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, pension obligations, the valuation of foreclosed real estate, goodwill and intangible assets, the valuation of deferred tax assets, other-than-temporary impairments of securities, acquired loans with specific credit-related deterioration, and the fair value of financial instruments.
	In April 2006, AMNB Statutory Trust I, a Delaware statutory trust (the "AMNB Trust") and a wholly owned subsidiary of the Company, was formed for the purpose of issuing preferred securities (the "Trust Preferred Securities") in a private placement pursuant to an applicable exemption from registration.  Proceeds from the securities were used to fund the acquisition of Community First Financial Corporation ("Community First") which occurred in April 2006.
	On July 1, 2011, the Company completed its merger with MidCarolina Financial Corporation ("MidCarolina").  MidCarolina was headquartered in Burlington, North Carolina, and engaged in banking operations through its subsidiary bank, MidCarolina Bank.
	In July 2011, and in connection with its acquisition of MidCarolina, the Company assumed the liabilities of the MidCarolina I and MidCarolina Trust II, two separate Delaware statutory trusts (the "MidCarolina Trusts"), which were also formed for the purpose of issuing preferred securities.  Refer to Note 9 for further details concerning these entities.
	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 Company's financial position as of September 30, 2013; the consolidated statements of income for the three and nine months ended September 30, 2013 and 2012; the consolidated statements of comprehensive income (loss) for the three and nine months ended September 30, 2013 and 2012; the consolidated statements of changes in shareholders' equity for the nine months ended September 30, 2013 and 2012; and the consolidated statements of cash flows for the nine months ended September 30, 2013 and 2012.  Operating results for the three and nine month periods ended September 30, 2013 are not necessarily indicative of the results that may occur for the year ending December 31, 2013.  Certain reclassifications have been made to prior period balances to conform to the current period presentation. These statements should be read in conjunction with the Notes to Consolidated Financial Statements included in the Company's Form 10-K for the year ended December 31, 2012.

Merger with MidCarolina [Abstract]	'
Merger with MidCarolina	'
	Note 2 – Merger with MidCarolina
	On July 1, 2011, the Company completed its merger with MidCarolina Financial Corporation pursuant to the Agreement and Plan of Reorganization, dated December 15, 2010, between the Company and MidCarolina (the "merger agreement").  MidCarolina was headquartered in Burlington, North Carolina, and engaged in banking operations through its subsidiary bank, MidCarolina Bank.  The transaction has significantly expanded the Company's footprint in North Carolina, adding eight branches in Alamance and Guilford Counties.
	Pursuant to the terms of the merger agreement, as a result of the merger, the holders of shares of MidCarolina common stock received 0.33 shares of the Company's common stock for each share of MidCarolina common stock held immediately prior to the effective date of the merger. Each option to purchase a share of MidCarolina common stock outstanding immediately prior to the effective date of the merger was converted into an option to purchase shares of Company common stock, adjusted for the 0.33 exchange ratio. Additionally, the holders of shares of noncumulative perpetual Series A preferred stock of MidCarolina received one share of a newly authorized noncumulative perpetual Series A preferred stock of the Company for each MidCarolina preferred share held immediately before the merger.  The Company's Series A preferred stock was issued with terms, preferences, rights and limitations that are identical in all material respects to the MidCarolina Series A preferred stock. On November 15, 2011, the Company repurchased all Series A preferred stock at 62 percent of par.
	The Company issued 1,626,157 shares of common stock in connection with the MidCarolina merger. MidCarolina Bank was merged with and into the Bank on July 1, 2011.
	The merger with MidCarolina was accounted for using the acquisition method of accounting and, accordingly, assets acquired, liabilities assumed and consideration paid were recorded at their estimated fair values as of the merger date. The excess of consideration paid over the fair value of net assets acquired was originally recorded as goodwill in the amount of approximately $16.6 million, which will not be amortizable and is not deductible for tax purposes.  The Company allocated the total balance of goodwill to its community banking segment. The Company also recorded $6.6 million in core deposit intangibles which will be amortized over nine years using a declining balance method.
	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 (1,626,157)	$	29,905
	Cash paid to shareholders		12
	Fair value of options		132
	Preferred shares issued (5,000)		5,000
	Value of consideration		35,049
	Assets acquired:
	Cash and cash equivalents		34,783
	Investment securities		51,442
	Loans held for sale		113
	Loans, net of unearned income		328,123
	Premises and equipment, net		5,708
	Deferred income taxes		15,310
	Core deposit intangible		6,556
	Other real estate owned		3,538
	Other assets		13,535
	Total assets		459,108
	Liabilities assumed:
	Deposits		420,248
	FHLB advances		9,858
	Other borrowings		6,546
	Other liabilities		3,982
	Total liabilities		440,634
	Net assets acquired		18,474
	Goodwill resulting from merger with MidCarolina	$	16,575
	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 $367.4 million loan portfolio at a fair value discount of $39.9 million. The estimated fair value of the performing portion of the portfolio was $286.5 million. 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 (formerly SFAS 91).
	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 (formerly Statement of Position ("SOP") 03-3) as of July 1, 2011 (in thousands).
	Contractually required principal and interest at acquisition	$	56,681
	Contractual cash flows not expected to be collected (nonaccretable difference)		17,472
	Expected cash flows at acquisition		39,209
	Interest component of expected cash flows (accretable discount)		1,663
	Fair value of acquired loans accounted for under FASB ASC 310-30	$	37,546
	In accordance with GAAP, there was no carryover of the allowance for loan losses that had been previously recorded by MidCarolina.
	In connection with the merger with MidCarolina, the Company acquired an investment portfolio with a fair value of $51.4 million. 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 MidCarolina, the Company recorded a deferred income tax asset of $15.3 million related to MidCarolina's valuation allowance on foreclosed real estate and bad debt expenses, as well as other tax attributes of the acquired company, along with the effects of fair value adjustments resulting from applying the acquisition method of accounting.
	In connection with the merger with MidCarolina, the Company acquired other real estate owned with a fair value of $3.5 million. Other real estate owned was measured at fair value less estimated cost to sell.
	In connection with the merger with MidCarolina, the Company acquired premises and equipment with a fair value of $5.7 million. Property appraisals for all owned locations were obtained. The fair value adjustment will be amortized as expense over the remaining lives of the properties. The Company also acquired several lease obligations in connection with the merger. The unfavorable lease position will be amortized over the remaining lives of the leases.
	The fair value of savings and transaction deposit accounts acquired from MidCarolina 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 brokered, and Certificate of Deposit Account Registry Service®  (often referred to as "CDARS"). 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 will be accreted to reduce interest expense over the remaining maturities of the respective pools.
	The fair value of the Federal Home Loan Bank of Atlanta ("FHLB") advances was determined based on the discounted cash flows of future payments. This adjustment to the face value of the borrowings will be amortized to increase interest expense over the remaining lives of the respective borrowings.
	The fair value of junior subordinated debentures (Other Borrowings) was determined based on the fair value of similar debt or equity instruments with reasonably comparable terms. This adjustment to the face value of the borrowings will be amortized to increase interest expense over the remaining lives of the respective borrowings.
	Direct costs related to the acquisition were expensed as incurred. During the entire year of 2011, the Company incurred $1,600,000 in merger and acquisition expenses. During 2012, the Company incurred $251,000 in merger related expense. There were no merger related expenses in the three or nine months ended September 30, 2013.

	The following table shows estimated 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 September 30, 2013.  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.
	Available for sale securities that have been in a continuous unrealized loss position are as follows:

	GSE debt securities: The unrealized losses on the Company's investment in 14 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 bases 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 bases, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at September 30, 2013.
	Mortgage-backed securities and CMOs: The unrealized losses on the Company's investment in 17 GSE mortgage-backed securities and 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 September 30, 2013.
	State and municipal securities:  The unrealized losses on 33 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 September 30, 2013.
	Corporate securities:  The unrealized losses on nine 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 September 30, 2013.
	The Company's investment in FHLB stock totaled $2,000,000 at September 30, 2013.  FHLB stock is generally viewed as a long-term investment and as a restricted investment security, which is carried at cost, because there is no market for the stock, other than the FHLB or member institutions.  Therefore, when evaluating FHLB stock for impairment, its value is based on the ultimate recoverability of the par value rather than by recognizing temporary declines in value.  The Company does not consider this investment to be other-than-temporarily impaired at September 30, 2013 and no impairment has been recognized.  FHLB stock is shown in restricted stock on the balance sheet and is not a part of the available for sale securities portfolio.
	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, 2012.

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 distinct 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 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.

	The allowance for loan losses is allocated to loan segments based upon historical loss factors, risk grades on individual loans, portfolio analyses of smaller balance, homogenous loans, and qualitative factors.  Qualitative factors include trends in delinquencies, nonaccrual loans, and loss rates; trends in volume and terms of loans, effects of changes in risk selection, underwriting standards, and lending policies; experience of lending officers and other lending staff; national, regional, and local economic trends and conditions; legal, regulatory and collateral factors; and concentrations of credit.  A large percentage of the Bank's North Carolina loan portfolio is commercial real estate, with relatively short maturities, with balloon payments, and relatively long amortization periods. This structure results in more rapid accretion of the acquisition related credit mark than amortization of loan principal. While this is not a proximate cause in and of itself for additional provision, it does result in an increased volume of loans that must be evaluated for potential loss as they are renewed on current market terms and conditions and become part of the regular portfolio.  Since the MidCarolina merger, approximately $88 million of the acquired loan portfolio has renewed under such terms and is considered as part of the regular loan loss allowance analysis.

Goodwill_and_Other_Intangible_

Goodwill and Other Intangible Assets	9 Months Ended

Goodwill and Other Intangible Assets [Abstract]	'
Goodwill and Other Intangible Assets	'
	Note 6 – Goodwill and Other Intangible Assets
	Goodwill is subject to at least an annual assessment for impairment by applying a fair value test.  An annual fair value-based test was performed as of June 30, 2013 that determined the market value of the Company's shares exceeded the consolidated carrying value, including goodwill; therefore, there has been no impairment recognized in the value of goodwill.
	In September 2011, the FASB published Accounting Statement Update ("ASU") 2011-08, "Testing Goodwill for Impairment." This amendment was an effort to reduce the complexity of the two step impairment test required by the original version of the ASU. Under this amendment, the reporting entity has the option to assess relevant "qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of the reporting entity is less than the carrying amount."
	Core deposit intangibles resulting from the Community First acquisition in April 2006 were $3,112,000 and are being amortized over 99 months.  Core deposit intangibles resulting from the MidCarolina acquisition in July 2011 were $6,556,000 and are being amortized on an accelerated basis over 108 months.

Note 9 – Trust Preferred Capital Notes

On April 7, 2006, the AMNB Trust, a Delaware statutory trust and a wholly owned subsidiary of the Company, issued $20,000,000 of 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 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 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 Statutory 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.

	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, which plan 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 nine months ended September 30, 2013 is as follows:
		Option		Weighted		Weighted	Aggregate
		Shares		Average		Average	Intrinsic

	Exercisable at September 30, 2013		207,247	$	24.65	3.09 years		$	267
	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 September 30, 2013, 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 nine months ended September 30, 2013 is summarized in the following table.
	Restricted Stock	Shares		Weighted Average Grant Date Value
	Nonvested at January 1, 2013		39,327	$	20.17

	As of September 30, 2013 and December 31, 2012, there was $383,000 and $525,000 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 1.20 years.   The share based compensation expense for nonvested restricted stock was $211,000 and $260,000 during the first nine months of 2013 and 2012, respectively.
	Starting in 2010, the Company began offering its outside directors alternatives with respect to director compensation. For 2012, the regular quarterly board retainer could be received in the form of either (i) $3,000 in cash or (ii) shares of immediately vested, but restricted stock with a market value of $4,688. Monthly meeting fees can also be received as $600 per meeting in cash or $750 in immediately vested, but restricted stock.  For 2013, all 11 outside directors have elected to receive stock in lieu of cash for their monthly retainer board meeting fees. Only outside directors receive board fees. The Company issued 9,968 and 14,217 shares and recognized share based compensation expense of $213,000 and $308,000 during the first nine months of 2013 and 2012, respectively.

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, the fair value of a financial 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 financial 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 financial assets and financial 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 financial 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). Federal Reserve Bank of Richmond 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 table below.

	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 nine month period ended September 30, 2013 or the year ended December 31, 2012. 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.  The measurement of loss associated with impaired loans can be based on either the observable market price of the loan or the fair value of the collateral.  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 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 September 30, 2013 and December 31, 2012, 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.

	Note 17 – Recent Accounting Pronouncements
	In December 2011, the FASB issued ASU 2011-11, "Balance Sheet (Topic 210) – Disclosures about Offsetting Assets and Liabilities."  This ASU requires entities to disclose both gross information and net information about both instruments and transactions eligible for offset in the balance sheet and instruments and transactions subject to an agreement similar to a master netting arrangement. An entity is required to apply the amendments for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. An entity should provide the disclosures required by those amendments retrospectively for all comparative periods presented. The adoption of the new guidance did not have a material impact on Company's consolidated financial statements.
	In July 2012, the FASB issued ASU 2012-02, "Intangibles – Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment."  The amendments in this ASU apply to all entities that have indefinite-lived intangible assets, other than goodwill, reported in their financial statements.  The amendments in this ASU provide an entity with the option to make a qualitative assessment about the likelihood that an indefinite-lived intangible asset is impaired to determine whether it should perform a quantitative impairment test. The amendments also enhance the consistency of impairment testing guidance among long-lived asset categories by permitting an entity to assess qualitative factors to determine whether it is necessary to calculate the asset's fair value when testing an indefinite-lived intangible asset for impairment.  The amendments are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. 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 2013, the FASB issued ASU 2013-01, "Balance Sheet (Topic 210): Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities."  The amendments in this ASU clarify the scope for derivatives accounted for in accordance with Topic 815, Derivatives and Hedging, including bifurcated embedded derivatives, repurchase agreements and reverse repurchase agreements and securities borrowing and securities lending transactions that are either offset or subject to netting arrangements.  An entity is required to apply the amendments for fiscal years, and interim periods within those years, beginning on or after January 1, 2013.  The adoption of the new guidance did not have a material impact on the Company's consolidated financial statements.
	In February 2013, the FASB issued ASU 2013-02, "Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income."  The amendments in this ASU require an entity to present (either on the face of the statement where net income is presented or in the notes) the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income.  In addition, the amendments require a cross-reference to other disclosures currently required for other reclassification items to be reclassified directly to net income in their entirety in the same reporting period.  Companies should apply these amendments for fiscal years, and interim periods within those years, beginning on or after December 15, 2012.  The Company has included the required disclosures from ASU 2013-02 in the consolidated financial statements.
	In July 2013, the FASB issued ASU 2013-10, "Derivatives and Hedging (Topic 815):  Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes."  The amendments in this ASU permit the Fed Funds Effective Swap Rate (also referred to as the Overnight Index Swap Rate) to be used as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815, in addition to interest rates on direct Treasury obligations of the U.S. government and the London Interbank Offered Rate.  The amendments also remove the restriction on using different benchmark rates for similar hedges.  The amendments apply to all entities that elect to apply hedge accounting of the benchmark interest rate under Topic 815.  The amendments are effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013.  The adoption of the new guidance did not have a material impact on the Company's consolidated financial statements.
	In July 2013, the FASB issued ASU 2013-11, "Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists."   The amendments in this Update provide guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, similar tax loss, or tax credit carryforward exists.  An unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets.  The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013.  Early adoption is permitted. The amendments should be applied prospectively to all unrecognized tax benefits that exist at the effective date. Retrospective application is permitted.  The adoption of the new guidance did not have a material impact on the Company's consolidated financial statements.
