                           MARSHALL & ILSLEY CORPORATION
                           Notes to Financial Statements
                          March 31, 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 months ended March 31, 2001 and 2000.  The results
     of operations for the three months ended March 31, 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 months ended March
     31, 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 DERATIVE 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

                     Notes to Financial Statements - Continued
                          March 31, 2001 & 2000 (Unaudited)

  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 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 Corporation does not anticipate the adoption of SFAS 140 will
     materially impact its present securitization activities.

  4. A reconciliation of the numerators and denominators of the basic and
     diluted per share computations are as follows (dollars and shares in
     thousands, except per share data):

 10. Derivative Financial Instruments and Hedging Activities

     Interest rate risk, the exposure of the Corporation's net interest
     income and net fair value of its assets and liabilities, to adverse
     movements in interest rates, is a significant market risk exposure that
     can have a material effect on the Corporation's financial position,
     results of operations and cash flows. The Corporation has policies to
     ensure that neither earnings nor fair value at risk exceed established
     guidelines and assesses these risks by continually identifying and
     monitoring changes in interest rates that may adversely impact expected
     future earnings and fair values.

     The Corporation has designed strategies to confine these risks within
     the established limits and indentify appropriate risk / reward trade-
     offs in the financial structure of its balance sheet.  These strategies
     include the use of derivative financial instruments to help achieve the
     desired balance sheet repricing structure while meeting the desired
     objectives of its customers.

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

     At March 31, 2001, interest rate swaps designated as trading consisted
     of $268.8 million in notional amount of receive-fixed / pay-floating
     with an aggregate positive fair value of $1.4 million and $268.8
     million in notional amount of pay fixed receive floating with an
     aggregate negative fair value of $1.3 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 Corporation has fixed rate callable CDs, equity indexed CDs and
     fixed rate long-term debt which expose the Corporation to variability
     in fair values due to changes in market interest rates and, in the case
     of the equity indexed CDs, to changes in the S&P 500 index.

     To limit the Corporation's exposure to changes in fair value due to
     changes in interest rates and the equity index, the Corporation has
     entered into receive-fixed / pay-floating interest rate swaps with
     identical call features, thereby creating the effect of floating rate
     deposits and floating rate long-term debt.  The Corporation has
     determined that the hedges on the long-term debt qualify for the
     special short-cut accounting prescribed by SFAS 133, resulting in no
     ineffectiveness.

     The Corporation also has Agency collateralized mortgage backed
     investment securities designated as available for sale.  The embedded
     prepayment options in the underlying mortgages expose the Corporation
     to variability in fair value in a changing interest rate environment.
     To limit its exposure to changes in fair value, the Corporation has
     designated purchased interest rate floors as a hedge against changes in
     fair value attributable to the embedded prepayment option.

     During the first quarter of 2001, the Corporation sold a portion of the
     floors ($100 million in notional amount).  The adjustment to the
     carrying amount of the hedged investment securities of  $3.2 million is
     being accreted into earnings over the remaining life of the security
     using the interest method.

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

     Cash Flow Hedges
     ----------------
     The Corporation has variable rate loans and variable rate short-term
     borrowings which expose the Corporation to variability in interest
     payments due to changes in interest rates.  The Corporation believes it
     is prudent to limit the variability of a portion of its interest
     receipts and payments.  To meet this objective, the Corporation enters
     into various types of derivative financial instruments to manage
     fluctuations in cash flows resulting from interest rate risk.  At March
     31, 2001, these instruments include interest rate swaps and an interest
     rate floor.

     The interest rate swaps change the variable-rate cash flow exposure on
     the loans and short-term borrowings to fixed-rate cash flows through
     the interest rate swaps.

                          March 31, 2001 & 2000 (Unaudited)

     The purchased interest rate floor also protects the Corporation from
     decreases in interest rates that would result in decreased cash
     interest receipts from the variable rate loans.  Under the agreement,
     the Corporation has the right to receive cash if interest rates
     decrease below a specified level.

     Ineffectiveness arising from differences between the critical terms of
     the hedging instrument and hedged item are recorded in interest income
     or expense based on the transaction that gave rise to the
     ineffectiveness.

     Changes in the fair value of the interest rate swaps or floor
     designated as cash flow hedges are reported in accumulated other
     comprehensive income (AOCI).  These amounts subsequently are
     reclassified to interest income or interest expense as a yield
     adjustment in the same period in which the related interest on the
     variable rate loans and short-term borrowings affects earnings.

     The following table summarizes the Corporation's cash flow hedges at
     March 31, 2001.

     For the three months ended March 31, 2000, the effect on net interest
     income resulting from derivative financial instruments was a positive
     $0.2 million.

 11. Segments

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

     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.


                           MARSHALL & ILSLEY CORPORATION

     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.  Operating income for the banking entities and certain
     other entities also excludes certain assets, liabilities, equity,
     revenues and expenses associated with adjustments, charges or credits
     arising from acquisitions accounted for as purchases (hereinafter
     called acquisition costs).  The accounting policies of the
     Corporation's segments are the same as those described in Note 1 to the
     Corporation's Annual Report on Form 10K, Item 8.  Intersegment revenues
     may be based on cost, current market prices or negotiated prices
     between the providers and receivers of services.

     Based on the way the Corporation organizes its segments and the
     requirements of Statement of Financial Accounting Standards No. 131,
     "DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE AND RELATED INFORMATION",
     the Corporation has determined that it has two reportable segments.
     Information with respect to M&I's segments is as follows:

                                 BANKING

     Banking represents the aggregation of fifteen separately chartered
     banks located in Wisconsin, one bank in Arizona, one federally
     chartered thrift headquartered in Nevada and an operational support
     subsidiary which, beginning in the third quarter of 2000, includes item
     processing.  Banking consists of accepting deposits, making loans and
     providing other services such as cash management, foreign exchange and
     correspondent banking to a variety of commercial and retail customers.
     Products and services are provided through a variety of delivery
     channels including traditional branches, supermarket branches,
     telephone centers, ATMs and the internet.  In addition, the
     Corporation's larger affiliate banks provide numerous services such as
     cash management, regional credit, and centralized accounting to M&I's
     community banking affiliates. Intrasegment revenues, expenses and
     assets have been eliminated in the following information and prior
     periods have been restated to include the item processing line of
     business.  ($ in millions):

     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):

                  THREE MONTHS ENDED MARCH 31, 2001 AND 2000
                  ------------------------------------------

Net income for the first quarter of 2001 amounted to $86.2 million compared
to $88.4 million for the same period in the prior year.  Basic and diluted
earnings per share were $.83 and $.80 respectively for the three months
ended March 31, 2001, compared with $.84 and $.81 respectively for the
three months ended March 31, 2000.  The return on average assets and
average equity were 1.34% and 15.31% for the quarter ended March 31, 2001
and 1.45% and 17.11% for the quarter ended March 31, 2000.

Net income for the current quarter includes certain expenses incurred in
connection with the previously announced plan to reduce the number of
banking charters under which it operates and also includes the cumulative
effect of the change in accounting for derivatives and hedging activities.
Net income for the prior year comparative quarter 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:

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 first quarter of 2001 and
2000 excludes the items discussed above and operating income for 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 first quarter of 2001 amounted to $185.8
million compared to $169.1 million reported for the first quarter of 2000.
Strong loan growth and increased spreads in loan products contributed to
the $16.7 million increase in net interest income despite the continued use
of higher-cost funding sources and reduced spreads in deposit products due
to an adverse shift in the mix of bank-issued deposit types.

Average earning assets in the first quarter of 2001 increased $1.4 billion
or 6.1% compared to the same period a year ago.  Average loans, including
securitized adjustable rate mortgage loans (ARMs), accounted for $1.4
billion or all of the growth in earning assets compared to the first
quarter of last year.  Average investment securities, excluding securitized
ARMs, declined $96.8 million while other earning assets increased $72.0
million for the three months ended March 31, 2001 compared with the same
period in the prior year.

Average interest bearing liabilities increased $1.0 billion or 5.1% in the
first quarter of 2001 compared to the same period in 2000.  Since the first
quarter of 2000, average interest bearing deposits increased $0.6 billion.
Over 74% of the growth in interest bearing deposits were attributable to
bank-issued deposits.  Average total short-term borrowings decreased $218
million and reflects a shift away from fed funds and repurchase agreements
and short-term bank notes to longer-term liabilities.  Long-term borrowings
increased $0.6 billion.

Average noninterest bearing deposits increased $49 million or 1.9% 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
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 first quarter of 2000, total consolidated average loans,
leases and securitized ARMs increased $1.4 billion or 8.1%.  Approximately
63% of consolidated average loan growth was attributable to commercial
banking.  Total loan growth in commercial banking amounted to $878 million
or 9.1% and was driven by commercial loan growth of $361 million and
commercial real estate loan growth of $467 million of which, $88 million
was attributable to commercial construction loan growth.  Retail banking
loan growth amounted to $509 million or 6.9%.  Home equity loans and lines
increased $473 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 $205 million.  Residential mortgages decreased $453 million or
15.8% while securitized ARM loans increased $404 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 $128 million reflects the sale of approximately $150 million of
such loans late in the second quarter of 2000.  Average other personal
loans decreased $51 million or 5.7%.  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 three months ended March 31, 2001 amounted to $68 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 $ 322 million in the first quarter of 2001 compared
to $72 million in the first quarter of the prior year.

funding.  Compared with the first quarter of 2000, average wholesale deposit
growth amounted to $152 million or 4.6%.  The increase in Brokered CDs of $750
million and brokered money market accounts of $124 million was offset by a
decrease in Eurodollar term and overnight funds, which are included in foreign
time, of  $721 million.

Average bank issued deposits increased $494 million or 3.6% in the first
quarter of 2001 compared to the first 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 $858 million of the growth in average bank issued deposits while
savings and NOW declined $199 million and bank issued money market savings
decreased $175 million. This shift in mix had an adverse impact on the
interest margin.  Noninterest bearing deposits, as previously discussed,
increased $49 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.  There were no branch
sales in the first quarter of 2001 or during the first quarter of 2000.


The Corporation's consolidated average interest earning assets and interest
bearing liabilities, interest earned and interest paid for the current quarter
and prior year first quarter are presented in the following table.
Securitized ARM loans that are classified in the balance sheet as investment
securities available for sale are included with loans to provide a more

 (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 increased 31 basis points since the first
quarter of 2000 which had a positive impact on interest income (FTE) of
approximately $13.4 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 $23.7 million
compared with the first quarter of 2000.  The cost of interest bearing
deposits increased 24 basis points from the same quarter of the previous year
which reflects, in part, the adverse shift in deposit mix previously
discussed.  Short-term borrowing costs increased 8 basis points which also
reflects the shift in mix of short-term funding sources.  Long-term borrowing
costs increased 6 basis points compared with the first quarter of 2000 which
is a result of the greater use of bank notes which were issued in the later
part of 2000.  The overall increase in the cost of interest bearing
liabilities of 21 basis points increased interest expense by approximately
$5.7 million while the increase in the volume of interest bearing liabilities
increased interest expense by approximately $15.4 million.


In the recent declining interest rate environment, the Corporation has taken
certain actions 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 things, continue to divest of lower yielding assets through sale or
securitization in the future.

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

OREO is comprised of commercial and residential properties acquired in partial
or total satisfaction of problem loans and branch premises held for sale.  At
March 31, 2001, OREO acquired in satisfaction of debts amounted to $3.2
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 March 31, 2001, nonperforming loans and leases amounted to $138.3 million
or 0.78% of consolidated loans and leases of $17.8 billion, an increase of
$8.9 million or 6.9% since December 31, 2000.  Nonaccrual loans and leases
accounted for $9.2 million of the increase compared to the prior quarter.
Nonaccrual residential real estate loans accounted for $4.3 million of the
increase. Nonaccrual commercial real estate loans increased $3.8 million
driven primarily by multifamily loans.  Two commercial lease financing
receivables placed on nonaccrual accounted for the $1.0 million increase in
nonaccrual leases while nonaccrual commercial and industrial loans were
relatively unchanged.  Nonaccrual loans associated with the cranberry industry
amounted to $13.0 million at March 31, 2001, compared to $13.8 million at
December 31, 2000.  While this sector represents 10% of total nonaccrual
loans, the Corporation feels this industry has stabilized and does not
anticipate further losses.

Net charge-offs amounted to $5.8 million or 0.13% of average loans in the
first quarter of 2001 compared with net charge-offs of $6.8 million or 0.16%
of average loans in the fourth quarter of 2000 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 an
allowance for loan and lease losses of $240.3 million at March 31, 2001
compared to $235.1 million at December 31, 2000.  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 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 first quarter of 2001 amounted to $247.0 million,
an increase of $5.6 million or 2.3%, compared to $241.4 million in the same
period last year.

Total data processing services revenue increased $3.0 million or 2.3% from
$130.0 million in the first quarter of 2000 to $133.0 million in the current
quarter.  Account processing fees increased $10.1 million or 10.7% and
reflects growth in electronic bill payment and presentment and online banking.
Professional services fees and software revenue is somewhat seasonal in nature
and are typically lower in the first quarter.  Other revenue declined
primarily due to lower equipment sales while buyout fees were relatively
unchanged.

The increase in internet banking revenue was driven by increased internet
mortgage lending activity.

Trust services revenue amounted to $30.0 million in the first quarter of 2001,
an increase of $2.2 million or 8.0% compared to $27.8 million in the first
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 $2.3 million or 12.5% and amounted $20.8
million in the first quarter of 2001.  The increase was primarily attributable
to service charges on commercial demand accounts.

Mortgage banking revenue increased $4.0 million in the first quarter of 2001
compared to the first quarter of 2000.  While all sources of mortgage banking
revenue increased compared to the prior year, 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 decrease in capital markets revenue is due to gains from the sale of
investments and other net unrealized gains.   Net securities gains from
Capital Markets investments, which can vary from period to period, amounts to
$6.2 million in the current quarter compared to $14.8 million in the first
quarter of last year.

Other income in the first quarter of 2001 amounted to $30.1 million compared
to $27.5 million in the first quarter of 2000, an increase of $2.6 million or
9.5%.  Gains and income from indirect auto securitizations, which began in the
third quarter of 2000 as previously discussed, amounted to $5.6 million in the
current quarter. Offsetting this income was lower investment income on
nonqualified benefit plan assets of approximately $1.5 million.  During the
first quarter of 2000 the Corporation recognized reversion income associated
with the final settlement of an acquired pension plan of approximately $1.8
million.


                                OTHER EXPENSE
                                -------------
Total other expense for the three months ended March 31, 2001, amounted to
$290.8 million including costs attributable to the single charter initiative.

Single Charter related expenses incurred in the current quarter amounted to
$6.0 million.  Such expenses 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
first quarter of 2001, ten charter mergers were completed.

Excluding this item, total other expense amounted to $284.8 million in the
first quarter of 2001 compared to $268.0 million in the first quarter of 2000
an increase of $16.8 million or 6.3%.

The Corporation's nonbanking businesses, especially its Data Services segment
("Metavante"), continue to be the primary contributors to operating expense
growth.  Metavante expense growth represents over half of all of the
consolidated operating expense growth and reflects the cost of adding
processing capacity and other related costs associated with developing new
products and services.  Expense growth in the current quarter for the banking
segment reflects start-up costs associated with its private-label banking
services and losses associated with retail auto lease residual values.

Expense control is sometimes measured in the financial services industry by
the efficiency ratio statistic.  The efficiency ratio is calculated by taking
total other expense (excluding nonrecurring charges) divided by the sum of
total other income (including Capital Markets revenue but excluding investment
securities gains or losses) and net interest income on a fully taxable
equivalent basis.  The Corporation's efficiency ratios for the three months
ended March 31, 2001 and 2000 and the year ended December 31, 2000 are:

    Excluding Intangible Amortization              51.8 %        53.4 %        51.6 %



Salaries and employee benefits expense amounted to $167.9 million in the first
quarter of 2001 compared to $157.3 million in the first quarter of 2000, an
increase of $10.6 million or 6.7%.  Salaries and employee benefits expense of
Metavante  increased $8.0 million.  At March 31, 2001, Metavante had
approximately 294 more full time equivalent employees when compared to March
31, 2000.  Compared to the first quarter of 2000, expense growth in the
current quarter in salaries and employee benefits was $2.4 million or 3.9% for
the banking segment.

Data Services expense growth accounted for approximately $6.2 million or 96%
of the increase in net occupancy, equipment, software, supplies and printing
and processing expenses in the first quarter of 2001 compared to the first
quarter of 2000.

Approximately $1.3 million of the decline in professional fees was
attributable to Metavante and was offset by increased fees in mortgage and
internet banking.


Other expense amounted to $23.9 million in the first quarter of 2001, and
was relatively unchanged compared to the first quarter of 2000.  Lower cost
of sales associated with equipment sales and card plastics revenue was $3.1
million and was offset by losses associated with auto lease residuals.

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 capitalization was $7.2
million in the first quarter of 2000 and in the current quarter amounted to
$6.4 million resulting in an increase of $0.8 million in other expense in
the first quarter of 2001 compared to first quarter of 2000.


                            INCOME TAXES
                            ------------
The provision for income taxes for the three months ended March 31, 2001
amounted to $44.3 million or 33.8% of pre-tax income compared to $46.0
million or 33.7% of pre-tax income for the three months ended March 31,
2000.


                          CAPITAL RESOURCES
                          -----------------
Shareholders' equity was $2.31 billion at March 31, 2001 compared to $2.24
billion at December 31, 2000 and $2.07 billion at March 31, 2000.

The Corporation had net unrealized gains on securities available for sale
at March 31, 2000 of $72.5 million, an increase in market value net of
related income tax effects of $34.4 million since December 31, 2000.  Net
unrealized losses associated with derivative financial instruments
designated cash flow hedges at March 31, 2001 amounted to $12.9 million.

For the three months ended March 31, 2000, M&I repurchased 0.3 million shares
of its Common Stock.  The aggregate cost of the shares repurchased was $15.5
million.

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

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 March 31, 2001 and December 31, 2000:


                                         Impact to Annual Pretax Income as of
                                         ------------------------------------
                                               March 31,     December 31,
                                                 2001            2000
                                         ----------------- ------------------
                                                      
      Hypothetical Change in Interest Rate
      ------------------------------------
      100 basis point gradual:

      Rise in rates                               (4.9)%       (6.4)%

      Decline in rates                             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 March 31, 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 exists, but due to the nature of the investments, cannot
be quantified within acceptable levels of precision.

M&I Trust Services administers $56.1 billion in assets and directly manages
a portfolio of  $11.8 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.
