Earnings Per Share [Abstract]
Earnings Per Share [Text Block]	Note F - Earnings per common share
	Earnings per common share has been determined on a basic basis and a diluted basis which considers potential stock issuances. For the quarters ended March 31, 2015 and 2014, basic earnings per common share has been computed based upon the weighted average common shares outstanding of 3,434,680 and 3,428,891, respectively.
	The only potential issuances of Company stock are stock options granted to various officers of the Bank and the expected conversion of convertible preferred stock which was sold in a private placement offering on March 31, 2015. The 15,500 outstanding shares of the Company’s Series B convertible preferred stock are expected to be converted to 1,550,000 shares of common stock on May 22, 2015, subject to stockholder approval on May 19, 2015. The additional common shares of 1,550,000 were included in diluted weighted shares for one day in the first quarter of 2015. The following is a summary of the diluted earnings per common share calculation for the three months ended March 31, 2015 and 2014.
		Three Months Ended

	For the three months ended March 31, 2015 and 2014, there were stock options covering 75,220 and 70,620 shares, respectively, that were excluded in computing diluted common shares outstanding given that they were anti-dilutive since the exercise price exceeded the average market price for the period.

Equity [Abstract]
Preferred Stock [Text Block]	Note G – Preferred stock and convertible 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, Series A, 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 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, prior to 2014, using the effective yield method, thereby increasing preferred stock dividends. Dividends at 5% per annum were payable quarterly for the first five years; the dividend increased to 9% per annum after the fifth year effective February 16, 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 had 10,994 shares outstanding with an aggregate liquidation value of $10,994,000 at March 31, 2015. The remaining shares of Series A preferred stock were retired in May of 2015 using the proceeds from the private placement of Series B convertible preferred stock, which closed on March 31, 2015.
	On March 31, 2015, the Company issued 15,500 shares of Series B convertible preferred stock at $975 per share in a private placement offering and received $14,103,000 in net proceeds after offering expenses of $1,010,000. The net proceeds from this private placement were used to retire the remaining shares of Series A preferred stock in May of 2015 and to improve capital levels. The Series B convertible preferred stock has a fixed dividend of 9% per annum, which is payable semiannually after declaration by the Board of Directors, beginning September 30, 2015. Each share of Series B convertible preferred stock is convertible into one hundred shares of common stock automatically following shareholder approval. Shareholder approval of the conversion of all of the convertible preferred stock is anticipated at the upcoming annual meeting of shareholders on May 19, 2015. If approved by shareholders, the conversion from preferred to common stock should occur on or about May 22, 2015 and will not require the payment of any preferred stock dividends for the period outstanding.

Subordinated Borrowings [Abstract]
Subordinated Borrowings Disclosure [Text Block]	Note H – 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 principles governing Consolidated Variable Interest Entities. 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 at any time.
	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 credit and general creditors.

	The mortgage banking division experienced strong growth in originations from 2007 through 2012 due to low interest rates and due to the purchase of a retail loan production office in July of 2010. Origination of home mortgage loans has been volatile over the past few years and is dependent on a number of factors including the level of interest rates, general economic conditions, real estate values, and underwriting criteria to qualify borrowers. Mortgage loan originations were $166.4 million, $98.1 million, and $290.3 million for the first quarters of 2015, 2014 and 2013, respectively. 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 minimized 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 were established in 2009 to provide for potential claims that might arise from borrower fraud or underwriting errors. Warranty expenses were $43,000 and $32,000 for the three months ended March 31, 2015 and 2014, respectively. The warranty liability, which is available to fund future warranty claims, was $1,483,000 and $1,440,000 at March 31, 2015 and December 31, 2014, 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 banking division in 2007. In addition, seven loans with a total current carrying balance, including fair value loss adjustments recorded when transferred, of $1,605,000 have been repurchased and are included in loans held for investment.

	The Company sold two municipal securities with a total book value of $1,268,000 at a $27,000 gain during the first quarter of 2015.
	Securities with a carrying value of approximately $24,240,000 and $4,595,000 were pledged to secure retail repurchase agreements and certain deposits at March 31, 2015 and 2014, respectively.
	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 March 31, 2015, one corporate debt security with $972,000 in fair value, and three municipal securities with $3,473,000 in total fair value had total unrealized losses of $54,000. 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 March 31, 2015 and December 31, 2014, by category and length of time that individual securities have been in a continuous loss position follows:

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 March 31, 2015 and December 31, 2014:

	·	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.

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 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.

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 reserves required in the allowance for loan losses related to these loans. Troubled debt restructurings can be removed from such status and returned to non-impaired status in years subsequent to restructure if the interest rate charged at restructure was greater than or equal to the rate charged for a new extension of credit with comparable risk and if the loan is performing and there is no available information to indicate that performance will not continue.
No newly restructured loans occurred during the three months ended March 31, 2015 or 2014.
There were no troubled debt restructurings with a payment default, with the payment default occurring within 12 months of the restructure date, and the payment default occurring during the three months ended March 31, 2015 and 2014.
Troubled debt restructuring defaults can result in a higher allowance for loan losses and a corresponding higher provision for loan losses because defaults generally negatively impact the timing of and expected collections from these impaired loans. Impaired loans, which include troubled debt restructurings, are evaluated for specific additions to the allowance for loan losses by subtracting the recorded investment in these impaired loans from their fair values. Fair value is generally determined by the present value of future cash flows, collateral value, or liquidation value. Defaults generally reduce the present value of the future cash flows and can negatively impact the collateral values if declining real estate values are impacting the sale of collateral.
Loans secured by one to four family residential properties with unpaid principal balances of $693,000 at March 31, 2015 were in the process of foreclosure. These loans have been evaluated for impairment and related allowances for loan losses have been made where collateral values are less than principal loan balances.

Fair Value Measurements [Abstract]
Fair Value, Measurement Inputs, Disclosure [Text Block]	Note L – Fair value measurements
	The Company has adopted the accounting standards within FASB Accounting Standards Codification (ASC) 820 “Fair Value Measurements and Disclosures”, 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, U.S. Treasury securities and certain corporate bonds that are traded by dealers or brokers in active over-the-counter markets and money market funds. Level 2 securities include mortgage-backed securities issued by government sponsored entities, municipal bonds and most corporate debt securities. Securities classified as Level 3 include asset-backed securities and corporate debt securities in less liquid markets.
	Loans Held for Sale
	The Company opted to account for loans held for sale at fair value which is measured based on what secondary markets are currently offering for portfolios with similar characteristics. As such, the Company classifies loans subject to recurring fair value adjustments as Level 2 valuation.
	Interest Rate Lock Commitments
	The mortgage banking division of the Company sells most of its residential mortgage loans held for sale on a forward best efforts basis at a fixed price at approximately the same time as a fixed rate is given to borrowers. The value of the estimated loan sale commitments were marked to market through the income statement during the first quarter of 2015. The significant unobservable input used in the Level 3 fair value measurement of the Company’s Interest Rate Lock Commitments (IRLCs) on loans held for sale is the closing ratio, which represents the percentage of loans currently in a lock position which management estimates will ultimately close. The closing ratio is largely dependent on loan processing stages and the change in prevailing interest rates from the time of the rate lock. The closing ratio is computed by management using historical data.
	The fair value of interest rate lock commitments is based on servicing rate premium, origination income net of origination costs, fall out rates and changes in loan pricing due to delays in meeting commitment closing dates. The Company classifies interest rate lock commitments as Level 3. Gain or loss on interest rate lock commitments for the period is included in mortgage banking income of non-interest income on the Consolidated Statements of Income. The mortgage banking division resumed reporting IRLCs in the first quarter of 2015 after having suspended recognition in 2014 due to immateriality. Below is a summary of activity related to interest rate lock commitments for the three months ended March 31, 2015 and 2014.

	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 March 31, 2015 and December 31, 2014, a majority of the total impaired loans were evaluated based on the fair value of the collateral. When the fair value of the collateral is based on an executed sales contract with an independent third party, the Company records the impaired loans as nonrecurring Level 1. If the collateral is based on another observable market price or a current appraised value, the Company records the impaired loans as nonrecurring Level 2. When an appraised value is not available or the Company determines the fair value of the collateral is further impaired below the appraised value and there is no observable market price, the Company records the impaired loan as nonrecurring Level 3. Impaired loans can also be evaluated for impairment using the present value of expected future cash flows discounted at the loan’s effective interest rate. The measurement of impaired loans using future cash flows discounted at the loan’s effective interest rate rather than the market rate of interest is not a fair value measurement and is therefore excluded from fair value disclosure requirements. Impaired loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly.
	Other Real Estate Owned and Repossessed Assets
	Properties acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value less costs to sell at the date of foreclosure. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying value or the new fair value less estimated selling costs. Fair value is generally based upon current appraisals, comparable sales, and other estimates of value obtained principally from independent sources, adjusted for selling costs. When the fair value of the collateral is based on an observable market price or a current appraised value, the Company records the asset as nonrecurring Level 2. However, the Company also considers other factors or recent developments which could result in adjustments to the collateral value estimates indicated in the appraisals such as changes in absorption rates or market conditions from the time of valuation. In situations where an appraisal less estimated selling costs is used to determine fair value, management adjustments are significant to the fair value measurements, or other means are used to estimate fair value in the absence of an appraisal, the Company records the impaired loan as nonrecurring Level 3 within the valuation hierarchy.
	Assets measured at fair value on a non-recurring basis at March 31, 2015 and December 31, 2014 are summarized below:

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 March 31, 2015, there were no fair value adjustments related to $15,313,000 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 debt was determined by discounting cash flows using a rate 300 basis points higher than the actual current rate over an estimated remaining term of 12.25 years in 2015 and 12.50 years in 2014. The trust preferred debt was issued at favorable rates in 2004, and current rates are approximately 300 basis points higher when available. The Basel III capital guidelines allow for inclusion of trust preferred securities as Tier 1 capital, up to certain “quantitative limits” for banks with less than $5 billion in consolidated assets.
The following table presents the carrying amount, fair value, and placement in the fair value hierarchy of financial instruments at March 31, 2015 and December 31, 2014. This table excludes financial instruments for which the carrying amount approximates fair value. For short-term financial assets such as cash and due from banks and interest-bearing deposits with banks, the carrying amount is a reasonable estimate of fair value due to the relatively short time between the origination of the instrument and its expected realization. For financial liabilities such as non-interest bearing demand deposits, NOW, money market and savings deposits, the carrying amount is a reasonable estimate of fair value due to these products having no stated maturity.

Derivatives and Financial Instruments [Abstract]

Derivative Instruments and Hedging Activities Disclosure [Text Block]

Note M – Derivatives and financial instruments

A derivative is a financial instrument or arrangement that derives its cash flows and value by reference to an underlying instrument, index or referenced interest rate. These instruments are designed to hedge exposures to interest rate risk or for speculative purposes.

Accounting guidance requires an entity to recognize all derivatives as either assets or liabilities in the balance sheet, and measure those instruments at fair value. Changes in the fair value of those derivatives are reported in current earnings or other comprehensive income depending on the purpose for which the derivative is held and whether the derivative qualifies for hedge accounting.

The Company currently sells mortgage loans, 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 March 31, 2015 and December 31, 2014:

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 operations. 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 operations during the three months ended March 31, 2015 and 2014, 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.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	Note N – Impact of recently adopted accounting standards
	On January 15, 2014, the FASB issued ASU 2014-01, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects (a consensus of the FASB Emerging Issues Task Force), 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 were effective for the Company on a retrospective basis for interim and annual reporting periods beginning January 1, 2015. The Company has a $3 million qualified affordable housing investment of which $1.1 million has been amortized through non-interest income using the effective yield method which approximates the proportional amortization method. These amendments did not have a material effect on the Company’s 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 were effective for the Company for the reporting period beginning with the first quarter of 2015. The amendments did not have a material effect on the Company’s financial statements.
	In May 2014, the FASB issued guidance to change the recognition of revenue from contracts with customers. The core principle of the new guidance is that an entity should recognize revenue to reflect the transfer of goods and services to customers in an amount equal to the consideration the entity receives or expects to receive. The guidance will be effective for the Company for reporting periods beginning after December 15, 2017. 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 to reclassify a collateralized consumer mortgage loan to OREO upon obtaining legal title to the real estate collateral, or the borrower voluntarily conveying all interest in the real estate property to the lender to satisfy the loan through a deed in lieu of foreclosure or similar legal agreement. The amendments will be effective for the Company for annual periods, and interim periods within those annual periods beginning after December 15, 2014, 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. 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. These amendments did not have a material effect on the Company’s financial statements.
	In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis, which amends the consolidation requirements in Accounting Standards Codification (ASC) 810, Consolidation, and significantly changes the consolidation analysis required under U.S. GAAP. The amendments include the following:
		•	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, for investments in certain investment funds has been eliminated.
	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 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 March 31, 2015. 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.

Commitments and Contingencies Disclosure [Text Block],	Note O - Commitments
	In the normal course of business there are outstanding commitments for the extension of credit which are not reflected in the financial statements. At March 31, 2015 and December 31, 2014, pre-approved but unused lines of credit for loans totaled approximately $163,111,000 and $174,665,000, respectively. In addition, we had $1,047,000 and $1,812,000 in standby letters of credit at March 31, 2015 and December 31, 2014, respectively. These commitments represent no more than the normal lending risk that we commit to borrowers. If these commitments are drawn, we will obtain collateral if it is deemed necessary based on our credit evaluation of the counter-party. We believe these commitments can be funded through normal operations.
	The Company leases land for its main office, four loan production offices, and two branch facilities under operating leases. The Friendly Avenue Branch in Greensboro is expected to close at the end of July 2015 due to the expiration of the related lease in December 2015.
	Total future minimum lease payments, excluding renewal options, at March 31, 2015 under the leases are as follows:

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