Accounting Policies [Abstract]
Accounting Policies	Accounting Policies 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 consolidated 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, unfunded pension liability, other-than-temporary impairment of securities, accounting for merger and acquisition activity, accounting for acquired loans with specific credit-related deterioration, the valuation of deferred tax assets and liabilities, and the valuation of other real estate owned ("OREO"). 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 8. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments (consisting of normal recurring accruals) necessary to present fairly the results of the interim periods. The results of operations for the interim periods are not necessarily indicative of the results that may occur for any other period. Certain reclassifications have been made to prior period balances to conform to the current period presentation. These reclassifications did not have an impact on net income and were considered immaterial. These statements should be read in conjunction with the Notes to Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2016 . Adoption of New Accounting Standard During the first quarter of 2017, the Company adopted Accounting Standards Update ("ASU") 2016-09, "Compensation-Stock Compensation (Topic 718): Improvements to Employer Share- Based Payment Accounting." This ASU simplifies several aspects of the accounting for share-based payment award transactions, one of which is the recognition of excess tax benefits and deficiencies related to share-based payments, including tax benefits of dividends on share-based payment awards. Prior to the adoption of ASU 2016-09, such tax consequences were recognized as components of additional paid-in capital. With the adoption of this ASU, tax benefits and deficiencies are recognized within income tax expense. In accordance with the adoption provisions of ASU 2016-09, the results for the second quarter and first six months of 2016 include only the excess tax (expense) benefits attributable to the second quarter and first six months of 2016 in the amount of $2,000 and $50,000 , respectively. Recent Accounting Pronouncements In January 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." The amendments in ASU 2016-01, among other things: (1) requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; (2) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; (3) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables); and (4) eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently assessing the impact that ASU 2016-01 will have on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)." Among other things, in the amendments in ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee's right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company is currently assessing the impact that ASU 2016-02 will have on its consolidated financial statements. During June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." The amendments in this ASU, among other things, require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The amendments in this ASU are effective for Securities and Exchange Commission ("SEC") filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The Company is currently assessing the impact that ASU 2016-13 will have on its consolidated financial statements. During August 2016, the FASB issued ASU No. 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments", to address diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The amendments should be applied using a retrospective transition method to each period presented. If retrospective application is impractical for some of the issues addressed by the update, the amendments for those issues would be applied prospectively as of the earliest date practicable. Early adoption is permitted, including adoption in an interim period. The Company does not expect the adoption of ASU 2016-15 to have a material impact on its consolidated financial statements. During January 2017, the FASB issued ASU No. 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business". The amendments in this ASU clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. Under the current implementation guidance in Topic 805, there are three elements of a business-inputs, processes, and outputs. While an integrated set of assets and activities (collectively referred to as a "set") that is a business usually has outputs, outputs are not required to be present. In addition, all the inputs and processes that a seller uses in operating a set are not required if market participants can acquire the set and continue to produce outputs. The amendments in this ASU provide a screen to determine when a set is not a business. If the screen is not met, the amendments (1) require that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output and (2) remove the evaluation of whether a market participant could replace missing elements. The ASU provides a framework to assist entities in evaluating whether both an input and a substantive process are present. The amendments in this ASU are effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The amendments in this ASU should be applied prospectively on or after the effective date. No disclosures are required at transition. The Company does not expect the adoption of ASU 2017-01 to have a material impact on its consolidated financial statements. During January 2017, the FASB issued ASU No. 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment". The amendments in this ASU simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit's goodwill with the carrying amount of that goodwill. Instead, under the amendments in this ASU, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. Public business entities that are SEC filers should adopt the amendments in this ASU for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company does not expect the adoption of ASU 2017-04 to have a material impact on its consolidated financial statements. During March 2017, the FASB issued ASU 2017-07, "Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost." The amendments in this ASU require an employer that offers defined benefit pension plans, other postretirement benefit plans, or other types of benefits accounted for under Topic 715 to report the service cost component of net periodic benefit cost in the same line item(s) as other compensation costs arising from services rendered during the period. The other components of net periodic benefit cost are required to be presented in the income statement separately from the service cost component. If the other components of net periodic benefit cost are not presented on a separate line or lines, the line item(s) used in the income statement must be disclosed. In addition, only the service cost component will be eligible for capitalization as part of an asset, when applicable. The amendments are effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption is permitted. The Company does not expect the adoption of ASU 2017-07 to have a material impact on its consolidated financial statements. During March 2017, the FASB issued ASU 2017-08, "Receivables-Nonrefundable Fees and Other Costs (Subtopic 310‐20), Premium Amortization on Purchased Callable Debt Securities." The amendments in this ASU shorten the amortization period for certain callable debt securities purchased at a premium. Upon adoption of the standard, premiums on these qualifying callable debt securities will be amortized to the earliest call date. Discounts on purchased debt securities will continue to be accreted to maturity. The amendments are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. Upon transition, entities should apply the guidance on a modified retrospective basis, with a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption and provide the disclosures required for a change in accounting principle. The Company is currently assessing the impact that ASU 2017-08 will have on its consolidated financial statements. During May 2017, the FASB issued ASU 2017-09, "Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting." The amendments provide guidance on determining which changes to the terms and conditions of share-based payment awards require an entity to apply modification accounting under Topic 718. The amendments are effective for all entities for annual periods, including interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period, for reporting periods for which financial statements have not yet been issued. The Company is currently assessing the impact that ASU 2017-09 will have on its consolidated financial statements.

Securities	Securities The amortized cost and fair value of investments in debt and equity securities at June 30, 2017 and December 31, 2016 were as follows (dollars in thousands): June 30, 2017 Amortized Unrealized Unrealized Securities available for sale: Federal agencies and GSEs $ 93,406 $ 23 $ 1,737 $ 91,692 Mortgage-backed and CMOs 79,334 423 689 79,068 State and municipal 97,297 2,167 259 99,205 Corporate 8,108 212 5 8,315 Equity securities 1,288 935 — 2,223 Total securities available for sale $ 279,433 $ 3,760 $ 2,690 $ 280,503 December 31, 2016 Amortized Unrealized Unrealized Securities available for sale: Federal agencies and GSEs $ 106,379 $ 62 $ 2,387 $ 104,054 Mortgage-backed and CMOs 79,917 514 938 79,493 State and municipal 145,757 2,540 782 147,515 Corporate 13,392 123 23 13,492 Equity securities 1,288 660 — 1,948 Total securities available for sale $ 346,733 $ 3,899 $ 4,130 $ 346,502 Restricted Stock Due to restrictions placed upon the Bank's common stock investment in the Federal Reserve Bank of Richmond ("FRB") and Federal Home Loan Bank of Atlanta ("FHLB"), these securities have been classified as restricted equity securities and carried at cost. The restricted securities are not subject to the investment security classification and are included as a separate line item on the Company's Consolidated Balance Sheet. The FRB requires the Bank to maintain stock with a par value equal to 3.0% of its outstanding capital and an additional 3.0% is on call. 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 cost of restricted stock at June 30, 2017 and December 31, 2016 was as follows (dollars in thousands): June 30, December 31, FRB stock $ 3,573 $ 3,559 FHLB stock 1,928 2,665 Total restricted stock $ 5,501 $ 6,224 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 June 30, 2017 . 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 Unrealized Fair Unrealized Fair Unrealized Federal agencies and GSEs $ 83,671 $ 1,737 $ 83,671 $ 1,737 $ — $ — Mortgage-backed and CMOs 60,908 689 59,334 660 1,574 29 State and municipal 14,541 259 13,480 237 1,061 22 Corporate 1,553 5 1,553 5 — — Total $ 160,673 $ 2,690 $ 158,038 $ 2,639 $ 2,635 $ 51 Federal agencies and GSEs: The unrealized losses on the Company's investment in 21 government sponsored entities ("GSE") securities were caused by interest rate increases. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost basis of the investments. Because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost basis, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at June 30, 2017 . Mortgage-backed securities: The unrealized losses on the Company's investment in 38 GSE mortgage-backed securities were caused by interest rate increases. Four of these securities were in an unrealized loss position for 12 months or more. The contractual cash flows of those investments are guaranteed by an agency of the U.S. Government. Accordingly, it is expected that the securities would not be settled at a price less than the amortized cost basis of the Company's investments. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost basis, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at June 30, 2017 . Collateralized Mortgage Obligations: The unrealized losses associated with two private GSE collateralized mortgage obligations ("CMO") were due to normal market fluctuations. One of these securities had been in an unrealized loss position for 12 months or more. The contractual cash flows of those investments are guaranteed by an agency of the U.S. Government. Accordingly, it is expected that the securities would not be settled at a price less than the amortized cost basis of the Company's investments. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost basis, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at June 30, 2017 . State and municipal securities: The unrealized losses on 21 state and municipal securities were caused by interest rate increases. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost basis of the investments. Because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost basis, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at June 30, 2017 . Corporate securities: The unrealized losses on two corporate securities were caused by interest rate increases. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost basis of the investments. Because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost basis, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at June 30, 2017 . Restricted stock: When evaluating restricted stock for impairment, its value is based on the ultimate recoverability of the par value rather than by recognizing temporary declines in value. The Company does not consider restricted stock to be other-than-temporarily impaired at June 30, 2017 , and no impairment has been recognized. The table below shows estimated fair value and gross unrealized losses, aggregated by investment category and length of time that individual securities had been in a continuous unrealized loss position, at December 31, 2016 (dollars in thousands): Total Less than 12 Months 12 Months or More Fair Unrealized Fair Unrealized Fair Unrealized Federal agencies and GSEs $ 89,597 $ 2,387 $ 89,597 $ 2,387 $ — $ — Mortgage-backed and CMOs 57,762 938 56,076 911 1,686 27 State and municipal 47,221 782 47,221 782 — — Corporate 2,895 23 2,895 23 — — Total $ 197,475 $ 4,130 $ 195,789 $ 4,103 $ 1,686 $ 27 Other-Than-Temporary-Impaired Securities As of June 30, 2017 and December 31, 2016 , there were no securities classified as other-than-temporarily impaired.

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

Qualitative factors include trends in delinquencies, nonaccrual loans, and loss rates; trends in volume and terms of loans, effects of changes in risk selection, underwriting standards, and lending policies; experience of lending officers, other lending staff and loan review; national, regional, and local economic trends and conditions; legal, regulatory and collateral factors; and concentrations of credit.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets The Company records as goodwill the excess of the purchase price over the fair value of the identifiable net assets acquired. Impairment testing is performed annually, as well as when an event triggering impairment may have occurred. The Company performs its annual analysis as of June 30 each fiscal year. Accounting guidance permits preliminary assessment of qualitative factors to determine whether more substantial impairment testing is required. The Company chose to bypass the preliminary assessment and utilized a two-step process for impairment testing of goodwill. The first step tests for impairment, while the second step, if necessary, measures the impairment. No indicators of impairment were identified as of June 30, 2017. Core deposit intangibles resulting from the acquisition of MidCarolina Financial Corporation ("MidCarolina") in July 2011 were $6,556,000 and are being amortized on an accelerated basis over 108 months. Core deposit intangibles resulting from the acquisition of MainStreet BankShares, Inc. ("MainStreet") in January 2015 were $1,839,000 and are being amortized on an accelerated basis over 120 months . The changes in the carrying amount of goodwill and intangibles for the six months ended June 30, 2017 , are as follows (dollars in thousands): Goodwill Intangibles Balance at December 31, 2016 $ 43,872 $ 1,719 Additions — — Amortization — (368 ) Impairment — — Balance at June 30, 2017 $ 43,872 $ 1,351

Debt Disclosure [Abstract]
Short-term Borrowings	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 , each, and, additionally, has access to the FRB's discount window.

Long-term Borrowings	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 June 30, 2017 , $467,616,000 in eligible collateral was pledged under the blanket floating lien agreement which covers both short-term and long-term borrowings.

Trust Preferred Capital Notes [Abstract]
Junior Subordinated Debt	Junior Subordinated Debt On April 7, 2006, AMNB Statutory Trust I, a Delaware statutory trust and a wholly owned unconsolidated subsidiary of the Company, issued $ 20,000,000 of preferred securities (the "Trust Preferred Securities") in a private placement pursuant to an applicable exemption from registration. The Trust Preferred Securities mature on June 30, 2036 , but may be redeemed at the Company's option beginning on September 30, 2011. 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 "Junior Subordinated Debt"), issued pursuant to junior subordinated debentures entered into between the Company and Wilmington Trust Company, as trustee. The proceeds of the Junior Subordinated Debt were used to fund the cash portion of the merger consideration to the former shareholders of Community First Financial Corporation in connection with the Company's acquisition of that company in 2006, and for general corporate purposes. On July 1, 2011, in connection with the MidCarolina merger, the Company assumed $8,764,000 in junior subordinated debt to MidCarolina Trust I and MidCarolina Trust II, two separate Delaware statutory trusts (the "MidCarolina Trusts"), to fully and unconditionally guarantee the preferred securities issued by the MidCarolina Trusts. These long-term obligations, which currently qualify as Tier 1 capital, constitute a full and unconditional guarantee by the Company of the MidCarolina Trusts' obligations. The MidCarolina Trusts were 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 as of June 30, 2017 and December 31, 2016 (dollars in thousands): Issuing Entity Date Issued Interest Rate Maturity Date Principal Amount June 30, 2017 December 31, 2016 AMNB Trust I 4/7/2006 Libor plus 1.35% 6/30/2036 $ 20,619 $ 20,619 MidCarolina Trust I 10/29/2002 Libor plus 3.45% 11/7/2032 4,294 4,265 MidCarolina Trust II 12/3/2003 Libor plus 2.95% 10/7/2033 2,862 2,840 $ 27,775 $ 27,724 The principal amounts reflected above for the MidCarolina Trusts are net of fair value adjustments of $1,608,000 and $1,659,000 at June 30, 2017 and December 31, 2016 , respectively. The original fair value adjustments of $1,197,000 and $1,021,000 were recorded as a result of the acquisition of MidCarolina on July 1, 2011, and are being amortized into interest expense over the remaining lives of the respective borrowings.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock Based Compensation	Stock Based Compensation The Company's 2008 Stock Incentive Plan ("2008 Plan") was adopted by the Board of Directors of the Company on February 19, 2008, and approved by shareholders on April 22, 2008, at the Company's 2008 Annual Meeting of Shareholders. The 2008 Plan provides for the granting of restricted stock awards and incentive and non-statutory options to employees and directors on a periodic basis, at the discretion of the Board of Directors or a Board designated committee. The 2008 Plan authorizes the issuance of up to 500,000 shares of common stock. The 2008 Plan replaced the Company's stock option plan that was approved by the shareholders at the 1997 Annual Meeting, which expired 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 six months ended June 30, 2017 is as follows: Option Weighted Weighted Aggregate Outstanding at December 31, 2016 58,411 $ 24.37 Acquired in acquisition — — Granted — — Exercised (3,300 ) 21.97 Forfeited (578 ) 23.33 Expired (1,320 ) 41.67 Outstanding at June 30, 2017 53,213 $ 24.10 1.28 years $ 684 Exercisable at June 30, 2017 53,213 $ 24.10 1.28 years $ 684 The fair value of options is estimated at the date of grant using the Black-Scholes option pricing model and expensed over the options' vesting period. No stock options have been granted since 2009. As of June 30, 2017 , there were no unrecognized compensation expenses related to nonvested stock option grants. Restricted Stock The Company from time-to-time grants shares of restricted stock to key employees and non-employee directors. These awards help align the interests of these employees and directors with the interests of the shareholders of the Company by providing economic value directly related to increases in the value of the Company's common stock. The value of the stock awarded is established as the fair 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. The majority of the restricted stock granted in 2016 and 2017 cliff vests at the end of a 36 month period beginning on the date of the grant. The remainder vests a third each year beginning on the date of the grant. Nonvested restricted stock activity for the six months ended June 30, 2017 is summarized in the following table. Restricted Stock Shares Weighted Average Grant Date Value Nonvested at December 31, 2016 50,822 $ 23.21 Granted 14,453 34.74 Vested (17,126 ) 24.21 Forfeited — — Nonvested at June 30, 2017 48,149 $ 26.32 As of June 30, 2017 and December 31, 2016 , there was $765,000 and $568,000 , respectively, in unrecognized compensation cost related to nonvested restricted stock granted under the 2008 Plan. The weighted average period over which this cost is expected to be recognized is 1.54 years . The share based compensation expense for nonvested restricted stock was $304,000 and $153,000 during the first six months of 2017 and 2016 , respectively . Starting in 2010, the Company began offering its outside directors alternatives with respect to director compensation. The regular quarterly board retainer can be received in the form of either (a) $5,800 in cash or (b) shares of immediately vested, but restricted stock with a market value of $6,250 . Monthly meeting fees can also be received as $725 per meeting in cash or $900 in immediately vested, but restricted stock. For 2017 , all 12 outside directors have elected to receive stock in lieu of cash for either all or part of their monthly retainer board fees. Only outside directors receive board fees. The Company issued 7,109 and 7,451 shares and recognized share based compensation expense of $255,000 and $198,000 during the first six months of 2017 and 2016 , respectively.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments Determination of Fair Value The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. In accordance with the fair value measurements and disclosures topic of FASB ASC 820, the fair value of an instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company's various instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. The fair value guidance provides a consistent definition of fair value, which focuses on exit price in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions. Fair Value Hierarchy In accordance with this guidance, the Company groups its 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 financial liabilities recorded at fair value on a recurring basis in the financial statements: Securities available for sale: Securities available for sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted market prices, when available (Level 1). If quoted market prices are not available, fair values are measured utilizing independent valuation techniques of identical or similar securities for which significant assumptions are derived primarily from or corroborated by observable market data. Third party vendors compile prices from various sources and may determine the fair value of identical or similar securities by using pricing models that consider observable market data (Level 2). If no observable market data is available, valuations are based upon third party model based techniques (Level 3). There were no securities recorded with a Level 3 valuation at June 30, 2017 or December 31, 2016 . The following table presents the balances of financial assets measured at fair value on a recurring basis at the dates indicated (dollars in thousands): Fair Value Measurements at June 30, 2017 Using Balance at June 30, Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Description 2017 Level 1 Level 2 Level 3 Assets: Securities available for sale: Federal agencies and GSEs $ 91,692 $ — $ 91,692 $ — Mortgage-backed and CMOs 79,068 — 79,068 — State and municipal 99,205 — 99,205 — Corporate 8,315 — 8,315 — Equity securities 2,223 — 2,223 — Total $ 280,503 $ — $ 280,503 $ — Fair Value Measurements at December 31, 2016 Using Balance at December 31, Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Description 2016 Level 1 Level 2 Level 3 Assets: Securities available for sale: Federal agencies and GSEs $ 104,054 $ — $ 104,054 $ — Mortgage-backed and CMOs 79,493 — 79,493 — State and municipal 147,515 — 147,515 — Corporate 13,492 — 13,492 — Equity securities 1,948 — 1,498 — Total $ 346,502 $ — $ 346,052 $ — 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 six month period ended June 30, 2017 or the year ended December 31, 2016 . Gains and losses on the sale of loans are recorded within mortgage banking income 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 when due. The measurement of the loss associated with impaired loans can be based on either the observable market price of the loan or the fair value of the collateral. Collateral may be in the form of real estate or business assets including equipment, inventory, and accounts receivable. The vast majority of the Company's collateral is real estate. The value of real estate collateral is determined utilizing a market valuation approach based on an appraisal, of one year or less, conducted by an independent, licensed appraiser using observable market data (Level 2). However, if the collateral is a house or building in the process of construction or if an appraisal of the property is more than one year old and not solely based on observable market comparables or management determines the fair value of the collateral is further impaired below the appraised value, then a Level 3 valuation is considered to measure the fair value. The value of business equipment is based upon an outside appraisal, of one year or less, if deemed significant, or the net book value on the applicable business's financial statements if not considered significant using observable market data. Likewise, values for inventory and accounts receivable 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. OREO: Measurement for fair values for OREO 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 other real estate owned expense, net on the Consolidated Statements of Income. The following table summarizes the Company's assets that were measured at fair value on a nonrecurring basis at the dates indicated (dollars in thousands): Fair Value Measurements at June 30, 2017 Using Balance at June 30, Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Description 2017 Level 1 Level 2 Level 3 Assets: Loans held for sale $ 2,379 $ — $ 2,379 $ — Impaired loans, net of valuation allowance 1,534 — — 1,534 Other real estate owned, net 1,686 — — 1,686 Fair Value Measurements at December 31, 2016 Using Balance at December 31, Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Description 2016 Level 1 Level 2 Level 3 Assets: Loans held for sale $ 5,996 $ — $ 5,996 $ — Impaired loans, net of valuation allowance 2,151 — — 2,151 Other real estate owned, net 1,328 — — 1,328 The following tables summarize the Company's quantitative information about Level 3 fair value measurements at the dates indicated: Quantitative Information About Level 3 Fair Value Measurements at June 30, 2017 Assets Valuation Technique Unobservable Input Weighted Impaired loans Discounted appraised value Selling cost 8 % Other real estate owned, net Discounted appraised value Selling cost 8 % Quantitative Information About Level 3 Fair Value Measurements at December 31, 2016 Assets Valuation Technique Unobservable Input Weighted Impaired loans Discounted appraised value Selling cost 8 % Other real estate owned, net Discounted appraised value Selling cost 6 % ASC 825, "Financial Instruments," requires disclosure about fair value of financial instruments for interim periods and excludes certain financial instruments and all non-financial instruments from its disclosure requirements.

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. 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 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 analysis, 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 analysis or underlying collateral values, where applicable. Bank owned life insurance. Bank owned life insurance represents insurance policies on officers, directors, and past directors of the Company. The cash values of the policies are estimates using information provided by insurance carriers. These policies are carried at their cash surrender value, which approximates the fair value. Accrued interest receivable . The carrying amount is a reasonable estimate of fair value. Deposits . The fair value of demand deposits, savings deposits, and money market deposits equals the carrying value. The fair value of fixed-rate certificates of deposit is estimated by discounting the future cash flows using the current rates at which similar deposit instruments would be offered to depositors for the same remaining maturities. Repurchase agreements . The carrying amount is a reasonable estimate of fair value. Other short-term borrowings. The carrying amount is a reasonable estimate of fair value. Long-term borrowings. The fair values of long-term borrowings are estimated using discounted cash flow analysis based on the interest rates for similar types of borrowing arrangements. Junior subordinated debt . 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 June 30, 2017 and December 31, 2016 , the fair value of off-balance sheet instruments was deemed immaterial, and therefore was not included in the previous table. The Company assumes interest rate risk (the risk that interest rates will change) in its normal operations. As a result, the fair values of the Company's financial instruments will change when interest rates change and that change may be either favorable or unfavorable to the Company.

Accounting Policies (Policies)

Accounting Policies (Policies)	6 Months Ended

Accounting Policies [Abstract]
Basis of Accounting	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 consolidated 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, unfunded pension liability, other-than-temporary impairment of securities, accounting for merger and acquisition activity, accounting for acquired loans with specific credit-related deterioration, the valuation of deferred tax assets and liabilities, and the valuation of other real estate owned ("OREO"). 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 8. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments (consisting of normal recurring accruals) necessary to present fairly the results of the interim periods. The results of operations for the interim periods are not necessarily indicative of the results that may occur for any other period. Certain reclassifications have been made to prior period balances to conform to the current period presentation. These reclassifications did not have an impact on net income and were considered immaterial. These statements should be read in conjunction with the Notes to Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2016 .
Adoption of New Accounting Standard and Recent Accounting Pronouncements	Adoption of New Accounting Standard During the first quarter of 2017, the Company adopted Accounting Standards Update ("ASU") 2016-09, "Compensation-Stock Compensation (Topic 718): Improvements to Employer Share- Based Payment Accounting." This ASU simplifies several aspects of the accounting for share-based payment award transactions, one of which is the recognition of excess tax benefits and deficiencies related to share-based payments, including tax benefits of dividends on share-based payment awards. Prior to the adoption of ASU 2016-09, such tax consequences were recognized as components of additional paid-in capital. With the adoption of this ASU, tax benefits and deficiencies are recognized within income tax expense. In accordance with the adoption provisions of ASU 2016-09, the results for the second quarter and first six months of 2016 include only the excess tax (expense) benefits attributable to the second quarter and first six months of 2016 in the amount of $2,000 and $50,000 , respectively. Recent Accounting Pronouncements In January 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." The amendments in ASU 2016-01, among other things: (1) requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; (2) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; (3) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables); and (4) eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently assessing the impact that ASU 2016-01 will have on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)." Among other things, in the amendments in ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee's right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company is currently assessing the impact that ASU 2016-02 will have on its consolidated financial statements. During June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." The amendments in this ASU, among other things, require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The amendments in this ASU are effective for Securities and Exchange Commission ("SEC") filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The Company is currently assessing the impact that ASU 2016-13 will have on its consolidated financial statements. During August 2016, the FASB issued ASU No. 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments", to address diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The amendments should be applied using a retrospective transition method to each period presented. If retrospective application is impractical for some of the issues addressed by the update, the amendments for those issues would be applied prospectively as of the earliest date practicable. Early adoption is permitted, including adoption in an interim period. The Company does not expect the adoption of ASU 2016-15 to have a material impact on its consolidated financial statements. During January 2017, the FASB issued ASU No. 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business". The amendments in this ASU clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. Under the current implementation guidance in Topic 805, there are three elements of a business-inputs, processes, and outputs. While an integrated set of assets and activities (collectively referred to as a "set") that is a business usually has outputs, outputs are not required to be present. In addition, all the inputs and processes that a seller uses in operating a set are not required if market participants can acquire the set and continue to produce outputs. The amendments in this ASU provide a screen to determine when a set is not a business. If the screen is not met, the amendments (1) require that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output and (2) remove the evaluation of whether a market participant could replace missing elements. The ASU provides a framework to assist entities in evaluating whether both an input and a substantive process are present. The amendments in this ASU are effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The amendments in this ASU should be applied prospectively on or after the effective date. No disclosures are required at transition. The Company does not expect the adoption of ASU 2017-01 to have a material impact on its consolidated financial statements. During January 2017, the FASB issued ASU No. 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment". The amendments in this ASU simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit's goodwill with the carrying amount of that goodwill. Instead, under the amendments in this ASU, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. Public business entities that are SEC filers should adopt the amendments in this ASU for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company does not expect the adoption of ASU 2017-04 to have a material impact on its consolidated financial statements. During March 2017, the FASB issued ASU 2017-07, "Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost." The amendments in this ASU require an employer that offers defined benefit pension plans, other postretirement benefit plans, or other types of benefits accounted for under Topic 715 to report the service cost component of net periodic benefit cost in the same line item(s) as other compensation costs arising from services rendered during the period. The other components of net periodic benefit cost are required to be presented in the income statement separately from the service cost component. If the other components of net periodic benefit cost are not presented on a separate line or lines, the line item(s) used in the income statement must be disclosed. In addition, only the service cost component will be eligible for capitalization as part of an asset, when applicable. The amendments are effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption is permitted. The Company does not expect the adoption of ASU 2017-07 to have a material impact on its consolidated financial statements. During March 2017, the FASB issued ASU 2017-08, "Receivables-Nonrefundable Fees and Other Costs (Subtopic 310‐20), Premium Amortization on Purchased Callable Debt Securities." The amendments in this ASU shorten the amortization period for certain callable debt securities purchased at a premium. Upon adoption of the standard, premiums on these qualifying callable debt securities will be amortized to the earliest call date. Discounts on purchased debt securities will continue to be accreted to maturity. The amendments are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. Upon transition, entities should apply the guidance on a modified retrospective basis, with a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption and provide the disclosures required for a change in accounting principle. The Company is currently assessing the impact that ASU 2017-08 will have on its consolidated financial statements. During May 2017, the FASB issued ASU 2017-09, "Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting." The amendments provide guidance on determining which changes to the terms and conditions of share-based payment awards require an entity to apply modification accounting under Topic 718. The amendments are effective for all entities for annual periods, including interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period, for reporting periods for which financial statements have not yet been issued. The Company is currently assessing the impact that ASU 2017-09 will have on its consolidated financial statements.
