                           Notes to Financial Statements
                          June 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 six months ended June 30, 2001 and 2000.  The
        results of operations for the three and six months ended June 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 six months ended June 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:


                                                                                                 Other

   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 recent 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.  For the three months ended June 30, 2001
        and 2000, the estimated after-tax goodwill amortization which would
        cease under the provisions of SFAS 142 was approximately $4.7 million
        and $4.4 million, respectively, and for the six months ended June 30,
        2001 and 2000, was approximately $9.2 million and $8.6 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 June 30, 2001, interest rate swaps designated as trading consisted
        of $309.9 million in notional amount of receive fixed/pay floating with
        an aggregate positive fair value of $1.3 million and $309.9 million in
        notional amount of pay fixed/receive floating with an aggregate
        negative fair value of $1.1 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.

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

  11.   Acquisitions

                The Corporation, through its Metavante Subsidiary, completed the
                following acquisitions during the second quarter of 2001:

                Derivion Corporation, a privately held company based in Atlanta
                with operations in Toronto, Canada and London, is a provider of
                e-bill presentment and payment technology.

                CyberBills, Inc. is also a privately held company.  Based in San
                Jose, California with operations in Henderson, Nevada,
                CyberBills is an electronic bill presentment and payment
                application service provider.

                In conjunction with these acquisitions, Metavante incurred
                approximately $7.2 million of charges to write-off other
                technologies replaced by these acquisitions.  The Corporation
                estimates that an addition $7 million of nonrecurring charges
                will be incurred in the third and fourth quarters of 2001.

        On August 1, 2001, the Corporation completed its merger with National
        City Bancorporation which  will be included in the Corporation's
        financial statements beginning in the third quarter of 2001.

  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 transfer to
        the Banking segment occurred at the beginning of the third quarter of
        2000.

        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.

        telephone centers, ATMs and the internet. Intrasegment revenues,

        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 June 30, 2001 and 2000
                 -----------------------------------------
Net income for the second quarter of 2001 amounted to $59.7 million compared
to $90.7 million for the same period in the prior year.  Basic and diluted
earnings per share were $.57 and $.55 respectively for the three months ended
June 30, 2001, compared with $.86 and $.83 respectively for the three months
ended June 30, 2000.  The return on average assets and average equity were
0.92% and 10.22% for the quarter ended June 30, 2001 and 1.46% and 17.39% for
the quarter ended June 30, 2000.

Net income for the current quarter 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 and the final charge for the charter consolidation
initiative announced a year ago.  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 second quarter of 2001 excludes the items discussed
above. 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 third and fourth quarters 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 second quarter of 2001 amounted to $201.2 million
compared to $165.1 million reported for the second quarter of 2000. The
reduction in interest rates of 275 basis points since early January along
with continued loan growth and increased spreads in loan products contributed
to the $36.1 million increase in net interest income. Factors negatively
affecting net interest income included the continued reliance on higher-cost
wholesale funding sources, reduced spreads due to an adverse shift in the mix
of bank-issued deposit types and the ongoing process of lengthening
liabilities in order to reduce future volatility in net interest income due
to interest rate movements.

Average earning assets in the second quarter of 2001 increased $0.8 billion
or 3.7% compared to the same period a year ago.  Average loans, including
securitized adjustable rate mortgage loans (ARMs), accounted for $1.0 billion
of the growth in earning assets compared to the second quarter of last year.
Average investment securities, excluding securitized ARMs, declined $0.3
billion while other earning assets increased $0.1 billion for the three
months ended June 30, 2001 compared with the same period in the prior year.

Average interest bearing liabilities increased $0.4 billion or 2.1% in the
second quarter of 2001 compared to the same period in 2000.  Since the second
quarter of 2000, average interest bearing deposits decreased $0.1 billion
while average total short-term borrowings increased $0.1 billion and average
long-term borrowings increased $0.4 billion.

Average noninterest bearing deposits increased $0.1 billion or 4.2% compared
to the same period last year.


The growth and composition of the Corporation's quarterly average loan
portfolio for the current quarter and previous four quarters are reflected

Compared with the second quarter of 2000, total consolidated average loans,
leases and securitized ARMs increased $1.0 billion or 5.9%. The increase was
almost entirely attributable to commercial banking.  Total loan growth in
commercial banking amounted to $953 million or 9.6% and was driven by
commercial loan growth of $315 million and commercial real estate loan growth
of $597 million of which, $131 million was attributable to commercial


construction loan growth.  Retail banking loan growth amounted to $87 million
or 1.1%.  Loan growth in retail banking was generally adversely affected by
increased prepayment activity.  Home equity loans and lines increased $411
million.  In the fourth quarter of 2000, the Corporation acquired $341
million of home equity loans and lines related to its private-label banking
services.  Personal lease financing receivables increased $132 million.
Residential mortgages decreased $627 million or 20.8% while securitized ARM
loans increased $331 million. In addition to the ongoing sale of residential
mortgage production in the secondary market, late in the third quarter of
2000, the Corporation sold $300.8 million of portfolio ARM loans and late in
the fourth quarter of 2000, securitized $511 million of ARM loans.  The
decline in average student loans of $121 million reflects the sale of
approximately $150 million of such loans late in the second quarter of 2000.
Also, late in the second quarter of 2001, approximately $46 million of
student loans were sold.  Average other personal loans decreased $80 million
or 8.4%.  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 six months ended June 30, 2001
amounted to $161 million.  The Corporation anticipates that indirect auto
loan origination will continue to be securitized and sold in future quarters.

Generally, the Corporation sells residential real estate loan production in
the secondary market.  Residential real estate loans originated and sold to
investors amounted to $1.0 billion in the first half of 2001 compared to $215
million in the first six months of the prior year.

Average bank issued deposits increased $726 million or 5.4% in the second
quarter of 2001 compared to the second quarter of 2000.  As part of its
private-label banking services, the Corporation acquired $354 million of
deposits late in 2000. Average money market index accounts accounted for
approximately $1.1 billion of the growth in average bank issued deposits
while savings and NOW declined $161 million and bank issued money market
savings decreased $164 million. This shift in mix had an adverse impact on
the interest margin.  Noninterest bearing deposits, as previously discussed,
increased $108 million.  Average bank issued deposits were negatively
impacted by the sale of three bank branches in 2000 all located in Illinois.
Total deposits sold amounted to approximately $111 million.  Approximately
$90 million of the aforementioned deposit sales occurred in the second
quarter of 2000.

The Corporation continues to have some reliance on wholesale deposits for
funding.  Compared with the second quarter of 2000, average wholesale
deposits declined  $720 million or 19.9% and were replaced, in part, with
borrowings.  The increase in Brokered CDs of $501 million was offset by a
decrease in Eurodollar term and overnight funds, which are included in
foreign time, of  $787 million and a decrease in brokered money market funds
of $434 million.   The decrease in wholesale deposits reflects in part, M&I
electing during the current quarter to discontinue a contractual
institutional relationship that would have repriced to levels above
comparable funding alternatives.

bearing liabilities, interest earned and interest paid for the current
quarter and prior year second quarter are presented in the following table.

  (a)   Fully taxable equivalent basis (FTE), assuming a Federal income tax
        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 25 basis points since the
second quarter of 2000, which had a negative impact on interest income (FTE)
of approximately $15.4 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 $14.5 million
compared with the second quarter of 2000.  The cost of interest bearing
deposits decreased 80 basis points from the same quarter of the previous year
which reflects, in part, less reliance on wholesale deposits offset by the
adverse shift in the bank issued deposit mix as previously discussed.  Short-
term borrowing costs decreased 138 basis points and long-term borrowing costs
decreased 66 basis points compared with the second quarter of 2000 which
reflects, in part, the greater use of bank notes which were issued in the
later part of 2000.  The overall decrease in the cost of interest bearing
liabilities of 87 basis points decreased interest expense by approximately
$45.5 million while the increase in the volume of interest bearing
liabilities increased interest expense by approximately $8.2 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 June 30, 2001, OREO acquired in satisfaction of debts amounted to
$3.1 million and branch premises held for sale amounted to $0.6 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 June 30, 2001, nonperforming loans and leases amounted to $144.8 million
or 0.81% of consolidated loans and leases of $17.8 billion, an increase of
$6.5 million or 4.7% since March 31, 2001.  Nonaccrual loans and leases
accounted for $6.7 million of the increase compared to the prior quarter.
Nonaccrual residential real estate loans increased $4.1 million. Nonaccrual
commercial, financial and agricultural loans increased $4.3 million.  The
increase in nonaccrual commercial loans reflects the addition of two larger
syndicated loans, which were downgraded by their lead bank near the end of
the quarter. Offsetting this increase was the payoff of one larger syndicated
loan as well as other paydowns, payoffs and charge-offs.  Nonaccrual
commercial real estate, lease financing receivables and personal loans all
decreased compared to the prior quarter.

Net charge-offs amounted to $6.6 million or 0.15% of average loans in the
second quarter of 2001 compared with net charge-offs of $5.8 million or 0.13%
of average loans in the first quarter of 2001 and have remained fairly stable
over the past four quarters.

The allowance for loan and lease losses represents management's estimate of
probable inherent 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 inherent 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 inherent reserve. The amount of the allocated portion
        of the inherent loss reserve is determined by reserving factors
        assigned to loans and leases based on the Corporation's internal
        loan grading system.  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.

        Unallocated inherent reserve.  Management determines the
        unallocated portion of the inherent loss reserve based on
        factors that cannot be associated with a specific credit or loan
        categories.  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.  The unallocated portion
        of the inherent loss reserve also reflects management's attempt
        to ensure that the overall reserve appropriately reflects a
        margin for the imprecision necessarily inherent in estimates of
        expected credit losses.

Management's evaluation of the factors described above resulted in a
allowance for loan and lease losses of $244.5 million at June 30, 2001
compared to $240.3 million at March 31, 2001.  The level of reserve
reflects management's belief that losses inherent 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 continuing loan
growth and the slowing of economic prosperity.


                              OTHER INCOME
                              ------------
Total other income in the second quarter of 2001 amounted to $237.9
million, a decrease of $7.5 million or 3.1%, compared to $245.4 million in
the same period last year.  Included in other income in the current
quarter was approximately $16.0 million of investment securities losses
associated with equity investments held by Metavante relating to the
mortgage origination business as well as an equity investment whose
technology was replaced by Metavante's recent acquisitions of Derivion and
Cyberbills. Excluding the securities losses, total other income amounted
to $253.9 million in the current quarter, an increase of 3.5% compared to
the second quarter of last year.

Total data processing services revenue increased $10.4 million or 8.1%
from $127.7 million in the second quarter of 2000 to $138.1 million in the
current quarter.  Account processing fees increased $13.6 million or 14.3%
and reflects growth in transaction volumes in electronic bill payment and
presentment and electronic banking.  Professional services fees and
software revenue declined primarily due to lower software consulting fees.
Other revenue declined primarily due to lower equipment sales which was
offset by buyout fees, which increased $0.8 million compared to second
quarter of last year.

Trust services revenue amounted to $30.6 million in the second quarter of
2001, an increase of $0.6 million or 2.0% compared to $30.0 million in the
second quarter of 2000.  Trust services revenue is largely derived from
asset-based fees.  Maintaining year-over-year revenue growth in the
current market environment will be a continuing challenge.

Service charges on deposits increased $1.9 million or 10.2% and amounted
$20.4 million in the second quarter of 2001.  The increase was primarily
attributable to service charges on commercial demand accounts.

Mortgage banking revenue increased $8.4 million in the second quarter of
2001 compared to the second 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.

The increase in capital markets revenue is due to gains from the sale of
investments and other net unrealized gains which vary from period to
period.


Life insurance revenue for the second quarter of 2000 includes death
benefit gains of $0.6 million.

Other income in the second quarter of 2001 amounted to $30.7 million
compared to $41.3 million in the second quarter of 2000, a decrease of
$10.6 million or 25.7%.  Gains and income from indirect auto
securitizations, which began in the third quarter of 2000 as previously
discussed, amounted to $2.8 million in the current quarter.  Offsetting
this income was lower gains from the sale of student loans of
approximately $3.4 million.  During the second quarter of 2000, the
Corporation recognized gains from the sale of branches of approximately
$9.9 million.


                          OTHER EXPENSE
                          -------------
Total other expense for the three months ended June 30, 2001, amounted to
$342.6 million including costs attributable to Metavante's acquisitions /
divestitures and its reduction in force and realignment of $14.9 million,
auto lease residual write-downs of $25.0 million and $6.0 million for the
single charter initiative which was completed during the current quarter.
Excluding these nonrecurring items, total other expense amounted to $296.7
million in the current quarter compared to $267.0 million in the second
quarter of last year, an increase of $29.7 million or 11.1%.

As previously announced, Metavante's reduction in force and realignment
consisted of the closing of selected regional offices in Idaho, Maryland,
Michigan, Virginia, and Green Bay, Wisconsin and a general reduction in
force across all classes of employees in the Milwaukee metropolitan area.
Approximately 400 positions were eliminated.  Total costs were
approximately $11.0 million consisting primarily of severance of $9.6
million, lease termination and other occupancy exit costs of $0.7 million
and professional fees, including outplacement services of $0.4 million.
Approximately $5.6 million of the cost was paid as of June 30, 2001.

Also as previously announced, expenses and write-downs incurred in
conjunction with the acquisitions of Derivion and Cyberbills amounted to
$2.8 million and consisted of prepaid maintenance fees and capitalized
software costs associated with other technologies that will be replaced by
the new and enhanced bill presentment and payment technology obtained in
the acquisitions.  In addition, a loss of approximately $1.0 million was
recorded from the sale of the assets of a subsidiary.

Single Charter related expenses incurred in the current quarter consisted
of the costs of programming changes required to support operations and
processes to achieve the scale required in the single charter environment,
systems conversion costs, consulting and other professional fees, costs
incurred to eliminate duplicate loan and deposit customer's accounts and
other affiliate shareholder matters and costs associated with employee
relocation, retention and severance.  During the second quarter of 2001,
the remaining charter mergers were completed and the Corporation believes
there will be no more material single charter expenses in future quarters.
The total cost incurred for this initiative, which began in the third
quarter of 2000, was approximately $21.1 million which is approximately
$3.0 million ($1.0 million after-tax) less than originally estimated.

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 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 June 30, 2001 and 2000 and December 31, 2000 are:

        Excluding Intangible Amortization            52.2 %        53.4 %        52.0 %


Salaries and employee benefits expense amounted to $178.1 million in the
second quarter of 2001 including the severance charges of $9.6 million
previously discussed.  Excluding the charge, salaries and benefits expense
amounted to $168.5 million compared to $158.9 million in the second
quarter of 2000, an increase of $9.6 million or 6.1%.  Operating salaries
and employee benefits expense of Metavante decreased $0.1 million.
Adverse claims experience in employee health plans added $4.3 million to
expense in the current quarter.

Metavante's operating expense growth accounted for approximately $6.1
million or 85% of the increase in net occupancy, equipment, software,
supplies and printing and processing expenses in the second quarter of
2001 compared to the second quarter of 2000.  These expense items also
include approximately $2.6 million of nonrecurring charges relating to
Metavante as previously discussed.

Approximately $2.2 million of the decline in professional fees was
attributable to Metavante.  In addition, there were no fees relating to
mortgage Internet banking software development (Mortgagebot.com) in the
current year.

The increase in shipping and handling is attributable to increased costs
in the banking segment, which includes the item processing business.

The increase in intangibles amortization is primarily attributable to
amortization of loan servicing rights and more particularly amortization
of mortgage servicing rights which accounted for $1.0 million of the
increase in the current quarter compared to the same period in the prior
period and reflect accelerated amortization in response to increased
prepayment activity.

Other expense amounted to $61.1 million in the second quarter of 2001.
Included in this category in the current quarter were nonrecurring charges
aggregating $27.2 million consisting of auto lease residual write-downs of
$25.0 million, Metavante acquisition related software write-downs of $0.9
million, the loss on the sale of assets of a subsidiary of $1.0 million
and other miscellaneous charges related to Metavante's reduction in force
and realignment.  Excluding these charges, other expense amounted to $33.9
million in the current quarter compared to $20.7 million in the second
quarter of last year, an increase of $13.2 million.

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 $11.2 million in the second quarter of 2000 and in the
current quarter amounted to $4.7 million resulting in an increase of $6.5
million in other expense in the second quarter of 2001 compared to second
quarter of 2000.  Customer related expense, including advertising and
promotion, was $3.7 million higher in the current quarter compared to the
same period last year.


                               INCOME TAXES
                               ------------
The provision for income taxes for the three months ended June 30, 2001
amounted to $26.1 million or 30.5% of pre-tax income compared to $43.1
million or 32.2% of pre-tax income for the three months ended June 30,
2000.  The decrease in the effective tax rate is attributable to increased
state income tax benefits associated with the nonrecurring charges
previously discussed.


                   SIX MONTHS ENDED JUNE 30, 2001 AND 2000
                   ---------------------------------------
Net income for the six months ended June 30, 2001 amounted to $145.8
million compared to $179.2 million in the same period of 2000.  Basic and
diluted earnings per share were $1.40 and $1.35, respectively for the six
months ended June 30, 2001 compared to $1.70 and $1.64, respectively for
the same period last year.  The year to date return on average equity was
12.72% in the current period and 17.25% for the six months ended June 30,
2000.

Net income for the first six 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 half of the
prior year includes the cumulative effect of the change in accounting for
certain conversion services provided by 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 six months ended June 30, 2001 and 2000,
respectively.  Operating income for the six months ended June 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 $52.8 million or 15.8%. Other income increased  3.2%  and was
driven by data processing services and mortgage banking revenue.  The
provision for loan and lease losses increased $6.4 million and other
operating expenses increased $46.5 million.

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 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 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

      Hypothetical Change in Interest Rate
      ------------------------------------

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

      Decline in rates                             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 June 30, 2001 the fair value of equity at risk for a gradual 100bp
shift in rates was less than 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 $58.2 billion in assets and directly manage a
portfolio of $12.5 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.
