Management evaluates each of these loans in accordance with generally accepted accounting principles to determine whether they should be reported as troubled debt restructurings. The Company offers a variety of modifications to borrowers. The modification categories offered can generally be described in the following categories: · Rate Modification - A modification in which the interest rate is changed. · Term Modification - A modification in which the maturity date, timing of payments, or frequency of payments is changed. · Interest Only Modification – A modification in which the loan is converted to interest only payments for a period of time. · Payment Modification – A modification in which the dollar amount of the payment is changed, other than an interest only modification described above. · Combination Modification – Any other type of modification, including the use of multiple categories above.

The Bank’s policy generally refers to nine months of payment performance as sufficient to warrant a return to accrual status. Troubled debt restructurings are classified as impaired loans when modified, and fair value calculations are performed to determine the specific reserves required in the allowance for loan losses related to these loans. Troubled debt restructurings can be removed from such status and returned to non-impaired status in years subsequent to restructure if the interest rate charged at restructure was greater than or equal to the rate charged for a new extension of credit with comparable risk and if the loan is performing and there is no available information to indicate that performance will not continue.

Troubled debt restructuring defaults can result in a higher allowance for loan losses and a corresponding higher provision for loan losses because defaults generally negatively impact the timing of and expected collections from these impaired loans. Impaired loans, which include troubled debt restructurings, are evaluated for specific additions to the allowance for loan losses by subtracting the recorded investment in these impaired loans from their fair values. Fair value is generally determined by the present value of future cash flows, collateral value, or liquidation value. Defaults generally reduce the present value of the future cash flows and can negatively impact the collateral values if declining real estate values are impacting the sale of collateral. Loans secured by one-to-four family residential properties with unpaid principal balances of $ 700,000

Fair Value Measurements [Abstract]
Fair Value, Measurement Inputs, Disclosure [Text Block]	Note L – Fair value measurements The Company has adopted the accounting standards within FASB Accounting Standards Codification (ASC) 820 “ Fair Value Measurements and Disclosures When measuring fair value, valuation techniques should be appropriate in the circumstances and consistently applied. A hierarchy is used to prioritize valuation inputs into the following three levels to determine fair value: Level 1 – quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 – observable inputs other than the quoted prices included in Level 1. Level 3 – unobservable inputs. Fair Value on a Recurring Basis. The Company measures certain assets at fair value on a recurring basis and the following is a general description of the methods used to value such assets. Investment Securities Available-for-Sale Investment securities available-for-sale are recorded at fair value. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss assumptions. Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange, U.S. Treasury securities and certain corporate bonds that are traded by dealers or brokers in active over-the-counter markets and money market funds. Level 2 securities include mortgage-backed securities issued by government sponsored entities, municipal bonds and most corporate debt securities. Securities classified as Level 3 include asset-backed securities and corporate debt securities in less liquid markets. Loans Held for Sale The Company opted to account for loans held for sale at fair value which is measured based on what secondary markets are currently offering for portfolios with similar characteristics or based on sales commitments actually made to investors. As such, the Company classifies loans subject to recurring fair value adjustments as Level 2 valuation. Interest Rate Lock Commitments The mortgage banking division of the Company sells its residential mortgage loans held for sale on a forward best efforts basis at a fixed price or on a mandatory basis by entering into forward sale mortgage-backed securities transactions at approximately the same time that fixed rate commitments are given to borrowers. The value of the estimated interest rate lock commitments given to borrowers were marked to market through the income statement during 2015. The significant unobservable input used in the Level 3 fair value measurement of the Company’s Interest Rate Lock Commitments (IRLCs) on loans held for sale is the closing ratio, which represents the percentage of loans currently in a lock position which management estimates will ultimately close. The closing ratio is largely dependent on loan processing stages and the change in prevailing interest rates from the time of the rate lock. The closing ratio is computed by management using historical data. The fair value of interest rate lock commitments is based on servicing rate premium, origination income net of origination costs, fall out rates and changes in loan pricing due to delays in meeting commitment closing dates. The Company classifies interest rate lock commitments as Level 3. Gain or loss on interest rate lock commitments for the period is included in mortgage banking income of non-interest income on the Consolidated Statements of Income. Interest Rate Lock Commitments Level 3 Fair Value Fair Value (in thousands) Balance, December 31, 2014 and 2013 $ - $ - Gains, net of losses, included in mortgage banking income 716 - Transfers in and out - - Balance, September 30, 2015 and 2014 $ 716 $ - Unrealized gains (losses) on forward sale mortgage-backed securities The mortgage banking division of the Company resumed selling a portion of its loans on a mandatory basis in 2015 and hedging the related loans and forward commitments to borrowers by entering into forward sale mortgage-backed securities transactions at approximately the same time that fixed rate commitments are given to borrowers. The forward sale mortgage-backed securities are purchased or closed when the related loans sales are consummated. The unrealized gains or losses on forward sale mortgage-backed securities are included in mortgage banking income to properly match the income from interest rate commitments noted above. The Company classifies unrealized gains (losses) on forward sale mortgage-backed securities as Level 1 since end of the day bid prices in the active mortgage backed securities market are used to determine the unrealized losses. Unrealized gains are shown as other assets and unrealized losses are shown as other liabilities on the consolidated balance sheet.

The Company measures certain assets at fair value on a non-recurring basis and the following is a general description of the methods used to value such assets. Impaired Loans The Company does not record loans at fair value on a recurring basis. However, from time to time, a loan is considered impaired and an allowance for loan losses is established. Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. Impaired loans are recorded at fair value less estimated selling costs. Once a loan is identified as individually impaired, the Company measures impairment. Fair values of impaired loans are generally estimated using one of several methods, including collateral value, liquidation value, discounted cash flows and, in rare cases, the market value of the note. Those impaired loans not requiring an allowance represent loans for which the net present value of the expected cash flows or fair value of the collateral less costs to sell exceed the recorded investments in such loans. At September 30, 2015 and December 31, 2014, a majority of the total impaired loans were evaluated based on the fair value of the collateral. When the fair value of the collateral is based on an executed sales contract with an independent third party, the Company records the impaired loans as nonrecurring Level 1. If the collateral is based on another observable market price or a current appraised value, the Company records the impaired loans as nonrecurring Level 2. When an appraised value is not available or the Company determines the fair value of the collateral is further impaired below the appraised value and there is no observable market price, the Company records the impaired loan as nonrecurring Level 3. Impaired loans can also be evaluated for impairment using the present value of expected future cash flows discounted at the loan’s original effective interest rate. Impaired loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly. Other Real Estate Owned and Repossessed Assets Properties acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value less costs to sell at the date of foreclosure. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying value or the new fair value less estimated selling costs. Fair value is generally based upon current appraisals, comparable sales, and other estimates of value obtained principally from independent sources, adjusted for selling costs. When the fair value of the collateral is based on an observable market price or a current appraised value, the Company records the asset as nonrecurring Level 2. However, the Company also considers other factors or recent developments which could result in adjustments to the collateral value estimates indicated in the appraisals such as changes in absorption rates or market conditions from the time of valuation. In situations where an appraisal less estimated selling costs is used to determine fair value, management adjustments are significant to the fair value measurements, or other means are used to estimate fair value in the absence of an appraisal, the Company records the impaired loan as nonrecurring Level 3 within the valuation hierarchy. Assets measured at fair value on a non-recurring basis at September 30, 2015 and December 31, 2014 are summarized below: Assets Measured at Fair Value Measured Using Description Fair Value Level 1 Level 2 Level 3 (in thousands) At September 30, 2015: Impaired loans $ 16,635 $ - $ - $ 16,635 Other real estate owned 5,073 - - 5,073 At December 31, 2014: Impaired loans $ 17,838 $ - $ - $ 17,838 Other real estate owned 5,610 - - 5,610 For Level 3 assets and liabilities measured at fair value on a recurring or non-recurring basis as of September 30, 2015, the significant unobservable inputs used in the fair value measurements were as follows: Significant Significant Valuation Unobservable Unobservable Description Fair Value Technique Inputs Input Value ($ in thousands) At September 30, 2015: Impaired loans $ 16,635 Discounted appraisals Collateral discounts 8.00%-10.00% Discounted cash flows Cash flow estimates/ 0% - 100% / discounted rates original note rate Other real estate owned 5,073 Discounted appraisals Collateral discounts 8.00%-10.00% Net derivative assets /liabilities: Interest rate lock commitments 716 Pricing models Loan closing ratios 25% - 100% 76% Average At December 31, 2014: Impaired loans $ 17,838 Discounted appraisals Collateral discounts 8.00%-10.00% Discounted cash flows Cash flow estimates/ 0% - 100% / discounted rates original note rate Other real estate owned 5,610 Discounted appraisals Collateral discounts 8.00%-10.00% Fair Value of items not valued as such. The Company measures certain financial assets and liabilities at fair value for disclosure purposes only. The assumptions used in estimating the fair value of these financial instruments are detailed below: Securities Held to Maturity The fair values of securities held to maturity are recorded on a non-recurring basis when an impairment in value that is deemed to be other than temporary occurs. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss assumptions. At September 30, 2015, there were no fair value adjustments related to $ 14,718,000 Net non-impaired loans held for investment : For variable rate loans, fair values are based on carrying values. Fixed rate commercial, other installment, and certain real estate mortgage loans are valued using discounted cash flows. The discount rates used to determine the present value of these loans are based on interest rates currently being charged by the Company on comparable loans as to credit risk and term. Time deposits : Discounted cash flows have been used to value fixed rate and variable rate term deposits. The discount rate used is based on interest rates currently being offered by the Company on comparable deposits as to amount and term.

Derivatives and Financial Instruments [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	Note M – Derivatives and financial instruments A derivative is a financial instrument or arrangement that derives its cash flows and value by reference to an underlying instrument, index or referenced interest rate. These instruments are designed to hedge exposures to interest rate risk or for speculative purposes. The Company increased its use of derivatives related to hedging interest rate lock commitments during the second quarter of 2015 as noted below. Accounting guidance requires an entity to recognize all derivatives as either assets or liabilities in the balance sheet, and measure those instruments at fair value. Changes in the fair value of those derivatives are reported in current earnings or other comprehensive income depending on the purpose for which the derivative is held and whether the derivative qualifies for hedge accounting. The Company currently sells mortgage loans on a best efforts basis and a mandatory basis in order to minimize the impact of changing interest rates on the value of fixed loan commitments given to borrowers. Optional commitments to sell mortgage loans are consummated at approximately the same time that optional commitments are given to borrowers to originate the loans under best efforts sales. Mandatory loan sales are generally made after loans are closed; the related fixed rate loan commitments granted to borrowers when they lock in their loan rates are hedged by selling mortgage-backed securities on a forward basis. The forward sold mortgage-backed securities are later purchased to close the hedge once the mandatory sales are consummated. The Company resumed selling loans on a mandatory basis and re-instituted hedging mortgage loan rate lock commitments during the second quarter of 2015.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	Note N – Impact of recently adopted accounting standards On January 15, 2014, the FASB issued ASU 2014-01, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects (a consensus of the FASB Emerging Issues Task Force) 3 1.2 In January, 2015, the FASB issued ASU No. 2015-01, Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items. In June 2014, the FASB issued guidance which makes limited amendments to the guidance on accounting for certain repurchase agreements. The new guidance (1) requires entities to account for repurchase-to-maturity transactions as secured borrowings (rather than as sales with forward repurchase agreements), (2) eliminates accounting guidance on linked repurchase financing transactions, and (3) expands disclosure requirements related to certain transfers of financial assets that are accounted for as sales and certain transfers (specifically, repos, securities lending transactions, and repurchase-to-maturity transactions) accounted for as secured borrowings. The amendments were effective for the Company for the reporting period beginning with the first quarter of 2015. The amendments did not have a material effect on the Company’s consolidated financial statements. In May 2014, the FASB issued guidance to change the recognition of revenue from contracts with customers. The core principle of the new guidance is that an entity should recognize revenue to reflect the transfer of goods and services to customers in an amount equal to the consideration the entity receives or expects to receive. The guidance will be effective for the Company for reporting periods beginning after December 15, 2017 . In January 2014, the FASB amended the Receivables topic of the Accounting Standards Codification. The amendments are intended to resolve diversity in practice with respect to when a creditor should reclassify a collateralized consumer mortgage loan to other real estate owned (OREO). In addition, the amendments require a creditor to reclassify a collateralized consumer mortgage loan to OREO upon obtaining legal title to the real estate collateral, or the borrower voluntarily conveying all interest in the real estate property to the lender to satisfy the loan through a deed in lieu of foreclosure or similar legal agreement. The amendments will be effective for the Company for annual periods, and interim periods within those annual periods beginning after December 15, 2014 , In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis Consolidation • Limited partnerships will be considered variable interest entities (VIEs), unless the limited partners have either substantive kick-out or participating rights. • The amendments change the effect that fees paid to a decision maker or service provider have on the consolidation analysis. Specifically, it is less likely that the fees themselves will be considered a variable interest, that an entity will be a VIE, or that consolidation will result. • The amendments significantly modify how variable interests held by a reporting entity’s related parties or de facto agents affect its consolidation conclusion. • For entities other than limited partnerships, the amendments clarify how to determine whether the equity holders (as a group) have power over the entity (this will most likely result in a change to current practice). The clarification could affect whether the entity is a VIE. • The deferral of ASU 2009-17, Improvements to Financial Reporting by Enterprises Involved with Variable Interest Entities The amendments are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015 and are not expected to have a material effect on the Company’s consolidated financial statements. The FASB published ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs On April 15, 2015, the FASB issued ASU 2015-05, Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement ⋅ The customer has the contractual right to take possession of the software at any time during the hosting period without significant penalty. ⋅ It is feasible for the customer to either run the software on its own hardware or contract with another party unrelated to the vendor to host the software. For public business entities, the amendments in ASU 2015-05 are effective for interim and annual periods beginning after December 15, 2015. These amendments are not expected to have a material effect on the Company’s consolidated financial statements. Several other accounting standards have been issued or proposed by the FASB or other standards-setting bodies during the periods presented or will be effective subsequent to September 30, 2015. The FASB proposal on Current Expected Credit Loss (“CECL”) is expected to be released in late 2015 or early 2016 and will likely be effective in 2018 or 2019. CECL is expected to require institutions of all sizes to recognize an immediate allowance for expected credit losses on loans and securities which could materially exceed the historical loss rate method currently used to calculate the allowance for loan losses. The Company is currently unable to quantify the impact of CECL on its consolidated financial statements. Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies are not expected to have a material impact on the Company’s consolidated financial position, results of operations or cash flows.

Fair Value, by Balance Sheet Grouping [Table Text Block]	The following table presents the carrying amount, fair value, and placement in the fair value hierarchy of financial instruments at September 30, 2015 and December 31, 2014. This table excludes financial instruments for which the carrying amount approximates fair value. For short-term financial assets such as cash and due from banks and interest-bearing deposits with banks, the carrying amount is a reasonable estimate of fair value due to the relatively short time between the origination of the instrument and its expected realization. For financial liabilities such as non-interest bearing demand deposits, NOW, money market and savings deposits, the carrying amount is a reasonable estimate of fair value due to these products having no stated maturity.
