On December 8, 2017, the Bank completed its acquisition of the S&T Bank branch in State College (State College). On April 17, 2020, the Company completed its acquisition of MidCoast. As of December 31, 2020, the Bank operates full-service banking branches in Potter, Tioga, Bradford, Clinton, Lebanon, Lancaster, Berks, Schuylkill, Centre and Chester counties, Pennsylvania, Allegany County, New York, and the cities of Wilmington and Dover, Delaware, and a limited branch office in Union county, Pennsylvania. The Bank also provides trust services, including the administration of trusts and estates, retirement plans, and other employee benefit plans, along with a brokerage division that provides a comprehensive menu of investment services. The Bank serves individual and corporate customers and is subject to competition from other financial institutions and intermediaries with respect to these services. The Company and Bank are supervised by the Board of Governors of the Federal Reserve System, while the Bank is subject to additional regulation and supervision by the Pennsylvania Department of Banking A summary of significant accounting and reporting policies applied in the presentation of the accompanying financial statements follows: Basis of Presentation The financial statements are consolidated to include the accounts of the Company, and its subsidiary CZFS, and its st Use of Estimates In preparing the financial statements, management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses for the period. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change relate to determination of the allowance for loan losses, goodwill, derivatives, pension Operating Segments An operating segment is defined as a component of an enterprise that engages in business activities that generates revenue and incurs expense, and the operating results of which are reviewed by the chief operating decision maker in the determination of resource allocation and performance. While the Company’s chief decision makers monitor the revenue streams of the various Company’s products, services and regions, operations are managed and financial performance is evaluated on a Company-wide basis. Consistent with our internal reporting, the Company’s business activities are reported as one segment, which is community banking. Cash and Cash Equivalents Cash equivalents include cash on hand, deposits in banks and interest-earning deposits. Interest-earning deposits with original maturities of 90 days or less are considered cash equivalents. Interest bearing time deposits with other banks are not included with cash and cash equivalents as the original maturities were greater than 90 days. Investment Securities Investment securities at the time of purchase are classified as one of the three following types: Held-to-Maturity Securities Trading Securities Available-for-Sale Securities This category included debt securities not classified as held-to-maturity or trading securities that will be held for indefinite periods of time. These securities may be sold in response to changes in market interest or prepayment rates, needs for liquidity and changes in the availability of and yield of alternative investments. Such securities are reported at fair value, with unrealized holding gains and losses excluded from earnings and reported as a separate component of stockholders’ equity, net of the estimated income tax effect The amortized cost of investment in debt securities is adjusted for amortization of premiums and accretion of discounts, computed by a method that results in a level yield. Gains and losses on the sale of investment securities are computed on the basis of specific identification of the adjusted cost of each security. Debt securities are periodically reviewed for other-than-temporary impairment. Management considers whether the present value of future cash flows expected to be collected are less than the security’s amortized cost basis (the difference defined as the credit loss), the magnitude and duration of the decline, the reasons underlying the decline and the Company’s intent to sell the security or whether it is more likely than not that the Company would be required to sell the security before its anticipated recovery in market value, to determine whether the loss in value is other than temporary. Once a decline in value is determined to be other than temporary, if the Company does not intend to sell the security, and it is more-likely-than-not that it will not be required to sell the security, before recovery of the security’s amortized cost basis, the charge to earnings is limited to the amount of credit loss. Any remaining difference between fair value and amortized cost (the difference defined as the non-credit portion) is recognized in other comprehensive income, net of applicable taxes. Otherwise, the entire difference between fair value and amortized cost is charged to earnings. The fair value of investments, except certain state and municipal securities, is based on bid prices published in financial newspapers or bid quotations received from securities dealers. The fair value of certain state and municipal securities is not readily available through market sources other than dealer quotations, so fair value is based on quoted market prices of similar instruments, adjusted for differences between the quoted instruments and the instruments being valued. Equity Securities – This category includes common stocks of public companies. Such securities are reported at fair value with unrealized holding gains and losses included in earnings Restricted Stock Loans Held for Sale Certain newly originated fixed-rate residential mortgage loans are classified as held for sale, because it is management’s intent to sell these residential mortgage loans. The residential mortgage loans held for sale are carried at the lower of aggregate cost or fair value. Loans Interest on all loans is recognized on the accrual basis based upon the principal amount outstanding. The accrual of interest income on loans is discontinued when, in the opinion of management, doubt exists as to the ability to collect such interest. Payments received on non-accrual loans are applied to the outstanding principal balance or recorded as interest income, depending upon our assessment of our ultimate ability to collect principal and interest. Loans are returned to the accrual status when factors indicating doubtful collectability cease to exist. The Company recognizes nonrefundable loan origination fees, SBA fees and certain direct loan origination costs over the life of the related loan as an adjustment of loan yield using the interest method. Allowance for Loan Losses The allowance for loan losses represents the amount which management estimates is adequate to provide for probable losses inherent in the Company’s loan portfolio. The allowance method is used in providing for loan losses. Accordingly, all loan losses are charged to the allowance and all recoveries are credited to it. The allowance for loan losses is established through a provision for loan losses which is charged to operations. The provision is based upon management’s periodic evaluation of individual loans, the overall risk characteristics of the various portfolio segments, past experience with losses, the impact of economic conditions on borrowers, and other relevant factors. The estimates used in determining the adequacy of the allowance for loan losses are particularly susceptible to significant change in the near term. Impaired loans are other commercial, other agricultural, municipal, agricultural real estate, commercial real estate loans and certain residential mortgages cross collateralized with commercial relationships for which it is probable that the Company will not be able to collect all amounts due according to the contractual terms of the loan agreement. The Company individually evaluates such loans for impairment and does not aggregate loans by major risk classifications. The definition of “impaired loans” is not the same as the definition of “non-accrual loans,” although the two categories overlap. The Company may choose to place a loan on non-accrual status due to payment delinquency or uncertain collectability, while not classifying the loan as impaired if the loan is not a commercial, agricultural, municipal or commercial real estate loan. Factors considered by management in determining impairment include payment status and collateral value. The amount of impairment for these types of impaired loans is determined by the difference between the present value of the expected cash flows related to the loan, using the original interest rate, and its recorded value; or, as a practical expedient in the case of a collateral dependent loan, the difference between the fair value of the collateral and the recorded amount of the loans. Mortgage loans on one to four family properties and all consumer loans are large groups of smaller balance homogeneous loans and are measured for impairment collectively. Loans that experience insignificant payment delays, which is defined as 90 days or less, generally are not classified as impaired. Management determines the significance of payment delays 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 borrower’s prior payment record, and the amount of shortfall in relation to the principal and interest owed. The Company allocates the allowance based on the factors described below, which conform to the Company’s loan classification policy. In reviewing risk within the loan portfolio, management has determined there to be several different risk categories within the loan portfolio. The allowance for loan losses consists of amounts applicable to: (i) residential real estate loans; (ii) commercial real estate (iii) agricultural real estate loans; (iv) construction; (v) consumer loans; (vi) other commercial loans (vii) other agricultural loans and (viii) state and political subdivision loans. Factors considered in this process include general loan terms, collateral, and availability of historical data to support the analysis. Historical loss percentages for each risk category are calculated and used as the basis for calculating allowance allocations. Certain qualitative factors are evaluated to determine additional inherent risks in the loan portfolio, which are not necessarily reflected in the historical loss percentages. These factors are then added to the historical allocation percentage to get the adjusted factor to be applied to non classified loans. The following qualitative factors are analyzed: • Level of and trends in delinquencies, impaired/classified loans • Change in volume and severity of past due loans • Volume of non-accrual loans • Volume and severity of classified, adversely or graded loans • Level of and trends in charge-offs and recoveries • Trends in volume, terms and nature of the loan portfolio • Effects of any changes in risk selection and underwriting standards and any other changes in lending and recovery policies, procedures and practices • Changes in the quality of the Bank’s loan review system • Experience, ability and depth of lending management and other relevant staff • National, state, regional and local economic trends and business conditions • General economic conditions • Unemployment rates • Inflation / CPI • Changes in values of underlying collateral for collateral-dependent loans • Industry conditions including the effects of external factors such as competition, legal, and regulatory requirements on the level of estimated credit losses. • Existence and effect of any credit concentrations, and changes in the level of such concentrations • Any change in the level of board oversight The Company analyzes its loan portfolio each quarter to determine the appropriateness of its allowance for loan losses. Loan Charge-off Policies Consumer loans are generally fully or partially charged down to the fair value of collateral securing the asset when the loan is 180 days past due for open-end loans or 120 days past due for closed-end loans unless the loan is well secured and in the process of collection. All other loans are generally charged down to the net realizable value when the loan is 90 days past due. Troubled Debt Restructurings In situations where, for economic or legal reasons related to a borrower's financial difficulties, management may grant a concession for other than an insignificant period of time to the borrower that would not otherwise be considered, the related loan is classified as a Troubled Debt Restructuring (TDR). Management strives to identify borrowers in financial difficulty early and work with them to modify more affordable terms before their loan reaches nonaccrual status. These modified terms may include rate reductions, principal forgiveness, payment forbearance and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of the collateral. In cases where borrowers are granted new terms that provide for a reduction of either interest or principal, management measures any impairment on the restructuring as noted above for impaired loans. In addition to the allowance for the pooled portfolios, management has developed a separate allowance for loans that are identified as impaired through a TDR. TDRs are excluded from pooled loss forecasts and a separate reserve is provided under the accounting guidance for loan impairment. Purchased Credit Impaired Loans The Company purchased loans in connection with its acquisitions of FNB in 2015, the State College branch in 2017 and MidCoast in 2020, some Such PCI loans are accounted for individually, and the Company estimates the amount and timing of expected cash flows for each loan. The expected cash flows in excess of the amount paid is recorded as interest income over the remaining life of the loan (accretable yield). The excess of the loan’s contractual principal and interest over expected cash flows is not amortized over the remaining life of the loan (nonaccretable difference). For loans purchased that did not show evidence of credit deterioration, the difference between the fair value of the loan at the acquisition date and the loan’s face value is being amortized as a yield adjustment over the estimated remaining life of the loan using the effective interest method. Foreclosed Assets Held For Sale Foreclosed assets acquired in settlement of loans are carried at fair value, less estimated costs to sell. Prior to foreclosure, as the value of the underlying loan is written down to fair market value of the real estate or other assets to be acquired by a charge to the allowance for loan losses, if necessary. Any subsequent write-downs are charged against operating expenses. Operating expenses of such properties, net of related income and losses on disposition, are included in other expenses and gains and losses are included in other non-interest income or other non-interest expense. Premises and Equipment Land is carried at cost. Premises and equipment are stated at cost, less accumulated depreciation. Depreciation expense is computed on straight line and accelerated methods over the estimated useful lives of the assets, which range from 3 to 15 years for furniture, fixtures and equipment and 5 to 40 years for building premises. Repair and maintenance expenditures which extend the useful life of an asset are capitalized and other repair expenditures are expensed as incurred. When premises or equipment are retired or sold, the remaining cost and accumulated depreciation are removed from the accounts and any gain or loss is credited to income or charged to expense, respectively. The Company has operating leases for several branch locations. Generally, the underlying lease agreements do not contain any material residual value guarantees or material restrictive covenants. The Company may also lease certain office equipment under operating leases. Many of our leases include both lease (e.g., minimum rent payments) and non-lease components (e.g., common-area or other maintenance costs). The Company accounts for each component separately based on the standalone price of each component. In addition, there are several operating leases with lease terms of less than one year and therefore, we have elected the practical expedient to exclude these short-term leases from our right of use (ROU) assets and lease liabilities. Most leases include one or more options to renew. The exercise of lease renewal options is typically at the sole discretion of management and is based on whether the extension options are reasonably certain to be exercised after giving proper consideration to all facts and circumstances of the lease. If management determines that the Company is reasonably certain to exercise the extension option(s), the additional term is included in the calculation of the lease liability. As most of our leases do not provide an implicit rate, we use the fully collateralized FHLB borrowing rate, commensurate with the lease terms based on the information available at the lease commencement date in determining the present value of the lease payments Intangible Assets Intangible assets, other than goodwill, include core deposit intangibles and mortgage servicing rights (MSRs). Core deposit intangibles are a measure of the value of consumer demand and savings deposits acquired in business combinations accounted for as purchases MSRs arise from the Company originating certain loans for the express purpose of selling such loans in the secondary market. The Company maintains all servicing rights for these loans. The loans held for sale are carried at lower of cost or market. Originated MSRs are recorded by allocating total costs incurred between the loan and servicing rights based on their relative fair values. MSRs are amortized in proportion to the estimated servicing income over the estimated life of the servicing portfolio and measured annually for impairment. The recoverability of the carrying value of intangible assets is evaluated on an ongoing basis, and permanent declines in value, if any, are charged to expense. Goodwill The Company utilizes a two-step process for testing the impairment of goodwill on at least an annual basis. This approach could cause more volatility in the Company’s reported net income because impairment losses, if any, could occur irregularly and in varying amounts. The Company may also perform a qualitative assessment to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying value. Based on the fair value of the reporting unit, no impairment of goodwill was recognized in 2020, 2019 or 2018. Bank Owned Life Insurance The Company has purchased life insurance policies on certain employees. Any death benefits received from a policy while the insured person is an active employee of the Bank will be split with the beneficiary of the policy. Under these agreements, the Bank receives the cash surrender value of the policy the benefit in excess of the cash surrender value and the remaining amount of the payout will be given to the beneficiary named by the insured person in the policy. The Company is the sole beneficiary of any death benefits received from non-active insured persons. Additionally, as a result of the MidCoast acquisition, the Company acquired life insurance policies on former MidCoast employees. The Company is owner and sole beneficiary of these policies. The Company acquired life insurance policies on former FNB employees and directors, as part of the acquisition of FNB. The policies obtained as part of the acquisition provide a fixed dollar benefit to the former employee or director beneficiaries, whether or not the insured person is affiliated with the Company at the time of his or her death. Bank owned life insurance is recorded at its cash surrender value, or the amount that can be realized. Increases in the cash surrender value are recognized as other non-interest income Income Taxes The Company and the Bank file a consolidated federal income tax return. Deferred tax assets and liabilities are computed based on the difference between the financial statement basis and income tax basis of assets and liabilities using the enacted marginal tax rates. Deferred income tax expenses or benefits are based on the changes in the net deferred tax asset or liability from period to period. Derivatives Derivative financial instruments are recognized as assets or liabilities at fair value. The Company has interest rate swap agreements which are used as part of its asset liability management to help manage interest rate risk. The Corporation does not use derivatives for trading purposes. At the inception of a derivative contract, the Company designates the derivative as one of types based on the purpose of the contract and belief as to its effectiveness as a hedge. These three types are (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (“fair value hedge”), (2) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedge”), or (3) an instrument with no hedging designation (“stand-alone derivative”). For a fair value hedge, the gain or loss on the derivative, as well as the offsetting loss or gain on the hedged item, are recognized in current earnings as fair values change. For a cash flow hedge, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same periods during which the hedged transaction affects earnings. For both types of hedges, changes in the fair value of derivatives that are not highly effective in hedging the changes in fair value or expected cash flows of the hedged item are recognized immediately in current earnings. Changes in the fair value of derivatives that do not qualify for hedge accounting are reported currently in earnings, as non-interest income. Net cash settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in non-interest income. Cash flows on hedges are classified in the cash flow statement the same as the cash flows of the items being hedged. The Company formally documents the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions, at the inception of the hedging relationship. This documentation includes linking fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used are highly effective in offsetting changes in fair values or cash flows of the hedged items. The Company discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm, or treatment of the derivative as a hedge is no longer appropriate or intended. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as non-interest income. When a fair value hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted over the remaining life of the asset or liability. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that were accumulated in other comprehensive income are amortized into earnings over the same periods which the hedged transactions will affect earnings. Employee Benefit Plans The Company has noncontributory defined benefit pension plans covering employees hired before January 1, 2007 and employees acquired as part of the FNB acquisition. It is the Company’s policy to fund pension costs on a current basis to the extent deductible under existing tax regulations. Such contributions are intended to provide not only for benefits attributed to service to date, but also for those expected to be earned in the future. The plan acquired as part of the FNB acquisition was terminated in 2019. The Company has a defined contribution, 401(k) plan covering eligible employees. The employee may also contribute to the plan on a voluntary basis, up to a maximum percentage allowable not to exceed the limits of Code Sections 401(k). Under the plan, the Company also makes contributions on behalf of eligible employees, which vest immediately. For employees hired after January 1, 2007, in lieu of the pension plan, an additional annual discretionary 401(k) plan contribution is made and is equal to a percentage of an employee’s base compensation. The Company also has a profit-sharing plan for employees which provide tax-deferred salary savings to plan participants. The Company has a deferred compensation plan for directors who have elected to defer all or portions of their fees until their retirement or termination from service. The Company has a restricted stock plan which covers eligible employees and non-employee corporate directors. Under the plan, awards are granted based upon performance related requirements and are subject to certain vesting criteria. Compensation cost related to restricted stock is recognized based on the market price of the stock at the grant date over the vesting period. The Company has an employee stock purchase plan that allows employees to withhold money from their paychecks, which is then utilized to purchase shares of the Company’s stock on either the open market or through treasury stock, if shares are unavailable on the open market. The Company maintains a non-qualified supplemental executive retirement plan (“SERP”) for certain executives to compensate those executive participants in the Company’s noncontributory defined benefit pension plan whose benefits are limited by compensation limitations under current tax law. The SERP is considered an unfunded plan for tax and ERISA purposes and all obligations arising under the SERP are payable from the general assets of the Company. Expenses under the SERP are recognized as earned over the expected years of service. The Company maintains a non-tax qualified executive deferred compensation plan (“Deferred Compensation Plan”) for eligible employees designated by the board of directors. Each of the named executive officers are eligible to participate in the Deferred Compensation Plan. The Deferred Compensation Plan is considered an unfunded plan for tax and ERISA purposes and all obligations arising under the Deferred Compensation Plan are payable from the general assets of the Company. Expenses under the Deferred Compensation Plan are recognized as earned over the expected years of service. Advertising Costs Advertising costs are generally expensed as incurred and amounted to $470,000, $466,000 and $361,000 for the years ended December 31, 2020, 2019 and 2018, respectively. Comprehensive Income (Loss) The Company is required to present comprehensive income in a full set of general purpose financial statements for all periods presented. Other comprehensive income (loss) is comprised of unrealized holding gains (losses) on the available-for-sale securities portfolio and unrecognized pension costs.

REVENUE RECOGNITION

REVENUE RECOGNITION [Abstract]
REVENUE RECOGNITION	2. REVENUE RECOGNITION Under ASC Topic 606, management determined that the primary sources of revenue emanating from interest and dividend income on loans and investments along with noninterest revenue resulting from investment security gains, loan servicing, gains on loans sold and earnings on bank owned life insurances are not within the scope of this topic. The main types of noninterest income within the scope of the standard are as follows: • Service charges on deposit accounts – The Company has contracts with its deposit customers where fees are charged if certain parameters are not met. These agreements can be cancelled at any time by either the Company or the deposit customer. Revenue from these transactions is recognized on a monthly basis as the Company has an unconditional right to the fee consideration. The Company also has transaction fees related to specific transactions or activities resulting from a customer request or activity that include overdraft fees, online banking fees, interchange fees, ATM fees and other transaction fees. All of these fees are attributable to specific performance obligations of the Company where the revenue is recognized at a defined point in time upon the completion of the requested service/transaction. • Trust fees – Typical contracts for trust services are based on a fixed percentage of the assets earned ratably over a defined period and billed on a monthly basis. Fees charged to customers’ accounts are recognized as revenue over the period during which the Company fulfills its performance obligation under the contract (i.e., holding client asset in a managed fiduciary trust account). For these accounts, the performance obligation of the Company is typically satisfied by holding and managing the customer’s assets over time. Other fees related to specific customer requests are attributable to specific performance obligations of the Company where the revenue is recognized at a defined point in time, upon completion of the requested service/transaction. • Gains (losses) on sale of other real estate owned – Gains and losses are recognized at the completion of the property sale when the buyer obtains control of the real estate and all of the performance obligations of the Company have been satisfied. Evidence of the buyer obtaining control of the asset include transfer of the property title, physical possession of the asset, and the buyer obtaining control of the risks and rewards related to the asset. In situations where the Company agrees to provide financing to facilitate the sale, additional analysis is performed to ensure that the contract for sale identifies the buyer and seller, the asset to be transferred, payment terms, and that the contract has a true commercial substance and that collection of amounts due from the buyer are reasonable. In situations where financing terms are not reflective of current market terms, the transaction price is discounted impacting the gain/loss and the carrying value of the asset. • Brokerage and insurance – Fees includes commissions from the sales of investments and insurance products recognized on a trade date basis as the performance obligation is satisfied at the point in time in which the trade is processed. Additional fees are based on a percentage of the market value of customer accounts and billed on a monthly or quarterly basis. The Company’s performance obligation under the contracts with certain customers is generally satisfied through the passage of time as the Company monitors and manages the assets in the customer’s portfolio and is not dependent on certain return or performance level of the customer’s portfolio. Fees for these services are billed monthly and are recorded as revenue at the end of the month for which the wealth management service has been performed. Other performance obligations (such as the delivery of account statements to customers) are generally considered immaterial to the overall transaction price. The following table depicts the disaggregation of revenue derived from contracts with customers to depict the nature, amount, timing, and uncertainty of revenue and cash flows for the years ended December 31, 2020, 2019 and 2018 (in thousands).

For fixed maturity available for sale investments management considers whether the present value of cash flows expected to be collected are less than the security’s amortized cost basis (the difference defined as the credit loss), the magnitude and duration of the decline, the reasons underlying the decline and the Company’s intent to sell the security or whether it is more likely than not that the Company would be required to sell the security before its anticipated recovery in market value, to determine whether the loss in value is other than temporary. Once a decline in value is determined to be other than temporary, if the Company does not intend to sell the security, and it is more-likely-than-not that it will not be required to sell the security, before recovery of the security’s amortized cost basis, the charge to earnings is limited to the amount of credit loss. Any remaining difference between fair value and amortized cost (the difference defined as the non-credit portion) is recognized in other comprehensive income, net of applicable taxes. Otherwise, the entire difference between fair value and amortized cost is charged to earnings. As of December 31, 2020 and 2019, the Company had concluded that any impairment of its investment securities portfolio outlined in the above table is not other than temporary and is the result of interest rate changes, sector credit rating changes, or company-specific rating changes that are not expected to result in the non-collection of principal and interest during the period. Proceeds from sales of securities available-for-sale during 2020, 2019 and 2018 were $23,415,000, $10,489,000 and $27,149,000, respectively. The gross gains realized during 2020 consisted of $344,000 from the sales of seventeen mortgage backed securities. The gross losses realized during 2020 consisted of $39,000 from the sale of two mortgage backed securities. The gross gains realized during 2019 consisted of $1,000 and $24,000 from the sales of two agency securities and four treasury securities, respectively. The gross losses realized during 2019 consisted of $1,000 from the sale of one agency security. The gross gains realized during 2018 consisted of $160,000 from the sale of fourteen municipal securities. The gross losses realized during 2018 consisted of $179,000 from the sale of seven agency securities. Gross gains and gross losses were realized as follows on available for sale securities (in thousands): 2020 2019 2018 Gross gains $ 344 $ 25 $ 160 Gross losses (39 ) (1 ) (179 ) Net (losses) gains $ 305 $ 24 $ (19 ) The following table presents the net (losses) gains on the Company’s equity investments recognized in earnings during 2020, 2019 and 2019 and the portion of unrealized gains for the period that relates to equity investments held at December 31, 2020 and 2019 (in thousands): Equity Securities 2020 2019 2018 Net gains (losses) recognized in equity securities during the period $ (109 ) $ 120 $ - Less: Net gains realized on the sale of equity securities during the period 68 - - Net unrealized gains (losses) $ (41 ) $ 120 $ - Investment securities with an approximate carrying value of $245,351,000 and $209,096,000 at December 31, 2020 and 2019, respectively, were pledged to secure public funds and certain other deposits as provided by law and certain borrowing arrangements of the Company. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

LOANS AND RELATED ALLOWANCE FOR LOAN LOSSES [Abstract]
LOANS AND RELATED ALLOWANCE FOR LOAN LOSSES	5. LOANS AND RELATED ALLOWANCE FOR LOAN LOSSES The Company grants commercial, industrial, agricultural, residential, and consumer loans primarily to customers throughout north central, central and south central Pennsylvania, southern New York and Wilmington and Dover, Delaware. Although the Company had a diversified loan portfolio at December 31, 2020 and 2019, a substantial portion of its debtors’ ability to honor their contracts is dependent on the economic conditions within these regions. The following table summarizes the primary segments of the loan portfolio, as well as how those segments are analyzed within the allowance for loan losses as of December 31, 2020 and 2019 (in thousands): 2020 Total Loans Individually evaluated for impairment Loans acquired with deteriorated credit quality Collectively evaluated for impairment Real estate loans: Residential $ 201,911 $ 990 $ 20 $ 200,901 Commercial 596,255 9,183 2,937 584,135 Agricultural 315,158 4,645 1,686 308,827 Construction 35,404 - - 35,404 Consumer 30,277 2 - 30,275 Other commercial loans 114,169 1,335 232 112,602 Other agricultural loans 48,779 1,122 - 47,657 State and political subdivision loans 63,328 - - 63,328 Total 1,405,281 17,277 4,875 1,383,129 Allowance for loan losses 15,815 510 - 15,305 Net loans $ 1,389,466 $ 16,767 $ 4,875 $ 1,367,824 2019 Total Loans Individually evaluated for impairment Loans acquired with deteriorated credit quality Collectively evaluated for impairment Real estate loans: Residential $ 217,088 $ 1,166 $ 23 $ 215,899 Commercial 342,023 11,537 1,210 329,276 Agricultural 311,464 3,782 - 307,682 Construction 15,519 - - 15,519 Consumer 9,947 4 - 9,943 Other commercial loans 69,970 1,902 49 68,019 Other agricultural loans 55,112 1,281 - 53,831 State and political subdivision loans 94,446 - - 94,446 Total 1,115,569 19,672 1,282 1,094,615 Allowance for loan losses 13,845 735 - 13,110 Net loans $ 1,101,724 $ 18,937 $ 1,282 $ 1,081,505 During 2020 the Company participated in the Paycheck Protection Program (“PPP”), administered directly by the U.S. SBA. The PPP provides loans to small businesses who were affected by economic conditions as a result of COVID-19 to provide cash-flow assistance to employers who maintain their payroll (including healthcare and certain related expenses), mortgage interest, rent, leases, utilities and interest on existing debt during the COVID-19 emergency. The Company originated $ million of loans under this program. The PPP loans are fully guaranteed by the SBA, have an interest rate of per annum, and may be eligible for forgiveness by the SBA to the extent that the proceeds are used to cover eligible payroll costs, interest costs, rent, and utility costs over a period of up to 24 weeks after the loan is made as long as certain conditions are met regarding employee retention and compensation levels. PPP loans deemed eligible for forgiveness by the SBA will be repaid by the SBA to the Company. The SBA has issued guidance for forgiveness with a streamlined approach for loans of $ or less. During 2020, we received payments and forgiveness on loans totaling $ million with loans being completely paid off or forgiven by December 31, 2020. PPP loans are included in the other commercial loan category and total $ million as of December 31, 2020. In accordance with the SBA terms and conditions on these PPP loans, the Company received approximately $ million in fees associated with the processing of these loans. Upon funding of the loan, these fees were deferred and will be amortized over the life of the loan as an adjustment to yield in accordance with FASB ASC 310-20-25-2. As of December 31, 2020, $ million of deferred fees remain to be amortized related to the PPP loans. As of December 31, 2020 and 2019, net unamortized loan fees, including PPP fees, and costs of $ and $ , respectively, were included in the carrying value of loans. Purchased loans acquired in connection with the FNB acquisition, the State College branch acquisition and the MidCoast acquisition were recorded at fair value on their acquisition date without a carryover of the related allowance for loan losses. Upon acquisition, the Company evaluated whether an acquired loan was within the scope of ASC 310-30, Receivables-Loans and Debt Securities Acquired with Deteriorated Credit Quality. PCI loans are loans that have evidence of credit deterioration since origination and it is probable at the date of acquisition that the Company will not collect all contractually required principal and interest payments. The fair value of PCI loans, on the acquisition date, was determined, primarily based on the fair value of the loans’ collateral. The carrying value of PCI loans was $4,875,000 and $1,282,000 at December 31, 2020 and 2019, respectively. The carrying value of the PCI loans was determined by projected discounted contractual cash flows. On the acquisition date, the preliminary estimate of the unpaid principal balance for all loans evidencing credit impairment acquired in the MidCoast acquisition was $8,005,000 and the estimated fair value of the loans was $4,869,000. Total contractually required payments on these loans, including interest, at the acquisition date was $8,801,000. However, the Company’s preliminary estimate of expected cash flows was $5,835,000 at the acquisition date. At the acquisition date, the Company established a credit risk related non-accretable discount (a discount representing amounts which are not expected to be collected from the customer nor liquidation of collateral) of $2,966,000 relating to these impaired loans, reflected in the recorded net fair value. Such amount is reflected as a non-accretable fair value adjustment to loans. The Company further estimated the timing and amount of expected cash flows in excess of the estimated fair value and established an accretable discount of $966,000 on the acquisition date relating to these impaired loans. The table below presents the components of the purchase accounting adjustments related to the purchased impaired loans acquired in the MidCoast Acquisition as of (in thousands): April 17, 2020 Contractually required principal and interest at acquisition $ 8,801 Non-accretable discount (2,966 ) Expected cash flows 5,835 Accretable discount (966 ) Estimated fair value $ 4,869 Changes in the accretable discount for PCI loans were as follows for the years ended December 31, 2020 and 2019 (in thousands): December 31, 2020 December 31, 2019 Balance at beginning of period $ 89 $ 104 Addition due to MidCoast Acquisition 966 - Accretion (267 ) (15 ) Balance at end of period $ 788 $ 89 The following table presents additional information regarding PCI loans (in thousands): December 31, 2020 December 31, 2019 Outstanding balance $ 8,958 $ 4,072 Carrying amount 4,875 1,282 Real estate loans serviced for Freddie Mac, Fannie Mae and the FHLB, which are not included in the Consolidated Balance Sheet, totaled $178,986,000 and $148,889,000 at December 31, 2020 and 2019, respectively. Loans sold to Freddie Mac and Fannie Mae were sold without recourse and total $162,050,000 and $127,402,000 at December 31, 2020 and 2019, respectively. Additionally, the Bank acquired a portfolio of loans sold to the FHLB during the acquisition of FNB, which were sold under the Mortgage Partnership Finance Program ("MPF"). The Bank was not an active participant in the MPF program in 2020 or 2019. The MPF portfolio balance was $16,936,000 and $21,487,000 at December 31, 2020 and 2019, respectively. The FHLB maintains a first-loss position for the MPF portfolio that totals $151,000. Should the FHLB exhaust its first-loss position, recourse to the Bank's credit enhancement would be up to the next $764,000 of losses. The Bank did not experience any losses for the MPF portfolio during 2020, 2019 or 2018. The segments of the Bank’s loan portfolio are disaggregated into classes to a level that allows management to monitor risk and performance. Residential real estate mortgages consists of 15 to 30 year first mortgages on residential real estate, while residential real estate home equities are consumer purpose installment loans or lines of credit secured by a mortgage which is often a second lien on residential real estate with terms of 15 years or less. Commercial real estate are business purpose loans secured by a mortgage on commercial real estate. Agricultural real estate are loans secured by a mortgage on real estate used in agriculture production. Construction real estate are loans secured by residential or commercial real estate used during the construction phase of residential and commercial projects. Consumer loans are typically unsecured or primarily secured by collateral other than real estate and overdraft lines of credit connected with customer deposit accounts. Other commercial loans are loans for commercial purposes primarily secured by non-real estate collateral. Other agricultural loans are loans for agricultural purposes primarily secured by non real estate collateral. State and political subdivisions are loans for state and local municipalities for capital and operating expenses or tax free loans used to finance commercial development. Management considers other commercial loans, other agricultural loans, commercial and agricultural real estate loans and state and political subdivision loans which are 90 days or more past due to be impaired. Certain residential mortgages, home equity and consumer loans that are cross collateralized with commercial relationships determined to be impaired may be classified as impaired as well. These loans are analyzed to determine if it is probable that all amounts will not be collected according to the contractual terms of the loan agreement. If management determines that the value of the impaired loan is less than the recorded investment in the loan (net of previous charge-offs, deferred loan fees or costs and unamortized premium or discount), impairment is recognized through an allowance allocation or a charge-off to the allowance. The following table includes the recorded investment and unpaid principal balances for impaired loans by class, with the associated allowance amount as of December 31, 2020 and 2019, if applicable (in thousands): Unpaid Principal Balance Recorded Investment With No Allowance Recorded Investment With Allowance Total Recorded Investment Related Allowance 2020 Real estate loans: Mortgages $ 1,070 $ 740 $ 123 $ 863 $ 9 Home Equity 150 70 57 127 9 Commercial 9,847 8,323 860 9,183 95 Agricultural 4,811 2,799 1,846 4,645 83 Construction - - - - - Consumer 2 2 - 2 - Other commercial loans 1,908 1,094 241 1,335 170 Other agricultural loans 1,262 19 1,103 1,122 144 Total $ 19,050 $ 13,047 $ 4,230 $ 17,277 $ 510 Unpaid Principal Balance Recorded Investment With No Allowance Recorded Investment With Allowance Total Recorded Investment Related Allowance 2019 Real estate loans: Mortgages $ 1,212 $ 794 $ 223 $ 1,017 $ 20 Home Equity 170 83 66 149 12 Commercial 12,070 10,723 814 11,537 251 Agricultural 3,900 1,580 2,202 3,782 151 Construction - - - - - Consumer 4 4 - 4 - Other commercial loans 2,517 1,555 347 1,902 147 Other agricultural loans 1,347 126 1,155 1,281 154 Total $ 21,220 $ 14,865 $ 4,807 $ 19,672 $ 735 The following table includes the average investment in impaired loans and the income recognized on impaired loans for 2020, 2019 and 2018 (in thousands): Interest Average Interest Income Recorded Income Recognized 2020 Investment Recognized Cash Basis Real estate loans: Mortgages $ 956 $ 20 $ - Home Equity 139 6 - Commercial 10,354 358 27 Agricultural 3,918 75 - Consumer 3 - - Other commercial loans 1,671 3 - Other agricultural loans 1,237 6 - Total $ 18,278 $ 468 $ 27 2019 Average Recorded Investment Interest Income Recognized Interest Income Recognized Cash Basis Real estate loans: Mortgages $ 1,062 $ 16 $ - Home Equity 119 6 - Commercial 11,756 453 24 Agricultural 4,899 78 - Consumer 2 - - Other commercial loans 2,056 1 - Other agricultural loans 1,400 4 - Total $ 21,294 $ 558 $ 24 2018 Average Recorded Investment Interest Income Recognized Interest Income Recognized Cash Basis Real estate loans: Mortgages $ 944 $ 13 $ - Home Equity 95 4 - Commercial 13,907 506 20 Agricultural 4,736 151 - Consumer 1 - - Other commercial loans 3,659 89 - Other agricultural loans 1,401 23 - Total $ 24,743 $ 786 $ 20 Credit Quality Information For commercial real estate loans, agricultural real estate loans, construction loans, other commercial loans, other agricultural loans and state and political subdivision loans, management uses a nine point internal risk rating system to monitor the credit quality. The first five categories are considered not criticized and are aggregated as “Pass” rated. The criticized rating categories utilized by management generally follow bank regulatory definitions. The definitions of each rating are defined below: • Pass (Grades 1-5) – These loans are to customers with credit quality ranging from an acceptable to very high quality and are protected by the current net worth and paying capacity of the obligor or by the value of the underlying collateral. • Special Mention (Grade 6) – This loan grade is in accordance with regulatory guidance and includes loans where a potential weakness or risk exists, which could cause a more serious problem if not corrected. • Substandard (Grade 7) – This loan grade is in accordance with regulatory guidance and includes loans that have a well-defined weakness based on objective evidence and are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. • Doubtful (Grade 8) – This loan grade is in accordance with regulatory guidance and includes loans that have all the weaknesses inherent in a substandard asset. In addition, these weaknesses make collection or liquidation in full highly questionable and improbable, based on existing circumstances. • Loss (Grade 9) – This loan grade is in accordance with regulatory guidance and includes loans that are considered uncollectible, or of such value that continuance as an asset is not warranted. To help ensure that risk ratings are accurate and reflect the present and future capacity of borrowers to repay the loan as agreed, the Company’s loan rating process includes several layers of internal and external oversight. The Company’s loan officers are responsible for the timely and accurate risk rating of the loans in each of their portfolios at origination and on an ongoing basis under the supervision of management. All commercial and agricultural loans are reviewed annually to ensure the appropriateness of the loan grade. In addition, the Company engages an external consultant on at least an annual basis. The external consultant is engaged to 1) review a minimum of 50% of the dollar volume of the commercial loan portfolio on an annual basis, 2) review new loans originated over $1.0 million in the last years, 3) review a majority of borrowers with commitments greater than or equal to $1.0 million, 4) review selected loan relationships over $750,000 which are over 30 days past due, or classified Special Mention, Substandard, Doubtful, or Loss, and 5) such other loans which management or the consultant deems appropriate. The following tables represent credit exposures by internally assigned grades as of December 31, 2020 and 2019 (in thousands): 2020 Pass Special Mention Substandard Doubtful Loss Ending Balance Real estate loans: Commercial $ 563,121 $ 24,329 $ 8,805 $ - $ - $ 596,255 Agricultural 289,216 14,307 11,635 - - 315,158 Construction 35,404 - - - - 35,404 Other commercial loans 106,604 3,808 3,672 85 - 114,169 Other agricultural loans 45,758 1,431 1,590 - - 48,779 State and political subdivision loans 58,649 4,372 307 - - 63,328 Total $ 1,098,752 $ 48,247 $ 26,009 $ 85 $ - $ 1,173,093 2019 Pass Special Mention Substandard Doubtful Loss Ending Balance Real estate loans: Commercial $ 329,831 $ 4,305 $ 7,848 $ 39 $ - $ 342,023 Agricultural 287,044 14,261 10,159 - - 311,464 Construction 15,519 - - - - 15,519 Other commercial loans 66,880 984 2,042 64 - 69,970 Other agricultural loans 51,711 1,077 2,324 - - 55,112 State and political subdivision loans 93,993 - 453 - - 94,446 Total $ 844,978 $ 20,627 $ 22,826 $ 103 $ - $ 888,534 For residential real estate mortgages, home equities and consumer loans, credit quality is monitored based on whether the loan is performing or non-performing, which is typically based on the aging status of the loan and payment activity, unless a specific action, such as bankruptcy, repossession, death or significant delay in payment occurs to raise awareness of a possible credit event.

The following table reflects the loans on nonaccrual status as of December 31, 2020 and 2019, respectively. The balances are presented by class of loan (in thousands): 2020 2019 Real estate loans: Mortgages $ 787 $ 903 Home Equity 25 59 Commercial 4,529 5,080 Agricultural 3,133 2,578 Consumer - 6 Other commercial loans 1,284 1,837 Other agricultural loans 974 1,073 $ 10,732 $ 11,536 Interest income on loans would have increased by approximately $756,000, $647,000 and $961,000 during 2020, 2019 and 2018, respectively, if these loans had performed in accordance with their terms. Loan Modifications Related to COVID-19 The Company has elected to follow the loan modification guidance under Section 4013 of the CARES Act with regard to COVID-19 modifications made between March 1, 2020 and the earlier of either December 31, 2020 or the 60th day after the end of the COVID-19 national emergency. Under section 4013 of the CARES Act, loans less than 30 days past due as of December 31, 2019 will be considered current for COVID-19 modifications. A financial institution can then suspend the requirements under GAAP for loan modifications related to COVID-19 that would otherwise be categorized as a TDR, and suspend any determination of a loan modified as a result of COVID-19 as being a TDR, including the requirement to determine impairment for accounting purposes. Similarly, the Financial Accounting Standards Board has confirmed that short-term modifications made on a good-faith basis in response to COVID-19 to loan customers who were current prior to any relief are not TDRs. A modification of six months or less is considered to be a short-term loan modification. In response to the COVID-19 pandemic, the Company has prudently executed loan modifications for existing loan customers, which includes deferrals of interest and in certain cases deferrals of principal and interest. In addition, the risk-rating on COVID-19 modified loans did not change, and these loans will not be considered past due until after the deferral period is over and scheduled payments resume. The credit quality of these loans will be reevaluated after the deferral period ends. The following table presents information regarding loans which were subject to a loan modification related to COVID-19, with balances as of the date of modification and December 31, 2020, as well as the balance by modification type as of December 31, 2020.

Management strives to identify borrowers in financial difficulty early and work with them to modify more affordable terms before their loan reaches nonaccrual status. These modified terms may include rate reductions, principal forgiveness, payment forbearance and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of the collateral. In cases where borrowers are granted new terms that provide for a reduction of either interest or principal, management measures any impairment on the restructuring by calculating the present value of the revised loan terms and comparing this balance to the Company’s investment in the loan prior to the restructuring. As these loans are individually evaluated, they are excluded from pooled portfolios when calculating the allowance for loan and lease losses and a separate allocation within the allowance for loan and lease losses is provided. Management continually evaluates loans that are considered TDRs, including payment history under the modified loan terms, the borrower’s ability to continue to repay the loan based on continued evaluation of their operating results and cash flows from operations. Based on this evaluation management would no longer consider a loan to be a TDR when the relevant facts support such a conclusion. As of December 31, 2020, 2019 and 2018, included within the allowance for loan losses are reserves of $257,000, $345,000 and $255,000, respectively, that are associated with loans modified as TDRs. Loan modifications that are considered TDRs completed during the years ended December 31, 2020, 2019 and 2018 were as follows (dollars in thousands): Number of contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment 2020 Interest Modification Term Modification Interest Modification Term Modification Interest Modification Term Modification Real estate loans: Mortgages - 1 $ - $ 2 $ - $ 2 Home Equity - - - - - - Commercial - 10 - 2,456 - 2,456 Agricultural - 2 - 494 - 494 Consumer - 1 - 3 3 Other commercial loans - 2 - 1,094 1,094 Other agricultural loans - 1 - 19 - 19 Total - 17 $ - $ 4,068 $ - $ 4,068 Number of contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment 2019 Interest Modification Term Modification Interest Modification Term Modification Interest Modification Term Modification Real estate loans: Mortgages - 1 $ - $ 4 $ - $ 4 Home Equity - 1 - 40 - 40 Commercial - 6 - 918 - 918 Agricultural - 5 - 1,731 - 1,731 Consumer - 1 - 3 3 Other commercial loans - 1 - 55 55 Other agricultural loans - 5 - 1,054 - 1,054 Total - 20 $ - $ 3,805 $ - $ 3,805 Number of contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment 2018 Interest Modification Term Modification Interest Modification Term Modification Interest Modification Term Modification Real estate loans: Mortgages - 1 $ - $ 7 $ - $ 7 Home Equity - 1 - 1 - 1 Commercial - 2 - 683 - 683 Agricultural - 5 - 3,209 - 3,209 Other agricultural loans - 4 - 176 - 176 Total - 13 $ - $ 4,076 $ - $ 4,076 Recidivism, or the borrower defaulting on its obligation pursuant to a modified loan, results in the loan once again becoming a non-accrual loan. Recidivism occurs at a notably higher rate than do defaults on new origination loans, so modified loans present a higher risk of loss than do new origination loans. The following table presents the recorded investment in loans that were modified as TDRs during each 12-month period prior to the current reporting periods, which begin January 1, 2020, 2019 and 2018, respectively, and that subsequently defaulted during these reporting periods (dollars in thousands): December 31, 2020 December 31, 2019 December 31, 2018 Number of contracts Recorded investment Number of contracts Recorded investment Number of contracts Recorded investment Real estate loans: Commercial 1 $ 110 - $ - 2 $ 683 Agricultural - - 1 1,439 2 1,325 Other agricultural loans - - 3 137 1 161 Total recidivism 1 $ 110 4 $ 1,576 5 $ 2,169 Foreclosed Assets Held For Sale Foreclosed assets acquired in settlement of loans are carried at fair value, less estimated costs to sell, and are included in other assets on the Consolidated Balance Sheet. As of December 31, 2020 and 2019 included with other assets are $1,836,000, and $3,404,000, respectively, of foreclosed assets. As of December 31, 2020, included within the foreclosed assets is $359,000 of consumer residential mortgages that were foreclosed on or received via a deed in lieu transaction prior to the period end. As of December 31, 2020, the Company has initiated formal foreclosure proceedings on $303,000 of consumer residential mortgages, which have not yet been transferred into foreclosed assets.

FEDERAL HOME LOAN BANK (FHLB) STOCK	8. FEDERAL HOME LOAN BANK (FHLB) STOCK As a member of the FHLB of Pittsburgh, the Bank is required to maintain a minimum investment in stock of the FHLB that varies with the level of advances outstanding with the FHLB. As of December 31, 2020 and 2019, the Bank held $4,593,000 and $6,087,000, respectively, of FHLB stock. The stock does not have a readily determinable fair value and as such is classified as restricted stock, carried at cost and evaluated by management. The stock’s value is determined by the ultimate recoverability of the par value rather than by recognizing temporary declines. The determination of whether the par value will ultimately be recovered is influenced by criteria such as the following: (a) A significant decline in net assets of the FHLB as compared to the capital stock amount and the length of time this situation has persisted (b) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance (c) the impact of legislative and regulatory changes on the customer base of the FHLB and (d) the liquidity position of the FHLB. Management evaluated the stock and concluded that the stock was not impaired for the periods presented herein. Management considered that the FHLB’s regulatory capital ratios are strong, liquidity appears adequate, new shares of FHLB stock continue to exchange hands at the $100 par value and the FHLB has repurchased shares of excess capital stock from its members and has paid a quarterly cash dividend.

EMPLOYEE BENEFIT PLANS

EMPLOYEE BENEFIT PLANS [Abstract]
EMPLOYEE BENEFIT PLANS	11. EMPLOYEE BENEFIT PLANS Noncontributory Defined Benefit Pension Plan The Bank sponsors a trusteed, noncontributory defined benefit pension plan covering substantially all employees and officers hired prior to January 1, 2007. The Bank also assumed the noncontributory defined benefit pension plan of FNB when it was acquired during 2015. The FNB plan was frozen prior to the acquisition and therefore, no additional benefits will accrue for employees covered under that plan. The Board of Directors in 2018 voted to terminate the plan acquired as part of the FNB acquisition with final settlement occurring in the fourth quarter of 2019. These two plans are collectively referred to herein as “the Plans”. The pension plans call for benefits to be paid to eligible employees at retirement based primarily upon years of service with the Bank and compensation rates during employment. Upon retirement or other termination of employment, employees can elect either an annuity benefit or a lump sum distribution of vested benefits in the pension plan. The Bank’s funding policy is to make annual contributions, if needed, based upon the funding formula developed by the pension plans’ actuary. The Bank did not make any contributions to the pension plans in 2020, 2019 and 2018. In lieu of the pension plan, employees with a hire date of January 1, 2007 or later are eligible to receive, after meeting length of service requirements, an annual discretionary 401(k) plan contribution from the Bank equal to a percentage of an employee’s base compensation. The contribution amount is placed in a separate account within the 401(k) plan and is subject to a vesting requirement. Contributions by the Company totaled $212,000, $200,000 and $151,000 for 2020, 2019 and 2018, respectively. The following table sets forth the obligation and funded status of the Plans as of December 31 (in thousands): 2020 2019 Change in benefit obligation Benefit obligation at beginning of year $ 13,027 $ 17,895 Service cost 330 289 Interest cost 332 588 Actuarial (Gain) / Loss 1,810 1,706 Settlement gain (34 ) (259 ) Benefits paid (1,445 ) (7,192 ) Benefit obligation at end of year 14,020 13,027 Change in plan assets Fair value of plan assets at beginning of year 13,277 18,212 Actual return (loss) on plan assets 1,415 2,394 Employer contribution - - Plan expenses - (37 ) Transfer to 401(k) plan - (100 ) Benefits paid (1,445 ) (7,192 ) Fair value of plan assets at end of year 13,247 13,277 Funded status $ (773 ) $ 250 Amounts not yet recognized as a component of net periodic pension cost as of December 31 (in thousands): Amounts recognized in accumulated other comprehensive loss consists of: 2020 2019 Net loss $ 4,383 $ 3,727 Prior service cost - (32 ) Total $ 4,383 $ 3,695 The accumulated benefit obligation for the defined benefit pension plan was $14,020,000 and $13,027,000 at December 31, 2020 and 2019, respectively. The components of net periodic benefit costs for the years ended December 31 are as follows (in thousands): 2020 2019 2018 Affected line item on the Consolidated Statement of Income Service cost $ 330 $ 289 $ 359 Salary and Employee Benefits Interest cost 332 588 652 Other Expenses Return on plan assets (862 ) (924 ) (1,126 ) Other Expenses Settlement loss (gain) 302 (259 ) - Other Expenses Net amortization and deferral 233 272 186 Other Expenses Net periodic benefit cost $ 335 $ (34 ) $ 71 The estimated net loss that will be amortized from accumulated other comprehensive loss into the net periodic benefit cost (income) in 2021 is $364,000. The weighted-average assumptions used to determine benefit obligations at December 31, 2020 and 2019 is summarized in the following table. Due to the decision to terminate the pension plan acquired as part of the FNB acquisition, the discount rate for the plans will be separated for the 2020 and 2019 disclosures. The change in the discount rate is the primary driver of the actuarial loss that occurred in 2020 of $1,810,000. 2020 2019 Discount rate FCCB Plan 2.00 % 2.75 % Discount rate FNB Plan 0.00 % 3.33 % Rate of compensation increase 3.00 % 3.00 % The weighted-average assumptions used to determine net periodic benefit cost (income) for the year ended December 31. Due to the decision to terminate the pension plan acquired as part of the FNB acquisition, the discount rate for the plans will be separated for 2019. The rate for 2018 represents a combined rate of the plans: 2020 2019 2018 Discount rate FCCB Plan 2.75 % 4.00 % 3.35 % Discount rate FNB Plan NA 3.49 % 3.35 % Expected long-term return on plan assets FCCB plan 7.00 % 7.00 % 7.00 % Expected long-term return on plan assets FNB plan NA NA 3.00 % Rate of compensation increase 3.00 % 3.00 % 3.00 % The long-term rate of return on plan assets gives consideration to returns currently being earned on plan assets as well as future rates expected to be earned. The investment objective is to maximize total return consistent with the interests of the participants and beneficiaries, and prudent investment management. The allocation of the pension plan assets is determined on the basis of sound economic principles and is continually reviewed in light of changes in market conditions. Asset allocation favors equity securities, with a target allocation of 50-70%. The target allocation for debt securities is 30-50%. At December 31, 2020, the pension plan had a sufficient cash and money market position in order to re-allocate the equity portfolio for diversification purposes and reduce risk in the total portfolio. The following table sets forth by level, within the fair value hierarchy as defined in footnote 18, the Plan’s assets at fair value as of December 31, 2020 and 2019 (dollars in thousands): 2020 Level I Level II Level III Total Allocation Assets Cash and cash equivalents $ 456 $ - $ - $ 456 3.4 % Equity Securities 5,709 - - 5,709 43.1 % Mutual Funds and ETF's 4,410 - - 4,410 33.3 % Corporate Bonds - 2,672 - 2,672 20.2 % Total $ 10,575 $ 2,672 $ - $ 13,247 100.0 % 2019 Level I Level II Level III Total Allocation Assets Cash and cash equivalents $ 924 $ - $ - $ 924 7.0 % Equity Securities 5,084 - - 5,084 38.3 % Mutual Funds and ETF's 4,175 - - 4,175 31.4 % Corporate Bonds - 3,094 - 3,094 23.3 % Total $ 10,183 $ 3,094 $ - $ 13,277 100.0 % Equity securities include the Company’s common stock in the amounts of $627,000 (4.7% of total plan assets) and $681,000 (5.1% of total plan assets) at December 31, 2020 and 2019, respectively. The Bank does not expect to make a contribution to its pension plan in 2021. Expected future benefit payments that the Bank estimates from its pension plan are as follows (in thousands): 2021 $ 1,048 2022 570 2023 639 2024 809 2025 1,199 2026 - 2030 5,146 Defined Contribution Plan The Company sponsors a voluntary 401(k) savings plan which eligible employees can elect to contribute up to the maximum amount allowable not to exceed the limits of IRS Code Sections 401(k). Under the plan, the Company also makes required contributions on behalf of the eligible employees. The Company’s contributions vest immediately. Contributions by the Company totaled $518,000, $446,000 and $433,000 for 2020, 2019 and 2018, respectively. Directors’ Deferred Compensation Plan The Company’s directors may elect to defer all or portions of their fees until their retirement or termination from service. Amounts deferred under the deferred compensation plan earn interest based upon the highest current rate offered to certificate of deposit customers. Amounts deferred under the deferred compensation plan are not guaranteed and represent a general liability of the Company. As of December 31, 2020 and 2019, an obligation of $632,000 and $865,000, respectively, was included in other liabilities for this plan in the Consolidated Balance Sheet. Amounts included in interest expense on the deferred amounts totaled $8,000, $19,000 and $22,000 for the years ended December 31, 2020, 2019 and 2018, respectively. Restricted Stock Plan The Company maintains a Restricted Stock Plan (the Plan) whereby employees and non-employee corporate directors are eligible to receive awards of restricted stock based upon performance related requirements. Awards granted under the Plan are in the form of the Company’s common stock and maybe subject to certain vesting requirements including in the case of employees, continuous employment or service with the Company. In April 2016, the Company’s stockholder authorized a total of 150,000 shares of the Company’s common stock to be made available under the Plan. As of December 31, 2020, 124,051 shares remain available to be issued under the Plan. The Plan assists the Company in attracting, retaining and motivating employees to make substantial contributions to the success of the Company and to increase the emphasis on the use of equity as a key component of compensation. The following table details the vesting, awarding and forfeiting of unearned restricted shares during 2020: 2020 Shares Weighted Average Market Price Outstanding, beginning of year 10,877 $ 60.11 Granted 5,160 50.89 Forfeited (337 ) 57.43 Vested (5,498 ) 59.37 Outstanding, end of year 10,202 $ 55.93 Compensation cost related to restricted stock is recognized based on the market price of the stock at the grant date over the vesting period. Compensation expense related to restricted stock was $333,000, $299,000 and $256,000 for the years ended December 31, 2020, 2019 and 2018, respectively. The per share weighted-average grant-date fair value of restricted shares granted during 2020, 2019 and 2018 was $50.89, $60.02 and $62.74, respectively. At December 31, 2020, the total compensation cost related to nonvested awards that has not yet been recognized was $571,000, which is expected to be recognized over the next 3 years. Supplemental Executive Retirement Plan The Company maintains a non-qualified supplemental executive retirement plan (“SERP”) for certain executives to compensate those executive participants in the Company’s noncontributory defined benefit pension plan whose benefits are limited by compensation limitations under current tax law. At December 31, 2020 and 2019, an obligation of $2,077,000 and $2,002,000, respectively, for the SERP was included in other liabilities in the Consolidated Balance Sheet. Expenses related to the SERP totaled $107,000, $251,000 and $180,000 for the years ended December 31, 2020, 2019 and 2018, respectively. Benefit payments for 2020 were $32,000. There were no benefit payments in 2019 or 2018. Deferred Compensation Plan The Company in 2018 initiated a non-qualified executive deferred compensation plan for eligible employees designated by the Board of Directors. At December 31, 2020 and 2019, an obligation of $631,000 and $438,000, respectively, was included in other liabilities for the deferred compensation plan in the Consolidated Balance Sheet. Expenses related to the deferred compensation plan totaled $230,000, $343,000, and $95,000 for the years ended December 31, 2020, 2019 and 2018, respectively. There were no benefit payments in 2020, 2019 or 2018. Salary Continuation Plan The Company maintains a salary continuation plan for certain employees acquired through the acquisition of the FNB. At December 31, 2020 and 2019 an obligation of $673,000 and $690,000, respectively, was included in other liabilities for this plan in the Consolidated Balance Sheet. Expenses related to the salary continuation plan totaled $51,000, $52,000 and $53,000 for the years ended December 31, 2020, 2019 and 2018, respectively. Continuation of Life Insurance Plan The Company, as part of the acquisition of FNB, has promised a continuation of life insurance coverage to certain persons post-retirement. GAAP requires the recording of post-retirement costs and a liability equal to the present value of the cost of post-retirement insurance during the person’s term of service. The estimated present value of future benefits to be paid totaled $687,000 and $684,000 at December 31, 2020 and 2019, respectively, which is included in other liabilities in the Consolidated Balance Sheet. Expenses for the plan totaled $2,600, $36,000 and $70,000 for the years ended December 31, 2020, 2019 and 2018, respectively.

The total provision for income taxes is different from that computed at the statutory rates due to the following items (dollars in thousands): Year Ended December 31, 2020 2019 2018 Provision at statutory rates on pre-tax income $ 6,377 $ 4,895 $ 4,502 Effect of tax-exempt income (936 ) (920 ) (955 ) Low income housing tax credits (141 ) (141 ) (141 ) Bank owned life insurance (146 ) (131 ) (131 ) Nondeductible interest 44 52 41 Nondeductible merger and acquisition expenses 32 38 - Other items 33 27 87 Provision for income taxes $ 5,263 $ 3,820 $ 3,403 Statutory tax rates 21 % 21 % 21 % Effective tax rates 17.3 % 16.4 % 15.9 % The Company prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Benefits from tax positions should be recognized in the financial statements only when it is more likely than not that the tax position will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should be derecognized in the first subsequent financial reporting period in which that threshold is no longer met. There is currently no liability for uncertain tax positions and no known unrecognized tax benefits. With limited exception, the Company’s federal and state income tax returns for taxable years through 2016 have been closed for purposes of examination by the federal and state taxing authorities. Investments in Qualified Affordable Housing Projects As of December 31, 2020 and 2019, the Company was invested in four partnerships that provide affordable housing. The balance of the investments, which is included within other assets in the Consolidated Balance Sheet, was $216,000 and $325,000 as of December 31, 2020 and 2019, respectively. Investments purchased prior to January 1, 2015, are accounted for utilizing the effective yield method. As of December 31, 2020, the Company has $282,000 of tax credits remaining that will be recognized over two years. Tax credits of $141,000 were recognized as a reduction of tax expense during 2020, 2019 and 2018. Included within other expenses on the Consolidated Statement of Income was $108,000 of amortization of the investments in qualified affordable housing projects for 2020, 2019 and 2018, respectively.

REGULATORY MATTERS [Abstract]
REGULATORY MATTERS	15. REGULATORY MATTERS Dividend Restrictions: The approval of the Federal Reserve Board (FRB) is required for the Bank to pay dividends to the Company if the total of all dividends declared in any calendar year exceeds the Bank’s net income (as defined) for that year combined with its retained net income for the preceding two Loans: The Bank is subject to regulatory restrictions which limit its ability to loan funds to the Company. At December 31, 2020, the Bank’s regulatory lending limit amounted to approximately $27,610,000. Regulatory Capital Requirements: Federal regulations require the Bank to maintain minimum amounts of capital. Specifically, the Bank is required to maintain certain minimum dollar amounts and ratios of Total, Tier I and Common Equity Tier I capital to risk-weighted assets and of Tier I capital to average total assets. In addition to the capital requirements, the Federal Deposit Insurance Corporation Improvement Act (FDICIA) established five capital categories ranging from “well capitalized” to “critically under-capitalized.” Should any institution fail to meet the requirements to be considered “adequately capitalized”, it would become subject to a series of increasingly restrictive regulatory actions. As permitted by applicable federal regulation, the Bank has opted to use the community bank leverage ratio (the “CBLR”) framework for determining its capital adequacy. Under the CBLR framework a qualifying community bank is considered well-capitalized if its leverage ratio (Tier 1 capital divided by average total consolidated assets) exceeds 9%. Following the passage of the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act in response to the COVID-19 pandemic, the federal banking regulators revised the CBLR framework as follows: (i) beginning in the second quarter of 2020, a qualifying community bank need only have a leverage ratio of at least 8%, subject to the other qualifying requirements, and (ii) if a qualifying community bank’s leverage ratio falls below 8%, then it will have two calendar quarters to maintain a leverage ratio of 7% or greater. These revisions under the CARES Act are effective April 23, 2020 and will terminate upon the earlier of the termination of the national emergency related to COVID-19 or December 31, 2020. Following such termination there is a grace period for returning to the 9% CBLR threshold. The CBLR will be set at 8% for the remainder of 2020, 8.5% for 2021, and 9% thereafter. The grace period is also adjusted to account for the graduating increase. As a result, in 2020 and 2021, a qualifying community bank utilizing the grace period must maintain a CBLR of at least 7% and 7.5%, respectively. Thereafter, a qualifying community bank utilizing the grace period must maintain a CBLR of at least 8%. If a qualifying community bank fails to maintain the applicable minimum CBLR during the grace period, or if it is unable to restore compliance with the CBLR within the grace period, then it will revert to the Basel III capital framework and the normal Prompt Corrective Action capital categories will apply. At December 31, 2020, the Bank was considered “well-capitalized” under the CBLR framework, with a leverage ratio of 8.75%. The Bank’s computed risk‑based capital ratios are as follows as of December 31, 2019 (dollars in thousands): Actual For Capital Adequacy Purposes To Be Well Capitalized Under Prompt Corrective Action Provisions 2019 Amount Ratio Amount Ratio Amount Ratio Total Capital (to Risk Weighted Assets): Company $ 154,708 14.04 % $ 88,166 8.00 % $ 110,208 10.00 % Bank $ 146,925 13.34 % $ 88,102 8.00 % $ 110,128 10.00 % Tier 1 Capital (to Risk Weighted Assets): Company $ 140,929 12.79 % $ 66,125 6.00 % $ 88,166 8.00 % Bank $ 133,156 12.09 % $ 66,077 6.00 % $ 88,102 8.00 % Common Equity Tier 1 Capital (to Risk Weighted Assets): Company $ 133,429 12.11 % $ 49,593 4.50 % $ 71,635 6.50 % Bank $ 133,156 12.09 % $ 49,557 4.50 % $ 71,583 6.50 % Tier 1 Capital (to Average Assets): Company $ 140,929 9.77 % $ 57,705 4.00 % $ 72,132 5.00 % Bank $ 133,156 9.23 % $ 57,681 4.00 % $ 72,101 5.00 %

COMMITMENTS, CONTINGENT LIABILITIES, RISKS AND UNCERTAINTIES	16. COMMITMENTS, CONTINGENT LIABILITIES, RISKS AND UNCERTAINTIES The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing 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 and interest rate or liquidity risk in excess of the amount recognized in the consolidated balance sheet. Credit Extension Commitments The Company’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 Company 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, 2020 and 2019, are as follows (in thousands): 2020 2019 Commitments to extend credit $ 274,327 $ 211,530 Standby letters of credit 21,978 17,857 $ 296,305 $ 229,387 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 Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained if deemed necessary by the Company on extension of credit is based on management’s credit assessment of the counter party. Standby letters of credit are conditional commitments issued by the Company to guarantee a financial agreement between a customer and a third party. Performance letters of credit represent conditional commitments issued by the Bank to guarantee the performance of a customer to a third party. These instruments are issued primarily to support bid or performance related contracts. The coverage period for these instruments is typically a one-year period with an annual renewal option subject to prior approval by management. Fees earned from the issuance of these letters are recognized during the coverage period. For secured letters of credit, the collateral is typically Bank deposit instruments or customer business assets. The Company also offers limited overdraft protection as a non-contractual courtesy which is available to demand deposit accounts in good standing for business, personal or household use. The non-contractual amount of financial instruments with off-balance sheet risk at December 31, 2020 was $12,210,000. The Company reserves the right to discontinue this service without prior notice. Legal and Regulatory Proceedings In the ordinary course of business, the Company is subject to legal proceedings, including claims, litigation, investigations and administrative proceedings, all of which are considered incidental to the normal conduct of business. Litigation may relate to lending, deposit and other customer relationships, vendor and contractual issues, employee matters, intellectual property matters, personal injuries and torts, regulatory and legal compliance, and other matters. The Company believes it has substantial defenses to the claims asserted against it in its currently outstanding legal proceedings and, with respect to such legal proceedings, intends to defend itself vigorously. The Company assesses its liabilities and contingencies in connection with outstanding legal proceedings utilizing the latest information available. Where it is probable that the Company will incur a loss and the amount of the loss can be reasonably estimated, the Company records a liability in its consolidated financial statements. These legal reserves may be increased or decreased to reflect any relevant developments. Where a loss is not probable or the amount of a probable loss is not reasonably estimable, the Company does not accrue legal reserves. Additionally, for those matters where a loss is reasonably possible and the amount of loss is reasonably estimable, the Company estimates the amount of losses that it could incur beyond the accrued legal reserves. Under U.S. GAAP, an event is “reasonably possible” if “the chance of the future event or events occurring is more than remote but less than likely” and an event is “remote" if “the chance of the future event or events occurring is slight.” While the outcome of legal proceedings and the timing of the ultimate resolution are inherently difficult to predict, based on information currently available, advice of counsel and available insurance coverage, the Company believes that it has established adequate legal reserves. Further, based upon available information, the Company is of the opinion that these legal proceedings, individually or in the aggregate, will not have a material adverse effect on the Company’s financial condition or results of operations. However, in the event of unexpected future developments, it is reasonably possible that an adverse outcome in any of the matters discussed above could be material to the Company’s business, consolidated financial position, results of operations or cash flows for any particular reporting period of occurrence. Paycheck Protection Program (PPP) Since the opening of the PPP, several larger banks have been subject to litigation regarding the process and procedures that such banks used in processing applications for the PPP. The Company may be exposed to the risk of similar litigation, from both customers and non-customers that approached the bank regarding PPP loans, regarding the process and procedures used in processing applications for the PPP. If any such litigation is filed against and is not resolved in a manner favorable to the Company, it may result in significant financial liability or adversely affect reputation. In addition, litigation can be costly, regardless of outcome. Any financial liability, litigation costs or reputational damage caused by PPP-related litigation could have a material adverse impact on our business, financial condition and results of operations. The Company also has credit risk on PPP loans if a determination is made by the SBA that there is a deficiency in the manner in which the loan was originated, funded, or serviced by, such as an issue with the eligibility of a borrower to receive a PPP loan, which may or may not be related to the ambiguity in the laws, rules and guidance regarding the operation of the PPP. In the event of a loss resulting from a default on a PPP loan and a determination by the SBA that there was a deficiency in the manner in which the PPP loan was originated, funded, or serviced by the Company , the SBA may deny its liability under the guaranty, reduce the amount of the guaranty, or, if it has already paid under the guaranty, seek recovery of any loss related to the deficiency from the Company.

DERIVATIVE FINANCIAL INSTRUMENTS [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	17. DERIVATIVE FINANCIAL INSTRUMENTS The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities and through the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to certain variable rate borrowings. Cash Flow Hedges of Interest Rate Risk The Company’s objectives in using interest rate derivatives are to add stability to interest income and expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company has entered into interest rate swaps as part of its interest rate risk management strategy. These interest rate swaps are designated as cash flow hedges and involve the receipt of variable rate amounts from a counterparty in exchange for the Company making fixed interest payments. As of December 31, 2020, the Company had six interest rate swaps with a notional of $50.5 million associated with the Company’s cash outflows associated with various floating-rate amounts. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is initially reported in other comprehensive income (outside of earnings), net of tax, and subsequently reclassified to earnings when the hedged transaction affects earnings, and the ineffective portion of changes in the fair value of the derivative is recognized directly in earnings. The Company assesses the effectiveness of each hedging relationship by comparing the changes in cash flows of the derivative hedging instrument with the changes in cash flows of the designated hedged transactions. The Company did not recognize any hedge ineffectiveness in earnings during the period ended December 31, 2020. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s variable-rate liabilities. During the next twelve months, the Company estimates that $0 will be reclassified as an increase in interest expense. Customer Swaps The Company also enters into derivative contracts, which consist of interest rate swaps, to facilitate the needs of customers desiring to manage interest rate risk. These swaps are not designated as accounting hedges under ASC 815, Derivatives and Hedging. In order to economically hedge the interest rate risk associated with offering this product, the Company simultaneously enters into derivative contracts with third parties to offset the customer contracts, such that the Company minimizes its net risk exposure resulting from such transactions. The derivative contracts are structured such that the notional amounts decrease over time to generally match the expected amortization of the underlying loans. These derivatives are not speculative and arise from a service provided to customers. The Company utilizes a loan hedging program to accommodate clients preferring a fixed rate loan. The loan documents include an addendum with a zero premium collar. The zero premium collar is a cap and floor at the same interest rate, resulting in a fixed rate to the borrower. To hedge this embedded option, the Company enters into a dealer facing trade exactly mirroring the terms of the loan addendum. At December 31, 2020, the Company had interest rate swaps related to this program with an aggregate notional amount of $64.0 million. Counterparty Credit Risk As a result of its derivative contracts, the Company is exposed to credit risk. Specifically, approved counterparties and exposure limits are defined. On at least an annual basis, the customer derivative contracts and related counterparties are evaluated for credit risk with an adjustment made to the contracts fair value. In accordance with the interest rate agreements with derivative dealers, the Company maybe required to post margin to these counterparties. At December 31, 2020, the Company has required collateral with certain of its derivative counterparties in the amount of $6.5 million and was not holding collateral of any derivative counterparties. The following table reflects the estimated fair value positions of derivative contracts as of December 31, 2020: Derivatives designated as hedging instruments under ASC 815 (in thousands): Third party interest rate swaps Balance Sheet Location Notional Amount Interest rate Paid Interest rate Received Fair Value Maturing in 2025 Other liabilities $ 15,000 Fixed - 0.57% 3-Month Libor $ (143 ) Maturing in 2027 Other liabilities 10,000 Fixed - 0.65% 3-Month Libor (50 ) Maturing in 2027 Other liabilities 7,500 Fixed - 3.57% 3-Month Libor + 280 (87 ) Maturing in 2027 Other liabilities 6,000 Fixed - 0.61% 3-Month Libor 24 Maturing in 2029 Other liabilities 6,000 Fixed - 0.72% 3-Month Libor 74 Maturing in 2032 Other liabilities 6,000 Fixed - 0.82% 3-Month Libor 171 $ 50,500 $ (11 ) Derivatives not designated as hedging instruments under ASC 815 (in thousands): Interest Rate Products Balance Sheet Location Notional Amount Fair Value Zero Premium Collar Other assets $ 64,013 $ 1,111 Dealer Offset to Zero Premium Collar Other liabilities $ 64,013 $ (1,111 )

LEASES [Abstract]
LEASES	18. LEASES A lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. On January 1, 2019, the Company adopted ASU No. 2016-02 “Leases” (Topic 842) Lessee Accounting Substantially all of the leases in which the Company is the lessee are comprised of real estate property for branches with terms extending through 2029. All of the Company’s leases are classified as operating leases, and therefore, were previously not recognized on the Company’s Consolidated Balance Sheet. With the adoption of Topic 842, operating lease agreements are required to be recognized on the consolidated statements of condition as right-of-use (“ROU”) assets and corresponding lease liabilities. The following table represents the Consolidated Balance Sheet classification of the Company’s ROU assets and lease liabilities (in thousands) . The Company elected not to include short-term leases (i.e., leases with initial terms of twelve months or less), on the Consolidated Balance Sheet. Balance at December 31, Lease Type 2020 2019 Affected line item on the Consolidated Balance Sheet Right of Use Assets Operating $ 2,286 $ 1,163 Other Assets Lease Liabilities: Operating $ 2,295 $ 1,163 Other Liabilities The calculated amount of the ROU assets and lease liabilities in the table above are impacted by the length of the lease term and the discount rate used to present value the minimum lease payments. The Company’s lease agreements often include one or more options to renew at the Company’s discretion. If at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the ROU asset and lease liability. Regarding the discount rate, Topic 842 requires the use of the rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term. For operating leases existing prior to January 1, 2019, the rate for the remaining lease term as of January 1, 2019 was used. The following table displays the weighted average remaining lease term and the weighted average discount rate for the Company’s operating leases outstanding as of December 31, 2020: Operating Weighted average term (years) 5.57 Weighted average discount rate 1.97 % The following table represents lease costs and other lease information for the years ended December 31, 2020, and 2019, respectively (in thousands). As the Company elected not to separate lease and non-lease components and instead to account for them as a single lease component, the variable lease cost primarily represents variable payments such as common area maintenance and utilities. December 31, Lease Cost 2020 2019 Operating lease cost $ 571 $ 340 Variable lease cost 50 88 Total lease cost $ 621 $ 428 Future minimum payments for operating leases with initial or remaining terms of one year or more as of December 31, 2020 along with a reconciliation to the discounted amount recorded on the December 31, 2020 Consolidated Balance Sheet (in thousands): Undiscounted cash flows due within: Operating 2021 $ 669 2022 491 2023 370 2024 240 2025 169 2026 and thereafter 499 Total undiscounted cash flows 2,438 Impact of present value discount 143 Amount reported on balance sheet $ 2,295

FAIR VALUE OF FINANCIAL INSTRUM

FAIR VALUE OF FINANCIAL INSTRUMENTS [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS	19. FAIR VALUE OF FINANCIAL INSTRUMENTS The Company established a hierarchal disclosure framework associated with the level of pricing observability utilized in measuring assets and liabilities at fair value. The three broad levels defined by this hierarchy are as follows: Level I: Quoted prices are available in active markets for identical assets or liabilities as of the reported date. Level II: Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reported date. The nature of these assets and liabilities include items for which quoted prices are available but traded less frequently, and items that are fair valued using other financial instruments, the parameters of which can be directly observed. Level III: Assets and liabilities that have little to no pricing observability as of the reported date. These items do not have two-way markets and are measured using management’s best estimate of fair value, where the inputs into the determination of fair value require significant management judgment or estimation. A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developed models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality, the Company's creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. Our valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer, which generally coincides with the Company’s monthly and/or quarterly valuation process. Assets and Liabilities Required to be Measured at Fair Value on a Recurring Basis The fair values of equity securities and securities available for sale are determined by quoted prices in active markets, when available, and classified as Level I. If quoted market prices are not available, the fair value is determined by a matrix pricing, which is a mathematical technique, widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities and classified as Level II. The fair values consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. The following tables present the assets reported on the consolidated balance sheet at their fair value on a recurring basis as of December 31, 2020 and 2019 (in thousands) by level within the fair value hierarchy. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. 2020 Level I Level II Level III Total Fair value measurements on a recurring basis: Assets Equity securities $ 1,931 $ - $ - $ 1,931 Available for sale securities: U.S. Agency securities - 81,416 - 81,416 U.S. Treasuries securities 28,043 - - 28,043 Obligations of state and political subdivisions - 102,972 - 102,972 Corporate obligations - 6,509 - 6,509 Mortgage-backed securities in government sponsored entities - 76,249 - 76,249 Other Assets Derivative instruments - 1,111 - 1,111 Liabilities: Derivative instruments - (1,122 ) - (1,122 ) 2019 Level I Level II Level III Total Fair value measurements on a recurring basis: Assets Equity securities $ 701 $ - $ - $ 701 Available for sale securities: U.S. Agency securities - 84,863 - 84,863 U.S. Treasuries securities 27,661 - - 27,661 Obligations of state and political subdivisions - 61,455 - 61,455 Corporate obligations - 3,328 - 3,328 Mortgage-backed securities in government sponsored entities - 63,399 - 63,399 Financial Instruments, Non-Financial Assets and Non-Financial Liabilities Recorded at Fair Value on a Nonrecurring Basis The Company may be required, from time to time, to measure certain financial assets, financial liabilities, non-financial assets and non-financial liabilities at fair value on a nonrecurring basis in accordance with U.S. generally accepted accounting principles. These include assets that are measured at the lower of cost or market value that were recognized at fair value below cost at the end of the period. Certain non-financial assets measured at fair value on a non-recurring basis include foreclosed assets (upon initial recognition or subsequent impairment), non-financial assets and non-financial liabilities measured at fair value in the second step of a goodwill impairment test, and intangible assets and other non-financial long-lived assets measured at fair value for impairment assessment. Non-financial assets measured at fair value on a non-recurring basis during 2020 and 2019 include certain foreclosed assets which, upon initial recognition, were remeasured and reported at fair value through a charge-off to the allowance for possible loan losses and certain foreclosed assets which, subsequent to their initial recognition, were remeasured at fair value through a write-down included in other non-interest expense. Assets measured at fair value on a nonrecurring basis as of December 31, 2020 and 2019 (in thousands) are included in the table below: 2020 Level I Level II Level III Total Impaired Loans $ - $ - $ 3,243 $ 3,243 Other real estate owned - - 1,700 1,700 2019 Level I Level II Level III Total Impaired Loans $ - $ - $ 3,860 $ 3,860 Other real estate owned - - 3,299 3,299 • Impaired Loans - • Other Real Estate Owned – The following table provides a listing of the significant unobservable inputs used in the fair value measurement process for items valued utilizing level III techniques (dollars in thousands). 2020 Fair Value Valuation Technique(s) Unobservable input Range Weighted average Impaired Loans 3,243 Appraised Collateral Values Discount for time since appraisal 0-100% 20.61% Selling costs 5%-10% 9.51% Holding period 6 - 12 months 11.65 months Other real estate owned 1,700 Appraised Collateral Values Discount for time since appraisal 20-31% 28.67% 2019 Fair Value Valuation Technique(s) Unobservable input Range Weighted average Impaired Loans 3,860 Appraised Collateral Values Discount for time since appraisal 0-100% 19.22% Selling costs 5%-10% 9.26% Holding period 6 - 12 months 11.76 months Other real estate owned 3,299 Appraised Collateral Values Discount for time since appraisal 5-43% 16.37% Financial Instruments Not Required to be Measured or Reported at Fair Value The carrying amount and fair value of the Company’s financial instruments that are not required to be measured or reported at fair value on a recurring basis are as follows (in thousands): December 31, 2020 Carrying Amount Fair Value Level I Level II Level III Financial assets: Interest bearing time deposits with other banks $ 13,758 $ 13,758 $ - $ - $ 13,758 Loans held for sale 14,640 14,640 - - 14,640 Net loans 1,389,466 1,404,166 - - 1,404,166 Financial liabilities: Deposits 1,588,858 1,593,738 1,207,666 - 386,075 Borrowed funds 88,838 88,263 - - 88,263 December 31, 2019 Carrying Amount Fair Value Level I Level II Level III Financial assets: Interest bearing time deposits with other banks $ 14,256 $ 14,635 $ - $ - $ 14,635 Loans held for sale 815 815 - - 815 Net loans 1,101,724 1,091,006 - - 1,091,006 Financial liabilities: Deposits 1,211,118 1,211,200 938,387 - 272,813 Borrowed funds 85,117 84,581 - - 84,581 Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions can significantly affect the estimates. Estimated fair values have been determined by the Company using historical data, as generally provided in the Company’s regulatory reports, and an estimation methodology suitable for each category of financial instruments. The carrying amounts for cash and cash equivalents, bank owned life insurance, regulatory stock, accrued interest receivable and payable approximate fair value and are considered Level I measurements.

ACQUISITION OF MIDCOAST COMMUNITY BANCORP, INC [Abstract]
ACQUISITION OF MIDCOAST COMMUNITY BANCORP, INC	22. ACQUISITION OF MIDCOAST COMMUNITY BANCORP, INC. In the third quarter of 2019, the Company announced the signing of a definitive merger agreement to acquire 100% of the outstanding equity interest of MidCoast Community Bancorp, Inc. (“MidCoast”) for $6.50 per share in cash and stock. MidCoast was a Pennsylvania Corporation that conducted its business primarily through, its wholly owned subsidiary MidCoast Community Bank, which operated from a main office in Wilmington, Delaware, and two branches in Wilmington, Delaware, and one branch in Dover, Delaware. The transaction closed on April 17, 2020, with MidCoast Community Bank having been merged into First Citizens Community Bank, with First Citizens Community Bank as the surviving entity. The acquisition established the Company’s presence in the Wilmington and Dover, Delaware markets. Under the terms of the merger agreement, the Company acquired all of the outstanding shares of MidCoast for a total purchase price of approximately $26,843,000. As a result of the acquisition, the Company issued 373,356 common shares and $7.6 million in cash to the former shareholders of MidCoast. The shares were issued with a value of $51.50 per share, which was based on the close price of the Company’s stock on April 17, 2020. The acquired assets and assumed liabilities were measured at estimated fair values. Management made significant estimates and exercised significant judgment in accounting for the acquisition. Management measured loan fair values based on loan file reviews, appraised collateral values, expected cash flows, and historical loss factors of MidCoast. Real estate acquired through foreclosure was primarily valued based on appraised collateral values. The Company also recorded an identifiable intangible asset representing the core deposit base of MidCoast based on management’s evaluation of the cost of such deposits relative to alternative funding sources. Management used significant estimates including the average lives of depository accounts, future interest rate levels, and the cost of servicing various depository products. The business combination resulted in the acquisition of loans with and without evidence of credit quality deterioration. MidCoast’s loans were deemed to have credit impairment at the acquisition date if the Company did not expect to receive all contractually required cash flows due to concerns about credit quality. Such loans were fair valued and the difference between contractually required payments at the acquisition date and cash flows expected to be collected was recorded as a non-accretable difference. At the acquisition date, the Company recorded $4,869,000 of purchased credit-impaired loans. The method of measuring carrying value of purchased loans differs from loans originated by the Company (originated loans), and as such, the Company identifies purchased loans and purchased loans with a credit quality discount and originated loans at amortized cost. MidCoast’s loans without evidence of credit deterioration were fair valued by discounting both expected principal and interest cash flows using an observable discount rate for similar instruments that a market participant would consider in determining fair value. Additionally, consideration was given to management’s best estimates of default rates and pre-payment speeds. The following table summarizes the purchase of MidCoast as of April 17, 2020: (In Thousands, Except Per Share Data) Purchase Price Consideration in Common Stock Citizens Financial Services, Inc. shares issued 373,356 Value assigned to Citizens Financial Services, Inc. common share $ 51.50 Purchase price assigned to MidCoast common shares exchanged for Citizens Financial Services, Inc. $ 19,228 Purchase Price Consideration - Cash for Common Stock Purchase price assigned to MidCoast common shares exchanged for cash 7,615 Total Purchase Price 26,843 Net Assets Acquired: MidCoast Community Bancorp, Inc shareholders’ equity $ 24,330 Adjustments to reflect assets acquired at fair value: Investments Loans Interest rate 1,424 General credit (4,375 ) Specific credit - non-amortizing (2,135 ) Specific credit - amortizing (966 ) Core deposit intangible 157 Owned premises (426 ) Other assets 65 Deferred tax assets 2,217 Adjustments to reflect liabilities acquired at fair value: Time deposits (1,018 ) Borrowings (497 ) Other liabilities (13 ) 18,763 Goodwill resulting from merger $ 8,080 The following condensed statement reflects the amounts recognized as of the acquisition date for each major class of asset acquired and liability assumed: (In Thousands) Total purchase price $ 26,843 Net assets acquired: Cash and cash equivalents $ 8,637 Loans 223,235 Premises and equipment, net 1,787 Accrued interest receivable 586 Bank-owned life insurance 3,766 Intangibles 157 Deferred tax asset 3,402 Other assets 2,878 Time deposits (123,841 ) Deposits other than time deposits (84,985 ) Accrued interest payable (164 ) Borrowings (15,497 ) Other liabilities (1,198 ) 18,763 Goodwill resulting from the MidCoast merger $ 8,080 The Company recorded goodwill and other intangibles associated with the acquisition of MidCoast totaling $8,237,000. Goodwill is not amortized, but is periodically evaluated for impairment. The Company did not recognize any impairment from April 17, 2020 to December 31, 2020. None of the goodwill acquired is expected to be deductible for tax purposes. Identifiable intangibles are amortized to their estimated residual values over the expected useful lives. Such lives are also periodically reassessed to determine if any amortization period adjustments are required. For the period from April 17, 2020 to December 31, 2020, no such adjustments were recorded. The identifiable intangible asset consists of core deposit intangibles which are being amortized on an accelerated basis over the useful life of such assets. The gross carrying amount of the core deposit intangible at December 31, 2020 was $157,000, with $19,000 accumulated amortization, respectively, as of that date. As of December 31, 2020, the current year and estimated future amortization expense for the core deposit intangibles was (in thousands): Core deposit intangibles Amortization for the period 4/17/20 - 12/31/20 $ 19 Estimate for year ending December 31, 2021 27 2022 24 2023 21 2024 18 2025 15 Thereafter 33 Total $ 138 Amounts recognized separately from the acquisition include primarily legal fees, investment banking fees, system conversion costs, severance costs and contract termination costs. These costs were included in merger and acquisition expenses within non-interest expenses on the Consolidated Statement of Income and amounted to approximately $2,179,000 and $466,000 for 2020 and 2019, respectively. Results of operations for MidCoast prior to the acquisition date are not included in the Consolidated Statement of Income for 2020. The following table presents financial information regarding the former MidCoast operations included in our Consolidated Statement of Income from the date of acquisition through December 31, 2020 under the column “Actual from Acquisition Date through December 31, 2020”. In addition, the following table presents unaudited pro forma information as if the acquisition of MidCoast had occurred on January 1, 2019 under the “Pro Forma” columns. The table below has been prepared for comparative purposes only and is not necessarily indicative of the actual results that would have been attained had the acquisition occurred as of the beginning of the periods presented, nor is it indicative of future results.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
Basis of Presentation	Basis of Presentation The financial statements are consolidated to include the accounts of the Company, and its subsidiary CZFS, and its st
Use of Estimates	Use of Estimates In preparing the financial statements, management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses for the period. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change relate to determination of the allowance for loan losses, goodwill, derivatives, pension
Operating Segments	Operating Segments An operating segment is defined as a component of an enterprise that engages in business activities that generates revenue and incurs expense, and the operating results of which are reviewed by the chief operating decision maker in the determination of resource allocation and performance. While the Company’s chief decision makers monitor the revenue streams of the various Company’s products, services and regions, operations are managed and financial performance is evaluated on a Company-wide basis. Consistent with our internal reporting, the Company’s business activities are reported as one segment, which is community banking.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash equivalents include cash on hand, deposits in banks and interest-earning deposits. Interest-earning deposits with original maturities of 90 days or less are considered cash equivalents. Interest bearing time deposits with other banks are not included with cash and cash equivalents as the original maturities were greater than 90 days.
Investment Securities	Investment Securities Investment securities at the time of purchase are classified as one of the three following types: Held-to-Maturity Securities Trading Securities Available-for-Sale Securities This category included debt securities not classified as held-to-maturity or trading securities that will be held for indefinite periods of time. These securities may be sold in response to changes in market interest or prepayment rates, needs for liquidity and changes in the availability of and yield of alternative investments. Such securities are reported at fair value, with unrealized holding gains and losses excluded from earnings and reported as a separate component of stockholders’ equity, net of the estimated income tax effect The amortized cost of investment in debt securities is adjusted for amortization of premiums and accretion of discounts, computed by a method that results in a level yield. Gains and losses on the sale of investment securities are computed on the basis of specific identification of the adjusted cost of each security. Debt securities are periodically reviewed for other-than-temporary impairment. Management considers whether the present value of future cash flows expected to be collected are less than the security’s amortized cost basis (the difference defined as the credit loss), the magnitude and duration of the decline, the reasons underlying the decline and the Company’s intent to sell the security or whether it is more likely than not that the Company would be required to sell the security before its anticipated recovery in market value, to determine whether the loss in value is other than temporary. Once a decline in value is determined to be other than temporary, if the Company does not intend to sell the security, and it is more-likely-than-not that it will not be required to sell the security, before recovery of the security’s amortized cost basis, the charge to earnings is limited to the amount of credit loss. Any remaining difference between fair value and amortized cost (the difference defined as the non-credit portion) is recognized in other comprehensive income, net of applicable taxes. Otherwise, the entire difference between fair value and amortized cost is charged to earnings. The fair value of investments, except certain state and municipal securities, is based on bid prices published in financial newspapers or bid quotations received from securities dealers. The fair value of certain state and municipal securities is not readily available through market sources other than dealer quotations, so fair value is based on quoted market prices of similar instruments, adjusted for differences between the quoted instruments and the instruments being valued. Equity Securities – This category includes common stocks of public companies. Such securities are reported at fair value with unrealized holding gains and losses included in earnings Restricted Stock
Loans Held for Sale	Loans Held for Sale Certain newly originated fixed-rate residential mortgage loans are classified as held for sale, because it is management’s intent to sell these residential mortgage loans. The residential mortgage loans held for sale are carried at the lower of aggregate cost or fair value.
Loans	Loans Interest on all loans is recognized on the accrual basis based upon the principal amount outstanding. The accrual of interest income on loans is discontinued when, in the opinion of management, doubt exists as to the ability to collect such interest. Payments received on non-accrual loans are applied to the outstanding principal balance or recorded as interest income, depending upon our assessment of our ultimate ability to collect principal and interest. Loans are returned to the accrual status when factors indicating doubtful collectability cease to exist. The Company recognizes nonrefundable loan origination fees, SBA fees and certain direct loan origination costs over the life of the related loan as an adjustment of loan yield using the interest method.
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses represents the amount which management estimates is adequate to provide for probable losses inherent in the Company’s loan portfolio. The allowance method is used in providing for loan losses. Accordingly, all loan losses are charged to the allowance and all recoveries are credited to it. The allowance for loan losses is established through a provision for loan losses which is charged to operations. The provision is based upon management’s periodic evaluation of individual loans, the overall risk characteristics of the various portfolio segments, past experience with losses, the impact of economic conditions on borrowers, and other relevant factors. The estimates used in determining the adequacy of the allowance for loan losses are particularly susceptible to significant change in the near term. Impaired loans are other commercial, other agricultural, municipal, agricultural real estate, commercial real estate loans and certain residential mortgages cross collateralized with commercial relationships for which it is probable that the Company will not be able to collect all amounts due according to the contractual terms of the loan agreement. The Company individually evaluates such loans for impairment and does not aggregate loans by major risk classifications. The definition of “impaired loans” is not the same as the definition of “non-accrual loans,” although the two categories overlap. The Company may choose to place a loan on non-accrual status due to payment delinquency or uncertain collectability, while not classifying the loan as impaired if the loan is not a commercial, agricultural, municipal or commercial real estate loan. Factors considered by management in determining impairment include payment status and collateral value. The amount of impairment for these types of impaired loans is determined by the difference between the present value of the expected cash flows related to the loan, using the original interest rate, and its recorded value; or, as a practical expedient in the case of a collateral dependent loan, the difference between the fair value of the collateral and the recorded amount of the loans. Mortgage loans on one to four family properties and all consumer loans are large groups of smaller balance homogeneous loans and are measured for impairment collectively. Loans that experience insignificant payment delays, which is defined as 90 days or less, generally are not classified as impaired. Management determines the significance of payment delays 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 borrower’s prior payment record, and the amount of shortfall in relation to the principal and interest owed. The Company allocates the allowance based on the factors described below, which conform to the Company’s loan classification policy. In reviewing risk within the loan portfolio, management has determined there to be several different risk categories within the loan portfolio. The allowance for loan losses consists of amounts applicable to: (i) residential real estate loans; (ii) commercial real estate (iii) agricultural real estate loans; (iv) construction; (v) consumer loans; (vi) other commercial loans (vii) other agricultural loans and (viii) state and political subdivision loans. Factors considered in this process include general loan terms, collateral, and availability of historical data to support the analysis. Historical loss percentages for each risk category are calculated and used as the basis for calculating allowance allocations. Certain qualitative factors are evaluated to determine additional inherent risks in the loan portfolio, which are not necessarily reflected in the historical loss percentages. These factors are then added to the historical allocation percentage to get the adjusted factor to be applied to non classified loans. The following qualitative factors are analyzed: • Level of and trends in delinquencies, impaired/classified loans • Change in volume and severity of past due loans • Volume of non-accrual loans • Volume and severity of classified, adversely or graded loans • Level of and trends in charge-offs and recoveries • Trends in volume, terms and nature of the loan portfolio • Effects of any changes in risk selection and underwriting standards and any other changes in lending and recovery policies, procedures and practices • Changes in the quality of the Bank’s loan review system • Experience, ability and depth of lending management and other relevant staff • National, state, regional and local economic trends and business conditions • General economic conditions • Unemployment rates • Inflation / CPI • Changes in values of underlying collateral for collateral-dependent loans • Industry conditions including the effects of external factors such as competition, legal, and regulatory requirements on the level of estimated credit losses. • Existence and effect of any credit concentrations, and changes in the level of such concentrations • Any change in the level of board oversight The Company analyzes its loan portfolio each quarter to determine the appropriateness of its allowance for loan losses.
Loan Charge-off Policies	Loan Charge-off Policies Consumer loans are generally fully or partially charged down to the fair value of collateral securing the asset when the loan is 180 days past due for open-end loans or 120 days past due for closed-end loans unless the loan is well secured and in the process of collection. All other loans are generally charged down to the net realizable value when the loan is 90 days past due.
Troubled Debt Restructurings	Troubled Debt Restructurings In situations where, for economic or legal reasons related to a borrower's financial difficulties, management may grant a concession for other than an insignificant period of time to the borrower that would not otherwise be considered, the related loan is classified as a Troubled Debt Restructuring (TDR). Management strives to identify borrowers in financial difficulty early and work with them to modify more affordable terms before their loan reaches nonaccrual status. These modified terms may include rate reductions, principal forgiveness, payment forbearance and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of the collateral. In cases where borrowers are granted new terms that provide for a reduction of either interest or principal, management measures any impairment on the restructuring as noted above for impaired loans. In addition to the allowance for the pooled portfolios, management has developed a separate allowance for loans that are identified as impaired through a TDR. TDRs are excluded from pooled loss forecasts and a separate reserve is provided under the accounting guidance for loan impairment.
Purchased Credit Impaired Loans	Purchased Credit Impaired Loans The Company purchased loans in connection with its acquisitions of FNB in 2015, the State College branch in 2017 and MidCoast in 2020, some Such PCI loans are accounted for individually, and the Company estimates the amount and timing of expected cash flows for each loan. The expected cash flows in excess of the amount paid is recorded as interest income over the remaining life of the loan (accretable yield). The excess of the loan’s contractual principal and interest over expected cash flows is not amortized over the remaining life of the loan (nonaccretable difference). For loans purchased that did not show evidence of credit deterioration, the difference between the fair value of the loan at the acquisition date and the loan’s face value is being amortized as a yield adjustment over the estimated remaining life of the loan using the effective interest method.
Foreclosed Assets Held For Sale	Foreclosed Assets Held For Sale Foreclosed assets acquired in settlement of loans are carried at fair value, less estimated costs to sell. Prior to foreclosure, as the value of the underlying loan is written down to fair market value of the real estate or other assets to be acquired by a charge to the allowance for loan losses, if necessary. Any subsequent write-downs are charged against operating expenses. Operating expenses of such properties, net of related income and losses on disposition, are included in other expenses and gains and losses are included in other non-interest income or other non-interest expense.
Premises and Equipment	Premises and Equipment Land is carried at cost. Premises and equipment are stated at cost, less accumulated depreciation. Depreciation expense is computed on straight line and accelerated methods over the estimated useful lives of the assets, which range from 3 to 15 years for furniture, fixtures and equipment and 5 to 40 years for building premises. Repair and maintenance expenditures which extend the useful life of an asset are capitalized and other repair expenditures are expensed as incurred. When premises or equipment are retired or sold, the remaining cost and accumulated depreciation are removed from the accounts and any gain or loss is credited to income or charged to expense, respectively. The Company has operating leases for several branch locations. Generally, the underlying lease agreements do not contain any material residual value guarantees or material restrictive covenants. The Company may also lease certain office equipment under operating leases. Many of our leases include both lease (e.g., minimum rent payments) and non-lease components (e.g., common-area or other maintenance costs). The Company accounts for each component separately based on the standalone price of each component. In addition, there are several operating leases with lease terms of less than one year and therefore, we have elected the practical expedient to exclude these short-term leases from our right of use (ROU) assets and lease liabilities. Most leases include one or more options to renew. The exercise of lease renewal options is typically at the sole discretion of management and is based on whether the extension options are reasonably certain to be exercised after giving proper consideration to all facts and circumstances of the lease. If management determines that the Company is reasonably certain to exercise the extension option(s), the additional term is included in the calculation of the lease liability. As most of our leases do not provide an implicit rate, we use the fully collateralized FHLB borrowing rate, commensurate with the lease terms based on the information available at the lease commencement date in determining the present value of the lease payments
Intangible Assets	Intangible Assets Intangible assets, other than goodwill, include core deposit intangibles and mortgage servicing rights (MSRs). Core deposit intangibles are a measure of the value of consumer demand and savings deposits acquired in business combinations accounted for as purchases MSRs arise from the Company originating certain loans for the express purpose of selling such loans in the secondary market. The Company maintains all servicing rights for these loans. The loans held for sale are carried at lower of cost or market. Originated MSRs are recorded by allocating total costs incurred between the loan and servicing rights based on their relative fair values. MSRs are amortized in proportion to the estimated servicing income over the estimated life of the servicing portfolio and measured annually for impairment. The recoverability of the carrying value of intangible assets is evaluated on an ongoing basis, and permanent declines in value, if any, are charged to expense.
Goodwill	Goodwill The Company utilizes a two-step process for testing the impairment of goodwill on at least an annual basis. This approach could cause more volatility in the Company’s reported net income because impairment losses, if any, could occur irregularly and in varying amounts. The Company may also perform a qualitative assessment to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying value. Based on the fair value of the reporting unit, no impairment of goodwill was recognized in 2020, 2019 or 2018.
Bank Owned Life Insurance	Bank Owned Life Insurance The Company has purchased life insurance policies on certain employees. Any death benefits received from a policy while the insured person is an active employee of the Bank will be split with the beneficiary of the policy. Under these agreements, the Bank receives the cash surrender value of the policy the benefit in excess of the cash surrender value and the remaining amount of the payout will be given to the beneficiary named by the insured person in the policy. The Company is the sole beneficiary of any death benefits received from non-active insured persons. Additionally, as a result of the MidCoast acquisition, the Company acquired life insurance policies on former MidCoast employees. The Company is owner and sole beneficiary of these policies. The Company acquired life insurance policies on former FNB employees and directors, as part of the acquisition of FNB. The policies obtained as part of the acquisition provide a fixed dollar benefit to the former employee or director beneficiaries, whether or not the insured person is affiliated with the Company at the time of his or her death. Bank owned life insurance is recorded at its cash surrender value, or the amount that can be realized. Increases in the cash surrender value are recognized as other non-interest income
Income Taxes	Income Taxes The Company and the Bank file a consolidated federal income tax return. Deferred tax assets and liabilities are computed based on the difference between the financial statement basis and income tax basis of assets and liabilities using the enacted marginal tax rates. Deferred income tax expenses or benefits are based on the changes in the net deferred tax asset or liability from period to period.
Derivatives	Derivatives Derivative financial instruments are recognized as assets or liabilities at fair value. The Company has interest rate swap agreements which are used as part of its asset liability management to help manage interest rate risk. The Corporation does not use derivatives for trading purposes. At the inception of a derivative contract, the Company designates the derivative as one of types based on the purpose of the contract and belief as to its effectiveness as a hedge. These three types are (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (“fair value hedge”), (2) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedge”), or (3) an instrument with no hedging designation (“stand-alone derivative”). For a fair value hedge, the gain or loss on the derivative, as well as the offsetting loss or gain on the hedged item, are recognized in current earnings as fair values change. For a cash flow hedge, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same periods during which the hedged transaction affects earnings. For both types of hedges, changes in the fair value of derivatives that are not highly effective in hedging the changes in fair value or expected cash flows of the hedged item are recognized immediately in current earnings. Changes in the fair value of derivatives that do not qualify for hedge accounting are reported currently in earnings, as non-interest income. Net cash settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in non-interest income. Cash flows on hedges are classified in the cash flow statement the same as the cash flows of the items being hedged. The Company formally documents the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions, at the inception of the hedging relationship. This documentation includes linking fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used are highly effective in offsetting changes in fair values or cash flows of the hedged items. The Company discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm, or treatment of the derivative as a hedge is no longer appropriate or intended. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as non-interest income. When a fair value hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted over the remaining life of the asset or liability. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that were accumulated in other comprehensive income are amortized into earnings over the same periods which the hedged transactions will affect earnings.
Employee Benefit Plans	Employee Benefit Plans The Company has noncontributory defined benefit pension plans covering employees hired before January 1, 2007 and employees acquired as part of the FNB acquisition. It is the Company’s policy to fund pension costs on a current basis to the extent deductible under existing tax regulations. Such contributions are intended to provide not only for benefits attributed to service to date, but also for those expected to be earned in the future. The plan acquired as part of the FNB acquisition was terminated in 2019. The Company has a defined contribution, 401(k) plan covering eligible employees. The employee may also contribute to the plan on a voluntary basis, up to a maximum percentage allowable not to exceed the limits of Code Sections 401(k). Under the plan, the Company also makes contributions on behalf of eligible employees, which vest immediately. For employees hired after January 1, 2007, in lieu of the pension plan, an additional annual discretionary 401(k) plan contribution is made and is equal to a percentage of an employee’s base compensation. The Company also has a profit-sharing plan for employees which provide tax-deferred salary savings to plan participants. The Company has a deferred compensation plan for directors who have elected to defer all or portions of their fees until their retirement or termination from service. The Company has a restricted stock plan which covers eligible employees and non-employee corporate directors. Under the plan, awards are granted based upon performance related requirements and are subject to certain vesting criteria. Compensation cost related to restricted stock is recognized based on the market price of the stock at the grant date over the vesting period. The Company has an employee stock purchase plan that allows employees to withhold money from their paychecks, which is then utilized to purchase shares of the Company’s stock on either the open market or through treasury stock, if shares are unavailable on the open market. The Company maintains a non-qualified supplemental executive retirement plan (“SERP”) for certain executives to compensate those executive participants in the Company’s noncontributory defined benefit pension plan whose benefits are limited by compensation limitations under current tax law. The SERP is considered an unfunded plan for tax and ERISA purposes and all obligations arising under the SERP are payable from the general assets of the Company. Expenses under the SERP are recognized as earned over the expected years of service. The Company maintains a non-tax qualified executive deferred compensation plan (“Deferred Compensation Plan”) for eligible employees designated by the board of directors. Each of the named executive officers are eligible to participate in the Deferred Compensation Plan. The Deferred Compensation Plan is considered an unfunded plan for tax and ERISA purposes and all obligations arising under the Deferred Compensation Plan are payable from the general assets of the Company.

This ASU was issued to improve and clarify various financial instruments topics, including the current expected credit losses (CECL) standard issued in 2016. The ASU includes seven issues that describe the areas of improvement and the related amendments to GAAP; they are intended to make the standards easier to understand and apply and to eliminate inconsistencies, and they are narrow in scope and are not expected to significantly change practice for most entities. Among its provisions, the ASU clarifies that all entities, other than public business entities that elected the fair value option, are required to provide certain fair value disclosures under ASC 825, Financial Instruments , in both interim and annual financial statements. It also clarifies that the contractual term of a net investment in a lease under Topic 842 should be the contractual term used to measure expected credit losses under Topic 326. Amendments related to ASU 2019-04 are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is not permitted before an entity’s adoption of ASU 2016-01. Amendments related to ASU 2016-13 for entities that have not yet adopted that guidance are effective upon adoption of the amendments in ASU 2016-13. Early adoption is not permitted before an entity’s adoption of ASU 2016-13. Amendments related to ASU 2016-13 for entities that have adopted that guidance are effective for fiscal years beginning after December 15, 2019, including interim periods within those years. Other amendments are effective upon issuance of this ASU. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s consolidated financial position or results of operations. In March 2020, the FASB issued ASU 2020-4, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, March 2020 , to provide temporary optional expedients and exceptions to the U.S. GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative reference rates, such as Secured Overnight Financing Rate. Entities can elect not to apply certain modification accounting requirements to contracts affected by what the guidance calls reference rate reform, if certain criteria are met. An entity that makes this election would not have to remeasure the contracts at the modification date or reassess a previous accounting determination. Also, entities can elect various optional expedients that would allow them to continue applying hedge accounting for hedging relationships affected by reference rate reform, if certain criteria are met, and can make a one-time election to sell and/or reclassify held-to-maturity debt securities that reference an interest rate affected by reference rate reform. The amendments in this ASU are effective for all entities upon issuance through December 31, 2022. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s consolidated financial position or results of operations. In August 2020, the FASB issued ASU 2020-6, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40) , which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. This ASU removes from U.S. GAAP the separation models for (1) convertible debt with a cash conversion feature and (2) convertible instruments with a beneficial conversion feature. As a result, entities will not separately present in equity an embedded conversion feature in such debt. Instead, they will account for a convertible debt instrument wholly as debt, and for convertible preferred stock wholly as preferred stock (i.e., as a single unit of account), unless (1) a convertible instrument contains features that require bifurcation as a derivative under ASC 815 or (2) a convertible debt instrument was issued at a substantial premium. This ASU requires entities to provide expanded disclosures about the terms and features of convertible instruments, how the instruments have been reported in the entity’s financial statements, and information about events, conditions, and circumstances that can affect how to assess the amount or timing of an entity’s future cash flows related to those instruments. The amendments in this ASU are effective for public business entities that are not smaller reporting companies, for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. For all other entities, this ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. The guidance may be early adopted for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. This Update is not expected to have a significant impact on the Company’s financial statements. In October 2020, the FASB issued ASU 2020-08, Codification Improvements to Subtopic 310-20, Receivables – Nonrefundable Fees and Other Costs, which clarifies that, for each reporting period, an entity should reevaluate whether a callable debt security is within the scope of ASC 310-20-35-33. For public business entities, ASU 2020-08 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early application is not permitted. For all other entities, ASU 2020-08 is effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. This Update is not expected to have a significant impact on the Company’s financial statements. In October 2020, the FASB issued ASU 2020-09, Debt (Topic 470): Amendments to SEC Paragraphs Pursuant to SEC Release No. 33-10762 , which codifies, as appropriate, the amended financial statement disclosure requirements in Regulation S-X Rules 13-01 and 13-02. The amendments are effective January 4, 2021. This Update did not have a significant impact on the Company’s financial statements. In October 2020, the FASB issued ASU 2020-10, Codification Improvements , which makes minor technical corrections and clarifications to the ASC. The amendments in Sections B and C of the ASU are effective for annual periods beginning after December 15, 2020, for public business entities. For all other entities, the amendments are effective for annual periods beginning after December 15, 2021, and interim periods within annual periods beginning after December 15, 2022. This Update is not expected to have a significant impact on the Company’s financial statements
Treasury Stock	Treasury Stock The purchase of the Company’s common stock is recorded at cost. At the date of subsequent reissue, the treasury stock account is reduced by the cost of such stock on a last-in-first-out basis.
Cash Flows	Cash Flows The Company utilizes the net reporting of cash receipts and cash payments for deposit, short-term borrowing and lending activities.
Trust, Brokerage and Insurance Assets and Income	T rust, Brokerage and Insurance Assets and Income Assets held by the Company in a fiduciary or agency capacity for its customers are not included in the consolidated financial statements since such assets are not assets of the Company. The majority 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. Trust fees are contractually agreed with each customer, and fee levels vary based mainly on the size of assets under management. None of the contracts with trust customers provide for incentive-based fees. In addition, 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. Brokerage and insurance commissions from the sales of investments and insurance products recognized on a trade date basis as the performance obligation is satisfied at the point in time in which the trade is processed. Additional fees are based on a percentage of the market value of customer accounts and billed on a monthly or quarterly basis. The Company’s performance obligation under the contracts with certain customers is generally satisfied through the passage of time as the Company monitors and manages the assets in the customer’s portfolio and is not dependent on certain return or performance level of the customer’s portfolio. Other performance obligations (such as the delivery of account statements to customers) are generally considered immaterial to the overall transaction price.

These anti-dilutive shares had per share prices ranging from $58.37-$62.93, $52.44-$62.93 and $47.81-$61.04 for 2020, 2019 and 2018, respectively.
Reclassification	Reclassification Certain of the prior year amounts have been reclassified to conform to the current year presentation. Such reclassifications had no effect on net income or stockholders’ equity.

REVENUE RECOGNITION [Abstract]
Revenue Recognition	Under ASC Topic 606, management determined that the primary sources of revenue emanating from interest and dividend income on loans and investments along with noninterest revenue resulting from investment security gains, loan servicing, gains on loans sold and earnings on bank owned life insurances are not within the scope of this topic. The main types of noninterest income within the scope of the standard are as follows: • Service charges on deposit accounts – The Company has contracts with its deposit customers where fees are charged if certain parameters are not met. These agreements can be cancelled at any time by either the Company or the deposit customer. Revenue from these transactions is recognized on a monthly basis as the Company has an unconditional right to the fee consideration. The Company also has transaction fees related to specific transactions or activities resulting from a customer request or activity that include overdraft fees, online banking fees, interchange fees, ATM fees and other transaction fees. All of these fees are attributable to specific performance obligations of the Company where the revenue is recognized at a defined point in time upon the completion of the requested service/transaction. • Trust fees – Typical contracts for trust services are based on a fixed percentage of the assets earned ratably over a defined period and billed on a monthly basis. Fees charged to customers’ accounts are recognized as revenue over the period during which the Company fulfills its performance obligation under the contract (i.e., holding client asset in a managed fiduciary trust account). For these accounts, the performance obligation of the Company is typically satisfied by holding and managing the customer’s assets over time. Other fees related to specific customer requests are attributable to specific performance obligations of the Company where the revenue is recognized at a defined point in time, upon completion of the requested service/transaction. • Gains (losses) on sale of other real estate owned – Gains and losses are recognized at the completion of the property sale when the buyer obtains control of the real estate and all of the performance obligations of the Company have been satisfied. Evidence of the buyer obtaining control of the asset include transfer of the property title, physical possession of the asset, and the buyer obtaining control of the risks and rewards related to the asset. In situations where the Company agrees to provide financing to facilitate the sale, additional analysis is performed to ensure that the contract for sale identifies the buyer and seller, the asset to be transferred, payment terms, and that the contract has a true commercial substance and that collection of amounts due from the buyer are reasonable. In situations where financing terms are not reflective of current market terms, the transaction price is discounted impacting the gain/loss and the carrying value of the asset. • Brokerage and insurance – Fees includes commissions from the sales of investments and insurance products recognized on a trade date basis as the performance obligation is satisfied at the point in time in which the trade is processed. Additional fees are based on a percentage of the market value of customer accounts and billed on a monthly or quarterly basis. The Company’s performance obligation under the contracts with certain customers is generally satisfied through the passage of time as the Company monitors and manages the assets in the customer’s portfolio and is not dependent on certain return or performance level of the customer’s portfolio. Fees for these services are billed monthly and are recorded as revenue at the end of the month for which the wealth management service has been performed. Other performance obligations (such as the delivery of account statements to customers) are generally considered immaterial to the overall transaction price.

Loan Modifications Related to COVID-19	The Company has elected to follow the loan modification guidance under Section 4013 of the CARES Act with regard to COVID-19 modifications made between March 1, 2020 and the earlier of either December 31, 2020 or the 60th day after the end of the COVID-19 national emergency. Under section 4013 of the CARES Act, loans less than 30 days past due as of December 31, 2019 will be considered current for COVID-19 modifications. A financial institution can then suspend the requirements under GAAP for loan modifications related to COVID-19 that would otherwise be categorized as a TDR, and suspend any determination of a loan modified as a result of COVID-19 as being a TDR, including the requirement to determine impairment for accounting purposes. Similarly, the Financial Accounting Standards Board has confirmed that short-term modifications made on a good-faith basis in response to COVID-19 to loan customers who were current prior to any relief are not TDRs. A modification of six months or less is considered to be a short-term loan modification. In response to the COVID-19 pandemic, the Company has prudently executed loan modifications for existing loan customers, which includes deferrals of interest and in certain cases deferrals of principal and interest. In addition, the risk-rating on COVID-19 modified loans did not change, and these loans will not be considered past due until after the deferral period is over and scheduled payments resume. The credit quality of these loans will be reevaluated after the deferral period ends. The following table presents information regarding loans which were subject to a loan modification related to COVID-19, with balances as of the date of modification and December 31, 2020, as well as the balance by modification type as of December 31, 2020.

Subsequent Default Recorded Investment	Recidivism, or the borrower defaulting on its obligation pursuant to a modified loan, results in the loan once again becoming a non-accrual loan. Recidivism occurs at a notably higher rate than do defaults on new origination loans, so modified loans present a higher risk of loss than do new origination loans. The following table presents the recorded investment in loans that were modified as TDRs during each 12-month period prior to the current reporting periods, which begin January 1, 2020, 2019 and 2018, respectively, and that subsequently defaulted during these reporting periods (dollars in thousands): December 31, 2020 December 31, 2019 December 31, 2018 Number of contracts Recorded investment Number of contracts Recorded investment Number of contracts Recorded investment Real estate loans: Commercial 1 $ 110 - $ - 2 $ 683 Agricultural - - 1 1,439 2 1,325 Other agricultural loans - - 3 137 1 161 Total recidivism 1 $ 110 4 $ 1,576 5 $ 2,169

Weighted-average Assumptions used to Determine Benefit Obligations and Net Periodic Benefit Cost (Income)	The weighted-average assumptions used to determine benefit obligations at December 31, 2020 and 2019 is summarized in the following table. Due to the decision to terminate the pension plan acquired as part of the FNB acquisition, the discount rate for the plans will be separated for the 2020 and 2019 disclosures. The change in the discount rate is the primary driver of the actuarial loss that occurred in 2020 of $1,810,000. 2020 2019 Discount rate FCCB Plan 2.00 % 2.75 % Discount rate FNB Plan 0.00 % 3.33 % Rate of compensation increase 3.00 % 3.00 % The weighted-average assumptions used to determine net periodic benefit cost (income) for the year ended December 31. Due to the decision to terminate the pension plan acquired as part of the FNB acquisition, the discount rate for the plans will be separated for 2019. The rate for 2018 represents a combined rate of the plans: 2020 2019 2018 Discount rate FCCB Plan 2.75 % 4.00 % 3.35 % Discount rate FNB Plan NA 3.49 % 3.35 % Expected long-term return on plan assets FCCB plan 7.00 % 7.00 % 7.00 % Expected long-term return on plan assets FNB plan NA NA 3.00 % Rate of compensation increase 3.00 % 3.00 % 3.00 %
Fair Value of Plan Assets	The long-term rate of return on plan assets gives consideration to returns currently being earned on plan assets as well as future rates expected to be earned. The investment objective is to maximize total return consistent with the interests of the participants and beneficiaries, and prudent investment management. The allocation of the pension plan assets is determined on the basis of sound economic principles and is continually reviewed in light of changes in market conditions. Asset allocation favors equity securities, with a target allocation of 50-70%. The target allocation for debt securities is 30-50%. At December 31, 2020, the pension plan had a sufficient cash and money market position in order to re-allocate the equity portfolio for diversification purposes and reduce risk in the total portfolio. The following table sets forth by level, within the fair value hierarchy as defined in footnote 18, the Plan’s assets at fair value as of December 31, 2020 and 2019 (dollars in thousands): 2020 Level I Level II Level III Total Allocation Assets Cash and cash equivalents $ 456 $ - $ - $ 456 3.4 % Equity Securities 5,709 - - 5,709 43.1 % Mutual Funds and ETF's 4,410 - - 4,410 33.3 % Corporate Bonds - 2,672 - 2,672 20.2 % Total $ 10,575 $ 2,672 $ - $ 13,247 100.0 % 2019 Level I Level II Level III Total Allocation Assets Cash and cash equivalents $ 924 $ - $ - $ 924 7.0 % Equity Securities 5,084 - - 5,084 38.3 % Mutual Funds and ETF's 4,175 - - 4,175 31.4 % Corporate Bonds - 3,094 - 3,094 23.3 % Total $ 10,183 $ 3,094 $ - $ 13,277 100.0 %

Vesting, Awarding and Forfeiting of Restricted Shares	The Company maintains a Restricted Stock Plan (the Plan) whereby employees and non-employee corporate directors are eligible to receive awards of restricted stock based upon performance related requirements. Awards granted under the Plan are in the form of the Company’s common stock and maybe subject to certain vesting requirements including in the case of employees, continuous employment or service with the Company. In April 2016, the Company’s stockholder authorized a total of 150,000 shares of the Company’s common stock to be made available under the Plan. As of December 31, 2020, 124,051 shares remain available to be issued under the Plan. The Plan assists the Company in attracting, retaining and motivating employees to make substantial contributions to the success of the Company and to increase the emphasis on the use of equity as a key component of compensation. The following table details the vesting, awarding and forfeiting of unearned restricted shares during 2020: 2020 Shares Weighted Average Market Price Outstanding, beginning of year 10,877 $ 60.11 Granted 5,160 50.89 Forfeited (337 ) 57.43 Vested (5,498 ) 59.37 Outstanding, end of year 10,202 $ 55.93

REGULATORY MATTERS [Abstract]
Capital Ratios under Banking Regulations	As permitted by applicable federal regulation, the Bank has opted to use the community bank leverage ratio (the “CBLR”) framework for determining its capital adequacy. Under the CBLR framework a qualifying community bank is considered well-capitalized if its leverage ratio (Tier 1 capital divided by average total consolidated assets) exceeds 9%. Following the passage of the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act in response to the COVID-19 pandemic, the federal banking regulators revised the CBLR framework as follows: (i) beginning in the second quarter of 2020, a qualifying community bank need only have a leverage ratio of at least 8%, subject to the other qualifying requirements, and (ii) if a qualifying community bank’s leverage ratio falls below 8%, then it will have two calendar quarters to maintain a leverage ratio of 7% or greater. These revisions under the CARES Act are effective April 23, 2020 and will terminate upon the earlier of the termination of the national emergency related to COVID-19 or December 31, 2020. Following such termination there is a grace period for returning to the 9% CBLR threshold. The CBLR will be set at 8% for the remainder of 2020, 8.5% for 2021, and 9% thereafter. The grace period is also adjusted to account for the graduating increase. As a result, in 2020 and 2021, a qualifying community bank utilizing the grace period must maintain a CBLR of at least 7% and 7.5%, respectively. Thereafter, a qualifying community bank utilizing the grace period must maintain a CBLR of at least 8%. If a qualifying community bank fails to maintain the applicable minimum CBLR during the grace period, or if it is unable to restore compliance with the CBLR within the grace period, then it will revert to the Basel III capital framework and the normal Prompt Corrective Action capital categories will apply. At December 31, 2020, the Bank was considered “well-capitalized” under the CBLR framework, with a leverage ratio of 8.75%. The Bank’s computed risk‑based capital ratios are as follows as of December 31, 2019 (dollars in thousands): Actual For Capital Adequacy Purposes To Be Well Capitalized Under Prompt Corrective Action Provisions 2019 Amount Ratio Amount Ratio Amount Ratio Total Capital (to Risk Weighted Assets): Company $ 154,708 14.04 % $ 88,166 8.00 % $ 110,208 10.00 % Bank $ 146,925 13.34 % $ 88,102 8.00 % $ 110,128 10.00 % Tier 1 Capital (to Risk Weighted Assets): Company $ 140,929 12.79 % $ 66,125 6.00 % $ 88,166 8.00 % Bank $ 133,156 12.09 % $ 66,077 6.00 % $ 88,102 8.00 % Common Equity Tier 1 Capital (to Risk Weighted Assets): Company $ 133,429 12.11 % $ 49,593 4.50 % $ 71,635 6.50 % Bank $ 133,156 12.09 % $ 49,557 4.50 % $ 71,583 6.50 % Tier 1 Capital (to Average Assets): Company $ 140,929 9.77 % $ 57,705 4.00 % $ 72,132 5.00 % Bank $ 133,156 9.23 % $ 57,681 4.00 % $ 72,101 5.00 %

LEASES [Abstract]
Right of Use Assets and Lease Liabilities	The following table represents the Consolidated Balance Sheet classification of the Company’s ROU assets and lease liabilities (in thousands) . The Company elected not to include short-term leases (i.e., leases with initial terms of twelve months or less), on the Consolidated Balance Sheet. Balance at December 31, Lease Type 2020 2019 Affected line item on the Consolidated Balance Sheet Right of Use Assets Operating $ 2,286 $ 1,163 Other Assets Lease Liabilities: Operating $ 2,295 $ 1,163 Other Liabilities
Weighted Average Remaining Lease Term and Discount Rate	The calculated amount of the ROU assets and lease liabilities in the table above are impacted by the length of the lease term and the discount rate used to present value the minimum lease payments. The Company’s lease agreements often include one or more options to renew at the Company’s discretion. If at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the ROU asset and lease liability. Regarding the discount rate, Topic 842 requires the use of the rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term. For operating leases existing prior to January 1, 2019, the rate for the remaining lease term as of January 1, 2019 was used. The following table displays the weighted average remaining lease term and the weighted average discount rate for the Company’s operating leases outstanding as of December 31, 2020: Operating Weighted average term (years) 5.57 Weighted average discount rate 1.97 %
Lease Costs and Other Lease Information	The following table represents lease costs and other lease information for the years ended December 31, 2020, and 2019, respectively (in thousands). As the Company elected not to separate lease and non-lease components and instead to account for them as a single lease component, the variable lease cost primarily represents variable payments such as common area maintenance and utilities.

[1]	We utilize securities sold under agreements to repurchase to facilitate the needs of our customers and to facilitate secured short-term funding needs. Securities sold under agreements to repurchase are stated at the amount of cash received in connection with the transaction. We monitor collateral levels on a continuous basis. We may be required to provide additional collateral based on the fair value of the underlying securities. Securities pledged as collateral under repurchase agreements are maintained with our safekeeping agents. The collateral pledged on the repurchase agreements by the remaining contractual maturity of the repurchase agreements in the Consolidated Balance Sheets as of December 31, 2020 and December 31, 2019 is presented in the following tables (in thousands).
[2]	FHLB Advances consist of an “Open RepoPlus” agreement with the FHLB of Pittsburgh. FHLB “Open RepoPlus” advances are short-term borrowings that bear interest based on the FHLB discount rate or Federal Funds rate, whichever is higher.  The Company has a borrowing limit of $690,544,000, inclusive of any outstanding advances and letters of credit. FHLB advances are secured by a blanket security agreement that includes the Company’s FHLB stock, as well as certain investment and mortgage-backed securities held in safekeeping at the FHLB and certain residential and commercial mortgage loans.  A portion of these advances, $25.0 million, are subject to interest rate swap arrangements. See Note 17 for additional information.
[3]	The federal funds lines consist of unsecured lines from two third party banks at market rates.  The Company has a borrowing limit totaling $34,000,000, inclusive of any outstanding balances.  No specific collateral is required to be pledged for these borrowings.
[4]	The Federal Reserve Bank Borrower in Custody (FRB BIC) Line consists of a borrower in custody in agreement opened in January 2010 with the Federal Reserve Bank of Philadelphia secured by municipal loans maintained in the Company's possession.  As of December 31, 2020 and 2019, the Company has a borrowing limit of $4,379,000 and $10,902,000, respectively, inclusive of any outstanding advances. The approximate carrying value of the municipal loan collateral was $12,932,000 and $26,895,000 as of December 31, 2020 and 2019, respectively.
[5]	In December 2003, the Company formed a special purpose entity (“Entity”) to issue $7,500,000 of floating rate obligated mandatory redeemable trust preferred securities as part of a pooled offering.  The rate was determined quarterly and floated based on the 3 month LIBOR plus 2.80 percent.   The Entity may redeem them, in whole or in part, at face value after December 17, 2008, and on a quarterly basis thereafter.  The Company borrowed the proceeds of the issuance from the Entity in December 2003 in the form of a $7,500,000 note payable.  Debt issue costs of $75,000 have been capitalized and fully amortized as of December 31, 2008.  Under current accounting rules, the Company’s minority interest in the Entity was recorded at the initial investment amount and is included in the other assets section of the balance sheet.  The Entity is not consolidated as part of the Company’s consolidated financial statements.  The $7,500,000 note payable is subject to an interest rate swap  arrangement. See  Note 17 for additional information.
