Notes to Consolidated Financial Statements

1. Basis of Presentation - The consolidated financial statements include the
accounts of Northern Trust Corporation and its subsidiaries (Northern Trust),
all of which are wholly-owned. Significant intercompany balances and
transactions have been eliminated. The consolidated financial statements as of
June 30, 2001 and 2000 have not been audited by the Corporation's public
accountants. In the opinion of management, all adjustments necessary for a fair
presentation of the financial position and the results of operations for the
interim periods have been made. All such adjustments are of a normal recurring
nature. Certain 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. For a description of Northern
Trust's significant accounting policies, refer to Note 1 of the Notes to
Consolidated Financial Statements in the 2000 Annual Report to Shareholders.

At June 30, 2001, other domestic and international loans included $1.2 billion
of overnight trust-related advances, primarily in connection with next day
security settlements, compared with $1.4 billion at December 31, 2000 and $1.3
billion at June 30, 2000.

At June 30, 2001, nonperforming loans and leases totaled $107.9 million.
Included in this amount were loans with a recorded investment of $105.0 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 $11.0 million had no portion of the reserve for credit
losses allocated to them while impaired loans totaling $94.0 million had an
allocated reserve of $23.4 million. For the second quarter of 2001, the total
recorded investment in impaired loans averaged $102.7 million. There was no
interest income recorded on impaired loans for the quarter ended June 30, 2001.

At June 30, 2000, nonperforming loans and leases totaled $54.4 million and
included $53.1 million of impaired loans. Of these impaired loans, $6.4 million
had no portion of the reserve for credit losses allocated to them while $46.7
million had an allocated reserve of $18.6 million. Total recorded investment in
impaired loans for the second quarter of 2000 averaged $54.1 million with no
interest income recognized on such loans.

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. Accounting Standards Pronouncements - In July 2001, the Financial Accounting
Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS)
No. 141, "Business Combinations", and No. 142, "Goodwill and Other Intangible
Assets".

SFAS No. 141 supersedes Accounting Principles Board (APB) Opinion No. 16,
"Business Combinations" and discontinues the use of the pooling-of-interests
method of accounting for business combinations as permitted under APB No. 16.
The provisions of SFAS No. 141 apply to all business combinations initiated
after June 30, 2001 and require that all business combinations be accounted for
by a single method-- the purchase method.

SFAS No. 142 supersedes APB Opinion No. 17, "Intangible Assets", and addresses
the accounting for goodwill and intangible assets. The provisions of this
Statement, as they relate to the Northern Trust, are required to be applied
beginning January 1, 2002 to all goodwill and other intangible assets reflected
in the financial statements at that date. 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. Goodwill at
June 30, 2001 totaled $95.8 million and is currently being amortized on a
straight-line method primarily over fifteen years. Goodwill amortization for the
six months ended June 30, 2001 amounted to $5.2 million. Other separately
identifiable acquired intangible assets will continue to be amortized over their
estimated useful life. At June 30, 2001, acquired intangible assets totaled
$38.5 million and amortization for the first six months of the year amounted to
$3.0 million.

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

SECOND QUARTER EARNINGS HIGHLIGHTS

Net income increased 7% to a record $131.3 million from the $123.0 million
earned in the second quarter of last year. Net income per common share on a
diluted basis increased 8% to $.57 for the second quarter, up from $.53 earned a
year ago. This earnings performance produced an annualized return on average
common equity (ROE) of 21.10% versus 22.81% reported last year, and an
annualized return on average assets (ROA) of 1.45% versus 1.44% in 2000. This
performance was achieved by strong growth in certain segments of Northern
Trust's diversified revenue base and effective expense management. Revenues
increased 5% and noninterest expense growth was held to 4%, which resulted in a
record productivity ratio of 163%.

The 21.10% ROE surpassed Northern Trust's minimum goal of 20% for the
seventeenth consecutive quarter and the productivity ratio of 163% also exceeded
the corporate goal of 160%. The 8% increase in earnings per common share was
below the long-term corporate goal of 10%.

Noninterest Income

Noninterest income increased 5% and totaled $414.3 million for the quarter,
accounting for 72% of total taxable equivalent revenue. Trust fees of $317.7
million increased 4% or $12.1 million over the like period of 2000 and
represented 77% of noninterest income and 55% of total taxable equivalent
revenue. Trust fee growth resulted from new business, offset in part by lower
equity markets. Trust assets under administration grew to $1.68 trillion, up 4%
since June 30, 2000, reflecting continued new business that overcame the effect
of lower equity markets. Trust assets under the management of Northern Trust
grew $8.5 billion since last year to $341.5 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 trust 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.

                                       12



Noninterest Income (continued)

Trust fees from Personal Financial Services (PFS) in the quarter totaled $154.7
million, compared to $152.6 million in the year-ago quarter. This performance
reflects continued new business throughout Northern Trust's national PFS
network, largely offset by lower equity markets. Total personal trust assets
under administration totaled $161.1 billion at June 30, 2001, and reflect the
transfer of $3.0 billion in assets to Corporate & Institutional Services (C&IS).
This compares to $165.0 billion at June 30, 2000. Of the total assets under
administration, $94.7 billion is managed by Northern Trust, compared to $97.7
billion one year ago. At June 30, 2001, approximately 55% of the personal trust
assets under administration and 51% of assets under management were invested in
domestic equity securities. Net new recurring PFS trust business sold during the
first six months totaled approximately $31 million in annualized fees.

Trust fees from C&IS in the quarter increased 7% to $163.0 million, compared to
$153.0 million in the year-ago quarter. C&IS trust fees are derived from a full
range of custody, investment and advisory services rendered to retirement and
other asset pools of corporate and institutional clients worldwide. Securities
lending fees increased 28% to a record $42.7 million and was the principal
contributor to the overall increase. The securities lending growth reflected
higher volumes and spreads earned on the investment of collateral. Custody fees
increased to $50.4 million, up 5%, reflecting new business. Fees from asset
management totaled $44.3 million and were $2.4 million below the year-ago
quarter, which included $4.7 million of performance-based fees compared to $.3
million in the current quarter. Northern Trust Retirement Consulting, L.L.C.
recorded fees of $15.1 million, up from $14.8 million in last year's second
quarter.

C&IS trust assets under administration totaled $1.52 trillion at June 30, 2001,
compared to $1.45 trillion at June 30, 2000. Of the C&IS trust assets under
administration, $246.8 billion is managed by Northern Trust, up 5% from June 30,
2000. At June 30, 2001, approximately 38% of assets under administration and 26%
of assets under management were invested in domestic equity securities. Trust
assets under administration included $439.3 billion of global custody assets.
Net new recurring C&IS trust business sold in the first six months totaled
approximately $40 million in annualized fees.

Foreign exchange trading profits were $40.5 million for the quarter, compared to
the record results of $42.1 million in the second quarter of 2000 and $34.9
million in the first quarter of 2001. These strong results reflect higher client
volume and volatility in major currencies including the yen, euro and British
pound.

Treasury management revenues, which include both fees and the computed value of
compensating deposit balances, totaled $28.9 million, up 7% from last year's
second quarter, due to new business and higher transaction volumes from existing
clients. The fee portion of these revenues in the quarter was $20.6 million, up
13% from $18.2 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.

                                       13



Noninterest Income (continued)

Revenues from security commissions and trading income totaled $8.5 million, up
3% from last year. Other operating income was $27.0 million for the second
quarter compared with $18.7 million in the same period of last year. The
increase reflects a $9.2 million nonrecurring gain on the previously announced
formation in June 2001 of a joint venture with Fiserv, Inc. to provide
receivables management or lockbox services to Northern Trust clients.
Approximately 400 Northern Trust employees will move to parallel positions with
Fiserv during the third quarter as part of the joint venture.

Net Interest Income

Net interest income for the quarter totaled $146.4 million, 4% higher than the
$140.8 million reported in the second quarter of 2000. 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 $160.7 million, up 4% from the $154.1 million reported in the second quarter
of 2000. The increase in net interest income reflects 6% growth in average
earning asset levels and a 12% increase in noninterest-related funding sources,
primarily demand deposits and equity. The Federal Reserve Open Market Committee
reduced the federal funds target rate from 6.50% at the start of 2001 to 3.75%
late in June, a major short-term rate decline of 2.75%. The net interest margin
narrowed to 1.96% versus 2.00% reported in the year-ago quarter. The modest
change in the net interest margin during a period of significant changes in
short-term rates reflects Northern Trust's policy of managing the balance sheet
to minimize the risk of interest rate fluctuations adversely impacting net
interest income.

Earning assets for the second quarter averaged $32.8 billion, up 6% from the
$30.9 billion average for the same quarter of 2000. The $1.9 billion growth in
average earning assets was comprised of a $1.6 billion or 10% increase in loans
and leases and moderately higher levels of securities and money market assets.

The loan growth was concentrated predominantly in the domestic portfolio, which
increased $1.4 billion to average $17.2 billion, while international loans
increased by $140 million to $766 million from a year ago. Reflecting strong
growth in lending to Wealth Management and private banking clients, personal
loans increased $317 million or 17% to average $2.2 billion on average for the
quarter. Residential mortgage loans, which represent 39% of the total average
loan portfolio, increased $571 million or 9% to average $7.0 billion for the
quarter. Commercial and industrial loans averaged $5.1 billion compared to $4.9
billion in last year's second quarter, while lease financing increased 47% to
average $1.1 billion.

                                       14



Net Interest Income (continued)

Funding for the growth in earning assets came from several sources. Total
interest-related deposits averaged $17.7 billion, up 7% or $1.2 billion from the
second quarter of 2000. This growth was concentrated primarily in savings, money
market deposits and savings certificates, up $481 million, non-personal time
deposits, up $380 million, and foreign office time deposits, up $362 million as
a result of increased global custody activity. Other interest-related funds
averaged $9.9 billion in the quarter compared to $9.8 billion in last year's
second quarter. Higher levels of federal funds purchased and borrowings from the
Federal Home Loan Bank were offset by a sharp decline in the level of treasury
tax deposit balances. The balances within these classifications vary based on
funding requirements and strategies, interest rate levels, growth in lower cost
deposit sources, and the availability of collateral to secure these borrowings.
Noninterest-related funds increased 12% to average $5.2 billion due to growth in
common stockholders' equity resulting from retained earnings, and to a higher
level of demand deposits.

Provision for Credit Losses

The provision for credit losses was $11.5 million in the second quarter compared
to $10.0 million for the same quarter last year and $5.0 million in the first
quarter of 2001. For a discussion of the provision and reserve for credit
losses, refer to the Asset Quality section beginning on page 21.

Noninterest Expenses

Noninterest expenses totaled $351.8 million for the quarter, an increase of 4%
or $13.6 million from the $338.2 million in the year-ago quarter. Expense growth
was once again held to a significantly lower rate than historically experienced,
partially as a result of initiatives implemented by management to control
certain expenses. These initiatives include controlling staff levels, limiting
staff-related and other discretionary expenses, and modifying some cash
incentive plans for 2001 to include a stock option grant component. This last
initiative, announced last quarter, resulted in a $5.5 million expense savings
in the current quarter when compared to programs in place prior to this
initiative. Compensation costs in the current quarter also included $1.7 million
of accelerated incentive plan costs related to retirements. Approximately 70% of
the increase in noninterest expenses related to compensation and employee
benefits and was primarily attributable to staff growth and merit increases,
partially offset by lower performance-based pay. The balance of the expense
growth reflects increased costs associated with technology investments
(including e-business initiatives), office expansion, and operating costs
relating to the significant growth in transaction volumes. These increases were
partially offset by a number of factors, including a reduction in
performance-based payments to investment sub-advisors.

                                       15



Noninterest Expenses (continued)

Compensation and employee benefits, which represent approximately 59% of total
noninterest expenses, increased to $207.0 million from $197.3 million in the
year-ago quarter. The increase was primarily attributable to staff growth and
merit increases, partially offset by lower performance-based pay.
Performance-based pay in the prior year quarter was impacted by strong new
business, excellent investment management performance, record net income and the
price increase in Northern Trust Corporation common stock compared to the
previous year. Current year compensation levels reflect the impact of slower
revenue growth, lower investment portfolio performance and the modifications
made to incentive plans. Staff on a full-time equivalent basis at June 30, 2001
totaled 9,646, up 6% from June 30, 2000. Since December 31, 2000, staff has
increased by only 180 positions, or less than 2%.

Net occupancy expense totaled $25.3 million, up 14% from $22.2 million in the
second quarter of 2000, due primarily to the opening of new or remodeled PFS
offices over the past twelve months and additional space leased to support
business growth. The principal components of the increase in occupancy expense
were higher net rental, operating and maintenance costs, real estate taxes and
utilities, building depreciation and amortization expense of leasehold
improvements.

Equipment expense, comprised of depreciation, rental and maintenance costs,
totaled $21.6 million, up 17% from the $18.5 million reported in the second
quarter of 2000. The increase was primarily in depreciation of computer hardware
and office furniture and equipment, higher maintenance costs for computers and
equipment, and increased costs for data line leases.

Other operating expenses in the quarter totaled $97.9 million compared to $100.2
million last year. The decline in other operating expenses 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 continued investment in technology, which included
costs to replace mainframe computer equipment, expansion of the PFS office
network and other expenditures to support business growth. The following table
shows the components of other operating expenses.

Provision for Income Taxes

The provision for income taxes was $66.1 million for the second quarter compared
with $62.5 million in the year-ago quarter. The higher tax provision in 2001
resulted primarily from the growth in taxable earnings for both federal and
state income tax purposes. The effective tax rate for the second quarter was
33.5% compared to 33.7% for the second quarter of 2000.

Corporate and Institutional Services

C&IS net income for the quarter totaled $73.1 million, up 12% from the second
quarter of 2000. Noninterest income increased 9% to $241.8 million in the second
quarter of 2001 from $221.8 million in last year's second quarter. Trust fees,
reflecting a record performance for securities lending fees, increased 7% to
$163.0 million in the current quarter compared to $153.0 million in the year-ago
quarter. Other income was $78.8 million, up 15% from $68.8 million in last
year's second quarter. The increase reflects a $9.2 million nonrecurring gain on
the previously announced formation of a joint venture with Fiserv, Inc. to
provide receivables management services to Northern Trust clients. The remainder
of the increase resulted from higher fees for treasury management services due
to new business, higher transaction volumes from existing clients and clients
electing to pay for services in fees rather than in compensating deposit
balances. Foreign exchange trading profits were down slightly from the record
performance in last year's second quarter.

Net interest income after the provision for credit losses, stated on a FTE
basis, was essentially unchanged at $45.2 million in the current quarter. A
slight improvement in net interest income, driven primarily by a 7% increase in
average earning assets, was offset by a $2.0 million increase in the provision
for possible credit losses.

Noninterest expenses increased 4% to $167.5 million in the current quarter due
primarily to staff growth, merit increases, higher occupancy costs and expense
allocations for product and operations support. Salaries and employee benefits
increased, resulting from staff growth and merit increases, but were partially
offset by lower performance-based pay. The overall increase in noninterest
expenses was partially offset by a reduction in charges associated with
processing errors incurred in servicing and managing financial assets and
performance-based payments to investment sub-advisors.

Personal Financial Services

PFS net income for the quarter was $59.6 million, 6% lower than the $63.7
million reported a year ago. Noninterest income increased to $170.8 million in
the current quarter from $168.6 million in last year's second quarter. The
increase was due primarily to an increase in trust fees, which totaled $154.7
million in the current quarter, resulting from new business throughout Northern
Trust's national PFS network, largely offset by lower equity markets. Other
income was essentially unchanged at $16.1 million in the current quarter.

Net interest income after the provision for credit losses, stated on a FTE
basis, increased 5% to $98.7 million in the current quarter. The increase was
due primarily to a $1.4 billion or 11% increase in average loan volume, offset
in part by a lower interest rate spread earned on the investment of retail
savings deposits.

                                       18



Personal Financial Services (continued)

Noninterest expenses increased 9% to $172.3 million in the current quarter from
$158.7 million in last year's second quarter. Higher expense allocations for
product and operations support accounted for $11.5 million of the total
increase. Salaries and employee benefits were unchanged as the effects of staff
growth and merit increases were offset by lower performance-based pay. In
addition, occupancy costs were $1.1 million or 15% higher as a result of opening
new PFS offices and the expansion of existing locations. The remainder of the
increase was the result of increased costs associated with technology
investments and operating costs relating to the significant growth in
transaction volumes.

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 second quarter was up slightly from a year ago
resulting primarily from the impact of falling interest rates in 2001.
Noninterest expenses totaled $12.0 million for the quarter compared with $18.8
million in last year's second quarter. The decline in operating expenses relates
to lower accruals for certain corporate-based incentive plans. In addition,
expenses were reduced as more occupancy related costs were allocated to the
business units as a result of the technology center, purchased in January 2000,
becoming fully utilized.

SIX-MONTH EARNINGS HIGHLIGHTS

Net income per common share increased 11% to $1.12 for the six-month period
ended June 30, 2001, up from $1.01 last year. Net income increased 9% to $258.5
million from $236.3 million in the year-ago period. The ROE was 21.31% compared
to 22.26% last year, while the ROA was unchanged at 1.45%. The productivity
ratio improved to 162% from 160% last year.

Total revenues, stated on a fully taxable equivalent basis, increased 6% from
2000 levels. Trust fees totaled $622.9 million, up 5% from $591.6 million last
year. Foreign exchange trading profits totaled $75.4 million, down 1% from last
year's strong performance. Treasury management revenues from both fees and the
computed value of compensating deposit balances increased 9% to $57.6 million.
The fee portion of these revenues accrued in the period totaled $40.7 million,
up 15% from $35.3 million from 2000 levels. Other operating income totaled $46.7
million in the period compared with $34.4 million in 2000. The increase from
last year is comprised of the $9.2 million nonrecurring gain recorded in the
second quarter, in addition to higher loan and trust deposit-related fees.

Net interest income, stated on a FTE basis, totaled $322.7 million, up 6% from
$304.9 million reported last year. The $16.5 million provision for credit losses
was $2.5 million higher than the $14.0 million required in the same period last
year. Noninterest expenses were up 4% and totaled $693.4 million compared to
$664.3 million a year ago.

BALANCE SHEET

Total assets at June 30, 2001 were $36.2 billion and averaged $36.3 billion for
the second quarter, up 6% from last year's average of $34.3 billion. Due to
continued credit demand, loans and leases grew to $18.2 billion at June 30, 2001
and averaged $18.0 billion for the quarter. This compares with $17.3 billion in
total loans and leases at June 30, 2000 and $16.4 billion on average for the
second quarter of last year. Securities totaled $9.5 billion at June 30, 2001
and averaged $10.3 billion for the second quarter, compared to $11.2 billion at
June 30, 2000 and $10.2 billion on average in the second quarter of 2000. Money
market assets totaled $4.0 billion at June 30, 2001 and averaged $4.5 billion in
the second quarter, up 3% from the year-ago quarter.

Driven by continued strong earnings growth, offset in part by stock repurchases
under Northern Trust's ongoing stock buyback program, common stockholders'
equity increased to $2.54 billion at June 30, 2001 and averaged $2.47 billion
for the quarter, up 15% from the $2.14 billion average in last year's second
quarter. Total stockholders' equity averaged $2.59 billion compared with $2.26
billion in the second quarter of 2000.

During the quarter, the Corporation acquired a total of 457,185 shares at a cost
of $30.0 million. An additional 6.2 million shares may be purchased after June
30, 2001 under the current stock buyback program.

Northern Trust's risk-based capital ratios remained strong at 10.5% for tier 1
capital and 14.0% for total capital at June 30, 2001. 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 second quarter
average assets) of 7.4% at June 30, 2001, also exceeded the minimum regulatory
requirement of 3%. The Bank's risk-based capital ratios at June 30, 2001 were
9.0% for tier 1 capital, 12.6% for total capital and 6.3% for the leverage
ratio. Each of Northern Trust's other subsidiary banks had a ratio of 10.6% or
higher for tier 1 capital, 11.1% for total risk-based capital, and 7.1% for the
leverage ratio.

                                       20



ASSET QUALITY

Nonperforming assets consist of nonaccrual loans and other real estate owned
(OREO). Nonperforming assets at June 30, 2001 totaled $109.4 million, compared
with $112.7 million at March 31, 2001, $78.5 million at December 31, 2000 and
$55.4 million at June 30, 2000. Domestic nonaccrual loans consisting primarily
of commercial loans, totaled $107.9 million, representing .62% of total domestic
loans and leases at June 30, 2001. At March 31, 2001, December 31, 2000 and June
30, 2000, domestic nonaccrual loans and leases totaled $111.1 million, $76.3
million and $54.4 million, respectively. The change during the second quarter
from March 31, 2001 reflects the sale in May of $44.5 million in nonperforming
loans, partially offset by the impact of commercial loans to two companies that
filed for Chapter 11 reorganization in late June and early July.

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).

                                       21



Provision and Reserve for Credit Losses (continued)

Note 6 to the Consolidated Financial Statements includes a table that analyzes
the reserve for credit losses for the six months ended June 30, 2001 and June
30, 2000 and identifies the charge-offs, recoveries and the provision for credit
losses during the respective periods. The table below 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
June 30, 2001, March 31, 2001, December 31, 2000 and June 30, 2000.

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



Specific Reserve. At June 30, 2001, the specific component of the reserve stood
at $23.4 million, compared to $29.0 million at March 31, 2001. The $5.6 million
reduction in the specific component of the reserve during the quarter reflects
management's decision to sell $44.5 million of nonperforming loans, offset in
part by the impact of commercial loans to two companies that filed for Chapter
11 reorganization. The charge-offs on the loan sales totaled $19.0 million, of
which $12.5 million was previously reserved for and $6.5 million was recognized
in the current quarter's provision for credit losses.

Allocated Inherent Reserve. The allocated inherent portion of the reserve
decreased by a net $1.7 million during the second quarter to $112.3 million at
June 30, 2001. The change in this component of the reserve reflects primarily
the impact of the transfer of two commercial loans to a rating category for
which specific reserves are provided, partially offset by increases in allocated
inherent reserves resulting from loan growth.

                                       22



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 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. The
unallocated inherent portion of the reserve was $24.0 million, a decrease of $.9
million from March 31, 2001, reflecting management's judgment that there has
been only minor changes in the factors affecting this component of the reserve.

Other Factors. During the quarter ended June 30, 2001, 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 $149 million, of which $104.7 million was classified as
impaired, down from $171 million at March 31, 2001 when $107.7 million was
classified as impaired, and up from $81 million at June 30, 2000 when $53
million was impaired. The decrease from March 31, 2001 primarily reflects the
sale of certain nonperforming loans partially offset by the migration of other
loans to lower credit ratings. The increase from the prior year primarily
reflects rating changes on certain other loans, with the most significant
changes arising from loans to commercial clients that have filed for protection
under Chapter 11 bankruptcy laws over the past year.

Total Reserve. Management's evaluation of the factors above resulted in a
reserve for credit losses of $159.7 million at June 30, 2001 compared to $167.9
million at March 31, 2001. The reserve as a percentage of total loans decreased
to .88% at June 30, 2001 from .94% at March 31, 2001.

Provision. The provision for credit losses was $11.5 million during the second
quarter of 2001, compared to $10.0 million in the prior year quarter. The
provision for the second quarter of 2001 was affected by the factors described
above, including the $6.5 million provision related to the sale of $44.5 million
in nonperforming loans. The provision for the comparable period in 2000 was
affected by the rapid deterioration of one commercial loan that was sold during
the second quarter of 2000, resulting in a charge-off of $5.4 million against
the reserve.

MARKET RISK MANAGEMENT

As described in the 2000 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.
