Notes to Consolidated Financial Statements

1.  Basis of Presentation - The consolidated financial statements include the
accounts of Northern Trust Corporation (Corporation) and its subsidiaries

intercompany balances and transactions have been eliminated. The consolidated
financial statements as of September 30, 2002 and 2001 have not been audited by

3. Pledged Assets - Securities and loans pledged to secure public and trust
deposits, repurchase agreements and for other purposes as required or permitted
by law were $9.6 billion on September 30, 2002, $10.5 billion on December 31,
2001 and $9.6 billion on September 30, 2001. Included in the September 30, 2002
pledged assets were securities available for sale of $923.3 million, 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 from agreements to
resell securities purchased transactions. The total fair value of accepted
collateral as of September 30, 2002, December 31, 2001 and September 30, 2001
was $323.3 million, $1.6 billion and $1.0 billion, respectively. The fair value
of repledged collateral as of September 30, 2002, December 31, 2001 and
September 30, 2001 was $215.6 million, $1.2 billion and $257.1 million,
respectively. Repledged collateral was used in other agreements to repurchase
securities sold transactions.

4. Contingent Liabilities - Standby letters of credit outstanding were $2.6
billion on September 30, 2002, $2.5 billion on December 31, 2001 and $2.4
billion on September 30, 2001.

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

                                        7

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 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
Corp.-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 Northern Trust Company (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 defendant company 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 that
these matters will be resolved without material impact on the Corporation's
consolidated financial position or results of operations.

At September 30, 2002, other domestic and international loans included $850.9

Notes to Consolidated Financial Statements (continued)

At September 30, 2002, nonperforming loans and leases totaled $106.5 million.
Included in this amount were loans with a recorded investment of $104.4 million
(net of $25.4 million in charge-offs) which were also classified as impaired. A
loan is impaired when, based on available information, it is probable that a
creditor will be unable to collect all amounts due according to the contractual
terms of the loan agreement. Impaired loans totaling $12.7 million (net of $15.2
million in charge-offs) had no portion of the reserve for credit losses
allocated to them while impaired loans totaling $91.7 million (net of $10.2
million in charge-offs) had an allocated reserve of $21.8 million. For the third
quarter of 2002, the total recorded investment in impaired loans averaged $106.0
million. There was $15 thousand of interest income recorded on impaired loans
for the quarter ended September 30, 2002.

At September 30, 2001, nonperforming loans and leases totaled $114.2 million and
included $112.8 million (net of $22.1 million in charge-offs) of impaired loans.
Of these impaired loans, $25.3 million (net of $8.9 million in charge-offs) had
no portion of the reserve for credit losses allocated to them while $87.5
million (net of $13.2 million in charge-offs) had an allocated reserve of $20.1
million. Total recorded investment in impaired loans for the third quarter of
2001 averaged $107.2 million with $66 thousand of interest income recognized on
such loans. The $12.6 million net decrease from September 30, 2001 to September
30, 2002 in impaired loans where no reserve has been assigned was caused
primarily by the sale of one large commercial loan during the fourth quarter of
2001.

At September 30, 2002, residential real estate loans totaling $20.6 million were
held for sale and were included in other assets in the consolidated balance
sheet.

Loan commitments for residential real estate loans, which when funded will be
held for sale, are carried at fair value while all other loan commitments are
carried at the amount of unamortized fees. At September 30, 2002, legally
binding commitments to extend credit totaled $15.7 billion, compared to $16.4
billion at December 31, 2001 and $15.9 billion at September 30, 2001.

Notes to Consolidated Financial Statements (continued)

In the second quarter of 2002, Northern Trust began to record the reserve for
unfunded commercial loan commitments, standby letters of credit and derivatives
in a liability account included in other liabilities on the consolidated balance
sheet. Previously, this portion of the reserve was included in the reserve for
credit losses and shown as a contra-asset on the consolidated balance sheet.
Prior period amounts have been reclassified.

The reserve for credit losses represents management's estimate of probable
inherent losses that 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 reserve 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, which depend upon internal credit ratings. These loss factors
primarily include management's judgment concerning the effect of the business
cycle on the creditworthiness of Northern Trust's borrowers as well as
historical charge-off experience.

Unallocated Inherent Reserve. Management determines the unallocated portion of
the inherent 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 reserve reflects management's attempt to
ensure that the overall reserve appropriately reflects a margin for the
imprecision inherent in the process of estimating expected credit losses.

Notes to Consolidated Financial Statements   (continued)

9.   The Northern Trust Corporation 2002 Stock Plan - The Board of Directors
approved the Northern Trust Corporation 2002 Stock Plan (the "2002 Plan"), which
was then subsequently approved by the Corporation's stockholders at the 2002
annual meeting of stockholders. The 2002 Plan is a compensation plan authorizing
the grant of stock options, stock appreciation rights, stock awards, performance
shares and stock units. An aggregate of 22,000,000 shares of the Corporation's
Common Stock has been reserved for issuance under the 2002 Plan. The 2002 Plan
replaces the Northern Trust Corporation Amended 1992 Incentive Stock Plan (the
"1992 Plan"). No awards may be granted under the 1992 Plan after April 30, 2002.

Statement of Financial Accounting Standards (SFAS) 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.

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. A description of Northern
Trust's stock-based compensation is presented in greater detail on pages 85
through 87 of the 2001 Annual Report to Shareholders.

10.  Accounting Standards Pronouncements - The following accounting standards
were adopted by Northern Trust in 2002.

Emerging Issues Task Force (EITF) 01-14, "Income Statement Characterization of
Reimbursements Received for `Out-of-Pocket' Expenses Incurred." Beginning in the
third quarter 2002, Northern Trust adopted EITF 01-14, 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 operating
expenses, and totaled $7.4 million and $22.7 million for the third quarter and
nine months of 2002, respectively, compared with $8.1 million and $24.2 million
for the same periods of 2001. Prior period amounts have been reclassified.

SFAS No. 142, "Goodwill and Other Intangible Assets" supersedes 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.

                                       12



Notes to Consolidated Financial Statements (continued)

   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 an 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 determined that no transitional impairment charge was
necessary. Goodwill at both January 1, 2002 and September 30, 2002 totaled $90.1
million. Application of the nonamortization provisions of the Statement will
reduce noninterest expense by approximately $10.0 million annually, resulting in
an increase in net income of approximately $8.0 million in 2002 compared to
2001. Goodwill amortization in the first nine months of 2001 totaled $7.4
million or $6.0 million after taxes.

   Intangible Assets Subject to Amortization - Other separately identifiable
acquired intangible assets will continue to be amortized over their estimated
useful life. At September 30, 2002, acquired intangible assets had a book value
of $30.2 million, which was net of accumulated amortization on these assets of
$57.5 million. Amortization for the first nine months of the year amounted to
$4.9 million. Amortization expense for the years ended 2002, 2003, 2004, 2005
and 2006 is estimated to be $6.7 million, $6.6 million, $6.6 million, $5.5
million and $5.1 million, respectively.

11.  RemitStream Investment - Northern Trust accounts for its 20% equity
interest in RemitStream Solutions LLC (RemitStream) using the equity method of
accounting.

12.  Business Combinations - On September 27, 2002, the Bank signed a definitive
agreement for the purchase of Deutsche Bank AG's global passive equity, enhanced
equity and passive fixed income businesses. The transaction is expected to close
within three to six months, subject to regulatory approval and other closing
conditions. The purchase price is based on the total value of revenues
represented by managed assets transferred. Based on assets under management as
of June 30, 2002 of $120 billion, the purchase price would be approximately $260
million, subject to adjustments.

13.  Business Segments - The tables on page 19, reflecting the earnings
contribution of Northern Trust's business segments for the third quarter and
nine months ended September 30, 2002, are incorporated by reference.

                                       13



Item 2.         MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS

THIRD QUARTER RESULTS OF OPERATIONS

Net income per common share on a diluted basis was $.43 for the third quarter, a
decrease of 22% from $.55 earned in the year-ago quarter. Net income totaled
$96.4 million, compared to $126.6 million reported for the third quarter of last
year. This earnings performance produced an annualized return on average common
equity (ROE) of 13.69% versus 19.63% reported for the comparable quarter last
year, and an annualized return on average assets (ROA) of 1.05% versus 1.43% in
2001. The current quarter's results include a $15.0 million investment write-off
($.04 per common share) of an equity investment in myCFO, Inc. and a $20.0
million provision for credit losses compared to $5.0 million in last year's
third quarter. The business environment during the quarter remained very
challenging given the significant and persistent weakness in equity markets
which has continued to adversely influence earnings performance. In this
difficult environment, Northern Trust continued to closely manage expenses,
which were up just 2% compared to last year's third quarter. Revenues, which
included the investment write-off, were down 5% from last year resulting in a
productivity ratio of 149%.

Noninterest Income

Noninterest income totaled $370.5 million for the quarter compared to $397.9
million last year, and accounted for 70% of total taxable equivalent revenue.
Trust fees were $298.0 million in the quarter, down 4% compared to $311.1
million in the third quarter of last year and represented 56% of total taxable
equivalent revenue. The decline in trust fees resulted primarily from weak
equity markets and was partially offset by new business. Trust assets under
administration totaled $1.44 trillion, a decrease of 8% since September 2001,
and trust assets under the management of Northern Trust fell 7% to $293.2
billion.

     *Previously reported total trust assets and managed assets in C&IS at June
     30, 2002 ($10.8 billion reduction) and prior quarters have been adjusted to
     eliminate a duplicate calculation in compiling a specific component of
     these amounts. This adjustment had no impact on revenues or net income.

Trust fees are based on the market value of assets managed and administered, the
volume of transactions, securities lending volume and spreads, and fees for
other services rendered. Asset-based trust 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 trust fee income.
In addition, certain accounts may

                                       14



Noninterest Income (continued)

be on a fixed annual fee. Therefore, market value or other changes in a
portfolio's size do not typically have a directly proportionate impact on the
level of the fees. In addition, Corporate and Institutional Services (C&IS)
trust relationships are increasingly priced to reflect earnings from activities
such as custody-related deposits and foreign exchange trading which are not
included in trust fees.

Trust fees from Personal Financial Services (PFS) in the quarter decreased 4%
and totaled $147.5 million compared to $153.9 million in the year-ago quarter.
The decline in PFS trust fees primarily resulted from the continued decline in
the equity markets, partially offset by new business. Northern Trust's network
of PFS offices totals 82 locations in twelve states. Personal trust assets under
administration totaled $150.7 billion at September 30, 2002 compared to $149.8
billion at September 30, 2001 and $163.4 billion at June 30, 2002. Of the total
assets under administration, $85.8 billion is managed by Northern Trust,
compared to $89.8 billion one year ago and $91.8 billion at June 30, 2002. With
the exception of Florida and California locations where trust assets are
revalued throughout the quarter, trust fees in PFS are largely based on the
level of trust assets at the end of the previous quarter. Thus, trust fees in
the fourth quarter, will be negatively impacted by the lower level of trust
assets at the end of the third quarter. At September 30, 2002, 40% of personal
trust assets under management were invested in equity securities. Net new
recurring PFS trust business transitioned during the first nine months totaled
approximately $29 million in annualized fees.

Trust fees from C&IS in the quarter decreased 4% to $150.5 million compared to
$157.2 million in the year-ago quarter. The decline resulted from lower
securities lending fees, which totaled $17.0 million compared to $29.3 million
in last year's third quarter. In the prior year quarter, securities lending fees
benefited from two decreases in the federal funds rate and higher volumes. Fees
from asset management increased 2% and totaled $47.4 million, compared with
$46.6 million in the year-ago quarter, driven primarily by growth in
institutional money market funds. Custody fees increased 4% to $56.8 million.
Northern Trust Retirement Consulting, L.L.C. recorded fees of $16.6 million
compared to $16.1 million in last year's third quarter.

C&IS trust assets under administration totaled $1.29 trillion at September 30,
2002, compared to $1.42 trillion at September 30, 2001 and $1.49 trillion at
June 30, 2002. Of the C&IS trust assets under administration, $207.4 billion is
managed by Northern Trust, down from $226.3 billion at September 30, 2001 and
$224.8 billion at June 30, 2002. Asset-based fees in C&IS are largely based on
the level of trust assets at the end of the previous quarter. Thus, trust fees
in the fourth quarter, will be negatively impacted by the lower level of trust
assets at the end of the third quarter. At September 30, 2002, approximately 22%
of assets under management were invested in equity securities. Trust assets
under administration include $448.5 billion of global custody assets, up 6% from
a year ago. Net new recurring C&IS trust business transitioned during the first
nine months totaled approximately $29 million in annualized fees.

                                       15



Noninterest Income (continued)

Foreign exchange trading profits were $26.3 million for the quarter, compared to
$37.2 million in the third quarter of last year. The current quarter reflects
lower client volumes and reduced market volatility in major currencies.

Treasury management revenues, which include both fees and the computed value of
compensating deposit balances, were $29.9 million, up 2% from last year's third
quarter, due to new business and higher transaction volumes from existing
clients. The fee portion of these revenues in the quarter was $23.9 million, up
11% from $21.5 million in the comparable quarter last year, partly as a result
of more clients paying for services in fees rather than in compensating deposit
balances.

Revenues from security commissions and trading income were $11.6 million, up 43%
from the prior year. Other operating income was $10.6 million for the third
quarter compared to $20.0 million in the same period last year. Current quarter
other operating income was reduced by a $15.0 million write-off of the
investment in myCFO, Inc., offset in part by the recognition of approximately
$8.5 million in gains by Norlease, Inc. from the sales of leased equipment in
the normal course of business at the end of scheduled lease terms.

Northern Trust's equity investment in myCFO, Inc. of Mountain View, California
was made in the first quarter of 2001 to complement Northern Trust's Wealth
Management's business strategy. In September 2002, myCFO, Inc. announced the
planned sale of its assets at an amount that is not expected to result in a
distribution of any sales proceeds to equity holders. This proposed sale
resulted in the write-off of Northern Trust's entire investment in this company
in the quarter.

Net Interest Income

Net interest income for the quarter totaled $149.9 million, 1% higher than the
$149.0 million reported in the third quarter of 2001. 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
hedging activity. When net interest income is 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 the quarter was $162.1
million, compared to $161.6 million reported in the third quarter of 2001. Total
average earning assets of $32.4 billion increased 3% from last year's third
quarter, while the net interest margin decreased to 1.98% from 2.05%.

Earning assets for the third quarter averaged $32.4 billion compared to $31.4
billion in last year's third quarter. Money market assets averaged $8.3 billion,
up from $5.7 billion last year, while the securities portfolio averaged $6.5
billion, down from $7.7 billion in the prior year. Loans and leases averaged
$17.6 billion in the quarter, down 2% from the third quarter of last year.

                                       16



Net Interest Income (continued)

Domestic loans outstanding were virtually unchanged, averaging $17.3 billion
compared with $17.1 billion in last year's third quarter, while international
loans decreased by $475 million from a year ago to average $308 million.
Residential mortgages increased $563 million, or 8%, to average $7.8 billion for
the quarter and represented 44% of the total loan portfolio. Commercial and
industrial loans averaged $4.2 billion, down $646 million or 13% from a year
ago.

Northern Trust utilizes a diverse mix of funding sources. Total interest-related
deposits averaged $18.0 billion, up 1% from the third quarter of 2001. Foreign
office time deposits increased $579 million as a result of increased global
custody activity, offset by lower levels of nonpersonal time deposits. Other
interest-related funds averaged $9.1 billion in the quarter compared with $8.4
billion in last year's third quarter. The increase in other interest-related
funds was due primarily to higher levels of overnight federal funds purchased.
The balances within these classifications vary based on funding requirements and
strategies, interest rate levels, changes in the volume of lower cost deposit
sources, and the availability of collateral to secure these borrowings.
Noninterest-related funds increased 4% from the prior year, averaging $5.3
billion.

Provision for Credit Losses

The provision for credit losses was $20.0 million in the quarter compared to
$5.0 million for the same quarter last year and $5.0 million in the second
quarter of 2002. For a discussion of the provision and reserve for credit
losses, refer to the Asset Quality section beginning on page 24.

Noninterest Expenses

Noninterest expenses totaled $357.2 million for the quarter, up 2% from $351.7
million in the year-ago quarter. Expenses continue to be closely monitored
through various initiatives implemented by management to control certain expense
categories, including controlling staff levels and limiting staff-related and
other discretionary costs.

Compensation and employee benefits represented 57% of total operating expenses
and totaled $204.0 million, virtually unchanged from a year ago. The results
reflect the impact of lower average staff levels resulting from the close
management of head count and the outsourcing of the lockbox operations and a
decrease in performance-based pay offset by salary increases and higher benefit
costs. The cost of lockbox operations is now included in other operating
expenses as a direct payment for services. Staff on a full-time equivalent basis
at September 30, 2002 totaled 9,328, a decline of 125 positions since year-end.
Between June 30, 2002 and September 30, 2002 staff declined 56 positions on a
full-time equivalent basis.

                                       17



Noninterest Expenses (continued)

Net occupancy expense totaled $28.3 million, up 9% from $25.8 million in the
third quarter of 2001. The increase was due primarily to the relocation of
London Branch staff to Canary Wharf, the remodeling of existing offices over the
past twelve months and additional space leased to support planned growth. The
principal components of the increase in occupancy expense were higher net rental
costs and amortization expense of leasehold improvements.

Equipment expense, comprised of depreciation, rental and maintenance costs,
totaled $22.6 million, up 9% from $20.8 million reported in the third quarter of
2001. The increase was concentrated primarily in depreciation and maintenance of
computer hardware.

Other operating expenses in the quarter totaled $102.3 million compared to
$100.9 million last year. Other expense categories reflect increased costs
associated with technology investments, office expansion, and lockbox servicing
payments. These increases were partially offset by initiatives to manage costs
that resulted in decreases in various expenses, including travel and other
discretionary costs. In addition, the adoption of new accounting requirements in
2002 to eliminate goodwill amortization costs reduced expenses by $2.2 million
or $1.8 million after-tax. The following table shows the components of other
operating expenses.

Provision for Income Taxes

The provision for income taxes was $46.8 million for the third quarter compared
with $63.6 million in the year-ago quarter. The lower tax provision in 2002
resulted primarily from lower federal taxable earnings, partially offset by
higher state income taxes brought about by a reduction in income exempt for
state tax purposes. The effective tax rate for the quarter was 32.7%, compared
with 33.4% in the third quarter of 2001.

Corporate and Institutional Services

C&IS net income for the quarter totaled $40.8 million, down 33% from $60.9
million reported in 2001. Noninterest income was 3% lower than the third quarter
of 2001 and totaled $219.0 million. Trust fees decreased 4% to $150.5 million in
the current quarter compared to $157.2 million in the year-ago quarter, due
primarily to a $12.3 million or 42% decline in securities lending fees to $17.0
million. In the prior year quarter, securities lending fees benefited from two
decreases in the federal funds rate and higher volumes. Fees from asset
management increased 2% during the current quarter and totaled $47.4 million,
compared with $46.6 million in the year-ago quarter, driven primarily by growth
in institutional money market funds. Custody fees increased 4% to $56.8 million
and fees generated by Northern Trust Retirement Consulting, L.L.C. were $16.6
million compared with $16.1 million in last year's third quarter. Other
noninterest income was $68.5 million, virtually unchanged from $68.2 million in
last year's third quarter. Foreign exchange trading profits were $26.1 million,
down 29% from $36.7 million in the prior year's third quarter. Partially
offsetting this reduction was the recognition of approximately $8.5 million in
gains by Norlease, Inc. from the sales of leased equipment in the normal course
of business at the end of scheduled lease terms. Higher letter of credit and
treasury management fees also contributed to the current quarter's performance
compared with the year-ago period.

Net interest income after the provision for credit losses, stated on a FTE
basis, was $24.8 million, down 47% from $46.9 million in last year's third
quarter. The decrease primarily reflects a provision for credit losses for the
quarter of $19.3 million, compared to $3.1 million in the prior year third
quarter. This $16.2 million increase in the provision was caused by various
factors including: the charge-off of the remaining amount outstanding on the
unsecured loan to Enron Corp.; a partial charge-off on another large commercial
loan; and the migration of certain loans to weaker rated credit categories
brought on by the prolonged economic downturn. In addition, net interest income
was impacted by lower levels of earning assets, concentrated primarily in money
market assets and loans, with each asset category declining 11% from last year's
average. The net interest margin was 1.22% for the current quarter compared with
1.23% in last year's third quarter.

Noninterest expenses increased 3% to $177.1 million in the current quarter
compared with $172.7 million in last year's third quarter. The increase
primarily reflects higher costs associated with technology investments, the
relocation of London staff to Canary Wharf, lockbox servicing payments and
allocations for product and operations support. These increases were partially
offset by lower compensation levels. Compensation costs were lower than the
previous year due to lower average FTE staff levels resulting from the
outsourcing of the lockbox operations and lower performance-based pay. The
adoption of new accounting requirements in 2002 that eliminates goodwill
amortization costs reduced expenses by $.8 million compared to the third quarter
of last year.

                                       20



Personal Financial Services

PFS net income for the quarter was $58.2 million, 13% below the $66.9 million
reported a year ago. Noninterest income was $152.3 million in the current
quarter compared with $172.0 million in last year's third quarter. The decline
was primarily due to the $15.0 million write-off of the investment in myCFO,
Inc. in addition to a 4% reduction in trust fees, which totaled $147.5 million
in the current quarter. The decline in PFS trust fees primarily resulted from
the continued decline in the equity markets partially offset by new business.

Net interest income after the provision for credit losses, stated on a FTE
basis, increased 7% to $113.3 million in the current quarter. The improved
results reflect a $1.2 million decrease in the provision for credit losses, a 3%
increase in average loans concentrated in the mortgage loan portfolio, and an
improvement in the net interest margin from 2.95% last year to 3.06% in the
current quarter.

Noninterest expenses increased to $171.3 million in the current quarter from
$169.0 million in last year's third quarter. Compensation and employee benefits
were 2% below the prior year as the effects of merit increases and higher
benefit costs were more than offset by lower performance-based incentive pay and
lower staffing levels. Occupancy costs were $10.4 million or 14% higher as a
result of the remodeling and expansion of existing locations, while outside
services purchased increased $1.4 million to $5.6 million in this year's third
quarter. Allocations for product and operations support increased $3.2 million
from last year's third quarter to $75.4 million. Partially offsetting the above
was the adoption of new accounting requirements in 2002 that eliminates goodwill
amortization costs, which reduced expenses by $1.4 million.

Treasury and Other

The Treasury Department is responsible for managing the Bank's wholesale
funding, capital position and interest rate risk, as well as the investment
portfolio. "Other" corporate income and noninterest expenses represent items
that are not allocated to the business units and generally represent certain
nonrecurring items and certain executive level compensation. Net interest income
for the third quarter was $4.0 million compared to $3.7 million in the year-ago
quarter. Noninterest expenses totaled $8.8 million for the quarter compared to
$10.0 million in the year-ago period reflecting lower performance-based
incentives.

                                       21



NINE-MONTH RESULTS OF OPERATIONS

Net income per common share on a diluted basis of $1.54 was 7% lower than the
$1.66 reported in the nine months ended September 30, 2001. Net income was
$350.8 million compared with $385.1 million earned last year. The ROE was 17.16%
for the first nine months compared with 20.72% last year, while the ROA was
1.26% compared with 1.44% in the previous year. Total revenues were 2% lower
than the prior year while total expenses increased 1%, resulting in a
productivity ratio of 155% compared with 160% last year.

Noninterest Income

Noninterest income totaled $1.18 billion for the nine months ended September 30,
2002, accounting for 71% of total taxable equivalent revenue. Trust fees totaled
$940.1 million, down 1% from $947.8 million in the same period of last year and
represented 56% of total taxable equivalent revenue.

Trust fees from PFS in the nine-month period decreased 1% and totaled $460.8
million compared with $465.6 million last year. The decline in PFS trust fees
primarily resulted from the continued decline in the equity markets, partially
offset by new business.

Trust fees from C&IS also decreased 1% to $479.3 million compared with $482.2
million in the year-ago period. The decline resulted from lower securities
lending fees, which totaled $79.2 million, compared with $102.0 million last
year. In the prior year, securities lending fees benefited from eight decreases
in the federal funds rate and higher volumes. Fees from asset management
increased 5% and totaled $142.0 million, compared with $135.5 million in the
year-ago period, driven primarily by growth in institutional money market funds.
Custody fees increased 2% to $166.7 million. Northern Trust Retirement
Consulting, L.L.C. recorded fees of $55.1 million compared with $50.1 million
last year.

Foreign exchange trading profits totaled $87.5 million for the nine-month
period, 22% below the $112.6 million in the prior year. Treasury management
revenues from both fees and the computed value of compensating deposit balances
increased 2% to $89.9 million. The fee portion of these revenues accrued in the
period totaled $71.9 million, up 13% from $63.5 million in 2001, partly as a
result of more clients paying for services in fees rather than in compensating
deposit balances. Revenues from security commissions and trading income rose 19%
to $31.2 million. Other operating income totaled $47.0 million in the period
compared with $67.7 million in 2001. The current year results have been reduced
by the $15.0 million write-off of the investment in myCFO, Inc., partially
offset by the recognition of approximately $8.5 million in gains by Norlease,
Inc. from the sales of leased equipment at the end of scheduled lease terms. The
prior year included a $9.2 million nonrecurring gain recorded in the second
quarter of last year. The remainder of the decline for the period resulted
primarily from lower levels of trust deposit-related revenues due to lower
interest rates.

                                       22



Net Interest Income

Net interest income, stated on a FTE basis, totaled $486.2 million compared with
$484.3 million reported last year. Earning assets averaged $33.1 billion for the
nine months compared with $32.1 billion in the same period of 2001. Money market
assets averaged $8.7 billion, up from $4.9 billion last year, while the
securities portfolio averaged $6.8 billion, down from $9.3 billion in the prior
year. Loans and leases averaged $17.6 billion, down 1% from the same period of
2001.

Provision for Credit Losses

The $30.0 million provision for credit losses was $8.5 million higher than the
$21.5 million provision in 2001. The increase in the year-to-date provision for
credit losses primarily relates to the $20.0 million third quarter provision
discussed in the Asset Quality section beginning on page 24. The provision for
credit losses last year included $6.5 million related to the sale of $44.5
million of nonperforming loans. Net charge-offs totaled $23.2 million and
represented .18% of average loans compared with $26.3 million or .20% of average
loans in 2001.

Noninterest Expenses

Noninterest expenses totaled $1.07 billion for the nine months ended September
30, 2002, up 1% from $1.06 billion in the year-ago period.

Compensation and employee benefits represented 56% of total operating expenses
and totaled $603.3 million, down 2% from a year ago, as the impact of
outsourcing lockbox services and lower performance-based pay offset salary
increases and higher benefit costs.

Net occupancy expense totaled $80.3 million, up 6% from $75.8 million in the
prior year. The principal components of the increase were higher rent,
amortization of leasehold improvements and building maintenance costs.

Equipment expense, comprised of depreciation, rental and maintenance costs,
totaled $68.0 million, up 7% from $63.6 million in 2001. The current nine-month
period reflects higher levels of depreciation and maintenance of computer
hardware and data line lease costs.

Other operating expenses totaled $319.6 million for the nine-month period, up 4%
from $306.3 million in 2001. Other expense categories reflect increased costs
associated with processing errors incurred in servicing and managing financial
assets and performing banking activities, technology investments, office
expansion, and payments made to RemitStream for receivables management and
lockbox services. The increase in processing errors was the result of two
unusually large losses experienced in corporate actions and recorded in this
year's second quarter. Partially offsetting these increases was the adoption of
new accounting requirements in 2002 to eliminate goodwill amortization costs,
which reduced expenses by $7.4 million or $6.0 million after-tax.

                                       23



BALANCE SHEET

Total assets at September 30, 2002 were $39.7 billion and averaged $36.5 billion
for the third quarter, up 4% from last year's average of $35.1 billion. Loans
and leases totaled $17.9 billion at September 30, 2002 and averaged $17.6
billion for the third quarter, compared with $18.8 billion at September 30, 2001
and $17.9 billion for the third quarter of last year. Securities totaled $8.1
billion at September 30, 2002 and averaged $6.5 billion for the quarter,
compared with $6.0 billion at September 30, 2001 and $7.7 billion on average in
last year's third quarter. Money market assets totaled $8.9 billion at September
30, 2002 and averaged $8.3 billion in the third quarter, up 44% from the
year-ago quarter as proceeds from the maturities of short-term federal agency
securities were reinvested in time deposits with banks.

Driven by the retention of earnings, offset in part by stock repurchases under
the Corporation's ongoing share buyback program, common stockholders' equity
increased to $2.83 billion at September 30, 2002 and averaged $2.78 billion for
the quarter, up 9% from the $2.54 billion average in last year's third quarter.
Total stockholders' equity averaged $2.90 billion compared with $2.66 billion in
the third quarter of 2001.

During the quarter, the Corporation acquired a total of 1.1 million shares of
its common stock at a cost of $43.4 million. An additional 1.9 million shares
may be purchased after September 30, 2002 under the previously announced share
buyback program.

Northern Trust's risk-based capital ratios remained strong at 10.9% for tier 1
capital and 13.9% for total capital at September 30, 2002. These ratios are well
above the minimum regulatory requirements of 4% for tier 1 and 8% for total
risk-based capital ratios. The leverage ratio (tier 1 capital to third quarter
average assets) of 8.2% at September 30, 2002, also exceeded the minimum
regulatory requirement of 3%. The Bank's risk-based capital ratios at September
30, 2002 were 9.4% for tier 1 capital, 12.4% for total capital and 7.0% for the
leverage ratio. Each of Northern Trust's other subsidiary banks had a ratio of
10.7% or higher for tier 1 capital, 11.3% for total risk-based capital, and 7.8%
for the leverage ratio.

ASSET QUALITY

Nonperforming assets consist of nonaccrual loans and other real estate owned
(OREO). Nonperforming assets at September 30, 2002 totaled $107.6 million,
compared with $110.6 million at June 30, 2002, $109.5 million at December 31,
2001 and $115.8 million at September 30, 2001. Domestic nonaccrual loans and
leases, consisting primarily of commercial loans, totaled $106.5 million, or
..60% of total domestic loans and leases at September 30, 2002. At June 30, 2002,
December 31, 2001 and September 30, 2001, domestic nonaccrual loans and leases
totaled $109.7 million, $108.7 million and $114.2 million, respectively. The
$3.2 million decrease in nonperforming loans during the quarter is the result of
an additional $15.2 million in loans classified as nonaccrual, offset by $10.2
million in charge-offs and $8.2 million in loan repayments and loan sales.

                                       24



ASSET QUALITY (continued)

The following table presents the outstanding amounts of nonaccrual loans and
OREO. Also shown are loans that have interest or principal payments that are
delinquent 90 days or more and are still accruing interest. The increase in
loans past due 90 days or more has been impacted by the prolonged economic
downturn. The balance in this category at any quarter-end can fluctuate widely

Provision and Reserve for Credit Losses

The provision for credit losses is the charge against current earnings that is
determined, through a disciplined credit risk management process, as 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 reserve) 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
reserve).

Note 6 to the Consolidated Financial Statements includes a table that analyzes
the reserve for credit losses for the nine-month periods ended September 30,
2002 and September 30, 2001 and identifies the charge-offs, recoveries and the
provision for credit losses during the respective periods. The table on the
following page shows (i) the specific reserve, (ii) the allocated portion of the
inherent reserve and its components by loan category, and (iii) the unallocated
portion of the inherent reserve at September 30, 2002, June 30, 2002, December
31, 2001 and September 30, 2001.

- ---------------------------------------------------------------------------------------------------------------------------------


Specific Reserve. At September 30, 2002, the specific component of the reserve
stood at $21.8 million, compared to $24.4 million at June 30, 2002. The $2.6
million reduction in the specific component of the reserve during the quarter
reflects a $10.0 million charge-off of the remaining amount of the unsecured
loan to Enron Corp., based on management's determination that such action was
warranted. A portion of this charge-off had been provided for in a prior
quarter. Partially offsetting this decrease were additional reserves provided
primarily on middle market commercial loans, which continued to reflect
deterioration in credit quality due to the prolonged economic downturn.

Allocated Inherent Reserve. The allocated inherent portion of the reserve
increased by a net $11.8 million during the quarter to $125.6 million at
September 30, 2002. The change in this component of the reserve primarily
reflects the migration of various commercial loans to lower rated credit
categories where higher provision factors are applied. The credit rating
adjustments are a result of the downturn in the general economy that has
adversely affected the credit quality of certain large corporate and middle
market lending clients. The changes in the credit ratings are a reflection of
Northern's most recent evaluations and the results of the annual, industry-wide
Shared National Credit review conducted by the banking regulators.

Management does not believe that the circumstances that caused the credit loss
on the Enron Corp. unsecured loan 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, based on the charge-off of the Enron Corp. credit.

                                       26



Provision and Reserve for Credit Losses (continued)

Unallocated Inherent Reserve. The unallocated portion of the inherent reserve is
based on management's review of overall factors affecting the determination of
probable losses primarily inherent in the commercial 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. The unallocated inherent portion of the reserve was $21.0
million, a decrease of $1.1 million from June 30, 2002, reflecting management's
judgment that there have been only minor changes in the factors affecting this
component of the reserve.

Other Factors. At September 30, 2002, there were no significant changes in
concentration of credits that impacted asset quality. 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), was $319 million, of which $104.2 million was classified as
impaired, up from $278 million at June 30, 2002, when $107.4 million was
impaired, and up from $311 million at September 30, 2001 when $111.5 million was
impaired. The increase from June 30, 2002 reflects the migration of certain
loans to lower credit ratings offset in part by the charge-off of the remaining
unsecured loan to Enron Corp., a partial charge-off on another commercial loan
and paydowns on other loans.

Total Reserve. Management's evaluation of the factors above resulted in a
reserve for credit losses of $168.4 million at September 30, 2002, $8.1 million
above that at June 30, 2002. The reserve of $160.3 million assigned to loans and
leases, as a percentage of total loans and leases was .89% at September 30,
2002, compared to .84% at June 30, 2002.

Reserves assigned to unfunded loan commitments, standby letters of credits and
derivative products totaled $8.1 million at September 30, 2002, an increase of
$1.1 million from June 30, 2002. This change resulted from the increase in the
volume of these activities.

Provision. The provision for credit losses was $20.0 million during the third
quarter of 2002, compared to $5.0 million in the prior year quarter. The
provision for the current quarter reflects the impact of management's ongoing
credit evaluations and the results of the annual, industry-wide Shared National
Credit regulatory reviews.

MARKET RISK MANAGEMENT

As described in the 2001 Annual Report to Shareholders, Northern Trust manages
its interest rate risk through measurement techniques which include simulation
of earnings, simulation of the economic value of equity, and gap analysis. Also,
as part of its risk management activities, it regularly measures the risk of
loss associated with foreign currency positions using a value at risk model.

Based on this continuing evaluation process, Northern Trust's interest rate risk
position and the value at risk associated with the foreign exchange trading
portfolio have not changed significantly since December 31, 2001.
