At March 31, 2002, other domestic and international loans included $843.0
million of overnight trust-related advances, primarily in connection with next
day security settlements, compared with $812.0 million at December 31, 2001 and
$1.0 billion at March 31, 2001.

At March 31, 2002, nonperforming loans and leases totaled $117.9 million.
Included in this amount were loans with a recorded investment of $116.1 million,
which were also classified as impaired. A loan is impaired when, based on
current 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 $14.6 million had no portion of the reserve for credit
losses allocated to them while impaired loans totaling $101.5 million had an
allocated reserve of $24.6 million. For the first quarter of 2002, the total
recorded investment in impaired loans averaged $112.1 million. There was $29
thousand of interest income recorded on impaired loans for the quarter ended
March 31, 2002.

At March 31, 2001, nonperforming loans and leases totaled $111.1 million and
included $107.7 million of impaired loans. Of these impaired loans, $10.6
million had no portion of the reserve for credit losses allocated to them while
$97.1 million had an allocated reserve of $29.0 million. Total recorded
investment in impaired loans for the first quarter of 2001 averaged $82.5
million with no interest income recognized on such loans.

At March 31, 2002, commercial loans and residential real estate loans totaling
$41.4 million were held for sale and were included in other assets in the
consolidated balance sheet.

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 necessarily inherent in estimates of expected credit losses.

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

                                       10



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") which expired by its terms on April 30, 2002. No awards may be granted
under the 1992 Plan after that date.

10. Accounting Standards Pronouncements - The following accounting standards or
disclosures were adopted in the first quarter of 2002.

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.

   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 March 31, 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 quarter of 2001 totaled $2.6 million or
$2.1 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 March 31, 2002, acquired intangible assets had a book value of
$33.5 million, which was net of accumulated amortization on these assets of
$54.2 million. Amortization for the first three months of the year amounted to
$1.6 million. Amortization expenses for the years 2002, 2003, 2004, 2005 and
2006 are estimated to be $6.7 million, $6.6 million, $6.6 million, $5.5 million
and $5.1 million, respectively.

SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets"
supersedes SFAS No. 121 and the accounting and reporting provisions of APB
Opinion No. 30. The Statement addresses the accounting for a segment of a
business accounted for as a discontinued operation and the accounting for
long-lived assets to be disposed of. The provisions of this Statement are
effective for financial statements issued for fiscal years beginning after
December 15, 2001. Northern Trust adopted the requirements of this Statement on
January 1, 2002. It is not anticipated that the adoption of SFAS No. 144 will
have a material effect on Northern Trust's results of operations.

                                       11



Emerging Issues Task Force Guidance Under Topic D-96, "Accounting for Management
Fees Based on a Formula", requires that effective with the quarter ended March
31, 2002, that Northern Trust disclose its accounting policy for revenue
recognition under arrangements that contain a performance-based incentive fee
that is not finalized until the end of a period of time specified in the
contract. Consistent with the prior year, Northern Trust adheres to a policy in
which it does not record any incentive 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 has not
recorded any revenue under these 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 match the treatment for the related
performance-based revenues. No performance-based incentive fees or expenses were
recognized in the quarter ended March 31, 2002.

11. Business Segments - The table on page 18, reflecting the earnings
contribution of Northern Trust's business segments for the first quarter ended
March 31, 2002, are incorporated by reference.

                                       12



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

FIRST QUARTER EARNINGS HIGHLIGHTS

Net income per common share on a diluted basis increased 2% to $.56 for the
first quarter, up from $.55 earned a year ago. Net income totaled $127.6
million, compared to $127.2 million reported for the first quarter of last year.
This earnings performance produced an annualized return on average common equity
(ROE) of 19.42% versus 21.53% reported for the comparable quarter last year, and
an annualized return on average assets (ROA) of 1.37% versus 1.45% in 2001. This
performance was achieved as a result of continued aggressive management of
expenses, which were flat compared to last year. Revenue growth was also flat,
resulting in a productivity ratio of 161%.

Noninterest Income

Noninterest income totaled $391.7 million for the quarter, accounting for 71% of
total taxable equivalent revenue. Trust fees were $316.4 million in the quarter,
up 4% compared to $305.2 million in the first quarter of last year and
represented 57% of total taxable equivalent revenue. The trust fee growth
resulted primarily from new business and was partially offset by weak equity
markets. Trust assets under administration totaled $1.72 trillion, an increase
of 4% since March 2001, and trust assets under the management of Northern Trust
grew modestly to $337.7 billion.

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 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.

                                       13



Noninterest Income (continued)

Trust fees from Personal Financial Services (PFS) in the quarter increased 2%
and totaled $158.6 million, compared to $156.1 million in the year-ago quarter.
The increase in PFS trust fees resulted from new business and was partially
offset by weak equity markets. Northern Trust's network of Personal Financial
Services offices now totals 82 locations in twelve states, and it is currently
estimated that there will be approximately 100 offices operating within as many
as fifteen states by the end of 2005. Personal trust assets under administration
totaled $173.4 billion at March 31, 2002, compared to $160.0 billion at March
31, 2001 and $166.8 billion at December 31, 2001. Of the total trust assets
under administration, $96.2 billion is managed by Northern Trust, compared to
$93.3 billion one year ago. At March 31, 2002, 49% of personal trust assets
under management were invested in equity securities. Net new recurring PFS trust
business sold in the first three months totaled approximately $11 million in
annualized fees.

Trust fees from C&IS in the quarter increased 6% to $157.8 million, compared to
$149.1 million in the year-ago quarter. Driven primarily by growth in
institutional money market funds, fees from asset management increased 9% and
totaled $48.2 million, compared to $44.2 million in the year-ago quarter.
Reflecting strong global business, custody fees increased 3% to $52.4 million.
Northern Trust Retirement Consulting, L.L.C. recorded fees of $17.6 million
compared to $15.3 million in last year's first quarter. Securities lending fees
totaled $28.8 million compared to $29.9 million in last year's first quarter. In
the prior year, securities lending spreads benefited from three declines in the
federal funds rate during the quarter.

C&IS trust assets under administration totaled $1.54 trillion at March 31, 2002,
compared to $1.49 trillion at March 31, 2001 and $1.52 trillion at December 31,
2001. Of the C&IS trust assets under administration, $241.5 billion is managed
by Northern Trust, down slightly from $243.3 billion at March 31, 2001, but up
from $236.1 billion at year-end. At March 31, 2002, approximately 25% of assets
under management were invested in equity securities. Trust assets under
administration included $470.4 billion of global custody assets, up 13% from a
year ago. Net new recurring C&IS trust business sold in the first three months
totaled approximately $8 million in annualized fees.

Foreign exchange trading profits were $24.3 million for the quarter, compared to
$34.9 million in the first quarter of last year. Northern Trust's foreign
exchange trading volumes were lower and foreign exchange markets in major
currencies continued to lack volatility, resulting in reduced revenues for the
quarter.

Treasury management revenues, which include both fees and the computed value of
compensating deposit balances, totaled $29.8 million, up 4% from last year's
first quarter, due to new business and higher transaction volumes from existing
clients. The fee portion of these revenues in the quarter was $23.4 million, up
16% from $20.1 million in the comparable quarter last year, partly as a result
of more clients electing to pay for services in fees rather than in compensating
deposit balances.

                                       14



Noninterest Income (continued)

Revenues from security commissions and trading income totaled $9.9 million, up
3% from the prior year, driven primarily by higher commissions on fixed income
securities. Other operating income was $17.7 million for the first quarter
compared with $19.7 million in the same period of last year. The decrease
reflects lower levels of trust deposit-related revenues due to lower interest
rates.

Net Interest Income

Net interest income for the quarter totaled $149.2 million, 1% higher than the
$148.1 million reported in the first 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
off-balance sheet 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 $160.9 million, down slightly from $162.0 million reported in the first
quarter of 2001. Although total average earning assets of $34.0 billion were up
6% from last year's first quarter, the net interest margin declined to 1.92%
from 2.05%. The net interest margin was impacted by a $1.8 billion increase in
short-term, lower-spread assets and a decline in the value of
noninterest-related funds due to lower interest rates.

Earning assets for the first quarter averaged $34.0 billion, up $1.8 billion or
6% from last year's first quarter. The growth was driven by a $4.4 billion
increase in money market assets, partially offset by a 26% decline in the
securities portfolio to $7.3 billion on average. Loans and leases averaged $17.7
billion in the quarter, unchanged from the prior year.

Domestic loans increased slightly to average $17.2 billion, while international
loans decreased by $258 million from a year ago to average $463 million.
Residential mortgages increased $635 million, or 9%, to average $7.5 billion for
the quarter and represented 42% of the total loan portfolio. Commercial and
industrial loans averaged $4.6 billion, down 9% from a year ago, while personal
loans declined 6% to $2.1 billion.

                                       15



Net Interest Income (continued)

The funding for earning assets is provided by a diverse mix of funding sources
available to Northern Trust. Total interest-related deposits averaged $17.7
billion, down slightly from $17.9 billion in the first quarter of 2001. Foreign
office time deposits increased $528 million as a result of increased global
custody activity and money market deposits increased $892 million. This growth
was offset by a decrease in savings certificates and non-personal time deposits.
Other interest-related funds averaged $10.8 billion in the quarter compared to
$9.3 billion in last year's first quarter. The increase in other
interest-related funds was due primarily to higher levels of overnight federal
funds purchased and treasury investment program balances, offset in part by
reductions in repurchase agreements and term 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 9% to average $5.4 billion due to growth in
demand deposits and to a higher level of common stockholders' equity resulting
from retained earnings.

Provision for Credit Losses

The provision for credit losses was $5.0 million in the first quarter, unchanged
from the same quarter last year but down from the $45.0 million provision in the
fourth quarter of 2001. For a discussion of the provision and reserve for credit
losses, refer to the Asset Quality section beginning on page 20.

Noninterest Expenses

Noninterest expenses totaled $342.8 million for the quarter, virtually unchanged
from $341.6 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 approximately 58% of total
operating expenses and totaled $198.2 million, down 3% from $204.2 million in
the comparable quarter last year. Staff growth, salary increases and higher
benefit costs were more than offset by lower performance-based pay. Staff on a
full-time equivalent basis at March 31, 2002 totaled 9,408, a decline of 45
positions since year-end and an increase of 2% since March 31, 2001, after
adjusting for the impact of the lockbox joint venture initiated during the third
quarter of last year.

Net occupancy expense totaled $26.0 million, up 6% from $24.7 million in the
first quarter of 2001, due primarily to the opening of new PFS offices and
remodeling existing offices over the past twelve months and additional space
leased to support growth in other business units. The principal components of
the increase in occupancy expense were higher net rental costs, real estate
taxes and amortization expense of leasehold improvements.

                                       16



Noninterest Expenses (continued)

Equipment expense, comprised of depreciation, rental and maintenance costs,
totaled $22.6 million, up 6% from the $21.2 million reported in the first
quarter of 2001. The increase was concentrated primarily in depreciation and
maintenance of computer hardware and increased costs for data line leases.

Other operating expenses in the quarter totaled $96.0 million compared to $91.5
million last year. The increase in other operating expenses reflects increased
costs associated with technology investments, operating costs relating to the
significant growth in transaction volumes, and payments made to the lockbox
joint venture. Previously, the cost of the lockbox operations was primarily
included in compensation and employee benefits. Additionally, last year's first
quarter benefited from lower stock-related directors compensation due to the
decline in the price of Northern Trust Corporation common stock from the
previous year-end. These increases were partially offset by initiatives to
manage costs that resulted in decreases in various expense categories, including
travel, hiring and other discretionary costs. In addition, the adoption of new
accounting requirements in 2002 to eliminate goodwill amortization costs reduced
expenses by $2.6 million or $2.1 million after-tax. The following table shows
the components of other operating expenses.

Provision for Income Taxes

The provision for income taxes was $65.5 million for the first quarter compared
with $63.8 million in the year-ago quarter. The higher tax provision in 2002
resulted primarily from the growth in taxable earnings for both federal and
state income tax purposes. The effective tax rate for the first quarter was
33.9% compared to 33.4% for the first quarter of 2001.

Note:  Certain reclassifications have been made to 2001 financial information to
conform to the current year presentation.

Corporate and Institutional Services

C&IS net income for the quarter totaled $54.6 million, down 4% from $57.2
million reported in 2001. Noninterest income was unchanged from the first
quarter of 2001 and totaled $214.3 million. Trust fees increased 6% to $157.8
million in the current quarter compared to $149.1 million in the year-ago
quarter, due primarily to a 9% increase in asset management fees, a 3% increase
in custody fees and a 15% increase in fees generated by Northern Trust
Retirement Consulting, L.L.C. Other noninterest income was $56.5 million, down
13% from $65.2 million in last year's first quarter. The decline reflects a 30%
reduction in foreign exchange trading profits due to lower client trading
volumes and a lack of volatility in major currencies. Partially offsetting this
reduction was a $2.3 million increase in fees for treasury management services
due to new business, higher transaction volumes from existing clients and more
clients electing to pay for services in fees rather than in compensating deposit
balances.

Net interest income after the provision for credit losses, stated on a FTE
basis, was $42.4 million, down 8% from $46.3 million in last year's first
quarter. The decrease reflects a decline in the net interest margin to 1.26%
from 1.34% in the prior year quarter, partially offset by a $5.0 million
decrease in the provision for possible credit losses assigned to this segment.
The lower interest margin resulted from the significant decline in short-term
interest rates which reduced the value of deposit funding that C&IS provides to
the Treasury and Other segment.

Noninterest expenses were virtually unchanged at $167.6 million in the current
quarter compared to $167.2 million last year. Lower compensation levels were
offset by increases in payments made to the lockbox joint venture. Compensation
costs were lower than the previous year due to both reductions in staff
resulting from the outsourcing of the lockbox operations and lower
performance-based pay. Previously the cost of the lockbox operations was
primarily included in compensation and employee benefits.

                                       18



Personal Financial Services

PFS net income for the quarter was $67.8 million, essentially unchanged from
$68.0 million reported a year ago. Noninterest income was $177.3 million in the
current quarter compared to $174.6 million in last year's first quarter. The
slight improvement was due primarily to a 2% increase in trust fees, which
totaled $158.6 million in the current quarter resulting from new business,
partially offset by weak equity markets. Other income totaled $18.7 million in
the current quarter, compared with $18.5 million in the prior year.

Net interest income after the provision for credit losses, stated on a FTE
basis, decreased 2% to $103.7 million in the current quarter. The decrease was
due primarily to a $5.0 million increase in the provision for credit losses
assigned to this segment and a slight reduction in the net interest margin,
partially offset by a 3% increase in average earning assets, concentrated in the
loan portfolio.

Noninterest expenses were virtually unchanged at $170.8 million in the current
quarter compared to $169.9 million in last year's first quarter. Compensation
and employee benefits increased 1% as the effects of staff growth, merit
increases and employee benefits were partially offset by lower performance-based
pay. Occupancy costs were $1.2 million or 13% higher as a result of opening new
PFS offices and the remodeling of existing locations. Partially offsetting the
above were business development expenses falling 12% below the prior year level
and, the adoption of new accounting requirements in 2002 to eliminate goodwill
amortization costs, which reduced expenses by an additional $1.3 million.

Treasury and Other

The Treasury Department is responsible for managing The Northern Trust Company's
(Bank) 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 first quarter was $9.8 million compared to $4.4
million in the year-ago quarter. The improvement resulted primarily from the
impact of lower interest rates which reduced the cost of the funds that the
Treasury and Other segment acquires from the C&IS business unit. Noninterest
expenses totaled $4.4 million for the quarter compared to $4.5 million in the
year-ago period.

                                       19



BALANCE SHEET

Total assets at March 31, 2002 were $38.0 billion and averaged $37.7 billion for
the first quarter, up 6% from last year's average of $35.7 billion. Loans and
leases totaled $17.8 billion at March 31, 2002 and averaged $17.7 billion for
the first quarter, each virtually unchanged from the respective periods of 2001.
Securities totaled $9.0 billion at March 31, 2002 and averaged $7.3 billion for
the quarter, compared to $12.7 billion at March 31, 2001 and $9.9 billion on
average in the first quarter of 2001. Money market assets totaled $7.7 billion
at March 31, 2002 and averaged $9.0 billion in the first quarter, up 98% from
the year-ago quarter.

Driven by the retention of earnings, offset in part by stock repurchases under
Northern Trust's ongoing stock buyback program, common stockholders' equity
increased to $2.71 billion at March 31, 2002 and averaged $2.65 billion for the
quarter, up 12% from the $2.37 billion average in last year's first quarter.
Total stockholders' equity averaged $2.77 billion compared with $2.49 billion in
the first quarter of 2001.

During the quarter, the Corporation acquired a total of 801,640 shares at a cost
of $46.0 million. An additional 3.8 million shares may be purchased after March
31, 2002 under the current stock buyback program.

Northern Trust's risk-based capital ratios remained strong at 11.0% for tier 1
capital and 14.3% for total capital at March 31, 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 first quarter
average assets) of 7.6% at March 31, 2002, also exceeded the minimum regulatory
requirement of 3%. The Bank's risk-based capital ratios at March 31, 2002 were
9.5% for tier 1 capital, 12.8% for total capital and 6.5% for the leverage
ratio. Each of Northern Trust's other subsidiary banks had a ratio of 11.4% or
higher for tier 1 capital, 12.3% 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 March 31, 2002 totaled $118.7 million, compared
with $109.5 million at December 31, 2001 and $112.7 million at March 31, 2001.
Domestic nonaccrual loans and leases, consisting primarily of commercial loans,
totaled $117.9 million, or .69% of total domestic loans and leases at March 31,
2002. At December 31, 2001 and March 31, 2001, domestic nonaccrual loans and
leases totaled $108.7 million and $111.1 million, respectively. The increase
during the quarter primarily reflects the further deterioration in two
commercial loans that have been significantly affected by the recent economic
downturn, offset in part by the sale of a commercial loan with asbestos-related
exposure.

                                       20



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 balance in this
category at any quarter-end can fluctuate widely based on the timing of cash
collections, renegotiations and renewals.

Provision and Reserve for Credit Losses

The provision for credit losses is the charge against current earnings that is
determined by management, through a disciplined credit review 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 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).

Note 6 to the Consolidated Financial Statements includes a table that analyzes
the reserve for credit losses for the three months ended March 31, 2002 and
March 31, 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 March 31, 2002, December 31, 2001 and March 31, 2001.

Specific Reserve. At March 31, 2002, the specific component of the reserve stood
at $24.6 million, compared to $21.1 million at December 31, 2001 and $29.0
million at March 31, 2001. The $3.5 million increase from year-end 2001 relates
primarily to further deterioration in two commercial loans that have been
significantly affected by the recent economic downturn, offset in part by the
sale of a commercial loan with asbestos-related exposure, whose loss in value
had been provided for in prior quarters.

Allocated Inherent Reserve. The allocated inherent portion of the reserve
decreased by $4.9 million during the quarter to $113.1 million at March 31,
2002, primarily reflecting the partial sale of another large commercial loan
with asbestos-related exposure and the impact of transferring certain loans to
nonperforming status where specific reserves are determined. These events were
partially offset by the impact of lowering the credit ratings on several
commercial loans due to the continued downturn in the economy.

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 $22.6
million, virtually unchanged from December 31, 2001, reflecting management's
judgment that there have been only minor changes in the factors affecting this
component of the reserve.

                                       22



Provision and Reserve for Credit Losses (continued)

Other Factors. During the quarter ended March 31, 2002, there were no
significant changes in concentration of credits that impacted asset quality at
the time reserve determinations were made for the quarter. At that time, 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 $267 million of which $115.5 million was
classified as impaired, down from $295 million at December 31, 2001 when $97.6
million was impaired. The decrease of $28 million in the current quarter
primarily reflects the sale of one commercial loan and the partial sale of
another, both of which were impacted by exposure to asbestos-related claims. At
March 31, 2001, loans rated "7" and "8" totaled $171 million, of which $107.7
million was impaired.

Total Reserve. Management's evaluation of the factors above resulted in a
reserve for credit losses of $160.3 million at March 31, 2002, compared to
$161.6 million at December 31, 2001. The reserve as a percentage of total loans
remained at .90% at March 31, 2002, the same as at December 31, 2001.

Provision. The resulting provision for credit losses was $5.0 million during the
first quarter of 2002.

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.

accounting standards and interpretations) on Northern Trust's business and
results. These statements speak of Northern Trust's plans, goals, beliefs or
expectations, refer to estimates or use similar terms. Actual results could
differ materially from the results indicated by these statements because the
realization of those results is subject to many uncertainties including:

..    The future health of the U.S. and international economies and other
     economic factors that affect wealth creation, investment and savings
     patterns, and Northern Trust's interest rate risk exposure and credit risk.

..    U.S. and international economic factors that may impact Northern Trust's
     interest rate risk exposure and credit risk.

..    Any extraordinary events (such as the September 11, 2001 events and the
     U.S. government's response to those events).

..    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.

     changing economic factors, political conditions or currency markets.

..    Regulatory developments and changes in accounting requirements or
     interpretations in the U.S. and other countries where Northern Trust has
     significant business.

..    Changes in the nature of Northern Trust's competition resulting from
     industry consolidation, enactment of the Gramm-Leach-Bliley Act of 1999,
     and other regulatory changes and other factors, as well as actions taken by
     particular competitors.

..    Northern Trust's success in continuing to generate new business in its
     existing markets, as well as its success in identifying and penetrating
     targeted markets, through acquisition or otherwise, and generating a profit
     in those markets in a reasonable time.

..    Northern Trust's ability to continue to generate strong investment results
     for clients and continue to develop its array of investment products,
     internally or through acquisition, in a manner that meets clients' needs.

                                       24

     volume and complexity in many of its businesses.

..    Northern Trust's success in integrating future acquisitions and using the
     acquired businesses to execute its business strategy.
