Nature of Operations and Summary of Significant Accounting Policies	'
	Nature of Operations and Summary of Significant Accounting Policies
	Nature of operations: Westbury Bancorp, Inc. (the Company) is a federal savings and loan holding company headquartered in West Bend, Wisconsin and provides a variety of financial services to individuals and small businesses throughout Southeastern Wisconsin. The Company owns 100% of the stock of Westbury Bank (the Bank). The Bank's primary deposit products are checking, savings and term certificate accounts and its primary lending products are consumer, commercial and residential mortgage loans. The Bank is subject to competition from other financial institutions and non-financial institutions providing financial products. Additionally, the Company and the Bank are subject to the regulations of certain regulatory agencies and undergo periodic examination by those regulatory agencies.
	Organization and principles of consolidation:  The consolidated financial statements include the accounts of the Company and the Bank.  The financial statements of the Bank include the accounts of its wholly-owned subsidiaries, CRH, Inc., a Wisconsin real estate holding company, WBSB Investments, Inc.(WBSBII), a Nevada investment corporation, and Citizens Financial Service Corporation (CFSC). WBSBII and CFSC are no longer active. The financial statements of the Bank also include three wholly-owned limited liability corporations (LLC). These have been formed to own certain of the Bank’s foreclosed properties. All significant intercompany balances and transactions have been eliminated in consolidation.
	Jumpstart Our Business Startups Act: The Jumpstart Our Business Startups Act (the JOBS Act), which was signed into law on April 5, 2012, has made numerous changes to the federal securities laws to facilitate access to capital markets. Under the JOBS Act, a company with total annual gross revenues of less than $1.0 billion during its most recently completed fiscal year qualifies as an “emerging growth company.” The Company qualifies as an “emerging growth company” and believes that it will continue to qualify as an “emerging growth company” until five years from the completion of the stock offering.
	As an “emerging growth company,” the Company has elected to use the extended transition period to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. Accordingly, the financial statements may not be comparable to the financial statements of companies that comply with such new or revised accounting standards.
	Use of estimates: In preparing the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP), management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period. 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, valuation of deferred tax assets and valuation of mortgage servicing rights.
	Changes in fiscal year end: The Company changed its fiscal year end from December 31 to September 30 in 2012. As a result, the attached audited statements of operations, comprehensive income, stockholders' equity and cash flows include results for the year ended September 30, 2013, and the nine months ended September 30, 2012.
	Cash and cash equivalents: For purposes of the consolidated statements of cash flows, cash and cash equivalents includes cash, due from banks, and interest-bearing deposits.
	The Company maintains amounts due from banks that, at times, may exceed federally insured limits. Management monitors these correspondent relationships and has experienced no losses. Accordingly, in the opinion of management, no material risk of loss exists.
	Securities: All securities are classified “available-for-sale” and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in accumulated other comprehensive income, net of the related deferred tax effect.
	Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Declines in the fair value of individual available-for-sale securities below their amortized cost basis that are deemed to be other-than-temporary impairment losses are reflected as realized losses. In determining whether an other-than-temporary impairment exists, management considers many factors including (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 or requirement of the Company to sell its investment in the issuer prior to any anticipated recovery in fair value.
	If the Company intends to sell an impaired security, it records an other-than-temporary loss in an amount equal to the entire difference between the fair value and amortized cost of the security. If a security is determined to be other-than-temporarily impaired, but the Company does not intend to sell the security, only the credit portion of the estimated loss is recognized in earnings, with the other portion of the loss recognized in other comprehensive income. The credit loss component recognized in earnings is identified as the amount of principal cash flows not expected to be received over the remaining term of the security as estimated based on cash flow projections discounted at the applicable original yield of the security.
	Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method.
	Loans held for sale: Loans held for sale are recorded at the lower of cost or fair value as determined on an aggregate basis. Fees received from the borrower and the direct costs of loan originations are deferred and recorded as an adjustment to the sales price, when such loans are sold.
	Loans: The Company grants commercial, mortgage and consumer loans to customers principally located in Southeastern Wisconsin. The ability of the Company’s loan customers to meet the terms of their loans is dependent upon the general economic conditions in this area and real estate values.
	Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are generally reported at their outstanding unpaid principal balances adjusted for charge-offs, the allowance for loan losses, and deferred loan fees or costs on an originated basis. Interest income is accrued on the unpaid principal balance. Loan origination and commitment fees and certain direct loan origination costs on loans receivable are deferred, and the net amounts amortized as an adjustment of the related loan’s yield. These amounts are amortized, using the level-yield method, over the contractual life of the related loans. Unamortized deferred amounts are included in interest income upon repayment or sale of the related loan.
	The accrual of interest on loans is discontinued at the time the loan is ninety days delinquent, unless the loan is well-secured and in the process of collection. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not collected for loans that are placed on nonaccrual status or charged-off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
	Allowance for loan losses: For all portfolio segments, the allowance for loan losses is maintained at the level considered adequate by management of the Company to provide for losses that are probable. The allowance is increased by provisions charged to operating expense and reduced by net charge-offs. In determining the adequacy of the allowance balance, the Company makes continuous evaluations of the loan portfolio and related off-balance sheet commitments, considers current economic conditions and historical loss experience, and reviews specific problem loans and other factors.
	When establishing the allowance for loan losses, management categorizes loans into risk categories generally based on the nature of the collateral and the basis of repayment. These risk categories and their relevant risk characteristics are as follows:
	Single family: Single family loans are real estate loans generally smaller in size and are homogeneous because they exhibit similar characteristics. Single family loans are underwritten by evaluating the credit history of the borrower, the ability of the borrower to meet the debt service requirements of the loan and total debt obligations, as well as the underlying collateral and the loan to collateral value. Also included in this category are junior liens on 1-4 family residential properties. These loans consist of closed-end loans secured by junior liens on 1-4 family residential properties. Underwriting standards for single family loans are heavily influenced by statutory requirements, which include, but are not limited to, loan-to-value and affordability ratios, risk-based pricing strategies, and documentation requirements.
	Construction and land development: These loans are secured by vacant land and/or property that are in the process of improvement, including (a) land development preparatory to erecting vertical improvements or (b) the on-site construction of industrial, commercial, residential, or farm buildings. Repayment of these loans can be dependent on the sale of the property to third parties or the successful completion of the improvements by the builder for the end user. For purposes of this classification, “construction” includes not only construction of new structures, but any loans originated to finance additions or alterations to existing structures and the demolition of existing structures to make way for new structures. Until a permanent loan originates, or payoff occurs, all construction loans secured by real estate are reported in this loan pool. Loans to finance construction and land development that are not secured by real estate are segmented and reported separate from this pool. In the event a loan is made on property that is not yet improved for the planned development, there is the risk that necessary approvals will not be granted or will be delayed. Construction loans also run the risk that improvements will not be completed on time or in accordance with specifications and projected costs.
	Commercial business: Commercial business loans are extended primarily to middle market customers.  Such credits typically comprise working capital loans, loans for physical asset expansion, asset acquisition loans and other business loans. Loans to closely held businesses will generally be guaranteed in full or for a meaningful amount by the owners of the business. Commercial business loans are made based primarily on the historical and projected cash flow of the borrower and secondarily on the underlying collateral provided by the borrower.  The cash flows of borrowers, however, may not behave as forecasted and collateral securing loans may fluctuate in value due to economic or individual performance factors.  Minimum standards and underwriting guidelines have been established for all commercial and industrial loan types.
	Multifamily: Multifamily loans include loans to finance non-farm properties with five or more units in structures primarily to accommodate households on a temporary or permanent basis. Such credits are typically originated to finance the acquisition of an apartment or condo building/complex. Multifamily loans are made based primarily on the historical and projected cash flow of the subject multifamily property, with assumptions made for vacancy rates. Cash flows and ultimate loan performance rely on the receipt of rental income from the tenants of the property who are themselves subject to fluctuations in national and local economic and unemployment trends.
	Commercial real estate: These loans are primarily secured by office and industrial buildings, warehouses, small retail shopping facilities and various special purpose properties, including hotels and restaurants.  These loans are subject to underwriting standards and processes similar to commercial business loans.  These loans are viewed primarily as cash flow loans and the repayment of these loans is largely dependent on the successful operation of the property.  Loan performance may be adversely affected by factors impacting the general economy or conditions specific to the real estate market such as geographic location and/or property type.
	Consumer and other: These loans may take the form of installment loans, demand loans, or single payment loans, and are extended to individuals for household, family, and other personal expenditures. These include direct consumer automobile loans extended by the Company for the purpose of purchasing a new or used vehicle for personal use. Consumer and installment loans are underwritten by evaluating the credit history of the borrower and the ability of the borrower to meet the debt service requirements of the loan and total debt obligations. Also included in this category are home equity lines of credit. These loans consist of revolving open-end lines of credit secured by 1-4 family residential properties extended to individuals for household, family or other personal expenditures. Underwriting standards for home equity loans are heavily influenced by statutory requirements, which include, but are not limited to, loan-to-value and affordability ratios, risk-based pricing strategies, and documentation requirements.
	The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. In addition, regulatory agencies, as an integral part of their examination processes, periodically review the Company’s allowance for loan losses, and may require the Company to recognize adjustments to its allowance based on their judgments of information available to them at the time of their examinations.
	The allowance consists of specific and general components. The specific component relates to loans that are classified as impaired, and an allowance is established when the collateral value, discounted cash flows or observable market price of the impaired loan are lower than the carrying value of that loan. The general component covers non-impaired loans and is based on the Company’s own loss experience over the most recent two year period, adjusted for qualitative factors. These qualitative factors consider local economic trends, concentrations, management experience and other elements of the Company’s lending operations.
	A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining the impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired.
	Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis by either the fair value of collateral, if the loan is collateral dependent, the present value of expected future cash flows discounted at the loan’s effective interest rate, or the loan’s obtainable market price.
	Single family and consumer and other loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual homogeneous loans for impairment disclosures, unless such loans are the subject of a restructuring agreement due to the financial difficulties of the borrower, the loans are related with another commercial type loan or the loans experience significant payment delinquencies and are not insured.
	Troubled debt restructurings: Loans are accounted for as troubled debt restructurings when a borrower is experiencing financial difficulties that lead to a restructuring of the loan, and the Company grants a “concession” to the borrower that they would not otherwise consider. These concessions include a modification of terms such as a reduction of the stated interest rate or loan balance, a reduction of accrued interest, an extension of the maturity date at an interest rate lower than a current market rate for a new loan with similar risk, or some combination thereof to facilitate repayment.
	Troubled debt restructurings are classified as impaired loans. Payment performance prior and subsequent to the restructuring is taken into account in assessing whether it is likely that the borrower can meet the new terms. A period of sustained repayment, for at least six months, is generally required for return to accrual status. This may result in the loan being returned to accrual at the time of restructuring. A loan that is modified at a market rate of interest will not be classified as a troubled debt restructuring or impaired in the calendar year subsequent to the restructuring if it is in compliance with the modified terms.
	Federal Home Loan Bank stock: Federal Home Loan Bank (FHLB) stock consists of the Company’s required investment in the capital stock of the FHLB. No ready market exists for these securities and they have no quoted market value; as such the stock is carried at cost. Management reviews for impairment based on the ultimate recoverability of the cost basis in the FHLB stock, and no impairment has been identified as a result of these reviews.
	Foreclosed real estate: Real estate acquired by foreclosure or by deed in lieu of foreclosure is initially recorded at fair value less cost to sell at the date of foreclosure, establishing a new cost basis. Costs relating to the development and improvement of property are capitalized; holding costs are charged to expense. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of their carrying amount or fair value less cost to sell. Revenues and expenses from operations and changes in the valuation allowance are included in net expenses from foreclosed real estate.
	Real estate held for investment: Real estate held for investment includes land, rental properties, and certain real estate development projects. Land and real estate development projects are carried at the lower of cost plus capitalized development period interest, or fair value less costs to sell, and are periodically evaluated for impairment. Rental properties are carried at cost less provisions for depreciation computed by the straight-line method over the estimated life of the property. Rental revenue is recognized on a straight-line basis over the term of the lease unless another systemic and rational basis is more representative of the time pattern in which the use benefit is derived from the leased property. The difference between rental income earned on a straight-line basis and the cash rent due under provisions of the lease agreements is recorded as deferred rent receivable and is included as a component of other assets in the accompanying consolidated balance sheets.
	The Company evaluates the carrying value of all real estate held when an indicator of impairment is deemed to exist. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount which the carrying amount of the asset exceeds the fair value of the asset. If the Company intends to dispose of its assets, the assets would be separately presented in the consolidated balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and would no longer be depreciated.
	A property is considered held for sale when a contract for sale is entered into or when management has committed to a plan to sell an asset, the asset is actively marketed, and sale is expected to occur within one year.
	Office properties and equipment: Office properties including equipment are stated at cost less accumulated depreciation, and include expenditures for new facilities and items that substantially increase the useful lives of existing buildings and equipment. Expenditures for normal repairs and maintenance are charged to expense as incurred. When properties are retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the respective accounts and the resulting gain or loss is recorded.
	Mortgage servicing rights: Mortgage servicing rights (MSRs) are initially recognized at fair value when loans have been sold to investors and are amortized over the lives of the loans. Upon sale of loans with servicing retained, the servicing rights are recorded at fair value and remaining proceeds received are allocated to the loan. Amortization of MSRs is based on the ratio of net servicing income received in the current period, to total remaining net servicing income projected to be realized from the MSRs. MSRs are periodically assessed for impairment, which is calculated using estimated net cash flow analysis on a discounted basis. Impairment is recognized in the statement of income, during the period in which it occurs, as an adjustment to the corresponding valuation allowance. For purposes of performing an impairment evaluation, the serviced loan portfolio is stratified on the basis of certain risk characteristics including loan type (i.e., fixed or adjustable interest rates).
	Transfers of financial assets: Transfers of financial assets are accounted for as sales only when the control over the financial assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of the right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets.
	Employee stock ownership plan: The Company has an employee stock ownership plan (ESOP) covering substantially all employees. The cost of shares issued to the ESOP but not yet allocated to participants is presented in the consolidated balance sheets as a reduction of stockholders' equity. Compensation expense is recorded based on the market price of the shares as they are committed to be released for allocation to participant accounts.
	Income taxes: The Company, the Bank, and its subsidiaries file consolidated federal income tax returns and combined state income tax returns. Accordingly, amounts equal to tax benefits of those companies having taxable federal losses or credits are reimbursed by the other companies that incur tax liabilities.
	Deferred income taxes are provided using the liability method whereby deferred tax assets are recognized for deductible temporary differences and operating loss and tax credit carryforwards and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of the changes in tax laws and rates as of the date of enactment.
	The Company accounts for uncertainty in income taxes to determine whether tax benefits claimed or expected to be claimed on a tax return, should be recorded in the consolidated financial statements. The Company may recognize the tax benefit for an uncertain tax position if it is more-likely-than-not that the tax position will be sustained upon examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being utilized upon ultimate settlement.
	It is the Company’s policy that interest and penalties associated with unrecognized tax benefits are classified as additional income taxes in the statement of operations.
	Derivative financial instruments and hedging activities: All derivatives are recognized in the consolidated balance sheets at their fair value. Derivative contracts are maintained related to commitments to fund residential mortgages (interest rate locks) in connection with residential mortgages intended for sale. Such commitments are recorded at fair value in other assets or liabilities, with changes in fair value recorded in net gain or loss on sale of mortgage loans. Fair value is based on fees currently charged to enter into similar agreements, and for fixed rate commitments, also considers the committed rates and current levels of interest rates. Derivative contracts are also maintained related to certificates of deposit, for which changes in the fair value of the derivative are recorded in earnings.
	Comprehensive income: Comprehensive income consists of net income and other comprehensive income. Other comprehensive income includes unrealized gains and losses on securities available-for-sale, which are also recognized as separate components of equity.
	Reclassification: Certain amounts in the 2012 consolidated financial statements have been reclassified to conform to the 2013 presentation. These reclassifications had no effect on net income or loss.
	Segment reporting: The Company views the Bank as one operating segment, therefore, separate reporting of financial segment information is not considered necessary. The Company approaches the Bank and its other subsidiaries as one business enterprise, which operates in a single economic environment, since the products and services, types of customers and regulatory environment all have similar characteristics.
	Recent accounting pronouncements: In April 2011, the FASB issued ASU 2011-02, A Creditor’s Determination of Whether a Restructuring Is a Troubled Debt Restructuring. ASU 2011-02 amends ASC Topic 310, Receivables, by clarifying guidance for creditors in determining whether a concession has been granted and whether a debtor is experiencing financial difficulties. ASU 2011-02 is effective for annual periods ending on or after December 15, 2012 and has been adopted with no impact on the consolidated financial statements and related disclosures.
	In April 2011, the FASB issued ASU 2011-03, Transfers and Servicing (Topic 860) - Reconsideration of Effective Control for Repurchase Agreements. ASU 2011-03 is intended to improve financial reporting of repurchase agreements and other agreements that both entitle and obligate a transferor to repurchase or redeem financial assets before their maturity. ASU 2011-03 removes from the assessments of effective control (i) the criteria requiring the transferor to have the ability to repurchase or redeem the financial asset on substantially the agreed terms, even in the event of default by the transferee, and (ii) the collateral maintenance guidance related to that criterion. ASU 2011-03 was effective for the Company on January 1, 2012 and has been adopted with no impact on the consolidated financial statements and related disclosures.
	In May 2011, the FASB issued ASU 2011-04, Fair Value Measurement (Topic 820) - Amendments to Achieve Common Fair Value Measurements and Disclosure Requirements in U.S. GAAP and IFRS. ASU 2011-04 amends Topic 820, Fair Value Measurements and Disclosures, to converge the fair value measurement guidance U.S. GAAP and International Financial Reporting Standards. ASU 2011-04 clarifies the application of existing fair value measurement requirements, changes certain principles in Topic 820 and requires additional fair value disclosures. ASU 2011-04 is effective for annual periods beginning after December 15, 2011. The guidance primarily impacts fair value disclosures related to Level 3 fair value measurements, and has been adopted with no impact on the consolidated financial statements and related disclosures.
	In June 2011, the FASB issued ASU 2011-05, Comprehensive Income (Topic 220) - Presentation of Comprehensive Income. ASU 2011-05 amends Topic 220, Comprehensive Income, to require that all non-owner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The amendments do not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. Additionally, ASU 2011-05 requires entities to present, on the face of the financial statement, reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement or statements where the components of net income and the components of other comprehensive income are presented. The option to present components of net income and the components of other comprehensive income as part of the statement of changes in stockholders’ equity was eliminated. ASU 2011-05 is effective for fiscal years ending after December 15, 2012 and has been adopted in these consolidated financial statements.
	In February 2013, the FASB issued ASU 2013-02, Comprehensive Income (Topic 220) - Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. ASU 2013-02 amends Topic 220, Comprehensive Income, to require that amounts reclassified out of accumulated other comprehensive income be reported on the appropriate line item of the statement of operations if the amount being reclassified is required by U.S. GAAP to be included in its entirety in net income. ASU 2013-02 is effective for reporting periods beginning after December 31, 2012 and has been adopted in these consolidated financial statements.
	In July 2013, the FASB issued ASU 2013-11, Income Taxes (Topic 740) - Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss or a Tax Credit Carrryforward Exists. ASU 2013-11 is intended to clarify the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss or a tax credit carrryforward exists. This presentation had not been addressed in Topic 740 and there was diversity in reporting practices in those instances. ASU 2013-11 requires an unrecognized tax benefit to be presented as a liability and not netted against a deferred tax asset. ASU 2013-11 is effective for reporting periods beginning after December 15, 2013. Adoption by the Company is not expected to have an impact on the consolidated financial statements and related disclosures.

	Plan of Conversion and Change in Corporate Form
	On September 5, 2012, the Board of Directors of WBSB Bancorp, MHC (“MHC”) adopted a plan of conversion and reorganization (“Plan”). The Plan was approved by the Board of Governors of the Federal Reserve System. The Plan was approved by the affirmative vote of a majority of the total votes eligible to be cast by the voting members of the MHC at a special meeting held on April 1, 2013. The Plan provided for the reorganization of the MHC from a federally chartered mutual holding company into a stock holding company, Westbury Bancorp, Inc. (the “Company”) and an offering by the Company of shares of its common stock to eligible depositors of Westbury Bank (the “Bank”) and the public. The Company is incorporated under the laws of the State of Maryland and owns all of the outstanding common stock of the Bank. The reorganization and conversion was completed with the sale of 5,091,625 shares on April 9, 2013 and shares of the Company began trading on April 10, 2013.
	In addition, in conjunction with the reorganization and conversion in April 2013 the Company contributed a total of $1,000 (consisting of 50,916 shares of common stock and $491 in cash) to a charitable foundation that the Bank has established. The contribution is included in Other expenses in the Consolidated Statements of Operations for the year ended September 30, 2013. The foundation was organized as Westbury Bank Charitable Foundation.
	The costs of reorganization and issuing the common stock have been deducted from the sales proceeds of the offering. The Company recognized $2,574 in reorganization and stock issuance costs as of September 30, 2013.
	In accordance with federal regulations, at the time of the reorganization, the Company substantially restricted retained earnings by establishing a liquidation account and the Bank established a parallel liquidation account. The liquidation account will be maintained for the benefit of eligible account holders who continue to maintain their accounts at the Bank after the reorganization. The liquidation account will be reduced annually to the extent that eligible account holders have reduced their qualifying deposits. Subsequent increases will not restore an eligible account holder’s interest in the liquidation account. In the event of a complete liquidation of the Bank, and only in such event, each eligible account holder will be entitled to receive a distribution from the liquidation account in an amount proportionate to the adjusted qualifying account balances then held. The Bank may not pay dividends if those dividends would reduce equity capital below the required liquidation account amount. The reorganization will be accounted for as a change in corporate form with the historic basis of the Bank’s assets, liabilities and equity unchanged as a result.

	The amortized cost and fair value of securities available-for-sale, by contractual maturity at September 30, 2013, are shown in the following table. Actual maturities differ from contractual maturities for mortgage-backed securities because the mortgages underlying the securities may be called or repaid without penalty. Therefore, these securities are not presented in the maturity categories in the table below.

	Proceeds from sales of securities available-for-sale during the year ended September 30, 2013 and the nine months ended September 30, 2012 were $11,584 and $30,914, respectively. Gross realized gains, during the year ended September 30, 2013 and the nine months ended September 30, 2012, on these sales amounted to $256 and $481, respectively. Gross realized losses on these sales were $24 and $60 during the year ended September 30, 2013 and the nine months ended September 30, 2012, respectively.
	Securities with carrying values of $8,346 and $5,349 at September 30, 2013 and September 30, 2012, respectively, were pledged to secure treasury, tax, and loan deposits and other purposes required or permitted by law.

	At September 30, 2013, the investment portfolio included 13 securities available-for-sale which had been in unrealized loss positions for greater than twelve months and 148 securities which had been in unrealized loss positions for less than twelve months. At September 30, 2012, the investment portfolio did not include any available-for-sale securities which had been in unrealized loss positions for greater than twelve months and included 16 securities which had been in unrealized loss positions for less than twelve months. These securities are considered to be acceptable credit risks. Based upon an evaluation of the available evidence, including recent changes in market rates, credit rating information and information obtained from regulatory filings, management believes the decline in fair value for these securities is temporary. In addition, the Company does not intend to sell these investment securities for a period of time sufficient to allow for anticipated recovery. The Company does not have any current requirement to sell its investment in the issuer prior to any anticipated recovery in fair value.

	As part of the on-going monitoring of the credit quality of the Company’s loan portfolio, management categorizes loans into risk categories based on relevant information about the ability of the borrowers to service their debt and comply with various terms of their loan agreements. The Company considers current financial information, historical payment experience, credit documentation, public information and current economic trends. Generally, all sizeable credits receive a financial review no less than annually to monitor and adjust, if necessary, the credit’s risk profile. Credits classified as watch and special mention generally receive a review more frequently than annually.
The Company categorizes loans into the following risk categories based on relevant information about the ability of borrowers to service their debt:
Pass - A pass asset is well protected by the current worth and paying capacity of the obligor (or guarantors, if any) or by the fair value, less costs to acquire and sell in a timely manner, of any underlying collateral.
Watch - A watch asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Company’s credit position at some future date. Watch assets are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification.
Special Mention - A special mention asset has characteristics of deterioration in quality exhibited by any number of well-defined weaknesses requiring significant corrective action. The repayment ability of the borrower has not been validated, or has become marginal or weak and the loan may have exhibited some overdue payments or payment extensions and/or renewals.
Substandard - A substandard asset is an asset with a well-defined weakness that jeopardizes repayment in whole or in part, of the debt. These credits are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged. These assets are characterized by the distinct possibility that the Company will or has sustained some loss of principal and/or interest if the deficiencies are not corrected.
Doubtful - A doubtful asset is an asset that has all the weaknesses inherent in the substandard classification 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. These credits have a high probability for loss, yet because certain important and reasonably specific pending factors may work toward the strengthening of the asset, its classification of loss is deferred until its more exact status can be determined.
Homogeneous loan types are assessed for credit quality based on the contractual aging status of the loan and payment activity. In certain cases, based upon payment performance, the loan being related with another commercial type loan or for other reasons, a loan may be categorized into one of the risk categories noted above. Such assessment is completed at the end of each reporting period.
The following tables present the risk category of loans evaluated by internal asset classification based on the most recent analysis performed and the contractual aging as of September 30, 2013 and September 30, 2012:

	Advances From the Federal Home Loan Bank
	The Bank maintains a master contract agreement with the Federal Home Loan Bank of Chicago (FHLB) that provides for borrowing up to the maximum of 75 percent of the book value of the Bank’s first lien 1-4 family real estate loans. The FHLB provides both fixed and floating rate advances. Floating rates are tied to short-term market rates of interest, such as LIBOR, Federal Funds or Treasury Bill rates. Fixed rate advances are priced in reference to market rates of interest at the time of the advance, namely the rates that the FHLB pays to borrowers at various maturities. Interest is payable monthly with principal payable at maturity.
	Advances are generally secured by a security agreement pledging a portion of the Bank’s real estate mortgages. Pledged real estate mortgages had a carrying value of $124,693 and $152,752 as of September 30, 2013, and September 30, 2012, respectively.
	The Bank had no advances outstanding from the FHLB at September 30, 2013 or 2012.

	On March 31, 2011, the Company entered into an unsecured note payable with a limited liability company consisting of certain of the Company’s officers and directors that was scheduled to mature March 31, 2014.  The note bore interest at a rate of 9.50 percent and was originated with a balance of $300.  Principal and accrued interest were due in a single payment at the note’s maturity.  Repayment of this note was subordinated to the aforementioned loan agreement.  Proceeds from this new note payable were used to establish an escrow account to fund interest-only payments due under the aforementioned loan agreement through its maturity on March 31, 2014 as the Bank’s primary regulator has curtailed dividends from the Bank to the Company. The note payable was paid in full on April 9, 2013.
	The Company also entered into a note payable with an unaffiliated bank which matured in February 2012.  The note payable bore interest at a rate of 5.25 percent.  The note payable was collateralized by mortgages on income producing real estate properties classified as real estate held for investment.  As of December 31, 2011, the note payable balance was $2,185.

Regulatory Capital Requirements [Abstract]	'
Regulatory Capital	'
	Regulatory Capital
	The Bank is subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary, actions by 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. Prompt corrective action provisions are not applicable to bank holdings companies.
	Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in the table below) of total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and Tier 1 capital (as defined) to average assets (as defined). Management believes, as of September 30, 2013 and September 30, 2012, the Bank meets all capital adequacy requirements to which it is subject.
	In connection with a formal written agreement between the Bank and its primary federal regulator, management instituted a business and capital plan to maintain the stability of the Bank. This business and capital plan requires the Bank to maintain a Tier 1 (leverage) capital ratio of 8.00% and a total risk-based capital ratio of 12.00%. The Bank is in compliance with these capital levels at September 30, 2013. The capital targets prescribed by the business and capital plan have been met through the disposition of problem assets, reduction of non-interest expenses, retention of earnings and completion of a plan of conversion(see Note 2).
	On November 5, 2012, the Bank was notified by its primary regulator that it would be subject to higher minimum capital ratios as of December 31, 2012. The higher minimum capital ratios are identical to the business and capital plan ratios noted above. At September 30, 2013, the Bank was in compliance with those ratios.
	As of September 30, 2013, and September 30, 2012, the Bank was restricted from paying dividends to the Company without the prior consent of their primary regulator. Regardless of formal regulatory restrictions, the Bank would not be allowed to pay dividends in amounts that would result in its capital levels being reduced below the minimum requirements to be adequately capitalized under the regulatory framework for prompt corrective action.
	The Bank’s actual capital amounts and ratios and those required by the above regulatory standards are as follows:

Employee Benefit Plans	'
	Employee Benefit Plans
	Westbury Bank maintains a contributory, defined-contribution profit-sharing plan (the Plan) for all employees meeting certain minimum age and service requirements. The Plan qualifies under Section 401(k) of the Internal Revenue Code. Participants may elect to defer a portion of their compensation (between 2 percent and 10 percent) and contribute this amount to the Plan. A discretionary contribution is made each year as determined annually by the Board of Directors. The contribution is allocated to each participant based on his or her compensation. The aggregate benefit payable to any employee is dependent upon his or her rate of contribution, the earnings of the Plan assets, and the length of time such employee has been a participant in the Plan. The expense related to this Plan was $177 and $234 for the year ended September 30, 2013 and the nine months ended September 30, 2012, respectively.
	Westbury Bank maintains a leveraged employee stock ownership plan (ESOP) that covers all employees meeting certain minimum age and service requirements. The ESOP was established in conjunction with the Company's stock offering completed in April 2013. The loan to fund the acquisition of stock by the ESOP was made by the Company. The Bank makes annual contributions to the ESOP equal to the ESOP's debt service. The ESOP shares initially were pledged as collateral for its debt. As the debt is repaid, shares are released from collateral and allocated to active participants, based on the proportion of debt service paid in the year. The Company accounts for its ESOP in accordance with ASC 718-40. Accordingly, because the debt is intercompany, it is eliminated in consolidation for presentation in these statements. The shares pledged as collateral are reported as unearned ESOP shares in the balance sheet. As shares are committed to be released from collateral, the Company reports compensation expense equal to the current market price of the shares, and the shares become outstanding for EPS computations. During 2013, 13,713 shares, with an average fair value of $13.59 per share, were committed to be released resulting in ESOP compensation expense of $186 for the year ended September 30, 2013. No ESOP compensation expense was recorded for the nine months ended September 30, 2012. The ESOP shares as of September 30 were as follows:

Deferred Compensation	'
	Deferred Compensation
	Certain key employees of Westbury Bank hold nonqualified salary continuation plans. These plans provide for payments of specific amounts over 10 to 20 year periods subsequent to each participant’s retirement. The related deferred compensation liabilities are being accrued ratably to the respective normal retirement dates of each participant. As of September 30, 2013, and September 30, 2012, approximately $1,970 and $2,193 are accrued related to these plans. The expense for compensation under these plans was approximately $176 and $153 for the year ended September 30, 2013 and the nine months ended September 30, 2012, respectively.
	Although not part of the plans, the Company has purchased life insurance on the lives of certain employees electing to participate in the plans, which could provide funding for the payment of benefits. At September 30, 2013, and September 30, 2012, the cash surrender value of such life insurance policies totaled $12,358 and $11,940, respectively.
	The Company currently defers its Directors’ fees at the discretion of the Director, with payments made at the request of each Director. The balances of deferred directors’ fees were $637 and $598 at September 30, 2013, and September 30, 2012, respectively.

Guarantees	'
	Guarantees
	The Bank has executed commitments under the Mortgage Partnership Finance (MPF) program with the FHLB to guarantee the payment of any realized losses that exceed the FHLB’s first loss account for mortgages delivered under the commitments. The Bank receives credit enhancement fees from the FHLB for providing this guarantee and continuing to manage the credit risk of the MPF program mortgage loans. The liability representing the present value of the credit enhancement fees less any expected losses in the mortgages delivered under the commitments was not material. The maximum potential amount of future payments that the Bank could be required to make under the limited recourse guarantee was approximately $347 and $318 at September 30, 2013 and September 30, 2012, respectively. Under the commitments, the Bank agrees to service the loans and therefore, is responsible for any necessary foreclosure proceedings. Any future recoveries on any losses would not be paid by the FHLB under the commitments. Historically, the Bank has not incurred a loss on loans sold to the FHLB with these recourse provisions and management has determined there are no probable losses related to these loans at September 30, 2013, or 2012.

	Net deferred tax asset		$	4,995			$	3,974
	In assessing the reliability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible.
	The Company has State of Wisconsin net operating loss carryforwards of approximately $18,658 and $19,111 at September 30, 2013, and September 30, 2012, respectively, which can be used to offset its future state taxable income. The carryforwards start to expire in 2017. Prior to 2009, each legal entity in the consolidated group filed separately in the State of Wisconsin. A total of $11,013 of the net operating loss carryforward at September 30, 2013 and September 30, 2012, represents the Wisconsin net operating loss from separate company returns (“Separate Return Loss Year” or “SRLY” losses). A valuation allowance of $101 at September 30, 2013, and September 30, 2012, has been established for the future benefits attributed to the SRLY state net operating losses for the two former Holding Company entities for tax years prior to 2009, since it is unlikely that the Holding Company will generate taxable income on a separate basis to utilize these benefits.
	The Company has federal net operating loss carryforwards of approximately $11,175 and $11,552 at September 30, 2013, and September 30, 2012, respectively, which can be used to offset its future federal taxable income. The carryforwards start to expire in 2031. A valuation allowance of $2,447 has been established at September 30, 2013, and September 30, 2012, to reflect management’s evaluation of the Company’s realizability of its net deferred tax assets.
	Under the Internal Revenue Code and Wisconsin Statutes, the Bank is permitted to deduct, for tax years beginning before 1997, an annual addition to a reserve for bad debts. The amount differs from the provision for loan losses recorded for financial accounting purposes. Under prior law, bad debt deductions for income tax purposes were included in taxable income of later years only if the bad debt reserves were used for purposes other than to absorb bad debt losses. Because the Company did not intend to use the reserve for purposes other than to absorb losses, no deferred income taxes were provided. Retained earnings as of September 30, 2013, and September 30, 2012, include approximately $3,227 for which no deferred federal or state income taxes were provided. If in the future the Company no longer qualifies as a bank for tax purposes, an income tax expense of $1,266 would be incurred.
	The Company files income tax returns in the U.S. federal jurisdiction and the state of Wisconsin. With few exceptions, the Company is no longer subject to U.S. federal tax examinations by tax authorities for years before 2009 and state tax examinations by tax authorities for years before 2008.

	Commitments and Contingencies
	Financial Instruments with Off-Balance Sheet Risk
	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 involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets. The contractual amounts of those instruments reflect the extent of involvement the Company has in particular classes of financial instruments.
	The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instruments for commitments to extend credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments.
	The following instruments were outstanding whose contract amounts represent credit risk:
		September 30,		September 30,
		2013		2012
	Commitments to extend mortgage credit:
	Fixed rate	$	372	$	812
	Adjustable rate	971		118
	Unused commercial loan and home equity lines of credit	$	51,755	$	36,553
	Standby letters of credit	140		545
	Commitment to sell loans	1,028		3,022
	Commitments to extend credit are agreements to lend funds to a customer as long as there is no violation of any condition established in the contract. Commitments generally 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. The Company generally extends credit only on a secured basis. Collateral obtained varies but consists primarily of one-to-four family residences.
	Unfunded commitments under lines of credit are commitments for possible future extensions of credit to existing customers. These lines of credit may be uncollateralized and ultimately may not be drawn upon to the total extent to which the Company is committed.
	Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Those letters of credit are primarily issued to support public and private borrowing arrangements, and, generally, have terms of one year or less. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Company holds collateral supporting those commitments if deemed necessary. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Company would be required to fund the commitment. The maximum potential amount of future payments the Company could be required to make is represented by the contractual amount shown in the summary above. If the commitment is funded, the Company would be entitled to seek recovery from the customer. At September 30, 2013, and September 30, 2012, no amounts have been recorded as liabilities for the Company’s potential obligations under these guarantees.
	Litigation
	In the normal course of business, the Company is involved in various legal proceedings. In the opinion of management, any liability resulting from such proceedings would not have a material adverse effect on the Company’s consolidated financial statements.

	Derivative Activities
	The Company invests in, and has on deposit, certain certificates of deposit with embedded derivatives where the related interest income or expense is calculated based on changes in the S&P 500. The Company also enters into interest rate swaps and options to offset the variability in interest income and expense related to these certificates of deposits. At September 30, 2013, and September 30, 2012, the Company had approximately $1,132 and $2,170, respectively, in notional amount of swaps where the Company pays a fixed or LIBOR-based interest rate and receives a variable rate based on the S&P 500. The fair values of the embedded derivatives, swaps and options are reported in the consolidated balance sheets, and the changes in fair value of the embedded derivatives, swaps and options are reported as gains or losses in the consolidated statements of operations. The fair value of the derivative liability was $408 and $513 as of September 30, 2013, and September 30, 2012, respectively, and the related derivative asset was $408 and $513 as of September 30, 2013, and September 30, 2012, respectively. The change in fair value was not significant as of September 30, 2013, and September 30, 2012.
	Commitments to originate residential mortgage loans held for sale and forward commitments to sell residential mortgage loans are defined as derivatives. The fair value related to these commitments was not material as of September 30, 2013, and September 30, 2012.

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	Fair Value Measurements
	ASC Topic 820, Fair Value Measurements and Disclosures, defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. ASC Topic 820 requires the use of valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, meaning those that reflect the reporting entity's own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. In that regard, ASC Topic 820 establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:
	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.
	A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below.
	Securities available-for-sale: The fair value of the Company’s securities available-for-sale is determined using Level 2 inputs, which are derived from readily available pricing sources and third-party pricing services for comparable instruments. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, treasury yield curves, trading levels, credit information and credit terms, among other factors. In certain cases where Level 1 or Level 2 are not available, securities are classified within Level 3 of the hierarchy.
	Derivatives: The fair values of the Company’s embedded derivatives related to certain certificates of deposit are determined using inputs that are observable or that can be corroborated by observable market data (such as the S&P 500 Index and the 10-year U.S. Treasury rate) and, therefore, are classified within Level 2 of the valuation hierarchy.
	Assets and liabilities recorded at fair value on a recurring basis: The following table summarizes assets measured at fair value on a recurring basis, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value as of:
				Fair Value Measurements

	The Company did not have any transfers between Level 1, Level 2, and Level 3 of the fair value hierarchy during the year ended September 30, 2013 and the nine months ended September 30, 2012. The Company’s policy for determining transfers between levels occurs at the end of the reporting period when circumstances in the underlying valuation criteria change and result in a transfer between levels.
	Assets recorded at fair value on a nonrecurring basis: The Company may be required, from time to time, to measure certain instruments at fair value on a nonrecurring basis in accordance with U.S. generally accepted accounting principles.
	Impaired loans: The Company does not record loans at fair value on a recurring basis. The specific reserves for collateral-dependent impaired loans are based on the fair value of the collateral less estimated costs to sell. The fair value of collateral is determined based on appraisals. In some cases, adjustments were made to the 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. When significant adjustments were based on unobservable inputs, the resulting fair value measurement has been categorized as a Level 3 measurement. Impaired loans with a carrying amount of $1,726 and $5,559 have a valuation allowance of $537, and $1,492 included in the allowance for loan losses as of September 30, 2013, and September 30, 2012, respectively.
	Foreclosed real estate:  The Company does not record foreclosed real estate owned at a fair value on a recurring basis.  The fair value of foreclosed real estate was determined using Level 3 inputs based on appraisals or broker pricing opinions.  In some cases, adjustments were made to these values due to various factors including the age of the appraisal, age of comparables included in the appraisal, and known changes in the market and in collateral.  Foreclosed real estate is measured at fair value less estimated costs to sell at the date of foreclosure.  Subsequent to foreclosure, additional writedowns may be recorded based on changes to the fair value of the assets.
	Mortgage servicing rights: Mortgage servicing rights (MSRs) do not trade in an active, open market with readily observable prices. While sales of MSRs do occur, the precise terms and conditions typically are not readily available. Accordingly, the Company estimates the fair value of MSRs using discounted cash flow models incorporating numerous assumptions from the perspective of market participants including servicing income, servicing costs, market discount rates, prepayments speeds, and default rates. Due to the nature of the valuation inputs, MSRs are classified within Level 3 of the valuation hierarchy. As of September 30, 2013, mortgage servicing rights with a carrying amount of $2,152 have a valuation allowance of $321 to reflect their fair value of $1,831. As of September 30, 2012, mortgage servicing rights with a carrying amount of $2,655 have a valuation allowance of $762 to reflect their fair value of $1,893.

	Disclosure of fair value information about financial instruments, for which it is practicable to estimate that value, is required whether or not recognized in the consolidated balance sheets. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those 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, could 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 do not necessarily represent the underlying value of the Company for assets and liabilities not previously described. The Company, in estimating its fair value disclosures for financial instruments not described above, used the following methods and assumptions:
	Cash and cash equivalents: The carrying amounts of cash and cash equivalents reported in the consolidated balance sheets approximate those assets’ fair values.
	Loans: For variable-rate mortgage loans that re-price frequently and with no significant change in credit risk, fair values are based on carrying values. The fair values for fixed rate residential mortgage loans are based on quoted market prices for similar loans sold in conjunction with sale transactions, adjusted for differences in loan characteristics. The fair values for commercial real estate loans, rental property mortgage loans, and consumer and other loans are estimated using discounted cash flow analyses and using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality.
	Loans held for sale: Fair value of loans held for sale are based on commitments on hand from investors or prevailing market prices.
	Federal Home Loan Bank stock: The carrying amount of FHLB stock approximates its fair value based on the redemption provisions of the FHLB.
	Accrued interest receivable and payable: The carrying amounts of accrued interest receivable and payable approximate their fair values.
	Deposits: The fair value disclosed for interest-bearing and non-interest-bearing checking accounts, savings accounts, and money market accounts are equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). The fair values of fixed rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities of the outstanding certificates of deposit.
	Advances from the Federal Home Loan Bank and notes payable: The fair values of FHLB advances and notes payable are estimated using discounted cash flow analyses, based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements.
Advance payments by borrowers for property taxes and insurance: The carrying amounts of the advance payments by borrowers for property taxes and insurance approximate their fair values.
Mortgage banking derivatives: The fair value of commitments to originate mortgage loans held for sale is estimated by comparing the Company’s cost to acquire mortgages and the current price for similar mortgage loans, taking into account the terms of the commitments and the credit worthiness of the counterparties. The fair value of forward commitments to sell residential mortgage loans is the estimated amount that the Bank would receive or pay to terminate the forward delivery contract at the reporting date based on market prices for similar financial instruments. The fair value of these derivative financial instruments was not material at September 30, 2013, or 2012.
The estimated fair values and related carrying amounts of the Company’s financial instruments are as follows:

Regulatory Actions and Management's Plans	'
	Regulatory Actions and Management’s Plans
	In October 2012, the Bank entered into a Formal Agreement with the OCC (the Formal Agreement), which superseded and replaced a prior agreement with the Office of Thrift Supervision. Pursuant to the Formal Agreement, the Bank agreed, among other things, to:
	•	submit a business and capital plan that provides for plans and strategies including (i) specific plans for the maintenance of adequate capital given the Bank’s risk profile, (ii) projections for growth and capital requirements based upon a detailed analysis of the Bank’s assets, liabilities, earnings, fixed assets and off-balance sheet activities, (iii) projections of the sources and timing of additional capital to meet the Bank’s current and future needs, and (iv) the primary sources from which the Bank will strengthen its capital structure to meet its needs and contingency plans that identify alternative methods should the primary sources not be available;
	•	adopt a written program to improve the Bank’s credit administration practices, including policies, procedures and controls as necessary to ensure (i) timely and accurate credit risk ratings based on regulatory definitions of “special mention,” “substandard,” “doubtful,” and “loss,” (ii) compliance of the Bank’s appraisal and evaluation program with applicable regulations and guidance, (iii) timely and effective follow-up and implementation of loan review findings and exceptions, (iv) satisfactory and perfected collateral documentation, (v) that extensions of credit are granted to any borrower only after obtaining and analyzing current and satisfactory credit information and performing and documenting analysis of the borrower’s financial position and repayment sources, (vi) timely loan charge-offs and accurate reporting of troubled debt restructurings, (vii) annual credit reviews, (viii) conformance with loan policy requirements, (ix) adequate systems to track and analyze credit and collateral exceptions, (x) the accuracy and integrity of internal management information and loan filing systems, and (xi) systems to track and analyze concentrations of credit, significant economic factors, and general conditions and their potential impact on the credit quality of the Bank’s loan and lease portfolios;
	•	revise its written policies and procedures for maintaining an adequate allowance for loan and lease losses to include, at a minimum, (i) policies and procedures for determining whether a loan is impaired and measuring the amount of impairment consistent with GAAP, (ii) policies and procedures for segmenting the loan portfolio and estimating loss on groups of loans that are consistent with GAAP and requiring the documentation of support for its estimation of credit losses, and (iii) procedures for validating the Bank’s allowance for loan and lease losses methodology;
	•	appoint, if the position of Chief Credit Officer becomes vacant, a capable person with executive authority to ensure compliance with the Formal Agreement and the safe and sound operation of functions within that position’s responsibility, which appointment shall be subject to the review and notice or disapproval of the OCC;
	•	not declare any dividend or capital distribution unless the Bank (i) is in compliance with its approved capital program, (ii) is in compliance with applicable regulations governing dividends and capital distributions, and (iii) has received the prior written non-objection of the OCC;
	•	take immediate and continuing action to protect its interest in all criticized assets, including adopting individual workout plans for criticized assets that equal or exceed $500,000, and reviewing to resolve the basis of criticism of all classified, special mention and delinquent assets or credit relationships that equal or exceed $500,000;
	•	not extend any additional credit to or for the benefit of any borrower who has a loan or other extension of credit that is criticized and whose aggregate loans or other extensions of credit exceed $250,000 only if (i) the Board of Directors determines that the extension of additional credit is necessary to promote the best interests of the Bank and records in writing its reasons for this determination, and (ii) a comparison to the Bank’s written program with respect to that asset shows that such plan to collect or strengthen the criticized asset will not be compromised; and
	•	appoint a Compliance Committee that will be responsible for monitoring and coordinating the Bank’s adherence to the provisions of the Formal Agreement and reporting regularly to the OCC.

Nature of Operations and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Sep. 30, 2013
Organization, Consolidation and Presentation of Financial Statements [Abstract]	'
Organization and principles of consolidation	'
	Organization and principles of consolidation:  The consolidated financial statements include the accounts of the Company and the Bank.  The financial statements of the Bank include the accounts of its wholly-owned subsidiaries, CRH, Inc., a Wisconsin real estate holding company, WBSB Investments, Inc.(WBSBII), a Nevada investment corporation, and Citizens Financial Service Corporation (CFSC). WBSBII and CFSC are no longer active. The financial statements of the Bank also include three wholly-owned limited liability corporations (LLC). These have been formed to own certain of the Bank’s foreclosed properties. All significant intercompany balances and transactions have been eliminated in consolidation.
Jumpstart Our Business Startups Act	'
	Jumpstart Our Business Startups Act: The Jumpstart Our Business Startups Act (the JOBS Act), which was signed into law on April 5, 2012, has made numerous changes to the federal securities laws to facilitate access to capital markets. Under the JOBS Act, a company with total annual gross revenues of less than $1.0 billion during its most recently completed fiscal year qualifies as an “emerging growth company.” The Company qualifies as an “emerging growth company” and believes that it will continue to qualify as an “emerging growth company” until five years from the completion of the stock offering.
	As an “emerging growth company,” the Company has elected to use the extended transition period to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. Accordingly, the financial statements may not be comparable to the financial statements of companies that comply with such new or revised accounting standards.
Use of estimates	'
	Use of estimates: In preparing the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP), management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period. 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, valuation of deferred tax assets and valuation of mortgage servicing rights.
Changes in fiscal year end	'
	Changes in fiscal year end: The Company changed its fiscal year end from December 31 to September 30 in 2012. As a result, the attached audited statements of operations, comprehensive income, stockholders' equity and cash flows include results for the year ended September 30, 2013, and the nine months ended September 30, 2012.
Cash and cash equivalents	'
	Cash and cash equivalents: For purposes of the consolidated statements of cash flows, cash and cash equivalents includes cash, due from banks, and interest-bearing deposits.
	The Company maintains amounts due from banks that, at times, may exceed federally insured limits. Management monitors these correspondent relationships and has experienced no losses. Accordingly, in the opinion of management, no material risk of loss exists.
Securities	'
	Securities: All securities are classified “available-for-sale” and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in accumulated other comprehensive income, net of the related deferred tax effect.
	Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Declines in the fair value of individual available-for-sale securities below their amortized cost basis that are deemed to be other-than-temporary impairment losses are reflected as realized losses. In determining whether an other-than-temporary impairment exists, management considers many factors including (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 or requirement of the Company to sell its investment in the issuer prior to any anticipated recovery in fair value.
	If the Company intends to sell an impaired security, it records an other-than-temporary loss in an amount equal to the entire difference between the fair value and amortized cost of the security. If a security is determined to be other-than-temporarily impaired, but the Company does not intend to sell the security, only the credit portion of the estimated loss is recognized in earnings, with the other portion of the loss recognized in other comprehensive income. The credit loss component recognized in earnings is identified as the amount of principal cash flows not expected to be received over the remaining term of the security as estimated based on cash flow projections discounted at the applicable original yield of the security.
	Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method.
Loans held for sale	'
	Loans held for sale: Loans held for sale are recorded at the lower of cost or fair value as determined on an aggregate basis. Fees received from the borrower and the direct costs of loan originations are deferred and recorded as an adjustment to the sales price, when such loans are sold.
Loans	'
	Loans: The Company grants commercial, mortgage and consumer loans to customers principally located in Southeastern Wisconsin. The ability of the Company’s loan customers to meet the terms of their loans is dependent upon the general economic conditions in this area and real estate values.
	Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are generally reported at their outstanding unpaid principal balances adjusted for charge-offs, the allowance for loan losses, and deferred loan fees or costs on an originated basis. Interest income is accrued on the unpaid principal balance. Loan origination and commitment fees and certain direct loan origination costs on loans receivable are deferred, and the net amounts amortized as an adjustment of the related loan’s yield. These amounts are amortized, using the level-yield method, over the contractual life of the related loans. Unamortized deferred amounts are included in interest income upon repayment or sale of the related loan.
	The accrual of interest on loans is discontinued at the time the loan is ninety days delinquent, unless the loan is well-secured and in the process of collection. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not collected for loans that are placed on nonaccrual status or charged-off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Allowance for loan losses	'
	Allowance for loan losses: For all portfolio segments, the allowance for loan losses is maintained at the level considered adequate by management of the Company to provide for losses that are probable. The allowance is increased by provisions charged to operating expense and reduced by net charge-offs. In determining the adequacy of the allowance balance, the Company makes continuous evaluations of the loan portfolio and related off-balance sheet commitments, considers current economic conditions and historical loss experience, and reviews specific problem loans and other factors.
	When establishing the allowance for loan losses, management categorizes loans into risk categories generally based on the nature of the collateral and the basis of repayment. These risk categories and their relevant risk characteristics are as follows:
	Single family: Single family loans are real estate loans generally smaller in size and are homogeneous because they exhibit similar characteristics. Single family loans are underwritten by evaluating the credit history of the borrower, the ability of the borrower to meet the debt service requirements of the loan and total debt obligations, as well as the underlying collateral and the loan to collateral value. Also included in this category are junior liens on 1-4 family residential properties. These loans consist of closed-end loans secured by junior liens on 1-4 family residential properties. Underwriting standards for single family loans are heavily influenced by statutory requirements, which include, but are not limited to, loan-to-value and affordability ratios, risk-based pricing strategies, and documentation requirements.
	Construction and land development: These loans are secured by vacant land and/or property that are in the process of improvement, including (a) land development preparatory to erecting vertical improvements or (b) the on-site construction of industrial, commercial, residential, or farm buildings. Repayment of these loans can be dependent on the sale of the property to third parties or the successful completion of the improvements by the builder for the end user. For purposes of this classification, “construction” includes not only construction of new structures, but any loans originated to finance additions or alterations to existing structures and the demolition of existing structures to make way for new structures. Until a permanent loan originates, or payoff occurs, all construction loans secured by real estate are reported in this loan pool. Loans to finance construction and land development that are not secured by real estate are segmented and reported separate from this pool. In the event a loan is made on property that is not yet improved for the planned development, there is the risk that necessary approvals will not be granted or will be delayed. Construction loans also run the risk that improvements will not be completed on time or in accordance with specifications and projected costs.
	Commercial business: Commercial business loans are extended primarily to middle market customers.  Such credits typically comprise working capital loans, loans for physical asset expansion, asset acquisition loans and other business loans. Loans to closely held businesses will generally be guaranteed in full or for a meaningful amount by the owners of the business. Commercial business loans are made based primarily on the historical and projected cash flow of the borrower and secondarily on the underlying collateral provided by the borrower.  The cash flows of borrowers, however, may not behave as forecasted and collateral securing loans may fluctuate in value due to economic or individual performance factors.  Minimum standards and underwriting guidelines have been established for all commercial and industrial loan types.
	Multifamily: Multifamily loans include loans to finance non-farm properties with five or more units in structures primarily to accommodate households on a temporary or permanent basis. Such credits are typically originated to finance the acquisition of an apartment or condo building/complex. Multifamily loans are made based primarily on the historical and projected cash flow of the subject multifamily property, with assumptions made for vacancy rates. Cash flows and ultimate loan performance rely on the receipt of rental income from the tenants of the property who are themselves subject to fluctuations in national and local economic and unemployment trends.
	Commercial real estate: These loans are primarily secured by office and industrial buildings, warehouses, small retail shopping facilities and various special purpose properties, including hotels and restaurants.  These loans are subject to underwriting standards and processes similar to commercial business loans.  These loans are viewed primarily as cash flow loans and the repayment of these loans is largely dependent on the successful operation of the property.  Loan performance may be adversely affected by factors impacting the general economy or conditions specific to the real estate market such as geographic location and/or property type.
	Consumer and other: These loans may take the form of installment loans, demand loans, or single payment loans, and are extended to individuals for household, family, and other personal expenditures. These include direct consumer automobile loans extended by the Company for the purpose of purchasing a new or used vehicle for personal use. Consumer and installment loans are underwritten by evaluating the credit history of the borrower and the ability of the borrower to meet the debt service requirements of the loan and total debt obligations. Also included in this category are home equity lines of credit. These loans consist of revolving open-end lines of credit secured by 1-4 family residential properties extended to individuals for household, family or other personal expenditures. Underwriting standards for home equity loans are heavily influenced by statutory requirements, which include, but are not limited to, loan-to-value and affordability ratios, risk-based pricing strategies, and documentation requirements.
	The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. In addition, regulatory agencies, as an integral part of their examination processes, periodically review the Company’s allowance for loan losses, and may require the Company to recognize adjustments to its allowance based on their judgments of information available to them at the time of their examinations.
	The allowance consists of specific and general components. The specific component relates to loans that are classified as impaired, and an allowance is established when the collateral value, discounted cash flows or observable market price of the impaired loan are lower than the carrying value of that loan. The general component covers non-impaired loans and is based on the Company’s own loss experience over the most recent two year period, adjusted for qualitative factors. These qualitative factors consider local economic trends, concentrations, management experience and other elements of the Company’s lending operations.
	A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining the impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired.
	Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis by either the fair value of collateral, if the loan is collateral dependent, the present value of expected future cash flows discounted at the loan’s effective interest rate, or the loan’s obtainable market price.
	Single family and consumer and other loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual homogeneous loans for impairment disclosures, unless such loans are the subject of a restructuring agreement due to the financial difficulties of the borrower, the loans are related with another commercial type loan or the loans experience significant payment delinquencies and are not insured.
Troubled debt restructurings	'
	Troubled debt restructurings: Loans are accounted for as troubled debt restructurings when a borrower is experiencing financial difficulties that lead to a restructuring of the loan, and the Company grants a “concession” to the borrower that they would not otherwise consider. These concessions include a modification of terms such as a reduction of the stated interest rate or loan balance, a reduction of accrued interest, an extension of the maturity date at an interest rate lower than a current market rate for a new loan with similar risk, or some combination thereof to facilitate repayment.
	Troubled debt restructurings are classified as impaired loans. Payment performance prior and subsequent to the restructuring is taken into account in assessing whether it is likely that the borrower can meet the new terms. A period of sustained repayment, for at least six months, is generally required for return to accrual status. This may result in the loan being returned to accrual at the time of restructuring. A loan that is modified at a market rate of interest will not be classified as a troubled debt restructuring or impaired in the calendar year subsequent to the restructuring if it is in compliance with the modified terms.
Federal Home Loan Bank stock	'
	Federal Home Loan Bank stock: Federal Home Loan Bank (FHLB) stock consists of the Company’s required investment in the capital stock of the FHLB. No ready market exists for these securities and they have no quoted market value; as such the stock is carried at cost. Management reviews for impairment based on the ultimate recoverability of the cost basis in the FHLB stock, and no impairment has been identified as a result of these reviews.
Foreclosed real estate	'
	Foreclosed real estate: Real estate acquired by foreclosure or by deed in lieu of foreclosure is initially recorded at fair value less cost to sell at the date of foreclosure, establishing a new cost basis. Costs relating to the development and improvement of property are capitalized; holding costs are charged to expense. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of their carrying amount or fair value less cost to sell. Revenues and expenses from operations and changes in the valuation allowance are included in net expenses from foreclosed real estate.
Real estate held for investment	'
	Real estate held for investment: Real estate held for investment includes land, rental properties, and certain real estate development projects. Land and real estate development projects are carried at the lower of cost plus capitalized development period interest, or fair value less costs to sell, and are periodically evaluated for impairment. Rental properties are carried at cost less provisions for depreciation computed by the straight-line method over the estimated life of the property. Rental revenue is recognized on a straight-line basis over the term of the lease unless another systemic and rational basis is more representative of the time pattern in which the use benefit is derived from the leased property. The difference between rental income earned on a straight-line basis and the cash rent due under provisions of the lease agreements is recorded as deferred rent receivable and is included as a component of other assets in the accompanying consolidated balance sheets.
	The Company evaluates the carrying value of all real estate held when an indicator of impairment is deemed to exist. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount which the carrying amount of the asset exceeds the fair value of the asset. If the Company intends to dispose of its assets, the assets would be separately presented in the consolidated balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and would no longer be depreciated.
	A property is considered held for sale when a contract for sale is entered into or when management has committed to a plan to sell an asset, the asset is actively marketed, and sale is expected to occur within one year.
Office properties and equipment	'
	Office properties and equipment: Office properties including equipment are stated at cost less accumulated depreciation, and include expenditures for new facilities and items that substantially increase the useful lives of existing buildings and equipment. Expenditures for normal repairs and maintenance are charged to expense as incurred. When properties are retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the respective accounts and the resulting gain or loss is recorded.
Mortgage servicing rights and Transfers of financial assets	'
	Mortgage servicing rights: Mortgage servicing rights (MSRs) are initially recognized at fair value when loans have been sold to investors and are amortized over the lives of the loans. Upon sale of loans with servicing retained, the servicing rights are recorded at fair value and remaining proceeds received are allocated to the loan. Amortization of MSRs is based on the ratio of net servicing income received in the current period, to total remaining net servicing income projected to be realized from the MSRs. MSRs are periodically assessed for impairment, which is calculated using estimated net cash flow analysis on a discounted basis. Impairment is recognized in the statement of income, during the period in which it occurs, as an adjustment to the corresponding valuation allowance. For purposes of performing an impairment evaluation, the serviced loan portfolio is stratified on the basis of certain risk characteristics including loan type (i.e., fixed or adjustable interest rates).
	Transfers of financial assets: Transfers of financial assets are accounted for as sales only when the control over the financial assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of the right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets.
Employee stock ownership plan	'
	Employee stock ownership plan: The Company has an employee stock ownership plan (ESOP) covering substantially all employees. The cost of shares issued to the ESOP but not yet allocated to participants is presented in the consolidated balance sheets as a reduction of stockholders' equity. Compensation expense is recorded based on the market price of the shares as they are committed to be released for allocation to participant accounts.
Income taxes	'
	Income taxes: The Company, the Bank, and its subsidiaries file consolidated federal income tax returns and combined state income tax returns. Accordingly, amounts equal to tax benefits of those companies having taxable federal losses or credits are reimbursed by the other companies that incur tax liabilities.
	Deferred income taxes are provided using the liability method whereby deferred tax assets are recognized for deductible temporary differences and operating loss and tax credit carryforwards and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of the changes in tax laws and rates as of the date of enactment.
	The Company accounts for uncertainty in income taxes to determine whether tax benefits claimed or expected to be claimed on a tax return, should be recorded in the consolidated financial statements. The Company may recognize the tax benefit for an uncertain tax position if it is more-likely-than-not that the tax position will be sustained upon examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being utilized upon ultimate settlement.
	It is the Company’s policy that interest and penalties associated with unrecognized tax benefits are classified as additional income taxes in the statement of operations.
Derivative financial instruments and hedging activities	'
	Derivative financial instruments and hedging activities: All derivatives are recognized in the consolidated balance sheets at their fair value. Derivative contracts are maintained related to commitments to fund residential mortgages (interest rate locks) in connection with residential mortgages intended for sale. Such commitments are recorded at fair value in other assets or liabilities, with changes in fair value recorded in net gain or loss on sale of mortgage loans. Fair value is based on fees currently charged to enter into similar agreements, and for fixed rate commitments, also considers the committed rates and current levels of interest rates. Derivative contracts are also maintained related to certificates of deposit, for which changes in the fair value of the derivative are recorded in earnings.
Comprehensive income	'
	Comprehensive income: Comprehensive income consists of net income and other comprehensive income. Other comprehensive income includes unrealized gains and losses on securities available-for-sale, which are also recognized as separate components of equity.
Reclassification	'
	Reclassification: Certain amounts in the 2012 consolidated financial statements have been reclassified to conform to the 2013 presentation. These reclassifications had no effect on net income or loss.
Segment reporting	'
	Segment reporting: The Company views the Bank as one operating segment, therefore, separate reporting of financial segment information is not considered necessary. The Company approaches the Bank and its other subsidiaries as one business enterprise, which operates in a single economic environment, since the products and services, types of customers and regulatory environment all have similar characteristics.
Recent accounting pronouncements	'
	Recent accounting pronouncements: In April 2011, the FASB issued ASU 2011-02, A Creditor’s Determination of Whether a Restructuring Is a Troubled Debt Restructuring. ASU 2011-02 amends ASC Topic 310, Receivables, by clarifying guidance for creditors in determining whether a concession has been granted and whether a debtor is experiencing financial difficulties. ASU 2011-02 is effective for annual periods ending on or after December 15, 2012 and has been adopted with no impact on the consolidated financial statements and related disclosures.
	In April 2011, the FASB issued ASU 2011-03, Transfers and Servicing (Topic 860) - Reconsideration of Effective Control for Repurchase Agreements. ASU 2011-03 is intended to improve financial reporting of repurchase agreements and other agreements that both entitle and obligate a transferor to repurchase or redeem financial assets before their maturity. ASU 2011-03 removes from the assessments of effective control (i) the criteria requiring the transferor to have the ability to repurchase or redeem the financial asset on substantially the agreed terms, even in the event of default by the transferee, and (ii) the collateral maintenance guidance related to that criterion. ASU 2011-03 was effective for the Company on January 1, 2012 and has been adopted with no impact on the consolidated financial statements and related disclosures.
	In May 2011, the FASB issued ASU 2011-04, Fair Value Measurement (Topic 820) - Amendments to Achieve Common Fair Value Measurements and Disclosure Requirements in U.S. GAAP and IFRS. ASU 2011-04 amends Topic 820, Fair Value Measurements and Disclosures, to converge the fair value measurement guidance U.S. GAAP and International Financial Reporting Standards. ASU 2011-04 clarifies the application of existing fair value measurement requirements, changes certain principles in Topic 820 and requires additional fair value disclosures. ASU 2011-04 is effective for annual periods beginning after December 15, 2011. The guidance primarily impacts fair value disclosures related to Level 3 fair value measurements, and has been adopted with no impact on the consolidated financial statements and related disclosures.
	In June 2011, the FASB issued ASU 2011-05, Comprehensive Income (Topic 220) - Presentation of Comprehensive Income. ASU 2011-05 amends Topic 220, Comprehensive Income, to require that all non-owner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The amendments do not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. Additionally, ASU 2011-05 requires entities to present, on the face of the financial statement, reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement or statements where the components of net income and the components of other comprehensive income are presented. The option to present components of net income and the components of other comprehensive income as part of the statement of changes in stockholders’ equity was eliminated. ASU 2011-05 is effective for fiscal years ending after December 15, 2012 and has been adopted in these consolidated financial statements.
	In February 2013, the FASB issued ASU 2013-02, Comprehensive Income (Topic 220) - Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. ASU 2013-02 amends Topic 220, Comprehensive Income, to require that amounts reclassified out of accumulated other comprehensive income be reported on the appropriate line item of the statement of operations if the amount being reclassified is required by U.S. GAAP to be included in its entirety in net income. ASU 2013-02 is effective for reporting periods beginning after December 31, 2012 and has been adopted in these consolidated financial statements.
	In July 2013, the FASB issued ASU 2013-11, Income Taxes (Topic 740) - Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss or a Tax Credit Carrryforward Exists. ASU 2013-11 is intended to clarify the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss or a tax credit carrryforward exists. This presentation had not been addressed in Topic 740 and there was diversity in reporting practices in those instances. ASU 2013-11 requires an unrecognized tax benefit to be presented as a liability and not netted against a deferred tax asset. ASU 2013-11 is effective for reporting periods beginning after December 15, 2013. Adoption by the Company is not expected to have an impact on the consolidated financial statements and related disclosures.
