Accounting Policies [Abstract]
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 “Company”, “we”, “our”) and its wholly-owned subsidiaries, AnchorBank, fsb (the “Bank”) and Investment Directions, Inc. (“IDI”). The Bank has one subsidiary: 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 under the Securities Exchange Act of 1934, as amended. 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 consolidated 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 fair value of investment securities, 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. The results of operations and other data for the three month period ended March 31, 2015 are not necessarily indicative of results that may be expected for the year ending December 31, 2015. We have evaluated all subsequent events through the date of this filing. See Note 18-Subsequent Events to the Unaudited Consolidated Financial Statements. 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 Company’s Annual Report on Form 10-K for the year ended December 31, 2014.
	Reclassifications. Certain prior period amounts are reclassified to conform to the current period presentations with no impact on net income or total stockholders’ equity when applicable.

Text Block [Abstract]
Significant Transactions	Note 2 – Significant Transactions

	Management regularly and periodically evaluates and assesses all aspects of the Bank’s operations, including, but not limited to, retail branch delivery and placement of its support functions, for opportunities to improve the profitability of the Company. In the case of branch delivery, this could include the closure, sale or other disposal of a branch or addition to the current branch structure.

	Sale of Branch

	On January 27, 2015, the Bank announced the sale of its Viroqua branch to another bank located in Wisconsin. The purchasing bank will assume approximately $12.0 million in deposits along with loans and other assets. The transaction is subject to regulatory approval and customary closing conditions and is targeted to close by the end of May 2015.

	Credit Card Arrangement

	Credit is extended to Bank customers through credit cards issued by a third party, ELAN Financial Services (“ELAN”), pursuant to an agency arrangement. A new agreement was signed with ELAN effective January 1, 2015 providing the Bank an origination fee for each card issued. The Bank also receives a monthly fee from ELAN resulting from the performance of the originated portfolio, based on 11% of the interest income and 25% of the interchange income. As part of the new agreement, the Bank agreed to sell back to ELAN its participation in outstanding credit card balances totaling $6.7 million with no gain or loss recognized. The Bank is therefore no longer exposed to credit risk from the underlying consumer credit.

	Prior to January 1, 2015 credit was extended to Bank customers through credit cards issued by a third party, ELAN Financial Services (“ELAN”), pursuant to an agency arrangement under which the Company participated in outstanding balances, at levels of 25% to 28%. The Company also shared 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 net of our share of losses. This agreement expired on December 31, 2014.



	Purchase of New Building

	On January 28, 2015 the Bank completed the purchase of a new building located on the east side of Madison, Wisconsin at a purchase price of $4.0 million. This facility will house a number of support departments involving approximately 200 employees. Management believes this move should improve workgroup efficiencies. Facility improvements continue to progress in preparation for a second quarter move.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	Note 3 – Recent Accounting Pronouncements

	Accounting Standards Update, (“ASU”), No. 2015-03 “Interest-Imputation of Interest (Subtopic 835-30).” ASU 2015-03 simplifies the presentation of debt issuance costs, requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. This amendment is effective for fiscal years beginning after December 15, 2015 and interim periods within those fiscal years. Early adoption is permitted for financial statements that have not been previously issued. Entities should apply the new guidance on a retrospective basis, wherein the balance sheet of each individual period presented should be adjusted to reflect the period-specific effects of applying the new guidance. The Company intends to adopt the accounting standard during the first quarter of 2016, as required, with no material impact.

	ASU, No. 2015-02 “Consolidation (Topic 810).” ASU 2015-02 is an amendment to the consolidation process and addresses the current accounting for consolidation of certain legal entities. All legal entities are subject to reevaluation under the revised consolidation model. The new standard reduces the number of consolidation models from four to two, simplifying consolidation by placing more emphasis on risk of loss when determining a controlling financial interest, reducing the frequency of the application of related-party guidance when determining a controlling financial interest in a variable interest entity and changing consolidation conclusions in several industries that typically make use of limited partnerships or VIEs. This amendment is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. Entities may apply the amendment prospectively or retrospectively to all prior periods presented in the financial statements. Early adoption is permitted provided that the guidance is applied from the beginning of the year of adoption. The Company intends to adopt the accounting standard during the first quarter of 2016, as required, with no material impact.

	ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606).” In May 2014, the Financial Accounting Standards Board (“FASB”) issued an amendment to clarify the principles for recognizing revenue and to develop a common revenue standard. The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that “an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” In applying the revenue model to contracts within its scope, an entity should apply the following steps: (1) Identify the contract(s) with a customer, (2) Identify the performance obligations in the contract, (3) Determine the transaction price, (4) Allocate the transaction price to the performance obligations in the contract, and (5) Recognize revenue when (or as) the entity satisfies a performance obligation. The standard applies to all contracts with customers except those that are within the scope of other topics in the FASB Codification. The standard also requires significantly expanded disclosures about revenue recognition. The amendment is effective for annual reporting periods beginning after December 15, 2016 (including interim reporting periods within those periods). Early application is not permitted. The Company intends to adopt the accounting standard during the first quarter of 2017, as required, and is currently evaluating the impact on its results of operations, financial position, and liquidity. The FASB on April 1, 2015 agreed to propose a delay of its revenue recognition standard by one year effective for adoption for annual periods beginning after December 15, 2017.

	Management evaluates securities for other-than-temporary impairment (“OTTI”) 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 Company to retain its investment for a period of time sufficient to allow for any anticipated recovery in fair value.

	At March 31, 2015 and December 31, 2014, there were no securities classified as other-than-temporarily impaired. Unrealized other-than-temporary impairment due to credit losses of $21,000 was included in earnings for the three months ended March 31, 2014. For the three months ended March 31, 2014 realized losses of $63,000 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. During December 2014, these other-than-temporarily impaired securities were sold at a loss of $37,000.

Unrealized losses on U.S. government sponsored and federal agency obligations, other securities and Ginnie Mae mortgage-backed securities as of March 31, 2015 and December 31, 2014 due to changes in interest rates and other non-credit related factors totaled $1.5 million and $3.2 million, respectively. The number of individual securities in the tables above total 23 at March 31, 2015 and 34 at December 31, 2014. The Company 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 (loss).



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 (loss) for the period presented:

	(1)	Undisbursed loan proceeds are funds to be released upon a draw request approved by the Company.
	Residential Loans
	At March 31, 2015, $537.0 million, or 34.3%, of the total gross loans 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 were originated with up to 30-year maturities and terms which provide for annual increases or decreases of 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 Company does not originate negative amortization and option payment adjustable rate mortgages.
	At March 31, 2015, approximately $309.2 million, or 57.6%, of the held for investment residential gross loans consisted of loans with adjustable interest rates. At March 31, 2015, approximately $227.8 million, or 42.4%, of the held for investment residential gross loans 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 shorter period of time.
	Commercial and Industrial Loans
	The Company originates loans for commercial and business purposes, including issuing letters of credit. At March 31, 2015, the commercial and industrial gross loans amounted to $17.7 million, or 1.1%, of the total gross loans.
	Commercial Real Estate Loans
	At March 31, 2015, $687.6 million of gross loans were secured by commercial real estate, which represented 44.0% of the total gross loans. The origination of such loans is generally limited to the Company’s primary market area.

	Consumer Loans
	The Company offers consumer loans in order to provide a wider range of financial services to its customers. Consumer loans primarily consist of home equity loans and lines and education loans. At March 31, 2015, $324.4 million, or 20.6%, of the total gross loans consisted of consumer loans.
	Approximately $103.5 million, or 6.6%, of the total gross loans at March 31, 2015 consisted of education loans. The origination of student loans was discontinued October 1, 2010 following the March 2010 law ending loan guarantees provided by the U.S. Department of Education. Both the principal amount of an education loan and interest on loans originated prior to March 2010 thereon are generally guaranteed by the U. S. Department of Education up to a minimum of 97% of the balance of the loan. Education loans are serviced by Great Lakes Higher Education and may be sold to the U.S. Department of Education or to other investors. No education loans were sold during the three months ended March 31, 2015 or 2014.
	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.
	Other consumer loans consist of vehicle loans and other secured and unsecured loans made for a variety of consumer purposes.
	Credit is extended to Bank customers through credit cards issued by a third party, ELAN Financial Services (ELAN), pursuant to an agency arrangement. The Bank exited the credit card portfolio by executing a new agreement with ELAN on December 31, 2014 effective January 1, 2015. As part of the new agreement, the Bank sold back to ELAN its participation in outstanding credit card balances totaling $6.7 million with no gain or loss recognized. This transaction settled on February 10, 2015.

Total delinquencies (loans past due 30 days or more) at March 31, 2015 were $21.0 million. Non-accrual loans were $25.1 million and $35.1 million as of March 31, 2015 and December 31, 2014, respectively. The Company has experienced a reduction in delinquencies since December 31, 2014 primarily due to improving credit conditions and $1.3 million of loans moving to OREO. The Company has $5.4 million of education loans past due 90 days or more at March 31, 2015 that 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 Company classifies 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.
Watch. Loans classified as watch possess potential weaknesses that require management attention, but do not yet warrant adverse classification. These loans are treated the same as loans classified as “Pass” for reporting purposes.
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.
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.

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.
The risk category of loans by class of loans, and based on the most recent analysis performed, is as follows:


		Pass (1)				Special				Substandard			Non-Accrual			Total Gross
		Pass (1)				Mention				Substandard			Non-Accrual			Loans

(2)	Non-accrual education loans represent the portion of these loans 90+ days past due that are not covered by a guarantee provided by government agencies that is limited to approximately 97% of the outstanding balance.

Troubled Debt Restructurings
Modifications of loan terms in a TDR are generally in the form of an extension of payment terms or lowering of the interest rate, although occasionally the Company 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, or longer period, sufficient to prove that the borrower demonstrates that they can make the payments under the modified terms. If after this period, the borrower has made payments in accordance with the modified terms, the loan is returned to accrual status but retains its designation as a TDR. Once a TDR loan is returned to accrual, further review of the credit could take place resulting in a further upgrade into the pass category but still remaining as a TDR.
The following table presents information related to loans modified in a troubled debt restructuring by class:

Mortgage Servicing Rights	Note 7 - Mortgage Servicing Rights

	Accounting for mortgage loan servicing rights (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 income. Ancillary income is recorded in other non-interest income.

	Information regarding the Company’s mortgage servicing rights is as follows:

	FHLB Advances

	The Bank pledges certain loans that meet underwriting criteria established by the Federal Home Loan Bank of Chicago (“FHLB of Chicago”) as collateral for outstanding advances. The unpaid principal balance of loans pledged to secure FHLB of Chicago borrowings totaled $643.0 million and $652.3 million at March 31, 2015 and December 31, 2014, respectively. The FHLB of Chicago borrowings are also collateralized by mortgage-related securities totaling $70.4 million and $88.9 million at March 31, 2015 and December 31, 2014, respectively. At March 31, 2015, there were no FHLB of Chicago borrowings with call features that may be exercised by the FHLB of Chicago.

	Repurchase Agreements (Securities Sold Under Agreements to Repurchase)

	The Company enters into agreements under which it sells securities subject to an obligation to repurchase the same or similar securities. Under these arrangements, the Company may transfer legal control over the assets but still retain effective control through an agreement that both entitles and obligates the Company to repurchase the assets. As a result, these repurchase agreements are accounted for as collateralized financing arrangements (i.e., secured borrowings) and not as a sale and subsequent repurchase of securities. The obligation to repurchase the securities is reflected as a liability in the Company’s Consolidated Balance Sheet, while the securities underlying the repurchase agreements remain in the respective investment securities asset accounts.

	Long term lease obligation

	The Company enters into agreements from time to time that give the right to use property in exchange for making a series of payments. The terms of the lease obligations typically exceed three years and provide an opportunity to purchase the leased item at the end of the lease term at a price below market rate. These types of leases are considered a capital lease because the Company has in essence accepted the risks and benefits of ownership. As a result a capital lease requires an asset that must be subsequently depreciated and included as property and equipment on the balance sheet.

Regulatory_Capital

Regulatory Capital	3 Months Ended
Regulatory Capital	Mar. 31, 2015
Banking and Thrift [Abstract]
Regulatory Capital	Note 10 – Regulatory Capital
	In July 2013, the federal banking agencies published final rules (the “Basel III Capital Rules”) that revised their risk-based and leverage capital requirements and their method for calculating risk-weighted assets to implement, in part, agreements reached by the Basel Committee and certain provisions of the Dodd-Frank Act. The Basel III Capital Rules apply to banking organizations, including the Company and the Bank.

	In connection with the effectiveness of BASEL III, most banks are required to decide whether to elect to opt-out of the inclusion of Accumulated Other Comprehensive Income (“AOCI”) in their Common Equity Tier 1 Capital. This is a one-time election and generally irrevocable. If electing to opt-out, most AOCI items will not be included in the calculation of Common Equity Tier 1 Capital. In other words, most AOCI items will be treated, for regulatory capital purposes, in the same manner in which they were prior to BASEL III. AnchorBank has elected to opt-out of the inclusion.
	Among other things, the Basel III Capital Rules: (i) introduce a new capital measure entitled “Common Equity Tier 1” (“CET1”); (ii) specify that tier 1 capital consist of CET1 and additional financial instruments satisfying specified requirements that permit inclusion in tier 1 capital; (iii) define CET1 narrowly by requiring that most deductions or adjustments to regulatory capital measures be made to CET1 and not to the other components of capital; and (iv) expand the scope of the deductions or adjustments from capital as compared to the existing regulations.
	A minimum leverage ratio (tier 1 capital as a percentage of total assets) of 4.0% is also required under the Basel III Capital Rules (even for highly rated institutions). The Basel III Capital Rules additionally require institutions to retain a capital conservation buffer of 2.5% above these required minimum capital ratio levels. Banking organizations that fail to maintain the minimum 2.5% capital conservation buffer could face restrictions on capital distributions or discretionary bonus payments to executive officers.
	The Basel III Capital Rules became effective as applied to the Company and the Bank on January 1, 2015, with a phase in period that generally extends from January 1, 2015 through January 1, 2019.
	The Company and Bank are 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 consolidated 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 Company and Bank to maintain minimum amounts and ratios of Common Tier 1 Capital (“CET1”), Tier 1 Capital, Total Capital and leverage ratio of Tier 1 Capital. As of January 1, 2015 the requirements are:
		•		4.5% based upon CET1
		•		6.0% based upon tier 1 capital
		•		8.0% based on total regulatory capital
		•		Leverage ratio of Tier 1 Capital assets equal to 4%

	The following table summarizes the Company’s and Bank capital ratios:

			March 31, 2015						December 31, 2014

	Prior to January 1, 2015, ABCW as a Savings & Loan Holding Company (“SLHC”) was not subject to calculating regulatory capital ratios, as required under Basel III. For December 31, 2014, regulatory capital ratios were calculated under Basel I rules. See the Company’s annual report on Form 10-K for the year ended December 31, 2014 for further discussion of Basel I and Basel III.

	Defined Contribution Plan

	The Company maintains a defined contribution plan under Sections 401(a) and 401(k) of the Internal Revenue Code, the AnchorBank, fsb Retirement Plan, in which all employees are eligible to participate. Employees become eligible on the first of the month following 60 days of employment. Participating employees may contribute up to 100% of their base compensation on a pre-tax basis up to annual internal revenue service limits. The company matches the first 2% contributed with a dollar-for-dollar match, the next 2% is matched at a rate of $0.50 for each dollar and the next 4% is matched at $0.25 for each dollar. The plan offers 14 investment choices in addition to 5 model portfolios. Employees are allowed to self-direct their investments on a daily basis. The Company may also contribute additional amounts at its discretion. The Company contributed $329,000 and $235,000 for the three month period ending March 31, 2015 and 2014, respectively.



	Omnibus Incentive Plan

	On August 12, 2014, the Board of Directors (“Board”) of the Company approved a new incentive plan, the Anchor BanCorp Wisconsin Inc. 2014 Omnibus Incentive Plan (the“Omnibus Plan”) which was subsequently approved by stockholders. The Omnibus Plan provides for the issuance of awards of incentive or nonqualified stock options, stock appreciation rights, performance and restricted stock awards or units, dividend equivalent units and other stock based awards as determined by the Board or the Plan Administrator. The purpose of the Omnibus Plan is to promote the interest of the Company and its stockholders by attracting, retaining and motivating executives and other selected employees, directors, consultants and advisors by enabling such individuals to participate in the long-term growth and financial success of the Company.

	The maximum number of shares of common stock (each, a “share”) that may be issued to participants pursuant to awards under the Omnibus Plan will be equal to 600,000. Such shares may be either authorized and unissued shares or shares reacquired at any time and now or hereafter held as treasury stock. At March 31, 2015, 342,953 shares were available to grant pursuant to the Omnibus Plan.

	Restricted stock grants vest over various periods of time typically from one to three years and are included in outstanding shares at the time of grant. The fair value of restricted stock grants determined at the grant date is amortized to compensation and benefits expense over the vesting period. The restricted stock grant plan expense for the three months ending March 31, 2015 was $590,000. Dividends, if declared, will accrue for the benefit of the individuals who are granted restricted stock and will be paid out as the stock vests. Unvested shares will be voted by the employees in the same manner as the vested shares.

	The restricted stock activity is summarized as follows:



		Shares			Weighted

	Shares available to grant as of March 31, 2015		342,953

	During the three month period ending March 31, 2015, 7,176 shares of the Company’s common stock was surrendered under this plan to satisfy the withholding taxes due upon the vesting of certain previously awarded shares. As of March 31, 2015 and December 31, 2014, respectively, there was approximately $4.8 million and $3.1 million of unrecognized compensation expense related to nonvested restricted stock awards granted under the Plan. The remaining weighted average term of nonvested awards is 1.6 years.

	Accounting Standards Codification (“ASC”) 210-20-50 requires entities to provide disclosures of both gross information and net information about instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. The objective of this disclosure is to facilitate comparison between those entities that prepare their financial statements on the basis of GAAP and those entities that prepare their financial statements on the basis of International Financial Reporting Standards, (“IFRS”).

	Offsetting, otherwise known as netting, takes place when entities present their rights and obligations to each other as a net amount in their statement of financial condition. The Company has certain assets and liabilities on the Consolidated Balance Sheets which could be subject to the right of setoff and related arrangements associated with financial instruments and derivatives. Derivative instruments reported are used as part of a risk management strategy to address exposure to changes in interest rates inherent in the Company’s origination and sale of certain residential mortgages into the secondary market, as presented in Note 14 – Derivative Financial Instruments. In addition, the Company enters into interest rate-related instruments to facilitate the interest rate risk management strategies of commercial customers. The interest agreements are derivatives and are recorded at fair value in the Company’s consolidated balance sheet. A repurchase agreement is a transaction that involves the “sale” of financial assets by one party to another, subject to an agreement by the “seller” to repurchase the assets at a specified date or in specified circumstances.

	The following table reflects the gross and net amounts of such assets and liabilities as of March 31, 2015 and December 31, 2014.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Note 13 – Commitments and Contingent Liabilities

	The Company 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 Company 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.



	Financial instruments whose contract amounts represent credit risk are as follows:



		March 31, 2015			December 31, 2014
		(In thousands)
	Commitments to extend credit	$	64,697		$	39,251
	Unused commitments		—			—
	Unused lines of credit:
	Home equity		111,335			111,365
	Credit cards		—			23,249
	Commercial		137,467			144,333
	Letters of credit		8,503			8,564
	Credit enhancement under the Federal Home Loan Bank of Chicago Mortgage Partnership Finance Program		7,641			7,644

	Commitments to extend credit are in the form of a loan in the near future. 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 Company 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 Company evaluates each customer’s creditworthiness on a case-by-case basis. With the exception of credit card lines of credit, the Company primarily extends credit on a secured basis. Collateral obtained consists primarily of single-family residences andincome-producing commercial properties.

	The Bank previously participated in the Mortgage Partnership Finance Program of the FHLB of Chicago (“MPF Program”). Pursuant to the credit enhancement feature of the MPF Program, the Bank retained a secondary credit loss exposure in the amount of $7.6 million at March 31, 2015 related to approximately $155.0 million of residential mortgage loans that the Bank has originated and are still outstanding. The Bank acts as a servicing agent for the FHLB of Chicago. Under the credit enhancement, the FHLB of Chicago is liable for losses on loans up to one percent of the original delivered loan balances in each pool up to the point the credit enhancement is reset. After the credit enhancement resets, the FHLB of Chicago and the Bank’s loss contingency could be reduced depending upon losses experienced and loan balances remaining. The Bank is liable for losses over and above the FHLB of Chicago first loss position up to a contractually agreed-upon maximum amount in each pool that was delivered to the MPF Program. The Bank receives a monthly fee for this credit enhancement obligation based on the outstanding loan balances. The monthly fee received is net of losses under the MPF Program. The Bank discontinued funding loans through the MPF Program in 2008.

	Unfunded Commitments and Repurchase Loan Reserve

	In addition to the allowance for loan losses reflected on the Consolidated Balance Sheets, a reserve is also provided for unfunded loan commitments and for the repurchase of previously sold loans. The reserve for unfunded loan commitments includes unfunded commitments to lend and commercial letters of credit. These reserves are classified in other liabilities on the Consolidated Balance Sheets.



	The balances of these reserves for the periods presented is as follows:



		Three months ended March 31,
		2015			2014
		(In thousands)
	Reserve for unfunded commitment losses beginning balance	$	2,557		$	4,664
	Provision for unfunded commitments		121			180

	Ending reserve for unfunded commitment losses	$	2,678		$	4,844

	Reserve for repurchased loans beginning balance	$	1,338		$	2,600
	Charge off		(153	)		—
	Recovery		63			—
	Provision for repurchased loans		(100	)		—

	Ending reserve for repurchased loans	$	1,148		$	2,600


	The amount of the allowance for unfunded loan commitments is determined using the average reserve rate by risk rating that applies to the associated funded loan category multiplied by the unfunded commitment amount. The reserve also covers potential loss on letters of credit outstanding for which the Bank may be unable to recover the amount outstanding. At March 31, 2015, a liability of $2.7 million was required as compared to a liability of $4.8 million at March 31, 2014.

	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 any of these representations and warranties or standards are found to be out of compliance, the Company may be responsible for repurchasing the loan at the unpaid principal balance or indemnifying the buyer against loss related to that loan.

	If it is determined at a later date, that a loan did not meet these requirements or was a fraudulent transaction, the investor may require the Bank to either repurchase the loan or make the investor whole in the event of a loss. The unpaid principal balance of loans repurchased from investors totaled $689,000 and $180,000 for the three months ended March 31, 2015 and 2014, respectively. Alternatively, investors make requests to be made whole on a loan whereby the property has been disposed of at a loss. The related amounts for requests by the investor to be made whole was $125,000 and $162,000 for the three months ended March 31, 2015 and 2014, respectively. All losses incurred are recorded against the reserve for repurchased loans on the Consolidated Balance Sheets.

	The amount of the reserve for repurchased loans is determined using the serviced portfolio balances multiplied by historical and expected loss rates to provide for the probable losses related to sold mortgage loans. The reserve declined $190,000 during the three months ended March 31, 2015 compared to remaining unchanged during the prior year period. Investor loss reimbursement expense recorded a reserve release of $100,000 for the three months ended March 31, 2015. Total expense incurred for investor loss reimbursements, including any provision recorded or reserve released, was $162,000 for the three months ended March 31, 2014. Losses, as previously stated, may result from the repurchase of loans or indemnification of losses incurred upon foreclosure and disposition of related collateral. The analysis of the reserve at March 31, 2015 required a liability of $1.1 million.

	In the ordinary course of business, there are legal proceedings against the Company 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 Company.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Note 14 – Derivative Financial Instruments

	The Company 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 Company’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; (2) forward sale contracts for the future delivery of funded residential mortgages; and (3) interest swap products offered directly.

	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 Income.

	The Company has developed a program to enter into interest rate swap arrangements to manage the interest rate risk exposure associated with specific commercial loan relationships at the time such loans are originated. These interest rate swaps, as well as the embedded derivatives associated with certain of its commercial loan relationships, are derivative financial instruments under GAAP. None of these derivative financial instruments would be designated by the Company as accounting hedges as specified in GAAP. As such, the fair market value of the interest rate swaps and embedded derivatives will be carried on the Company’s balance sheet as derivative assets or liabilities, as the case may be, and periodic changes in fair market value of such financial instruments will be recorded through periodic earnings in other non-interest income. At March 31, 2015 the aggregate notional value of interest rate swaps with various commercial customers was $15.7 million.

	Derivative financial instruments are summarized as follows:

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Note 15 - 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

An independent service is used to price available-for-sale U.S. government sponsored and federal agency obligations, government sponsored agency mortgage-backed securities, and GNMA mortgage-backed securities using a market data model under Level 2. The significant inputs used to price GNMA mortgage-backed securities are as follows:



								Weighted									Weighted

As of March 31, 2015 one non-agency CMO was paid off by the issuing agency, which represented 6.6% of the Company’s non-agency CMO’s. The remaining CMO is not validated by an independent pricing service.

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 Company 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 Company 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 Company 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.



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 March 31, 2015 and December 31, 2014.

The carrying amount and fair value of existing derivative financial instruments are based upon independent valuation models, which use widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative contract. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities and have been categorized as Level 2.

There were no transfers out of Level 3 to Level 2 for the three months ended March 31, 2015 and 2014, respectively. The Company’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). 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:



		Level 1			Level 2			Level 3			Total
		(In thousands)

Impaired loans, with an allowance recorded, net		$	—		$	—		$	25,583		$	25,583

Other real estate owned			—			—			35,491			35,491

Total assets at fair value		$	—		$	—		$	86,740		$	86,740




The significant inputs for those assets measured at fair value on a nonrecurring basis are as follows:



		March 31, 2015
		Method		Inputs
Impaired loans, with an allowance recorded, net		Appraised Values		External appraised values - adjustments made to values due to management factors including age of appraisal, age of comparables, known changes in the market and in the collateral and selling and commission cost of 15 % to 35%.

Mortgage servicing rights		Discounted Cash Flow		Weighted average prepayment speed 10.26%; weighted average discount rate 11.44%.

Other real estate owned		Appraised Values		External appraised values less selling and commission cost of 15 % to 35%.

The Company 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.

MSRs 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. Mortgage servicing rights are valued monthly by an independent third party valuation service with income adjustments recorded monthly. On an annual basis the valuation is validated by a separate third party valuation service. 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. 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 11.0% to 24.5% as well as portfolio weighted average prepayment speeds of 4.1% to 42.1% annual Conditional Prepayment Rate (“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 subject to discounting 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 all non-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 Company.

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 held for investment, net: 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 of checking, savings and money market accounts are reported at book value, which is the amount payable on demand. The fair values of fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies current interest rates being offered on certificates of deposit to a schedule of aggregated expected monthly maturities of the outstanding certificates of deposit. 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 and repurchase agreements are estimated using discounted cash flow analysis, based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements. The fair value of the long-term lease obligation is reported at book value, which represents the present value of the cash flows at the time of inception and is indicative of the fair value in the current stable rate environment. In accordance with ASC Topic 820, other borrowed funds have been categorized as a Level 2 fair value measurement.

	At March 31, 2015 and December 31, 2014, the Company 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 years caused by the significant loss provisions associated with the loan portfolio. Therefore, a valuation allowance of $109.5 million and $113.1 million at March 31, 2015 and December 31, 2014, respectively, was recorded to offset net deferred tax assets.

	At March 31, 2015 and December 31, 2014, the affiliated group had a federal net operating loss and tax credit carryover of $200.3 million and $200.6 million, respectively, and at March 31, 2015 and December 31, 2014, certain subsidiaries had state net operating loss carryovers of $317.5 million and $320.1 million, respectively. These carryovers expire in varying amounts in 2015 through 2034.

Earnings Per Share	Note 17 – Earnings Per Share

	Basic earnings per share for the three months ended March 31, 2015 and 2014 have been determined by dividing net income for the respective periods by the weighted average number of shares of common stock outstanding. Unvested shares of restricted stock are not considered outstanding for purposes of basic earnings per share. Diluted earnings per share is computed by dividing net income by the weighted average number of common shares outstanding plus the effect of dilutive securities. The effects of dilutive securities, if any, are computed using the treasury stock method.

	On April 9, 2015 the Company announced several actions to address and improve the Company’s overall operational efficiency and performance.

	The Bank announced the sale of its Winneconne, Wisconsin branch to another bank located in Wisconsin. The purchasing bank will assume approximately $13.4 million in deposits along with loans and other assets. The transaction is subject to regulatory approval and customary closing conditions and is targeted to close by the end of August, 2015.

	In addition, the Bank will offer a Voluntary Separation Plan to eligible employees providing a variety of benefits, including additional compensation, subsidized COBRA health benefits and optional job placement services. The program has been offered to 140 of the Bank’s current 705 employees.

	Also, in an effort to streamline branch operations and further reduce expenses, the Bank will consolidate six retail bank branches. The six locations are in the Wisconsin communities of Appleton, Menasha, Oshkosh, Janesville, Franklin and Madison. A total of 30 full and part-time positions will be eliminated through the six branch consolidations with those employees having priority placement for open AnchorBank positions and also being provided outplacement services to help ensure a smooth and successful career transition. The closures are expected to be completed in the third quarter of 2015. Customers were notified of the upcoming transition and will continue to be provided products and services through our other locations, as well as internet, mobile banking and telephone banking channels. The Bank anticipates it will retain the majority of deposits and loans currently serviced through these locations although there can be no assurances. In connection with the closures, the Bank intends to dispose of the related properties and select equipment. Of the affected branches, 4 are owned and 2 are leased.

	The Bank announced the creation of a new Universal Banker staffing model in branches where we experience lower transaction volumes. The move will allow the majority of employees to perform most branch transactions for customers with the approach providing our customers with the best customer service possible while simultaneously improving branch efficiencies.

	As a result of these operational efficiency measures, the Bank anticipates taking one-time costs in the second quarter of 2015 related to asset disposition costs, employment-related costs and other expenses.

	The unaudited consolidated financial statements include the accounts and results of operations of Anchor BanCorp Wisconsin Inc. (the “Company”, “we”, “our”) and its wholly-owned subsidiaries, AnchorBank, fsb (the “Bank”) and Investment Directions, Inc. (“IDI”). The Bank has one subsidiary: 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 under the Securities Exchange Act of 1934, as amended. 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 consolidated 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 fair value of investment securities, 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. The results of operations and other data for the three month period ended March 31, 2015 are not necessarily indicative of results that may be expected for the year ending December 31, 2015. We have evaluated all subsequent events through the date of this filing. See Note 18-Subsequent Events to the Unaudited Consolidated Financial Statements. 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 Company’s Annual Report on Form 10-K for the year ended December 31, 2014.

Recent Accounting Pronouncements	Accounting Standards Update, (“ASU”), No. 2015-03 “Interest-Imputation of Interest (Subtopic 835-30).” ASU 2015-03 simplifies the presentation of debt issuance costs, requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. This amendment is effective for fiscal years beginning after December 15, 2015 and interim periods within those fiscal years. Early adoption is permitted for financial statements that have not been previously issued. Entities should apply the new guidance on a retrospective basis, wherein the balance sheet of each individual period presented should be adjusted to reflect the period-specific effects of applying the new guidance. The Company intends to adopt the accounting standard during the first quarter of 2016, as required, with no material impact.

	ASU, No. 2015-02 “Consolidation (Topic 810).” ASU 2015-02 is an amendment to the consolidation process and addresses the current accounting for consolidation of certain legal entities. All legal entities are subject to reevaluation under the revised consolidation model. The new standard reduces the number of consolidation models from four to two, simplifying consolidation by placing more emphasis on risk of loss when determining a controlling financial interest, reducing the frequency of the application of related-party guidance when determining a controlling financial interest in a variable interest entity and changing consolidation conclusions in several industries that typically make use of limited partnerships or VIEs. This amendment is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. Entities may apply the amendment prospectively or retrospectively to all prior periods presented in the financial statements. Early adoption is permitted provided that the guidance is applied from the beginning of the year of adoption. The Company intends to adopt the accounting standard during the first quarter of 2016, as required, with no material impact.

	ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606).” In May 2014, the Financial Accounting Standards Board (“FASB”) issued an amendment to clarify the principles for recognizing revenue and to develop a common revenue standard. The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that “an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” In applying the revenue model to contracts within its scope, an entity should apply the following steps: (1) Identify the contract(s) with a customer, (2) Identify the performance obligations in the contract, (3) Determine the transaction price, (4) Allocate the transaction price to the performance obligations in the contract, and (5) Recognize revenue when (or as) the entity satisfies a performance obligation. The standard applies to all contracts with customers except those that are within the scope of other topics in the FASB Codification. The standard also requires significantly expanded disclosures about revenue recognition. The amendment is effective for annual reporting periods beginning after December 15, 2016 (including interim reporting periods within those periods). Early application is not permitted. The Company intends to adopt the accounting standard during the first quarter of 2017, as required, and is currently evaluating the impact on its results of operations, financial position, and liquidity. The FASB on April 1, 2015 agreed to propose a delay of its revenue recognition standard by one year effective for adoption for annual periods beginning after December 15, 2017.
