                          MARSHALL & ILSLEY CORPORATION
                          Notes to Financial Statements
                         March 31, 2002 & 2001 (Unaudited)

   1.   The accompanying unaudited consolidated financial statements should be
        read in conjunction with Marshall & Ilsley Corporation's ("M&I" or
        "Corporation") 2001 Annual Report on Form 10-K.  The unaudited financial
        information included in this report reflects all adjustments (consisting
        only of normal recurring accruals) which are necessary for a fair
        statement of the financial position and results of operations as of and
        for the three months ended March 31, 2002 and 2001.  The results of
        operations for the three months ended March 31, 2002 and 2001 are not
        necessarily indicative of results to be expected for the entire year.
        Certain amounts in the 2001 consolidated financial statements and
        analyses have been reclassified to conform with the 2002 presentation.

  2.    Change in Method of Accounting

        On January 1, 2002, the Corporation adopted SFAS No. 142, GOODWILL AND
        OTHER INTANGIBLE ASSETS.  This statement addresses financial accounting
        and reporting for acquired goodwill and other intangible assets and
        supercedes APB Opinion No. 17, INTANGIBLE ASSETS.  SFAS 142 prescribes
        the accounting and reporting for intangible assets that are acquired
        individually or with a group of other assets (but not those acquired in
        a business combination) upon their acquisition.  SFAS 142 also
        prescribes how goodwill and other intangible assets should be accounted
        for after they have been initially recognized in the financial
        statements.

        SFAS 142 adopts an aggregate view of goodwill and bases the accounting
        for goodwill on the units of the combined entity into which an acquired
        entity is integrated  (those units are referred to as Reporting Units).
        A Reporting Unit is an operating segment as defined in SFAS 131 or one
        level below an operating segment.

        Goodwill and intangible assets that have indefinite useful lives will
        not be amortized under the new standard but rather will be tested
        annually for impairment.  Intangible assets with finite lives will
        continue to be amortized over their useful lives, but without the
        constraint of the prescribed ceilings required under APB Opinion 17.

        SFAS 142 provides specific guidance for testing goodwill and intangible
        assets that will not be amortized for impairment.  Goodwill will be
        tested for impairment at least annually using a two-step process that
        begins with an estimation of the fair value of a Reporting Unit.  The
        first step is a screen for potential impairment and the second step
        measures the amount of impairment, if any.  Intangible assets that will
        not be amortized, will be tested annually by comparing the fair values
        of the assets with their recorded amounts.

        The provisions of SFAS 142 are now being applied by the Corporation.
        Goodwill and intangible assets acquired after June 30, 2001, are subject
        immediately to the nonamortization and amortization provisions of the
        statement.  In addition, the Corporation has six months from the date
        it initially applies this standard to complete the first step of the
        transitional goodwill impairment test.  The amounts used in the
        transitional goodwill impairment test shall be measured as of January
        1, 2002.  Impairment losses for goodwill and indefinite-lived intangible
        assets that arise due to initial application of this standard (resulting
        from a transitional impairment test) would be reported as a change in
        accounting principle.

  3.    Business Combinations

        The following acquisitions, which were not considered material business
        combinations, were completed during the first quarter of 2002.

        On March 1, 2002 the Corporation acquired all of the common stock of
        Richfield State Agency, Inc. ("Richfield"), a Minnesota bank holding
        company.  Richfield had consolidated total assets of approximately $0.8
        billion at completion of the merger.  The Corporation issued 2.5 million
        common shares and paid cash of approximately $10.0 million in a tax-free
        exchange for the outstanding common stock of Richfield using the
        purchase method of accounting.  The core deposit intangible and other
        identifiable intangible assets recorded in this transaction amounted to
        $19.3 million and $0.8 million, respectively.  Initial goodwill subject
        to the completion of appraisals and valuations of the assets acquired
        and liabilities assumed, amounted to $94.6 million.

        Also, on March 1, 2002 the Corporation acquired all of the common stock
        of Century Bancshares, Inc. ("Century"), a Minnesota bank holding
        company.  Century had consolidated total assets of approximately $0.3
        billion at completion of the merger.  The Corporation issued 0.6 million
        common shares and paid cash of approximately $19.9 million in a tax-free
        exchange for the outstanding common stock of Century using the purchase
        method of accounting.  The core deposit intangible recorded in this
        transaction amounted to $6.1 million.  Initial goodwill subject to the
        completion of appraisals and valuations of the assets acquired and
        liabilities assumed, amounted to $34.1 million.

        The results of operations of the acquired entities have been included
        in the consolidated results since the dates the transactions were
        closed.

  7.    Sale of Receivables

        During the first quarter of 2002, $97.8 million of automobile loans were
        sold in securitization transactions and gains of $1.5 million were
        recognized.  Other income associated with auto securitizations in the
        current quarter amounted to $0.6 million.

        Key economic assumptions used in measuring the retained interests at the
        date of securitization resulting from securitizations completed during
        the first quarter were as follows (rate per annum):

        Prepayment speed                          25.0 %
        Weighted average life (in months)         20.8
        Expected credit losses                    0.12 %
        Residual cash flow discount rate          12.0 %
        Variable returns to transferees           Forward one month LIBOR yield

        At March 31, 2002, securitized automobile loans and other automobile
        loans managed together with them along with delinquency and credit loss
        information consisted of the following:

 10.    Derivative Financial Instruments and Hedging Activities

        TRADING INSTRUMENTS

        The Corporation enters into interest rate swaps as part of its trading
        activities which enable its customers to manage their exposures to
        interest rate risk.  The Corporation's market risk from unfavorable
        movements in interest rates is generally minimized by concurrently
        entering into offsetting positions with nearly identical notional
        values, terms and indices.

        At March 31, 2002, interest rate swaps designated as trading consisted
        of $451.1 million in notional amount of receive fixed/pay floating with
        an aggregate positive fair value of $1.0 million and $436.9 million in
        notional amount of pay fixed/receive floating with an aggregate negative
        fair value of $1.0 million.

        Interest rate swaps designated as trading are recorded at fair value.
        Gains and losses arising from changes in fair value are recorded in
        other income.

        FAIR VALUE HEDGES

        The following table presents information with respect to the
        Corporation's fair value hedges.

 11.    Segments

        Generally, the Corporation organizes its segments based on legal
        entities.  Each entity offers a variety of products and services to meet
        the needs of its customers and the particular market served.  Each
        entity has its own president and is separately managed subject to
        adherence to Corporate policies.  Discrete financial information is
        reviewed by senior management to assess performance on a monthly basis.
        Certain segments are combined and consolidated for purposes of assessing
        financial performance.

        The Corporation evaluates the profit or loss performance of its segments
        based on operating income.  Operating income is after-tax income
        excluding nonrecurring charges and charges for services from the holding
        company.  The accounting policies of the Corporation's segments are the
        same as those described in Note 1 to the Corporation's Annual Report on
        Form 10K, Item 8.  Intersegment revenues may be based on cost, current
        market prices or negotiated prices between the providers and receivers
        of services.

        Based on the way the Corporation organizes its segments and the
        requirements of Statement of Financial Accounting Standards No. 131,
        "Disclosures about Segments of an Enterprise and Related Information",
        the Corporation has determined that it has two reportable segments.

ITEM 2  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL POSITION AND
        RESULTS OF OPERATIONS

                THREE MONTHS ENDED MARCH 31, 2002 and 2001
                ------------------------------------------
Net income for the first quarter of 2002 amounted to $115.6 million compared
to $86.2 million for the same period in the prior year.  Basic and diluted
earnings per share were $1.09 and $1.05 respectively for the three months
ended March 31, 2002, compared with $.83 and $.80 respectively for the three
months ended March 31, 2001.  The return on average assets and average equity
was 1.72% and 18.04% for the quarter ended March 31, 2002 and 1.34% and
15.31% for the quarter ended March 31, 2001.

The results of operations and financial position as of and for the three
months ended March 31, 2002, include the effects of Metavante's four
acquisitions in the second, third and fourth quarters of 2001, the
Corporation's acquisitions of National City Bancorporation ("National City")
and certain Arizona branches in the third quarter of 2001 and the
acquisitions of Richfield State Agency, Inc. ("Richfield") and Century
Bancshares, Inc. ("Century") which both closed on March 1, 2002.  All
acquisitions were accounted for using the purchase method of accounting and
accordingly the results of operations and financial position are included
from the dates the transactions were closed.

Net income for the prior year quarter includes expenses associated with the
charter consolidation, the cumulative effect of adopting the accounting
standard on accounting for derivative financial instruments and hedging
activities and certain goodwill amortization and negative goodwill accretion
which ceased on January 1, 2002 as a result of adopting Statement of
Financial Accounting Standards No. 142, Goodwill and Other Intangible Assets.
The impact of these items is shown in the following table ($000's):

The following tables present a summary of each of the major elements of the
consolidated operating income statement, certain financial statistics and a
summary of the major operating income statement elements stated as a percent
of average consolidated assets converted to a fully taxable equivalent basis
(FTE) where appropriate for the current quarter and previous four quarters.
Operating income for the third and fourth quarters of 2001 excludes certain
expenses incurred in connection with acquisitions at the Corporation's
Metavante subsidiary.  Operating income for the second quarter of 2001
excludes certain losses and expenses incurred in connection with structural
changes and acquisitions at the Corporation's Metavante subsidiary, auto
lease residual value write-downs and the final charge for the charter
consolidation initiative.  Operating income for the first quarter of 2001
excludes those items previously discussed.  In addition, operating income for
the second, third and fourth quarters of 2001 exclude certain goodwill
amortization and negative goodwill accretion which ceased on January 1, 2002
as a result of adopting the new accounting standard on goodwill and other
intangible assets.  Return on tangible equity is based on operating income
before amortization of intangibles.  Amortization includes amortization of
goodwill and core deposit premiums and is net of negative goodwill accretion
and the income tax expense or benefit, if any, related to each component.
This calculation was specifically formulated by the Corporation and may not
be comparable to similarly titled measures reported by other companies.

                             NET INTEREST INCOME
                             -------------------
Net interest income for the first quarter of 2002 amounted to $240.3 million
compared to $185.8 million reported for the first quarter of 2001. Loan
growth and increased spreads on loan products, the impact of the banking
purchase acquisitions and the downward repricing of funding sources all
contributed to the $54.5 million increase in net interest income.  Factors
negatively affecting net interest income included the ongoing process of
lengthening liabilities in order to reduce future volatility in net interest
income due to interest rate movements, the cost of treasury share repurchases
and the cost of acquisitions.

Average earning assets in the first quarter of 2002 increased $1.0 billion
or 4.0% compared to the same period a year ago.  Average loans accounted for
$1.8 billion of the growth in earning assets compared to the first quarter
of last year, while average investment securities and other short-term
investments declined $0.8 billion.  The Corporation estimates that
approximately $1.7 billion of average earning asset growth was attributable
to the banking related purchase acquisitions.

Average interest bearing liabilities increased $0.4 billion or 2.2% in the
first quarter of 2002 compared to the same period in 2001.  Since the first
quarter of 2001, average interest bearing deposits decreased $1.2 billion
while average total short-term borrowings increased $0.8 billion and average
long-term borrowings increased $0.8 billion. The Corporation estimates that
approximately $1.3 billion of the growth in average interest bearing
liabilities in the three months ended March 31, 2002, was attributable to the
banking related purchase acquisitions.

Average noninterest bearing deposits increased $0.5 billion or 19.8% compared
to the same period last year. Approximately $0.3 billion of average
noninterest bearing deposits in the three months ended March 31, 2002 are
attributable to the banking related purchase acquisitions.

portfolio for the current quarter and previous four quarters are reflected

Compared with the first quarter of 2001, total consolidated average loans and
leases  increased  $1.8 billion or 10.4%.  Approximately $1.5 billion of
average total consolidated loan and lease growth in the first quarter of 2002
is attributable to acquisitions of which, approximately $0.2 billion is the
estimated impact on average loans resulting from the Richfield and Century
acquisitions which closed March 1, 2002.  Excluding the impact of
acquisitions, average commercial loans declined $0.2 billion while average
commercial real estate loans grew approximately $0.7 billion.  Portfolio
decreases in indirect auto loans and leases and student loans, tighter spread
products, were offset by growth in consumer and home equity portfolios, both
wider spread products. Approximately $0.1 billion of indirect auto loan
production was securitized and sold in the current quarter.  Excluding the
impact of acquisitions, average consumer loans grew approximately $0.2
billion.  The decline in average residential real estate loans, excluding
acquisitions, reflects the continued strategy of selling residential real
estate loan production in the secondary market.  Residential real estate
loans sold to investors amounted to $0.6 billion in the first three months
of 2002 and reflects in part the carryover of remaining inventory from year-
end 2001.  Approximately $0.3 billion of residential loans were sold in the
first quarter of the prior year.

Commercial loan growth in the quarter came from new business relationship
activities, customers continuing to acquire and some modest expansion.  Home
equity loan and line sales were strong in the first quarter and continue to
be the focus of direct mail and retail branch efforts.

Average bank issued deposits increased $1.1 billion or 7.5% in the first
quarter of 2002 compared to the first quarter of 2001.  Average bank issued
deposits associated with the acquisitions were approximately $1.3 billion of
which approximately $0.3 billion is the estimated impact on average bank
issued deposits resulting from the Richfield and Century acquisitions.
Excluding the effect of the acquisitions, noninterest bearing deposits
increased $0.3 billion and interest bearing activity accounts increased $0.8
billion of which average money market index accounts accounted for
approximately $0.5 billion of the growth.  Excluding acquisitions, average
CDs and time deposits declined $1.2 billion.  M&I's markets have experienced
some irrational pricing on single service time deposit relationships to the
extent of pricing time deposits above comparable wholesale levels which the
Corporation has elected not to pursue.  Recently the Corporation introduced
two longer-term step-up CD products that provide consumers with an increasing
rate over the term of the CD.

The growth in bank issued deposits includes both commercial and retail
banking.  In commercial banking, the focus remains on developing deeper
relationships through the sale of treasury management products and services
along with revised incentive plans focused on growing deposits.  The retail
banking strategy continues to focus on aggressively selling the right
products to meet the needs of customers and enhance the Corporation's
profitability.  Specific retail deposit initiatives include bank-at-work,
single service calling, and retention calling programs as well as an
aggressive checking promotion in the Arizona market.


Compared with the first quarter of 2001, average wholesale deposits declined
$1.7 billion and were replaced, in part, with borrowings.  The Corporation
has made greater use of wholesale funding alternatives especially
institutional CDs.  Average wholesale deposits were $0.3 billion greater in
the current quarter compared with the fourth quarter of 2001.

        rate of 35%, and excluding disallowed interest expense.
  (b)   Based on average balances excluding fair value adjustments for
        available for sale securities.

The yield on average earning assets decreased 148 basis points since the
first quarter of 2001, which had a negative impact on interest income (FTE)
of approximately $89.8 million. The increase in the volume of earning assets,
primarily loans and short term investments, increased interest income by
approximately $17.8 million compared with the first quarter of 2001.  The
cost of interest bearing deposits decreased 297 basis points from the same
quarter of the previous year which reflects rate declines.  Less reliance on
wholesale deposits together with the favorable shift in the bank issued
deposit mix as previously discussed also provided a benefit to the interest
margin.  Short-term borrowing costs decreased 245 basis points and long-term
borrowing costs decreased 131 basis points compared with the first quarter
of 2001.  The overall decrease in the cost of interest bearing liabilities
of 258 basis points decreased interest expense by approximately $128.6
million while the increase in the volume of interest bearing liabilities
increased interest expense by approximately $2.1 million.


The Corporation anticipates the net interest margin will be relatively flat
in the second quarter, with net interest income growing with internal growth
and the acquisitions.  The Corporation intends to continue to manage its
interest rate risk sensitivity by extending liabilities. The net interest
margin can vary depending on loan and deposit growth, lending spreads and
future interest rate changes.

Nonperforming assets consist of nonperforming loans and leases and other real
estate owned (OREO).

OREO is comprised of commercial and residential properties acquired in
partial or total satisfaction of problem loans and branch premises held for
sale.  At March 31, 2002, OREO acquired in satisfaction of debts amounted to
$6.5 million and branch premises held for sale amounted to $0.2 million.

Nonperforming loans and leases consist of nonaccrual, renegotiated or
restructured loans, and loans and leases that are delinquent 90 days or more
and still accruing interest.  The balance of nonperforming loans and leases
can fluctuate widely based on the timing of cash collections, renegotiations
and renewals.

Maintaining nonperforming assets at an acceptable level is important to the
ongoing success of a financial services institution.  The Corporation's
comprehensive credit review and approval process is critical to ensuring that
the amount of nonperforming assets on a long-term basis is minimized within
the overall framework of acceptable levels of credit risk.  In addition to
the negative impact on net interest income and credit losses, nonperforming
assets also increase operating costs due to the expense associated with
collection efforts.

At March 31, 2002, nonperforming loans and leases amounted to $170.3 million
or 0.84% of consolidated loans and leases of $20.3 billion, a decrease of
$3.5 million or 2.0% since December 31, 2001.  Nonaccrual loans and leases
accounted for $2.0 million of the decline.  Since year end, nonaccrual
commercial loans and leases declined $11.9 million while nonaccrual
commercial real estate and nonaccrual residential real estate increased $4.9
million and $4.7 million, respectively.  At March 31, 2002, approximately
$33.8 million of nonperforming loans are related to recent acquisitions of
which, approximately $9.4 million were attributable to the Richfield and
Century acquisitions which were completed March 1, 2002.

Net charge-offs amounted to $11.2 million or 0.23% of average loans in the
first quarter of 2002 compared with net charge-offs of $16.6 million or 0.35%
of average loans in the fourth quarter of 2001 and $5.8 million or 0.13% of
average loans in the first quarter of the prior year.

The allowance for loan and lease losses is determined using a methodology
which reserves currently for those loans and leases in which it is determined
that a loss is probable based on characteristics of the individual loan,
historical loss patterns of similar "homogeneous" loans and environmental
factors unique to each measurement date.  This reserving methodology has the
following components:

                               Specific Reserve.
                               -----------------
        The amount of specific reserves is determined through a loan-by-loan
        analysis of problem loans over a minimum size that considers expected
        future cash flows, the value of collateral and other factors that may
        impact the borrower's ability to make payments when due. Included in
        this group are those nonaccrual or renegotiated loans, which meet the
        criteria as being "impaired" under the definition in SFAS 114.  A loan
        is impaired when, based on current information and events, it is
        probable that a creditor will be unable to collect all amounts due
        according to the contractual terms of the loan agreement.  Problem
        loans also include those credits that have been internally classified
        as credits requiring management's attention due to underlying problems
        in the borrower's business or collateral concerns.  Ranges of loss are
        determined based on best-and worst-case scenarios for each loan.

                       Reserves for homogeneous loan pools.
                       ------------------------------------
        The Corporation makes a significant number of loans and leases, which
        due to their underlying similar characteristics, are assessed for loss
        as "homogeneous" pools.  Included in the homogeneous pools are loans
        and leases from the retail sector and commercial loans under a certain
        size, which have been excluded from the specific reserve allocation
        previously discussed.  The Corporation segments the pools by type of
        loan or lease and using historical loss information estimates a loss
        reserve for each pool.


                                 Special Reserve.
                                 ----------------
        The Corporation's senior lending management also allocates reserves for
        special situations which are unique to the measurement period.  These
        include environmental factors, such as economic conditions in certain
        geographical or industry segments of the portfolio, economic trends in
        the retail lending sector and peer-group loss history.  Reserves
        allocated are based  on estimates of loss that senior lending
        management has isolated based on these economic trends or conditions.
        At March 31, 2002, special reserves continue to be carried for
        exposures to the airline and travel industries, manufacturing, paper
        and allied products and dairy sectors.  While most loans in these
        categories are still performing, the Corporation continues to believe
        that these sectors were more adversely affected by the economic
        slowdown and deteriorating operating results and the potential for
        reduced collateral values, especially in a liquidation, have not
        exhibited a significant improvement since year end.

Based on the above loss estimates, senior lending and financial management
determine their best estimate of the required reserve.  Management's
evaluation of the factors described above resulted in an allowance for loan
and lease losses of $284.2 million at March 31, 2002 compared to $268.2
million at December 31, 2001 and $240.3 million at March 31, 2001.  The
resulting provisions for loan and lease losses are the amounts required to
establish the allowance for loan and lease losses to the required level after
considering charge-offs and recoveries.  Management recognizes there are
significant estimates in the process and the ultimate losses could be
significantly different from those currently estimated.


                               OTHER INCOME
                               ------------
Total other income in the first quarter of 2002 amounted to $259.0 million
compared to $246.6 million in the same period last year, an increase of $12.4
million or 5.0%.

Total data processing services revenue amounted to  $145.0 million in the
first quarter of 2002 compared to $133.0 million in the first quarter of
2001.  e-Finance solutions revenue increased $7.6 million or 28.8% compared
the first quarter of 2001, but was relatively unchanged when compared with
the fourth quarter of 2001.  Despite the purging activity of one large
customer in the fourth quarter of last year and first quarter of this year,
Internet banking accounts continued to show growth.  Active customers and
transactions processed in bill presentment and payment showed strong linked
quarter and year over year growth.  Financial technology solutions revenue,
the traditional outsourcing business, increased $7.1 million or 6.8%.  Buyout
fees, which can vary from period to period, accounted for $2.4 million of the
revenue increase.  Growth in this source of data processing services revenue
has slowed due to continued bank consolidation and a weaker economy.
However, the Corporation is beginning to experience some strengthening in the
sales pipeline.  Other revenue declined primarily due to lower professional
services revenue.  Revenue associated with acquisitions amounted to $6.3
million in the first quarter of 2002.

Item processing revenue amounted to $10.3 million in the first quarter of
2002 compared to $12.5 million in the first quarter of 2001.  During the
latter part of 2001, the Corporation sold certain item processing
relationships and also sold four Midwest item processing centers.

Trust services revenue amounted to $31.0 million in the first quarter of
2002, an increase of $1.0 million or 3.2% compared to $30.0 million in the
first quarter of 2001.  Acquisitions contributed approximately $0.6 million
to the revenue growth.  Assets under management were approximately $13.0
billion at March 31, 2002 compared to $11.8 billion at March 31, 2001 an
increase of $1.2 billion or 10.2%.  For the first time in several quarters,
managed assets experienced some slight shifting from fixed income and money
market funds into equities which generally results in higher fee income.

Service charges on deposits increased $4.7 million or 22.8% and amounted to
$25.6 million in the first quarter of 2002.  Acquisitions accounted for
approximately $0.6 million of the revenue in the first quarter of 2002. The
remainder of the increase was primarily attributable to service charges on
commercial demand accounts.


Mortgage banking revenue increased $1.6 million in the first quarter of 2002
compared to the first quarter of 2001.  Gains on the sale of mortgage loans
accounted for the majority of the increase which reflects the increased sale
activity as previously discussed.  Loan applications and closings were lower
in the first quarter 2002 than the fourth quarter of 2001 and have shifted
from predominantly refinance activity to purchase and construction.

Net investment securities activities are primarily the result of the
activities of the Corporation's Capital Markets Group and vary from period
to period.

Other income in the first quarter of 2002 amounted to $31.2 million compared
to $29.8 million in the first quarter of 2001, an increase of $1.4 million
or 4.6%.  Approximately $0.9 million of increase was attributable to the
banking acquisitions.

Total other expense for the three months ended March 31, 2002, amounted to
$313.6 million compared to $290.4 million for the three ended March 31, 2001.

Nonrecurring expenses in the first quarter of 2001 consisted of the
following:

        Single charter related expenses which are included in other expenses
        in the Consolidated Statement of Income amounted to $6.0 million in the
        first quarter of 2001.

        Included in amortization of intangibles for the three months
        ended March 31, 2001, is $4.0 million of goodwill amortization
        which ceased to be amortized under the new accounting standard
        for goodwill and intangibles which was adopted on January 1,
        2002.

Excluding these nonrecurring expenses, total other operating expense amounted
to $313.6 million in the first quarter of 2002 compared to $280.5 million in
the first quarter of 2001, an increase of $33.1 million or 11.8%.

Approximately $5.9 million of operating expenses, excluding salaries and
benefits, in the first quarter of 2002 were attributable to purchase
acquisitions which were included in M&I's operating expenses since the merger
dates.

The Corporation's nonbanking businesses, especially its Data Services segment
("Metavante"), continue to be the primary contributors to operating expense
growth.  Excluding salaries and benefits expense, Metavante operating expense
growth represents over half of all of the consolidated operating expense
growth and reflects the cost of its acquisitions as well as ongoing
investments in software, technology research and development and
infrastructure in potentially high-growth areas.

Expense control is sometimes measured in the financial services industry by
the efficiency ratio statistic.  The efficiency ratio is calculated by taking
total other expense (excluding nonrecurring charges) divided by the sum of
total other income (including Capital Markets revenue but excluding
investment securities gains or losses) and net interest income on a fully
taxable equivalent basis.  The Corporation's efficiency ratios for the three
months ended March 31, 2002 and 2001 and December 31, 2001 are:

 Excluding Intangible Amortization        49.9 %        50.3 %        51.7 %



Salaries and employee benefits expense amounted to $179.5 million in the
first quarter of 2002 compared to $167.9 million in the first quarter of
2001, an increase of $11.6 million or 6.9%.  Operating salaries and employee
benefits expense associated with banking acquisitions accounted for $2.9
million of the increase.  Increased costs in employee health plans added $1.9
million to expense and variable incentive compensation charges increased $4.1
million in the current quarter compared to the same period in the prior year.
The increase in salaries and benefits expense associated with Metavante's
acquisitions were offset by the savings arising from the structural changes
implemented in the second quarter of 2001.

Occupancy and equipment expense in the first quarter of 2002 amounted to
$45.6 million.  Approximately $2.2 million of the expense in the current
quarter was attributable to the banking and Metavante's acquisitions.
Excluding the impact of acquisitions, occupancy and equipment expense
decreased approximately $1.1 million compared to the first quarter of 2001.

Metavante's operating expense growth accounted for approximately $2.3 million
of the increase in software expenses in the first quarter of 2002 compared
to the first quarter of 2001.  During the first quarter of 2002, the
Corporation's banking segment incurred nonrecurring software charges of
approximately $1.7 million.

Acquisitions accounted for approximately $0.6 million of the quarter over
quarter increase in processing charges, supplies and printing and shipping
and handling.  The increase in professional services expense was primarily
attributable to consulting services performed for the Corporation.

Excluding the effect of the new accounting standard on accounting for
goodwill and intangibles, amortization expense increased $0.6 million and was
primarily attributable to increased core deposit intangible amortization and
other intangible amortization associated with the banking and Metavante's
acquisitions.

Other expense amounted to $35.5 million in the first quarter of 2002 compared
to $29.9 million in the first quarter of 2001.  Included in this category in
the prior year quarter were the single charter nonrecurring charges
aggregating $6.0 million as previously discussed.  Excluding these charges,
other expense amounted to $35.5 million in the current quarter compared to
$23.9 million in the first quarter of last year, an increase of $11.6
million. Losses arising from asset write-downs increased $3.9 million in the
current quarter.  Other operating expenses associated with acquisitions
accounted for approximately $1.5 million of the increase.

Other expense is affected by the capitalization of costs, net of amortization
and write-downs associated with software development and customer data
processing conversions.  Net software and conversion capitalization was $6.4
million in the first quarter of 2001 and in the current quarter amounted to
$0.9 million excluding acquisitions resulting in an increase of $5.5 million
in other expense in the first quarter of 2002 compared to the first quarter
of 2001.


                               INCOME TAXES
                               ------------
The provision for income taxes for the three months ended March 31, 2002
amounted to $54.8 million or 32.2% of pre-tax income compared to $44.3
million or 33.8% of pre-tax income for the three months ended March 31, 2001.
The decline in the effective tax rate was due to the effect of discontinuing
goodwill amortization and the recognition of income tax benefits associated
with the sale of preferred stock.


                              CAPITAL RESOURCES
                              -----------------
Shareholders' equity was $2.72 billion at March 31, 2002 compared to $2.49
billion at December 31, 2001 and $2.31 billion at March 31, 2001.

During the first quarter of 2002, the Corporation issued 3.1 million shares
of its common stock ($186.6 million) in the purchase acquisitions of
Richfield and Century.


The Corporation acquired 0.8 million shares of its common stock during the
first quarter of 2002 at an aggregate cost of $48.5 million.

The Corporation continues to have a strong capital base and its regulatory
capital ratios are significantly above the minimum requirements as shown in
the following tables.

Items 2 and 3 of this Form 10-Q, "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Quantitative and
Qualitative Disclosures about Market Risk," respectively, contain forward-
looking statements within the meaning of the safe harbor provisions of the
Private Securities Litigation Reform Act of 1995.  Such forward-looking
statements include, without limitation, statements regarding operating
activities and results.  Such statements are subject to important factors that
could cause the Corporation's actual results to differ materially than those
anticipated by the forward-looking statements.  These factors include those
referenced in the Corporation's Annual Report on Form 10-K for the period
ending December 31, 2001 or as may be described from time to time in the
Corporation's subsequent SEC filings, and such factors are incorporated herein
by reference.


ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The following updated information should be read in conjunction with the
Corporation's 2001 Annual Report on Form 10-K.  Updated information regarding
the Corporation's use of derivative financial instruments is contained in Note
10, Notes to Financial Statements contained in Item 1 herein.

Market risk arises from exposure to changes in interest rates, exchange rates,
commodity prices, and other relevant market rate or price risk.  The
Corporation faces market risk through trading and other than trading
activities. While market risk that arises from trading activities in the form
of foreign exchange and interest rate risk is immaterial to the Corporation,
market risk from other than trading activities in the form of interest rate
risk is measured and managed through a number of methods.

                           INTEREST RATE RISK
                           ------------------
The Corporation uses financial modeling techniques to identify potential
changes in income under a variety of possible interest rate scenarios.
Financial institutions, by their nature, bear interest rate and liquidity risk
as a necessary part of the business of managing financial assets and
liabilities.  The Corporation has designed strategies to limit these risks
within prudent parameters and identify appropriate risk/reward tradeoffs in the
financial structure of the balance sheet.

The financial models identify the specific cash flows, repricing timing and
embedded option characteristics of the assets and liabilities held by the
Corporation.  Policies are in place to assure that neither earnings nor fair
value at risk exceed appropriate limits.  The use of a limited array of
derivative financial instruments has allowed the Corporation to achieve the
desired balance sheet repricing structure while simultaneously meeting the
desired objectives of both its borrowing and depositing customers.

The models used include measures of the expected repricing characteristics of
administered rate (NOW, savings and money market accounts) and non-rate related
products (demand deposit accounts, other assets and other liabilities).  These
measures recognize the relative insensitivity of these accounts to changes in
market interest rates, as demonstrated through current and historical
experiences.  In addition to contractual payment information for most other
assets and liabilities, the models also include estimates of expected
prepayment characteristics for those items that are likely to materially change
their payment structures in different rate environments, including residential
mortgage products, certain commercial and commercial real estate loans and
certain mortgage-related securities.  Estimates for these sensitivities are
based on industry assessments and are substantially driven by the differential
between the contractual coupon of the item and current market rates for similar
products.

This information is incorporated into a model that allows the projection of
future income levels in several different interest rate environments.  Earnings
at risk is calculated by modeling income in an environment where rates remain
constant, and comparing this result to income in a different rate environment,
and then dividing this difference by the Corporation's budgeted operating
income before taxes for the calendar year.  Since future interest rate moves
are difficult to predict, the following table presents two potential scenarios
- a gradual increase of 100bp across the entire yield curve over the course of
a year (+25bp per quarter), and a gradual decrease of 100bp across the entire
yield curve over the course of a year (-25bp per quarter) for the balance sheet
as of the indicated dates:


                                      Impact to Annual Pretax Income as of
                                      ------------------------------------
                                            March 31,      December 31,
                                             2002              2001
                                      -----------------  -----------------
Hypothetical Change in Interest Rate
------------------------------------
                                                   
 100 basis point gradual:

  Rise in rates                             (0.9) %            (3.9) %

  Decline in rates                           0.2  %             3.1  %



These results are based solely on the modeled parallel changes in market rates,
and do not reflect the earnings sensitivity that may arise from other factors
such as changes in the shape of the yield curve, the changes in spread between
key market rates, or accounting recognition for impairment of certain
intangibles.  These results are also considered to be conservative estimates
due to the fact that they do not include any management action to mitigate
potential income variances within the simulation process.  Such action could
potentially include, but would not be limited to, adjustments to the repricing
characteristics of any on- or off-balance sheet item with regard to short-term
rate projections and current market value assessments.

Actual results will differ from simulated results due to timing, magnitude, and
frequency of interest rate changes as well as changes in market conditions and
management strategies.

Another component of interest rate risk is measuring the fair value at risk for
a given change in market interest rates.  The Corporation also uses computer
modeling techniques to determine the present value of all asset and liability
cash flows (both on- and off-balance sheet), adjusted for prepayment
expectations, using a market discount rate.  The net change in the present
value of the assets and liability cash flows in different market rate
environments is the amount of fair value at risk from those rate movements.
As of March 31, 2002 the fair value of equity at risk for a gradual 100bp shift
in rates was less than 2.0% of the market value of the Corporation.

                                EQUITY RISK
                                -----------
In addition to interest rate risk, the Corporation incurs market risk in the
form of equity risk.  M&I's Capital Markets Group invests in private, medium-
sized companies to help establish new businesses or recapitalize existing ones.
Exposure to the change in equity values for the companies that are held in
their portfolio exist, but due to the nature of the investments, cannot be
quantified within acceptable levels of precision.

As of March 31, 2002, M&I Trust Services administered $57.2 billion in assets
and directly managed a portfolio of  $13.0 billion.  Exposure exists to changes
in equity values due to the fact that fee income is partially based on equity
balances. While this exposure is present, quantification remains difficult due
to the number of other variables affecting fee income.  Interest rate changes
can also have an effect on fee income for the above stated reasons.
