Accrued interest is reversed through a charge to income when loans are placed on non-accrual status, and future payments on non-accrual loans are generally applied to principal.

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. As of June 30, 2016 there were no available commitments for troubled debt restructurings outstanding.

The Bank’s policy generally refers to six 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.

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.

Fair Value Measurements [Abstract]
Fair Value, Measurement Inputs, Disclosure [Text Block]	Note M – 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. Securities available-for-sale 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. 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 fixed prices or on a mandatory basis by entering into forward sale mortgage-backed securities at approximately the same time as fixed rates are given to borrowers. The value of the estimated interest rate lock commitments (“IRLCs”) given to borrowers were marked to market through the income statement during 2016 and 2015. The significant unobservable input used in the Level 3 fair value measurement of the Company’s 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 IRLCs 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 IRLCs as Level 3. Gain or loss on IRLCs for the period is included in mortgage banking income of non-interest income on the Consolidated Statements of Income. The mortgage banking division resumed reporting IRLCs in the first quarter of 2015 after having suspended recognition in 2014 due to immateriality. Interest Rate Lock Commitments Level 3 Fair Value Fair Value (in thousands) Balance, December 31, 2015 and 2014 $ 393 $ - Gains included in other income 205 613 Transfers in and out - - Balance, June 30, 2016 and 2015 $ 598 $ 613 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 loan 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 IRLCs 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 gains (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 June 30, 2016 and December 31, 2015, 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 effective interest rate. The measurement of impaired loans using future cash flows discounted at the loan’s effective interest rate rather than the market rate of interest is not a fair value measurement and is therefore excluded from fair value disclosure requirements. 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 Measured Using Description Fair Value Level 1 Level 2 Level 3 (in thousands) At June 30, 2016: Impaired loans $ 14,938 $ - $ 4,357 $ 10,581 Other real estate owned 4,212 - - 4,212 $ 19,150 $ - $ 4,357 $ 14,793 At December 31, 2015: Impaired loans $ 13,561 $ - $ 4,400 $ 9,161 Other real estate owned 4,592 - - 4,592 $ 18,153 $ - $ 4,400 $ 13,753 For Level 3 assets and liabilities measured at fair value on a recurring or non-recurring basis as of June 30, 2016, 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 June 30, 2016: Impaired loans $ 10,581 Discounted appraisals Collateral discounts 8.00%-10.00% Discounted cash flows Cash flow estimates/ discounted rates 80% - 100% / Other real estate owned 4,212 Discounted appraisals Collateral discounts 8.00%-10.00% Net derivative assets/liabilities: Interest rate lock commitments 598 Pricing models Loan closing ratios 25% - 100% 78% Average At December 31, 2015: Impaired loans $ 9,161 Discounted appraisals Collateral discounts 8.00%-10.00% Discounted cash flows Cash flow estimates/ discounted rates 80% - 100% / Other real estate owned 4,592 Discounted appraisals Collateral discounts 8.00%-10.00% Net derivative assets/liabilities: Interest rate lock commitments 393 Pricing models Loan closing ratios 25% - 100% 81% Average 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: Bank term deposits : Discounted cash flows have been used to value bank term deposits. The discount rate used is based on interest rates currently being offered by banks accepting institutional term deposits on comparable terms. 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 June 30, 2016 and December 31, 2015, there were no fair value adjustments for other than temporary impairment of securities held-to-maturity. Net non-impaired loans held for investment : For most 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. Trust preferred subordinated debt : The fair value of trust preferred subordinated debt was determined by discounting cash flows using a rate 3% higher than the actual current rate over an estimated remaining term of 11.75 years in 2016 and 12 years in 2015. The trust preferred debt was issued at favorable rates in 2004, and current rates are approximately 3% higher when available. Under the current capital guidelines, the Company’s trust preferred subordinated debt is included in Tier 1 capital.

Derivatives and Financial Instruments [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	Note N – 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 2015. 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 sells residential 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 2015.

New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	Note O – Impact of recently adopted accounting standards The FASB published ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities · Requiring equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income · Requiring public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes · Requiring separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements · Allowing equity investments that do not have readily determinable fair values, to be measured at cost minus impairment (if any), plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer · Eliminating the requirement to disclose the fair value of financial instruments measured at amortized cost for organizations that are not public business entities · Eliminating the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet · Requiring a reporting organization to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk (also referred to as “own credit”) when the organization has elected to measure the liability at fair value in accordance with the fair value option for financial instruments · Requiring separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables) on the balance sheet or in the accompanying notes to the financial statements · Clarifying that a valuation allowance on a deferred tax asset related to available-for-sale securities should be evaluated in combination with the organization’s other deferred tax assets The new guidance is effective for the Company’s 2018 interim and annual statements. These amendments are not expected to have a material effect on the Company’s consolidated financial statements. On March 30, 2016, the FASB issued ASU 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting · Accounting for Income Taxes – All excess tax benefits and tax deficiencies (including tax benefits of dividends on share-based payment awards) should be recognized as income tax expense or benefit in the income statement. The tax effects of exercised or vested awards should be treated as discrete items in the reporting period in which they occur. An entity also should recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period. · Classification of Excess Tax Benefits on the Statement of Cash Flows – Excess tax benefits should be classified along with other income tax cash flows as an operating activity. · Forfeitures – An entity can make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest (current GAAP) or account for forfeitures when they occur. · Minimum Statutory Tax Withholding Requirements – The threshold to qualify for equity classification permits withholding up to the maximum statutory tax rates in the applicable jurisdictions. · Classification of Employee Taxes Paid on the Statement of Cash Flows When an Employer Withholds Shares for Tax Withholding Purposes – Cash paid by an employer when directly withholding shares for tax withholding purposes should be classified as a financing activity. For public business entities, the amendments in this ASU are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods with early adoption permitted in any interim or annual period. These amendments are not expected to have a material effect on the Company’s consolidated financial statements. On March 18, 2016, the FASB issued ASU 2016-08, Principal Versus Agent Considerations—Reporting Revenue Gross Versus Net Revenue from Contracts with Customers On March 15, 2016, the FASB issued ASU 2016-07, Simplifying the Transition to the Equity Method of Accounting On February 25, 2016, the FASB issued the lease accounting standard, ASU 2016-02, Leases On June 16, 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments, as part of its project on financial instruments. The new standard introduces an approach based on expected losses to estimate credit losses on certain types of financial instruments. It also modifies the impairment model for available-for-sale (AFS) debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. The following are some of the key points of the ASU: · For trade and other receivables, held-to-maturity debt securities, loans and other instruments, entities will be required to use a new forward-looking, lifetime “expected loss” model that generally will result in the earlier recognition of allowances for losses. · For available-for-sale debt securities with unrealized losses, entities will measure credit losses in a manner similar to what they do today, except that the losses will be recognized as allowances rather than reductions in the amortized cost of the securities. · Entities will have to disclose significantly more information, including information they use to track credit quality by year of origination for most financing receivables. For public business entities that are Securities and Exchange Commission (SEC) filers, the new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019 (for a calendar-year entity, it would be effective January 1, 2020). Early adoption will be permitted for all organizations for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company will be evaluating the impact of these amendments on its 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 presents the carrying amount, fair value, and placement in the fair value hierarchy of financial instruments at June 30, 2016 and December 31, 2015. 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.
