                         ANCHOR BANCORP WISCONSIN INC.
              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1 - PRINCIPLES OF CONSOLIDATION

The unaudited consolidated financial statements include the accounts and
results of operations of Anchor BanCorp Wisconsin Inc. (the "Corporation") and
its wholly-owned subsidiaries, AnchorBank, S.S.B. (the "Bank"), Investment
Directions, Inc. ("IDI") and Nevada Investment Directions, Inc. ("NIDI").  The
Bank's statements include its wholly-owned subsidiaries, Anchor Insurance
Services, Inc.  ("AIS"), ADPC Corporation ("ADPC"), Anchor Investment
Corporation ("AIC"),  and ADPC II LLC ("ADPC II").  All significant
intercompany balances and transactions have been eliminated.  Investments in
joint ventures and other less than 50% owned partnerships, which are not
material, are accounted for on the equity method.  Partnerships with 50%
ownership or more are consolidated, with significant intercompany accounts
eliminated.

NOTE 2 - BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements have been prepared
in accordance with generally accepted accounting principles ("GAAP") and with
the instructions to Form 10-Q and Rule 10-01 of Regulation S-X.  Accordingly,
they do not include all of the information and footnotes required by GAAP for
complete financial statements.  In the opinion of management, all adjustments
(consisting of normal recurring accruals) necessary for a fair presentation of
the consolidated financial statements have been included.

In preparing the consolidated financial statements in conformity with GAAP,
management is required to make estimates and assumptions that affect the
amounts reported in the consolidated financial statements and accompanying
notes.  Actual results could differ from those estimates.  The results of
operations and other data for the three month period ended June 30, 1997 are
not necessarily indicative of results that may be expected for any other
interim period or the entire year ending March 31, 1998.  The unaudited
consolidated financial statements presented herein should be read in
conjunction with the audited consolidated financial statements and related
notes thereto included in the Corporation's Annual Report for the year ended
March 31, 1997.

NOTE 3 - STOCKHOLDERS' EQUITY

On May 18, 1997, 1,200 shares of the management recognition plan were earned by
the recipients.  During the quarter ended June 30, 1997, options for 4,770
shares of common stock were exercised at a weighted price of $8.76 per share.
Treasury shares were issued in exchange for the options using the
last-in-first-out method. The excess of the cost of treasury shares over the
option price ($166,000) was charged to retained earnings. During the quarter
ended June 30, 1997, the Corporation repurchased  61,750 shares of common stock
on the open market for an average price of $43.81.  On May 15, 1997, the
Corporation paid out a cash dividend of $.14 per share, amounting to $637,000.

NOTE 4 - EARNINGS PER SHARE

Earnings per share for the three months ended June 30, 1997 and 1996 have been
determined by dividing net income for the respective periods by the weighted
average number of shares of common stock and common stock equivalents
outstanding.  Stock options are regarded as common stock equivalents and are
therefore considered in both primary and fully diluted earnings per share
calculations.  Common stock equivalents are computed using the treasury stock
method.

                 ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS

RESULTS OF OPERATIONS

General.  Net income for the three months ended June 30, 1997 increased
$100,000 to $4.6 million from $4.5 million for the same period in the prior
year.   The increase in net income for the three month period compared to last
year was largely due to the increase in interest income of $1.9 million and a
decrease in non-interest expense of $601,000 which were largely offset by (i)
an increase in interest expense of $2.0 million combined with (ii) a decrease
in non-interest income of  $163,000, and (iii) an increase in income taxes of
$279,000.

Net Interest Income.  Net interest income decreased $73,000 for the three
months ended June 30, 1997 compared to the same period in 1996.  The net
interest margin decreased to 3.02% from 3.24% for the three month period.  The
interest rate spread decreased to 2.85% from 3.03% for the three month period.

Interest income on loans increased $1.6 million for the three month period
ended June 30, 1997 as compared to the same period in the prior year.  This
increase was a result of the increase of $84.8 million in the average balance
of loans for the period due to the increased origination of portfolio loans.
Interest income on mortgage-related securities increased $253,000 for the same
period due primarily to the increase of $11.4 million in the average balance of
mortgage-related securities.

Interest expense on deposits increased $1.2 million for the three month period
ended June 30, 1997 as compared to the same period in 1996.  The increase was
due primarily to the increase in the average balance of deposits of $76.5
million as a result of various demand deposit and certificate promotions.  In
addition, the average rate on deposits increased from 4.67% to  4.78% during
the three months ended June 30, 1997 and 1996, respectively, primarily as a
result of the above-described deposit promotions.  Interest expense on notes
payable and other borrowings increased $752,000 during the same period.  This
was a result of an increase of $49.6 million in the average balance of
borrowings during the same period.

Non-Interest Income.   Non-interest income decreased $163,000 during the three
months ended June 30, 1997 as compared to the same period in the prior year as
a result of several factors.  The net gain on sale of loans increased $310,000,
service charges on deposits increased $73,000, and net gain on sale of
securities increased $25,000 for the same period.  These items were, however,
offset because other income decreased $575,000.  This decrease was due
primarily to decreased investment income from the Corporation.

Non-Interest Expense.  Non-interest expense decreased $600,000 during the three
month period ended June 30, 1997 as compared to the same period in 1996 as a
result of several factors.  Compensation expense decreased $689,000 due
primarily to the retirement of higher salaried individuals and the elimination
of the cost associated with the Employee Stock Ownership Plan.  Furniture and
occupancy expenses increased $316,000 largely due to increased depreciation and
other costs from additional offices.  This was combined with an increase in
data processing expense of $134,000 as well as an increase in other expenses of
$110,000, the latter of which stemmed from telephone and stationary expenses.
These increases, however, were offset by the reduction of the federal insurance
premium of $495,000, for the same period, stemming from the recapitalization of
the Savings Association Insurance Fund (SAIF) in the past fiscal year ended
March 31, 1997.

Income Taxes.  Income tax expense increased $279,000 during the three months
ended June 30, 1997 as compared to the same period in 1996.  The effective tax
rate was 38.4%  as compared to 36.5% for the same period last year.

FINANCIAL CONDITION

During the three months ended June 30, 1997, the Corporation increased its
assets $40.9 million from $1.88 billion to $1.93 billion.  The majority of this
increase was attributable to increases in loans and securities.

Investment securities (both available for sale and held to maturity) increased
$26.3 million as a result of (i) purchases of $27.1 million of U.S. Government
and agency securities and (ii) market value and other adjustments of $399,000,
which were partially offset by sales and maturities of  $1.2 million.

Mortgage-related securities (both available for sale and held to maturity)
decreased $14.1    million as a result of principal repayments and market value
adjustments.  Mortgage-related securities consisted of $197.1 million of
mortgage-backed securities and $29.2 million of mortgage-derivative securities
at June 30, 1997.

The Corporation's investments in mortgage-derivative securities are limited to
federal agency issued REMICs which represent an interest in mortgage-backed
securities.  These investments are deemed to have limited credit risk.  The
investments do have interest rate risk due to, among other things, actual
prepayments being more or less than those predicted at the time of purchase.
The Corporation invests only in short-term tranches in order to limit the
reinvestment risk associated with greater than anticipated prepayments, as well
as changes in value resulting from changes in interest rates.

Total loans (including loans held for sale) increased $29.7 million during the
three months ended June 30, 1997.  Activity for the period included (i)
originations and purchases of $193.3 million, (ii) sales of $60.6 million, and
(iii) principal repayments and other adjustments of $103.0 million.

Deposits increased $13.9 million during the three months ended June 30, 1997.
The increase was due primarily to new demand deposit products and a certificate
promotion.  Brokered deposits have been used in the past and may be used in the
future as the need for funds requires it.  Brokered deposits totalled $36.0
million at June 30, 1997 and generally mature in one year.  FHLB advances
increased $19.0 million during the three months ended June 30, 1997.  Reverse
repurchase agreements and other borrowings decreased $3.2 million during the
three months ended June 30, 1997.  Advance payments by borrowers for taxes and
insurance increased $7.0 million.

Stockholders' equity increased $2.0 million during the three months ended June
30, 1997 as a net result of (i) net income of $4.6 million, (ii) stock options
exercised of $41,000, (iii) the decrease in net unrealized loss of
available-for-sale securities of $593,000, (iv) treasury stock repurchased of
$2.7 million, (v) cash dividends of $637,000, and (vi) management recognition
plan shares earned and related tax adjustments totalling $46,000.

ASSET QUALITY

Loans are placed on non-accrual status when, in the judgment of management, the
probability of collection of interest is deemed to be insufficient to warrant
further accrual.  When a loan is placed on non-accrual status, previously
accrued but unpaid interest is deducted from interest income.  As a matter of
policy, the Corporation does not accrue interest on loans past due 90 days or
more.  

Non-performing assets (consisting of non-accrual loans, certain real
estate held for development and sale, foreclosed properties and repossessed
assets) increased to $14.6 million at June 30, 1997 from $13.8 million at March
31, 1997 and increased as a percentage of total assets to 0.76% from 0.73% at
such dates, respectively.

Non-performing assets are summarized as follows at the dates indicated:

Non-accrual loans increased $233,000 during the three months ended June 30,
1997. Non-performing real estate held for development and sale decreased
$23,000 for the three months ended June 30, 1997.  Foreclosed properties and
repossessed assets increased $654,000 during the same period.

At June 30, 1997, there was  one non-accrual loan with a carrying value of
greater than $1.0 million.  The loan, which had a total carrying value of $2.5
million, represented a 26% participation secured by a 48-unit condominium
project in Bloomington, Minnesota.  Voluntary foreclosure on this project is
presently being sought by the Bank.

Foreclosed properties and repossessed assets include two properties with a
carrying value of greater than $1.0 million.  The first property is an
apartment complex in Elm Grove, Wisconsin, which formerly secured a $2.2
million loan.  Phase I studies of the environmental impact indicated a need for
a Phase II study based on the history of the property, which the Bank is
pursuing.  The Bank believes any cleanup which may be necessary will be
partially reimbursed by the Petroleum Environmental Cleanup Fund, although
there can be no assurance in this regard.  The Bank also believes that, in the
event of any remaining environmental cleanup liability, it will pursue
reimbursement from the adjoining land owner, who is believed to have caused the
contamination.  The second is a 12-unit condominium project and associated
land in Madison, Wisconsin which formerly secured two loans totalling $1.6
million.  ADPC is presently in the process of selling individual units.

Performing troubled debt restructurings increased $2.9 million primarily due to
the addition of a hotel and office building located in Garden Grove,
California.  This loan was previously removed from foreclosed properties and
repossessed assets, in fiscal 1997, due to a repayment plan from the bankruptcy
settlement.

At June 30, 1997, assets that the Bank has classified, as "substandard", net of
reserves, consisted of $23.4 million of loans and foreclosed properties.  As of
March 31, 1997, the substandard assets amounted to $16.5 million.  The increase
was primarily due to the classification of two loans.   The first was a 93%
participation loan to the Foxhills Resort Limited Partnership located in
Mishicot, Wisconsin totalling $4.8 million.  Payments are current on the loan.
The second represented a loan for $1.7 million secured by commercial real
estate in Reno, Nevada.  The Bank is pursuing foreclosure on this loan.

The following table sets forth information relating to the Corporation's loans
which are less than 90 days delinquent at the dates indicated.

The Corporation's loan portfolio, foreclosed properties and repossessed assets
are evaluated on a continuing basis to determine the necessity for additions to
the allowances for losses and the related balance in the allowances.  These
evaluations consider several factors, including, but not limited to, general
economic conditions, loan portfolio composition, loan delinquencies, prior loss
experience, collateral value, anticipated loss of interest and management's
estimation of future





                                       13

potential losses.  The evaluation of the allowance for loan losses includes a
review of known loan problems as well as potential problems based upon
historical trends and ratios.  Foreclosed properties are recorded at the lower
of carrying value or fair value with charge-offs, if any, charged to the
allowance for loan losses prior to transfer to foreclosed property.  The fair
value is primarily based on appraisals, discounted cash flow analysis (the
majority of which are based on current occupancy and lease rates) and pending
offers.

A summary of the activity in the allowance for losses on loans follows:

Although management believes that the June 30, 1997 allowance for loan losses
is adequate based upon the current evaluation of loan delinquencies,
non-accrual loans, charge-off trends, economic conditions and other factors,
there can be no assurance that future adjustments to the allowance, which could
adversely affect the Corporation's results of operations, will not be
necessary.  Management also continues to pursue all practical and legal methods
of collection, repossession and disposal, as well as adhering to high
underwriting standards in the origination process, in order to maintain strong
asset quality.

LIQUIDITY AND CAPITAL RESOURCES

On an unconsolidated basis, the Corporation's sources of funds include
dividends from its subsidiaries, including the Bank, interest on its
investments and returns on its real estate held for sale.  The Bank's primary
sources of funds are payments on loans and mortgage-related securities,
deposits from retail and wholesale sources, advances and other borrowings.

At June 30, 1997, the Corporation had outstanding commitments to originate
loans of $70.9 million, commitments to extend funds to, or on behalf of,
customers pursuant to lines and letters of credit of $72.4 million and loans
sold with recourse to the Corporation in the event of default by the borrower
of $2.0 million.  Scheduled maturities of certificates of deposit during the
twelve months following June 30, 1997 amounted to $747.3 million and scheduled
maturities of FHLB advances during the same period totalled $295.9 million.  At
June 30, 1997, the Corporation also had $39.2 million of reverse repurchase
agreements, all of which are scheduled to mature during the twelve months
following June 30, 1997.  Management believes adequate capital and borrowings
are available from various sources to fund all commitments to the extent
required.

The Bank is required by the Office of Thrift Supervision ("OTS") to maintain
specified levels of liquid investments in qualifying types of U.S. Government
and agency securities and other investments.  This requirement, which may be
varied by the OTS, is based upon a percentage of deposits and short-term
borrowings.  The required percentage is currently 5.0%, which has been proposed
by the OTS to be reduced to 4%.  During the quarter ended June 30, 1997, the
Bank's average liquidity ratio was 10.14%.

Under federal law and regulation, the Bank is required to meet certain
tangible, core and risk-based capital requirements.  Tangible capital generally
consists of stockholders' equity minus certain intangible assets. Core capital
generally consists of tangible capital plus qualifying intangible assets.  The
risk-based capital requirements presently address credit risk related to both
recorded and off-balance sheet commitments and obligations.  As a
state-chartered savings institution, the Bank is also subject to the minimum
regulatory capital requirement of the State of Wisconsin which is 6% of total
assets.  The Bank's capital ratio for this measurement is 6.84% as of June 30,
1997.

The OTS has proposed to increase the core capital ratio from the current 3.00%
to a range of 4.00% to 5.00% for all but the most healthy financial
institutions.  The OTS has added an interest rate risk calculation such that an
institution with a measured interest rate risk exposure, as defined, greater
than specified levels must deduct an interest rate risk component when
calculating the OTS risk-based capital.  Final implementation of this rule was
pending at June 30, 1997.  Management does not believe these rules will
significantly impact the Bank's ability to meet the capital requirements.

ASSET/LIABILITY MANAGEMENT

The primary function of asset and liability management is to provide liquidity
and maintain an appropriate balance between interest-earning assets and
interest-bearing liabilities within specified maturities and/or repricing
dates.  Interest rate risk is the imbalance between interest-earning assets and
interest-bearing liabilities at a given maturity or repricing date, and is
commonly referred to as the interest rate gap (the "gap").  A positive gap
exists when there are more assets than liabilities maturing or repricing within
the same time frame.  A negative gap occurs when there are more liabilities
than assets maturing or repricing within the same time frame.  During a period
of rising interest rates, a negative gap over a particular period would tend to
adversely affect net interest income over such period, while a positive gap
over a particular period would tend to result in an increase in net interest
income over such period.

The Corporation's strategy for asset and liability management is to maintain an
interest rate gap that minimizes the impact of interest rate movements on the
net interest margin.  As part of this strategy, the Corporation sells
substantially all new originations of long-term, fixed-rate, single-family
residential mortgage loans in the secondary market, invests in adjustable-rate
or medium-term, fixed-rate, single-family residential mortgage loans, invests
in medium-term mortgage-related securities and invests in consumer loans which
generally have shorter terms to maturity and higher and/or adjustable interest
rates.

The Corporation also originates multi-family residential and commercial real
estate loans, which generally have adjustable or floating interest rates and/or
shorter terms to maturity than conventional single-family residential loans.
Long-term, fixed-rate, single-family residential mortgage loans originated for
sale in the secondary market are generally committed for sale at the time the
interest rate is locked with the borrower.  As such, these loans involve little
interest rate risk to the Corporation.

The Corporation's cumulative net gap position at June 30, 1997 for one year or
less was a negative 3.59% of total assets.  The calculation of a gap position
requires management to make a number of assumptions as to when an asset or
liability will reprice or mature.  Management believes that its assumptions
approximate actual experience and considers them reasonable, although the
actual amortization and repayment of assets and liabilities may vary
substantially.

ITEM 1           LEGAL PROCEEDINGS.

The Bank is involved in litigation relating to alleged structural deficiencies
of a property located in Vero Beach, Florida.  The Bank contracted for the
completion of this property after is was acquired by foreclosure and converted
it into a condominium complex.  In January 1993, the Bank and the Homeowners
Association, which represents the condominium owners, entered into a settlement
agreement which covers various repairs totalling $500,000 which the Corporation
accrued in September 1992 and paid in January 1993.  This also covered repairs
which are related to the post-tension cable system, an estimated amount of
which  was accrued by the Corporation in September 1993 but has not yet been
paid.  Three lawsuits have been filed against the Bank in connection with the
foregoing by various owners of condominiums in the complex and the Homeowners
Association.  During fiscal 1996, one trial involving an individual homeowner
was finished, of which the result relieved the Bank of any claim for punitive
and/or general damages, but provided the owner with recission (return of the
unit to the Bank).  The Bank is currently considering the alternatives of
appeal and/or negotiated settlement.  During fiscal 1997, the lawsuit by the
Homeowners Association was settled for $1.2 million, the amount of  which
represents a full and complete settlement of any and all alleged structural
deficiencies.  Based on the outcome of the above described cases and the
evaluation of the accruals by the Corporation to date, management does not
believe that the remaining litigation will have a material adverse effect on
the financial condition or operations of the Corporation.
