NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF CONSOLIDATION – NATURE OF OPERATIONS – The Corporation provides banking and related services to individual and corporate customers. Lending products include commercial, mortgage and consumer loans, as well as specialized instruments such as commercial letters-of-credit. Deposit products include various types of checking accounts, passbook and statement savings, money market accounts, interest checking accounts, Individual Retirement Accounts and certificates of deposit. The Corporation provides wealth management services through its trust department, including administration of trusts and estates, retirement plans, and other employee benefit plans, and investment management services. The Corporation offers a variety of personal and commercial insurance products through C&N Financial Services Corporation. C&N Financial Services Corporation also offers mutual funds, annuities, educational savings accounts and other investment products through registered agents. Management has determined that the Corporation has one reportable segment, “Community Banking.” All of the Corporation’s activities are interrelated, and each activity is dependent and assessed based on how each of the activities of the Corporation supports the others. The Corporation is subject to competition from other financial institutions. It is also subject to regulation by certain federal and state agencies and undergoes periodic examination by those regulatory authorities. As a consequence, the Corporation’s business is particularly susceptible to being affected by future federal and state legislation and regulations. USE OF ESTIMATES – Material estimates that are particularly susceptible to change include: (1) the allowance for loan losses and (2) fair values of available-for-sale debt securities based on estimates from independent valuation services or from brokers. INVESTMENT SECURITIES – Available-for-sale debt securities – Other-than-temporary impairment – Marketable equity security Restricted equity securities DERIVATIVES – LOANS HELD FOR SALE – LOANS RECEIVABLE – The loans receivable portfolio is segmented into residential mortgage, commercial and consumer loans. The residential mortgage segment includes the following classes: first and junior lien residential mortgages, home equity lines of credit and residential construction loans. The most significant classes of commercial loans are commercial loans secured by real estate, non-real estate secured commercial and industrial loans, loans to political subdivisions, commercial construction, multi-family residential and loans secured by farmland. Loans are placed on nonaccrual status for all classes of loans when, in the opinion of management, collection of interest is doubtful. Any unpaid interest previously accrued on those loans is reversed from income. Interest income is not recognized on specific impaired loans unless the likelihood of further loss is remote. Interest payments received on loans for which the risk of further loss is greater than remote are applied as a reduction of the loan principal balance. Interest income on other nonaccrual loans is recognized only to the extent of interest payments received. Generally, loans 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 PURCHASED LOANS – 90 days The excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable yield and is recognized into interest income over the remaining life of the loan. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the nonaccretable yield. The nonaccretable yield represents estimated future credit losses expected to be incurred over the life of the loan. Subsequent decreases to the expected cash flows require us to evaluate the need for an allowance for credit losses. Subsequent improvements in expected cash flows result in the reversal of a corresponding amount of the nonaccretable yield which we then reclassify as accretable yield that is recognized into interest income over the remaining life of the loan using the interest method. Our evaluation of the amount of future cash flows that we expect to collect is performed in a similar manner as that used to determine our allowance for credit losses. Charge-offs of the principal amount on acquired loans would be first applied to the nonaccretable yield portion of the fair value adjustment. ALLOWANCE FOR LOAN LOSSES – 120 days The allowance for loan losses is maintained at a level considered adequate to provide for losses that can be reasonably anticipated. Management performs a quarterly evaluation of the adequacy of the allowance. The allowance is based on the Corporation’s past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral, composition of the loan portfolio, current economic conditions and other relevant factors. This evaluation is inherently subjective as it requires material estimates that may be susceptible to significant revision as more information becomes available. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Corporation’s allowance for loan losses. Such agencies may require the Corporation to recognize adjustments to the allowance based on their judgments of information available to them at the time of their examination. In the process of evaluating the loan portfolio, management also considers the Corporation’s exposure to losses from unfunded loan commitments. As of December 31, 2021 and 2020, management determined that no allowance for credit losses related to unfunded loan commitments was required. The allowance consists primarily of two major components – (1) a specific component based on a detailed assessment of certain larger loan relationships, mainly commercial purpose, determined on a loan-by-loan basis; and (2) a general component for the remainder of the portfolio based on a collective evaluation of pools of loans with similar risk characteristics. The general component is assigned to each pool of loans based on both historical net charge-off experience, and an evaluation of certain qualitative factors. An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the above methodologies for estimating specific and general losses in the portfolio. The specific component relates to loans that are classified as impaired based on a detailed assessment of certain larger loan relationships evaluated by a management committee referred to as the Watch List Committee. Specific loan relationships are identified for evaluation based on the related credit risk rating. For individual loans classified as impaired, an allowance is established when the collateral value less estimated selling costs, present value of discounted cash flows or observable market price of the impaired loan is lower than the carrying value of that loan. The scope of loans reviewed individually each quarter to determine if they are impaired include all commercial loan relationships greater than $200,000 and any residential mortgage or consumer loans of $400,000 or more for which there is at least one extension of credit graded Special Mention, Substandard or Doubtful. Loans that are individually reviewed, but which are determined to not be impaired, are combined with all remaining loans that are not reviewed on a specific basis, and such loans are included within larger pools of loans based on similar risk and loss characteristics for purposes of determining the general component of the allowance. All loans classified as troubled debt restructurings (TDR) and all commercial loan relationships less than $200,000 or other loan relationships less than $400,000 in the aggregate, but with an estimated loss of $100,000 or more, are individually evaluated for impairment. The general component covers pools of loans by loan class including commercial loans not considered individually impaired, as well as smaller balance homogeneous classes of loans, such as residential real estate, home equity lines of credit and other consumer loans. Accordingly, the Corporation generally does not separately identify individual consumer and residential loans for impairment disclosures, unless such a loan: (1) is subject to a restructuring agreement, (2) has an outstanding balance of $400,000 or more and a credit grade of Special Mention, Substandard or Doubtful, or (3) has an estimated loss of $100,000 or more. The pools of loans for each loan segment are evaluated for loss exposure based upon average historical net charge-off rates, adjusted for qualitative factors. The time period used in determining the average historical net charge-off rate for each loan class is based on management’s evaluation of an appropriate time period that captures an historical loss experience relevant to the current portfolio. Qualitative risk factors (described in the following paragraph) are evaluated for the impact on each of the three distinct segments (residential mortgage, commercial and consumer) within the loan portfolio. Each qualitative factor is assigned a value to reflect improving, stable or declining conditions based on management’s judgment using relevant information available at the time of the evaluation. Any adjustments to the factors are supported by a narrative documentation of changes in conditions accompanying the allowance for loan losses calculation. The qualitative factors used in the general component calculations are designed to address credit risk characteristics associated with each segment. The Corporation’s credit risk associated with all of the segments is significantly impacted by these factors, which include economic conditions within its market area, the Corporation’s lending policies, changes or trends in the portfolio, risk profile, competition, regulatory requirements and other factors. Purchased loans that did not show evidence of credit deterioration at the acquisition dates were initially recorded at fair value, including a discount for credit losses reflecting an estimate of the present value of credit losses based on market expectations. The general component of the allowance on purchased loans is evaluated separately from the rest of the portfolio. This evaluation includes consideration of the qualitative risk factors described above as well as the remaining purchased discount. Loans are classified as impaired when, based on current information and events, it is probable that the Corporation will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for commercial loans by the fair value of the collateral (if the loan is collateral dependent), by future cash flows discounted at the loan’s effective rate or by the loan’s observable market price. For commercial loans secured by real estate, estimated fair values are determined primarily through third-party appraisals. When a real estate secured loan becomes impaired, a decision is made regarding whether an updated certified appraisal of the real estate is necessary. This decision is based on various considerations, including the age of the most recent appraisal, the loan-to-value ratio based on the original appraisal and the condition of the property. Appraised values are discounted to arrive at the estimated selling price of the collateral, which is considered to be the estimated fair value. The discounts also include estimated costs to sell the property. For commercial and industrial loans secured by non-real estate collateral, such as accounts receivable, inventory and equipment, estimated fair values are determined based on the borrower’s financial statements, inventory reports, accounts receivable aging data or equipment appraisals or invoices. Indications of value from these sources are generally discounted based on the age of the financial information or the quality of the assets. Loans whose terms are modified are classified as troubled debt restructurings if the Corporation grants such borrowers concessions and it is deemed that those borrowers are experiencing financial difficulty. Concessions granted under a troubled debt restructuring generally involve reductions in required payments, an extension of a loan’s stated maturity date or a temporary reduction in interest rate. Loans classified as troubled debt restructurings are designated as impaired. Nonaccrual troubled debt restructurings may be restored to accrual status if the ultimate collectability of principal and interest payments under the modified terms is not in doubt, and there has been a period (generally, for at least six consecutive months) of satisfactory payment performance by the borrower either immediately before or after the restructuring. In March 2020, various regulatory agencies, including the Board of Governors of the Federal Reserve System and the Federal Deposit Insurance Corporation issued an interagency statement on loan modifications and reporting for financial institutions working with customers affected by COVID-19. The interagency statement was effective immediately and impacted accounting for loan modifications. The agencies confirmed with the staff of the FASB that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief, are not to be considered TDRs. Provisions of the CARES Act Section 4013 largely mirrored the provisions of the interagency statement, providing that modified loans were not to be considered TDRs if they were performing at December 31, 2019 and other considerations set forth in the interagency statements were met. Borrowers considered current are those that are less than 30 days past due on their contractual payments at the time a modification program is implemented or at December 31, 2019. Consistent with this guidance, the Corporation has not reported loans that were modified in response to COVID-19 as past due, nonaccrual or as TDRs.

Deferred tax assets are reduced, if necessary, by the amount of such benefits that are not expected to be realized based upon available evidence. Tax benefits from investments in limited partnerships that have qualified for federal low-income tax credits are recognized as a reduction in the provision for income tax over the term of the investment using the effective yield method. The Corporation includes income tax penalties in the provision for income tax. The Corporation has no accrued interest related to unrecognized tax benefits. STOCK COMPENSATION PLANS The fair value of each stock option is estimated on the date of grant using the Black-Scholes-Merton option valuation model. The fair value of restricted stock is based on the current market price on the date of grant. TREASURY STOCK – . OFF-BALANCE SHEET FINANCIAL INSTRUMENTS – CASH FLOWS – REVENUE RECOGNITION – Additional disclosures related to the Corporation’s largest sources of noninterest income within the consolidated statements of income from contracts with customers that are subject to Accounting Standards Codification (ASC) Topic 606 are as follows: Trust and financial management revenue – Trust revenue is recorded on a cash basis, which is not materially different from the accrual basis. The majority (approximately 84%, based on annual 2021 results) of trust revenue is earned and collected monthly, with the amount determined based on a percentage of the fair value of the trust assets under management. Wealth management fees are contractually agreed with each customer, and fee levels vary based mainly on the size of assets under management. The services provided under such a contract represent a single performance obligation under the Accounting Standards Updates (ASUs) because it embodies a series of distinct goods or services that are substantially the same and have the same pattern of transfer to the customer. None of the contracts with trust customers provide for incentive-based fees. In addition to wealth management fees, trust revenue includes fees for provision of services, including employee benefit plan administration, tax return preparation and estate planning and settlement. Fees for such services are billed based on contractual arrangements or established fee schedules and are typically billed upon completion of providing such services. The costs of acquiring trust customers are incremental and recognized within noninterest expense in the consolidated statements of income.

RECENT ACCOUNTING PRONOUNCEMENTS
RECENT ACCOUNTING PRONOUNCEMENTS	2. RECENT ACCOUNTING PRONOUNCEMENTS The Financial Accounting Standards Board (FASB) issues ASUs to the FASB ASC. This section provides a summary description of recent ASUs that have significant implications (elected or required) within the consolidated financial statements, or that management expects may have a significant impact on financial statements issued in the foreseeable future. Recently Issued But Not Yet Effective Accounting Pronouncements ASU 2016-13, Financial Instruments-Credit Losses (Topic 326), as modified by subsequent ASUs, changes accounting for credit losses on loans receivable and debt securities from an incurred loss methodology to an expected credit loss methodology. Among other things, ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Accordingly, ASU 2016-13 requires the use of forward-looking information to form credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, though the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, ASU 2016-13 amends the accounting for credit losses on debt securities and purchased financial assets with credit deterioration. The effect of implementing this ASU is recorded through a cumulative-effect adjustment to retained earnings. The Corporation has formed a cross functional management team and is working with an outside vendor assessing alternative loss estimation methodologies and the Corporation’s data and system needs to evaluate the impact that adoption of this standard will have on the Corporation’s financial condition and results of operations. In November 2019, the FASB approved a delay of the required implementation date of ASU 2016-13 for smaller reporting companies, including the Corporation, resulting in a required implementation date for the Corporation of January 1, 2023. ASU 2020-04, Reference Rate Reform (Topic 848) provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. The amendments in Update 2020-04 are elective and apply to all entities that have contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued. The guidance includes a general principle that permits an entity to consider contract modifications due to reference rate reform to be an event that does not require contract remeasurement at the modification date or reassessment of a previous accounting determination. Some specific optional expedients are as follows: ● Simplifies accounting for contract modifications, including modifications to loans receivable and debt, by prospectively adjusting the effective interest rate. ● Simplifies the assessment of hedge effectiveness and allows hedging relationships affected by reference rate reform to continue. The amendments in ASU 2020-04 are effective as of March 12, 2020 through December 31, 2022. The Corporation expects to apply the amendments prospectively for applicable loan and other contracts within the effective period of ASU 2020-04.

PER SHARE DATA
PER SHARE DATA	4. PER SHARE DATA Basic earnings per common share are calculated using the two-class method to determine income attributable to common shareholders. Unvested restricted stock awards that contain nonforfeitable rights to dividends are considered participating securities under the two-class method. Distributed dividends and an allocation of undistributed net income to participating securities reduce the amount of income attributable to common shareholders. Income attributable to common shareholders is then divided by weighted-average common shares outstanding for the period to determine basic earnings per common share. Diluted earnings per common share are calculated under the more dilutive of either the treasury method or the two-class method. Diluted earnings per common share is computed using weighted-average common shares outstanding, plus weighted-average common shares available from the exercise of all dilutive stock options, less the number of shares that could be repurchased with the proceeds of stock option exercises based on the average share price of the Corporation’s common stock during the period. ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands, Except Share and Per Share Data) ​ Years Ended ​ ​ December 31, ​ December 31, ​ 2021 2020 Basic ​ ​ ​ Net income ​ $ 30,554 ​ $ 19,222 Less: Dividends and undistributed earnings allocated to participating securities ​ (241) ​ (116) Net income attributable to common shares ​ $ 30,313 ​ $ 19,106 Basic weighted-average common shares outstanding ​ 15,765,639 ​ 14,743,386 Basic earnings per common share (a) ​ $ 1.92 ​ $ 1.30 Diluted ​ ​ Net income attributable to common shares ​ $ 30,313 ​ $ 19,106 Basic weighted-average common shares outstanding ​ 15,765,639 ​ 14,743,386 Dilutive effect of potential common stock arising from stock options ​ 6,316 ​ 3,662 Diluted weighted-average common shares outstanding ​ 15,771,955 ​ 14,747,048 Diluted earnings per common share (a) ​ $ 1.92 ​ $ 1.30 Weighted-average nonvested restricted shares outstanding ​ 125,539 ​ 89,718 (a) Basic and diluted earnings per share under the two-class method are determined on net income reported on the income statement less earnings allocated to nonvested restricted shares with nonforfeitable dividends (participating securities).

Cash flows from such investments are dependent upon the performance of the underlying mortgage loans and are generally influenced by the level of interest rates. In the table above, mortgage-backed securities and collateralized mortgage obligations are shown in one period. Investment securities carried at $241,428,000 at December 31, 2021 and $247,373,000 at December 31, 2020 were pledged as collateral for public deposits, trusts and certain other deposits, as provided by law, totaling $189,383,000 at December 31, 2021 and $201,176,000 at December 31, 2020. See Note 12 for information concerning securities pledged to secure borrowing arrangements and Note 21 for information related to securities pledged against interest rate swap obligations. Management evaluates securities for other-than-temporary impairment (“OTTI”) at least on a quarterly basis, and more frequently when economic or market conditions warrant such evaluation. Consideration is given to (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) whether the Corporation intends to sell the security or more likely than not will be required to sell the security before its anticipated recovery. A summary of information management considered in evaluating debt and equity securities for OTTI at December 31, 2021 and 2020 is provided below. Debt Securities At December 31, 2021 and 2020, management performed an assessment for possible OTTI of the Corporation’s debt securities on an issue-by-issue basis, relying on information obtained from various sources, including publicly available financial data, ratings by external agencies, brokers and other sources. The extent of individual analysis applied to each security depended on the size of the Corporation’s investment, as well as management’s perception of the credit risk associated with each security. Based on the results of the assessment, management believes impairment of these debt securities at December 31, 2021 and 2020 to be temporary. Equity Securities C&N Bank is a member of the Federal Home Loan Bank of Pittsburgh (FHLB-Pittsburgh), which is one of 11 regional Federal Home Loan Banks. As a member, C&N Bank is required to purchase and maintain stock in FHLB-Pittsburgh. There is no active market for FHLB-Pittsburgh stock, and it must ordinarily be redeemed by FHLB-Pittsburgh in order to be liquidated. C&N Bank’s investment in FHLB-Pittsburgh stock, included in Other Assets in the consolidated balance sheets, was $9,313,000 at December 31, 2021 and $9,720,000 at December 31, 2020. The Corporation evaluated its holding of FHLB-Pittsburgh stock for impairment and deemed the stock to not be impaired at December 31, 2021 and December 31, 2020. In making this determination, management concluded that recovery of total outstanding par value, which equals the carrying value, is expected. The decision was based on review of financial information that FHLB-Pittsburgh has made publicly available. The Corporation’s marketable equity security, with a carrying value of $971,000 at December 31, 2021 and $1,000,000 at December 31, 2020, consisted exclusively of one mutual fund. There was an unrealized loss of $29,000 on the mutual fund at December 31, 2021 and no unrealized gain/loss at December 31, 2020. The increase in the unrealized loss of $29,000 in 2021 and the decrease in the unrealized loss of $21,000 in 2020 are included in other noninterest income in the consolidated statements of income. There were no sales of equity securities in 2021 and 2020.

Loans outstanding at December 31, 2021 and December 31, 2020 are summarized by segment, and by classes within each segment, as follows: ​ Summary of Loans by Type (In Thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, December 31, ​ ​ 2021 ​ 2020 Commercial: ​ ​ Commercial loans secured by real estate ​ $ 569,840 ​ $ 531,810 Commercial and industrial ​ 159,073 ​ 159,577 Paycheck Protection Program - 1st Draw ​ ​ 1,356 ​ ​ 132,269 Paycheck Protection Program - 2nd Draw ​ ​ 25,508 ​ ​ 0 Political subdivisions ​ 81,301 ​ 53,221 Commercial construction and land ​ 60,579 ​ 42,874 Loans secured by farmland ​ 11,121 ​ 11,736 Multi-family (5 or more) residential ​ 50,089 ​ 55,811 Agricultural loans ​ 2,351 ​ 3,164 Other commercial loans ​ 17,153 ​ 17,289 Total commercial ​ 978,371 ​ 1,007,751 Residential mortgage: ​ ​ Residential mortgage loans - first liens ​ ​ 483,629 ​ ​ 532,947 Residential mortgage loans - junior liens ​ 23,314 ​ 27,311 Home equity lines of credit ​ 39,252 ​ 39,301 1-4 Family residential construction ​ 23,151 ​ 20,613 Total residential mortgage ​ 569,346 ​ 620,172 Consumer ​ 17,132 ​ 16,286 Total ​ 1,564,849 ​ 1,644,209 Less: allowance for loan losses ​ (13,537) ​ (11,385) Loans, net ​ $ 1,551,312 ​ $ 1,632,824 ​ In the table above, outstanding loan balances are presented net of deferred loan origination fees of $4,247,000 at December 31, 2021 and $6,286,000 at December 31, 2020. The Corporation grants loans to individuals as well as commercial and tax-exempt entities. Commercial, residential and personal loans are made to customers geographically concentrated in Northcentral Pennsylvania, the Southern tier of New York State, Southeastern Pennsylvania and Southcentral Pennsylvania. Although the Corporation has a diversified loan portfolio, a significant portion of its debtors’ ability to honor their contracts is dependent on the local economic conditions within the region On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was signed into law. The CARES Act is a $2 trillion stimulus package designed to provide relief to U.S. businesses and consumers struggling as a result of the pandemic. A provision in the CARES Act includes creation of the Paycheck Protection Program (“PPP”) through the Small Business Administration (“SBA”) and Treasury Department. Under the PPP, the Corporation, as an SBA-certified lender, provides SBA-guaranteed loans to small businesses to pay their employees, rent, mortgage interest, and utilities. PPP loans will be forgiven subject to clients’ providing documentation evidencing their compliant use of funds and otherwise complying with the terms of the program. Information related to PPP loans advanced pursuant to the CARES Act are labeled “1st Draw” within the tables. Section 4013 of the CARES Act provides that, from the period beginning March 1, 2020 until 60 days after the date on which the national emergency concerning the coronavirus (COVID-19) pandemic declared by the President of the United States under the National Emergencies Act terminates (the “applicable period”), the Corporation may elect to suspend U.S. GAAP for loan modifications related to the pandemic that would otherwise be categorized as troubled debt restructurings (TDRs) and suspend any determination of a loan modified as a result of the effects of the pandemic as being a TDR, including impairment for accounting purposes. The suspension is applicable for the term of the loan modification that occurs during the applicable period for a loan that was not more than 30 days past due as of December 31, 2019. The suspension is not applicable to any adverse impact on the credit of a borrower that is not related to the pandemic. In addition, the banking regulators and other financial regulators, on March 22, 2020 and revised April 7, 2020, issued a joint interagency statement titled the “Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus” that encourages financial institutions to work prudently with borrowers who are or may be unable to meet their contractual payment obligations due to the effects of the COVID-19 pandemic. Pursuant to the interagency statement, loan modifications that do not meet the conditions of Section 4013 of the CARES Act may still qualify as a modification that does not need to be accounted for as a TDR. Specifically, the agencies confirmed with the FASB staff that short-term modifications made in good faith in response to the pandemic to borrowers who were current prior to any relief are not TDRs under U.S. GAAP. This includes short-term (e.g. six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or delays in payment that are insignificant. Borrowers considered current are those that are less than 30 days past due on their contractual payments at the time a modification program is implemented. Appropriate allowances for loan and lease losses are expected to be maintained. With regard to loans not otherwise reportable as past due, financial institutions are not expected to designate loans with deferrals granted due to the pandemic as past due because of the deferral. The interagency statement also states that during short-term pandemic-related loan modifications, these loans generally should not be reported as nonaccrual. On December 27, 2020, the President of the United States signed into law the Consolidated Appropriations Act, 2021 (the “CAA”), which includes provisions that broadly address additional COVID-19 responses and relief. Among the additional relief measures included are certain extensions to elements of the CARES Act, including extension of temporary relief from troubled debt restructurings established under Section 4013 of the CARES Act to the earlier of a) January 1, 2022, or b) the date that is 60 days after the date on which the national COVID-19 emergency terminates. The CAA also includes additional funding for the PPP with additional eligibility requirements for borrowers with generally the same loan terms as provided under the CARES Act. Information related to PPP loans advanced pursuant to the CAA are labeled “2nd Draw” within the tables. The maximum term of PPP loans is five years. Most of the Corporation’s 1st Draw PPP loans have two-year terms, while 2nd Draw PPP loans have five-year terms and the Corporation will be repaid sooner to the extent the loans are forgiven. The interest rate on PPP loans is 1%, and the Corporation has received fees from the SBA ranging between 1% and 5% per loan, depending on the size of the loan. Fees on PPP loans, net of origination costs and a market rate adjustment on PPP loans acquired from Covenant, are recognized in interest income as a yield adjustment over the term of the loans. The Corporation began accepting and processing applications for loans under the PPP on April 3, 2020. Covenant also engaged in PPP lending starting in early April 2020. As of December 31, 2021, the recorded investment in 1st Draw PPP loans was $1,356,000 , including contractual principal balances of $1,410,000 , reduced by net deferred origination fees of $54,000 . The recorded investment in 2nd Draw PPP loans was $25,508,000 , including contractual principal balances of $26,356,000 reduced by net deferred origination fees of $848,000 . Accretion of fees received on PPP loans, net of amortization of the market rate adjustment on PPP loans acquired from Covenant, was $5,515,000 in 2021 and $1,901,000 in 2020. Interest and fees on PPP loans which are included in taxable interest and fees on loans in the consolidated statements of income totaled $6,530,000 in 2021 and $2,924,000 in 2020. To work with clients impacted by COVID-19, the Corporation offered short-term loan modifications on a case-by-case basis to borrowers who were current in their payments at the inception of the loan modification program. Prior to the merger, Covenant had a similar program in place, and these modified loans have been incorporated into the Corporation’s program. These efforts were designed to assist borrowers as they deal with the crisis and help the Corporation mitigate credit risk. For loans subject to the program, each borrower was required to resume making regularly scheduled loan payments at the end of the modification period and the deferred amounts have been moved to the end of the loan term. Consistent with Section 4013 of the CARES Act, the modified loans have not been reported as past due, nonaccrual or as TDRs at December 31, 2021 and 2020. Most of the initial modifications under the program became effective in 2020 and provided a deferral of interest or principal and interest for 90-to-180 days. At December 31, 2021, there were no loans in deferral status under the program. At December 31, 2020, there were 45 loans with a total recorded investment of $37,397,000, in deferral status under the program. As described in Note 3, effective July 1, 2020, the Corporation acquired loans pursuant to its acquisition of Covenant. In 2019, the Corporation acquired loans pursuant to the acquisition of Monument Bancorp, Inc. (“Monument”). Acquired loans were recorded at their initial fair value, with adjustments made to the gross amortized cost of loans based on movements in interest rates (market rate adjustment) and based on credit fair value adjustments on non-impaired loans and impaired loans. Subsequent to the acquisitions, the Corporation has recognized amortization and accretion of a portion of the market rate adjustments and credit adjustments on non-impaired (performing) loans, and a partial recovery of purchased credit impaired (PCI) loans. For the years ended December 31, 2021 and 2020, adjustments to the initial market rate and credit fair value adjustments of performing loans were recognized as follows: ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands) ​ Year Ended ​ ​ December 31, ​ December 31, ​ ​ 2021 ​ 2020 Market Rate Adjustment ​ ​ Adjustments to gross amortized cost of loans at beginning of period ​ $ 718 ​ $ (1,415) Market rate adjustment recorded in acquisition ​ ​ 0 ​ ​ 2,909 Amortization recognized in interest income ​ ​ (1,355) ​ ​ (776) Adjustments to gross amortized cost of loans at end of period ​ $ (637) ​ $ 718 Credit Adjustment on Non-impaired Loans ​ ​ ​ ​ ​ ​ Adjustments to gross amortized cost of loans at beginning of period ​ $ (5,979) ​ $ (1,216) Credit adjustment recorded in acquisition ​ ​ 0 ​ ​ (7,219) Accretion recognized in interest income ​ 2,644 ​ 2,456 Adjustments to gross amortized cost of loans at end of period ​ $ (3,335) ​ $ (5,979) ​ A summary of PCI loans held at December 31, 2021 and December 31, 2020 is as follows: ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands) ​ December 31, ​ December 31, ​ 2021 2020 Outstanding balance ​ $ 9,802 ​ $ 10,316 Carrying amount ​ 6,558 ​ 6,841 ​ Transactions within the allowance for loan losses, summarized by segment and class, were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, ​ ​ ​ ​ ​ ​ December 31, Year Ended December 31, 2021 ​ 2020 ​ ​ ​ ​ ​ ​ ​ Provision ​ 2021 (In Thousands) ​ Balance ​ Charge-offs ​ Recoveries ​ (Credit) ​ Balance Allowance for Loan Losses: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial: ​ ​ ​ ​ ​ Commercial loans secured by real estate ​ $ 3,051 ​ $ 0 ​ $ 2 ​ $ 1,352 ​ $ 4,405 Commercial and industrial ​ 2,245 ​ (1,464) ​ 20 ​ 1,922 ​ 2,723 Commercial construction and land ​ 454 ​ 0 ​ 0 ​ 183 ​ 637 Loans secured by farmland ​ 120 ​ 0 ​ 0 ​ (5) ​ 115 Multi-family (5 or more) residential ​ 236 ​ 0 ​ 0 ​ (21) ​ 215 Agricultural loans ​ 34 ​ 0 ​ 0 ​ (9) ​ 25 Other commercial loans ​ 168 ​ 0 ​ 0 ​ 5 ​ 173 Total commercial ​ 6,308 ​ (1,464) ​ 22 ​ 3,427 ​ 8,293 Residential mortgage: ​ ​ ​ ​ ​ Residential mortgage loans - first liens ​ ​ 3,524 ​ ​ (11) ​ ​ 4 ​ ​ 133 ​ ​ 3,650 Residential mortgage loans - junior liens ​ 349 ​ 0 ​ 0 ​ (165) ​ 184 Home equity lines of credit ​ 281 ​ 0 ​ 2 ​ 19 ​ 302 1-4 Family residential construction ​ 99 ​ 0 ​ 0 ​ 103 ​ 202 Total residential mortgage ​ 4,253 ​ (11) ​ 6 ​ 90 ​ 4,338 Consumer ​ 239 ​ (100) ​ 38 ​ 58 ​ 235 Unallocated ​ 585 ​ 0 ​ 0 ​ 86 ​ 671 Total Allowance for Loan Losses ​ $ 11,385 ​ $ (1,575) ​ $ 66 ​ $ 3,661 ​ $ 13,537 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, ​ ​ ​ ​ ​ ​ December 31, Year Ended December 31, 2020 ​ 2019 ​ ​ ​ ​ ​ ​ ​ Provision ​ 2020 (In Thousands) ​ Balance ​ Charge-offs ​ Recoveries ​ (Credit) ​ Balance Allowance for Loan Losses: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial: ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial loans secured by real estate ​ $ 1,921 ​ $ 0 ​ $ 0 ​ $ 1,130 ​ $ 3,051 Commercial and industrial ​ 1,391 ​ (2,236) ​ 16 ​ 3,074 ​ 2,245 Commercial construction and land ​ 966 ​ (107) ​ 0 ​ (405) ​ 454 Loans secured by farmland ​ 158 ​ 0 ​ 0 ​ (38) ​ 120 Multi-family (5 or more) residential ​ 156 ​ 0 ​ 0 ​ 80 ​ 236 Agricultural loans ​ 41 ​ 0 ​ 0 ​ (7) ​ 34 Other commercial loans ​ 155 ​ 0 ​ 0 ​ 13 ​ 168 Total commercial ​ 4,788 ​ (2,343) ​ 16 ​ 3,847 ​ 6,308 Residential mortgage: ​ ​ ​ ​ ​ Residential mortgage loans - first liens ​ ​ 3,405 ​ ​ 0 ​ ​ 39 ​ ​ 80 ​ ​ 3,524 Residential mortgage loans - junior liens ​ 384 ​ 0 ​ 1 ​ (36) ​ 349 Home equity lines of credit ​ 276 ​ 0 ​ 4 ​ 1 ​ 281 1-4 Family residential construction ​ 117 ​ 0 ​ 0 ​ (18) ​ 99 Total residential mortgage ​ 4,182 ​ 0 ​ 44 ​ 27 ​ 4,253 Consumer ​ 281 ​ (122) ​ 41 ​ 39 ​ 239 Unallocated ​ 585 ​ 0 ​ 0 ​ 0 ​ 585 Total Allowance for Loan Losses ​ $ 9,836 ​ $ (2,465) ​ $ 101 ​ $ 3,913 ​ $ 11,385 ​ For the year ended December 31, 2021, the provision for loan losses was $3,661,000, a decrease in expense of $252,000 as compared to 2020. In 2021, the provision included the impact of partial charge-offs totaling $1,463,000 on a commercial loan. At December 31, 2021, the recorded investment in this loan was $1,391,000. In total, the provision for 2021 included a net charge of $1,324,000 related to specific loans (net charge-offs of $1,509,000 offset by a net decrease in specific allowances on loans of $185,000), an increase of $2,251,000 in the collectively determined potion of the allowance and an $86,000 increase in the unallocated allowance. The increase in the collectively determined portion of the allowance reflected the impact of an increase in volume of commercial loans, excluding PPP loans. In 2020, the provision included a $2,219,000 charge-off on one commercial loan for which there was no recorded investment at December 31, 2021 and 2020. In determining the larger loan relationships for detailed assessment under the specific allowance component, the Corporation uses an internal risk rating system. Under the risk rating system, the Corporation classifies problem or potential problem loans as “Special Mention,” “Substandard,” or “Doubtful” on the basis of currently existing facts, conditions and values. Loans that do not currently expose the Corporation to sufficient risk to warrant classification as Substandard or Doubtful, but possess weaknesses that deserve management’s close attention, are deemed to be Special Mention. Substandard loans include those characterized by the distinct possibility that the Corporation will sustain some loss if the deficiencies are not corrected. Loans classified as Doubtful have all the weaknesses inherent in those classified as Substandard with the added characteristic that the weaknesses present make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. Risk ratings are updated any time that conditions or the situation warrants. Loans not classified are included in the “Pass” column in the table that follows. ​ The following tables summarize the aggregate credit quality classification of outstanding loans by risk rating as of December 31, 2021 and 2020: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ ​ ​ ​ ​ ​ ​ ​ Purchased ​ ​ (In Thousands) ​ ​ ​ ​ Special ​ ​ ​ ​ ​ ​ ​ Credit ​ ​ ​ ​ ​ Pass ​ Mention ​ Substandard ​ Doubtful ​ Impaired ​ Total Commercial: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial loans secured by real estate ​ $ 538,966 ​ $ 10,510 ​ $ 16,220 ​ $ 0 ​ $ 4,144 ​ $ 569,840 Commercial and Industrial ​ 142,775 ​ 10,841 ​ 4,694 ​ 0 ​ 763 ​ 159,073 Paycheck Protection Program -

The Senior Notes are unsecured and unsubordinated obligations of the Corporation only and are not obligations of, and are not guaranteed by, any subsidiary of the Corporation. The Senior Notes were recorded, net of debt issuance costs of $337,000, at an initial carrying amount of $14,663,000. Debt issuance costs are amortized over the term of the Senior Notes as an adjustment of the effective interest rate. Amortization of debt issuance costs associated with the Senior Notes totaling $38,000 in 2021 was included in interest expense in the consolidated statements of income.

EMPLOYEE AND POSTRETIREMENT BENEFIT PLANS
EMPLOYEE AND POSTRETIREMENT BENEFIT PLANS	13. EMPLOYEE AND POSTRETIREMENT BENEFIT PLANS DEFINED BENEFIT PLANS The Corporation sponsors a defined benefit health care plan that provides postretirement medical benefits and life insurance to employees who meet certain age and length of service requirements. Full-time employees no longer accrue service time toward the Corporation-subsidized portion of the medical benefits. The plan contains a cost-sharing feature which causes participants to pay for all future increases in costs related to benefit coverage. Accordingly, actuarial assumptions related to health care cost trend rates do not significantly affect the liability balance at December 31, 2021 and 2020 and are not expected to significantly affect the Corporation’s future expenses. The Corporation uses a December 31 measurement date for the postretirement plan. In an acquisition in 2007, the Corporation assumed the Citizens Trust Company Retirement Plan, a defined benefit pension plan. This plan covers certain employees who were employed by Citizens Trust Company on December 31, 2002, when the plan was amended to discontinue admittance of any future participant and to freeze benefit accruals. Information related to the Citizens Trust Company Retirement Plan has been included in the tables that follow. The Corporation uses a December 31 measurement date for this plan. The following table shows the funded status of the defined benefit plans: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Pension Postretirement (In Thousands) 2021 2020 2021 2020 CHANGE IN BENEFIT OBLIGATION: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Benefit obligation at beginning of year ​ $ 1,101 ​ $ 976 ​ $ 1,347 ​ $ 1,326 Service cost ​ 0 ​ 0 ​ 63 ​ 46 Interest cost ​ 20 ​ 23 ​ 33 ​ 39 Plan participants' contributions ​ 0 ​ 0 ​ 148 ​ 185 Actuarial loss (gain) ​ 12 ​ 108 ​ (65) ​ 11 Benefits paid ​ (5) ​ (6) ​ (229) ​ (260) Benefit obligation at end of year ​ $ 1,128 ​ $ 1,101 ​ $ 1,297 ​ $ 1,347 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ CHANGE IN PLAN ASSETS: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair value of plan assets at beginning of year ​ $ 1,062 ​ $ 971 ​ $ 0 ​ $ 0 Actual return on plan assets ​ 118 ​ 97 ​ 0 ​ 0 Employer contribution ​ 0 ​ 0 ​ 81 ​ 75 Plan participants' contributions ​ 0 ​ 0 ​ 148 ​ 185 Benefits paid ​ (5) ​ (6) ​ (229) ​ (260) Fair value of plan assets at end of year ​ $ 1,175 ​ $ 1,062 ​ $ 0 ​ $ 0 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Funded status at end of year ​ $ 47 ​ $ (39) ​ $ (1,297) ​ $ (1,347) ​ At December 31, 2021 and 2020, the following pension plan and postretirement plan asset and liability amounts were recognized in the consolidated balance sheets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Pension ​ Postretirement (In Thousands) 2021 2020 2021 2020 Other assets ​ $ 47 ​ $ 0 ​ $ 0 ​ $ 0 Accrued interest and other liabilities ​ ​ 0 ​ ​ 39 ​ ​ 1,297 ​ ​ 1,347 ​ At December 31, 2021 and 2020, the following items included in accumulated other comprehensive income had not been recognized as components of expense: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Pension ​ Postretirement (In Thousands) 2021 2020 2021 2020 Prior service cost ​ $ 0 ​ $ 0 ​ $ (186) ​ $ (217) Net actuarial loss (gain) ​ 182 ​ 277 ​ (271) ​ (211) Total ​ $ 182 ​ $ 277 ​ $ (457) ​ $ (428) ​ For the defined benefit pension plan, amortization of the net actuarial loss is expected to be $8,000 in 2022. For the postretirement plan, the estimated amount of prior service cost that will be amortized from accumulated other comprehensive income into net periodic benefit cost in 2022 is a reduction in expense of $31,000, and net actuarial gain of $9,000 is expected to be amortized in 2022. The accumulated benefit obligation for the defined benefit pension plan was $1,128,000 at December 31, 2021 and $1,101,000 at December 31, 2020. The components of net periodic benefit costs from defined benefit plans are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Pension ​ Postretirement (In Thousands) 2021 2020 2021 2020 Service cost ​ $ 0 ​ $ 0 ​ $ 63 ​ $ 46 Interest cost ​ 20 ​ 23 ​ 33 ​ 39 Expected return on plan assets ​ (30) ​ (27) ​ 0 ​ 0 Amortization of prior service cost ​ 0 ​ 0 ​ (31) ​ (31) Recognized net actuarial loss (gain) ​ 19 ​ 16 ​ (5) ​ (14) Total net periodic benefit cost ​ $ 9 ​ $ 12 ​ $ 60 ​ $ 40 ​ The weighted-average assumptions used to determine net periodic benefit cost are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Pension ​ Postretirement ​ 2021 2020 2021 2020 Discount rate 2.30 % 3.10 % 2.50 % 3.25 % Expected return on plan assets 4.81 % 4.99 % N/A N/A ​ Rate of compensation increase N/A N/A N/A N/A ​ ​ The weighted-average assumptions used to determine benefit obligations as of December 31, 2021 and 2020 are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Pension Postretirement ​ ​ 2021 2020 2021 2020 ​ Discount rate 2.60 % 2.30 % 3.00 % 2.50 % Rate of compensation increase N/A N/A N/A N/A ​ ​ Estimated future benefit payments, including only estimated employer contributions for the postretirement plan, which reflect expected future service, are as follows: ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands) Pension Postretirement 2022 ​ $ 542 ​ $ 84 2023 ​ 187 ​ 81 2024 ​ 8 ​ 83 2025 ​ 8 ​ 85 2026 ​ 14 ​ 95 2027-2031 ​ 360 ​ 428 ​ No estimated minimum contribution to the defined benefit pension plan is required in 2022, though the Corporation may make discretionary contributions. The expected return on pension plan assets is a significant assumption used in the calculation of net periodic benefit cost. This assumption reflects the average long-term rate of earnings expected on the funds invested or to be invested to provide for the benefits included in the projected benefit obligation. The fair values of pension plan assets at December 31, 2021 and 2020 are as follows: ​ ​ ​ ​ ​ ​ ​ ​ 2021 2020 Mutual funds invested principally in: ​ ​ ​ ​ Cash and cash equivalents 3 % 2 % Debt securities 38 % 36 % Equity securities 51 % 51 % Alternative funds 8 % 11 % Total 100 % 100 % ​ C&N Bank’s Wealth Management Department manages the investment of the pension plan assets. The Plan’s securities include mutual funds invested principally in debt securities, a diversified mix of large, mid- and small-capitalization U.S. stocks, foreign stocks and alternative asset classes such as real estate, commodities, and inflation-protected securities. The fair values of plan assets are determined based on Level 1 inputs (as described in Note 22). The Plan’s assets do not include any shares of the Corporation’s common stock. PROFIT SHARING AND DEFERRED COMPENSATION PLANS The Corporation has a profit sharing plan that incorporates the deferred salary savings provisions of Section 401(k) of the Internal Revenue Code. The Corporation’s matching contributions to the Plan depend upon the tax deferred contributions of employees. The Corporation’s total basic and matching contributions were $1,299,000 in 2021 and $1,050,000 in 2020. The Corporation has an Employee Stock Ownership Plan (ESOP). Contributions to the ESOP are discretionary, and the ESOP uses funds contributed to purchase Corporation stock for the accounts of ESOP participants. These purchases are made in the market (not directly from the Corporation), and employees are not permitted to purchase Corporation stock under the ESOP. The ESOP includes a diversification feature, which allows participants, upon reaching age 55 and 10 years of service (as defined), to sell up to 50% of their Corporation shares over a period of 6 years. As of December 31, 2021, and 2020, there were no shares allocated for repurchase by the ESOP. Dividends paid on shares held by the ESOP are charged to retained earnings. All Corporation shares owned through the ESOP are included in the calculation of weighted-average shares outstanding for purposes of calculating earnings per share – basic and diluted. The ESOP held 513,494 shares of Corporation stock at December 31, 2021 and 481,478 shares at December 31, 2020, all of which had been allocated to Plan participants. The Corporation’s contributions to the ESOP totaled $1,040,000 in 2021 and $912,000 in 2020. The Corporation has a nonqualified supplemental deferred compensation arrangement with its key officers. Charges to operating expense for officers’ supplemental deferred compensation were $314,000 in 2021 and $286,000 in 2020. In connection with the Covenant acquisition, the Corporation assumed an obligation to provide a supplemental retirement benefit to a former Covenant executive. Under the terms of the agreement, the executive or his heirs will receive monthly payments totaling $1 million over a 10-year period starting in October 2025. Effective July 1, 2020, the Corporation recorded a liability of $499,000 representing the present value of the obligation prior to the executive fully vesting in the benefit. In 2020, the Corporation recorded expense of $360,000, which is included in merger-related expenses in the consolidated statements of income, representing the impact of the executive fully vesting upon the change in control. In addition, the Corporation recorded expense of $13,000 in 2021 and $6,000 in 2020, which is included in pensions and other employee benefits in the consolidated statements of income, representing the effective interest cost on the obligation. The discount rate used to measure the liability is 1.5%. The balance of the liability, which is included in accrued interest and other liabilities in the consolidated balance sheets, is $878,000 at December 31, 2021 and $865,000 at December 31, 2020. The Corporation also has a nonqualified deferred compensation plan that allows selected officers the option to defer receipt of cash compensation, including base salary and any cash bonuses or other cash incentives. This nonqualified deferred compensation plan does not provide for Corporation contributions. STOCK-BASED COMPENSATION PLANS The Corporation has a Stock Incentive Plan for a selected group of senior officers. A total of 850,000 shares of common stock may be issued under the Stock Incentive Plan. Awards may be made under the Stock Incentive Plan in the form of qualified options (“Incentive Stock Options,” as defined in the Internal Revenue Code), nonqualified options, stock appreciation rights or restricted stock. Historically through December 31, 2021, all awards made under this Plan have consisted of Incentive Stock Options or restricted stock. Incentive Stock Options have an exercise price equal to the market value of the stock at the date of grant, vest after 6 months and expire after 10 years. There are 110,800 shares available for issuance under the Stock Incentive Plan as of December 31, 2021. Also, the Corporation has an Independent Directors Stock Incentive Plan. This plan permits awards of nonqualified stock options and/or restricted stock to non-employee directors. A total of 235,000 shares of common stock may be issued under the Independent Directors Stock Incentive Plan. The recipients’ rights to exercise stock options under this plan expire 10 years from the date of grant. The exercise prices of all stock options awarded under the Independent Directors Stock Incentive Plan are equal to market value as of the dates of grant. There are 96,309 shares available for issuance under the Independent Directors Stock Incentive Plan as of December 31, 2021. Total stock-based compensation expense is as follows: ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands) 2021 2020 Restricted stock ​ $ 1,214 ​ $ 1,050 Stock options ​ 0 ​ 0 Total ​ $ 1,214 ​ $ 1,050 ​ The following summarizes non-vested restricted stock activity for the year ended December 31, 2021: ​ ​ ​ ​ ​ ​ ​ ​ Weighted ​ ​ ​ ​ Average ​ ​ Number ​ Grant Date ​ of Shares Fair Value Outstanding, December 31, 2020 101,942 ​ $ 23.42 Granted 78,391 ​ $ 20.28 Vested (48,016) ​ $ 23.85 Forfeited (5,290) ​ $ 22.10 Outstanding, December 31, 2021 127,027 ​ $ 21.37 ​ Compensation cost related to restricted stock is recognized based on the market price of the stock at the grant date over the vesting period, adjusted for estimated and actual forfeitures.

OFF-BALANCE SHEET RISK
OFF-BALANCE SHEET RISK	16. OFF-BALANCE SHEET RISK The Corporation is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financial needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments involve, to varying degrees, elements of credit, interest rate or liquidity risk in excess of the amount recognized in the consolidated balance sheets. The contract amounts of these instruments express the extent of involvement the Corporation has in particular classes of financial instruments. The Corporation’s exposure to credit loss from nonperformance by the other party to the financial instruments for commitments to extend credit and standby letters of credit is represented by the contractual amount of these instruments. The Corporation uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. Financial instruments whose contract amounts represent credit risk at December 31, 2021 and 2020 are as follows: ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands) 2021 2020 Commitments to extend credit ​ $ 366,076 ​ $ 317,470 Standby letters of credit ​ 10,079 ​ 9,107 ​ Commitments to extend credit are legally binding agreements to lend to customers. Commitments generally have fixed expiration dates or other termination clauses and may require payment of fees. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future liquidity requirements. The Corporation evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Corporation, for extensions of credit is based on management’s credit assessment of the counterparty. Standby letters of credit are conditional commitments issued by the Corporation guaranteeing performance by a customer to a third party. Those guarantees are issued primarily to support public and private borrowing arrangements, including commercial paper, bond financing and similar transactions. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. Some of the standby letters of credit are collateralized by real estate or other assets, and others are unsecured. The extent to which proceeds from liquidation of collateral would be expected to cover the maximum potential amount of future payments related to standby letters of credit is not estimable. The Corporation has recorded no liability associated with standby letters of credit as of December 31, 2021 and 2020. Standby letters of credit as of December 31, 2021 expire as follows: ​ ​ ​ ​ ​ Year of Expiration (In Thousands) 2022 ​ $ 10,021 2023 ​ 13 2024 ​ ​ 20 2026 ​ ​ 25 Total ​ $ 10,079 ​

CONTINGENCIES
OPERATING LEASE COMMITMENTS AND CONTINGENCIES	17. OPERATING LEASE COMMITMENTS AND CONTINGENCIES Operating Lease Commitments Operating leases in which the Corporation is the lessee are recorded as operating lease Right of Use ("ROU") assets and operating lease liabilities, included in other assets and other liabilities, respectively, on the Consolidated Balance Sheets. The Corporation does not currently have any finance leases. Operating lease ROU assets represent the right to use an underlying asset during the lease term and operating lease liabilities represent the obligation to make lease payments arising from the lease. ROU assets and operating lease liabilities were recognized as of the date of adoption of ASU 2017-02 based on the present value of the remaining lease payments using a discount rate that represented the then Corporation’s incremental borrowing rate at the date of initial application. Operating lease expense, which is comprised of amortization of the ROU assets and the implicit interest accreted on the operating lease liability, is recognized on a straight line basis over the remaining lease term of the operating lease, and is recorded in office occupancy expense in the Consolidated Statements of Income. The leases relate to Bank branches with remaining lease terms of generally 1 The Corporation leases certain branch locations, office space and equipment. All leases are classified as operating leases. Leases with an initial term of 12 months or less are not recorded on the balance sheet and the related lease expense is recognized on a straight-line basis over the lease term. Certain leases include options to renew, with renewal terms that can extend the lease term from one As shown in the table below, at December 31, 2021, right-of-use assets of $3,751,000 were included in other assets ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, ​ December 31, (In Thousands) 2021 2020 Other assets ​ $ 3,751 ​ $ 3,446 Other liabilities ​ $ 3,751 ​ $ 3,446 ​ In 2021 and 2020, operating lease expenses are included in the following line item of the consolidated statements of income: ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands) 2021 2020 Net occupancy and equipment expense ​ $ 492 ​ $ 371 Total ​ $ 492 ​ $ 371 ​ A maturity analysis of the Corporation’s lease liabilities at December 31, 2021 is as follows: ​ (In Thousands) Lease Payments Due ​ ​ ​ ​ ​ 2022 $ 540 2023 ​ 528 2024 ​ 521 2025 ​ 501 2026 ​ 438 Thereafter ​ 1,524 Total lease payments ​ 4,052 Discount on cash flows ​ (301) Total lease liabilities ​ $ 3,751 ​ Litigation Matters ​ In the normal course of business, the Corporation is subject to pending and threatened litigation in which claims for monetary damages are asserted. In management’s opinion, the Corporation’s financial position and results of operations would not be materially affected by the outcome of these legal proceedings. ​ Trust Department Tax Reporting Contingency ​ The Corporation has incurred operational losses from compliance oversight related to trust department tax preparation and administration activities that occurred prior to 2020. In 2020, the Corporation made changes in internal controls and personnel responsible for trust department tax administration activities. Management implemented the changes in internal controls and personnel in an effort to mitigate and prevent the likelihood of new instances of non-compliance from trust department tax administration activities. Losses related to trust department tax compliance matters totaled $164,000 in 2021 and $571,000 in 2020. These losses are included in other noninterest expense in the consolidated statements of income. The balance of accrued interest and other liabilities in the consolidated balance sheets includes $465,000 at December 31, 2021 and $322,000 at December 31, 2020 related to specific tax compliance matters that have been identified; however, no estimate can be made of the amount of additional expenses that may be incurred related to these matters.

REGULATORY MATTERS
REGULATORY MATTERS	18. REGULATORY MATTERS In August 2018, the Federal Reserve Board issued an interim final rule that expanded applicability of the Board’s small bank holding company policy statement. The interim final rule raised the policy statement’s asset threshold from $1 billion to $3 billion in total consolidated assets for a bank holding company or savings and loan holding company that: (1) is not engaged in significant nonbanking activities; (2) does not conduct significant off-balance sheet activities; and (3) does not have a material amount of debt or equity securities, other than trust-preferred securities, outstanding. The interim final rule provides that, if warranted for supervisory purposes, the Federal Reserve may exclude a company from the threshold increase. Management believes the Corporation meets the conditions of the Federal Reserve’s small bank holding company policy statement and is therefore excluded from consolidated capital requirements at December 31, 2021; however, C&N Bank remains subject to regulatory capital requirements administered by the federal banking agencies. Details concerning capital ratios at December 31, 2021 and December 31, 2020 are presented below. Management believes, as of December 31, 2021, that C&N Bank meets all capital adequacy requirements to which it is subject and maintains a capital conservation buffer (described in more detail below) that allows the Bank to avoid limitations on capital distributions, including dividend payments and certain discretionary bonus payments to executive officers. Further, as reflected in the table below, the Corporation’s and C&N Bank’s capital ratios at December 31, 2021 and December 31, 2020 exceed the Corporation’s Board policy threshold levels. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Minimum To Be Well ​ ​ ​ ​ ​ ​ ​ Minimum ​ Minimum To Maintain ​ Capitalized Under ​ Minimum To Meet ​ ​ ​ ​ ​ Capital ​ Capital Conservation ​ Prompt Corrective ​ the Corporation's ​ ​ Actual ​ Requirement Buffer at Reporting Date ​ Action Provisions ​ Policy Thresholds ​ (Dollars In Thousands) ​ Amount Ratio Amount Ratio Amount Ratio Amount Ratio Amount Ratio ​ December 31, 2021: ​ ​ ​ Total capital to risk-weighted assets: ​ ​ ​ Consolidated ​ $ 287,614 18.21 % N/A N/A N/A N/A N/A N/A ​ $ 165,846 ³ 10.5 % C&N Bank ​ 252,606 16.04 % 126,012 ³ 8 % 165,390 ³ 10.5 % 157,514 ³ 10 % 165,390 ³ 10.5 % Tier 1 capital to risk-weighted assets: ​ ​ ​ ​ ​ ​ ​ ​ Consolidated ​ 240,433 15.22 % N/A N/A N/A N/A N/A N/A ​ 134,256 ³ 8.5 % C&N Bank ​ 238,434 15.14 % 94,509 ³ 6 % 133,887 ³ 8.5 % 126,012 ³ 8 % 133,887 ³ 8.5 % Common equity tier 1 capital to risk-weighted assets: ​ ​ ​ Consolidated ​ 240,433 15.22 % N/A N/A N/A N/A N/A N/A ​ 110,564 ³ 7 % C&N Bank ​ 238,434 15.14 % 70,881 ³ 4.5 % 110,260 ³ 7.0 % 102,384 ³ 6.5 % 110,260 ³ 7 % Tier 1 capital to average assets: ​ ​ ​ ​ ​ ​ ​ Consolidated ​ 240,433 10.53 % N/A N/A N/A N/A N/A N/A ​ 182,683 ³ 8 % C&N Bank ​ 238,434 10.52 % 90,688 ³ 4 % N/A N/A 113,360 ³ 5 % 181,376 ³ 8 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020: ​ ​ ​ Total capital to risk-weighted assets: ​ ​ ​ Consolidated ​ $ 260,015 17.49 % N/A N/A N/A N/A N/A N/A ​ $ 156,113 ³ 10.5 % C&N Bank ​ 236,943 15.98 % 118,602 ³ 8 % 155,665 ³ 10.5 % 148,252 ³ 10 % 155,665 ³ 10.5 % Tier 1 capital to risk-weighted assets: ​ ​ ​ Consolidated ​ 231,577 15.58 % N/A N/A N/A N/A N/A N/A ​ 126,377 ³ 8.5 % C&N Bank ​ 225,058 15.18 % 88,951 ³ 6 % 126,015 ³ 8.5 % 118,602 ³ 8 % 126,015 ³ 8.5 % Common equity tier 1 capital to risk-weighted assets: ​ ​ ​ Consolidated ​ 231,577 15.58 % N/A N/A N/A N/A N/A N/A ​ 104,075 ³ 7 % C&N Bank ​ 225,058 15.18 % 66,714 ³ 4.5 % 103,777 ³ 7.0 % 96,364 ³ 6.5 % 103,777 ³ 7 % Tier 1 capital to average assets: ​ ​ ​ Consolidated ​ 231,577 10.34 % N/A N/A N/A N/A N/A N/A ​ 179,206 ³ 8 % C&N Bank ​ 225,058 10.12 % 88,959 ³ 4 % N/A N/A 111,199 ³ 5 % 177,919 ³ 8 % ​ Federal regulatory authorities impose a capital rule providing that, to avoid limitations on capital distributions, including dividend payments and certain discretionary bonus payments to executive officers, a banking organization subject to the rule must hold a capital conservation buffer composed of common equity tier 1 capital above its minimum risk-based capital requirements. The buffer is measured relative to risk-weighted assets. At December 31, 2021, the minimum risk-based capital ratios, and the capital ratios including the capital conservation buffer, are as follows: ​ ​ ​ ​ ​ Minimum common equity tier 1 capital ratio 4.5 % Minimum common equity tier 1 capital ratio plus capital conservation buffer 7.0 % Minimum tier 1 capital ratio 6.0 % Minimum tier 1 capital ratio plus capital conservation buffer 8.5 % Minimum total capital ratio 8.0 % Minimum total capital ratio plus capital conservation buffer 10.5 % ​ A banking organization with a buffer greater than 2.5% over the minimum risk-based capital ratios would not be subject to additional limits on dividend payments or discretionary bonus payments; however, a banking organization with a buffer less than 2.5% would be subject to increasingly stringent limitations as the buffer approaches zero. Also, a banking organization is prohibited from making dividend payments or discretionary bonus payments if its eligible retained income is negative in that quarter and its capital conservation buffer ratio was less than 2.5% as of the beginning of that quarter. Eligible net income is defined as net income for the four calendar quarters preceding the current calendar quarter, net of any distributions and associated tax effects not already reflected in net income. A summary of payout restrictions based on the capital conservation buffer is as follows: ​ ​ ​ ​ ​ Capital Conservation Buffer Maximum Payout (as a % of risk-weighted assets) ​ (as a % of eligible retained income) Greater than 2.5% No payout limitation applies ≤2.5% and >1.875% ​ 60 % ≤1.875% and >1.25% ​ 40 % ≤1.25% and >0.625% ​ 20 % ≤0.625% ​ 0 % ​ At December 31, 2021, C&N Bank’s Capital Conservation Buffer, determined based on the minimum total capital ratio, was 8.04%. Banking regulators limit the amount of dividends that may be paid by C&N Bank to the Corporation. Retained earnings against which dividends may be paid without prior approval of the banking regulators amounted to approximately $88,252,000 at December 31, 2021, subject to the minimum capital ratio requirements noted above. Restrictions imposed by federal law prohibit the Corporation from borrowing from C&N Bank unless the loans are secured in specific amounts. Such secured loans to the Corporation are generally limited to 10% of C&N Bank’s tangible stockholder’s equity (excluding accumulated other comprehensive income) or $23,856,000 at December 31, 2021.

DERIVATIVE FINANCIAL INSTRUMENTS
DERIVATIVE FINANCIAL INSTRUMENTS	​ ​ 21. DERIVATIVE FINANCIAL INSTRUMENTS ​ The Corporation is a party to derivative financial instruments. These financial instruments consist of interest rate swap agreements which contain master netting and collateral provisions designed to protect the party at risk. Interest rate swaps with commercial loan banking customers were executed to facilitate their respective risk management strategies. Under the terms of these arrangements, the commercial banking customers effectively exchanged their floating interest rate exposures on loans into fixed interest rate exposures. Those interest rate swaps have been simultaneously economically hedged by offsetting interest rate swaps with a third party, such that the Corporation has effectively exchanged its fixed interest rate exposures for floating rate exposures. These derivatives are not designated as hedges and are not speculative. Rather, these derivatives result from a service provided to certain customers. As the interest rate swaps associated with this program do not meet the hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. The aggregate notional amount of interest rate swaps was $123,094,000 at December 31, 2021 and $135,740,000 at December 31, 2020. The Corporation originated no interest rate swaps in 2021 or 2020. There were no gross amounts of interest rate swap-related assets and liabilities not offset in the consolidated balance sheets at December 31, 2021. The net impact on the consolidated statements of income from interest rate swaps was a reduction in interest income on loans of $1,347,000 in 2021 and $698,000 in 2020. The table below presents the fair value of the Corporation’s derivative financial instruments as well as their classification on the consolidated balance sheets at December 31, 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands) At December 31, 2021 ​ At December 31, 2020 ​ Asset Derivatives ​ Liability Derivatives ​ Asset Derivatives ​ Liability Derivatives ​ Notional ​ Fair ​ Notional ​ Fair ​ Notional ​ Fair ​ Notional ​ Fair ​ Amount ​ Value (1) ​ Amount ​ Value (2) ​ Amount ​ Value (1) ​ Amount ​ Value (2) Interest rate swap agreements $ 61,547 ​ $ 3,104 ​ $ 61,547 ​ $ 3,104 ​ $ 67,870 ​ $ 6,566 ​ $ 67,870 ​ $ 6,566 ​ (1) Included in other assets in the consolidated balance sheets. (2) Included in accrued interest and other liabilities in the consolidated balance sheets. The Corporation’s agreement with its derivative counterparty provides that if the Corporation defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Corporation could also be declared in default on its derivative obligations. Further, if the Corporation were to fail to maintain its status as a well or adequately capitalized institution, then the counterparty could terminate the derivative positions and the Corporation would be required to settle its obligations under the agreements. Available-for-sale securities with a carrying value of $7,027,000 were pledged as collateral against the Corporation’s liability related to the interest rate swaps at December 31, 2021.

FAIR VALUE MEASUREMENTS AND FAIR VALUES OF FINANCIAL INSTRUMENTS
FAIR VALUE MEASUREMENTS AND FAIR VALUES OF FINANCIAL INSTRUMENTS	22. FAIR VALUE MEASUREMENTS AND FAIR VALUES OF FINANCIAL INSTRUMENTS The Corporation measures certain assets at fair value. Fair value is defined as the price that would be received to sell an asset in an orderly transaction between market participants at the measurement date. FASB ASC Topic 820, “Fair Value Measurements and Disclosures” establishes a framework for measuring fair value that includes a hierarchy used to classify the inputs used in measuring fair value. The hierarchy prioritizes the inputs used in determining valuations into three levels. The level in the fair value hierarchy within which the fair value measurement falls is determined based on the lowest level input that is significant to the fair value measurement. The levels of the fair value hierarchy are as follows: Level 1 – Fair value is based on unadjusted quoted prices in active markets that are accessible to the Corporation for identical assets. These generally provide the most reliable evidence and are used to measure fair value whenever available. Level 2 – Fair value is based on significant inputs, other than Level 1 inputs, that are observable either directly or indirectly for substantially the full term of the asset through corroboration with observable market data. Level 2 inputs include quoted market prices in active markets for similar assets, quoted market prices in markets that are not active for identical or similar assets and other observable inputs. Level 3 – Fair value is based on significant unobservable inputs. Examples of valuation methodologies that would result in Level 3 classification include option pricing models, discounted cash flows and other similar techniques. The Corporation monitors and evaluates available data relating to fair value measurements on an ongoing basis and recognizes transfers among the levels of the fair value hierarchy as of the date of an event or change in circumstances that affects the valuation method chosen. Examples of such changes may include the market for a particular asset becoming active or inactive, changes in the availability of quoted prices, or changes in the availability of other market data.

The following table shows quantitative information regarding significant techniques and inputs used at December 31, 2021 and 2020 for servicing rights assets measured using unobservable inputs (Level 3 methodologies) on a recurring basis: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value at ​ ​ ​ 12/31/2021 ​ Valuation ​ Unobservable ​ ​ ​ ​ Method or Value As of Asset ​ (In Thousands) ​ Technique ​ Input(s) ​ ​ ​ ​ 12/31/2021 Servicing rights ​ $ 2,329 Discounted cash flow Discount rate ​ 13.00 % Rate used through modeling period ​ ​ ​ ​ ​ Loan prepayment speeds ​ ​ 209.00 % Weighted-average PSA ​ ​ ​ ​ ​ Servicing fees ​ ​ 0.25 % of loan balances ​ ​ ​ ​ ​ ​ ​ ​ ​ 4.00 % of payments are late ​ ​ ​ ​ ​ ​ ​ ​ ​ 5.00 % late fees assessed ​ ​ ​ ​ ​ ​ ​ ​ ​ $ 1.94 ​ Miscellaneous fees per account per month ​ ​ ​ ​ ​ Servicing costs ​ $ 6.00 ​ Monthly servicing cost per account ​ ​ ​ ​ ​ ​ ​ ​ ​ $ 24.00 ​ Additional monthly servicing cost per loan on loans more than 30 days delinquent ​ ​ ​ ​ ​ ​ ​ ​ ​ 1.50 % of loans more than 30 days delinquent ​ ​ ​ ​ ​ ​ ​ ​ 3.00 % annual increase in servicing costs ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value at ​ ​ ​ 12/31/2020 ​ Valuation ​ Unobservable ​ ​ ​ ​ Method or Value As of Asset ​ (In Thousands) ​ Technique ​ Input(s) ​ ​ ​ ​ 12/31/2020 Servicing rights ​ $ 1,689 Discounted cash flow Discount rate ​ 13.00 % Rate used through modeling period ​ ​ ​ ​ ​ Loan prepayment speeds ​ ​ 277.00 % Weighted-average PSA ​ ​ ​ ​ ​ Servicing fees ​ ​ 0.25 % of loan balances ​ ​ ​ ​ ​ ​ ​ ​ ​ 4.00 % of payments are late ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 5.00 % late fees assessed ​ ​ ​ ​ ​ ​ ​ ​ ​ $ 1.94 Miscellaneous fees per account per month ​ ​ ​ ​ ​ ​ Servicing costs ​ $ 6.00 ​ Monthly servicing cost per account ​ ​ ​ ​ ​ ​ ​ ​ ​ $ 24.00 ​ Additional monthly servicing cost per loan on loans more than 30 days delinquent ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 1.50 % of loans more than 30 days delinquent ​ ​ ​ ​ ​ ​ ​ ​ 3.00 % annual increase in servicing costs ​ ​ The fair value of servicing rights is affected by expected future interest rates. Increases (decreases) in future expected interest rates tend to increase (decrease) the fair value of the Corporation’s servicing rights because of changes in expected prepayment behavior by the borrowers on the underlying loans.

Foreclosed assets held for sale consist of real estate acquired by foreclosure. For impaired commercial loans secured by real estate and foreclosed assets held for sale, estimated fair values are determined primarily using values from third-party appraisals. Appraised values are discounted to arrive at the estimated selling price of the collateral, which is considered to be the estimated fair value. The discounts also include estimated costs to sell the property. At December 31, 2021 and 2020, quantitative information regarding significant techniques and inputs used for nonrecurring fair value measurements using unobservable inputs (Level 3 methodologies) are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (Dollars In Thousands) ​ ​ ​ ​ Weighted ​ ​ ​ ​ ​ Valuation ​ ​ ​ ​ ​ Average ​ ​ Balance at ​ Allowance at ​ Fair Value at ​ Valuation ​ Unobservable ​ Discount at Asset ​ 12/31/2021 ​ 12/31/2021 ​ 12/31/2021 ​ Technique ​ Inputs ​ 12/31/2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Impaired loans: ​ ​ ​ ​ Commercial: ​ ​ ​ ​ ​ ​ ​ Commercial loans secured by real estate ​ $ 6,468 ​ $ 668 ​ $ 5,800 Sales comparison Discount to appraised value 27 % Commercial and industrial ​ ​ 72 ​ ​ 72 ​ ​ 0 ​ Liquidation of assets Discount to appraised value 100 % Total impaired loans ​ $ 6,540 ​ $ 740 ​ $ 5,800 ​ Foreclosed assets held for sale - real estate: ​ ​ ​ ​ Commercial real estate ​ $ 428 ​ $ 0 ​ $ 428 Sales comparison Discount to appraised value 50 % Residential (1-4 family) ​ ​ 256 ​ ​ 0 ​ ​ 256 Sales comparison Discount to appraised value 53 % Total foreclosed assets held for sale ​ $ 684 ​ $ 0 ​ $ 684 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (Dollars In Thousands) ​ ​ ​ ​ Weighted ​ ​ ​ ​ Valuation ​ ​ ​ ​ ​ Average ​ ​ Balance at ​ Allowance at ​ Fair Value at ​ Valuation ​ Unobservable ​ Discount at Asset ​ 12/31/2020 ​ 12/31/2020 ​ 12/31/2020 ​ Technique ​ Inputs ​ 12/31/2020 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Impaired loans: ​ ​ ​ ​ Commercial: ​ ​ ​ ​ ​ ​ ​ Commercial loans secured by real estate ​ $ 6,501 ​ $ 691 ​ $ 5,810 Sales comparison Discount to appraised value 28 % Commercial and industrial ​ 72 ​ 72 ​ 0 Liquidation of assets Discount to appraised value 100 % Residential mortgage loans - first and junior liens ​ ​ 1,509 ​ ​ 162 ​ ​ 1,347 Sales comparison Discount to appraised value 31 % Total impaired loans ​ $ 8,082 ​ $ 925 ​ $ 7,157 ​ Foreclosed assets held for sale - real estate: ​ ​ ​ ​ Commercial real estate ​ $ 1,258 ​ $ 0 ​ $ 1,258 Sales comparison Discount to appraised value 44 % Residential (1-4 family) ​ ​ 80 ​ ​ 0 ​ ​ 80 Sales comparison Discount to appraised value 36 % Total foreclosed assets held for sale ​ $ 1,338 ​ $ 0 ​ $ 1,338 ​ ​ Certain of the Corporation’s financial instruments are not measured at fair value in the consolidated financial statements. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. Certain financial instruments and all nonfinancial instruments are excluded from disclosure requirements. Therefore, the aggregate fair value amounts presented may not represent the underlying fair value of the Corporation.

NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
BASIS OF CONSOLIDATION	BASIS OF CONSOLIDATION –
NATURE OF OPERATIONS	NATURE OF OPERATIONS – The Corporation provides banking and related services to individual and corporate customers. Lending products include commercial, mortgage and consumer loans, as well as specialized instruments such as commercial letters-of-credit. Deposit products include various types of checking accounts, passbook and statement savings, money market accounts, interest checking accounts, Individual Retirement Accounts and certificates of deposit. The Corporation provides wealth management services through its trust department, including administration of trusts and estates, retirement plans, and other employee benefit plans, and investment management services. The Corporation offers a variety of personal and commercial insurance products through C&N Financial Services Corporation. C&N Financial Services Corporation also offers mutual funds, annuities, educational savings accounts and other investment products through registered agents. Management has determined that the Corporation has one reportable segment, “Community Banking.” All of the Corporation’s activities are interrelated, and each activity is dependent and assessed based on how each of the activities of the Corporation supports the others. The Corporation is subject to competition from other financial institutions. It is also subject to regulation by certain federal and state agencies and undergoes periodic examination by those regulatory authorities. As a consequence, the Corporation’s business is particularly susceptible to being affected by future federal and state legislation and regulations.
USE OF ESTIMATES	USE OF ESTIMATES – Material estimates that are particularly susceptible to change include: (1) the allowance for loan losses and (2) fair values of available-for-sale debt securities based on estimates from independent valuation services or from brokers.
INVESTMENT SECURITIES	INVESTMENT SECURITIES – Available-for-sale debt securities – Other-than-temporary impairment – Marketable equity security Restricted equity securities
DERIVATIVES	DERIVATIVES –
LOANS HELD FOR SALE	LOANS HELD FOR SALE –
LOANS RECEIVABLE	LOANS RECEIVABLE – The loans receivable portfolio is segmented into residential mortgage, commercial and consumer loans. The residential mortgage segment includes the following classes: first and junior lien residential mortgages, home equity lines of credit and residential construction loans. The most significant classes of commercial loans are commercial loans secured by real estate, non-real estate secured commercial and industrial loans, loans to political subdivisions, commercial construction, multi-family residential and loans secured by farmland. Loans are placed on nonaccrual status for all classes of loans when, in the opinion of management, collection of interest is doubtful. Any unpaid interest previously accrued on those loans is reversed from income. Interest income is not recognized on specific impaired loans unless the likelihood of further loss is remote. Interest payments received on loans for which the risk of further loss is greater than remote are applied as a reduction of the loan principal balance. Interest income on other nonaccrual loans is recognized only to the extent of interest payments received. Generally, loans 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
PURCHASED LOANS	PURCHASED LOANS – 90 days The excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable yield and is recognized into interest income over the remaining life of the loan. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the nonaccretable yield. The nonaccretable yield represents estimated future credit losses expected to be incurred over the life of the loan. Subsequent decreases to the expected cash flows require us to evaluate the need for an allowance for credit losses. Subsequent improvements in expected cash flows result in the reversal of a corresponding amount of the nonaccretable yield which we then reclassify as accretable yield that is recognized into interest income over the remaining life of the loan using the interest method. Our evaluation of the amount of future cash flows that we expect to collect is performed in a similar manner as that used to determine our allowance for credit losses. Charge-offs of the principal amount on acquired loans would be first applied to the nonaccretable yield portion of the fair value adjustment.
ALLOWANCE FOR LOAN LOSSES	ALLOWANCE FOR LOAN LOSSES – 120 days The allowance for loan losses is maintained at a level considered adequate to provide for losses that can be reasonably anticipated. Management performs a quarterly evaluation of the adequacy of the allowance. The allowance is based on the Corporation’s past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral, composition of the loan portfolio, current economic conditions and other relevant factors. This evaluation is inherently subjective as it requires material estimates that may be susceptible to significant revision as more information becomes available. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Corporation’s allowance for loan losses. Such agencies may require the Corporation to recognize adjustments to the allowance based on their judgments of information available to them at the time of their examination. In the process of evaluating the loan portfolio, management also considers the Corporation’s exposure to losses from unfunded loan commitments. As of December 31, 2021 and 2020, management determined that no allowance for credit losses related to unfunded loan commitments was required. The allowance consists primarily of two major components – (1) a specific component based on a detailed assessment of certain larger loan relationships, mainly commercial purpose, determined on a loan-by-loan basis; and (2) a general component for the remainder of the portfolio based on a collective evaluation of pools of loans with similar risk characteristics. The general component is assigned to each pool of loans based on both historical net charge-off experience, and an evaluation of certain qualitative factors. An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the above methodologies for estimating specific and general losses in the portfolio. The specific component relates to loans that are classified as impaired based on a detailed assessment of certain larger loan relationships evaluated by a management committee referred to as the Watch List Committee. Specific loan relationships are identified for evaluation based on the related credit risk rating. For individual loans classified as impaired, an allowance is established when the collateral value less estimated selling costs, present value of discounted cash flows or observable market price of the impaired loan is lower than the carrying value of that loan. The scope of loans reviewed individually each quarter to determine if they are impaired include all commercial loan relationships greater than $200,000 and any residential mortgage or consumer loans of $400,000 or more for which there is at least one extension of credit graded Special Mention, Substandard or Doubtful. Loans that are individually reviewed, but which are determined to not be impaired, are combined with all remaining loans that are not reviewed on a specific basis, and such loans are included within larger pools of loans based on similar risk and loss characteristics for purposes of determining the general component of the allowance. All loans classified as troubled debt restructurings (TDR) and all commercial loan relationships less than $200,000 or other loan relationships less than $400,000 in the aggregate, but with an estimated loss of $100,000 or more, are individually evaluated for impairment. The general component covers pools of loans by loan class including commercial loans not considered individually impaired, as well as smaller balance homogeneous classes of loans, such as residential real estate, home equity lines of credit and other consumer loans. Accordingly, the Corporation generally does not separately identify individual consumer and residential loans for impairment disclosures, unless such a loan: (1) is subject to a restructuring agreement, (2) has an outstanding balance of $400,000 or more and a credit grade of Special Mention, Substandard or Doubtful, or (3) has an estimated loss of $100,000 or more. The pools of loans for each loan segment are evaluated for loss exposure based upon average historical net charge-off rates, adjusted for qualitative factors. The time period used in determining the average historical net charge-off rate for each loan class is based on management’s evaluation of an appropriate time period that captures an historical loss experience relevant to the current portfolio. Qualitative risk factors (described in the following paragraph) are evaluated for the impact on each of the three distinct segments (residential mortgage, commercial and consumer) within the loan portfolio. Each qualitative factor is assigned a value to reflect improving, stable or declining conditions based on management’s judgment using relevant information available at the time of the evaluation. Any adjustments to the factors are supported by a narrative documentation of changes in conditions accompanying the allowance for loan losses calculation. The qualitative factors used in the general component calculations are designed to address credit risk characteristics associated with each segment. The Corporation’s credit risk associated with all of the segments is significantly impacted by these factors, which include economic conditions within its market area, the Corporation’s lending policies, changes or trends in the portfolio, risk profile, competition, regulatory requirements and other factors. Purchased loans that did not show evidence of credit deterioration at the acquisition dates were initially recorded at fair value, including a discount for credit losses reflecting an estimate of the present value of credit losses based on market expectations. The general component of the allowance on purchased loans is evaluated separately from the rest of the portfolio. This evaluation includes consideration of the qualitative risk factors described above as well as the remaining purchased discount. Loans are classified as impaired when, based on current information and events, it is probable that the Corporation will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for commercial loans by the fair value of the collateral (if the loan is collateral dependent), by future cash flows discounted at the loan’s effective rate or by the loan’s observable market price. For commercial loans secured by real estate, estimated fair values are determined primarily through third-party appraisals. When a real estate secured loan becomes impaired, a decision is made regarding whether an updated certified appraisal of the real estate is necessary. This decision is based on various considerations, including the age of the most recent appraisal, the loan-to-value ratio based on the original appraisal and the condition of the property. Appraised values are discounted to arrive at the estimated selling price of the collateral, which is considered to be the estimated fair value. The discounts also include estimated costs to sell the property. For commercial and industrial loans secured by non-real estate collateral, such as accounts receivable, inventory and equipment, estimated fair values are determined based on the borrower’s financial statements, inventory reports, accounts receivable aging data or equipment appraisals or invoices. Indications of value from these sources are generally discounted based on the age of the financial information or the quality of the assets. Loans whose terms are modified are classified as troubled debt restructurings if the Corporation grants such borrowers concessions and it is deemed that those borrowers are experiencing financial difficulty. Concessions granted under a troubled debt restructuring generally involve reductions in required payments, an extension of a loan’s stated maturity date or a temporary reduction in interest rate. Loans classified as troubled debt restructurings are designated as impaired. Nonaccrual troubled debt restructurings may be restored to accrual status if the ultimate collectability of principal and interest payments under the modified terms is not in doubt, and there has been a period (generally, for at least six consecutive months) of satisfactory payment performance by the borrower either immediately before or after the restructuring. In March 2020, various regulatory agencies, including the Board of Governors of the Federal Reserve System and the Federal Deposit Insurance Corporation issued an interagency statement on loan modifications and reporting for financial institutions working with customers affected by COVID-19. The interagency statement was effective immediately and impacted accounting for loan modifications. The agencies confirmed with the staff of the FASB that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief, are not to be considered TDRs. Provisions of the CARES Act Section 4013 largely mirrored the provisions of the interagency statement, providing that modified loans were not to be considered TDRs if they were performing at December 31, 2019 and other considerations set forth in the interagency statements were met. Borrowers considered current are those that are less than 30 days past due on their contractual payments at the time a modification program is implemented or at December 31, 2019. Consistent with this guidance, the Corporation has not reported loans that were modified in response to COVID-19 as past due, nonaccrual or as TDRs.

REVENUE RECOGNITION	REVENUE RECOGNITION – Additional disclosures related to the Corporation’s largest sources of noninterest income within the consolidated statements of income from contracts with customers that are subject to Accounting Standards Codification (ASC) Topic 606 are as follows: Trust and financial management revenue – Trust revenue is recorded on a cash basis, which is not materially different from the accrual basis. The majority (approximately 84%, based on annual 2021 results) of trust revenue is earned and collected monthly, with the amount determined based on a percentage of the fair value of the trust assets under management. Wealth management fees are contractually agreed with each customer, and fee levels vary based mainly on the size of assets under management. The services provided under such a contract represent a single performance obligation under the Accounting Standards Updates (ASUs) because it embodies a series of distinct goods or services that are substantially the same and have the same pattern of transfer to the customer. None of the contracts with trust customers provide for incentive-based fees. In addition to wealth management fees, trust revenue includes fees for provision of services, including employee benefit plan administration, tax return preparation and estate planning and settlement. Fees for such services are billed based on contractual arrangements or established fee schedules and are typically billed upon completion of providing such services. The costs of acquiring trust customers are incremental and recognized within noninterest expense in the consolidated statements of income.
