Notes to Financial Statements
Significant Accounting Policies [Text Block]	Note 1: Summary of Significant Accounting Policies The consolidated financial statements include the accounts of National Bankshares, Inc. and its wholly-owned subsidiaries, the National Bank of Blacksburg, and National Bankshares Financial Services, Inc. All intercompany balances and transactions have been eliminated in consolidation. The accounting and reporting policies of the Company conform to GAAP and to general practices within the banking industry. The following is a summary of significant accounting policies. Subsequent events have been considered through the date of this Form 10 Cash and Cash Equivalents For purposes of the consolidated statements of cash flows, cash and cash equivalents include cash and amounts due from banks. Interest-Bearing Deposits The Company invests over-night funds in interest-bearing deposits at other banks, including the FHLB, the Federal Reserve and other entities. Interest-bearing deposits are carried at cost. Securities Certain debt securities that management has the positive intent and ability to hold to maturity may not During 2018, $119,790 $1,128. The Company follows the accounting guidance related to recognition and presentation of OTTI. The guidance specifies that if (a) an entity does not not not not Equity securities with readily-determinable fair values are measured at fair value using the “exit price notion”. Changes in fair value are recognized in net income. Equity securities without readily-determinable fair values are recorded as other assets at cost less impairment, if any, and adjusted for changes resulting from observable price changes in orderly transactions for identical or similar investment of the same issuer. Loans Held for Sale Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value on an individual loan basis. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income. The Company releases mortgage servicing rights when loans are sold on the secondary market. Loans The Company, through its banking subsidiary, provides mortgage, commercial, and consumer loans to customers. A substantial portion of the loan portfolio is represented by mortgage loans, particularly commercial mortgages. The ability of the Company’s debtors to honor their contracts is dependent upon the real estate and general economic conditions in the Company’s market area. The Company’s loans are grouped into six Real estate construction loans are subject to general risks from changing commercial building and housing market trends and economic conditions that may not may The credit quality of consumer real estate is subject to risks associated with the borrower’s repayment ability and collateral value, measured generally by analyzing local unemployment and bankruptcy trends, and local housing market trends and interest rates. Risks specific to a borrower are determined by previous repayment history, loan-to-value ratios and debt-to-income ratios. The commercial real estate segment includes loans secured by multifamily residential real estate, commercial real estate occupied by the owner/borrower, and commercial real estate leased to non-owners. Loans in the commercial real estate segment are impacted by economic risks from changing commercial real estate markets, rental markets for multi-family housing and commercial buildings, business bankruptcy rates, local unemployment rates and interest rate trends that would impact the businesses housed by the commercial real estate. Commercial non-real estate loans are secured by collateral other than real estate, or are unsecured. Credit risk for commercial non-real estate loans is subject to economic conditions, generally monitored by local business bankruptcy trends, interest rates, borrower repayment ability and collateral value (if secured). Public sector and IDA loans are extended to municipalities and related entities. Credit risk is based upon the entity’s ability to repay through either a direct obligation or assignment of specific revenues from an enterprise or other economic activity, and interest rate trends. Consumer non-real estate includes credit cards, automobile and other consumer loans. Credit cards and certain other consumer loans are unsecured, while collateral is obtained for automobile loans and other consumer loans. Credit risk stems primarily from the borrower’s ability to repay. If the loan is secured, the company analyzes loan-to-value ratios. All consumer non-real estate loans are analyzed for debt-to-income ratios and previous credit history, as well as for general risks for the portfolio, including local unemployment rates, personal bankruptcy rates and interest rates. Risks from delinquency trends and characteristics such as second Loans that management has the intent and ability to hold for the foreseeable future, or until maturity or payoff, generally are reported at their outstanding unpaid principal balances adjusted for the allowance for loan losses, any purchase premium or discount, unearned income and deferred fees or costs. Interest income is accrued on the unpaid principal balance. Unearned income on dealer-originated loans and loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method. Purchase premium or discount is recognized as an adjustment of the related loan yield using the interest method. The Company considers multiple factors when determining whether to discontinue accrual of interest on individual loans. Generally loans are placed in nonaccrual status when collection of interest and/or full principal is considered doubtful. Interest accrual is discontinued at the time a commercial real estate loan or commercial non-real estate loan is 90 not 90 six may All interest accrued but not not may six A loan is considered past due when a payment of principal and/or interest is due but not not 30 not not 30 30 89 90 Allowance for Loan Losses The allowance for loan losses represents management’s estimate of probable losses inherent in the Company’s loan portfolio. A provision for estimated losses is charged to earnings to establish and maintain the allowance for loan losses at a level reflective of the estimated credit risk. When management determines that a loan balance or portion of a loan balance is not Management evaluates the allowance each quarter through a methodology that estimates losses on individual impaired loans and evaluates the effect of numerous factors on the credit risk of groups of homogeneous loans. Specific allowances are established for individually-evaluated impaired loans based on the excess of the loan balance relative to the fair value of the loan. Impaired loans are designated as such when current information indicates that it is probable that the Company will be unable to collect principal or interest when due according to the contractual terms of the loan agreement. Loan relationships exceeding $250 not Fair value of impaired loans is estimated in one three 1 2 3 General allowances are established for collectively evaluated loans. Collectively evaluated loans are grouped into classes based on similar characteristics. Factors considered in determining general allowances include net charge-off trends, internal risk ratings, delinquency and nonperforming rates, product mix, underwriting practices, industry trends and economic trends. The Company’s charge-off policy meets or is more stringent than the minimum standards required by regulators. When available information confirms that a specific loan or a portion thereof, within any loan class, is uncollectible the amount is charged off against the allowance for loan losses. Additionally, losses on consumer real estate and consumer non-real estate loans are typically charged off no 120 180 180 may may Troubled Debt Restructurings In situations where, for economic or legal reasons related to a borrower’s financial condition, management grants a concession to the borrower that it would not may may one Rate Lock Commitments The Company enters into commitments to originate mortgage loans in which the interest rate on the loan is determined prior to funding (rate lock commitments). Rate lock commitments on mortgage loans that are intended to be sold are considered to be derivatives. The period of time between issuance of a loan commitment and closing and sale of the loan generally ranges from 30 60 not The market value of rate lock commitments and best efforts contracts is not not no Premises and Equipment Land is carried at cost. Premises and equipment are stated at cost, net of accumulated depreciation. Depreciation is charged to expense over the estimated useful lives of the assets on the straight-line basis. Depreciable lives include 40 3 10 3 Other Real Estate Owned Real estate acquired through or in lieu of foreclosure is held for sale and is initially recorded at fair value less estimated costs to sell at the date of foreclosure, establishing the cost basis of the asset. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less estimated costs to sell. Revenue and expenses from operations and changes in the valuation allowance are included in other operating expenses. Goodwill The Company records as goodwill the excess of purchase price over the fair value of the identifiable net assets acquired. Goodwill is subject to at least an annual assessment for impairment by applying a fair value based test. The Company performs its annual analysis as of September 30 two first second The Company’s goodwill impairment analysis considered three first second third 100% no second third Each measure indicated that the Company’s fair value exceeded its book value. No December 31, 2019, 2018 2017. The Company’s intangible assets became fully amortized during 2018. 10 12 Pension Plan The Company recognizes the overfunded or underfunded status of a defined benefit postretirement plan as an asset or liability in its statement of financial position and recognizes changes in that funded status in the year in which the changes occur through comprehensive income. The funded status of a benefit plan is measured as the difference between plan assets at fair value and the projected benefit obligation. Income Taxes Income tax accounting guidance results in two Deferred income tax expense results from changes in deferred tax assets and liabilities between periods.

The Company recognizes noninterest income when it satisfies commitments to customers. Please refer to Note 18: Use of Estimates In preparing consolidated financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated balance sheet and 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, the valuation of other real estate owned, other-than-temporary impairments of securities, evaluation of impairment of goodwill, and pension obligations. Changing economic conditions, adverse economic prospects for borrowers, as well as regulatory agency action as a result of examination, could cause NBB to recognize additions to the allowance for loan losses and may Acco unting Standards Adopted in 2019 ASU No. 2016 02, 842 In February 2016, No. 2016 02, 842 1 2 not may not Subsequent to the issuance of ASU 2016 02, No. 2018 01, 842 842,” No. 2018 10, 842, No. 2018 11, 842 No. 2018 20, 842 No. 2019 01 842 2018 11 840, Upon adoption on January 1, 2019, 2018 11. no not not not January 1, 2019 12 January 1, 2019.

Allowance for Credit Losses [Text Block]	Note 5: The allowance for loan losses methodology incorporates individual evaluation of impaired loans and collective evaluation of groups of non-impaired loans. The Company performs ongoing analysis of the loan portfolio to determine credit quality and to identify impaired loans. Credit quality is rated based on the loan’s payment history, the borrower’s current financial situation and value of the underlying collateral. 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 will not not not six may 1: TDRs impact the estimation of the appropriate level of the allowance for loan losses. If the restructuring included forgiveness of a portion of principal or accrued interest, the charge-off is included in the historical charge-off rates applied to the collective evaluation methodology. Restructured loans are individually evaluated for impairment, and the amount of a TDR’s book value in excess of its fair value is accrued as a specific allocation in the allowance for loan losses. If a TDR loan payment exceeds 90 not may Collectively-Evaluated Loans The Company evaluated characteristics in the loan portfolio and determined major segments and smaller classes within each segment. These characteristics include collateral type, repayment sources, and (if applicable) the borrower’s business model. The methodology for calculating reserves for collectively-evaluated loans is applied at the class level. Portfolio Segments and Classes The segments and classes used in determining the allowance for loan losses are as follows. Real Estate Construction Construction, residential Construction, other Consumer Real Estate Equity lines Residential closed-end first Residential closed-end junior liens Investor-owned residential real estate Commercial Real Estate Multifamily real estate Commercial real estate, owner-occupied Commercial real estate, other Commercial Non Real Estate Commercial and Industrial Public Sector and IDA Public sector and IDA Consumer Non Real Estate Credit cards Automobile Other consumer loans Historical Loss Rates The Company’s allowance methodology for collectively-evaluated loans applies historical loss rates by class to current class balances as part of the process of determining required reserves. Class loss rates are calculated as the net charge-offs for the class as a percentage of average class balance. The Company averages loss rates for the most recent eight Two loss rates for each class are calculated: total net charge-offs for the class as a percentage of average class loan balance (“class loss rate”), and total net charge-offs for the class as a percentage of average classified loans in the class (“classified loss rate”). Classified loans are those with risk ratings of “substandard” or lower. Net charge-offs in both calculations include charge-offs and recoveries of classified and non-classified loans as well as those associated with impaired loans. Class historical loss rates are applied to non-classified loan balances at the reporting date, and classified historical loss rates are applied to classified balances at the reporting date. Risk Factors In addition to historical loss rates, risk factors pertinent to credit risk for each class are analyzed to estimate reserves for collectively-evaluated loans. Factors include changes in national and local economic and business conditions, the nature and volume of classes within the portfolio, loan quality, loan officers’ experience, lending policies and the Company’s loan review system. The analysis of certain factors results in standard allocations to all segments and classes. These factors include the risk from changes in lending policies, loan officers’ average years of experience, unemployment levels, bankruptcy rates, interest rate environment, and competition/legal/regulatory environments. Factors analyzed for each class, with resultant allocations based upon the level of risk assessed for each class, include the risk from changes in loan review, levels of past due loans, levels of nonaccrual loans, current class balance as a percentage of total loans, and the percentage of high risk loans within the class. Additionally, factors specific to each segment are analyzed and result in allocations to the segment. Please refer to Note 1: Real estate construction loans are subject to general risks from changing commercial building and housing market trends and economic conditions that may The credit quality of consumer real estate is subject to risks associated with the borrower’s repayment ability and collateral value, measured generally by analyzing local unemployment and bankruptcy trends, local housing market trends, and interest rates. The commercial real estate segment includes loans secured by multifamily residential real estate, commercial real estate occupied by the owner/borrower, and commercial real estate leased to non-owners. Loans in the commercial real estate segment are impacted by economic risks from changing commercial real estate markets, rental markets for multi-family housing and commercial buildings, business bankruptcy rates, local unemployment and interest rate trends that would impact the businesses housed by the commercial real estate. Commercial non real estate loans are secured by collateral other than real estate, or are unsecured. Credit risk for commercial non real estate loans is subject to economic conditions, generally monitored by local business bankruptcy trends, and interest rates. Public sector and IDA loans are extended to municipalities and related entities. Credit risk is based upon the entity’s ability to repay and interest rate trends. Consumer non real estate includes credit cards, automobile and other consumer loans. Credit cards and certain other consumer loans are unsecured, while collateral is obtained for automobile loans and other consumer loans. Credit risk stems primarily from the borrower’s ability to repay, measured by average unemployment, average personal bankruptcy rates and interest rates. Factor allocations applied to each class are increased for loans rated special mention and increased to a greater extent for loans rated classified. The Company allocates additional reserves for “high risk” loans. High risk loans include junior liens, interest only and high loan to value loans.

Regulatory Capital Requirements under Banking Regulations [Text Block]	Note 1 1: Prior to 2018, 2018 August 2018, NBB continues to be subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on NBI’s and NBB’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, NBB must meet specific capital guidelines that involve quantitative measures of their assets, liabilities, and certain off balance sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by regulators about components, risk weightings, and other factors. The Bank is subject to the rules implementing the Basel III capital framework and certain related provisions of the Dodd-Frank Act (the “Basel III Capital Rules”) as applied by the Office of the Comptroller of the Currency. The Basel III Capital Rules require the Bank to comply with minimum capital ratios plus a “capital conservation buffer” designed to absorb losses during periods of economic stress.

Fair Value Disclosures [Text Block]	Note 1 5 : Fair Value Measurements Fair value is defined as the exchange price that would be received for 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 on the measurement date. GAAP requires that valuation techniques maximize the use of the observable inputs and minimize the use of the unobservable inputs. GAAP also establishes a fair value hierarchy which prioritizes the valuation inputs into three one three 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 Fair value is best determined based upon quoted market prices. However, in many instances, there are no not may not may not The following describes the valuation techniques used by the Company to measure certain financial assets and liabilities recorded at fair value on a recurring basis in the financial statements: Securities A vailable for S ale Securities available for sale are recorded at fair value on a recurring basis.

Topic 606 not 606 not 606. 606 Service Charges on Deposit Accounts Service charges on deposit accounts consist of monthly service fees, overdraft and nonsufficient funds fees, ATM fees, wire transfer fees and other deposit account related fees. The Company’s performance obligation for monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers’ accounts. ATM fees are primarily generated when a Company cardholder uses a non-Company ATM or a non-Company cardholder uses a Company ATM. Wire transfer fees, overdraft and nonsufficient funds fees and other deposit account related fees are transactional based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, at a point in time. Other Service Charges and Fees Other service charges include safety deposit box rental fees, check ordering charges, and other service charges. Safe deposit box rental fees are charged to the customer on an annual basis and recognized upon receipt of payment. The Company determined that since rentals and renewals occur fairly consistently over time, revenue is recognized on a basis consistent with the duration of the performance obligation. Check ordering charges are transactional based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, at a point in time. Credit and Debit Card Fees Credit and debit card fees are primarily comprised of interchange fee income and, prior to mid- 2017, 2017. 606, Trust Income Trust income is primarily comprised of fees earned from the management and administration of trusts and other customer assets. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the month-end market value of the assets under management and the applicable fee rate. Payment is generally received a few days after month end through a direct charge to customers’ accounts. The Company does not Insurance and Investment Insurance income primarily consists of commissions received on insurance product sales. The Company acts as an intermediary between the Company’s customer and the insurance carrier. The Company’s performance obligation is generally satisfied upon the issuance of the insurance policy. Shortly after the insurance policy is issued, the carrier remits the commission payment to the Company, and the Company recognizes the revenue. Investment income consists of recurring revenue streams such as commissions from sales of mutual funds and other investments. Commissions from the sale of mutual funds and other investments are recognized on trade date, which is when the Company has satisfied its performance obligation. The Company also receives periodic service fees (i.e., trailers) from mutual fund companies typically based on a percentage of net asset value. Trailer revenue is recorded over time, usually monthly or quarterly, as net asset value is determined.

Changes in fair value are recognized in net income. Equity securities without readily-determinable fair values are recorded as other assets at cost less impairment, if any, and adjusted for changes resulting from observable price changes in orderly transactions for identical or similar investment of the same issuer.
Financing Receivable, Held-for-sale [Policy Text Block]	Loans Held for Sale Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value on an individual loan basis. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income. The Company releases mortgage servicing rights when loans are sold on the secondary market.
Financing Receivable, Held-for-investment [Policy Text Block]	Loans The Company, through its banking subsidiary, provides mortgage, commercial, and consumer loans to customers. A substantial portion of the loan portfolio is represented by mortgage loans, particularly commercial mortgages. The ability of the Company’s debtors to honor their contracts is dependent upon the real estate and general economic conditions in the Company’s market area. The Company’s loans are grouped into six Real estate construction loans are subject to general risks from changing commercial building and housing market trends and economic conditions that may not may The credit quality of consumer real estate is subject to risks associated with the borrower’s repayment ability and collateral value, measured generally by analyzing local unemployment and bankruptcy trends, and local housing market trends and interest rates. Risks specific to a borrower are determined by previous repayment history, loan-to-value ratios and debt-to-income ratios. The commercial real estate segment includes loans secured by multifamily residential real estate, commercial real estate occupied by the owner/borrower, and commercial real estate leased to non-owners. Loans in the commercial real estate segment are impacted by economic risks from changing commercial real estate markets, rental markets for multi-family housing and commercial buildings, business bankruptcy rates, local unemployment rates and interest rate trends that would impact the businesses housed by the commercial real estate. Commercial non-real estate loans are secured by collateral other than real estate, or are unsecured. Credit risk for commercial non-real estate loans is subject to economic conditions, generally monitored by local business bankruptcy trends, interest rates, borrower repayment ability and collateral value (if secured). Public sector and IDA loans are extended to municipalities and related entities. Credit risk is based upon the entity’s ability to repay through either a direct obligation or assignment of specific revenues from an enterprise or other economic activity, and interest rate trends. Consumer non-real estate includes credit cards, automobile and other consumer loans. Credit cards and certain other consumer loans are unsecured, while collateral is obtained for automobile loans and other consumer loans. Credit risk stems primarily from the borrower’s ability to repay. If the loan is secured, the company analyzes loan-to-value ratios. All consumer non-real estate loans are analyzed for debt-to-income ratios and previous credit history, as well as for general risks for the portfolio, including local unemployment rates, personal bankruptcy rates and interest rates. Risks from delinquency trends and characteristics such as second Loans that management has the intent and ability to hold for the foreseeable future, or until maturity or payoff, generally are reported at their outstanding unpaid principal balances adjusted for the allowance for loan losses, any purchase premium or discount, unearned income and deferred fees or costs. Interest income is accrued on the unpaid principal balance. Unearned income on dealer-originated loans and loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method. Purchase premium or discount is recognized as an adjustment of the related loan yield using the interest method. The Company considers multiple factors when determining whether to discontinue accrual of interest on individual loans. Generally loans are placed in nonaccrual status when collection of interest and/or full principal is considered doubtful. Interest accrual is discontinued at the time a commercial real estate loan or commercial non-real estate loan is 90 not 90 six may All interest accrued but not not may six A loan is considered past due when a payment of principal and/or interest is due but not not 30 not not 30 30 89 90
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Allowance for Loan Losses The allowance for loan losses represents management’s estimate of probable losses inherent in the Company’s loan portfolio. A provision for estimated losses is charged to earnings to establish and maintain the allowance for loan losses at a level reflective of the estimated credit risk. When management determines that a loan balance or portion of a loan balance is not Management evaluates the allowance each quarter through a methodology that estimates losses on individual impaired loans and evaluates the effect of numerous factors on the credit risk of groups of homogeneous loans. Specific allowances are established for individually-evaluated impaired loans based on the excess of the loan balance relative to the fair value of the loan. Impaired loans are designated as such when current information indicates that it is probable that the Company will be unable to collect principal or interest when due according to the contractual terms of the loan agreement. Loan relationships exceeding $250 not Fair value of impaired loans is estimated in one three 1 2 3 General allowances are established for collectively evaluated loans. Collectively evaluated loans are grouped into classes based on similar characteristics. Factors considered in determining general allowances include net charge-off trends, internal risk ratings, delinquency and nonperforming rates, product mix, underwriting practices, industry trends and economic trends. The Company’s charge-off policy meets or is more stringent than the minimum standards required by regulators. When available information confirms that a specific loan or a portion thereof, within any loan class, is uncollectible the amount is charged off against the allowance for loan losses. Additionally, losses on consumer real estate and consumer non-real estate loans are typically charged off no 120 180 180 may may

Financing Receivable, Real Estate Acquired Through Foreclosure [Policy Text Block]	Other Real Estate Owned Real estate acquired through or in lieu of foreclosure is held for sale and is initially recorded at fair value less estimated costs to sell at the date of foreclosure, establishing the cost basis of the asset. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less estimated costs to sell. Revenue and expenses from operations and changes in the valuation allowance are included in other operating expenses.
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill The Company records as goodwill the excess of purchase price over the fair value of the identifiable net assets acquired.

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, the valuation of other real estate owned, other-than-temporary impairments of securities, evaluation of impairment of goodwill, and pension obligations. Changing economic conditions, adverse economic prospects for borrowers, as well as regulatory agency action as a result of examination, could cause NBB to recognize additions to the allowance for loan losses and may

[1]	Except with regard to the Bank's Tier 1 capital to average assets ratio, the minimum capital requirement includes the current phased-in portion of the Basel III Capital Rules capital conservation buffer (2.50% for 2019 and 1.875% in 2018) which is added to the minimum capital requirements for capital adequacy purposes. The capital conservation buffer was phased in through four equal annual installments of .0625% from 2016 to 2019, with full implementation in January 2019. The Bank's capital conservation buffer consists of additional CET1 above regulatory minimum requirement. Failure to maintain the prescribed levels would result in limitations on capital distributions and discretionary bonuses to executives.
