                          Notes to Financial Statements
                       September 30, 2003 & 2002 (Unaudited)

  1.   The accompanying unaudited consolidated financial statements should be
       read in conjunction with Marshall & Ilsley Corporation's ("M&I" or
       "Corporation") 2002 Annual Report on Form 10-K.  The unaudited
       financial information included in this report reflects all adjustments
       consisting only of normal recurring accruals and adjustments which are
       necessary for a fair statement of the financial position and results
       of operations as of and for the three and nine months ended September
       30, 2003 and 2002.  The results of operations for the three and nine
       months ended September 30, 2003 and 2002 are not necessarily indicative
       of results to be expected for the entire year.  Certain amounts in the
       2002 consolidated financial statements and analyses have been
       reclassified to conform with the 2003 presentation.

  2.   New Accounting Pronouncements

       In April 2003, the Financial Accounting Standards Board (FASB) issued
       Statement of Financial Accounting Standards No. 149 (SFAS 149),
       Amendment of Statement 133 on Derivative Instruments and Hedging
       Activities.  This Statement amends and clarifies financial accounting
       and reporting for derivatives instruments, including certain derivative
       instruments embedded in other contracts (collectively referred to as
       derivatives) and for hedging activities under FASB Statement No. 133
       (SFAS 133), Accounting for Derivative Instruments and Hedging
       Activities.  The amendments to SFAS 133 fall principally into three
       categories: amendments related to SFAS 133 Implementation Issues that
       were previously cleared by the FASB during the Derivatives
       Implementation Group process, amendments clarifying the definition of
       a derivative and amendments relating to the definition of expected cash
       flows in FASB Concepts Statement No. 7, Using Cash Flow Information and
       Present Value in Accounting Measurement.  SFAS No. 149 is effective for
       contracts entered into or modified after June 30, 2003.  The provisions
       of SFAS 149 that related to SFAS 133 Implementation Issues that have
       been effective for fiscal quarters that began prior to June 15, 2003,
       continue to be applied in accordance with their respective effective
       dates.  In addition, those provisions of SFAS 149, which relate to
       forward purchases or sales of when-issued securities or other
       securities that do not yet exist, should be applied to both existing
       contracts and new contracts entered into after June 30, 2003.  The
       adoption of SFAS 149 did not materially impact the Corporation's
       present derivatives and hedging activities.

       In May 2003, the FASB issued FASB No. 150, Accounting for Certain
       Financial Instruments with Characteristics of both Liabilities and
       Equity.  This Statement prescribes how an issuer classifies and
       measures certain financial instruments.  Financial instruments within
       the scope of SFAS 150 are required to be classified as liabilities (or
       assets in some circumstances).  Many of those instruments were
       previously classified as equity.  Examples of financial instruments
       that are within the scope of SFAS 150 include: mandatorily redeemable
       equity shares, forward purchase contracts or written put options on the
       issuer's equity shares that are to be physically settled or net cash
       settled and payables that can be settled with a variable number of the
       issuer's equity shares.  SFAS 150 does not apply to features that are
       embedded in a financial instrument that is not a derivative in its
       entirety.  Financial instruments that are not within the scope of SFAS
       150 include: convertible debt, puttable stock or other outstanding
       shares that are conditionally redeemable.  SFAS 150 is effective for
       financial instruments entered into or modified after May 31, 2003, and
       otherwise is effective for the Corporation July 1, 2003.

       The trust preferred securities issued by the Corporation's finance
       subsidiary, M&I Capital Trust A, qualify as mandatorily redeemable
       equity shares under SFAS 150.  As stated in the Corporation's Annual
       Report on Form 10-K for the year ended December 31, 2002, the
       Corporation's accounting policy is to classify these trust preferred
       securities as borrowings net of their related discounts.  The
       distributions, including the related accretion of discount, are
       classified as interest expense for purposes of the Consolidated
       Financial Statements.  On July 31, 2003, the Corporation redeemed all
       of the Floating Rate Debentures held by its subsidiary, MVBI Capital
       Trust, and MVBI Capital Trust redeemed all of its outstanding Floating
       Rate Trust Preferred Securities at an aggregate liquidation amount of
       $14.95 million.

       The Corporation believes that its current accounting policies with
       respect to the trust preferred securities issued by the Corporation's
       finance subsidiaries  are in compliance with SFAS 150 and that there
       will no impact to the Corporation from adopting SFAS 150 as it relates
       to the remaining fixed rate trust preferred securities that were issued
       by M&I Capital Trust A.

                     Notes to Financial Statements - Continued
                       September 30, 2003 & 2002 (Unaudited)

       In January 2003, the FASB issued Interpretation No. 46 (FIN 46),
       Consolidation of Variable Interest Entities.  This Interpretation
       addresses consolidation by business enterprises of variable interest
       entities.  Under current practice, entities generally have been
       included in consolidated financial statements because they are
       controlled through voting interests.  This Interpretation explains how
       to identify variable interest entities and how an entity assesses its
       interests in a variable interest entity to decide whether to
       consolidate that entity.  FIN 46 requires existing unconsolidated
       variable interest entities to be consolidated by their primary
       beneficiaries if the entities do not effectively disperse risks among
       parties involved.  Variable interest entities that effectively disperse
       risks will not be consolidated unless a single party holds an interest
       or combination of interests that effectively recombines risks that were
       previously dispersed.  Transferors to qualifying special purpose
       entities (QSPEs) and "grandfathered" QSPEs subject to the reporting
       requirements of SFAS 140 are outside the scope of FIN 46 and do not
       consolidate those entities.  FIN 46 also requires certain disclosures
       by the primary beneficiary of a variable interest entity or an entity
       that holds a significant variable interest in a variable interest
       entity.

       FIN 46 is applicable for all entities with variable interests in
       variable interest entities created after January 31, 2003 immediately.
       Public companies with a variable interest in a variable interest entity
       created before February 1, 2003, were to  apply the provisions of FIN
       46 no later than the beginning of the first interim reporting period
       beginning after June 15, 2003.

       On October 9, 2003, FASB Staff Position No. FIN 46-6 (FSP 46-6),
       Effective Date of FASB Interpretation No. 46, Consolidation of Variable
       Interest Entities was issued. FSP 46-6 delayed the application of the
       provisions of FIN 46 for public companies with respect to variable
       interest entities created before February 1, 2003 until the first
       interim or annual period ending after December 15, 2003.

       The Corporation's asset transfers are generally to QSP's or to entities
       in which the Corporation does not hold a significant variable interest.
       As a result, the Corporation does not believe that FIN 46 requires the
       consolidation of the conduit or the securitizations in its financial
       statements.  For additional discussion on the Corporation's asset sales
       and securitization activities see Note 7 and the discussion of critical
       accounting policies contained in Item 2, Management's Discussion and
       Analysis of Financial Position and Results of Operations.

       With respect to other interests in entities that may be subject to FIN
       46, such as low-income housing investments, the Corporation is
       continuing to inventory and evaluate those entities and its interests
       to determine if those entities are variable interest entities and, to
       the extent they qualify as variable interest entities, if the
       Corporation is the primary beneficiary or holds a significant variable
       interest.  The Corporation does not anticipate that the adoption of FIN
       46 with respect to these interests will have a material impact to its
       consolidated financial statements.

                          MARSHALL & ILSLEY CORPORATION
                     Notes to Financial Statements - Continued
                       September 30, 2003 & 2002 (Unaudited)

       Statement of Financial Accounting Standards No. 123 (SFAS 123),
       "Accounting for Stock-Based Compensation," establishes financial
       accounting and reporting standards for stock based employee
       compensation plans.

       SFAS 123 defines a fair value based method of accounting for employee
       stock options or similar equity instruments.  Under the fair value
       based method, compensation cost is measured at the grant date based on
       the fair value of the award using an option-pricing model that takes
       into account the stock price at the grant date, the exercise price, the
       expected life of the option, the volatility of the underlying stock,
       expected dividends and the risk-free interest rate over the expected
       life of the option.  The resulting compensation cost is recognized over
       the service period, which is usually the vesting period.

       Compensation cost can also be measured and accounted for using the
       intrinsic value based method of accounting prescribed in Accounting
       Principles Board Opinion No. 25 (APBO 25), "Accounting for Stock Issued
       to Employees."  Under the intrinsic value based method, compensation
       cost is the excess, if any, of the quoted market price of the stock at
       grant date or other measurement date over the amount paid to acquire
       the stock.

       The largest difference between SFAS 123 and APBO 25 as they relate to
       the Corporation is the amount of compensation cost attributable to the
       Corporation's fixed stock option plans and employee stock purchase plan
       (ESPP).  Under APBO 25 no compensation cost is recognized for fixed
       stock option plans because the exercise price is equal to the quoted
       market price at the date of grant and therefore there is no intrinsic
       value. SFAS 123 compensation cost would equal the calculated fair value
       of the options granted.  Under APBO 25 no compensation cost is
       recognized for the ESPP because the discount (15%) and the plan meets
       the definition of a qualified plan of the Internal Revenue Code and
       meets the requirements of APBO 25.  Under SFAS 123 the safe-harbor
       discount threshold is 5% for a plan to be non-compensatory.  SFAS 123
       compensation cost would equal the initial discount (15% of beginning
       of plan period price per share) plus the value of a one year call
       option on 85% of a share of stock for each share purchased.

       As permitted by SFAS 123, the Corporation continues to measure
       compensation cost for such plans using the accounting method prescribed
       by APBO 25.

       Had compensation cost for the Corporation's ESPP and options granted
       after January 1, 1995 been determined consistent with SFAS 123, the
       Corporation's net income and earnings per share would have been reduced
       to the following estimated pro forma amounts:

  7.   Sale of Receivables

       During the third quarter of 2003, $187.5 million of automobile loans
       were sold in securitization transactions.  Gains of $0.8 million were
       recognized and are reported in Other income in the Consolidated
       Statements of Income.  Other income associated with auto
       securitizations, primarily servicing fees, amounted to $1.2 million in
       the current quarter.

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

       Prepayment speed (CPR)                          19-35 %
       Weighted average life (in months)                18.8
       Weighted average expected credit losses
          (based on original balance)                   0.50 %
       Residual cash flow discount rate                 12.0 %
       Variable returns to transferees    Forward one month LIBOR yield curve

       At September 30, 2003, securitized automobile loans and other

                                                                                Total

       During the second quarter of 2003, the Corporation recognized an
       impairment loss of approximately $4.1 million, which is included in net
       investment securities gains in the Consolidated Statements of Income
       for the nine months ended September 30, 2003.

  8.   Goodwill and Other Intangibles:

       The changes in the carrying amount of goodwill for the nine months
       ended September 30, 2003 are as follows (dollars in thousands):


                                                  Banking     Metavante      Others       Total

     Goodwill balance as of January 1, 2003    $   801,977  $   136,672  $     4,687  $   943,336
     Goodwill acquired during the period                --           --           --           --
     Purchase accounting adjustments                 7,749        1,662           --        9,411
                                                -----------  -----------  -----------  -----------
     Goodwill balance as of September 30, 2003 $   809,726  $   138,334  $     4,687  $   952,747
                                                ===========  ===========  ===========  ===========


       Purchase accounting adjustments for the banking segment in the first
       nine months of 2003 were primarily due to the adjustments required to
       be made to the initial estimates of fair value for the loans acquired
       and the deposits and borrowings assumed in the acquisition of
       Mississippi Valley Bancshares, Inc., partially offset by the reduction
       of goodwill allocated to the sale of two branches during the second
       quarter and one branch sold during the third quarter.

       Purchase accounting adjustments for Metavante in the first nine months
       of 2003 represent the net effect of additional contingent consideration
       paid as a result of revenue targets being achieved, offset by the
       return of consideration placed in escrow associated with acquisitions
       completed in 2001 and adjustments required to be made to the initial
       estimates of fair value associated with the PayTrust, Inc. acquisition
       and the Spectrum EBP, LLC acquisition.

       At September 30, 2003, the Corporation's other intangible assets
       consisted of the following ($000's):


                                                                      September 30, 2003

 10.   Derivative Financial Instruments and Hedging Activities

       Trading Instruments and Other Free Standing Derivatives

       The Corporation enters into various derivative contracts primarily to
       focus on providing derivative products to customers which enables them
       to manage their exposures to interest rate risk.  The Corporation's
       market risk from unfavorable movements in interest rates is generally
       economically hedged by concurrently entering into offsetting derivative
       contracts.  The offsetting derivative contracts generally have nearly
       identical notional values, terms and indices.  The Corporation uses
       interest rate futures to economically hedge the exposure to interest
       rate risk arising from the interest rate swap entered into in
       conjunction with its auto securitization activities.

       Interest rate lock commitments on residential mortgage loans intended
       to be held for sale are considered free-standing derivative
       instruments.  The option to sell the mortgage loans at the time the
       commitments are made are also free-standing derivative instruments.
       The change in fair value of these derivative instruments due to changes
       in interest rates tend to offset each other and act as economic hedges.

       Trading and free-standing derivative contracts are not linked to
       specific assets and liabilities on the balance sheet or to forecasted
       transactions in an accounting hedge relationship and, therefore, do not
       qualify for hedge accounting under SFAS 133.  They are carried at fair
       value with changes in fair value recorded as a component of other
       noninterest income.

       At September 30, 2003, free standing interest rate swaps consisted of
       $1.2 billion in notional amount of receive fixed/pay floating with an
       aggregate positive fair value of $16.5 million and $0.7 billion in
       notional amount of pay fixed/receive floating with an aggregate
       negative fair value of $9.0 million.

       At September 30, 2003, interest rate caps purchased amounted to $5.0
       million in notional with a positive fair value of $0.1 million and
       interest rate caps sold amounted to $5.0 million in notional with a
       negative fair value of $0.1 million.

       At September 30, 2003, the notional value of  free standing interest
       rate futures was $4.0 billion with a negative fair value of $0.8
       million.

       The Corporation regularly originates and holds floating rate commercial
       loans that reprice monthly on the first business day to one-month
       LIBOR.  As a result, the Corporation's interest receipts are exposed
       to variability in cash flows due to changes in one-month LIBOR.

       In order to hedge the interest rate risk associated with the floating
       rate commercial loans indexed to one-month LIBOR, the Corporation has
       entered into receive fixed / pay LIBOR-based floating interest rate
       swaps designated as cash flow hedges against the first LIBOR-based
       interest payments received that, in the aggregate for each period, are
       interest payments on such principal amount of its then existing LIBOR-
       indexed floating-rate commercial loans equal to the notional amount of
       the interest rate swaps outstanding.

       Hedge effectiveness is assessed at inception and each quarter on an on-
       going basis using regression analysis that takes into account reset
       date differences for certain designated interest rate swaps that reset
       quarterly.  Each month the Corporation makes a determination that it
       is probable that the Corporation will continue to receive interest
       payments on at least that amount of principal of its existing LIBOR-
       indexed floating-rate commercial loans that reprice monthly on the
       first business day to one-month LIBOR equal to the notional amount of
       the interest rate swaps outstanding.  Ineffectiveness is measured using
       the hypothetical derivative method and is recorded as a component of
       interest income on loans.

       For the three  and nine months ended September 30, 2003, the impact
       from cash flow hedges to net interest income was a negative $16.7
       million and $52.5 million, respectively.

       During the third quarter of 2003, $610.0 million of FHLB floating rate
       advances were retired.  In conjunction with the retirement of debt,
       $610.0 million in notional value of receive floating/pay fixed interest
       rate swaps designated as cash flow hedges against the retired floating
       rate advances were terminated.  The loss in accumulated other
       comprehensive income aggregating $40.5 million ($26.3 million after
       tax) was charged to other expense during the third quarter.  Additional
       floating FHLB advances were issued in the third quarter at lower rates
       and with slightly longer maturities.  These new advances were hedged
       with new receive floating/pay fixed interest rate swaps.

       During the second quarter of 2003, the Corporation announced that it
       would redeem all of the Floating Rate Debentures held by its
       subsidiary, MVBI Capital Trust, and MVBI Capital Trust would redeem all
       of its currently outstanding Floating Rate Trust Preferred Securities
       at an aggregate liquidation amount of $14.95 million.  In conjunction
       with the redemption during the second quarter, the Corporation
       terminated the associated interest rate swap designated as a cash flow
       hedge.  The loss in accumulated other comprehensive income aggregating
       $1.4 million ($0.9 million after tax), was charged to other expense
       during the second quarter of 2003.

       During the first quarter of 2003, the Corporation terminated the fair
       value hedge on long-term borrowings.  The adjustment to the fair value
       of the hedged instrument of $35.2 million is being accreted as income
       into earnings over the expected remaining term of the borrowings using
       the effective interest method.  Also during the quarter, the cash flow
       hedge on commercial paper was terminated.  The $32.6 million in
       accumulated other comprehensive income at the time of termination is
       being amortized as expense into earnings in the remaining periods
       during which the hedged forecasted transaction affects earnings.

 11.   Guarantees

       In November 2002, the FASB issued Interpretation No. 45, Guarantor's
       Accounting and Disclosure Requirements for Guarantees, Including
       Indirect Guarantees of Indebtedness of  Others ("FIN 45").  This
       Interpretation elaborates on the disclosures to be made by a guarantor
       in its interim and annual financial statements about its obligations
       under certain guarantees that it has issued.  It also clarifies that
       a guarantor is required to recognize at the inception of a guarantee,
       a liability for the fair value of the obligation undertaken in issuing
       the guarantee. Loan commitments and commercial letters of credit are
       excluded from the scope of this Interpretation.

       Standby letters of credit are contingent commitments issued by the
       Corporation to support the obligations of a customer to a third party
       and to support public and private financing, and other financial or
       performance obligations of customers.  Standby letters of credit have
       maturities which generally reflect the maturities of the underlying
       obligations.  The credit risk involved in issuing standby letters of
       credit is the same as that involved in extending loans to customers.
       If deemed necessary, the Corporation holds various forms of collateral
       to support the standby letters of credit.  The gross amount of standby
       letters of credit issued at September 30, 2003 was $1.2 billion.  Of
       the amount outstanding at September 30, 2003, standby letters of credit
       conveyed to others in the form of participations amounted to $64.6
       million.  Since many of the standby letters of credit are expected to
       expire without being drawn upon, the amounts outstanding do not
       necessarily represent future cash requirements.  At September 30, 2003,
       the estimated fair value associated with letters of credit amounted to
       $3.3 million.

       Metavante offers credit card processing to its customers.  Under the
       rules of the credit card associations, Metavante has certain contingent
       liabilities for card transactions acquired from merchants.  This
       contingent liability arises in the event of a billing dispute between
       the merchant and a cardholder that is ultimately resolved in the
       cardholder's favor.  In such case, Metavante charges the transaction
       back ("chargeback") to the merchant and the disputed amount is credited
       or otherwise refunded to the cardholder.  If Metavante is unable to
       collect this amount from the merchant, due to the merchant's insolvency
       or other reasons, Metavante will bear the loss for the amount of the
       refund paid to the cardholder.  In most cases this contingent liability
       situation is unlikely to arise because most products or services are
       delivered when purchased, and credits are issued by the merchant on
       returned items.  However, where the product or service is not provided
       until some time following the purchase, the contingent liability may
       be more likely.  This credit loss exposure is within the scope of the
       recognition and measurement provisions of FIN 45.  The Corporation has
       concluded that the fair value of the contingent liability was
       immaterial due to the following factors: (1) merchants are evaluated
       for credit risk in a manner similar to that employed in making lending
       decisions; (2) if deemed appropriate, the Corporation obtains
       collateral which includes holding funds until the product or service
       is delivered or severs its relationship with a merchant; and (3)
       compensation, if any,  received for providing the guarantee is minimal.

       Metavante assesses the contingent liability and records credit losses
       for known losses and a provision for losses incurred but not reported
       which are based on historical chargeback loss experience.  For the nine
       months ended September 30, 2003, such losses amounted to twelve
       thousand dollars.

       The following represents the Corporation's operating segments as of and
       for the three and nine months ended September 30, 2003 and 2002.  There
       have not been any changes to the way the Corporation organizes its
       segments or reports segment financial information.  Fees - Intercompany
       represent intercompany revenues charged to other segments for providing
       certain services.  Expenses - Intercompany represent fees charged by
       other segments for certain services received.  For each segment,
       Expenses - Intercompany are not the costs of that segment's reported
       intercompany revenues.  Intersegment expenses and assets have been
       eliminated. ($ in millions):

During the third quarter, one of the portfolio companies held by the
Corporation's Capital Markets group was sold at a gain.  The gain of $16.2
million is reported in net investment securities gains (losses) in the
Consolidated Statements of Income.

Several income tax audits covering multiple tax jurisdictions were resolved
during the current quarter which positively affected the banking segment by
approximately $25.0 million and the data processing segment (Metavante) by
$4.9 million.  The impact is reported in the provision for income taxes in
the Consolidated Statements of Income.

In conjunction with previous acquisitions, Metavante had made certain
operating decisions with respect to facility and platform consolidations.
During the current quarter, Metavante elected to retain one of the facilities
and the related platforms that previously had been set for closure.  As a
result of these decisions, $8.5 million of liabilities established for the
facility closure, consisting of severance of $2.4 million and lease costs of
$6.1 million were no longer required.  As a result of a change in product
strategy, $15.7 million of related capitalized software costs were determined
to have no future value and were written off.  The financial statement impact
of these decisions are reflected in salaries and employee benefits expense,
net occupancy expense and other expense in the Consolidated Statements of
Income.

 22
As a result of the financial impact of the previously described transactions
and decisions which occurred in the current quarter and in consideration of
the low interest rate environment, the Corporation acquired and terminated
$730.3 million in par value of its longer-term and higher cost debt
obligations.  These debt obligations were replaced with debt obligations that
have a lower cost and slightly longer maturities.  The cost of acquiring and
terminating the existing debt obligations amounted to $54.7 million and is
reported as a component of other expense in the Consolidated Statements of
Income.

The aggregate net income impact of these transactions and decisions was
approximately $0.5 million and was not material to reported net income or
earnings per share for the three and nine months ended September 30, 2003.
The Corporation believes these actions will help to stabilize the net
interest margin and provide increased flexibility to offset the costs of
expansion and other investment opportunities in future periods.


                          NET INTEREST INCOME
                          ___________________

Net interest income for the third quarter of 2003 amounted to $258.7 million
compared to $252.8 million reported for the third quarter of 2002.  For the
nine months ended September 30, 2003, net interest income amounted to $787.1
million compared to $743.1 million for the nine months ended September 30,
2002.  Loan growth, increased spreads on certain loan products and the impact
of the banking acquisitions in 2002 contributed to the increase in net
interest income.  Factors negatively affecting net interest income included
accelerated levels of prepayments, asset repricing in excess of deposit
repricing, the impact from lengthening liabilities in order to reduce future
volatility in net interest income due to interest rate movements and cash
expenditures for repurchases of common stock and acquisitions in the prior
year.  Net interest income for the three and nine months ended September 30,
2003, was not significantly affected by the debt transactions previously
discussed due to the timing of completing those transactions.

Average earning assets in the third quarter of 2003 increased $3.9 billion
or 15.1% and on a year-to-date basis increased $4.2 billion or 16.6% compared
to the same periods a year ago.  Average loans and leases accounted for $3.7
billion of the quarter over quarter growth and $4.0 billion of the year-to-
date period over period growth in earning assets.  Average investment
securities increased $0.5 billion and other short-term investments and
trading securities declined $0.2 billion in the third quarter of 2003
compared to the third quarter of 2002.  On a comparative average year-to-date
basis, average investment securities increased $0.7 billion and other short-
term investments and trading securities declined $0.5 billion in the nine
months ended September 30, 2003, compared to the nine months ended September
30, 2002.  The Corporation estimates that approximately $1.6 billion and $1.8
billion of the average loan and lease growth in the three and nine months
ended September 30, 2003 compared to like periods in the prior year, was
attributable to the 2002 banking acquisitions.

Average interest bearing liabilities increased $2.9 billion or 13.5% in the
third quarter of 2003 compared to the same period in 2002.  For the nine
months ended September 30, 2003, average interest bearing liabilities
increased $3.4 billion or 16.0% over the comparable period.  Average interest
bearing deposits increased $3.0 billion or 20.5% in the third quarter of 2003
compared to the third quarter of last year.  On a year-to-date basis, average
interest bearing deposits increased $3.1 billion or 21.2% in the nine months
ended September 30, 2003, compared to the nine months ended September 30,
2002.  Average borrowings were relatively unchanged in the third quarter of
2003 and increased $0.3 billion or 4.6% in the first nine months of 2003
compared to the same periods in 2002. The Corporation estimates that
approximately $1.5 billion and $1.7 billion of the average interest bearing
deposit growth in the three and nine months ended September 30, 2003 compared
to like periods in the prior year, was attributable to the 2002 banking
acquisitions.

Average noninterest bearing deposits increased $0.8 billion or 24.1% and $0.7
billion or 22.2% in the three and nine months ended September 30, 2003,
respectively, compared to the same periods last year.  Approximately $0.2
billion of the growth in average noninterest bearing deposits in the three
and nine months ended September 30, 2003, compared to the same periods in
2002 was attributable to the 2002 banking acquisitions.

Compared with the third quarter of 2002, total consolidated average loans and
leases increased $3.7 billion or 17.5%.  Approximately $1.6 billion of
average total consolidated loan and lease growth in the third quarter of 2003
was attributable to the 2002 banking acquisitions.  Excluding the impact of
these acquisitions, total average commercial loans and leases increased $1.1
billion or 7.4% primarily due to an increase of $0.8 billion in average
commercial real estate loans.  Total average personal loans and leases
increased $1.0 billion or 11.8% excluding the impact of acquisitions.
Average personal loan and lease growth, excluding acquisitions, was driven
primarily by growth in home equity loans and lines of $0.5 billion with the
remainder of the growth attributable to indirect auto loans and residential
real estate mortgage and construction loans.  From a production standpoint,
residential real estate loan closings declined approximately 8.8% in the
third quarter compared to the second quarter of 2003.  For the nine months
ended September 30, 2003 production was approximately $1.8 billion or 64.8%
greater than production in the first nine months of 2002.  The current
application volume appears to be slowing.  The application volume in
September and early October indicates that fourth quarter loan closings may
be approximately one-half of the volume of closings experienced in the
current quarter.

Compared to the second quarter of 2003, total average loans increased $0.2
billion or 0.8% and was driven by personal loan growth.  Total average
commercial loans and leases were relatively unchanged compared to the second
quarter of 2003.  The growth in average commercial real estate loans in the
current quarter of $164.2 million was offset by a decline in average
commercial loans of $130.8 million.  While total commercial commitments
increased, line utilization declined between the second and third quarters
of the current year.  The Corporation had similar experience in average
commercial loan growth in the third quarter of 2002 compared to second
quarter of 2002 where average commercial loans decreased $88.9 million,
excluding acquisitions, which indicates that some seasonality exists in
commercial lending during the third quarter.

The rate of growth experienced in commercial loans has largely been the
result of attracting new customers in all of the Corporation's markets.
Existing customers are generally not increasing their credit needs but appear
to be successfully managing their businesses through the slower economic
conditions and lower revenue levels.  The Corporation's commercial lending
activities have historically fared well as the economy strengthens and it
anticipates loan demand from existing customers will slowly strengthen
reflecting the condition of its markets in future quarters.  Home equity
loans and lines, which includes M&I's wholesale activity, continue to be the
primary consumer loan product.  The Corporation anticipates these products
will continue to drive growth in the consumer side of its banking activities.

Generally, the Corporation sells residential real estate production in the
secondary market, although selected loans with wider spreads and adjustable
rate characteristics are periodically retained in the portfolio and serve as
a potential source of liquidity in the future.  Residential real estate loans
sold to investors amounted to $1.1 billion in the third quarter of 2003
compared to $0.8 billion in the third quarter of the prior year.  For the
nine months ended September 30, 2003, and 2002, residential real estate loans
sold to investors amounted to $3.2 billion and $1.7 billion, respectively.
At September 30, 2003 and 2002, the Corporation had approximately $42.8
million and $265.7 million of mortgage loans held for sale, respectively.
Gains from the sale of mortgage loans amounted to $19.4 million in the third
quarter of 2003 compared to $10.4 million in the third quarter of last year.
For the nine months ended September 30, 2003, and 2002, gains from the sale
of mortgage loans amounted to $49.7 million and $21.0 million, respectively.

Auto loans securitized and sold in the third quarter of 2003 amounted to $0.2
billion compared to $0.1 billion in the third quarter of last year. For the
nine months ended September 30, 2003, and 2002, auto loans securitized and
sold amounted to $0.5 billion and $0.3 billion, respectively.  Gains from the
sale and securitization of auto loans amounted to $0.8 million in the current
quarter compared to $2.9 million in the same period last year.  For the nine
months ended September 30, 2003, and 2002, gains from the sale and
securitization of auto loans amounted to $6.1 million and $5.9 million,
respectively.

During the third quarter of 2002, the Corporation sold $37.9 million of
student loans.  Gains from the sale of student loans amounted to $1.6 million
in the third quarter of the prior year.  For the nine months ended September
30, 2003 and 2002, the Corporation sold $32.2 million and $43.3 million of
student loans and recognized gains of $1.4 million and $1.8 million,
respectively.

The Corporation anticipates that it will continue to divest narrower interest
rate spread assets through sale or securitization in future periods.

Total average deposits increased $3.9 billion or 21.2% in the third quarter
of 2003 compared to the third quarter of 2002.  The Corporation believes that
annual deposit growth better reflects trends due to the seasonality that
occurs between quarters.  Average deposits associated with the 2002 banking
acquisitions accounted for approximately $1.7 billion of the third quarter
2003 versus 2002 quarterly average deposit growth.  Excluding the effect of
these acquisitions, noninterest bearing deposits increased $0.7 billion while
bank-issued interest bearing activity accounts increased $0.3 billion. The
growth in bank-issued transaction deposits reflects the successful sales
focus on certain activity accounts particularly in the new and expanded
markets.  Excluding acquisitions, average bank-issued time deposits declined
$0.5 billion.  M&I's markets have continued to experience some unprofitable
pricing on single service time deposit relationships to the extent of pricing
time deposits above comparable wholesale levels.  The Corporation has elected
not to pursue such relationships.

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

Compared with the third quarter of 2002, average wholesale deposits increased
$1.7 billion in the current quarter.  The Corporation has made greater use
of wholesale funding alternatives, especially institutional CDs, during the
latter half of 2002 and 2003.  These deposits are funds in the form of
deposits generated through distribution channels other than M&I's own banking
branches.  These deposits allow the Corporation's bank subsidiaries to gather
funds across a wider geographic base and at pricing levels considered
attractive, where the underlying depositor may be retail or institutional.
Access to and use of these funding sources also provide the Corporation with
the flexibility to not pursue unprofitable single service time deposit
relationships as previously discussed.

During the third quarter of 2003, the Corporation's 6.375% subordinated notes
in the amount of $100.0 million matured.  In addition, $51.6 million of the
Corporation's Series E medium-term notes with a fixed coupon rate of 5.75%
were acquired in open-market purchases.  Series E medium term notes
aggregating $50.0 million and MiNotes aggregating $64.5 million were issued
by the Corporation during the third quarter of 2003.  During the third
quarter of 2003, $13.2 million of 4.125% senior bank notes and $22.3 million
of 6.375% subordinated bank notes were acquired in open-market purchases.
Fixed rate advances from the Federal Home Loan Bank ("FHLB") aggregating
$33.2 million with a weighted average coupon of 6.08% were retired during the
current quarter.  In addition, $610.0 million of FHLB floating rate advances
were retired.  Receive floating/ pay fixed interest rate swaps designated as
cash flow hedges on the forecasted interest payments on the retired FHLB
floating rate advances were terminated during the third quarter.  New FHLB
advances in the third quarter of 2003 amounted to $1.1 billion.
Approximately $0.5 billion of the new FHLB advances were fixed rate and $0.6
billion were floating rate advances.  As announced in the second quarter of
2003, MVBI Capital Trust redeemed its Floating Rate Trust Preferred
Securities on July 31, 2003.

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

The net interest margin, as a percent of average earning assets on a fully
taxable equivalent basis ("FTE"), decreased 45 basis points from 3.98
percent in the third quarter of 2002 to 3.53 percent in the third quarter
of 2003.  The yield on average interest earning assets decreased 109 basis
points in the third quarter of 2003 compared to the third quarter of the
prior year.  The cost of bank issued interest bearing deposits in the
current quarter decreased 68 basis points from the same quarter of the
previous year.  The increase in noninterest bearing deposits as previously
discussed provided a benefit to the net interest margin.  The cost of
other funding sources (wholesale deposits and total borrowings) decreased
86 basis points in the current quarter compared to the third quarter of
last year.

On a year-to-date basis, the net interest margin FTE decreased 39 basis
points from 4.04 percent for the nine months ended September 30, 2002 to
3.65 percent for the nine months ended September 30, 2003.  The yield on
average interest earning assets decreased 95 basis points in the first
nine months of 2003 compared to the first nine months of the prior year.
The cost of bank issued interest bearing deposits decreased 63 basis
points while the cost of other funding sources decreased 80 basis points
for the nine months ended September 30, 2003, compared to the nine months
ended September 30, 2002.

Net interest income was affected by a number of factors.  Solid balance
sheet growth and increased loan spreads have been beneficial to net
interest income in the first nine months of 2003.  The current lower
absolute level of interest rates and increased level of prepayments has
shortened the expected life of many of the Corporation's financial assets.
Lower reinvestment rates, holding assets with shorter lives and a
conscious slowing in deposit repricing resulting from selectively lowering
deposit rates, have negatively impacted net interest income.  The
Corporation continued to experience higher levels of prepayments with
respect to its loans and investment securities in the first two months of
the current quarter with some slowing in September.  At this point, the
Corporation estimates that based on the current interest rate environment,
most of the accelerated prepayment activity with respect to its loans and
investment securities has occurred.

 28
Based on the anticipated lower levels of prepayment activity and the
impact of the debt refinancing previously discussed, the Corporation
anticipates the net interest margin as a percent of average earning assets
will stabilize or improve somewhat beginning in the fourth quarter of
2003.  Net interest income and the net interest margin can vary and
continues to be influenced by loan and deposit growth, product spreads,
pricing competition in the Corporation's markets, prepayment activity,
future interest rate changes and various other factors.

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

OREO is principally comprised of commercial and residential properties
acquired in partial or total satisfaction of problem loans and amounted to
$13.6 million at September 30, 2003, compared to $10.5 million at June 30,
2003 and $8.2 million at September 30, 2002.  Approximately $1.7 million
of the increase since June 30, 2003 relates to commercial real estate and
$1.4 million of the increase since June 30, 2003 relates to residential
real estate.

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.

 30
At September 30, 2003, nonperforming loans and leases amounted to $187.3
million or 0.76% of consolidated loans and leases compared to $203.3
million or 0.82% of consolidated loans and leases at June 30, 2003, a
decrease of $16.0 million or 7.9%.  Nonaccrual loans and leases accounted
for $14.9 million of the decrease since June 30, 2003.  Nonaccrual
commercial loans decreased $10.8 million.  Nonaccrual commercial real
estate loans increased $0.7 million.  Nonaccrual construction and land
development loans were relatively unchanged.  Nonaccrual residential real
estate loans decreased $3.6 million.  Nonaccrual consumer loans increased
$0.7 million.  Nonaccrual leases decreased $1.8 million compared to the
second quarter of 2003.

Net charge-offs amounted to $7.9 million or 0.13% of average loans and
leases in the third quarter of 2003 compared to $9.8 million or 0.16% of
average loans in the second quarter of 2003 and $10.7 million or 0.20% of
average loans in the third quarter of 2002.

Credit quality continued to show improvement as evidenced by the decline
in nonperforming loans and leases and net charge-offs which were somewhat
lower than expected based on the state of the economy in the markets the
Corporation serves.  In previous quarters, the Corporation disclosed that
it expects net charge-offs, excluding the airline lease charge-offs taken
in the first quarter, to range from 0.15% to 0.25% for the year and
nonperfoming loans and leases as a percent of total loans and leases
outstanding to be in the range of 80-90 basis points.  Based on this
quarter's experience, it appears that the Corporation's credit quality
ratios will be at the low end of the range in the near term.  Until the
economy demonstrates clear strengthening, some degree of stress and
uncertainty exists and the Corporation believes it is too soon to project
if this quarter's experience will be sustained.

The provision for loan and lease losses amounted to $7.9 million and $53.2
million for the three and nine months ended September 30, 2003,
respectively compared to $18.8 million and $51.0 million for the three and
nine months ended September 30, 2002, respectively.  The Corporation has
not substantively changed any aspect to its overall approach in the
determination of the allowance for loan and lease losses.  There have been
no material changes in assumptions or estimation techniques as compared to
prior periods that impacted the determination of the current period
allowance.  The allowance for loan and lease losses to the total loan and
lease portfolio was 1.41% at September 30, 2003, and 1.40% at September
30, 2002.


                             OTHER INCOME
                             ____________

Total other income in the third quarter of 2003 amounted to $325.0 million
compared to $272.5 million in the same period last year, an increase of
$52.5 million or 19.3%.  For the nine months ended September 30, 2003,
total other income amounted to $910.2 million, an increase of $114.5
million or 14.4% compared to $795.7 million for the nine months ended
September 30, 2002.

Total data processing services revenue amounted to $166.3 million in the
third quarter of 2003 compared to $153.9 million in the third quarter of
2002, an increase of $12.4 million or 8.0%.  On a year to date basis,
total data processing services revenue amounted to $481.4 million for the
first nine months of 2003 compared to $445.2 million in the first nine
months of 2002, an increase of $36.2 million or 8.1%.  e-Finance solutions
revenue increased $4.1 million or 11.0% and $17.0 million or 16.2% in the
three and nine months ended September 30, 2003, respectively, compared to
the same periods in the prior year.  Revenue growth was driven by consumer
payment volume from three large financial institution clients, increased
adoption of electronic bill presentment and payment in the customer base
and revenues associated with the PayTrust acquisition.  Financial
technology solutions revenue, the traditional outsourcing business,
increased $8.3 million or 7.1% in the third quarter of 2003 compared to
the third quarter of last year and increased $19.2 million or 5.6% for the
nine months ended September 30, 2003, compared to the nine months ended
September 30, 2002.  Primary contributors to revenue growth in the current
quarter included electronic funds delivery, card solutions, and private
label banking.  During the current quarter several significant client
conversions to the core financial account processing system were
completed.  Total buyout revenue, which varies from period to period,
decreased $3.5 million in the current quarter compared to the third
quarter of last year  and was $6.0 million less in the first nine months
of 2003 compared to the first nine months of 2002.

For the three months ended September 30, 2003, item processing revenue
amounted to $11.2 million compared to $9.8 million for the three months
ended September 30, 2002, an increase of $1.4 million or 14.3%. For the
nine months ended September 30, 2003, item processing revenue amounted to
$31.0 million compared to $29.2 million for the nine months ended
September 30, 2002, an increase of $1.8 million or 6.3%.  Revenue in the
current quarter includes a payment services contract buyout of $0.6
million.  The  remainder of the increase in revenues is due to new
customers and increased volumes processed.

 31
Trust services revenue increased $3.0 million or 10.6% in the third
quarter of 2003 compared to the third quarter of 2002 amounting to $32.0
million in 2003 and $29.0 million in 2002, respectively.  For the nine
months ended September 30, 2003, trust services revenue amounted to $93.3
million compared to $91.3 million for the nine months ended September 30,
2002, an increase of $2.0 million or 2.1%.  The positive impact from
acquisitions and sales efforts were offset by the decline in market values
of assets under management.  Assets under management were approximately
$14.5 billion at September 30, 2003, compared to $12.9 billion at December
31, 2002, and $12.2 billion at September 30, 2002.  During the third
quarter of 2003, Trust services continued to experience modest shifting of
funds into equities as a result of improved market performance which
provided some benefit to revenue.

Service charges on deposits in the third quarter of 2003 increased $0.5
million or 1.9% compared to the third quarter of 2002.  For the nine
months ended September 30, 2003, service charges on deposits increased
$1.1 million or 1.5% compared with the nine months ended September 30,
2002.  For the three and nine months ended September 30, 2003, service
charges on deposits associated with the Southwest acquisition amounted to
$0.8 million and $2.3 million, respectively.

Total mortgage banking revenue was $24.2 million in the third quarter of
2003 compared with $14.3 million in the third quarter of 2002, an increase
of $9.9 million.  Total mortgage banking revenue was $63.5 million in the
first nine months of 2003 compared with $31.1 million in the first nine
months of 2002, an increase of $32.4 million.  Gains from sales of
mortgages to the secondary market and mortgage-related fees accounted for
the increase.  For the three and nine months ended September 30, 2003, the
Corporation sold $1.1 billion and $3.2 billion of loans to the secondary
market, respectively.  Retained interests in the form of mortgage
servicing rights amounted to $1.7 million in the first nine months of
2003.  For the three and nine months ended September 30, 2002, the
Corporation sold $0.8 billion and $1.7 billion of loans to the secondary
market, respectively.  Retained interests in the form of mortgage
servicing rights amounted to $2.5 million in the first nine months of
2002.

Net investment securities gains in the third quarter of 2003 amounted to
$16.7 million.  As previously discussed, $16.2 million represents the gain
from the sale of one of the portfolio companies held by the Corporation's
Capital Markets group.  For the nine months ended September 30, 2003, net
investment securities gains amounted to $15.7 million.  Gains recognized
by the Corporation's Capital Markets group amounted to $17.9 million,
including the transaction previously discussed.  These gains were offset
by $4.1 million of impairment losses on the  interest-only strips
associated with auto loan securitization activity recognized in the second
quarter of 2003.  The Corporation's Capital Markets Group had losses of
$4.2 million for the three months ended September 30, 2002, and losses of
$4.8 million for the nine months ended September 30, 2002.

Other income in the third quarter of 2003 amounted to $41.7 million
compared to $37.4 million in the third quarter of 2002, an increase of
$4.3 million or 11.6%.  For the nine months ended September 30, 2003,
compared to the nine months ended September 30, 2002, other income
increased $19.2 million or 18.1%.  Approximately $1.5 million and $3.6
million of the increase for the three and nine months ended September 30,
2003, respectively, was attributable to the 2002 banking acquisitions.
Loan fees, which include prepayment charges, and other commissions and
fees, excluding the impact of the Southwest acquisition, increased $6.4
million in the current quarter compared to the third quarter of last year
and for the nine month period increased $15.4 million.  Auto
securitization income decreased $1.6 million and increased $1.5 million
for the three and nine months ended September 30, 2003, respectively,
compared to the same periods of the prior year.  The quarter over quarter
decline was primarily due to lower gains from the sale of auto loans which
was offset by increased servicing fee income.  The increase on a year to
date basis was primarily due to increased servicing fee income.  Auto
loans securitized and sold in the third quarter of 2003 amounted to $0.2
billion compared to $0.1 billion in the third quarter of last year.  Auto
loans securitized and sold in the first nine months of 2003 amounted to
$0.5 billion compared to $0.3 billion in the first nine months of last
year.  Gains from the sale of student loans decreased $1.6 million in the
current quarter compared to the third quarter of 2002.  On a comparative
year to date basis, gains from the sale of student loans declined $0.4
million.  Approximately $32.2 million and $43.3 million student loans were
sold in the first nine months of 2003 and 2002, respectively.  Gains from
the sale of a branch contributed approximately $1.6 million to other
income in the third quarter of 2003.  For the nine months ended September
30, 2003, three branches were sold at an aggregate gain of $2.5 million.
Gains from the sale of other real estate increased $2.1 million in the
nine months ended September 30, 2003 compared to the nine months ended
September 30, 2002.  The increase was primarily due to the sale of one
large property in the first quarter of 2003.  Trading income in the third
quarter of 2003 decreased $2.8 million and on a year to date basis
decreased $5.6 million compared to the same periods last year and was
primarily due to lower income from fair value adjustments on free standing
derivative instruments associated with auto loans sold to the multi-seller
revolving conduit.  Beginning in the second half of 2002 and throughout
2003, the Corporation has employed free standing interest rate futures to
economically hedge the market value volatility from the auto-related
derivative instrument due to changes in interest rates.

                            OTHER EXPENSE
                            _____________

Total other expense for the three months ended September 30, 2003 amounted
to $410.0 million compared to $326.6 million for the three months ended
September 30, 2002, an increase of $83.4 million or 25.6%.  Approximately
$7.0 million of the quarter over quarter expense growth was attributable
to the Southwest acquisition which closed in the fourth quarter of 2002
and was included in M&I's operating expenses since the acquisition date.
Total other expense for the three months ended September 30, 2003 includes
the impact of the reversal of liabilities for a facility closure, write
off of capitalized software costs and the cost of debt refinancing as
previously discussed, which aggregated $61.9 million.  Total other expense
for the three months ended September 30, 2002 includes the transition
costs associated with Metavante's integration of PayTrust which amounted
to $3.9 million.  Excluding the impact of acquisition activity and the
items discussed above, total other expense growth in the third quarter of
2003 compared to the third quarter of 2002 was approximately $18.4 million
or 5.7%.

For the nine months ended September 30, 2003, total other expense amounted
to $1,081.3 million compared to $958.2 million for the nine months ended
September 30, 2002, an increase of $123.1 million or 12.8%. Total other
expense for the nine months ended September 30, 2003 includes the impact
of the reversal of liabilities for a facility closure, write off of
capitalized software costs and the cost of debt refinancing as previously
discussed, which aggregated $61.9 million.  The Corporation estimates that
approximately $28.2 million of the expense growth on a year to date basis
was attributable to the bank and Metavante acquisitions which were
included in M&I's operating expenses since their acquisition dates.  In
addition, the nine months ended September 30, 2003 and 2002, include
expenses for the transition costs associated with Metavante's integration
of PayTrust which amounted to $2.5 million and $3.9 million, respectively.
Excluding the impact of acquisition activity and the items discussed
above, total other expense growth in the first nine months of 2003
compared to the first nine months of 2002 was approximately $34.4 million
or 3.6%.

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 divided by the sum of total other income
(including Capital Markets revenue but excluding investment securities
gains or losses) and net interest income on a fully taxable equivalent
basis.  The Corporation's efficiency ratios for the three months ended
September 30, 2003, and prior four quarters were:

Excluding the impact of the reversal of liabilities for a facility
closure, write off of capitalized software costs, the cost of debt
refinancing and the Capital Markets gain as previously discussed, the
Corporation's consolidated efficiency ratio, excluding Metavante, was
approximately 49.4% for the three months ended September 30, 2003.

Salaries and employee benefits expense amounted to $199.4 million in the
third quarter of 2003 compared to $187.2 million in the third quarter of
2002, an increase of $12.2 million.  For the nine months ended September
30, 2003, salaries and employee benefits expense amounted to $590.1
million compared to $552.0 million for the nine months ended September 30,
2002, an increase of $38.1 million.  Included in salaries and benefit
expense for the three and nine months ended September 30, 2003 was a
reversal of $2.4 million of accrued severance associated with the decision
to keep a facility operational as previously discussed.  Salaries and
employee benefits expense associated with the acquisitions and the
PayTrust transition costs accounted for approximately $1.3 million and
$14.0 million of the increase in salaries and benefits expense for the
three and nine months ended September 30, 2003, respectively.  Variable
incentive compensation, primarily attributable to the banking segment,
increased $6.4 million and $17.5 million in the three and nine months
ended September 30, 2003 compared to the respective comparative periods of
the prior year.

For the three months ended September 30, 2003, occupancy and equipment
expense amounted to $40.3 million compared to $49.4 million in the
comparative three month period in 2002, a decrease of $9.1 million.  On a
year to date basis, occupancy and equipment expense amounted to $133.8
million in the first nine months of 2003 compared to $143.0 million in the
first nine months of 2002, a decrease of $9.2 million.  Included in
occupancy and equipment expense for the three and nine months ended
September 30, 2003 is a reversal of $6.1 million of accrued lease
termination costs associated with the decision to keep a facility
operational as previously discussed.  Occupancy and equipment expense
associated with the PayTrust transition accounted for $1.7 million and
$0.9 million of the decline in this expense in the three and nine months
ended September 30, 2003 compared to the respective periods in the prior
year.  Expense reductions at the banking and Metavante segments more than
offset the added expense from acquisitions.

 33
Software expense in the third quarter of 2003 amounted to $11.7 million
compared to $10.5 million in the third quarter of 2002.  For the nine
months ended September 30, 2003, software expense amounted to $32.4
million compared to $33.1 million for the nine months ended September 30,
2002.  As previously reported, during the first quarter of 2002, the
Corporation's banking segment incurred nonrecurring software charges of
approximately $1.7 million.

For the three months ended September 30, 2003, processing charges amounted
to $13.2 million compared to $11.1 million for the three months ended
September 30, 2002.  For the nine months ended September 30, 2003,
processing charges amounted to $35.9 million compared to $29.6 million for
the nine months ended September 30, 2002.  The quarter over quarter and
year to date over year to date growth in processing charges was primarily
attributable to the banking segment and was due to increased third-party
processing charges associated with wholesale loan activity.

Supplies and printing and shipping and handling expense amounted to $17.8
million in the third quarter of 2003 compared to $17.0 million in the
third quarter of 2002, an increase of $0.8 million or 4.7%.  On a year to
date basis, supplies and printing and shipping and handling expense
amounted to $54.2 million in the first nine months of 2003 compared to
$49.6 million in the first nine months of 2002, an increase of $4.6
million or 9.3%.  Approximately $0.1 million and $0.5 million of the
increase for the three and nine months ended September 30, 2003,
respectively, was attributable to the banking and Metavante acquisitions
and the PayTrust transition costs.  The remainder of the increase was
primarily attributable to Metavante for both comparable periods.

For the three months ended September 30, 2003, professional services
expense amounted to $11.1 million compared to $9.0 million for the three
months ended September 30, 2002, an increase of $2.1 million.
Approximately $0.1 million of the increase in professional services
expense was attributable to the banking and Metavante acquisitions and
transition costs.  For the nine months ended September 30, 2003,
professional services expense amounted to $32.3 million compared to $27.6
million for the nine months ended September 30, 2002, an increase of $4.7
million.  Approximately $0.7 million of the increase in professional
services expense in the first nine months of 2003 compared to the same
period in 2002 was attributable to the banking and Metavante acquisitions
and the PayTrust transition costs.  The  remaining increase was primarily
attributable to increased fees associated with mortgage loan production
and increased fees incurred by Metavante.

Intangible amortization expense decreased $4.4 million in the third
quarter of 2003 compared to the third quarter of 2002 and on a year to
date basis, increased $0.8 million in the first nine months of 2003
compared to the first nine months of 2002.  Core deposit premium
amortization increased $1.3 million and $4.4 million the three and nine
months ended September 30, 2003, compared to the respective periods in the
prior year.  Amortization and valuation reserve adjustments associated
with mortgage servicing rights decreased amortization expense $4.8 million
in the third quarter of  2003 compared to the third quarter of 2002 and on
a year to date basis, decreased amortization expense by $1.7 million.
During the third quarter of 2003, $2.4 million of the valuation reserve
established for mortgage servicing rights was reversed based on the
estimated fair value of the servicing rights at September 30, 2003.  The
carrying value of the Corporation's mortgage servicing rights was $5.6
million at September 30, 2003.

Other expense amounted to $113.1 million in the third quarter of 2003
compared to $34.5 million in the third quarter of 2002, an increase of
$78.6 million.  For the nine months ended September 30, 2003 other expense
amounted to $184.9 million compared to $106.3 million for the nine months
ended September 30, 2002, which was also an increase of $78.6 million.
Included in other expense for the three and nine months ended September
30, 2003, is the cost of the debt retirement and swap terminations, as
previously discussed, which amounted to $54.7 million in the third quarter
of 2003.  For the nine months ended September 30, 2003, such costs
amounted to $56.7 million and include the current quarter transactions
plus the $2.0 million recognized in the second quarter of 2003 associated
with the redemption of MVBI Capital Trust's Floating Rate Trust Preferred
Securities.  Expense associated with the banking and Metavante
acquisitions and the PayTrust transition costs contributed approximately a
net $0.4 million to other expense in the third quarter of 2003 and
contributed a net $2.9 million to other expense in the first nine months
of 2003.  Increases in the cost of business related insurance coverage,
increased spending in advertising and promotion and increased costs
associated with Metavante's card solutions and equipment sales added an
additional $4.2 million to other expense in the third quarter of 2003
compared to the third quarter of 2002 and $10.8 million in the nine months
ended September 30, 2003, compared to the nine months ended September 30,
2002.  Litigation, environmental clean-up and other losses recorded in the
third quarter of 2002 and asset write-downs associated with foreclosed
properties and commercial leasing residual values recorded in the first
quarter of 2002 offset the comparable quarter over quarter and year to
date over year to date expense growth.

 34
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
amortization and write-downs were $16.2 million in the third quarter of
2003 and in the third quarter of 2002 net capitalization amounted to $4.2
million resulting in an increase to other expense over the comparative
quarters of $20.4 million. Net software and conversion amortization and
write-downs were $7.8 million for the nine months ended September 30, 2003
and net capitalization amounted to $11.4 million for the nine months ended
September 30, 2002, resulting in an increase to other expense over the
comparative year to date periods of  $19.2 million.  As previously
discussed, write-downs of capitalized software costs deemed to have no
future value were $15.7 million in the three and nine months ended
September 30, 2003.  Approximately $1.5 million of net software
capitalization in the nine months ended September 30, 2003 related to the
PayTrust acquisition.


                             INCOME TAXES
                             ____________

The provision for income taxes for the three months ended September 30,
2003, amounted to $25.5 million or 15.4% of pre-tax income compared to
$60.7 million or 33.7% of pre-tax income for the three months ended
September 30, 2002. The provision for income taxes for the nine months
ended September 30, 2003, amounted to $159.9 million or 28.4% of pre-tax
income compared to $174.3 million or 32.9% of pre-tax income for the nine
months ended September 30, 2002.

In the normal course of business, the Corporation and its affiliates are
routinely subject to examinations from federal and state tax authorities.
During the third quarter of 2003, several income tax audits covering
multiple tax jurisdictions were resolved which positively affected the
banking segment by approximately $25.0 million and Metavante by $4.9
million and resulted in a lower provision for income taxes in the
Consolidated Statements of Income for the three and nine months ended
September 30, 2003.  Excluding the impact of the income tax audits, the
pro forma effective income tax rate for both the three and nine months
ended September 30, 2003 would have been 33.8%.


                     LIQUIDITY AND CAPITAL RESOURCES
                     _______________________________

Shareholders' equity was $3.34 billion or 9.9% of total consolidated
assets at September 30, 2003, compared to $3.04 billion or 9.2% of total
consolidated assets at December 31, 2002, and $2.72 billion or 9.0% of
total consolidated assets at September 30, 2002.  The increase at
September 30, 2003 was primarily due to earnings net of dividends paid.
The loss in accumulated other comprehensive income was $37.9 million lower
since December 31, 2002, and $23.9 million lower since September 30, 2002.
The net unrealized gain associated with available for sale investment
securities declined $19.2 million since December 31, 2002 while the
unrealized loss associated with the change in fair value of the
Corporation's derivative financial instruments designated as cash flow
hedges declined $57.1 million since December 31, 2002 resulting in the net
increase in Shareholders' equity.  The change in fair value of the
Corporation's derivative financial instruments designated as cash flow
hedges since December 31, 2002 was primarily due to the termination of
certain interest rate swaps associated with the debt retirement in the
third quarter of 2003 and the redemption of the trust preferred securities
in the second quarter of 2003.

The Corporation has a Stock Repurchase Program under which up to 12
million shares can be repurchased annually.  During the third quarter of
2003, 1.6 million common shares were acquired at an aggregate cost of
$50.2 million or $31.33 per common share.  For the nine months ended
September 30, 2003, 1.7 million shares have been acquired at an aggregate
cost of $54.5 million or $31.19 per share.

 35
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.

M&I manages its liquidity to ensure that funds are available to each of
its banks to satisfy the cash flow requirements of depositors and
borrowers and to ensure the Corporation's own cash requirements are met.
M&I maintains liquidity by obtaining funds from several sources.

The Corporation's most readily available source of liquidity is its
investment portfolio.  Investment securities available for sale, which
totaled $4.6 billion at September 30, 2003, represent a highly accessible
source of liquidity.  The Corporation's portfolio of held-to-maturity
investment securities, which totaled $0.9 billion at September 30, 2003,
provides liquidity from maturities and amortization payments.  The
Corporation's mortgage loans held-for-sale provide additional liquidity.
The loans, which aggregated $42.8 million at September 30, 2003, represent
recently funded home mortgage loans that are prepared for delivery to
investors, which generally occurs within thirty to ninety days after the
loan has been funded.

Depositors within M&I's defined markets are another source of liquidity.
Core deposits (demand, savings, money market and consumer time deposits)
averaged $17.7 billion in the third quarter of 2003.  The Corporation's
banking affiliates may also access the federal funds markets or utilize
collateralized borrowings such as treasury demand notes or FHLB advances.

The banking affiliates may use wholesale deposits.  Wholesale deposits are
funds in the form of deposits generated through distribution channels
other than the Corporation's own banking branches.  These deposits allow
the Corporation's banking subsidiaries to gather funds across a national
geographic base and at pricing levels considered attractive, where the
underlying depositor may be retail or institutional.  Access to wholesale
deposits also provides the Corporation with the flexibility to not pursue
single service time deposit relationships in markets that have experienced
some unprofitable pricing levels.  Wholesale deposits averaged $4.4
billion in the third quarter of 2003.

The Corporation utilizes certain financing arrangements to meet its
balance sheet management, funding, liquidity, and market or credit risk
management needs.  The majority of these activities are basic term or
revolving securitization vehicles.  These vehicles are generally funded
through term-amortizing debt structures or with short-term commercial
paper designed to be paid off based on the underlying cash flows of the
assets securitized.  These vehicles provide access to funding sources
substantially separate from the general credit risk of the Corporation and
its subsidiaries.  See Note 7 to the Consolidated Financial Statements for
an update of the Corporation's securitization activities in the third
quarter of 2003.

 36
The Corporation's lead bank, M&I Marshall & Ilsley Bank ("Bank"), has
implemented a bank note program which permits it to issue up to $7.0
billion of short-term and medium-term notes which are offered and sold
only to institutional investors.  This program is intended to enhance
liquidity by enabling the Bank to sell its debt instruments in private
markets in the future without the delays which would otherwise be
incurred.  Bank notes outstanding at September 30, 2003, amounted to $2.2
billion of which $0.6 billion is subordinated and qualifies as
supplementary capital for regulatory capital purposes.  During the third
quarter of 2003, the Bank acquired $13.2 million of its senior notes and
$22.3 million of its subordinated notes in open market purchases as part
of the debt refinancing previously discussed.  No bank notes were issued
during the third quarter of 2003.

The national capital markets represent a further source of liquidity to
M&I.  M&I has filed a shelf registration statement which is intended to
permit M&I to raise funds through sales of corporate debt securities with
a relatively short lead time.  Under the shelf registration statement, the
Corporation may issue up to $0.5 billion of medium-term Series E notes
with maturities ranging from 9 months to 30 years and at fixed or floating
rates.  At September 30, 2003, Series E notes outstanding amounted to $0.2
billion.  During the third quarter of 2003, M&I acquired $51.6 million of
Series E notes in open market purchases as part of the debt refinancing
previously discussed.  Series E notes aggregating $50.0 million were
issued during the third quarter of 2003.  The Corporation may issue up to
$0.5 billion of medium-term MiNotes with maturities ranging from 9 months
to 30 years and at fixed or floating rates.  The MiNotes are issued in
smaller denominations to attract retail investors.  Approximately $64.5
million of MiNotes were issued during the third quarter of 2003.
Additionally, the Corporation has a commercial paper program.  At
September 30, 2003, commercial paper outstanding amounted to $0.3 billion.

Short-term borrowings represent contractual debt obligations with
maturities of one year or less and amounted to $3.1 billion at September
30, 2003.  Long-term borrowings which are scheduled to mature in one year
or less at September 30, 2003 amounted to $1.3 billion.  Other obligations
include future minimum lease payments on facilities and equipment as
described in Note 10 and commitments to extend credit and letters of
credit as described in Note 19 of the Notes to Consolidated Financial
Statements contained in Item 8 of the Corporation's Annual Report on Form
10-K for the year ended December 31, 2002.  Many commitments to extend
credit expire without being drawn upon and letters of credit are
contingent commitments.  The amounts outstanding at any time do not
necessarily represent future cash requirements.  Under Federal Reserve
Board policy, the Corporation is expected to act as a source of financial
strength to each subsidiary bank in circumstances when it might not do so
absent such policy.


                     CRITICAL ACCOUNTING POLICIES
                     ____________________________

The Corporation has established various accounting policies which govern
the application of accounting principles generally accepted in the United
States in the preparation of the Corporation's consolidated financial
statements.  The significant accounting policies of the Corporation are
described in the footnotes to the consolidated financial statements
contained in the Corporation's Annual Report on Form 10-K and updated as
necessary in its Quarterly Reports on Form 10-Q.  Certain accounting
policies involve significant judgments and assumptions by management that
may have a material impact on the carrying value of certain assets and
liabilities.  Management considers such accounting policies to be critical
accounting policies.  The judgments and assumptions used by management are
based on historical experience and other factors, which are believed to be
reasonable under the circumstances.  Because of the nature of judgments
and assumptions made by management, actual results could differ from these
judgments and estimates which could have a material impact on the carrying
values of assets and liabilities and the results of the operations of the
Corporation.  Management continues to consider the following to be those
accounting policies that require significant judgments and assumptions:

                     Allowance for Loan and Lease Losses
                     ___________________________________

The allowance for loan and lease losses represents management's estimate
of probable losses inherent in the Corporation's loan and lease portfolio.
Management evaluates the allowance each quarter to determine that it is
adequate to absorb these inherent losses.  This evaluation is supported by
a methodology that identifies estimated losses based on assessments of
individual problem loans and historical loss patterns of homogeneous loan
pools.  In addition, environmental factors, including regulatory guidance,
unique to each measurement date are also considered.  This reserving
methodology has the following components:

Specific Reserve.  The Corporation's internal risk rating system is used
to identify loans and leases rated "Classified" as defined by regulatory
agencies.  In general, these loans have been internally identified as
credits requiring management's attention due to underlying problems in the
borrower's business or collateral concerns.  Subject to a minimum size, a
quarterly review of these loans is performed to identify the specific
reserve necessary to be allocated to each of these loans.   This analysis
considers expected future cash flows, the value of collateral and also
other factors that may impact the borrower's ability to make payments when
due.  Included in this group are those nonaccrual or renegotiated loans
that 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.  For impaired
loans, impairment is measured using one of three alternatives: (1) the
present value of expected future cash flows discounted at the loan's
effective interest rate; (2) the loan's observable market price, if
available; or (3) the fair value of the collateral for collateral
dependent loans and loans for which foreclosure is deemed to be probable.

 37
Collective Loan Impairment.  This component of the allowance for loan and
lease losses is comprised of two elements.  First, the Corporation makes a
significant number of loans and leases, which due to their underlying
similar characteristics, are assessed for loss as homogeneous pools.
Included in the homogeneous pools are loans and leases from the retail
sector and commercial loans under a certain size, which have been excluded
from the specific reserve allocation previously discussed.  The
Corporation segments the pools by type of loan or lease and using
historical loss information, estimates a loss reserve for each pool.

The second element reflects management's recognition of the uncertainty
and imprecision underlying the process of estimating losses.  Based on
management's judgment, reserves are allocated to industry segments or
product types due to environmental conditions unique to the measurement
period.  Consideration is given to both internal and external
environmental factors such as economic conditions in certain geographic or
industry segments of the portfolio, economic trends in the retail lending
sector, risk profile, and portfolio composition.  Reserves are allocated
based on estimates of loss exposure that management has identified based
on these economic trends or conditions.  The internal risk rating system
is then used to identify those loans within these industry segments that
based on financial, payment or collateral performance, warrant closer
ongoing monitoring by management.  The specific loans mentioned earlier
are excluded from this analysis.

The following factors were taken into consideration in determining the
adequacy of the allowance for loans and lease losses at September 30,
2003:

       Management continues to be concerned over the lack of economic
       improvement forecasted for 2003 and the resulting impact this will
       have on the Corporation's customer base.  Although recent economic
       reports and opinions indicate there may be some signs of
       improvement, the uncertainty remains as to when there may be any
       substantive increase in business activity.  In addition, the retail
       loan portfolio will continue to be affected by the prolonged
       economic conditions as evidenced by the generally increasing
       personal bankruptcy and unemployment rates.

       At September 30, 2003, nonperforming loans and leases amounted to
       $187.3 million or 0.76% of consolidated loans and leases compared to
       $203.3 million or 0.82% of consolidated loans and leases at June 30,
       2003, and $212.1 million or 0.88% of consolidated loans and leases
       at March 31, 2003.  Nonperforming loans and leases decreased $16.0
       million or 7.9% in the third quarter of 2003 compared to the second
       quarter of 2003.  Approximately 79% of the decline was attributable
       to two larger credits.  Average nonperforming loans and leases
       declined $22.1 million in the third quarter of 2003 compared to the
       second quarter of 2003 after remaining at consistent levels between
       the first and second quarters of 2003.  Average nonperforming loans
       and leases amounted to $194.4 million in the current quarter
       compared to $216.5 million in the second quarter of 2003.
       Nonperforming loans and leases were $7.2 million or 3.7% lower at
       September 30, 2003, compared to December 31, 2002.  As stated in
       previous quarters, some of the Corporation's largest nonperforming
       loans are in industries that have undergone well-publicized declines
       during the recent recession.  Among those industries affected are
       construction and related, technology, airline, manufacturing and
       healthcare.

       At the present time, there is no specific industry that is of
       immediate concern, however, the Corporation believes that the
       current economic environment will continue to negatively affect the
       markets and communities it serves in the near term.  While
       nonperforming loans have remained in the 80-90 basis point range
       over the past two years, there continues to be some risk of
       nonperforming loans increasing.

       The Corporation's primary lending areas are Wisconsin, Arizona,
       Minnesota and Missouri.  The recent acquisitions in Minnesota and
       Missouri represent new geographic regions for the Corporation.  Each
       of these regions has cultural and environmental factors that are
       unique to them.  The risk in entering these new regions and the
       uncertainty regarding the inherent losses in their respective loan
       portfolios will remain until the Corporation's credit underwriting
       and monitoring processes are fully implemented.

 38
       Net charge-offs in the third quarter of 2003 amounted to $7.9
       million, or 13 basis points of total average loans and leases
       outstanding this quarter compared to $9.8 million or 16 basis points
       of total average loans and leases outstanding in the second quarter
       of 2003 and $25.8 million or 44 basis points in the first quarter of
       2003.  Included in charge-offs for the first quarter was $19.0
       million related to the carrying value of lease obligations for
       airplanes leased to Midwest Airlines, Inc.  In 2002 and 2001, annual
       net charge-offs have remained in the range of approximately 20 basis
       points.  This range of net charge-offs to average loans is somewhat
       higher than historical levels incurred by the Corporation over the
       past five years.  In previous quarters, the Corporation disclosed
       that it expects net charge-offs, excluding the airline lease charge-
       offs taken in the first quarter, to range from 0.15% to 0.25% for
       the year and nonperfoming loans and leases as a percent of total
       loans and leases outstanding to be in the range of 80-90 basis
       points.  Based on this quarter's experience, it appears that the
       Corporation's credit quality ratios will be at the low end of the
       range in the near term.  Until the economy demonstrates clear
       strengthening, some degree of stress and uncertainty exists and the
       Corporation believes it is too soon to project if this quarter's
       experience will be sustained.

       During the third quarter of 2003, the Corporation's commitments to
       shared national credits were approximately $2.0 billion with usage
       averaging around 41%.  Many of these borrowers are in industries
       currently impacted by the economic climate.  In addition, many of
       the Corporation's largest charge-offs have come from the shared
       national credit portfolio.  Approximately $1.3 million of the net
       charge-offs in the third quarter of 2003 relate to a shared national
       credit.  Although these factors result in an increased risk profile,
       as of September 30, 2003, shared national credit nonperforming loans
       were approximately 0.31% and 0.74% of this segment's total
       commitments and outstandings, respectively.  The Corporation's
       exposure to shared national credits is monitored closely given the
       economic uncertainty as well as this segment's loss experience.

       At September 30, 2003, special reserves continue to be carried for
       exposures to manufacturing, healthcare, production agriculture
       (including dairy and cropping operations), and the airline and
       travel industries.  The majority of the commercial charge-offs
       incurred during the past year were in these industry segments.
       While most loans in these categories are still performing, the
       Corporation continues to believe these sectors have been more
       adversely affected by the economic slowdown.  Reduced revenues
       causing a declining utilization of the industry's capacity levels
       have impacted manufacturing.  As a result, collateral values and the
       amounts realized through the sale or liquidation of manufacturing
       plant and equipment have declined accordingly.

Based on the above loss estimates, senior lending and financial management
determine their best estimate of the required reserve.  Management's
evaluation of the factors described above resulted in an allowance for
loan and lease losses of $348.1 million at September 30, 2003 which was
unchanged since June 30, 2003.  The resulting provisions for loan and
lease losses are the amounts required to establish the allowance for loan
and lease losses to the required level after considering charge-offs and
recoveries.  Management recognizes there are significant estimates in the
process and the ultimate losses could be significantly different from
those currently estimated.

The Corporation has not substantively changed any aspect to its overall
approach in the determination of the allowance for loan and lease losses.
There have been no material changes in assumptions or estimation
techniques as compared to prior periods that impacted the determination of
the current period allowance.

                 Capitalized Software and Conversion Costs
                 _________________________________________

Direct costs associated with the production of computer software that will
be licensed externally or used in a service bureau environment are
capitalized.  Capitalization of such costs is subject to strict accounting
policy criteria, however, the appropriate time to initiate capitalization
requires management judgment.  Once the specific capitalized project is
put into production, the software cost is amortized over its estimated
useful life, generally four years.  Each quarter, the Corporation performs
net realizable value tests to ensure the assets are recoverable.  Such
tests require management judgment as to the future sales and profitability
of a particular product which involves, in some cases, multi-year
projections.  Technology changes and changes in customer requirements can
have a significant impact on the recoverability of these assets and can be
difficult to predict.  Should significant adverse changes occur, estimates
of useful life may have to be revised or write-offs would be required to
recognize impairment.  For the three months ended September 30, 2003, and
2002, the amount of software costs capitalized amounted to $11.8 million
and $14.8 million, respectively.  Amortization expense of software costs,
excluding write-offs, amounted to $11.1 for the three months ended
September 30, 2003 compared to $9.3 million for the three months ended
September 30, 2002.  For the nine months ended September 30, 2003, and
2002, the amount of software costs capitalized amounted to $43.8 million
and $42.5 million, respectively.  Amortization expense of software costs,
excluding write-offs, amounted to $32.6 million and $25.5 million for the
nine months ended September 30, 2003, and 2002, respectively.

In conjunction with previous acquisitions, Metavante had made certain
operating decisions with respect to platform consolidations.  As a result
of a change in product strategy, $15.7 million of related capitalized
software costs were determined to have no future value and were written
off.

 39
Direct costs associated with customer system conversions to the data
processing operations are capitalized and amortized on a straight-line
basis over the terms, generally five to seven years, of the related
servicing contracts.

Capitalization only occurs when management is satisfied that such costs
are recoverable through future operations or penalties (buyout fees) in
the case of early termination.  For the three months ended September 30,
2003, and 2002, the amount of conversion costs capitalized amounted to
$3.2 million, respectively.  Amortization expense amounted to $4.4 million
and $4.5 million for the three months ended September 30, 2003, and 2002,
respectively.  For the nine months ended September 30, 2003, and 2002, the
amount of conversion costs capitalized amounted to $9.4 million and $7.6
million, respectively.  Amortization expense amounted to $12.7 million and
$13.2 million for the nine months ended September 30, 2003, and 2002,
respectively.

Net unamortized costs were ($ in millions):

The Corporation has not substantively changed any aspect to its overall
approach in the determination of the amount of costs that are capitalized
for software development or conversion activities.  There have been no
material changes in assumptions or estimation techniques as compared to
prior periods that impacted the determination of the periodic amortization
of such costs.

               Financial Asset Sales and Securitizations
               _________________________________________

The Corporation utilizes certain financing arrangements to meet its
balance sheet management, funding, liquidity, and market or credit risk
management needs.  The majority of these activities are basic term or
revolving securitization vehicles.  These vehicles are generally funded
through term-amortizing debt structures or with short-term commercial
paper designed to be paid off based on the underlying cash flows of the
assets securitized.  These financing entities are contractually limited to
a narrow range of activities that facilitate the transfer of or access to
various types of assets or financial instruments.  In certain situations,
the Corporation provides liquidity and/or loss protection agreements.  In
determining whether the financing entity should be consolidated, the
Corporation considers whether the entity is a qualifying special-purpose
entity (QSPE) as defined in Statement of Financial Accounting Standards
(SFAS) No. 140, Accounting for Transfers and Servicing of Financial Assets
and Extinguishments of  Liabilities.  For non-consolidation a QSPE must be
demonstrably distinct, have significantly limited permitted activities,
hold assets that are restricted to transferred financial assets and
related assets, and can sell or dispose of non-cash financial assets only
in response to specified conditions.

In January 2003, the FASB issued Interpretation No. 46 ("FIN 46"),
Consolidation of Variable Interest Entities.  This interpretation
addresses consolidation by business enterprises of variable interest
entities.  Under current practice, entities generally have been included
in consolidated financial statements because they are controlled through
voting interests.  This interpretation explains how to identify variable
interest entities and how an entity assesses its interests in a variable
interest entity to decide whether to consolidate that entity.  FIN 46
requires existing unconsolidated variable interest entities to be
consolidated by their primary beneficiaries if the entities do not
effectively disperse risks among parties involved.  Variable interest
entities that effectively disperse risks will not be consolidated unless a
single party holds an interest or combination of interests that
effectively recombines risks that were previously dispersed.  Transferors
to QSPEs and "grandfathered" QSPEs subject to the reporting requirements
of SFAS 140 are outside the scope of FIN 46 and do not consolidate those
entities.  FIN 46 also requires certain disclosures by the primary
beneficiary of a variable interest entity or an entity that holds a
significant variable interest in a variable interest entity.

With respect to its existing securitization activities, the Corporation
does not believe FIN 46 impacts its consolidated financial statements
because its transfers are generally to QSPEs or to entities in which the
Corporation does not hold a significant variable interest.

The Corporation regularly sells automobile loans to an unconsolidated
multi-seller special purpose entity commercial paper conduit in
securitization transactions in which subordinated interests are retained.
The outstanding balances of automobile loans sold in these securitization
transactions were $918.3 million at September 30, 2003.  At September 30,
2003, the carrying amount of retained interests amounted to $47.1 million.

 40
The financial assets are sold in a two-step process that results in a
surrender of control over the assets as evidenced by true-sale opinions
from legal counsel, to unconsolidated entities that securitize the assets.
The Corporation retains interests in the securitized assets in the form of
interest-only strips and a cash reserve account.  Gain or loss on sale of
the assets depends in part on the carrying amount assigned to the assets
sold allocated between the asset sold and retained interests based on
their relative fair values at the date of transfer.  The value of the
retained interests is based on the present value of expected cash flows
estimated using management's best estimates of the key assumptions -
credit losses, prepayment speeds, forward yield curves and discount rates
commensurate with the risks involved.  Actual results can differ from
expected results.

The Corporation reviews the carrying values of the retained interests
monthly to determine if there is a decline in value that is other than
temporary and periodically reviews the propriety of the assumptions used
based on current historical experience as well as the sensitivities of the
carrying value of the retained interests to adverse changes in the key
assumptions.  The Corporation believes that its estimates result in a
reasonable estimate of fair value of the retained interests.

During the second quarter of 2003, the Corporation recognized an
impairment loss of approximately $4.1 million, which is included in net
investment securities gains in the Consolidated Statements of Income for
the nine months ended September 30, 2003.  The difference between revised
assumptions based on actual and projected experience compared to initially
expected assumptions were deemed to be other than temporary.

The Corporation also sells, from time to time, investment securities
classified as available for sale that are highly rated to an
unconsolidated bankruptcy remote QSPE whose activities are limited to
issuing highly rated asset-backed commercial paper with maturities up to
180 days which is used to finance the purchase of the investment
securities.  The Bank provides liquidity back-up in the form of Liquidity
Purchase Agreements.  In addition, the Bank acts as counterparty to
interest rate swaps that enable the QSPE to hedge its interest rate risk.
Such swaps are designated as trading in the Corporation's Consolidated
Balance Sheet.

Under the terms of the Administration Agreement, the Bank, as
administrator of the QSPE, is required to sell interests in the securities
funded by the QSPE to the Bank as the liquidity purchaser under the
liquidity agreements, if at any time (after giving effect to any issuance
of new commercial paper notes and the receipt of payments under any swap
agreement) the QSPE has insufficient funds to repay any maturing
commercial paper note and the Bank, as liquidity agent, has received a
notice of such deficiency.  The Bank, as the liquidity provider, will be
obligated to purchase interests in such securities under the terms of the
liquidity agreement to repay the maturing commercial paper notes unless
(i) after giving effect to such purchase, the aggregate of securities,
purchased under the relevant liquidity agreement would exceed the
aggregate maximum liquidity purchase amount under such liquidity agreement
or (ii) certain bankruptcy events with respect to the QSPE have occurred;
provided that the Bank is not required to purchase any defaulted security.
For this purpose, a defaulted security is any security that is rated below
"Caa2" by Moody's and below "CCC" by Standard & Poors.  To date, the Bank
has never acquired interests in any securities under the terms of the
liquidity agreements.


A subsidiary of the Bank has entered into interest rate swaps with the
QSPE designed to counteract the interest rate risk associated with third
party beneficial interest (commercial paper) and the transferred assets.
The beneficial interests in the form of commercial paper have been issued
by the QSPE to parties other than the Bank and its subsidiary or any other
affiliates.  The notional amounts do not exceed the amount of beneficial
interests.  The swap agreements do not provide the QSPE or its
administrative agent any decision-making authority other than those
specified in the standard ISDA Master Agreement.

At September 30, 2003, highly rated investment securities in the amount of
$208.7 million were outstanding in the QSPE to support the outstanding
commercial paper.

                              Income Taxes
                              ____________

Income taxes are accounted for using the asset and liability method.
Under this method, deferred tax assets and liabilities are recognized for
the future tax consequences attributable to differences between the
financial statement carrying amounts of existing assets and liabilities
and their respective tax basis.  Deferred tax assets and liabilities are
measured using enacted tax rates expected to apply to taxable income in
the years in which those temporary differences are expected to be
recovered or settled.  The effect on tax assets and liabilities of a
change in tax rates is recognized in the income statement in the period
that includes the enactment date.

The determination of current and deferred income taxes is based on complex
analyses of many factors including interpretation of Federal and state
income tax laws, the difference between tax and financial reporting basis
of assets and liabilities (temporary differences), estimates of amounts
currently due or owed such as the timing of reversals of temporary
differences and current accounting standards.  The Corporation's
interpretation of Federal and state income tax laws is periodically
reviewed by the Federal and state taxing authorities who make assessments
based on their determination of tax laws.  Tax liabilities could differ
significantly from the estimates and interpretations used in determining
the current and deferred income tax liabilities based on the completion of
taxing authority examinations.

 41
During the third quarter of 2003, several income tax audits covering
multiple tax jurisdictions were resolved which positively affected the
banking segment by approximately $25.0 million and Metavante by $4.9
million and resulted in a lower provision for income taxes in the
Consolidated Statements of Income for the three and nine months ended
September 30, 2003.


                       FORWARD-LOOKING STATEMENTS
                       __________________________

Items 2 and 3 of this Form 10-Q, "Management's Discussion and Analysis of
Financial Position and Results of Operations" and "Quantitative and
Qualitative Disclosures about Market Risk," respectively, contain forward-
looking statements within the meaning of the safe harbor provisions of the
Private Securities Litigation Reform Act of 1995.  Such forward-looking
statements include, without limitation, statements regarding expected
operating activities and results which are preceded by words such as
"expects", "anticipates" or "believes".  Such statements are subject to
important factors that could cause the Corporation's actual results to
differ materially than those anticipated by the forward-looking
statements.  These factors include those referenced in Item 1, Business,
of the Corporation's Annual Report on Form 10-K for the period ending
December 31, 2002 under the heading "Forward-Looking Statements" or as may
be described from time to time in the Corporation's subsequent SEC
filings, and such factors are incorporated herein by reference.


ITEM 3.   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The following updated information should be read in conjunction with the
Corporation's 2002 Annual Report on Form 10-K.  Updated information
regarding the Corporation's use of derivative financial instruments is
contained in  Note 10, Notes to Financial Statements contained in Item 1
herein.

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

       Interest Rate Risk
       ___________________

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

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

The models used include measures of the expected repricing characteristics
of administered rate (NOW, savings and money market accounts) and non-rate
related products (demand deposit accounts, other assets and other
liabilities).  These measures recognize the relative insensitivity of
these accounts to changes in market interest rates, as demonstrated
through current and historical experiences.  However, during the second
quarter of 2003, the Corporation increased the proportion of these
accounts modeled as rate sensitive, in order to recognize the instability
of some of the recent balance growth in these accounts.  This modeling
treatment will be maintained until the incremental balances can be
observed across a more complete interest rate cycle.  In addition to
contractual payment information for most other assets and liabilities, the
models also include estimates of expected prepayment characteristics for
those items that are likely to materially change their payment structures
in different rate environments, including residential mortgage products,
certain commercial and commercial real estate loans and certain mortgage-
related securities.  Estimates for these sensitivities are based on
industry assessments and are substantially driven by the differential
between the contractual coupon of the item and current market rates for
similar products.

 42
This information is incorporated into a model that allows the projection
of future income levels in several different interest rate environments.
Earnings at risk is calculated by modeling income in an environment where
rates remain constant, and comparing this result to income in a different
rate environment, and then dividing this difference by the Corporation's
budgeted operating income before taxes for the calendar year.  Since
future interest rate moves are difficult to predict, the following table
presents two potential scenarios - a gradual increase of 100bp across the
entire yield curve over the course of a year (+25bp per quarter), and a
gradual decrease of 100bp across the entire yield curve over the course of
a year (-25bp per quarter) for the balance sheet as of  the indicated
dates:


                            Impact to Annual Pretax Income as of

                             September 30,   June 30,     March 31,   December 31, September 30,
                                  2003         2003         2003          2002         2002
                            --------------------------------------------------------------------
                                                                   
Hypothetical Change in Interest Rate
------------------------------------
   100 basis point gradual:

      Rise in rates                (1.1)%       (0.6)%        0.9 %        0.9 %        1.5 %

      Decline in rates             (1.6)%       (2.0)%       (1.4)%       (2.0)%       (2.0)%


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 also 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 the 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 asset and liability cash flows in different
market rate environments is the amount of fair value at risk from those
rate movements.  As of September 30, 2003, the fair value of equity at
risk for a gradual 100bp shift in rates has not changed materially since
December 31, 2002.

       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, however, fair values are difficult
to determine until an actual sale or liquidation transaction actually
occurs.

As of September 30, 2003, M&I Trust Services administered $61.2 billion in
assets and directly managed a portfolio of $14.5 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.


ITEM 4.   CONTROLS AND PROCEDURES

We maintain a set of disclosure controls and procedures that are designed
to ensure that information required to be disclosed by us in the reports
filed by us under the Securities Exchange Act of 1934, as amended, is
recorded, processed, summarized and reported within the time periods
specified in the SEC's rules and forms.  We carried out an evaluation,
under the supervision and with the participation of our management,
including our Chief Executive Officer and President and our Executive Vice
President and Chief Financial Officer, of the effectiveness of the design
and operation of our disclosure controls and procedures pursuant to Rule
13a-15 of the Exchange Act.  Based on that evaluation, our Chief Executive
Officer and President and our Executive Vice President and Chief Financial
Officer concluded that our disclosure controls and procedures are
effective as of the end of the period covered by this report.

There have been no changes in our internal control over financial
reporting identified in connection with the evaluation discussed above
that occurred during our last fiscal quarter that have materially
affected, or are reasonably likely to materially affect, our internal
control over financial reporting.

       The Audit Committee of the Board of Directors of Marshall & Ilsley
       Corporation has approved the following audit and non-audit services
       performed or to be performed for the Corporation by its independent
