NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS



1. Basis of presentation.



The consolidated financial statements include the accounts of Great Western Bancorporation, Inc. (Great Western) and its subsidiaries. All material intercompany accounts and transactions with subsidiaries are eliminated in
consolidation.



The consolidated subsidiaries are as follows:
Great Western Bank (100.0% owned), which is chartered in Omaha, Nebraska; Great Western Bank, (96.1% owned), which is chartered in Watertown, South Dakota; Great Western Bank, (100.0% owned), which is chartered in Clive, Iowa; Great Western Service
Corporation, (100.0% owned by bank subsidiaries, excluding Great Western Bank, Omaha), a data processing organization. Great Western Bank, Omaha also owns 100.0% of GW Leasing, Inc., a leasing company.



The June 30, 2005 consolidated balance sheet has been derived from Great
Westerns audited balance sheet as of that date. The consolidated financial statements as of September 30, 2005 and for the three months ended September 30, 2005 and 2004 are unaudited but include all adjustments (consisting only of
normal recurring adjustments), which Great Western considers necessary for a fair presentation of financial position and results of its operations and its cash flows for those periods. Certain information and note disclosures normally included in
Great Westerns annual financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted. These consolidated financial statements should be read in conjunction with the consolidated
financial statements and notes thereto included in Great Westerns Form 10-K annual report for 2005 filed with the Securities and Exchange Commission. Results for the three months ended September 30, 2005 are not necessarily indicative of
the results to be expected for future periods.



2. Earnings
per common share.



Earnings per share have been computed
on the basis of weighted average number of common shares outstanding during each period presented. Dividends accumulated or declared on cumulative and noncumulative preferred stock, which totaled $38,000 and $287,000 in the three months ended
September 30, 2005 and September 30, 2004 reduced earnings available to common stockholders in the computation. Great Western has no common stock equivalents.



3. Comprehensive Income.



Comprehensive income was $6,319,000 and $12,121,000 for the three months ended September 30, 2005 and September 30, 2004. The difference between
comprehensive income and net income presented in the Condensed Consolidated Statements of Income is attributed solely to change in unrealized gains and losses on securities available for sale during the periods presented.



4. Legal Proceedings.



Great Western and its subsidiary banks are from time to time parties to
various legal actions arising in the normal course of business. Management believes there is no proceeding threatened or pending against Great Western or its subsidiaries, which, if determined adversely, would have a material adverse effect on its
financial condition or results of operations.



5. Sale of
Mortgage Servicing Rights.



On July 31, 2005, Great
Western Bank, Omaha sold $14,155,000 in mortgage servicing rights to an unrelated third party. The mortgage servicing rights sold had an original value of $39,770,000, less accumulated amortization of $22,439,000 and valuation adjustments of
$3,176,000. The unpaid principal balance of the loans related to the mortgage servicing rights sold was $1,017,422,000. The related custodial escrow balances were $7,599,000.



The mortgage servicing rights were sold for $14,040,000 less $1,104,000 in fees and selling costs. The net proceeds received
were $12,936,000 resulting in a pretax loss of $1,219,000. The final loss on the sale is contractually dependent upon the level of prepayments for a 90-day period ending October 31, 2005. Any adjustment to the loss on the sale of the mortgage
servicing rights is expected to be immaterial.

ITEM 2: MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS



GENERAL



Great Western is a multi-bank holding company organized under the laws of Iowa whose primary business is providing trust, commercial, consumer, and mortgage banking services through its Nebraska, South Dakota and Iowa
based subsidiary banks. Substantially all of Great Westerns income is generated from banking operations.



The Companys fiscal year end is June 30.



CRITICAL ACCOUNTING POLICIES



Great Westerns critical accounting policies involving the more significant judgments and assumptions used in the preparation of the consolidated
financial statements as of September 30, 2005, have remained unchanged from June 30, 2005. These policies involve the provision and allowance for loan losses, and valuation of mortgage servicing rights and intangibles. Disclosure of these
critical accounting policies is incorporated by reference under Item 7, Managements Discussion and Analysis of Financial Condition and Results of Operations in Great Westerns Annual report on Form 10-K for Great
Westerns fiscal year ended June 30, 2005.



FINANCIAL CONDITION,
LIQUIDITY AND CAPITAL RESOURCES



Average assets were
$2,713,545,000 for the three months ended September 30, 2005 compared to $2,462,285,000 for the three months ended September 30, 2004, representing a 10.20% increase. Average interest-earning assets were $2,522,918,000 for the three months
ended September 30, 2005 and $2,275,873,000 (as revised to be comparable to current year calculations) for the three months ended September 30, 2004, representing a 10.85% increase. Average assets and average interest-earning assets
increased due to internal growth and acquisitions.



Total
assets were $2,745,642,000 at September 30, 2005, an increase of $6,033,000 or 0.22% from June 30, 2005. The increase in total assets is due to a $17,008,000 increase in federal funds sold and FHLB overnight deposits and a $29,627,000
increase in securities available for sale, offset by a $22,204,000 decrease in loans, net of unearned fees and the allowance for loan losses and a $14,388,000 decrease in mortgage servicing rights.



Federal funds sold and FHLB overnight deposits were $32,616,000 and
$15,608,000 at September 30, 2005 and June 30, 2005, respectively. The increase of $17,008,000 or 108.97% was primarily due to investing excess funds generated by the decrease in loans and the increase of interest bearing deposits as the
result of advertising campaigns during the three months ended September 30, 2005.



Securities available for sale were $413,692,000 at September 30, 2005, and $384,065,000 at June 30, 2005. The increase of $29,627,000 or 7.71% was primarily due to investing excess funds generated by the
decrease in loans, the increase of interest bearing deposits as the result of advertising campaigns during the three months ended September 30, 2005, and the sale of the mortgage servicing rights. Securities available for sale with unrealized
losses were $359,305,000 at September 30, 2005 with total

##### Table of Contents

unrealized losses of $6,246,000. Securities available for sale with unrealized losses were $281,433,000 at June 30,
2005 with total unrealized losses of $4,565,000. The unrealized losses for longer than twelve continuous months were $3,561,000 at September 30, 2005 and $3,166,000 at June 30, 2005. The unrealized losses for all such securities are a
direct result of changes in interest rates. Great Western has the ability and intent to hold these securities for a period of time sufficient to allow for a recovery in fair value.



Loans, net of unearned fees and the allowance for loan losses, decreased by $22,204,000 or 1.06% due to a decline in loan
originations and the payoff of several large construction and commercial real estate loans during the three months ended September 30, 2005. Included are loans originated for resale of $9,549,000 at September 30, 2005, a decrease of
$1,485,000 when compared to $11,034,000 at June 30, 2005. The decrease in loans originated for resale is due to the timing of the sale of loans in the secondary market.



Mortgage servicing rights, net, were $776,000 at September 30, 2005, a decrease of $14,388,000 or 94.88%, from
June 30, 2005. The decrease was the result of the sale of the mortgage servicing rights as discussed in Note 5 of the financial statements.



The allowance for loan losses increased by $188,000 to $25,889,000 at September 30, 2005 from $25,701,000 at June 30, 2005. The increase
primarily resulted from the recoveries of loans charged-off in prior periods. The allowance represented 1.23% and 1.22% of loans, net of unearned fees as of September 30, 2005 and June 30, 2005.



For the three months ended September 30, 2005, Great Westerns
annualized return on average assets (ROA) was 1.11%, compared to 1.16% for the three months ended September 30, 2004. Return on average stockholders equity (ROE) for the three months ended September 30, 2005
and 2004 was 18.51% and 19.76%, respectively. The decreases in ROA and ROE are due to a 4.83% increase in net income for the three months ending September 30, 2005 compared to a 10.20% increase in average assets and a 11.92% increase in average
equity from the same period a year ago.



Cash and cash
equivalents and securities available for sale totaled $514,004,000 or 18.72% of total assets at September 30, 2005, compared to $470,851,000 or 17.19% at June 30, 2005.



At September 30, 2005, the Companys leverage ratio was 6.49%, Tier 1 risk-based capital ratio was 7.75%, and
total risk-based capital ratio was 12.25%, compared to minimum required levels of 4% for leverage and Tier 1 risk-based capital ratios and 8% for total risk-based capital ratio, subject to change at the discretion of regulatory authorities to impose
higher standards in individual cases. At September 30, 2005, the Company had net risk-weighted assets of $2,234,352,000.

The following table
presents the changes in the components of net interest income and identifies the portion of each change due to differences in the average volume of interest-earning assets and interest-bearing liabilities and the portion of each change due to the
average rate on those assets and liabilities. The changes in interest due to both volume and rate changes in the table have been allocated to volume or rate change in proportion to the absolute dollar amounts of the change in each. The table is
presented on a tax-equivalent basis, assuming a 35% tax rate.

Provision for Loan Losses



The provision for
loan losses for the three months ended September 30, 2005 was $1,255,000, compared to $856,000 for the three months ended September 30, 2004. The increase was due to an increase in estimated loan losses for the current period.



Noninterest Income



Noninterest income for the three months ended September 30, 2005 was
$7,180,000, a decrease of $345,000 or 4.59% over the same period last fiscal year. The decrease primarily resulted from the $1,219,000 loss on the sale of mortgage servicing rights and the $764,000 decrease in loan servicing fees, offset by the
increase of $923,000 in service charges and other fees and the $585,000 increase in other noninterest income.



The loss on the sale of mortgage servicing rights and the decrease of the loan servicing fees is a result of the sale of the mortgage servicing rights as
discussed in Note 5 of the financial statements.



Service
charges and other fees increased to $5,275,000 during the three months ended September 30, 2005 from $4,352,000 during the three months ended September 30, 2004. The $923,000 or 21.21% increase is a result of the increase in overdraft and
non-sufficient fund charges. The increase in overdraft and non-sufficient fund charges is primarily due to the increased number of demand deposit accounts and the increased promotion of certain demand deposit products since September 30, 2004.



Other noninterest income increased to $1,266,000 during the
three months ended September 30, 2005 from $681,000 during the three months ended September 30, 2004. The increase of $585,000 or 85.90% is primarily the result of a $334,000 increase in the gain on sale of other real estate owned and a
$75,000 increase in the insurance commissions.



Noninterest Expense



Noninterest expense for
the three months ended September 30, 2005 was $18,844,000, an increase of $1,158,000 or 6.55% over the same period last fiscal year. The increase resulted primarily from a $786,000 increase in salaries and employee benefits expense, a $307,000
increase in occupancy expense, a $130,000 increase in data processing expense and a $145,000 increase in advertising expense. The increase in noninterest expense was partially offset by the decrease of $433,000 of the amortization and valuation
adjustments of mortgage servicing rights.



Salaries and
employee benefits expense increased by $786,000 or 8.34%, to $10,205,000 for the three months ended September 30, 2005 from $9,419,000 for the three months ended September 30, 2004. Contributing to the increase in salaries and employee
benefit expense was an increase in full time employees.The total number of full time

employees increased as a result of acquisitions and de novo branch expansion since September 30, 2004.The
approximate number of full time employees at September 30, 2005 was 859 compared to 781 at September 30, 2004, an increase of 78 full time employees or 9.99%.



Occupancy expense increased by $307,000 or 25.99%, to $1,488,000 for the three months ended September 30, 2005 from
$1,181,000 for the three months ended September 30, 2004. The increase is a result of the increased number of banking locations. The number of banking locations was 85 at September 30, 2005 and 72 at September 30, 2004, an increase of
13 locations.



Data processing expense increased by $130,000 or
12.75% to $1,150,000 for the three months ended September 30, 2005 from $1,020,000 for the three months ended September 30, 2004. The increase in data processing costs was a result of the increased number of banking locations and the
dollar volume of loan and deposit accounts maintained on Great Westerns core banking applications.



Advertising expense increased by $145,000 or 13.86% to $1,191,000 for the three months ended September 30, 2005 from $1,046,000 for the three months
ended September 30, 2004. The increase is due to certificate of deposit advertising campaigns conducted during the three months ended September 30, 2005.



The $433,000 decrease in the amortization and valuation adjustments of mortgage servicing rights is a result of the sale of
the mortgage servicing rights as discussed in Note 5 of the financial statements.



Income Taxes



Income taxes for the three months ended September 30, 2005 and September 30, 2004 were $4,445,000 and $3,977,000. The increase is due to a 7.34%
or $829,000 increase in pretax income and an increase in the effective tax rate. The effective tax rate for the three months ended September 30, 2005 and September 30, 2004, were 36.66% and 35.21%, respectively. The effective income tax
rate is higher for the 2005 period compared to the 2004 period due to a change in permanent taxable differences.



ITEM 3: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK



Asset/liability management refers to managements efforts to minimize fluctuations in net interest income caused by interest rate changes. This is
accomplished by managing the repricing of interest rate sensitive interest earning assets and interest bearing liabilities. Controlling the maturity or repricing of an institutions liabilities and assets in order to minimize interest rate risk
is commonly referred to as gap management. Close matching of the repricing of assets and liabilities will normally result in little change in net interest income when interest rates change. A mismatched gap position will normally result in changes
in net interest income as interest rates change.



Management
regularly monitors the interest sensitivity position and considers this position in its decisions with regard to the Companys interest rates and maturities for interest earning assets acquired and interest bearing liabilities accepted.



There has not been a material change in the interest rate
sensitivity of the Company during the three months ended September 30, 2005.



ITEM 4: CONTROLS AND PROCEDURES



Based upon their evaluation of the effectiveness of Great Westerns disclosure controls and procedures (as defined in Exchange Act rules 13a-15(e) and 15d-15(e)), Deryl F. Hamann, Chairman of the Board, Chief Executive Officer, and
James R. Clark, Chief Financial Officer, believe that Great Westerns disclosure controls and procedures were effective as of September 30, 2005.



There were no significant changes in Great Westerns internal controls or in other factors that could significantly affect these controls subsequent
to September 30, 2005 through the date of this quarterly report on Form 10-Q/A, including any corrective actions with regard to significant deficiencies and material weaknesses.
