Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation and Consolidation. The consolidated financial statements include the accounts of Emclaire Financial Corp (the Corporation) and its wholly owned subsidiary, The Farmers National Bank of Emlenton (the Bank ). All significant intercompany balances and transactions have been eliminated in consolidation.
Nature of Operations [Policy Text Block]	Nature of Operations. The Corporation provides a variety of financial services to individuals and businesses through its offices in Pennsylvania and West Virginia. Its primary deposit products are checking, savings and term certificate accounts and its primary lending products are residential and commercial mortgages, commercial business loans and consumer loans.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates and Classifications. In preparing consolidated financial statements in conformity with U.S. generally accepted accounting principles (GAAP), management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Certain amounts previously reported may have been reclassified to conform to the current year financial statement presentation. Such reclassifications did not affect net income or stockholders' equity. Additionally, the global spread of the coronavirus resulted in business and social disruption and was declared a Public Health Emergency of International Concern by the World Health Organization. The operations and business results of the Corporation could be materially adversely effected. Significant estimates as disclosed in Note 1, including the allowance for loan losses, valuation of financial instruments and the carrying of goodwill may be materially adversely impacted by national and local events designed to contain the coronavirus.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Significant Group Concentrations of Credit Risk. Most of the Corporation's activities are with customers located within the Western Pennsylvania region of the country. Note 2 discusses the type of securities that the Corporation invests in. Note 3 discusses the types of lending the Corporation engages in. The Corporation does not have any significant concentrations to any one industry or customer.
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 on hand, cash items, interest-earning deposits with other financial institutions and federal funds sold and due from correspondent banks. Interest-earning deposits are generally short-term in nature and are carried at cost. Federal funds are generally sold or purchased for one day periods. Net cash flows are reported for loan and deposit transactions and short-term borrowings.
Restrictions on Dividends [Policy Text Block]	Dividend Restrictions. Banking r egulations require maintaining certain capital levels and may limit the dividends paid by the Bank to the Corporation or by the Corporation to stockholders.
Marketable Securities, Policy [Policy Text Block]	Securities Available for Sale. Debt securities are classified as available for sale when they might be sold before maturity. Debt securities available for sale are carried at fair value, with unrealized holding gains and losses reported in other comprehensive income, net of tax. Interest income from securities includes amortization of purchase premium or discount. Discounts on securities are accreted using the level yield method through the maturity date. Premiums are amortized using the level yield method through the first call date. In the absence of a call date, the premium is amortized through the maturity date. Gains and losses on sales are recorded on the trade date and determined using the specific identification method. Management evaluates debt securities for other-than-temporary impairment (OTTI) at least on a quarterly basis, and more frequently when economic, market or other concerns warrant such evaluation. Consideration is given to: ( 1 ) the length of time and the extent to which the fair value has been less than cost, ( 2 ) the financial condition and near term prospects of the issuer, ( 3 ) whether the market decline was affected by macroeconomic conditions and ( 4 ) whether the Corporation has the intent to sell the security or more likely than not will be required to sell the security before the recovery of its amortized cost basis. If the Corporation intends to sell an impaired security, or if it is more likely than not the Corporation will be required to sell the security before its anticipated recovery, the Corporation records an other-than-temporary loss in an amount equal to the entire difference between fair value and amortized cost through earnings. Otherwise, only the credit portion of the estimated loss on debt securities is recognized in earnings, with the other portion of the loss recognized in other comprehensive income.
Equity Securities [Policy Text Block]	Equity Securities. Equity securities are carried at fair value. The holding gains or losses are reported in net income.
Financing Receivable [Policy Text Block]	Loans Receivable . The Corporation grants mortgage, commercial and consumer loans to customers. A substantial portion of the loan portfolio is represented by loans collateralized by real estate primarily located throughout Western Pennsylvania. The ability of the Corporation's debtors to honor their contracts is dependent upon real estate and general economic conditions in this area. 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 charge-offs, the allow ance for loan losses, and any deferred fees or costs on originated loans or premiums or discounts on purchased loans. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, and premiums and discounts are deferred and recognized in interest income as an adjustment of the related loan yield using the interest method. The accrual of interest on all classes of loans is typically discontinued at the time the loan is 90 days past due unless the credit is well secured and in the process of collection. At 120 days past due, all loans are considered nonaccrual. Loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. Nonaccrual loans and loans past due 90 days still on accrual include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified as impaired loans. All interest accrued but not collected for loans that are placed on nonaccrual status or charged-off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for a return to accrual status. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Allowance for Loan Losses. The allowance for loan losses is established for probable incurred credit losses through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are typically credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based upon management's periodic review of the collectability of loans in light of historic experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower's ability to repay, estimated value of any underlying collateral, prevailing economic conditions and other factors. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. A loan is considered impaired when, based on current information and events, it is probable that the Corporation will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Loans for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings (TDR) and classified as impaired. Factors considered by management in determining impairment on all loan classes include demonstrated ability to repay, payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower's prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan by loan basis for commercial loans by either the present value of expected future cash flows discounted at the loans effective interest rate, the loan's obtainable market price, or the fair value of the collateral if the loan is collateral dependent. Large groups of small balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Corporation does not separately identify individual consumer and residential mortgage loans for impairment disclosures, unless such loans are the subject of a restructuring agreement. TDRs are separately identified for impairment disclosures and are measured at the present value of estimated future cash flows using the loan's effective rate at inception. If a TDR is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of collateral. For TDRs that subsequently default, the Corporation determines the amount of reserves in accordance with accounting policies for the allowance for loan losses. The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. The general component covers non-impaired loans and is based on historical loss experience adjusted for qualitative factors. The historical loss experience is determined by portfolio segment and is based on the actual loss history experienced by the Corporation over the prior 12 quarters. Qualitative factors considered by management include national and local economic and business conditions, changes in the nature and volume of the loan portfolio, quality of loan review systems, and changes in trends, volume and severity of past due, nonaccrual and classified loans, and loss and recovery trends. The Corporation's portfolio segments are as follows: Residential mortgages: Residential mortgage loans are loans to consumers utilized for the purchase, refinance or construction of a residence. Changes in interest rates or market conditions may impact a borrower's ability to meet contractual principal and interest payments. Home equity loans and lines of credit: Home equity loans and lines of credit are credit facilities extended to homeowners who wish to utilize the equity in their property in order to borrow funds for almost any consumer purpose. Property values may fluctuate due to economic and other factors. Commercial real estate: Commercial real estate loans are subject to underwriting standards and processes similar to commercial loans. These loans are viewed primarily as cash flow loans and the repayment of these loans is largely dependent on the successful operation of the property. Loan performance may be adversely affected by factors impacting the general economy or conditions specific to real estate markets such as geographic location and property type. Commercial business: Commercial credit is extended to business customers for use in normal operations to finance working capital needs, equipment purchases or other projects. The majority of these borrowers are customers doing business within our geographic region. These loans are generally underwritten individually and secured with the assets of the company and the personal guarantee of the business owners. Commercial loans are made based primarily on the historical and projected cash flow of the borrower and the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not behave as forecasted and collateral securing loans may fluctuate in value due to economic or individual performance factors. Consumer: Consumer loans are loans to an individual for non-business purposes such as automobile purchases or debt consolidation. These loans are originated based primarily on credit scores and debt-to-income ratios which may be adversely affected by economic or individual performance factors.
Financing Receivable, Held-for-sale [Policy Text Block]	Loans Held for Sale. Mortgage loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or fair value, as determined by outstanding commitments from investors. Net unrealized losses, if any, are recorded as a valuation allowance and charged to earnings. Mortgage loans held for sale are generally sold with servicing retained. The carrying value of mortgage loans sold is reduced by the amount allocated to the servicing right. Gains and losses on sales of mortgages are based on the difference between the selling price and the carrying value of the related loan sold.
Federal Bank Stocks [Policy Text Block]	Federal Bank Stocks. The Bank is a member of the Federal Home Loan Bank of Pittsburgh (FHLB) and the Federal Reserve Bank of Cleveland (FRB). As a member of these federal banking systems, the Bank maintains an investment in the capital stock of the respective regional banks. These stocks are held at cost and classified as restricted stock. These stocks are purchased and redeemed at par as directed by the federal banks and levels maintained are based primarily on borrowing and other correspondent relationships. These stocks are periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income.
Bank Owned Life Insurance [Policy Text Block]	Bank-Owned Life Insurance (BOLI). The Bank purchased life insurance policies on certain key officers and employees. BOLI is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
Property, Plant and Equipment, Policy [Policy Text Block]	Premises and Equipment . Land is carried at cost. Premises, furniture and equipment, and leasehold improvements are carried at cost less accumulated depreciation or amortization. Depreciation is calculated on a straight-line basis over the estimated useful lives of the related assets, which are twenty-five years to forty years for buildings and three to ten years for furniture and equipment. Amortization of leasehold improvements is computed using the straight-line method over the shorter of their estimated useful life or the expected term of the leases. Expected terms include lease option periods to the extent that the exercise of such option is reasonably assured. Premises and equipment are reviewed for impairment when events indicate their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, assets are recorded at fair value.
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill and Intangible Assets . Goodwill results from business acquisitions and represents the excess of the purchase price over the fair value of acquired assets and liabilities. Core deposit intangible assets arise from whole bank or branch acquisitions and are measured at fair value and then are amortized over their estimated useful lives. Goodwill is not amortized but is assessed at least annually for impairment, and more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value below the carrying amount. An initial qualitative evaluation is made to assess the likelihood of impairment and determine whether further quantitative testing to calculate the fair value is necessary. When the qualitative evaluation indicates that impairment is more likely than not, quantitative testing is required whereby the fair value of each reporting unit is calculated and compared to the recorded book value. If the calculated fair value of the reporting unit exceeds its carrying value, goodwill is not considered impaired. In the event of an impairment, any such charges is recognized as a deduction from earnings in the period identified in an amount equal to the difference. The Corporation performs an annual assessment as of November 30 each year. Goodwill is the only intangible asset with an indefinite life on the Corporation's balance sheet.
Transfers and Servicing of Financial Assets, Servicing of Financial Assets, Policy [Policy Text Block]	Servicing Assets. Servicing assets represent the allocated value of retained servicing rights on loans sold. Servicing assets are expensed in proportion to, and over the period of, estimated net servicing revenues. Impairment is evaluated based on the fair value of the assets, using groupings of the underlying loans as to interest rates. Fair value is determined using prices for similar assets with similar characteristics, when available, or based upon discounted cash flows using market-based assumptions. Any impairment of a grouping is reported as a valuation allowance, to the extent that fair value is less than the capitalized amount for a grouping. At December 31, 2020 and 2019, the outstanding balance of loans serviced for other totaled $26.8 million and $32.8 million, respectively, and are not included in the accompanying consolidated balance sheet. At December 31, 2020 and 2019, the mortgage servicing rights associated with these outstanding balances were $165,000 and $211,000, respectively, and are included with other assets in the consolidated balance sheet. In addition, for the years ended December 31, 2020 and 2019, the Corporation recognized $80,000 and $85,000, respectively, for the servicing of these loans and is recorded in other noninterest income,.
Financing Receivable, Real Estate Acquired Through Foreclosure [Policy Text Block]	Other Real Estate Acquired Through Foreclosure (OREO). Real estate properties acquired through foreclosure are initially recorded at fair value less cost to sell when acquired, thereby establishing a new cost basis for the asset. These assets are subsequently accounted for at the lower of carrying amount or fair value less cost to sell. If fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Revenue and expenses from operations of the properties, gains and losses on sales and additions to the valuation allowance are included in operating results. Real estate acquired through foreclosure is classified in prepaid expenses and other assets and totaled $344,000 and $249,000 at December 31, 2020 and 2019, respectively. Loans secured by residential real estate properties for which formal foreclosure proceedings are in process totaled $ 1.3 million and $545,000 at December 31, 2020 and 2019, respectively.
Treasury Stock [Policy Text Block]	Treasury Stock. Common stock purchased for treasury is recorded at cost. At the date of subsequent reissue, the treasury stock account is reduced by the cost of such stock on the first -in, first -out basis.
Income Tax, Policy [Policy Text Block]	Income Taxes. Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Corporation recognizes interest and/or penalties related to income tax matters in income tax expense.
Earnings Per Share, Policy [Policy Text Block]	Earnings Per Common Share (EPS). Basic EPS excludes dilution and is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted EPS includes the dilutive effect of additional potential common shares issuable under stock options and restricted stock awards.
Comprehensive Income, Policy [Policy Text Block]	Comprehensive Income. Comprehensive income includes net income and other comprehensive income (loss). Other comprehensive income (loss) is comprised of unrealized holding gains and losses on securities available for sale and changes in the funded status of pension which are also recognized as separate components of equity.
Segment Reporting, Policy [Policy Text Block]	Operating Segments. Operations are managed and financial performance is evaluated on a corporate-wide basis. Accordingly, all financial services operations are considered by management to be aggregated in one reportable operating segment.
Postemployment Benefit Plans, Policy [Policy Text Block]	Retirement Plans. The Corporation maintains a noncontributory defined benefit plan covering eligible employees and officers. Effective January 1, 2009 the plan was closed to new participants. The Corporation provided the requisite notice to plan participants on March 12, 2013 of the determination to freeze the plan (curtailment). Therefore, employees ceased to earn benefits as of January 1, 2013. This amendment to the plan did not affect benefits earned by the participant prior to the date of the freeze. The Corporation also maintains a 401 (k) plan, which covers substantially all employees, and a supplemental executive retirement plan for key executive officers.
Share-based Payment Arrangement [Policy Text Block]	Stock Compensation Plans. Compensation expense is recognized for stock options and restricted stock awards issued based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Corporation's common stock at the date of grant is used for restricted stock awards. Compensation expense is recognized over the required service period, generally defined as the vesting period. It is the Corporation's policy to issue shares on the vesting date for restricted stock awards. Unvested restricted stock awards do not receive dividends declared by the Corporation.
Transfers of Financial Assets [Policy Text Block]	Transfers of Financial Assets. Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when ( 1 ) the assets have been isolated from the Corporation, ( 2 ) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and ( 3 ) the Corporation does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Off-Balance-Sheet Credit Exposure, Policy [Policy Text Block]	Off-Balance Sheet Financial Instruments . In the ordinary course of business, the Corporation has entered into off-balance sheet financial instruments consisting of commitments to extend credit, commitments under line of credit lending arrangements and letters of credit. Such financial instruments are recorded in the financial statements when they are funded.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Value of Financial Instruments . Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect these estimates.
Commitments and Contingencies, Policy [Policy Text Block]	Loss Contingencies. Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there currently are such matters that will have a material effect on the financial statements.
New Accounting Pronouncements, Policy [Policy Text Block]	Newly Issued Not Yet Effective Accounting Standards. In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016 - 13, “Financial Instruments - Credit Losses (Topic 326 ): Measurement of Credit Losses on Financial Instruments”. ASU 2016 - 13 significantly changes the way impairment of financial instruments is recognized by requiring immediate recognition of estimated credit losses expected to occur over the remaining life of the financial instruments. The main provisions of the guidance include ( 1 ) replacing the “incurred loss” approach under current GAAP with an “expected loss” model for instruments measured at amortized cost, ( 2 ) requiring entities to record an allowance for available-for-sale debt securities rather than reduce the carrying amount of the investments, as is required by the other-than-temporary impairment model under current GAAP, and ( 3 ) a simplified accounting model for purchased credit-impaired debt securities and loans. The ASU was originally effective for interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. However, on October 16, 2019, FASB announced a delay for the effective date of this ASU for smaller reporting companies until fiscal years beginning after December 15, 2022. As the Corporation is a smaller reporting company, the delay would be applicable. Management has selected a software vendor and is currently working through the implementation process. The Corporation is reviewing available historical information in order to assess the expected credit losses and determine the impact the adoption of ASU 2016 - 13 will have on the financial statements. In August 2018, the FASB issued ASU 2018 - 14, "Compensation - Retirement Benefits - Defined Benefit Plans". ASU 2018 - 14 removes disclosures pertaining to (a) the amounts of AOCI expected to be recognized as pension costs over the next fiscal year, (b) the amount and timing of plan assets expected to be returned to the employer, and (c) the effect of one -percentage-point change in the assumed health care trends on (i) service and interest costs and (ii) post-retirement health care benefit obligation. A disclosure will be added requiring an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. The amendments in this update are effective retrospectively for annual periods and interim periods within those annual periods beginning after December 15, 2020. The Corporation does not expect ASU 2018 - 14 to have a material impact on its financial statements and disclosures. In December 2019, the FASB issued ASU 2019 - 12, "Income Taxes - Simplifying the Accounting for Income Taxes". ASU 2019 - 12 is effective for fiscal years beginning after December 15, 2020. Certain provisions under ASU 2019 - 12 require prospective application, some require modified retrospective adoption, while other provisions require retrospective application to all periods presented in the consolidated financial statements upon adoption. The Corporation is currently evaluating the effect that this ASU will have on its financial statements and disclosures. In March 2020, the FASB issued ASU 2020 - 04, "Reference Rate Reform". ASU 2020 - 04 contains optional guidance to ease the potential burden in accounting for, or recognizing the effects from, reference rate reform on financial reporting. The new standard is a result of the London Interbank Offered Rate (LIBOR) likely being discontinued as a benchmark rate. The standard is elective and provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, or other transactions that reference LIBOR, or another reference rate that may be discontinued. This ASU became effective upon issuance and generally can be applied through December 31, 2022. The Corporation has identified fourteen purchased participation loans totaling $40.4 million in outstanding balances and two tax-exempt commercial business loans totaling $2.5 million in outstanding balances tied to the LIBOR reference rate. The Corporation has not yet made any contract modifications related to the outstanding loans, however, does not expect any changes to have a material impact on financial statements or disclosures. Adoption of New Accounting Policies. In January 2017, the FASB issued ASU 2017 - 04, "Simplifying the Test for Goodwill Impairment". This ASU simplifies the measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Instead, under this amendment, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss should not exceed the total amount of goodwill allocated to that reporting unit. The Corporation has goodwill from prior business combinations and performs an annual impairment test or more frequently if changes or circumstances occur that would more likely than not reduce the fair value of the reporting unit below its carrying value. ASU 2017 - 04 was effective on January 1, 2020 and the adoption did not have a material impact on the Corporation's financial statement disclosures. In August 2018, the FASB issued ASU 2018 - 13, "Fair Value Measurement". ASU 2018 - 13 eliminates, adds and modifies certain disclosure requirements for fair value measurements. Disclosures for transfers between Level 1 and Level 2, the policy for timing of transfers between levels, and the valuation processes for Level 3 fair value measurement were removed. Additional disclosures were required relating to (a) changes in unrealized gains/losses in OCI for Level 3 fair value measurements for assets held at the end of the reporting period, and (b) the process of calculating weighted average for significant unobservable inputs used to develop Level 3 fair value measurements. ASU 2018 - 03 was effective on January 1, 2020 and the adoption did not have a material impact on the Corporation's financial statement disclosures.

Equity Securities [Policy Text Block]

Equity Securities.

Equity securities are carried at fair value. The holding gains or losses are reported in net income.

Financing Receivable [Policy Text Block]

Loans Receivable

The Corporation grants mortgage, commercial and consumer loans to customers. A substantial portion of the loan portfolio is represented by loans collateralized by real estate primarily located throughout Western Pennsylvania. The ability of the Corporation's debtors to honor their contracts is dependent upon real estate and general economic conditions in this area.

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 charge-offs, the allow

ance for loan losses, and any deferred fees or costs on originated loans or premiums or discounts on purchased loans. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, and premiums and discounts are deferred and recognized in interest income as an adjustment of the related loan yield using the interest method.

The accrual of interest on all classes of loans is typically discontinued at the time the loan is

days past due unless the credit is well secured and in the process of collection. At

120

days past due, all loans are considered nonaccrual. Loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. Nonaccrual loans and loans past due

days still on accrual include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified as impaired loans. All interest accrued but

not

collected for loans that are placed on nonaccrual status or charged-off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for a return to accrual status. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]

Allowance for Loan Losses.

The allowance for loan losses is established for probable incurred credit losses through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are typically credited to the allowance.

The allowance for loan losses is evaluated on a regular basis by management and is based upon management's periodic review of the collectability of loans in light of historic experience, the nature and volume of the loan portfolio, adverse situations that

may

affect the borrower's ability to repay, estimated value of any underlying collateral, prevailing economic conditions and other factors. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.

A loan is considered impaired when, based on current information and events, it is probable that the Corporation will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Loans for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings (TDR) and classified as impaired.

Factors considered by management in determining impairment on all loan classes include demonstrated ability to repay, payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are

not

classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower's prior payment record, and the amount of the shortfall in relation to the principal and interest owed.

Impairment is measured on a loan by loan basis for commercial loans by either the present value of expected future cash flows discounted at the loans effective interest rate, the loan's obtainable market price, or the fair value of the collateral if the loan is collateral dependent. Large groups of small balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Corporation does

not

separately identify individual consumer and residential mortgage loans for impairment disclosures, unless such loans are the subject of a restructuring agreement.

TDRs are separately identified for impairment disclosures and are measured at the present value of estimated future cash flows using the loan's effective rate at inception. If a TDR is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of collateral. For TDRs that subsequently default, the Corporation determines the amount of reserves in accordance with accounting policies for the allowance for loan losses.

The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. The general component covers non-impaired loans and is based on historical loss experience adjusted for qualitative factors. The historical loss experience is determined by portfolio segment and is based on the actual loss history experienced by the Corporation over the prior

quarters. Qualitative factors considered by management include national and local economic and business conditions, changes in the nature and volume of the loan portfolio, quality of loan review systems, and changes in trends, volume and severity of past due, nonaccrual and classified loans, and loss and recovery trends. The Corporation's portfolio segments are as follows:

Residential mortgages:

Residential mortgage loans are loans to consumers utilized for the purchase, refinance or construction of a residence. Changes in interest rates or market conditions

may

impact a borrower's ability to meet contractual principal and interest payments.

Home equity loans and lines of credit:

Home equity loans and lines of credit are credit facilities extended to homeowners who wish to utilize the equity in their property in order to borrow funds for almost any consumer purpose. Property values

may

fluctuate due to economic and other factors.

Commercial real estate:

Commercial real estate loans are subject to underwriting standards and processes similar to commercial loans. These loans are viewed primarily as cash flow loans and the repayment of these loans is largely dependent on the successful operation of the property. Loan performance

may

be adversely affected by factors impacting the general economy or conditions specific to real estate markets such as geographic location and property type.

Commercial business:

Commercial credit is extended to business customers for use in normal operations to finance working capital needs, equipment purchases or other projects. The majority of these borrowers are customers doing business within our geographic region. These loans are generally underwritten individually and secured with the assets of the company and the personal guarantee of the business owners. Commercial loans are made based primarily on the historical and projected cash flow of the borrower and the underlying collateral provided by the borrower. The cash flows of borrowers, however,

may

not

behave as forecasted and collateral securing loans

may

fluctuate in value due to economic or individual performance factors.

Consumer:

Consumer loans are loans to an individual for non-business purposes such as automobile purchases or debt consolidation. These loans are originated based primarily on credit scores and debt-to-income ratios which

may

be adversely affected by economic or individual performance factors.

Financing Receivable, Held-for-sale [Policy Text Block]

Loans Held for Sale.

Mortgage loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or fair value, as determined by outstanding commitments from investors. Net unrealized losses, if any, are recorded as a valuation allowance and charged to earnings. Mortgage loans held for sale are generally sold with servicing retained. The carrying value of mortgage loans sold is reduced by the amount allocated to the servicing right. Gains and losses on sales of mortgages are based on the difference between the selling price and the carrying value of the related loan sold.

Federal Bank Stocks [Policy Text Block]

Federal Bank Stocks.

The Bank is a member of the Federal Home Loan Bank of Pittsburgh (FHLB) and the Federal Reserve Bank of Cleveland (FRB). As a member of these federal banking systems, the Bank maintains an investment in the capital stock of the respective regional banks. These stocks are held at cost and classified as restricted stock. These stocks are purchased and redeemed at par as directed by the federal banks and levels maintained are based primarily on borrowing and other correspondent relationships. These stocks are periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income.

Bank Owned Life Insurance [Policy Text Block]

Bank-Owned Life Insurance (BOLI).

The Bank purchased life insurance policies on certain key officers and employees. BOLI is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.

Property, Plant and Equipment, Policy [Policy Text Block]

Premises and Equipment

Land is carried at cost. Premises, furniture and equipment, and leasehold improvements are carried at cost less accumulated depreciation or amortization. Depreciation is calculated on a straight-line basis over the estimated useful lives of the related assets, which are

twenty-five

years to

forty

years for buildings and

three

ten

years for furniture and equipment. Amortization of leasehold improvements is computed using the straight-line method over the shorter of their estimated useful life or the expected term of the leases. Expected terms include lease option periods to the extent that the exercise of such option is reasonably assured. Premises and equipment are reviewed for impairment when events indicate their carrying amount

may

not

be recoverable from future undiscounted cash flows. If impaired, assets are recorded at fair value.

Goodwill and Intangible Assets, Policy [Policy Text Block]

Goodwill and Intangible Assets

Goodwill results from business acquisitions and represents the excess of the purchase price over the fair value of acquired assets and liabilities. Core deposit intangible assets arise from whole bank or branch acquisitions and are measured at fair value and then are amortized over their estimated useful lives. Goodwill is

not

amortized but is assessed at least annually for impairment, and more frequently if an event occurs or circumstances change that would more likely than

not

reduce the fair value below the carrying amount. An initial qualitative evaluation is made to assess the likelihood of impairment and determine whether further quantitative testing to calculate the fair value is necessary. When the qualitative evaluation indicates that impairment is more likely than

not,

quantitative testing is required whereby the fair value of each reporting unit is calculated and compared to the recorded book value. If the calculated fair value of the reporting unit exceeds its carrying value, goodwill is

not

considered impaired. In the event of an impairment, any such charges is recognized as a deduction from earnings in the period identified in an amount equal to the difference. The Corporation performs an annual assessment as of

November 30

each year. Goodwill is the only intangible asset with an indefinite life on the Corporation's balance sheet.

Transfers and Servicing of Financial Assets, Servicing of Financial Assets, Policy [Policy Text Block]

Servicing Assets.

Servicing assets represent the allocated value of retained servicing rights on loans sold. Servicing assets are expensed in proportion to, and over the period of, estimated net servicing revenues. Impairment is evaluated based on the fair value of the assets, using groupings of the underlying loans as to interest rates. Fair value is determined using prices for similar assets with similar characteristics, when available, or based upon discounted cash flows using market-based assumptions. Any impairment of a grouping is reported as a valuation allowance, to the extent that fair value is less than the capitalized amount for a grouping. At

December 31, 2020

and

2019,

the outstanding balance of loans serviced for other totaled

$26.8

million and

$32.8

million, respectively, and are

not

included in the accompanying consolidated balance sheet. At

December 31, 2020

and

2019,

the mortgage servicing rights associated with these outstanding balances were

$165,000

and

$211,000,

respectively, and are included with other assets in the consolidated balance sheet. In addition, for the years ended

December 31, 2020

and

2019,

the Corporation recognized

$80,000

and

$85,000,

respectively, for the servicing of these loans and is recorded in other noninterest income,.

Financing Receivable, Real Estate Acquired Through Foreclosure [Policy Text Block]

Other Real Estate Acquired Through Foreclosure (OREO).

Real estate properties acquired through foreclosure are initially recorded at fair value less cost to sell when acquired, thereby establishing a new cost basis for the asset. These assets are subsequently accounted for at the lower of carrying amount or fair value less cost to sell. If fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Revenue and expenses from operations of the properties, gains and losses on sales and additions to the valuation allowance are included in operating results. Real estate acquired through foreclosure is classified in prepaid expenses and other assets and totaled

$344,000

and

$249,000

December

31,

2020

and

2019,

respectively. Loans secured by residential real estate properties for which formal foreclosure proceedings are in process totaled $

1.3

million

and

$545,000

December

31,

2020

and

2019,

respectively.

Treasury Stock [Policy Text Block]

Treasury Stock.

Common stock purchased for treasury is recorded at cost. At the date of subsequent reissue, the treasury stock account is reduced by the cost of such stock on the

first

-in,

first

-out basis.

Income Tax, Policy [Policy Text Block]

Income Taxes.

Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. A tax position is recognized as a benefit only if it is “more likely than

not”

that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than

50%

likely of being realized on examination. For tax positions

not

meeting the “more likely than

not”

test,

tax benefit is recorded. The Corporation recognizes interest and/or penalties related to income tax matters in income tax expense.

Earnings Per Share, Policy [Policy Text Block]

Earnings Per Common Share (EPS).

Basic EPS excludes dilution and is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted EPS includes the dilutive effect of additional potential common shares issuable under stock options and restricted stock awards.

Comprehensive Income, Policy [Policy Text Block]

Comprehensive Income.

Comprehensive income includes net income and other comprehensive income (loss). Other comprehensive income (loss) is comprised of unrealized holding gains and losses on securities available for sale and changes in the funded status of pension which are also recognized as separate components of equity.

Segment Reporting, Policy [Policy Text Block]

Operating Segments.

Operations are managed and financial performance is evaluated on a corporate-wide basis. Accordingly, all financial services operations are considered by management to be aggregated in

one

reportable operating segment.

Postemployment Benefit Plans, Policy [Policy Text Block]

Retirement Plans.

The Corporation maintains a noncontributory defined benefit plan covering eligible employees and officers. Effective

January 1, 2009

the plan was closed to new participants. The Corporation provided the requisite notice to plan participants on

March 12, 2013

of the determination to freeze the plan (curtailment). Therefore, employees ceased to earn benefits as of

January 1, 2013.

This amendment to the plan did

not

affect benefits earned by the participant prior to the date of the freeze. The Corporation also maintains a

401

(k) plan, which covers substantially all employees, and a supplemental executive retirement plan for key executive officers.

Share-based Payment Arrangement [Policy Text Block]

Stock Compensation Plans.

Compensation expense is recognized for stock options and restricted stock awards issued based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Corporation's common stock at the date of grant is used for restricted stock awards. Compensation expense is recognized over the required service period, generally defined as the vesting period. It is the Corporation's policy to issue shares on the vesting date for restricted stock awards. Unvested restricted stock awards do

not

receive dividends declared by the Corporation.

Transfers of Financial Assets [Policy Text Block]

Transfers of Financial Assets.

Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (

) the assets have been isolated from the Corporation, (

) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (

) the Corporation does

not

maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.

Off-Balance-Sheet Credit Exposure, Policy [Policy Text Block]

Off-Balance Sheet Financial Instruments

In the ordinary course of business, the Corporation has entered into off-balance sheet financial instruments consisting of commitments to extend credit, commitments under line of credit lending arrangements and letters of credit. Such financial instruments are recorded in the financial statements when they are funded.

Fair Value of Financial Instruments, Policy [Policy Text Block]

Fair Value of Financial Instruments

Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect these estimates.

Commitments and Contingencies, Policy [Policy Text Block]

Loss Contingencies.

Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does

not

believe there currently are such matters that will have a material effect on the financial statements.

New Accounting Pronouncements, Policy [Policy Text Block]

Newly Issued

Not

Yet Effective Accounting Standards.

June 2016,

the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU)

2016

13,

“Financial Instruments - Credit Losses (Topic

326

): Measurement of Credit Losses on Financial Instruments”. ASU

2016

significantly changes the way impairment of financial instruments is recognized by requiring immediate recognition of estimated credit losses expected to occur over the remaining life of the financial instruments. The main provisions of the guidance include (

) replacing the “incurred loss” approach under current GAAP with an “expected loss” model for instruments measured at amortized cost, (

) requiring entities to record an allowance for available-for-sale debt securities rather than reduce the carrying amount of the investments, as is required by the other-than-temporary impairment model under current GAAP, and (

) a simplified accounting model for purchased credit-impaired debt securities and loans. The ASU was originally effective for interim and annual reporting periods beginning after

December 15, 2019,

with early adoption permitted. However, on

October 16, 2019,

FASB announced a delay for the effective date of this ASU for smaller reporting companies until fiscal years beginning after

December 15, 2022.

As the Corporation is a smaller reporting company, the delay would be applicable. Management has selected a software vendor and is currently working through the implementation process. The Corporation is reviewing available historical information in order to assess the expected credit losses and determine the impact the adoption of ASU

2016

will have on the financial statements.

August 2018,

the FASB issued ASU

2018

14,

"Compensation - Retirement Benefits - Defined Benefit Plans". ASU

2018

removes disclosures pertaining to (a) the amounts of AOCI expected to be recognized as pension costs over the next fiscal year, (b) the amount and timing of plan assets expected to be returned to the employer, and (c) the effect of

one

-percentage-point change in the assumed health care trends on (i) service and interest costs and (ii) post-retirement health care benefit obligation. A disclosure will be added requiring an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. The amendments in this update are effective retrospectively for annual periods and interim periods within those annual periods beginning after

December 15, 2020.

The Corporation does

not

expect ASU

2018

to have a material impact on its financial statements and disclosures.

December 2019,

the FASB issued ASU

2019

12,

"Income Taxes - Simplifying the Accounting for Income Taxes". ASU

2019

is effective for fiscal years beginning after

December 15, 2020.

Certain provisions under ASU

2019

require prospective application, some require modified retrospective adoption, while other provisions require retrospective application to all periods presented in the consolidated financial statements upon adoption. The Corporation is currently evaluating the effect that this ASU will have on its financial statements and disclosures.

March 2020,

the FASB issued ASU

2020

04,

"Reference Rate Reform". ASU

2020

contains optional guidance to ease the potential burden in accounting for, or recognizing the effects from, reference rate reform on financial reporting. The new standard is a result of the London Interbank Offered Rate (LIBOR) likely being discontinued as a benchmark rate. The standard is elective and provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, or other transactions that reference LIBOR, or another reference rate that

may

be discontinued. This ASU became effective upon issuance and generally can be applied through

December 31, 2022.

The Corporation has identified

fourteen

purchased participation loans totaling

$40.4

million in outstanding balances and

two

tax-exempt commercial business loans totaling

$2.5

million in outstanding balances tied to the LIBOR reference rate. The Corporation has

not

yet made any contract modifications related to the outstanding loans, however, does

not

expect any changes to have a material impact on financial statements or disclosures.

Adoption of New Accounting Policies.

January 2017,

the FASB issued ASU

2017

04,

"Simplifying the Test for Goodwill Impairment". This ASU simplifies the measurement of goodwill by eliminating Step

from the goodwill impairment test. Instead, under this amendment, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss should

not

exceed the total amount of goodwill allocated to that reporting unit. The Corporation has goodwill from prior business combinations and performs an annual impairment test or more frequently if changes or circumstances occur that would more likely than

not

reduce the fair value of the reporting unit below its carrying value. ASU

2017

was effective on

January 1, 2020

and the adoption did

not

have a material impact on the Corporation's financial statement disclosures.

August 2018,

the FASB issued ASU

2018

13,

"Fair Value Measurement". ASU

2018

eliminates, adds and modifies certain disclosure requirements for fair value measurements. Disclosures for transfers between Level

and Level

the policy for timing of transfers between levels, and the valuation processes for Level

fair value measurement were removed. Additional disclosures were required relating to (a) changes in unrealized gains/losses in OCI for Level

fair value measurements for assets held at the end of the reporting period, and (b) the process of calculating weighted average for significant unobservable inputs used to develop Level

fair value measurements.

ASU

2018

was effective on

January 1, 2020

and the adoption did

not

have a material impact on the Corporation's financial statement disclosures.
