Summary of significant accounting policies	12 Months Ended
	Dec. 31, 2014
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 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 four locations in Greensboro and an office in Asheboro, Burlington, High Point and Winston-Salem. In addition, the Bank has a second office under construction in Winston-Salem with an estimated opening date in the second quarter 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, Pinehurst, 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. Carolina Bank also owns two limited liability companies for the purpose of holding foreclosed real estate, the assets and operations of which are consolidated into Carolina 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”, which codifies generally accepted accounting principles (GAAP) in the United States.
		(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 $723,000 and $964,000 at December 31, 2014 and 2013, respectively, is included in other assets and represents restricted stock which is carried at cost and is required for advances or borrowings. An investment in Pacific Coast Bankers’ Bancshares of $102,000 at December 31, 2014 and 2013 is included in other assets and carried at cost.
		(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, in years prior to 2013, also sold mortgage-backed securities on a forward basis to hedge some of its origination commitments to borrowers. Forward sale mortgage- backed securities and the value of the estimated loan commitments that were hedged are also accounted for at fair value. Assumptions related to the closing ratio of loan commitments and the projected profit from loan sales were used to estimate the fair value of hedged loan 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 2014 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 four years from the most recent three years, adjusted for certain subjective factors. The change to four years produced a higher allowance and higher provision of approximately $825,000 than using three years. Net loan charge-offs, which are loan charge-offs less recoveries, are the basis for computing loan loss trends, and the Company generally records charge-offs on non-performing real estate loans when new appraisals are obtained rather than waiting until collection efforts have been exhausted. Net loan charge-offs for 2014 and 2013 were $2,579,000 and $5,731,000, respectively.
	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 (Director Plan) and two incentive stock option plans for management and employees (Employee Plans). 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 shares of the Company’s common stock have been reserved for issuance under the terms of the Omnibus Plan; of which, 10,000 incentive stock options have been issued.
	The Company accounts for stock option grants in accordance with the standard, Accounting for Stock-Based Compensation. The fair value of options granted in 2014 to an executive was $22,000 which was expensed in 2014. As of December 31, 2014, there was no unrecognized compensation cost related to non-vested share-based compensation.
	The fair value of each option grant was estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions for 2014: dividend yield of 0%, expected volatility of 30%, risk-free interest rate of 0.90%, and weighted average expected lives of three years. The weighted average fair value per share of options granted for the year ended December 31, 2014 was $2.15.
	Following is a summary of stock options outstanding under both plans, adjusted for the stock splits that have occurred in prior years:
			Employee Stock Options
					Weighted		Aggregate
					Average		Intrinsic

	At December 31, 2014, stock options granted to employees were exercisable at a weighted average exercise price of $10.77. The range of exercise prices at December 31, 2014 for stock option plans was $9.86 - $11.65. The weighted average remaining contractual term for outstanding stock options was 34 months.
	The aggregate intrinsic value of all stock options and of all exercisable options at December 31, 2014 was $0.
		(l)	Reclassification
	Certain amounts in the 2013 consolidated financial statements have been reclassified to conform to the 2014 presentation.
		(m)	Advertising
	Advertising costs are expensed as incurred.
		(n)	Operating segments
	ASC 280, “Segment Reporting”, provides guidance on the reporting and disclosure of information about operating segments. The Company is considered to have three principal business segments in 2014 and 2013, the Commercial/Retail bank, the Mortgage division, and the holding company. The Mortgage division began originating home mortgage loans through third parties and selling these loans to investors in late 2007. The Mortgage Division added a retail mortgage loan production office in July 2010 and another four retail mortgage loan production offices between 2012 and 2014. Retail mortgage loan officers are also located in five of eight full service bank offices. Financial performance for 2014 and 2013 and selected balance sheet information at December 31, 2014 and 2013 for each segment is shown in Note 16.
		(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
	On January 17, 2014, the FASB issued ASU 2014-04, Receivables—Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure (a consensus of the FASB Emerging Issues Task Force), to clarify when an in substance repossession or foreclosure occurs, and address the diversity in practice regarding when a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be reclassified as real estate property (i.e., taken possession of the real estate). Specifically, an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) obtaining legal title upon completion of a foreclosure or (2) obtaining interest in the property in satisfaction of the loan through a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the ASU requires interim and annual disclosure of both (1) the amount of foreclosed real estate held and (2) the recorded investment in mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The amendments will be effective for the Company on a prospective basis for interim and annual reporting periods beginning January 1, 2015. Early adoption and a modified retrospective application are permitted. These amendments are not expected to have a material effect on the Company’s statement of financial position.
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), to provide guidance on accounting for investments by a reporting entity in flow-through limited liability entities that manage or invest in affordable housing projects that qualify for the low income housing tax credit. The ASU modifies the conditions that an entity must meet to be eligible to use a method other than the equity or cost methods to account for qualified affordable housing project investments. The ASU permits reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if those conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). Further, the decision to apply the proportional amortization method of accounting is an accounting policy decision that should be applied consistently to all qualifying affordable housing project investments rather than a decision to be applied to individual investments. An entity that has used the effective yield method to account for its investments in qualified affordable housing before the date of adoption may continue to apply the effective yield method for those preexisting investments. The amendments will be effective for the Company on a retrospective basis for interim and annual reporting periods beginning January 1, 2015. Early adoption is permitted. The Company has a $3 million qualified affordable housing investment of which $1,062,000 has been amortized through non-interest income over the past few years. The amount of amortization, which reduced non-interest income, was $315,000 and $217,000 for the years ending December 31, 2014 and 2013, respectively. Income tax credits which reduced income tax expense were $370,000 and $366,000 for the years ending December 31, 2014 and 2013, respectively. Under the proportional amortization method, part of the amortization which has reduced non-interest income would be reclassified to increase income tax expense. The Company does not expect these amendments to have a material effect on its financial statements.
In August, 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. The ASU is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. In connection with preparing financial statements, management will need to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the organization’s ability to continue as a going concern within one year after the date that the financial statements are issued. The first management assessments are required in the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. These assessments and disclosures are not expected to have a material effect on the Company’s consolidated financial statements.
In January, 2015, the FASB issued ASU No. 2015-01, Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items. The ASU eliminates the concept of extraordinary items from U.S. GAAP. Existing U.S. GAAP required that an entity separately classify, present, and disclose extraordinary events and transactions. Presently, an event or transaction is presumed to be an ordinary and usual activity of the reporting entity unless the event or transaction is both unusual in nature and infrequent in occurrence. The amendments will eliminate the requirements for reporting entities to consider whether an underlying event or transaction is extraordinary, however, the presentation and disclosure guidance for items that are unusual in nature or occur infrequently will be retained and will be expanded to include items that are both unusual in nature and infrequently occurring. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. The amendments may be applied either prospectively or retrospectively to all prior periods presented in the financial statements. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. These amendments are not expected to have a material effect on the Company’s statement of financial position.
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 will be effective for the Company for reporting period beginning with the first quarter of 2015. The Company will apply the guidance by making a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. The Company does not expect these amendments to have a material effect on its 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, 2016. The Company does not expect these amendments to have a material effect on its financial statements.
In January 2014, the FASB amended 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 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 period beginning after December 15, 2014, with early implementation of the guidance permitted. In implementing this guidance, assets that are reclassified from real estate to loans are measured at the carrying value of the real estate at the date of adoption. Assets reclassified from loans to real estate are measured at the lower of the net amount of the loan receivable or the fair value of the real estate less costs to sell at the date of adoption. The Company does not expect these amendments to have a material effect on its 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 December 31, 2014. The FASB proposal on Current Expected Credit Loss (“CECL”) is expected to be released in 2015 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 current historical loss rate method currently used to calculate the allowance for loan losses.

	Municipal securities, mortgage-backed securities, corporate securities, and asset-backed securities were sold during 2014 and 2013 for gains totaling $274,000 and $272,000, respectively.
	At December 31, 2014, securities with a carrying value of approximately $25,327,000 were pledged to secure retail repurchase agreements and certain deposits.
	Management evaluates securities for other-than-temporary impairment at least quarterly. Consideration is given to the length of time and the extent to which the fair values have been less than amortized cost, the financial condition and near-term prospects of the security issuers, and the intent and ability to retain impaired investments for a period to allow recovery in fair value.
	At December 31, 2014, one corporate debt security with $972,000 in fair value and six municipal securities with $6,446,000 in fair value had total unrealized losses of $57,000. Values on these securities with unrealized losses fluctuate based on changes in the values of U.S. Treasury bonds with similar characteristics, debt ratings changes of the issuing institutions, financial performance of the related institutions, world events, and demand for the securities. As management has the ability and intent to hold these debt securities until maturity, no declines are deemed to be other-than-temporary.
	Information pertaining to securities with gross unrealized losses at December 31, 2014 and 2013, by category and length of time that individual securities have been in a continuous loss position, follows:

Receivables [Abstract]
Loans, Notes, Trade and Other Receivables Disclosure [Text Block]	Note 3 - Loans and allowance for loan losses
	The following is a description of loan categories and related risks factors:
	Construction & development - The construction and development loan portfolio includes loans to construct new homes, multifamily units, retail establishments, and commercial properties as well as development loans that facilitate the final construction of the aforementioned properties. A majority of properties being constructed are for low income housing and are being pre-sold to developers. A few of the properties being constructed are for speculative purposes with repayment dependent on the sale of completed construction to the final users of the property. This portfolio experienced the highest losses during the most recent economic downturn and generally has the highest risk of our loan portfolio; however, loans for speculative purposes have been reduced to limit risk.
	Commercial real estate - Commercial real estate loans include owner-occupied commercial real estate loans to operating businesses, which are loans for long-term financing of land and buildings, and are repaid by cash flow generated by business operations. This loan portfolio also includes extensions of credit to real estate developers or investors where repayment is dependent on the sale of real estate or income generated from the real estate collateral. Apartment buildings, office and industrial buildings, motels, nursing homes, and retail shopping centers are examples of properties financed by commercial real estate loans. Loans in this portfolio segment are sensitive to declines in real estate values and to the cash flow of commercial borrowers.
	Home equity lines – Home equity lines of credit are revolving, open-end loans secured by 1-4 family residential properties, generally junior liens at a loan to value of less than 90%. These loans are generally for a term of 15 years, require interest payments monthly, and have floating interest rates tied to the prime rate although fixed rates are also offered. Home equity lines can be sensitive to key economic measures that impact consumers such as unemployment, home prices, and the prime interest rate.
	Residential real estate – Residential real estate loans are closed-end loans secured by 1-4 family residential properties, primarily first liens with a small percentage of junior liens. These loans are generally for a term of 5 to 30 years, require interest and principal payments monthly, and are primarily fixed rate. This portfolio can be sensitive to key economic measures that impact consumers such as unemployment and home values.
	Commercial & industrial - The commercial loan portfolio segment includes commercial and industrial loans to commercial customers for use in normal business operations to finance working capital needs, equipment purchases or other expansion projects. Collection risk in this portfolio is driven by the creditworthiness of underlying borrowers, particularly cash flow from customers’ business operations.
	Consumer & other - The consumer& other loan portfolio segment includes direct consumer installment loans and overdrafts. These loans may be secured by vehicles, stocks, deposits or may be unsecured. Fixed and variable rates are offered. Loans in this portfolio segment are sensitive to unemployment and other key consumer economic measures.

Loans are determined to be impaired when, based on current information and events, it is probable that all amounts will not be collected when due according to the contractual terms of the original loan agreement. At December 31, 2014 and 2013, the total recorded investment in impaired loans amounted to approximately $18,560,000 and $29,268,000, respectively. Of these impaired loans, $6,458,000 and $16,731,000 were on non-accrual at December 31, 2014 and 2013, respectively.
The recorded investment and related information for impaired loans is summarized as follows:

Loans are graded according to an internal loan rating classification system when originated. 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.
The following is a breakdown of loans by the general categories of the internal rating system:

Loans that are past due 90 days or more or where there is serious doubt as to collectability are placed on non-accrual status. 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, 2014 and 2013:

During 2014 and 2013, 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 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.
Available commitments for troubled debt restructurings outstanding as of December 31, 2014 totaled $395,000.

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 $8,732,000 and $8,290,000 at December 31, 2014 and 2013, respectively. During 2014, new loans were $4,422,000 and repayments were $2,415,000, 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.

Subordinated Borrowings [Abstract]
Subordinated Borrowings Disclosure [Text Block]	Note 7 - Subordinated debentures
	In December 2004, the Company issued $10,310,000 of unsecured junior subordinated debentures which accrue and pay interest quarterly at three month LIBOR plus 2% per annum. These debentures were issued to Carolina Capital Trust (“Carolina Trust”), a wholly owned subsidiary of the Company which is not consolidated in these consolidated financial statements pursuant to accounting standards incorporated within ASC 810, “Consolidation”. Carolina Trust acquired these debentures using the proceeds of its offerings of common securities to the Company and $10 million of Trust Preferred Securities to outside investors. The Trust Preferred Securities qualify as Tier 1 capital under current Federal Reserve Board guidelines. The Dodd-Frank Wall Street Reform and Consumer Protection Act eliminates trust preferred securities as an element of Tier 1 capital for certain institutions. However, bank holding companies with assets of less than $15 billion as of December 31, 2009, will be permitted to include trust preferred securities that were issued before May 19, 2010, as Tier 1 capital. The Company has entered into contractual arrangements which, in the aggregate, constitute a full, irrevocable and unconditional guarantee on a subordinated basis by the Company of the obligations of Carolina Trust under the Trust Preferred Securities. The Trust Preferred Securities are redeemable upon maturity of the debentures on January 7, 2035, or upon earlier redemption as provided in the indenture. The Company has the right to redeem the debentures purchased by Carolina Trust in whole or in part, on or after January 7, 2010.
	In August and September of 2008, Carolina Bank issued $9,300,000 of unsecured junior subordinated notes to outside investors which accrue and pay interest quarterly at three month LIBOR plus 4% per annum. The notes qualify as Tier 2 capital for the Bank, subject to a 20% reduction which began on October 1, 2013 and continues each year thereafter until maturity. The notes are redeemable upon maturity on September 30, 2018, or earlier at the Bank’s option, in whole or part subject to regulatory approval, beginning September 30, 2013. The expenses of the offering of $373,000 were capitalized at issuance and were amortized over sixty months. The notes are subordinate to the rights of payment to depositors, bankers acceptances, letters of creditors and general creditors.

Income_taxes

Income taxes	12 Months Ended

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, 2014 and 2013, 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 2008 and 2009, and adjustments were primarily timing differences. With limited exceptions, income tax returns prior to 2011 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, 2014 and 2013, management believes realization of the deferred tax assets is more likely than not and accordingly has not recorded a valuation allowance.
	The provision for income tax expense (benefit) consisted of the following for the years ended December 31:

Equity [Abstract]
Preferred Stock [Text Block]	Note 9 – Preferred stock
	In December 2008, the shareholders of the Company approved an amendment to the Articles of Incorporation authorizing the issuance of up to 1,000,000 shares of preferred stock, no par value. In January 2009, the Company issued 16,000 shares of preferred stock to the U.S. Treasury and received $16 million under the Capital Purchase Program. The Company granted a warrant to purchase 357,675 shares of common stock at a price of $6.71 per share to the U.S. Treasury as part of the preferred stock transaction. In accordance with applicable accounting principles, the preferred stock and common stock warrant were valued independently and their relative fair market values were allocated to the $16 million received. Under the relative value method, $14,159,000 was allocated to the preferred stock and $1,841,000 to the common stock warrant. The discount of $1,841,000 on the preferred stock was accreted over five years using the effective yield method, thereby increasing preferred stock dividends. The accretion of the discount was $0 and $371,000 in 2014 and 2013, respectively. Dividends at 5% per annum were paid for the first five years. The dividend rate increased to 9% per annum in February 2014.
	The U.S. Treasury sold its holding of $16 million in preferred stock to private investors in February 2013, and the warrant to the U.S. Treasury was repurchased by the Company for $1.8 million in April 2013. The Company retired 5,006 shares of its outstanding preferred stock for $4,958,000 in August 2013 and currently has 10,994 shares outstanding at $10,994,000.

Regulatory matters	12 Months Ended
	Dec. 31, 2014
Banking and Thrift [Abstract]
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. In addition, dividends paid by the Bank to the Company would be prohibited if the effect would cause the Bank’s capital to be reduced below applicable minimum regulatory capital requirements.
	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 and 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, 2014, management believes that the Company and the Bank met all capital adequacy requirements.
	As of December 31, 2014, the most recent notification from the FDIC categorized the Bank 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.
	The Company’s and the Bank’s actual capital amounts and ratios as of December 31, 2014 and 2013 are presented in the table that follows:

	Loans
	In the normal course of business there are outstanding commitments for the extension of credit which are not reflected in the financial statements. At December 31, 2014 and 2013, pre-approved but unused lines of credit for loans totaled approximately $174,665,000 and $159,756,000. In addition, the Company had $1,812,000 and $1,701,000 in performance standby letters of credit at December 31, 2014 and 2013, respectively. These commitments represent no more than the normal lending risk that the Bank commits to its borrowers. If these commitments are drawn, the Company will obtain collateral if it is deemed necessary based on management’s credit evaluation of the counterparty. Management believes that these commitments can be funded through normal operations.

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.

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, primarily on a best efforts basis, whereby optional commitments to sell mortgage loans are consummated at approximately the same time that optional commitments are given to borrowers to originate the loans. Generally within three weeks after loan funding, the loans are sold to investors in accordance with previously agreed upon terms.

The below presents the aggregate fair value and aggregate unpaid principal of loans held for sale at December 31, 2014 and 2013:

Interest income on loans held for sale is recognized based on contractual rates and is reflected in interest income on loans in the consolidated statements of income. The following table details net gains resulting from changes in fair value of these loans which were recorded in mortgage banking income in the consolidated statements of income during the years ended December 31, 2014 and 2013, respectively. These changes in fair value are mostly offset by economic hedging activities and also fluctuate based on the change in the aggregate loan principal outstanding. An immaterial portion of these amounts was attributable to changes in instrument-specific credit risk.

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 $559,000 in 2014 and $645,000 in 2013.
	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 2014 and 2013. 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, 2014, deferred directors’ fees of $1,465,000 had been used to purchase 231,741 shares of the Company’s stock held by the trust after distribution of shares to retiring directors. Deferred directors’ fees of $23,000 were also remitted to the trust before December 31, 2014 to purchase stock in 2015.
	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 $873,000 in 2014 and $993,000 in 2013 related to this plan. At December 31, 2014 and 2013, other liabilities include $5,281,000 and $4,508,000, 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”, which provides a framework for measuring fair value under GAAP and enhances disclosures about fair value measurements. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company utilizes fair value measurements to record fair value adjustments to certain assets and to determine fair value disclosures. The Company has not elected the fair value option to value liabilities. Securities available-for-sale and loans held for sale are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets on a nonrecurring basis, such as impaired loans held for investment and certain other assets. These nonrecurring fair value adjustments typically involve application of lower of cost or market accounting or write-downs of individual assets.
	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, 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.
	Loans Held for Sale
	The Company opted to account for loans held for sale at fair value which is based on what secondary markets are currently offering for portfolios with similar characteristics. As such, the Company classifies loans subjected to recurring fair value adjustments as Level 2 valuation.
	Interest Rate Lock Commitments
	The Mortgage Division of the Company hedges some of its residential mortgage loans held for sale by selling mortgage-backed securities on a forward basis. The forward sale mortgage-backed securities are later purchased or closed when mandatory loan sales are consummated for the related mortgages that are originated. The value of the estimated loan commitments and open hedges are marked to market through the income statement. The significant unobservable input used in the Level 3 fair value measurement of the Company’s Interest Rate Lock Commitments “IRLCs” on hedged 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. Generally, the fair value of an IRLC is positive (negative) if the prevailing interest rate is lower (higher) than the IRLC rate. Therefore, an increase in the closing ratio (i.e., higher percentage of loans are estimated to close) will result in the fair value of the IRLC increasing if in a gain position, or decreasing if in a loss position. The closing ratio is largely dependent on the loan processing stage that a loan is currently in 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 between the commitment date and period end, typically month end. The Company classifies interest rate lock commitments as Level 3. Gain on interest rate lock commitments for the period is included in mortgage banking income of non-interest income on the Consolidated Statements of Income. There have been no changes in valuation techniques for years ended December 31, 2014 and 2013; however, the Mortgage Division discontinued hedging during early 2013 due to economic factors. All loans are currently sold on a “best efforts” basis where optional commitments are made with investors to sell loans shortly after optional commitments are consummated to originate loans with borrowers. Below is a summary of activity related to interest rate lock commitments for the years ended December 31, 2014 and 2013.

	Fair Value on a Non-recurring Basis. 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, 2014 and 2013, 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.
	Assets measured at fair value on a non-recurring basis at December 31, 2014 and 2013 are summarized below:
		Assets

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 December 31, 2014, there were no fair value adjustments related to $15,644,000 of securities held-to-maturity.
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.
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 12.5 years in 2014 and 13.5 years in 2013. 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.
The following presents the carrying amount, fair value, and placement in the fair value hierarchy of financial instruments at December 31, 2014 and 2013. 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.

	The Mortgage Division experienced strong growth in originations from 2007 through 2012 due to low interest rates and due to the acquisition of a retail loan production office in July of 2010. Originations decreased after the increase in mortgage rates in the second quarter of 2013 which curtailed much of the refinancing by borrowers that had dominated earlier periods. Loan originations dropped approximately 36% in 2014 from 2013. Interest rate risk has been minimized by obtaining optional loan sales commitments when loan origination commitments are made or by entering into hedging transactions whereby mortgage-backed securities are sold for the estimated closing value of loan commitments. Borrower fraud is a risk that has been managed by prudent underwriting and by obtaining indemnification from the originating bank or broker for the risks the Company assumes. Warranty provisions and related warranty liabilities have been recorded since 2009 to provide for potential claims that might arise from borrower fraud or underwriting errors. Warranty expenses, which are netted against mortgage banking income in the Consolidated Statements of Income, were $151,000 and $100,000 for 2014 and 2013, respectively. The warranty liability, which is available to fund future warranty claims, was $1,440,000 and $1,401,000 at December 31, 2014 and 2013, respectively. Fourteen warranty claims or losses and five fair value adjustments from repurchases totaling $1,054,000 have been incurred since establishment of the mortgage division in 2007. In addition, seven loans with a total current carrying balance, including fair value loss adjustments recorded when transferred, of $1,613,000 have been repurchased and are included in loans held for investment

Subsequent Events [Text Block]	Note 18 – Subsequent events
	Subsequent events are events or transactions that occur after the balance sheet date but before financial statements are issued. Recognized subsequent events are events or transactions that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing financial statements. Non-recognized subsequent events are events that provide evidence about conditions that did not exist at the date of the balance sheet but arose after that date. Management has reviewed events occurring through the date the consolidated financial statements were issued and no subsequent events occurred requiring accrual or disclosure.

Summary_of_significant_account1

Summary of significant accounting policies (Policies)	12 Months Ended
	Dec. 31, 2014
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. Carolina Bank also owns two limited liability companies for the purpose of holding foreclosed real estate, the assets and operations of which are consolidated into Carolina 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”, which codifies generally accepted accounting principles (GAAP) in the United States.
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 $723,000 and $964,000 at December 31, 2014 and 2013, respectively, is included in other assets and represents restricted stock which is carried at cost and is required for advances or borrowings. An investment in Pacific Coast Bankers’ Bancshares of $102,000 at December 31, 2014 and 2013 is included in other assets and carried at cost.
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, in years prior to 2013, also sold mortgage-backed securities on a forward basis to hedge some of its origination commitments to borrowers. Forward sale mortgage- backed securities and the value of the estimated loan commitments that were hedged are also accounted for at fair value. Assumptions related to the closing ratio of loan commitments and the projected profit from loan sales were used to estimate the fair value of hedged loan 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 2014 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 four years from the most recent three years, adjusted for certain subjective factors. The change to four years produced a higher allowance and higher provision of approximately $825,000 than using three years. Net loan charge-offs, which are loan charge-offs less recoveries, are the basis for computing loan loss trends, and the Company generally records charge-offs on non-performing real estate loans when new appraisals are obtained rather than waiting until collection efforts have been exhausted. Net loan charge-offs for 2014 and 2013 were $2,579,000 and $5,731,000, respectively.
	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 (Director Plan) and two incentive stock option plans for management and employees (Employee Plans). 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 shares of the Company’s common stock have been reserved for issuance under the terms of the Omnibus Plan; of which, 10,000 incentive stock options have been issued.
	The Company accounts for stock option grants in accordance with the standard, Accounting for Stock-Based Compensation. The fair value of options granted in 2014 to an executive was $22,000 which was expensed in 2014. As of December 31, 2014, there was no unrecognized compensation cost related to non-vested share-based compensation.
	The fair value of each option grant was estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions for 2014: dividend yield of 0%, expected volatility of 30%, risk-free interest rate of 0.90%, and weighted average expected lives of three years. The weighted average fair value per share of options granted for the year ended December 31, 2014 was $2.15.
	Following is a summary of stock options outstanding under both plans, adjusted for the stock splits that have occurred in prior years:
			Employee Stock Options
					Weighted		Aggregate
					Average		Intrinsic

	At December 31, 2014, stock options granted to employees were exercisable at a weighted average exercise price of $10.77. The range of exercise prices at December 31, 2014 for stock option plans was $9.86 - $11.65. The weighted average remaining contractual term for outstanding stock options was 34 months.
	The aggregate intrinsic value of all stock options and of all exercisable options at December 31, 2014 was $0.
Reclassification, Policy [Policy Text Block]	(l)	Reclassification
	Certain amounts in the 2013 consolidated financial statements have been reclassified to conform to the 2014 presentation
Advertising Costs, Policy [Policy Text Block]		(m)	Advertising
	Advertising costs are expensed as incurred.
Segment Reporting, Policy [Policy Text Block]	(n)	Operating segments
	ASC 280, “Segment Reporting”, provides guidance on the reporting and disclosure of information about operating segments. The Company is considered to have three principal business segments in 2014 and 2013, the Commercial/Retail bank, the Mortgage division, and the holding company. The Mortgage division began originating home mortgage loans through third parties and selling these loans to investors in late 2007. The Mortgage Division added a retail mortgage loan production office in July 2010 and another four retail mortgage loan production offices between 2012 and 2014. Retail mortgage loan officers are also located in five of eight full service bank offices. Financial performance for 2014 and 2013 and selected balance sheet information at December 31, 2014 and 2013 for each segment is shown in Note 16.
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
	On January 17, 2014, the FASB issued ASU 2014-04, Receivables—Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure (a consensus of the FASB Emerging Issues Task Force), to clarify when an in substance repossession or foreclosure occurs, and address the diversity in practice regarding when a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be reclassified as real estate property (i.e., taken possession of the real estate). Specifically, an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) obtaining legal title upon completion of a foreclosure or (2) obtaining interest in the property in satisfaction of the loan through a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the ASU requires interim and annual disclosure of both (1) the amount of foreclosed real estate held and (2) the recorded investment in mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The amendments will be effective for the Company on a prospective basis for interim and annual reporting periods beginning January 1, 2015. Early adoption and a modified retrospective application are permitted. These amendments are not expected to have a material effect on the Company’s statement of financial position.
	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), to provide guidance on accounting for investments by a reporting entity in flow-through limited liability entities that manage or invest in affordable housing projects that qualify for the low income housing tax credit. The ASU modifies the conditions that an entity must meet to be eligible to use a method other than the equity or cost methods to account for qualified affordable housing project investments. The ASU permits reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if those conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). Further, the decision to apply the proportional amortization method of accounting is an accounting policy decision that should be applied consistently to all qualifying affordable housing project investments rather than a decision to be applied to individual investments. An entity that has used the effective yield method to account for its investments in qualified affordable housing before the date of adoption may continue to apply the effective yield method for those preexisting investments. The amendments will be effective for the Company on a retrospective basis for interim and annual reporting periods beginning January 1, 2015. Early adoption is permitted. The Company has a $3 million qualified affordable housing investment of which $1,062,000 has been amortized through non-interest income over the past few years. The amount of amortization, which reduced non-interest income, was $315,000 and $217,000 for the years ending December 31, 2014 and 2013, respectively. Income tax credits which reduced income tax expense were $370,000 and $366,000 for the years ending December 31, 2014 and 2013, respectively. Under the proportional amortization method, part of the amortization which has reduced non-interest income would be reclassified to increase income tax expense. The Company does not expect these amendments to have a material effect on its financial statements.
	In August, 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. The ASU is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. In connection with preparing financial statements, management will need to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the organization’s ability to continue as a going concern within one year after the date that the financial statements are issued. The first management assessments are required in the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. These assessments and disclosures are not expected to have a material effect on the Company’s consolidated financial statements.
	In January, 2015, the FASB issued ASU No. 2015-01, Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items. The ASU eliminates the concept of extraordinary items from U.S. GAAP. Existing U.S. GAAP required that an entity separately classify, present, and disclose extraordinary events and transactions. Presently, an event or transaction is presumed to be an ordinary and usual activity of the reporting entity unless the event or transaction is both unusual in nature and infrequent in occurrence. The amendments will eliminate the requirements for reporting entities to consider whether an underlying event or transaction is extraordinary, however, the presentation and disclosure guidance for items that are unusual in nature or occur infrequently will be retained and will be expanded to include items that are both unusual in nature and infrequently occurring. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. The amendments may be applied either prospectively or retrospectively to all prior periods presented in the financial statements. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. These amendments are not expected to have a material effect on the Company’s statement of financial position.
	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 will be effective for the Company for reporting period beginning with the first quarter of 2015. The Company will apply the guidance by making a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. The Company does not expect these amendments to have a material effect on its 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, 2016. The Company does not expect these amendments to have a material effect on its financial statements.
	In January 2014, the FASB amended 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 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 period beginning after December 15, 2014, with early implementation of the guidance permitted. In implementing this guidance, assets that are reclassified from real estate to loans are measured at the carrying value of the real estate at the date of adoption. Assets reclassified from loans to real estate are measured at the lower of the net amount of the loan receivable or the fair value of the real estate less costs to sell at the date of adoption. The Company does not expect these amendments to have a material effect on its 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 December 31, 2014. The FASB proposal on Current Expected Credit Loss (“CECL”) is expected to be released in 2015 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 current historical loss rate method currently used to calculate the allowance for loan losses.

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, 2014 and 2013. 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.
