                          Notes to Financial Statements
                      September 30, 2001 & 2000 (Unaudited)

   1.   The accompanying unaudited consolidated financial statements should be
        read in conjunction with Marshall & Ilsley Corporation's ("M&I" or
        "Corporation") 2000 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 and nine months ended September 30, 2001 and 2000.  The
        results of operations for the three and nine months ended September 30,
        2001 and 2000 are not necessarily indicative of results to be expected
        for the entire year.  Certain amounts in the 2000 consolidated financial
        statements and analyses have been reclassified to conform with the 2001
        presentation.

   2.   Change in Method of Accounting

        During the fourth quarter of 2000, the Corporation adopted the
        Securities and Exchange Commission's Staff Accounting Bulletin No. 101 -
        REVENUE RECOGNITION IN FINANCIAL STATEMENTS (SAB 101).  SAB 101 provides
        guidance on a variety of revenue recognition matters.  The cumulative
        effect of change in accounting principles was retroactively recorded as
        of January 1, 2000.  The financial position and results of operations
        as of and for the three and nine months ended September 30, 2000 have
        been restated to reflect application of the guidance contained in SAB
        101.  See Note 2 of the Notes to Consolidated Financial Statements of
        Item 8 of the Corporation's 2000 Annual Report on Form 10-K.

        On January 1, 2001, the Corporation adopted the Financial Accounting
        Standards Board SFAS No. 133, ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND
        HEDGING ACTIVITIES.  SFAS 133 establishes accounting and reporting
        standards requiring that every derivative instrument (including certain
        derivative instruments embedded in other contracts) be recorded in the
        balance sheet as either an asset or liability measured at its fair
        value.  The Statement requires that changes in the derivatives fair
        value be recognized currently in earnings unless specific hedge
        accounting criteria are met.  The statement requires that a company must
        formally document, designate, and assess the effectiveness of
        transactions that receive hedge accounting.  The effects of adopting
        SFAS 133 are as follows:

   3.   New Accounting Pronouncements

        In September, 2000, the FASB issued SFAS 140, ACCOUNTING FOR TRANSFERS
        AND SERVICING OF FINANCIAL ASSETS AND EXTINGUISHMENTS OF LIABILITIES.
        SFAS 140 replaces SFAS 125, ACCOUNTING FOR TRANSFERS AND SERVICING OF
        FINANCIAL ASSETS AND EXTINGUISHMENTS OF LIABILITIES.  It revises the
        standards for accounting for securitizations and other transfers of
        financial assets and collateral and requires certain disclosures, but
        it carries over most of SFAS 125's provisions without reconsideration.
        SFAS 140 is generally effective for transfers and servicing of financial
        assets and extinguishments of liabilities occurring after March 31,
        2001.  The disclosure requirements are effective for financial
        statements for fiscal years ending after December 15, 2000.  The
        adoption of SFAS 140 did not materially impact the Corporation's present
        securitization activities.

        In June, 2001, the FASB issued SFAS 141, BUSINESS COMBINATIONS.  SFAS
        141 supercedes APB Opinion No. 16, BUSINESS COMBINATIONS, and SFAS 38,
        ACCOUNTING FOR PREACQUISTION CONTINGENCIES OF PURCHASED ENTERPRISES.
        All business combinations in the scope of this Statement are to be
        accounted for using the purchase method.  This Statement carries forward
        without reconsideration portions of APB Opinion No. 16 that provide
        guidance related to the application of the purchase method.  The
        provisions of this Statement shall apply to all business combinations
        initiated after June 30, 2001 and the provisions of this Statement also
        shall apply to all business combinations accounted for by the purchase
        method for which the date of acquisition is July 1, 2001, or later.

        In June 2001, the FASB also issued SFAS 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.  It addresses how
        intangible assets that are acquired individually or with a group of
        other assets (but not those acquired in a business combination) should
        be accounted for in financial statements upon their acquisition.  This
        Statement also addresses how goodwill and other intangible assets should
        be accounted for after they have been initially recognized in the
        financial statements.  The provisions of this Statement are required to
        be applied starting with fiscal years beginning after December 15, 2001.
        Goodwill and intangible assets acquired after June 30, 2001, will be
        subject immediately to the provisions of this Statement.

        With  respect to the acquisitions of Derivion and Cyberbills, the
        provisions of SFAS 142 will be applicable beginning January 1, 2002.
        The provisions of both SFAS 141 and SFAS 142 will apply to the
        Corporation's merger with National City Bancorporation which was
        completed on August 1, 2001, the Brokat acquisition completed on
        September 21, 2001 and the acquisition of the Arizona branches.  For the
        three months ended September 30, 2001 and 2000, the estimated after-tax
        goodwill amortization which would cease under the provisions of SFAS 142
        was approximately $4.0 million and $4.1 million, respectively, and for
        the nine months ended September 30, 2001 and 2000, was approximately
        $11.3 million and $11.1 million, respectively.  The Corporation is
        assessing whether SFAS 142 will result in a reduction of amortization
        of identifiable intangibles and has not yet determined how the
        impairment provisions of the standard will affect its financial
        statements.

  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 September 30, 2001, interest rate swaps designated as trading
        consisted of $311.5 million in notional amount of receive fixed/pay
        floating with an aggregate positive fair value of $2.6 million and
        $297.2 million in notional amount of pay fixed/receive floating with an
        aggregate negative fair value of $3.4 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.   Acquisitions

        The Corporation completed the following acquisitions during the third
        quarter of 2001:

                On September 21, 2001, the Corporation, through its Metavante
                subsidiary, completed the purchase of substantially all the
                assets of the Atlanta-based North American Internet Banking
                division of Brokat Technologies.  The Brokat Financial
                Applications provide technology for consumer, business and
                corporate e-banking.  Initial goodwill, subject to the
                completion of appraisals and valuations of the assets acquired
                and liabilities assumed, amounted to $19.7 million.

                On August 1, 2001 the Corporation completed it merger with
                National City Bancorporation, a Minneapolis, Minnesota-based
                bank holding company.  National City Bancorporation had assets
                of $1.1 billion and liabilities of $0.8 billion.  There were
                4,544,209 new shares issued in the acquisition.  Initial
                goodwill, subject to the completion of appraisals and valuations
                of the assets acquired and liabilities assumed, amounted to
                $107.9 million.

                During the third quarter the Corporation completed the
                acquisition of twelve branches in Arizona.  Total assets
                acquired amounted to $537.9 million of which loans acquired were
                $344.8 million.  Total deposits acquired were $455.2 million.
                Initial goodwill, subject to the completion of appraisals and
                valuations of the assets acquired and liabilities assumed,
                recorded in this transaction amounted to $50.0 million.

  12.   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.

        Prior period segment information for the Banking segment and Data
        Services segment have been restated for the transfer of certain assets
        and liabilities of the Data Services Division, which represent the
        payment services or item processing line of business.

        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.

        The following tables present revenue and operating income by line of
        business for Banking.  This information is based on the Corporation's
        product profitability measurement system and is an aggregation of the
        revenues and expenses associated with the products and services within
        each line of business.  Net interest income is derived from the
        Corporation's internal funds transfer pricing system, expenses are
        allocated based on available transaction volumes and the provision for
        loan and lease losses is allocated based on credit risk.  Equity is
        assigned to products and services on a basis that considers market,
        operational and reputation risk. ($ in millions):

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

                 THREE MONTHS ENDED SEPTEMBER 30, 2001 and 2000
                 ----------------------------------------------

Net income for the third quarter of 2001 amounted to $83.3 million compared
to $51.6 million for the same period in the prior year.  Basic and diluted
earnings per share were $.78 and $.75 respectively for the three months ended
September 30, 2001, compared with $.49 and $.47 respectively for the three
months ended September 30, 2000.  The return on average assets and average
equity were 1.25% and 12.96% for the quarter ended September 30, 2001 and
0.82% and 9.45% for the quarter ended September 30, 2000.

Net income for the current quarter includes certain losses and expenses
incurred in connection with the announced acquisitions at the Corporation's
Metavante subsidiary.  Net income for the third quarter of 2000 includes
expenses of the withdrawn IPO of Metavante, expenses associated with the
charter consolidation and losses associated with the planned sale of lower
yielding assets and investment portfolio realignment.  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 quarters of 2001 and 2000, excludes the items
discussed above.  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 expenses
associated with charter consolidations and the cumulative effect of the
change in accounting for derivatives and hedging activities while operating
income in the fourth quarter of 2000 excludes certain nonrecurring losses and
expenses associated with balance sheet restructuring, charter consolidations
and the withdrawn Metavante IPO.  "Cash operating income" and related
statistics is 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.  These calculations were 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 third quarter of 2001 amounted to $218.5 million
compared to $164.1 million reported for the third quarter of 2000.  The
reduction in interest rates since early January along with loan growth and
increased spreads on loan products and the impact of the purchase
acquisitions of National City and the Arizona branches contributed to the
$54.4 million increase in net interest income.  Factors negatively affecting
net interest income included a shift in the mix to lower spread bank-issued
deposit products, the ongoing process of lengthening liabilities in order to
reduce future volatility in net interest income due to interest rate
movements, reduced spreads on core deposits due to interest rate declines,
the cost of treasury share repurchases and the cost of acquisitions.

Average earning assets in the third quarter of 2001 increased $1.0 billion
or 4.5% compared to the same period a year ago.  Average loans, including
securitized adjustable rate mortgage loans (ARMs), accounted for $1.3 billion
of the growth in earning assets compared to the third quarter of last year.
Average investment securities, excluding securitized ARMs, declined $0.4
billion while other earning assets increased $0.1 billion.  The Corporation
estimates that approximately $0.8 billion of average earning assets in the
three months ended September 30, 2001, are attributable to the purchase
acquisitions of National City and the Arizona branches.

Average interest bearing liabilities increased $0.5 billion or 2.5% in the
third quarter of 2001 compared to the same period in 2000.  Since the third
quarter of 2000, average interest bearing deposits decreased $0.9 billion
while average total short-term borrowings increased $0.5 billion and average
long-term borrowings increased $0.8 billion. The Corporation estimates that
approximately $0.5 billion of average interest bearing liabilities in the
three months ended September 30, 2001, are attributable to the purchase
acquisitions of National City and the Arizona branches.

Average noninterest bearing deposits increased $0.3 billion or 11.4% compared
to the same period last year. Approximately $0.1 billion of average
noninterest bearing deposits in the three months ended September 30, 2001,
are attributable to the purchase acquisitions of National City and the
Arizona branches.


The growth and composition of the Corporation's quarterly average loan
portfolio for the current quarter and previous four quarters are reflected
in the following table.  Securitized ARM loans which are classified in the
consolidated balance sheets as investment securities available for sale are
included to provide a more meaningful comparison ($ in millions):

Compared with the third  quarter of 2000, total consolidated average loans,
leases and securitized ARMs increased $1.3 billion or 7.3%. Approximately
$0.7 billion of average total consolidated loans, leases and ARMs in the
third quarter of 2001 are attributable to the National City and Arizona
branch acquisitions.  Other factors affecting  the year to year comparison
include: the Corporation sold approximately $46 million of student loans in
the second quarter of 2001, acquired $341 million of home equity loans and
lines related to its private-label banking services in the fourth quarter of
2000 and sold $300.8 million of portfolio ARM loans in the third quarter of
2000.  Also, beginning in the third quarter of 2000, the Corporation began
securitizing indirect auto loans.  Indirect auto loans securitized and sold
in 2000 amounted to $223 million and for the nine months ended September 30,
2001 amounted to $274 million.  The Corporation anticipates that indirect
auto loan origination will continue to be securitized and sold in future
quarters.

Compared with the second quarter of 2001 and excluding the effects of the
banking related acquisitions, total consolidated average loans, leases and
securitized ARMs  decreased  $0.3 billion or 1.6%.  The decrease in total
average commercial loans reflects a slowing in loan demand and the
Corporation's decision to move certain relationships out of M&I and to other
institutions.  Average personal loans were relatively unchanged as portfolio
decreases in auto leases and student loans, tighter spread products, were
offset by growth in consumer and home equity portfolios, both wider spread
products.  The decline in average residential real estate loans reflects


increased prepayment experience as well as the continued strategy of selling
residential real estate loan production in the secondary market.  Residential
real estate loans originated and sold to investors amounted to $1.5 billion
in the first nine months of 2001 compared to $393 million in the first nine
months of the prior year.

Average bank issued deposits increased $1.1 billion or 8.2% in the third
quarter of 2001 compared to the third quarter of 2000.  Average bank issued
deposits associated with the acquisitions in the third quarter of 2001 were
approximately $0.4 billion.  As part of its private-label banking services,
the Corporation acquired $354 million of deposits late in 2000. Excluding the
effect of the current acquisitions, average money market index accounts
accounted for approximately $1.0 billion of the growth in average bank issued
deposits while savings and NOW and money market savings declined $71 million
and bank issued money market savings decreased $161 million. This shift in
mix had an adverse impact on the interest margin.  Noninterest bearing
deposits, excluding acquisitions, increased $189 million . Excluding
acquisitions, average CDs and time deposits declined $0.5 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.

Compared with the third quarter of 2000, average wholesale deposits declined
$1.7 billion or 44.7% and were replaced, in part, with borrowings.  The
decrease in wholesale deposits reflects in part, M&I electing during the
second quarter to discontinue a contractual institutional relationship that
would have repriced to levels above comparable funding alternatives.


Compared with the second quarter of 2001 and excluding the effects of the
banking related acquisitions, total consolidated average deposits decreased
$0.7 billion.  Average bank issued deposits increased $0.1 billion and
consisted of growth in noninterest bearing deposits and interest bearing
activity accounts of $ 0.1 billion and $0.2 billion, respectively, and which
was offset by a decline in average time deposits of $0.2 billion.  Average
wholesale deposits decreased $0.8 billion.

        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 64 basis points since the third
quarter of 2000, which had a negative impact on interest income (FTE) of
approximately $39.5 million.  The increase in the yield of taxable investment
securities reflects the Corporation's realignment of its available for sale
investment securities portfolio through the sale and purchase of
approximately $1.6 billion of U.S. Government Agency securities during the
third quarter of 2000.  The increase in the volume of earning assets,
primarily loans and securitized ARMs, increased interest income by
approximately $19.8 million compared with the third quarter of 2000.  The
cost of interest bearing deposits decreased 170 basis points from the same
quarter of the previous year which reflects rate declines as well as less
reliance on wholesale deposits offset by the shift in the bank issued deposit
mix as previously discussed.  Short-term borrowing costs decreased 185 basis
points and long-term borrowing costs decreased 159 basis points compared with
the third quarter of 2000.  The overall decrease in the cost of interest
bearing liabilities of 163 basis points decreased interest expense by
approximately $82.4 million while the increase in the volume of interest
bearing liabilities increased interest expense by approximately $8.0 million.


In the recent declining interest rate environment, the Corporation has taken
certain actions and will continue to take certain actions, such as issuing
term debt, to lessen the amount of income at risk due to changes in interest
rates.  As a result, net interest income will not experience the same
magnitude of benefit as it might have, absent the actions taken.  In addition
to continuing to seek less costly funding sources, the Corporation may, among
other actions, continue to divest of lower yielding assets through sale or
securitization in the future.

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 September 30, 2001, OREO acquired in satisfaction of debts amounted
to $5.4 million and branch premises held for sale amounted to $0.4 million.
Approximately $2.8 million of OREO acquired in satisfaction of debts relates
to the National City acquisition.

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 September 30, 2001, nonperforming loans and leases amounted to $171.5
million or 0.90% of consolidated loans and leases of $19.0 billion, an
increase of $26.8 million or 18.5% since June 30, 2001. Nonaccrual loans and
leases, primarily commercial loans,  accounted for the increase compared to
the prior quarter.  At September 30, 2001, approximately $26.6 million of
nonperforming loans are related to recent acquisitions.

Net charge-offs amounted to $11.1 million or 0.24% of average loans in the
third quarter of 2001 compared with net charge-offs of $6.6 million or 0.15%
of average loans in the second quarter of 2001 and $7.4 million or 0.17% of
average loans in the third quarter of the prior year.

In light of the events of September 11th, the Corporation performed
additional assessments of its loans to certain industries which may have
become more vulnerable.  These include loans to airlines, travel and leisure
industries, auto suppliers and other transportation related industries and
insurance.  The Corporation has concluded that there are no large
concentrations of loans or unusual draw down activity with respect to the
loans to these industries.  In addition, nonperforming loans and loans
considered problem or watch type credits (loans considered to have a higher
risk of becoming nonperforming) to these industries appear to be
representative of the rest of portfolio.  Only through the passage of time,
over future quarters, will the Corporation be able to determine the strength
of those borrowers.

The allowance for loan and lease losses represents management's estimate of
probable losses which have occurred as of the date of the financial
statements.  In determining the adequacy of the reserve the Corporation
evaluates the reserves necessary for specific nonperforming loans and also
estimates losses in other loans and leases.  As a result, the allowance for
loans and leases contains the following components:

        Specific Reserve.  The amount of specific reserves 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 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.


        Allocated reserve. The amount of the allocated portion of the
        loss reserve is determined by reserving factors assigned to
        loans and leases based on the Corporation's historical loss
        experience.  Line officers and loan committees are responsible
        for continually assigning grades to commercial loan types based
        on standards established in the Corporation's loan policies and
        adherence to the standards is closely monitored by the
        Corporation's Loan Review Group. Loan grades are similar to, but
        generally more conservative than, regulatory classifications.
        In addition, reserving factors are applied to retail and smaller
        balance ungraded credits as well as specialty loan products such
        as credit card, student loans and mortgages. Reserving factors
        are derived and are determined based on such factors as
        historical charge-off experience, remaining life, and industry
        practice for reserve levels.  The use of industry practice is
        intended to prevent an understatement of reserves based upon an
        over-reliance on historical charge-offs during favorable
        economic conditions.

        Management determines a portion of the allocated loss reserve
        based on factors that cannot be associated with a specific
        credit.  These factors include management's subjective
        evaluation of local, national and international economic and
        business conditions, changes to underwriting standards and
        marketing channels such as use of centralized retail and small
        business credit centers, trends towards higher advance rates and
        longer amortization periods and the impact of acquisitions on
        the Corporation's credit risk profile as well as management's
        attempt to ensure that the overall reserve appropriately
        reflects a margin for the imprecision necessarily inherent in
        estimates of expected credit losses.

Management's evaluation of the factors described above resulted in an
allowance for loan and lease losses of $264.7 million at September 30, 2001
compared to $244.5 million at June 30, 2001.  The level of reserve reflects
management's belief that losses in the loan and lease portfolio were larger
than would otherwise be suggested by the Corporation's favorable charge-off
experience in recent years; the Corporation's experience, as most recently
evidenced in the current quarter as well as the second and third quarters of
2000, of larger losses in commercial and commercial real estate loans in
brief periods at particular points in economic cycles; and the view that the
absolute level of the allowance should not decline appreciably given the
continued slowing of economic prosperity.


                                OTHER INCOME
                                ------------
Total other income in the third quarter of 2001 amounted to $255.7 million
compared to $197.4 million in the same period last year. Included in other
income in the third  quarter of the prior year  was  $50.1 million of
investment securities losses associated with Corporation's realignment of
its investment portfolio as previously discussed. Excluding the securities
losses, total other income  increased $8.2 million or 3.3% compared to the
third quarter of last year.

Total data processing services revenue amounted to  $144.4 million in the
third quarter of 2001 compared to $145.3 million in the third quarter of
2000.  e-Finance solutions revenue in the third quarter of 2000 includes
buyout fees of $13.7 million compared to $0.8 million in the same quarter
this year.  Excluding buyout fees, e-Finance solutions revenue increased $8.6
million or 37.1% which reflects growth in electronic bill presentment and
payment and electronic banking products for businesses and consumers.
Financial technology solutions revenue, the traditional outsourcing business,
increased $6.0 million primarily due to buyout fees.  This largest source of
data processing services revenue is projected to grow at single digit levels
during 2001 due to continued bank consolidation and a weaker economy.
Professional services fees and software revenue declined primarily due to
lower software consulting fees.  Other revenue declined primarily due to
lower professional services revenue.

Item processing revenue amounted to $11.7 million in the third quarter of
2001 compared to $13.1 million in the third quarter of 2000 and $12.0 million
in the second quarter of 2001.  The slight revenue decline compared to the
second quarter represents some lost activity as a result of the events of
September 11th.  By month-end transaction activity had returned to normal run
rate levels.


Trust services revenue amounted to $30.1 million in the third quarter of
2001, an increase of $0.2 million compared to $29.9 million in the third
quarter of 2000.  Strong sales have offset declines in managed asset values.
Trust services revenue is largely derived from asset-based fees. With
declining equity markets and the continued movement of funds from higher fee
equity funds to lower fee fixed income or money market funds,  maintaining
year-over-year revenue growth in the current market environment will be a
continuing challenge.

Service charges on deposits increased $2.5 million or 13.4% and amounted
$21.2 million in the third quarter of 2001.  National City accounted for
approximately $0.6 million of the revenue in the third quarter of 2001. The
remainder of the increase was primarily attributable to service charges on
commercial demand accounts.

Mortgage banking revenue increased $5.3 million in the third quarter of 2001
compared to the third quarter of 2000.  Gains on the sale of mortgage loans
accounted for the majority of the increase which reflects the increased
origination and sale activity as previously discussed.

Other income in the third quarter of 2001 amounted to $30.0 million compared
to $28.5 million in the third quarter of 2000, an increase of $1.5 million
or 5.0%.  The increase in gains and income from indirect auto
securitizations, which began in the third quarter of 2000 as previously
discussed, accounted for the majority of the increase.


                               OTHER EXPENSE
                               -------------
Total other expense for the three months ended September 30, 2001,
amounted to $339.8 million compared to $280.8 million for the three ended
September 30, 2000.

Non recurring expenses in the third quarter of 2001 consisted of the
following:

        As previously announced, transition expenses incurred in the
        third quarter in conjunction with the second quarter
        acquisitions of Derivion and Cyberbills amounted to
        approximately $3.5 million of which $1.6 million is
        attributable to salaries and benefits.  The Corporation
        estimates that transition expenses in the fourth quarter with
        respect to these acquisitions will also be approximately $3.5
        million.

        Nonrecurring costs related to the third quarter acquisition of
        Brokat's North American internet banking operations by
        Metavante amounted to approximately $34.5 million.  In
        conjunction with this acquisition four locations and five
        technology platforms will be consolidated resulting in
        severance of $3.8 million and facility closure charges of
        approximately $10.2 million.  Write-offs of existing
        technology and software which will be replaced by Brokat's
        software amounted to $20.5 million.

Non recurring expenses in the third quarter of 2000 consisted of the
following:

        As previously discussed, the Corporation sold $300.8 million
        of portfolio ARM loans as part of its balance sheet management
        strategy and realized losses of $3.1 million.

        Organizational costs associated with Metavante's withdrawn IPO
        amounted to $2.0 million.

        Single charter related expenses incurred amounted to $4.2 million.

Excluding these nonrecurring charges, total other operating expense
amounted to $301.8 million in the third quarter of 2001 compared to $271.5
million in the third quarter of 2000, an increase of $30.3 million or
11.1%.

Approximately $8.8 million of operating expenses in the third quarter of
2001 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 and the
effect of acquisitions, Metavante operating expense growth represents over
half of all of the consolidated operating expense growth and reflects the
cost of  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 September 30, 2001 and 2000 and December 31, 2000 are:

  Excluding Intangible Amortization            50.4 %        53.4 %        54.1 %


Salaries and employee benefits expense amounted to $179.5 million in the
third quarter of 2001 including the severance and transitional charges of
$5.4 million previously discussed.  Excluding the charge, salaries and
benefits expense amounted to $174.1 million compared to $162.2 million in the
third quarter of 2000, an increase of $11.9 million or 7.3%.  Operating
salaries and employee benefits expense associated with acquisitions accounted
for $5.7 million of the increase.  Continued adverse claims experience in
employee health plans added $3.1 million to expense in the current quarter
compared to the same period in the prior year.

Nonrecurring charges included in occupancy and equipment expense in the
third quarter of 2001 amounted to approximately $6.8 million.  Excluding
these items, occupancy and equipment expense in the third quarter of 2001
amounted to $45.2 million and increase of  $3.1 million since the third
quarter of 2000.  Occupancy and equipment expense associated with the
current period acquisitions accounted for approximately $1.6 million of
the increase.

Excluding the effect of acquisitions, Metavante's operating expense growth
accounted for approximately $1.5 million or 68% of the increase in software,
supplies and printing and processing expenses and accounted for all of the
decline in professional fees in the third quarter of 2001 compared to the
third quarter of 2000.  Expenses contributed by the acquisitions for these
items were approximately $0.9 million.

Approximately $1.3 million of intangible amortization in the third quarter
of 2001 represents write-downs of existing intangibles impaired as a
result of the Brokat acquisition.

Other expense amounted to $55.4 million in the third quarter of 2001.
Included in this category in the current quarter were nonrecurring charges
aggregating $23.9 million associated with Metavante's acquisitions.
Excluding these charges, other expense amounted to $31.5 million in the
current quarter compared to $18.2 million in the third quarter of last
year, an increase of $13.3 million. Customer related expense, including
advertising and promotion, was $2.5 million higher in the current quarter
compared to the same period last year.  Recourse liability obligation
reversals amounted to $1.4 million in the third quarter of 2000.


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 $10.8 million in the third quarter of 2000 and in the
current quarter amounted to $2.8 million resulting in an increase of $8.0
million in other expense in the third quarter of 2001 compared to third
quarter of 2000.


                            INCOME TAXES
                            ------------
The provision for income taxes for the three months ended September 30,
2001 amounted to $38.8 million or 31.8% of pre-tax income compared to
$23.0 million or 30.9% of pre-tax income for the three months ended
September 30, 2000.


              NINE MONTHS ENDED SEPTEMBER 30, 2001 AND 2000
              ---------------------------------------------
Net income for the nine months ended September 30, 2001 amounted to $229.2
million compared to $230.8 million in the same period of 2000.  Basic and
diluted earnings per share were $2.17 and $2.11, respectively for the nine
months ended September 30, 2001 compared to $2.19 and $2.12, respectively
for the same period last year.  The year to date return on average equity
was 12.81% in the current period and 14.57% for the nine months ended
September 30, 2000.

Net income for the first nine months of 2001, includes certain losses and
expenses incurred in connection with the previously announced structural
changes and acquisitions at the Corporation's Metavante subsidiary, auto
lease residual value write-downs, the final charge for the charter
consolidation and the cumulative effect of the change in accounting for
derivatives and hedging activities.  Net income for the first nine months of
the prior year includes the cumulative effect of the change in accounting for
certain conversion services provided by Metavante as well as security losses
and losses from the sale of ARM loans, single charter expenses and expenses
associated with the withdrawn IPO of Metavante.  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 nine months ended September 30, 2001 and
2000, respectively.  Operating income for the nine months ended September 30,
2001, and 2000, excludes the nonrecurring items previously discussed. "Cash
operating income" and related statistics is 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.  These
calculations were specifically formulated by the Corporation and may not be
comparable to similarly titled measures reported by other companies.

The increase in operating income was primarily  due to growth in net interest
income of $107.3 million or 21.5%.  Other income increased 3.2% and was
driven by data processing services and mortgage banking revenue.  The
provision for loan and lease losses increased $12.6 million and other
operating expenses increased $76.8 million.

described form 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 2000 Annual Report on Form 10-K.  Updated information
regarding the Corporation's use of derivative financial instruments is
contained in  Note 11, 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 confine 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 across the array of 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 information
about 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 are 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 result into the Corporation's
budgeted / forecasted pre-tax  income for the ensuing twelve months.
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
                            -----------------------------------------------------
                            September 30,   June 30,     March 31,   December 31,
                                 2001         2001         2001          2000
                            ------------- ------------ ------------- ------------
                                                         
Hypothetical Change in Interest Rate
------------------------------------
  100 basis point gradual:

    Rise in rates                  (2.6)%       (4.6)%       (4.9) %       (6.4) %

    Decline in rates                2.4 %        2.7 %        3.7  %        5.3  %



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 September 30, 2001 the fair value of equity at risk
for a gradual 100bp shift in rates was approximately 1.0% of the market
value of the Corporation.

The Corporation uses derivative financial instruments to manage interest
rate exposure.  A small amount of derivatives are sold to customers where
the Corporation acts as an intermediary.  The Corporation through its
trading accounts matches off these instruments in order to minimize
exposure to market risks.

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.

M&I Trust Services administer $55.6 billion in assets and directly manage
a portfolio of  $12.2 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.
