Basis of Presentation	'
	Note 1 – Basis of Presentation
	The unaudited consolidated financial statements include the accounts and results of operations of Anchor BanCorp Wisconsin Inc. (the “Corporation” or the “Company”) and its wholly-owned subsidiaries, AnchorBank, fsb (the “Bank”) and Investment Directions, Inc. (“IDI”). The Bank has one subsidiary at September 30, 2013: ADPC Corporation. Significant inter-company balances and transactions have been eliminated.
	The accompanying unaudited interim consolidated financial statements have been prepared in accordance with U.S. 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 (including normal recurring accruals) necessary for a fair presentation of the unaudited interim consolidated financial statements have been included.
	In preparing the unaudited consolidated financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the valuation of foreclosed real estate, the net carrying value of mortgage servicing rights and deferred tax assets, and the fair value of investment securities, interest rate lock commitments, forward contracts to sell mortgage loans, and loans held for sale. The results of operations and other data for the three- and six-month periods ended September 30, 2013 are not necessarily indicative of results that may be expected for the fiscal year ending March 31, 2014. We have evaluated all subsequent events through the date of this filing. The interim 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 on Form 10-K for the fiscal year ended March 31, 2013.
	Certain prior period amounts have been reclassified to conform to the current period presentations with no impact on net income (loss) or total stockholders’ equity (deficit).

	Note 2 – Significant Transactions, Significant Risks and Uncertainties
	Bankruptcy Proceedings and Emergence from Chapter 11
	Background
	Headquartered in Madison, Wisconsin, the Company is a savings and loan holding company that operates primarily through AnchorBank, its wholly owned banking subsidiary. The Bank is a $2.2 billion bank and Wisconsin’s largest thrift. Anchor Bank offers personal and business banking services to more than 110,000 households and businesses.
	As a result of the economic downturn, significant operating losses beginning in fiscal 2009, significant levels of criticized assets and low levels of capital raised substantial doubt about the Corporation’s ability to continue as a going concern. The Company and the Bank were operating under Orders to Cease and Desist issued by the Office of Thrift Supervision in 2009, and the Corporation had outstanding $116.3 million owed to various lenders led by U. S Bank under a short term line of credit (the “Credit Agreement”) which it was unable to repay. Additionally, the Company obtained funds in 2009 by issuing senior preferred shares as part of the Troubled Asset Relief Program (“TARP”). These funds were then distributed downstream to Anchor Bank. The Corporation continued to negotiate and obtain amendments to the Credit Agreement and diligent efforts were made to seek qualified sources of outside capital.
	Bankruptcy Proceedings
	On August 12, 2013, the Company filed a voluntary petition for relief (the “Chapter 11 Case”) under the provisions of chapter 11 of title 11 of the United States Code, 11 U.S.C. §§ 101, et seq. (the “Bankruptcy Code”), Case No. 13-14003-rdm, in the United States Bankruptcy Court for the Western District of Wisconsin (the “Bankruptcy Court”) to implement the Plan of Reorganization in order to facilitate the restructuring of the Company and the recapitalization of the Bank. Prior to the petition date, U.S. Bank National Association and Bank of America, N.A., as senior secured creditors of the Company (the “Lenders”), and the Treasury, as sole preferred stockholder of the Company, voted to accept the Plan of Reorganization.
	On August 30, 2013, the Bankruptcy Court entered the Confirmation Order, by which it confirmed the Plan of Reorganization. On September 27, 2013 (the “Effective Date”), the Plan of Reorganization became effective in accordance with its terms. During the period of bankruptcy, $1.9 million of expenses, primarily comprised of professional fees, were incurred and expensed as reorganization costs in the current period.
	Emergence Accounting
	Upon emergence, the Company determined it did not meet the requirements to apply fresh start accounting under applicable accounting standards because it did not meet the solvency criteria of ASC 852-10-45-19. The reorganization value was greater than the post-petition liabilities and allowed claims and, therefore, indicative of not meeting the test to require fresh start accounting under ASC 852. Accordingly, a new reporting entity was not created for accounting purposes and there were no fair value adjustments. At the time of filing for chapter 11, the Company identified liabilities subject to compromise of $188.3 million, which included the outstanding Credit Agreement of approximately $116.3 million, interest and fees due under the Credit Agreement of $67.2 million and $4.8 million in other liabilities.
	Below is a summary of the significant transactions affecting the Company as a result of the effectiveness of the Plan of Reorganization.
	Delaware Conversion
	Pursuant to the Plan of Reorganization, on September 25, 2013, we (i) converted from a Wisconsin corporation to a Delaware corporation in accordance with Section 265 of the Delaware General Corporation Law and (ii) filed a Certificate of Incorporation with the Secretary of State of the State of Delaware (the “Amended Charter”), to, among other things, declassify our Board, increase the number of authorized shares of our common stock and adopt certain restrictions on acquisitions and dispositions of our securities. The Amended Charter provides for (a) 2,000,000,000 shares of authorized common stock, par value $0.01 per share (the “Common Stock”), and (b) 1,000,000 shares of authorized preferred stock, par value $0.01 per share. A reverse stock split was effected and a subsequent amendment to the corporate charter was filed on October 2, 2013 providing for 11,900,000 shares of authorized common stock, par value $0.01 per share and 100,000 shares of authorized preferred stock, par value $0.01. There are 9,050,000 shares of Common Stock outstanding as of September 30, 2013.
	Private Placements
	In connection with the Plan of Reorganization, we entered into stock purchase agreements with certain institutional and other private investors and directors and officers of the Company (the “Investors”) for the purchase and sale of 1,750,000,000 (adjusted on October 2, 2013 as a result of a reverse stock split to 8,750,000 shares) shares of our Common Stock at a purchase price of $0.10 per share.
	Pursuant to the stock purchase agreements, we issued and sold the Common Stock to (i) certain Investors such that, after giving effect to the transactions contemplated in the Plan of Reorganization, each such Investor owns up to 9.9% of the Common Stock pursuant to the Private Placements and the Treasury Issuance (as defined below), for an aggregate purchase price of $87.8 million, (ii) certain other Investors such that, after giving effect to the transactions contemplated in the Plan of Reorganization, each such Investor owns up to 4.9% of the Authorized Common Stock pursuant to the Private Placements and the Treasury Issuance, for an aggregate purchase price of $83.7 million, and (iii) certain directors and officers of the Company for an aggregate purchase price of $3.5 million. We received gross proceeds of $175.0 million as a result of the Private Placements and incurred $14.4 million of capital raise costs all of which have been recorded in the Statement of Changes in Stockholders’ Equity.
	TARP Exchange
	On January 30, 2009, pursuant to the Treasury’s Capital Purchase Program, we issued and sold to the Treasury 110,000 shares of Fixed Rate Cumulative Perpetual Preferred Stock, Series B of the Company with an aggregate liquidation preference of $110.0 million (the “TARP Preferred Stock”). In addition, we issued to the Treasury a warrant (the “TARP Warrant”) to purchase up to 7,399,103 shares of our common stock, par value $0.10 per share (the “Legacy Common Stock”), at an initial per share exercise price of $2.23. Pursuant to the Plan of Reorganization, we, on the Effective Date and immediately following the consummation of the Private Placements, (i) exchanged the TARP Preferred Stock for 60.0 million shares (adjusted to 300,000 shares as a result of the reverse stock split) of Common Stock (the “Treasury Issuance”) and (ii) cancelled the TARP Warrant in its entirety (collectively, the “TARP Exchange”). The difference between the Common Stock issued and the Preferred Stock redeemed of $104.0 million was recorded as an increase directly to retained earnings. The $104.0 million represents a return from the Preferred stockholder thereby increasing the amount available to common stockholders for purposes of earnings per share.
	Following the effectiveness of the Plan of Reorganization, the Treasury sold to certain institutional investors (the “Secondary Investors”) all of the shares of Common Stock delivered to the Treasury in connection with the Treasury Issuance at a purchase price equal to $0.10 per share (the “Secondary Treasury Sales”) under the securities purchase agreements, dated as of September 19, 2013, among the Treasury, the Secondary Investor and (with respect to certain provisions) the Company. In connection with the Secondary Treasury Sales, we entered into secondary sale purchaser agreements with the Secondary Investors pursuant to which we made certain representations and warranties to the Investor and provided rights to the Secondary Investors similar to the rights provided to Investors under the Stock Purchase Agreements. In connection with the Secondary Treasury Sales, the Treasury received gross proceeds of $6,000,000 and ceased to be our stockholder.
	Cancellation of Legacy Common Stock
	As of July 31, 2013, we had 21,247,225 shares of Legacy Common Stock issued and outstanding. On the Effective Date, immediately following the consummation of the TARP Exchange, all shares of the outstanding Legacy Common Stock including those shares held as treasury stock and in any stock incentive plans were cancelled for no consideration pursuant to the Plan of Reorganization. In connection with the cancellation of the Legacy Common Stock pursuant to the Plan of Reorganization, the Rights Agreement, dated as of November 5, 2010, by and between the Company and American Stock Transfer & Trust Company, LLC was terminated on the Effective Date in accordance with its terms.
	Senior Debt Settlement
	We were a party to the Amended and Restated Credit Agreement, dated as of June 9, 2008, among the Company, the lenders from time to time a party thereto (the “Lenders”), and U.S. Bank National Association, as administrative agent for the Lenders. As of June 30, 2013, the aggregate amount of obligations under the Credit Agreement was approximately $183.0 million (including with respect to unpaid principal balance, accrued but unpaid interest thereon and all administrative and other fees or penalties). On the Effective Date, pursuant to the Plan of Reorganization, we satisfied all of our obligations under the Credit Agreement by a cash payment to the Lenders of $49.0 million (plus expense reimbursement as contemplated by the Credit Agreement). As a result of the transaction, we recognized a gain on extinguishment of debt of $134.5 million.
	Regulatory Agreements
	The Bank’s primary regulator is the Office of the Comptroller of the Currency (“OCC”). The Federal Reserve is the primary regulator of the Corporation. On September 26, 2009, the Corporation and the Bank each consented to the issuance of an Order to Cease and Desist (the “Corporation Order” and the “Bank Order,” respectively, and together, the “Orders”).
	The Corporation Order requires the Corporation to notify, and in certain cases to obtain the permission of, the Federal Reserve prior to: (i) declaring, making or paying any dividends or other capital distributions on its capital stock, including the repurchase or redemption of its capital stock; (ii) incurring, issuing, renewing or rolling over any debt, increasing any current lines of credit or guaranteeing the debt of any entity; (iii) making certain changes to its directors or senior executive officers; (iv) entering into, renewing, extending or revising any contractual arrangement related to compensation or benefits with any of its directors or senior executive officers; and (v) making any golden parachute payments or prohibited indemnification payments. In July 2010, the Corporation developed and submitted to the Office of Thrift Supervision, the Corporation’s primary regulator at the time until it was disbanded in 2011 and the Federal Reserve assumed the role of primary regulator, a three-year cash flow plan, which must be reviewed at least quarterly by the Corporation’s management and board of directors for material deviations between cash flow plan projections and actual results (the “Variance Analysis Report”). Within 45 days following the end of each quarter, the Corporation is required to provide and has been providing the Federal Reserve its Variance Analysis Report for that quarter.
	The Bank Order requires the Bank to notify, or in certain cases obtain the permission of, the OCC prior to (i) increasing its total assets in any quarter in excess of an amount equal to net interest credited on deposit liabilities during the quarter; (ii) accepting, rolling over or renewing any brokered deposits; (iii) making certain changes to its directors or senior executive officers; (iv) entering into, renewing, extending or revising any contractual arrangement related to compensation or benefits with any of its directors or senior executive officers; (v) making any golden parachute or prohibited indemnification payments; (vi) paying dividends or making other capital distributions on its capital stock; (vii) entering into certain transactions with affiliates; and (viii) entering into third-party contracts outside the normal course of business. The Bank also developed and submitted within the prescribed time periods, a written capital restoration plan, a problem asset plan, a revised business plan, and an implementation plan resulting from a review of commercial lending practices. The Orders also require the Bank to regularly review its current liquidity management policy and the adequacy of its allowance for loan and lease losses.
	The Bank is also subject to a capital restoration plan including a Prompt Corrective Action Directive (“PCA”). Under the PCA, the Bank must obtain prior written approval before entering into any contract or lease for the purchase or sale of real estate or of any interest therein, except for contracts entered into in the ordinary course of business for the purchase or sale of other real estate owned due to foreclosure (“OREO”) where the contract does not exceed $3.5 million and the sales price of the OREO does not fall below 85% of the net carrying value of the OREO.
	The Orders also stipulated that, as of September 30, 2009, the Bank was required to meet and maintain both a core capital ratio equal to or greater than 7% and a total risk-based capital ratio equal to or greater than 11%. Further, as of December 31, 2009, the Orders required the Bank to meet and maintain both a core capital ratio equal to or greater than 8% and a total risk-based capital ratio equal to or greater than 12%.
	As disclosed above and in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Form 10-Q, on September 27, 2013, pursuant to a pre-packaged plan of reorganization (the “Plan of Reorganization”) to facilitate the restructuring of the Corporation and the recapitalization of the Bank, the Corporation completed a capital raise and received gross proceeds of $175.0 million. See “Executive Overview.”
	At September 30, 2013, the Bank had a tier 1 leverage (core) ratio of 9.06% and a total risk-based capital ratio of 16.30%, each meeting the required capital ratios set forth above. As a result of the Plan of Reorganization and the recapitalization of the Bank, the Bank is in compliance with the tier 1 (core) leverage and total risk-based capital ratios as required by the Bank Order. All customer deposits remain fully insured to the highest limits set by the FDIC.
	Going Concern
	Our March 31, 2013 audit opinion contained a going concern matter due to the previous default on our credit agreement and inability to meet minimum capital requirements. During the most recent quarters, the following events and transactions occurred to address those concerns: On August 12, 2013, the Company filed a voluntary petition for relief under the provisions of Chapter 11 of Title 11 of the Bankruptcy Code in the United States Bankruptcy Court for the Western District of Wisconsin to implement a pre-packaged plan of reorganization (the “Plan of Reorganization”) in order to facilitate the restructuring of the Company and the recapitalization of the Bank.
	On August 30, 2013, the Bankruptcy Court entered the Confirmation Order, by which it confirmed the Plan of Reorganization. As disclosed above and in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Form 10-Q, on September 27, 2013, pursuant to the Plan of Reorganization, the Corporation completed a capital raise and received gross proceeds of $175.0 million. See “Executive Overview.” As a result of the Plan of Reorganization and the recapitalization of the Bank, the Bank is in compliance with the tier 1 (core) leverage and total risk-based capital ratios as required by the Bank Order.
	On September 27, 2013, pursuant to the Plan of Reorganization, the Corporation (i) exchanged the TARP Preferred Stock for 60.0 million shares of common stock (adjusted to 300,000 shares as a result of the reverse stock split) and (ii) cancelled the TARP Warrant in its entirety. Further, the Corporation has settled its obligations under the Amended and Restated Credit Agreement (“Credit Agreement”) among the Corporation, the lenders from time to time a party thereto, and U.S. Bank National Association, as administrative agent for such lenders.
	Credit Risks
	Non-performing assets totaled $162.9 million at September 30, 2013, or 7.43% of total assets, which decreased the Corporation’s interest income. The Corporation’s results of operations will continue to be impacted by the level of non-performing assets, and the Corporation expects continued downward pressure on interest income in the future. As reported in the accompanying unaudited consolidated financial statements, the Corporation has net income of $113.3 million and $107.9 million for the three and six month periods ended September 30, 2013, respectively, and net losses of $8.6 million and $8.5 million for the three and six months ended September 30, 2012, respectively. Stockholders’ equity increased from a deficit of $59.9 million or (2.53)% of total assets at March 31, 2013 to $201.0 million or 9.18% of total assets at September 30, 2013.

	ASU 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. ASU 2013-11 requires that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit shall be presented in the financial statements as a liability and shall not be combined with deferred tax assets. The assessment of whether a deferred tax asset is available is based on the unrecognized tax benefit and deferred tax asset that exist at the reporting date and shall be made presuming disallowance of the tax position at the reporting date. The amendments do not require new recurring disclosures.
	The amendments are an improvement to current U.S. GAAP because they are expected to reduce diversity in practice by providing guidance on the presentation of unrecognized tax benefits and will better reflect the manner in which an entity would settle at the reporting date any additional income taxes that would result from the disallowance of a tax position when net operating loss carryforwards, similar tax losses, or tax credit carryforwards exist. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The Company already complies with this presentation requirement.
	ASU No. 2013-02, “Comprehensive Income (Topic 220) – Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.” ASU 2013-02 requires entities to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under U.S. generally accepted accounting principles (GAAP) to be reclassified in its entirety to net income. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under U.S. GAAP that provide additional detail about those amounts. This would be the case when a portion of the amount reclassified out of accumulated other comprehensive income is reclassified to a balance sheet account instead of directly to income or expense in the same reporting period.
	The amendments do not change the current requirements for reporting net income or other comprehensive income in financial statements. However, the amendments require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. The Corporation adopted ASU 2013-02 as of March 31, 2013 and is presented in the Consolidated Statements of Comprehensive Income (Loss).

	Independent pricing services are used to value all investment securities with one pricing service valuing all securities except the non-agency CMOs. A specialized pricing service is used for valuation of the non-agency CMO portfolio.
	To estimate the fair value of non-agency CMOs, the pricing service valuation model discounted estimated expected cash flows after credit losses at rates ranging from 4% to 7%. The rates utilized are based on the risk-free rate equivalent to the remaining average life of the security, plus a spread for normal liquidity and a spread to reflect the uncertainty of the cash flow estimates. The pricing service benchmarks its fair value results to other pricing services and monitors the market for actual trades. The cash flow model includes these inputs in its derivation of the discount rates used to estimate fair value. There are no payments in kind allowed on these non-agency CMOs.
	The table below presents the fair value and gross unrealized losses of all securities in a loss position, aggregated by investment category and length of time that individual investments have been in a continuous unrealized loss position at September 30, 2013 and March 31, 2013.

	Other-Than-Temporary Impairment
	The number of individual securities in the tables above total 29 at September 30, 2013 and 15 at March 31, 2013. Although these securities have declined in value, the unrealized losses are considered temporary. Management evaluates securities for other-than-temporary impairment on a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. In estimating other-than-temporary impairment losses on investment securities, management considers many factors which include: (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent and ability of the Corporation to retain its investment for a period of time sufficient to allow for any anticipated recovery in fair value.
	To determine if an other-than-temporary impairment exists on a debt security with an unrealized loss, the Corporation first determines if (a) it intends to sell the security or (b) it is more likely than not that it will be required to sell the security before its anticipated recovery. If either of the conditions is met, an other-than-temporary impairment loss is recognized in earnings equal to the difference between the security’s fair value and its amortized cost basis. If neither condition is met, the Corporation determines (a) the amount of the impairment related to credit loss and (b) the amount of the impairment due to all other factors. The difference between the present values of the cash flows expected to be collected, discounted at the purchase yield or current accounting yield of the security, and the amortized cost basis is the credit loss. The credit loss is the portion of the impairment that is deemed other-than-temporary and recognized in earnings and is a reduction in the cost basis of the security. The portion of impairment related to all other factors is deemed temporary and included in other comprehensive income (loss).
	An independent pricing service is utilized to run a discounted cash flow model in the calculation of other-than-temporary impairment losses on non-agency CMOs. This model determines the portion of the impairment that is other-than-temporary due to credit losses, and the portion that is temporary due to all other factors.
	The significant inputs used for calculating the credit loss portion of securities with other-than-temporary impairment (“OTTI”) include prepayment assumptions, loss severities, original FICO scores, historical rates of delinquency, percentage of loans with limited underwriting, historical rates of default, original loan-to-value ratio, aggregate property location by metropolitan statistical area, original credit support, current credit support, and weighted-average maturity.
	The discount rates used to establish the net present value of expected cash flows for purposes of determining OTTI ranged from 4% to 7%. These rates equate to the effective yield implicit in the security at the date of acquisition of the bonds for which OTTI has not been previously incurred. For bonds with previously recorded OTTI, the discount rate used equates to the accounting yield on the security as of the valuation date.
	Default rates were calculated separately for each category of underlying borrower based on delinquency status (i.e. current, 30 to 59 days delinquent, 60 to 89 days delinquent, 90+ days delinquent, and foreclosure balances) of the underlying loans as of September 1, 2013. This data is entered into a loss migration model to calculate projected default rates, which are benchmarked against results that have recently been experienced by other major servicers of non-agency CMOs with similar attributes. The month one to month 24 constant default rate in the model ranged from 5.23% to 10.92%.
	At September 30, 2013, six non-agency CMOs with a fair value of $6.5 million and an adjusted cost basis of $6.7 million were other-than-temporarily impaired. At March 31, 2013, six non-agency CMOs with a fair value of $6.9 million and an adjusted cost basis of $7.3 million were other-than-temporarily impaired. Unrealized other-than-temporary impairment due to credit losses of zero was included in earnings for the three and six months ended September 30, 2013 and $146,000 and $210,000 for the three and six months ended September 30, 2012, respectively. For the three months ended September 30, 2013 and 2012, realized losses of $91,000 and $172,000, respectively, and $158,000 and $310,000 for the six month periods, respectively, related to credit issues (i.e. – principal reduced without a receipt of cash) were incurred that were previously recognized in earnings as unrealized other-than-temporary impairment.
	Unrealized losses on U.S. government sponsored and federal agency obligations, corporate stocks and bonds and Ginnie Mae (“GNMA”) mortgage-backed securities as of September 30, 2013 and 2012 due to changes in interest rates and other non-credit related factors totaled $5.9 million and $106,000, respectively. The Corporation has analyzed these securities for evidence of other-than-temporary impairment and concluded that no OTTI exists and that the unrealized losses are properly classified in accumulated other comprehensive income.
	The following table is a roll forward of the amount of other-than-temporary impairment related to credit losses that have been recognized in earnings for which a portion of impairment was deemed temporary and recognized in other comprehensive income for the three and six months ended September 30, 2013 and 2012:

	Residential Loans
	At September 30, 2013, $535.9 million, or 32.1%, of the total loans unpaid principal balance receivable consisted of residential loans, substantially all of which were 1 to 4 family dwellings. Residential loans consist of both adjustable and fixed-rate loans. The adjustable-rate loans currently in the portfolio have up to 30-year maturities and terms which permit the Corporation to annually increase or decrease the rate on the loans, based on a designated index. These rate changes are generally subject to a limit of 2% per adjustment and an aggregate 6% adjustment over the life of the loan. These loans are documented according to standard industry practices. The Corporation makes a limited number of interest-only loans which tend to have a shorter term to maturity and does not originate negative amortization and option payment adjustable rate mortgages.
	Adjustable-rate loans decrease the risks associated with changes in interest rates but involve other risks, primarily because as interest rates rise, the payment by the borrower rises to the extent permitted by the terms of the loan, thereby increasing the potential for default. At the same time, the marketability of the underlying property may be adversely affected by higher interest rates. The Corporation believes that these risks, which have not had a material adverse effect to date, generally are less than the risks associated with holding fixed-rate loans in an increasing interest rate environment. Also, as interest rates decline, borrowers may refinance their mortgages into fixed-rate loans thereby prepaying the balance of the loan prior to maturity. At September 30, 2013, approximately $329.9 million, or 61.6%, of the held for investment residential loans unpaid principal balance consisted of loans with adjustable interest rates.
	The Corporation continues to originate long-term, fixed-rate conventional mortgage loans. Current production of these loans with terms of 15 years or more are generally sold to Fannie Mae, Freddie Mac and other institutional investors, while a portion of loan production is retained in the held for investment portfolio. In order to provide a full range of products to its customers, the Corporation also participates in the loan origination programs of Wisconsin Housing and Economic Development Authority (“WHEDA”), Wisconsin Department of Veterans Affairs (“WDVA”) and the Federal Housing Administration (“FHA”). The Corporation retains the right to service substantially all loans that it sells.
	At September 30, 2013, approximately $206.0 million, or 38.4%, of the held for investment residential loans unpaid principal balance consisted of loans with fixed rates of interest. Although these loans generally provide for repayments of principal over a fixed period of 10 to 30 years, because of prepayments and due-on-sale clauses, such loans generally remain outstanding for a substantially shorter period of time.
	Commercial and Industrial Loans
	The Corporation originates loans for commercial, corporate and business purposes, including issuing letters of credit. At September 30, 2013, the unpaid principal balance receivable of commercial and industrial loans amounted to $30.3 million, or 1.8%, of the total loans unpaid principal balance receivable. The commercial and industrial loan portfolio is comprised of loans for a variety of business purposes and the loans generally are secured by equipment, machinery and other corporate assets. These loans generally have terms of five years or less and interest rates that float in accordance with a designated published index. Substantially all such loans are secured and backed by the personal guarantees of the owners of the business.
	Commercial Real Estate Loans
	The Corporation originates commercial real estate loans which include land and construction, multi-family, retail/office and other commercial real estate. Such loans generally have adjustable rates and shorter terms than single-family residential loans, thus increasing the earnings sensitivity of the loan portfolio to changes in interest rates, as well as providing higher fees and rates than residential loans. At September 30, 2013, $725.0 million of loans unpaid principal balance receivable were secured by commercial real estate, which represented 43.4% of the total loans unpaid principal balance. The origination of such loans is generally limited to the Corporation’s primary market area.
	Commercial real estate loans are primarily secured by apartment buildings, office and industrial buildings, land, warehouses, small retail shopping centers and various special purpose properties, including community-based residential facilities and senior housing. Although terms vary, commercial real estate loans generally have fixed interest rates, amortization periods of 15 to 25 years, as well as balloon payments of two to seven years, and terms which provide that the interest rates thereon may be adjusted annually based on a designated index.
	Consumer Loans
	The Corporation offers consumer loans in order to provide a wider range of financial services to its customers. At September 30, 2013, $378.2 million, or 22.7%, of the total loans unpaid principal balance receivable consisted of consumer loans. Consumer loans which includes second mortgages typically have higher interest rates than mortgage loans but generally involve more risk than mortgage loans because of the type and nature of the collateral and, in certain cases, the absence of collateral.
	The residential-other portfolio included in the other consumer loan category consists primarily of Express refinance first mortgage loans, second mortgage and home equity loans. Express refinance loans are available for owner occupied one- to two-family residential properties, with loan amounts up to $200,000, a fixed interest rate, up to 15 year amortization, low fees and rapid closing timeframes. The primary home equity loan product has an adjustable rate that is linked to the prime interest rate and is secured by a mortgage, either a primary or a junior lien, on the borrower’s residence. New home equity lines do not exceed 90% of appraised value of the property at the loan origination date. A fixed-rate home equity second mortgage term product is also offered.
	Approximately $138.1 million, or 8.3%, of the total loans unpaid principal balance receivable at September 30, 2013 consisted of education loans. These loans are generally made for a maximum of $3,500 per year for undergraduate studies and $8,500 per year for graduate studies and are placed in repayment status on an installment basis within nine months following graduation. Education loans generally have interest rates that adjust annually in accordance with a designated index. Both the principal amount of an education loan and interest thereon are generally guaranteed by the Great Lakes Higher Education Corporation up to 97% of the balance of the loan, which typically obtains reinsurance of its obligations from the U.S. Department of Education. The origination of student loans was discontinued beginning October 1, 2010 following the March 2010 law ending loan guarantees provided by the U. S. Department of Education. Although direct student loans, without a government guarantee, may be originated, risk-adjusted returns for these loans continue to be unattractive. Education loans may be sold to the U.S. Department of Education or to other investors. No education loans were sold during the three and six months ended September 30, 2013 and 2012.
	The other consumer loan portfolio also includes vehicle loans and other secured and unsecured loans made for a variety of consumer purposes. These include credit extended through credit cards issued by a third party, ELAN Financial Services (ELAN), pursuant to an agency arrangement under which the Corporation participates in outstanding balances, currently at 25% to 28%. The Corporation also shares 33% to 37% of annual fees, and 30% of late payment, over limit and cash advance fees, as well as 25% to 30% of interchange income from the underlying portfolio.
	Allowances for Loan Losses
	The allowance for loan losses consists of general, substandard and specific components even though the entire allowance is available to cover losses on any loan. The specific allowance component relates to impaired loans (i.e. – non-accrual) and loans reported as troubled debt restructurings. For such loans, an allowance is established when the discounted cash flows (or collateral value if repayment relies solely on the operation or sale of the collateral) of the impaired loan are lower than the carrying value of that loan. The substandard loan component is primarily associated with loans rated in this category but not in non-accrual status. These two components make up the general reserve. The general allowance component covers pass, watch and special mention rated loans and is based on historical loss experience adjusted for various qualitative and quantitative factors. Loans graded substandard and below are individually examined to determine the appropriate loan loss reserve. In addition, a reserve for unfunded commitments, letters of credit and repurchase of sold loans is maintained and classified in other liabilities.
	For the quarter ended June 30, 2013, the Bank modified its general allowance methodology to increase the historical loss period from a six to seven quarter historical look-back period and further increased the loss period to an eight quarter look-back in quarters beginning with September 2013. The modification was done to reflect a more stable economic environment and to capture additional loss statistics considered reflective of the current portfolio. In addition, as the Bank begins to increase its new loan originations, a new loan risk factor was added to capture the unique risk factor adjustments needed for loans originated after September 2012, reflecting a different risk level as compared to the existing legacy portfolio. The impact to the allowance for loan losses at September 30, 2013 after implementing the above modifications was a reduction of the required reserve of $2.0 million as compared to the previous methodology. See the Company’s annual report on Form 10-K for the fiscal year ended March 31, 2013 for a full description of the allowance methodology.

The provisions for loan losses is recorded as a deduction from net interest income on the Consolidated Statements of Operations and was zero and $275,000 for the three and six months ended September 30, 2013, respectively, compared to $5.0 million and $2.2 million for the same periods in 2012, respectively.
A provision for unfunded loan commitments is recorded and includes provisions for unfunded commitments to lend, commercial letters of credit and repurchased loans from previously sold loans and is included in non-interest expense on the Consolidated Statements of Operations. The provision for unfunded commitments for the three and six months ended September 30, 2013 was $1.0 million and $2.7 million, respectively, and $0.3 million and $1.4 million for the same periods ending September 30, 2012, respectively.
At September 30, 2013, $134.6 million of unpaid principal balance of loans were identified as impaired which includes performing troubled debt restructurings. At March 31, 2013, impaired loans were $160.4 million. A loan is identified as impaired when, based on current information and events, it is probable that all amounts due according to the contractual terms of the loan agreement may not be collected and thus are placed on non-accrual status. Interest income on certain impaired loans is recognized on a cash basis.
A substantial portion of loans are collateralized by real estate in Wisconsin and adjacent states. Accordingly, the ultimate collectability of the loan portfolio is susceptible to changes in real estate market conditions in that area.

Although the Corporation is currently not committed to lend any additional funds on impaired loans in accordance with the original terms of these loans, it is not legally obligated to disburse funds but will, on certain occasions, disburse additional funds to improve our collateral position or reduce our exposure.
The Corporation continues to experience declines in the valuations for real estate collateral supporting portions of its loan portfolio, as reflected in recently received appraisals. Currently, $166.6 million or approximately 89% of the unpaid principal balance of classified loans (i.e. loans risk rated as substandard or loss) have recent appraisals (i.e. within one year) or have been determined to not need an appraisal. Loans that do not require an appraisal under corporate policy include situations in which the loan (i) is fully reserved; (ii) has a small balance (less than $250,000) and rather than being individually evaluated for impairment, is included in a homogenous pool of loans; (iii) uses a net present value of future cash flows to measure impairment; or (iv) is not secured by real estate. Appraised values greater than one year old are discounted by an additional 10% for improved land or commercial real estate and 20% for unimproved land, in determination of the allowance for loan losses.
While corporate policy may not require updated appraisals for these loans, new appraisals may still be obtained. For example, 46% of the loans which do not require an updated appraisal do have either an appraisal within the last year or an appraisal on order. If real estate values decline, the Corporation may have to increase its allowance for loan losses as updated appraisals or other indications of a decrease in the value of collateral are received.

Total delinquencies (loans past due 30 days or more) at September 30, 2013 were $93.8 million. The Corporation has experienced a reduction in delinquencies at each quarter-end since December 31, 2010 due to improving credit conditions and loans moving to OREO. Education loans past due 90 days or more totaling $9.9 million are still accruing interest due to the approximate 97% guarantee provided by governmental agencies. Loans less than 90 days delinquent may be placed on non-accrual status when the probability of collection of principal and interest is deemed to be insufficient to warrant further accrual.
Credit Quality Indicators:
The Corporation groups commercial and industrial loans and commercial real estate loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information and current economic trends, among other factors. This analysis is updated on a monthly basis. The following definitions are used for risk ratings:
Pass. Loans classified as pass represent assets that are evaluated and are performing under the stated terms. Pass rated assets are analyzed by the pay capacity of the obligor, current net worth of the obligor and/or by the value of the loan collateral. A subcategory of loans classified as pass are watch loans.
Watch. Loans classified as watch possess potential weaknesses that require management attention, but do not yet warrant adverse classification. While the status of an asset put on this list does not technically trigger their classification as substandard or non-accrual, it is considered a proactive way to identify potential issues and address them before the situation deteriorates further and results in a loss.
Special Mention. Loans classified as special mention exhibit material negative financial trends due to company specific or industry conditions which, if not corrected or mitigated, threaten their capacity to meet current or continuing debt obligations. These borrowers still demonstrate the financial flexibility to address and cure the root cause of these adverse financial trends without significant deviations from their current business plan. Their potential weakness deserves close attention and warrant enhanced monitoring. The expectation is these borrowers will return to a pass rating given reasonable time; or will be further downgraded.
Substandard. Loans classified as substandard are inadequately protected by the current net worth, paying capacity of the obligor, or by the collateral pledged. Substandard assets must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Corporation will sustain a loss if the deficiencies are not corrected.
Non-Accrual. Loans classified as non-accrual have the weaknesses of those classified as Substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. Loans that fall into this category are deemed collateral dependent and an individual impairment evaluation is performed for all relationships greater than $500,000. Loans in this category are allocated a specific reserve if the collateral does not support the outstanding loan balance or charged off if deemed uncollectible.
As of September 30, 2013 and March 31, 2013, and based on the most recent analysis performed, the risk category of loans by class of loans is as follows:

Troubled Debt Restructurings
Modification of loan terms in a troubled debt restructuring (“TDR”) is generally in the form of an extension of payment terms or lowering of the interest rate, although occasionally the Corporation has reduced the outstanding principal balance.
Loans modified in a troubled debt restructuring that are currently on non-accrual status will remain on non-accrual status for a period of at least six months. If after six months, or a longer period sufficient to demonstrate the willingness and ability of the borrower to perform under the modified terms, the borrower has made payments in accordance with the modified terms, the loan is returned to accrual status but retains its designation as a troubled debt restructuring. The designation as a troubled debt restructuring is removed after the restructuring if both of the following conditions exist: (a) the restructuring agreement specifies an interest rate equal to or greater than the rate that the creditor was willing to accept at the time of restructuring for a new loan with comparable risk and (b) the loan is not impaired based on the terms specified by the restructuring agreement.
The following table presents information related to loans modified in a troubled debt restructuring, by portfolio segment, during the three and six months ended September 30, 2013 and 2012:

Other Real Estate Owned	'
	Note 6 – Other Real Estate Owned
	Real estate acquired by foreclosure or by deed in lieu of foreclosure as well as other repossessed assets (OREO) are held for sale and are initially recorded at fair value less a discount for estimated selling costs at the date of foreclosure. Any write down to fair value less estimated selling costs is charged to the allowance for loan losses. If the discounted fair value exceeds the net carrying value of the loans, recoveries to the allowance for loan losses are recorded to the extent of previous charge-offs, with any excess, which is infrequent, recognized as a gain in non-interest income. Subsequent to foreclosure, valuations are periodically performed and a valuation allowance is established if the carrying value exceeds the fair value less estimated selling costs. Costs relating to the development and improvement of the property may be capitalized. Holding period costs and subsequent changes to the valuation allowance are charged to OREO expense, net included in non-interest expense. Incremental valuation adjustments may be recognized in the Statements of Operations if, in the opinion of management, such additional losses are deemed probable.
	A summary of the activity in other real estate owned is as follows:

	-2	Includes adjustments to the OREO reserve for probable losses.
	-3	Represents the write-down to fair value less estimated selling costs of a loan classified as OREO due to a Bank financed sale of foreclosed property accounted for under the deposit method because of an inadequate down payment by the buyer. The buyer defaulted on this loan and the property has been foreclosed upon and revalued in OREO. The valuation amount includes the write-off of principal and interest payments received over the life of the loan totaling $1.4 million and a charge-off to the Allowance for loan losses of $1.9 million.
	The balances at end of period above are net of a valuation allowance of $34.5 million and $26.2 million at September 30, 2013 and 2012, respectively, recognized during the holding period for declines in fair value subsequent to foreclosure or acceptance of deed in lieu of foreclosure.

Mortgage Servicing Rights	'
	Note 7 – Mortgage Servicing Rights
	Mortgage servicing rights (MSRs) are recorded when loans are sold to third parties with servicing of those loans retained. In addition, MSRs are recorded when acquiring or assuming an obligation to service a financial (loan) asset that does not relate to an asset that is owned. Servicing assets are initially measured at fair value determined using a discounted cash flow model based on market assumptions at the time of origination. Subsequently, the MSR asset is carried at the lower of amortized cost or fair value. MSRs are assessed for impairment using a discounted cash flow model provided by a third party that is based on current market assumptions at the end of each reporting period. For purposes of measuring impairment, the servicing rights are stratified into relatively homogeneous pools based on characteristics such as product type and interest rate bands. Impairment is recognized, if necessary, at the pool level rather than for each individual servicing right asset.
	Accounting for MSRs is based on the amortization method. Under this method, servicing assets are amortized in proportion to and over the period of net servicing income. Income generated as the result of the capitalization of new servicing assets is reported as net gain on sale of loans and the amortization of servicing assets is reported as a reduction to loan servicing income in the consolidated statements of operations. Ancillary income is recorded in other non-interest income.
	Information regarding mortgage servicing rights for the three and six months ended September 30, 2013 and 2012 is as follows:

	Loans intended to be sold are originated in accordance with specific criteria established by the investor agencies – these are known as “conforming loans”. During the sale of these loans, certain representations and warranties are made that the loans conform to these previously established underwriting standards. In the event that a loan is found to be out of compliance with any of these representations and warranties or standards, the Corporation could be responsible for repurchasing the loan at the unpaid principal balance or indemnifying the buyer against loss related to that loan. The expense recorded to indemnify investors for such losses totaled $0.2 million and $0.3 million for the three months ending September 30, 2013 and 2012, respectively, and $0.6 million and $0.5 million for the six months ending September 30, 2013 and 2012, respectively.

	The Bank has entered into agreements with certain brokers that provided deposits obtained from their customers at specified interest rates for an identified fee, or so called “brokered deposits.” At September 30, 2013 and March 31, 2013, the Bank had zero and $100,000 in brokered deposits, respectively. Due to terms of the Cease and Desist Order, the Bank is currently prohibited from obtaining or renewing any brokered deposits. There were no out-of-network certificates of deposit at September 30, 2013. These deposits, which are not considered brokered deposits, are opened via internet listing services and are kept within FDIC insured balance limits.

	The Bank pledges certain loans that meet underwriting criteria established by the FHLB as collateral for outstanding advances. The unpaid principal balance of loans pledged to secure FHLB borrowings totaled $679.0 million and $717.0 million at September 30, 2013 and March 31, 2013, respectively. The FHLB borrowings are also collateralized by mortgage-related securities with a fair value of $129.5 million and $152.1 million at September 30, 2013 and March 31, 2013, respectively.
	On September 19, 2013, FHLB advances totaling $176.0 million were prepaid. The prepaid advances were fixed rate, maturing in 2018, with a then current weighted average rate of 3.18%. The prepayment triggered an early termination penalty of $16.1 million which was recorded in non-interest expense.
	Credit Agreement
	As of March 31, 2013, the Corporation had drawn a total of $116.3 million pursuant to the Amended and Restated Credit Agreement, dated as of June 9, 2008 (as amended from time to time, the “Credit Agreement”) at a weighted average interest rate of 15.00%, on a short term line of credit to various lenders led by U.S. Bank (the “Agent”). On September 27, 2013, pursuant to the Plan of Reorganization, the Corporation satisfied all of our obligations under the Credit Agreement by a cash payment to the Lenders of $49.0 million (plus expense reimbursement as contemplated by the Credit Agreement).

Regulatory Capital	'
	Note 11 – Regulatory Capital
	The Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary actions by bank regulators that, if undertaken, could have a direct material effect on the Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank’s assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.
	Qualitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios of core, tangible, and risk-based capital. At September 30, 2013, the Bank had a tier 1 leverage (core) ratio of 9.06% and a total risk-based capital ratio of 16.30%, each meeting the required capital ratios set forth above. As a result of the Plan of Reorganization and the recapitalization of the Bank, the Bank is in compliance with the tier 1 (core) leverage and total risk-based capital ratios as required by the Bank Order. See Note 2.
	The following table summarizes the Bank’s capital ratios and the ratios required by its federal regulators to be considered adequately or well capitalized under standard regulatory guidelines and as required by the Cease and Desist Order at September 30, 2013 and March 31, 2013:

Commitments and Contingent Liabilities	'
	Note 12 – Commitments and Contingent Liabilities
	The Corporation is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and financial guarantees which involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets. The contract amounts of those instruments reflect the extent of involvement and exposure to credit loss the Corporation has in particular classes of financial instruments. The same credit policies are used in making commitments and conditional obligations as for on-balance-sheet instruments. Since many of the commitments are expected to expire without being drawn upon, the total committed amounts do not necessarily represent future cash requirements.
	Financial instruments whose contract amounts represent credit risk are as follows:
		September 30,		March 31,
		2013		2013
		(In thousands)
	Commitments to extend credit	$	39,246	$	34,697
	Unused commitments		469		—
	Unused lines of credit:
	Home equity		104,609		108,628
	Credit cards		22,551		28,541
	Commercial		50,217		15,666
	Letters of credit		16,659		15,546
	Credit enhancement under the Federal Home Loan Bank of Chicago Mortgage Partnership Finance Program		15,877		15,877
	Commitments to extend credit are in the form of a loan in the near future. Unused commitments include closed residential mortgage loans in the recission period. Unused lines of credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract and may be drawn upon at the borrowers’ discretion. Letters of credit commit the Corporation to make payments on behalf of customers when certain specified future events occur. Commitments and letters of credit primarily have fixed expiration dates or other termination clauses and may require payment of a fee. As some such commitments expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Corporation evaluates each customer’s creditworthiness on a case-by-case basis. With the exception of credit card lines of credit, the Corporation primarily extends credit on a secured basis. Collateral obtained consists primarily of single-family residences and income-producing commercial properties.
	At September 30, 2013, the Corporation has $7.3 million of reserves on unfunded loan commitments, unused lines of credit, letters of credit and repurchase of sold loans classified in other liabilities. The Corporation intends to fund commitments through current liquidity.
	The Bank previously participated in the Mortgage Partnership Finance (MPF) Program of the Federal Home Loan Bank of Chicago (FHLB). The program was intended to provide member institutions with an alternative to holding fixed-rate mortgages in their loan portfolios or selling them in the secondary market. An institution participates in the MPF Program by either originating individual loans on a “flow” basis as agent for the FHLB pursuant to the “MPF 100 Program” or by selling, as principal, closed loans owned by an institution to the FHLB pursuant to one of the FHLB’s closed-loan programs. The program was discontinued in 2008 in its present format and the Bank no longer funds loans through the MPF program. The Bank does, however, continue to service the loans funded under the program and maintains the credit exposure and credit enhancement fees. Under the MPF Program, credit risk is shared by the participating institution and the FHLB by structuring the loss exposure in several layers, with the participating institution being liable for losses after application of an initial layer of losses (after any private mortgage insurance) is absorbed by the FHLB, subject to an agreed-upon maximum amount of such secondary credit enhancement which is intended to be in an amount equivalent to a “AA” credit risk rating by a rating agency. The participating institution receives credit enhancement fees from the FHLB for providing this credit enhancement and continuing to manage the credit risk of the MPF Program loans. Participating institutions are also paid specified servicing fees for servicing the loans.
	Pursuant to a credit enhancement feature of the MPF program, the Corporation has retained secondary credit loss exposure in the amount of $15.9 million at September 30, 2013 related to approximately $227.6 million of residential mortgage loans that the Bank has originated as agent for the FHLB. Under the credit enhancement, the FHLB is liable for losses on loans up to one percent of the original delivered loan balances in each pool. The Bank is then liable for losses over and above the first position up to a contractually agreed-upon maximum amount in each pool that was delivered to the Program. The Corporation receives a monthly fee for this credit enhancement obligation based on the outstanding loan balances. The Corporation has recorded net credit enhancement fee income from this program totaling $6,400 and $7,600 for the six month periods ending September 30, 2013 and 2012, respectively. Based on historical experience, the Corporation does not anticipate that any credit losses will be incurred under the credit enhancement obligation.
	Other loans sold to investors with recourse to the Corporation met the underwriting standards of the investor and the Corporation at the time of origination. In the event of default by the borrower, the investor may resell the loans to the Corporation at par value. As the Corporation expects relatively few such loans to become delinquent, the total amount of loans sold with recourse does not necessarily represent future cash requirements. Collateral obtained on such loans consists primarily of single-family residences. The unpaid principal balance of loans repurchased from investors totaled $376,000 and $714,000 for the three months ending September 30, 2013 and 2012, respectively and $604,000 and $1.4 million for the six months ending September 30, 2013 and 2012, respectively. Alternatively, investors make requests to be made whole on a loan whereby the property has been disposed of at a loss. The related expense was $223,000 and $265,000 for the three months ending September 30, 2013 and 2012, respectively and $594,000 and $491,000 for the six months ending September 30, 2013 and 2012, respectively.
	In the ordinary course of business, there are legal proceedings against the Corporation and its subsidiaries. Management considers that the aggregate liabilities, if any, resulting from such actions would not have a material, adverse effect on the consolidated financial position of the Corporation.
	One pending lawsuit against the Corporation currently in the discovery stage involves a Bank-issued letter of credit in support of a residential real estate development. A specific reserve for loss on unfunded loan commitments has been established at June 30, 2013 in the amount of $2.4 million due to a shortfall in the value of the residential real estate development supporting the letter of credit, $1.7 million of which was recorded during the quarter ended June 30, 2013.

Derivative Financial Instruments	'
	Note 13 – Derivative Financial Instruments
	The Corporation enters into contracts that meet the definition of derivative financial instruments in accordance with ASC 815 – Derivative and Hedging. Derivatives are used as part of a risk management strategy to address exposure to changes in interest rates inherent in the Corporation’s origination and sale of certain residential mortgages into the secondary market. These derivative contracts used for risk management purposes include: (1) interest rate lock commitments provided to customers to fund mortgage loans intended to be sold; and (2) forward sale contracts for the future delivery of funded residential mortgages.
	Forward sale contracts are entered into when interest rate lock commitments are granted to customers in an effort to economically hedge the effect of future changes in interest rates on the commitments to fund mortgage loans intended to be sold (the “pipeline”), as well as on the portfolio of funded mortgages not yet sold (the “warehouse”). For accounting purposes, these derivatives are not designated as being in a hedging relationship. The contracts are carried at fair value on the consolidated balance sheets, with changes in fair value recorded in the consolidated statements of operations.

	(2)	The Corporation recognizes fair value of unused commitments held for trading which consists of closed residential real estate loans still in recission at period end.

Fair Value Disclosures [Abstract]	'
Fair Value of Financial Instruments	'
	Note 14 – Fair Value of Financial Instruments
	ASC Topic 820 establishes a framework for measuring fair value and disclosures about fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.
	In determining fair value, various valuation methods are used including market, income and cost approaches. Assumptions that market participants would use in pricing the asset or liability are utilized in these valuation methods, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs may be readily observable, market corroborated or generally unobservable inputs. Valuation methodologies are employed that maximize the use of observable inputs and minimize the use of unobservable inputs. Based on observability of the inputs used in the valuation methodologies, financial assets and liabilities measured at fair value on a recurring and nonrecurring basis are categorized according to the fair value hierarchy. The fair value hierarchy ranks the quality and reliability of the information used to determine fair values. Financial assets and liabilities that are adjusted to fair value are classified in one of the following three categories:
		•		Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date.
		•		Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.
		•		Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.
	Fair Value on a Recurring Basis

Loans held for sale consist primarily of the current origination of certain fixed- and adjustable-rate residential mortgage loans and effective April 1, 2013 are carried at fair value with no deferral of fees or costs, determined on a loan by loan basis.
Prior to April 1, 2013, these loans were carried at the lower of cost or fair value. These loans were valued individually based upon quoted market prices for similar loans and the amount of any gross loss was recorded as a valuation allowance in loans held for sale. Fees received from the borrower and direct costs to originate the loan were deferred and recorded as an adjustment to the loan carrying value. Valuation adjustments were included in the statement of operations in net gain on the sale of loans.

Other assets and other liabilities include interest rate lock commitments provided to customers to fund mortgage loans intended to be sold and forward sale contracts for future delivery of funded residential mortgages to investors. The Corporation relies on an internal valuation model to estimate the fair value of its interest rate lock commitments, which includes applying an estimated pull-through rate (the percentage of commitments expected to result in a closed loan) based on historical experience; multiplied by quoted investor prices on closed loans for future delivery determined to be reasonably applicable to the loan commitment based on interest rate, terms and rate lock expiration.
The Corporation also relies on an internal valuation model to estimate the fair value of its forward contracts to sell residential mortgage loans (i.e., an estimate of what the Corporation would receive or pay to terminate the forward delivery contract) based on market prices for similar financial instruments, which includes matching specific terms and maturities of the forward commitments against applicable investor pricing available.

There were no transfers in or out of Levels 1, 2 or 3 during the quarter ended September 30, 2013 and fiscal year ended March 31, 2013. The Corporation’s policy for determining transfers between levels occurs at the end of the reporting period when circumstances in the underlying valuation criteria changes and result in transfers between levels.
Fair Value on a Nonrecurring Basis
Certain assets are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). Loans held for sale and mortgage servicing rights includes only those items that were adjusted to fair value as of the dates indicated. The following table presents such assets carried on the consolidated balance sheet by caption and by level within the fair value hierarchy as of September 30, 2013 and March 31, 2013:

-1	Effective April 1, 2013, loans held for sale are recorded at fair value and therefore are reflected in the table of financial instruments carried at fair value for the period ended September 30, 2013.
The Corporation does not adjust loans held for investment to fair value on a recurring basis. However, some loans are considered impaired and an allowance for loan losses is established. The specific reserves for collateral dependent impaired loans are based on the fair value of the underlying collateral less estimated costs to sell. The fair value of collateral is usually determined based on appraisals. In some cases, adjustments are made to appraised values due to various factors including age of the appraisal, age of comparables included in the appraisal, and known changes in the market and in the collateral. Since adjustments to appraised values are based on unobservable inputs, the resulting fair value measurement is categorized as a Level 3 measurement.
Mortgage servicing rights are recorded as an asset when loans are sold to third parties with servicing rights retained. Mortgage servicing rights are initially recorded at fair value and subsequently amortized in proportion to, and over the period of, estimated net servicing revenues. The carrying value of these assets is reviewed for impairment on a monthly basis using a lower of carrying value or fair value methodology. The fair value of servicing rights is determined by estimating the present value of future net cash flows using a discounted cash flow model, taking into consideration market loan prepayment speeds, discount rates, servicing costs and other economic factors. For purposes of measuring impairment, the rights are stratified based on predominant risk characteristics of the underlying loans which include product type (i.e., fixed, adjustable or balloon) and interest rate bands. If the aggregate carrying value of the capitalized mortgage servicing rights for a stratum exceeds its fair value, the difference is recognized in non-interest expense as an impairment loss.
Critical assumptions used in the MSR discounted cash flow model include mortgage prepayment speeds, discount rates, costs to service, ancillary and late fee income. Variations in the assumptions could materially affect the estimated fair values. Changes to the assumptions are made when market data indicate that new trends have developed. Current market participant assumptions based on loan product types – fixed rate, adjustable rate and balloon loans – include discount rates in the range of 10.0% to 23.5% as well as total portfolio lifetime weighted average prepayment speeds of 7.2% to 50.5% annual CPR. Many of these assumptions are subjective and involve a high degree of management judgment. MSR valuation assumptions are reviewed and approved by management on a quarterly basis.
Prepayment speeds may be affected by economic factors such as changes in home prices, market interest rates, the availability of other credit products to borrowers and customer payment patterns. Prepayment speeds include the impact of all borrower prepayments, including full payoffs, additional principal payments and the impact of loans paid off due to foreclosure liquidations. As market interest rates decline, prepayment speeds will generally increase as customers refinance existing mortgages to more favorable interest rate terms. As prepayment speeds increase, anticipated cash flows will generally decline resulting in a potential reduction, or impairment, of the fair value of the capitalized MSRs. Alternatively, an increase in market interest rates may cause a decrease in prepayment speeds and therefore an increase in fair value of MSRs. Annually, external data is obtained to test the values and assumptions that are used for the initial valuations in the discounted cash flow model.
Real estate acquired by foreclosure, real estate acquired by deed in lieu of foreclosure and other repossessed assets (OREO) are held for sale and are initially recorded at fair value less estimated selling expenses at the date of foreclosure. OREO is re-measured at the lower of cost or fair value after initial recognition and reported using a valuation allowance on foreclosed assets. Fair value is generally based on third party appraisals and is therefore considered a Level 3 measurement.
Fair Value Summary
ASC Topic 825 requires disclosure of fair value information about financial instruments, for which it is practicable to estimate that value, whether or not recognized in the consolidated balance sheets, including those financial assets and liabilities that are not measured and reported at fair value on a recurring or nonrecurring basis. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Results from these techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, may not be realized in immediate settlement of the instruments. Certain financial instruments with a fair value that is not practicable to estimate and allnon-financial instruments are excluded from the disclosure requirements. Accordingly, the aggregate fair value amounts presented in the table below do not necessarily represent the underlying value of the Corporation.
The following methods and assumptions were used in estimating the fair value of financial instruments that were not previously disclosed:
Cash and cash equivalents and accrued interest: The carrying amounts reported in the balance sheets approximate the fair values for those assets and liabilities. In accordance with ASC Topic 820, cash and cash equivalents and accrued interest have been categorized as a Level 2 fair value measurement.
Loans receivable: The fair value of residential mortgage loans held for investment, commercial real estate loans, commercial and industrial loans, and consumer and other loans held for investment are estimated using observable inputs including estimated cash flows, and discount rates based on interest rates currently being offered for loans with similar terms, to borrowers of similar credit quality. In accordance with ASC Topic 820, loans held for investment that are not included with impaired loans in the preceding section titled Fair Value on a Nonrecurring Basis have been categorized as a Level 2 fair value measurement.
Federal Home Loan Bank stock: The carrying amount of FHLB stock approximates its fair value as it can only be redeemed with the FHLB at par value. In accordance with ASC Topic 820, Federal Home Loan Bank stock has been categorized as a Level 2 fair value measurement.
Deposits: The fair value for deposit accounts with no defined maturities, such as demand deposits, savings, and money market accounts, is equal to their carrying amounts, which represents the amount payable on demand. Fair value for certificates of deposit, with stated maturities, is estimated using a discounted cash flow calculation based on contractual cash flows. The discount rate is estimated using incremental borrowing rates for similar terms. In accordance with ASC Topic 820, deposits have been categorized as a Level 2 fair value measurement.
Other borrowed funds: The fair value of FHLB advances is obtained from the Federal Home Loan Bank, which uses a discounted cash flow analysis based on current market rates for borrowings with similar terms. Repurchase agreements are estimated using discounted cash flow analysis, based on the Corporation’s current incremental borrowing rates for similar types of borrowing arrangements. In the absence of a reasonably precise methodology to determine the fair value of the credit agreement, carrying value has been used to represent fair value. In accordance with ASC Topic 820, other borrowed funds have been categorized as a Level 2 fair value measurement.
Off-balance-sheet instruments: The fair value of off-balance-sheet instruments (held for investment lending commitments and unused lines of credit) are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements, the counterparties’ credit standing and discounted cash flow analyses. The fair value of these off-balance-sheet items approximates the recorded amounts of the related fees and is not material at September 30, 2013 and March 31, 2013.

Income Tax Disclosure [Abstract]	'
Income Taxes	'
	Note 15 – Income Taxes
	The Corporation accounts for income taxes based on the asset and liability method. Deferred tax assets and liabilities are recorded based on the difference between the tax basis of assets and liabilities and their carrying amounts for financial reporting purposes, computed using enacted tax rates. Significant net deferred tax assets have been created for net operating loss (NOL) carryforwards and deductible temporary differences, the largest of which relates to our allowance for loan losses. For income tax purposes, only net charge-offs on uncollectible loans are deductible, not the provision for loan losses.
	Under generally accepted accounting principles, a valuation allowance is required to be recognized if it is “more likely than not” that a deferred tax asset will not be realized. The determination of the realizability of the deferred tax assets is highly subjective and dependent upon management’s evaluation and judgment of both positive and negative evidence, the forecasts of future income, applicable tax planning strategies, and assessments of the current and future economic and business conditions. The Corporation considers both positive and negative evidence regarding the ultimate realizability of deferred tax assets. Positive evidence includes the existence of taxes paid in available carry back years as well as the probability that taxable income will be generated in future periods while negative evidence includes significant losses or cumulative losses in the past several years as well as general business and economic trends.
	At September 30, 2013 and March 31, 2013, the Corporation determined that a valuation allowance relating to the deferred tax asset was necessary. This determination was based largely on the negative evidence represented by the losses in the prior fiscal years caused by the significant loss provisions associated with the loan portfolio. In addition, general uncertainty surrounding future economic and business conditions increase the potential volatility and uncertainty of projected earnings. Therefore, a valuation allowance of $121.4 million and $162.1 million at September 30, 2013 and March 31, 2013, respectively, was recorded to offset net deferred tax assets.
	The significant components of the Corporation’s deferred tax assets (liabilities) are as follows:

	At March 31, 2013, the Corporation had $278.2 million in federal net operating loss carryforwards (NOLs) which were available to offset future taxable income. A portion of the NOL’s totaling $134.5 million were utilized as part of the reorganization related to the gain on the extinguishment of debt reducing the federal NOLs to $143.7 million. The remaining carryforwards expire in varying amounts through 2033.
	The Corporation is subject to U.S. federal income tax as well as income tax of state jurisdictions. The tax years 2010-2013 remain open to examination by the Internal Revenue Service and certain state jurisdictions while the years 2009-2013 remain open to examination by certain other state jurisdictions.
	The Corporation recognizes interest and penalties related to uncertain tax positions in income tax expense. As of September 30, 2013 and March 31, 2013, the Corporation has not recognized any accrued interest and penalties related to uncertain tax positions.

Earnings Per Share	'
	Note 16 – Earnings Per Share
	Basic earnings per share for the three and six months ended September 30, 2013 and 2012 has been determined by dividing net income (loss) available to common equity for the respective periods by the weighted average number of shares of common stock outstanding. Diluted earnings per share is computed by dividing net loss available to common equity by the weighted average number of common shares outstanding plus the effect of dilutive securities. The effects of dilutive securities are computed using the treasury stock method.
	The computation of earnings per share for the three and six months ended September 30, 2013 and 2012 is as follows:

	‘(1)	Shares issued pursuant to the Plan of Reorganization of 1.81 billion were subsequently adjusted to 9.05 million as a result of a reverse stock split effected on October 2, 2013 by an amendment to the Certification of Incorporation of Anchor Bancorp Wisconsin Inc. The calculation of weighted average shares included 21,247,000 outstanding through September 26 and 9,050,000 from September 27 through September 30, 2013.
	At September 30, 2013, there were no outstanding stock options. Prior period stock option balances were excluded from the calculation of diluted earnings per share because they were anti-dilutive. Additionally, for periods prior to September 30, 2013, the TARP Warrants (see Note 10) were also not included in the computation of diluted earnings per share because the TARP Warrants’ per share exercise price of $2.23 was greater than the average market price of common stock and, therefore, anti-dilutive.
	As previously described in Note 2 under the caption TARP Exchange, the difference between the common stock issued and the preferred stock redeemed of $104.0 million was recorded as an increase directly to retained earnings. The $104.0 million represents a return from the Preferred stockholder thereby increasing the amount available to Common stockholders for purposes of earnings per share. Accordingly, there is $104.0 million included above in the numerator for basic and diluted earnings per share – income (loss) available to common stockholders in both the three and the six months ended September 30, 2013 related to the TARP Exchange. Although EPS information for the three and six months ended September 30, 2012 is presented, it is not comparable to the information presented for the current year periods due to the changes in our capital structure resulting from the Plan of Reorganization.

Regulatory Agreements	'
	Regulatory Agreements
	The Bank’s primary regulator is the Office of the Comptroller of the Currency (“OCC”). The Federal Reserve is the primary regulator of the Corporation. On September 26, 2009, the Corporation and the Bank each consented to the issuance of an Order to Cease and Desist (the “Corporation Order” and the “Bank Order,” respectively, and together, the “Orders”).
	The Corporation Order requires the Corporation to notify, and in certain cases to obtain the permission of, the Federal Reserve prior to: (i) declaring, making or paying any dividends or other capital distributions on its capital stock, including the repurchase or redemption of its capital stock; (ii) incurring, issuing, renewing or rolling over any debt, increasing any current lines of credit or guaranteeing the debt of any entity; (iii) making certain changes to its directors or senior executive officers; (iv) entering into, renewing, extending or revising any contractual arrangement related to compensation or benefits with any of its directors or senior executive officers; and (v) making any golden parachute payments or prohibited indemnification payments. In July 2010, the Corporation developed and submitted to the Office of Thrift Supervision, the Corporation’s primary regulator at the time until it was disbanded in 2011 and the Federal Reserve assumed the role of primary regulator, a three-year cash flow plan, which must be reviewed at least quarterly by the Corporation’s management and board of directors for material deviations between cash flow plan projections and actual results (the “Variance Analysis Report”). Within 45 days following the end of each quarter, the Corporation is required to provide and has been providing the Federal Reserve its Variance Analysis Report for that quarter.
	The Bank Order requires the Bank to notify, or in certain cases obtain the permission of, the OCC prior to (i) increasing its total assets in any quarter in excess of an amount equal to net interest credited on deposit liabilities during the quarter; (ii) accepting, rolling over or renewing any brokered deposits; (iii) making certain changes to its directors or senior executive officers; (iv) entering into, renewing, extending or revising any contractual arrangement related to compensation or benefits with any of its directors or senior executive officers; (v) making any golden parachute or prohibited indemnification payments; (vi) paying dividends or making other capital distributions on its capital stock; (vii) entering into certain transactions with affiliates; and (viii) entering into third-party contracts outside the normal course of business. The Bank also developed and submitted within the prescribed time periods, a written capital restoration plan, a problem asset plan, a revised business plan, and an implementation plan resulting from a review of commercial lending practices. The Orders also require the Bank to regularly review its current liquidity management policy and the adequacy of its allowance for loan and lease losses.
	The Bank is also subject to a capital restoration plan including a Prompt Corrective Action Directive (“PCA”). Under the PCA, the Bank must obtain prior written approval before entering into any contract or lease for the purchase or sale of real estate or of any interest therein, except for contracts entered into in the ordinary course of business for the purchase or sale of other real estate owned due to foreclosure (“OREO”) where the contract does not exceed $3.5 million and the sales price of the OREO does not fall below 85% of the net carrying value of the OREO.
	The Orders also stipulated that, as of September 30, 2009, the Bank was required to meet and maintain both a core capital ratio equal to or greater than 7% and a total risk-based capital ratio equal to or greater than 11%. Further, as of December 31, 2009, the Orders required the Bank to meet and maintain both a core capital ratio equal to or greater than 8% and a total risk-based capital ratio equal to or greater than 12%.
	As disclosed above and in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Form 10-Q, on September 27, 2013, pursuant to a pre-packaged plan of reorganization (the “Plan of Reorganization”) to facilitate the restructuring of the Corporation and the recapitalization of the Bank, the Corporation completed a capital raise and received gross proceeds of $175.0 million. See “Executive Overview.”
	At September 30, 2013, the Bank had a tier 1 leverage (core) ratio of 9.06% and a total risk-based capital ratio of 16.30%, each meeting the required capital ratios set forth above. As a result of the Plan of Reorganization and the recapitalization of the Bank, the Bank is in compliance with the tier 1 (core) leverage and total risk-based capital ratios as required by the Bank Order. All customer deposits remain fully insured to the highest limits set by the FDIC.
Going Concern	'
	Going Concern
	Our March 31, 2013 audit opinion contained a going concern matter due to the previous default on our credit agreement and inability to meet minimum capital requirements. During the most recent quarters, the following events and transactions occurred to address those concerns: On August 12, 2013, the Company filed a voluntary petition for relief under the provisions of Chapter 11 of Title 11 of the Bankruptcy Code in the United States Bankruptcy Court for the Western District of Wisconsin to implement a pre-packaged plan of reorganization (the “Plan of Reorganization”) in order to facilitate the restructuring of the Company and the recapitalization of the Bank.
	On August 30, 2013, the Bankruptcy Court entered the Confirmation Order, by which it confirmed the Plan of Reorganization. As disclosed above and in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Form 10-Q, on September 27, 2013, pursuant to the Plan of Reorganization, the Corporation completed a capital raise and received gross proceeds of $175.0 million. See “Executive Overview.” As a result of the Plan of Reorganization and the recapitalization of the Bank, the Bank is in compliance with the tier 1 (core) leverage and total risk-based capital ratios as required by the Bank Order.
	On September 27, 2013, pursuant to the Plan of Reorganization, the Corporation (i) exchanged the TARP Preferred Stock for 60.0 million shares of common stock (adjusted to 300,000 shares as a result of the reverse stock split) and (ii) cancelled the TARP Warrant in its entirety. Further, the Corporation has settled its obligations under the Amended and Restated Credit Agreement (“Credit Agreement”) among the Corporation, the lenders from time to time a party thereto, and U.S. Bank National Association, as administrative agent for such lenders.
Credit Risks	'
	Credit Risks
	Non-performing assets totaled $162.9 million at September 30, 2013, or 7.43% of total assets, which decreased the Corporation’s interest income. The Corporation’s results of operations will continue to be impacted by the level of non-performing assets, and the Corporation expects continued downward pressure on interest income in the future. As reported in the accompanying unaudited consolidated financial statements, the Corporation has net income of $113.3 million and $107.9 million for the three and six month periods ended September 30, 2013, respectively, and net losses of $8.6 million and $8.5 million for the three and six months ended September 30, 2012, respectively. Stockholders’ equity increased from a deficit of $59.9 million or (2.53)% of total assets at March 31, 2013 to $201.0 million or 9.18% of total assets at September 30, 2013.
Presentation of Unrecognized Tax Benefit	'
	ASU 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. ASU 2013-11 requires that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit shall be presented in the financial statements as a liability and shall not be combined with deferred tax assets. The assessment of whether a deferred tax asset is available is based on the unrecognized tax benefit and deferred tax asset that exist at the reporting date and shall be made presuming disallowance of the tax position at the reporting date. The amendments do not require new recurring disclosures.
Creditor's Determination of Whether Restructuring Is Troubled Debt Restructuring	'
	ASU No. 2013-02, “Comprehensive Income (Topic 220) – Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.” ASU 2013-02 requires entities to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under U.S. generally accepted accounting principles (GAAP) to be reclassified in its entirety to net income. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under U.S. GAAP that provide additional detail about those amounts. This would be the case when a portion of the amount reclassified out of accumulated other comprehensive income is reclassified to a balance sheet account instead of directly to income or expense in the same reporting period.
