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 March 31, 2001 and 2000 have not been audited by
     independent 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 March 31, 2001, other domestic and international loans included $1.0 billion
of overnight trust-related advances, primarily in connection with next day
security settlements, compared with $1.4 billion at December 31, 2000 and $1.2
billion at March 31, 2000.

At March 31, 2001, nonperforming loans totaled $111.1 million. Included in this
amount were loans with a recorded investment of $107.7 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 $10.6 million had no portion of the reserve for credit losses allocated
to them while impaired loans totaling $97.1 million had an allocated reserve of
$29.0 million. For the first quarter of 2001, the total recorded investment in
impaired loans averaged $82.5 million. There was no interest income recorded on
impaired loans for the quarter ended March 31, 2001.

At March 31, 2000, nonperforming loans totaled $56.5 million and included $55.0
million of impaired loans. Of these impaired loans, $7.1 million had no portion
of the reserve for credit losses allocated to them while $47.9 million had an
allocated reserve of $19.0 million. Total recorded investment in impaired loans
for the first quarter of 2000 averaged $56.2 million with $26 thousand of
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.

10.  Accounting Standards Pronouncements - In June 1998, the Financial
Accounting Standards Board (FASB) issued Statement of Financial Accounting
Standards (SFAS) No. 133, "Accounting for Derivative Instruments and Hedging
Activities." SFAS No. 133 establishes accounting and reporting standards
requiring that every derivative instrument (including certain derivative
instruments embedded in other contracts) be recorded on the balance sheet as
either an asset or liability measured at its fair value. SFAS No. 133 requires
that changes in the derivative's fair value be recognized currently in earnings
unless hedge accounting criteria are met. Accounting for qualifying hedges
allows a derivative's gains and losses to offset related results on the hedged
item in the income statement, and requires that a company formally document,
designate, and assess the effectiveness of transactions that receive hedge
accounting.

In July 1999, the FASB issued SFAS No. 137 which amended SFAS No. 133 by
deferring the effective date by one year to January 1, 2001 from January 1, 2000
for calendar year-end entities. Northern Trust adopted the new statement on
January 1, 2001.

In June 2000, the FASB issued SFAS No. 138, which further amended SFAS No. 133
by addressing a limited number of issues that have caused implementation
difficulties. The accounting requirements of these statements are complex and
the FASB continues to receive and respond to interpretation requests. The FASB's
response to these interpretation requests may have an impact on Northern Trust's
current and future hedge strategies. Based on the existing guidance, the January
1, 2001 adoption of these statements increased earnings by approximately $10
thousand and reduced other comprehensive income, a component of capital, by $.2
million. It is estimated that the entire January 1, 2001 balance in other
comprehensive income will be reclassified into earnings within twelve months.

In addition, Northern Trust concluded that certain previous hedge strategies
used to manage fixed interest rate risk in its loan portfolio would not qualify
for the special hedge accounting treatment allowed by SFAS No. 133. Accordingly,
management implemented alternative strategies for managing interest rate risk
which included the termination and run-off of certain swap contracts used to
hedge fixed rate loans and increased utilization of longer-term fixed rate
liabilities. Management estimates that utilization of these alternative
strategies to manage interest rate risk will reduce net interest income by
approximately $750 thousand on an annualized basis.

In September 2000, the FASB issued SFAS No. 140, "Accounting for Transfers and
Servicing of Financial Assets and Extinguishment of Liabilities." SFAS No. 140
replaces SFAS No. 125, the previous standard of the same title. It revises the
standards for accounting for securitizations and other transfers of financial
assets and collateral and requires certain disclosures, but it retains most of
the accounting requirements of SFAS No. 125. The accounting requirements of the
Statement are effective for transactions occurring after March 31, 2001 and the
disclosure requirements of the Statement are effective for fiscal years ending
after December 15, 2000. It is not anticipated that the adoption of SFAS No. 140
will have a material effect on Northern Trust's results of operations.

11.  Business Segments

The tables on page 19, reflecting the earnings contribution of Northern Trust's
business segments for the first quarter ended March 31, 2001, are incorporated
by reference.


12.  Risk Management Instruments

Risk management instruments utilized by Northern Trust include the following
types of derivative contracts:

Foreign Exchange Contracts are agreements to exchange specific amounts of
currencies at a future date, at a specified rate of exchange. Foreign exchange
contracts are entered into primarily to meet the foreign exchange risk
management needs of clients. Foreign exchange contracts are also used for
trading purposes and asset/liability management.

Interest Rate Protection Contracts are agreements that enable clients to
transfer, modify or reduce their interest rate risk. As a seller of interest
rate protection, Northern Trust receives a fee at the outset of the agreement
and then assumes the risk of an unfavorable change in interest rates. Northern
Trust also purchases interest rate protection contracts for asset/liability
management.

Interest Rate Swap Contracts involve the exchange of fixed and floating rate
interest payment obligations without the exchange of the underlying principal
amounts.

Forward Sale Contracts represent commitments to sell a specified amount of
securities at an agreed upon date and price. Northern Trust utilizes forward
sale contracts principally in connection with its sale of mortgage loans.

The major risk associated with these instruments is that interest or foreign
exchange rates could change in an unanticipated manner, resulting in higher
interest costs or a loss in the underlying value of the instrument. These risks
are mitigated by establishing limits for risk management positions, monitoring
the level of actual positions taken against such established limits, monitoring
the level of any interest rate sensitivity gaps created by such positions, and
by using hedging techniques. When establishing position limits, market liquidity
and volatility, as well as experience in each market, are all taken into
account.

The estimated credit risk associated with these instruments relates to the
failure of the counterparty to pay based on the contractual terms of the
agreement, and is generally limited to the gross unrealized market value gains
on these instruments. The amount of credit risk will increase or decrease during
the lives of the instruments as interest or foreign exchange rates fluctuate.
This risk is controlled by limiting such activity to an approved list of
counterparties and by subjecting such activity to the same credit and quality
controls as are followed in lending and investment activities.

                                       12


Derivatives Used for Asset/Liability Management

Fair Value Hedge Designations. Northern Trust may designate certain derivatives
as hedges of specific fixed rate assets or liabilities on its balance sheet. The
risk management policy for such hedges is to reduce or eliminate the exposure to
overall changes in the value of the hedged assets or liabilities. As of March
31, 2001, one interest rate swap was designated and qualified as a hedge against
the overall change in value for a specific fixed rate commercial loan. A gain of
$149 thousand was recognized in earnings through March 31, 2001 to reflect the
extent to which the hedge was not effective in achieving an offsetting change in
the fair value of the loan. Unrealized gains and losses on such swaps are
recognized as a component of interest income or expense of the hedged item.

Cash Flow Hedge Designations. Certain derivatives may be designated as hedges
against exposure to variability in expected future cash flows attributable to
particular risks, such as fluctuations in foreign exchange or interest rates.
Northern Trust currently uses cash flow hedges to reduce or eliminate the
exposure to changes in foreign exchange rates. As of March 31, 2001, certain
forward foreign exchange contracts were designated and qualified as hedges
against changes in certain forecasted transactions denominated in foreign
currencies. A net loss of $1.4 million related to these instruments was
recognized in other comprehensive income. It is estimated that essentially all
of the net loss at March 31, 2001 will be reclassified into earnings within the
next twelve months. Reclassifications into earnings will occur in the same
periods that the hedged cash flows impact revenues or expenses. The maximum
length of time over which these hedges will exist is sixteen months. There was
no earnings impact due to hedge ineffectiveness through March 31, 2001.

Other Derivatives not Designated as Hedges. Forward foreign exchange contracts
were used to reduce exposure to fluctuations in the dollar value of capital
investments in foreign subsidiaries and from foreign currency assets and
obligations. Realized and unrealized gains and losses on such contracts are
recognized as a component of foreign exchange trading profits.


Client and Trading-Related Risk Management Instruments

Northern Trust is a party to various risk management instruments that are used
in the normal course of business to meet the risk management needs of its
clients and as part of its trading activity for its own account. Realized and
unrealized gains and losses from interest risk management instruments are
included in security commissions and trading income. Foreign exchange trading
gains and losses are recognized currently in foreign exchange trading profits.

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


FIRST QUARTER EARNINGS HIGHLIGHTS

Net income increased 12% to a record $127.2 million from the $113.3 million
earned in the first quarter of last year. Net income per common share on a
diluted basis also increased 12% to $.55 for the first quarter, up from $.49
earned a year ago. This earnings performance produced an annualized return on
average common equity (ROE) of 21.53% versus 21.70% reported last year, and an
annualized return on average assets (ROA) of 1.45% versus 1.46% in 2000.
Although revenues increased 7%, Northern Trust was able to achieve earnings
growth of 12% by aggressively managing expenses, which rose only 5%, resulting
in the attainment of positive operating leverage. Trust fee growth of 7%,
complemented by an 11% increase in treasury management revenues and a 7%
increase in net interest income, combined to increase total revenues to a record
$551.5 million (stated on a fully taxable equivalent basis).

The 12% earnings per share growth exceeded Northern Trust's minimum goal of 10%,
and the ROE surpassed 20% for the sixteenth consecutive quarter. The
productivity ratio of 161% also exceeded the corporate goal of 160%.

Noninterest Income

Noninterest income increased 7% and totaled $389.5 million for the quarter,
accounting for 71% of total taxable equivalent revenue. Trust fees of $305.2
million increased 7% or $19.2 million over the like period of 2000 and
represented 78% of noninterest income and 55% of total taxable equivalent
revenue. Trust fee growth resulted from strong new business, offset in part by
lower equity markets. Trust fees in the quarter attributable to 2000
acquisitions totaled $3.3 million. Trust assets under administration grew to
$1.65 trillion, up 3% since March 31, 2000, but declined 2% since December 31,
2000 as a result of lower equity markets. Trust assets under the management of
Northern Trust grew $13.5 billion since last year to $336.6 billion and were
down just $1.4 billion from December 31, 2000.

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
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.

Noninterest Income (continued)

Trust fees from Personal Financial Services (PFS) increased 7% from the prior
year level of $145.5 million and totaled $156.1 million for the first quarter.
This performance reflects continued strong new business throughout Northern
Trust's national PFS network, offset in part by lower equity markets. All twelve
states in the PFS network recorded increases in trust fees, with the largest
states ranging from 1% in Florida to 14% in Texas. The Wealth Management Group
continued to show strong performance with trust fees increasing 11%, and now
administers $59.6 billion for significant family asset pools worldwide, up 5%
from March 31, 2000. Total personal trust assets under administration totaled
$160.0 billion at March 31, 2001, compared to $162.1 billion at March 31, 2000
and $168.8 billion at December 31, 2000. Of these assets under administration,
$93.3 billion is managed by Northern Trust, compared to $97.3 billion one year
ago and $98.1 billion at December 31, 2000. At March 31, 2001, approximately 53%
of the personal trust assets under administration and 49% of assets under
management were invested in equity securities. Net new recurring PFS trust
business sold during the first quarter totaled approximately $15 million in
annualized fees.

Northern Trust continued the expansion of the PFS network of offices with the
April 2001 opening of a full service office in Weston, Florida. Northern Trust
now has Personal Financial Services offices in 82 locations in twelve states, up
from 76 offices in ten states at the end of last year's first quarter.

Trust fees from Corporate & Institutional Services (C&IS) in the quarter
increased 6% and totaled $149.1 million compared to $140.5 million in the year-
ago quarter, reflecting strong new business growth, offset in part by lower
equity markets. 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. Custody fees increased to $50.7
million, up 16%, reflecting strong new business and fees associated with the May
2000 acquisition of Northern Trust (Ireland) Limited. Fees from asset management
increased 3% to $43.8 million. Securities lending fees of $29.9 million were
$2.3 million below the year-ago quarter, which benefited from the carryover
effect of higher Year 2000-related spreads. Strong new business results
increased fees generated by Northern Trust Retirement Consulting, L.L.C., to
$15.3 million, up 17% from last year's first quarter.

Total C&IS trust assets under administration totaled $1.49 trillion at March 31,
2001, compared to $1.44 trillion at March 31, 2000 and $1.51 trillion at
December 31, 2000. Of the C&IS trust assets under administration, $243.3 billion
is managed by Northern Trust, up 8% from March 31, 2000 and 1% higher than at
year-end. At March 31, 2001, approximately 37% of assets under administration
and 25% of assets under management were invested in domestic equity securities.
Trust assets under administration included approximately $418 billion of global
custody assets. Net new recurring C&IS trust business sold during the quarter
totaled approximately $19 million in annualized fees.

Foreign exchange trading profits were $34.9 million for the quarter, up 3% from
the first quarter of 2000. The current year quarter benefited from market
volatility in the yen and a higher level of client transaction volume.

                                       15


Noninterest Income (continued)

Total treasury management revenues, which include both fees and the computed
value of compensating deposit balances, totaled $28.7 million, up 11% from last
year's first quarter, due to new business and higher transaction volumes from
existing clients. The fee portion of these revenues accrued in the quarter was
$20.1 million, up 18% from $17.1 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.

Revenues from security commissions and trading income totaled $9.6 million,
unchanged from the first quarter of 2000. Other operating income was $19.7
million for the first quarter compared with $15.7 million in the same period of
last year. The increase in other operating income resulted primarily from higher
trust deposit-related revenues and loan service fees.

Net Interest Income

Net interest income for the quarter totaled a record $148.1 million, 6% higher
than the $139.4 million reported in the first 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 a record $162.0 million, up 7% from the $150.8 million
reported in the first quarter of 2000. The increase in net interest income
reflects 14% growth in average earning asset levels and a 10% increase in
noninterest-related funding sources, primarily demand deposits and equity. The
net interest margin narrowed to 2.05% versus 2.16% reported in the year-ago
quarter, but improved from 1.96% in the fourth quarter of 2000. The decrease
from a year ago is due primarily to the increase in short-term, lower-margin
federal agency securities and a greater reliance on interest-related funding
sources. The improvement from the fourth quarter reflects the benefit of lower
interest rates, growth in equity and higher loan volume.

Earning assets for the first quarter averaged $32.1 billion, up 14% from the
$28.1 billion average for the same quarter of 2000. The $4.0 billion growth in
average earning assets was comprised of a $2.1 billion or 14% increase in loans
and leases and a 23% or $1.9 billion increase in securities. Money market assets
averaged $4.5 billion for the quarter, unchanged from last year.

The loan growth was concentrated predominantly in the domestic portfolio, which
increased $2.0 billion to average $17.0 billion, while international loans
increased by $138 million to $721 million from a year ago. Reflecting strong
growth in lending to Wealth Management and private banking clients, personal
loans increased $554 million or 33% to average $2.3 billion on average for the
quarter. Residential mortgage loans, which represent 39% of the total average
loan portfolio, increased $559 million or 9% to average $6.8 billion for the
quarter. Commercial and industrial loans increased 9% to average $5.0 billion
compared to $4.6 billion in last year's first quarter, while lease financing
increased 49% to average $1.0 billion.

                                       16


Net Interest Income (continued)

Funding for the growth in earning assets came from several sources. Total
interest-related deposits averaged $17.9 billion, up 11% or $1.8 billion from
the first quarter of 2000. This growth was concentrated primarily in foreign
office time deposits, up $775 million as a result of increased global custody
activity, non-personal time deposits, up $504 million, and savings, money market
deposits and savings certificates, up $532 million. Other interest-related funds
averaged $9.3 billion, up $1.7 billion or 23% compared to a year ago, due
predominantly to higher levels of borrowings from the Federal Home Loan Bank and
securities sold under agreements to repurchase. Partially offsetting these
increases were lower levels of federal funds purchased. 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
10% to average $4.9 billion due to growth in common stockholders' equity
resulting from retained earnings, and to higher levels of demand deposits.

Provision for Credit Losses

The provision for credit losses was $5.0 million in the first quarter compared
to $4.0 million for the same quarter last year and $5.0 million in the fourth
quarter of 2000. For a discussion of the provision and reserve for credit
losses, refer to the Asset Quality section beginning on page 22.

Noninterest Expenses

Noninterest expenses totaled $341.6 million for the quarter, an increase of 5%
or $15.5 million from the $326.1 million in the year-ago quarter. Expense growth
has been reduced from the rate experienced in recent quarters partially as a
result of initiatives implemented by management to reduce certain discretionary
expenses. These initiatives include closely monitoring staffing 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 resulted in a $5.7 million expense savings in the quarter when
compared to programs in place prior to this initiative. Approximately two-thirds
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), business promotion, office expansion, and
operating costs relating to the significant growth in transaction volumes.
Noninterest expenses resulting from the two second quarter 2000 acquisitions
totaled $3.9 million in the current quarter.

Compensation and employee benefits, which represent approximately 60% of total
noninterest expenses, increased to $204.2 million from $194.0 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 the significant increase in
the price of Northern Trust Corporation common stock during that quarter.
Current quarter performance-based

                                       17


Noninterest Expenses (continued)

compensation levels reflect the impact of slower revenue growth, lower
investment portfolio performance and the modifications made to incentive plans.
Staff levels increased from one year ago to support growth initiatives and
strong new business in both PFS and C&IS. Staff on a full-time equivalent basis
at March 31, 2001 totaled 9,537, up 837 or 10% from March 31, 2000. Since
December 31, 2000, staff has increased by only 71 positions, or less than 1%.

Net occupancy expense totaled $24.7 million, up 19% from $20.8 million in the
first quarter of 2000, due primarily to the opening of additional 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, building depreciation and
amortization expense of leasehold improvements.

Equipment expense, comprised of depreciation, rental and maintenance costs,
totaled $21.2 million, up 18% from the $17.9 million reported in the first
quarter of 2000. The increases were primarily in depreciation of computer
hardware and office furniture, higher maintenance costs for computers and
equipment, and increased costs for data line leases.

Other operating expenses in the quarter totaled $91.5 million compared to $93.4
million last year. The decline in other operating expenses reflect the net
impact of several factors. Among other things, expenses were reduced as a result
of lower stock-related director compensation, a decrease in subcustodian and
sub-advisor costs, and a reduction in charges associated with processing errors
incurred in servicing and managing financial assets and performing banking
activities. These lower expenses more than offset higher costs associated with
continued investment in technology, 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 $63.8 million for the first quarter compared
with $58.4 million in the year-ago quarter.  The higher tax provision in 2001
resulted primarily from the growth in taxable earnings for federal income tax
purposes.  The effective tax rate for the first quarter was 33.4% compared to
34.0% for the first quarter of 2000.

Corporate and Institutional Services

C&IS net income for the quarter totaled $57.2 million, virtually unchanged from
the first quarter of 2000.  Noninterest income increased 7% to $214.3 million in
the first quarter of 2001 from $200.5 million in last year's first quarter.
Trust fees, reflecting strong new business growth, offset in part by lower
equity markets, increased 6% to $149.1 million in the current quarter compared
to $140.5 million in the year-ago quarter.  Other income was $65.2 million, up
9% from $60.0 million in last year's first quarter.  Approximately one-third of
the increase in other operating income was due to higher fees accrued 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.  The remainder of the increase in other
income was due primarily to higher trust deposit-related revenues and loan
service fees.

Net interest income after the provision for credit losses, stated on a FTE
basis, increased 11% to $46.5 million in the current quarter, from $42.1 million
in last year's first quarter.   Contributing to the improvement was a 17%
increase in average earning assets, combined with a 12% increase in noninterest-
related funds. The net interest margin declined from 1.43% last year to 1.34% in
the current quarter.

Noninterest expenses increased 12% to $167.3 million in the current quarter due
primarily to staff growth, merit increases, higher occupancy costs and expense
allocations for product and operations support.

                                       19


Personal Financial Services


PFS net income for the quarter was $68.0 million, virtually unchanged from a
year ago.  Noninterest income increased 7% to $174.1 million in the current
quarter from $162.8 million in last year's first quarter.  The increase was due
primarily to a 7% increase in trust fees, which totaled $156.1 million in the
current quarter, resulting from strong new business throughout Northern Trust's
national PFS network, offset in part by lower equity markets.  Other income
increased 4% from $17.3 million in last year's first quarter to $18.0 million in
the current quarter, due primarily to a 23% increase in treasury management fees
and higher loan-related and letter of credit fees.

Net interest income after the provision for credit losses, stated on a FTE
basis, increased 4% to $106.8 million in the current quarter.  The increase was
due primarily to a $1.6 billion or 14% increase in average loan volume, offset
in part by a reduction in the net interest margin from 3.34% last year to 3.04%
in 2001.

Noninterest expenses increased 10% to $169.9 million in the current quarter from
$154.6 million in last year's first quarter.  Approximately $3.0 million or 20%
of the total increase related to salaries and employee benefits, driven by staff
growth and merit increases.  An additional $11.1 million of the overall increase
resulted from higher expense allocations for product and operations support.  In
addition, occupancy costs were $.8 million or 11% higher as a result of opening
new PFS offices and the expansion of existing locations.

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 portfolio of interest rate risk management instruments. It is also
responsible for the investment portfolios of the Corporation and the Bank.
"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 up slightly from a year ago resulting primarily from the
impact of falling interest rates in 2001.  Noninterest expenses totaled $4.4
million for the quarter compared with $22.6 million in last year's first
quarter.  Approximately 60% of the decline in other operating expenses relates
to lower accruals for certain corporate-based incentive plans for officers and
directors, which were impacted by changes in Northern Trust Corporation's stock
price and slower revenue growth.  In addition, the prior year quarter included
accruals for incentive and other expenses associated with the earlier than
anticipated retirement of certain Bank officers.  Treasury and other expenses
were also 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.

BALANCE SHEET

Total assets at March 31, 2001 were $38.2 billion and averaged $35.7 billion for
the first quarter, up 14% from last year's average of $31.3 billion.  Due to
continued strong credit demand, loans and leases grew to $17.9 billion at March
31, 2001 and averaged $17.7 billion for the quarter.  This compares with $16.5
billion in total loans and leases at March 31, 2000 and $15.6 billion on average
for the first quarter of last year.  Securities totaled $12.7 billion at March
31, 2001 and averaged $9.9 billion for the first quarter, compared to $8.8
billion at March 31, 2000 and $8.0 billion on average in the first quarter of
2000.  The increase was primarily in short-term federal agency securities. Money
market assets totaled $3.9 billion at March 31, 2001 and averaged $4.5 billion
in the first quarter, unchanged 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 $2.45 billion at March 31, 2001 and averaged $2.37 billion
for the quarter, up 14% from the $2.08 billion average in last year's first
quarter.  Total stockholders' equity averaged $2.49 billion compared with $2.20
billion in the first quarter of 2000.

During the quarter, the Corporation acquired a total of 463,395 shares at a cost
of $34.4 million.  An additional 6.7 million shares may be purchased after March
31, 2001 under the current stock buyback program.

Northern Trust's risk-based capital ratios remained strong at 10.1% for tier 1
capital and 13.7% for total capital at March 31, 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 first quarter
average assets) of 7.3% at March 31, 2001, also exceeded the minimum regulatory
requirement of 3%.  The Bank's risk-based capital ratios at March 31, 2001 were
8.6% for tier 1 capital, 12.3% for total capital and 6.2% for the leverage
ratio.  Each of Northern Trust's other subsidiary banks had a ratio of 10.3% or
higher for tier 1 capital, 11.2% for total risk-based capital, and 6.7% for the
leverage ratio.

ASSET QUALITY

Nonperforming assets consist of nonaccrual loans and other real estate owned
(OREO). Nonperforming assets at March 31, 2001 totaled $112.7 million, compared
with $78.5 million at December 31, 2000 and $58.6 million at March 31, 2000.
Domestic nonaccrual loans and leases, consisting primarily of commercial loans,
totaled $111.1 million, or .65% of total domestic loans and leases at March 31,
2001.  At December 31, 2000 and March 31, 2000, domestic nonaccrual loans and
leases totaled $76.3 million and $56.5 million, respectively. The increase
during the quarter primarily reflects the impact of one large commercial loan to
a manufacturing company that filed for Chapter 11 reorganization at the
beginning of April 2001.

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, 2001 and
March 31, 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 at March 31, 2001, December 31, 2000 and March 31, 2000.

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


Specific Reserve.  At March 31, 2001, the specific component of the reserve
stood at $29.0 million, compared to $24.3 million at December 31, 2000 and $19.0
million at March 31, 2000. The $4.7 million increase from year-end 2000
primarily relates to the loss estimated on a large commercial loan to a
manufacturing company that filed for Chapter 11 reorganization at the beginning
of April 2001.

Allocated Inherent Reserve.  The allocated inherent portion of the reserve
increased by $1.5 million during the quarter to $114.0 million at March 31,
2001, primarily reflecting the impact of lowering the credit ratings on several
commercial loans during the quarter. This increase was partially offset by a
reduction in reserves allocated to off-balance sheet instruments, as certain
loss factors were lowered to reflect current exposure in unused commercial loan
commitments and standby letters of credit, while counterparty risk associated
with derivative products continued to increase.

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 $24.9 million, a decrease of
$1.2 million from December 31, 2000, reflecting management's judgment that there
have been only minor changes in the factors affecting this component of the
reserve.

                                       23


Provision and Reserve for Credit Losses (continued)

Other Factors.  During the quarter ended March 31, 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 $171 million, of which $107.7 million was
classified as impaired, up from $153 million at December 31, 2000 when $74.7
million was impaired, and $81 million at March 31, 2000 when $55.0 million was
impaired. These increases primarily reflect rating changes on certain loans,
with the most significant rating changes caused by two commercial clients that
filed for protection under Chapter 11 bankruptcy laws.

Total Reserve.  Management's evaluation of the factors above resulted in a
reserve for credit losses of $167.9 million at March 31, 2001 compared to $162.9
million at December 31, 2000. The reserve as a percentage of total loans
increased to .94% at March 31, 2001 from .90% at December 31, 2000.

Provision.  The resulting provision for credit losses was $5.0 million during
the first quarter of 2001.

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.
