
December 31, 2002, compared with .86% at December 31, 2001. This reserve level
recognizes the fact that a significant part of the growth in Northern Trust's
loan portfolio continues to be in lower-risk residential mortgage loans and
collateralized personal loans.
       Although Northern Trust analyzes its exposure to credit losses from both
on- and off-balance sheet activity as one process, during 2002 it has segmented
the two and has added a section to the above allocation table to identify that
portion of the reserve assigned to loans and leases outstanding, versus the
portion assigned to unfunded commitments, standby letters of credit and
derivatives. For financial reporting purposes, the portion assigned to loans
and leases is reported as a contra asset, directly following the loans and
leases line on the Corporation's Consolidated Balance Sheet, while that
assigned to the off-balance sheet activity is included in Other Liabilities.
   Reserves assigned to unfunded loan commitments, standby letters of credits
and derivative products totaled $7.4 million at December 31, 2002, compared
with $7.3 million at December 31, 2001.

   Provision. The resulting provision for credit losses was $37.5 million for
the year, while net charge-offs totaled $30.6 million. This compares with a
provision for credit losses of $66.5 million and net charge-offs of $67.8
million in 2001. In 2002, in addition to the factors which led to increases in
the specific and allocated inherent portions of the reserve, deterioration in
other loans and leases occurred during the year that required additional
provisions and related charge-offs. Included was a leveraged lease transaction
involving United Airlines, which filed for Chapter 11 bankruptcy protection in
December 2002, and the charge-off of the remaining unsecured Enron Corp.
exposure. In 2001, $45.0 million of the provision was taken in the fourth
quarter to address credit exposure to Enron Corp., which filed for bankruptcy
in December 2001, as well as other credit risks stemming from the economic
recession. Approximately $24.0 million of the 2001 credit loss provision and
charge-offs were related to the Enron Corp. bankruptcy filing.

Market Risk Management
Overview. The Board of Directors has overall responsibility for Northern
Trust's interest rate and foreign exchange risk management policies. To ensure
adherence to these policies, the Corporate Asset and Liability Policy Committee
(ALCO) establishes and monitors guidelines to control the sensitivity of
earnings to changes in interest rates. The guidelines apply to both on- and
off-balance sheet positions. ALCO also establishes and monitors limits for
foreign exchange risk. The goal of the ALCO process is to maximize earnings
while maintaining a high quality balance sheet and carefully controlling
interest rate and foreign exchange risk.

Asset/Liability Management. Asset/liability management activities include
lending, accepting and placing deposits, investing in securities, issuing debt,
and hedging interest rate risk with off-balance sheet instruments. The primary
market risk associated with asset/liability management activities is interest
rate risk. Sensitivity of earnings to interest rate changes arises when yields
on assets change in a different time period or in a different amount from that
of interest costs on liabilities. To mitigate interest rate risk, the structure
of the balance sheet is managed so that movements of interest rates on assets
and liabilities (adjusted for off-balance sheet hedges) are highly correlated
and contribute to earnings even in periods of volatile interest rates.
       Northern Trust utilizes the following measurement techniques in the
management of interest rate risk: simulation of earnings; simulation of the
economic value of equity; and gap analysis. These three techniques are
complementary and are used in concert to provide a comprehensive interest rate
risk management capability.
   Simulation of earnings is the primary tool used to measure the sensitivity
of earnings to interest rate changes. Using computer-modeling techniques,
Northern Trust is able to measure the potential impact of different interest
rate assumptions on pre-tax earnings. All on-balance sheet positions, as well
as derivative financial instruments (principally interest rate swaps) that are
used to manage interest rate risk, are included in the model simulation.
   Northern Trust used model simulations to measure its earnings sensitivity
relative to management's most likely interest rate scenarios as of December 31,
2002 and December 31, 2001. Similar to the prior year simulation, the 2003
interest rate scenario assumes a stable interest rate environment during the
first half of the year, with moderately rising interest rates for the remainder
of the year. The interest sensitivity was tested by running alternative
scenarios above and below the most likely interest rate outcome. The table on
the following page shows the effect on 2003 pre-tax earnings of 100 and 200
basis point upward and 100 basis point downward movements in interest rates
relative to management's interest rate assumptions. The effect on 2002 pre-tax
earnings reflects 100 and 200 basis point upward and downward movements in
interest rates relative to management's interest rate assumptions. Each of the
movements in interest rates was assumed to have occurred gradually over a
one-year period. The 100 basis point increase, for example, consisted of twelve
consecutive monthly increases of 8.3 basis points. The following assumptions
were also incorporated into the model simulations:
  .  the balance sheet size was assumed to remain constant over the one year
     simulation horizon;
  .  maturing assets and liabilities were invested or deposited into identical
     items with the same term;
  .  prepayments on mortgage loans were projected under each rate scenario
     using a mortgage analytics system that incorporated market prepayment
     assumptions; and
  .  changes in the spreads between retail deposit rates and asset yields were
     estimated based on historical patterns and current competitive trends.

   *With the targeted federal funds rate at year-end 2002 at 1.25%, a scenario
of decreasing interest rates by 200 basis points was not considered reasonable
and therefore not presented.

   The simulations of earnings do not incorporate any management actions that
might moderate the negative consequences of interest rate deviations. For that
reason and others, they do not reflect likely actual results but serve as
conservative estimates of interest rate risk.
   A second technique used to measure interest rate risk is simulation of the
economic value of equity, which provides estimates of the potential future
impact on equity of various changes in interest rates. The potential effect of
interest rate changes on equity is derived from the impact of such changes on
the market values of assets, liabilities and off-balance sheet instruments.
Northern Trust limits aggregate market risk, as measured in this fashion, to an
acceptable level within the context of risk-return trade-offs.
       The third technique that is used to measure interest rate risk is gap
analysis. The calculation of the interest sensitivity gap measures the timing
mismatches between assets and liabilities. This interest sensitivity gap is
determined by subtracting the amount of liabilities from the volume of assets
that reprice in a particular time interval. A liability sensitive position
results when more liabilities than assets reprice or mature within a given
period. Under this scenario, as interest rates decline, increased net interest
revenue will be generated. Conversely, an asset sensitive position results when
more assets than liabilities reprice within a given period; in this instance,
net interest revenue would benefit from an increasing interest rate
environment. The economic impact of creating a liability or asset sensitive
position depends on the magnitude of actual changes in interest rates relative
to the current expectations of market price participants.
   A variety of actions are used to implement risk management strategies
including:
  .  purchases of securities;
  .  sales of securities that are classified as available for sale;
  .  sales of held for sale residential real estate loans;
  .  issuance of senior notes and subordinated notes;
  .  collateralized borrowings from the Federal Home Loan Bank;
  .  placing and taking Eurodollar time deposits; and
  .  hedging with various types of derivative financial instruments.
   Northern Trust strives to use the most effective instruments for
implementing its interest risk management strategies, considering the costs,
liquidity, collateral and capital requirements of the various alternatives.

Foreign Exchange Trading. Foreign exchange trading activities consist
principally of providing foreign exchange services to clients. Most of these
services are provided in connection with Northern Trust's growing global
custody business. However, in the normal course of business Northern Trust also
engages in proprietary trading of foreign currencies. The primary market risk
associated with these activities is foreign exchange risk.
   Foreign currency positions exist when aggregate obligations to purchase and
sell a currency other than the U.S. dollar do not offset each other, or offset
each other in different time periods and also include holdings of foreign
denominated non-trading assets and liabilities that are not converted to U.S.
dollars through the use of hedge contracts. Northern Trust mitigates the risk
related to its foreign currency positions by establishing limits on the amounts
of, and durations of its positions. The limits on overnight inventory positions
are generally lower than the limits established for intra-day trading activity.
All overnight positions are monitored by a risk management function, which is
separate from the trading function, to ensure that the limits are not exceeded.
Although position limits are important in controlling foreign exchange risk,
they are not a substitute for the experience or judgment of Northern Trust's
senior management and its foreign currency traders, who have extensive
knowledge of the foreign currency markets. Foreign currency positions and
strategies are adjusted as needed in response to changing market conditions.
   As part of its risk management activities, Northern Trust regularly measures
the risk of loss associated with foreign currency positions using a value at
risk model. This statistical model provides an estimate, based on a 95%
confidence level, of the potential loss in earnings that may be incurred if an

adverse one-day shift in foreign currency exchange rates were to occur. The
model, which is based on a variance/co-variance methodology, incorporates
historical currency price data and historical correlations in price movement
among the currencies. All foreign currency positions, including foreign
denominated non-trading assets and liabilities that were not converted to U.S.
dollars through the use of hedge contracts, are included in the model.
   Northern Trust's value at risk based on foreign currency positions totaled
$57 thousand and $85 thousand as of December 31, 2002 and 2001, respectively.
Value at risk totals representing the average, high and low for 2002 were $199
thousand, $390 thousand and $57 thousand, respectively, with the average, high
and low for 2001 being $233 thousand, $463 thousand and $85 thousand,
respectively. These totals indicate the degree of risk inherent in foreign
currency positions as of year-end and during the year; however, it is not a
prediction of an expected gain or loss. Actual future gains and losses will
vary depending on market conditions and the size and duration of future foreign
currency positions.

Other Trading Activities. Market risk associated with other trading activities
is negligible. Northern Trust is a party to various derivative financial
instruments, most of which consist of interest rate swaps entered into to meet
clients' interest risk management needs. When Northern Trust enters into such
swaps, its policy is to mitigate the resulting interest rate risk with an
offsetting swap or with futures contracts. Northern Trust carries in its
trading portfolio a small inventory of securities that are held for sale to its
clients. The interest rate risk associated with these securities is
insignificant.

Liquidity Risk Management
The objectives of liquidity risk management are to ensure that Northern Trust
can meet its cash flow requirements and to capitalize on business opportunities
on a timely and cost effective basis. Management monitors the liquidity
position on a daily basis to make funds available at a minimum cost to meet
loan and deposit cash flows. The liquidity profile is also structured so that
the capital needs of the Corporation and its banking subsidiaries are met.
Management maintains a detailed liquidity contingency plan designed to
adequately respond to dramatic changes in market conditions.
   Liquidity is secured by managing the mix of items on the balance sheet and
expanding potential sources of liquidity. The balance sheet sources of
liquidity include the short-term money market portfolio, unpledged available
for sale securities, maturing loans and the ability to securitize a portion of
the loan portfolio. Further, liquidity arises from the diverse funding base and
the fact that a significant portion of funding comes from clients that have
other relationships with Northern Trust.
   A significant source of liquidity is the ability to draw funding from both
domestic and international markets. The Bank's senior long-term debt is rated
AA- by Standard & Poor's, Aa3 by Moody's Investors Service, and AA by Fitch.
These ratings allow the Bank to access capital markets on favorable terms.
       Northern Trust maintains a liquid balance sheet with loans representing
only 46% of total assets. Further, at December 31, 2002, it had a significant
liquidity reserve on its balance sheet in the form of cash and due from banks,
securities available for sale, and money market assets, which in aggregate
totaled $17.7 billion or 45% of total assets. Northern Trust has not utilized
unconsolidated special purpose vehicles for financing purposes or as part of
its liquidity risk management.
   The Corporation's uses of cash consist mainly of dividend payments to the
Corporation's common and preferred stockholders, the payment of principal and
interest to note holders, purchases of its common stock and acquisitions. These
cash needs are met largely by dividend payments from its subsidiaries, and by
interest and dividends earned on investment securities and money market assets.
Bank subsidiary dividends are subject to certain restrictions that are
explained in Note 15 on page 75. Bank subsidiaries have the ability to pay
dividends during 2003 equal to their 2003 eligible net profits plus $378.9
million. The Corporation's liquidity, defined as the amount of marketable
assets in excess of commercial paper, was strong at $163.2 million at year-end
2002. The cash flows of the Corporation are shown in Note 29 on page 89. The
Corporation also has a $50 million back-up line of credit for its commercial
paper issuance.

Capital Management
One of management's primary objectives is to maintain a strong capital position
to merit the confidence of clients, the investing public, bank regulators and
stockholders. A strong capital position helps Northern Trust take advantage of
profitable investment opportunities when they arise and helps withstand
unforeseen adverse developments. In 2002, capital levels were strengthened as
average common equity increased 10% or $246.6 million reaching a record $2.88
billion at year-end,
while total risk-weighted assets rose 5%. Total equity as of
December 31, 2002 was $3.0 billion, including $120 million of auction rate
preferred stock. The average dividend rate declared on the $120 million of
auction rate preferred stock, was 1.86% during 2002. During 2002, the
Corporation purchased 3,021,911 of its own shares as part of its buyback
program. The buyback program is designed, among other things, to help offset
the dilutive effect of the Corporation's incentive stock programs. The
Corporation may purchase up to 1.6 million additional shares after December 31,
2002.

                                    [GRAPHIC]

Management's Discussion and Analysis of
Financial Condition and Results of Operations


   The Board of Directors maintained the quarterly dividend at $.17 per common
share in November 2002. The common dividend has increased 62% from its level
five years ago.
   The higher capital levels in 2002 were the result of Northern Trust's
ongoing policy of retaining a sufficient percentage of earnings in the
Corporation to allow for strategic expansion while maintaining a strong balance
sheet. All of Northern Trust's capital ratios were well above the ratios that
are a requirement for regulatory treatment as "well capitalized." At December
31, 2002, tier 1 capital was 11.1% and total capital was 14.1% of risk-weighted
assets. These risk-based capital ratios are well above the minimum requirements
of 4.0% for tier 1 and 8.0% for total risk-based capital ratios. Northern
Trust's leverage ratio (tier 1 capital to fourth quarter average assets) of
7.8% is also well above the regulatory requirement of 3.0%. In addition, each
of the subsidiary banks had a ratio of at least 9.7% for tier 1 capital, 11.0%
for total risk-based capital, and 6.6% for the leverage ratio.

Operational and Fiduciary Risk Management
In providing banking and trust services, Northern Trust, in addition to
safekeeping and managing trust and corporate assets, processes cash and
securities transactions exceeding $180 billion on average each business day.
These activities expose Northern Trust to operational and fiduciary risk.
Controls over such processing activities are closely monitored to safeguard the
assets of Northern Trust and its clients. However, from time to time Northern
Trust has incurred losses related to these risks and there can be no assurance
that such losses will not occur in the future.
   Operational risk is the risk of unexpected losses attributable to human
error, systems failures, fraud, or inadequate internal controls and procedures.
This risk is mitigated through a system of internal controls that are designed
to keep operating risk at levels appropriate to Northern Trust's corporate
standards in view of the risks inherent in the markets in which Northern Trust
operates. The system of internal controls includes policies and procedures that
require the proper authorization, approval, documentation and monitoring of
transactions. Each business unit is responsible for complying with corporate
policies and external regulations applicable to the unit, and is responsible
for establishing specific procedures to do so. Northern Trust's internal
auditors monitor the overall effectiveness of the system of internal controls
on an ongoing basis.
   Fiduciary risk is the risk of loss that may occur as a result of breaching a
fiduciary duty to a client. To limit this risk, the Trust Investment Committee
establishes corporate policies and procedures to reduce the risk that
obligations to clients would not be discharged faithfully or in compliance with
applicable legal and regulatory requirements. These policies and procedures
provide guidance and establish standards related to the creation, sale, and
management of investment products, trade execution, and counterparty selection.
Business units have the primary responsibility for adhering to the policies and
procedures applicable to their businesses.

such as the discussion of Northern Trust's financial goals, dividend policy,
expansion and business development plans, business prospects and positioning
with respect to market and pricing trends, new business results and outlook,
changes in securities market prices, credit quality including reserve levels,
planned capital expenditures and technology spending, and the effect of
extraordinary events and various other matters (including changes in accounting

"will," "should," "would," and "could." Forward-looking statements are Northern
Trust's current estimates or expectations of future events or future results.
Actual results could differ materially from the results indicated by these
statements because the realization of those results is subject to many risks
and uncertainties including:

  .  The future health of the U.S. and international economies and other
     economic factors, including consumer confidence in the securities markets,
     that affect wealth creation, investment and savings patterns and Northern
     Trust's interest rate risk and credit risk exposure.
  .  Changes in U.S. and worldwide securities markets, with respect to the
     market values of financial assets, the stability of particular securities
     markets and the level of volatility in certain markets such as foreign
     exchange.
  .  U.S. and international economic factors that may impact Northern Trust's
     interest rate risk, including the level of or change in interest rate, and
     credit risk exposure.
  .  The effects of extraordinary events (such as terrorist events, war and the
     U.S. government's response to those events).
  .  Changes in the level of cross-border investing by clients resulting from
     changing economic factors, political conditions or currency markets.

                          62 NORTHERN TRUST CORPORATION



                                    [GRAPHIC]

                   Notes to Consolidated Financial Statements

1. Accounting Policies--The consolidated financial statements have been
prepared in conformity with generally
accepted accounting principles and reporting practices prescribed for the
banking industry. A description of the significant accounting policies follows:
   A. Basis of Presentation. The consolidated financial statements include the
accounts of Northern Trust Corporation (Corporation) and its wholly-owned
subsidiary The Northern Trust Company (Bank) and their wholly-owned
subsidiaries. Throughout the notes, the term "Northern Trust" refers to
Northern Trust Corporation and its subsidiaries. Intercompany balances and
transactions have been eliminated in consolidation. The consolidated statement
of income includes results of acquired subsidiaries from the dates of
acquisition.
   B. Nature of Operations. The Corporation is a bank holding company whose
principal subsidiary is the Chicago-based Bank. The Corporation also owns
national bank subsidiaries with offices in Arizona, California, Colorado,
Florida, and Texas, a federal savings bank with offices in Michigan, Missouri,
Nevada, Ohio, Washington and Wisconsin, a trust company in New York and various
other nonbank subsidiaries, including a securities brokerage firm, an
international investment consulting firm and a retirement services company. The
Bank has offices in the Chicago metropolitan area, global custody operations in
London and various subsidiaries, including an investment management company, a
leasing company, a Canadian trust company, a New York Edge Act company and a
global fund services provider. Northern Trust generates the majority of its
revenues from its two primary business units, Corporate and Institutional
Services (C&IS) and Personal Financial Services (PFS). Investment management
services and products are provided to C&IS and PFS through a third business
unit, Northern Trust Global Investments (NTGI). Operating and systems support
for these business units are provided by a fourth business unit, Worldwide
Operations and Technology (WWOT). Northern Trust has not utilized
unconsolidated special purpose entities to provide financing, improve
liquidity, transfer assets or manage credit risk.
   The C&IS business unit provides investment asset administration and related
services worldwide to corporate and public entity retirement funds, foundation
and endowment clients, fund managers, insurance companies and government funds;
a full range of commercial banking services to large domestic corporations and
financial institutions including treasury management; a comprehensive array of
retirement consulting, actuarial and recordkeeping services; and foreign
exchange services for global custody clients and Northern Trust's own account.
   The PFS business unit provides personal trust, custody and investment
management services, individual retirement accounts, guardianship, estate
administration, banking (including private banking) and residential real estate
mortgage lending services, and also provides commercial banking services to
small/mid-size businesses. These services are delivered through the Bank in
Illinois and the network of subsidiaries with offices in Arizona, California,
Colorado, Florida, Michigan, Missouri, Nevada, Ohio, Texas, Washington and
Wisconsin.
   C. Use of Estimates in the Preparation of Financial Statements. The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the consolidated financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
   D. Foreign Currency Translation. If the functional currency of a foreign
branch or subsidiary is the U.S. dollar, foreign currency asset and liability
accounts are translated at current rates of exchange, except for buildings and
equipment which are translated at rates in effect at the date of acquisition.
Results from remeasurement are reported in foreign exchange trading profits.
Income and expense accounts are translated at month-end rates of exchange.
   If the functional currency of a foreign branch or subsidiary is its local
currency, the local currency asset and liability accounts are translated at
current rates. Translation adjustments are reported, net of tax, directly to
accumulated other comprehensive income, a component of stockholders' equity.
Income and expense accounts are translated at month-end rates of exchange.
       E. Securities. Securities Available for Sale consist of debt and equity
securities that are not intended to be held to maturity and are not held for
trading. Securities available for sale are reported at fair value, with
unrealized gains and losses credited or charged, net of the tax effect, to
accumulated other comprehensive income, a component of stockholders' equity.
Realized gains and losses on securities available for sale are determined on a
specific identification basis and are reported in the consolidated statement of
income as investment security gains and losses. Interest income is recorded on
the accrual basis adjusted for amortization of premium and accretion of
discount.
   Securities Held to Maturity consist of debt securities that management
intends to, and Northern Trust has the ability to, hold until maturity. Such
securities are reported at cost, adjusted for amortization of premium and
accretion of

                   Notes to Consolidated Financial Statements

discount. Interest income is recorded on the accrual basis adjusted for
amortization of premium and accretion of discount.
   Securities Held for Trading are stated at fair value. Realized and
unrealized gains and losses on securities held for trading are reported in the
consolidated statement of income under security commissions and trading income.
   F. Derivative Financial Instruments. Northern Trust adopted Statement of
Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative
Instruments and Hedging Activities" and its related amendments on January 1,
2001. Derivative financial instruments include interest rate swap contracts,
futures contracts, forward foreign currency contracts, options and similar
contracts. Northern Trust is a party to various derivative instruments as part
of its asset/liability management activities, to meet the risk management needs
of its clients and as part of its trading activity for its own account.
Unrealized gains and receivables on derivative instruments are reported as
other assets and unrealized losses and payables are reported as other
liabilities in the consolidated balance sheet.
   Asset/Liability Management. Derivatives entered into for asset/liability
management purposes are designated and formally documented as fair value, cash
flow or net investment hedges on the date they are transacted. The formal
documentation describes the hedge relationship and identifies the hedging
instruments and hedged items. Included in the documentation is a discussion of
the risk management objectives and strategies for undertaking such hedges, as
well as a description of the method for assessing hedge effectiveness at
inception and on an ongoing basis. A formal assessment is performed on a
calendar quarter basis to determine that derivatives used in hedging
transactions are highly effective as offsets to changes in fair value or cash
flows of the hedged item. If a derivative ceases to be highly effective or if
hedged forecasted transactions are no longer expected to occur, hedge
accounting is terminated and the derivative is treated as if it were a
client-related or trading instrument.
   Fair value hedge designations are made between a derivative and a recognized
asset or liability. Interest accruals and changes in fair value of the
derivative are recognized as a component of the interest income or expense
classification of the hedged item. Changes in fair value of the hedged asset or
liability attributable to the risk being hedged are reflected in its carrying
amount and are also recognized as a component of its interest income or expense.
   Cash flow hedge designations are made between derivatives and forecasted
cash inflows or outflows so as to hedge against variability due to a specific
risk. The effective portion of unrealized gains and losses on such derivatives
is recognized in accumulated other comprehensive income, a component of
stockholders' equity. When the hedged forecasted transaction impacts earnings,
balances in other comprehensive income are reclassified to the same income or
expense classification as the hedged item. Any hedge ineffectiveness is
recognized in the income or expense classification of the hedged item.
   Net investment hedge designations are made between a forward foreign
currency contract and a net investment in a foreign branch or subsidiary.
Changes in the fair value of the hedging contract are recognized in the foreign
exchange translation gain or loss account of stockholders' equity. Hedge
ineffectiveness is calculated based on changes in forward rates of the
derivative and the hedged net investment. Any ineffectiveness is recorded to
other income only if the notional amount of the derivative does not match the
portion of the net investment designated as being hedged.
   Other derivatives transacted as economic hedges of foreign denominated
assets and liabilities are carried on the balance sheet at fair value and
recognized currently in foreign exchange trading profits. Unrealized gains are
shown as other assets, with unrealized losses reported as other liabilities.
   Client-Related and Trading Instruments. Derivative financial instruments
entered into to meet clients' risk management needs or for trading purposes are
carried at fair value, with realized and unrealized gains and losses included
in security commissions and trading income or foreign exchange trading profits.
   G. Loans and Leases. Loans that are held to maturity are reported at the
principal amount outstanding, net of unearned income. Residential real estate
loans classified as held for sale are reported at the lower of aggregate cost
or market value. Loan commitments for residential real estate loans which will
be classified as held for sale at the time of funding and which have an
interest-rate lock, are recorded on the balance sheet at fair value with
associated gains or losses recognized as other income. Unrealized gains are
reported as other assets, with unrealized losses reported as other liabilities.
Other unfunded loan commitments that are not held for sale are carried at the
amount of unamortized fees with a reserve for credit loss liability recognized
for any probable losses.
   Interest income on loans is recorded on an accrual basis until, in the
opinion of management, there is a question as to the ability of the debtor to
meet the terms of the contract, or when interest or principal is more than 90
days past due and the loan is not well-secured and in the process of
collection. At the time a loan is placed on nonaccrual status, interest accrued
but not collected is reversed against interest income of the current period.
Loans are returned to accrual status when factors indicating doubtful
collectibility no longer exist. Interest col-

                   Notes to Consolidated Financial Statements

lected on nonaccrual loans is applied to principal unless, in the opinion of
management, collectibility of principal is not in doubt.
   Premiums and discounts on loans are recognized as an adjustment of yield
using the interest method based on the contractual terms of the loan.
Commitment fees that are considered to be an adjustment to the loan yield, loan
origination fees and certain direct costs are deferred and accounted for as an
adjustment to the yield.
   Unearned lease income from direct financing and leveraged leases is
recognized using the interest method. This method provides a constant rate of
return on the unrecovered investment over the life of the lease.
       H. Reserve for Credit Losses. The reserve for credit losses represents
management's estimate of probable inherent losses, which have occurred as of
the date of the financial statements. The loan and lease portfolio and other
credit exposures are regularly reviewed to evaluate the adequacy of the reserve
for credit losses. In determining the level of the reserve, Northern Trust
evaluates the reserve necessary for specific nonperforming loans and also
estimates losses inherent in other credit exposures. The result is a reserve
with the following components:
   Specific Reserve. The amount of specific reserves is determined through a
loan-by-loan analysis of nonperforming loans that considers expected future
cash flows, the value of collateral and other factors that may impact the
borrower's ability to pay.
   Allocated Inherent Reserve. The amount of the allocated portion of the
inherent loss reserve is based on loss factors assigned to Northern Trust's
credit exposures based on internal credit ratings. These loss factors are
primarily based on management's judgment of estimated credit losses inherent in
the loan portfolio as well as historical charge-off experience.
   Unallocated Inherent Reserve. Management determines the unallocated portion
of the inherent loss reserve based on factors that cannot be associated with a
specific credit or loan category. These factors include management's subjective
evaluation of local and national economic and business conditions, portfolio
concentration and changes in the character and size of the loan portfolio. The
unallocated portion of the reserve for credit losses reflects management's
attempt to ensure that the overall reserve appropriately reflects a margin for
the imprecision necessarily inherent in estimates of expected credit losses.
   Loans, leases and other extensions of credit deemed uncollectible are
charged to the reserve. Subsequent recoveries, if any, are credited to the
reserve. Actual losses may vary from current estimates and the amount of the
provision may be either greater than or less than actual net charge-offs.
The related provision for credit losses, which is charged to income, is the
amount necessary to adjust the reserve to the level determined through the
above process.
       The control process maintained by Credit Policy and the lending staff,
and the quarterly analysis of specific and inherent loss components are the
principal methods relied upon by management to ensure that changes in estimated
credit loss levels are adjusted on a timely basis. In addition to Northern
Trust's own experience, management also considers the experience of peer
institutions and regulatory guidance.
   Although Northern Trust analyzes its exposure to credit losses from both on-
and off-balance sheet activity as one process, during 2002 it began to record
the portion of the reserve assigned to unfunded commitments, standby letters of
credit and derivatives in other liabilities for financial reporting purposes.
The portion of the reserve assigned to loans and leases continues to be
reported as a contra asset, directly following loans and leases in the
Consolidated Balance Sheet.
   I. Fees on Standby Letters of Credit and Bankers Acceptances. Fees on
standby letters of credit are recognized in other operating income on the
straight-line method over the lives of the underlying agreements. Income from
commissions on bankers acceptances is recognized in other operating income when
the payment from the customer is received by the accepting bank.
   J. Buildings and Equipment. Buildings and equipment owned are carried at
original cost less accumulated depreciation. The charge for depreciation is
computed on the straight-line method based on the following range of lives:
buildings--10 to 30 years; equipment--3 to 10 years; and leasehold
improvements--lease term to 15 years. Leased properties meeting certain
criteria are capitalized and amortized using the straight-line method over the
lease period.
   K. Other Real Estate Owned (OREO). OREO is comprised of commercial and
residential real estate properties acquired in partial or total satisfaction of
problem loans. OREO assets are carried at the lower of cost or fair value.
Losses identified at the time of acquisition of such properties are charged
against the reserve for credit losses assigned to loans. Subsequent write-downs
that may be required to the carrying value of these assets and losses realized
from asset sales are charged to other operating expenses.
   L. Unconsolidated Affiliates. Northern Trust's 20% interest in RemitStream
Solutions, LLC (lockbox services), its interest in EquiLend LLC (securities
lending services) and its 50% interest in Helaba Northern Trust GMBH
(investment management services) are carried on the equity method of
accounting. The combined book value of these investments at December 31, 2002
totaled $3.9 million.

                   Notes to Consolidated Financial Statements

Northern Trust's $4.9 million investment in CLS Group Holdings (foreign
exchange settlement services) is carried at cost.
   M. Intangible Assets. SFAS No. 142 supercedes APB Opinion No. 17,
"Intangible Assets" and addresses the accounting for goodwill and other
intangible assets. As required, Northern Trust applied the provisions of this
Statement effective January 1, 2002 to all goodwill and other intangible assets
reflected in the consolidated financial statements at that date.
   Goodwill. The Statement discontinues amortization of goodwill over its
estimated useful life and requires a transitional impairment test of goodwill
as of January 1, 2002. An annual impairment test of goodwill is also required
in the year of adoption and in subsequent years. Impairment losses for goodwill
that arise due to the initial application of this Statement, resulting from the
transitional impairment test, are to be reported as a change in accounting
principle and any subsequent impairment losses are required to be reported as
operating expenses. Management completed the initial goodwill impairment test
as of January 1, 2002 and the annual test as of October 31, 2002 and determined
that no impairment charges were necessary. Goodwill at both December 31, 2001
and December 31, 2002 totaled $90.1 million. Prior to adoption of this
Statement, goodwill had been amortized on the straight-line method primarily
over fifteen years. Application of the nonamortization provisions of the
Statement reduced noninterest expense by approximately $10.0 million annually,
resulting in an increase in net income of $8.0 million in 2002 compared to 2001.
   Intangible Assets Subject to Amortization. Other separately identifiable
acquired intangible assets will continue to be amortized over their estimated
useful lives. At December 31, 2002, acquired intangible assets had a book value
of $28.5 million, which was net of accumulated amortization on these assets of
$59.2 million. Amortization for the year 2002 amounted to $6.6 million.
Amortization for the years ending 2003, 2004, 2005, 2006 and 2007 is estimated
to be $6.6 million, $6.6 million, $5.5 million, $5.1 million and $2.9 million,
respectively.
   Purchased software and other allowable internal costs, including
compensation, relating to software developed for internal use are capitalized.
Software is being amortized using the straight-line method over the estimated
useful life of the asset, ranging from 3 to 10 years.
   N. Trust Assets and Fees. Assets held in fiduciary or agency capacities are
not included in the consolidated balance sheet, since such items are not assets
of Northern Trust.
   Fees from trust activities are recorded on the accrual basis, over the
period in which the service is provided. Fees are a function of the market
value of assets managed and administered, the volume of transactions,
securities lending volume and spreads, and fees for other services rendered, as
set forth in the underlying client agreement. This revenue recognition involves
the use of estimates and assumptions, including components that are calculated
based on estimated asset valuations and transaction volumes.
   Certain investment management fee arrangements also may provide performance
fees which are based on client portfolio returns exceeding predetermined
levels. Northern Trust adheres to a policy in which it does not record any
performance-based fee income until the end of the contract year, thereby
eliminating the potential that revenue will be recognized in one quarter and
reversed in a future quarter. Therefore, Northern Trust does not record any
revenue under incentive fee programs that is at risk due to future performance
contingencies. These arrangements often contain similar terms for the payment
of performance-based fees to sub-advisors. The accounting for these
performance-based expenses matches the treatment for the related
performance-based revenues.
   Client reimbursed out-of-pocket expenses on occasion, involve trust
activities. Where such reimbursements are an extension of the trust service
rendered, they are recorded on a gross basis as trust revenue.
   O. Trust Security Settlement Receivables. These receivables represent other
items in the process of collection presented on behalf of trust clients.
   P. Income Taxes. In accordance with SFAS No. 109, "Accounting for Income
Taxes," Northern Trust follows an asset and liability approach to account for
income taxes. The objective is to recognize the amount of taxes payable or
refundable for the current year, and to recognize deferred tax assets and
liabilities resulting from temporary differences between the amounts reported
in the financial statements and the tax bases of assets and liabilities. The
measurement of tax assets and liabilities is based on enacted tax laws and
applicable tax rates.
   Q. Cash Flow Statements. Cash and cash equivalents have been defined as
"Cash and Due from Banks."
   R. Stock-Based Compensation Plans. Statement of Financial Accounting
Standards No. 123, "Accounting for Stock-Based Compensation," establishes
financial accounting and reporting standards for stock-based compensation plans.
   SFAS No. 123 allows two alternative accounting methods: (1) a
fair-value-based method, or (2) an intrinsic-value-based method which is
prescribed by Accounting Principles Board Opinion No. 25, "Accounting for Stock
Issued to Employees" (APB No. 25) and related interpretations. Northern Trust
has elected to account for its stock-based incentive plans and awards under APB
No. 25, and has adopted the disclosure requirements of SFAS No. 123 which have
been amended by

                   Notes to Consolidated Financial Statements

SFAS No. 148, "Accounting for Stock-Based Compensation-Transition and
Disclosure."
   Pro forma information regarding net income and earnings per share is
required by SFAS No. 123, and has been determined as if the Corporation had
accounted for its stock-based compensation under SFAS No. 123. For purposes of
estimating the fair value of the Corporation's employee stock options at the
grant-date, a Black-Scholes option pricing model was used with the following
weighted average assumptions for 2002, 2001 and 2000, respectively: risk-free
interest rates of 5.11%, 5.36% and 6.41%; dividend yields of 1.29%, 1.00% and
..88%; volatility factors of the expected market price of the Corporation's
common stock of 31.2%, 30.0% and 30.0%; and a weighted average expected life of
the options of 6.2 years, 5.9 years and 5.4 years.
   The weighted average fair value of options granted in 2002, 2001 and 2000
was $18.75, $24.30 and $25.92, respectively. For purposes of pro forma
disclosures, the estimated fair value of the options is amortized to expense
over the options' six months to three-year vesting periods.
   The Corporation's pro forma information follows:

2. Reclassifications--In 2002, Northern Trust adopted Emerging Issues Task
Force (EITF) 01-14, "Income Statement Characterization of Reimbursements
Received for 'Out-of-Pocket' Expenses Incurred," which requires that
client-reimbursed out-of-pocket expenses be recorded as gross revenue and
expense. These reimbursements were previously reported as a reduction of
expense. This change, which has no impact on net income, increased trust fees,
treasury management and other revenues with an offsetting increase in other
operating expenses. Prior period amounts have been reclassified.
   Other reclassifications have been made to prior periods' consolidated
financial statements to place them on a basis comparable with the current
period's consolidated financial statements.

any potential credit risk associated with these transactions, the fair value of
the securities purchased or sold is continuously monitored, limits are set on
exposure with counterparties, and the financial condition of counterparties is
regularly assessed. It is Northern Trust's policy to take possession of
securities purchased under agreements to resell.

event of sale or refinancing, the Bank will receive all proceeds except for 58%
of any proceeds in excess of the original project costs, which will be paid to
the lessor.
   The following table reflects the future minimum lease payments required
under capital leases, net of any payments received on the long-term financing,

             Total Debt-Floating Rate Capital
              Securities............................. $267.8 $267.7


   In January 1997, the Corporation issued $150 million of Floating Rate
Capital Securities, Series A, through a statutory business trust wholly-owned
by the Corporation ("NTC Capital I"). In April 1997, the Corporation also
issued, through a separate wholly-owned statutory business trust ("NTC Capital
II"), $120 million of Floating Rate Capital Securities, Series B. The sole
assets of the trusts are Subordinated Debentures of Northern Trust Corporation
that have the same interest rates and maturity dates as the corresponding
distribution rates and redemption dates of the Floating Rate Capital
Securities. The outstanding principal amounts of the Subordinated Debentures
held by NTC Capital I and NTC Capital II are $154.6 million and $123.7 million,
respectively. The Series A Securities were issued at a discount to yield 60.5
basis points above the three-month London Interbank Offered Rate (LIBOR), while
the Series B Securities were issued at a discount to yield 67.9 basis points
above the three-month LIBOR. Both Series A and B Securities qualify as tier 1
capital for regulatory purposes.
   The Corporation has fully, irrevocably and unconditionally guaranteed all
payments due on such Capital Securities. The holders of the Capital Securities
are entitled to receive preferential cumulative cash distributions quarterly in
arrears (based on the liquidation amount of $1,000 per Capital Security) at an
interest rate equal to the rate on the corresponding Subordinated Debentures.
The interest rate on the Series A and Series B securities is equal to
three-month LIBOR plus 0.52% and 0.59%, respectively. Subject to certain
exceptions, the Corporation has the right to defer payment of interest on the
Subordinated Debentures at any time or from time to time for a period not
exceeding 20 consecutive quarterly periods provided that no extension period
may extend beyond the stated maturity date. If interest is deferred on the
Subordinated Debentures, distributions on the Capital Securities will also be
deferred and the Corporation will not be permitted, subject to certain
exceptions, to pay or declare any cash distributions with respect to the
Corporation's capital stock or debt securities that rank the same as or junior
to the Subordinated Debentures, until all past due distributions are paid. The
Subordinated Debentures are unsecured and subordinated to substantially all of
the Corporation's existing indebtedness.
   The Corporation has the right to redeem the Series A Subordinated Debentures
on or after January 15, 2007 and the Series B Subordinated Debentures on or
after April 15, 2007, in each case in whole or in part. In addition, the
Corporation has the right to redeem the Subordinated Debentures held by either
trust in whole but not in part at any time within 90 days following certain
defined tax or regulatory capital treatment changes, at a price equal to the
principal amount plus accrued and unpaid interest.

11. Stockholders' Equity--Preferred Stock. The Corporation is authorized to
issue 10,000,000 shares of preferred stock without par value. The Board of
Directors of the Corporation is authorized to fix the particular preferences,
rights, qualifications and restrictions for each series of preferred stock
issued. A summary of preferred stock outstanding is presented below.

Series C--In 1987, 600 shares of Auction Rate Preferred Stock Series C (APS)
were issued, with a $100,000 per share stated value. Dividends on the shares of
APS are cumulative. Rates are determined every 49 days by Dutch auction unless
the Corporation fails to pay a dividend or redeem any shares for which it has
given notice of redemption, in which case the dividend rate will be set at 175%
of the 60-day "AA" Composite Commercial Paper Rate. The dividend rate in any
auction will not exceed a percentage determined by the prevailing credit rating
of the APS. The current maximum dividend rate is 120% of the 60-day "AA"
Composite Commercial Paper Rate. No dividends other than dividends payable in
junior stock, such as common stock, may be paid on common stock until full
cumulative dividends on the APS have been paid. The average rate for this issue
as declared during 2002 was 1.84%. The shares of APS are redeemable at the
option of the Corporation, in whole or in part, on any Dividend Payment Date at
$100,000 per share, plus accrued and unpaid dividends.

Series D--In 1990, 600 shares of Flexible Auction Rate Cumulative Preferred
Stock Series D (FAPS) were issued with a $100,000 per share stated value. Each
dividend period contains 49 days (the "Short-Term Dividend Period") or a number
of days greater than 49 days (as selected by the Term Selection Agent) which is
divisible by seven (the "Long-Term Dividend Period"). Rates for each dividend
period are determined by Dutch auction unless the Corporation fails to pay the
full amount of any dividend or redemption. The dividend rate in any auction
will not exceed a percentage (currently 125%), determined by the prevailing
credit rating of the FAPS, of the 60-day "AA" Composite Commercial Paper Rate
or the Reference Rate, which rate is the Composite Commercial Paper Rate or the
Treasury Rate, as appropriate for the length of each Short-Term or Long-Term
Dividend Period, respectively. If the Corporation fails to pay the full amount
of any dividend or redemption, each dividend period thereafter (until auctions
are resumed) will be a Short-Term Dividend Period and the dividend rate will be
250% of the 60-day "AA" Composite Commercial Paper Rate; additional dividends
will accrue for the balance of any Long-Term Dividend Period in which such a
failure to pay occurs. No dividends other than dividends payable in junior
stock, such as common stock, may be paid on common stock until full cumulative
dividends on the FAPS have been paid. The average rate for this issue as
declared during 2002 was 1.88%. The shares of FAPS are redeemable at the option
of the Corporation, in whole or in part, at $100,000 per share plus accrued and
unpaid dividends.

Preferred Stock Purchase Rights--On July 21, 1998 the Board of Directors of the
Corporation declared a dividend distribution of one Preferred Stock Purchase
Right for each outstanding share of the Corporation's common stock issuable to
stockholders of record at the close of business on October 31, 1999. As a
result of anti-dilution provisions, each share of common stock now has one-half
of one Right associated with it. Each Right is exercisable for one
one-hundredth of a share of Series A Junior Participating Preferred Stock at an
exercise price of $330.00, subject to adjustment. The Rights will be evidenced
by the common stock certificates and will not be exercisable or transferable
apart from the common stock until twenty days after a person or group acquires
15 percent or more of the shares of common stock then outstanding or announces
a tender or exchange offer which if consummated would result in ownership of 15
percent or more of the outstanding common stock.
   In the event that any person or group acquires 15 percent or more of the
outstanding shares of common stock, each Right entitles the holder, other than
such person or group, to purchase that number of shares of common stock of the
Corporation having a market value of twice the exercise price of the Right. At
any time thereafter if the Corporation consummates a business combination
transaction or sells substantially all of its assets, each Right entitles the
holder, other than the person or group acquiring 15 percent or more of the
outstanding shares of common stock, to purchase that number of shares of
surviving company stock which at the time of the transaction would have a
market value of twice the exercise price of the Right.
   The Rights do not have voting rights and are redeemable at the option of the
Corporation at a price of one-half of one cent per Right at any time prior to
the close of business on the twentieth day following announcement by the
Corporation of the acquisition of 15 percent or more of the outstanding common
stock by a person or group. Unless earlier redeemed, the Rights will expire on
October 31, 2009.

December 31, 2002 and 2001 as management believes it is more likely than not
that the deferred tax assets will be fully realized.
   At December 31, 2002, Northern Trust had federal net operating loss
carryforwards of $.5 million resulting from the acquisition of businesses that
had existing net operating loss carryforwards. These carryforwards are
available to reduce future tax return liabilities and if not used, will begin
to expire in 2011. In addition, Northern Trust had state net operating loss and
tax credit carryforwards of $496.3 million and $.6 million, respectively. State
net operating loss carryforwards of $3.3 million will expire in 2005, $2.9
million in 2006 and the remainder from 2018 through 2021. The state tax credits
will expire in 2003 through 2007. The carryforwards are subject to various
limitations imposed by tax laws.

15. Restrictions on Subsidiary Dividends and Loans or Advances--Provisions of
state and federal banking laws restrict the amount of dividends that can be
paid to the Corporation by its banking subsidiaries. Under applicable state and
federal laws, no dividends may be paid in an amount greater than the net
profits then on hand, subject to other applicable provisions of law. In
addition, prior approval from the relevant federal banking regulator is
required if dividends declared by any of the Corporation's banking subsidiaries
in any calendar year will exceed its net profits (as defined) for that year,
combined with its retained net profits for the preceding two years. Based on
these regulations, the Corporation's banking subsidiaries, without regulatory
approval, could declare dividends during 2003 equal to their 2003 eligible net
profits (as defined) plus $378.9 million. The ability of each banking
subsidiary to pay dividends to the Corporation may be further restricted as a
result of regulatory policies and guidelines relating to dividend payments and
capital adequacy.
   State and federal laws limit the transfer of funds by a banking subsidiary
to the Corporation and certain of its affiliates in the form of loans or
extensions of credit, investments or purchases of assets. Transfers of this
kind to the Corporation or a nonbanking subsidiary by a banking subsidiary are
each limited to 10% of the banking subsidiary's capital and surplus with
respect to each affiliate and to 20% in the aggregate, and are also subject to
certain collateral requirements. These transactions, as well as other
transactions between a banking subsidiary and the Corporation or its
affiliates, must also be on terms substantially the same as, or at least as
favorable as, those prevailing at the time for comparable transactions with
non-affiliated companies or, in the absence of comparable transactions, on
terms, or under circumstances, including credit standards, that would be
offered to, or would apply to, non-affiliated companies.

16. Other Operating Income--Other operating income in 2002 included gains of
$8.5 million from the sale of leased equipment at the end of the scheduled
lease terms. Other operating income in 2002 was reduced by a $15.0 million
write-off of an equity investment in myCFO, Inc., a $4.8 million write-off of
an equity investment in Global Straight Through Processing Association and a
$4.6 million write-off of the residual value of an aircraft leased to United
Airlines. In 2001 and 2000, nonrecurring gains totaled $9.2 million and $4.5
million, respectively.

   Software, goodwill and other intangible assets are included in other assets
in the consolidated balance sheet. Software totaled $371.1 million at December
31, 2002 and $329.8 million at December 31, 2001. Goodwill totaled $90.1
million at both December 31, 2002 and December 31, 2001. Other intangibles
totaled $28.5 million at December 31, 2002 and $35.2 million at December 31,
2001.

19. Employee Benefits--Pension. A noncontributory qualified pension plan covers
substantially all employees. Assets held by the plan consist primarily of
listed stocks and corporate bonds.
   Effective January 1, 2002, the pension formula was changed from a
traditional final average pay formula to what is generally known as a pension
equity formula. All employees hired on or after June 1, 2001 are required to
have their pension computed under the pension equity formula. All employees
hired before June 1, 2001 (and continually active throughout 2001) were
entitled to a one-time pension election to either remain with the traditional
pension plan formula or change to the new pension equity formula for accruals
after December 31, 2001. Although these changes are expected to reduce the
long-term cost of the plan, for the next several years it is estimated that the
plan change will increase the annual service cost by approximately $.5 million.
   Northern Trust also maintains a noncontributory nonqualified pension plan
for participants whose retirement benefit payments under the qualified plan are
expected to exceed the limits imposed by federal tax law. Northern Trust has a
nonqualified trust, referred to as a "Rabbi" Trust, to fund benefits in excess
of those permitted in certain of its qualified plans. The primary purpose of
the trust is to fund nonqualified retirement benefits. This arrangement offers
participants a degree of assurance for payment of benefits in excess of those
permitted in the related qualified plans. The assets remain subject to the
claims of creditors and are not the property of the employees. Therefore, they
are accounted for as corporate assets and are included in other assets in the
consolidated balance sheet.

matching contribution is contingent upon meeting a predefined earnings target
for the year. In 2002, 2001 and 2000, the corporate contribution equaled
approximately 4% of an employee's salary. The estimated contribution to this
plan is charged to employee benefits and totaled $16.3 million in 2002, $15.0
million in 2001 and $13.5 million in 2000.

Employee Stock Ownership Plan (ESOP). A leveraged ESOP in which substantially
all employees of Northern Trust are eligible to participate was established in
1989. All of the original 18 million shares in the ESOP Trust have been
allocated and all ESOP-related debt had been repaid as of December 31, 2001. In
2002, the corporate contribution to the ESOP was equal to 2% of an employee's
salary. Beginning in 2003, the corporate contribution will be equal to 1% of an
employee's salary. This amount can be increased by up to an additional 3% if
corporate performance exceeds a predetermined earnings target.
   The following table presents information related to the ESOP as well as
similar plans.

Other Postretirement Benefits. Northern Trust maintains an unfunded
postretirement health care plan. Employees retiring at age 55 or older under
the provisions of The Northern Trust Company Pension Plan who have attained 15
years of service are eligible for postretirement health care coverage. For
retirees under age 65, these benefits are provided through an indemnity plan,
subject to deductibles, co-payment provisions and other limitations, through
health maintenance organizations or through a catastrophic health plan. For
retirees over age 65, benefits are provided through various Medigap option
plans, a prescription drug plan or through a health maintenance organization.
Effective January 1, 2003, the cost of this benefit will not be subsidized by
Northern Trust for new employee hires or employees who are under age 40 at
December 31, 2002. However, these individuals, as well as employees who
terminate at 55 or older with 5-14 years of service, will have access to
certain retiree medical plan options. This plan change reduced the
postretirement benefit obligation by $1.5 million at December 31, 2002. The
provisions of this plan may be changed further at the discretion of Northern
Trust, which also reserves the right to terminate these benefits at any time.
   The following tables set forth the plan status at
December 31 and the net periodic postretirement benefit cost of the domestic
postretirement health care plan for 2002 and 2001. The transition obligation at
January 1, 1993 is being amortized to expense over a twenty-year period.

   Postretirement health care expense for 2000 was $3.8 million.
   The weighted average discount rate used in determining the accumulated
postretirement benefit obligation was 6.75% at December 31, 2002 and 7.5% at
December 31, 2001. For measurement purposes, an 8.5% annual increase in the
cost of covered health care benefits was assumed for 2003. This rate is assumed
to decrease to 5.5% in 2005 and remain at that level thereafter. The health
care cost trend rate assumption has an effect on the amounts reported. For
example, increasing or decreasing the assumed health care trend rate by one
percentage point in each year would have the following effect.

                   Notes to Consolidated Financial Statements


20. Contingent Liabilities--Because of the nature of its activities, Northern
Trust is subject to pending and threatened legal actions that arise in the
normal course of business. Management cannot estimate the specific possible
loss or range of loss that may result from these proceedings since it is not
possible to formulate a meaningful opinion as to the range of possible outcomes
and plaintiffs' ultimate damage claims. In the judgment of management, after
consultation with legal counsel, none of the Corporation's litigation to which
the Corporation or any of its subsidiaries is a party, including the matters
described below, will have a material effect, either individually or in the
aggregate, on the Corporation's consolidated financial position or results of
operations.
   One subsidiary of the Corporation has been named as a defendant in several
Enron-related class action suits that have been consolidated under a single
complaint in the Federal District Court for the Southern District of Texas
(Houston). Individual participants in the employee pension benefit plans
sponsored by Enron Corp. sued various corporate entities and individuals,
including the Bank, in its capacity as the former trustee of the Enron Corp.
Savings Plan and former service-provider for the Enron Corp. Employee Stock
Ownership Plan. The actions make claims, inter alia, for breach of fiduciary
duty to the plan participants, and seek equitable relief and monetary damages
in an unspecified amount against the defendants. The Corporation and the Bank
intend to defend these actions vigorously. In addition, the U.S. Department of
Labor is conducting an investigation of the individuals and entities connected
with Enron Corp.'s ERISA plans, including, as to the Corporation, the Bank and
Northern Trust Retirement Consulting, L.L.C. Based upon the information
developed to date and recognizing that the outcome of complex litigation and
related matters is uncertain, management believes these matters will be
resolved without material impact on the Corporation's consolidated financial
position or results of operations.

21. Off-Balance Sheet and Derivative Financial Instruments--Commitments and
Letters of Credit. Northern Trust, in the normal course of business, enters
into various types of commitments and issues letters of credit to meet the
liquidity and credit enhancement needs of its clients. Credit risk is the
principal risk associated with these instruments. The contractual amounts of
these instruments represent the credit risk should the instrument be fully
drawn upon and the client defaults. To control the credit risk associated with
entering into commitments and issuing letters of credit, Northern Trust
subjects such activities to the same credit quality and monitoring controls as
its lending activities.
       Commitments and letters of credit consist of the following:
       Legally Binding Commitments to Extend Credit generally have fixed
expiration dates or other termination clauses. Since a significant portion of
the commitments are expected to expire without being drawn upon, the total
commitment amount does not necessarily represent future loans or liquidity
requirements.
       Bankers Acceptances obligate Northern Trust, in the event of default by
the counterparty, to reimburse the holder of the acceptance.
       Commercial Letters of Credit are instruments issued by Northern Trust on
behalf of its clients that authorize a third party (the beneficiary) to draw
drafts up to a stipulated amount under the specified terms and conditions of
the agreement. Commercial letters of credit are issued primarily to facilitate
international trade.
       Standby Letters of Credit obligate Northern Trust to meet certain
financial obligations of its clients, if, under the contractual terms of the
agreement, the clients are unable to do so. These instruments are primarily
issued to support public and private financial commitments, including
commercial paper, bond financing, initial margin requirements on futures
exchanges and similar transactions. Certain standby letters of credit have been
secured with cash deposits or participated to others. Northern Trust is
obligated to meet the entire financial obligation of these agreements and in
certain cases is able to recover the amounts paid through recourse against cash
deposits or other participants.
       The following table shows the contractual amounts of commitments and
letters of credit.

                   Notes to Consolidated Financial Statements


Derivative Financial Instruments. These instruments include foreign exchange
contracts, foreign currency and interest rate futures contracts, and various
interest risk management instruments.
   Northern Trust is a party to various derivative financial instruments that
are used in the normal course of business to meet the risk management needs of
its clients; as part of its trading activity for its own account; and as part
of its asset/liability management activities. The major risk associated with
these instruments is that interest or foreign exchange rates could change in an
unanticipated manner, resulting in higher interest costs or a loss in the
underlying value of the instrument. These risks are mitigated by establishing
limits for risk management positions, monitoring the level of actual positions
taken against such established limits, monitoring the level of any interest
rate sensitivity gaps created by such positions, and by using hedging
techniques. When establishing position limits, market liquidity and volatility,
as well as experience in each market, are all taken into account.
   The estimated credit risk associated with these instruments relates to the
failure of the counterparty to pay based on the contractual terms of the
agreement, and is generally limited to the gross unrealized market value gains
on these instruments. The amount of credit risk will increase or decrease
during the lives of the instruments as interest or foreign exchange rates
fluctuate. This risk is controlled by limiting such activity to an approved
list of counterparties and by subjecting such activity to the same credit and
quality controls as are followed in lending and investment activities.
   Risk management instruments include:
   Foreign Exchange Contracts are agreements to exchange specific amounts of
currencies at a future date, at a specified rate of exchange. Foreign exchange
contracts are entered into primarily to meet the foreign exchange risk
management needs of clients. Foreign exchange contracts are also used for
trading purposes and asset/liability management.
   Foreign Currency and Interest Rate Futures Contracts are agreements for
delayed delivery of foreign currency, securities or money market instruments in
which the buyer agrees to take delivery at a specified future date of a
specified currency, security, or instrument, at a specified price or yield. All
of Northern Trust's futures contracts are traded on organized exchanges that
require the daily settlement of changes in the value of the contracts. Futures
contracts are utilized in trading activities and asset/ liability management to
limit Northern Trust's exposure to unfavorable fluctuations in foreign exchange
rates or interest rates.
   Interest Rate Protection Contracts are agreements that enable clients to
transfer, modify or reduce their interest rate risk. As a seller of interest
rate protection, Northern Trust receives a fee at the outset of the agreement
and then assumes the risk of an unfavorable change in interest rates. Northern
Trust also purchases interest rate protection contracts for asset/liability
management.
   Interest Rate Swap Contracts involve the exchange of fixed and floating rate
interest payment obligations without the exchange of the underlying principal
amounts.
   Forward Sale Contracts represent commitments to sell a specified amount of
securities at an agreed upon date and price. Northern Trust utilizes forward
sale contracts principally in connection with its sale of mortgage loans.
   Exchange-Traded Option Contracts grant the buyer the right, but not the
obligation, to purchase or sell at a specified price, a stated number of units
of an underlying financial instrument, at a future date.
   The following table shows the contractual/notional amounts of risk
management instruments. The notional amounts of risk management instruments do
not represent credit risk, and are not recorded in the consolidated balance
sheet. They are used merely to express the volume of this activity. Credit risk
is limited to the positive market value of the derivative financial instrument,
which is significantly less than the notional amount, and is shown as the asset
amounts in the Fair Value of Off-Balance Sheet and Derivative Financial
Instruments table on page 83.

                   Notes to Consolidated Financial Statements


Derivative Financial Instruments Used for Asset/ Liability Management. Northern
Trust adopted SFAS No. 133 and its related amendments on January 1, 2001. In
reviewing the accounting requirements of these statements, Northern Trust
concluded that certain hedge strategies previously used to manage fixed
interest rate risk would not qualify for special hedge accounting treatment.
Management implemented alternative strategies for managing interest rate risk
that included the termination and run-off of certain interest rate swap
contracts used to hedge fixed rate loans and increased utilization of
longer-term fixed rate liabilities. The cumulative effect of adopting these
statements increased earnings by less than $10 thousand and reduced other
comprehensive income by $.2 million.
   Deferred gains and losses on derivative financial instruments used for
asset/liability management purposes prior to adoption of SFAS No. 133 and
included in the consolidated balance sheet at year-end 2002 totaled $10.3
million and $1.4 million, respectively. Deferred gains and losses at year-end
2001 totaled $14.7 million and $3.4 million, respectively.
   Fair Value Hedge Designations. Northern Trust may designate certain
derivatives as hedges of specific fixed rate assets or liabilities on its
balance sheet. The risk management policy for such hedges is to reduce or
eliminate the exposure to changes in the value of the hedged assets or
liabilities due to a specified risk. As of December 31, 2002, certain interest
rate swaps were designated and qualified as a hedge against changes in LIBOR
interest rates for specific fixed rate agency and asset-backed securities.
There was no hedge ineffectiveness through December 31, 2002.
   Cash Flow Hedge Designations. Certain derivatives may be designated as
hedges against exposure to variability in expected future cash flows
attributable to particular risks, such as fluctuations in foreign exchange or
interest rates. Northern Trust currently uses cash flow hedges to reduce or
eliminate the exposure to changes in foreign exchange and LIBOR interest rates.
As of December 31, 2002, certain forward foreign exchange contracts were
designated and qualified as hedges against changes in certain forecasted
transactions denominated in foreign currencies. It is estimated that a net gain
of $3.6 million will be reclassified into earnings within the next 12 months.
The maximum length of time over which these hedges will exist is 13 months.
Hedge ineffectiveness was negligible through December 31, 2002.
   As of December 31, 2002, interest rate swaps were designated and qualified
as hedges against variability in interest cash flows due to changes in LIBOR
interest rates for specific time deposits with banks. It is estimated that $2.4
million of net gains associated with these hedges will be reclassified into
earnings within the next 12 months. The maximum length of time over which these
hedges will exist is approximately 12 months. There was no hedge
ineffectiveness through December 31, 2002.
   Net Investment Hedge Designations. Northern Trust has designated specific
forward foreign currency contracts as hedges against foreign currency exposure
for net investments in foreign affiliates. For the year ended December 31,
2002, a net loss of $.8 million was recorded within foreign currency
translation adjustments, a component of capital.
   Other Derivatives not Designated as Hedges. Forward foreign exchange
contracts were used to reduce exposure to fluctuations in the dollar value of
capital investments in foreign subsidiaries and from foreign currency assets
and obligations. Realized and unrealized gains and losses on such contracts are
recognized as a component of foreign exchange trading profits.

Client and Trading-Related Derivative Financial Instruments. Net revenue
associated with client and trading-related interest rate derivative financial
instruments totaled $.1 million, $.2 million, and $.7 million during 2002,
2001, and 2000, respectively. The majority of these revenues are related to
interest rate swaps and interest rate protection agreements.

Other Off-Balance Sheet Financial Instruments. As part of securities custody
activities and at the direction of trust clients, Northern Trust lends
securities owned by clients to borrowers who are reviewed and approved by the
Credit Policy Credit Approval Committee. In connection with these activities,
Northern Trust has issued certain indemnifications against loss resulting from
the bankruptcy of the borrower of securities. The borrowing party is required
to fully collateralize securities received with cash, marketable securities, or
irrevocable standby letters of credit. As securities are loaned, collateral is
maintained at a minimum of 100 percent of the fair value of the securities plus
accrued interest, with revaluation of the collateral on a daily basis. The
amount of securities loaned as of December 31, 2002 and 2001 subject to
indemnification was $49.2 billion and $48.0 billion, respectively. Because of
the requirement to fully collateralize securities borrowed, management believes
that the exposure to credit loss from this activity is remote.
   The Bank is a participating member of various cash, securities and foreign
exchange clearing and settlement organizations such as The Depository Trust
Company in New York. It participates in these organizations on behalf of its
clients and on behalf of itself as a result of its own investment and trading
activities. A wide variety of cash and securities transactions are settled
through these organizations, including those involving

                          NORTHERN TRUST CORPORATION 81

                   Notes to Consolidated Financial Statements

obligations of states and political subdivisions, asset-backed securities,
commercial paper, dollar placements and securities issued by the Government
National Mortgage Association.
   As a result of its participation in cash, securities and foreign exchange
clearing and settlement organizations, the Bank could be responsible for a pro
rata share of certain credit-related losses arising out of the clearing
activities. The method in which such losses would be shared by the clearing
members is stipulated in each clearing organization's membership agreement.
Credit exposure related to these agreements varies from day to day, primarily
as a result of fluctuations in the volume of transactions cleared through the
organizations. The estimated credit exposure at December 31, 2002 and 2001 was
$48 million and $23 million, respectively, based on the membership agreements
and clearing volume for those days. Controls related to these clearing
transactions are closely monitored to protect the assets of Northern Trust and
its clients.

22. Fair Value of Financial Instruments--SFAS No. 107, "Disclosures About Fair
Value of Financial Instruments," requires disclosure of the estimated fair
value of certain financial instruments. Considerable judgment is required to
interpret market data when computing estimates of fair value. Accordingly,
the estimates presented are not necessarily indicative of the amounts Northern
Trust could have realized in a market exchange.
   The information provided below should not be interpreted as an estimate of
the fair value of Northern Trust since the disclosures, in accordance with SFAS
No. 107, exclude the values of nonfinancial assets and liabilities, as well
as a wide range of franchise, relationship, and intangible values, which are
integral to a full assessment of the consolidated financial position.
   The use of different assumptions and/or estimation methods may have a
material effect on the computation of estimated fair values. Therefore,
comparisons between Northern Trust's disclosures and those of other financial
institutions may not be meaningful.
   The following methods and assumptions were used in estimating the fair
values of the financial instruments:
       Securities. Fair values of securities were based on quoted market
values, when available. If quoted market values were not available, fair values
were based on quoted market values for comparable instruments.
   Loans (not including lease financing receivables). The fair values of
one-to-four family residential mortgages were based on quoted market prices of
similar loans sold, adjusted for differences in loan characteristics. The fair
values of the remainder of the loan portfolio were estimated using a discounted
cash flow method in which the discount rate used was the rate at which Northern
Trust would have originated the loan had it been originated as of the financial
statement date, giving effect to current economic conditions on loan
collectibility.
   Savings Certificates, Other Time, Foreign Offices Time Deposits and Other
Borrowings. The fair values of these instruments were estimated using a
discounted cash flow method that incorporated market interest rates.
   Senior Notes, Long-Term Debt, and Floating Rate Capital Securities. Fair
values were based on quoted market prices, when available. If quoted market
prices were not available, fair values were based on quoted market prices for
comparable instruments.
   Off-Balance Sheet Financial Instruments. The fair values of commitments and
letters of credit represent the amount of unamortized fees on these
instruments. The fair values of all other off-balance sheet financial
instruments were estimated using market prices, pricing models, or quoted
market prices of financial instruments with similar characteristics.
   Financial Instruments Valued at Carrying Value. Due to their short maturity,
the respective carrying values of certain on-balance sheet financial
instruments approximated their fair values. These financial instruments include
cash and due from banks; money market assets; customers' acceptance liability;
trust security settlement receivables; federal funds purchased; securities sold
under agreements to repurchase; commercial paper; certain other borrowings; and
liability on acceptances.
   The fair values required to be disclosed for demand, savings, and money
market deposits pursuant to SFAS No. 107 must equal the amounts disclosed in
the consolidated balance sheet, even though such deposits are typically priced
at a premium in banking industry consolidations.

of $1.4 billion of available for sale securities which were pledged as
collateral for agreements to repurchase securities sold transactions. The
secured parties to these transactions have the right to repledge or sell these
securities.
   Northern Trust is permitted to repledge or sell collateral accepted from
agreements to resell securities purchased transactions. The total fair value of
accepted collateral as of December 31, 2002 and 2001 was $328.6 million and
$1.6 billion, respectively. The fair value of repledged collateral as of
December 31, 2002 and 2001 was $88.7 million and $1.2 billion, respectively.
Repledged collateral was used in other agreements to repurchase securities sold
transactions. Deposits maintained at the Federal Reserve Bank to meet reserve
requirements averaged $525.4 million in 2002 and $382.2 million in 2001.

24. Stock-Based Compensation Plans--A description of Northern Trust's
stock-based compensation is presented below.

2002 Stock Plan. Effective April 16, 2002, the Corporation adopted the Northern
Trust Corporation 2002 Stock Plan (the "Plan") to replace the Northern Trust
Corporation Amended 1992 Incentive Stock Plan (1992 Plan). The Plan is
administered by the Compensation and Benefits Committee (Committee) of the
Board of Directors. All employees of the Corporation and its subsidiaries and
all directors of the Corporation are eligible to receive awards under the Plan.
The Plan provides for the grant of incentive stock options, nonqualified stock
options, stock appreciation rights, stock awards, performance shares and stock
units. The total number of shares of the Corporation's common stock authorized
for issuance under the Plan is 22,000,000. As of December 31, 2002, shares
available for future grant under the plan totaled 18,798,431.

1992 Plan. The 1992 Plan was adopted in 1992 and has been amended on several
occasions. The 1992 Plan is administered by the Committee. Directors and key
officers of the Corporation or its subsidiaries were eligible to receive awards
under the 1992 Plan. Awards under the 1992 Plan included incentive stock
options, nonqualified stock options, stock appreciation rights, stock awards,
performance shares, and stock units or equivalents. The 1992 Plan expired by
its terms on April 30, 2002 and no awards may be granted under the 1992 Plan
after
that date.
   The following description applies to awards under the Plan and the 1992
Plan, as applicable.
   Stock Options. Stock options consist of options to purchase common stock at
purchase prices not less than 100% of the fair market value thereof on the date
the option is granted. Options have a maximum ten-year life and generally vest
and become exercisable in six months to three years after the date of grant. In
addition, all options may become exercisable upon a "change of control" as
defined in the Plan or the 1992 Plan. All options terminate at such time as
determined by the Committee and as provided in the terms and conditions of the
respective option grants.
   Stock and Stock Unit Awards. Stock or stock unit awards can be granted by
the Committee to participants which entitle them to receive a payment in cash
or Northern Trust Corporation common stock under the terms of the Plan or the
1992 Plan and such other terms and conditions as the Committee deems
appropriate.
   Total expense applicable to stock and stock unit awards including dividend
equivalents was $13.4 million in 2002, $12.7 million in 2001, and $8.3 million
in 2000. In 2002, 2001 and 2000, 256,264 stock units, 292,500 stock units and
374,500 stock units, respectively, were granted with a weighted average
grant-date fair value of $50.92, $67.32 and $69.02, respectively. As of
December 31, 2002, restricted stock awards and stock units outstanding totaled
1,473,551 shares, of which 277,055 shares are fully vested with distribution
deferred. These shares generally vest, subject to continuing employment, over a
period of one to nine years.
   Performance Shares. Under the performance share provisions, participants are
entitled to have each award credited to an account maintained for them if
established performance goals are achieved. Distribution of the award is then
made after vesting. The value of shares that have not been distributed is
credited to performance share accounts and is shown in stockholders' equity as
Common Stock Issuable-Stock Incentive Plans.
   Total compensation expense for performance shares was $10.6 million in 2002,
$19.1 million in 2001 and $32.3 million in 2000. As of December 31, 2002,
801,000 shares of stock had been credited to performance share accounts subject
to meeting vesting conditions. The last grant of performance shares was in 1998.

Director Stock Awards. In January 2000, each non-employee director received a
grant of 2,400 stock units under the 1992 Plan, with 800 stock units vesting on
election or reelection as a director of the Corporation in each of the years
2000, 2001 and 2002. In January 2003, each non-employee director received a
grant of 2,400 stock units under the Plan, with 800 units vesting on election
or re-election as a director of the Corporation in each of the years 2003, 2004
and 2005. Directors may elect to defer the payment of their annual stock unit
grant and cash-based compensation until termination of services as director.
Amounts deferred are converted into stock units representing shares of common
stock of the Corporation. Distributions of deferred stock units will be made in
stock. Distributions of the stock unit account that relate to cash-based
compensation will be made in cash based on the fair value of the stock units.

Other Stock-Based Compensation Arrangements. Total compensation expense related
to restricted shares granted in conjunction with an acquisition was $2.0
million in 2002, $2.2 million in 2001 and $2.4 million in 2000. As of
December 31, 2002, restricted stock outstanding totaled 408,848 shares.

25. Cash-Based Compensation Plans--Various incentive plans provide for cash
incentives and bonuses to selected employees based upon accomplishment of
corporate net income objectives, business unit goals and individual
performance. The plans provide for acceleration of benefits in certain
circumstances including a change in control. The estimated contributions to
these plans are charged to salary expense and totaled $84.8 million in 2002,
$99.7 million in 2001 and $139.4 million in 2000.

26. Business Segments and Related Information--Information regarding the
Corporation's major business segments is contained in the Results of Operations
tables included in the section titled Business Segments beginning on page 40
and is incorporated by reference.
   The operations of Northern Trust are managed on a business unit basis and
include components of both domestic and foreign source income and assets.
Foreign source income and assets are not separately identified in its internal
management reporting system. However, in order to comply with the financial
reporting requirements of the Securities and Exchange Commission, Northern
Trust is required to disclose foreign

                   Notes to Consolidated Financial Statements

activities based on the domicile of the customer. Due to the complex and
integrated nature of its foreign and domestic activities, it is impossible to
segregate with precision revenues, expenses and assets between its U.S. and
foreign-domiciled customers. Therefore, certain subjective estimates and
assumptions have been made to allocate revenues, expenses and assets between
domestic and international operations as described below.
   Northern Trust's international activities are centered in the global
custody, treasury activities, foreign exchange, investment management and
commercial banking businesses of the Bank, three overseas branches, one Edge
Act subsidiary, foreign subsidiaries located in Canada, United Kingdom, Ireland
and Hong Kong, NTGA, and Northern Trust Bank of Florida. Net income from
international operations includes the direct net income contributions of
foreign branches, foreign subsidiaries and the Edge Act subsidiary. The Bank
and Northern Trust Bank of Florida international profit contributions reflect
direct salary and other expenses of the business units, plus expense
allocations for interest, occupancy, overhead and the provision for credit
losses. For purposes of this disclosure, all foreign exchange profits have been
allocated to international operations. Interest expense is allocated to
international operations based on specifically matched or pooled funding.
Allocations of indirect noninterest expenses related to international
activities are not significant but, when made, are based on various methods
such as time, space and number of employees.
   The table below summarizes international performance based on the domicile
of the primary obligor without regard to guarantors or the location of
collateral.

   *Operating Income is comprised of net interest income and noninterest income.

27. Acquisitions--In May 2000, Northern Trust completed the purchase
acquisition of Carl Domino Associates, L.P., a registered investment advisor in
West Palm Beach, Florida, for $21 million. Subsequent to acquisition, the
company became an operating division of Northern Trust Investments, Inc., known
as Northern Trust Value Investors. The transaction was recorded under the
purchase method of accounting. Included in the acquisition cost was $15 million
of goodwill and $4 million of other intangibles.
   In May 2000, Northern Trust completed the purchase acquisition of Ulster
Bank Investment Services Limited (UBIS), the IFSC (International Financial
Service Centre) licensed custody and fund administration subsidiary of Ulster
Bank Group for $14.3 million. Subsequent to the acquisition, the company was
renamed Northern Trust (Ireland) Limited. The transaction was recorded under
the purchase method of accounting. Included in the acquisition cost was $4.3
million of goodwill and $4.5 million of other intangibles.
   In January 2003, Northern Trust closed its acquisition of Deutsche Bank AG's
global passive equity, enhanced equity and passive fixed income businesses.
Under the terms of the agreement, Northern Trust paid approximately $100
million primarily based on assets under management of $44.1 billion. This
payment takes into consideration certain assets that are expected to transition
during the next several months. Additional payments will also be made, as other
assets are transitioned later this year.
   On November 22, 2002, Northern Trust signed a definitive agreement to
acquire Legacy South, an Atlanta-based private wealth management firm that
services high net worth individuals, families and private foundations. Legacy
South, established in 1996, has approximately $300 million of assets under
management as of year end. The purchase price is based on the total value of
revenues represented by managed assets transferred. The agreement is subject to
regulatory approvals and other customary closing conditions, and is expected to
close in the first quarter of 2003.

28. Regulatory Capital Requirements--Northern Trust and its subsidiary banks,
are subject to various regulatory capital requirements administered by the
federal bank regulatory authorities. Under these requirements, banks must
maintain specific ratios of total and tier 1 capital to risk-weighted assets
and of tier 1 capital to average assets in order to be classified as "well
capitalized." The regulatory capital requirements impose certain restrictions
upon banks that meet minimum capital requirements but are not "well
capitalized" and obligate the federal bank regulatory authorities to take
"prompt corrective action" with respect to banks that do not maintain such

                                    [GRAPHIC]

                   Notes to Consolidated Financial Statements

minimum ratios. Such prompt corrective action could have a direct material
effect on a bank's financial statements.
   As of December 31, 2002, each of Northern's subsidiary banks had capital
ratios above the level required for classification as a "well capitalized"
institution and had not received any regulatory notification of a lower
classification. There are no conditions or events since that date that
management believes have adversely affected the capital categorization of any
subsidiary bank for these purposes. The table below summarizes the risk-based

   Domestic bank regulatory authorities and international bank supervisory
organizations, principally the Basel Committee on Banking Supervision
(Committee), have proposed for comment and are considering changes to the
risk-based capital adequacy framework that could affect the capital guidelines
applicable to bank holding companies and banks. In December 2001, the Committee
indicated its desire to issue a new consultative package on the new Basel
Capital Accord (BCA). In July 2002, the Committee announced its intention to
finalize the new BCA in the fourth quarter of 2003, with implementation of the
BCA capital adequacy framework by year-end 2006. The Corporation is monitoring
the status and progress of the proposed rule and evaluating the potential
impact the BCA, if adopted, would have on the financial condition or results of
the operations of the Corporation and its banking subsidiaries.

                    Report of Independent Public Accountants

To the Stockholders and Board of Directors of Northern Trust Corporation:
We have audited the accompanying consolidated balance sheet of Northern Trust
Corporation (a Delaware corporation) and subsidiaries as of December 31, 2002
and 2001, and the related consolidated statements of income, comprehensive
income, changes in stockholders' equity and cash flows for each of the years in
the three year period ended December 31, 2002. These financial statements are
the responsibility of the Corporation's management. Our responsibility is to
express an opinion on these financial statements based on our audits.
   We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
   In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Northern Trust Corporation
and subsidiaries as of December 31, 2002 and 2001, and the results of their
operations and their cash flows for each of the years in the three year period
ended December 31, 2002 in conformity with accounting principles generally
accepted in the United States.

                                                                       KPMG LLP
