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, other-than-temporary impairment of securities, accounting for merger and acquisition activity, accounting for acquired loans with specific credit-related deterioration, and the valuation of deferred tax assets and liabilities. 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 11. 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, 2018 . Adoption of New Accounting Standards On January 1, 2019, the Company adopted Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)." Among other things, in the amendments in ASU 2016-02, lessees are required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (i) a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and (ii) 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. 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 Financial Accounting Standards Board ("FASB") made subsequent amendments to Topic 842 in July 2018 through ASU 2018-10 ("Codification Improvements to Topic 842, Leases.") and ASU 2018-11 ("Leases (Topic 842): Targeted Improvements."). Among these amendments is the provision in ASU 2018-11 that provides entities with an additional (and optional) transition method to adopt the new leases standard. Under this new transition method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, an entity's reporting for the comparative periods presented in the financial statements in which it adopts the new leases standard continue to be in accordance with current GAAP (Topic 840, Leases). The Company adopted using the additional (and optional) transition method. The effect of adopting this standard on January 1, 2019 was an approximately $4.4 million increase in assets and liabilities on the Company's consolidated balance sheet. Recent Accounting Pronouncements In June 2016, the FASB issued ASU 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. At the FASB’s October 16, 2019 meeting, the board amended the effective date of this ASU for many companies. Public business entities that are Securities and Exchange Commission ("SEC") filers, excluding those meeting the smaller reporting company definition, will retain the initial required implementation date of fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. All other entities will be required to apply the guidance for fiscal years, and interim periods within those years, beginning after December 15, 2022 . As a smaller reporting company, the Company has elected to defer adoption until January, 2023. The Company will continue to validate its models that will be used upon future adoption of the standard. The implementation of this ASU will likely result in increases to the Company's reserves when implemented. In January 2017, the FASB issued ASU 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. In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement." The amendments in this ASU modify the disclosure requirements in Topic 820 to add disclosures regarding changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty. Certain disclosure requirements in Topic 820 are also removed or modified. The amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Certain of the amendments are to be applied prospectively while others are to be applied retrospectively. Early adoption is permitted. The Company does not expect the adoption of ASU 2018-13 to have a material impact on its consolidated financial statements. In August 2018, the FASB issued ASU 2018-14, "Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20): Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans." The amendments in this ASU modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. Certain disclosure requirements have been deleted while the following disclosure requirements have been added: the weighted-average interest crediting rates for cash balance plans and other plans with promised interest crediting rates and an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. The amendments also clarify the disclosure requirements in paragraph 715-20-50-3, which state that the following information for defined benefit pension plans should be disclosed: the projected benefit obligation ("PBO") and fair value of plan assets for plans with PBOs in excess of plan assets and the accumulated benefit obligation ("ABO") and fair value of plan assets for plans with ABOs in excess of plan assets. The amendments are effective for fiscal years ending after December 15, 2020. Early adoption is permitted. The Company is currently assessing the impact that ASU 2018-14 will have on its consolidated financial statements. In April 2019, the FASB issued ASU 2019-04, "Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments." The amendments in this ASU clarify and improve areas of guidance related to the recently issued standards on credit losses, hedging, and recognition and measurement including improvements resulting from various Transition Resource Group meetings. The amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the impact that ASU 2019-04 will have on its consolidated financial statements. In May 2019, the FASB issued ASU 2019-05, "Financial Instruments-Credit Losses (Topic 326): Targeted Transition Relief." The amendments in this ASU provide entities that have certain instruments within the scope of Subtopic 326-20 with an option to irrevocably elect the fair value option in Subtopic 825-10, applied on an instrument-by-instrument basis for eligible instruments, upon the adoption of Topic 326. The fair value option election does not apply to held-to-maturity debt securities. An entity that elects the fair value option should subsequently measure those instruments at fair value with changes in fair value flowing through earnings. The amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The amendments should be applied on a modified-retrospective basis by means of a cumulative-effect adjustment to the opening balance of retained earnings balance in the balance sheet. Early adoption is permitted. The Company is currently assessing the impact that ASU 2019-05 will have on its consolidated financial statements.

Business Combinations [Abstract]
Acquisitions	Acquisitions On April 1, 2019, the Company completed its acquisition of Roanoke-based HomeTown Bankshares Corporation ("HomeTown") and its wholly-owned subsidiary bank, HomeTown Bank. Pursuant and subject to the terms of the merger agreement, as a result of the merger, the holders of shares of HomeTown common stock received 0.4150 shares of the Company's common stock for each share of HomeTown common stock held immediately prior to the effective date of 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, in accordance with Accounting Standards Codification ("ASC") 350, Intangibles-Goodwill and Other. The following table provides a preliminary assessment of the consideration transferred, assets acquired, and liabilities assumed as of the date of the acquisition (dollars in thousands): Consideration Paid: Common shares issued (2,361,686) $ 82,470 Issuance of replacement stock options/restricted stock 753 Cash paid in lieu of fractional shares 27 Value of consideration 83,250 Assets acquired: Cash and cash equivalents 26,283 Investment securities 34,876 Restricted stock 2,588 Loans 444,324 Premises and equipment 12,554 Deferred income taxes 2,329 Core deposit intangible 8,200 Other real estate owned 1,442 Banked owned life insurance 8,246 Other assets 14,244 Total assets 555,086 Liabilities assumed: Deposits 483,626 Short-term FHLB advances 14,883 Long-term FHLB advances 778 Subordinated debt 7,530 Other liabilities 5,780 Total liabilities 512,597 Net assets acquired 42,489 Goodwill resulting from merger with HomeTown $ 40,761 The acquired loans were recorded at fair value at the acquisition date without carryover of HomeTown's previously established allowance for loan losses. The fair value of the loans was determined using market participant assumptions in estimating the amount and timing of both principal and interest cash flows expected to be collected on the loans and leases and then applying a market-based discount rate to those cash flows. In this regard, the acquired loans were segregated into pools based on loan type and credit risk. Loan type was determined based on collateral type, purpose, and lien position. Credit risk characteristics included risk rating groups (pass rated loans and adversely classified loans), and past due status. For valuation purposes, these pools were further disaggregated by maturity, pricing characteristics (e.g., fixed-rate, adjustable-rate) and re-payment structure (e.g., interest only, fully amortizing, balloon). If new information is obtained about facts and circumstances about expected cash flows that existed as of the acquisition date, management will adjust fair values in accordance with accounting for business combinations. 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 these criteria, which are accounted for under ASC 310-20, Receivables - Nonrefundable Fees and Other Costs, (acquired performing). The following table presents the acquired impaired loans receivable at the acquisition date (dollars in thousands): Contractually required principal and interest at acquisition $ 45,551 Contractual cash flows not expected to be collected (nonaccretable difference) 8,296 Expected cash flows at acquisition 37,255 Interest component of expected cash flows (accretable yield) 4,410 Fair value of acquired loans accounted for under FASB ASC 310-30 $ 32,845 Direct costs related to the acquisition were expensed as incurred. During the nine months ended September 30, 2019 , the Company incurred $11.3 million in merger and acquisition integration expenses related to the merger, including $9.1 million in data processing termination and conversion costs, $1.7 million in legal and professional fees, $0.4 million in salary related expense, and $0.1 million in other noninterest expenses. The majority of these expenses were related to integration and are deductible for tax purposes. The following tables present unaudited pro forma information as if the acquisition of HomeTown had occurred on January 1, 2018. These results combine the historical results of HomeTown in the Company's Consolidated Statements 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, 2018. In particular, no adjustments have been made to eliminate the amount of HomeTown's provision for credit losses that would not have been necessary had the acquired loans been recorded at fair value as of January 1, 2018. Pro forma adjustments below include the net impact of accretion for 2018 and the elimination of merger-related costs for 2019. The Company expects to achieve further operating cost savings and other business synergies as a result of the acquisition which are not reflected in the pro forma amounts below (dollars in thousands, except per share data): Pro forma September 30, 2019 September 30, 2018 Total revenues (1) $ 24,636 $ 24,478 Net income 8,608 7,458 Earnings per share 0.77 0.67 (1) Includes net interest income and noninterest income.

Investments, Debt and Equity Securities [Abstract]
Securities	Securities The amortized cost and fair value of investments in debt securities at September 30, 2019 were as follows (dollars in thousands): September 30, 2019 Amortized Unrealized Unrealized Securities available for sale: Federal agencies and GSEs $ 119,682 $ 1,837 $ 263 $ 121,256 Mortgage-backed and CMOs 133,533 1,875 207 135,201 State and municipal 43,012 871 28 43,855 Corporate 8,015 163 — 8,178 Total securities available for sale $ 304,242 $ 4,746 $ 498 $ 308,490 The Company adopted ASU 2016-01 effective January 1, 2018. The Company recognized in income a $333,000 change in the fair value of equity securities during the nine months of 2019 . During the nine months ended September 30, 2019 , the Company sold $445,000 in equity securities at fair value and had no remaining equity securities at September 30, 2019 . The Company had equity securities with a fair value of $2,087,000 at September 30, 2018 and recognized in income a $312,000 change in the fair value of equity securities during the nine months of 2018 . During the 2018 period, the Company sold $431,000 in equity securities at fair value. The amortized cost and fair value of investments in debt securities at December 31, 2018 were as follows (dollars in thousands): December 31, 2018 Amortized Unrealized Unrealized Securities available for sale: Federal agencies and GSEs $ 137,070 $ 442 $ 3,473 $ 134,039 Mortgage-backed and CMOs 113,883 385 2,401 111,867 State and municipal 80,022 411 531 79,902 Corporate 6,799 68 22 6,845 Total securities available for sale $ 337,774 $ 1,306 $ 6,427 $ 332,653 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 sheets. The FRB requires the Bank to maintain stock with a par value equal to 3.00% of its outstanding capital and an additional 3.00% is on call. The FHLB requires the Bank to maintain stock in an amount equal to 4.25% of outstanding borrowings and a specific percentage of the Bank's total assets. The cost of restricted stock at September 30, 2019 and December 31, 2018 was as follows (dollars in thousands): September 30, 2019 December 31, 2018 FRB stock $ 6,406 $ 3,621 FHLB stock 2,215 1,626 Total restricted stock $ 8,621 $ 5,247 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 September 30, 2019 . 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, at September 30, 2019 , 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 $ 59,141 $ 263 $ 1,889 $ 30 $ 57,252 $ 233 Mortgage-backed and CMOs 32,617 207 7,468 12 25,149 195 State and municipal 4,579 28 3,428 19 1,151 9 Total $ 96,337 $ 498 $ 12,785 $ 61 $ 83,552 $ 437 Federal agencies and GSEs: The unrealized losses on the Company's investment in 25 government sponsored entities ("GSE") securities were caused by interest rate increases. Twelve of these securities were in an unrealized loss position for 12 months or more. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost basis of the investments. Because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost basis, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at September 30, 2019 . Mortgage-backed securities: The unrealized losses on the Company's investment in 24 GSE mortgage-backed securities were caused by interest rate increases. Seventeen 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 September 30, 2019 . Collateralized Mortgage Obligations: The unrealized losses associated with four private GSE collateralized mortgage obligations ("CMOs") were due to normal market fluctuations. One of these securities was in an unrealized loss position for 12 months or more. The contractual cash flows of that investment is guaranteed by an agency of the U.S. Government. Accordingly, it is expected that the security would not be settled at a price less than the amortized cost basis of the Company's investment. 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 investment and it is not more likely than not that the Company will be required to sell the investment before recovery of its amortized cost basis, which may be maturity, the Company does not consider the investment to be other-than-temporarily impaired at September 30, 2019 . State and municipal securities: The unrealized losses on seven state and municipal securities were caused by interest rate increases. Two of these securities were in an unrealized loss position for 12 months or more. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost basis of the investments. Because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost basis, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at September 30, 2019 . Corporate securities: There were no corporate bonds in an unrealized loss position at September 30, 2019 . 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 September 30, 2019 , 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, 2018 (dollars in thousands): Total Less than 12 Months 12 Months or More Fair Unrealized Fair Unrealized Fair Unrealized Federal agencies and GSEs $ 103,797 $ 3,473 $ 14,982 $ 8 $ 88,815 $ 3,465 Mortgage-backed and CMOs 86,852 2,401 5,473 15 81,379 2,386 State and municipal 39,755 531 7,199 18 32,556 513 Corporate 484 22 — — 484 22 Total $ 230,888 $ 6,427 $ 27,654 $ 41 $ 203,234 $ 6,386 Other-Than-Temporarily-Impaired Securities As of September 30, 2019 and December 31, 2018 , there were no securities classified as other-than-temporarily impaired. Realized Gains and Losses The following table presents the gross realized gains and losses on and the proceeds from the sale of securities available for sale during the three and nine months ended September 30, 2019 and 2018 (dollars in thousands): Three Months Ended September 30, 2019 Nine Months Ended September 30, 2019 Realized gains (losses): Gross realized gains $ — $ 194 Gross realized losses — (54 ) Net realized gains $ — $ 140 Proceeds from sales of securities $ — $ 29,878 Three Months Ended September 30, 2018 Nine Months Ended September 30, 2018 Realized gains (losses): Gross realized gains $ 237 $ 342 Gross realized losses (164 ) (261 ) Net realized gains $ 73 $ 81 Proceeds from sales of securities $ 35,541 $ 57,607

There were no loans modified as troubled debt restructurings ("TDRs") during the three months ended September 30, 2019 and 2018 . During each of the nine months ended September 30, 2019 and 2018 , there was one residential real estate loan modified as a TDR. These were included in the impaired loan balances and were extensions of the loan maturity with a pre- and post-modification outstanding recorded investment of $207,000 for 2019 and $11,000 for 2018 . During the three and nine months ended September 30, 2019 and 2018 , the Company had no loans that subsequently defaulted within 12 months of modification. The Company defines defaults as one or more payments that occur more than 90 days past the due date, charge-off or foreclosure subsequent to modification.

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.

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, 2019. 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. in January 2015 were $1,839,000 and are being amortized on an accelerated basis over 120 months . Core deposit intangibles resulting from the acquisition of HomeTown in April 2019 were $8,200,000 and are being amortized on an accelerated basis over 120 months .

Leases [Abstract]
Leases	Leases On January 1, 2019, the Company adopted ASU No. 2016-02 "Leases (Topic 842)" and all subsequent ASUs that modified Topic 842. The Company elected the prospective application approach provided by ASU 2018-11 and did not adjust prior periods for ASC 842. The Company also elected certain practical expedients within the standard and, consistent with such elections, did not reassess whether any expired or existing contracts are or contain leases, did not reassess the lease classification for any expired or existing leases, and did not reassess any initial direct costs for existing leases. As stated in the Company's 2018 Form 10-K, the implementation of the new standard resulted in recognition of a right-of-use asset and lease liability of $4.4 million at the date of adoption, which is related to the Company's lease of premises used in operations. In connection with the HomeTown merger, the Company added $1.8 million to the right-of-use asset and lease liability. The right-of-use asset and lease liability are included in other assets and other liabilities, respectively, in the Company's consolidated balance sheets. Lease liabilities represent the Company's obligation to make lease payments and are presented at each reporting date as the net present value of the remaining contractual cash flows. Cash flows are discounted at the Company's incremental borrowing rate in effect at the commencement date of the lease. Right-of-use assets represent the Company's right to use the underlying asset for the lease term and are calculated as the sum of the lease liability and if applicable, prepaid rent, initial direct costs and any incentives received from the lessor. The Company's long-term lease agreements are classified as operating leases. Certain of these leases offer the option to extend the lease term and the Company has included such extensions in its calculation of the lease liabilities to the extent the options are reasonably assured of being exercised. The lease agreements do not provide for residual value guarantees and have no restrictions or covenants that would impact dividends or require incurring additional financial obligations. The following tables present information about the Company's leases, as of and for the three and nine months ended September 30, 2019 (dollars in thousands): September 30, 2019 Lease liabilities $ 5,542 Right-of-use assets $ 5,520 Weighted average remaining lease term 8.33 years Weighted average discount rate 3.21 % Three Months Ended September 30, 2019 Lease cost Operating lease cost $ 283 Short-term lease cost 1 Total lease cost 284 Cash paid for amounts included in the measurement of lease liabilities $ 274 Nine Months Ended September 30, 2019 Lease cost Operating lease cost $ 777 Short-term lease cost 2 Total lease cost 779 Cash paid for amounts included in the measurement of lease liabilities $ 757 A maturity analysis of operating lease liabilities and reconciliation of the undiscounted cash flows to the total of operating lease liabilities is as follows (dollars in thousands): Lease payments due As of September 30, 2019 Three months ending December 31, 2019 $ 256 Twelve months ending December 31, 2020 950 Twelve months ending December 31, 2021 934 Twelve months ending December 31, 2022 912 Twelve months ending December 31, 2023 809 Twelve months ending December 31, 2024 491 Thereafter 2,022 Total undiscounted cash flows $ 6,374 Discount (832 ) Lease liabilities $ 5,542

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 September 30, 2019 and December 31, 2018 (dollars in thousands): Issuing Entity Date Issued Interest Rate Maturity Date Principal Amount September 30, 2019 December 31, 2018 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 4,419 4,377 MidCarolina Trust II 12/3/2003 Libor plus 2.95% 10/7/2033 2,965 2,931 $ 28,003 $ 27,927 The principal amounts reflected above for the MidCarolina Trusts are net of fair value adjustments of $1,380,000 and $1,456,000 at September 30, 2019 and December 31, 2018 , 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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments and Hedging Activities	Derivative Financial Instruments and Hedging Activities The Company uses derivative financial instruments ("derivatives") primarily to manage risks to the Company associated with changing interest rates. The Company's derivatives are hedging instruments in a qualifying hedge accounting relationship (cash flow or fair value hedge). The Company designates derivatives as cash flow hedges when they are used to manage exposure to variability in cash flows on variable rate borrowings such as the Company's trust preferred capital notes. The Company uses interest rate swap agreements as part of its hedging strategy by exchanging variable-rate interest payments on a notional amount equal to the principal amount of the borrowings for fixed-rate interest payments, with such interest rates set based on benchmarked interest rates. All interest rate swaps were entered into with counterparties that met the Company's credit standards and the agreements contain collateral provisions protecting the at-risk party. The Company believes that the credit risk inherent in these derivative contracts is not significant. Terms and conditions of the interest rate swaps vary and amounts receivable or payable are recognized as accrued under the terms of the agreements. The Company assesses the effectiveness of each hedging relationship on a periodic basis. In accordance with ASC 815, Derivatives and Hedging, the effective portions of the derivatives' unrealized gains or losses are recorded as a component of other comprehensive income. Based on the Company's assessment, its cash flow hedges are highly effective, but to the extent that any ineffectiveness exists in the hedge relationships, the amounts would be recorded in interest income and interest expense in the Company's consolidated statements of income. The following tables present information on the Company's derivative financial instruments as of September 30, 2019 and December 31, 2018 (dollars in thousands): September 30, 2019 Notional Amount Positions Assets Liabilities Cash Collateral Pledged Cash flow hedges: Interest rate swaps: Variable-rate to fixed-rate swaps with counterparty $ 28,500 3 $ — $ 3,477 $ 3,950 December 31, 2018 Notional Amount Positions Assets Liabilities Cash Collateral Pledged Cash flow hedges: Interest rate swaps: Variable-rate to fixed-rate swaps with counterparty $ 28,500 3 $ — $ 804 $ 650

Share-based Payment Arrangement [Abstract]
Stock Based Compensation	Stock Based Compensation The Company's 2018 Equity Compensation Plan (the "2018 Plan") was adopted by the Board of Directors of the Company on February 20, 2018, and approved by shareholders on May 15, 2018, at the Company's 2018 Annual Meeting of Shareholders. The 2018 Plan provides for the granting of restricted stock awards, incentive and non-statutory options, and other equity-based awards to employees and directors at the discretion of the Compensation Committee of the Board of Directors. The 2018 Plan authorizes the issuance of up to 675,000 shares of common stock. The 2018 Plan replaced the Company's stock incentive plan that was approved by the shareholders at the 2008 Annual Meeting that expired in February 2018 (the "2008 Plan"). Stock Options Accounting guidance requires that compensation cost relating to share-based payment transactions be recognized in the financial statements with measurement based upon the fair value of the equity or liability instruments issued. A summary of stock option transactions for the nine months ended September 30, 2019 is as follows: Option Weighted Weighted Aggregate Outstanding at December 31, 2018 13,200 $ 21.97 Issued in HomeTown acquisition 40,753 16.63 Granted — — Exercised (32,356 ) 18.81 Forfeited (2,075 ) 16.63 Expired (830 ) 16.63 Outstanding at September 30, 2019 18,692 $ 16.63 5.22 years $ 352 Exercisable at September 30, 2019 14,276 $ 16.63 5.22 years $ 269 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. Replacement stock option awards representing 40,753 shares of the Company's common stock were issued in conjunction with the HomeTown acquisition. As of September 30, 2019 , 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 Company's common 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 cliff vests at the end of a 36 -month period beginning on the date of the grant. The remainder vests one-third each year beginning on the date of the grant. Nonvested restricted stock activity for the nine months ended September 30, 2019 is summarized in the following table.

Fair Value Disclosures [Abstract]
Fair Value Measurements	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 ASC 820, Fair Value Measurement, fair value is the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants 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 the principal or most advantageous market for the asset or liability 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 and equity securities: 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 September 30, 2019 or December 31, 2018 . Derivative asset (liability) - cash flow hedges: Cash flow hedges are recorded at fair value on a recurring basis. Cash flow hedges are valued by a third party using significant assumptions that are observable in the market and can be corroborated by market data. All of the Company's cash flow hedges are classified as Level 2. The following table presents the balances of financial assets and liabilities measured at fair value on a recurring basis at the dates indicated (dollars in thousands): Fair Value Measurements at September 30, 2019 Using Balance at September 30, Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Description 2019 Level 1 Level 2 Level 3 Assets: Securities available for sale: Federal agencies and GSEs $ 121,256 $ — $ 121,256 $ — Mortgage-backed and CMOs 135,201 — 135,201 — State and municipal 43,855 — 43,855 — Corporate 8,178 — 8,178 — Total securities available for sale $ 308,490 $ — $ 308,490 $ — Liabilities: Derivative - cash flow hedges $ 3,477 $ — $ 3,477 $ — Fair Value Measurements at December 31, 2018 Using Balance at December 31, Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Description 2018 Level 1 Level 2 Level 3 Assets: Securities available for sale: Federal agencies and GSEs $ 134,039 $ — $ 134,039 $ — Mortgage-backed and CMOs 111,867 — 111,867 — State and municipal 79,902 — 79,902 — Corporate 6,845 — 6,845 — Total securities available for sale $ 332,653 $ — $ 332,653 $ — Equity securities $ 1,830 $ — $ 1,830 $ — Liabilities: Derivative - cash flow hedges $ 804 $ — $ 804 $ — 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 nine month period ended September 30, 2019 or the year ended December 31, 2018 . 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, the present value of projected cash flows 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). The present value of projected cash flows method results in a Level 3 categorization because the calculation relies on the Company's judgment to determine projected cash flows, which are then discounted at the current rate of the loan, or the rate prior to modification if the loan is a TDR. 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. Other real estate owned: 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 OREO with the associated expense included in OREO 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 September 30, 2019 Using Balance at September 30, Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Description 2019 Level 1 Level 2 Level 3 Assets: Impaired loans, net of valuation allowance 237 — — 237 Other real estate owned, net 1,353 — — 1,353 Fair Value Measurements at December 31, 2018 Using Balance at December 31, Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Description 2018 Level 1 Level 2 Level 3 Assets: Impaired loans, net of valuation allowance 171 — — 171 Other real estate owned, net 869 — — 869 Quantitative Information About Level 3 Fair Value Measurements as of September 30, 2019 and December 31, 2018 : Assets Valuation Technique Unobservable Input Impaired loans Discounted appraised value Selling cost 8.00% Discounted cash flow analysis Market rate for borrower (discount rate) 3.25% - 9.80% Other real estate owned, net Discounted appraised value Selling cost 8.00% ASC 825, Financial Instruments, requires disclosure about fair value of financial instruments, including those financial assets and financial liabilities that are not required to be measured and reported at fair value on a recurring or nonrecurring basis.

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, other-than-temporary impairment of securities, accounting for merger and acquisition activity, accounting for acquired loans with specific credit-related deterioration, and the valuation of deferred tax assets and liabilities. 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 11. 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.
Adoption of New Accounting Standards and Recent Accounting Pronouncements	Adoption of New Accounting Standards On January 1, 2019, the Company adopted Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)." Among other things, in the amendments in ASU 2016-02, lessees are required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (i) a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and (ii) 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. 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 Financial Accounting Standards Board ("FASB") made subsequent amendments to Topic 842 in July 2018 through ASU 2018-10 ("Codification Improvements to Topic 842, Leases.") and ASU 2018-11 ("Leases (Topic 842): Targeted Improvements."). Among these amendments is the provision in ASU 2018-11 that provides entities with an additional (and optional) transition method to adopt the new leases standard. Under this new transition method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, an entity's reporting for the comparative periods presented in the financial statements in which it adopts the new leases standard continue to be in accordance with current GAAP (Topic 840, Leases). The Company adopted using the additional (and optional) transition method. The effect of adopting this standard on January 1, 2019 was an approximately $4.4 million increase in assets and liabilities on the Company's consolidated balance sheet. Recent Accounting Pronouncements In June 2016, the FASB issued ASU 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. At the FASB’s October 16, 2019 meeting, the board amended the effective date of this ASU for many companies. Public business entities that are Securities and Exchange Commission ("SEC") filers, excluding those meeting the smaller reporting company definition, will retain the initial required implementation date of fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. All other entities will be required to apply the guidance for fiscal years, and interim periods within those years, beginning after December 15, 2022 . As a smaller reporting company, the Company has elected to defer adoption until January, 2023. The Company will continue to validate its models that will be used upon future adoption of the standard. The implementation of this ASU will likely result in increases to the Company's reserves when implemented. In January 2017, the FASB issued ASU 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. In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement." The amendments in this ASU modify the disclosure requirements in Topic 820 to add disclosures regarding changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty. Certain disclosure requirements in Topic 820 are also removed or modified. The amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Certain of the amendments are to be applied prospectively while others are to be applied retrospectively. Early adoption is permitted. The Company does not expect the adoption of ASU 2018-13 to have a material impact on its consolidated financial statements. In August 2018, the FASB issued ASU 2018-14, "Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20): Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans." The amendments in this ASU modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. Certain disclosure requirements have been deleted while the following disclosure requirements have been added: the weighted-average interest crediting rates for cash balance plans and other plans with promised interest crediting rates and an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. The amendments also clarify the disclosure requirements in paragraph 715-20-50-3, which state that the following information for defined benefit pension plans should be disclosed: the projected benefit obligation ("PBO") and fair value of plan assets for plans with PBOs in excess of plan assets and the accumulated benefit obligation ("ABO") and fair value of plan assets for plans with ABOs in excess of plan assets. The amendments are effective for fiscal years ending after December 15, 2020. Early adoption is permitted. The Company is currently assessing the impact that ASU 2018-14 will have on its consolidated financial statements. In April 2019, the FASB issued ASU 2019-04, "Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments." The amendments in this ASU clarify and improve areas of guidance related to the recently issued standards on credit losses, hedging, and recognition and measurement including improvements resulting from various Transition Resource Group meetings. The amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the impact that ASU 2019-04 will have on its consolidated financial statements. In May 2019, the FASB issued ASU 2019-05, "Financial Instruments-Credit Losses (Topic 326): Targeted Transition Relief." The amendments in this ASU provide entities that have certain instruments within the scope of Subtopic 326-20 with an option to irrevocably elect the fair value option in Subtopic 825-10, applied on an instrument-by-instrument basis for eligible instruments, upon the adoption of Topic 326. The fair value option election does not apply to held-to-maturity debt securities. An entity that elects the fair value option should subsequently measure those instruments at fair value with changes in fair value flowing through earnings. The amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The amendments should be applied on a modified-retrospective basis by means of a cumulative-effect adjustment to the opening balance of retained earnings balance in the balance sheet. Early adoption is permitted. The Company is currently assessing the impact that ASU 2019-05 will have on its consolidated financial statements.
Derivatives Instruments and Hedging	The Company uses derivative financial instruments ("derivatives") primarily to manage risks to the Company associated with changing interest rates. The Company's derivatives are hedging instruments in a qualifying hedge accounting relationship (cash flow or fair value hedge). The Company designates derivatives as cash flow hedges when they are used to manage exposure to variability in cash flows on variable rate borrowings such as the Company's trust preferred capital notes. The Company uses interest rate swap agreements as part of its hedging strategy by exchanging variable-rate interest payments on a notional amount equal to the principal amount of the borrowings for fixed-rate interest payments, with such interest rates set based on benchmarked interest rates. All interest rate swaps were entered into with counterparties that met the Company's credit standards and the agreements contain collateral provisions protecting the at-risk party. The Company believes that the credit risk inherent in these derivative contracts is not significant. Terms and conditions of the interest rate swaps vary and amounts receivable or payable are recognized as accrued under the terms of the agreements. The Company assesses the effectiveness of each hedging relationship on a periodic basis. In accordance with ASC 815, Derivatives and Hedging, the effective portions of the derivatives' unrealized gains or losses are recorded as a component of other comprehensive income. Based on the Company's assessment, its cash flow hedges are highly effective, but to the extent that any ineffectiveness exists in the hedge relationships, the amounts would be recorded in interest income and interest expense in the Company's consolidated statements of income.
