Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]	1. Summary of Significant Accounting Policies
	Business Bank Mutual Corporation (the “Company”), a Wisconsin corporation, is a federal unitary savings and loan holding company which holds all of the outstanding shares of Bank Mutual (the “Bank”). The Bank is a federal savings bank offering a full range of financial services to customers who are primarily located in the state of Wisconsin. The Bank is principally engaged in the business of attracting deposits from the general public, including businesses and government entities, and using such deposits to originate secured and unsecured loans to commercial and retail borrowers.
	Principles of Consolidation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States. The consolidated financial statements include the accounts and transactions of the Company and its wholly-owned subsidiaries. The Bank has the following active wholly-owned subsidiaries: BancMutual Financial & Investment Services, Inc., and MC Development Ltd. MC Development Ltd. owns a 50% interest in Arrowood Development LLC, which is a variable interest entity and is consolidated into the financial statements. All intercompany accounts and transactions have been eliminated in consolidation.
	In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the statement of financial condition and revenues and expenses for the period. Actual results could differ from those estimates.
	Cash and Cash Equivalents The Company considers interest-bearing deposits in banks and federal funds sold that have original maturities of three months or less to be cash equivalents. Under Regulation D, the Bank is required to maintain cash and reserve balances with the Federal Reserve Bank of Chicago. The average amount of required reserve balances for the years ended December 31, 2014 and 2013, was $14,525 and $12,921, respectively.
	Federal Home Loan Bank Stock Stock of the Federal Home Loan Bank of Chicago (“FHLB of Chicago”) is owned due to membership requirements and is carried at cost, which is its redemption value, and is included in other assets. FHLB stock is periodically reviewed for impairment based on management’s assessment of the ultimate recoverability of the investment rather than temporary declines in its estimated fair value.
	Securities Available-for-Sale and Held-to-Maturity Available-for-sale securities are stated at fair value, with the unrealized gains and losses, net of tax, reported as a separate component of accumulated other comprehensive loss in shareholders’ equity. Held-to-maturity securities are stated at amortized cost.
	The amortized cost of securities classified as available-for-sale or held-to-maturity is adjusted for amortization of premiums and accretion of discounts to maturity, or in the case of mortgage-related securities, over the estimated life of the securities. Such accretion or amortization is included in interest income from investments. Interest and dividends are included in interest income from investments. Realized gains and losses and declines in value judged to be other-than-temporary are included in net gain or loss on sales of securities and are based on the specific identification method.
	Impairment of available-for-sale and held-to-maturity securities is evaluated considering numerous factors, and their relative significance varies case-by-case. Factors considered include the length of time and extent to which the market value has been less than cost; the financial condition and near-term prospects of the issuer of a security; and the Company’s intent and/or likely need to sell the security before its anticipated recovery in fair value. Further, if the Company does not expect to recover the entire amortized cost of the security (i.e., a credit loss is expected), the Company will be unable to assert that it will recover its cost basis even if it does not intend to sell the security. If, based upon an analysis of each of these factors, it is determined that the impairment is other-than-temporary, the carrying value of the security is written down through earnings by the amount of the expected credit loss.
	Loans Receivable and Loans Held-for-Sale Loans receivable are recorded at cost, net of undisbursed loan proceeds, allowance for loan losses, unamortized deferred fees and costs, and unamortized purchase premiums or discounts, if any. Loan origination and commitment fees and certain direct loan origination costs are deferred and amortized as an adjustment of loan yield. Purchase premiums and discounts are also amortized as an adjustment of yield.
	Loans held-for-sale, which generally consists of recently originated fixed-rate residential mortgage loans, are recorded at market value determined on an individual loan basis. Fees received from the borrower are deferred and recorded as an adjustment of the carrying value.
	Accrued Interest on Loans Interest on loans receivable is accrued and credited to income as earned. The Company measures the past due status of a loan by the number of days that have elapsed since the borrower has failed to make a contractual loan payment. Accrual of interest is generally discontinued when either (i) reasonable doubt exists as to the full, timely collection of interest or principal or (ii) when a loan becomes past due by more than 90 days. At that time, the loan is considered impaired and any accrued but uncollected interest is reversed. Additional interest income is recorded only to the extent that payments are received, collection of the principal is reasonably assured, and/or the net recorded investment in the loan is deemed to be collectible. Loans are generally restored to accrual status when the obligation is brought to a current status by the borrower.
	Allowance for Loan Losses and Impaired Loans The Company classifies its loan portfolio into six segments for purposes of determining its allowance for loan losses: commercial and industrial, commercial real estate, multi-family real estate, construction and development, one- to four-family real estate, and home equity and other consumer. This segmentation is based on the nature of the loan collateral and the purpose of the loan, which in the judgment of management are the primary risk characteristics that determine the allowance for loan loss. Loans in the commercial and industrial segment are typically secured by equipment, inventory, receivables, other business assets, and in some instances, business and personal real estate, or may be unsecured. Loans in the commercial real estate, multi-family real estate, and one- to four-family real estate segments are secured principally by real estate. The commercial real estate segment consists of non-residential loans secured by office, retail/wholesale, industrial/warehouse, and other properties. The construction and development segment consists of loans secured by commercial real estate, multi-family, and developed and undeveloped land. Loans in the home equity and other consumer segment may be secured by real estate, personal property, or may be unsecured.
	The allowance for loan losses for each segment is maintained at a level believed adequate by management to absorb probable losses inherent in each segment and is based on factors such as the size and current risk characteristics of the segments, an assessment of individual problem loans and pools of homogenous loans within the segments, and actual loss, delinquency, and/or risk rating experience within the segments. The Company also considers current economic conditions and/or events in specific industries and geographical areas, including unemployment levels, trends in real estate values, peer comparisons, and other pertinent factors, to include regulatory guidance. Finally, as appropriate, the Company also considers individual borrower circumstances and the condition and fair value of the loan collateral, if any.
	The allowance for loan losses for each segment is determined using a combined approach. Individual loans in the segments that have been identified as impaired are analyzed individually to determine an appropriate allowance for loan loss. In addition, the allowance for loan losses for each segment is augmented using a homogenous pool approach for loans in each segment that are current and/or have not been individually identified as impaired loans. The homogenous approach utilizes loss rates that are developed by management using the qualitative factors and other considerations outlined in the previous paragraph.
	Loans are considered impaired when they are identified as such by the Company’s internal risk rating and loss evaluation process or when contractually past due 90 days or more with respect to interest or principal. Factors that indicate impairment include, but are not limited to, deterioration in a borrower’s financial condition, performance, or outlook, decline in the condition, performance, or fair value of the collateral for the loan (if any), payment or other default on the loan, and adverse economic or market developments in the borrower’s region or business segment. Accrual of interest is typically discontinued on impaired loans, although from time-to-time the Company may continue to accrue interest and/or recognize interest income on impaired loans when payments are being received and, in the judgment of management, collection of the principal is reasonably assured and/or the net recorded investment in the loan is deemed to be collectible.
	The Company has various policies and procedures in place to monitor its exposure to credit risk including, but not limited to, a formal risk rating process, periodic loan delinquency reporting, periodic loan file reviews, financial updates from and visits to borrowers, and established past-due loan collection procedures. The Company formally evaluates its allowance for loan losses on a quarterly basis or more often as deemed necessary. A provision for loan loss is charged to operations based on this periodic evaluation. Actual loan losses are charged off against the allowance for loan losses, while recoveries of amounts previously charged off are credited to the allowance.
	Determination of the allowance is inherently subjective as it requires significant estimates, including the amounts and timing of expected future cash flows on loans, the fair value of underlying collateral (if any), estimated losses on pools of homogeneous loans based on historical loss experience, changes in risk characteristics of the loan portfolio, and consideration of current economic trends, all of which may be susceptible to significant change.
	Mortgage Servicing Rights Mortgage servicing rights are recorded as an asset when loans are sold with servicing rights retained. The total cost of loans sold is allocated between the loan balance and their servicing asset based on their relative fair values. The capitalized value of mortgage servicing rights is amortized in proportion to, and over the period of, estimated net future servicing revenue. Mortgage servicing rights are carried at the lower of the initial carrying value, adjusted for amortization, or estimated fair value. The carrying values are periodically evaluated for impairment. For purposes of measuring impairment, the servicing rights are stratified into pools based on term and interest rate. Impairment represents the excess of the remaining capitalized cost of a stratified pool over its fair value, and is recorded through a valuation allowance. The fair value of each servicing rights pool is calculated based on the present value of estimated future cash flows using a discount rate, given current market conditions. Estimates of fair value include assumptions about prepayment speeds, interest rates and other factors which are subject to change over time. Changes in these underlying assumptions could cause the fair value of mortgage servicing rights, and the related valuation allowance, if any, to change significantly in the future.
	Derivative Financial Instruments In connection with its mortgage banking activities, the Company enters into loan commitments to fund residential mortgage loans at specified interest rates and within specified periods of time, generally up to 60 days from the time of rate lock. A loan commitment whose loan arising from exercise of the loan commitment will be held for sale upon funding is a derivative instrument, which must be recognized at fair value on the consolidated balance sheet in other assets and other liabilities with changes in its value recorded in income from mortgage banking operations.
	In determining the fair value of its derivative loan commitments for economic purposes, the Company considers the value that would be generated when the loan arising from exercise of the loan commitment is sold in the secondary mortgage market. That value includes the price that the loan is expected to be sold for in the secondary mortgage market.
	The Company enters into interest rate swap arrangements to manage the interest rate risk exposure associated with specific commercial loan relationships at the time such loans are originated. These interest rate swaps, as well as the embedded derivatives associated with certain of the Company’s commercial loan relationships, are derivative instruments under GAAP. The Company has not designated any of these derivative instruments as accounting hedges as specified in GAAP. As such, the fair market value of interest rate swaps and embedded derivatives are included in the Company’s assets or liabilities, as the case may be, and periodic changes in fair market value of such derivative instruments are recorded through periodic earnings in other non-interest income.
	Foreclosed Properties and Repossessed Assets Foreclosed properties acquired through, or in lieu of, loan foreclosure are recorded at the lower of cost or fair value less estimated costs to sell. Costs related to the development and improvement of property are capitalized provided such costs do not result in a carrying value in excess of the property’s fair value less estimated costs to sell, in which case such costs are expensed. Costs related to holding the property are expensed. Gains and losses on sales are recognized based on the carrying value upon closing of the sale.
	Premises and Equipment Land, buildings, leasehold improvements and equipment are carried at amortized cost. Buildings and equipment are depreciated over their estimated useful lives (office buildings 30 to 45 years and furniture and equipment 3 to 10 years) using the straight-line method. Leasehold improvements are amortized over the shorter of their useful lives or expected lease terms. The Company reviews buildings, leasehold improvements and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Impairment exists when the estimated undiscounted cash flows for the property are less than its carrying value. If identified, an impairment loss is recognized through a charge to earnings based on the fair value of the property.
	Life Insurance Policies Investments in life insurance policies owned by the Company are carried at the amount that could be realized under the insurance contract if the Company cashed them in on the respective dates.
	Income Taxes The Company files consolidated federal and combined state income tax returns. A deferred tax asset or liability is determined based on the enacted tax rates that will be in effect when the differences between the financial statement carrying amounts and tax basis of existing assets and liabilities are expected to be reported in the Company’s income tax returns. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date of the change. A valuation allowance is provided for any deferred tax asset for which it is more likely than not that the asset will not be realized. Changes in valuation allowances are recorded as a component of income taxes.
	In 2013 the IRS issued final tangible property regulations to be effective for the Company’s 2014 federal income tax return. The Company’s adoption of these rules is not expected to have a significant impact on the Company’s financial condition or results of operations.
	Earnings (Loss) Per Share Basic and diluted earnings (loss) per share (“EPS”) are computed by dividing net income by the weighted-average number of common shares outstanding for the period. Vested shares of restricted stock which have been awarded under provisions of the Company's 2004 and 2014 Stock Incentive Plans are also considered outstanding for basic EPS. Non-vested restricted stock and stock option shares are considered dilutive potential common shares and are included in the weighted-average number of shares outstanding for diluted EPS.
	Pension Costs The Company has a qualifying defined benefit plan and a supplemental defined benefit plan. As appropriate, the net periodic pension cost of these plans consists of the expected cost of benefits earned by employees during the current period and an interest cost on the projected benefit obligation, reduced by the expected earnings on assets held by the plans, amortization of prior service cost, and amortization of recognized actuarial gains and losses over the estimated future service period of existing plan participants. Effective January 1, 2014, the Company froze the benefits of participants in the qualified defined benefit pension plan that had less than 20 years of service. This change also resulted in the future benefits under the Company’s supplemental defined benefit pension plan being effectively frozen.
	The Company also has a defined contribution plan. The costs associated with the defined contribution plan consist of a predetermined percentage of individual participant compensation, as well as the cost of discretionary contributions determined by the Company’s board of directors.
	Segment Information The Company has determined that it has one reportable segment—community banking. The Company offers a range of financial products and services to external customers, including: accepting deposits from the general public, originating secured and unsecured loans to commercial and retail borrowers, and marketing annuities and other insurance products.
	Recent Accounting Changes In 2011 the Financial Accounting Standards Board (“FASB”) issued new accounting guidelines related to the disclosure of both gross information and net information about instruments eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting agreement. The guidance was effective for interim and fiscal periods beginning on or after January 1, 2013, which for the Company was the first quarter of 2013. The Company's adoption of these new accounting guidelines did not have a material impact on its results of operations or financial condition. However, the guidelines do affect how matters may be disclosed in the financial statements.
	In 2012 the FASB issued new accounting guidance related to (i) testing indefinite-lived intangible assets for impairment and (ii) subsequent measurement of an indemnification asset recognized in a government-assisted acquisition of a financial institution. Item (i) was effective for years beginning after September 15, 2012, which was the first quarter of 2013 for the Company. Item (ii) was effective for fiscal years beginning on or after December 15, 2012, which was the first quarter of 2013 for the Company. The Company’s adoption of these new guidelines did not have a material impact in its results of operations or financial condition.
	In 2013 the FASB issued new accounting guidance relating to (i) the reporting of reclassifications out of accumulated other comprehensive income or loss; and (ii) the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date. Item (i) was effective for fiscal years beginning after December 15, 2012, which was the first quarter of 2013 for the Company. The adoption of this item did not have an effect on the Company’s results of operations or financial condition. Item (ii) was effective for fiscal years beginning after December 15, 2013, which was the first quarter of 2014 for the Company. Adoption of this item did not have a material impact on the Company’s results of operations or financial condition.
	In 2013 the FASB issued new accounting guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carry forward, a similar tax loss, or a tax credit carry forward exists. The guidance was effective for fiscal years and interim periods beginning after December 15, 2013, which was the first quarter of 2014 for the Company. Adoption of this item did not have a material impact on the Company’s results of operations or financial condition.
	In the first quarter of 2014 the FASB issued new accounting guidance related to troubled debt restructurings by creditors to clarify when an in-substance repossession or foreclosure occurs as satisfaction of a consumer mortgage loan. Although the new guidance is effective for fiscal years beginning after December 15, 2014, which would be the first quarter of 2015 for the Company, early adoption of the new guidance is permitted. Accordingly, the Company adopted the new guidance in the first quarter of 2014 using a prospective transition method. Adoption of this new guidance did not have a material impact on the Company’s results of operations or financial condition. However, it did affect how certain matters are disclosed in the financial statements.
	In the second quarter of 2014 the FASB issued new accounting guidance related to the recognition of revenue from contracts with customers. The guidance is effective for fiscal years and interim periods beginning after December 15, 2016, which will be the first quarter of 2017 for the Company. The Company’s adoption of this item is not expected to have a material impact on its results of operations or financial condition.
	In the third quarter of 2014 the FASB issued new accounting guidance related to the classification and measurement of certain government-guaranteed mortgages upon foreclosure. The guidance is effective for fiscal years and interim periods beginning after December 15, 2014, which will be the first quarter of 2015 for the Company. The Company’s adoption of this item is not expected to have a material impact on its results of operations or financial condition.
	Reclassifications Certain components of non-interest income in 2013 and 2012 were reclassified to conform to the 2014 presentation format. For the years ended December 31, 2013 and 2012, $6,769 and $6,903 that had been previously reported as “service charges on deposits” in such periods, respectively, were renamed as “deposit-related fees and charges.” These amounts were combined with $5,427 and $5,134 of other fee income from deposit customers that had been previously included in “other non-interest income” in those periods, respectively. Also, for the same years, respectively, net loan servicing revenue of $2,471 and $(2,606) was reclassified from “loan-related fees and servicing revenue, net” and was combined with $4,405 and $13,206 in “gain on loan sales activities, net” and the aggregate amount reported as “mortgage banking revenue, net.” Finally, $844 and $695 in 2013 and 2012, respectively, that was previously included in “loan-related fees and servicing revenue, net,” was reclassified to “other non-interest income.”

	None of the Company’s mortgage-related securities held-to-maturity at December 31, 2014, had an unrealized loss.
	The Company determined that the unrealized losses on its mortgage-related securities were temporary as of December 31, 2014 and 2013. The Company does not intend to sell these securities and it is unlikely that it will be required to sell these securities before the recovery of their amortized cost. The Company believes it is probable that it will receive all future contractual cash flows related to these securities. This determination was based on management’s judgment regarding the nature of the loan collateral that supports the securities, a review of the current ratings issued on the securities by various credit rating agencies, recent trends in the fair market values of the securities and, in the case of private-label CMOs, a review of the actual delinquency and/or default performance of the loan collateral that supports the securities.
	As of December 31, 2014 and 2013, the Company had private-label CMOs with a fair value of $23,254 and $28,844 respectively, and unrealized gains of $480 and $501, respectively that were rated less than investment grade. These private-label CMOs were analyzed using modeling techniques that considered the priority of cash flows in the CMO structure and various default and loss rate scenarios that management considered appropriate given the nature of the loan collateral. In 2012 the Company recognized $400 in net OTTI losses related to its investment on a number of private-label CMOs. No such losses were recognized in 2014 and 2013. The determination of the net OTTI losses in 2012 was based on modeling techniques that considered the priority of cash flows in the CMO structure and various default and loss rate scenarios that management considered appropriate given the nature of the loan collateral. The following assumptions were used in determining the amount of the credit loss in 2012: (i) prepayment speeds with a range of 5.5% to 16.5% and a weighted-average rate of 9.9%, (ii) default rates with a range of 4.0% to 5.5% and a weighted-average rate of 4.4%, (iii) loss severity rates with a range of 40.0% to 52.0% and a weighted-average rate of 42.1%, and (iv) current credit enhancements with a range of 0.5% to 4.6% and a weighted-average rate of 3.0%.
	The following table contains a summary of OTTI related to credit losses that have been recognized in earnings as of the dates indicated, as well as the end of period values for securities that have experienced such losses:
		Year Ended December 31
		2014		2013		2012
	Beginning balance of unrealized OTTI related to credit losses	$	789	$	789	$	389

	Additional unrealized OTTI related to credit losses for which OTTI was previously recognized		–		–		254
	Net OTTI losses recognized in earnings		–		–		400
Ending balance of unrealized OTTI related to credit losses	$	789	$	789	$	789
Adjusted cost at end of period	$	5,504	$	7,152	$	9,541
Estimated fair value at end of period	$	6,065	$	7,649	$	9,908
Results of operations included gross realized gains on the sale of securities available-for-sale of $102 and $543 in 2014 and 2012, respectively. There were no gross realized losses on the sale of such securities in those same years. In addition, there were no gross realized gains or losses on the sale of securities available-for-sale in 2013.
Mortgage-related securities with a fair value of approximately $79,753 and $74,988 at December 31, 2014 and 2013, respectively, were pledged to secure deposits, FHLB advances, and for other purposes as permitted or required by law.

The Company adjusts certain factors used to determine the allowance for loan losses on loans that are collectively evaluated for impairment. Management considered these adjustments necessary and prudent in light of general uncertainties related to trends in real estate values, economic conditions, and unemployment. The Company estimates that these changes, as well as overall changes in the balance of loans to which the various factors were applied, resulted in a decrease of $1,180 in 2014, an increase of $3,029 in 2013, and a decrease of $87 in 2012, in the total allowance for loan losses.
The following tables present information regarding impaired loans that have a related allowance for loan loss and those that do not as of the dates indicated (the loans receivable amounts in the tables are net of undisbursed loan proceeds):

Loans rated “pass” or “watch” are generally current on contractual loan and principal payments and comply with other contractual loan terms. Pass loans generally have no noticeable credit deficiencies or potential weaknesses. Loans rated watch, however, will typically exhibit early signs of credit deficiencies or potential weaknesses that deserve management’s close attention. Loans rated “special mention” do not currently expose the Company to a sufficient degree of risk to warrant a lower rating, but possess clear trends in credit deficiencies or potential weaknesses that deserve management’s close attention. The allowance for loan losses on loans rated pass, watch, or special mention is typically evaluated collectively for impairment using a homogenous pool approach. This approach utilizes quantitative factors developed by management from its assessment of historical loss experience, qualitative factors, and other considerations.
Loans rated “substandard” involve a distinct possibility that the Company could sustain some loss if deficiencies associated with the loan are not corrected. Loans rated “doubtful” indicate that full collection is highly questionable or improbable. The Company did not have any loans that were rated doubtful at December 31, 2014 and 2013. Loans rated substandard or doubtful that are also considered in management’s judgment to be impaired are generally analyzed individually to determine an appropriate allowance for loan loss. A loan rated “loss” is considered uncollectible, even if a partial recovery could be expected in the future. The Company generally charges off loans that are rated as a loss. As such, the Company did not have any loans that were rated loss at December 31, 2014 and 2013.

As of December 31, 2014 and 2013, $540 and $443 in student loans, respectively, were 90-days past due, but remained on accrual status. No other loans 90-days past due were in accrual status as of December 31, 2014 and 2013.
The Company classifies a loan modification as a troubled debt restructuring (“TDR”) when it has granted a borrower experiencing financial difficulties a concession that it would otherwise not consider. Loan modifications that result in insignificant delays in the receipt of payments (generally six months or less) are not considered TDRs under the Company’s TDR policy. TDRs are relatively insignificant and/or infrequent in the Company and generally consist of loans placed in interest-only status for a short period of time or payment forbearance for greater than six months. As of December 31, 2014 and 2013, TDRs were $4,872 and $4,298, respectively, and consisted primarily of one- to four-family mortgage loans. TDRs in accrual status as of those same dates were $3,315 and $3,310, respectively. Additions to TDRs during the twelve month periods ended as of those dates were immaterial. In addition, TDRs that experienced a payment default within one year of their restructuring were also immaterial during these twelve month periods. TDRs are evaluated for impairment and appropriate credit losses are recorded in accordance with the Company’s accounting policies and GAAP.

Stockholders' Equity Note [Abstract]
Stockholders' Equity Note Disclosure [Text Block]	8. Shareholders’ Equity
	The Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possible additional discretionary, actions by regulators, that, if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines, the Bank must meet specific capital guidelines that involve quantitative measures of its 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.
	Quantitative measures established by federal regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in the following table) of total and Tier I capital to risk-weighted assets, and of Tier I capital to average assets (as these terms are defined in regulations). Management believes, as of December 31, 2014, that the Bank met all capital adequacy requirements. Management is not aware of any conditions or events, which would change the Bank’s status as well capitalized.
	The Bank’s actual and required regulatory capital amounts and ratios as of December 31, 2014 and 2013, are presented in the following table:

Compensation and Retirement Disclosure [Abstract]
Pension and Other Postretirement Benefits Disclosure [Text Block]	10. Employee Benefit Plans
	The Company has a discretionary, defined contribution savings plan (the “Savings Plan”). The Savings Plan is qualified under Sections 401 and 401(k) of the Internal Revenue Code and provides employees meeting certain minimum age and service requirements the ability to make contributions to the Savings Plan on a pretax basis. The Company then matches a percentage of the employee’s contributions. Matching contributions made by the Company were $648 in 2014, $206 in 2013, and $198 in 2012.
	The Company also has a qualified defined benefit pension plan covering employees meeting certain minimum age and service requirements and a supplemental defined benefit pension plan for certain eligible employees. The supplemental pension plan is funded through a "rabbi trust" arrangement. The benefits under these plans are generally based on years of service and the employee’s average annual compensation for five consecutive calendar years in the last ten calendar years which produces the highest average. The Company’s funding policy is to contribute annually the amount necessary to satisfy the requirements of the Employee Retirement Income Security Act of 1974.
	Effective January 1, 2013, the Company closed the qualified defined benefit pension plan to employees that were not eligible to participate in the plan as of that date, as well as any employees hired after that date. In addition, effective for service performed after March 1, 2013, the Company reduced certain benefits paid under the qualified and supplemental plans related to any employee service performed after that date. Finally, effective January 1, 2014, the Company froze the benefits of participants in the qualified defined benefit pension plan that had less than 20 years of service. This change also resulted in the future benefits under the Company’s supplemental defined benefit pension plan being effectively frozen. The effect of freezing the qualified plan was a curtailment gain, which reduced the projected benefit obligation and the unrecognized loss by $2,395 in 2013. This amount was recognized through accumulated other comprehensive loss in 2013.
	The changes in plan assets and benefit obligations at December 31, 2014 and 2013, are presented in the following table.
		Qualified						Supplemental
		Pension Plan						Pension Plan
		2014			2013			2014			2013

	Funded status at the end of the year	$	-21,598		$	-8,598		$	-11,114		$	-10,183
	The underfunded status of the qualified and supplemental pension plans at December 31, 2014, are recognized in the Consolidated Statement of Financial Condition as accrued pension liability, which is included as a component of other liabilities.
	The following tables summarize the changes in pension plan assets and benefit obligations recognized in accumulated other comprehensive loss, net of related income tax effect, for the periods indicated:
		Qualified						Supplemental
		Pension Plan						Pension Plan
		2014			2013			2014			2013
	Balance in accumulated other comprehensive loss at the beginning of year	$	-5,857		$	-9,844		$	-661			-1,154
	Change in unrecognized loss		-6,999			2,550			-941			467
	Curtailment gain on plan amendment		–			1,437			–			–
	Change in prior service cost		–			–			–			26
	Total recognized in other comprehensive loss		-6,999			3,987			-941			493
	Balance in accumulated other comprehensive loss at the end of year	$	-12,856		$	-5,857		$	-1,602		$	-661
	The $1,602 in accumulated other comprehensive loss as of December 31, 2014, for the supplemental pension plan consisted of $1,602 in unrecognized loss. The $661 in accumulated other comprehensive loss as of December 31, 2013, for the supplemental pension plan consisted of $635 in unrecognized loss and $26 in prior service costs. All period-end balances in the table for the qualified pension plan consisted of unrecognized loss.
	The estimated net of tax costs that will be amortized from accumulated other comprehensive loss into net periodic cost in 2015 is $2,623 for the qualified plan. The accumulated benefit obligations for the qualified defined benefit pension plan were $70,163 at December 31, 2014, and $54,703 at December 31, 2013.
	The assumptions used to determine the benefit obligations as of December 31 is as follows:
		2014			2013
	Discount rate		3.74	%		4.7	%
	Rate of increase in compensation levels		3			3
	Expected long-term rate of return on plan assets (qualified plan)		6			6
	The assumptions used to determine the net cost for the years ended December 31 is as follows:
		2014			2013			2012
	Discount rate		4.7	%		3.7	%		4.21	%
	Rate of increase in compensation levels		3			3			3
	Expected long-term rate of return on plan assets (qualified plan)		6			6.5			6.5
	The expected long-term rate of return was estimated using a combination of the historical and expected rate of return for immediate participation guarantee contracts, which is the primary asset of the qualified plan.
	Using an actuarial measurement date of December 31, 2014, 2013, and 2012, components of net periodic benefit cost follow:
		2014			2013			2012
	Qualified pension plan:
	Interest cost	$	2,668		$	2,300		$	2,254
	Service cost		897			3,081			2,898
	Expected return on plan assets		-2,891			-3,297			-3,022

	Service cost		–			160			116
	Amortization of prior service cost		–			44			13
	Amortization of net loss from earlier periods		6			368			–
	Net periodic cost	$	459		$	960		$	506
	At December 31, 2014, the projected benefit payments for each of the plans are as follows:

The investment objective is to minimize risk. The assets of the qualified pension plan are concentrated in a group annuity contract issued by a life insurance company. Pension plan contributions are maintained in the general account of the insurance company, which invests primarily in corporate and government notes and bonds with ten to fifteen years to maturity. The group annuity contract is valued at fair value by discounting the related cash flows based on current yields of similar instruments with comparable durations and considering the credit worthiness of the issuer.
The equity securities are shares of stock issued by the life insurance company when it demutualized. This investment is valued at the closing price reported in the active market in which the security is traded. The money market fund, which invests in short-term U.S. government securities, is based on a $1.00 net asset value (“NAV”) specified by the fund manager. The fund is not traded in an active market. The fund manager bases its estimate of the NAV on quoted prices for similar assets in active markets.
The following table presents a summary of the changes in the fair value of the pension plan’s Level 3 asset during the periods indicated. As noted above, the Company’s Level 3 asset consists entirely of a group annuity contract issued by an insurance company.

The Company has a deferred retirement plan for certain non-officer directors who have provided at least five years of service. All eligible directors’ benefits have vested. In the event a director dies prior to completion of these payments, payments will go to the director’s heirs. The Company has funded these arrangements through “rabbi trust” arrangements and, based on actuarial analyses, believes these obligations are adequately funded. The Company also has supplemental retirement plans for certain executives of a financial institution it acquired in 2000.
The liabilities related to these plans were $4,258 and $3,553 at December 31, 2014 and 2013 respectively. The net expense related to these plans for the years ended December 31, 2014, 2013, and 2012 was $839, $199, and $189, respectively.

	In 2004 the Company’s shareholders approved the 2004 Stock Incentive Plan (the “2004 Plan”). Options granted under the 2004 Plan vested over five years and had expiration terms of ten years. The 2004 Plan also provided for restricted stock awards that also vested over five years. The 2004 Plan terminated on February 1, 2014, in accordance with the terms of the plan. Options awarded under the 2004 Plan will remain outstanding until exercised, forfeited, or expired.
	In May 2014 the Company’s shareholders approved the 2014 Incentive Compensation Plan (the “2014 Plan”), which provides for the award of stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, and cash awards. Stock-related awards under the 2014 Plan vest over a period of three or more years and, if applicable, have a maximum term of ten years. The number of shares of common stock of the Company that may be issued under the 2014 Plan is limited to 3,000,000 shares. As of December 31, 2014, 2,939,500 shares remain eligible for award under the 2014 Plan.
	The Company has no stock compensation plans that have not been approved by shareholders.
	Restricted stock grants are amortized to compensation expense as the Company’s employees and directors become vested in the shares. The amount amortized to expense was $376 , $237 , and $186 in 2014, 2013, and 2012, respectively. Outstanding non-vested restricted stock grants had a fair value of $1,382 and an unamortized cost of $1,142 at December 31, 2014. The cost of these shares is expected to be recognized over a weighted-average period of 1.7 years.
	The Company recorded stock option compensation expenses of $465, $301, and $232, for 2014, 2013, and 2012, respectively. As of December 31, 2014, there was $982 in total unrecognized stock option compensation expense related to non-vested options. This cost is expected to be recognized over a weighted-average period of 1.58 years.

	The total intrinsic value of options exercised was $5 and $25 during 2014 and 2013, respectively. There were no options exercised in 2012. The weighted-average grant date fair value of non-vested options at December 31, 2014, was $1.45 per share. In 2014 60,000 non-vested options were forfeited.
	The Company uses the Black-Scholes option-pricing model to estimate the fair value of granted options. This model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. However, the Company's stock options have characteristics significantly different from traded options and changes in the subjective input assumptions can materially affect the fair value estimate. Option valuation models such as Black-Scholes require the input of highly subjective assumptions including the expected stock price volatility, which is computed using ten years of actual price activity in the Company’s stock. The Company uses historical data of employee behavior as a basis to estimate the expected life of the options, as well as forfeitures due to employee terminations. The Company also uses its actual dividend yield at the time of the grant, as well as actual U.S. Treasury yields in effect at the time of the grant to estimate the risk-free rate. The following weighted-average assumptions were used to value 276,000 options granted during 2014: risk free interest rate of 2.37%, dividend yield of 1.82%, expected stock volatility of 32%, and expected term to exercise of 7.5 years. The following weighted-average assumptions were used to value 352,000 options granted during 2013: risk free interest rate of 1.28%, dividend yield of 1.67%, expected stock volatility of 30%, and expected term to exercise of 7.5 years. The following weighted-average assumptions were used to value 412,500 options granted during 2012: risk free interest rate of 1.50%, dividend yield of 1.18%, expected stock volatility of 25%, and expected term to exercise of 7.5 years.

Fair Value Disclosures [Abstract]
Financial Instruments With Off Balance Sheet Risk [Text Block]	13. Financial Instruments with Off-Balance-Sheet Risk
	The Company is 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 consist of commitments to extend credit and involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the Consolidated Statements of Financial Condition. The contract amounts reflect the extent of involvement the Company has in particular classes of financial instruments and also represents the Company’s maximum exposure to credit loss.
	Commitments to extend credit are agreements to lend 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 generally require payment of a fee. As some commitments expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates the collateral needed and creditworthiness of each customer on a case by case basis. The Company generally extends credit only on a secured basis. Collateral obtained varies, but consists principally of one- to four-family residences.
	Off-balance sheet financial instruments or obligations that represent exposure to credit risk under commitments to extend credit are summarized in the following table as of the dates indicated:
		December 31
		2014		2013
	Unused commercial lines of credit	$	104,406	$	104,734
	Commercial loans		4,609		1,535
	Standby letters of credit		3,774		3,350
	Real estate loan commitments:
	Fixed rate		33,040		29,158
	Adjustable rate		216,714		141,604
	Unused consumer lines of credit		165,600		168,645
	The Company sells substantially all of its long-term, fixed-rate, one- to four-family loan originations in the secondary market. The Company uses derivative financial instruments to manage interest rate risk associated with these activities. Specifically, the Company enters into interest rate lock commitments (“IRLCs”) with borrowers, which are considered to be derivative financial instruments. The Company manages its exposure to interest rate risk in IRLCs (as well as interest rate risk in its loans held-for-sale) by entering into forward commitments to sell loans to the Fannie Mae. Commitments to sell loans expose the Company to interest rate risk if market rates of interest decrease during the commitment period. Such forward commitments are considered to be derivative financial instruments. These derivatives are not designated as accounting hedges as specified in GAAP. As such, changes in the fair value of the derivative instruments are recognized currently through earnings. As of December 31, 2014 and 2013, net unrealized gains of $84 and $93, respectively, were recognized in net gain on loan sales activities on the derivative instruments specified in the previous paragraph. These amounts were exclusive of net unrealized gains of $117 and $16 on loans held-for-sale as of those dates, respectively, which were also included in net gain on loan sales activities.
	The Company enters into interest rate swap arrangements to manage the interest rate risk exposure associated with specific commercial loan relationships at the time such loans are originated. These interest rate swaps, as well as the embedded derivatives associated with certain of its commercial loan relationships, are derivative financial instruments under GAAP. None of these derivative financial instruments are designated by the Company as accounting hedges as specified in GAAP. As such, the fair market value of the interest rate swaps and embedded derivatives will be carried on the Company’s balance sheet as derivative assets or liabilities, as the case may be, and periodic changes in fair market value of such financial instruments will be recorded through periodic earnings in other non-interest income. During the years ended December 31, 2014 and 2013, net unrealized gains of $1,559 and $32, respectively, and net unrecognized losses of $1,559 and $32, respectively, related to interest rate swaps and embedded derivatives were recorded in other non-interest income.
	The following table summarizes the Company’s derivative financial instruments as of the dates indicated.

Fair Value Disclosures [Abstract]
Fair Value Of Financial Instruments [Text Block]	14. Fair Value Measurements
	Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). The Company utilizes market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated, or generally unobservable. The Company primarily applies the market approach for recurring value measurements and endeavors to utilize the best available information. Accordingly, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. The Company is able to classify fair value measurements based on the observability of those inputs. Accounting guidance establishes a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1), the next highest priority is given to prices based on models, methodologies, and/or management judgments that rely on direct or indirect observable inputs (Level 2), and the lowest priority to prices derived from models, methodologies, and/or management judgments that rely on significant unobservable inputs (Level 3). There were no transfers of assets or liabilities between categories of the fair value hierarchy during the years ended December 31, 2014 and 2013.
	The following methods and assumptions are used by the Company in estimating its fair value disclosures of financial instruments:
	Cash and Cash Equivalents The carrying amounts reported in the statements of financial condition for cash and cash equivalents approximate those assets’ fair values. The Company considers the fair value of cash and cash equivalents to be Level 1 in the fair value hierarchy.
	Mortgage-Related Securities Available-for-Sale and Held-to-Maturity Fair values for these securities are based on price estimates obtained from a third-party independent pricing service. This service utilizes pricing models that vary by asset class and incorporate available trade, bid, ask and other market information of comparable instruments. For structured securities, such as CMOs, the pricing models include cash flow estimates that consider the impact of loan performance data, including, but not limited to, expectations relating to loan prepayments, default rates, and loss severities. Management has reviewed the pricing methodology used by its pricing service to verify that prices are determined in accordance with the fair value guidance specified in GAAP. The Company considers the fair value of mortgage-related securities to be Level 2 in the fair value hierarchy.
	Loans Held-for-Sale The fair value of loans held-for-sale is based on the current market price for securities collateralized by similar loans. The Company considers the fair value of loans held-for-sale to be Level 2 in the fair value hierarchy.
	Loans Receivable Loans receivable are segregated by type such as commercial and industrial loans, commercial real estate mortgage loans, multi-family real estate mortgage loans, one- to four-family mortgage loans, and home equity and other consumer loans. The fair value of each type is calculated by discounting scheduled cash flows through the expected maturity of the loans using estimated market discount rates that reflect the credit and interest rate risk inherent in the loan type. The estimated maturity is based on the Company’s historical experience with prepayments for each loan classification, modified, as required, by an estimate of the effect of current economic and lending conditions. The Company considers the fair value of loans receivable to be Level 3 in the fair value hierarchy.
	Mortgage Servicing Rights The Company has calculated the fair market value of mortgage servicing rights for those loans that are sold with servicing rights retained. For valuation purposes, loans are stratified by product type and, within product type, by interest rates. The fair value of mortgage servicing rights is based upon the present value of estimated future cash flows using current market assumptions for prepayments, servicing cost and other factors. The Company considers the fair value of mortgage servicing rights to be Level 3 in the fair value hierarchy.
	The following table summarizes the significant inputs utilized by the Company to estimate the fair value of its MSRs as of December 31, 2014:
		Weighted-			Range
		Average
	Loan size	$	119			$2-$412
	Contractual interest rate		3.78	%		2.00%-7.15%
	Constant prepayment rate (“CPR”)		10.61	%		5.69%-22.67%
	Remaining maturity in months		229			5-480
	Servicing fee		0.25	%		–
	Annual servicing cost per loan (not in thousands)	$	60			–
	Annual ancillary income per loan (not in thousands)	$	30			–
	Discount rate		9.55	%		9.50%-11.25%
	MSR pools with an amortized cost basis greater than fair value are carried at fair value in the Company’s financial statements. There were no pools determined to be impaired at December 31, 2014, and as such there was no valuation allowance at December 31, 2014. In 2014 the Company recorded a gain of $1, which was equal to the change in the valuation allowance for that period. Pools determined to be impaired at December 31, 2013, had an amortized cost basis of $10 and a fair value of $9 as of that date. Accordingly, the Company recorded a valuation allowance of $1 as of December 31, 2013, as well as a corresponding gain of $2,395 during the twelve month period then ended, which was equal to the change in the valuation allowance during that period.
	Federal Home Loan Bank Stock FHLB of Chicago stock is carried at cost, which is its redeemable (fair) value, since the market for this stock is restricted. The Company considers the fair value of FHLB of Chicago stock to be Level 2 in the fair value hierarchy.
	Accrued Interest Receivable and Payable The carrying values of accrued interest receivable and payable approximate their fair value. The Company considers the accrued interest receivable and payable to be Level 2 in the fair value hierarchy.
	Deposit Liabilities and Advance Payments by Borrowers for Taxes and Insurance Fair value for demand deposits equal book value. The Company considers the fair value of demand deposits to be Level 2 in the fair value hierarchy. Fair values for certificate of deposits are estimated using a discounted cash flow calculation that applies current market borrowing interest rates to a schedule of aggregated expected monthly maturities on deposits. The Company considers the fair value of certificates of deposit to be Level 3 in the fair value hierarchy. The advance payments by borrowers for taxes and insurance are equal to their carrying amounts at the reporting date. The Company considers the fair value of advance payments by borrowers to be Level 2 in the fair value hierarchy.
	Borrowings The fair value of long-term borrowings is estimated using discounted cash flow calculations with the discount rates equal to interest rates currently being offered for borrowings with similar terms and maturities. The carrying value on short-term borrowings approximates fair value. The Company considers the fair value of borrowings to be Level 2 in the fair value hierarchy.
	Off-Balance Sheet Financial Instruments Off-balance sheet financial instruments consist of commitments to extend credit, IRLCs, forward commitments to sell loans, interest rate swaps, and embedded derivatives related to certain commercial loan relationships. Commitments to extend credit that are not IRLCs generally carry variable rates of interest. As such, the fair value of these instruments is not material. The Company considers the fair value of these instruments to be Level 2 in the fair value hierarchy. The carrying value of IRLCs, forward commitments to sell loans, interest rate swaps and embedded derivatives is equal to their fair value. For IRLCs and forward commitments, the fair value is the difference between the current market prices for securities collateralized by similar loans and the notional amounts of the IRLCs and forward commitments. The fair value of the Company’s interest rate swaps and embedded derivatives is determined using discounted cash flow analysis on the expected cash flows of each derivative and also includes a nonperformance or credit risk component. The Company considers the fair value of IRLCs, forward commitments to sell loans, interest rate swaps, and embedded derivatives to be Level 2 in the fair value hierarchy.
	The carrying values and fair values of the Company’s financial instruments are presented in the following table as of the dates indicated.
		December 31, 2014					December 31, 2013

	Total		–		$	448,394		–	$	448,394
	Impaired Loans For non-accrual loans greater than an established threshold and individually evaluated for impairment and all renegotiated loans, impairment is measured based on: (i) the fair value of the loan or the fair value of the collateral less estimated selling costs (collectively the “collateral value method”) or (ii) the present value of the estimated cash flows discounted at the loan’s original effective interest rate (the “discounted cash flow method”). The resulting valuation allowance, if any, is a component of the allowance for loan losses. The discounted cash flow method is a fair value measure. For the collateral value method, the Company generally obtains appraisals on a periodic basis to support the fair value of collateral underlying the loans. Appraisals are performed by independent certified and/or licensed appraisers that have been reviewed by the Company and incorporate information such as recent sales prices for comparable properties, costs of construction, and net operating income of the property or business. Selling costs are generally estimated at 10%. Appraised values may be further discounted based on management judgment regarding changes in market conditions and other factors since the time of the appraisal. A significant unobservable input in using net operating income to estimate fair value is the capitalization rate. At December 31, 2014, the range of capitalization rates utilized to determine the fair value of the underlying collateral on certain loans was 6% to 12%. The Company considers these fair values to be Level 3 in the fair value hierarchy. For those loans individually evaluated for impairment using the collateral value method, a valuation allowance of $904 was recorded for loans with a recorded investment of $45,425 at December 31, 2014. These amounts were $1,000 and $49,063 at December 31, 2013, respectively. Provision for loan losses related to these loans was $316 and $380 in 2014 and 2013, respectively.
	Foreclosed Properties Foreclosed properties acquired through, or in lieu of, loan foreclosure are recorded at the lower of cost or fair value less estimated costs to sell. In determining fair value, the Company generally obtains appraisals to support the fair value of foreclosed properties, as described in the previous paragraph. In certain instances, the Company may also use the selling list price, less estimated costs to sell, as the fair value of foreclosed properties. In such instances, the list price is generally less than the appraised value. The Company considers these fair values to be Level 3 in the fair value hierarchy. As of December 31, 2014, $4,311 in foreclosed properties were valued at collateral value compared to $6,612 at December 31, 2013. Losses of $856 and $1,672 related to these foreclosed properties valued at collateral value were recorded during the twelve months ended December 31, 2014 and 2013, respectively.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation, Policy [Policy Text Block]	Principles of Consolidation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States. The consolidated financial statements include the accounts and transactions of the Company and its wholly-owned subsidiaries. The Bank has the following active wholly-owned subsidiaries: BancMutual Financial & Investment Services, Inc., and MC Development Ltd. MC Development Ltd. owns a 50% interest in Arrowood Development LLC, which is a variable interest entity and is consolidated into the financial statements. All intercompany accounts and transactions have been eliminated in consolidation.
	In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the statement of financial condition and revenues and expenses for the period. Actual results could differ from those estimates.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents The Company considers interest-bearing deposits in banks and federal funds sold that have original maturities of three months or less to be cash equivalents. Under Regulation D, the Bank is required to maintain cash and reserve balances with the Federal Reserve Bank of Chicago. The average amount of required reserve balances for the years ended December 31, 2014 and 2013, was $14,525 and $12,921, respectively.
Federal Home Loan Bank Advances [Policy Text Block]	Federal Home Loan Bank Stock Stock of the Federal Home Loan Bank of Chicago (“FHLB of Chicago”) is owned due to membership requirements and is carried at cost, which is its redemption value, and is included in other assets. FHLB stock is periodically reviewed for impairment based on management’s assessment of the ultimate recoverability of the investment rather than temporary declines in its estimated fair value.
Marketable Securities, Available-for-sale Securities, Policy [Policy Text Block]	Securities Available-for-Sale and Held-to-Maturity Available-for-sale securities are stated at fair value, with the unrealized gains and losses, net of tax, reported as a separate component of accumulated other comprehensive loss in shareholders’ equity. Held-to-maturity securities are stated at amortized cost.
	The amortized cost of securities classified as available-for-sale or held-to-maturity is adjusted for amortization of premiums and accretion of discounts to maturity, or in the case of mortgage-related securities, over the estimated life of the securities. Such accretion or amortization is included in interest income from investments. Interest and dividends are included in interest income from investments. Realized gains and losses and declines in value judged to be other-than-temporary are included in net gain or loss on sales of securities and are based on the specific identification method.
	Impairment of available-for-sale and held-to-maturity securities is evaluated considering numerous factors, and their relative significance varies case-by-case. Factors considered include the length of time and extent to which the market value has been less than cost; the financial condition and near-term prospects of the issuer of a security; and the Company’s intent and/or likely need to sell the security before its anticipated recovery in fair value. Further, if the Company does not expect to recover the entire amortized cost of the security (i.e., a credit loss is expected), the Company will be unable to assert that it will recover its cost basis even if it does not intend to sell the security. If, based upon an analysis of each of these factors, it is determined that the impairment is other-than-temporary, the carrying value of the security is written down through earnings by the amount of the expected credit loss.
Finance, Loan and Lease Receivables, Held-for-sale, Policy [Policy Text Block]	Loans Receivable and Loans Held-for-Sale Loans receivable are recorded at cost, net of undisbursed loan proceeds, allowance for loan losses, unamortized deferred fees and costs, and unamortized purchase premiums or discounts, if any. Loan origination and commitment fees and certain direct loan origination costs are deferred and amortized as an adjustment of loan yield. Purchase premiums and discounts are also amortized as an adjustment of yield.
	Loans held-for-sale, which generally consists of recently originated fixed-rate residential mortgage loans, are recorded at market value determined on an individual loan basis. Fees received from the borrower are deferred and recorded as an adjustment of the carrying value.
Revenue Recognition, Interest [Policy Text Block]	Accrued Interest on Loans Interest on loans receivable is accrued and credited to income as earned. The Company measures the past due status of a loan by the number of days that have elapsed since the borrower has failed to make a contractual loan payment. Accrual of interest is generally discontinued when either (i) reasonable doubt exists as to the full, timely collection of interest or principal or (ii) when a loan becomes past due by more than 90 days. At that time, the loan is considered impaired and any accrued but uncollected interest is reversed. Additional interest income is recorded only to the extent that payments are received, collection of the principal is reasonably assured, and/or the net recorded investment in the loan is deemed to be collectible. Loans are generally restored to accrual status when the obligation is brought to a current status by the borrower.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Allowance for Loan Losses and Impaired Loans The Company classifies its loan portfolio into six segments for purposes of determining its allowance for loan losses: commercial and industrial, commercial real estate, multi-family real estate, construction and development, one- to four-family real estate, and home equity and other consumer. This segmentation is based on the nature of the loan collateral and the purpose of the loan, which in the judgment of management are the primary risk characteristics that determine the allowance for loan loss. Loans in the commercial and industrial segment are typically secured by equipment, inventory, receivables, other business assets, and in some instances, business and personal real estate, or may be unsecured. Loans in the commercial real estate, multi-family real estate, and one- to four-family real estate segments are secured principally by real estate. The commercial real estate segment consists of non-residential loans secured by office, retail/wholesale, industrial/warehouse, and other properties. The construction and development segment consists of loans secured by commercial real estate, multi-family, and developed and undeveloped land. Loans in the home equity and other consumer segment may be secured by real estate, personal property, or may be unsecured.
	The allowance for loan losses for each segment is maintained at a level believed adequate by management to absorb probable losses inherent in each segment and is based on factors such as the size and current risk characteristics of the segments, an assessment of individual problem loans and pools of homogenous loans within the segments, and actual loss, delinquency, and/or risk rating experience within the segments. The Company also considers current economic conditions and/or events in specific industries and geographical areas, including unemployment levels, trends in real estate values, peer comparisons, and other pertinent factors, to include regulatory guidance. Finally, as appropriate, the Company also considers individual borrower circumstances and the condition and fair value of the loan collateral, if any.
	The allowance for loan losses for each segment is determined using a combined approach. Individual loans in the segments that have been identified as impaired are analyzed individually to determine an appropriate allowance for loan loss. In addition, the allowance for loan losses for each segment is augmented using a homogenous pool approach for loans in each segment that are current and/or have not been individually identified as impaired loans. The homogenous approach utilizes loss rates that are developed by management using the qualitative factors and other considerations outlined in the previous paragraph.
	Loans are considered impaired when they are identified as such by the Company’s internal risk rating and loss evaluation process or when contractually past due 90 days or more with respect to interest or principal. Factors that indicate impairment include, but are not limited to, deterioration in a borrower’s financial condition, performance, or outlook, decline in the condition, performance, or fair value of the collateral for the loan (if any), payment or other default on the loan, and adverse economic or market developments in the borrower’s region or business segment. Accrual of interest is typically discontinued on impaired loans, although from time-to-time the Company may continue to accrue interest and/or recognize interest income on impaired loans when payments are being received and, in the judgment of management, collection of the principal is reasonably assured and/or the net recorded investment in the loan is deemed to be collectible.
	The Company has various policies and procedures in place to monitor its exposure to credit risk including, but not limited to, a formal risk rating process, periodic loan delinquency reporting, periodic loan file reviews, financial updates from and visits to borrowers, and established past-due loan collection procedures. The Company formally evaluates its allowance for loan losses on a quarterly basis or more often as deemed necessary. A provision for loan loss is charged to operations based on this periodic evaluation. Actual loan losses are charged off against the allowance for loan losses, while recoveries of amounts previously charged off are credited to the allowance.
	Determination of the allowance is inherently subjective as it requires significant estimates, including the amounts and timing of expected future cash flows on loans, the fair value of underlying collateral (if any), estimated losses on pools of homogeneous loans based on historical loss experience, changes in risk characteristics of the loan portfolio, and consideration of current economic trends, all of which may be susceptible to significant change.
Mortgage Servicing Rights Policy [Policy Text Block]	Mortgage Servicing Rights Mortgage servicing rights are recorded as an asset when loans are sold with servicing rights retained. The total cost of loans sold is allocated between the loan balance and their servicing asset based on their relative fair values. The capitalized value of mortgage servicing rights is amortized in proportion to, and over the period of, estimated net future servicing revenue. Mortgage servicing rights are carried at the lower of the initial carrying value, adjusted for amortization, or estimated fair value. The carrying values are periodically evaluated for impairment. For purposes of measuring impairment, the servicing rights are stratified into pools based on term and interest rate. Impairment represents the excess of the remaining capitalized cost of a stratified pool over its fair value, and is recorded through a valuation allowance. The fair value of each servicing rights pool is calculated based on the present value of estimated future cash flows using a discount rate, given current market conditions. Estimates of fair value include assumptions about prepayment speeds, interest rates and other factors which are subject to change over time. Changes in these underlying assumptions could cause the fair value of mortgage servicing rights, and the related valuation allowance, if any, to change significantly in the future.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Derivative Financial Instruments In connection with its mortgage banking activities, the Company enters into loan commitments to fund residential mortgage loans at specified interest rates and within specified periods of time, generally up to 60 days from the time of rate lock. A loan commitment whose loan arising from exercise of the loan commitment will be held for sale upon funding is a derivative instrument, which must be recognized at fair value on the consolidated balance sheet in other assets and other liabilities with changes in its value recorded in income from mortgage banking operations.
	In determining the fair value of its derivative loan commitments for economic purposes, the Company considers the value that would be generated when the loan arising from exercise of the loan commitment is sold in the secondary mortgage market. That value includes the price that the loan is expected to be sold for in the secondary mortgage market.
	The Company enters into interest rate swap arrangements to manage the interest rate risk exposure associated with specific commercial loan relationships at the time such loans are originated. These interest rate swaps, as well as the embedded derivatives associated with certain of the Company’s commercial loan relationships, are derivative instruments under GAAP. The Company has not designated any of these derivative instruments as accounting hedges as specified in GAAP. As such, the fair market value of interest rate swaps and embedded derivatives are included in the Company’s assets or liabilities, as the case may be, and periodic changes in fair market value of such derivative instruments are recorded through periodic earnings in other non-interest income.
Finance, Loan and Lease Receivables, Held for Investments, Foreclosed Assets Policy [Policy Text Block]	Foreclosed Properties and Repossessed Assets Foreclosed properties acquired through, or in lieu of, loan foreclosure are recorded at the lower of cost or fair value less estimated costs to sell. Costs related to the development and improvement of property are capitalized provided such costs do not result in a carrying value in excess of the property’s fair value less estimated costs to sell, in which case such costs are expensed. Costs related to holding the property are expensed. Gains and losses on sales are recognized based on the carrying value upon closing of the sale.
Property, Plant and Equipment, Policy [Policy Text Block]	Premises and Equipment Land, buildings, leasehold improvements and equipment are carried at amortized cost. Buildings and equipment are depreciated over their estimated useful lives (office buildings 30 to 45 years and furniture and equipment 3 to 10 years) using the straight-line method. Leasehold improvements are amortized over the shorter of their useful lives or expected lease terms. The Company reviews buildings, leasehold improvements and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Impairment exists when the estimated undiscounted cash flows for the property are less than its carrying value. If identified, an impairment loss is recognized through a charge to earnings based on the fair value of the property.
Life Insurance Policies Policy [Policy Text Block]	Life Insurance Policies Investments in life insurance policies owned by the Company are carried at the amount that could be realized under the insurance contract if the Company cashed them in on the respective dates.
Income Tax, Policy [Policy Text Block]	Income Taxes The Company files consolidated federal and combined state income tax returns. A deferred tax asset or liability is determined based on the enacted tax rates that will be in effect when the differences between the financial statement carrying amounts and tax basis of existing assets and liabilities are expected to be reported in the Company’s income tax returns. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date of the change. A valuation allowance is provided for any deferred tax asset for which it is more likely than not that the asset will not be realized. Changes in valuation allowances are recorded as a component of income taxes.
	In 2013 the IRS issued final tangible property regulations to be effective for the Company’s 2014 federal income tax return. The Company’s adoption of these rules is not expected to have a significant impact on the Company’s financial condition or results of operations.
Earnings Per Share, Policy [Policy Text Block]	Earnings (Loss) Per Share Basic and diluted earnings (loss) per share (“EPS”) are computed by dividing net income by the weighted-average number of common shares outstanding for the period. Vested shares of restricted stock which have been awarded under provisions of the Company's 2004 and 2014 Stock Incentive Plans are also considered outstanding for basic EPS. Non-vested restricted stock and stock option shares are considered dilutive potential common shares and are included in the weighted-average number of shares outstanding for diluted EPS.
Pension and Other Postretirement Plans, Pensions, Policy [Policy Text Block]	Pension Costs The Company has a qualifying defined benefit plan and a supplemental defined benefit plan. As appropriate, the net periodic pension cost of these plans consists of the expected cost of benefits earned by employees during the current period and an interest cost on the projected benefit obligation, reduced by the expected earnings on assets held by the plans, amortization of prior service cost, and amortization of recognized actuarial gains and losses over the estimated future service period of existing plan participants. Effective January 1, 2014, the Company froze the benefits of participants in the qualified defined benefit pension plan that had less than 20 years of service. This change also resulted in the future benefits under the Company’s supplemental defined benefit pension plan being effectively frozen.
	The Company also has a defined contribution plan. The costs associated with the defined contribution plan consist of a predetermined percentage of individual participant compensation, as well as the cost of discretionary contributions determined by the Company’s board of directors.
Segment Reporting, Policy [Policy Text Block]	Segment Information The Company has determined that it has one reportable segment—community banking. The Company offers a range of financial products and services to external customers, including: accepting deposits from the general public, originating secured and unsecured loans to commercial and retail borrowers, and marketing annuities and other insurance products.
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Changes In 2011 the Financial Accounting Standards Board (“FASB”) issued new accounting guidelines related to the disclosure of both gross information and net information about instruments eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting agreement. The guidance was effective for interim and fiscal periods beginning on or after January 1, 2013, which for the Company was the first quarter of 2013. The Company's adoption of these new accounting guidelines did not have a material impact on its results of operations or financial condition. However, the guidelines do affect how matters may be disclosed in the financial statements.
	In 2012 the FASB issued new accounting guidance related to (i) testing indefinite-lived intangible assets for impairment and (ii) subsequent measurement of an indemnification asset recognized in a government-assisted acquisition of a financial institution. Item (i) was effective for years beginning after September 15, 2012, which was the first quarter of 2013 for the Company. Item (ii) was effective for fiscal years beginning on or after December 15, 2012, which was the first quarter of 2013 for the Company. The Company’s adoption of these new guidelines did not have a material impact in its results of operations or financial condition.
	In 2013 the FASB issued new accounting guidance relating to (i) the reporting of reclassifications out of accumulated other comprehensive income or loss; and (ii) the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date. Item (i) was effective for fiscal years beginning after December 15, 2012, which was the first quarter of 2013 for the Company. The adoption of this item did not have an effect on the Company’s results of operations or financial condition. Item (ii) was effective for fiscal years beginning after December 15, 2013, which was the first quarter of 2014 for the Company. Adoption of this item did not have a material impact on the Company’s results of operations or financial condition.
	In 2013 the FASB issued new accounting guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carry forward, a similar tax loss, or a tax credit carry forward exists. The guidance was effective for fiscal years and interim periods beginning after December 15, 2013, which was the first quarter of 2014 for the Company. Adoption of this item did not have a material impact on the Company’s results of operations or financial condition.
	In the first quarter of 2014 the FASB issued new accounting guidance related to troubled debt restructurings by creditors to clarify when an in-substance repossession or foreclosure occurs as satisfaction of a consumer mortgage loan. Although the new guidance is effective for fiscal years beginning after December 15, 2014, which would be the first quarter of 2015 for the Company, early adoption of the new guidance is permitted. Accordingly, the Company adopted the new guidance in the first quarter of 2014 using a prospective transition method. Adoption of this new guidance did not have a material impact on the Company’s results of operations or financial condition. However, it did affect how certain matters are disclosed in the financial statements.
	In the second quarter of 2014 the FASB issued new accounting guidance related to the recognition of revenue from contracts with customers. The guidance is effective for fiscal years and interim periods beginning after December 15, 2016, which will be the first quarter of 2017 for the Company. The Company’s adoption of this item is not expected to have a material impact on its results of operations or financial condition.
	In the third quarter of 2014 the FASB issued new accounting guidance related to the classification and measurement of certain government-guaranteed mortgages upon foreclosure. The guidance is effective for fiscal years and interim periods beginning after December 15, 2014, which will be the first quarter of 2015 for the Company. The Company’s adoption of this item is not expected to have a material impact on its results of operations or financial condition.
Reclassification, Policy [Policy Text Block]	Reclassifications Certain components of non-interest income in 2013 and 2012 were reclassified to conform to the 2014 presentation format. For the years ended December 31, 2013 and 2012, $6,769 and $6,903 that had been previously reported as “service charges on deposits” in such periods, respectively, were renamed as “deposit-related fees and charges.” These amounts were combined with $5,427 and $5,134 of other fee income from deposit customers that had been previously included in “other non-interest income” in those periods, respectively. Also, for the same years, respectively, net loan servicing revenue of $2,471 and $(2,606) was reclassified from “loan-related fees and servicing revenue, net” and was combined with $4,405 and $13,206 in “gain on loan sales activities, net” and the aggregate amount reported as “mortgage banking revenue, net.” Finally, $844 and $695 in 2013 and 2012, respectively, that was previously included in “loan-related fees and servicing revenue, net,” was reclassified to “other non-interest income.”
