Notes to Financial Statements
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Note 1: General 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 (“U.S. GAAP”) and to general practices within the banking industry. The accompanying interim period consolidated financial statements are unaudited; however, in the opinion of management, all adjustments consisting of normal recurring adjustments, which are necessary for a fair presentation of the consolidated financial statements, have been included. The results of operations for the three month period ended March 31, 2021 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 2020 Form 10-K. The Company posts all reports required to be filed under the Securities Exchange Act of 1934 on its web site at www.nationalbankshares.com. Risks and Uncertainties Over the past year, the COVID-19 pandemic and efforts to reduce its spread have caused significant disruptions in the U.S. economy and negatively impacted financial activity in the Company’s market. The Company’s business is dependent upon the willingness and ability of its employees and customers to conduct banking and other financial transactions. If the global response to contain COVID-19 escalates further or is unsuccessful, the Company could experience a material adverse effect on its business, financial condition, results of operations and cash flows. While it is not possible to know the full extent of the impact COVID-19 will have on the Company’s operations, the Company is disclosing potentially material items of which it is aware. Financial position and results of operations The pandemic led to declines in two key income categories during 2020: interest income and overdraft fee income. Interest income was impacted by modification requests and by a decreased interest rate environment. During the first quarter of 2021, the number of modification requests that reduce interest income vastly decreased, though loan refinance and securities call activity spurred by the low interest rates continue to impact interest income, with reinvestment opportunities at lower rates. The Company does not expect the Federal Reserve to increase rates in the near future. If the pandemic’s evolution brings new or worsened economic impacts, these income categories and others may be negatively affected. Lending operations and accommodations to borrowers Modifications to loans for borrowers affected by COVID-19 provided payment relief. Depending on the demonstrated need of the borrower, the Company provided payment extensions, periods of interest only payments to otherwise amortizing loans, and interest rate reductions. The Company is monitoring loans with payment extensions, with special attention to loans with payment extensions that exceed 90 days, as well as subsequent requests for modifications to determine whether changes in risk ratings, accrual status or designation as a troubled debt restructuring (“TDR”) is warranted. If eventual credit losses are identified on these or other loans, accrued interest and fee income would be reversed at the time the loss is identified. If the loans are fully or partially charged off, future requirements for the provision for loan losses will increase. At this time, the Company is unable to project the materiality of such an impact, but recognizes economic declines may affect its borrowers’ ability to repay in future periods. The Company is closely monitoring the crisis and expects to continue to work with customers when warranted in order to preserve income potential and customer base. With the passage of the Paycheck Protection Program (“PPP”), administered by the Small Business Administration (“SBA”), the Company is actively participating in assisting its customers through the program. It is the Company’s understanding that loans funded through the PPP program are fully guaranteed by the U.S. government and that the majority of these loans will ultimately be forgiven by the SBA in accordance with the terms of the program. Should those circumstances change, the Company could be required to establish additional allowance for loan loss through provision for loan loss charged to earnings. Credit The Company is working with customers directly affected by COVID-19, providing short-term assistance in accordance with regulatory guidelines. As a result of the current economic environment caused by the COVID-19 pandemic, the Company is engaging in more frequent communication with borrowers to better understand their situation and the challenges faced, allowing it to respond proactively as needs and issues arise. Should economic conditions worsen, the Company could experience further increases in its required allowance for loan loss and record additional loan loss expense. It is possible that the Company’s asset quality measures could worsen at future measurement periods if effects of the COVID-19 pandemic are prolonged. Asset valuation Currently, the Company does not expect COVID-19 to affect its ability to account timely for the assets on its balance sheet; however if the impact of the pandemic worsens, valuation procedures in future periods could be negatively affected. While certain valuation assumptions and judgments will change to account for pandemic-related circumstances, such as widening credit spreads, the Company does not anticipate significant changes in methodology used to determine the fair value of assets measured in accordance with U.S. GAAP. The Company tests goodwill for impairment annually, usually during the fourth quarter using September 30 information, unless facts and circumstances indicate the need for more frequent impairment testing. If the evolution of the pandemic or other adverse events cause a sustained decline in the Company’s stock price or the occurrence of what management deems to be a triggering event, under certain circumstances prescribed by U.S. GAAP, the Company will perform goodwill impairment testing as needed, which may be more frequently than annually. In the event that testing indicates that all or a portion of goodwill is impaired, a non-cash charge for the amount of such impairment would be recorded to earnings. Capital and liquidity While the Company believes that it has sufficient capital to withstand an extended economic recession brought about by COVID-19, its reported and regulatory capital ratios could be adversely impacted by further credit losses. The Company maintains access to multiple sources of liquidity. Wholesale funding markets are currently available to the Company. If the uncertainty caused by the COVID-19 pandemic results in volatile or elevated funding costs for an extended period of time and if it becomes necessary for the Company to access wholesale funding, the Company’s net interest margin could be adversely affected. Deposits have increased since the beginning of the pandemic, however, if an extended recession causes large numbers of the Company’s deposit customers to withdraw their funds, the Company might become more reliant on volatile or more expensive sources of funding. Accounting Standards Adopted as of January 1, 2021 In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740) – Simplifying the Accounting for Income Taxes.” The amendments are expected to reduce cost and complexity related to the accounting for income taxes by removing specific exceptions to general principles in Topic 740 (eliminating the need for an organization to analyze whether certain exceptions apply in a given period) and improving financial statement preparers’ application of certain income tax-related guidance. This ASU is part of the FASB’s simplification initiative to make narrow-scope simplifications and improvements to accounting standards through a series of short-term projects. ASU 2019-12 was effective for the Company on January 1, 2021. The adoption of ASU 2019-12 did not have a material impact on the Company’s consolidated financial statements. In January 2020, the FASB issued ASU 2020-01, “Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)—Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 (a consensus of the Emerging Issues Task Force).” The ASU is based on a consensus of the Emerging Issues Task Force and is expected to increase comparability in accounting for these transactions. ASU 2016-01 made targeted improvements to accounting for financial instruments, including providing an entity the ability to measure certain equity securities without a readily determinable fair value at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. Among other topics, the amendments clarify that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting. ASU 2020-01 was effective for the Company on January 1, 2021. The adoption of ASU 2020-01 did not have a material impact on the Company’s consolidated financial statements. In October 2020, the FASB issued ASU 2020-08, “Codification Improvements to Subtopic 310-20, Receivables – Nonrefundable fees and Other Costs.” This ASU clarifies that an entity should reevaluate whether a callable debt security is within the scope of ASC paragraph 310-20-35-33 for each reporting period. ASU 2020-08 was effective for the Company on January 1, 2021. The adoption of ASU 2020-08 did not have a material impact on the Company’s consolidated financial statements. Recent Accounting Pronouncements In June 2016, the FASB issued Accounting Standards Update (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 FASB has issued multiple updates to ASU 2016-13 as codified in Topic 326, including ASU’s 2019-04, 2019-05, 2019-10, 2019-11, 2020-02, and 2020-03. These ASU’s have provided for various minor technical corrections and improvements to the codification as well as other transition matters. Smaller reporting companies who file with the U.S. Securities and Exchange Commission (“SEC”) and all other entities who do not file with the SEC are required to apply the guidance for fiscal years, and interim periods within those years, beginning after December 15, 2022. The Company is currently assessing the impact that ASU 2016-13 will have on its consolidated financial statements. Management is working to ensure readiness and compliance with the standard and has implemented coding of the loan portfolio to enable appropriate segregation and data integrity, analyzed correlations for forecasting, determined methodologies, and selected a vendor to provide a platform. Management has prepared multiple concurrent models using the Current Expected Credit Losses (“CECL”) methodology and will continue to refine assumptions that impact the calculation prior to the effective date. Effective November 25, 2019, the SEC adopted Staff Accounting Bulletin (“SAB”) 119. SAB 119 updated portions of SEC interpretative guidance to align with FASB Accounting Standards Codification (“ASC 326”), “Financial Instruments – Credit Losses.” It covers topics including (1) measuring current expected credit losses; (2) development, governance, and documentation of a systematic methodology; (3) documenting the results of a systematic methodology; and (4) validating a systematic methodology. 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.” These amendments 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 does not expect the adoption of ASU 2018-14 to have a material impact on its consolidated financial statements.
