BASIS OF INTERIM PRESENTATION AND STATUS OF RECENT ACCOUNTING PRONOUNCEMENTS
BASIS OF INTERIM PRESENTATION AND STATUS OF RECENT ACCOUNTING PRONOUNCEMENTS	1. BASIS OF INTERIM PRESENTATION AND STATUS OF RECENT ACCOUNTING PRONOUNCEMENTS The consolidated financial statements include the accounts of Citizens & Northern Corporation and its subsidiaries, Citizens & Northern Bank (“C&N Bank”), Bucktail Life Insurance Company and Citizens & Northern Investment Corporation (collectively, “Corporation”). The consolidated financial statements also include C&N Bank’s wholly-owned subsidiaries, C&N Financial Services Corporation and Northern Tier Holding LLC. C&N Bank is the sole member of Northern Tier Holding LLC. All material intercompany balances and transactions have been eliminated in consolidation. The consolidated financial information included herein, except the consolidated balance sheet dated December 31, 2020, is unaudited. Such information reflects all adjustments (consisting solely of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the financial position, results of operations, comprehensive income, cash flows and changes in stockholders’ equity for the interim periods; however, the information does not include all disclosures required by accounting principles generally accepted in the United States of America (“U.S. GAAP”) for a complete set of financial statements. Certain 2020 information has been reclassified for consistency with the 2021 presentation. Operating results reported for the nine-month period ended September 30, 2021 might not be indicative of the results for the year ending December 31, 2021. The Corporation evaluates subsequent events through the date of filing with the Securities and Exchange Commission. RECENT ACCOUNTING PRONOUNCEMENTS The Financial Accounting Standards Board (FASB) issues Accounting Standards Updates (ASUs) to the FASB Accounting Standards Codification (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 near 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 ASU 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 has formed a cross functional management team to evaluate and implement changes to contracts with rates indexed to LIBOR and 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	3. 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) ​ Three Months Ended Nine Months Ended ​ ​ September 30, ​ September 30, ​ September 30, ​ September 30, ​ 2021 2020 2021 2020 Basic ​ ​ ​ ​ ​ Net income ​ $ 7,399 ​ $ 2,848 ​ $ 23,246 ​ $ 12,452 Less: Dividends and undistributed earnings allocated to participating securities ​ (63) ​ (18) ​ (189) ​ (74) Net income attributable to common shares ​ $ 7,336 ​ $ 2,830 ​ $ 23,057 ​ $ 12,378 Basic weighted-average common shares outstanding ​ 15,703,932 ​ 15,778,391 ​ 15,806,897 ​ 14,388,797 Basic earnings per common share (a) ​ $ 0.47 ​ $ 0.18 ​ $ 1.46 ​ $ 0.86 Diluted ​ ​ ​ ​ Net income attributable to common shares ​ $ 7,336 ​ $ 2,830 ​ $ 23,057 ​ $ 12,378 Basic weighted-average common shares outstanding ​ 15,703,932 ​ 15,778,391 ​ 15,806,897 ​ 14,388,797 Dilutive effect of potential common stock arising from stock options ​ 6,413 ​ 1,330 ​ 6,232 ​ 4,632 Diluted weighted-average common shares outstanding ​ 15,710,345 ​ 15,779,721 ​ 15,813,129 ​ 14,393,429 Diluted earnings per common share (a) ​ $ 0.47 ​ $ 0.18 ​ $ 1.46 ​ $ 0.86 Weighted-average nonvested restricted shares outstanding ​ 133,053 ​ 102,629 ​ 129,456 ​ 85,611 (a) Basic and diluted earnings per share under the two-class method are determined on net income reported on the consolidated statements of income, less earnings allocated to non-vested 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 $254,062,000 at September 30, 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. See Note 9 for information concerning securities pledged to secure borrowing arrangements and Note 12 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 September 30, 2021 is provided below. Debt Securities At September 30, 2021 and December 31, 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 debt securities at September 30, 2021 and December 31, 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 $9,400,000 at September 30, 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 September 30, 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 has a marketable equity security included in other assets in the consolidated balance sheets with a carrying value of $981,000 at September 30, 2021 and $1,000,000 at December 31, 2020, consisting exclusively of one mutual fund. There was an unrealized loss on the mutual fund of $19,000 at September 30, 2021 and no unrealized gain or loss on the mutual fund at December 31, 2020. Changes in the unrealized gains or losses on this security are included in other noninterest income in the consolidated statements of income.

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 September 30, 2021, the recorded investment in 1st Draw PPP loans was $5,747,000, including contractual principal balances of $5,982,000, increased by a market rate adjustment on PPP loans acquired from Covenant of $2,000 and reduced by net deferred origination fees of $237,000. The recorded investment in 2nd Draw PPP loans was $56,981,000, including contractual principal balances of $59,190,000 reduced by net deferred origination fees of $2,208,000. Accretion of fees received on PPP loans, net of amortization of the market rate adjustment on PPP loans acquired from Covenant, was $1,409,000 in the three-month period ended September 30, 2021 and $467,000 in the three-month period ended September 30, 2020. Accretion of fees received on PPP loans, net of amortization of the market rate adjustment on PPP loans acquired from Covenant, was $3,975,000 in the nine-month period ended September 30, 2021 and $804,000 in the nine-month period ended September 30, 2020. ​ To work with clients impacted by COVID-19, the Corporation offers 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 have been 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 is required to resume making regularly scheduled loan payments at the end of the modification period and the deferred amounts will be 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 September 30, 2021. 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 September 30, 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 2, effective July 1, 2020, the Corporation acquired loans pursuant to its acquisition of Covenant, and effective April 1, 2019, the Corporation acquired loans pursuant to the acquisition of Monument Bancorp, Inc. (“Monument”). The 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 three-month and nine-month periods ended September 30, 2021 and 2020, adjustments to the initial market rate and credit fair value adjustments of performing loans were recognized as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended ​ ​ September 30, ​ September 30, ​ September 30, ​ September 30, ​ ​ 2021 ​ 2020 ​ 2021 ​ 2020 Market Rate Adjustment ​ ​ ​ ​ Adjustments to gross amortized cost of loans at beginning of period ​ $ (5) ​ $ (1,103) ​ $ 718 ​ $ (1,415) Market rate adjustment recorded in acquisition ​ ​ 0 ​ ​ 2,909 ​ ​ 0 ​ ​ 2,909 Amortization recognized in interest income ​ ​ (368) ​ ​ (452) ​ ​ (1,091) ​ ​ (140) Adjustments to gross amortized cost of loans at end of period ​ $ (373) ​ $ 1,354 ​ $ (373) ​ $ 1,354 Credit Adjustment on Non-impaired Loans ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Adjustments to gross amortized cost of loans at beginning of period ​ $ (4,502) ​ $ (878) ​ $ (5,979) ​ $ (1,216) Credit adjustment recorded in acquisition ​ ​ 0 ​ ​ (7,219) ​ ​ 0 ​ ​ (7,219) Accretion recognized in interest income ​ 666 ​ 970 ​ 2,143 ​ 1,308 Adjustments to gross amortized cost of loans at end of period ​ $ (3,836) ​ $ (7,127) ​ $ (3,836) ​ $ (7,127) ​ A summary of PCI loans held at September 30, 2021 and December 31, 2020 is as follows: ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands) ​ September 30, ​ December 31, ​ 2021 2020 Outstanding balance ​ $ 10,064 ​ $ 10,316 Carrying amount ​ 6,624 ​ 6,841 ​ The Corporation maintains an allowance for loan losses that represents management’s estimate of the losses inherent in the loan portfolio as of the balance sheet date and recorded as a reduction of the investment in loans. 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 the process of evaluating the loan portfolio, management also considers the Corporation’s exposure to losses from unfunded loan commitments. As of September 30, 2021 and December 31, 2020, management determined that no allowance for credit losses related to unfunded loan commitments was required. Transactions within the allowance for loan losses, summarized by segment and class, for the three-month and nine-month periods ended September 30, 2021 and 2020 were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended September 30, 2021 ​ June 30, 2021 ​ ​ ​ September 30, 2021 (In Thousands) Balance Charge-offs Recoveries Provision (Credit) Balance Allowance for Loan Losses: ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial: ​ ​ ​ ​ ​ Commercial loans secured by real estate ​ $ 3,452 ​ $ 0 ​ $ 0 ​ $ 368 ​ $ 3,820 Commercial and industrial ​ 2,781 ​ (1,194) ​ 6 ​ 947 ​ 2,540 Commercial construction and land ​ 452 ​ 0 ​ 0 ​ 107 ​ 559 Loans secured by farmland ​ 113 ​ 0 ​ 0 ​ (1) ​ 112 Multi-family (5 or more) residential ​ 150 ​ 0 ​ 0 ​ 46 ​ 196 Agricultural loans ​ 25 ​ 0 ​ 0 ​ 8 ​ 33 Other commercial loans ​ 145 ​ 0 ​ 0 ​ 28 ​ 173 Total commercial ​ 7,118 ​ (1,194) ​ 6 ​ 1,503 ​ 7,433 Residential mortgage: ​ ​ ​ ​ ​ ​ ​ ​ ​ Residential mortgage loans - first liens ​ ​ 3,536 ​ ​ 0 ​ ​ 1 ​ ​ 29 ​ ​ 3,566 Residential mortgage loans - junior liens ​ 327 ​ 0 ​ 0 ​ (6) ​ 321 Home equity lines of credit ​ 294 ​ 0 ​ 0 ​ (11) ​ 283 1-4 Family residential construction ​ 198 ​ 0 ​ 0 ​ (9) ​ 189 Total residential mortgage ​ 4,355 ​ 0 ​ 1 ​ 3 ​ ​ 4,359 Consumer ​ 231 ​ (26) ​ 8 ​ 24 ​ 237 Unallocated ​ 671 ​ 0 ​ 0 ​ 0 ​ 671 Total Allowance for Loan Losses ​ $ 12,375 ​ $ (1,220) ​ $ 15 ​ $ 1,530 ​ $ 12,700 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended September 30, 2020 ​ June 30, 2020 ​ ​ ​ September 30, 2020 (In Thousands) Balance Charge-offs Recoveries Provision (Credit) Balance Allowance for Loan Losses: ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial: ​ ​ ​ ​ ​ Commercial loans secured by real estate ​ $ 2,426 ​ $ 0 ​ $ 0 ​ $ (40) ​ $ 2,386 Commercial and industrial ​ 2,496 ​ (2,219) ​ 0 ​ 1,974 ​ 2,251 Commercial construction and land ​ 420 ​ 0 ​ 0 ​ 20 ​ 440 Loans secured by farmland ​ 146 ​ 0 ​ 0 ​ (25) ​ 121 Multi-family (5 or more) residential ​ 163 ​ 0 ​ 0 ​ 64 ​ 227 Agricultural loans ​ 40 ​ 0 ​ 0 ​ (3) ​ 37 Other commercial loans ​ 167 ​ 0 ​ 0 ​ 0 ​ 167 Total commercial ​ 5,858 ​ (2,219) ​ 0 ​ 1,990 ​ 5,629 Residential mortgage: ​ ​ ​ ​ ​ ​ ​ ​ ​ Residential mortgage loans - first liens ​ ​ 3,531 ​ ​ 0 ​ ​ 26 ​ ​ (92) ​ ​ 3,465 Residential mortgage loans - junior liens ​ 365 ​ 0 ​ 0 ​ (7) ​ 358 Home equity lines of credit ​ 287 ​ 0 ​ 1 ​ 1 ​ 289 1-4 Family residential construction ​ 137 ​ 0 ​ 0 ​ 32 ​ 169 Total residential mortgage ​ 4,320 ​ 0 ​ 27 ​ (66) ​ 4,281 Consumer ​ 263 ​ (30) ​ 8 ​ 17 ​ 258 Unallocated ​ 585 ​ 0 ​ 0 ​ 0 ​ 585 Total Allowance for Loan Losses ​ $ 11,026 ​ $ (2,249) ​ $ 35 ​ $ 1,941 ​ $ 10,753 ​ For the three months ended September 30, 2021, the provision for loan losses was $1,530,000, a decrease in expense of $411,000 as compared to $1,941,000 for the three months ended September 30, 2020. The third quarter 2021 provision included a net charge of $611,000 related to specific loans (net charge-offs of $1,205,000 offset by a net decrease in specific allowances on loans of $594,000), and an increase of $919,000 in the collectively determined portion of the allowance. In the third quarter 2021, the Corporation recorded a partial charge-off of $1,194,000 on a commercial loan with an outstanding balance of $3,496,000 at the time of the charge-off. The partial charge-off amount exceeded the specific allowance of $583,000 that had been established on this loan at June 30, 2021. The provision for loan losses in the third quarter 2020 included the net impact of a charge-off of $2,219,000 on a commercial loan of $3,500,000 for which the previously-established allowance had been $1,193,000. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, ​ ​ ​ ​ ​ ​ September 30, Nine Months Ended September 30, 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 ​ $ 767 ​ $ 3,820 Commercial and industrial ​ 2,245 ​ (1,194) ​ 20 ​ 1,469 ​ 2,540 Commercial construction and land ​ 454 ​ 0 ​ 0 ​ 105 ​ 559 Loans secured by farmland ​ 120 ​ 0 ​ 0 ​ (8) ​ 112 Multi-family (5 or more) residential ​ 236 ​ 0 ​ 0 ​ (40) ​ 196 Agricultural loans ​ 34 ​ 0 ​ 0 ​ (1) ​ 33 Other commercial loans ​ 168 ​ 0 ​ 0 ​ 5 ​ 173 Total commercial ​ 6,308 ​ (1,194) ​ 22 ​ 2,297 ​ 7,433 Residential mortgage: ​ ​ ​ ​ ​ Residential mortgage loans - first liens ​ ​ 3,524 ​ ​ (11) ​ ​ 3 ​ ​ 50 ​ ​ 3,566 Residential mortgage loans - junior liens ​ 349 ​ 0 ​ 0 ​ (28) ​ 321 Home equity lines of credit ​ 281 ​ 0 ​ 2 ​ 0 ​ 283 1-4 Family residential construction ​ 99 ​ 0 ​ 0 ​ 90 ​ 189 Total residential mortgage ​ 4,253 ​ (11) ​ 5 ​ 112 ​ 4,359 Consumer ​ 239 ​ (73) ​ 33 ​ 38 ​ 237 Unallocated ​ 585 ​ 0 ​ 0 ​ 86 ​ 671 Total Allowance for Loan Losses ​ $ 11,385 ​ $ (1,278) ​ $ 60 ​ $ 2,533 ​ $ 12,700 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, ​ ​ ​ ​ ​ ​ September 30, Nine Months Ended September 30, 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 ​ $ 465 ​ $ 2,386 Commercial and industrial ​ 1,391 ​ (2,236) ​ 0 ​ 3,096 ​ 2,251 Commercial construction and land ​ 966 ​ (107) ​ 0 ​ (419) ​ 440 Loans secured by farmland ​ 158 ​ 0 ​ 0 ​ (37) ​ 121 Multi-family (5 or more) residential ​ 156 ​ 0 ​ 0 ​ 71 ​ 227 Agricultural loans ​ 41 ​ 0 ​ 0 ​ (4) ​ 37 Other commercial loans ​ 155 ​ 0 ​ 0 ​ 12 ​ 167 Total commercial ​ 4,788 ​ (2,343) ​ 0 ​ 3,184 ​ 5,629 Residential mortgage: ​ ​ ​ ​ ​ Residential mortgage loans - first liens ​ ​ 3,405 ​ ​ 0 ​ ​ 28 ​ ​ 32 ​ ​ 3,465 Residential mortgage loans - junior liens ​ 384 ​ 0 ​ 1 ​ (27) ​ 358 Home equity lines of credit ​ 276 ​ 0 ​ 3 ​ 10 ​ 289 1-4 Family residential construction ​ 117 ​ 0 ​ 0 ​ 52 ​ 169 Total residential mortgage ​ 4,182 ​ 0 ​ 32 ​ 67 ​ 4,281 Consumer ​ 281 ​ (100) ​ 35 ​ 42 ​ 258 Unallocated ​ 585 ​ 0 ​ 0 ​ 0 ​ 585 Total Allowance for Loan Losses ​ $ 9,836 ​ $ (2,443) ​ $ 67 ​ $ 3,293 ​ $ 10,753 ​ ​ For the nine months ended September 30, 2021, the provision for loan losses was $2,533,000, a decrease in expense of $760,000 as compared to $3,293,000 recorded for the nine months ended September 30, 2020. The provision for the nine months ended September 30, 2021, includes the impact of a charge-off of $1,194,000 on a commercial loan with an ouststanding balance of $3,496,000, as previously discussed. In comparison, the provision for loan losses in the first nine months of 2020 included the impact of the $2,219,000 charge-off of a commercial loan of $3,500,000. 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. 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. 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. 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 September 30, 2021 and December 31, 2020: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2021 ​ ​ ​ ​ ​ ​ ​ ​ Purchased ​ ​ (In Thousands) ​ ​ ​ ​ Special ​ ​ ​ ​ ​ ​ ​ Credit ​ ​ ​ ​ ​ Pass ​ Mention ​ Substandard ​ Doubtful ​ Impaired ​ Total Commercial: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial loans secured by real estate ​ $ 519,673 ​ $ 15,055 ​ $ 14,473 ​ $ 0 ​ $ 4,188 ​ $ 553,389 Commercial and Industrial ​ 136,858 ​ 8,578 ​ 6,028 ​ 0 ​ 780 ​ 152,244 Paycheck Protection Program -

There were no losses related to trust department tax compliance matters in the third quarter 2021. Losses related to a state tax reporting matter totaled $200,000 in the third quarter 2020. Losses related to trust department tax compliance matters totaled $107,000 in the nine months ended September 30, 2021, and $500,000 in the nine-month period ended September 30, 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 $429,000 at September 30, 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.

DERIVATIVE FINANCIAL INSTRUMENTS
DERIVATIVE FINANCIAL INSTRUMENTS	12. 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 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 $123,990,000 at September 30, 2021 and $135,740,000 at December 31, 2020. There were no interest rate swaps originated in the nine-month periods ended September 30, 2021 and 2020. There were no gross amounts of interest rate swap-related assets and liabilities not offset in the consolidated balance sheets at September 30, 2021. The net impact on the consolidated statements of income from interest rate swaps was a reduction in interest income on loans of $335,000 in the third quarter 2021 and $1,013,000 in the nine months ended September 30, 2021 as compared to a reduction in interest income on loans of $351,000 in the third quarter 2020 and the nine months ended September 30, 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 September 30, 2021 and December 31, 2020: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands) At September 30, 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 $ 61,995 ​ $ 3,902 ​ $ 61,995 ​ $ 3,902 ​ $ 67,870 ​ $ 6,566 ​ $ 67,870 ​ $ 6,566 ​ (1) Included in other assets 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 $7,069,000 were pledged as collateral against the Corporation’s liability related to the interest rate swaps at September 30, 2021.

FAIR VALUE MEASUREMENTS AND FAIR VALUES OF FINANCIAL INSTRUMENTS
FAIR VALUE MEASUREMENTS AND FAIR VALUES OF FINANCIAL INSTRUMENTS	13. FAIR VALUE MEASUREMENTS AND FAIR VALUES OF FINANCIAL INSTRUMENTS The Corporation measures certain assets and liabilities at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. FASB 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 or liabilities. 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 or liability through corroboration with observable market data. Level 2 inputs include quoted market prices in active markets for similar assets or liabilities, quoted market prices in markets that are not active for identical or similar assets or liabilities 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 or liability becoming active or inactive, changes in the availability of quoted prices, or changes in the availability of other market data. At September 30, 2021 and December 31, 2020, assets and liabilities measured at fair value and the valuation methods used are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2021 ​ Quoted ​ ​ ​ ​ ​ ​ ​ ​ Prices ​ Other ​ ​ ​ ​ ​ ​ ​ ​ in Active ​ Observable ​ Unobservable ​ Total ​ ​ Markets ​ Inputs ​ Inputs ​ Fair (In Thousands) ​ (Level 1) ​ (Level 2) ​ (Level 3) ​ Value Recurring fair value measurements, assets: ​ ​ ​ ​ AVAILABLE-FOR-SALE DEBT SECURITIES: ​ ​ ​ ​ Obligations of the U.S. Treasury ​ $ 0 ​ $ 25,068 ​ $ 0 ​ $ 25,068 Obligations of U.S. Government agencies ​ ​ 0 ​ ​ 24,312 ​ ​ 0 ​ ​ 24,312 Obligations of states and political subdivisions: ​ ​ ​ ​ ​ ​ Tax-exempt ​ 0 ​ 139,244 ​ 0 ​ 139,244 Taxable ​ 0 ​ 70,493 ​ 0 ​ 70,493 Mortgage-backed securities issued or guaranteed by U.S. Government agencies or sponsored agencies: ​ ​ ​ ​ Residential pass-through securities ​ 0 ​ 60,629 ​ 0 ​ 60,629 Residential collateralized mortgage obligations ​ 0 ​ 44,593 ​ 0 ​ 44,593 Commercial mortgage-backed securities ​ 0 ​ 73,518 ​ 0 ​ 73,518 Total available-for-sale debt securities ​ 0 ​ 437,857 ​ 0 ​ 437,857 Marketable equity security ​ 981 ​ 0 ​ 0 ​ 981 Servicing rights ​ 0 ​ 0 ​ 2,247 ​ 2,247 Interest rate swap agreements, assets ​ ​ 0 ​ ​ 3,902 ​ ​ 0 ​ ​ 3,902 Total recurring fair value measurements, assets ​ $ 981 ​ $ 441,759 ​ $ 2,247 ​ $ 444,987 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Recurring fair value measurements, liabilities, ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Interest rate swap agreements, liabilities ​ $ 0 ​ $ 3,902 ​ $ 0 ​ $ 3,902 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nonrecurring fair value measurements, assets: ​ ​ ​ ​ Impaired loans with a valuation allowance ​ $ 0 ​ $ 0 ​ $ 7,225 ​ $ 7,225 Valuation allowance ​ 0 ​ 0 ​ (883) ​ (883) Impaired loans, net ​ 0 ​ 0 ​ 6,342 ​ 6,342 Foreclosed assets held for sale ​ 0 ​ 0 ​ 1,374 ​ 1,374 Total nonrecurring fair value measurements, assets ​ $ 0 ​ $ 0 ​ $ 7,716 ​ $ 7,716 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 ​ Quoted ​ ​ ​ ​ ​ ​ ​ ​ Prices ​ Other ​ ​ ​ ​ ​ ​ ​ ​ in Active ​ Observable ​ Unobservable ​ Total ​ ​ Markets ​ Inputs ​ Inputs ​ Fair (In Thousands) ​ (Level 1) ​ (Level 2) ​ (Level 3) ​ Value Recurring fair value measurements, assets: ​ ​ ​ ​ AVAILABLE-FOR-SALE DEBT SECURITIES: ​ ​ ​ ​ Obligations of the U.S. Treasury ​ $ 0 ​ $ 12,182 ​ $ 0 ​ $ 12,182 Obligations of U.S. Government agencies ​ ​ 0 ​ ​ 26,344 ​ ​ 0 ​ ​ 26,344 Obligations of states and political subdivisions: ​ ​ ​ ​ ​ ​ Tax-exempt ​ 0 ​ 122,401 ​ 0 ​ 122,401 Taxable ​ 0 ​ 47,452 ​ 0 ​ 47,452 Mortgage-backed securities issued or guaranteed by U.S. Government agencies or sponsored agencies: ​ ​ ​ ​ Residential pass-through securities ​ 0 ​ 38,176 ​ 0 ​ 38,176 Residential collateralized mortgage obligations ​ 0 ​ 57,467 ​ 0 ​ 57,467 Commercial mortgage-backed securities ​ 0 ​ 45,310 ​ 0 ​ 45,310 Total available-for-sale debt securities ​ 0 ​ 349,332 ​ 0 ​ 349,332 Marketable equity security ​ 1,000 ​ 0 ​ 0 ​ 1,000 Servicing rights ​ 0 ​ 0 ​ 1,689 ​ 1,689 Interest rate swap agreements, assets ​ ​ 0 ​ ​ 6,566 ​ ​ 0 ​ ​ 6,566 Total recurring fair value measurements, assets ​ $ 1,000 ​ $ 355,898 ​ $ 1,689 ​ $ 358,587 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Recurring fair value measurements, liabilities, ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Interest rate swap agreements, liabilities ​ $ 0 ​ $ 6,566 ​ $ 0 ​ $ 6,566 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nonrecurring fair value measurements, assets: ​ ​ ​ ​ Impaired loans with a valuation allowance ​ $ 0 ​ $ 0 ​ $ 8,082 ​ $ 8,082 Valuation allowance ​ 0 ​ 0 ​ (925) ​ (925) Impaired loans, net ​ 0 ​ 0 ​ 7,157 ​ 7,157 Foreclosed assets held for sale ​ 0 ​ 0 ​ 1,338 ​ 1,338 Total nonrecurring fair value measurements, assets ​ $ 0 ​ $ 0 ​ $ 8,495 ​ $ 8,495 ​ Management’s evaluation and selection of valuation techniques and the unobservable inputs used in determining the fair values of assets valued using Level 3 methodologies include sensitive assumptions.

At September 30, 2021 and December 31, 2020, quantitative information regarding valuation techniques and the significant unobservable inputs used for assets measured on a recurring basis using unobservable inputs (Level 3 methodologies) are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value at ​ ​ ​ 9/30/2021 ​ Valuation ​ Unobservable ​ ​ ​ ​ Method or Value As of Asset ​ (In Thousands) ​ Technique ​ Input(s) ​ ​ ​ ​ 9/30/2021 Servicing rights ​ $ 2,247 Discounted cash flow Discount rate ​ 13.00 % Rate used through modeling period ​ ​ ​ ​ ​ Loan prepayment speeds ​ ​ 221.00 % 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. Unrealized gains (losses) in fair value of servicing rights are included in Loan servicing fees, net, in the unaudited consolidated statements of income. Following is a reconciliation of activity for Level 3 assets measured at fair value on a recurring basis: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands) ​ Three Months Ended ​ Nine Months Ended ​ September 30, 2021 September 30, 2020 September 30, 2021 September 30, 2020 Servicing rights balance, beginning of period ​ $ 2,116 ​ $ 1,284 ​ $ 1,689 ​ $ 1,277 Originations of servicing rights ​ 176 ​ 374 ​ 567 ​ 777 Unrealized loss included in earnings ​ (45) ​ (221) ​ (9) ​ (617) Servicing rights balance, end of period ​ $ 2,247 ​ $ 1,437 ​ $ 2,247 ​ $ 1,437 ​ 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. 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. For commercial and industrial and agricultural 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. At September 30, 2021 and December 31, 2020, quantitative information regarding valuation techniques and the significant unobservable inputs used for nonrecurring fair value measurements using Level 3 methodologies are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (Dollars In Thousands) ​ ​ ​ ​ Weighted ​ ​ ​ ​ ​ Valuation ​ ​ ​ ​ ​ Average ​ ​ Balance at ​ Allowance at ​ Fair Value at ​ Valuation ​ Unobservable ​ Discount at Asset ​ 9/30/2021 ​ 9/30/2021 ​ 9/30/2021 ​ Technique ​ Inputs ​ 9/30/2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Impaired loans: ​ ​ ​ ​ Commercial: ​ ​ ​ ​ ​ ​ ​ Commercial loans secured by real estate ​ $ 6,480 ​ $ 672 ​ $ 5,808 Sales comparison Discount to appraised value 27 % Commercial and industrial ​ ​ 72 ​ ​ 72 ​ ​ 0 ​ Liquidation of assets Discount to appraised value 100 % Residential mortgage loans - first and junior liens ​ ​ 673 ​ ​ 139 ​ ​ 534 Sales comparison Discount to appraised value 33 % Total impaired loans ​ $ 7,225 ​ $ 883 ​ $ 6,342 ​ Foreclosed assets held for sale - real estate: ​ ​ ​ ​ Commercial real estate ​ $ 1,195 ​ $ 0 ​ $ 1,195 Sales comparison Discount to appraised value 47 % Residential (1-4 family) ​ ​ 179 ​ ​ 0 ​ ​ 179 Sales comparison Discount to appraised value 52 % Total foreclosed assets held for sale ​ $ 1,374 ​ $ 0 ​ $ 1,374 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (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. The estimated fair values, and related carrying amounts, of the Corporation’s financial instruments that are not recorded at fair value are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands) ​ Fair Value ​ September 30, 2021 ​ December 31, 2020 ​ ​ Hierarchy ​ Carrying ​ Fair ​ Carrying ​ Fair ​ Level Amount Value Amount Value Financial assets: ​ ​ ​ ​ Cash and cash equivalents Level 1 ​ $ 190,155 ​ $ 190,155 ​ $ 96,017 ​ $ 96,017 Certificates of deposit Level 2 ​ 8,840 ​ 8,949 ​ 5,840 ​ 6,054 Restricted equity securities (included in Other Assets) Level 2 ​ 9,650 ​ 9,650 ​ 9,970 ​ 9,970 Loans, net Level 3 ​ 1,563,008 ​ 1,586,592 ​ 1,632,824 ​ 1,646,207 Accrued interest receivable Level 2 ​ 7,307 ​ 7,307 ​ 8,293 ​ 8,293 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial liabilities: ​ ​ ​ ​ Deposits with no stated maturity Level 2 ​ 1,637,463 ​ 1,637,463 ​ 1,430,062 ​ 1,430,062 Time deposits Level 2 ​ 302,678 ​ 304,330 ​ 390,407 ​ 393,566 Short-term borrowings Level 2 ​ 1,875 ​ 1,685 ​ 20,022 ​ 19,974 Long-term borrowings Level 2 ​ 38,680 ​ 39,229 ​ 54,608 ​ 55,723 Senior debt ​ Level 2 ​ ​ 14,685 ​ ​ 15,000 ​ ​ 0 ​ ​ 0 Subordinated debt ​ Level 2 ​ ​ 32,988 ​ ​ 33,150 ​ ​ 16,553 ​ ​ 16,680 Accrued interest payable Level 2 ​ 633 ​ 633 ​ 390 ​ 390 ​ The Corporation has commitments to extend credit and has issued standby letters of credit.

NATURE OF OPERATIONS AND SUMMAR

NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
	Sep. 30, 2021
BASIS OF INTERIM PRESENTATION AND STATUS OF RECENT ACCOUNTING PRONOUNCEMENTS
RECENT ACCOUNTING PRONOUNCEMENTS	RECENT ACCOUNTING PRONOUNCEMENTS The Financial Accounting Standards Board (FASB) issues Accounting Standards Updates (ASUs) to the FASB Accounting Standards Codification (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 near 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 ASU 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 has formed a cross functional management team to evaluate and implement changes to contracts with rates indexed to LIBOR and expects to apply the amendments prospectively for applicable loan and other contracts within the effective period of ASU 2020-04.
