Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1 – Summary of Significant Accounting Policies
	Nature of Operations and Consolidation
	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, goodwill and intangible assets, other than temporary impairment, the valuation of deferred tax assets and liabilities, and the valuation of foreclosed real estate.
	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") pursuant to the terms and conditions of the Agreement and Plan of Reorganization, dated December 15, 2010, between the Company and MidCarolina.  MidCarolina was headquartered in Burlington, North Carolina, and engaged in banking operations through its subsidiary bank, MidCarolina Bank.  The transaction has expanded the Company's footprint in North Carolina, adding eight branches in Alamance and Guilford Counties.
	In July 2011, and in connection with its acquisition of MidCarolina Financial Corporation, the Company assumed the liabilities of the MidCarolina Trust I and MidCarolina Trust II, two separate Delaware statutory trust (the "MidCarolina Trusts"), which were also formed for the purpose of issuing preferred securities.  Refer to Note 12 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 12.
	Cash and Cash Equivalents
	Cash includes cash on hand, cash with correspondent banks, and cash on deposit at the Federal Reserve Bank of Richmond.  Cash equivalents are short-term, highly liquid investments that are readily convertible to cash with original maturities of three months or less and are subject to an insignificant risk of change in value.  Cash and cash equivalents are carried at cost.
	Interest-bearing Deposits in Other Banks
	Interest-bearing deposits in other banks mature within one year and are carried at cost.
	Securities
	Certain debt securities that management has the positive intent and ability to hold to maturity are classified as "held to maturity" and recorded at amortized cost. Trading securities are recorded at fair value with changes in fair value included in earnings. Securities not classified as held to maturity or trading, including equity securities with readily determinable fair values, are classified as "available for sale" and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method.
	The Company does not currently have any securities in held to maturity or trading and has no plans to add any to either category.
	The Company follows accounting guidance related to recognition and presentation of other-than-temporary impairment. The guidance specifies that (1) if a company does not have the intent to sell a debt security prior to recovery and (2) it is more likely than not that it will not have to sell the debt security prior to recovery, the security would not be considered other-than-temporarily impaired, unless there is a credit loss. When an entity does not intend to sell the security and it is more likely than not the entity will not have to sell the security before recovery of its cost basis, it will recognize the credit component of an other-than-temporary impairment of a debt security in earnings and the remaining portion in other comprehensive income. For held-to-maturity debt securities, the amount of an other-than-temporary impairment recorded in other comprehensive income for the noncredit portion of a previous other-than-temporary impairment should be amortized prospectively over the remaining life of the security on the basis of the timing of future estimated cash flows of the security.
	For equity securities, when the Company has decided to sell an impaired available-for-sale security and the entity does not expect the fair value of the security to fully recover before the expected time of sale, the security is deemed other-than-temporarily impaired in the period in which the decision to sell is made. The Company recognizes an impairment loss when the impairment is deemed other-than-temporary even if a decision to sell has not been made.
	Due to the nature and restrictions placed on the Company's investment in common stock of the Federal Home Loan Bank of Atlanta ("FHLB") and the Federal Reserve Bank of Richmond, these securities have been classified as restricted equity securities and carried at cost.
	Loans Held for Sale
	Secondary market mortgage loans are designated as held for sale at the time of their origination.  These loans are pre-sold with servicing released and the Company does not retain any interest after the loans are sold.  These loans consist primarily of fixed-rate, single-family residential mortgage loans which meet the underwriting characteristics of certain government-sponsored enterprises (conforming loans).  In addition, the Company requires a firm purchase commitment from a permanent investor before a loan can be committed, thus limiting interest rate risk.  Loans held for sale are carried at fair value.  Gains on sales of loans are recognized at the loan closing date and are included in noninterest income.
	Derivative Loan Commitments
	The Company enters into mortgage loan commitments whereby the interest rate on the loan is determined prior to funding (rate lock commitments).  Mortgage loan commitments are referred to as derivative loan commitments if the loan that will result from exercise of the commitment will be held for sale upon funding.  Loan commitments that are derivatives are recognized at fair value on the consolidated balance sheets with net changes in their fair values recorded in other expenses.  Derivative loan commitments resulted in no income or loss for 2014, 2013 or 2012.
	The period of time between issuance of a loan commitment and sale of the loan generally ranges from 30 to 60 days. The Company protects itself from changes in interest rates through the use of best efforts forward delivery contracts, by committing to sell a loan at the time the borrower commits to an interest rate with the intent that the buyer has assumed the interest rate risk on the loan.  As a result, the Company is not generally exposed to significant losses nor will it realize significant gains related to its rate lock commitments due to changes in interest rates.  The correlation between the rate lock commitments and the best efforts contracts is very high due to their similarity.
	The market value of rate lock commitments and best efforts contracts is not readily ascertainable with precision because rate lock commitments and best efforts contracts are not actively traded in stand-alone markets.  The Company determines the fair value of rate lock commitments and best efforts contracts by measuring the change in the estimated value of the underlying assets while taking into consideration the probability that the loan will be funded.
	Loans
	The Company makes mortgage, commercial, and consumer loans.  A substantial portion of the loan portfolio is secured by real estate.  The ability of the Company's debtors to honor their contracts is dependent upon the real estate market and general economic conditions in the Company's market area.
	Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off, generally are reported at their outstanding unpaid principal balance adjusted for the allowance for loan losses, and any deferred fees or costs.  Interest income is accrued on the unpaid principal balance.  Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method.
	The accrual of interest on loans is generally discontinued at the time the loan is 90 days delinquent unless the credit is well-secured and in process of collection.  Loans are typically charged off when the loan is 120 days past due, unless secured and in process of collection.  Loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful.
	Interest accrued but not collected for loans that are placed on nonaccrual status or charged-off is reversed against interest income.  The interest on these loans is accounted for on the cash basis or cost recovery method, until qualifying for return to accrual status.  Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
	A loan is considered past due when a payment of principal or interest or both is due but not paid.  Management closely monitors past due loans in timeframes of 30-59 days, 60-89 days, and 90 or more days past due.
	These policies apply to all loan portfolio classes and segments.
	Substandard and doubtful risk graded commercial, commercial real estate, and construction loans equal to or greater than $100,000 on an unsecured basis, and equal to or greater than $250,000 on a secured basis are reviewed for impairment. All troubled debt restructurings, regardless of dollar amount, are also evaluated for impairment. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement.  Factors considered by management in determining impairment and establishing a specific allowance include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due.  Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower's prior payment record, and the amount of the shortfall in relation to the principal and interest owed.  Impairment is measured on a loan-by-loan basis for commercial, commercial real estate, and construction loans by either the present value of expected future cash flows discounted at the loan's effective interest rate, the loan's obtainable market price, or the fair value of the collateral if the loan is collateral dependent.
	Generally, large groups of smaller balance homogeneous loans (residential real estate and consumer loans) are collectively evaluated for impairment.  The Company's policy for recognizing interest income on impaired loans is consistent with its nonaccrual policy.
	The Company's loan portfolio is organized by major segment. These include:  commercial, commercial real estate, residential real estate and consumer loans.  Each segment has particular risk characteristics that are specific to the borrower and the generic category of credit.  Commercial loan repayments are highly dependent on cash flows associated with the underlying business and its profitability.  They can also be impacted by changes in collateral values.  Commercial real estate loans share the same general risk characteristics as commercial loans, but are often more dependent on the value of the underlying real estate collateral and, when construction is involved, the ultimate completion of and sale of the project.  Residential real estate loans are generally dependent on the value of collateral and the credit worthiness of the underlying borrower.  Consumer loans are very similar in risk characteristics to residential real estate.
	In connection with the MidCarolina merger, certain loans were acquired which exhibited deteriorated credit quality since origination and for which the Bank does not expect to collect all contractual payments.  These purchased credit impaired loans are recorded at the amount paid, such that there is no carryover of the seller's allowance for loan losses.  After acquisition, losses are recognized by an increase in the allowance for loan losses.
	Such purchased credit impaired loans are accounted for individually or aggregated into pools of loans based on common risk characteristics such as, credit score, loan type, and date of origination.  The Company estimates the amount and timing of expected cash flows for each loan or pool, and the expected cash flows in excess of amount paid is recorded as interest income over the remaining life of the loan or pool (accretable yield).  The excess of the loan's or pool's contractual principal and interest over expected cash flows is not recorded (nonaccretable difference).
	Over the life of the loan or pool, expected cash flows continue to be estimated.  It the present value of expected cash flows is less than the carrying amount, a loss is recorded as a provision for loan losses.  If the present value of expected cash flows is greater than the carrying amount, it is recognized as part of future interest income.

	In situations where, for economic or legal reasons related to a borrower's financial condition, management may grant a concession to the borrower that it would not otherwise consider, the related loan is classified as a troubled debt restructuring ("TDR").  Management strives to identify borrowers in financial difficulty early and work with them to modify their loan to more affordable terms before their loan reaches nonaccrual status.  These modified terms may include rate reductions, principal forgiveness, payment forbearance and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of the collateral.  In cases where borrowers are granted new terms that provide for a reduction of either interest or principal, management measures any impairment on the restructuring as noted above for impaired loans.  The Company has $2,862,000 in loans classified as TDRs as of December 31, 2014 and $2,100,000 as of December 31, 2013.
	Allowance for Loan Losses
	The purpose of the allowance for loan losses ("ALLL") is to provide for probable losses inherent in the loan portfolio.  The allowance is increased by the provision for loan losses and by recoveries of previously charged-off loans.  Loan charge-offs decrease the allowance.
	The goal of the Company is to maintain an appropriate, systematic, and consistently applied process to determine the amounts of the ALLL and the provision for loan loss expense.
	The Company uses certain practices to manage its credit risk.  These practices include (1) appropriate lending limits for loan officers, (2) a loan approval process, (3) careful underwriting of loan requests, including analysis of borrowers, cash flows, collateral, and market risks, (4) regular monitoring of the portfolio, including diversification by type and geography, (5) review of loans by the Loan Review department, which operates independently of loan production, (6) regular meetings of the Credit Committees to discuss portfolio and policy changes and make decisions on large or unusual loan requests, and (7) regular meetings of the Asset Quality Committee which reviews the status of individual loans.
	Risk grades are assigned as part of the loan origination process. From time to time risk grades may be modified as warranted by the facts and circumstances surrounding the credit.
	Calculation and analysis of the allowance for loan losses is prepared quarterly by the Finance Department.  The Company's Credit Committee, Capital Management Committee, Audit Committee, and the Board of Directors review the allowance for adequacy.
	The Company's allowance for loan losses has two basic components:  the formula allowance and the specific allowance.  Each of these components is determined based upon estimates and judgments.
	The formula allowance uses historical loss experience as an indicator of future losses, along with various qualitative factors, including levels and trends in delinquencies, nonaccrual loans, charge-offs and recoveries, trends in volume and terms of loans, effects of changes in underwriting standards, experience of lending staff, economic conditions, and portfolio concentrations. In the formula allowance for commercial and commercial real estate loans, the historical loss rate is combined with the qualitative factors, resulting in an adjusted loss factor for each risk-grade category of loans.  The period-end balances for each loan risk-grade category are multiplied by the adjusted loss factor.  Allowance calculations for consumer loans are calculated based on historical losses for each product category without regard to risk grade. This loss rate is combined with qualitative factors resulting in an adjusted loss factor for each product category.
	The specific allowance uses various techniques to arrive at an estimate of loss for specifically identified impaired loans. These include:
	·	The present value of expected future cash flows discounted at the loan's effective interest rate.  The effective interest rate on a loan is the rate of return implicit in the loan (that is, the contractual interest rate adjusted for any net deferred loan fees or costs and any premium or discount existing at the origination or acquisition of the loan);
	·	The loan's observable market price, or
	·	The fair value of the collateral, net of estimated costs to dispose, if the loan is collateral dependent.
	The use of these computed values is inherently subjective and actual losses could be greater or less than the estimates.
	No single statistic, formula, or measurement determines the adequacy of the allowance.  Management makes subjective and complex judgments about matters that are inherently uncertain, and different amounts would be reported under different conditions or using different assumptions.  For analytical purposes, management allocates a portion of the allowance to specific loan categories and specific loans.  However, the entire allowance is used to absorb credit losses inherent in the loan portfolio, including identified and unidentified losses.
	The relationships and ratios used in calculating the allowance, including the qualitative factors, may change from period to period as facts and circumstances evolve.  Furthermore, management cannot provide assurance that in any particular period the Company will not have sizeable credit losses in relation to the amount reserved.  Management may find it necessary to significantly adjust the allowance, considering current factors at the time.
	Premises and Equipment
	Land is carried at cost.  Premises and equipment are stated at cost, less accumulated depreciation and amortization.  Premises and equipment are depreciated over their estimated useful lives ranging from three years to thirty-nine years; leasehold improvements are amortized over the lives of the respective leases or the estimated useful lives of the improvements, whichever is less.  Software is generally amortized over three years.  Depreciation and amortization are recorded on the straight-line method.
	Costs of maintenance and repairs are charged to expense as incurred.  Costs of replacing structural parts of major units are considered individually and are expensed or capitalized as the facts dictate.  Gains and losses on routine dispositions are reflected in current operations.
	Goodwill and Intangible Assets
	Goodwill is subject to at least an annual assessment for impairment by applying a fair value based test.  Additionally, acquired intangible assets (such as core deposit intangibles) are separately recognized if the benefit of the assets can be sold, transferred, licensed, rented, or exchanged, and amortized over their useful lives.  Intangible assets related to branch transactions continued to amortize. The cost of purchased deposit relationships and other intangible assets, based on independent valuation, are being amortized over their estimated lives ranging from eight to ten years.
	The Company records as goodwill the excess of 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 during the years ended December 31, 2014, 2013, and 2012.
	Trust Assets
	Securities and other property held by the trust and investment services segment in a fiduciary or agency capacity are not assets of the Company and are not included in the accompanying consolidated financial statements.
	Other Real Estate Owned
	Other real estate owned represents real estate that has been acquired through loan foreclosures or deeds received in lieu of loan payments. Generally, such properties are appraised at the time acquired, and are recorded at the fair value less estimated selling costs.  Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in noninterest expense.
Transfers of Financial Assets
Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered.  Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company – put presumptively beyond reach of the transferor and its creditors, even in bankruptcy or other receivership, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets.
Income Taxes
The Company uses the balance sheet method to account for deferred income tax assets and liabilities.  Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws.
When tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained.  The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any.  Tax positions taken are not offset or aggregated with other positions.  Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority.  The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits in the accompanying consolidated balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination.  The Company had no liability for unrecognized tax benefits as of December 31, 2014 and 2013.
Stock-Based Compensation
Stock compensation accounting guidance ASC 718, "Compensation – Stock Compensation" requires that the compensation cost relating to share-based payment transactions be recognized in financial statements.  That cost will be measured based on the grant date fair value of the equity or liability instruments issued.  The stock compensation accounting guidance covers a wide range of share-based compensation arrangements including stock options, restricted share plans, performance-based awards, share appreciation rights, and employee share purchase plans.
The stock compensation accounting guidance requires that compensation cost for all stock awards be calculated and recognized over the employees' service period, generally defined as the vesting period.  For awards with graded-vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award.  A Black-Scholes model is used to estimate the fair value of stock options, while the market price of the Company's common stock at the date of grant is used for restricted stock awards.
Earnings Per Common Share
Basic earnings per common share represent income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per common share reflect the impact of additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Company consist solely of outstanding stock options, and are determined using the treasury method. Nonvested shares of restricted stock are included in the computation of basic earning per share because the holder has voting rights and shares in non-forfeitable dividends during the vesting period.
Comprehensive Income
Comprehensive income is shown in a two statement approach, the first statement presents total net income and its components followed by a second statement that presents all the components of other comprehensive income such as unrealized gains and losses on available for sale securities and changes in the funded status of a defined benefit postretirement plan.
Advertising and Marketing Costs
Advertising and marketing costs are expensed as incurred, and were $453,000, $607,000, and $454,000 in 2014, 2013, and 2012, respectively.
Mergers and Acquisitions
Business combinations are accounted for under ASC 805, "Business Combinations", using the acquisition method of accounting. The acquisition method of accounting requires an acquirer to recognize the assets acquired and the liabilities assumed at the acquisition date measured at their fair values as of that date. To determine the fair values, the Company relies on third party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other valuation techniques. Under the acquisition method of accounting, the Company identifies the acquirer and the closing date and applies applicable recognition principles and conditions.
Acquisition-related costs are costs the Company incurs to effect a business combination. Those costs include advisory, legal, accounting, valuation, and other professional or consulting fees. Some other examples of costs to the Company include systems conversions, integration planning consultants and advertising costs. The Company accounts for acquisition-related costs as expenses in the periods in which the costs are incurred and the services are received, with one exception. The costs to issue debt or equity securities is recognized in accordance with other applicable GAAP. These acquisition-related costs have been and will be included within the Consolidated Statements of Income classified within the noninterest expense caption.
Reclassifications
Certain reclassifications have been made in prior years financial statements to conform to classifications used in the current year. There were no material reclassifications.
Use of Estimates
In preparing consolidated financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and 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.
Recent Accounting Pronouncements
In January 2014, the FASB issued Accounting Standards Update ("ASU") 2014-01, "Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects (a consensus of the FASB Emerging Issues Task Force)."  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 Company is currently assessing the impact that ASU 2014-01 will have on its consolidated financial statements.
In January 2014, the FASB issued ASU 2014-04, "Receivables—Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure (a consensus of the FASB Emerging Issues Task Force)."  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 Company is currently assessing the impact that ASU 2014-04 will have on its consolidated financial statements.
In April 2014, the FASB issued ASU 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." The amendments in this ASU change the criteria for reporting discontinued operations while enhancing disclosures in this area. Under the new guidance, only disposals representing a strategic shift in operations should be presented as discontinued operations. Those strategic shifts should have a major effect on the organization's operations and financial results and include disposals of a major geographic area, a major line of business, or a major equity method investment. The new guidance requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. Additionally, the new guidance requires disclosure of the pre-tax income attributable to a disposal of a significant part of an organization that does not qualify for discontinued operations reporting. The amendments in the ASU are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. Early adoption is permitted.  The Company does not expect the adoption of ASU 2014-08 to have a material impact on its 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. 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 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 its 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 Company is currently assessing the impact that ASU 2014-11 will have on its consolidated financial statements.
In June 2014, the FASB issued ASU No. 2014-12, "Compensation – Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period." The new guidance applies to reporting entities that grant employees share-based payments in which the terms of the award allow a performance target to be achieved after the requisite service period. The amendments in the ASU require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition.  Existing guidance in "Compensation – Stock Compensation (Topic 718)," should be applied to account for these types of awards. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted and reporting entities may choose to apply the amendments in the ASU either on a prospective or retrospective basis.  The Company is currently assessing the impact that ASU 2014-12 will have on its 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 Company is currently assessing the impact that ASU 2014-14 will have on its 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 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 November 2014, the FASB issued ASU No. 2014-17, "Business Combinations (Topic 805):  Pushdown Accounting."  The amendments in ASU provide an acquired entity with an option to apply pushdown accounting in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity.  An acquired entity may elect the option to apply pushdown accounting in the reporting period in which the change-in-control event occurs. An acquired entity should determine whether to elect to apply pushdown accounting for each individual change-in-control event in which an acquirer obtains control of the acquired entity. If pushdown accounting is not applied in the reporting period in which the change-in-control event occurs, an acquired entity will have the option to elect to apply pushdown accounting in a subsequent reporting period to the acquired entity's most recent change-in-control event. An election to apply pushdown accounting in a reporting period after the reporting period in which the change-in-control event occurred should be considered a change in accounting principle in accordance with Topic 250, Accounting Changes and Error Corrections. If pushdown accounting is applied to an individual change-in-control event, that election is irrevocable.  The amendments in this ASU are effective on November 18, 2014. After the effective date, an acquired entity can make an election to apply the guidance to future change-in-control events or to its most recent change-in-control event. However, if the financial statements for the period in which the most recent change-in-control event occurred already have been issued or made available to be issued, the application of this guidance would be a change in accounting principle.  The Company does not expect the adoption of ASU 2014-17 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.

Merger with MainStreet [Abstract]
Merger with MainSteet	Note 2 - Acquisition of MainStreet BankShares, Inc.
	On January 1, 2015, the Company completed its acquisition of MainStreet. The merger of MainStreet with and into the Company was effected pursuant to the terms and conditions of the MainStreet Merger Agreement.  Immediately after the merger of MainStreet into the Company, Franklin Community Bank, N.A., MainStreet's wholly-owned bank subsidiary, merged with and into the Bank.
	Pursuant to the MainStreet Merger Agreement, the former 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 million from the Bank to the Company, and no borrowing was incurred by the Company or the Bank in connection with the merger.
	MainStreet was the holding company for Franklin Bank.  As of December 31, 2014, MainStreet had total net loans of approximately $122 million, total assets of approximately $164 million, and total deposits of approximately $137 million. Franklin Bank provided banking services to its customers from three banking offices located in Rocky Mount, Hardy, and Union Hall, Virginia, which are now branch offices of the Bank.

	The amortized cost and estimated fair value of investments in securities at December 31, 2014, by contractual maturity, are shown in the following table.  Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.  Because mortgage-backed securities have both known principal repayment terms as well as unknown principal repayments due to potential borrower pre-payments, it is difficult to accurately predict the final maturity of these investments.  Mortgage-backed securities are shown separately (dollars in thousands):

	Securities with a carrying value of approximately $168,965,000 and $154,946,000 at December 31, 2014 and 2013, respectively, were pledged to secure public deposits, repurchase agreements, and for other purposes as required by law.  FHLB letters of credit were used as additional collateral in the amounts of $70,000,000 at December 31, 2014 and $72,000,000 at December 31, 2013.
	Temporarily Impaired Securities
	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 December 31, 2014.  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 (dollars in thousands):
			Total								Less than 12 Months					12 Months or More
			Fair Value				Unrealized				Fair Value			Unrealized		Fair Value		Unrealized

	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 December 31, 2014.
	GSE residential mortgage-backed securities: The unrealized losses on the Company's investment in seven GSE mortgage-backed securities 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 bases 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 bases, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at December 31, 2014.
	State and municipal securities:  The unrealized losses on 25 state and municipal securities were caused by interest rate increases and not credit deterioration. 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 December 31, 2014.
	Corporate securities:  The unrealized losses on five corporate securities were caused by interest rate increases and not credit deterioration. 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 December 31, 2014.
	Due to restrictions placed upon the Bank's common stock investment in the Federal Reserve Bank and FHLB, these securities have been classified as restricted equity securities and carried at cost. These restricted securities are not subject to the investment security classifications and are included as a separate line item on the Company's Consolidated Balance Sheet. The FHLB requires the Bank to maintain stock in an amount equal to 4.5% of outstanding borrowings and a specific percentage of the Bank's total assets. The Federal Reserve Bank of Richmond requires the Bank to maintain stock with a par value equal to 6% of its outstanding capital. Restricted equity securities consist of Federal Reserve Bank stock in the amount of $2,742,000 and $2,722,000 as of December 31, 2014 and 2013 and FHLB stock in the amount of $1,625,000 and $2,000,000 as of December 31, 2014 and 2013, respectively.

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 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 8– Goodwill and Other Intangible Assets
	The Company records as goodwill the excess of 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 during the years ended December 31, 2014, 2013, and 2012.
	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.
	The changes in the carrying amount of goodwill and intangibles for the twelve months ended December 31, 2014, are as follows (dollars in thousands):

Note 10 – Short-term Borrowings

Short-term borrowings consist of customer repurchase agreements, overnight borrowings from the FHLB, and Federal Funds purchased.  The Company has federal funds lines of credit established with two correspondent banks in the amounts of $15,000,000 and $10,000,000, and, additionally, has access to the Federal Reserve Bank of Richmond's discount window.  Customer repurchase agreements are collateralized by securities of the U.S. Government, its agencies or Government Sponsored Entities ("GSEs").  They mature daily.  The interest rates are generally fixed but may be changed at the discretion of the Company. The securities underlying these agreements remain under the Company's control. FHLB overnight borrowings 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.  Short-term borrowings consisted solely of customer repurchase agreements at December 31, 2014 and 2013 (dollars in thousands):

Long-term Borrowings	Note 11 – 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 December 31, 2014, $418,087,000 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, advances as of December 31, 2014 and 2013 (dollars in thousands):

	The advance due in November 2017 is net of a fair value discount of $65,000. 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.
	In the regular course of conducting its business, the Company takes deposits from political subdivisions of the states of Virginia and North Carolina. At December 31, 2014, the Bank's public deposits totaled $128,116,000. 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 December 31, 2014, the Company had $70,000,000 in letters of credit with the FHLB outstanding as well as $109,532,622 in agency, state, and municipal securities to provide collateral for such deposits.

Trust Preferred Capital Notes	Note 12 – Trust Preferred Capital Notes
	On April 7, 2006, AMNB Statutory Trust I, 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 beginning on June 30, 2011.  Initially, the securities required quarterly distributions by the trust to the holder of the Trust Preferred Securities at a fixed rate of 6.66%.  Effective June 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 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 a 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 ASC 810-10-15-14, "Consolidation – Overall - Scope and Scope Exceptions," 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.
	A description of the junior subordinated debt securities outstanding payable to the trusts is shown below (dollars in thousands):
					Principal Amount
	Issuing Entity	Date Issued	Interest Rate	Maturity Date	31-Dec-14		31-Dec-13

					$	27,521	$	27,419
	The principal amounts reflected for the MidCarolina Trusts are net of valuation allowances of $1,001,000 and $861,000 respectively. The original valuation allowances of $1,197,000 and $1,021,000 were recorded as a result of the merger with MidCarolina on July 1, 2011 and are being amortized into interest expense over the remaining lives of the respective borrowings.

Stock-Based Compensation	Note 13 – 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, 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 year ended December 31, 2014 is as follows:
			Option				Weighted			Weighted	Aggregate

	Exercisable at December 31, 2014			110,947			$	26.08		2.80 years		$	171
	The aggregate intrinsic value of stock options in the table above represents the total pre-tax intrinsic value (the amount by which the current market value of the underlying stock exceeds the exercise price of the option) that would have been received by the option holders had all option holders exercised their options on December 31, 2014.  This amount changes based on changes in the market value of the Company's common stock.
	The total proceeds of the in-the-money options exercised during the year ended December 31, 2014, 2013, and 2012 were $442,000, $309,000, and $118,000, respectively.  Total intrinsic value of options exercised during years ended December 31, 2014, 2013, and 2012 was $178,000, $75,000, and $33,000, respectively.
	As of December 31, 2014, 2013, and 2012, there was no recognized or unrecognized compensation expense attributable to the outstanding stock options.

	No stock options were granted in 2014 and 2013.
	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 in 2014 cliff vests over 24 to 36 months based on the term of the award.
	Nonvested restricted stock activity for the year ended December 31, 2014 is summarized in the following table:
	Restricted Stock		Shares				Weighted
							Average Grant

	Starting in 2010, the Company began offering its outside directors alternatives with respect to director compensation. For 2014, the monthly board retainer could 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 2014, all 13 outside directors elected to receive stock in lieu of cash for their monthly retainer board meeting fees. Only outside directors receive board fees. The Company issued 13,147, 12,711, and 17,908 shares and recognized share based compensation expense of $298,000, $282,000, and $381,000 during 2014, 2013 and 2012, respectively.

	The Company is party to credit-related financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers.  These financial instruments include commitments to extend credit and standby letters of credit.  Such commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the Consolidated Balance Sheets.  The Company evaluates each customer's credit worthiness on a case-by-case basis.  The amount of collateral obtained, if applicable, is based on management's credit evaluation of the customer.
	The Company's exposure to credit loss is represented by the contractual amount of these commitments.  The Company follows the same credit policies in making commitments as it does for on-balance sheet instruments.
	The following off-balance sheet financial instruments whose contract amounts represent credit risk were outstanding at December 31, 2014 and 2013 (dollars in thousands):
		December 31,
		2014			2013
	Commitments to extend credit		$	190,413		$	179,272
	Standby letters of credit			3,333			3,405
	Mortgage loan rate lock commitments			3,372			5,913
	Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. These commitments generally consist of unused portions of lines of credit issued to customers. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee.  Since some of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.
	Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party.  Those letters of credit are primarily issued to support public and private borrowing arrangements.  The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers.
	At December 31, 2014, the Company had locked-rate commitments to originate mortgage loans amounting to approximately $3,372,000 and loans held for sale of $616,000. Risks arise from the possible inability of counterparties to meet the terms of their contracts, though the Company has never experienced a failure of one of its counterparties to perform.  If a loan becomes past due 90 days within 180 days of sale, the Company would be required to repurchase the loan.

Related Party Transactions [Abstract]
Related Party Transactions	Note 17 – Related Party Transactions
	In the ordinary course of business, loans are granted to executive officers, directors, and their related entities.  Management believes that all such loans are made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans to similar, unrelated borrowers, and do not involve more than a normal risk of collectibility or present other unfavorable features.  As of December 31, 2014 and 2013, none of these loans were restructured, past due, or on nonaccrual status.
	An analysis of these loans for 2014 is as follows (dollars in thousands):
	Balance at December 31, 2013	$	19,227

	Defined Benefit Plan
	The Company previously maintained a non-contributory defined benefit pension plan which covered substantially all employees who were 21 years of age or older and who had at least one year of service.  The Company froze its pension plan to new participants and converted its pension plan to a cash balance plan effective December 31, 2009.  Each year existing participants will receive, with some adjustments, income based on the yield of the 10 year U.S. Treasury Note in December of the preceding year.

	The plan sponsor selected the expected long-term rate-of-return-on-assets assumption in consultation with their investment advisors and actuary.  This rate was intended to reflect the average rate of earnings expected to be earned on the funds invested or to be invested to provide plan benefits.  Historical performance is reviewed, especially with respect to real rates of return (net of inflation), for the major asset classes held or anticipated to be held by the trust, and for the trust itself.  Undue weight is not given to recent experience that may not continue over the measurement period, with higher significance placed on current forecasts of future long-term economic conditions.
	Because assets are held in a qualified trust, anticipated returns are not reduced for taxes.  Further, solely for this purpose, the plan is assumed to continue in force and not terminate during the period in which assets are invested.  However, consideration is given to the potential impact of current and future investment policy, cash flow into and out of the trust, and expenses (both investment and non-investment) typically paid from plan assets (to the extent such expenses are not explicitly estimated within periodic cost).
	Below is a description of the plan's assets.  The plan's weighted-average asset allocations by asset category are as follows as of December 31, 2014 and 2013:
	Asset Category	December 31,

	Cash and Accrued Income			27.2	%			3.4	%
	Total			100	%			100	%
	The investment policy and strategy for plan assets can best be described as a growth and income strategy.  Diversification is accomplished by limiting the holding of any one equity issuer to no more than 5% of total equities.  Exchange traded funds are used to provide diversified exposure to the small capitalization and international equity markets.  All fixed income investments are rated as investment grade, with the majority of these assets invested in corporate issues.  The assets are managed by the Company's Trust and Investment Services Division.  No derivatives are used to manage the assets.  Equity securities do not include holdings in the Company.

401(k) Plan
The Company maintains a 401(k) plan that covers substantially all full-time employees of the Company. The Company matches a portion of the contribution made by employee participants after at least one year of service. The Company contributed $521,000, $542,000, and $568,000 to the 401(k) plan in 2014, 2013, and 2012, respectively. These amounts are included in employee benefits expense for the respective years.
Deferred Compensation Arrangements
The Company maintains deferred compensation agreements with certain current and former employees providing for annual payments to each ranging from $25,000 to $50,000 per year for ten years upon their retirement.  The liabilities under these agreements are being accrued over the officers' remaining periods of employment so that, on the date of their retirement, the then-present value of the annual payments would have been accrued.  The expense for these agreements was $10,000, $13,000, and $15,000 for the years 2014, 2013, and 2012, respectively.
Profit Sharing and Incentive Arrangements
The Company maintains a cash profit sharing plan for full-time employees based on the Company's performance and a cash incentive compensation plan for officers based on the Company's performance and individual officer goals.  The total amount charged to salary expense for these plans was $851,000, $890,000, and $1,086,000 for the years 2014, 2013, and 2012, respectively.

Fair Value Measurements [Abstract]
Fair Value Measurements	Note 19 – Fair Value Measurements
	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).
	In mid-2013, the Company purchased $1,000,000 in convertible preferred stock from a Virginia based, publicly traded community bank. There is no secondary market for this bank's preferred stock; however its common stock is traded on a limited basis in the over the counter market. The Company uses an independent third party to assist in the valuation of these securities.  Given the convertible nature of the securities, the common stock of the issuing community bank is used as a proxy for the preferred stock value.  This is the only security recorded with a Level 3 valuation at December 31, 2014.
	The following table presents the balances of financial assets 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 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 years ended December 31, 2014 and 2013. 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 comparable 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 impaired loans.  Any fair value adjustments are recorded in the period incurred as a valuation allowance against other real estate owned with the associated expense included in foreclosed real estate expense on the Consolidated Statements of Income.
	The following table summarizes the Company's assets that were measured at fair value on a nonrecurring basis during the period (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.
Restricted stock.  The carrying value of restricted stock approximates fair value based on the redemption provisions of the respective entity.
Loans held for sale.  The carrying amount is at 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 value 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 December 31, 2014 and 2013, the fair value of off balance sheet instruments was deemed immaterial, and therefore was not included in the table above.  The various off-balance sheet instruments were discussed in Note 16.
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.

Dividend Restrictions and Regulatory Capital [Abstract]
Dividend Restrictions and Regulatory Capital	Note 20 – Dividend Restrictions and Regulatory Capital
	The approval of the Comptroller of the Currency is required if the total of all dividends declared by a national bank in any calendar year exceeds the bank's retained net income, as defined, for that year combined with its retained net income for the preceding two calendar years.  Under this formula, the Bank can distribute as dividends to the Company, without the approval of the Comptroller of the Currency, $12,544,000 as of December 31, 2014.
	The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies.  Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company's and the Bank's financial statements.  Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices.  The capital amounts and classification are subject to qualitative judgments by the regulators concerning components, risk weighting, and other factors.  Prompt corrective action provisions are applicable to banks and not applicable to bank holding companies.
	The guidelines in effect for the periods reported, total capital is defined as core ("Tier 1") capital and supplementary ("Tier 2") capital less certain specified deductions from total capital such as reciprocal holdings of depository institution capital instruments and equity investments.  At least half of the total capital is required to be Tier 1 capital, which consists principally of common and certain qualifying preferred shareholders' equity (including trust preferred securities), less certain intangibles and other adjustments.  The remainder, Tier 2 capital, consists of cumulative preferred stock, long-term perpetual preferred stock, a limited amount of subordinated and other qualifying debt (including certain hybrid capital instruments) and a limited amount of the general loan loss allowance. The definition of assets has been modified to include items on and off the balance sheet, with each item being assigned a "risk-weight" for the determination of the ratio of capital to risk-adjusted assets.  Management believes, as of December 31, 2014 and 2013, that the Company and the Bank met the requirements to be considered "well capitalized."
	The following table provides summary information regarding regulatory capital (dollars in thousands):

	In July 2013, the federal banking agencies issued final rules that make technical changes to their capital rules to align them with the Basel III regulatory capital framework and meet certain requirements of the Dodd-Frank Act.  Effective January 1, 2015, the final rules require the Company and the Bank to comply with the following new minimum capital ratios: (i) a new common equity Tier 1 capital ratio of 4.5% of risk-weighted assets; (ii) a Tier 1 capital ratio of 6.0% of risk-weighted assets (increased from the prior requirement of 4.0%); (iii) a total capital ratio of 8.0% of risk-weighted assets (unchanged from prior requirement); and (iv) a leverage ratio of 4.0% of total assets (unchanged from the prior requirement).  These are the initial capital requirements, which will be phased in over a four-year period.  When fully phased in on January 1, 2019, the rules will require the Company and the Bank to maintain (i) a minimum ratio of common equity Tier 1 to risk-weighted assets of at least 4.5%, plus a 2.5% "capital conservation buffer" (which is added to the 4.5% common equity Tier 1 ratio as that buffer is phased in, effectively resulting in a minimum ratio of common equity Tier 1 to risk-weighted assets of at least 7.0% upon full implementation), (ii) a minimum ratio of Tier 1 capital to risk-weighted assets of at least 6.0%, plus the 2.5% capital conservation buffer (which is added to the 6.0% Tier 1 capital ratio as that buffer is phased in, effectively resulting in a minimum Tier 1 capital ratio of 8.5% upon full implementation), (iii) a minimum ratio of total capital to risk-weighted assets of at least 8.0%, plus the 2.5% capital conservation buffer (which is added to the 8.0% total capital ratio as that buffer is phased in, effectively resulting in a minimum total capital ratio of 10.5% upon full implementation), and (iv) a minimum leverage ratio of 4.0%, calculated as the ratio of Tier 1 capital to average assets.
	The capital conservation buffer requirement will be phased in beginning January 1, 2016, at 0.625% of risk-weighted assets, increasing by the same amount each year until fully implemented at 2.5% on January 1, 2019.  The capital conservation buffer is designed to absorb losses during periods of economic stress.  Banking institutions with a ratio of common equity Tier 1 to risk-weighted assets above the minimum but below the conservation buffer will face constraints on dividends, equity repurchases, and compensation based on the amount of the shortfall.
	If the new capital ratios described above had been effective as of December 31, 2014, based on management's interpretation and understanding of the new rules, the Company and the Bank would have remained "well capitalized" as of such date.

Segment and Related Information [Abstract]
Segment and Related Information	Note 21 – Segment and Related Information
	The Company has two reportable segments, community banking and 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 community banking.
	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 division receives fees for investment and administrative services.
	Amounts shown in the "Other" column include activities of the Company which are primarily debt service on trust preferred securities and corporate items.  Intersegment eliminations primarily consist of the Company's interest income on deposits held by the Bank.
	Segment information as of and for the years ended December 31, 2014, 2013, and 2012, is shown in the following table (dollars in thousands):

	Substantially all the Company's loans are made within its market area, which includes Southern and Central Virginia and the northern portion of Central North Carolina.  The ultimate collectibility of the Company's loan portfolio and the ability to realize the value of any underlying collateral, if necessary, are impacted by the economic conditions and real estate values of the market area.
	Loans secured by real estate were $708,703,000, or 84.3% of the loan portfolio at December 31, 2014, and $666,152,000, or 83.8% of the loan portfolio at December 31, 2013.  Loans secured by commercial real estate represented the largest portion of loans at $391,472,000 at December 31, 2014 and $364,616,000 at December 31, 2013, 46.6% and 45.9%, respectively of total loans.  While there were no concentrations of loans to any individual, group of individuals, business, or industry that exceeded 10% of total loans at December 31, 2014 or 2013, loans to lessors of nonresidential buildings represented 16.7% of total loans at December 31, 2014 and 11.8% at December 31, 2013; the lessees and lessors are engaged in a variety of industries.

Subsequent Events	Note 26. SUBSEQUENT EVENTS
	The Company's management has evaluated subsequent events through March 9, 2015, the date the financial statements were available to be issued.
	Acquisition of MainStreet BankShares, Inc.
	On January 1, 2015, American National completed its acquisition of MainStreet BankShares, Inc. ("MainStreet"). The merger of MainStreet with and into American National was effected pursuant to the terms and conditions of the Agreement and Plan of Reorganization, dated as of August 24, 2014, between American National 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 American National Bank and Trust Company, American National's wholly-owned bank subsidiary. Pursuant to the Merger Agreement, holders of shares of MainStreet common stock have a right to receive $3.46 in cash and 0.482 shares of American National 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 American National common stock, adjusted based on a 0.643 exchange ratio. Each share of American National 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 million from American National Bank to American National, and no borrowing was incurred by American National or American National Bank in connection with the Merger.
	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. The following table provides a preliminary assessment of the assets purchased, liabilities assumed and the consideration transferred (dollars in thousands, except share and per share data):
	Preliminary Schedule of consideration paid, and the fair value of identifiable assets acquired and liabilities assumed
	Consideration Paid:
	Common shares issued (825,586)		$	20,483
	Cash paid to Shareholders			5,935
	Value of consideration			26,418
	Assets acquired:
	Cash and cash equivalents			18,173
	Investment securities			19,387
	Loans, net of unearned income			115,141
	Premises and equipment, net			1,401
	Deferred income taxes			2,761
	Core deposit intangible			1,839
	Other real estate owned			168
	Other assets			3,097
	Total assets			161,967
	Liabilities assumed:
	Deposits			137,323
	Other liabilities			3,001
	Total Liabilities			140,324
	Net assets acquired			21,643
	Preliminary goodwill resulting from merger with MainStreet		$	4,775
	The estimated fair values of the assets acquired and liabilities assumed at the acquisition date, presented in the table above, include some amounts that are based on preliminary fair value estimates. The following factors led to certain balances having preliminary fair value estimates:
		·	The Company engaged third party specialists to assist in valuing certain assets and liabilities and this work (including management's review and approval) is not yet complete;
		·	The proximity of the acquisition date (January 1, 2015) and the date that the Company's financial statements were issued (March 9, 2015); and
		·	The audit of MainStreet's opening balance sheet has not been completed.
	In many cases, determining the fair value of the acquired assets and assumed liabilities required the Company to estimate cash flows expected to result from those assets and liabilities and to discount those cash flows at appropriate rates of interest. The most significant of those determinations related to the fair valuation of acquired loans. For such loans, the excess of cash flows expected at acquisition over the estimated fair value is recognized as interest income over the remaining lives of the loans. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition reflects the impact of estimated credit losses and other factors, such as prepayments. In accordance with GAAP, there was no carry-over of MainStreet's previously established allowance for credit losses.
	The acquired loans were divided into loans with evidence of credit quality deterioration which are accounted for under ASC 310-30, Receivables – Loans and Debt Securities Acquired with Deteriorated Credit Quality, (acquired impaired), and loans that do not meet this criteria, which are accounted for under ASC 310-20, Receivables – Nonrefundable Fees and Other Costs, (acquired performing). In addition, the loans are further categorized into different loan pools per loan types. The Company determined expected cash flows on the acquired loans based on the best available information at the date of acquisition. If material new information is obtained about facts and circumstances about expected cash flows that existed as of the acquisition date, management will adjust accordingly in accordance with accounting for business combinations.
	The fair values of the acquired performing loans were$ 105,874,000 and the fair values of the acquired impaired loans were $9,267,000. The gross contractually required principal and interest payments receivable for acquired performing loans was$ 131,865,000. The best estimate of contractual cash flows not expected to be collected related to the acquired performing loans is $7,104,000.
	The following table presents the acquired impaired loans receivable at the acquisition date (dollars in thousands):
	Contractually required principal and interest at acquisition		$	13,504
	Contractual cash flows not expected to be collected (nonaccretable difference)			2,993
	Expected cash flows at acquisition			10,511
	Interest component of expected cash flows (accretable discount)			1,244
	Fair value of acquired impaired loans accounted for under FASB ASC 310-30		$	9,267
	The amounts of MainStreet's revenue and earnings included in the Company's Consolidated Statement of Income for the year ended December 31, 2014, and the revenue and earnings of the combined entity had the acquisition date been January 1, 2013, are presented in the pro forma table below. These results combine the historical results of MainStreet into the Company's Consolidated Statement of Income, and while certain adjustments were made for the estimated impact of certain fair value adjustments and other acquisition-related activity, they are not indicative of what would have occurred had the acquisition taken place on January 1, 2012. In particular, no adjustments have been made to adjust provision for loan losses in 2014 on the acquired loan portfolio and related income taxes. In addition, expenses related to systems conversions and other costs of integration are expected to be recorded during 2014 and those costs will be expensed as incurred. The Company expects to achieve further operating cost savings and other business synergies, including branch closures, as a result of the acquisition which are not reflected in the pro forma amounts below (dollars in thousands):

Summary of Significant Accounting Policies [Abstract]
Nature of Operations and Consolidation	Nature of Operations and Consolidation
	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, goodwill and intangible assets, other than temporary impairment, the valuation of deferred tax assets and liabilities, and the valuation of foreclosed real estate.
	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") pursuant to the terms and conditions of the Agreement and Plan of Reorganization, dated December 15, 2010, between the Company and MidCarolina.  MidCarolina was headquartered in Burlington, North Carolina, and engaged in banking operations through its subsidiary bank, MidCarolina Bank.  The transaction has expanded the Company's footprint in North Carolina, adding eight branches in Alamance and Guilford Counties.
	In July 2011, and in connection with its acquisition of MidCarolina Financial Corporation, the Company assumed the liabilities of the MidCarolina Trust I and MidCarolina Trust II, two separate Delaware statutory trust (the "MidCarolina Trusts"), which were also formed for the purpose of issuing preferred securities.  Refer to Note 12 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 12.
Cash and Cash Equivalents	Cash and Cash Equivalents
	Cash includes cash on hand, cash with correspondent banks, and cash on deposit at the Federal Reserve Bank of Richmond.  Cash equivalents are short-term, highly liquid investments that are readily convertible to cash with original maturities of three months or less and are subject to an insignificant risk of change in value.  Cash and cash equivalents are carried at cost.
Interest-bearing Deposits in Other Banks	Interest-bearing Deposits in Other Banks
	Interest-bearing deposits in other banks mature within one year and are carried at cost.
Securities	Securities
	Certain debt securities that management has the positive intent and ability to hold to maturity are classified as "held to maturity" and recorded at amortized cost. Trading securities are recorded at fair value with changes in fair value included in earnings. Securities not classified as held to maturity or trading, including equity securities with readily determinable fair values, are classified as "available for sale" and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method.
	The Company does not currently have any securities in held to maturity or trading and has no plans to add any to either category.
	The Company follows accounting guidance related to recognition and presentation of other-than-temporary impairment. The guidance specifies that (1) if a company does not have the intent to sell a debt security prior to recovery and (2) it is more likely than not that it will not have to sell the debt security prior to recovery, the security would not be considered other-than-temporarily impaired, unless there is a credit loss. When an entity does not intend to sell the security and it is more likely than not the entity will not have to sell the security before recovery of its cost basis, it will recognize the credit component of an other-than-temporary impairment of a debt security in earnings and the remaining portion in other comprehensive income. For held-to-maturity debt securities, the amount of an other-than-temporary impairment recorded in other comprehensive income for the noncredit portion of a previous other-than-temporary impairment should be amortized prospectively over the remaining life of the security on the basis of the timing of future estimated cash flows of the security.
	For equity securities, when the Company has decided to sell an impaired available-for-sale security and the entity does not expect the fair value of the security to fully recover before the expected time of sale, the security is deemed other-than-temporarily impaired in the period in which the decision to sell is made. The Company recognizes an impairment loss when the impairment is deemed other-than-temporary even if a decision to sell has not been made.
	Due to the nature and restrictions placed on the Company's investment in common stock of the Federal Home Loan Bank of Atlanta ("FHLB") and the Federal Reserve Bank of Richmond, these securities have been classified as restricted equity securities and carried at cost.
Loans Held for Sale	Loans Held for Sale
	Secondary market mortgage loans are designated as held for sale at the time of their origination.  These loans are pre-sold with servicing released and the Company does not retain any interest after the loans are sold.  These loans consist primarily of fixed-rate, single-family residential mortgage loans which meet the underwriting characteristics of certain government-sponsored enterprises (conforming loans).  In addition, the Company requires a firm purchase commitment from a permanent investor before a loan can be committed, thus limiting interest rate risk.  Loans held for sale are carried at fair value.  Gains on sales of loans are recognized at the loan closing date and are included in noninterest income.
Derivative Loan Commitments	Derivative Loan Commitments
	The Company enters into mortgage loan commitments whereby the interest rate on the loan is determined prior to funding (rate lock commitments).  Mortgage loan commitments are referred to as derivative loan commitments if the loan that will result from exercise of the commitment will be held for sale upon funding.  Loan commitments that are derivatives are recognized at fair value on the consolidated balance sheets with net changes in their fair values recorded in other expenses.  Derivative loan commitments resulted in no income or loss for 2014, 2013 or 2012.
	The period of time between issuance of a loan commitment and sale of the loan generally ranges from 30 to 60 days. The Company protects itself from changes in interest rates through the use of best efforts forward delivery contracts, by committing to sell a loan at the time the borrower commits to an interest rate with the intent that the buyer has assumed the interest rate risk on the loan.  As a result, the Company is not generally exposed to significant losses nor will it realize significant gains related to its rate lock commitments due to changes in interest rates.  The correlation between the rate lock commitments and the best efforts contracts is very high due to their similarity.
	The market value of rate lock commitments and best efforts contracts is not readily ascertainable with precision because rate lock commitments and best efforts contracts are not actively traded in stand-alone markets.  The Company determines the fair value of rate lock commitments and best efforts contracts by measuring the change in the estimated value of the underlying assets while taking into consideration the probability that the loan will be funded.
Loans	Loans
	The Company makes mortgage, commercial, and consumer loans.  A substantial portion of the loan portfolio is secured by real estate.  The ability of the Company's debtors to honor their contracts is dependent upon the real estate market and general economic conditions in the Company's market area.
	Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off, generally are reported at their outstanding unpaid principal balance adjusted for the allowance for loan losses, and any deferred fees or costs.  Interest income is accrued on the unpaid principal balance.  Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method.
	The accrual of interest on loans is generally discontinued at the time the loan is 90 days delinquent unless the credit is well-secured and in process of collection.  Loans are typically charged off when the loan is 120 days past due, unless secured and in process of collection.  Loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful.
	Interest accrued but not collected for loans that are placed on nonaccrual status or charged-off is reversed against interest income.  The interest on these loans is accounted for on the cash basis or cost recovery method, until qualifying for return to accrual status.  Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
	A loan is considered past due when a payment of principal or interest or both is due but not paid.  Management closely monitors past due loans in timeframes of 30-59 days, 60-89 days, and 90 or more days past due.
	These policies apply to all loan portfolio classes and segments.
	Substandard and doubtful risk graded commercial, commercial real estate, and construction loans equal to or greater than $100,000 on an unsecured basis, and equal to or greater than $250,000 on a secured basis are reviewed for impairment. All troubled debt restructurings, regardless of dollar amount, are also evaluated for impairment. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement.  Factors considered by management in determining impairment and establishing a specific allowance include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due.  Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower's prior payment record, and the amount of the shortfall in relation to the principal and interest owed.  Impairment is measured on a loan-by-loan basis for commercial, commercial real estate, and construction loans by either the present value of expected future cash flows discounted at the loan's effective interest rate, the loan's obtainable market price, or the fair value of the collateral if the loan is collateral dependent.
	Generally, large groups of smaller balance homogeneous loans (residential real estate and consumer loans) are collectively evaluated for impairment.  The Company's policy for recognizing interest income on impaired loans is consistent with its nonaccrual policy.
	The Company's loan portfolio is organized by major segment. These include:  commercial, commercial real estate, residential real estate and consumer loans.  Each segment has particular risk characteristics that are specific to the borrower and the generic category of credit.  Commercial loan repayments are highly dependent on cash flows associated with the underlying business and its profitability.  They can also be impacted by changes in collateral values.  Commercial real estate loans share the same general risk characteristics as commercial loans, but are often more dependent on the value of the underlying real estate collateral and, when construction is involved, the ultimate completion of and sale of the project.  Residential real estate loans are generally dependent on the value of collateral and the credit worthiness of the underlying borrower.  Consumer loans are very similar in risk characteristics to residential real estate.
	In connection with the MidCarolina merger, certain loans were acquired which exhibited deteriorated credit quality since origination and for which the Bank does not expect to collect all contractual payments.  These purchased credit impaired loans are recorded at the amount paid, such that there is no carryover of the seller's allowance for loan losses.  After acquisition, losses are recognized by an increase in the allowance for loan losses.
	Such purchased credit impaired loans are accounted for individually or aggregated into pools of loans based on common risk characteristics such as, credit score, loan type, and date of origination.  The Company estimates the amount and timing of expected cash flows for each loan or pool, and the expected cash flows in excess of amount paid is recorded as interest income over the remaining life of the loan or pool (accretable yield).  The excess of the loan's or pool's contractual principal and interest over expected cash flows is not recorded (nonaccretable difference).
	Over the life of the loan or pool, expected cash flows continue to be estimated.  It the present value of expected cash flows is less than the carrying amount, a loss is recorded as a provision for loan losses.  If the present value of expected cash flows is greater than the carrying amount, it is recognized as part of future interest income.
Troubled Debt Restructurings	Troubled Debt Restructurings
	In situations where, for economic or legal reasons related to a borrower's financial condition, management may grant a concession to the borrower that it would not otherwise consider, the related loan is classified as a troubled debt restructuring ("TDR").  Management strives to identify borrowers in financial difficulty early and work with them to modify their loan to more affordable terms before their loan reaches nonaccrual status.  These modified terms may include rate reductions, principal forgiveness, payment forbearance and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of the collateral.  In cases where borrowers are granted new terms that provide for a reduction of either interest or principal, management measures any impairment on the restructuring as noted above for impaired loans.  The Company has $2,862,000 in loans classified as TDRs as of December 31, 2014 and $2,100,000 as of December 31, 2013.
Allowance for Loan Losses	Allowance for Loan Losses
	The purpose of the allowance for loan losses ("ALLL") is to provide for probable losses inherent in the loan portfolio.  The allowance is increased by the provision for loan losses and by recoveries of previously charged-off loans.  Loan charge-offs decrease the allowance.
	The goal of the Company is to maintain an appropriate, systematic, and consistently applied process to determine the amounts of the ALLL and the provision for loan loss expense.
	The Company uses certain practices to manage its credit risk.  These practices include (1) appropriate lending limits for loan officers, (2) a loan approval process, (3) careful underwriting of loan requests, including analysis of borrowers, cash flows, collateral, and market risks, (4) regular monitoring of the portfolio, including diversification by type and geography, (5) review of loans by the Loan Review department, which operates independently of loan production, (6) regular meetings of the Credit Committees to discuss portfolio and policy changes and make decisions on large or unusual loan requests, and (7) regular meetings of the Asset Quality Committee which reviews the status of individual loans.
	Risk grades are assigned as part of the loan origination process. From time to time risk grades may be modified as warranted by the facts and circumstances surrounding the credit.
	Calculation and analysis of the allowance for loan losses is prepared quarterly by the Finance Department.  The Company's Credit Committee, Capital Management Committee, Audit Committee, and the Board of Directors review the allowance for adequacy.
	The Company's allowance for loan losses has two basic components:  the formula allowance and the specific allowance.  Each of these components is determined based upon estimates and judgments.
	The formula allowance uses historical loss experience as an indicator of future losses, along with various qualitative factors, including levels and trends in delinquencies, nonaccrual loans, charge-offs and recoveries, trends in volume and terms of loans, effects of changes in underwriting standards, experience of lending staff, economic conditions, and portfolio concentrations. In the formula allowance for commercial and commercial real estate loans, the historical loss rate is combined with the qualitative factors, resulting in an adjusted loss factor for each risk-grade category of loans.  The period-end balances for each loan risk-grade category are multiplied by the adjusted loss factor.  Allowance calculations for consumer loans are calculated based on historical losses for each product category without regard to risk grade. This loss rate is combined with qualitative factors resulting in an adjusted loss factor for each product category.
	The specific allowance uses various techniques to arrive at an estimate of loss for specifically identified impaired loans. These include:
	·	The present value of expected future cash flows discounted at the loan's effective interest rate.  The effective interest rate on a loan is the rate of return implicit in the loan (that is, the contractual interest rate adjusted for any net deferred loan fees or costs and any premium or discount existing at the origination or acquisition of the loan);
	·	The loan's observable market price, or
	·	The fair value of the collateral, net of estimated costs to dispose, if the loan is collateral dependent.
	The use of these computed values is inherently subjective and actual losses could be greater or less than the estimates.
	No single statistic, formula, or measurement determines the adequacy of the allowance.  Management makes subjective and complex judgments about matters that are inherently uncertain, and different amounts would be reported under different conditions or using different assumptions.  For analytical purposes, management allocates a portion of the allowance to specific loan categories and specific loans.  However, the entire allowance is used to absorb credit losses inherent in the loan portfolio, including identified and unidentified losses.
	The relationships and ratios used in calculating the allowance, including the qualitative factors, may change from period to period as facts and circumstances evolve.  Furthermore, management cannot provide assurance that in any particular period the Company will not have sizeable credit losses in relation to the amount reserved.  Management may find it necessary to significantly adjust the allowance, considering current factors at the time.
Premises and Equipment	Premises and Equipment
	Land is carried at cost.  Premises and equipment are stated at cost, less accumulated depreciation and amortization.  Premises and equipment are depreciated over their estimated useful lives ranging from three years to thirty-nine years; leasehold improvements are amortized over the lives of the respective leases or the estimated useful lives of the improvements, whichever is less.  Software is generally amortized over three years.  Depreciation and amortization are recorded on the straight-line method.
	Costs of maintenance and repairs are charged to expense as incurred.  Costs of replacing structural parts of major units are considered individually and are expensed or capitalized as the facts dictate.  Gains and losses on routine dispositions are reflected in current operations.
Goodwill and Intangible Assets	Goodwill and Intangible Assets
	Goodwill is subject to at least an annual assessment for impairment by applying a fair value based test.  Additionally, acquired intangible assets (such as core deposit intangibles) are separately recognized if the benefit of the assets can be sold, transferred, licensed, rented, or exchanged, and amortized over their useful lives.  Intangible assets related to branch transactions continued to amortize. The cost of purchased deposit relationships and other intangible assets, based on independent valuation, are being amortized over their estimated lives ranging from eight to ten years.
	The Company records as goodwill the excess of 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 during the years ended December 31, 2014, 2013, and 2012.
Trust Assets	Trust Assets
	Securities and other property held by the trust and investment services segment in a fiduciary or agency capacity are not assets of the Company and are not included in the accompanying consolidated financial statements.
Other Real Estate Owned	Other Real Estate Owned
	Other real estate owned represents real estate that has been acquired through loan foreclosures or deeds received in lieu of loan payments. Generally, such properties are appraised at the time acquired, and are recorded at the fair value less estimated selling costs.  Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in noninterest expense.
Transfers of Financial Assets	Transfers of Financial Assets
	Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered.  Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company – put presumptively beyond reach of the transferor and its creditors, even in bankruptcy or other receivership, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets.
Income Taxes	Income Taxes
	The Company uses the balance sheet method to account for deferred income tax assets and liabilities.  Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws.
	When tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained.  The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any.  Tax positions taken are not offset or aggregated with other positions.  Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority.  The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits in the accompanying consolidated balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination.  The Company had no liability for unrecognized tax benefits as of December 31, 2014 and 2013.
Stock-Based Compensation	Stock-Based Compensation
	Stock compensation accounting guidance ASC 718, "Compensation – Stock Compensation" requires that the compensation cost relating to share-based payment transactions be recognized in financial statements.  That cost will be measured based on the grant date fair value of the equity or liability instruments issued.  The stock compensation accounting guidance covers a wide range of share-based compensation arrangements including stock options, restricted share plans, performance-based awards, share appreciation rights, and employee share purchase plans.
	The stock compensation accounting guidance requires that compensation cost for all stock awards be calculated and recognized over the employees' service period, generally defined as the vesting period.  For awards with graded-vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award.  A Black-Scholes model is used to estimate the fair value of stock options, while the market price of the Company's common stock at the date of grant is used for restricted stock awards.
Earnings Per Common Share	Earnings Per Common Share
	Basic earnings per common share represent income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per common share reflect the impact of additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Company consist solely of outstanding stock options, and are determined using the treasury method. Nonvested shares of restricted stock are included in the computation of basic earning per share because the holder has voting rights and shares in non-forfeitable dividends during the vesting period.
Comprehensive Income	Comprehensive Income
	Comprehensive income is shown in a two statement approach, the first statement presents total net income and its components followed by a second statement that presents all the components of other comprehensive income such as unrealized gains and losses on available for sale securities and changes in the funded status of a defined benefit postretirement plan.
Advertising and Marketing Costs	Advertising and Marketing Costs
	Advertising and marketing costs are expensed as incurred, and were $453,000, $607,000, and $454,000 in 2014, 2013, and 2012, respectively.
Reclassifications	Reclassifications
	Certain reclassifications have been made in prior years financial statements to conform to classifications used in the current year. There were no material reclassifications.
Use of Estimates	Use of Estimates
	In preparing consolidated financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and 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.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In January 2014, the FASB issued Accounting Standards Update ("ASU") 2014-01, "Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects (a consensus of the FASB Emerging Issues Task Force)."  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 Company is currently assessing the impact that ASU 2014-01 will have on its consolidated financial statements.
	In January 2014, the FASB issued ASU 2014-04, "Receivables—Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure (a consensus of the FASB Emerging Issues Task Force)."  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 Company is currently assessing the impact that ASU 2014-04 will have on its consolidated financial statements.
	In April 2014, the FASB issued ASU 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." The amendments in this ASU change the criteria for reporting discontinued operations while enhancing disclosures in this area. Under the new guidance, only disposals representing a strategic shift in operations should be presented as discontinued operations. Those strategic shifts should have a major effect on the organization's operations and financial results and include disposals of a major geographic area, a major line of business, or a major equity method investment. The new guidance requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. Additionally, the new guidance requires disclosure of the pre-tax income attributable to a disposal of a significant part of an organization that does not qualify for discontinued operations reporting. The amendments in the ASU are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. Early adoption is permitted.  The Company does not expect the adoption of ASU 2014-08 to have a material impact on its 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. 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 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 its 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 Company is currently assessing the impact that ASU 2014-11 will have on its consolidated financial statements.
	In June 2014, the FASB issued ASU No. 2014-12, "Compensation – Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period." The new guidance applies to reporting entities that grant employees share-based payments in which the terms of the award allow a performance target to be achieved after the requisite service period. The amendments in the ASU require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition.  Existing guidance in "Compensation – Stock Compensation (Topic 718)," should be applied to account for these types of awards. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted and reporting entities may choose to apply the amendments in the ASU either on a prospective or retrospective basis.  The Company is currently assessing the impact that ASU 2014-12 will have on its 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 Company is currently assessing the impact that ASU 2014-14 will have on its 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 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 November 2014, the FASB issued ASU No. 2014-17, "Business Combinations (Topic 805):  Pushdown Accounting."  The amendments in ASU provide an acquired entity with an option to apply pushdown accounting in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity.  An acquired entity may elect the option to apply pushdown accounting in the reporting period in which the change-in-control event occurs. An acquired entity should determine whether to elect to apply pushdown accounting for each individual change-in-control event in which an acquirer obtains control of the acquired entity. If pushdown accounting is not applied in the reporting period in which the change-in-control event occurs, an acquired entity will have the option to elect to apply pushdown accounting in a subsequent reporting period to the acquired entity's most recent change-in-control event. An election to apply pushdown accounting in a reporting period after the reporting period in which the change-in-control event occurred should be considered a change in accounting principle in accordance with Topic 250, Accounting Changes and Error Corrections. If pushdown accounting is applied to an individual change-in-control event, that election is irrevocable.  The amendments in this ASU are effective on November 18, 2014. After the effective date, an acquired entity can make an election to apply the guidance to future change-in-control events or to its most recent change-in-control event. However, if the financial statements for the period in which the most recent change-in-control event occurred already have been issued or made available to be issued, the application of this guidance would be a change in accounting principle.  The Company does not expect the adoption of ASU 2014-17 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.

Amortized cost and estimated fair value of investments in securities by contractual maturity	The amortized cost and estimated fair value of investments in securities at December 31, 2014, by contractual maturity, are shown in the following table.  Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.  Because mortgage-backed securities have both known principal repayment terms as well as unknown principal repayments due to potential borrower pre-payments, it is difficult to accurately predict the final maturity of these investments.  Mortgage-backed securities are shown separately (dollars in thousands):

	In July 2013, the federal banking agencies issued final rules that make technical changes to their capital rules to align them with the Basel III regulatory capital framework and meet certain requirements of the Dodd-Frank Act.  Effective January 1, 2015, the final rules require the Company and the Bank to comply with the following new minimum capital ratios: (i) a new common equity Tier 1 capital ratio of 4.5% of risk-weighted assets; (ii) a Tier 1 capital ratio of 6.0% of risk-weighted assets (increased from the prior requirement of 4.0%); (iii) a total capital ratio of 8.0% of risk-weighted assets (unchanged from prior requirement); and (iv) a leverage ratio of 4.0% of total assets (unchanged from the prior requirement).  These are the initial capital requirements, which will be phased in over a four-year period.  When fully phased in on January 1, 2019, the rules will require the Company and the Bank to maintain (i) a minimum ratio of common equity Tier 1 to risk-weighted assets of at least 4.5%, plus a 2.5% "capital conservation buffer" (which is added to the 4.5% common equity Tier 1 ratio as that buffer is phased in, effectively resulting in a minimum ratio of common equity Tier 1 to risk-weighted assets of at least 7.0% upon full implementation), (ii) a minimum ratio of Tier 1 capital to risk-weighted assets of at least 6.0%, plus the 2.5% capital conservation buffer (which is added to the 6.0% Tier 1 capital ratio as that buffer is phased in, effectively resulting in a minimum Tier 1 capital ratio of 8.5% upon full implementation), (iii) a minimum ratio of total capital to risk-weighted assets of at least 8.0%, plus the 2.5% capital conservation buffer (which is added to the 8.0% total capital ratio as that buffer is phased in, effectively resulting in a minimum total capital ratio of 10.5% upon full implementation), and (iv) a minimum leverage ratio of 4.0%, calculated as the ratio of Tier 1 capital to average assets.
	The capital conservation buffer requirement will be phased in beginning January 1, 2016, at 0.625% of risk-weighted assets, increasing by the same amount each year until fully implemented at 2.5% on January 1, 2019.  The capital conservation buffer is designed to absorb losses during periods of economic stress.  Banking institutions with a ratio of common equity Tier 1 to risk-weighted assets above the minimum but below the conservation buffer will face constraints on dividends, equity repurchases, and compensation based on the amount of the shortfall.
	If the new capital ratios described above had been effective as of December 31, 2014, based on management's interpretation and understanding of the new rules, the Company and the Bank would have remained "well capitalized" as of such date.
