Significant Accounting Policies [Text Block]	Note 1: General and Summary of Significant Accounting Policies The consolidated financial statements of National Bankshares, Inc. (“NBI”) and its wholly-owned subsidiaries, The National Bank of Blacksburg (the “Bank” or “NBB”) and National Bankshares Financial Services, Inc. (“NBFS”) (collectively, the “Company”), conform to accounting principles generally accepted in the United States of America (“GAAP”) and to general practices within the banking industry. All significant intercompany accounts and transactions between the Company and its subsidiaries have been eliminated. The accompanying interim period consolidated financial statements are unaudited; however, in the opinion of the Company’s management, all adjustments consisting of normal recurring adjustments, which are necessary for a fair presentation of the consolidated financial statements, have been included. Application of the principles of GAAP and practices within the banking industry requires management to make estimates, assumptions, and judgements that affect the amounts reported in the financial statements and accompanying notes. These estimates, assumptions, and judgements are based on information available as of the date of the financial statement; accordingly, as this information changes, the financial statements may reflect different estimates, assumptions, and judgments. Certain policies inherently rely more extensively on the use of estimates, assumptions, and judgments and as such may have a greater possibility of producing results that could be materially different than originally reported. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance of credit losses on loans. The results of operations for the three month period ended March 31, 2024 are not necessarily indicative of results of operations for the full year or any other interim period. The interim period consolidated financial statements and financial information included in this Form 10-Q 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, 2023 (“2023 Form 10-K”). The Company’s significant accounting policies followed in preparation of the unaudited consolidated financial statements are disclosed in Note 1 of the 2023 Form 10-K. There have been no significant changes to the application of significant accounting policies since December 31, 2023. All amounts and disclosures included in this quarterly report as of December 31, 2023, were derived from the Company’s audited consolidated financial statements. The Company posts all reports required to be filed under the Securities Exchange Act of 1934 on its web site at www.nationalbankshares.com. Certain items in the prior period financial statements have been reclassified to conform to the current presentation. These reclassifications had no effect on prior year net income or stockholders’ equity. Risks and Uncertainties The Company is closely monitoring risks that may impact its business, including high inflation, along with U.S. monetary policy maneuvers to reduce inflation. Inflation and U.S. monetary policy maneuvers to reduce it may impact the Company’s customers’ demand for banking services and ability to qualify for and/or repay loans. These risks could adversely affect the Company’s business, financial condition, results of operations, cash flows, credit risk, asset valuations and capital position. Recent Accounting Pronouncements ASU 2023-09 In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The amendments in this ASU require an entity to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold, which is greater than five percent of the amount computed by multiplying pretax income by the entity’s applicable statutory rate, on an annual basis. Additionally, the amendments in this ASU require an entity to disclose the amount of income taxes paid (net of refunds received) disaggregated by federal, state, and foreign taxes and the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions that are equal to or greater than five percent of total income taxes paid (net of refunds received). Lastly, the amendments in this ASU require an entity to disclose income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign and income tax expense (or benefit) from continuing operations disaggregated by federal, state, and foreign. This ASU is effective for annual periods beginning after December 15, 2024. Early adoption is permitted.
