Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Unless otherwise indicated, dollar amounts are in thousands, except per share data. Business and Organization CNB Financial Corporation (the "Corporation") is headquartered in Clearfield, Pennsylvania, and provides a full range of banking and related services through its wholly owned subsidiary, CNB Bank (the "Bank"). In addition, the Bank provides trust and asset management services, including the administration of trusts and estates, retirement plans, and other employee benefit plans as well as a full range of wealth management services. The Bank serves individual and corporate customers and is subject to competition from other financial institutions and intermediaries with respect to these services. In addition to the Bank, the Corporation also operates a consumer discount loan and finance business through its wholly owned subsidiary, Holiday Financial Services Corporation ("Holiday"). The Corporation and its other subsidiaries are subject to examination by federal and state regulators. The Corporation’s market area is primarily concentrated in the central and northwest regions of the Commonwealth of Pennsylvania, the central and northeast regions of the state of Ohio and western New York. Basis of Financial Presentation The financial statements are consolidated to include the accounts of the Corporation and the Bank, CNB Securities Corporation, Holiday, CNB Risk Management, Inc. and CNB Insurance Agency. All significant intercompany accounts and transactions have been eliminated in the consolidated financial statements. Certain prior period amounts have been reclassified to conform to the current period presentation. Reclassifications had no effect on prior year net income or shareholders’ equity. Risks and Uncertainties The worldwide spread of COVID-19 has created significant uncertainty in the global economy. There have been no comparable recent events that provide guidance as to the effect the spread of COVID-19 as a global pandemic may have, and, as a result, the ultimate impact of COVID-19 and the extent to which COVID-19 and the related government actions impact the Corporation’s business, results of operations and financial condition will depend on future developments, which are highly uncertain and difficult to predict. Use of Estimates To prepare financial statements in conformity with U.S. generally accepted accounting principles ("GAAP"), management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided and future results could differ. The Corporation's business is dependent upon the willingness and ability of its employees and customers to conduct banking and other financial transactions. If the global response to contain the COVID-19 pandemic requires further restricted measures or is unsuccessful, the Corporation could experience a material adverse effect on its business, financial condition, results of operations and cash flows. Since the extent to which the COVID-19 pandemic impacts its operations will depend on future developments that are highly uncertain, the Corporation cannot estimate the impact on its business, financial condition or near or long-term financial or operational results with reasonable certainty. Accordingly, the Corporation is disclosing potentially material items of which it is aware. Asset valuation : Currently, the Corporation does not expect the COVID-19 pandemic to affect its ability to account timely for the assets on its balance sheet; however, this could change in future periods due to any number of potential impacts from the COVID-19 pandemic. The COVID-19 pandemic could cause a further and sustained decline in the Corporation's stock price or the occurrence of what management would deem to be a triggering event that could, under certain circumstances, cause us to perform a goodwill impairment test, resulting in an impairment charge being recorded for that period. In the event that the Corporation concludes that all or a portion of its goodwill is impaired, a non-cash charge for the amount of such impairment would be recorded to earnings. Such a charge would have no impact on tangible capital or regulatory capital. Credit : The Corporation is working with customers directly affected by the COVID-19 pandemic. The Corporation has offered assistance in accordance with regulator guidelines. As a result of the current economic slowdown related to the COVID-19 pandemic, the Corporation is engaging in more frequent communication with borrowers to better understand their situation and the challenges faced, allowing it to respond proactively as needs and issues arise. Determining the appropriateness of the allowance for credit losses on loans is complex and requires judgment by management about the effect of matters that are inherently uncertain. Subsequent evaluations of the then-existing loan portfolio, in light of the factors then prevailing, may result in significant changes in the allowance for credit losses on loans in those future periods. Should economic conditions worsen, the Corporation could experience further increases in its required allowance for credit losses and record additional provision expense. It is possible that the Corporation's asset quality measures could worsen at future measurement periods if the effects of the COVID-19 pandemic are prolonged. Operating Segments While the chief decision-makers monitor the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Corporation-wide basis, and operating segments are aggregated into one as operating results for all segments are similar. Accordingly, all of the financial service operations are considered by management to be aggregated in one reportable operating segment. Cash and Cash Equivalents For purposes of the consolidated statement of cash flows, the Corporation defines cash and cash equivalents as cash and due from banks, interest bearing deposits with other banks, and Federal funds sold. Net cash flows are reported for customer loan and deposit transactions, interest bearing time deposits with other banks and borrowings with original maturities of 90 days or less. Restrictions on Cash Note 20, "Interest Rate Swaps," to the consolidated financial statements discloses the cash collateral balances required to be maintained in connection with the Corporation’s interest rate swaps. Debt Securities When purchased, debt securities are classified as held to maturity, trading or available for sale. Debt securities are classified as held to maturity when the Corporation has the positive intent and ability to hold the securities to maturity. Held to maturity securities are carried at amortized cost. Debt securities are classified as trading when purchased principally for the purpose of selling them in the near term, or when the fair value option has been elected. Trading securities are recorded at fair value with changes in fair value included in earnings in non-interest income. Available for sale securities ("AFS") are those securities not classified as held to maturity or trading and are carried at their fair value. Unrealized gains and losses, net of deferred tax, on securities classified as available for sale are recorded as other comprehensive income. Management has not classified any debt securities as held to maturity. Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are generally amortized on the level-yield method without anticipating prepayments, except for mortgage-backed securities where prepayments are anticipated. Premiums on callable debt securities are amortized to their earliest call date. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific-identification method. The Corporation has made a policy election to exclude accrued interest from the amortized cost basis of debt securities and report accrued interest separately in accrued interest receivable and other assets in the consolidated balance sheets. A debt security is placed on nonaccrual status at the time any principal or interest payments become more than 90 days delinquent or if full collection of interest or principal becomes uncertain. Accrued interest for a security placed on nonaccrual is reversed against interest income. There was no accrued interest related to debt securities reversed against interest income for the year ended December 31, 2020. Allowance for Credit Losses (Debt Securities Available-for Sale) For available-for-sale debt securities in an unrealized loss position, the Corporation first assesses whether it intends to sell, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security's amortized cost basis is written down to fair value through income. For debt securities available-for-sale that do not meet the aforementioned criteria, the Corporation evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the allowance when management confirms that an available-for-sale security is uncollectable or when either of the criteria regarding intent or requirement to sell is met. As of December 31, 2020, the Corporation determined that the unrealized loss positions in available-for-sale debt securities were not the result of credit losses, and therefore, an allowance for credit losses was not recorded. See Note 3, "Debt Securities," and Note 6, "Fair Value Measurements," for more information about available-for-sale debt securities. Accrued interest receivable on available-for-sale debt securities totaled $2.2 million at December 31, 2020 and is excluded from the estimate of credit losses. Loans Held for Sale 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 rights retained. The carrying value of the mortgage loan sold is reduced by the amount allocated to the servicing right. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold. Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost. Amortized cost is the principal balance outstanding, net of purchase premiums and discounts, deferred loan fees and costs. Accrued interest receivable totaled $15.4 million at December 31, 2020 and was reported in Accrued interest receivable and other assets on the consolidated balance sheets and is excluded from the estimate of credit losses. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income using the level-yield method without anticipating prepayments. Interest income on mortgage and commercial loans is discontinued and placed on nonaccrual status at the time the loan is 90 days delinquent unless the loan is well secured and in process of collection. Consumer loans continue to accrue interest until they are recorded as charge-offs no later than 180 days past due unless the loan is in the process of collection. Past-due status is based on the contractual terms of the loan. Loans, including loans modified in a troubled debt restructuring, are placed on nonaccrual or recorded as charge-offs at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not received on loans placed on nonaccrual is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Under the cost-recovery method, interest income is not recognized until the loan balance is reduced to zero. Under the cash-basis method, interest income is recorded when the payment is received in cash. For all portfolio segments, loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Purchased Credit Deteriorated ("PCD") Loans The Corporation has purchased loans, some of which have experienced more than insignificant credit deterioration since origination. PCD loans are recorded at the amount paid. An allowance for credit losses is determined using the same methodology as other loans held for investment. The initial allowance for credit losses determined on a collective basis is allocated to individual loans. The sum of the loan's purchase price and allowance for credit losses becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent changes to the allowance for credit losses are recorded through provision expense. Troubled Debt Restructurings ("TDRs") Loans are classified as TDRs when a borrower is experiencing financial difficulty and the Corporation has granted a concession that would not have otherwise been made for a borrower with similar credit characteristics. Prior to granting a modification, the borrower's ability to repay the loan is evaluated, including: current income levels and debt to income ratio, credit score, payment history and an evaluation of secondary repayment sources, if any is updated. The Corporation's policy is to modify loans typically through a payment reduction or through an interest rate reduction for a specified period of time, usually six to twelve months. Interest-only payments may also be approved during the modification period. Principal forgiveness is generally not an option for modification. The allowance for credit loss on a TDR is measured using the same method as all other loans held for investment, except the original interest rate is used to discount the expected cash flows, not the rate specified within the restructuring. When there is a reasonable expectation, at the reporting date, that a TDR will be executed with a borrower the estimated life of the TDR reflects the extension or renewal. Before granting approval to modify a loan in a TDR, the borrower’s ability to repay is evaluated, including: current income levels and debt to income ratio, borrower’s credit score, payment history of the loan and updated evaluation of the secondary repayment source. The Corporation also modifies some loans that are not classified as TDRs as the modification is due to a restructuring where the effective interest rate on the debt is reduced to reflect a decrease in market interest rates. The Corporation's allowance for credit losses reflects the effects of a TDR when management reasonably expects at the reporting date that a TDR will be executed with an individual borrower. The Corporation has implemented various consumer and commercial loan modification programs to provide its borrowers relief from the economic impacts of COVID-19. In accordance with the CARES Act, loans to borrowers experiencing financial difficulty related to the COVID-19 pandemic which were granted short-term modifications after March 1, 2020 and which were not more than 30 days past due as of December 31, 2019 are exempt from TDR classification. In addition, for loans modified in response to the COVID-19 pandemic that do not meet the above delinquency criteria (e.g., more than 30 days past due as of December 31, 2019), the Corporation applies the guidance included in an interagency statement issued by the bank regulatory agencies. This guidance states that loan modifications performed in light of the COVID-19 pandemic, including loan payment deferrals that are up to six months in duration, that were granted to borrowers who were less than 30 days past due as of the implementation date of a loan modification program are exempt from TDR classification. For loan modifications that include a payment deferral and are not TDRs, the borrower’s past due and nonaccrual status will not be impacted during the deferral period. Interest income will continue to be recognized over the contractual life of the loan. Concentration of Credit Risk Most of the Corporation’s business activity is with customers located within the Commonwealth of Pennsylvania and the states of Ohio and New York. Therefore, the Corporation’s exposure to credit risk is significantly affected by changes in the economies of Pennsylvania, Ohio, and New York. Allowance for Credit Losses - Loans The allowance for credit losses on loans represents management’s estimate of expected credit losses over the estimated life of our existing portfolio of loans. The allowance for credit losses is a valuation account that is deducted from the loan's amortized cost basis to present the net amount expected to be collected on the loans. The expense for credit loss recorded through earnings is the amount necessary to maintain the allowance for credit losses on loans at the amount of expected credit losses inherent within the loan portfolio. Loans are recorded as charge-offs against the allowance when management confirms a loan balance is uncollectable. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Management estimates the allowance balance using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts, and other significant qualitative and quantitative factors. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, changes in environmental conditions, delinquency level, segment growth rates and changes in duration within new markets, or other relevant factors. For further information on the ACL on loans, see Note 4, "Loans," for additional detail. The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist. The Corporation has segregated its portfolio segments based on federal call report codes which classify loans based on the primary collateral supporting the loan. The following are the Corporation's segmented portfolios: 1-4 Family Construction : The Bank originates construction loans to finance 1-4 family residential buildings. Construction loans include not only construction of new structures, but also additions or alterations to existing structures and the demolition of existing structures to make way for new structures. Construction loans are generally secured by real estate. The primary risk characteristics are specific to the uncertainty on whether the construction will be completed according to the specifications and schedules. Factors that may influence the completion of construction may be customer specific, or related to changes in general economic conditions. Other construction loans and all land development and other land loans : The Bank originates construction loans to finance land development preparatory to erecting new structures or the on-site construction of industrial, commercial, or multi-family buildings. Construction loans include not only construction of new structures, but also additions or alterations to existing structures and the demolition of existing structures to make way for new structures. Construction loans are generally secured by real estate. The primary risk characteristics are specific to the uncertainty on whether the construction will be completed according to the specifications and schedules. Factors that may influence the completion of construction may be customer specific, such as the quality and depth of property management, or related to changes in general economic conditions. Farmland (including farm residential and other improvements) : The Bank originates loans secured by farmland and improvements thereon, secured by mortgages. Farmland includes all land known to be used or usable for agricultural purposes, such as crop and livestock production. Farmland also includes grazing or pasture land, whether tillable or not and whether wooded or not. The primary risk characteristics are specific to the uncertainty on production, market, financial, environmental and human resources. Home equity lines of credit : The primary risk characteristics associated with home equity lines of credit typically involve changes to the borrower, including unemployment or other loss of income; unexpected significant expenses, such as major medical expenses, catastrophic events, divorce and death. Home equity lines of credit are typically originated with variable or floating interest rates, which could expose the borrower to higher payments in a rising interest rate environment. Real estate values could decrease and cause the value of the underlying property to fall below the loan amount, creating additional potential loss exposure for the Bank. Residential Mortgages secured by first liens : The Bank originates one-to-four family residential mortgage loans primarily within central and northwest Pennsylvania, central and northeast Ohio and western New York. These loans are secured by first liens on a primary residence or investment property. The primary risk characteristics associated with residential mortgage loans typically involve major changes to the borrower, including unemployment or other loss of income; unexpected significant expenses, such as major medical expenses, catastrophic events, divorce or death. Residential mortgage loans that have adjustable rates could expose the borrower to higher payments in a rising interest rate environment. Real estate values could decrease and cause the value of the underlying property to fall below the loan amount, creating additional potential loss exposure for the Bank. Residential Mortgages secured by junior liens : The Bank originates loans secured by junior liens against one to four family properties primarily within central and northwest Pennsylvania, central and northeast Ohio and western New York. Loans secured by junior liens are primarily in the form of an amortizing home equity loan. These loans are subordinate to a first mortgage which may be from another lending institution. The primary risk characteristics associated with loans secured by junior liens typically involve major changes to the borrower, including unemployment or other loss of income, unexpected significant expenses, such as for major medical expenses, catastrophic events, divorce or death. Real estate values could decrease and cause the value of the property to fall below the loan amount, creating additional potential loss exposure for the Bank. Multifamily (5 or more) residential properties : The Bank originates mortgage loans for multifamily properties primarily within central and northwest Pennsylvania, central and northeast Ohio and western New York. Multifamily loans are expected to be repaid from the cash flows of the underlying property so the collective amount of rents must be sufficient to cover all operating expenses, property management and maintenance, taxes and debt service. Increases in vacancy rates, interest rates or other changes in general economic conditions can have an impact on the borrower and its ability to repay the loan. Owner-occupied, nonfarm nonresidential properties : The Bank originates mortgage loans to operating companies primarily within central and northwest Pennsylvania, central and northeast Ohio and western New York. Owner-occupied real estate properties primarily include retail buildings, medical buildings and industrial/warehouse space. Owner-occupied loans are typically repaid first by the cash flows generated by the borrower’s business operations. The primary risk characteristics are specific to the underlying business and its ability to generate sustainable profitability and positive cash flow. Factors that may influence a borrower's ability to repay their loan include demand for the business’ products or services, the quality and depth of management, the degree of competition, regulatory changes, and general economic conditions. Non-owner occupied, nonfarm nonresidential properties : The Bank originates mortgage loans for commercial real estate that is managed as an investment property primarily within central and northwest Pennsylvania, central and northeast Ohio and western New York. Commercial real estate properties primarily include retail buildings/shopping centers, hotels, office/medical buildings and industrial/warehouse space. Increases in vacancy rates, interest rates or other changes in general economic conditions can have an impact on the borrower and its ability to repay the loan. Commercial real estate loans are generally considered to have a higher degree of credit risk as they may be dependent on the ongoing success and operating viability of a fewer number of tenants who are occupying the property and who may have a greater degree of exposure to economic conditions. Agricultural production and other loans to farmers : The Bank originates loans secured or unsecured to farm owners and operators (including tenants) or to nonfarmers for the purpose of financing agricultural production, including the growing and storing of crops, the marketing or carrying of agricultural products by the growers thereof, and the breeding, raising, fattening, or marketing of livestock, and for purchases of farm machinery, equipment, and implements. The primary risk characteristics are specific to the uncertainty on production, market, financial, environmental and human resources. Commercial and Industrial : The Bank originates lines of credit and term loans to operating companies for business purposes. The loans are generally secured by business assets such as accounts receivable, inventory, business vehicles and equipment as well as the stock of a company, if privately held. Commercial and Industrial loans are typically repaid first by the cash flows generated by the borrower’s business operations. The primary risk characteristics are specific to the underlying business and its ability to generate sustainable profitability and positive cash flow. Factors that may influence a borrower's ability to repay their loan include demand for the business’ products or services, the quality and depth of management, the degree of competition, regulatory changes, and general economic conditions. The ability of the Bank to foreclose and realize sufficient value from business assets securing these loans is often uncertain. To mitigate the risk characteristics of commercial and industrial loans, commercial real estate may be included as a secondary source of collateral. The Bank will often require more frequent reporting requirements from the borrower in order to better monitor its business performance. Credit cards : The Bank originates credit cards offered to individuals and businesses for household, family, other personal and business expenditures. Credit cards generally are floating rate loans and include both unsecured and secured lines. Credit card loans generally do not have stated maturities and are unconditionally cancellable. The primary risk characteristics associated with credit cards typically involve major changes to the borrower, including unemployment or other loss of income, unexpected significant expenses, such as for major medical expenses, catastrophic events, divorce or death. Other revolving credit plans : The Bank originates lines of credit to individuals for household, family, and other personal expenditures. Consumer loans generally have higher interest rates and shorter terms than residential loans but tend to have higher credit risk due to the type of collateral securing the loan or in some cases the absence of collateral. The primary risk characteristics associated with other revolving loans typically involve major changes to the borrower, including unemployment or other loss of income, unexpected significant expenses, such as for major medical expenses, catastrophic events, divorce or death. Automobile : The Bank originates consumer loans extended for the purpose of purchasing new and used passenger cars and other vehicles such as minivans, vans, sport-utility vehicles, pickup trucks, and similar light trucks for personal use. The primary risk characteristics associated with automobile loans typically involve major changes to the borrower, including unemployment or other loss of income, unexpected significant expenses, such as for major medical expenses, catastrophic events, divorce or death. Other consumer : The Bank originates loans to individuals for household, family, and other personal expenditures. This also represents all other loans that cannot be categorized in any of the previous mentioned consumer loan segments. Consumer loans generally have higher interest rates and shorter terms than residential loans but tend to have higher credit risk due to the type of collateral securing the loan or in some cases the absence of collateral. The primary risk characteristics associated with automobile loans typically involve major changes to the borrower, including unemployment or other loss of income, unexpected significant expenses, such as for major medical expenses, catastrophic events, divorce or death. Obligations (other than securities and leases) of states and political subdivisions : The Bank originates various types of loans made directly to municipalities. These loans are repaid through general cash flows or through specific revenue streams, such as water and sewer fees. The primary risk characteristics associated with municipal loans are the municipalities ability to manage cash flow, balance the fiscal budget, fixed asset and infrastructure requirements. Additional risks include changes in demographics, as well as social and political conditions. Other loans : The Bank originates other loans, such as loans to nonprofit organizations, including churches, hospitals, educational and charitable institutions, clubs, and similar associations. The primary risk characteristics associated with these types of loans are repayment, demographic, social, political and reputation risks. Overdrafts : The Bank reports overdrawn customer deposit balances as loans. Methods utilized by management to estimate expected credit losses include a discounted cash flow ("DCF") model that discounts instrument-level contractual cash flows, adjusted for prepayments and curtailments, incorporating loss expectations, and a weighted average remaining maturity ("WARM") model which contemplates expected losses at a pool-level, utilizing historic loss information. Under both models, management estimates the allowance for credit losses on loans using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. After the end of the reasonable and supportable forecast period, the loss rates revert to the mean loss rate over a period of eight quarters. Historical credit loss experience, including examinati

Business Combinations [Abstract]
Business Combinations	Business Combinations On July 17, 2020, the Corporation completed its previously announced acquisition of Bank of Akron, pursuant to the Merger Agreement. Under the terms of the Merger Agreement, Bank of Akron merged with and into CNB Bank (the "Merger"), with CNB Bank continuing as the surviving entity. Banking offices of Bank of Akron will operate under the trade name BankOnBuffalo, a division of CNB Bank. Pursuant to the Merger Agreement, for each share of Bank of Akron common stock, Bank of Akron shareholders were entitled to elect to receive either (x) $215.00 in cash or (y) 6.6729 shares of the Corporation's common stock and also received cash in lieu of fractional shares. Elections were subject to proration procedures whereby at least 75% of the shares of Bank of Akron common stock were exchanged for shares of the Corporation's common stock. Based on the elections and proration procedures, the total consideration payable to Bank of Akron shareholders was approximately $40.8 million, comprised of approximately $16.1 million in cash and 1,501,321 shares of the Corporation's common stock, net of fractional shares, valued at approximately $24.7 million based on the July 17, 2020 closing price of $16.43 per share of the Corporation's common stock. Bank of Akron's results of operations were included in the Corporation's results of operations beginning July 17, 2020. The Corporation incurred $4.0 million of merger-related expenses during the year ended December 31, 2020, consisting largely of professional services of attorneys, accountants, investment bankers and other advisors. There were $170 thousand in merger-related expenses incurred during the year ended December 31, 2019. July 17, 2020 Merger consideration Value of stock consideration assigned to Bank of Akron common shares exchanged for stock paid to shareholders $ 24,667 Value of cash consideration for Bank of Akron common stock exchanged for cash 16,126 Total merger consideration $ 40,793 Core deposit intangible ("CDI") of $613 thousand and goodwill of $5.0 million were recognized as a result of the acquisition. Goodwill represents the future economic benefits arising from net assets acquired that are not individually identified and separately recognized and is attributable to synergies expected to be derived from the combination of the two entities. Goodwill recognized in this transaction is not deductible for income tax purposes. July 17, 2020 Identifiable net assets acquired, at fair value Assets acquired Cash and due from banks $ 78,830 Interest bearing deposits with other banks 10,148 Investment securities 29,407 Loans, net of allowance for credit losses on PCD loans 319,063 Premises and equipment, net 4,265 Core deposit intangible 613 Deferred tax assets 2,777 Bank owned life insurance 8,187 Accrued interest receivable and other assets 5,307 Total assets acquired $ 458,597 Liabilities assumed Deposits $ 419,475 Accrued interest payable and other liabilities 3,348 Total liabilities assumed 422,823 Total fair value of identifiable net assets 35,774 Total merger consideration 40,793 Goodwill recognized $ 5,019 The Corporation accounted for this transaction under the acquisition method of accounting in accordance with ASC 805, Business Combinations, which requires purchased assets and liabilities assumed and consideration exchanged to be recorded at their respective estimated fair values at the date of acquisition. The determination of estimated fair values required management to make certain estimates about discount rates, future expected cash flows, market conditions at the time of the acquisition and other future events that are highly subjective in nature and subject to refinement for up to one year after the closing date of acquisition as additional information relative to the closing date fair values becomes available and such information is considered final, whichever is earlier. The calculation of goodwill is subject to change for up to one year after closing date of the transaction as additional information relative to closing date estimates and uncertainties becomes available. Financial assets acquired in a business combination after January 1, 2020 are recorded in accordance with ASC Topic 326, after which acquired assets are separated into two types. Purchased credit deteriorated ("PCD") assets are acquired assets that, as of the acquisition date, have experienced a more-than-insignificant deterioration in credit quality since origination. Non-PCD assets are acquired assets that have experienced no or insignificant deterioration in credit quality since origination. To distinguish between the two types of acquired assets, the Corporation evaluates risk characteristics that have been determined to be indicators of deteriorated credit quality. In the case of loans, the determining criteria may involve general characteristics, such as loan payment history or changes in creditworthiness since the loan was originated, while others are relevant to recent economic conditions, such as borrowers in industries impacted by the COVID-19 pandemic. Securities The estimated fair values of the securities were calculated utilizing Level 2 inputs. The securities acquired are bought and sold in active markets. Prices for these instruments were obtained through security industry sources that actively participate in the buying and selling of securities. Loans Bank of Akron’s loan portfolio was recorded at fair value at the date of acquisition. A valuation of Bank of Akron’s loan portfolio was performed as of the acquisition date in accordance with ASC 820 to assess the fair value of the loan portfolio, considering adjustments for market discount rates, credit, and liquidity. The loan portfolio was segmented into two groups: non-PCD loans and PCD loans. The non-PCD loans were pooled based on similar characteristics, such as loan type, fixed or adjustable interest rates, payment type, index rate and caps/floors, and non-accrual status. The PCD loans were valued on a pooled basis and at the loan level with similar characteristics noted above. Premises and Equipment Fair values are based upon appraisal values. In addition to owned properties, Bank of Akron operated one property subject to a lease agreement. Core deposit intangible The CDI on non-maturing deposits was determined by evaluating the underlying characteristics of the deposit relationships, including customer attrition, deposit interest rates and maintenance costs, fee income and costs of alternative funding using the discounted cash flow approach. The core deposit intangibles represent the costs saved by the Corporation between maintaining the existing deposits and obtaining alternative funds over the life of the deposit base. Fixed maturity deposits In determining the fair value of certificates of deposit, the cash flows of the contractual interest payments during the specific period of the certificates of deposit and scheduled principal payout were discounted to present value at market-based interest rates. Supplemental Pro Forma Financial Information The following table presents certain unaudited pro forma financial information for illustrative purposes only, for the year ended December 31, 2020 and 2019, respectively, as if Bank of Akron had been acquired on January 1, 2019. This unaudited pro forma information combines the historical results of Bank of Akron with the Corporation’s consolidated historical results and includes certain adjustments reflecting the estimated impact of certain fair value adjustments for the respective periods. The pro forma information is not indicative of what would have occurred had the acquisition occurred as of the beginning of the year prior to the acquisition. The unaudited pro forma information does not consider any changes to the provision expense resulting from recording loan assets at fair value, cost savings or business synergies. As a result, actual amounts would have differed from the unaudited pro forma information presented and the differences could be significant.

Securities with unrealized losses at December 31, 2020 and December 31, 2019, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, are as follows: December 31, 2020 Less than 12 Months 12 Months or More Total Description of Securities Fair Unrealized Fair Unrealized Fair Unrealized U.S. Gov’t sponsored entities $ 24,991 $ (60) 0 0 $ 24,991 $ (60) State & political subdivisions 3,854 (19) 164 (103) 4,018 (122) Residential & multi-family mortgage 44,092 (119) 3,277 (19) 47,369 (138) Corporate notes & bonds 0 0 4,545 (400) 4,545 (400) Pooled SBA 525 (1) 0 0 525 (1) Other 0 0 979 (41) 979 (41) $ 73,462 $ (199) $ 8,965 $ (563) $ 82,427 $ (762) December 31, 2019 Less than 12 Months 12 Months or More Total Description of Securities Fair Unrealized Fair Unrealized Fair Unrealized U.S. Gov’t sponsored entities 7,040 (3) 14,989 (16) 22,029 (19) State & political subdivisions 826 (5) 684 (97) 1,510 (102) Residential and multi-family mortgage 41,841 (346) 32,555 (539) 74,396 (885) Corporate notes & bonds 0 0 4,718 (282) 4,718 (282) Pooled SBA 8,560 (80) 6,075 (83) 14,635 (163) Other 0 0 964 (56) 964 (56) 58,267 (434) 59,985 (1,073) 118,252 (1,507) The Corporation evaluates securities for other-than-temporary impairment on a quarterly basis, or more frequently when economic or market conditions warrant such an evaluation. At December 31, 2020 and 2019, management performed an assessment for possible other-than-temporary impairment of the Corporation’s debt securities, relying on information obtained from various sources, including publicly available financial data, ratings by external agencies, brokers and other sources. Based on the results of the assessment, management believes impairment of these debt securities at December 31, 2020 and 2019 to be temporary. For the securities that comprise corporate notes and bonds and the securities that are issued by state and political subdivisions, management monitors publicly available financial information, such as filings with the Securities and Exchange Commission, in order to evaluate the securities for other-than-temporary impairment. For financial institution issuers, management monitors information from quarterly "call" report filings that are used to generate Uniform Bank Performance Reports. All other securities that were in an unrealized loss position at the balance sheet date were reviewed by management, and issuer-specific documents were reviewed as appropriate given the following considerations; the financial condition and near-term prospects of the issuer and whether downgrades by bond rating agencies have occurred, and whether management does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery. As of December 31, 2020 and 2019, management concluded that the securities described in the previous paragraph were not other-than-temporarily impaired for the following reasons: • There is no indication of any significant deterioration of the creditworthiness of the institutions that issued the securities. • All contractual interest payments on the securities have been received as scheduled, and no information has come to management’s attention through the processes previously described which would lead to a conclusion that future contractual payments will not be timely received. The Corporation does not intend to sell and it is not more likely than not that it will be required to sell the securities in an unrealized loss position before recovery of its amortized cost basis. Trading securities at December 31, 2020 and December 31, 2019 are as follows: December 31, 2020 December 31, 2019 Corporate equity securities $ 4,343 $ 7,946 Mutual funds 1,283 807 Money market 404 350 Corporate notes and bonds 569 655 U.S. Government sponsored entities 50 51 Total $ 6,649 $ 9,809 During December 31, 2020, December 31, 2019, and December 31, 2018, the Corporation sold trading securities. Proceeds were $5,935 in December 31, 2020, $301 in December 31, 2019 and $455 in December 31, 2018, resulting in net realized gains of $75 in December 31, 2020, $16 in December 31, 2019, and $151 in December 31, 2018. During 2019, the Corporation sold Visa Class B shares. The proceeds and realized gain related to the sale of the Visa Class B shares were $463.

The Bank attempts to limit concentrations within specific industries by utilizing dollar limitations to single industries or customers, and by entering into participation agreements with third parties. Collateral requirements are established based on management’s assessment of the customer. The Corporation maintains lending policies to control the quality of the loan portfolio. These policies delegate the authority to extend loans under specific guidelines and underwriting standards. These policies are prepared by the Corporation’s management and reviewed and ratified annually by the Corporation’s Board of Directors. As a result of the adoption of ASC 326 effective January 1, 2020, there is a lack of comparability in both the allowance and provisions for credit losses for the periods presented. Results for reporting periods beginning after January 1, 2020 (as reflected in the table below) are presented using the CECL methodology, while comparative period information continues to be reported in accordance with the incurred loss methodology in effect for prior fiscal years. See Note 1, "Summary of Significant Accounting Policies," for details regarding the adoption of ASC 326. At December 31, 2020, the Corporation incorporated the loans acquired through Bank of Akron and evaluated its qualitative factors as a result of the COVID-19 pandemic. As a result, at December 31, 2020, the Corporation added a qualitative factor related to the unfavorable economic environment driven by the COVID-19 pandemic. Management evaluates the factor based upon internal and external expectations of economic activity. Management also included a qualitative factor related to loans with payment deferrals specifically related to the COVID-19 pandemic. Transactions in the allowance for credit losses for the year ended December 31, 2020 were as follows: Beginning Impact of ASC 326 Adoption Initial Allowance on Loans Purchased with Credit Deterioration (Charge-offs) Recoveries Provision (Benefit) for Credit Loss Expense Ending Allowance (After ASC 326 Adoption) Farmland $ 190 $ 61 $ 0 $ 0 $ 0 $ (30) $ 221 Owner-occupied, nonfarm nonresidential properties 2,390 (754) 82 (61) 12 2,031 3,700 Agricultural production and other loans to farmers 25 5 0 0 0 (6) 24 Commercial and Industrial 4,105 (631) 216 (2,779) 39 5,283 6,233 Obligations (other than securities and leases) of states and political subdivisions 1,022 (231) 0 0 0 207 998 Other loans 41 8 0 0 0 19 68 Other construction loans and all land development and other land loans 2,327 780 228 0 125 (1,504) 1,956 Multifamily (5 or more) residential properties 1,087 312 24 0 0 1,301 2,724 Non-owner occupied, nonfarm nonresidential properties 3,980 2,547 335 (1,522) 52 3,266 8,658 1-4 Family Construction 56 (35) 0 0 0 61 82 Home equity lines of credit 180 421 22 (6) 1 367 985 Residential Mortgages secured by first liens 1,220 1,100 73 (285) 65 2,366 4,539 Residential Mortgages secured by junior liens 114 135 0 (158) 2 148 241 Other revolving credit plans 296 378 0 (137) 21 (51) 507 Automobile 156 (96) 0 (29) 2 99 132 Other consumer 1,960 1,021 0 (1,513) 130 1,364 2,962 Credit cards 84 (58) 0 (153) 14 179 66 Overdrafts 240 0 0 (435) 185 254 244 Total loans $ 19,473 $ 4,963 $ 980 $ (7,078) $ 648 $ 15,354 $ 34,340 Transactions in the allowance for loan losses for the year ended December 31, 2019 were as follows: Commercial, Commercial Residential Consumer Credit Overdrafts Total Allowance for loan losses, January 1, 2019 $ 7,341 $ 7,490 $ 2,156 $ 2,377 $ 103 $ 237 $ 19,704 Charge-offs (205) (3,391) (386) (2,200) (116) (453) (6,751) Recoveries 17 124 73 154 15 113 496 Provision for loan losses 1,134 2,729 (344) 2,080 82 343 6,024 Allowance for loan losses, December 31, 2019 $ 8,287 $ 6,952 $ 1,499 $ 2,411 $ 84 $ 240 $ 19,473 Transactions in the allowance for loan losses for the year ended December 31, 2018 were as follows: Commercial, Commercial Residential Consumer Credit Overdrafts Total Allowance for loan losses, January 1, 2018 $ 6,160 $ 9,007 $ 2,033 $ 2,179 $ 120 $ 194 $ 19,693 Charge-offs (253) (3,337) (315) (2,279) (90) (319) (6,593) Recoveries 171 30 67 141 33 90 532 Provision for loan losses 1,263 1,790 371 2,336 40 272 6,072 Allowance for loan losses, December 31, 2018 $ 7,341 $ 7,490 $ 2,156 $ 2,377 $ 103 $ 237 $ 19,704 The following table presents the balance in the allowance for loan losses and the recorded investment in loans by portfolio segment and is based on the Corporation’s impairment method as of December 31, 2019.

This evaluation is performed using the Corporation’s internal underwriting policies. The Corporation has no further loan commitments to customers whose loans are classified as a troubled debt restructuring. During the years ended December 31, 2020 and December 31, 2019, the terms of certain loans were modified as troubled debt restructurings. The modification of the terms of such loans included either or both of the following: a reduction of the stated interest rate of the loan; or an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk. The Corporation had an amortized cost in troubled debt restructurings of $15,088 and $10,951 as of December 31, 2020 and 2019, respectively. The following table presents loans by class modified as troubled debt restructurings that occurred during the years ended December 31, 2020, December 31, 2019, and December 31, 2018: Year Ended December 31, 2020 Number of Pre-Modification Post-Modification Owner-occupied, nonfarm nonresidential properties 1 $ 260 $ 260 Commercial and Industrial 6 1,140 1,140 Other construction loans and all land development and other land loans 1 46 46 Non-owner occupied, nonfarm nonresidential properties 1 3,684 3,684 Residential Mortgages secured by first liens 2 309 309 Total loans 11 $ 5,439 $ 5,439 Year Ended December 31, 2019 Number of Pre-Modification Post-Modification Commercial, industrial, and agricultural 0 $ 0 $ 0 Commercial mortgages 1 383 383 Residential real estate 0 0 0 Consumer 0 0 0 Credit cards 0 0 0 Total 1 $ 383 $ 383 Year Ended December 31, 2018 Number of Pre-Modification Post-Modification Commercial, industrial, and agricultural 0 $ 0 $ 0 Commercial mortgages 5 1,570 1,570 Residential real estate 0 0 0 Consumer 0 0 0 Credit cards 0 0 0 Total 5 $ 1,570 $ 1,570 The troubled debt restructurings described above increased the allowance for credit losses by $0, $0 and $351 during the years ended December 31, 2020, December 31, 2019, and December 31, 2018, respectively. A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms. All loans modified in troubled debt restructurings are performing in accordance with their modified terms as of December 31, 2020 and December 31, 2019 and no principal balances were forgiven in connection with the loan restructurings. Generally, nonperforming troubled debt restructurings are restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time (generally six months) and the ultimate collectability of the total contractual principal and interest is no longer in doubt. Credit Quality Indicators The Corporation categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Corporation analyzes loans individually to classify the loans as to credit risk. The Corporation uses the following definitions for risk ratings: Special Mention: Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the Corporation’s credit position at some future date. Substandard: Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Corporation will sustain some loss if the deficiencies are not corrected. Doubtful: Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

Fair Value

Fair Value Disclosures [Abstract]
Fair Value	Fair Value Fair Value Measurement Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The following three levels of inputs are used to measure fair value: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. The Corporation used the following methods and significant assumptions to estimate fair value: Investment Securities : The fair values of most trading securities and debt securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1) or matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather relying on the securities’ relationship to other benchmark quoted securities (Level 2). These models utilize the market approach with standard inputs that include, but are not limited to benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data. For certain securities that observable inputs about the specific issuer are not available, fair values are estimated using observable data from other securities presumed to be similar or other market data on other similar securities (Level 3). Derivatives : The Corporation’s derivative instruments are interest rate swaps that are similar to those that trade in liquid markets. As such, significant fair value inputs can generally be verified and do not typically involve significant management judgments (Level 2). Individually Evaluated Loans : The fair value of individually evaluated loans with specific allocations of the allowance for credit losses is generally based on recent real estate appraisals prepared by third-parties. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Management also adjusts appraised values based on the length of time that has passed since the appraisal date and other factors. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. Non-real estate collateral may be valued using an appraisal, net book value per the borrower's financial statements, or aging reports, adjusted or discounted based on management's historical knowledge, changes in market conditions from the time of the valuation, and management's expertise and knowledge of the client and client's business, resulting in a Level 3 fair value classification. Individually evaluated loans are evaluated on a quarterly basis for additional impairment and adjusted in accordance with the allowance policy. Assets and liabilities measured at fair value on a recurring basis are as follows at December 31, 2020 and December 31, 2019: Fair Value Measurements at December 31, 2020 Using Description Total Quoted Prices in Significant Other Significant Assets: Securities Available For Sale: U.S. Government sponsored entities $ 157,042 $ 0 $ 157,042 $ 0 States and political subdivisions 70,883 0 70,819 64 Residential and multi-family mortgage 315,192 15,039 300,153 0 Corporate notes and bonds 14,926 0 14,926 0 Pooled SBA 25,886 0 25,886 0 Other 979 979 0 0 Total Securities Available For Sale $ 584,908 $ 16,018 $ 568,826 $ 64 Interest rate swaps $ 4,017 $ 0 $ 4,017 $ 0 Trading Securities: Corporate equity securities $ 4,343 $ 4,343 $ 0 $ 0 Mutual funds 1,283 1,283 0 0 Certificates of deposit 404 404 0 0 Corporate notes and bonds 569 569 0 0 U.S. Government sponsored entities 50 0 50 0 Total Trading Securities $ 6,649 $ 6,599 $ 50 $ 0 Liabilities Interest rate swaps $ (4,785) $ 0 $ (4,785) $ 0 Fair Value Measurements at December 31, 2019 Using Description Total Quoted Prices in Significant Other Significant Assets: Securities Available For Sale: U.S. Government sponsored entities $ 127,094 $ 0 $ 127,094 $ 0 States and political subdivisions 104,363 0 104,363 0 Residential and multi-family mortgage 276,636 0 273,841 2,795 Corporate notes and bonds 8,082 0 8,082 0 Pooled SBA 25,174 0 25,174 0 Other 964 964 0 0 Total Securities Available For Sale $ 542,313 $ 964 $ 538,554 $ 2,795 Interest rate swaps $ 1,877 $ 0 $ 1,877 $ 0 Trading Securities: Corporate equity securities $ 7,946 $ 7,946 $ 0 $ 0 Mutual funds 807 807 0 0 Certificates of deposit 350 350 0 0 Corporate notes and bonds 655 655 0 0 U.S. Government sponsored entities 51 0 51 0 Total Trading Securities $ 9,809 $ 9,758 $ 51 $ 0 Liabilities Interest rate swaps $ (2,362) $ 0 $ (2,362) $ 0 The table below presents a reconciliation of the fair value of securities available for sale measured on a recurring basis using significant unobservable inputs (Level 3) for the year ended December 31, 2020 and 2019, respectively: States and Political Subdivisions Residential & Multi-Family Mortgage Balance, January 1, 2020 $ 0 $ 2,795 Purchases 422 0 Total gains or (losses): Included in other comprehensive income (loss) 0 0 Transfers out of Level 3 (358) $ (2,795) Balance, December 31, 2020 $ 64 $ 0 Residential & Multi-Family Mortgage Balance, January 1, 2019 $ 0 Purchases 2,796 Total gains or (losses): Included in other comprehensive income (loss) (1) Balance, December 31, 2019 $ 2,795 Assets and liabilities measured at fair value on a non-recurring basis are as follows at December 31, 2020 and December 31, 2019: Fair Value Measurements at December 31, 2020 Using Description Total Quoted Prices in Significant Other Significant Assets: Collateral-dependent loans: Farmland $ 659 0 0 $ 659 Owner-occupied, nonfarm nonresidential properties 329 0 0 329 Commercial and industrial 3,680 0 0 3,680 Other construction loans and all land development loans and other land loans 1,790 0 0 1,790 Multifamily (5 or more) residential properties 0 0 0 0 Non-owner occupied, nonfarm nonresidential 9,622 0 0 9,622 Residential mortgages secured by first liens 659 0 0 659 Fair Value Measurements at December 31, 2019 Using Description Total Quoted Prices in Significant Other Significant Assets: Impaired loans: Commercial, industrial, and agricultural $ 2,910 0 0 $ 2,910 Commercial mortgages 1,147 0 0 1,147 A loan is considered to be a collateral dependent loan when, based on current information and events, the Corporation expects repayment of the financial assets to be provided substantially through the operation or sale of the collateral and the Corporation has determined that the borrower is experiencing financial difficulty as of the measurement date. The allowance for credit losses is measured by estimating the fair value of the loan based on the present value of expected cash flows, the market price of the loan, or the underlying fair value of the loan’s collateral. For real estate loans, fair value of the loan’s collateral is determined by third-party appraisals, which are then adjusted for the estimated selling and closing costs related to liquidation of the collateral. For this asset class, the actual valuation methods (income, sales comparable, or cost) vary based on the status of the project or property. For example, land is generally based on the sales comparable method while construction is based on the income and/or sales comparable methods. The unobservable inputs may vary depending on the individual assets with no one of the three methods being the predominant approach. The Corporation reviews the third-party appraisal for appropriateness and may adjust the value downward to consider selling and closing costs. For non-real estate loans, fair value of the loan’s collateral may be determined using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business.

The estimated fair values would also not apply to subsequent dates. The fair value of other equity interests is based on the net asset values provided by the underlying investment partnership. ASU 2015-7 removes the requirement to categorize within the fair value hierarchy all investments measured using the net asset value per share practical expedient and related disclosures. In addition, other assets and liabilities that are not financial instruments, such as premises and equipment, are not included in the disclosures.

Leases [Abstract]
Leases	Leases Operating lease assets represent our right to use an underlying asset during the lease term and operating lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease assets and liabilities are recognized at lease commencement based on the present value of the remaining lease payments using a discount rate that represents our incremental borrowing rate at the lease commencement date. Operating lease cost, which is comprised of amortization of the operating lease asset and the implicit interest accreted on the operating lease liability, is recognized on a straight-line basis over the lease term, and is recorded in net occupancy expense in the consolidated statements of income. The Corporation leases certain full-serve branch offices, land and equipment. Leases with an initial term of twelve months or less are not recorded on the balance sheet. Most leases include one or more options to renew and the exercise of the lease renewal options are at the Corporation's sole discretion. The Corporation includes lease extension and termination options in the lease term if, after considering relevant economic factors, it is reasonably certain the Corporation will exercise the option. Certain lease agreements of the Corporation include rental payments adjusted periodically for changes in the consumer price index.

The following table sets forth the change in the benefit obligation of the plan as of and for the years ended December 31, 2020 and December 31, 2019: December 31, 2020 December 31, 2019 Benefit obligation at beginning of year $ 2,030 $ 2,427 Interest cost 51 89 Service cost 61 74 Actual claims (36) (42) Actuarial gain (277) (518) Benefit obligation at end of year $ 1,829 $ 2,030 Amounts recognized in accumulated other comprehensive income at December 31, 2020 and December 31, 2019 consist of: December 31, 2020 December 31, 2019 Net actuarial gain $ 435 $ 158 Tax effect (92) (34) $ 343 $ 124 The accumulated benefit obligation was $1,828 and $2,030 at December 31, 2020 and December 31, 2019, respectively. The following table sets forth the components of net periodic benefit cost and other amounts recognized in other comprehensive income: December 31, 2020 December 31, 2019 December 31, 2018 Service cost $ 61 $ 74 $ 87 Interest cost 51 89 83 Net amortization of transition obligation and actuarial loss 0 23 84 Net periodic benefit cost 112 186 254 Net gain (277) (518) (404) Amortization 0 (23) (84) Total recognized in other comprehensive income (277) (541) (488) Total recognized in net periodic benefit cost and other comprehensive income $ (165) $ (355) $ (234) The estimated net gain that will be amortized from accumulated other comprehensive income into net periodic benefit cost over the next fiscal year is zero. The weighted average discount rate used to calculate net periodic benefit cost was 2.59% for year ended December 31, 2020, 3.78% for year ended December 31, 2019, and 3.13% for year ended December 31, 2018. The weighted average rate used to calculate accrued benefit obligations was 1.55% for year ended December 31, 2020, 2.59% for year ended December 31, 2019, and 3.78% for year ended December 31, 2018. The health care cost trend rate used to measure the expected costs of benefits is 5.0% for 2021 and thereafter. A one percent increase in the health care trend rates would result in an increase of $136 in the benefit obligation as of December 31, 2020, and would increase the service and interest costs by $8 in future periods. A similar one percent decrease in health care trend rates would result in a decrease of $124 and $9 in the benefit obligation and services and interest costs, respectively, at December 31, 2020.

Contingency	ContingencyOn March 28, 2018, the Corporation received a notice of assessment from the Pennsylvania Department of Revenue that reported a sales tax assessment amount of $824 plus interest and penalties of $339 resulting in a total assessed balance of $1,163. The notice of assessment covers the period from January 1, 2013 through July 31, 2016. The Corporation has evaluated the specific items on which sales tax has been assessed in conjunction with its legal counsel and has determined that it is probable that the Corporation has some liability based on a review of the Pennsylvania tax laws that apply to the assessed items. The Corporation previously expensed $96, of which $50 was remitted to the Pennsylvania Department of Revenue during the year ended December 31, 2018. The Corporation expensed an additional $150 in the third quarter of 2019. The remainder of the total assessed balance of $1,163 that had not been expensed relates primarily to sales tax assessments associated with data processing and banking equipment maintenance, which the Corporation’s management and legal counsel have concluded were improperly assessed based on current Pennsylvania sales tax law. In December 2019 the Corporation and the Pennsylvania Board of Finance and Revenue reached a agreement whereby the Corporation agreed to pay a total of $60 tax plus $5 interest to settle the notice of assessment. The Corporation remitted the remaining balance due of $15 prior to December 31, 2019 and reversed previously recognized expense of $181.

Stock-Based Compensation

Stock-Based Compensation	12 Months Ended

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation The Corporation has a stock incentive plan, which is administered by a committee of the Board of Directors and which permits the Corporation to provide various types of stock-based compensation to its key employees, directors, and/or consultants, including time-based and performance-based shares of restricted stock. The Corporation previously maintained the CNB Financial Corporation 2009 Stock Incentive Plan, which terminated in accordance with its terms on February 10, 2019, and currently maintains the CNB Financial Corporation 2019 Omnibus Incentive Plan (the "2019 Stock Incentive Plan"), which was approved by the Corporation’s shareholders and became effective on April 16, 2019. The 2019 Stock Incentive Plan provides for up to 507,671 shares of common stock to be awarded in the form of nonqualified options or restricted stock. For key employees, the vesting of time-based restricted stock is one-third, one-fourth, or one-fifth of the granted restricted shares per year, beginning one year after the grant date, with 100% vesting on the third, fourth or fifth anniversary of the grant date, respectively. Prior to 2018, for non-employee directors, the vesting schedule was one-third of the granted restricted shares per year, beginning one year after the grant date, with 100% vested on the third anniversary of the grant date. Beginning in 2018, stock compensation received by non-employee directors vests immediately. All stock-based compensation grants during the years ending December 31, 2020 , December 31, 2019 and December 31, 2018 and outstanding at December 31, 2020 , December 31, 2019 and December 31, 2018 were restricted stock. During December 31, 2020, December 31, 2019, and December 31, 2018, the Executive Compensation and Personnel Committee of the Corporation's Board of Directors granted a total of 36,968, 40,978 and 40,108 shares, respectively, of restricted common stock to certain key employees and all independent directors of the Corporation. Compensation expense for the restricted stock awards is recognized over the requisite service period based on the fair value of the shares at the date of grant on a straight-line basis. Non-vested restricted stock awards are recorded as a reduction of additional paid-in-capital in shareholders’ equity until earned. Compensation expense resulting from time-based, performance-based and director restricted stock awards was $1,410, $1,346 and $1,545 for the years ended December 31, 2020, December 31, 2019, and December 31, 2018, respectively. The total income tax benefit related to the recognized compensation cost of vested restricted stock awards was $296, $283 and $324 for the years ended December 31, 2020, 2019 and 2018, respectively. A summary of changes in non-vested restricted stock awards follows: Shares Weighted-average Non-vested at January 1, 2020 58,370 $ 24.96 Granted 25,466 28.64 Vested (27,530) 24.11 Non-vested at December 31, 2020 56,306 $ 27.14 The above table excludes 11,502 shares in restricted stock awards that were granted at a weighted average fair value of $29.56 and immediately vested. As of December 31, 2020 and December 31, 2019, there was $1,055 and $1,026, respectively, of total unrecognized compensation cost related to non-vested shares granted under the restricted stock award plan. The fair value of shares vesting during December 31, 2020, December 31, 2019, and December 31, 2018 was $1,123, $1,462 and $1,535, respectively. In addition to the time-based restricted stock disclosed above, the Corporation’s Board of Directors grants performance-based restricted stock awards ("PBRSAs") to key employees. The number of PBRSAs will depend on certain performance conditions earned over a three year period and are also subject to service-based vesting. In 2020, awards with a maximum of 18,100 shares in aggregate were granted to key employees. In 2019, awards with a maximum of 16,681 shares in aggregate were granted to key employees. In 2018, awards with a maximum of 15,657 shares in aggregate were granted to key employees. In 2019, the 2017 PBRSAs were fully earned and in 2020, 7,109 shares were fully distributed. The fair value of the 7,109 shares distributed in 2020 was $233. Total compensation expense related to the PBRSAs and included in the above compensation expense total was $384, $221 and $314 for 2020, 2019 and 2018. Estimated unearned compensation related to PBRSAs at December 31, 2020 was $539. The number of authorized stock-based awards still available for grant as of December 31, 2020 was 457,448.

Banking and Thrift, Other Disclosures [Abstract]
Capital Requirements and Restrictions on Retained Earnings	Capital Requirements and Restrictions on Retained Earnings Banks and financial holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, for the Bank, prompt corrective action ("PCA") regulations involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can result in regulatory enforcement actions. The net unrealized gain or loss on available for sale securities are excluded from computing regulatory capital. Management believes as of December 31, 2020 the Corporation and the Bank meet all capital adequacy requirements to which they are subject. The PCA regulations provide five capital categories: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms alone do not represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion; brokered deposits may not be accepted, renewed or rolled over; and capital restoration plans are required. As of December 31, 2020 and December 31, 2019, the most recent regulatory notifications categorized the Bank as well capitalized under the PCA regulatory framework. There are no events or conditions since this notification that management believes have changed the Bank’s capital category. Actual and required capital amounts and ratios are presented below as of December 31, 2020 and December 31, 2019. The capital adequacy ratio includes the capital conservation buffer.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Interest Rate Swaps	Interest Rate Swaps On September 7, 2018, the Corporation executed an interest rate swap agreement with a 5-year term and an effective date of September 15, 2018 in order to hedge cash flows associated with $10 million of a subordinated note that was issued by the Corporation during 2007 and elected cash flow hedge accounting for the agreement. The Corporation’s objective in using this derivative is to add stability to interest expense and to manage its exposure to interest rate risk. The interest rate swap involves the receipt of variable-rate amounts in exchange for fixed-rate payments from September 15, 2018 to September 15, 2023 without the exchange of the underlying notional amount. At December 31, 2020, the variable rate on the subordinated debt was 1.80% (LIBOR plus 155 basis points) and the Corporation was paying 4.53% (2.98% fixed rate plus 155 basis points). In order to hedge cash flows associated with $10 million of a subordinated note discussed above, on May 3, 2011, the Corporation executed an interest rate swap agreement with a 5-year term and an effective date of September 15, 2013 and expired September 2018. The Corporation’s objective in using this derivative was to add stability to interest expense and to manage its exposure to interest rate risk. The interest rate swap involved the receipt of variable-rate amounts in exchange for fixed-rate payments from September 15, 2013 to September 15, 2018 without exchange of the underlying notional amount. As of December 31, 2020 and December 31, 2019, no derivatives were designated as fair value hedges or hedges of net investments in foreign operations. Additionally, the Corporation does not use derivatives for trading or speculative purposes and currently does not have any derivatives that are not designated as hedges. The following tables provide information about the amounts and locations of activity related to the interest rate swaps designated as cash flow hedges within the Corporation’s consolidated balance sheet and statement of income as of December 31, 2020 and December 31, 2019 and for the years ended December 31, 2020, December 31, 2019, and December 31, 2018: As of December 31 Liability Derivative Balance Sheet Fair value Location December 31, 2020 December 31, 2019 Interest rate contract Accrued interest payable and other liabilities $(768) $(485) For the Year Ended December 31, 2020 (a) (b) (c) (d) (e) Interest rate contract $(224) Interest expense – subordinated debentures $(224) Other $0 For the Year Ended December 31, 2019 Interest rate contract $(225) Interest expense – subordinated $(63) Other $0 For the Year Ended December 31, 2018 Interest rate contract $(32) Interest expense – subordinated debentures $(164) Other $0 (a) Amount of Gain or (Loss) Recognized in Other Comprehensive Loss on Derivative (Effective Portion), net of tax (b) Location of Gain or (Loss) Reclassified from Accumulated Other Comprehensive Loss into Income (Effective Portion) (c) Amount of Loss Reclassified from Accumulated Other Comprehensive Loss into Income (Effective Portion) (d) Location of Gain or (Loss) Recognized in Income on Derivative (Ineffective Portion and Amount Excluded from Effectiveness Testing) (e) Amount of Gain or (Loss) Recognized in Income on Derivative (Ineffective Portion and Amount Excluded from Effectiveness Testing) Amounts reported in accumulated other comprehensive loss related to the interest rate swap will be reclassified to interest expense as interest payments are made on the subordinated debentures. Such amounts reclassified from accumulated other comprehensive loss to interest expense in the next twelve months are expected to be $273. As of December 31, 2020 and December 31, 2019, a cash collateral balance of $1,050 and $750, respectively, was maintained with the counterparty to the interest rate swaps. These balances are included in interest bearing deposits with other banks on the consolidated balance sheets. The Corporation entered into certain interest rate swap contracts that are not designated as hedging instruments. These derivative contracts relate to transactions in which the Corporation enters into an interest rate swap with a customer while at the same time entering into an offsetting interest rate swap with another financial institution. In connection with each swap transaction, the Corporation agrees to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on a similar notional amount at a fixed interest rate. Concurrently, the Corporation agrees to pay another financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. The transaction allows the Corporation’s customers to effectively convert a variable rate loan to a fixed rate. Because the Corporation acts as an intermediary for its customer, changes in the fair value of the underlying derivative contracts offset each other and do not impact the Corporation’s results of operations. The Corporation pledged cash collateral to another financial institution with a balance $4,873 as of December 31, 2020 and $2,000 as of December 31, 2019. This balance is included in interest bearing deposits with other banks on the consolidated balance sheets. The Corporation may require its customers to post cash or securities as collateral on its program of back-to-back swaps depending upon the specific facts and circumstances surrounding each loan and individual swap. In addition, certain language is included in the International Swaps and Derivatives Association agreement and loan documents where, in default situations, the Corporation is permitted to access collateral supporting the loan relationship to recover any losses suffered on the derivative asset or liability. The Corporation may be required to post additional collateral to swap counterparties in the future in proportion to potential increases in unrealized loss positions. The following table provides information about the amounts and locations of activity related to the back-to-back interest rate swaps within the Corporation’s consolidated balance sheet as of December 31, 2020 and December 31, 2019: Notional Average Weighted Weighted Fair December 31, 2020 3 rd Party interest rate swaps $ 34,089 6.7 4.13 % 1 month LIBOR + 2.27% $ 4,017 (a) Customer interest rate swaps (34,089) 6.7 4.13 % 1 month LIBOR + 2.27% (4,017) (b) December 31, 2019 3 rd Party interest rate swaps $ 35,382 7.7 4.13 % 1 month LIBOR + 2.27% $ 1,877 (a) Customer interest rate swaps (35,382) 7.7 4.13 % 1 month LIBOR + 2.27% (1,877) (b) (a) Reported in accrued interest receivable and other assets within the consolidated balance sheets (b) Reported in accrued interest payable and other liabilities within the consolidated balance sheets

Fair Value Disclosures [Abstract]
Off-Balance Sheet Activities	Off-Balance Sheet Activities Some financial instruments, such as loan commitments, credit lines, letters of credit, and overdraft protection, are issued to meet customer financing needs. These are agreements to provide credit or to support the credit of others, as long as conditions established in the contract are met, and usually have expiration dates. Commitments may expire without being used. Off-balance sheet risk to credit loss exists up to the face amount of these instruments, although material losses are not anticipated. The same credit policies are used to make such commitments as are used for loans, including obtaining collateral at exercise of the commitment. The contractual amount of financial instruments with off-balance sheet risk was as follows at December 31, 2020 and December 31, 2019: December 31, 2020 December 31, 2019 Fixed Rate Variable Rate Fixed Rate Variable Rate Commitments to make loans $ 52,073 $ 266,336 $ 21,375 $ 184,106 Unused lines of credit 24,328 673,919 14,637 446,407 Standby letters of credit 15,301 1,597 14,503 824 Commitments to make loans are generally made for periods of 60 days or less.

Quarterly Financial Information Disclosure [Abstract]
Quarterly Financial Data (Unaudited)	Quarterly Financial Data (Unaudited) The table below sets forth the Corporation's unaudited condensed consolidated quarterly results of operations data for the years ended December 31, 2020 and December 31, 2019 (in thousands, except per share data). In the opinion of management, all adjustments (consisting of normal recurring accruals) that are necessary for a fair presentation of the quarterly results have been reflected in the data. It is also management's opinion, however, that quarterly results of operations data are not indicative of the financial results to be achieved in succeeding years or quarters. In order to obtain a more accurate indication of performance, one should review the financial and operating results, changes in stockholders' equity and cash flows for a period of several years. Beginning with the quarter ended December 31, 2020 the Corporation adopted ASC 326. Prior to the quarter ended December 31, 2020, the results were based on incurred loss methodology and these results have not been restated.

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	Revenue from Contracts with Customers All of the Corporation’s revenue from contracts with customers in the scope of ASC 606 is recognized within Non-Interest Income. The following table presents the Corporation's Non-Interest Income by revenue stream and reportable segment for the years ended December 31, 2020 and December 31, 2019. Items outside the scope of ASC 606 are noted as such. December 31, 2020 December 31, 2019 December 31, 2018 Non-interest Income Service charges on deposit accounts $ 5,095 $ 6,402 $ 5,759 Wealth and asset management fees 5,497 4,627 4,172 Mortgage banking (1) 3,354 1,412 1,019 Card processing and interchange income 5,727 4,641 4,261 Net realized gains on available-for-sale securities (1) 2,190 148 0 Other income 6,196 8,745 5,512 Total non-interest income $ 28,059 $ 25,975 $ 20,723 (1) Not within scope of ASU 2014-9 Management determined that the primary sources of revenue emanating from interest and dividend income on loans and investment securities along with non-interest revenue resulting from security gains, loan servicing, gains on the sale of loans, commitment fees, fees from financial guarantees, certain credit card fees, gains (losses) on sale of other real estate owned not financed by the Corporation, is not within the scope of ASU 2014-9. The types of non-interest income within the scope of the standard that are material to the consolidated financial statements are services charges on deposit accounts, wealth and asset management fee income, card processing and interchange income, and other income. Service charges on deposit accounts : The Corporation earns fees from its deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which include services such as ATM use fees, stop payment charges, statement rendering, and ACH fees, are recognized at the time the transaction is executed, as that is the point in time the Corporation fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Corporation satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Services charges on deposits are withdrawn from the customer’s account balance. Wealth and asset management fees : The Corporation earns wealth and asset management fees from its contracts with trust and brokerage customers to manage assets for investment, and/or to transact on their accounts. These fees are primarily earned over time as the Corporation provides the contracted monthly or quarterly services and are generally assessed based on a tiered scale of the market value of assets under management at month end. Fees for these services are billed to customers on a monthly or quarterly basis and are recorded as revenue at the end of the period for which the wealth and asset management services have been performed. Other performance obligations, such as the delivery of account statements to customers, are generally considered immaterial to the overall transaction price. Card processing and interchange income : The Corporation earns interchange fees from check card and credit card transactions conducted through the Visa payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. Other income : The Corporation's other income includes sources such as bank owned life insurance, changes in fair value and realized gains on sales of trading securities, certain service fees, gains (losses) on sales of fixed assets, and gains (losses) on sale of other real estate owned. The service fees are recognized in the same manner as the service charges mentioned above. While gains (losses) on the sale of other real estate owned are within the scope of ASU 2014-9 if financed by the Corporation, the Corporation does not finance the sale of transactions. The revenue on the sale is recorded upon the transfer of control of the property to the buyer and the other real estate owned asset is derecognized.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Business and Organization	Business and Organization CNB Financial Corporation (the "Corporation") is headquartered in Clearfield, Pennsylvania, and provides a full range of banking and related services through its wholly owned subsidiary, CNB Bank (the "Bank"). In addition, the Bank provides trust and asset management services, including the administration of trusts and estates, retirement plans, and other employee benefit plans as well as a full range of wealth management services. The Bank serves individual and corporate customers and is subject to competition from other financial institutions and intermediaries with respect to these services. In addition to the Bank, the Corporation also operates a consumer discount loan and finance business through its wholly owned subsidiary, Holiday Financial Services Corporation ("Holiday"). The Corporation and its other subsidiaries are subject to examination by federal and state regulators. The Corporation’s market area is primarily concentrated in the central and northwest regions of the Commonwealth of Pennsylvania, the central and northeast regions of the state of Ohio and western New York.
Basis of Financial Presentation	Basis of Financial Presentation The financial statements are consolidated to include the accounts of the Corporation and the Bank, CNB Securities Corporation, Holiday, CNB Risk Management, Inc. and CNB Insurance Agency. All significant intercompany accounts and transactions have been eliminated in the consolidated financial statements. Certain prior period amounts have been reclassified to conform to the current period presentation. Reclassifications had no effect on prior year net income or shareholders’ equity.
Risks and Uncertainties	Risks and Uncertainties The worldwide spread of COVID-19 has created significant uncertainty in the global economy. There have been no comparable recent events that provide guidance as to the effect the spread of COVID-19 as a global pandemic may have, and, as a result, the ultimate impact of COVID-19 and the extent to which COVID-19 and the related government actions impact the Corporation’s business, results of operations and financial condition will depend on future developments, which are highly uncertain and difficult to predict.
Use of Estimates	Use of Estimates To prepare financial statements in conformity with U.S. generally accepted accounting principles ("GAAP"), management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided and future results could differ. The Corporation's business is dependent upon the willingness and ability of its employees and customers to conduct banking and other financial transactions. If the global response to contain the COVID-19 pandemic requires further restricted measures or is unsuccessful, the Corporation could experience a material adverse effect on its business, financial condition, results of operations and cash flows. Since the extent to which the COVID-19 pandemic impacts its operations will depend on future developments that are highly uncertain, the Corporation cannot estimate the impact on its business, financial condition or near or long-term financial or operational results with reasonable certainty. Accordingly, the Corporation is disclosing potentially material items of which it is aware. Asset valuation : Currently, the Corporation does not expect the COVID-19 pandemic to affect its ability to account timely for the assets on its balance sheet; however, this could change in future periods due to any number of potential impacts from the COVID-19 pandemic. The COVID-19 pandemic could cause a further and sustained decline in the Corporation's stock price or the occurrence of what management would deem to be a triggering event that could, under certain circumstances, cause us to perform a goodwill impairment test, resulting in an impairment charge being recorded for that period. In the event that the Corporation concludes that all or a portion of its goodwill is impaired, a non-cash charge for the amount of such impairment would be recorded to earnings. Such a charge would have no impact on tangible capital or regulatory capital. Credit : The Corporation is working with customers directly affected by the COVID-19 pandemic. The Corporation has offered assistance in accordance with regulator guidelines. As a result of the current economic slowdown related to the COVID-19 pandemic, the Corporation is engaging in more frequent communication with borrowers to better understand their situation and the challenges faced, allowing it to respond proactively as needs and issues arise.
Operating Segments	Operating Segments While the chief decision-makers monitor the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Corporation-wide basis, and operating segments are aggregated into one as operating results for all segments are similar. Accordingly, all of the financial service operations are considered by management to be aggregated in one reportable operating segment.
Cash and Cash Equivalents	Cash and Cash Equivalents For purposes of the consolidated statement of cash flows, the Corporation defines cash and cash equivalents as cash and due from banks, interest bearing deposits with other banks, and Federal funds sold. Net cash flows are reported for customer loan and deposit transactions, interest bearing time deposits with other banks and borrowings with original maturities of 90 days or less.
Restrictions on Cash	Restrictions on Cash Note 20, "Interest Rate Swaps," to the consolidated financial statements discloses the cash collateral balances required to be maintained in connection with the Corporation’s interest rate swaps.
Debt Securities/Allowance for Credit Losses	Debt Securities When purchased, debt securities are classified as held to maturity, trading or available for sale. Debt securities are classified as held to maturity when the Corporation has the positive intent and ability to hold the securities to maturity. Held to maturity securities are carried at amortized cost. Debt securities are classified as trading when purchased principally for the purpose of selling them in the near term, or when the fair value option has been elected. Trading securities are recorded at fair value with changes in fair value included in earnings in non-interest income. Available for sale securities ("AFS") are those securities not classified as held to maturity or trading and are carried at their fair value. Unrealized gains and losses, net of deferred tax, on securities classified as available for sale are recorded as other comprehensive income. Management has not classified any debt securities as held to maturity. Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are generally amortized on the level-yield method without anticipating prepayments, except for mortgage-backed securities where prepayments are anticipated. Premiums on callable debt securities are amortized to their earliest call date. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific-identification method. The Corporation has made a policy election to exclude accrued interest from the amortized cost basis of debt securities and report accrued interest separately in accrued interest receivable and other assets in the consolidated balance sheets. A debt security is placed on nonaccrual status at the time any principal or interest payments become more than 90 days delinquent or if full collection of interest or principal becomes uncertain. Accrued interest for a security placed on nonaccrual is reversed against interest income. There was no accrued interest related to debt securities reversed against interest income for the year ended December 31, 2020. Allowance for Credit Losses (Debt Securities Available-for Sale) For available-for-sale debt securities in an unrealized loss position, the Corporation first assesses whether it intends to sell, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security's amortized cost basis is written down to fair value through income. For debt securities available-for-sale that do not meet the aforementioned criteria, the Corporation evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the allowance when management confirms that an available-for-sale security is uncollectable or when either of the criteria regarding intent or requirement to sell is met. As of December 31, 2020, the Corporation determined that the unrealized loss positions in available-for-sale debt securities were not the result of credit losses, and therefore, an allowance for credit losses was not recorded. See Note 3, "Debt Securities," and Note 6, "Fair Value Measurements," for more information about available-for-sale debt securities. Accrued interest receivable on available-for-sale debt securities totaled $2.2 million at December 31, 2020 and is excluded from the estimate of credit losses.
Loans Held for Sale	Loans Held for Sale 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 rights retained. The carrying value of the mortgage loan sold is reduced by the amount allocated to the servicing right. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold.
Loans	Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost. Amortized cost is the principal balance outstanding, net of purchase premiums and discounts, deferred loan fees and costs. Accrued interest receivable totaled $15.4 million at December 31, 2020 and was reported in Accrued interest receivable and other assets on the consolidated balance sheets and is excluded from the estimate of credit losses. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income using the level-yield method without anticipating prepayments. Interest income on mortgage and commercial loans is discontinued and placed on nonaccrual status at the time the loan is 90 days delinquent unless the loan is well secured and in process of collection. Consumer loans continue to accrue interest until they are recorded as charge-offs no later than 180 days past due unless the loan is in the process of collection. Past-due status is based on the contractual terms of the loan. Loans, including loans modified in a troubled debt restructuring, are placed on nonaccrual or recorded as charge-offs at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not received on loans placed on nonaccrual is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Under the cost-recovery method, interest income is not recognized until the loan balance is reduced to zero. Under the cash-basis method, interest income is recorded when the payment is received in cash. For all portfolio segments, loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Purchased Credit Deteriorated ("PCD") Loans	Purchased Credit Deteriorated ("PCD") Loans The Corporation has purchased loans, some of which have experienced more than insignificant credit deterioration since origination. PCD loans are recorded at the amount paid. An allowance for credit losses is determined using the same methodology as other loans held for investment. The initial allowance for credit losses determined on a collective basis is allocated to individual loans. The sum of the loan's purchase price and allowance for credit losses becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent changes to the allowance for credit losses are recorded through provision expense.
Troubled Debt Restructurings (“TDRs”)	Troubled Debt Restructurings ("TDRs") Loans are classified as TDRs when a borrower is experiencing financial difficulty and the Corporation has granted a concession that would not have otherwise been made for a borrower with similar credit characteristics. Prior to granting a modification, the borrower's ability to repay the loan is evaluated, including: current income levels and debt to income ratio, credit score, payment history and an evaluation of secondary repayment sources, if any is updated. The Corporation's policy is to modify loans typically through a payment reduction or through an interest rate reduction for a specified period of time, usually six to twelve months. Interest-only payments may also be approved during the modification period. Principal forgiveness is generally not an option for modification. The allowance for credit loss on a TDR is measured using the same method as all other loans held for investment, except the original interest rate is used to discount the expected cash flows, not the rate specified within the restructuring. When there is a reasonable expectation, at the reporting date, that a TDR will be executed with a borrower the estimated life of the TDR reflects the extension or renewal. Before granting approval to modify a loan in a TDR, the borrower’s ability to repay is evaluated, including: current income levels and debt to income ratio, borrower’s credit score, payment history of the loan and updated evaluation of the secondary repayment source. The Corporation also modifies some loans that are not classified as TDRs as the modification is due to a restructuring where the effective interest rate on the debt is reduced to reflect a decrease in market interest rates. The Corporation's allowance for credit losses reflects the effects of a TDR when management reasonably expects at the reporting date that a TDR will be executed with an individual borrower. The Corporation has implemented various consumer and commercial loan modification programs to provide its borrowers relief from the economic impacts of COVID-19. In accordance with the CARES Act, loans to borrowers experiencing financial difficulty related to the COVID-19 pandemic which were granted short-term modifications after March 1, 2020 and which were not more than 30 days past due as of December 31, 2019 are exempt from TDR classification. In addition, for loans modified in response to the COVID-19 pandemic that do not meet the above delinquency criteria (e.g., more than 30 days past due as of December 31, 2019), the Corporation applies the guidance included in an interagency statement issued by the bank regulatory agencies. This guidance states that loan modifications performed in light of the COVID-19 pandemic, including loan payment deferrals that are up to six months in duration, that were granted to borrowers who were less than 30 days past due as of the implementation date of a loan modification program are exempt from TDR classification. For loan modifications that include a payment deferral and are not TDRs, the borrower’s past due and nonaccrual status will not be impacted during the deferral period. Interest income will continue to be recognized over the contractual life of the loan.
Concentration of Credit Risk	Concentration of Credit Risk Most of the Corporation’s business activity is with customers located within the Commonwealth of Pennsylvania and the states of Ohio and New York. Therefore, the Corporation’s exposure to credit risk is significantly affected by changes in the economies of Pennsylvania, Ohio, and New York.
Allowance for Loan Losses	Allowance for Credit Losses - Loans The allowance for credit losses on loans represents management’s estimate of expected credit losses over the estimated life of our existing portfolio of loans. The allowance for credit losses is a valuation account that is deducted from the loan's amortized cost basis to present the net amount expected to be collected on the loans. The expense for credit loss recorded through earnings is the amount necessary to maintain the allowance for credit losses on loans at the amount of expected credit losses inherent within the loan portfolio. Loans are recorded as charge-offs against the allowance when management confirms a loan balance is uncollectable. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Management estimates the allowance balance using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts, and other significant qualitative and quantitative factors. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, changes in environmental conditions, delinquency level, segment growth rates and changes in duration within new markets, or other relevant factors. For further information on the ACL on loans, see Note 4, "Loans," for additional detail. The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist. The Corporation has segregated its portfolio segments based on federal call report codes which classify loans based on the primary collateral supporting the loan. The following are the Corporation's segmented portfolios: 1-4 Family Construction : The Bank originates construction loans to finance 1-4 family residential buildings. Construction loans include not only construction of new structures, but also additions or alterations to existing structures and the demolition of existing structures to make way for new structures. Construction loans are generally secured by real estate. The primary risk characteristics are specific to the uncertainty on whether the construction will be completed according to the specifications and schedules. Factors that may influence the completion of construction may be customer specific, or related to changes in general economic conditions. Other construction loans and all land development and other land loans : The Bank originates construction loans to finance land development preparatory to erecting new structures or the on-site construction of industrial, commercial, or multi-family buildings. Construction loans include not only construction of new structures, but also additions or alterations to existing structures and the demolition of existing structures to make way for new structures. Construction loans are generally secured by real estate. The primary risk characteristics are specific to the uncertainty on whether the construction will be completed according to the specifications and schedules. Factors that may influence the completion of construction may be customer specific, such as the quality and depth of property management, or related to changes in general economic conditions. Farmland (including farm residential and other improvements) : The Bank originates loans secured by farmland and improvements thereon, secured by mortgages. Farmland includes all land known to be used or usable for agricultural purposes, such as crop and livestock production. Farmland also includes grazing or pasture land, whether tillable or not and whether wooded or not. The primary risk characteristics are specific to the uncertainty on production, market, financial, environmental and human resources. Home equity lines of credit : The primary risk characteristics associated with home equity lines of credit typically involve changes to the borrower, including unemployment or other loss of income; unexpected significant expenses, such as major medical expenses, catastrophic events, divorce and death. Home equity lines of credit are typically originated with variable or floating interest rates, which could expose the borrower to higher payments in a rising interest rate environment. Real estate values could decrease and cause the value of the underlying property to fall below the loan amount, creating additional potential loss exposure for the Bank. Residential Mortgages secured by first liens : The Bank originates one-to-four family residential mortgage loans primarily within central and northwest Pennsylvania, central and northeast Ohio and western New York. These loans are secured by first liens on a primary residence or investment property. The primary risk characteristics associated with residential mortgage loans typically involve major changes to the borrower, including unemployment or other loss of income; unexpected significant expenses, such as major medical expenses, catastrophic events, divorce or death. Residential mortgage loans that have adjustable rates could expose the borrower to higher payments in a rising interest rate environment. Real estate values could decrease and cause the value of the underlying property to fall below the loan amount, creating additional potential loss exposure for the Bank. Residential Mortgages secured by junior liens : The Bank originates loans secured by junior liens against one to four family properties primarily within central and northwest Pennsylvania, central and northeast Ohio and western New York. Loans secured by junior liens are primarily in the form of an amortizing home equity loan. These loans are subordinate to a first mortgage which may be from another lending institution. The primary risk characteristics associated with loans secured by junior liens typically involve major changes to the borrower, including unemployment or other loss of income, unexpected significant expenses, such as for major medical expenses, catastrophic events, divorce or death. Real estate values could decrease and cause the value of the property to fall below the loan amount, creating additional potential loss exposure for the Bank. Multifamily (5 or more) residential properties : The Bank originates mortgage loans for multifamily properties primarily within central and northwest Pennsylvania, central and northeast Ohio and western New York. Multifamily loans are expected to be repaid from the cash flows of the underlying property so the collective amount of rents must be sufficient to cover all operating expenses, property management and maintenance, taxes and debt service. Increases in vacancy rates, interest rates or other changes in general economic conditions can have an impact on the borrower and its ability to repay the loan. Owner-occupied, nonfarm nonresidential properties : The Bank originates mortgage loans to operating companies primarily within central and northwest Pennsylvania, central and northeast Ohio and western New York. Owner-occupied real estate properties primarily include retail buildings, medical buildings and industrial/warehouse space. Owner-occupied loans are typically repaid first by the cash flows generated by the borrower’s business operations. The primary risk characteristics are specific to the underlying business and its ability to generate sustainable profitability and positive cash flow. Factors that may influence a borrower's ability to repay their loan include demand for the business’ products or services, the quality and depth of management, the degree of competition, regulatory changes, and general economic conditions. Non-owner occupied, nonfarm nonresidential properties : The Bank originates mortgage loans for commercial real estate that is managed as an investment property primarily within central and northwest Pennsylvania, central and northeast Ohio and western New York. Commercial real estate properties primarily include retail buildings/shopping centers, hotels, office/medical buildings and industrial/warehouse space. Increases in vacancy rates, interest rates or other changes in general economic conditions can have an impact on the borrower and its ability to repay the loan. Commercial real estate loans are generally considered to have a higher degree of credit risk as they may be dependent on the ongoing success and operating viability of a fewer number of tenants who are occupying the property and who may have a greater degree of exposure to economic conditions. Agricultural production and other loans to farmers : The Bank originates loans secured or unsecured to farm owners and operators (including tenants) or to nonfarmers for the purpose of financing agricultural production, including the growing and storing of crops, the marketing or carrying of agricultural products by the growers thereof, and the breeding, raising, fattening, or marketing of livestock, and for purchases of farm machinery, equipment, and implements. The primary risk characteristics are specific to the uncertainty on production, market, financial, environmental and human resources. Commercial and Industrial : The Bank originates lines of credit and term loans to operating companies for business purposes. The loans are generally secured by business assets such as accounts receivable, inventory, business vehicles and equipment as well as the stock of a company, if privately held. Commercial and Industrial loans are typically repaid first by the cash flows generated by the borrower’s business operations. The primary risk characteristics are specific to the underlying business and its ability to generate sustainable profitability and positive cash flow. Factors that may influence a borrower's ability to repay their loan include demand for the business’ products or services, the quality and depth of management, the degree of competition, regulatory changes, and general economic conditions. The ability of the Bank to foreclose and realize sufficient value from business assets securing these loans is often uncertain. To mitigate the risk characteristics of commercial and industrial loans, commercial real estate may be included as a secondary source of collateral. The Bank will often require more frequent reporting requirements from the borrower in order to better monitor its business performance. Credit cards : The Bank originates credit cards offered to individuals and businesses for household, family, other personal and business expenditures. Credit cards generally are floating rate loans and include both unsecured and secured lines. Credit card loans generally do not have stated maturities and are unconditionally cancellable. The primary risk characteristics associated with credit cards typically involve major changes to the borrower, including unemployment or other loss of income, unexpected significant expenses, such as for major medical expenses, catastrophic events, divorce or death. Other revolving credit plans : The Bank originates lines of credit to individuals for household, family, and other personal expenditures. Consumer loans generally have higher interest rates and shorter terms than residential loans but tend to have higher credit risk due to the type of collateral securing the loan or in some cases the absence of collateral. The primary risk characteristics associated with other revolving loans typically involve major changes to the borrower, including unemployment or other loss of income, unexpected significant expenses, such as for major medical expenses, catastrophic events, divorce or death. Automobile : The Bank originates consumer loans extended for the purpose of purchasing new and used passenger cars and other vehicles such as minivans, vans, sport-utility vehicles, pickup trucks, and similar light trucks for personal use. The primary risk characteristics associated with automobile loans typically involve major changes to the borrower, including unemployment or other loss of income, unexpected significant expenses, such as for major medical expenses, catastrophic events, divorce or death. Other consumer : The Bank originates loans to individuals for household, family, and other personal expenditures. This also represents all other loans that cannot be categorized in any of the previous mentioned consumer loan segments. Consumer loans generally have higher interest rates and shorter terms than residential loans but tend to have higher credit risk due to the type of collateral securing the loan or in some cases the absence of collateral. The primary risk characteristics associated with automobile loans typically involve major changes to the borrower, including unemployment or other loss of income, unexpected significant expenses, such as for major medical expenses, catastrophic events, divorce or death. Obligations (other than securities and leases) of states and political subdivisions : The Bank originates various types of loans made directly to municipalities. These loans are repaid through general cash flows or through specific revenue streams, such as water and sewer fees. The primary risk characteristics associated with municipal loans are the municipalities ability to manage cash flow, balance the fiscal budget, fixed asset and infrastructure requirements. Additional risks include changes in demographics, as well as social and political conditions. Other loans : The Bank originates other loans, such as loans to nonprofit organizations, including churches, hospitals, educational and charitable institutions, clubs, and similar associations. The primary risk characteristics associated with these types of loans are repayment, demographic, social, political and reputation risks. Overdrafts : The Bank reports overdrawn customer deposit balances as loans. Methods utilized by management to estimate expected credit losses include a discounted cash flow ("DCF") model that discounts instrument-level contractual cash flows, adjusted for prepayments and curtailments, incorporating loss expectations, and a weighted average remaining maturity ("WARM") model which contemplates expected losses at a pool-level, utilizing historic loss information. Under both models, management estimates the allowance for credit losses on loans using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. After the end of the reasonable and supportable forecast period, the loss rates revert to the mean loss rate over a period of eight quarters. Historical credit loss experience, including examination of loss experience at representative peer institutions when the Corporation’s loss history does not result in estimations that are meaningful to users of the Corporation’s Consolidated Financial Statements, provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, changes in environmental conditions, delinquency level, segment growth rates and changes in duration within new markets, or other relevant factors. The DCF model uses inputs of current and forecasted macroeconomic indicators to predict future loss rates. The current macroeconomic indicator utilized by the Corporation is the Federal unemployment rate and the S&P/Case-Shiller U.S. National Home Price Index for select collective residential related pools. In building the CECL methodology utilized in the DCF model, a correlation between this indicator and historic loss levels was developed, enabling a prediction of future loss rates related to future Federal unemployment rates and S&P/Case-Shiller U.S. National Home Price Index. The portfolio segments utilizing the DCF methodology comprised 90.8% of the amortized cost of loans as of December 31, 2020, and included: • Farmland • Home equity lines of credit • Residential Mortgages secured by first liens • Residential Mortgages secured by junior liens • Multifamily (5 or more) residential properties • Owner-occupied, nonfarm nonresidential properties • Non-owner occupied, nonfarm nonresidential properties • Agricultural production and other loans to farmers • Commercial and Industrial • Automobile • Obligations (other than securities and leases) of states and political subdivisions • Other loans The WARM model uses combined historic loss rates for the Corporation and peer institutions, if necessary, gathered from call report filings. The selected period for which historic loss rates are used is dependent on management's evaluation of current conditions and expectations of future loss conditions. The portfolio segments utilizing the WARM methodology comprised 9.2% of the amortized cost of loans as of December 31, 2020, and included: • 1-4 Family Construction • Other construction loans and all land development and other land loans • Credit cards • Other revolving credit plans • Other consumer Loans that do not share risk characteristics are evaluated on an individual basis. Loans evaluated individually are not also included in the collective evaluation and typically represent collateral dependent loans but may also include other non-performing loans or TDRs. The Corporation uses the practical expedient to measure individually evaluated loans as collateral dependent and/or when repayment is expected to be provided substantially through the operation or sale of the collateral. Expected credit losses are based on the fair value at the reporting date, adjusted for selling costs as appropriate. For collateral dependent loans, credit loss is measured as the difference between the amortized cost basis in the loan and the fair value of the underlying collateral. The fair value of the collateral is adjusted for the estimated cost to sell if repayment or satisfaction of a loan is dependent on the sale (rather than only on the operation) of the collateral. Allowance for Credit Losses on Off-Balance Sheet ("OBS") Credit Exposures Management estimates expected credit losses over the contractual period in which the Corporation is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Corporation. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life. Management estimates the amount of expected losses by calculating a commitment usage factor over the contractual period for exposures that are not unconditionally cancellable by the Bank and applying the loss factors used in the allowance for credit losses on loans methodology to the results of the usage calculation to estimate the liability for credit losses related to unfunded commitments for each loan segment. The estimate of credit losses on OBS credit exposures is not material at December 31, 2020.
Federal Home Loan Bank Stock	Federal Home Loan Bank Stock As a member of the Federal Home Loan Bank ("FHLB") of Pittsburgh, the Corporation is required to purchase and hold stock in the FHLB to satisfy membership and borrowing requirements. This stock is restricted in that it can only be sold to the FHLB or to another member institution, and all sales of FHLB stock must be at par. As a result of these restrictions, FHLB stock is unlike other investment securities insofar as there is no trading market for FHLB stock and the transfer price is determined by FHLB membership rules and not by market participants. FHLB stock is held as a long-term investment, is valued at its cost basis and is analyzed for impairment based on the ultimate recoverability of the par value. The Company evaluates impairment quarterly. The decision of whether impairment exists is a matter of judgment that reflects our view of the FHLB’s long-term performance, which includes factors such as the following: • its operating performance; • the severity and duration of declines in the fair value of its net assets related to its capital stock amount; • its commitment to make payments required by law or regulation and the level of such payments in relation to its operating performance; • the impact of legislative and regulatory changes on the FHLB, and accordingly, on the members of FHLB; and • its liquidity and funding position.
Foreclosed Assets	Foreclosed AssetsForeclosed assets are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. Physical possession of residential real estate property collateralizing a consumer mortgage loan occurs when legal title is obtained upon completion of foreclosure or when the borrower conveys all interest in the property to satisfy the loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. If fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Operating costs after acquisition are expensed.
Premises and Equipment	Premises and Equipment Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. Depreciation of premises and equipment is computed principally by the straight line method. In general, useful lives range from 3 to 39 years with lives for furniture, fixtures and equipment ranging from 3 to 10 years and lives of buildings and building improvements ranging from 15 to 39 years. Amortization of leasehold improvements is computed using the straight-line method over useful lives of the leasehold improvements or the term of the lease, whichever is shorter. Maintenance, repairs and minor renewals are charged to expense as incurred.
Bank Owned Life Insurance	Bank Owned Life Insurance The Corporation has purchased life insurance policies on certain key employees. Bank-owned life insurance 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.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill resulting from business combinations prior to January 1, 2009 represents the excess of the purchase price over the fair value of the net assets of businesses acquired. Goodwill resulting from business combinations after January 1, 2009 is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interest in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually or more frequently if events and circumstances exists that indicate that a goodwill impairment test should be performed. The Corporation has no intangible assets with an indefinite useful life. The Corporation has selected December 31 as the date to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on the Corporation’s balance sheet. Other intangible assets consist of core deposit intangible assets arising from the acquisition of FC Banc Corp. in 2013, Lake National Bank in 2016 and Bank of Akron in 2020. The core deposit intangible assets from these acquisitions are amortized using an accelerated method over their estimated useful lives, which range from four years to ten years, respectively.
Long-term Assets	Long-term Assets Premises and equipment, goodwill and other intangible assets, and other long-term assets are reviewed for impairment when events indicate their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value.
Loan Commitments and Related Financial Instruments	Loan Commitments and Related Financial Instruments Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.
Derivatives	Derivatives Derivative financial instruments are recognized as assets or liabilities at fair value. The Corporation has interest rate swap agreements which are used as part of its asset liability management to help manage interest rate risk. The Corporation does not use derivatives for trading purposes. At the inception of a derivative contract, the Corporation designates the derivative as one of three types based on the Corporation's intentions and belief as to likely effectiveness as a hedge. These three types are (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment ("fair value hedge"), (2) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability ("cash flow hedge"), or (3) an instrument with no hedging designation ("stand-alone derivative"). For a fair value hedge, the gain or loss on the derivative, as well as the offsetting loss or gain on the hedged item attributable to the hedged risk, are recognized in current earnings as fair values change. For a cash flow hedge, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same periods during which the hedged transaction affects earnings. Changes in the fair value of derivatives that do not qualify for hedge accounting are reported currently in earnings, as non-interest income. Net cash settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in non-interest income. Cash flows on hedges are classified in the cash flow statement the same as the cash flows of the items being hedged. The Corporation formally documents the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions, at the inception of the hedging relationship. This documentation includes linking fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Corporation also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used are highly effective in offsetting changes in fair values or cash flows of the hedged items. The Corporation discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm, or treatment of the derivative as a hedge is no longer appropriate or intended. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as non-interest income. When a fair value hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted over the remaining life of the asset or liability. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that were accumulated in other comprehensive income are amortized into earnings over the same periods which the hedged transactions will affect earnings.
Mortgage Servicing Rights	Mortgage Servicing Rights When mortgage loans are sold with servicing retained, servicing rights are initially recorded at fair value with the income statement effect recorded in mortgage banking income. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. The Corporation compares the valuation model inputs and results to published industry data in order to validate the model results and assumptions. All classes of servicing assets are subsequently measured using the amortization method which requires servicing rights to be amortized into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans. Servicing rights are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is determined by stratifying rights into groupings based on predominant risk characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. If the Corporation later determines that all or a portion of the impairment no longer exists for a particular grouping, a reduction of the allowance may be recorded as an increase to income. Changes in valuation allowances are reported with mortgage banking income on the income statement. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses. Servicing fee income, which is reported on the income statement as mortgage banking income, is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. The amortization of mortgage servicing rights is netted against loan servicing fee income. Late fees and ancillary fees related to loan servicing are not material.
Treasury Stock	Treasury Stock The purchase of the Corporation’s common stock is recorded at cost. Purchases of the stock are made in the open market based on market prices. At the date of subsequent reissue, the treasury stock account is reduced by the cost of such stock on a first-in-first-out basis.
Stock-Based Compensation	Stock-Based Compensation Compensation cost is recognized for restricted stock awards issued to employees, based on the fair value of these awards at the date of grant. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. The Corporation's accounting policy is to recognize forfeitures as they occur.
Comprehensive Income	Comprehensive Income The Corporation presents comprehensive income as part of the Consolidated Statements of Income and Comprehensive Income. Other comprehensive income and loss consists of unrealized holding gains and losses on the available for sale securities portfolio, changes in the unrecognized actuarial gain and transition obligation related to the Corporation’s post retirement benefits plans, and changes in the fair value of the Corporation’s interest rate swaps, net of tax.
Income Taxes	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.
Retirement Plans	Retirement Plans The Corporation’s expense associated with its 401(k) plan is determined under the provisions of the plan document and includes both matching and profit sharing components. Deferred compensation and supplemental retirement plan expenses allocate the benefits over years of service.
Earnings Per Common Share	Earnings Per Common Share Basic earnings per common share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the applicable period, excluding outstanding participating securities. Diluted earnings per common share is computed using the weighted average number of common shares determined for the basic computation plus the dilutive effect of potential common shares issuable under certain stock compensation plans. Unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and are included in the computation of earnings per share pursuant to the two-class method. The Corporation has determined that its outstanding non-vested stock awards are participating securities.
Loss Contingencies	Loss ContingenciesLoss 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 now are such matters that will have a material effect on the financial statements.
Adoption of New/Effects of Newly Issued But Not Yet Effective Accounting Standards	Adoption of New Accounting Standards On January 1, 2020, the Corporation adopted ASU 2016-13 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , which replaces the incurred loss methodology with an expected loss methodology that is referred to as the CECL methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments. standby letters of credit, financial guarantees, and other similar instruments) and net investments in leases recognized by a lessor in accordance with Topic 842 on leases. In addition, ASC 326 made changes to the accounting for available-for-sale debt securities. One such change is to require credit losses to be presented as an allowance rather than as a write-down on available-for-sale debt securities management does not intend to sell or believes that it is more likely than not they will be required to sell. The Corporation adopted ASC 326 using the modified retrospective approach method for all financial assets measured at amortized cost and OBS credit exposures. Results for reporting periods beginning after January 1, 2020 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. In conjunction with the adoption of CECL, the Corporation has revised its segmentation to align with the methodology applied in determining the ACL for loans under CECL, which is based on federal call report codes which classify loans based on the primary collateral supporting the loan. Segmentation prior to the adoption of CECL was based on product type or purpose. Upon adoption, the Corporation's total allowance for credit losses increased by $5.0 million, or 25.5%. The increase in the total allowance for credit losses resulted in a $3.4 million decrease to retained earnings, net of deferred taxes. The overall change in total allowance for credit losses upon adoption was primarily due to the move to a life of loan reserve estimate as well as methodology changes required under CECL. The Corporation adopted ASC 326 using the prospective transition approach for financial assets purchased with credit deterioration that were previously classified as purchased credit impaired ("PCI") and accounted for under ASC 310-30. In accordance with the standard, management did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. On January 1, 2020, the amortized cost basis of the PCD assets were adjusted to reflect the addition of $670 thousand of the allowance for credit losses. The remaining noncredit discount (based on the adjusted amortized cost basis) will be accreted into interest income at the effective interest rate as of January 1, 2020. The following tables illustrates the impact of ASC 326.

ASU 2017-04 simplifies the accounting for goodwill impairment for all entities by requiring impairment charges to be based on the first step in the previous two-step impairment test. Under the new guidance, if a reporting unit’s carrying amount exceeds its fair value, an entity will record an impairment charge based on that difference. The impairment charge will be limited to the amount of goodwill allocated to that reporting unit. The standard eliminates the prior requirement to calculate a goodwill impairment charge using Step 2, which requires an entity to calculate any impairment charge by comparing the implied fair value of goodwill with its carrying amount. ASU 2017-04 was effective for the Corporation on January 1, 2020 and did not have a material impact on the Corporation's financial statements. In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement." ASU 2018-13 modifies disclosure requirements on fair value measurements based on the concepts in the Concepts Statement, including the consideration of costs and benefits. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. ASU 2018-13 was effective for the Corporation on January 1, 2020 and did not have a material impact on the Corporation's financial statement disclosures. In August 2018, the FASB issued ASU 2018-14, "Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans." ASU 2018-14 amends ASC 715-20, "Compensation - Retirement Benefits - Defined Benefit Plans - General." The amended guidance modifies the disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans by removing and adding certain disclosures for these plans. The eliminated disclosures include (a) the amounts in accumulated Other Comprehensive Income expected to be recognized in net periodic benefit costs over the next fiscal year, and (b) the effects of a one percentage point change in assumed health care cost trend rates on the net periodic benefit costs and the benefit obligation for post-retirement health care benefits. Additional disclosures include descriptions of significant gains and losses affecting the benefit obligation for the period. ASU 2018-14 was effective for the Corporation on January 1, 2020 and did not have a material impact on the Corporation's financial statement disclosures. In August 2018, the FASB issued ASU 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) - Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract" ("ASU 2018-15"). ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by these amendments. ASU 2018-15 was effective for the Corporation on January 1, 2020 and did not have a material impact on the Corporation's financial statements. Effects of Newly Issued But Not Yet Effective Accounting Standards In December 2019, the FASB issued ASU 2019-12 "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes." These amendments remove specific exceptions to the general principles in Topic 740 in GAAP. It eliminates the need for an organization to analyze whether the following apply in a given period: exception to the incremental approach for intraperiod tax allocation; exceptions to accounting for basis differences where there are ownership changes in foreign investments; and exception in interim period income tax accounting for year-to-date losses that exceed anticipated losses. It also improves financial statement preparers' application of income tax- related guidance and simplifies GAAP for: franchise taxes that are partially based on income; transactions with a government that result in a step up in the tax basis of goodwill; separate financial statements of legal entities that are not subject to tax; and enacts changes in tax laws in interim periods. The guidance is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted. The Corporation is currently evaluating the impact of ASU 2019-12 on the Corporation's consolidated financial statements. In March 2020, the FASB issued ASU No. 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." The amendments in this update provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. It provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this update are effective for all entities as of March 12, 2020 through December 31, 2022. The Corporation is currently evaluating the impact of the reference rate reform on the Corporation's consolidated financial statements.
Fair Value of Financial Instruments	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 the estimates.
Reclassifications	Reclassifications Certain amounts appearing in the financial statements and notes thereto for prior periods have been reclassified to conform with the current presentation. The reclassifications had no effect on net income or stockholders’ equity as previously reported.

Unaudited Quarterly Results of Operations	The table below sets forth the Corporation's unaudited condensed consolidated quarterly results of operations data for the years ended December 31, 2020 and December 31, 2019 (in thousands, except per share data). In the opinion of management, all adjustments (consisting of normal recurring accruals) that are necessary for a fair presentation of the quarterly results have been reflected in the data. It is also management's opinion, however, that quarterly results of operations data are not indicative of the financial results to be achieved in succeeding years or quarters. In order to obtain a more accurate indication of performance, one should review the financial and operating results, changes in stockholders' equity and cash flows for a period of several years. Beginning with the quarter ended December 31, 2020 the Corporation adopted ASC 326. Prior to the quarter ended December 31, 2020, the results were based on incurred loss methodology and these results have not been restated.
