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 and six month periods ended June 30, 2020 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 2019 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 The outbreak of COVID-19 has adversely impacted a broad range of industries in which the Company’s customers operate and could impair their ability to fulfill their financial obligations to the Company. The World Health Organization declared COVID-19 to be a global pandemic and almost all public commerce and related business activities have been, to varying degrees, curtailed in order to reduce the rate of new infections. The 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 employees have not experienced a high level of infection, however a large outbreak amongst employees could create widespread business continuity issues for the Company. The Congress of the United States, along with the President of the United States and the Federal Reserve have taken historic actions. Most notably, the Coronavirus Aid, Relief and Economic Security (“CARES”) Act was signed into law at the end of March 2020 and provides $2 trillion to cushion the economic fallout. The CARES Act employs various measures in an attempt to prevent a severe economic downturn, including direct financial aid to American families and economic stimulus to significantly impacted industry sectors. The package also includes extensive emergency funding for hospitals and providers. Certain provisions of the CARES Act as well as other recent legislative and regulatory relief efforts have had and are expected to have a material impact on the Company’s operations. 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 that 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 Company’s fee income was negatively impacted during the second quarter of 2020 and may experience further declines. In keeping with guidance from regulators, the Company is actively working with COVID-19 affected customers and may waive various fees related to deposit and lending activities. The Company is continuously monitoring the situation and expects to continue to work with affected customers throughout the crisis in order to preserve its customer base. The Company will resume normal practices related to fees when the crisis eases. At this time, the Company is unable to project the materiality of such an impact, but recognizes the economic impact on fee income will extend to future periods. The Company’s interest income decreased during the second quarter of 2020 and the Company expects that interest income may continue at a lower than normal level while the pandemic continues to reduce borrower’s ability to repay. In keeping with guidance from regulators, the Company is actively working with COVID-19 affected borrowers to provide short-term payment relief, including providing payment extensions and interest-only periods, as well as rate reductions. For certain real estate secured loans, payment extensions result in reversal of previously accrued interest, immediately reducing interest income. Interest begins accruing again at the next payment date and the reversed interest will be recognized at the end of the loan term. Accrued interest on other loans is not reversed when the payment is extended. If eventual credit losses are identified on any loan that has received a payment extension or interest only period, interest and fee income accrued pursuant to U.S. GAAP accounting would be reversed at the time the loss is identified. In such a scenario, interest income in future periods could be negatively impacted. 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. 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, but rates for short term funding have shown volatility recently. If funding costs are elevated 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. 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. 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 is monitoring the value of its goodwill. Goodwill impairment testing considers the Company’s stock price among several factors in determining whether impairment exists. The COVID-19 pandemic has caused significant stock market volatility which has affected the Company’s stock price. The stock price level at June 30, 2020 caused the Company to perform internal analysis to determine whether goodwill testing should be updated. As of June 30, the Company determined that goodwill was not impaired. However, if the pandemic causes a further and 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 a goodwill impairment test. In the event that the Company concludes that all or a portion of its goodwill is impaired, a non-cash charge for the amount of such impairment would be recorded to earnings. Processes, controls and business continuity plan In response to the pandemic, the Company deployed its business continuity plan, including a remote working strategy for certain employees. The Company does not anticipate incurring additional material cost related to its continued deployment of the remote working strategy. The Company has assessed the risks associated with the remote working strategy and implemented mitigation strategies. No material operational or internal control challenges or risks have been identified to date. The Company does not anticipate significant challenges to its ability to maintain its systems and controls in light of the measures the Company has taken to prevent the spread of COVID-19. The Company does not currently face any material resource constraint through the implementation of its business continuity plans. Lending operations and accommodations to borrowers In keeping with regulatory guidance to work with borrowers during this unprecedented situation and as outlined in the CARES Act, the Company is providing modifications for its borrowers who are adversely affected by the pandemic. Depending on the demonstrated need of the borrower, the Company has provided payment extensions, granted periods of interest only payments to otherwise amortizing loans, and rate reductions. As of June 30, 2020, the Company has provided COVID-19 related accommodations on 297 loans with aggregate outstanding loan balances of $119,711. In accordance with interagency guidance issued in March 2020 and revised in April 2020, these short term extensions are not considered troubled debt restructurings (“TDRs”). The Company is monitoring loans with payment extensions, with special attention to loans with payment extensions that exceed 60 days to determine whether changes in risk rates or TDR status is warranted. 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. Most of the PPP loans the Company made have a two-year term and earn interest at 1%. Guidance issued by the SBA during the second wave of funding provided terms of up to five years. If borrowers request a change from 2 years to 5 years, the Company will likely grant the request. The Company believes that the majority of these loans will ultimately be forgiven by the SBA in accordance with the terms of the program. As of June 30, 2020, the Company holds $55,819 PPP loans, net of deferred fees and costs. It is the Company’s understanding that loans funded through the PPP program are fully guaranteed by the U.S. government. 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 regulator 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.
