__________
(1)  Common equivalent shares and related income were excluded from the
     computation of diluted loss per share for the three months ended December
     31, 2000 and June 30, 2000, as the effect would be antidilutive.
(2)  Includes trust preferred capital securities.
(3)  First quarter 2001 amounts include $40 million of charge-offs, which are
     not so classified in the Corporations GAAP financials because they are part
     of a portfolio that has been accounted for as loans held at a discount. The
     inclusion of these amounts in charge-offs more accurately reflects the
     performance of this portfolio. In the Corporation's consolidated financial
     statements, this item results in a higher provision in excess of net
     charge-offs.

N/M--Not meaningful.
N/A--Not available due to changes in segment composition; see Note 5 on page
     59 in the Corporation's 2000 Annual Report on Form 10-K.
(1) Beginning in the first quarter of 2001, employees on long-term disability
    and employees of unconsolidated subsidiaries are excluded.
(2) First quarter of each year favorably affected by tax-refund-anticipation
    loan activity.
(3) First quarter 2001 amounts include $40 million of charge-offs which are not
    so classified in the Corporations GAAP financials because they are part of a
    portfolio that has been accounted for as loans held at a discount. The
    inclusion of these amounts in charge-offs more accurately reflects the
    performance of this portfolio. In the Corporation's consolidated financial
    statements, this item results in a higher provision in excess of net charge-
    offs.

    Retail reported first quarter net income of $349 million, up 48% from the
year-ago quarter. This reflected the benefit of a $135 million, or 9%, increase
in revenue and a $115 million, or 11%, decline in expenses, which was partially
offset by higher provision for credit losses. Return on average equity was 23%,
compared with 18% in the year-ago quarter. First quarter results from both
periods included the seasonal impact from tax refund anticipation lending. The
efficiency ratio was 53% in the first quarter. While this benefited from
seasonal lending activity, progress in reducing expense is evidenced by the
decline from the year-ago efficiency ratio of 65%.

    Net interest income was $1.317 billion, up $81 million, or 7%, from the
year-ago quarter (excluding the impact of the sale of the consumer finance
business in the first quarter of 2000, net interest income increased 10%). This
increase was driven by wider loan spreads and a 5% increase in average loans
outstanding, partially offset by deposit margin compression. Loan growth was
concentrated in home equity loans, where average loans increased 22% from a year
ago. Average loans were unchanged from the 2000 fourth quarter, reflecting the
more disciplined approach toward managing the consumer credit portfolios that
was implemented last year. This has led to an improved portfolio mix by reducing
reliance on brokered home equity loans and auto leases. These portfolios are now
managed to maximize return on capital.

    Noninterest income was $360 million, up $54 million, or 18%, from the
year-ago quarter. The change reflected the absence of auto lease residual losses
in the first quarter, compared with $262 million in the 2000 fourth quarter and
$56 million in the year-ago quarter.

    Provision for credit losses was $244 million, up $77 million from the
year-ago quarter. Retail's managed net charge-offs totaled $206 million, an
increase from $98 million in the year-ago quarter and $159 million in the prior
quarter. The increased net charge-offs related to the expected increases from
brokered home equity loans as well as deterioration in certain parts of the
auto-lending portfolio. Retail's net charge-off ratio was 1.08%, up from 0.83%
in the prior quarter and 0.54% in the year-ago quarter.

    The allowance for loan losses increased $78 million, bringing the loan loss
reserve as a percent of loans to 1.21%, up from 1.10% at December 31, 2000, and
approximately 0.84% at March 31, 2000. Total Retail nonperforming assets
increased $323 million from a year ago, largely driven by a $266 million
increase in consumer nonperforming loans, which primarily represent 90-day loan
delinquencies. Compared with the prior quarter, Retail nonperforming assets
increased $41 million, or 4%.

    Noninterest expense was $887 million, down $115 million, or 11%, from the
year-ago quarter. This decrease reflected the positive impacts from
waste-reduction initiatives, reduced headcount in the lending and staff units
and the sale of the consumer finance business. Compared with the 2000 fourth
quarter, adjusted to exclude that quarter's significant items, noninterest
expense declined $78 million, or 8%.

  (1)  Beginning in the first quarter of 2001, employees on long-term disability
       and employees of unconsolidated subsidiaries are excluded.

     Commercial Banking reported first quarter net income of $159 million, down
$41 million, or 21%, from a year ago. This reflected the impact of a higher
provision for credit losses, partially offset by a 4% increase in revenue and a
5% decrease in expenses. The return on average equity was 10% in the first
quarter, down from 13% a year ago.

     As previously announced, Corporate Banking has been actively reviewing all
relationships in its portfolio to assess both overall exposure as well as
relationship profitability. The goal is to enhance overall profitability. These
reviews have resulted in the exiting of some customer relationships, but have
also produced additional business such as treasury management services and
capital market business. A direct result of this initiative was the reduction of
$3.9 billion of Corporate Banking loans. This decrease included $599 million in
loan sales, of which $375 million were nonperforming credits. First quarter
results from these sales included charge-offs of $89 million. The proceeds from
these sales were well within specifically established credit reserves for these
loans.

     Net interest income was $665 million, comparable to the year-ago quarter.
Total average loans of $80.6 billion were essentially unchanged from the
year-ago quarter. Middle Market Banking average loans increased $3.4 billion, or
11%, from the year-ago quarter and $1.3 billion, or 4%, from the 2000 fourth
quarter. Corporate Banking average loans decreased $3.2 billion, or 6%, from the
year-ago quarter, and $3.9 billion, or 8%, from the prior quarter. Impacting the
margin were slightly narrower loan spreads, the cost of carrying a higher level
of non-performing assets and the effect of an 8% decline in average deposits.
Compared with the 2000 fourth quarter, net interest income declined slightly,
reflecting wider loan spreads offset by the cost of carrying a higher level of
non-performing assets and the effect of a 7% decline in total average deposits.

     Noninterest income totaled $398 million, an increase of $44 million, or
12%, from the year-ago quarter. Trading income increased $24 million, or 45%,
from the 2000 first quarter and $20 million, or 35%, from the prior quarter,
reflecting healthy asset-backed finance, fixed income and derivative trading
activities. Non-deposit service charges increased $26 million, or 20%, from the
2000 first quarter, reflecting strong underwriting fees, corporate debt issuance
revenues and strong loan fees, partially offset by weak syndication activity.
Service charges on deposits decreased $3 million, or 2%, from the year-ago
quarter. Compared to the prior quarter, service charges on deposits declined $5
million, or 4%, reflecting the seasonality of treasury management services fees.

     The provision for credit losses was $264 million, a $132 million increase
from the year-ago quarter. Total net charge-offs were $249 million in the first
quarter, representing 1.23% of average commercial loans, up from 0.42% in the
year-ago quarter and down slightly from 1.24% in the prior quarter. Corporate
Banking net charge-offs were 1.61% of average loans in the first quarter, up
from 0.49% in the year-ago quarter and up from 1.58% in the prior quarter. The
year-over-year increase reflected the accelerated disposition of problem loans
through loan

sales. Middle Market net charge-offs were 0.73% of average loans in
the first quarter, compared to 0.31% in the year-ago quarter and 0.74% in the
prior quarter, reflecting overall economic weakness.

     The allowance for credit losses was $3.034 billion at March 31, 2001, up
from $3.020 billion at the end of the prior quarter. This represented 3.86% of
period-end loans and 197% of nonperforming loans, compared to 3.71% and 198%,
respectively, at December 31, 2000.

     At March 31, 2001, Corporate Banking nonperforming loans were $952 million,
down $113 million, or 11%, from December 31, 2000, reflecting the sale of
problem credits. Overall, increases in Corporate Banking nonperforming loans
have continued at approximately the same pace as in the prior two quarters.
Middle Market nonperforming loans increased $134 million, or 29%, to $592
million during the same time period, reflecting continued economic
deterioration.

     Noninterest expense totaled $544 million, down $26 million, or 5%, from the
year-ago quarter and $13 million, or 2%, from the prior quarter. Salaries and
benefits expense was down slightly from the year-ago quarter. Compared to the
prior quarter, salaries and benefits expense was up due to higher incentive
compensation. Other noninterest expense decreased $19 million, or 6%, from the
year-ago quarter and $42 million, or 13%, from the prior quarter, reflecting the
continued impact of waste reduction activities, partially offset by capital
markets infrastructure improvements. The efficiency ratio in the first quarter
was 51%, improved from 56% in the year-ago quarter.

 (1) Beginning in the first quarter of 2001, employees on long-term disability
     and employees of unconsolidated subsidiaries are excluded.

     First USA reported first quarter net income of $148 million, up $81 million
from the year-ago quarter and 10% from the 2000 fourth quarter. The year-over-
year increase primarily reflected the impact of lower expenses and managed
provision for credit losses, it was partially offset by an $89 million, or 5%,
decline in revenues. First quarter results represented a 1.46% pretax return on
outstandings, up from 0.63% in the year-ago and 1.28% in the 2000 fourth
quarter.

     Net interest income was $1.391 billion, down $134 million, or 9%, from the
year-ago quarter, reflecting lower fee revenue, a decline in average
outstandings and a narrower spread. Compared with the prior quarter, net
interest income decreased 2%, reflecting lower fee revenue.

                                      -11-
<PAGE>

     Average managed outstandings for the first quarter were $65.4 billion, down
3% from the year-ago period and essentially unchanged from the 2000 fourth
quarter average. End-of-period managed loans declined to $64.0 billion.
Attrition on mature vintage balances improved from the year-ago quarter and was
consistent with the previous quarter. While attrition improved, customer card
usage and related balances have declined, reflecting current economic
conditions. First USA opened 775,000 new accounts during the quarter, down
slightly from the 2000 fourth quarter level, and had 50.6 million cards issued
at quarter end. First USA continues to be a leader in online card marketing and
customer service with over 2.4 million registered users of its website,
FirstUSA.com.

     Noninterest income was $309 million, up $45 million, or 17%, from the prior
year. This increase primarily reflected the difference in securitization
activity between the periods. Noninterest income was virtually unchanged from
the 2000 fourth quarter. The difference in securitization activity was offset by
lower sales of fee-based products and seasonally lower interchange revenue.

     The managed provision for credit losses was $950 million, down $19 million
from the year-ago quarter. The managed net charge-off rate increased to 5.81%
from 5.78%, reflecting the increased average age of the portfolio resulting from
recent periods of lower new account growth and average outstandings. Managed net
charge-offs were up from the 2000 fourth quarter, in line with expectations. The
managed 30-day and 90-day delinquency rates were 4.33% and 2.02%, respectively,
up from 4.08% and 1.91%, in the year-ago quarter, but down from 4.51% and equal
to 2.02%, respectively, in the prior quarter, reflecting normal seasonality.

     Noninterest expense totaled $514 million, down $201 million, or 28%, from
the prior year, reflecting the positive impact of waste-reduction initiatives,
such as lower headcount, improved operating efficiency and reduced operating
losses. The decline from the year-ago quarter also reflected the sale of the
international operations in the 2000 second quarter, lower operating costs and a
decrease in internally allocated costs related to a mid-year 2000 change in
allocation methodology. Noninterest expense declined $123 million from the 2000
fourth quarter, which included $46 million of special items. The decrease in
noninterest expense reflected lower expenses for purchased and professional
services, as well as reduced fraud and operating losses. None of the noninterest
expense reductions related to marketing expense, which was up from both the
year-ago and 2000 fourth quarter periods. The efficiency ratio for the current
period was 30%, down from 40% in the prior year and 37% from the 2000 fourth
quarter.

 (1)  Beginning in the first quarter of 2001, employees on long-term disability
      and employees of unconsolidated subsidiaries are excluded.

     Investment Management reported first quarter net income of $82 million, a
slight increase from the year-ago quarter. This reflected a $24 million, or 6%,
increase in revenue, which was partially offset by higher expenses. Compared
with the prior quarter, net income remained flat, reflecting the continued
impact of volatile and difficult market conditions.

     Period-end assets under management increased to $131.5 billion, up slightly
from the year-ago and 2000 fourth quarters. One Group(R) mutual fund assets
under management increased to $71.0 billion in the first quarter, a 6% increase
year-over-year and a 1% increase from the prior quarter. Overall, One Group(R)
net fund flows remained positive. In the first quarter, the mix of assets under
management changed. Money market assets increased significantly, fixed income
assets increased modestly and equity assets declined from both the year-ago and
the 2000 fourth quarters.

     Compared with the first quarter of 2000, the $7.0 billion decline in assets
under management from the Private Client Services segment was partially offset
by a $5.9 billion increase in assets under management in the Institutional
segment.

     During the first quarter, overall One Group(R) fund performance remained
strong. The assets in funds rated 4 and 5 by Morningstar increased from 49% in
the fourth quarter of 2000 to 62% in the first quarter of 2001, with 95% of
assets in funds rated three stars or higher. The One Group(R) Diversified Mid
Cap fund was cited by Mutual Fund Magazine as one of the 20 best
performance-tested funds for 2001, based on its comparison of more than 6,000
diversified stock and balanced funds in the Morningstar database. Also in the
quarter, IMG launched its 50th fund and third sector fund, the One Group(R)
Health Sciences fund.

     Net interest income totaled $104 million, up $4 million, or 4%, from the
year-ago period. Higher spread income associated with the 6% increase in average
loans was partially offset by the effect of the 6% decrease in average deposits.
Compared with the prior quarter, net interest income was unchanged.

     Noninterest income was $307 million, an increase of $20 million, or 7%,
from the year-ago quarter. Beginning in the 2000 fourth quarter, fees associated
with the in-house administration of the One Group(R) mutual funds were recorded
as revenue, with a corresponding increase in expense. Prior to that, a
third-party administrator incurred such fees and expenses, which totaled $24
million in the first quarter. Excluding the impact of this change, as well as
the sale of the land trust business in the prior-year quarter, noninterest
income increased 4% from a year ago.

     Compared to the prior quarter, noninterest income increased $7 million, or
2%. Excluding the effect of the above-mentioned change in the administration of
the One Group(R) funds, noninterest income was essentially flat

                                      -15-
<PAGE>

versus the prior quarter, reflecting the previously mentioned shift in the value
and mix of assets under management.

     Retail brokerage sales of mutual funds and annuities were $1.1 billion in
the first quarter, down $55 million, or 5%, from the year-ago quarter and up
$199 million, or 21%, from the prior quarter, despite the weaker market
conditions. The mix of product sold reflected a shift by retail investors to
annuities.

     Noninterest expense of $277 million increased $20 million, or 8%, from the
year-ago quarter. Excluding the expenses associated with the administration of
the One Group(R) funds, noninterest expense declined slightly from a year ago.
Noninterest expense increased $9 million, or 3%, from the 2000 fourth quarter
due principally to that quarter's lower incentive expense.

(1)   Beginning in the first quarter of 2001, employees on long-term disability
      and employees of unconsolidated subsidiaries are excluded.

     Corporate Investments reported a first quarter net loss of $29 million,
compared with net income of $141 million in the year-ago quarter and a net loss
of $15 million in the 2000 fourth quarter. First quarter results were negatively
impacted by significant declines in equity valuations, while various leasing
strategies continued to provide stable core performance in the current quarter,
consistent with the year-ago and prior quarters.

     Net interest income of $26 million declined $9 million, or 26%, from the
year-ago quarter, due to the funding of investments that does not yield interest
income.

     Noninterest income declined $272 million from the year-ago quarter to a net
expense of $87 million, reflecting valuations of marketable equity securities,
mostly held through investments in funds. The Corporation currently holds
approximately $300 million in marketable equity securities.

     Noninterest expense of $19 million declined $20 million, or 51%, from the
year-ago quarter reflecting lower incentive-based compensation and stronger
expense control. Noninterest expense increased $12 million from the $7 million
reported in the 2000 fourth quarter, driven primarily by the fourth quarter's
lower incentive compensation.

     and employees of unconsolidated subsidiaries are excluded.

     Corporate/Unallocated includes Treasury, unallocated Corporate expenses and
any gain or loss from Corporate transactions. Included in first quarter results
were gains of $73 million pre-tax ($43 million after tax) on the sale of the
Corporation's portion of the equity position in EquiServe Limited Partnership
and on the sale of the Corporation's investment in Star Systems, an ATM network.
Excluding these gains, the first quarter recorded a net loss of $73 million.

                              CONSOLIDATED RESULTS

Summary of Financial Results

     The Corporation reported net income of $679 million, or $0.58 per diluted
share, for the first quarter of 2001, compared to net income of $689 million, or
$0.60 per diluted share, for the first quarter of 2000.

 Net Interest Income

     Net interest income includes spreads on earning assets as well as items
such as loan fees, cash interest collections on problem loans, dividend income,
interest reversals, and income or expense on derivatives used to manage interest
rate risk. Net interest margin measures how efficiently the Corporation uses its
earning assets and underlying capital.

     In order to understand fundamental trends in net interest income, average
earning assets and net interest margins, it is useful to analyze financial
performance on a managed portfolio basis, which adds data on securitized loans
to reported data on loans as presented below:

</TABLE>

     Lower net interest income and the corresponding decline in the net interest
margin in the 2001 first quarter as compared to the year ago quarter reflected
narrower spreads earned on loans and other investments. This was primarily
driven by a decline in the average yield earned on credit card receivables and
an increase in the average rate paid on deposits.

<PAGE>

     Managed noninterest income decreased 8% from the year-ago period to $1.39
billion, primarily reflecting net losses of $96 million on equity securities in
the current quarter versus gains of $158 million in the first quarter of 2000,
partially offset by higher miscellaneous income. The first quarter 2001 net
losses on equity securities primarily reflected lower valuations of investments
in private equity funds, while the 2000 first quarter net gains reflected
favorable market conditions.

     Managed non-deposit service charges increased 6% to $411 million in the
2001 first quarter compared with the year-ago quarter, due to strong
underwriting fees, corporate debt issuance revenues and other loan product fees.

     Managed credit card revenue increased 13% to $307 million in the 2001 first
quarter compared with the same period of 2000, reflecting increased
securitization activity in the 2001 period, partially offset by lower service
fee revenue and lower interchange revenue in the 2001 first quarter.

     Other activities generated income of $188 million in the first quarter of
2001, compared with $113 million of income in the first quarter of 2000. The 66%
increase in other income primarily reflected gains of $73 million on the sale of
ownership interests in EquiServe and Star Systems.

Noninterest Expense

     Noninterest expense for the 2001 first quarter decreased 16% to $2.2
billion compared with the year-ago period.

(1)  Beginning in the first quarter of 2001, long-term disability employees and
     employees of unconsolidated subsidiaries are excluded. Excluding this
     change in methodology, headcount declined 328 in the first quarter of 2001.

     Components of noninterest expense that are primarily related to a single
business segment are discussed within that business segment rather than the
consolidated section.

     Salary and benefit costs, including severance charges, were $982 million in
the first quarter of 2001, down 11% from $1.1 billion in the year-ago period.
The decrease reflected expense savings from reduced headcount, lower incentive
compensation and cost reductions associated with the modification of the
Corporation's 401(k) plan.

<PAGE>

     Equipment expense in the first quarter of 2001 decreased $34 million, or
22%, from the year ago period, primarily due to decreased furniture and
equipment rental and lower depreciation expense.

     Outside service fees and processing expense decreased by $153 million, or
38%, in the first quarter of 2001 compared to the year-ago period. This
significant decrease reflected reduced consulting expenses, lower costs for
certain purchased services, data processing credits and other benefits from the
Corporation's waste reduction initiatives.

     Marketing and development expense decreased 9% in the first quarter 2001 to
$205 million, compared with the 2000 first quarter, as expense reductions in the
Retail line of business more than offset increased expenditures for First USA.

     Other intangible amortization expense decreased 49% in the 2001 first
quarter when compared with the year-ago period, due to impairments associated
with purchased credit card relationships recorded in 2000 that reduced the
ongoing level of related amortization expense.

     Other operating expense decreased $99 million in the first quarter of 2001,
compared with the year-ago period, primarily attributable to reduced legal
provisions and the Corporation's waste reduction initiatives to lower expenses
for such items as travel and entertainment, recruiting and other miscellaneous
items.

     The Corporation achieved its goal of $500 million in annual expense savings
from waste reduction efforts, while at the same time increasing spending in
certain targeted areas such as systems conversions. First quarter 2001 results
reflected expense levels that were $85 million after-tax ($125 million pre-tax)
below the ongoing expense run rate level due to certain one-time benefits,
timing of expense, and planned increases in conversion and marketing expenses.

                                 RISK MANAGEMENT

     The Corporation's various business activities generate liquidity, market,
credit and operating risks:

     .   Liquidity risk is the possibility of being unable to meet all
         current and future financial obligations in a timely manner.

     .   Market risk is the possibility that changes in future market rates or
         prices will make the Corporation's positions less valuable.

     .   Credit risk is the possibility of loss from borrowers and
         counterparties failing to perform according to the terms of a
         transaction.

     .   Operating risk, among other things, includes the risk of fraud by
         employees or persons outside the Corporation, the execution of
         unauthorized transactions by employees, and errors relating to
         transaction processing and systems.

<PAGE>

     The following discussion of Bank One's risk management processes focuses
primarily on developments since December 31, 2000. The Corporation's risk
management processes for liquidity, market, credit and operating risks are
described in detail in the Corporation's 2000 Annual Report on Form 10-K,
beginning on page 20.

                           LIQUIDITY RISK MANAGEMENT

     Liquidity is managed in order to preserve stable, reliable and
cost-effective sources of cash to meet all current and future financial
obligations in a timely manner. The Corporation considers strong capital ratios,
credit quality and core earnings essential to retaining high credit ratings and,
consequently, cost-effective access to market liquidity. In addition, a
portfolio of liquid assets, consisting of federal funds sold, deposit placements
and selected highly marketable investment securities, is maintained to meet
short-term demands on liquidity.

     The Corporation's ability to attract wholesale funds on a regular basis and
at a competitive cost is fostered by strong ratings from the major credit rating
agencies. The Corporation and its principal banks had the following long- and
short-term debt ratings:

                             MARKET RISK MANAGEMENT

Overview

     Market risk refers to potential losses arising from changes in interest
rates, foreign exchange rates, equity prices and commodity prices, as well as
the correlation among these factors and their volatility. The portfolio effect
of engaging in diverse trading activities helps reduce the potential impact of
market risk on earnings. Through its trading activities, the Corporation strives
to take advantage of profit opportunities available in interest and exchange
rate movements. In asset and liability management activities, policies are in
place that are designed to closely manage structural interest rate and foreign
exchange rate risk.

 Value-At-Risk - Trading Activities

     The Corporation has developed policies and procedures to manage market risk
through a value-at-risk measurement and control system, through a stress testing
process and through dollar trading limits. The objective of this process is to
quantify and manage market risk in order to limit single and aggregate exposures

     Value-at-risk is intended to measure the maximum fair value the Corporation
could lose on a trading position, given a specified confidence level and time
horizon. Value-at-risk limits and exposure are monitored on a daily basis for
each significant trading portfolio. Stress testing is similar to value-at-risk
except that the confidence level is geared to capture more extreme, less
frequent market events.

     The Corporation's value-at-risk calculation measures potential losses in
fair value using a 99% confidence level and a one-day time horizon. This equates
to 2.33 standard deviations from the mean under a normal distribution. This
means that, on average, daily profits and losses are expected to exceed
value-at-risk one out of every 100 overnight trading days. Value-at-risk is
calculated using various statistical models and techniques for cash and
derivative positions, including options.

</TABLE>

     The activities covered by the table above reflect trading and other
activities, including certain overseas balance sheet positions that are managed
principally as trading risk. Value-at-risk from commodity price risk was
immaterial.

     Interest rate risk was the predominant type of market risk incurred during
the first quarter of 2001. At March 31, 2001, approximately 83% of primary
market risk exposures were related to interest rate risk. Exchange rate, equity
and commodity risks accounted for 17% of primary market risk exposures.

Structural Interest Rate Risk Management

     Interest rate risk exposure in the Corporation's "core" business
(non-trading) activities, i.e., asset/liability management ("ALM") position, is
a result of reprice, option and basis risks associated with on- and off-balance
sheet positions. The ALM position is measured and monitored using sophisticated
and detailed risk management tools, including earnings simulation modeling and
economic value of equity sensitivity analysis, to capture both near-term and
longer-term interest rate risk exposures.

     Earnings simulation analysis, or earnings-at-risk, measures the sensitivity
of pretax earnings to various interest rate movements. The base-case scenario is
established using the implied forward curve. The comparative scenarios assume an
immediate parallel shock of the forward curve in increments of +/- 100 basis
point rate movements. Numerous other scenarios are analyzed, including more
gradual rising or declining rate changes and non-parallel rate shifts. Estimated
earnings for each scenario are calculated over a 12-month and 24-month horizon.
The interest rate scenarios are used for analytical purposes and do not
necessarily represent Management's view of future market movements. Rather,
these are intended to provide a measure of the degree of volatility interest
rate movements may introduce into the earnings and economic value of the
Corporation.

     The table below shows the Corporation's pretax earnings sensitivity profile
as of March 31, 2001 and December 31, 2000:

</TABLE>

     The increase in earnings sensitivity during the quarter is primarily due to
a longer duration of the Corporation's earning assets.

     Modeling the sensitivity of earnings to interest rate risk is highly
dependent on the numerous assumptions embedded in the model. While the earnings
sensitivity analysis incorporates Management's best estimate of interest rate
and balance sheet dynamics under various market rate movements, the actual
behavior and resulting earnings impact will likely differ from that projected.

Foreign Exchange Risk Management

     Whenever possible, foreign currency-denominated assets are funded with
liability instruments denominated in the same currency. If a liability
denominated in the same currency is not immediately available or desired, a
forward foreign exchange or cross-currency swap contract is used to fully hedge
the risk due to cross-currency funding.

                                      -23-
<PAGE>

     To minimize the capital impact of translation gains or losses measured on
an after-tax basis, the Corporation uses forward foreign exchange contracts to
hedge the exposure created by investments in overseas branches and subsidiaries.

                             CREDIT RISK MANAGEMENT

     In conducting its business operations, the Corporation is exposed to the
risk that borrowers or counterparties may default on their obligations to the
Corporation. These transactions create credit exposure that is reported both on
and off the balance sheet. On-balance sheet credit exposure includes such items
as loans. Off-balance sheet credit exposure includes unfunded credit commitments
and other credit-related financial instruments.

     In order to meet its credit risk management objectives, the Corporation
maintains a risk profile that is diverse in terms of borrower concentrations,
product type, and industry and geographic concentrations. Additional
diversification of the Corporation's exposure is accomplished through
syndication of credits, participations, loan sales, securitizations and other
risk-reduction measures.

                            OPERATING RISK MANAGEMENT

     In addition to being exposed to liquidity, market and credit risk, the
Corporation is also exposed to numerous types of operating risk. Operating risk
generally refers to the risk of loss resulting from the Corporation's
operations, including, but not limited to, the risk of fraud by employees or
persons outside the Corporation, the execution of unauthorized transactions by
employees, errors relating to transaction processing and systems, and other
breaches of the internal control system and compliance requirements. This risk
of loss also includes the potential legal actions that could arise as a result
of the operational deficiency or as a result of noncompliance with applicable
regulatory standards.

Commercial Real Estate

     The commercial real estate segment of the portfolio is the largest product
category and consists primarily of loans secured by real estate as well as
certain loans that are real estate-related. This exposure includes loans and
commitments that finance both owner-occupied and investment properties/projects.

     Commercial real estate lending is conducted in several lines of business,
with the majority of these loans originated by Corporate Banking primarily
through its specialized National Commercial Real Estate Group. This group's
focus is lending to targeted regional and national real estate developers,
homebuilders and REITs/REOCs. As of March 31, 2001, this group's loan
outstandings totaled $9.4 billion, or 42%, of the commercial real estate
portfolio. Middle Market Banking originates primarily owner-occupied real estate
loans located in the various markets served by Middle Market bankers. At March
31, 2001, commercial real estate loans totaled $22.5 billion, or 23.0% of total
commercial loans, compared with $22.5 billion, or 22.4% of commercial loans, at
December 31, 2000.

     The table below presents commercial real estate loans for the National

Nonperforming Assets

     The Corporation defines nonperforming loans as commercial loans that are
impaired and/or on nonaccrual status, consumer loans (i.e., non-credit card)
greater than 90 days past due and restructured loans. These loans, along with
assets primarily consisting of foreclosed real estate, represent nonperforming
assets.

business and total nonperforming assets for the periods indicated:

     Despite the Corporation's diversified Commercial Banking portfolio, the
Corporation has experienced credit quality deterioration in a number of distinct
market segments. A weakening economy, among other things, had led to an increase
in nonperforming loans. The Corporation has established processes for
identifying potential problem areas of the portfolio, which currently include
exposure to leveraged lending and acquisition finance activities, healthcare,
automotive parts and manufacturing, business finance and leasing, professional
services, miscellaneous transportation services, selected utilities,
telecommunications, and companies engaged in ongoing asbestos litigation. The
Corporation will continue its enhanced focus on identifying and monitoring these
potential exposure areas.

     part of a portfolio that has been accounted for as loans held at a
     discount, but viewed for management purposes as charge-offs. In
     Management's view, the inclusion of these amounts in charge-offs more
     accurately reflects the performance of the portfolio. See Retail LOB

Allowance for Credit Losses

     The allowance for credit losses is maintained at a level that in
Management's judgment is adequate to provide for estimated probable credit
losses inherent in various on- and off-balance sheet financial instruments. This
process includes deriving probable loss estimates that are based on historical
loss rates, portfolio stress testing of probable loss estimates and Management's
judgment. The reserve is based on ranges of estimates and is intended to be
adequate but not excessive. Each quarter, reserves are formally estimated by
each line of business and reviewed by the Corporate Risk Management Department
and Senior Management.

     The following table shows the components of, by line of business, the
change in the Corporation's allowance for credit losses for the periods
indicated:

                       Derivative Financial Instruments

     The Corporation uses a variety of derivative financial instruments in its
trading, asset and liability management, and corporate investment activities, as
well as to manage certain currency translation exposures of foreign operations.
These instruments include interest rate, currency, equity and commodity swaps,
forwards, spot, futures, options, caps, floors, forward rate agreements, and
other conditional or exchange contracts, and include both exchange-traded and
over-the-counter contracts.

Accounting for Derivative Financial Instruments

     Effective January 1, 2001, the Corporation adopted Statement of Financial
Accounting Standards ("SFAS") No. 133 "Accounting for Derivative Instruments and
Hedging Activities" as amended. The new standard significantly changed the
accounting treatment for interest rate and foreign exchange derivatives the
Corporation uses in its asset and liability management ("ALM") activities. The
new accounting treatment for ALM derivatives is described below. Cash flows from
derivative financial instruments are reported net as operating activities.

Trading Derivative Instruments

     The Corporation's accounting policies for derivatives used in trading
activities have not changed as the result of SFAS No. 133. A detailed discussion
of accounting for trading derivative instruments is presented in the
Corporation's 2000 Annual Report on Form 10-K.

ALM Derivative Instruments

     Derivative financial instruments used in ALM activities, principally
interest rate swaps, are classified as fair value hedges or cash flow hedges and
are required to meet specific criteria. Such interest rate swaps are designated
as ALM derivatives, and are linked to and adjust the interest rate sensitivity
of a specific asset, liability, firm commitment, or anticipated transaction or a
specific pool of transactions with similar risk characteristics. Interest rate
swaps that do not meet these and the following criteria are designated as
derivatives used in trading activities and are accounted for at estimated fair
value.

     Fair Value Hedge (primarily hedges of fixed rate interest-bearing
instruments) -- The change in fair value of both the hedging derivative and
hedged item is recorded in current earnings. If a hedge is dedesignated prior
to maturity, previous adjustments to the carrying value of the hedged item are
recognized in earnings to match the earnings recognition pattern of the hedged
item (e.g., level yield amortization if hedging an interest-bearing instrument).

     Cash Flow Hedge (primarily hedges of variable rate interest-bearing
instruments) -- The effective portion of the change in fair value of the hedging
derivative is recorded in Accumulated Other Adjustments to Stockholders' Equity
("AOASE") and the ineffective portion directly in earnings. These amounts are
reclassified into earnings

                                      -29-
<PAGE>

in a manner consistent with the earnings pattern of the underlying hedged item
(generally, reflected in interest expense). The total amount of such
reclassification into earnings is projected to be charges of $82 million after-
tax over the next twelve months. If a hedge is dedesignated prior to maturity,
previous adjustments to AOASE are recognized in earnings to match the earnings
recognition pattern of the hedged item (e.g., level yield amortization if
hedging an interest-bearing instrument) or immediately recognized in current
earnings of the hedged item is sold.

     Interest income or expense on most ALM derivatives used to manage interest
rate exposure is recorded on an accrual basis, as an adjustment to the yield of
the linked exposures over the periods covered by the contracts. This matches the
income recognition treatment of that exposure, generally assets or liabilities
carried at historical cost, that are recorded on an accrual basis. If an
interest rate swap is terminated early or dedesignated as an ALM derivative, any
unrecognized gain or loss at that point in time is deferred and amortized as an
adjustment of the yield on the linked interest rate exposure position over the
remaining periods originally covered by the swap. If all or part of a linked
position is terminated, e.g., a linked asset is sold or prepaid, or if the
amount of an anticipated transaction is likely to be less than originally
expected, then the related pro rata portion of any unrecognized gain or loss on
the swap is recognized in earnings at that time, and the related pro rata
portion of the swap is subsequently accounted for at estimated fair value.

Hedges of the Net Investment in Foreign Operations

     In order to minimize the capital impact of translation gains or losses
measured on an after-tax basis, the Corporation uses forward foreign exchange
contracts to hedge the exposure relating to the net investment in foreign
operations. The effective portion of the change in fair value of the hedging
derivative is recorded in AOASE as part of the cumulative translation
adjustment. The amount of after-tax gains included in the cumulative translation
adjustment during the three months ended March 31, 2001, related to hedges of
the foreign currency exposures of net investments in foreign operations, totaled
$7 million.

Income Resulting from Derivative Financial Instruments

     The Corporation uses interest rate derivative financial instruments to
reduce structural interest rate risk and the volatility of net interest margin.
Net interest margin reflects the effective use of these derivatives. Without
their use, net interest income would have been lower by $7 million in the first
quarter 2001 and lower by $11 million in the first quarter of 2000.

     Recognition of hedge ineffectiveness for cash flow and fair value hedges in
the quarter ended March 31, 2001, was insignificant. No component of a hedging
derivative instrument's gain or loss is excluded from the assessment of fair
value and cash flow hedge effectiveness.

Credit Exposure Resulting from Derivative Financial Instruments

     Credit exposure from derivative financial instruments arises from the risk
of a counterparty default on the derivative contract. The amount of loss created
by the default is the replacement cost or current fair value of the defaulted
contract. The Corporation utilizes master netting agreements whenever possible
to reduce its credit exposure from customer defaults. These agreements allow the
netting of contracts with unrealized losses against contracts with unrealized
gains to the same counterparty, in the event of a counterparty default.

     The table below shows the impact of these master netting agreements:

     Current credit exposure represents the total loss the Corporation would
have suffered had every counterparty been in default on those dates. These
amounts are adjusted by the unrealized and unrecognized gains and losses on
derivatives used in asset and liability management activities to arrive at the
balance sheet exposure.

Asset and Liability Management Derivatives

     Access to the derivatives market is an important element in maintaining the
Corporation's desired interest rate risk position. In general, the assets and
liabilities generated through ordinary business activities do not naturally
create offsetting positions with respect to repricing, basis or maturity
characteristics. Using derivative instruments, principally plain vanilla
interest rate swaps (ALM swaps), the interest rate sensitivity of specific
off-balance sheet transactions, as well as pools of assets, is adjusted to
maintain the desired interest rate risk profile.

     At March 31, 2001, the notional value of ALM interest rate swaps tied to
specific assets or liabilities, firm commitments and forecasted transactions
totaled $12.6 billion as follows:

</TABLE>

     Interest rate swaps used to adjust the interest rate sensitivity of
securities and funds borrowed will not need to be replaced at maturity, since
the corresponding asset or liability will mature along with the swap. Interest
rate swaps designated as an interest rate related hedge of an existing fixed
rate asset or liability are fair value type hedges. Conversely, interest rate
swaps designated as an interest rate related hedge of an existing variable rate
asset or liability are cash flow type hedges. Management designates interest
rate swaps as hedges of both fixed and variable rate assets and liabilities
interchangeably. The type of hedge for accounting purposes is not a strategic
consideration. The Corporation has an insignificant amount of hedges involving
forecasted transactions and firm commitments, and no non-derivative instruments
are designated as a hedge.

                              Loan Securitizations

     Investors in the beneficial interests of the securitized loans have no
recourse against the Corporation if cash flows generated from the securitized
loans are inadequate to service the obligations of the SPE. To help ensure that
adequate funds are available in the event of a shortfall, the Corporation is
required to deposit funds into cash spread accounts if excess spread falls below
certain minimum levels. Spread accounts are funded from excess spread that would
normally be returned to the Corporation. In addition, various forms of other
credit enhancement are provided to protect more senior investor interests from
loss. Credit enhancements associated with credit card securitizations, such as
cash collateral or spread accounts, totaled $533 million at March 31, 2001, and
are classified on the balance sheet as other assets.

     For further discussion of Bank One's loan securitization process and other
related disclosures, see pages 41-42 and pages 63-65 of the Corporation's 2000
Annual Report on Form 10-K.

     The key weighted average economic assumptions used to estimate the fair
value of the interest-only strip and seller's interest as of March 31, 2001,
were unchanged from December 31, 2000. The asset values of the seller's
interest, interest-only strip and credit enhancements are periodically reviewed
for other-than-temporary impairment.

                               CAPITAL MANAGEMENT

     Capital represents the stockholders' investment on which the Corporation
strives to generate attractive returns. It is the foundation of a cohesive risk
management framework and links return with risk. Capital supports business
growth and provides protection to depositors and creditors.

     In conjunction with the annual financial planning process, a capital plan
is established to ensure that the Corporation and all of its subsidiaries have
capital structures consistent with prudent management principles and regulatory
requirements.

Economic Capital

     An important aspect of risk management and performance measurement is the
ability to evaluate the risk and return of a business unit, product or customer
consistently across all lines of business. The Corporation's economic capital
framework facilitates this standard measure of risk and return. Business units
are assigned capital consistent with the underlying risks of their product set,
customer base and delivery channels. For a more detailed discussion of Bank
One's economic capital framework, see page 44 of the Corporation's 2000 Annual
Report on Form 10-K.

Selected Capital Ratios

     The Corporation aims to maintain regulatory capital ratios, including those
of the principal banking subsidiaries, in excess of the well-capitalized
guidelines under federal banking regulations. The Corporation has maintained a
well-capitalized regulatory position for the past several years.

     The tangible common equity to tangible managed assets ratio is also
monitored. This ratio adds securitized credit card loans to reported total
assets and is calculated net of total intangible assets. The tangible common
equity to tangible managed assets ratio was 5.6% at March 31, 2001, up from 5.5%
at December 31, 2000. Tier 1 and Total Capital ratios were 7.8% and 11.2% and
7.3% and 10.8%, respectively, at March 31, 2001, and December 31, 2000.

     The Corporation's capital ratios that adhere to regulatory guidelines
appear in the table below:

Dividend Policy

     The Corporation's common dividend policy reflects its earnings outlook,
desired payout ratios, the need to maintain an adequate capital level and
alternative investment opportunities. The common dividend payout ratio is
targeted in the range of 25% - 30% of earnings over time. On January 16, 2001,
the Corporation declared its quarterly common cash dividend of 21 cents per
share, payable on April 1, 2001. The common stock dividend declared for the
first quarter of 2000 was 42 cents per share. The decrease from the year-ago
period reflects a 50% reduction of the quarterly dividend rate from 42 cents per
share to 21 cents per share in the third quarter of 2000.

Double Leverage

     Double leverage is the extent to which the Corporation's resources is used
to finance investments in subsidiaries. Double leverage was 106% at March 31,
2001, and 108% at December 31, 2000. Trust Preferred Capital Securities of
$2.790 billion for the first quarter of 2001 and $1.578 billion in the prior
year quarter were included in capital for purposes of this calculation.

                           FORWARD-LOOKING STATEMENTS

    Management's Discussion and Analysis included herein contains certain
forward-looking statements within the meaning of the Private Securities
Litigation Reform Act of 1995. In addition, the Corporation may make or approve
certain statements in future filings with the Securities and Exchange
Commission, in press releases, and in oral and written statements made by or
with the Corporation's approval that are not statements of historical fact and
may constitute forward-looking statements. Forward-looking statements may relate
to, without limitation, the Corporation's financial condition, results of
operations, plans, objectives, future performance or business.

    Forward-looking statements can be identified by the fact that they do not
relate strictly to historical or current facts. They often include the words
"believes", "anticipates", "expects", "intends", "plans", "estimates", "targets"
or words of similar meaning or future or conditional verbs such as "will",
"would", "should", "could" or "may".

     Forward-looking statements involve risks and uncertainties. Actual
conditions, events or results may differ materially from those contemplated by a
forward-looking statement. Factors that could cause this difference - many of
which are beyond the Corporation's control - include the following, without
limitation:

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                     BANK ONE CORPORATION and Subsidiaries

Note 1--Summary of Significant Accounting Policies

     Consolidated financial statements of BANK ONE CORPORATION and Subsidiaries
(the "Corporation" or "Bank One") have been prepared in conformity with
generally accepted accounting principles. Management is required to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes that could differ from actual results. Certain
prior-year financial statement information has been reclassified to conform to
the current year's financial statement presentation.

     Although the interim amounts are unaudited, they do reflect all adjustments
that, in the opinion of management, are necessary for a fair presentation of the
results of operations for the interim periods. All such adjustments are of a
normal, recurring nature. Because the results from commercial banking operations
are so closely related and responsive to changes in economic conditions, fiscal
policy and monetary policy, and because the results for the investment security
and trading portfolios are largely market-driven, the results for any interim
period are not necessarily indicative of the results that can be expected for
the entire year.

     These financial statements should be read in conjunction with the
consolidated financial statements and related notes included in the
Corporation's Annual Report on Form 10-K for the year ended December 31, 2000.

Note 2--New Accounting Pronouncements

Accounting for Transfers and Servicing of Financial Assets and Liabilities

     In September 2000, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 140, "Accounting for Transfers and Servicing of Financial Assets and
Liabilities" SFAS No. 140 revises certain criteria promulgated in previous
accounting literature (SFAS No. 125) regarding the accounting for
securitizations and other transfers of financial assets and collateral, and
requires additional disclosures concerning these activities. The Corporation is
currently evaluating the effects of adopting SFAS No. 140 and its
interpretations and related guidance, on its current accounting policies for
securitizations and other transfers of financial assets. The Corporation
currently does not believe that the impact, if any, of adopting SFAS No. 140
will be significant to its financial position or net income.

Accounting for Derivative Instruments and Hedging Activities

     Effective January 1, 2001, the Corporation adopted SFAS No. 133 "Accounting
for Derivative Instruments and Hedging Activities", as amended. The new standard
significantly changed the accounting treatment for interest rate and foreign
exchange derivatives the Corporation uses in its asset and liability management
activities. The Corporation's accounting for derivatives used in trading
activities has not changed as the result of SFAS No. 133. Hedging derivatives
are now recognized on the balance sheet at fair value as either assets or
liabilities. Hedge ineffectiveness, if any, is calculated and recorded in
current earnings. The accounting for the effective portion of the change in
value of a hedging derivative is based on the nature of the hedge. See
"Derivative Financial Instruments" on page 29 for detailed information on the
Corporation's strategy in using derivative instruments in its asset and
liability management and trading activities, as well as the new accounting
principles and disclosure for derivative instruments pursuant to SFAS No. 133.

Note 3--Earnings per Share

     Basic EPS is computed by dividing income available to common stockholders
by the average number of common shares outstanding for the period. Except when
the effect would be antidilutive, the diluted EPS calculation includes shares
that could be issued under outstanding stock options and the employee stock
purchase plans, and common shares that would result from the conversion of
convertible preferred stock and convertible debentures. Interest on convertible
debentures (net of tax) is added to net income, since this interest would not be
paid if the debentures were converted to common stock.

Note 4--Pending Acquisition

     On April 9, 2001, the Corporation entered into a definitive agreement to
purchase the $8 billion credit card business of Wachovia Corporation. The
business includes 2.8 million customer accounts. The transaction also includes a
long-term agreement to market consumer credit cards to Wachovia's retail
customers, with servicing being provided by First USA. The transaction, to be
paid entirely of cash consideration, is expected to close in the 2001 second
quarter, subject to regulatory review.

Note 5--Second Quarter 2000 Restructuring Charge

     The Corporation recorded restructuring costs of $233 million in the second
quarter of 2000 related to the restructuring of certain of its retail businesses
as well as exit costs associated with specific decisions made to abandon
identified facilities, equipment and application software. The initial
restructuring charge included personnel-related items consisting primarily of
severance costs related to identified staff reductions totaling 2,200 positions
in the Retail line of business that would be implemented when assets were sold.
Also included in the initial charge were asset writedowns including leasehold
write-offs related to leased properties following the decision to abandon such
facilities, as well as the write-offs of fixed assets and capitalized software,
for which similar decisions were made. In the 2000 fourth quarter, Management
reduced its estimate of staff reductions to 1,257 positions as a result of the
decision not to dispose of the assets previously identified for sale.

     The following table summarizes the activity relating to this restructuring
charge reserve during the 2001 first quarter (in millions):

Note 6--Business Segments

     The information presented on page 2 is consistent with the content of
operating segments data provided to the Corporation's management. The
Corporation's management currently does not use product group revenues to assess
consolidated results. Aside from investment management and insurance products,
product offerings are tailored to specific customer segments. As a result, the
aggregation of product revenues and related profit measures across lines of
business is not available.

     Aside from the United States, no single country or geographic region
generates a significant portion of the Corporation's revenues or assets. In
addition, there are no single customer concentrations of revenue or
profitability.

     Data presented in the line of business tables prior to the caption entitled
"Financial Performance" are included in the "Business Segments" section (see
pages 3 - 18 for details).

Note 9--Guaranteed Preferred Beneficial Interest in the Corporation's Junior
Subordinated Debt

     The Corporation has sponsored nine trusts with a total aggregate issuance
of $2.790 billion at March 31, 2001 in trust preferred securities. These trust
preferred securities are tax-advantaged issues that qualify for Tier 1 capital
treatment. Distributions on these securities are included in interest expense on
long-term debt. Each of the trusts is a statutory business trust organized for
the sole purpose of issuing trust securities and investing the proceeds thereof
in junior subordinated debentures of the Corporation, the sole asset of each
trust. The preferred trust securities of each trust represent preferred
beneficial interests in the assets of the respective trusts and are subject to
mandatory redemption upon payment of the junior subordinated debentures held by
the trust. The common securities of each trust are wholly owned by the
Corporation. Each trust's ability to pay amounts due on the trust preferred
securities is solely dependent upon the Corporation making payment on the
related junior subordinated debentures. The Corporation's obligations under the
junior subordinated securities and other relevant trust agreements, in

                                      -42-

aggregate, constitute a full and unconditional guarantee by the Corporation of
each respective trust's obligations under the trust securities issued by such
trust.

Note 11--Contingent Liabilities

    The Corporation and certain of its subsidiaries have been named as
defendants in various legal proceedings, including certain class actions,
arising out of the normal course of business or operations. In certain of these
proceedings, which are based on alleged violations of consumer protection,
securities, banking, insurance and other laws, rules or principles, substantial
money damages are asserted against the Corporation and its subsidiaries. Since
the Corporation and certain of its subsidiaries, which are regulated by one or
more federal and state regulatory authorities, are the subject of numerous
examinations and reviews by such authorities, the Corporation also is and will
be, from time to time, normally engaged in various disagreements with
regulators, related primarily to its financial services businesses. The
Corporation has also received certain tax deficiency assessments. In view of the
inherent difficulty of predicting the outcome of such matters, the Corporation
cannot state what the eventual outcome of pending matters will be; however,
based on current knowledge and after consultation with counsel, Management does
not believe that liabilities arising from these matters, if any, will have a
material adverse effect on the consolidated financial position of the
Corporation.
