Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations [Text Block]	Note 1 - Summary of significant accounting policies Carolina Bank Holdings, Inc. (the “Holding Company”) is a North Carolina corporation organized in 2000. In August 2000 pursuant to the plan of share exchange approved by the shareholders of Carolina Bank (the “Bank”), all of the outstanding shares of common stock of the Bank were exchanged for shares of common stock of the Holding Company. The Holding Company presently has no employees. The Bank was incorporated in August 1996, and began banking operations in November 1996. It is engaged in lending and deposit gathering activities in Guilford, Alamance, Randolph and Forsyth counties of North Carolina and operates under the laws of North Carolina, the Rules and Regulations of the Federal Deposit Insurance Corporation and the North Carolina Commissioner of Banks. The Bank has three locations in Greensboro, two offices in Winston-Salem and an office in Asheboro, Burlington and High Point. The Bank opened its second office in Winston-Salem in August 2015 which had been under construction during 2014 and 2015. One of the Greensboro branches closed on July 31, 2015 due to an expiring lease in December of 2015. All banking offices are in the Piedmont Triad region of North Carolina. A wholesale mortgage division is located at the Greensboro corporate headquarters, and mortgage loan production offices are located in Burlington, Chapel Hill, and Sanford. The following is a description of the significant accounting and reporting policies that the Holding Company and Bank (collectively the “Company”) follow in preparing and presenting their consolidated financial statements. (a) Basis of presentation and consolidation The consolidated financial statements include the accounts of the Holding Company and its wholly-owned subsidiary, the Bank, which includes the wholesale mortgage division. The Bank also owns two limited liability companies for the purpose of holding foreclosed real estate, the assets and operations of which are consolidated into the Bank and included herein. All significant inter-company balances and transactions have been eliminated in consolidation. The Company’s financial statements are presented in accordance with Accounting Standards Codification (“ASC”) Topic 105, “ The FASB Accounting Standards Codification and The Hierarchy of Generally Accepted Accounting Principles (b) Use of estimates The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses and the valuation of other real estate owned. (c) Securities Investments in equity securities that have readily determinable fair values and all investments in debt securities are classified at acquisition into one of three categories and accounted for as follows: ⋅ securities held-to-maturity - reported at amortized cost; ⋅ trading securities - reported at fair value with unrealized gains and losses included in earnings, or; ⋅ securities available-for-sale - reported at estimated fair value with unrealized gains and losses reported as a separate component of comprehensive income (net of tax effect). The Company does not engage in any securities trading activities. Gains and losses on sales of securities are recognized on a specific identification basis. Purchases and sales of investments are recorded on a trade-date basis. Premiums and discounts are amortized into interest income using a method that approximates the level yield method. An investment in the Federal Home Loan Bank of $ 739,000 723,000 102,000 (d) Loans held for sale and hedging activities Loans held for sale represent residential real estate loans originated by the mortgage division, which was formed in 2007. Generally, optional commitments to sell these loans are made shortly after origination commitments are entered into with borrowers. 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. The Company also sells mortgage-backed securities on a forward basis to hedge some of its origination commitments to borrowers (“interest rate lock commitments”). Forward sale mortgage-backed securities and the value of interest rate lock commitments are also accounted for at fair value. Assumptions related to the closing ratio of mortgage loan commitments and the projected profit from loan sales are used to estimate the fair value of interest rate lock commitments. These estimates of fair value vary based on the level of interest rates and demand for residential mortgage loans. (e) Loans and allowance for loan losses Loans are carried at their principal amount outstanding. Interest income is recorded as earned on the accrual basis. Loan origination fees and certain origination costs are capitalized with the net fee or cost recognized as an adjustment to interest income using the interest method. The Company uses the allowance method in providing for loan losses. The provision for loan losses is based upon management’s estimate of the amount needed to maintain the allowance for loan losses at an adequate level to cover known and inherent risks of loss in the loan portfolio. In determining the provision amount, management gives consideration to current and anticipated economic conditions, the growth and composition of the loan portfolio, the relationship of the allowance for loan losses to outstanding loans, delinquencies, loss trends, and other factors. Management believes that the allowance for loan losses is appropriate in light of the risk inherent in the loan portfolio. While management uses the best information available to make evaluations, future adjustments may be necessary if economic and other conditions differ substantially from the assumptions used. The Company changed its allowance methodology during 2015 to more accurately reflect the estimated loss ratios inherent in the loan portfolio by increasing the look-back period for computing historical losses to the most recent five years from the most recent four years, adjusted for certain subjective factors. The change to five years in 2015 from four years produced a higher allowance and higher provision of approximately $ 571,000 825,000 1,733,000 2,579,000 Management considers loans to be impaired when based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Factors that influence management’s judgments include, but are not limited to, loan payment pattern, source of repayment, and value of collateral, if any. A loan would not be considered impaired if an insignificant delay in loan payment occurs and management expects to collect all amounts due. The major sources of identification of loans to be evaluated for impairment include past due and non-accrual reports, internally generated lists of certain risk grades, and regulatory reports of examination. Impaired loans are measured using either the discounted expected cash flow method or the value of collateral method. When the ultimate collectability of an impaired loan’s principal is in doubt, wholly or partially, all cash receipts are applied to principal. The accrual of interest on loans is discontinued when, in management’s opinion, the borrower may be unable to meet all payments as they become due. When the interest accrual is discontinued, all unpaid accrued interest is reversed and income is recognized only to the extent cash payments are received. (f) Other real estate owned 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 amount or the new fair value less costs to sell. Fair value is generally determined by appraisal. (g) Premises and equipment Premises and equipment, including leasehold improvements, are stated at cost less accumulated depreciation. Depreciation is provided over the estimated useful lives of the respective assets on the straight-line basis. Useful lives are estimated at twenty-five to forty-five years for buildings and three to ten years for equipment. Leasehold improvements are amortized over the expected terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. Expenditures for major renewals and betterments are capitalized and those for maintenance and repairs are charged to operating expenses as incurred. (h) Income taxes Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amount of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered in income. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that the tax benefits will not be realized. (i) Cash and cash equivalents For purposes of reporting cash flows, cash and cash equivalents includes cash and due from banks, federal funds sold, and interest-bearing deposits with banks. The Company maintains due from accounts with correspondent banks. During the normal course of business, the Company may have cash deposits with these banks that are in excess of federally insured limits. (j) Income per common share Basic income per common share is computed based on the weighted average number of common shares outstanding. Diluted income per share includes the dilutive effects of stock options. (k) Stock options The Company’s shareholders approved the 2009 Omnibus Stock Ownership and Long Term Incentive Plan (“Omnibus Plan”) in 2009 to replace three expired stock option plans, a nonqualified plan for directors and two incentive stock option plans for management and employees. The Omnibus Plan provides for the grant of incentive stock options, non-qualified stock options, restricted stock, long-term incentive compensation units and stock appreciation rights to employees and directors. An aggregate of 500,000 10,000 The Company accounts for stock option grants in accordance with the standard, Accounting for Stock-Based Compensation. The fair value of an option granted in 2014 to an executive was $ 22,000 The fair value of the option granted in 2014 was estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions: dividend yield of 0 30 0.90 2.15 Employee Stock Options Weighted Aggregate Average Intrinsic Exercise Value Shares Price ($000s) Balance at January 1, 2014 113,004 $ 10.25 $ - Issued 10,000 9.86 Exercised (5,904) 9.00 Forfeited (41,880) 9.41 Balance at December 31, 2014 75,220 10.77 - Issued - - Exercised (36,650) 10.38 Forfeited (2,000) 10.72 Balance at December 31, 2015 36,570 $ 11.16 $ 266 Exercisable at December 31, 2015 36,570 $ 11.16 $ 266 At December 31, 2015, stock options granted to employees were exercisable at a weighted average exercise price of $ 11.16 9.86 11.65 29 The aggregate intrinsic value of all stock options and of all exercisable options at December 31, 2015 was $ 266,000 (l) Reclassification Certain amounts in the 2014 consolidated financial statements have been reclassified to conform to the 2015 presentation. (m) Advertising Advertising costs are expensed as incurred. (n) Operating segments ASC 280, “ Segment Reporting (o) Retail repurchase agreements Funds are borrowed on an overnight basis through retail repurchase agreements with bank customers. Retail repurchase agreements are collateralized by securities of U.S. governmental agencies or by mortgage-backed securities issued by government sponsored entities. The market value of collateral pledged for retail repurchase agreements is monitored by the Company to equal or exceed the balances borrowed. (p) Impact of recently adopted accounting standards In January 2014, the FASB issued Accounting Standards Update (“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 1.3 In May 2014 and August 2015, 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 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 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, and ⋅ 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. In December 2012, the FASB issued its proposed Accounting Standards Update which set forth a current expected credit loss (“CECL”) model. This model will replace the multiple impairment models that currently exist for debt instruments in U.S. GAAP. The CECL model uses a single expected credit loss measurement objective for the allowance for credit loss. Under this model, the allowance for lifetime expected credit losses, when combined with the reported balance of the debt instrument, would reflect management’s estimate of the cash flows it expects to collect, based on its assessment of credit risk as of the reporting date. The FASB has completed its major decisions in this area, and expects to issue a final standard during the second quarter of 2016. As an SEC filer, the Company will be required to apply the guidance for 2019 interim and annual financial statements. Due to the magnitude of this change, these amendments are expected to have a material effect on the Company’s consolidated financial statements. The FASB is expected to complete and release revised standards for lease costs in 2016. The new standard will likely result in the capitalization of several of the Company’s leases, resulting in the addition of fixed assets and long-term liabilities onto the balance sheet. When finalized, this standard is not expected to have a material effect on net income. The closely-watched project, which has provoked much debate, is expected to become effective in 2019 for public companies. 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 December 31, 2015.

Loan grades are periodically re-evaluated during servicing, internal loan reviews, and external loan reviews. The general categories of the internal loan rating classification are: · Pass - Acceptable loans. · Special Mention - Loans with potential identified weaknesses in administration or servicing. · Classified - Adversely classified loans with identified weaknesses, and potential or identified losses of principal and/or interest due.

Non-accrual loans are not returned to accrual status unless principal and interest are current and borrowers have demonstrated the ability to make contractual payments. Accrued interest is reversed through a charge to income when loans are placed on non-accrual and future payments on non-accrual loans are generally applied to principal. The following is a summary of non-accrual loans at December 31, 2015 and 2014: December 31, December 31, 2015 2014 (in thousands) Real Estate Loans: Construction & development $ 175 $ 990 Commercial real estate 1,735 3,107 Home equity lines 265 355 Residential real estate 935 1,923 Total real estate 3,110 6,375 Commercial & industrial - 83 Consumer & other - - Total loans $ 3,110 $ 6,458 During 2015 and 2014, the Company restructured certain loans to improve the likelihood that the loans would be repaid in full under the modified terms in accordance with reasonable repayment schedules. Management evaluates each of these loans in accordance with GAAP 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 · Term Modification · Interest Only Modification · Payment Modification · Combination Modification Available commitments for troubled debt restructurings outstanding as of December 31, 2015 totaled $243,000. The following tables present troubled debt restructurings as of December 31, 2015 and 2014: Troubled Debt Restructurings December 31, 2015 Non-Accrual Total Accrual Status Status Modifications # Amount # Amount # Amount ($ in thousands) Real Estate Loans: Construction & development 0 $ - 1 $ 175 1 $ 175 Commercial real estate 12 7,073 1 338 13 7,411 Home equity lines 0 - 0 - 0 - Residential real estate 11 2,252 2 388 13 2,640 Total real estate 23 9,325 4 901 27 10,226 Commercial & industrial 1 362 0 - 1 362 Consumer & other 0 - 0 - 0 - Total loans 24 $ 9,687 4 $ 901 28 $ 10,588 December 31, 2014 Non-Accrual Total Accrual Status Status Modifications # Amount # Amount # Amount ($ in thousands) Real Estate Loans: Construction & development 1 $ 66 4 $ 990 5 $ 1,056 Commercial real estate 12 7,360 4 2,339 16 9,699 Home equity lines 0 - 0 - 0 - Residential real estate 10 1,943 5 920 15 2,863 Total real estate 23 9,369 13 4,249 36 13,618 Commercial & industrial 2 405 1 5 3 410 Consumer & other 0 - 0 - 0 - Total loans 25 $ 9,774 14 $ 4,254 39 $ 14,028 The Bank’s policy is that loans placed on non-accrual will typically remain on non-accrual status until all principal and interest payments are brought current and the prospect for future payment in accordance with the loan agreement appears relatively certain. 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 allowances 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. The Company made loans in the ordinary course of business to certain directors and executive officers of the Company and to their affiliates and associates. The total amount of such loans outstanding was $4,084,000 and $8,732,000 at December 31, 2015 and 2014, respectively. During 2015, new loans were $982,000 and repayments were $5,630,000, exclusive of retired directors. These loans were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with borrowers not related to the lender.

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Note 8 - Income taxes The Company does not have an accrual for uncertain tax positions as of December 31, 2015 and 2014, as deductions taken and benefits accrued are generally widely understood administrative practices and procedures. Any potential income tax adjustments would likely result in timing differences which would transfer a tax cost or benefit from one year to another year. The Company’s income taxes were examined for 2013, with no adjustments. With limited exceptions, income tax returns prior to 2012 are not subject to examination by the taxing authorities. Deferred tax assets represent the future tax benefit of deductible differences, and if it is more likely than not that a tax asset will not be realized, a valuation allowance is required to reduce the recorded deferred tax assets to net realizable value. At December 31, 2015 and 2014, management believes realization of the deferred tax assets is more likely than not and accordingly has not recorded a valuation allowance. 2015 2014 (in thousands) Current Federal $ 1,747 $ 957 State 425 208 2,172 1,165 Deferred Federal 238 (266) State 92 (15) 330 (281) $ 2,502 $ 884 34 2015 2014 (in thousands) Tax provision at statutory rate $ 2,811 $ 1,438 Increase (decrease) in income taxes resulting from State income taxes net of federal benefit 271 165 Decrease in deferred state income tax assets from a decrease in future state tax rates 92 - Increase in cash value of life insurance (123) (120) Nontaxable municipal income reduced by nondeductible interest expense (246) (236) Tax credits (370) (371) Other 67 8 $ 2,502 $ 884 2015 2014 (in thousands) Deferred tax assets Allowance for loan losses $ 2,151 $ 2,432 Deferred compensation expense 2,786 2,516 Impaired assets 437 478 Provision for warranty claims 567 537 Accrued Expenses 18 78 Carryforward credits 58 163 Unrealized losses, net of gains, on forward sale mortgage-backed securities 11 - Other 68 49 Gross deferred tax assets 6,096 6,253 Deferred tax liabilities Depreciable basis of premises and equipment 789 669 Deferred loan costs 316 333 Prepaid assets 19 93 Interest rate lock commitments 144 Unrealized gain on securities 366 587 Gross deferred tax liabilities 1,634 1,682 Net deferred tax assets $ 4,462 $ 4,571

Regulatory Capital Requirements under Banking Regulations [Text Block]	Note 10 - Regulatory matters Federal and state banking regulations place certain restrictions on dividends paid and loans or advances made by the Bank to the Company. The total amount of dividends, which may be paid at any date, is generally limited to the dividend capacity of the Bank, and loans or advances are limited to 15 percent of the Bank’s common stock and surplus on a secured basis. The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of the Company’s and the Bank’s assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Company’s and the Bank’s capital amounts and classifications are also subject to qualitative judgments by the regulators as to components, risk weighting, and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the table below) of Total, Tier 1, and Common Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital to average assets (as defined). At December 31, 2015, management believes that the Company and the Bank met all capital adequacy requirements. As of December 31, 2015, the Bank was categorized as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized the Bank must maintain minimum total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the following table.

Derivatives and Financial Instruments [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	Note 12 - Derivatives and financial instruments A derivative is a financial instrument 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 derivatives as either assets or liabilities in the balance sheet and to measure those instruments at fair value. Changes in the fair value of 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.

Compensation and Retirement Disclosure [Abstract]
Compensation and Employee Benefit Plans [Text Block]	Note 13 - Employee benefit plans All employees of the Company who meet certain eligibility requirements can elect to participate in the Bank’s 401(k) plan. Participants may make voluntary contributions resulting in salary deferrals in accordance with Section 401(k) of the Internal Revenue Code and the plan documents. The Company makes a 100% matching contribution up to a maximum of six percent of compensation, which is vested immediately. The Company’s matching expense was $633,000 in 2015 and $559,000 in 2014. The Company has a nonqualified deferred compensation plan under which directors may elect to defer their directors’ fees. Participating directors receive an additional matching contribution for monthly fees and the amounts deferred are invested solely in Company stock that is held in a rabbi trust. The matching contribution was 25% during 2015 and 2014. The Company stock held by the trust and the related deferred compensation liability are recorded at an amount equal to the original compensation deferred. Changes in the fair value of the stock are not recognized in the Company’s financial statements. At December 31, 2015, deferred directors’ fees of $1,831,000 had been used to purchase 258,665 shares of the Company’s stock held by the trust after distribution of shares to retiring directors. Deferred directors’ fees of $24,000 were also remitted to the trust before December 31, 2015 to purchase stock or make director distributions in 2016. In addition, the Company has a supplemental executive retirement plan for certain officers. The plan was expanded in 2008 to include certain new officers and directors. The future benefits of the plan are funded primarily by life insurance policies on certain employees with the Company designated as the beneficiary. Expenses were $734,000 in 2015 and $873,000 in 2014 related to this plan. At December 31, 2015 and 2014, other liabilities include $5,772,000 and $5,281,000, respectively, for this supplemental retirement plan.

Fair Value Measurements [Abstract]
Fair Value, Measurement Inputs, Disclosure [Text Block]	Note 14 - Fair value of financial statements 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 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, or are traded by brokers and dealers in active over-the-counter markets. U.S. Treasury securities, actively traded corporate bonds and stocks, and money market and mutual funds are Level 1 securities. Level 2 securities include mortgage-backed securities issued by government sponsored entities, municipal bonds, certain corporate debt securities, and asset-backed securities issued by government agencies. 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 (“IRLCs”) 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 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 interest rate lock commitments as Level 3. Gain 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 2015 after having suspended recognition in 2014 due to immateriality.

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 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 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 December 31, 2015 and 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 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 other real estate owned as nonrecurring Level 3 within the valuation hierarchy.

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: 14,954,000 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 12 years in 2015 and 12.5 years in 2014. 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.

Summary of significant accoun26

Summary of significant accounting policies (Policies)	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	(a) Basis of presentation and consolidation The consolidated financial statements include the accounts of the Holding Company and its wholly-owned subsidiary, the Bank, which includes the wholesale mortgage division. The Bank also owns two limited liability companies for the purpose of holding foreclosed real estate, the assets and operations of which are consolidated into the Bank and included herein. All significant inter-company balances and transactions have been eliminated in consolidation. The Company’s financial statements are presented in accordance with Accounting Standards Codification (“ASC”) Topic 105, “ The FASB Accounting Standards Codification and The Hierarchy of Generally Accepted Accounting Principles
Use of Estimates, Policy [Policy Text Block]	(b) Use of estimates The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses and the valuation of other real estate owned.
Marketable Securities, Policy [Policy Text Block]	(c) Securities Investments in equity securities that have readily determinable fair values and all investments in debt securities are classified at acquisition into one of three categories and accounted for as follows: ⋅ securities held-to-maturity - reported at amortized cost; ⋅ trading securities - reported at fair value with unrealized gains and losses included in earnings, or; ⋅ securities available-for-sale - reported at estimated fair value with unrealized gains and losses reported as a separate component of comprehensive income (net of tax effect). The Company does not engage in any securities trading activities. Gains and losses on sales of securities are recognized on a specific identification basis. Purchases and sales of investments are recorded on a trade-date basis. Premiums and discounts are amortized into interest income using a method that approximates the level yield method. An investment in the Federal Home Loan Bank of $ 739,000 723,000 102,000
Loans Held For Sale And Hedging Activities [Policy Text Block]	(d) Loans held for sale and hedging activities Loans held for sale represent residential real estate loans originated by the mortgage division, which was formed in 2007. Generally, optional commitments to sell these loans are made shortly after origination commitments are entered into with borrowers. 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. The Company also sells mortgage-backed securities on a forward basis to hedge some of its origination commitments to borrowers (“interest rate lock commitments”). Forward sale mortgage-backed securities and the value of interest rate lock commitments are also accounted for at fair value. Assumptions related to the closing ratio of mortgage loan commitments and the projected profit from loan sales are used to estimate the fair value of interest rate lock commitments. These estimates of fair value vary based on the level of interest rates and demand for residential mortgage loans.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	(e) Loans and allowance for loan losses Loans are carried at their principal amount outstanding. Interest income is recorded as earned on the accrual basis. Loan origination fees and certain origination costs are capitalized with the net fee or cost recognized as an adjustment to interest income using the interest method. The Company uses the allowance method in providing for loan losses. The provision for loan losses is based upon management’s estimate of the amount needed to maintain the allowance for loan losses at an adequate level to cover known and inherent risks of loss in the loan portfolio. In determining the provision amount, management gives consideration to current and anticipated economic conditions, the growth and composition of the loan portfolio, the relationship of the allowance for loan losses to outstanding loans, delinquencies, loss trends, and other factors. Management believes that the allowance for loan losses is appropriate in light of the risk inherent in the loan portfolio. While management uses the best information available to make evaluations, future adjustments may be necessary if economic and other conditions differ substantially from the assumptions used. The Company changed its allowance methodology during 2015 to more accurately reflect the estimated loss ratios inherent in the loan portfolio by increasing the look-back period for computing historical losses to the most recent five years from the most recent four years, adjusted for certain subjective factors. The change to five years in 2015 from four years produced a higher allowance and higher provision of approximately $ 571,000 825,000 1,733,000 2,579,000 Management considers loans to be impaired when based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Factors that influence management’s judgments include, but are not limited to, loan payment pattern, source of repayment, and value of collateral, if any. A loan would not be considered impaired if an insignificant delay in loan payment occurs and management expects to collect all amounts due. The major sources of identification of loans to be evaluated for impairment include past due and non-accrual reports, internally generated lists of certain risk grades, and regulatory reports of examination. Impaired loans are measured using either the discounted expected cash flow method or the value of collateral method. When the ultimate collectability of an impaired loan’s principal is in doubt, wholly or partially, all cash receipts are applied to principal. The accrual of interest on loans is discontinued when, in management’s opinion, the borrower may be unable to meet all payments as they become due. When the interest accrual is discontinued, all unpaid accrued interest is reversed and income is recognized only to the extent cash payments are received.
Loans and Leases Receivable, Real Estate Acquired Through Foreclosure, Policy [Policy Text Block]	(f) Other real estate owned 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 amount or the new fair value less costs to sell. Fair value is generally determined by appraisal.
Property, Plant and Equipment, Policy [Policy Text Block]	(g) Premises and equipment Premises and equipment, including leasehold improvements, are stated at cost less accumulated depreciation. Depreciation is provided over the estimated useful lives of the respective assets on the straight-line basis. Useful lives are estimated at twenty-five to forty-five years for buildings and three to ten years for equipment. Leasehold improvements are amortized over the expected terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. Expenditures for major renewals and betterments are capitalized and those for maintenance and repairs are charged to operating expenses as incurred.
Income Tax, Policy [Policy Text Block]	(h) Income taxes Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amount of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered in income. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that the tax benefits will not be realized.
Cash and Cash Equivalents, Policy [Policy Text Block]	(i) Cash and cash equivalents For purposes of reporting cash flows, cash and cash equivalents includes cash and due from banks, federal funds sold, and interest-bearing deposits with banks. The Company maintains due from accounts with correspondent banks. During the normal course of business, the Company may have cash deposits with these banks that are in excess of federally insured limits.
Earnings Per Share, Policy [Policy Text Block]	(j) Income per common share Basic income per common share is computed based on the weighted average number of common shares outstanding. Diluted income per share includes the dilutive effects of stock options.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	(k) Stock options The Company’s shareholders approved the 2009 Omnibus Stock Ownership and Long Term Incentive Plan (“Omnibus Plan”) in 2009 to replace three expired stock option plans, a nonqualified plan for directors and two incentive stock option plans for management and employees. The Omnibus Plan provides for the grant of incentive stock options, non-qualified stock options, restricted stock, long-term incentive compensation units and stock appreciation rights to employees and directors. An aggregate of 500,000 10,000 The Company accounts for stock option grants in accordance with the standard, Accounting for Stock-Based Compensation. The fair value of an option granted in 2014 to an executive was $ 22,000 The fair value of the option granted in 2014 was estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions: dividend yield of 0 30 0.90 2.15 Employee Stock Options Weighted Aggregate Average Intrinsic Exercise Value Shares Price ($000s) Balance at January 1, 2014 113,004 $ 10.25 $ - Issued 10,000 9.86 Exercised (5,904) 9.00 Forfeited (41,880) 9.41 Balance at December 31, 2014 75,220 10.77 - Issued - - Exercised (36,650) 10.38 Forfeited (2,000) 10.72 Balance at December 31, 2015 36,570 $ 11.16 $ 266 Exercisable at December 31, 2015 36,570 $ 11.16 $ 266 At December 31, 2015, stock options granted to employees were exercisable at a weighted average exercise price of $ 11.16 9.86 11.65 29 The aggregate intrinsic value of all stock options and of all exercisable options at December 31, 2015 was $ 266,000

Repurchase Agreements, Collateral, Policy [Policy Text Block]	(o) Retail repurchase agreements Funds are borrowed on an overnight basis through retail repurchase agreements with bank customers. Retail repurchase agreements are collateralized by securities of U.S. governmental agencies or by mortgage-backed securities issued by government sponsored entities. The market value of collateral pledged for retail repurchase agreements is monitored by the Company to equal or exceed the balances borrowed.
New Accounting Pronouncements, Policy [Policy Text Block]	(p) Impact of recently adopted accounting standards In January 2014, the FASB issued Accounting Standards Update (“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 1.3 In May 2014 and August 2015, 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 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 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, and ⋅ 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. In December 2012, the FASB issued its proposed Accounting Standards Update which set forth a current expected credit loss (“CECL”) model. This model will replace the multiple impairment models that currently exist for debt instruments in U.S. GAAP. The CECL model uses a single expected credit loss measurement objective for the allowance for credit loss. Under this model, the allowance for lifetime expected credit losses, when combined with the reported balance of the debt instrument, would reflect management’s estimate of the cash flows it expects to collect, based on its assessment of credit risk as of the reporting date. The FASB has completed its major decisions in this area, and expects to issue a final standard during the second quarter of 2016. As an SEC filer, the Company will be required to apply the guidance for 2019 interim and annual financial statements. Due to the magnitude of this change, these amendments are expected to have a material effect on the Company’s consolidated financial statements. The FASB is expected to complete and release revised standards for lease costs in 2016. The new standard will likely result in the capitalization of several of the Company’s leases, resulting in the addition of fixed assets and long-term liabilities onto the balance sheet. When finalized, this standard is not expected to have a material effect on net income. The closely-watched project, which has provoked much debate, is expected to become effective in 2019 for public companies. 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 December 31, 2015.

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 December 31, 2015 and 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.
