At September 30, 2001, other domestic and international loans included $1.4
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 September 30, 2000.

At September 30, 2001, nonperforming loans and leases totaled $114.2 million.
Included in this amount were loans with a recorded investment of $112.8 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 $25.3 million had no portion of the reserve for credit
losses allocated to them while impaired loans totaling $87.5 million had an
allocated reserve of $20.1 million.  For the third quarter of 2001, the total
recorded investment in impaired loans averaged $107.2 million. There was $66
thousand of interest income recorded on impaired loans for the quarter ended
September 30, 2001.

At September 30, 2000, nonperforming loans and leases totaled $76.8 million and
included $75.2 million of impaired loans.  Of these impaired loans, $28.3
million had no portion of the reserve for credit losses allocated to them while
$46.9 million had an allocated reserve of $18.4 million.  Total recorded
investment in impaired loans for the third quarter of 2000 averaged $58.7
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 other intangible assets.  The provisions of this
Statement, as they relate to 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 September 30, 2001 totaled $92.2 million and is currently being amortized on
a straight-line method primarily over fifteen years.  Application of the
nonamortization provisions of the Statement is expected to reduce noninterest
expense by approximately $10.0 million annually, resulting in an increase in net
income of $8.0 million in 2002 compared to 2001.  Management has not yet
completed the initial goodwill impairment test to determine whether any
transitional impairment charge will be necessary.  Other separately identifiable
acquired intangible assets will continue to be amortized over their estimated
useful life.  At September 30, 2001, acquired intangible assets totaled $36.8
million and amortization for the first nine months of the year amounted to $4.9
million.

In August 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or
Disposal of Long-Lived Assets". SFAS No. 144 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 will adopt
the requirements of this Statement at the beginning of 2002.  It is not
anticipated that the adoption of SFAS No. 144 will have a material effect on
Northern Trust's results of operations.

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


THIRD QUARTER EARNINGS HIGHLIGHTS

Net income increased 3% to $126.6 million from the $123.3 million earned in the
third quarter of last year.  Net income per common share on a diluted basis
increased 4% to $.55 for the third quarter, up from $.53 earned a year ago.
This earnings performance produced an annualized return on average common equity
(ROE) of 19.63% versus 22.12% reported last year, and an annualized return on
average assets (ROA) of 1.43% versus 1.42% in 2000.  While total revenues in the
quarter were essentially flat from last year, management of expenses was
particularly effective, resulting in positive operating leverage and a
productivity ratio of 160%.


Noninterest Income

Noninterest income totaled $389.8 million for the quarter, accounting for 71% of
total taxable equivalent revenue.  Trust fees were essentially unchanged at
$304.3 million in the quarter, compared to $304.7 million in the third quarter
of last year and represented 55% of total taxable equivalent revenue.  The flat
trust fee performance resulted from sharply lower equity markets, offset by new
business. New business sold remained  strong in this difficult environment.  As
a result of this new business, trust assets under administration declined only
6% to $1.58 trillion since September 2000, despite the significant declines in
equity markets, as evidenced by the 28% decline in the S&P equity index during
this period.  Trust assets under the management of Northern Trust declined 3%
since last year and totaled $327.5 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 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.

                                       12


Noninterest Income (continued)

Trust fees from Personal Financial Services (PFS) in the quarter totaled $153.5
million, compared to $158.7 million in the year-ago quarter.  The decline in PFS
trust fees resulted from sharply lower equity markets, partially offset by new
business throughout Northern Trust's national PFS network.  Northern Trust's
network of Personal Financial Services offices 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 $149.8 billion at September
30, 2001, and reflect the transfer of $3.0 billion in assets to Corporate &
Institutional Services (C&IS).  This  compares to $171.2 billion at September
30, 2000. Of the total assets under administration, $89.8 billion is managed by
Northern Trust, compared to $100.1 billion one year ago.  At September 30, 2001,
approximately 50% of the personal trust assets under administration and 46% of
assets under management were invested in domestic equity securities.  Net new
recurring PFS trust business sold in the first nine months totaled approximately
$47 million in annualized fees.

Trust fees from C&IS in the quarter increased 3% to $150.8 million, compared to
$146.0 million in the year-ago quarter.   Securities lending fees increased 8%
to $29.3 million and were the principal contributor to the overall increase. The
securities lending growth reflected higher volumes, as well as increased spreads
earned on the investment of collateral.   Custody fees increased to $51.2
million, up 4%, largely driven by new global custody business.   Fees from asset
management totaled $46.2 million, up slightly from the $46.0 million in the
year-ago quarter, which included $3.4 million of performance-based fees compared
to $.7 million in the current quarter.  Northern Trust Retirement Consulting,
L.L.C. recorded fees of $14.2 million, essentially unchanged from last year's
third quarter.

C&IS trust assets under administration totaled $1.43 trillion at September 30,
2001, compared to $1.52 trillion at September 30, 2000.  Of the C&IS trust
assets under administration, $237.7 billion is managed by Northern Trust, down
slightly from September 30, 2000.  At September 30, 2001, approximately 35% of
assets under administration and 25% of assets under management were invested in
domestic equity securities.  Trust assets under administration included $424.9
billion of global custody assets, up 12% from a year ago.  Net new recurring
C&IS trust business sold in the first nine months totaled approximately $57
million in annualized fees.

Foreign exchange trading profits were $37.2 million for the quarter, compared to
$37.6 million in the third quarter of 2000.  The current quarter reflects
continued volatility in major currencies and transaction flows associated with
global custody assets.

Treasury management revenues, which include both fees and the computed value of
compensating deposit balances, totaled $28.6 million, up 5% 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 $21.0 million, up
16% from $18.1 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.

                                       13


Noninterest Income (continued)

Revenues from security commissions and trading income totaled $8.1 million,
essentially unchanged from last year.  Other operating income was $19.2 million
for the third quarter compared with $23.5 million in the same period of last
year.  Included in the prior year results was $2.5 million in nonrecurring
income from an asset exchange.  The remainder of the change in other operating
income primarily reflects lower levels of trust deposit-related revenues.

Net Interest Income

Net interest income for the quarter totaled $149.0 million, 4% higher than the
$142.8 million reported in the third 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 $161.6 million, up 3% from $157.1 million reported in the third quarter of
2000. Total average earning assets of $31.4 billion were unchanged from last
year's third quarter, but the net interest margin improved to 2.05% from 1.99%.
The net interest margin benefited from loan growth of 6% to $17.9 billion and
the favorable impact of lower short-term funding costs during the quarter. The
Federal Reserve Open Market Committee reduced the federal funds rate target
twice during the third quarter to 3.00%.  This compares to a rate of 6.50% at
the start of 2001.  Other favorable factors included a 6% increase in
noninterest-related funds and a 6% increase in retail savings deposits.

Earning assets for the third quarter averaged $31.4 billion, unchanged from last
year's third quarter.  The $1.1 billion growth in average loans and the $2.0
billion increase in money market assets were offset by a 29% decline in the
securities portfolio to average $7.7 billion.

The loan growth was concentrated predominantly in the domestic portfolio, which
increased $1.0 billion to average $17.1 billion, while international loans
increased by $88 million to $783 million from a year ago.  Residential mortgage
loans, which represent 40% of the total average loan portfolio, increased $633
million or 10% to average $7.2 billion for the quarter.  The lease portfolio
grew $334 million or 44%, and averaged $1.1 billion for the quarter.
Commercial and industrial loans averaged $4.9 billion, unchanged from a year
ago.

                                       14


Net Interest Income (continued)

Funding for the growth in earning assets came from several sources. Total
interest-related deposits averaged $17.8 billion, up 10% or $1.6 billion from
the third quarter of 2000.  This growth was concentrated primarily in savings
and money market deposits, up $.6 billion, and foreign office time deposits, up
$1.2 billion as a result of increased global custody activity. Other interest-
related funds averaged $8.4 billion in the quarter compared to $10.3 billion in
last year's third quarter.  The decline in other interest-related funds was due
primarily to lower levels of treasury tax deposit balances and term federal
funds sold.  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 6% to average $5.1 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 $5.0 million in the third quarter, unchanged
from the same quarter last year and down from $11.5 million recorded in the
second quarter of 2001.  The second quarter included a provision related to
sales of nonperforming loans.  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 $343.6 million for the quarter, essentially
unchanged from $344.9 million in the year-ago quarter. Expenses continue to be
closely monitored through various initiatives implemented by management
including 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 earlier
in the year, resulted in a $6.1 million expense savings in the current quarter
when compared to programs in place prior to this initiative.

Compensation and employee benefits, represented approximately 59% of total
noninterest expenses and totaled $204.2 million, down 1% from a year ago.  Staff
growth and salary increases were more than offset by lower performance-based
pay.  Performance-based pay in the prior year quarter was impacted by strong new
business, excellent investment management performance and record net income.
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 September 30, 2001 totaled
9,353 and reflects the reduction of staff resulting from the previously
announced formation of a joint venture with Fiserv, Inc., to provide receivables
management services.  The expenses related to this service are now a component
of other operating expenses.  After adjusting for the impact of this venture,
staff levels have increased 4% since September 30, 2000 and 2% since December
31, 2000.

                                       15


Noninterest Expenses (continued)

Net occupancy expense totaled $25.8 million, up 19% from $21.8 million in the
third 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 $20.8 million, up 15% from the $18.1 million reported in the third
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 $92.8 million compared to $97.7
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.  Other operating expenses also benefited from
lower stock-related directors compensation due to the decline in the stock price
of Northern Trust Corporation from the end of the second quarter.  These lower
expenses were partially offset by higher costs associated with continued
investment in technology, expansion of the PFS office network, other
expenditures to support business growth and payments made to Fiserv, Inc. for
receivables management services.  The following table shows the components of
other operating expenses.

Provision for Income Taxes

The provision for income taxes was $63.6 million for the third quarter compared
with $61.5 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 third quarter was
33.4% compared to 33.3% for the third quarter of 2000.

Corporate and Institutional Services

C&IS net income for the quarter totaled $60.9 million, down 5% from the third
quarter of 2000.  Noninterest income increased 3% to $218.6 million in the third
quarter of 2001 from $212.5 million in last year's third quarter.  Trust fees
increased 3% to $150.8 million in the current quarter compared to $146.0 million
in the year-ago quarter, due primarily to an 8% increase in securities lending
fees.  Other income was $67.8 million, up 2% from $66.5 million in last year's
third quarter.  The increase reflects a 14% or $2.2 million increase in 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 last year's third quarter.

Net interest income after the provision for credit losses, stated on a FTE
basis, was $46.9 million, down 5% from $49.3 million in last year's third
quarter.  The impact of the $1.9 billion increase in average earning assets was
more than offset by a decline in the net interest margin to 1.23% from 1.42% in
the prior year quarter and a $1.6 million increase in the provision for possible
credit losses.

Noninterest expenses increased 6% to $165.9 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.

Personal Financial Services

PFS net income for the quarter was $66.9 million, essentially unchanged from
$66.7 million reported a year ago. Noninterest income was $170.2 million in the
current quarter compared to $177.1 million in last year's third quarter. The
decrease was due primarily to lower trust fees, which totaled $153.5 million in
the current quarter, resulting from sharply lower equity markets, partially
offset by new business throughout Northern Trust's national PFS network. Other
income totaled $16.7 million in the current quarter, compared with $18.4 million
in the prior year, which included $2.5 million of nonrecurring income from an
asset exchange.

Net interest income after the provision for credit losses, stated on a FTE
basis, increased 7% to $106.5 million in the current quarter.  The increase was
due primarily to a $1.1 billion or 9% increase in average loan volume, offset in
part by a reduction in the net interest margin to 2.99% from 3.09% last year.

                                       18


Personal Financial Services (continued)

Noninterest expenses decreased slightly to $167.7 million in the current quarter
from $168.0 million in last year's third quarter. Expense allocations for
product and operations support increased 11% or $6.3 million in the quarter.
Occupancy costs were $1.1 million or 14% higher as a result of opening new PFS
offices and the expansion of existing locations. Salaries and employee benefits
declined 1% as the effects of staff growth and merit increases were more than
offset by lower performance-based pay. In addition, business development
expenses and operating costs associated with processing errors incurred in
servicing and managing financial assets were down from a year ago.

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 third quarter was up slightly from a year ago
resulting primarily from the impact of falling interest rates in 2001.
Noninterest expenses totaled $10.0 million for the quarter compared with $19.8
million in last year's third quarter.  The decline in operating expenses relates
to lower accruals for certain corporate-based incentive plans.  In addition,
expenses were reduced due to lower stock-related directors compensation
resulting from the decline in the price of Northern Trust Corporation common
stock from the end of the second quarter.

NINE-MONTH EARNINGS HIGHLIGHTS

Net income per common share on a diluted basis increased 8% to $1.66 for the
nine-month period ended September 30, 2001, up from $1.54 last year.  Net income
increased 7% to $385.1 million from $359.6 million in the year-ago period.  The
ROE was 20.72% compared to 22.21% last year, while the ROA was unchanged at
1.44%.  The productivity ratio improved to 162% from 159% last year.

Total revenues, stated on a fully taxable equivalent basis, increased 4% from
2000 levels.  Trust fees totaled $927.2 million, up 3% from $896.3 million last
year.  Foreign exchange trading profits totaled $112.6 million, down 1% from
last year's strong performance.  Treasury management revenues from both fees and
the computed value of compensating deposit balances increased 8% to $86.2
million. The fee portion of these revenues accrued in the period totaled $61.7
million, up 16% from 2000 levels.  Other operating income totaled $65.9 million
in the period compared with $57.9 million in 2000.  The increase from last year
is comprised of the $9.2 million nonrecurring gain recorded in this year's
second quarter, in addition to higher loan and trust deposit-related fees.  The
third quarter of 2000 included $2.5 million of nonrecurring income from an asset
exchange.

Net interest income, stated on a FTE basis, totaled $484.3 million, up 5% from
$462.0 million reported last year.  The $21.5 million provision for credit
losses was $2.5 million higher than the $19.0 million required in the same
period last year.  Noninterest expenses were up 3% and totaled $1.04 billion
compared to $1.01 billion a year ago.

                                       19


BALANCE SHEET

Total assets at September 30, 2001 were $35.1 billion and also averaged $35.1
billion for the third quarter, up 2% from last year's average of $34.5 billion.
Due to continued credit demand, loans and leases grew to $18.8 billion at
September 30, 2001 and averaged $17.9 billion for the quarter.  This compares
with $17.7 billion in total loans and leases at September 30, 2000 and $16.8
billion on average for the third quarter of last year.  Securities totaled $6.0
billion at September 30, 2001 and averaged $7.7 billion for the third quarter,
compared to $10.0 billion at September 30, 2000 and $10.8 billion on average in
the third quarter of 2000.  Money market assets totaled $6.1 billion at
September 30, 2001 and averaged $5.7 billion in the third quarter, up 54% 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 $2.61 billion at September 30, 2001 and averaged $2.54
billion for the quarter, up 16% from the $2.19 billion average in last year's
third quarter. Total stockholders' equity averaged $2.66 billion compared with
$2.31 billion in the third quarter of 2000.

During the quarter, the Corporation acquired a total of 798,342 shares at a cost
of $47.1 million.  An additional 5.4 million shares may be purchased after
September 30, 2001 under the current stock buyback program.

Northern Trust's risk-based capital ratios remained strong at 10.6% for tier 1
capital and 13.9% for total capital at September 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 third quarter
average assets) of 7.9% at September 30, 2001, also exceeded the minimum
regulatory requirement of 3%.  The Bank's risk-based capital ratios at September
30, 2001 were 9.0% for tier 1 capital, 12.4% for total capital and 6.7% 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 7.1%
for the leverage ratio.

ASSET QUALITY

Nonperforming assets consist of nonaccrual loans and other real estate owned
(OREO). Nonperforming assets at September 30, 2001 totaled $115.8 million,
compared with $109.4 million at June 30, 2001, $78.5 million at December 31,
2000 and $78.8 million at September 30, 2000.  Domestic nonaccrual loans
consisting primarily of commercial loans, totaled $114.2 million, representing
 .65% of total domestic loans and leases at September 30, 2001.   At June 30,
2001, December 31, 2000 and September 30, 2000, domestic nonaccrual loans and
leases totaled $107.9 million, $76.3 million and $76.8 million, respectively.
The change during the third quarter from June 30, 2001 reflects further
deterioration, principally, in two middle market commercial loans, offset in
part by the partial charge-off of a commercial loan currently involved in
Chapter 11 reorganization proceedings and the repayment of another large loan
through the successful completion of a workout program.

                                       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 nine months ended September 30, 2001 and
September 30, 2000 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, in each case, at September 30, 2001, June 30, 2001,
December 31, 2000 and September 30, 2000.

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



Specific Reserve.  At September 30, 2001, the specific component of the reserve
stood at $20.1 million, compared to $23.4 million at June 30, 2001.  The $3.3
million reduction in the specific component of the reserve during the quarter
reflects, primarily, the partial charge-off of one commercial loan currently in
Chapter 11 reorganization proceedings, offset in part by deterioration in
certain middle market commercial loans.  The charge-off referred to above
totaled $5.6 million, all of which had previously been reserved for.

Allocated Inherent Reserve.  The allocated inherent portion of the reserve
increased by a net $2.8 million during the third quarter to $115.1 million at
September 30, 2001.  The change in this component of the reserve reflects
primarily the impact of the transfer of certain commercial loans to weaker
rating categories for which larger reserve provision factors are applied.  In
addition, during the quarter, management completed its periodic review of all
loss factors utilized in estimating the inherent loss in the portfolio.  As a
result of this review, the loss factors for certain credit rating categories for
commercial credits were reduced.  The loss factor adjustments reflected
management's assessment of the credit risk inherent for these categories and
historical loss experience.

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 primarily in the commercial loan 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 $22.9
million, a decrease of $1.1 million from June 30, 2001.

                                       22


Provision and Reserve for Credit Losses (continued)

Other Factors.  During the quarter ended September 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 loans in the two highest risk groupings, those rated "7" and "8"
(based on Northern Trust's internal rating scale, which closely parallels that
of the banking regulators), was $311 million of which $111.5 million was
classified as impaired, up from $149 million at June 30, 2001 when $104.7
million was classified as impaired, and up from $160 million at September 30,
2000 when $53 million was impaired.  The increase from June 30, 2001 primarily
reflects the transfer of certain loans to lower credit ratings with
approximately 44% of the increase related to one large commercial loan whose
rating has been lowered due to exposure to potential asbestos-related claims.
The increase from the prior year primarily reflects similar rating changes on
certain loans.

Total Reserve.  Management's evaluation of the factors above resulted in a total
reserve for credit losses of $158.1 million at September 30, 2001 compared to
$159.7 million at June 30, 2001.  The reserve as a percentage of total loans
stood at .84% at September 30, 2001, versus .88% at June 30, 2001.

Provision.  The provision for credit losses was $5.0 million during the third
quarter of 2001, compared to $11.5 million in the second quarter of 2001 and
$5.0 million in the prior year quarter.  The provision for the second quarter of
2001 was affected by the $6.5 million provision related to the sale of $44.5
million in nonperforming loans.


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.

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, 2000.
