Basis of Presentation [Abstract]
Basis of Presentation	Note 1 – Basis of Presentation
	The consolidated financial statements include the accounts of American National Bankshares Inc. (the "Company") and its wholly owned subsidiary, American National Bank and Trust Company (the "Bank").  The Bank offers a wide variety of retail, commercial, secondary market mortgage lending, and trust and investment services which also include non-deposit products such as mutual funds and insurance policies.
	The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. 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, the valuation of foreclosed real estate, goodwill and intangible assets, the valuation of deferred tax assets, other-than-temporary impairments of securities, and acquired loans with specific credit-related deterioration.
	All significant inter-company transactions and accounts are eliminated in consolidation, with the exception of the AMNB Trust and the MidCarolina Trusts, as detailed in Note 9.
	In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments (consisting of normal recurring accruals) necessary to present fairly the results of the interim periods. The results of operations for the interim periods are not necessarily indicative of the results that may occur for the year ending December 31, 2015.  Certain reclassifications have been made to prior period balances to conform to the current period presentation. These reclassifications did not have an impact on net income and were considered immaterial. These statements should be read in conjunction with the Notes to Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2014.

Merger with MainStreet[Abstract]
Merger with MainStreet	Note 2 – Merger with MainStreet
	On January 1, 2015, the Company completed its acquisition of MainStreet BankShares, Inc. ("MainStreet"). The merger of MainStreet with and into the Company was effected pursuant to the terms and conditions of the Agreement and Plan of Reorganization, dated as of August 24, 2014, between the Company and MainStreet, and a related Plan of Merger. Immediately after the merger, Franklin Community Bank, N.A., MainStreet's wholly owned bank subsidiary, merged with and into the Bank.  Pursuant to the MainStreet merger agreement, holders of shares of MainStreet common stock received $3.46 in cash and 0.482 shares of the Company's common stock for each share of MainStreet common stock held immediately prior to the effective date of the merger, plus cash in lieu of fractional shares.  Each option to purchase shares of MainStreet common stock that was outstanding immediately prior to the effective date of the merger vested upon the merger and was converted into an option to purchase shares of the Company's common stock, adjusted based on a 0.643 exchange ratio. Each share of the Company's common stock outstanding immediately prior to the merger remained outstanding and was unaffected by the merger. The cash portion of the merger consideration was funded through a cash dividend of $6,000,000 from the Bank to the Company, and no borrowing was incurred by the Company or the Bank in connection with the merger. Replacement stock option awards representing 43,086 shares of the Company's common stock were granted in conjunction with the MainStreet acquisition.  The value of the consideration transferred with the replacement awards was not determined as of March 31, 2015; therefore, the amounts of the consideration transferred and goodwill recorded in connection with the merger will be adjusted for the value of the replacement awards in the second quarter of 2015.
	The transaction was accounted for using the acquisition method of accounting and, accordingly, assets acquired, liabilities assumed, and consideration exchanged were recorded at estimated fair values on the acquisition date. Fair values are preliminary and subject to refinement for up to one year after the closing date of the acquisition.
	In connection with the merger, the consideration paid, and the fair value of identifiable assets acquired and liabilities assumed as of the merger date are summarized in the following table (dollars in thousands).
	Consideration Paid:
	Common shares issued (825,586)	$	20,483
	Cash paid to shareholders		5,935
	Value of consideration		26,418
	Assets acquired:

	Premises and equipment		1,475

	Core deposit intangible		1,839
	Other real estate owned		168
	Banked owned life insurance		1,955
	Other assets		917
	Total assets		161,650
	Liabilities assumed:
	Deposits		137,323
	Other liabilities		3,076
	Total liabilities		140,399
	Net assets acquired		21,251
	Goodwill resulting from merger with MainStreet	$	5,167
	In many cases, the fair values of assets acquired and liabilities assumed were determined by estimating the cash flows expected to result from those assets and liabilities and discounting them at appropriate market rates. The most significant category of assets for which this procedure was used was that of acquired loans. The Company acquired the $122,300,000 loan portfolio at a fair value discount of $7,400,000. The estimated fair value of the performing portion of the portfolio was $105,800,000. The excess of expected cash flows above the fair value of the performing portion of loans will be accreted to interest income over the remaining lives of the loans in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 310-20.
	Certain loans, those for which specific credit-related deterioration since origination was identified, are recorded at fair value, reflecting the present value of the amounts expected to be collected. Income recognition on these loans is based on reasonable expectations about the timing and amount of cash flows to be collected. Acquired loans deemed impaired and considered collateral dependent, with the timing of the sale of loan collateral indeterminate, remain on non-accrual status and have no accretable yield.
	The following table details the acquired loans that are accounted for in accordance with FASB ASC 310-30 as of January 1, 2015 (dollars in thousands).
	Contractually required principal and interest at acquisition	$	13,504
	Contractual cash flows not expected to be collected (nonaccretable difference)		3,298
	Expected cash flows at acquisition		10,206
	Interest component of expected cash flows (accretable yield)		1,208
	Fair value of acquired loans accounted for under FASB ASC 310-30	$	8,998
	In accordance with GAAP, there was no carryover of the allowance for loan losses that had been previously recorded by MainStreet.
	In connection with the merger with MainStreet, the Company acquired an investment portfolio with a fair value of $18,800,000. The fair value of the investment portfolio was determined by taking into account market prices obtained from independent valuation sources.
	In connection with the merger with MainStreet, the Company recorded a deferred income tax asset of $2,700,0000 related to tax attributes of MainStreet, along with the effects of fair value adjustments resulting from applying the acquisition method of accounting.
	In connection with the merger with MainStreet, the Company acquired other real estate owned with a fair value of $168,000. Other real estate owned was measured at fair value less estimated cost to sell.
	In connection with the merger with MainStreet, the Company acquired premises and equipment with a fair value of $1,400,000.
	The fair value of savings and transaction deposit accounts acquired from MainStreet was assumed to approximate their carrying value as these accounts have no stated maturity and are payable on demand. Certificates of deposit accounts were valued by comparing the contractual cost of the portfolio to an identical portfolio bearing current market rates. The portfolio was segregated into pools based on segments: retail, individual retirement accounts, and brokered. For each segment, the projected cash flows from maturing certificates were then calculated based on contractual rates and prevailing market rates. The valuation adjustment for each segment is equal to the present value of the difference of these two cash flows, discounted at the assumed market rate for a certificate with a corresponding maturity. This valuation adjustment of $290,000 will be accreted to reduce interest expense over the average remaining maturities of the respective pools, which is estimated to be 12 months.
	A core deposit intangible of $1,800,000 was recognized in connection with the merger with MainStreet. This intangible will be amortized over a 10 year period on an accelerated cost recovery basis.
	Direct costs related to the acquisition were expensed as incurred. During the entire year of 2011, the Company incurred $359,000 in merger and acquisition expenses.
	The following table presents unaudited pro forma information as if the merger with MainStreet had occurred on January 1, 2014. This pro forma information gives effect to certain adjustments, including purchase accounting fair value adjustments, amortization of core deposit intangible and related income tax effects. The pro forma information does not necessarily reflect the results of operations that would have occurred had the merger with MainStreet occurred in 2014.  In particular, expected operational cost savings are not reflected in the pro forma amounts (dollars in thousands):.

	Restricted Stock
	Due to restrictions placed upon the Bank's common stock investment in the Federal Reserve Bank of Richmond ("FRB") and Federal Home Loan Bank of Atlanta ("FHLB"), these securities have been classified as restricted equity securities and carried at cost.  The restricted securities are not subject to the investment security classification and are included as a separate line item on the Company's balance sheet.  The FRB requires the Bank to maintain stock with a par value equal to 6.0% of its common stock and paid-in surplus.  One-half of this amount is paid to the FRB and the remaining half is subject to call when deemed necessary by the Board of Governors of the Federal Reserve System.  The FHLB requires the Bank to maintain stock in an amount equal to a specific percentage of the Bank's total assets and 4.5% of outstanding borrowings. The Bank also owns common stock in CBB Financial Corporation and Pacific Coast Bankers Bankshares, which both provide services to community banks. The cost of restricted stock at March 31, 2015 and December 31, 2014 were as follows (dollars in thousands):
		March 31,		December 31,
		2015		2014

	Temporarily Impaired Securities
	The following table shows fair value and gross unrealized losses, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, at March 31, 2015.  The reference point for determining when securities are in an unrealized loss position is month-end.  Therefore, it is possible that a security's market value exceeded its amortized cost on other days during the past twelve-month period (dollars in thousands).

	Federal Agencies and GSE debt securities: The unrealized losses on the Company's investment in four government sponsored entities ("GSE") were caused by interest rate increases. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost basis of the investments. Because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost basis, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at March 31, 2015.
	Mortgage-backed securities and CMOs: The unrealized losses on the Company's investment in 13 GSE mortgage-backed securities and collateralized mortgage obligations ("CMOs") were caused by interest rate increases. The contractual cash flows of those investments are guaranteed by an agency of the U.S. Government. Accordingly, it is expected that the securities would not be settled at a price less than the amortized cost basis of the Company's investments. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost basis, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at March 31, 2015.
	State and municipal securities:  The unrealized losses on 14 state and municipal securities were caused by interest rate increases. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost basis of the investments. Because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost basis, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at March 31, 2015.
	Corporate securities:  The unrealized losses on three investments in corporate securities were caused by interest rate increases. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost basis of the investments. Because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost basis, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at March 31, 2015.
	Restricted stock: When evaluating restricted stock for impairment, its value is based on the ultimate recoverablity of the par value rather than by recognizing temporary declines in value. The company does not consider restricted stock to be other-than-temoraily impaired at March 31, 2015, and no impairment has been recognized.
	The table below shows gross unrealized losses and fair value, aggregated by investment category and length of time that individual securities had been in a continuous unrealized loss position, at December 31, 2014 (dollars in thousands):

Loans classified in the Pass category typically are fundamentally sound and risk factors are reasonable and acceptable.
Loans classified in the Special Mention category typically have been criticized internally, by loan review or the loan officer, or by external regulators under the current credit policy regarding risk grades.
Loans classified in the Substandard category typically have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt; they are typically characterized by the possibility that the Bank will sustain some loss if the deficiencies are not corrected.
Loans classified in the Doubtful category typically have all the weaknesses inherent in loans classified as substandard, plus the added characteristic that the weaknesses make collection or liquidation in full on the basis of currently existing facts, conditions, and values highly questionable and improbable. However, these loans are not yet rated as loss because certain events may occur that may salvage the debt.
Consumer loans are classified as performing or nonperforming.  A loan is nonperforming when payments of interest and principal are past due 90 days or more, or payments are less than 90 days past due, but there are other good reasons to doubt that payment will be made in full.

Goodwill and Other Intangible Assets [Abstract]
Goodwill and Other Intangible Assets	Note 6 – Goodwill and Other Intangible Assets
	The Company records as goodwill the excess of the purchase price over the fair value of the identifiable net assets acquired. Impairment testing is performed annually, as well as when an event triggering impairment may have occurred. The Company performs its annual analysis as of June 30 each fiscal year. Accounting guidance permits preliminary assessment of qualitative factors to determine whether more substantial impairment testing is required. The Company chose to bypass the preliminary assessment and utilized a two-step process for impairment testing of goodwill. The first step tests for impairment, while the second step, if necessary, measures the impairment.  No indicators of impairment were identified as of June 30, 2014.
	Core deposit intangibles resulting from the acquisition of Community First Financial Corporation ("Community First") in April 2006 were $6,556,000 and are being amortized over 108 months.  Core deposit intangibles resulting from the MidCarolina acquisition in July 2011 were $3,112,000 and are being amortized on an accelerated basis over 120 months. Core deposit intangibles resulting from the MainSteeet acquisition in January 2015 were $1,839,000 and are being amortized on an accelerated basis over 120 months.
	The changes in the carrying amount of goodwill and intangibles for the three months ended March 31, 2015, are as follows (dollars in thousands):
		Goodwill		Intangibles

Short-term Borrowings [Abstract]
Short-term Borrowings	Note 7 – Short-term Borrowings
	Short-term borrowings consist of customer repurchase agreements, overnight borrowings from the FHLB, and Federal Funds purchased.  Customer repurchase agreements are collateralized by securities of the U.S. Government or its agencies or GSEs.  They mature daily.  The interest rates may be changed at the discretion of the Company. The securities underlying these agreements remain under the Company's control.  Other short-term borrowings consist of overnight advances which contain floating interest rates that may change daily at the discretion of the FHLB.  Federal Funds purchased are unsecured overnight borrowings from other financial institutions. There were no customer repurchase agreements acquired in the MainStreet acquisition. Short-term borrowings consisted of the following at March 31, 2015 and December 31, 2014 (dollars in thousands):
		31-Mar-15			31-Dec-14

Note 8 – Long-term Borrowings

Under the terms of its collateral agreement with the FHLB, the Company provides a blanket lien covering all of its residential first mortgage loans, second mortgage loans, home equity lines of credit, and commercial real estate loans.  In addition, the Company pledges as collateral its capital stock in the FHLB and deposits with the FHLB.  The Company has a line of credit with the FHLB equal to 30% of the Company's assets, subject to the amount of collateral pledged.  As of March 31, 2015, $405,936,000 in eligible collateral was pledged under the blanket floating lien agreement which covers both short-term and long-term borrowings.  Long-term borrowings consisted of the following fixed rate, long-term advances as of March 31, 2015 and December 31, 2014 (dollars in thousands):

The advance due in November 2017 is net of a fair value discount of $59,000. The original discount recorded on July 1, 2011, was a result of the merger with MidCarolina. The adjustment to the face value will be amortized into interest expense over the life of the borrowing. There were no long-term borrowings acquired in the MainStreet acquisition and no borrowings were incurred to fund the acquisition.

In the regular course of conducting its business, the Company takes deposits from political subdivisions of the states of Virginia and North Carolina. At March 31, 2015, the Bank's public deposits totaled $136,218,000.  The Company is required to provide collateral to secure the deposits that exceed the insurance coverage provided by the Federal Deposit Insurance Corporation. This collateral can be provided in the form of certain types of government or agency bonds or letters of credit from the FHLB. At March 31, 2015, the Company had $70,000,000 in letters of credit with the FHLB outstanding, as well as $116,655,000 in agency, state, and municipal securities to provide collateral for such deposits.

On April 7, 2006, AMNB Statutory Trust I (the "AMNB Trust I"), a Delaware statutory trust and a wholly owned subsidiary of the Company, issued $20,000,000 of preferred securities (the "Trust Preferred Securities") in a private placement pursuant to an applicable exemption from registration.  The Trust Preferred Securities mature on September 30, 2036, but may be redeemed at the Company's option (which option became effective beginning on September 30, 2011).  Initially, the securities required quarterly distributions by the AMNB Trust I to the holder of the Trust Preferred Securities at a fixed rate of 6.66%.  Effective September 30, 2011, the rate resets quarterly at the three-month LIBOR plus 1.35%.  Distributions are cumulative and will accrue from the date of original issuance, but may be deferred by the Company from time to time for up to 20 consecutive quarterly periods.  The Company has guaranteed the payment of all required distributions on the Trust Preferred Securities.

The proceeds of the Trust Preferred Securities received by the AMNB Trust, along with proceeds of $619,000 received by the trust from the issuance of common securities by the trust to the Company, were used to purchase $20,619,000 of the Company's junior subordinated debt securities (the "Trust Preferred Capital Notes"), issued pursuant to junior subordinated debentures entered into between the Company and Wilmington Trust Company, as trustee.  The proceeds of the Trust Preferred Capital Notes were used to fund the cash portion of the merger consideration to the former shareholders of Community First in connection with the Company's acquisition of that company, and for general corporate purposes.

On July 1, 2011, in connection with the MidCarolina merger, the Company assumed $8,764,000 in junior subordinated debentures to MidCarolina Trust I and MidCarolina Trust II, two separate Delaware statutory trusts (the "MidCarolina Trusts"), to fully and unconditionally guarantee the preferred securities issued by the MidCarolina Trusts. These long-term obligations, which currently qualify as Tier 1 capital, constitute a full and unconditional guarantee by the Company of the MidCarolina Trusts' obligations. The MidCarolina Trusts are not consolidated in the Company's financial statements.

In accordance with FASB ASC 810-10-15-14, the Company did not eliminate through consolidation the Company's $619,000 equity investment in AMNB Trust I or the $264,000 equity investment in the MidCarolina Trusts.  Instead, the Company reflected this equity investment in the "Accrued interest receivable and other assets" line item in the consolidated balance sheets.

A description of the junior subordinated debt securities outstanding payable to the trusts is shown below as of  March 31, 2015 and December 31, 2014 (dollars in thousands):

Stock-Based Compensation [Abstract]
Stock-Based Compensation	Note 10 – Stock Based Compensation
	The Company's 2008 Stock Incentive Plan ("2008 Plan") was adopted by the Board of Directors of the Company on February 19, 2008, and approved by shareholders on April 22, 2008, at the Company's 2008 Annual Meeting of Shareholders.  The 2008 Plan provides for the granting of restricted stock awards and incentive and non-statutory options to employees and directors on a periodic basis, at the discretion of the Board of Directors or a Board designated committee.  The 2008 Plan authorizes the issuance of up to 500,000 shares of common stock. The 2008 Plan replaced the Company's stock option plan that was approved by the shareholders at the 1997 Annual Meeting. The prior stock option plan was terminated in 2006.
	Stock Options
	Accounting guidance requires that compensation cost relating to share-based payment transactions be recognized in the financial statements with measurement based upon the fair value of the equity or liability instruments issued.
	A summary of stock option transactions for the three months ended March 31, 2015 is as follows:
		Option		Weighted		Weighted	Aggregate

	Replacement stock option awards representing 43,086 shares of the Company's common stock were granted in conjunction with the MainStreet acquisition.  The value of the consideration transferred with the replacement awards was not determined as of March 31, 2015; therefore, the amounts of the consideration transferred and goodwill recorded in connection with the merger will be adjusted for the value of the replacement awards in the second quarter of 2015.
	The fair value of options is estimated at the date of grant using the Black-Scholes option pricing model and expensed over the options' vesting period.  As of March 31, 2015, there was no unrecognized compensation expenses related to nonvested stock option grants.
	Restricted Stock
	The Company from time-to-time grants shares of restricted stock to key employees and non-employee directors.  These awards help align the interests of these employees and directors with the interests of the shareholders of the Company by providing economic value directly related to increases in the value of the Company's common stock.  The value of the stock awarded is established as the fair market value of the stock at the time of the grant.  The Company recognizes expense, equal to the total value of such awards, ratably over the vesting period of the stock grants. Restricted stock granted cliff vests over 24 to 36 months based on the term of the award.
	Nonvested restricted stock activity for the three months ended March 31, 2015 is summarized in the following table.
	Restricted Stock	Shares		Weighted Average Grant Date Value
	Nonvested at December 31, 2014		41,562	$	21.39

	Vested		15,536		19.51
	Forfeited		-		-
	Nonvested at March 31, 2015		42,675	$	18.77
	As of March 31, 2015 and December 31, 2014, there was  $594,000 and $327,000 in unrecognized compensation cost related to nonvested restricted stock granted under the 2008 Plan.  The weighted average period over which this cost is expected to be recognized is 1.77 years.   The share based compensation expense for nonvested restricted stock was $93,000 and $70,000 during the first three months of 2015 and 2014, respectively.
	Starting in 2010, the Company began offering its outside directors alternatives with respect to director compensation. The regular quarterly board retainer can be received in the form of either (i) $1,000 in cash or (ii) shares of immediately vested, but restricted stock with a market value of $1,563. Monthly meeting fees can also be received as $600 per meeting in cash or $750 in immediately vested, but restricted stock.  For 2015, all 13 outside directors have elected to receive stock in lieu of cash for either all or part of their quarterly retainer or meeting fees. Only outside directors receive board fees. The Company issued 2,812 and 3,002 shares and recognized share based compensation expense of $155,000 and $96,000 during the first three months of 2015 and 2014, respectively.

	The Company has two reportable segments, (i) community banking and (ii) trust and investment services.
	Community banking involves making loans to and generating deposits from individuals and businesses.  All assets and liabilities of the Company are allocated to community banking.  Investment income from securities is also allocated to the community banking segment.  Loan fee income, service charges from deposit accounts, and non-deposit fees such as automated teller machine fees and insurance commissions generate additional income for the community banking segment.
	Trust and investment services include estate planning, trust account administration, investment management, and retail brokerage.  Investment management services include purchasing equity, fixed income, and mutual fund investments for customer accounts. The trust and investment services segment receives fees for investment and administrative services.
	Amounts shown in the "Other" column includes activities of the Company which are primarily debt service on trust preferred securities and corporate items.  Intersegment eliminations primarily consist of the Company's investment in the Bank.

Fair_Value_of_Financial_Instru

Fair Value of Financial Instruments [Abstract]
Fair Value of Financial Instruments	Note 14 – Fair Value of Financial Instruments
	Determination of Fair Value
	The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. In accordance with the fair value measurements and disclosures topic of FASB ASC 820, "Fair Value Measurement and Disclosures", the fair value of an instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company's various instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument.
	The fair value guidance provides a consistent definition of fair value, which focuses on exit price in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions.
	Fair Value Hierarchy
	In accordance with this guidance, the Company groups its assets and liabilities generally measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value.
		Level 1 –	Valuation is based on quoted prices in active markets for identical assets and liabilities.
		Level 2 –	Valuation is based on observable inputs including quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets and liabilities in less active markets, and model-based valuation techniques for which significant assumptions can be derived primarily from or corroborated by observable data in the market.
		Level 3 –	Valuation is based on model-based techniques that use one or more significant inputs or assumptions that are unobservable in the market.
	The following describes the valuation techniques used by the Company to measure certain assets and liabilities recorded at fair value on a recurring basis in the financial statements:
	Securities available for sale: Securities available for sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted market prices, when available (Level 1). If quoted market prices are not available, fair values are measured utilizing independent valuation techniques of identical or similar securities for which significant assumptions are derived primarily from or corroborated by observable market data. Third party vendors compile prices from various sources and may determine the fair value of identical or similar securities by using pricing models that consider observable market data (Level 2). If no observable market data is available, valuations are based upon third party model based techniques (Level 3).  FRB and FHLB stocks are carried at cost since no ready market exists and there is no quoted market value.  The Company is required to own stock in these entities as long as it is a member.  Therefore, they have been excluded from the following table.
	The following table presents the balances of assets and liabilities measured at fair value on a recurring basis during the period (dollars in thousands):

	Certain assets are measured at fair value on a nonrecurring basis in accordance with GAAP. Adjustments to the fair value of these assets usually result from the application of lower-of-cost-or-market accounting or write-downs of individual assets.
	The following describes the valuation techniques used by the Company to measure certain assets recorded at fair value on a nonrecurring basis in the financial statements:
	Loans held for sale: Loans held for sale are carried at estimated fair value. These loans currently consist of one-to-four family residential loans originated for sale in the secondary market. Fair value is based on the price secondary markets are currently offering for similar loans using observable market data which is not materially different than cost due to the short duration between origination and sale (Level 2). As such, the Company records any fair value adjustments on a nonrecurring basis. No nonrecurring fair value adjustments were recorded on loans held for sale during the three month period ended March 31, 2015 or the year ended December 31, 2014. Gains and losses on the sale of loans are recorded within income from mortgage banking on the Consolidated Statements of Income.
	Impaired loans: Loans are designated as impaired when, in the judgment of management based on current information and events, it is probable that all amounts due according to the contractual terms of the loan agreements will not be collected.  In addition, the impairment of a loan may be measured using a present value of future cash flows analysis (Level 3). Collateral may be in the form of real estate or business assets including equipment, inventory, and accounts receivable.  The vast majority of the Company's collateral is real estate.  The value of real estate collateral is determined utilizing a market valuation approach based on an appraisal, of one year or less, conducted by an independent, licensed appraiser using observable market data (Level 2).  However, if the collateral is a house or building in the process of construction or if an appraisal of the property is more than one year old and not solely based on observable market comparables or management determines the fair value of the collateral is further impaired below the appraised value, then a Level 3 valuation is considered to measure the fair value.  The value of business equipment is based upon an outside appraisal, of one year or less, if deemed significant, or the net book value on the applicable business's financial statements if not considered significant using observable market data.  Likewise, values for inventory and accounts receivables collateral are based on financial statement balances or aging reports (Level 3).  Impaired loans allocated to the allowance for loan losses are measured at fair value on a nonrecurring basis.  Any fair value adjustments are recorded in the period incurred as provision for loan losses on the Consolidated Statements of Income.
	Other real estate owned:  Measurement for fair values for other real estate owned are the same as real estate collateral discussed with impaired loans.
	The following table summarizes the Company's assets that were measured at fair value on a nonrecurring basis at the dates indicated (dollars in thousands):

The following methods and assumptions were used by the Company in estimating fair value disclosures for financial instruments:
Cash and cash equivalents.  The carrying amount is a reasonable estimate of fair value.
Securities.  Fair values are based on quoted market prices or dealer quotes.
Loans held for sale.  The carrying amount is a reasonable estimate of fair value.
Loans.  For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values.  Fair values for fixed-rate loans are estimated based upon discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality.  Fair values for nonperforming loans are estimated using discounted cash flow analyses or underlying collateral values, where applicable.
Bank owned life insurance. Bank owned life insurance represents insurance policies on officers, directors, and past directors of the Company.  The cash values of the policies are estimates using information provided by insurance carriers.  These policies are carried at their cash surrender value, which approximates the fair value.
Accrued interest receivable.  The carrying amount is a reasonable estimate of fair value.
Deposits.  The fair value of demand deposits, savings deposits, and money market deposits equals the carrying value. The fair value of fixed-rate certificates of deposit is estimated by discounting the future cash flows using the current rates at which similar deposit instruments would be offered to depositors for the same remaining maturities.
Repurchase agreements.  The carrying amount is a reasonable estimate of fair value.
Other borrowings.  The fair values of other borrowings are estimated using discounted cash flow analyses based on the interest rates for similar types of borrowing arrangements.
Trust preferred capital notes.  Fair value is calculated by discounting the future cash flows using the estimated current interest rates at which similar securities would be issued.
Accrued interest payable.  The carrying amount is a reasonable estimate of fair value.
Off-balance sheet instruments.  The fair value of letters of credit is based on fees currently charged for similar agreements or on the estimated cost to terminate them or otherwise settle the obligations with the counterparties at the reporting date.  At March 31, 2015 and December 31, 2014, the fair value of off-balance sheet instruments was deemed immaterial, and therefore was not included in the previous table.
The Company assumes interest rate risk (the risk that interest rates will change) in its normal operations.  As a result, the fair values of the Company's financial instruments will change when interest rates change and that change may be either favorable or unfavorable to the Company.

Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	Note 17 – Recent Accounting Pronouncements
	In January 2014, the FASB issued Accounting Standards Update ("ASU")  No. 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)."  The amendments in this ASU permit reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain 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).  The amendments in this ASU should be applied retrospectively to all periods presented. A reporting entity that uses the effective yield method to account for its investments in qualified affordable housing projects before the date of adoption may continue to apply the effective yield method for those preexisting investments. The amendments in this ASU are effective for public business entities for annual periods and interim reporting periods within those annual periods, beginning after December 15, 2014. Early adoption is permitted. The adoption of the new guidance did not have a material impact on the Company's consolidated financial statements.
	In January 2014, the FASB issued ASU No. 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)."  The amendments in this ASU clarify that 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) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer 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 in this ASU are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014.  The adoption of the new guidance did not have a material impact on the Company's consolidated financial statements.
	In June 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers: Topic 606." This ASU applies to any entity using. GAAP that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards. The guidance supersedes the revenue recognition requirements in Topic 605, "Revenue Recognition", most industry-specific guidance, and some cost guidance included in Subtopic 605-35, "Revenue Recognition—Construction-Type and Production-Type Contracts." The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To be in alignment with the core principle, an entity must apply a five step process including: identification of the contract(s) with a customer, identification of performance obligations in the contract(s), determination of the transaction price, allocation of the transaction price to the performance obligations, and recognition of revenue when (or as) the entity satisfies a performance obligation.  Additionally, the existing requirements for the recognition of a gain or loss on the transfer of nonfinancial assets that are not in a contract with a customer have also been amended to be consistent with the guidance on recognition and measurement.  The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted. In April 2015, the FASB voted in favor of a one year deferral of the effective date of this amendment.  An exposure draft is expected with a 30 day comment period. The Company is currently assessing the impact that ASU 2014-09 will have on its consolidated financial statements.
	In June 2014, the FASB issued ASU No. 2014-10, "Development Stage Entities (Topic 915): Elimination of Certain Financial Reporting Requirements, Including an Amendment to Variable Interest Entities Guidance in Topic 810, Consolidation." The amendments in this ASU remove all incremental financial reporting requirements from GAAP for development stage entities, including the removal of Topic 915, "Development Stage Entities," from the FASB Accounting Standards Codification. In addition, this ASU adds an example disclosure and removes an exception provided to development stage entities in Topic 810, "Consolidation," for determining whether an entity is a variable interest entity.  The presentation and disclosure requirements in Topic 915 will no longer be required for the first annual period beginning after December 15, 2014. The revised consolidation standards are effective for annual periods beginning after December 15, 2015.  Early adoption is permitted. The Company does not expect the adoption of ASU 2014-10 to have a material impact on the Company's consolidated financial statements.
	In June 2014, the FASB issued ASU No. 2014-11, "Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures."  This ASU aligns the accounting for repurchase-to-maturity transactions and repurchase agreements executed as a repurchase financing with the accounting for other typical repurchase agreements. The new guidance eliminates sale accounting for repurchase-to-maturity transactions and supersedes the guidance under which a transfer of a financial asset and a contemporaneous repurchase financing could be accounted for on a combined basis as a forward agreement. The amendments in the ASU also require a new disclosure for transactions economically similar to repurchase agreements in which the transferor retains substantially all of the exposure to the economic return on the transferred financial assets throughout the term of the transaction. Additional disclosures will be required for the nature of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings.  The amendments in this ASU are effective for the first interim or annual period beginning after December 15, 2014; however, the disclosure for transactions accounted for as secured borrowings is required to be presented for annual periods beginning after December 15, 2014, and interim periods beginning after March 15, 2015. Early adoption is not permitted.  The adoption of the new guidance did not have a material impact on the Company's consolidated financial statements.
	In August 2014, the FASB issued ASU No. 2014-14, "Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40): Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure."  The amendments in this ASU apply to creditors that hold government-guaranteed mortgage loans and are intended to eliminate the diversity in practice related to the classification of these guaranteed loans upon foreclosure.  The new guidance stipulates that a mortgage loan be derecognized and a separate other receivable be recognized upon foreclosure if (1) the loan has a government guarantee that is not separable from the loan prior to foreclosure, (2) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim, and (3) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclosure, the other receivable should be measured on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2014. Entities may adopt the amendments on a prospective basis or modified retrospective basis as of the beginning of the annual period of adoption; however, the entity must apply the same method of transition as elected under ASU 2014-04. Early adoption is permitted provided the entity has already adopted ASU 2014-04.  The adoption of the new guidance did not have a material impact on the Company's consolidated financial statements.
	In August 2014, the FASB issued ASU No. 2014-15, "Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern."  This update is intended to provide guidance about management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures.  Management is required under the new guidance to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date the financial statements are issued when preparing financial statements for each interim and annual reporting period.  If conditions or events are identified, the ASU specifies the process that must be followed by management and also clarifies the timing and content of going concern footnote disclosures in order to reduce diversity in practice.  The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2016. Early adoption is permitted.  The Company does not expect the adoption of ASU 2014-15 to have a material impact on its consolidated financial statements.
	In November 2014, the FASB issued ASU No. 2014-16, "Derivatives and Hedging (Topic 815):  Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share Is More Akin to Debt or to Equity."  The amendments in this ASU do not change the current criteria in GAAP for determining when separation of certain embedded derivative features in a hybrid financial instrument is required. The amendments clarify how current GAAP should be interpreted in evaluating the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share. Specifically, the amendments clarify that an entity should consider all relevant terms and features, including the embedded derivative feature being evaluated for bifurcation, in evaluating the nature of the host contract. Furthermore, the amendments clarify that no single term or feature would necessarily determine the economic characteristics and risks of the host contract. Rather, the nature of the host contract depends upon the economic characteristics and risks of the entire hybrid financial instrument.  The amendments in this ASU also clarify that, in evaluating the nature of a host contract, an entity should assess the substance of the relevant terms and features (i.e., the relative strength of the debt-like or equity-like terms and features given the facts and circumstances) when considering how to weight those terms and features.  The amendments in this ASU are effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption, including adoption in an interim period, is permitted. The Company does not expect the adoption of ASU 2014-16 to have a material impact on its consolidated financial statements.
	In January 2015, the FASB issued ASU No. 2015-01, "Income Statement—Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items."  The amendments in this ASU eliminate from GAAP the concept of extraordinary items. Subtopic 225-20, Income Statement - Extraordinary and Unusual Items, 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 evidence clearly supports its classification as an extraordinary item.  If an event or transaction meets the criteria for extraordinary classification, an entity is required to segregate the extraordinary item from the results of ordinary operations and show the item separately in the income statement, net of tax, after income from continuing operations. The entity also is required to disclose applicable income taxes and either present or disclose earnings per share data applicable to the extraordinary item.  The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015.  Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption.  The Company does not expect the adoption of ASU 2015-01 to have a material impact on its consolidated financial statements.
	In February 2015, the FASB issued ASU No. 2015-02, "Consolidation (Topic 810): Amendments to the Consolidation Analysis."  The amendments in this ASU are intended to improve targeted areas of consolidation guidance for legal entities such as limited partnerships, limited liability corporations, and securitization structures (collateralized debt obligations, collateralized loan obligations, and mortgage-backed security transactions).  In addition to reducing the number of consolidation models from four to two, the new standard simplifies the FASB ASC and improves current GAAP by placing more emphasis on risk of loss when determining a controlling financial interest, reducing the frequency of the application of related-party guidance when determining a controlling financial interest in a variable interest entity ("VIE"), and changing consolidation conclusions for public and private companies in several industries that typically make use of limited partnerships or VIEs.  The amendments in this ASU are effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015.  Early adoption is permitted, including adoption in an interim period. ASU 2015-02 may be applied retrospectively in previously issued financial statements for one or more years with a cumulative-effect adjustment to retained earnings as of the beginning of the first year restated.  The Company does not expect the adoption of ASU 2015-02 to have a material impact on its consolidated financial statements.
	In April 2015, the FASB issued ASU No. 2015-03, "Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs."  The amendments in this ASU are intended to simplify the presentation of debt issuance costs.  These amendments require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this ASU.  The amendments in this ASU are effective for public business entities for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted for financial statements that have not been previously issued.  The Company does not expect the adoption of ASU 2015-03 to have a material impact on its consolidated financial statements.
	In April 2015, the FASB issued ASU No. 2015-05, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Fees Paid in a Cloud Computing Arrangement."  The amendments in this ASU provide guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The amendments do not change the accounting for a customer's accounting for service contracts. As a result of the amendments, all software licenses within the scope of Subtopic 350-40 will be accounted for consistent with other licenses of intangible assets.  The amendments in this ASU are effective for public business entities for annual periods, including interim periods within those annual periods, beginning after December 15, 2015.  Early adoption is permitted. An entity can elect to adopt the amendments either: (1) prospectively to all arrangements entered into or materially modified after the effective date, or (2) retrospectively.  The Company is currently assessing the impact that ASU 2015-05 will have on its consolidated financial statements.

	In many cases, the fair values of assets acquired and liabilities assumed were determined by estimating the cash flows expected to result from those assets and liabilities and discounting them at appropriate market rates. The most significant category of assets for which this procedure was used was that of acquired loans. The Company acquired the $122,300,000 loan portfolio at a fair value discount of $7,400,000. The estimated fair value of the performing portion of the portfolio was $105,800,000. The excess of expected cash flows above the fair value of the performing portion of loans will be accreted to interest income over the remaining lives of the loans in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 310-20.

Cost of restricted stock	Due to restrictions placed upon the Bank's common stock investment in the Federal Reserve Bank of Richmond ("FRB") and Federal Home Loan Bank of Atlanta ("FHLB"), these securities have been classified as restricted equity securities and carried at cost.  The restricted securities are not subject to the investment security classification and are included as a separate line item on the Company's balance sheet.  The FRB requires the Bank to maintain stock with a par value equal to 6.0% of its common stock and paid-in surplus.  One-half of this amount is paid to the FRB and the remaining half is subject to call when deemed necessary by the Board of Governors of the Federal Reserve System.  The FHLB requires the Bank to maintain stock in an amount equal to a specific percentage of the Bank's total assets and 4.5% of outstanding borrowings. The Bank also owns common stock in CBB Financial Corporation and Pacific Coast Bankers Bankshares, which both provide services to community banks. The cost of restricted stock at March 31, 2015 and December 31, 2014 were as follows (dollars in thousands):
