Notes to Financial Statements
Significant Accounting Policies [Text Block]	Note 1: 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. 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 The Company follows the accounting guidance related to recognition and presentation of other–than-temporary impairment (“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. Loans that management has the intent and ability to hold for the foreseeable future, or until maturity or payoff, 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 Bank’s loan policy is updated and approved by the Board of Directors annually and disseminated to lending and loan portfolio management personnel to ensure consistent lending practices. The policy communicates the Company’s risk tolerance by prescribing underwriting guidelines and procedures, including approval limits and hierarchy, documentation standards, requirements for collateral and loan-to-value limits, debt coverage, overall creditworthiness and guarantor support. Of primary consideration is the repayment ability of the borrowers and (if secured) the collateral value in relation to the principal balance. Collateral lowers risk and may The Company’s loans are grouped into six Real Estate Construction Loans. may not may may Consumer Real Estate Loans. first 80% 43% Consumer real estate mortgages may fifth Home equity loans are secured primarily by second 80% not We do not may Commercial Real Estate Loans. first 80% 115% may may Commercial Non Real Estate Loans. 60% 90% 70% 90 Public Sector and IDA Loans. Consumer Non-Real Estate Loans. TDRs Loan modifications are reviewed at the time of modification to determine whether the loan should be designated as TDR. When the Company grants a concession to a borrower for economic or legal reasons related to a borrower’s financial condition, the loan is classified as a TDR. When the Company grants a subsequent modification to a loan that had previously been modified but not may may one Past due status and nonaccrual designation A loan is considered past due when a payment of principal and/or interest is due but not not 30 not not 30 89 90 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 days delinquent unless the credit is well secured and in the process of collection. Loans modified to provide relief from payments of interest or principle for more than 90 Loans in nonaccrual are reviewed on an individual loan basis to determine whether they may not may six Charge-off policy 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 may may Allowance for Loan Losses The allowance for loan losses is an estimate of probable losses inherent in the loan portfolio. The allowance is funded by the provision for loan losses, reduced by charge-offs of loans and increased by recoveries of previously charged-off loans. The determination of the allowance is based on two 450 20 310 10 The Company 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 ("collectively evaluated loans"). Impaired loans Impaired loans are larger non-homogeneous loans for which there is a probability that collection of principal or interest will not not Impaired loan measurement methods Impaired loans are individually evaluated to determine appropriate reserves and are measured at the lower of the invested amount or the fair value. Fair value of impaired loans is estimated by either the present value of the loan’s expected future cash flows (“cash flow method”) or the estimated fair value, less selling costs, of the underlying collateral (“collateral method”). Cash flow method: The cash flow method is applied to loans that are not may 90 Collateral method: The collateral method is applied to impaired loans that are collateral-dependent, for which foreclosure is imminent or for which non-collateral repayment sources are determined not may Impaired loans secured by residential 1 4 1 4 third Appraisals must conform to the Uniform Standards of Professional Appraisal Practice and are prepared by an independent third may Evaluations are prepared by third third Updated appraisals or evaluations are ordered when a loan becomes impaired if the appraisal or evaluation on file is more than 24 may not may Results of fair value measurement The estimated fair value is compared with the loan’s recorded investment (unpaid principal net of any interest payments made during the nonaccrual period and net of any partial charge-offs, accrued interest and deferred fees and costs). Any amount of recorded investment that exceeds estimated fair value on collateral-dependent loans, as well as any other impairment loss considered uncollectible, is charged against the allowance for loan losses. Fair value shortfalls that are not not no not Nonaccrual status of impaired loans Nonaccrual status is applied to impaired loans that are not 90 six may Collectively evaluated loans 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 historical loss rates, credit quality indicators, and qualitative factors. Loss rates Loss rates are calculated for and applied to individual classes by averaging loss rates over the most recent eight 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”). Net charge-offs in both calculations include charge-offs and recoveries for all loans within the class, including classified and non-classified loans, as well as impaired and TDR loans. Class historical loss rates are applied to collectively evaluated pass-rated loan balances and special mention rated loan balances, and classified historical loss rates are applied to collectively evaluated classified loan balances. Credit quality indicators Credit quality indicators, which the Company terms risk grades, are assigned through the Company’s credit review function for larger loans and selective review of loans that fall below credit review thresholds. Credit quality is rated based on the loan’s payment history, the borrower’s current financial situation and value of the underlying collateral. Loans that do not 75 75 Qualitative factor allocations The analysis of certain factors results in standard allocations to all classes. These factors include the risk from changes in lending policies, loan officers’ experience, changes in loan review, and economic factors including local unemployment levels, local bankruptcy rates, interest rate environment, and competition/legal/regulatory environments. Standard allocations for residential vacancy rates and housing inventory are applied to all real-estate secured classes and state and political subdivision loans. Qualitative factors incorporate economic data targeted to the Company’s market. If market–specific information is not may 2021, 19 not 2022. Factors analyzed for each class, with resultant allocations based upon the level of risk assessed for each class, include 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. High risk loans include junior liens, interest only and high loan to value loans. High risk loans within each class are analyzed and allocated additional reserves based on current trends. Allocations for qualitative factors are determined for pass-rated loans. To reflect the increased risk of criticized assets, qualitative factor allocations are multiplied by 150% for special mention loans, and multiplied by 200% for classified loans. Sales, purchases and reclassification of loans The Company finances consumer real estate mortgages under “best efforts” contracts with mortgage purchasers. The mortgages are designated as held for sale upon initiation. There have been no not Occasionally, the Company purchases or sells participations in loans. All participation loans purchased met the Company’s normal underwriting standards at the time the participation was entered. Participation loans are included in the appropriate portfolio balances to which the allowance methodology is applied. Unallocated surplus In addition to funding the allowance for loan losses based upon data analysis, the Company has the option to fund an unallocated surplus in excess to the calculated requirement, based upon management judgement. The Company’s policy permits an unallocated surplus of between 0% and 5% of the calculated requirement. Estimation of the allowance for loan losses The estimation of the allowance involves analysis of internal and external variables, methodologies, assumptions and management’s judgment and experience. Key judgments used in determining the allowance for loan losses include internal risk rating determinations, market and collateral values, discount rates, loss rates, and management’s assessment of current economic conditions. These judgments are inherently subjective and actual losses could be greater or less than the estimate. Future estimates of the allowance could increase or decrease based on changes in the financial condition of individual borrowers, concentrations of various types of loans, economic conditions or the markets in which collateral may 5 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 to 60 days. The Company protects itself from changes in interest rates through the use of best efforts forward delivery commitments, by committing to sell a loan at the time the borrower commits to an interest rate with the intent that the buyer has assumed interest rate risk on the loan. As a result, the Company is 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 years for premises, 3-10 years for furniture and equipment, and 3 years for computer software. Costs of maintenance and repairs are charged to expense as incurred and improvements are capitalized. 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 contracts with a third September 30 2022 September 30, 2022. Accounting guidance provides the option of performing preliminary assessment of qualitative factors to determine whether impairment testing is necessary. The Company opted not three first second third Certain key judgments were used in the valuation measurement. Goodwill is held by the Company’s bank subsidiary. The bank subsidiary is 100% owned by the Company, and no second third September 30, 2022, 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 other comprehensive loss. The funded status of a benefit plan is measured as the difference between plan assets at fair value and the projected benefit obligation. The Company’s actuary determines plan obligations and annual pension expense using a number of key assumptions, including the discount rate, the estimated return on plan assets and the anticipated rate of compensation increases. Changes in these assumptions in the future, if any, or in the method under which benefits are calculated may Income Taxes Income tax accounting guidance results in two Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, not 50 not 50 not not not not The Company recognizes interest and penalties on income taxes as a component of income tax expense.

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, ● inputs other than quoted prices that are observable, and ● model-based valuation techniques for which significant assumptions can be derived primarily from or corroborated by observable data in the market.

The Company enters interest rate lock commitments with customers who apply for a loan which the Company intends to sell to a correspondent lender. The interest rate loan contract ends when the loan closes or the customer withdraws their application. Fair value of the interest rate loan contract is based upon the correspondent lender’s pricing quotes at the report date. Fair value is adjusted for the estimated probability of the loan closing with the borrower. At the time the Company enters into an interest rate loan contract with a customer, it also enters into a best efforts forward sales commitment with the correspondent lender. If the loan has been closed and funded, the best efforts commitment converts to a mandatory forward sales commitment. Fair value is based on the gain or loss that would occur if the Company were to pair-off the transaction with the investor at the measurement date.

Noninterest revenue streams such as service charges on deposit accounts, other service charges and fees, credit and debit card fees, trust income, and annuity and insurance commissions are recognized in accordance with ASC Topic 606, 606 not 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 safe 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 merchant services income. Interchange fees are earned whenever the Company’s debit and credit cards are processed through card payment networks such as Visa and MasterCard. Merchant services income mainly represents commission fees based upon merchant processing volume. The Company’s performance obligation for interchange fee income and merchant services income are largely satisfied, and related revenue recognized, when the services are rendered or upon completion. Payment is typically received immediately or in the following month. In compliance with Topic 606, Trust Income Trust income is primarily comprised of fees earned from the management and administration of trusts and estates 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. OREO Gains and Losses The Company records a gain or loss from the sale of OREO when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. When the Company finances the sale of OREO to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. The following presents noninterest income, segregated by revenue streams in-scope and out-of-scope of Topic 606, December 31, 2022 2021.

Accounting Policies [Abstract]
Cash and Cash Equivalents, Policy [Policy Text Block]	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 [Policy Text Block]	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.
Marketable Securities, Policy [Policy Text Block]	Securities Certain debt securities that management has the positive intent and ability to hold to maturity may not The Company follows the accounting guidance related to recognition and presentation of other–than-temporary impairment (“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.
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. Loans that management has the intent and ability to hold for the foreseeable future, or until maturity or payoff, 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 Bank’s loan policy is updated and approved by the Board of Directors annually and disseminated to lending and loan portfolio management personnel to ensure consistent lending practices. The policy communicates the Company’s risk tolerance by prescribing underwriting guidelines and procedures, including approval limits and hierarchy, documentation standards, requirements for collateral and loan-to-value limits, debt coverage, overall creditworthiness and guarantor support. Of primary consideration is the repayment ability of the borrowers and (if secured) the collateral value in relation to the principal balance. Collateral lowers risk and may The Company’s loans are grouped into six Real Estate Construction Loans. may not may may Consumer Real Estate Loans. first 80% 43% Consumer real estate mortgages may fifth Home equity loans are secured primarily by second 80% not We do not may Commercial Real Estate Loans. first 80% 115% may may Commercial Non Real Estate Loans. 60% 90% 70% 90 Public Sector and IDA Loans. Consumer Non-Real Estate Loans. TDRs Loan modifications are reviewed at the time of modification to determine whether the loan should be designated as TDR. When the Company grants a concession to a borrower for economic or legal reasons related to a borrower’s financial condition, the loan is classified as a TDR. When the Company grants a subsequent modification to a loan that had previously been modified but not may may one Past due status and nonaccrual designation A loan is considered past due when a payment of principal and/or interest is due but not not 30 not not 30 89 90 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 days delinquent unless the credit is well secured and in the process of collection. Loans modified to provide relief from payments of interest or principle for more than 90 Loans in nonaccrual are reviewed on an individual loan basis to determine whether they may not may six Charge-off policy 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 may may
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Allowance for Loan Losses The allowance for loan losses is an estimate of probable losses inherent in the loan portfolio. The allowance is funded by the provision for loan losses, reduced by charge-offs of loans and increased by recoveries of previously charged-off loans. The determination of the allowance is based on two 450 20 310 10 The Company 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 ("collectively evaluated loans"). Impaired loans Impaired loans are larger non-homogeneous loans for which there is a probability that collection of principal or interest will not not Impaired loan measurement methods Impaired loans are individually evaluated to determine appropriate reserves and are measured at the lower of the invested amount or the fair value. Fair value of impaired loans is estimated by either the present value of the loan’s expected future cash flows (“cash flow method”) or the estimated fair value, less selling costs, of the underlying collateral (“collateral method”). Cash flow method: The cash flow method is applied to loans that are not may 90 Collateral method: The collateral method is applied to impaired loans that are collateral-dependent, for which foreclosure is imminent or for which non-collateral repayment sources are determined not may Impaired loans secured by residential 1 4 1 4 third Appraisals must conform to the Uniform Standards of Professional Appraisal Practice and are prepared by an independent third may Evaluations are prepared by third third Updated appraisals or evaluations are ordered when a loan becomes impaired if the appraisal or evaluation on file is more than 24 may not may Results of fair value measurement The estimated fair value is compared with the loan’s recorded investment (unpaid principal net of any interest payments made during the nonaccrual period and net of any partial charge-offs, accrued interest and deferred fees and costs). Any amount of recorded investment that exceeds estimated fair value on collateral-dependent loans, as well as any other impairment loss considered uncollectible, is charged against the allowance for loan losses. Fair value shortfalls that are not not no not Nonaccrual status of impaired loans Nonaccrual status is applied to impaired loans that are not 90 six may Collectively evaluated loans 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 historical loss rates, credit quality indicators, and qualitative factors. Loss rates Loss rates are calculated for and applied to individual classes by averaging loss rates over the most recent eight 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”). Net charge-offs in both calculations include charge-offs and recoveries for all loans within the class, including classified and non-classified loans, as well as impaired and TDR loans. Class historical loss rates are applied to collectively evaluated pass-rated loan balances and special mention rated loan balances, and classified historical loss rates are applied to collectively evaluated classified loan balances. Credit quality indicators Credit quality indicators, which the Company terms risk grades, are assigned through the Company’s credit review function for larger loans and selective review of loans that fall below credit review thresholds. Credit quality is rated based on the loan’s payment history, the borrower’s current financial situation and value of the underlying collateral. Loans that do not 75 75 Qualitative factor allocations The analysis of certain factors results in standard allocations to all classes. These factors include the risk from changes in lending policies, loan officers’ experience, changes in loan review, and economic factors including local unemployment levels, local bankruptcy rates, interest rate environment, and competition/legal/regulatory environments. Standard allocations for residential vacancy rates and housing inventory are applied to all real-estate secured classes and state and political subdivision loans. Qualitative factors incorporate economic data targeted to the Company’s market. If market–specific information is not may 2021, 19 not 2022. Factors analyzed for each class, with resultant allocations based upon the level of risk assessed for each class, include 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. High risk loans include junior liens, interest only and high loan to value loans. High risk loans within each class are analyzed and allocated additional reserves based on current trends. Allocations for qualitative factors are determined for pass-rated loans. To reflect the increased risk of criticized assets, qualitative factor allocations are multiplied by 150% for special mention loans, and multiplied by 200% for classified loans. Sales, purchases and reclassification of loans The Company finances consumer real estate mortgages under “best efforts” contracts with mortgage purchasers. The mortgages are designated as held for sale upon initiation. There have been no not Occasionally, the Company purchases or sells participations in loans. All participation loans purchased met the Company’s normal underwriting standards at the time the participation was entered. Participation loans are included in the appropriate portfolio balances to which the allowance methodology is applied. Unallocated surplus In addition to funding the allowance for loan losses based upon data analysis, the Company has the option to fund an unallocated surplus in excess to the calculated requirement, based upon management judgement. The Company’s policy permits an unallocated surplus of between 0% and 5% of the calculated requirement. Estimation of the allowance for loan losses The estimation of the allowance involves analysis of internal and external variables, methodologies, assumptions and management’s judgment and experience. Key judgments used in determining the allowance for loan losses include internal risk rating determinations, market and collateral values, discount rates, loss rates, and management’s assessment of current economic conditions. These judgments are inherently subjective and actual losses could be greater or less than the estimate. Future estimates of the allowance could increase or decrease based on changes in the financial condition of individual borrowers, concentrations of various types of loans, economic conditions or the markets in which collateral may 5
Rate Lock Commitments [Policy Text Block]	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 to 60 days. The Company protects itself from changes in interest rates through the use of best efforts forward delivery commitments, by committing to sell a loan at the time the borrower commits to an interest rate with the intent that the buyer has assumed interest rate risk on the loan. As a result, the Company is not The market value of rate lock commitments and best efforts contracts is not not no
Property, Plant and Equipment, Policy [Policy Text Block]	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 years for premises, 3-10 years for furniture and equipment, and 3 years for computer software. Costs of maintenance and repairs are charged to expense as incurred and improvements are capitalized.
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. Goodwill is subject to at least an annual assessment for impairment by applying a fair value based test. The Company contracts with a third September 30 2022 September 30, 2022.

Pension and Other Postretirement Plans, Pensions, Policy [Policy Text Block]	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 other comprehensive loss. The funded status of a benefit plan is measured as the difference between plan assets at fair value and the projected benefit obligation. The Company’s actuary determines plan obligations and annual pension expense using a number of key assumptions, including the discount rate, the estimated return on plan assets and the anticipated rate of compensation increases. Changes in these assumptions in the future, if any, or in the method under which benefits are calculated may

NBB’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.
