Accounting Policies [Abstract]
Summary of Significant Accounting Policies	(1.) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Financial Institutions, Inc. (individually referred to herein as the “Parent Company” and together with all of its subsidiaries, collectively referred to herein as the “Company”) is a financial holding company organized in 1931 under the laws of New York State (“New York”). At December 31, 2020, the Company conducted its business through its four subsidiaries: Five Star Bank (the “Bank”), a New York chartered bank; SDN Insurance Agency, LLC (“SDN”), a full service insurance agency; and Courier Capital, LLC (“Courier Capital”) and HNP Capital, LLC (“HNP Capital”), SEC-registered investment advisory and wealth management firms. The Company provides a full range of banking and related financial services to consumer, commercial and municipal customers through its bank and nonbank subsidiaries. The accounting and reporting policies conform to general practices within the banking industry and to U.S. generally accepted accounting principles (“GAAP”). The Company has evaluated events and transactions for potential recognition or disclosure through the day the financial statements were issued and determined there were no material recognizable subsequent events. The following is a description of the Company’s significant accounting policies. (a.) Principles of Consolidation The consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. (b.) Use of Estimates In preparing the consolidated financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amount of assets and liabilities as of the date of the statement of financial condition and reported amounts of revenue and expenses during the reporting period. Material estimates relate to the determination of the allowance for credit losses, the carrying value of goodwill and deferred tax assets, and assumptions used in the defined benefit pension plan accounting. These estimates and assumptions are based on management’s best estimates and judgment and are evaluated on an ongoing basis using historical experience and other factors, including the current economic environment. The Company adjusts these estimates and assumptions when facts and circumstances dictate. As future events cannot be determined with precision, actual results could differ significantly from the Company’s estimates. (c.) Cash Flow Reporting Cash and cash equivalents include cash and due from banks, federal funds sold and interest-bearing deposits in other banks. Net cash flows are reported for loans, deposit transactions and short-term borrowings. Supplemental cash flow information is summarized as follows for the years ended December 31 (in thousands): 2020 2019 2018 Supplemental information: Cash paid for interest $ 28,875 $ 37,225 $ 28,626 Cash paid for income taxes, net of refunds received 7,462 9,853 3,527 Noncash investing and financing activities: Real estate and other assets acquired in settlement of loans $ 2,966 $ 557 $ 642 Accrued and declared unpaid dividends 4,535 4,365 4,187 (Decrease) increase in net unsettled security purchases - (2,650 ) 2,650 Securities transferred from held to maturity to available for sale (at cost) - 26,175 - Common stock issued for Courier Capital contingent earn-out - 1,151 - Assets acquired and liabilities assumed in business combinations: Fair value of assets acquired - - 2,561 Fair value of liabilities assumed - - 128 (1.) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) (d.) Investment Securities Investment securities are classified as either available for sale (“AFS”) or held to maturity (“HTM”). Debt securities that management has the positive intent and ability to hold to maturity are classified as held to maturity and are recorded at amortized cost. Other investment securities are classified as available for sale and recorded at fair value, with unrealized gains and losses excluded from earnings and reported as a component of comprehensive income (loss) and shareholders’ equity. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. (e.) Loans Held for Sale and Loan Servicing Rights The Company generally makes the determination of whether to identify a mortgage as held for sale at the time the loan is closed based on the Company’s intent and ability to hold the loan. Loans held for sale are recorded at the lower of cost or market computed on the aggregate portfolio basis. The amount by which cost exceeds market value, if any, is accounted for as a valuation allowance with changes included in the determination of results of operations for the period in which the change occurs. The amount of loan origination costs and fees are deferred at origination and recognized as part of the gain or loss on sale of the loans, determined using the specific identification method, in the consolidated statements of income. The Company originates and sells certain residential real estate loans in the secondary market. The Company typically retains the right to service the mortgages upon sale. Mortgage-servicing rights (“MSRs”) represent the cost of acquiring the contractual rights to service loans for others. MSRs are recorded at their fair value at the time a loan is sold and servicing rights are retained. MSRs are reported in other assets in the consolidated statements of financial position and are amortized to noninterest income in the consolidated statements of income in proportion to and over the period of estimated net servicing income. The Company uses a valuation model that calculates the present value of future cash flows to determine the fair value of servicing rights. In using this valuation method, the Company incorporates assumptions to estimate future net servicing income, which include estimates of the cost to service the loan, the discount rate, an inflation rate and prepayment speeds. On a quarterly basis, the Company evaluates its MSRs for impairment and charges any such impairment to current period earnings. In order to evaluate its MSRs the Company stratifies the related mortgage loans on the basis of their predominant risk characteristics, such as interest rates, year of origination and term, using discounted cash flows and market-based assumptions. Impairment of MSRs is recognized through a valuation allowance, determined by estimating the fair value of each stratum and comparing it to its carrying value. Subsequent increases in fair value are adjusted through the valuation allowance, but only to the extent of the valuation allowance. Mortgage loan servicing includes collecting monthly mortgagor payments, forwarding payments and related accounting reports to investors, collecting escrow deposits for the payment of mortgagor property taxes and insurance, paying taxes and insurance from escrow funds when due and administrating foreclosure actions when necessary. Loan servicing income (a component of noninterest income in the consolidated statements of income) consists of fees earned for servicing mortgage loans sold to third parties, net of amortization expense and impairment losses associated with capitalized mortgage servicing assets. (f.) Loans Loans are classified as held for investment when management has both the intent and ability to hold the loan for the foreseeable future, or until maturity or payoff. Loans are carried at the principal amount outstanding, net of any unearned income and unamortized deferred fees and costs on originated loans. Loan origination fees and certain direct loan origination costs are deferred, and the net amount is amortized into net interest income over the contractual life of the related loans or over the commitment period as an adjustment of yield. Interest income on loans is based on the principal balance outstanding computed using the effective interest method. (1.) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) A loan is considered delinquent when a payment has not been received in accordance with the contractual terms. The accrual of interest income for commercial loans is discontinued when there is a clear indication that the borrower’s cash flow may not be sufficient to meet payments as they become due, while the accrual of interest income for retail loans is discontinued when loans reach specific delinquency levels. Loans are generally placed on nonaccrual status when contractually past due 90 days or more as to interest or principal payments, unless the loan is well secured and in the process of collection. Additionally, if management becomes aware of facts or circumstances that may adversely impact the collectability of principal or interest on loans, it is management’s practice to place such loans on a nonaccrual status immediately, rather than delaying such action until the loans become 90 days past due. When a loan is placed on nonaccrual status, previously accrued and uncollected interest is reversed, amortization of related deferred loan fees or costs is suspended, and income is recorded only to the extent that interest payments are subsequently received in cash and a determination has been made that the principal balance of the loan is collectible. If collectability of the principal is in doubt, payments received are applied to loan principal. A nonaccrual loan may be returned to accrual status when all delinquent principal and interest payments become current in accordance with the terms of the loan agreement, the borrower has demonstrated a period of sustained performance (generally a minimum of six months) and the ultimate collectability of the total contractual principal and interest is no longer in doubt. The Company’s loan policy dictates the guidelines to be followed in determining when a loan is charged-off. All charge offs are approved by the Bank’s senior loan officers or loan committees, depending on the amount of the charge off, and are reported in aggregate to the Bank’s Board of Directors. Commercial business and commercial mortgage loans are charged-off when a determination is made that the financial condition of the borrower indicates that the loan will not be collectible in the ordinary course of business. Residential mortgage loans and home equities are generally charged-off or written down when the credit becomes severely delinquent and the balance exceeds the fair value of the property less costs to sell. Indirect and other consumer loans, both secured and unsecured, are generally charged-off in full during the month in which the loan becomes 120 days past due, unless the collateral is in the process of repossession in accordance with the Company’s policy. A loan is accounted for as a troubled debt restructuring if the Company, for economic or legal reasons related to the borrower’s financial condition, grants a significant concession to the borrower that it would not otherwise consider. A troubled debt restructuring may involve the receipt of assets from the debtor in partial or full satisfaction of the loan, or a modification of terms such as a reduction of the stated interest rate or face amount of the loan, a reduction of accrued interest, an extension of the maturity date at a stated interest rate lower than the current market rate for a new loan with similar risk, or some combination of these concessions. Troubled debt restructurings generally remain on nonaccrual status until there is a sustained period of payment performance (usually six months or longer) and there is a reasonable assurance that the payments will continue. See Allowance for Credit Losses below for further policy discussion and see Note 6 – Loans for additional information. (g.) Off-Balance Sheet Financial Instruments In the ordinary course of business, the Company enters into off-balance sheet financial instruments consisting of commitments to extend credit, standby letters of credit and financial guarantees. Such financial instruments are recorded in the consolidated financial statements when they are funded or when related fees are incurred or received. The Company periodically evaluates the credit risks inherent in these commitments and establishes loss allowances for such risks if and when these are deemed necessary. The Company recognizes as liabilities the fair value of the obligations undertaken in issuing the guarantees under the standby letters of credit, net of the related amortization at inception. The fair value approximates the unamortized fees received from the customers for issuing the standby letters of credit. The fees are deferred and recognized on a straight-line basis over the commitment period. Standby letters of credit outstanding typically have original terms ranging from one to five years. Fees received for providing loan commitments and letters of credit that result in loans are typically deferred and amortized to interest income over the life of the related loan, beginning with the initial borrowing. Fees on commitments and letters of credit are amortized to other income as banking fees and commissions over the commitment period when funding is not expected. (h.) Allowance for Credit Losses The allowance for credit losses is established through charges to earnings in the form of a provision for credit losses. When a loan or portion of a loan is determined to be uncollectible, the portion deemed uncollectible is charged against the allowance and subsequent recoveries, if any, are credited to the allowance. (1.) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) Portfolio Segmentation and “Pooled Loans” Calculation Loans are pooled based on their homogeneous risk characteristics. Once loans have been segmented into pools, a loss rate is applied to the amortized cost basis. The Company has divided its portfolio into six segments, as the loans within the segments have similar characteristics. Characteristics considered include: purpose, tenor, amortization, repayment source, payment frequency, collateral and recourse. The Company has identified six portfolio segments of loans including Commercial Loans/Lines, Commercial Mortgage, Indirect Loans, Direct Loans, Residential Lines of Credit, and Residential Loans. The Company utilizes the Discounted Cash Flow (“DCF”) method for its pooled segment calculation. The DCF method implements a Probability of Default with Loss Given Default and Exposure at Default estimation. The Probability of Default and Loss Given Default are applied to future cash flows that are adjusted to present value and these discounted expected losses become the Allowance for Credit Losses. DCF analysis is reliant upon a variety of loan-level data, peripheral model outputs and key assumptions. The data fields required to create the contractual portion of the forward-looking cash flow schedule relate to the terms of each loan and include information regarding payment amount, payment frequency, interest rate, interest type, maturity date, amortization term, etc. Contractual terms must be adjusted for prepayments to arrive at expected cashflows. The Company modeled amortizing/installment notes with a prepayment rate, annualized to one-year. For loans where principal collection is dominated by borrower election, e.g. lines of credit, interest-only, etc., and not by contractual obligation, the Company modeled a statistical tendency to repay as a curtailment rate, normalized to a one-year rate. The Company uses forecasts to predict how modeled economic factors will perform. The Company currently elects to forecast economic factors over a period for which it can produce a reliable and defensible forecast from widely accepted economic forecast resources. After the forecast period, the following eight quarters are reverted on a straight-line basis to the economic factor’s average. The Company uses an eight-quarter straight-line reversion to reduce the potential for a spike impact on the model caused by a rapid reversion. Additionally, as the Company is past its point of forecast, a straight-line reversion represents a most-likely scenario absent a hard forecast. In the Company’s analysis at the portfolio level, it found that the best model for predicting defaults considers the National Unemployment Rate. With the large number of observations afforded by using peer data, the default curve is less sensitive to unusual loss events and has a much smoother shape. The national unemployment rate is an extremely strong predictor of defaults and explains almost all variation in the default rate. CECL requires calculating a reserve based on a life of loan basis. The life of loan is assumed with consideration of prepayments and contractual maturity dates. If a given loan does not have a populated maturity date, based upon historical experience, the Company elected to amortize the loan for a length of time equal to the average life of the loan’s segment before the remaining balance will balloon with the exception of Commercial Demand Lines of Credit where the Company uses one year, reflecting the demand nature of these exposures with annual review. Management also considers Qualitative Factors (“QF”) that are likely to cause estimated credit losses with the Company’s existing portfolio to differ from historical loss experience, including but not limited to: national and local economic trends and conditions (excluding national unemployment), levels and trends in delinquencies, non-accrual loans and classified assets, trends in volume, terms and concentrations of loans, changes in lending policies and procedures, Quality of Credit Review function and administration, and changes in regulatory environment. The Company will periodically assess what adjustments are necessary to qualitatively adjust the ACL based on their assessment of current expected credit losses. The range for the QF in a specific pool represents the difference, in basis points between the portfolio segment loss explained by the regression analysis (r-squared factor) and the total loss for that period, looking back to 2006, when the Company experienced its highest four quarter loss rate. In this approach, the Company is capturing, based upon historical experience, its largest potential loss rate. Where possible, the QF are calculated using available data sources to support the allocation of basis points within the ranges. For example, delinquency for a segment is mapped backed to 2006 and current delinquency is allocated a QF based upon where it lies in that range. (1.) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) Individually Analyzed Loans Excluded from pooled analysis are loans to be individually analyzed due to the assets not maintaining similar risk characteristics to those in the six designated segments. These loans are generally considered to be collateral dependent and, therefore, an analysis of the collateral position versus the pooled loan discounted cash flow approach better reflects the potential loss. Individually analyzed accounts include: loans over 90 days past due, loans marked as Trouble Debt Restructure (“TDR”), loans placed on non-accruals status and criticized assets with exposure greater than $2.0 million. In addition, certain commercial loans are on long term deferral due to the impacts of the COVID-19 pandemic. While not criticized assets, these loans reflect unique characteristics and warrant individual analysis. Management reviewed these loans and elected to remove certain loans from the pooled loan analysis based upon characteristics including industry, which evidence a higher risk of loss from the impact of the pandemic. These loans were individually analyzed, and reserves allocated to them based upon collateral position. Management continues to assess the status of these loans for risk characteristics. Held to Maturity (“HTM”) Debt Securities The Company’s HTM debt securities are also required to utilize the current expected credit losses approach to estimate expected credit losses. The Company’s HTM debt securities included securities that are issued by U.S. government agencies or U.S. government-sponsored enterprises. These securities carry the explicit and/or implicit guarantee of the U.S. government, are widely recognized as “risk free,” and have a long history of zero credit loss. The Company also carries a portfolio of HTM municipal bonds. The Company measures its allowance for credit losses on HTM debt securities on a collective basis by major security type. The estimate is based on historical credit losses, if any, adjusted for current conditions and reasonable and supportable forecasts. The Company considers the nature of the collateral, potential future changes in collateral values and available loss information. Available for Sale (“AFS”) Debt Securities For AFS securities in an unrealized loss position, we first assess whether (i) we intend to sell, or (ii) it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. If either case is affirmative, any previously recognized allowances are charged-off and the security's amortized cost is written down to fair value through income. If neither case is affirmative, the security is evaluated to determine whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and any adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. Adjustments to the allowance are reported in our income statement as a component of provision for credit losses. AFS securities are charged-off against the allowance or, in the absence of any allowance, written down through income when deemed uncollectible by management or when either of the aforementioned criteria regarding intent or requirement to sell is met. (1.) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) Accrued Interest Receivable Upon adoption of ASU 2016-13 and its related amendments on January 1, 2020, the Company made the following elections regarding accrued interest receivable: • Presenting accrued interest receivable balances separately within other assets on the statement of financial condition. • Excluding accrued interest receivable that is included in the amortized cost of financing receivables and debt securities from related disclosure requirements. • Continuing our policy to write off accrued interest receivable by reversing interest income. For commercial loans, the write off typically occurs upon becoming 90 days past due. For consumer loans, the write off typically occurs upon becoming 120 days past due. Historically, the Company has not experienced uncollectible accrued interest receivable on its investment securities. However, the Company would generally write off accrued interest receivable by reversing interest income if the Company does not reasonably expect to receive payments. Due to the timely manner in which accrued interest receivables are written off, the amounts of such write offs are immaterial. • The Company had made the election with the adoption of ASU 2016-13 of not measuring an allowance for credit losses for accrued interest receivable due to the Company’s policy of writing off uncollectible accrued interest receivable balances in a timely manner, as described above. Reserve for Unfunded Commitments The reserve for unfunded commitments (the “Unfunded Reserve”) represents the expected credit losses on off-balance sheet commitments such as unfunded commitments to extend credit and standby letters of credit. However, a liability is not recognized for commitments unconditionally cancellable by the Company. The Unfunded Reserve is recognized as a liability (other liabilities in the consolidated statements of financial condition), with adjustments to the reserve recognized as a provision for credit loss expense in the consolidated statements of income. The Unfunded Reserve is determined by estimating expected future fundings, under each segment, and applying the expected loss rates. Expected future fundings are based on historical averages of funding rates (i.e., the likelihood of draws taken). Average funding rates are determined based on the most recent 20 quarters (5 years) of actual fundings on lines of credit. The average funding rate for each segment is compared to the current funding rate on each line to determine the average fundings available to be drawn. The fund up rate (the difference between the average funding rate and the current funding rate) for each segment is then applied within the CECL model to the unfunded commitment balance to estimate the expected future fundings under each segment. The loss rate derived for each segment in the current CECL calculation is then applied to the expected future fundings to derive the estimate of allowance for credit losses for unfunded commitments. (i.) Other Real Estate Owned Other real estate owned consists of properties acquired through foreclosure or by acceptance of a deed in lieu of foreclosure. These assets are initially recorded at fair value less estimated costs to sell, which establishes the cost basis. Subsequently, other real estate owned is carried at the lower of the cost basis or fair value less estimated selling costs. At the time of foreclosure, or when foreclosure occurs in-substance, the excess, if any, of the loan over the fair market value of the assets received, less estimated selling costs, is charged to the allowance for credit losses and any subsequent valuation write-downs are charged to other expense. In connection with the determination of the allowance for credit losses and the valuation of other real estate owned, management obtains appraisals for properties. Operating costs associated with the properties are charged to expense as incurred. Gains on the sale of other real estate owned are included in income when title has passed and the sale has met the minimum down payment requirements prescribed by GAAP. The balance of other real estate owned was $3.0 million and $468 thousand at December 31, 2020 and 2019, respectively. (1.) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) (j.) Company Owned Life Insurance The Company holds life insurance policies on certain current and former employees. The Company is the owner and beneficiary of the policies. The cash surrender value of these policies is included as an asset on the consolidated statements of financial condition, and any increase in cash surrender value is recorded as noninterest income on the consolidated statements of income. In the event of the death of an insured individual under these policies, the Company would receive a death benefit which would be recorded as noninterest income. (k.) Premises and Equipment Premises and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation is computed on the straight-line method over the estimated useful lives of the assets. The Company generally amortizes buildings and building improvements over a period of 15 to 39 years and software, furniture and equipment over a period of 3 to 10 years. Leasehold improvements are amortized over the shorter of the lease term or the useful life of the improvements. Premises and equipment are periodically reviewed for impairment or when circumstances present indicators of impairment. (l.) Goodwill and Other Intangible Assets The excess of the cost of an acquisition over the fair value of the net assets acquired consists primarily of goodwill, core deposit intangibles, and other identifiable intangible assets. Intangible assets are acquired assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset, or liability. The Company’s intangible assets consist of core deposits and other intangible assets (primarily customer relationships). Core deposit intangible assets are amortized on an accelerated basis over their estimated life of approximately nine and a half years Goodwill is not amortized but, instead, is subject to impairment tests on at least an annual basis, and more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The impairment testing process is conducted by assigning net assets and goodwill to each reporting unit. An initial qualitative evaluation is made to assess the likelihood of impairment and determine whether further quantitative testing to calculate the fair value is necessary. When the qualitative evaluation indicates that impairment is more likely than not, quantitative testing is required whereby the fair value of each reporting unit is calculated and compared to the recorded book value. If the calculated fair value of the reporting unit exceeds its carrying value, then goodwill is not considered impaired. However, if the carrying value of a reporting unit exceeds its calculated fair value, a goodwill impairment charge is recognized. See Note 8 for additional information on goodwill and other intangible assets. (m.) Federal Home Loan Bank (“FHLB”) and Federal Reserve Bank (“FRB”) Stock The non-marketable investments in FHLB and FRB stock are included in other assets in the consolidated statements of financial condition at par value or cost and are periodically reviewed for impairment. The dividends received relative to these investments are included in other noninterest income in the consolidated statements of income. As a member of the FHLB system, the Company is required to maintain a specified investment in FHLB of New York (“FHLBNY”) stock in proportion to its volume of certain transactions with the FHLB. FHLBNY stock totaled $2.6 million and $14.6 million as of December 31, 2020 and 2019, respectively. As a member of the FRB system, the Company is required to maintain a specified investment in FRB stock based on a ratio relative to the Company’s capital. FRB stock totaled $6.1 million as of December 31, 2020 and 2019. (1.) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) (n.) Equity Method Investments The Company has investments in limited partnerships, primarily Small Business Investment Companies, and accounts for these investments under the equity method. These investments are included in other assets in the consolidated statements of financial condition and totaled $7.9 million and $7.6 million as of December 31, 2020 and 2019, respectively. (o.) Derivative Instruments and Hedging Activities Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 815, Derivatives and Hedging (“ASC 815”), provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (a) how and why an entity uses derivative instruments, (b) how the entity accounts for derivative instruments and related hedged items, and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. Further, qualitative disclosures are required that explain the Company’s objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative instruments. As required by ASC 815, the Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative. Changes in fair value of the Company’s derivatives

Restructuring And Related Activities [Abstract]
Restructuring Charges	(3.) RESTRUCTURING CHARGES On July 17, 2020, the Bank announced management’s decision to adopt a full-service branch model that streamlines retail branches to better align with shifting customer needs and preferences. The transformation resulted in six branch closures and a reduction in staffing. The announcement was the result of a nine-month comprehensive assessment of all lines of business and functional areas, conducted in partnership with a leading process improvement organization. The data-driven analysis identified, among other things, overlapping service areas, automation opportunities and streamlining of processes and operations that would enhance customer experiences and facilitate the long-term sustainability of current and future branches. The announced consolidations represented about ten percent of the branch network and impacted approximately six percent of the total Company workforce. Where possible, those impacted were offered alternative roles or the opportunity to apply for open positions in other areas of the Company. Separated associates received a comprehensive severance package based on tenure. In October 2020, the Company announced the planned closure of one additional branch in January 2021. This location was not included in the branch consolidations announced in July, as alternative options were being considered and consolidation was not possible given its significant distance from other Bank branches. For the year ended December 31, 2020, the Company incurred total pre-tax expense related to the branch closures of approximately $1.7 million, including approximately $0.2 million in employee severance, $0.5 million in lease termination costs and $1.0 million in valuation adjustments on branch facilities. The Company recognized all of these expenses during 2020. The Company expects approximately $0.9 million of total costs will result in future cash expenditures. The Company anticipates annual expense savings of approximately $2.7 million as a result of these branch closures. The following table represents the consolidated statements of income classification of the Company’s restructuring charges (in thousands): Income Statement Location 2020 2019 2018 December 31, 2020 Severance costs Salaries and employee benefits $ 242 $ - $ - Lease termination costs Restructuring charges 454 - - Valuation adjustments Restructuring charges 1,038 - - Total $ 1,734 $ - $ - The following table represents the changes in the restructuring reserve (in thousands): Balance, January 1, 2019 $ - No activity during the period - Balance, December 31, 2019 - Restructuring charges 1,734 Cash payments (287 ) Charges against assets (202 ) Balance, December 31, 2020 $ 1,245

INVESTMENT SECURITIES (Continued) The total number of security positions in the investment portfolio in an unrealized loss position at December 31, 2020 was eight compared to 91 at December 31, 2019. At December 31, 2020, the Company had a position in one investment security with a fair value of eight thousand dollars and a total unrealized loss of less than one thousand dollars that has been in a continuous unrealized loss position for more than 12 months. At December 31, 2020, there were a total of seven securities positions in the Company’s investment portfolio with a fair value of $29.1 million and a total unrealized loss of $68 thousand that had been in a continuous unrealized loss position for less than 12 months. At December 31, 2019, the Company had positions in 34 investment securities with a fair value of $47.2 million and a total unrealized loss of $659 thousand that have been in a continuous unrealized loss position for more than 12 months. At December 31, 2019, there were a total of 57 securities positions in the Company’s investment portfolio with a fair value of $178.7 million and a total unrealized loss of $1.6 million that had been in a continuous unrealized loss position for less than 12 months. The unrealized loss on investment securities was predominantly caused by changes in market interest rates subsequent to purchase. The fair value of most of the investment securities in the Company’s portfolio fluctuates as market interest rates change. Securities Available for Sale As of December 31, 2020, no allowance for credit losses has been recognized on available for sale securities in an unrealized loss position as management does not believe any of the securities are impaired due to reasons of credit quality. This is based upon our analysis of the underlying risk characteristics, including credit ratings, and other qualitative factors related to our available for sale securities and in consideration of our historical credit loss experience and internal forecasts. The issuers of these securities continue to make timely principal and interest payments under the contractual terms of the securities. Furthermore, management does not have the intent to sell any of the securities classified as available for sale in the table above and believes that it is more likely than not that we will not have to sell any such securities before a recovery of cost. The unrealized losses are due to increases in market interest rates over the yields available at the time the underlying securities were purchased. The fair value is expected to recover as the securities approach their maturity date or repricing date or if market yields for such investments decline. Securities Held to Maturity The Company’s HTM investment securities include debt securities that are issued by U.S. government agencies or U.S. government-sponsored enterprises. These securities carry the explicit and/or implicit guarantee of the U.S. government, are widely recognized as “risk free,” and have a long history of zero credit loss. In addition, the Company’s HTM investment securities include debt securities that are issued by state and local government agencies, or municipal bonds. The Company monitors the credit quality of our municipal bonds through the use of a credit rating agency or by ratings that are derived by an internal scoring model. The scoring methodology for the internally derived ratings is based on a series of financial ratios for the municipality being reviewed as compared to typical industry figures. This information is used to determine the financial strengths and weaknesses of the municipality, which is indicated with a numeric rating. This number is then converted into a letter rating to better match the system used by the credit rating agencies. As of December 31, 2020, $135.7 million of our municipal bonds were rated as an equivalent to Standard & Poor’s A/AA/AAA, with $8.5 million internally rated to be the equivalent of Standard & Poor’s A/AA/AAA rating. Additionally, one municipal bond is rated below investment grade, with a BB+ Standard & Poor’s equivalent rating. The below investment grade bond was recently upgraded from a Standard & Poor’s equivalent rating of BB-, represents exposure of $279 thousand, or 0.19% of the municipal bond portfolio and is closely monitored for repayment. As of December 31, 2020, the Company had no past due or nonaccrual held to maturity investment securities.

LOANS (Continued) The CARES Act was passed by Congress and signed into law on March 27, 2020. The CARES Act established the PPP, an expansion of the SBA’s 7(a) loan program and the EIDL, administered directly by the SBA. The Company had $253.1 million of PPP loans, principal amount outstanding (included in Commercial business above) as of December 31, 2020. In addition, the CARES Act provides that a financial institution may elect to suspend (1) the application of GAAP for certain loan modifications related to COVID-19 that would otherwise be categorized as a TDR and (2) any determination that such loan modifications would be considered a TDR, including the related impairment for accounting purposes. Accordingly, the Company had $532.4 million of loans with modifications related to COVID-19 during 2020, with $113.0 million still on deferral as of December 31, 2020. The Company elected to exclude AIR from the amortized cost basis of loans disclosed throughout this footnote. As of December 31, 2020 and December 31, 2019, AIR for loans totaled $13.6 million and $9.1 million, respectively, and is included in other assets on the Company’s consolidated statements of financial condition. The Company’s significant concentrations of credit risk in the loan portfolio relate to a geographic concentration in the communities that the Company serves. Certain executive officers, directors and their business interests are customers of the Company. Transactions with these parties are based on the same terms as similar transactions with unrelated third parties and do not carry more than normal credit risk. Borrowings by these related parties amounted to $32.8 million and $18.6 million at December 31, 2020 and 2019, respectively. During 2020, new borrowings amounted to $16.3 million (including borrowings of executive officers and directors that were outstanding at the time of their appointment), and repayments and other reductions were $2.1 million. Past Due Loans Aging The Company’s recorded investment, by loan class, in current and nonaccrual loans, as well as an analysis of accruing delinquent loans is set forth as of December 31 (in thousands): 30-59 Days Past Due 60-89 Days Past Due Greater Than 90 Days Total Past Due Nonaccrual Current Total Loans Nonaccrual with no allowance 2020 Commercial business $ 264 $ 87 $ - $ 351 $ 1,975 $ 796,083 $ 798,409 $ 1,502 Commercial mortgage 822 26 - 848 2,906 1,252,771 1,256,525 2,709 Residential real estate loans 984 60 - 1,044 2,587 582,906 586,537 2,587 Residential real estate lines 40 15 - 55 323 86,330 86,708 323 Consumer indirect 3,966 1,348 - 5,314 1,495 806,007 812,816 1,495 Other consumer 133 18 231 382 - 16,531 16,913 - Total loans, gross $ 6,209 $ 1,554 $ 231 $ 7,994 $ 9,286 $ 3,540,628 $ 3,557,908 $ 8,616 2019 Commercial business $ 361 $ - $ - $ 361 $ 1,177 $ 569,684 $ 571,222 Commercial mortgage 531 - - 531 3,146 1,104,638 1,108,315 Residential real estate loans 929 114 - 1,043 2,484 557,190 560,717 Residential real estate lines 231 37 - 268 102 100,678 101,048 Consumer indirect 3,729 1,019 - 4,748 1,725 815,706 822,179 Other consumer 116 8 6 130 - 15,854 15,984 Total loans, gross $ 5,897 $ 1,178 $ 6 $ 7,081 $ 8,634 $ 3,163,750 $ 3,179,465 There were no loans past due greater than 90 days and still accruing interest as of December 31, 2020 and 2019. There were $231 thousand and $6 thousand in consumer overdrafts which were past due greater than 90 days as of December 31, 2020 and 2019, respectively. Consumer overdrafts are overdrawn deposit accounts which have been reclassified as loans but by their terms do not accrue interest. (6.) LOANS (Continued) Interest income on nonaccrual loans, if recognized, is recorded using the cash basis method of accounting. There was no interest income recognized on nonaccrual loans during the years ended December 31, 2020, 2019 and 2018. For the years ended December 31, 2020, 2019 and 2018, estimated interest income of $430 thousand, $508 thousand, and $294 thousand, respectively, would have been recorded if all such loans had been accruing interest according to their original contractual terms. Troubled Debt Restructurings A modification of a loan constitutes a troubled debt restructuring (“TDR”) when a borrower is experiencing financial difficulty and the modification constitutes a concession. Commercial loans modified in a TDR may involve temporary interest-only payments, term extensions, reducing the interest rate for the remaining term of the loan, extending the maturity date at an interest rate lower than the current market rate for new debt with similar risk, collateral concessions, forgiveness of principal, forbearance agreements, or substituting or adding a new borrower or guarantor. There were no loans modified as a TDR during the years ended December 31, 2020 and 2019. There were no loans modified as a TDR during the years ended December 31, 2020 and 2019 that defaulted during the year ended December 31, 2020. For purposes of this disclosure, a loan modified as a TDR is considered to have defaulted when the borrower becomes 90 days Collateral Dependent Loans Management has determined that specific commercial loans on nonaccrual status, all loans that have had their terms restructured in a troubled debt restructuring and other loans deemed appropriate by management where repayment is expected to be provided substantially through the operation or sale of the collateral to be collateral dependent loans. Collateral dependent loans at December 31, 2020 included certain criticized COVID-19 bridge loans not otherwise classified as nonaccrual. The following table presents the amortized cost basis of collateral dependent loans by collateral type as of December 31, 2020 (in thousands): Collateral type Business assets Real property Total Specific Reserve December 31, 2020 Commercial business $ 2,379 $ — $ 2,379 $ 1,383 Commercial mortgage — 36,625 36,625 8,187 Total $ 2,379 $ 36,625 $ 39,004 $ 9,570 (6.) LOANS (Continued) Impaired Loans Prior to the adoption of ASC 326, management determined that specific commercial loans on nonaccrual status and all loans that have had their terms restructured in a troubled debt restructuring are impaired loans. The following table presents the recorded investment, unpaid principal balance and related allowance of impaired loans as well as average recorded investment and interest income recognized on impaired loans at December 31, 2019 (in thousands): Recorded Investment (1) Unpaid Principal Balance (1) Related Allowance Average Recorded Investment Interest Income Recognized 2019 With no related allowance recorded: Commercial business $ 563 $ 775 $ - $ 411 $ - Commercial mortgage 973 1,749 - 1,701 - 1,536 2,524 - 2,112 - With an allowance recorded: Commercial business 614 614 214 1,207 - Commercial mortgage 2,173 2,173 479 1,825 - 2,787 2,787 693 3,032 - $ 4,323 $ 5,311 $ 693 $ 5,144 $ - (1) Difference between recorded investment and unpaid principal balance represents partial charge-offs. Credit Quality Indicators The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors such as the fair value of collateral. The Company analyzes commercial business and commercial mortgage loans individually by classifying the loans as to credit risk. Risk ratings are updated any time the situation warrants. The Company uses the following definitions for risk ratings: Special Mention: Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the Company’s credit position at some future date. Substandard: Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Doubtful: Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. (6 .) LOANS (Continued) Loans that do not meet the criteria above that are analyzed individually as part of the process described above are considered “uncriticized” or pass-rated loans and are included in groups of homogeneous loans with similar risk and loss characteristics.

These loans are of higher risk and typically are made on the basis of the borrower’s ability to make repayment from the cash flow of the borrower’s business. Further, the collateral securing the loans may depreciate over time, may be difficult to appraise and may fluctuate in value. The credit risk related to commercial loans is largely influenced by general economic conditions, including the impact of the COVID-19 pandemic on small to mid-sized business in our market area, and the resulting impact on a borrower’s operations or on the value of underlying collateral, if any. Commercial mortgage loans generally have larger balances and involve a greater degree of risk than residential mortgage loans, potentially resulting in higher potential losses on an individual customer basis. Loan repayment is often dependent on the successful operation and management of the properties, as well as on the collateral securing the loan. Economic events, including the impact of the COVID-19 pandemic on the ability of the tenants to pay rent at these properties, or conditions in the real estate market could have an adverse impact on the cash flows generated by properties securing the Company’s commercial real estate loans and on the value of such properties. Residential real estate loans (comprised of conventional mortgages and home equity loans) and residential real estate lines (comprised of home equity lines) are generally made based on the borrower’s ability to make repayment from his or her employment and other income but are secured by real property whose value tends to be more easily ascertainable. Credit risk for these types of loans is generally influenced by general economic conditions, including the impact of the COVID-19 pandemic on the employment income of these borrowers, the characteristics of individual borrowers, and the nature of the loan collateral. Consumer indirect and other consumer loans may entail greater credit risk than residential mortgage loans and home equities, particularly in the case of other consumer loans which are unsecured or, in the case of indirect consumer loans, secured by depreciable assets, such as automobiles. In such cases, any repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment of the outstanding loan balance. In addition, consumer loan collections are dependent on the borrower’s continuing financial stability, and thus are more likely to be affected by adverse personal circumstances such as job loss, illness or personal bankruptcy, including the heightened risk that such circumstances may arise as a result of the COVID-19 pandemic. Furthermore, the application of various federal and state laws, including bankruptcy and insolvency laws, may limit the amount which can be recovered on such loans.

Goodwill And Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	(8.) GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill Goodwill is not amortized but, instead, is subject to impairment tests on at least an annual basis, and more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Company performs its annual impairment test of goodwill as of October 1 st Based on volatility in the capital markets and overall economic conditions as a result of the COVID‐19 pandemic accompanied by a decline in the Company’s stock price, a quantitative assessment was performed for the Banking reporting unit in the third quarter of 2020. Based on this quantitative assessment, the Company concluded that goodwill was not impaired. The Company completed a quantitative assessment in relation to the SDN reporting unit as of its 2020 annual test date and determined that goodwill was not impaired. The Company completed qualitative assessments in relation to the Courier Capital and the HNP Capital reporting units as of their 2020 annual test date and determined it was not more likely than not that the fair value of these reporting units were less than their carrying values. The results of the 2019 annual impairment tests for the Company’s reporting units indicated no goodwill impairment. The results of the 2018 annual impairment test for the SDN reporting unit resulted in a goodwill impairment charge of $2.4 million during the quarter ended December 31, 2018. The results of the 2018 annual impairment tests for the Banking, Courier Capital and HNP Capital reporting units indicated no goodwill impairment. Declines in the market value of the Company’s publicly traded stock price or declines in the Company’s ability to generate future cash flows may increase the potential that goodwill recorded on the Company’s consolidated statement of financial condition be designated as impaired and that the Company may incur a goodwill write-down in the future.

Debt Disclosure [Abstract]
Borrowings	(12.) The Company classifies borrowings as short-term or long-term in accordance with the original terms of the applicable agreement. Outstanding borrowings consisted of the following as of December 31 (in thousands): 2020 2019 Short-term borrowings: Short-term FHLB borrowings $ 5,300 $ 275,500 Long-term borrowings: Subordinated notes, net 73,623 39,273 Total borrowings $ 78,923 $ 314,773 Short-term borrowings Short-term FHLB borrowings have original maturities of less than one year and include overnight borrowings which we typically utilize to address short term funding needs as they arise. Short-term FHLB borrowings at December 31, 2020 consisted of $5.3 million in short-term borrowings. Short-term FHLB borrowings at December 31, 2019 consisted of $10.0 million in overnight borrowings and $265.5 million in short-term borrowings. The FHLB borrowings are collateralized by securities from the Company’s investment portfolio and certain qualifying loans. At December 31, 2020 and 2019, the Company’s borrowings had a weighted average rate of 1.70% and 1.88%, respectively. The Parent has a revolving line of credit with a commercial bank allowing borrowings up to $20.0 million in total as an additional source of working capital. At December 31, 2020 and 2019, no amounts have been drawn on the line of credit. (12.) (Continued) Long-term borrowings On October 7, 2020, the Company completed a private placement of $35.0 million in aggregate principal amount of fixed-to-floating rate subordinated notes due 2030 to qualified institutional buyers and accredited institutional investors that were subsequently exchanged for subordinated notes with substantially the same terms (the “2020 Notes”) registered under the Securities Act of 1933, as amended. The 2020 Notes have a maturity date of October 15, 2030 and bear interest, payable semi-annually, at the rate of 4.375% per annum, until October 15, 2025. Commencing on that date, the interest rate will reset quarterly to an interest rate per annum equal to the then current three-month secured overnight financing rate (“SOFR”) plus 4.265%, payable quarterly until maturity. Proceeds, net of debt issuance costs of $779 thousand, were $34.2 million. The net proceeds from this offering were used for general corporate purposes, including but not limited to, contribution of capital to the Bank to support both organic growth and regulatory capital ratios. The 2020 Notes qualify as Tier 2 capital for regulatory purposes. On April 15, 2015, the Company issued $40.0 million of 6.0% fixed to floating rate subordinated notes due April 15, 2030 (the “2015 Notes”) in a registered public offering. The 2015 Notes bear interest at a fixed rate of 6.0% per year, payable semi-annually, for the first 10 years. From April 15, 2025 to the April 15, 2030 maturity date, the interest rate will reset quarterly to an annual interest rate equal to the then current three-month London Interbank Offered Rate (LIBOR) plus 3.944%, payable quarterly. After the discontinuance of LIBOR, the interest rate will be determined by an alternate method as reasonably selected by the Company. The 2015 Notes are redeemable by the Company at any quarterly interest payment date beginning on April 15, 2025 to maturity at par, plus accrued and unpaid interest. Proceeds, net of debt issuance costs of $1.1 million, were $38.9 million. The net proceeds from this offering were used for general corporate purposes, including but not limited to, contribution of capital to the Bank to support both organic growth and opportunistic acquisitions. The 2015 Notes qualify as Tier 2 capital for regulatory purposes. The Company adopted ASU 2015-03 that requires debt issuance costs to be reported as a direct deduction from the face value of the 2015 Notes and the 2020 Notes, and not as a deferred charge. The debt issuance costs will be amortized as an adjustment to interest expense through April 15, 2025 for the 2015 Notes and through October 15, 2025 for the 2020 Notes.

Derivative Instruments and Hedg

Derivative Instruments and Hedging Activities	12 Months Ended

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	(13.) Risk Management Objective of Using Derivatives 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 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. Cash Flow Hedges of Interest Rate Risk The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate caps and interest rate swaps as part of its interest rate risk management strategy. Interest rate caps designated as cash flow hedges involve the receipt of variable amounts from a counterparty if interest rates rise above the strike rate on the contract in exchange for an up-front premium. During 2020, such derivatives were used to hedge the variable cash flows associated with short-term borrowings. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The Company is hedging its exposure to the variability in future cash flows for forecasted transactions over a period of approximately 60 months. As of December 31, 2020, the Company had one outstanding forward interest rate derivative with a notional value of $50.0 million that was designated as a cash flow hedge of interest rate risk. The derivative becomes effective in April 2022. (13.) (Continued) For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in accumulated other comprehensive income (loss) and subsequently reclassified into interest expense in the same period(s) during which the hedged transaction affects earnings. Amounts reported in accumulated other comprehensive income (loss) related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s borrowings. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. The Company’s cash flow hedge derivatives did not have any hedge ineffectiveness recognized in earnings during the years ended December 31, 2020 and 2019. During the next twelve months, the Company estimates that $114 thousand will be reclassified as an increase to interest expense. Interest Rate Swaps The Company executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. These interest rate swaps are simultaneously hedged by offsetting interest rate swaps that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate swaps associated with this program do not meet hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. Credit-risk-related Contingent Features The Company has agreements with certain of its derivative counterparties that contain one or more of the following provisions: (a) if the Company defaults on any of its indebtedness, including a default where repayment of the indebtedness has not been accelerated by the lender, the Company could also be declared in default on its derivative obligations, and (b) if the Company fails to maintain its status as a well-capitalized institution, the counterparty could terminate the derivative positions and the Company would be required to settle its obligations under the agreements. Mortgage Banking Derivatives The Company extends rate lock agreements to borrowers related to the origination of residential mortgage loans. To mitigate the interest rate risk inherent in these rate lock agreements when the Company intends to sell the related loan, once originated, as well as closed residential mortgage loans held for sale, the Company enters into forward commitments to sell individual residential mortgages. Rate lock agreements and forward commitments are considered derivatives and are recorded at fair value. (13.)

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	(14.) Financial Instruments with Off-Balance Sheet Risk The Company has financial instruments with off-balance sheet risk established 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 risk extending beyond amounts recognized in the financial statements. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is essentially the same as that involved with extending loans to customers. The Company uses the same credit underwriting policies in making commitments and conditional obligations as for on-balance sheet instruments. Off-balance sheet commitments as of December 31 consist of the following (in thousands): 2020 2019 Commitments to extend credit $ 1,012,810 $ 820,282 Standby letters of credit 22,393 21,911 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the agreement. Commitments generally have fixed expiration dates or other termination clauses which may require payment of a fee. Commitments may expire without being drawn upon; therefore, the total commitment amounts do not necessarily represent future cash requirements. Each customer’s creditworthiness is evaluated on a case-by-case basis. The amount of collateral obtained, if any, is based on management’s credit evaluation of the borrower. Standby letters of credit are conditional lending commitments issued by the Company to guarantee the performance of a customer to a third party. These standby letters of credit are primarily issued to support private borrowing arrangements. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loan facilities to customers. Unfunded Commitments At December 31, 2020 and December 31, 2019, the allowance for credit losses for unfunded commitments totaled $3.1 million and $0, respectively, and was included in other liabilities on the Company's consolidated statements of financial condition. For the year ended December 31, 2020 and 2019, credit loss expense for unfunded commitments was $1.0 million and $0, respectively, and was included in provision for credit losses on the Company’s consolidated statements of income. Contingent Liabilities and Litigation In the ordinary course of business there are various threatened and pending legal proceedings against the Company. Management believes that the aggregate liability, if any, arising from such litigation would not have a material adverse effect on the Company’s consolidated financial statements. We are party to an action filed against us on May 16, 2017 by Matthew L. Chipego, Charlene Mowry, Constance C. Churchill and Joseph W. Ewing in the Court of Common Pleas in Philadelphia, Pennsylvania. Plaintiffs seek class certification to represent classes of consumers in New York and Pennsylvania along with statutory damages, interest and declaratory relief. The plaintiffs seek to represent a putative class of consumers who are alleged to have obtained direct or indirect financing from us for the purchase of vehicles that we later repossessed. The plaintiffs specifically claim that the notices the Bank sent to defaulting consumers after their vehicles were repossessed did not comply with the relevant portions of the Uniform Commercial Code in New York and Pennsylvania. We dispute and believe we have meritorious defenses against these claims and plan to vigorously defend ourselves. In February 2020, we agreed to engage in mediation with the plaintiffs but mediation has not yet commenced. On October 19, 2020, the Court granted plaintiffs’ motion for judgment on the pleadings dismissing our affirmative defense against one named New York plaintiff that his claim was time-barred under New York law, applying a six-year (14.) If we settle these claims or the action is not resolved in our favor, we may suffer reputational damage and incur legal costs, settlements or judgments that exceed the amounts covered by our existing insurance policies. We can provide no assurances that our insurer will insure the legal costs, settlements or judgements we incur in excess of our deductible. If we are unsuccessful in defending ourselves from these claims or if our insurer does not insure us against legal costs we incur in excess of our deductible, the result may materially adversely affect our business, results of operations and financial condition.

Regulatory Matters [Abstract]
Regulatory Matters	(15.) General The supervision and regulation of financial and bank holding companies and their subsidiaries is intended primarily for the protection of depositors, the deposit insurance funds regulated by the FDIC and the banking system as a whole, and not for the protection of shareholders or creditors of bank holding companies. The various bank regulatory agencies have broad enforcement power over financial holding companies and banks, including the power to impose substantial fines, operational restrictions and other penalties for violations of laws and regulations and for safety and soundness considerations. Capital Banks and bank holding companies are subject to various regulatory capital requirements administered by state and federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk weighting and other factors. The Basel III Capital Rules, a new comprehensive capital framework for U.S. banking organizations, became effective for the Company and the Bank on January 1, 2015 (subject to a phase-in period for certain provisions). Quantitative measures established by the Basel III Capital Rules to ensure capital adequacy require the maintenance of minimum amounts and ratios (set forth in the table that follows) of Common Equity Tier 1 capital (“CET1”), Tier 1 capital and Total capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital to adjusted quarterly average assets (as defined). The Economic Growth Act provided for a potential exception from the Basel III Rules for community banks that maintain a Community Bank Leverage Ratio (“CBLR”) of at least 8.0% to 10.0%. The CBLR is calculated by dividing Tier 1 capital by the bank’s average total consolidated assets. In the final rules approved by the FDIC in September 2019, qualifying community banking organizations that opt in to using the CBLR are considered to be in compliance with the Basel III Rules as long as the bank maintains a CBLR of greater than 9.0%. If a bank is not a qualifying community banking organization, does not opt in to using the CBLR, or cannot maintain a CBLR of greater than 9.0%, the bank would have to comply with the Basel III Rules. We are currently evaluating the CBLR framework and the potential impact CBLR adoption would have on the Company and the Bank, respectively. The Company’s and the Bank’s Common Equity Tier 1 capital includes common stock and related paid-in capital, net of treasury stock, and retained earnings. In connection with the adoption of the Basel III Capital Rules, we elected to opt-out of the requirement to include most components of accumulated other comprehensive income in Common Equity Tier 1. Common Equity Tier 1 for both the Company and the Bank is reduced by goodwill and other intangible assets, net of associated deferred tax liabilities, and subject to transition provisions. Tier 1 capital includes Common Equity Tier 1 capital and additional Tier 1 capital. For the Company, additional Tier 1 capital at December 31, 2020 includes, subject to limitation, $17.3 million of preferred stock. Total capital includes Tier 1 capital and Tier 2 capital. Tier 2 capital for both the Company and the Bank includes a permissible portion of the allowance for credit losses. Tier 2 capital for the Company also includes qualified subordinated debt. At December 31, 2020, the Company’s Tier 2 capital included $73.6 million of Subordinated Notes. The Common Equity Tier 1, Tier 1 and Total capital ratios are calculated by dividing the respective capital amounts by risk-weighted assets. Risk-weighted assets are calculated based on regulatory requirements and include total assets, with certain exclusions, allocated by risk weight category, and certain off-balance-sheet items, among other things. The leverage ratio is calculated by dividing Tier 1 capital by adjusted quarterly average total assets, which exclude goodwill and other intangible assets, among other things. (15.) The Basel III Capital Rules became fully phased in on January 1, 2019 and require the Company and the Bank to maintain (i) a minimum ratio of Common Equity Tier 1 capital to risk-weighted assets of at least 4.5%, plus a 2.5% “capital conservation buffer” (which is added to the 4.5% Common Equity Tier 1 capital ratio as that buffer was phased in, effectively resulting in a minimum ratio of Common Equity Tier 1 capital to risk-weighted assets of at least 7.0% upon full implementation), (ii) a minimum ratio of Tier 1 capital to risk-weighted assets of at least 6.0%, plus the capital conservation buffer (which is added to the 6.0% Tier 1 capital ratio as that buffer was phased in, effectively resulting in a minimum Tier 1 capital ratio of 8.5% upon full implementation), (iii) a minimum ratio of Total capital (that is, Tier 1 plus Tier 2) to risk-weighted assets of at least 8.0%, plus the capital conservation buffer (which is added to the 8.0% total capital ratio as that buffer was phased in, effectively resulting in a minimum total capital ratio of 10.5% upon full implementation) and (iv) a minimum leverage ratio of 4.0%, calculated as the ratio of Tier 1 capital to average quarterly assets. The implementation of the capital conservation buffer began on January 1, 2016 at the 0.625% level and was phased in over a four-year period (increasing by that amount on each subsequent January 1, until it reached 2.5% on January 1, 2019). The Basel III Capital Rules also provide for a “countercyclical capital buffer” that is applicable to only certain covered institutions and does not have any current applicability to the Company or the Bank. The capital conservation buffer is designed to absorb losses during periods of economic stress and, as detailed above, effectively increases the minimum required risk-weighted capital ratios. Banking institutions with a ratio of Common Equity Tier 1 capital to risk-weighted assets below the effective minimum (4.5% plus the capital conservation buffer and, if applicable, the countercyclical capital buffer) will face constraints on dividends, equity repurchases and compensation based on the amount of the shortfall. (15.) (Continued) The following table presents actual and required capital ratios as of December 31, 2020 and 2019 for the Company and the Bank under the Basel III Capital Rules. The minimum required capital amounts presented include the minimum required capital levels as of December 31, 2019 based on the phase-in provisions of the Basel III Capital Rules and the minimum required capital levels as of January 1, 2019 when the Basel III Capital Rules have been fully phased-in. Capital levels required to be considered well capitalized are based upon prompt corrective action regulations, as amended to reflect the changes under the Basel III Capital Rules (in thousands): Actual Minimum Capital Required – Basel III Required to be Considered Well Capitalized Amount Ratio Amount Ratio Amount Ratio 2020 Tier 1 leverage: Company $ 407,061 8.25 % $ 197,344 4.00 % $ 246,680 5.00 % Bank 441,929 8.97 197,064 4.00 246,330 5.00 CET1 capital: Company 389,733 10.18 268,010 7.00 248,866 6.50 Bank 441,929 11.57 267,387 7.00 248,288 6.50 Tier 1 capital: Company 407,061 10.63 325,441 8.50 306,297 8.00 Bank 441,929 11.57 324,684 8.50 305,585 8.00 Total capital: Company 521,193 13.61 402,015 10.50 382,871 10.00 Bank 482,439 12.63 401,080 10.50 381,981 10.00 2019 Tier 1 leverage: Company $ 381,473 9.00 % $ 169,504 4.00 % $ 211,880 5.00 % Bank 409,031 9.67 169,189 4.00 211,486 5.00 CET1 capital: Company 364,145 10.31 247,330 7.00 229,663 6.50 Bank 409,031 11.61 246,674 7.00 229,055 6.50 Tier 1 capital: Company 381,473 10.80 300,329 8.50 282,663 8.00 Bank 409,031 11.61 299,533 8.50 281,914 8.00 Total capital: Company 451,228 12.77 370,995 10.50 353,328 10.00 Bank 439,514 12.47 370,011 10.50 352,392 10.00 As of December 31, 2020 and 2019, the Company and Bank were considered “well capitalized” under all regulatory capital guidelines. Such determination has been made based on the Tier 1 leverage, CET1 capital, Tier 1 capital and total capital ratios. Federal Reserve Requirements The Bank is required to maintain cash on hand or on deposit at the FRB of New York. As of December 31, 2020, the Bank was not required to maintain a reserve balance at the FRB of New York. The reserve requirement for the Bank totaled $6.4 million as of December 31, 2019. Dividend Restrictions In the ordinary course of business, the Company is dependent upon dividends from the Bank to provide funds for the payment of dividends to shareholders and to provide for other cash requirements. Banking regulations may limit the amount of dividends that may be paid. Approval by regulatory authorities is required if the effect of dividends declared would cause the regulatory capital of the Bank to fall below specified minimum levels. Approval is also required if dividends declared exceed the net profits for that year combined with the retained net profits for the preceding two years.

Share-Based Compensation

Share-Based Compensation	12 Months Ended
	Dec. 31, 2020
Share Based Compensation [Abstract]
Share-Based Compensation	(18.) The Company maintains certain stock-based compensation plans, approved by the Company’s shareholders, that are administered by the Management Development and Compensation Committee (the “Compensation Committee”) of the Board. In May 2015, the Company’s shareholders approved the 2015 Long-Term Incentive Plan (the “2015 Plan”) to replace the 2009 Management Stock Incentive Plan and the 2009 Directors’ Stock Incentive Plan (collectively, the “2009 Plans”). A total of 438,076 shares transferred from the 2009 Plans were available for grant pursuant to the 2015 Plan. In addition, any shares subject to outstanding awards under the 2009 Plans that are canceled, expired, forfeited or otherwise not issued or are settled in cash will become available for future award grants under the 2015 Plan. As of December 31, 2020, there were approximately 156,000 shares available for grant under the 2015 Plan. Under the Plan, the Compensation Committee may establish and prescribe grant guidelines including various terms and conditions for the granting of stock-based compensation. For stock options, the exercise price of each option equals the market price of the Company’s stock on the date of the grant. All options expire after a period of ten years from the date of grant and generally become fully exercisable over a period of 3 to 5 years from the grant date. When an option recipient exercises their options, the Company issues shares from treasury stock and records the proceeds as additions to capital. Shares of restricted stock granted to employees generally vest over 2 to 3 years from the grant date. Fifty percent of the shares of restricted stock granted to non-employee directors generally vests on the date of grant and the remaining fifty percent generally vests one year from the grant date. Vesting of the shares may be based on years of service, established performance measures or both. If restricted stock grants are forfeited before they vest, the shares are reacquired into treasury stock. Restricted stock units granted to employees generally fully vest on the third anniversary of the date of grant. The share-based compensation plans were established to allow for the granting of compensation awards to attract, motivate and retain employees, executive officers and non-employee directors who contribute to the long-term growth and profitability of the Company and to give such persons a proprietary interest in the Company, thereby enhancing their personal interest in the Company’s success. (18.) SHARE-BASED COMPENSATION (Continued) The Company awarded grants of restricted stock units to certain members of management during the year ended December 31, 2020. Fifty percent of the shares subject to each grant that ultimately vest are contingent on achieving specified return on average equity (“ROAE”) targets relative to the SNL Small Cap Bank & Thrift Index, a market index the Management Development & Compensation Committee has selected as a peer group for this purpose. These shares will be earned based on the Company’s achievement of a relative ROAE performance requirement, on a percentile basis, compared to the SNL Small Cap Bank & Thrift Index over a three-year three-year The grant-date fair values for both the ROAE and the ROAA portions of PSUs granted during the year ended December 31, 2020 are equal to the closing market price of our common stock on the date of grant reduced by the present value of the dividends expected to be paid on the underlying shares. The Company granted three-year During the year ended December 31, 2020, the Company granted a total of 12,798 restricted shares of common stock to non-employee directors, of which 6,399 shares vested immediately and 6,399 shares will vest after completion of a one-year The Company awarded grants of restricted stock units to certain members of management during the year ended December 31, 2019. Fifty percent of the shares subject to each grant will be earned upon achievement of an ROAA performance requirement for the Company’s fiscal year ending December 31, 2021. The remaining fifty percent of the shares will be earned based on the Company’s achievement of a relative total shareholder return (“TSR”) performance requirement, on a percentile basis, compared to the SNL Small Cap Bank & Thrifts Index over a three-year The grant-date fair value of the TSR performance award granted on February 26, 2019 was determined using the Monte Carlo simulation model on the date of grant, assuming the following (i) expected term of 2.84 years, (ii) risk free interest rate of 2.43%, (iii) expected dividend yield of 3.20% and (iv) expected stock price volatility over the expected term of the TSR performance award of 21.3%. The grant-date fair value of the TSR performance award granted on May 22, 2019 was determined using the Monte Carlo simulation model on the date of grant, assuming the following (i) expected term of 2.61 years, (ii) risk free interest rate of 2.18%, (iii) expected dividend yield of 3.60% and (iv) expected stock price volatility over the expected term of the TSR performance award of 22.0%. The grant-date fair value of all other restricted stock awards is equal to the closing market price of the Company’s common stock on the date of grant. The Company granted additional restricted stock units to management during the year ended December 31, 2019. These awards will vest after completion of a three-year During the year ended December 31, 2019, the Company granted a total of 8,226 restricted shares of common stock to non-employee directors, of which 4,113 shares vested immediately and 4,113 shares will vest after completion of a one-year (18.) SHARE-BASED COMPENSATION (Continued) The Company awarded grants of restricted stock units to certain members of management during the year ended December 31, 2018. The awards will be earned based on the Company’s achievement of a TSR performance requirement, on a percentile basis, compared to the SNL Small Cap Bank & Thrifts Index over a one-year The grant-date fair value of the TSR performance award granted during the year ended December 31, 2018 was determined using the Monte Carlo simulation model on the date of grant, assuming the following (i) expected term of 2.84 years, (ii) risk free interest rate of 2.39%, (iii) expected dividend yield of 2.83% and (iv) expected stock price volatility over the expected term of the TSR performance award of 21.2%. The grant-date fair value of all other restricted stock awards is equal to the closing market price of the Company’s common stock on the date of grant. The Company granted additional restricted stock units to management during the year ended December 31, 2018. These awards will vest after completion of a three-year During the year ended December 31, 2018, the Company granted a total of 7,370 restricted shares of common stock to non-employee directors, of which 3,690 shares vested immediately and 3,680 shares will vest after completion of a one-year The restricted stock awards granted to the directors and the restricted stock units granted to management in 2020, 2019 and 2018 do not have rights to dividends or dividend equivalents. The Company uses the Black-Scholes valuation method to estimate the fair value of its stock option awards. There were no stock options awarded during 2020, 2019 or 2018. There was no unrecognized compensation expense related to unvested stock options as of December 31, 2020. There was no stock option activity for the year ended December 31, 2020. The aggregate intrinsic value (the amount by which the market price of the stock on the date of exercise exceeded the market price of the stock on the date of grant) of option exercises for the years ended December 31, 2018 was $236 thousand. The total cash received as a result of option exercises under stock compensation plans for the years ended December 31, 2018 was $320 thousand. The tax benefits realized in connection with these stock option exercises were not significant. The following is a summary of restricted stock award and restricted stock units activity for the year ended December 31, 2020: Weighted Average Market Number of Price at Shares Grant Date Outstanding at beginning of year 151,808 $ 27.80 Granted 94,906 24.36 Vested (35,433 ) 28.84 Forfeited (42,768 ) 27.78 Outstanding at end of period 168,513 $ 25.65 As of December 31, 2020, there was $2.0 million of unrecognized compensation expense related to unvested restricted stock awards and restricted stock units that is expected to be recognized over a weighted average period of 1.8 years. (18.) SHARE-BASED COMPENSATION (Continued) The Company amortizes the expense related to share-based compensation over the vesting period. Share-based compensation expense is recorded as a component of salaries and employee benefits in the consolidated statements of income for awards granted to management and as a component of other noninterest expense for awards granted to directors. The share-based compensation expense included in the statements on income for the years ended December 31 was as follows (in thousands): 2020 2019 2018 Salaries and employee benefits $ 1,107 $ 1,175 $ 1,045 Other noninterest expense 226 231 256 Total share-based compensation expense $ 1,333 $ 1,406 $ 1,301

Income Taxes	(19.) The income tax expense for the years ended December 31 consisted of the following (in thousands): 2020 2019 2018 Current tax expense (benefit): Federal $ 10,041 $ 8,882 $ 19,351 State 1,873 1,308 1,135 Total current tax expense (benefit) 11,914 10,190 20,486 Deferred tax expense (benefit): Federal (3,306 ) 280 (10,303 ) State (1,217 ) 89 (177 ) Total deferred tax expense (benefit) (4,523 ) 369 (10,480 ) Total income tax expense $ 7,391 $ 10,559 $ 10,006 Income tax expense differed from the statutory federal income tax rate for the years ended December 31 as follows: 2020 2019 2018 Statutory federal tax rate 21.0 % 21.0 % 21.0 % Increase (decrease) resulting from: Tax exempt interest income (2.0 ) (1.9 ) (2.6 ) Tax credits and adjustments (3.4 ) (3.0 ) (0.3 ) Non-taxable earnings on company owned life insurance (0.9 ) (0.6 ) (0.8 ) State taxes, net of federal tax benefit 1.1 1.9 1.5 Nondeductible expenses 0.1 0.2 0.2 Goodwill and contingent consideration adjustments - - 1.0 Other, net 0.3 0.2 0.2 Effective tax rate 16.2 % 17.8 % 20.2 % Total income tax expense (benefit) was as follows for the years ended December 31 (in thousands): 2020 2019 2018 Income tax expense $ 7,391 $ 10,559 $ 10,006 Shareholder’s equity 5,732 3,113 (3,156 ) (19.) (Continued) The Company recognizes deferred income taxes for the estimated future tax effects of differences between the tax and financial statement bases of assets and liabilities considering enacted tax laws. These differences result in deferred tax assets and liabilities, which are included in other assets in the Company’s consolidated statements of financial condition. The Company also assesses the likelihood that deferred tax assets will be realizable based on, among other considerations, future taxable income and establishes, if necessary, a valuation allowance for those deferred tax assets determined to not likely be realizable. A deferred tax asset valuation allowance is recognized if, based on the weight of available evidence (both positive and negative), it is more likely than not that some portion or all of the deferred tax assets will not be realized. The future realization of deferred tax benefits depends upon the existence of sufficient taxable income within the carry-back and carry-forward periods. Management’s judgment is required in determining the appropriate recognition of deferred tax assets and liabilities, including projections of future taxable income. In 2020 and 2019, the Company recognized the impact of its investments in partnerships that placed property in service during both years, which generated tax credits due to qualifying expenses. At the time that a structure is placed into service, the Company is eligible for federal and New York State tax credits. See Note 1 for the Company’s accounting policy for income taxes and these tax credit investments. The Company’s net deferred tax asset is included in other assets in the consolidated statements of financial condition. The tax effects of temporary differences that give rise to the deferred tax assets and deferred tax liabilities are as follows at December 31 (in thousands): 2020 2019 Deferred tax assets: Allowance for credit losses $ 14,239 $ 7,810 Leases - right of use obligations 5,510 5,474 Deferred compensation 1,149 1,095 Investment in limited partnerships 1,418 1,191 SERP agreements 323 418 Interest on nonaccrual loans 88 191 Share-based compensation 602 586 Other 148 224 Gross deferred tax assets 23,477 16,989 Deferred tax liabilities: Leases - right of use assets 5,113 5,474 Prepaid expenses 635 498 Prepaid pension costs 1,183 897 Intangible assets 2,286 2,643 Depreciation and amortization 2,046 1,961 Net unrealized gain on securities available for sale 5,079 301 Loan servicing assets 338 289 Other 627 550 Gross deferred tax liabilities 17,307 12,613 Net deferred tax asset $ 6,170 $ 4,376 On December 22, 2017, the TCJ Act was signed into law which, among other items, reduces the federal statutory corporate tax rate from 35 percent to 21 percent, effective January 1, 2018. The TCJ Act also contains other provisions that may affect the Company currently or in future years. Among these are changes to the deductibility of meals and entertainment, the deductibility of executive compensation, accelerated expensing of depreciable property for assets placed into service after September 27, 2017 and before 2023, limits on the deductibility of net interest expense, elimination of the corporate alternative minimum tax, limits on net operating loss carryforwards to 80% of taxable income, among other provisions. (19.) (Continued) Based upon the Company’s historical and projected future levels of pre-tax and taxable income, the scheduled reversals of taxable temporary differences to offset future deductible amounts, and prudent and feasible tax planning strategies, management believes it is more likely than not that the deferred tax assets will be realized. As such, no valuation allowance has been recorded as of December 31, 2020 or 2019. The Company and its subsidiaries are primarily subject to federal and New York income taxes. The federal income tax years currently open for audits are 2017 through 2020. The New York income tax years currently open for audits are 2018 through 2020. At December 31, 2020, the Company had no federal or New York net operating loss or tax credits carryforwards. The Company’s unrecognized tax benefits and changes in unrecognized tax benefits were not significant as of or for the years ended December 31, 2020, 2019 and 2018. There were no material interest or penalties recorded in the income statement in income tax expense for the years ended December 31, 2020, 2019 and 2018. As of December 31, 2020 and 2019, there were no amounts accrued for interest or penalties related to uncertain tax positions.

Compensation And Retirement Disclosure [Abstract]
Employee Benefit Plans	(21.) Supplemental Executive Retirement Agreements The Company has non-qualified Supplemental Executive Retirement Agreements (“SERPs”) covering certain former executives. The unfunded liability related to the SERPs was $1.3 million and $1.7 million at December 31, 2020 and 2019, respectively. SERP expense was $51 thousand, $366 thousand and $215 thousand for 2020, 2019 and 2018, respectively. Defined Contribution Plan Employees that meet specified eligibility conditions are eligible to participate in the Company sponsored 401(k) plan. Under the plan, participants may make contributions, in the form of salary deferrals, up to the maximum Internal Revenue Code limit. The Company is also permitted to make additional discretionary contributions, although no such additional discretionary contributions were made in 2020, 2019 or 2018. Defined Benefit Pension Plan The Company participates in The New York State Bankers Retirement System (the “Plan”), a defined benefit pension plan covering substantially all employees. For employees hired prior to December 31, 2006, who met participation requirements on or before January 1, 2008 (“Tier 1 Participant”), the benefits are generally based on years of service and the employee’s highest average compensation during five consecutive years of employment. Effective January 1, 2016, the Plan was amended to open the Plan to eligible employees who were hired on and after January 1, 2007 (“Tier 2 Participant”) and provide these eligible participants with a cash balance benefit formula. The following table provides a reconciliation of the Company’s changes in the Plan’s benefit obligations, fair value of assets and a statement of the funded status as of and for the year ended December 31 (in thousands): 2020 2019 Change in projected benefit obligation: Projected benefit obligation at beginning of period $ 84,328 $ 69,574 Service cost 3,693 3,207 Interest cost 2,537 2,777 Actuarial (gain) loss 11,154 11,993 Benefits paid and plan expenses (4,152 ) (3,223 ) Projected benefit obligation at end of period 97,560 84,328 Change in plan assets: Fair value of plan assets at beginning of period 87,827 75,188 Actual return on plan assets 18,501 15,862 Employer contributions - - Benefits paid and plan expenses (4,152 ) (3,223 ) Fair value of plan assets at end of period 102,176 87,827 Funded status at end of period $ 4,616 $ 3,499 The accumulated benefit obligation was $88.9 million and $76.8 million at December 31, 2020 and 2019, respectively. The Company’s funding policy is to contribute, at a minimum, an actuarially determined amount that will satisfy the minimum funding requirements determined under the appropriate sections of Internal Revenue Code. The Company has no minimum required contribution for the 2021 fiscal year. (21.) (Continued) Estimated benefit payments under the Plan over the next ten years at December 31, 2020 are as follows (in thousands): 2021 $ 4,581 2022 3,860 2023 4,213 2024 4,259 2025 4,472 2026 - 2030 25,042 Net periodic pension cost consists of the following components for the years ended December 31 (in thousands): 2020 2019 2018 Service cost $ 3,693 $ 3,207 $ 3,346 Interest cost on projected benefit obligation 2,537 2,777 2,387 Expected return on plan assets (5,136 ) (4,736 ) (5,284 ) Amortization of unrecognized loss 1,270 1,445 725 Amortization of unrecognized prior service (credit) cost - - (5 ) Net periodic pension cost $ 2,364 $ 2,693 $ 1,169 The actuarial assumptions used to determine the net periodic pension cost were as follows: 2020 2019 2018 Weighted average discount rate 3.09 % 4.13 % 3.49 % Rate of compensation increase 3.00 % 3.00 % 3.00 % Expected long-term rate of return 6.00 % 6.50 % 6.50 % The actuarial assumptions used to determine the projected benefit obligation were as follows: 2020 2019 2018 Weighted average discount rate 2.32 % 3.09 % 4.13 % Rate of compensation increase 3.00 % 3.00 % 3.00 % The weighted average discount rate was based upon the projected benefit cash flows and the market yields of high grade corporate bonds that are available to pay such cash flows. The Plan’s overall investment strategy is to invest in a diversified portfolio while managing the variability between the assets and projected liabilities of underfunded pension plans. The Plan’s Board Members approved a migration (the “Migration”) of substantially all of the Plan’s assets to one fund, Commingled Pensions Trust Fund (LDI Diversified Balanced) of JPMorgan Chase Bank, N.A. (“JPMCB LDI Diversified Balanced Fund” or the “Fund”). The Fund is a collective investment fund managed by the Plan’s trustee (the “Trustee”) under the Declaration of Trust. The Trustee is the Fund’s manager and makes day-to-day investment decisions for the Fund. The Fund is a group trust within the meaning of Internal Revenue Service Revenue Ruling 81-100, as amended. In reliance upon exemptions from the registration requirements of the federal securities laws, neither the Fund nor the Fund’s Units are registered with the SEC or any state securities commission. Because the Fund is not subject to registration under federal or state securities laws, certain protections that might otherwise be provided to investors in registered funds are not available to investors in the Fund. However, as a bank-sponsored collective investment trust holding qualified retirement plan assets, the Fund is required to comply with applicable provisions of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and the Trustee is subject to supervision and regulation by the Office of the Comptroller of the Currency and the Department of Labor. (21.) EMPLOYEE BENEFIT PLANS (Continued) Prior to the Migration, the Plan’s overall investment strategy was to achieve a mix of approximately 97% of investments for long-term growth and 3% for near-term benefit payments with a wide diversification of asset types, fund strategies, and fund managers. The Board made the election in their December 2018 meeting and the Migration had an effective trade date of February 28, 2019. The Fund employs a liability driven investing (“LDI”) strategy for pension plans that are seeking a solution that is balanced between growth and hedging. The Bloomberg Barclays Long A U.S. Corporate Index, the Fund’s primary liability-performance benchmark, is used as a proxy for plan projected liabilities. The growth-oriented portion of the Fund invests in a mix of asset classes that the Fund’s Trustee believes will collectively maximize total risk-adjusted return through a combination of capital appreciation and income. This portion of the Fund will comprise between 35% and 90% of the portfolio and will invest directly or indirectly via underlying funds in a broad mix of global equity, credit, global fixed income, real estate and cash-plus strategies. The remaining portion of the Fund, between 10% and 65% of the portfolio, provides exposure to U.S. long duration fixed income and is used to minimize volatility relative to a plan’s projected liabilities. This portion of the Fund will invest directly or indirectly via underlying funds in investment grade corporate bonds and securities issued by the U.S. Treasury and its agencies or instrumentalities. The following table represents the Plan’s target asset allocation and actual asset allocation, respectively, as of December 31, 2020 and 2019: 2020 2019 Target Actual Target Actual Allocation Allocation Allocation Allocation Asset category: Cash and cash equivalents 0.00 % 0.00 % 0.00 % 0.00 % Equity securities 28.25 31.56 28.25 31.75 Fixed income securities 59.75 62.60 59.75 57.65 Alternative investments 12.00 5.84 12.00 10.60 Cash equivalents include repurchase agreements, banker’s acceptances, commercial paper, negotiable certificates of deposit, U.S. government securities with less than one year to maturity and funds (including the Commingled Pension Trust Fund (Liquidity) of JPMorgan Chase Bank, N.A. (“JPMorgan”)) established to invest in these types of highly liquid, high quality instruments. Equity securities primarily include investments in common stocks, depository receipts, preferred stocks, commingled pension trust funds, exchange traded funds and real estate investment trusts. Fixed income securities include corporate bonds, government issues, credit card receivables, mortgage backed securities, municipals, commingled pension trust funds and other asset backed securities. Alternative investments are real estate interests and related investments held within a commingled pension trust fund. The Fund is valued utilizing the valuation policies set forth by JP Morgan’s asset management committee. Underlying investments for which market quotations are readily available are valued at their market value. Underlying investments for which market quotations are not readily available are fair valued by approved affiliated and/or unaffiliated pricing vendors, third-party broker-dealers or methodologies as approved by the asset management committee. Fixed income instruments are valued based on prices received from approved affiliated and unaffiliated pricing vendors or third-party broker-dealers (collectively referred to as “Pricing Services”). The Pricing Services use multiple valuation techniques to determine the valuation of fixed income instruments. In instances where sufficient market activity exists, the Pricing Services may utilize a market-based approach through which trades or quotes from market makers are used to determine the valuation of these instruments. In instances where sufficient market activity may not exist, the Pricing Services also utilize proprietary valuation models which may consider market transactions in comparable securities and the various relationships between securities in determining fair value and/or market characteristics in order to estimate the relevant cash flows, which are then discounted to calculate the fair values. Equities and other exchange-traded instruments are valued at the last sales price or official market closing price on the primary exchange on which the instrument is traded before the net asset values (“NAV”) of the Funds are calculated on a valuation date. Futures contracts are generally valued on the basis of available market quotations. Forward foreign currency exchange contracts are valued utilizing market quotations from approved Pricing Services. The Fund invests in the Commingled Pension Trust Fund (“Strategic Property Fund”) of JPMorgan (the “SPF”), which holds significant amounts of investments which have been fair valued at December 31, 2020 and 2019. During the years ended December 31, 2020 and 2019, there were no transfers in or out of Levels 1, 2 or 3. In addition, there were no changes in valuation methodologies during the years ended December 31, 2020 and 2019. Prior to the Migration, the Plan had a direct investment in the SPF, which was a Level 3 investment. (21.) (Continued) The following is a table of the pricing methodology and unobservable inputs for Level 3 investments held during the year ended December 31, 2019 used by JPMorgan in pricing commingled pension trust funds (“CPTF”): Principal Valuation Technique(s) Used Unobservable Inputs CPTF – Other: CPTF (Strategic Property) of JPMorgan Market, Income Approach, Debt Service and Sales Comparison Credit Spreads, Discount Rate, Loan to Value Ratio, Terminal Capitalization Rate and Value per Square Foot The major categories of Plan assets measured at fair value on a recurring basis as of December 31 are presented in the following tables (in thousands).

(Continued) Postretirement Benefit Plan An entity acquired by the Company provided health and dental care benefits to retired employees who met specified age and service requirements through a postretirement health and dental care plan in which both the acquired entity and the retirees shared the cost. The plan provided for substantially the same medical insurance coverage as for active employees until their death and was integrated with Medicare for those retirees aged 65 or older. In 2001, the plan’s eligibility requirements were amended to curtail eligible benefit payments to only retired employees and active employees who had already met the then-applicable age and service requirements under the Plan. In 2003, retirees under age 65 began contributing to health coverage at the same cost-sharing level as that of active employees. Retirees ages 65 or older were offered new Medicare supplemental plans as alternatives to the plan historically offered. The cost sharing of medical coverage was standardized throughout the group of retirees aged 65 or older. In addition, to be consistent with the administration of the Company’s dental plan for active employees, all retirees who continued dental coverage began paying the full monthly premium. The accrued liability included in other liabilities in the consolidated statements of financial condition related to this plan amounted to $108 thousand and $110 thousand as of December 31, 2020 and 2019, respectively. The postretirement expense for the plan that was included in salaries and employee benefits in the consolidated statements of income was not significant for the years ended December 31, 2020, 2019 and 2018. The plan is not funded. The components of accumulated other comprehensive loss related to the defined benefit plan and postretirement benefit plan as of December 31 are summarized below (in thousands): 2020 2019 Defined benefit plan: Net actuarial loss $ (16,412 ) $ (19,894 ) Prior service credit (cost) - - (16,412 ) (19,894 ) Postretirement benefit plan: Net actuarial loss (127 ) (133 ) Prior service credit 3 37 (124 ) (96 ) Total (16,536 ) (19,990 ) Deferred tax benefit 4,237 5,122 Amounts included in accumulated other comprehensive loss $ (12,299 ) $ (14,868 ) Changes in plan assets and benefit obligations recognized in other comprehensive income on a pre-tax basis during the years ended December 31 are as follows (in thousands): 2020 2019 Defined benefit plan: Net actuarial gain (loss) $ 2,212 $ (867 ) Amortization of net loss 1,270 1,445 Amortization of prior service credit - - 3,482 578 Postretirement benefit plan: Net actuarial (loss) gain (12 ) (12 ) Amortization of net loss 18 18 Amortization of prior service credit (34 ) (65 ) (28 ) (59 ) Total recognized in other comprehensive income $ 3,454 $ 519

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	(22.) Determination of Fair Value – Assets Measured at Fair Value on a Recurring and Nonrecurring Basis Valuation Hierarchy The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. ASC Topic 820, “Fair Value Measurements and Disclosures,” establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. There have been no changes in the valuation techniques used during the current period. The fair value hierarchy is as follows: • Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. • Level 2 - Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means. • Level 3 - Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities. Transfers between levels of the fair value hierarchy are recorded as of the end of the reporting period. 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 and the company’s creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. The Company’s 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. Furthermore, the reported fair value amounts have not been comprehensively revalued since the presentation dates, and therefore, estimates of fair value after the balance sheet date may differ significantly from the amounts presented herein. A more detailed description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. Securities available for sale: Securities classified as available for sale are reported at fair value utilizing Level 2 inputs. For these securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements 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. Derivative instruments: The fair value of derivative instruments is determined using quoted secondary market prices for similar financial instruments and are classified as Level 2 in the fair value hierarchy. Loans held for sale: The fair value of loans held for sale is determined using quoted secondary market prices and investor commitments. Loans held for sale are classified as Level 2 in the fair value hierarchy. (2 2 .) FAIR VALUE MEASUREMENTS (Continued) Collateral dependent loans: Fair value of collateral dependent loans with specific allocations of the allowance for credit losses - loans is measured based on the value of the collateral securing these loans and is classified as Level 3 in the fair value hierarchy. Collateral may be real estate and/or business assets including equipment, inventory and/or accounts receivable and collateral value is determined based on appraisals performed by qualified licensed appraisers hired by the Company. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Appraised and reported values may be discounted based on management’s historical knowledge, changes in market conditions from the time of valuation, and/or management’s expertise and knowledge of the client and the client’s business. Such discounts are typically significant and result in a Level 3 classification of the inputs for determining fair value. Collateral dependent loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly, based on the same factors identified above. Loan servicing rights: Loan servicing rights do not trade in an active market with readily observable market data. As a result, the Company estimates the fair value of loan servicing rights by using a discounted cash flow model to calculate the present value of estimated future net servicing income. The assumptions used in the discounted cash flow model are those that we believe market participants would use in estimating future net servicing income, including estimates of loan prepayment rates, servicing costs, ancillary income, impound account balances, and discount rates. The significant unobservable inputs used in the fair value measurement of the Company’s loan servicing rights are the constant prepayment rates and weighted average discount rate. Significant increases (decreases) in any of those inputs in isolation could result in a significantly lower (higher) fair value measurement. Although the constant prepayment rate and the discount rate are not directly interrelated, they will generally move in opposite directions. Loan servicing rights are classified as Level 3 measurements due to the use of significant unobservable inputs, as well as significant management judgment and estimation. Other real estate owned (foreclosed assets): Nonrecurring adjustments to certain commercial and residential real estate properties classified as other real estate owned are measured at the lower of carrying amount or fair value, less costs to sell. Fair values are generally based on third party appraisals of the property, resulting in a Level 3 classification. The appraisals are sometimes further discounted based on management’s historical knowledge, changes in market conditions from the time of valuation, and/or management’s expertise and knowledge of the client and client’s business. Such discounts are typically significant and result in a Level 3 classification of the inputs for determining fair value. In cases where the carrying amount exceeds the fair value, less costs to sell, an impairment loss is recognized. Commitments to extend credit and letters of credit: Commitments to extend credit and fund letters of credit are principally at current interest rates, and, therefore, the carrying amount approximates fair value. The fair value of commitments is not material. (22.)

Disclosures about Fair Value of Financial Instruments The assumptions used below are expected to approximate those that market participants would use in valuing these financial instruments. Fair value estimates are made at a specific point in time, based on available market information and judgments about the financial instrument, including estimates of timing, amount of expected future cash flows and the credit standing of the issuer. Such estimates do not consider the tax impact of the realization of unrealized gains or losses. In some cases, the fair value estimates cannot be substantiated by comparison to independent markets. In addition, the disclosed fair value may not be realized in the immediate settlement of the financial instrument. Care should be exercised in deriving conclusions about our business, its value or financial position based on the fair value information of financial instruments presented below. The estimated fair value approximates carrying value for cash and cash equivalents, FHLB and FRB stock, accrued interest receivable, non-maturity deposits, short-term borrowings and accrued interest payable. Fair value estimates for other financial instruments not included elsewhere in this disclosure are discussed below. Securities held to maturity: The fair value of the Company’s investment securities held to maturity is primarily measured using information from a third-party pricing service. The fair value measurements 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. Loans: The fair value of the Company’s loans was estimated by discounting the expected future cash flows using the current interest rates at which similar loans would be made for the same remaining maturities. Loans were first segregated by type such as commercial, residential mortgage, and consumer, and were then further segmented into fixed and variable rate and loan quality categories. Expected future cash flows were projected based on contractual cash flows, adjusted for estimated prepayments. Time deposits: The fair value of time deposits was estimated using a discounted cash flow approach that applies prevailing market interest rates for similar maturity instruments. The fair values of the Company’s time deposit liabilities do not take into consideration the value of the Company’s long-term relationships with depositors, which may have significant value. Long-term borrowings: Long-term borrowings consist of $75 million of subordinated notes. The subordinated notes are publicly traded and are valued based on market prices, which are characterized as Level 2 liabilities in the fair value hierarchy. (22.)

Segment Reporting [Abstract]
Segment Reporting	(24.) Effective with year-end December 31, 2020, the Company reduced its reportable segments to one, as it determined that the previously disclosed “Non-Banking” reportable segment no longer met the quantitative or qualitative thresholds for separate disclosure. Previously reported results have been reclassified to conform to the current reporting structure. The Company has one reportable segment, Banking, which includes all of the Company’s retail and commercial banking operations. This reportable segment has been identified and organized based on the nature of the underlying products and services applicable to the segment, the type of customers to whom those products and services are offered and the distribution channel through which those products and services are made available. All other segments that do not meet the quantitative threshold for separate reporting have been grouped as “All Other.” This “All Other” grouping includes the activities of SDN, a full service insurance agency that provides a broad range of insurance services to both personal and business clients, Courier Capital and HNP Capital, our investment advisor and wealth management firms that provide customized investment management, investment consulting and retirement plan services to individuals, businesses, institutions, foundations and retirement plans, and Holding Company amounts, which are the primary differences between segment amounts and consolidated totals, along with amounts to eliminate balances and transactions between segments.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2020
Accounting Policies [Abstract]
Principles of Consolidation	(a.) Principles of Consolidation The consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	(b.) Use of Estimates In preparing the consolidated financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amount of assets and liabilities as of the date of the statement of financial condition and reported amounts of revenue and expenses during the reporting period. Material estimates relate to the determination of the allowance for credit losses, the carrying value of goodwill and deferred tax assets, and assumptions used in the defined benefit pension plan accounting. These estimates and assumptions are based on management’s best estimates and judgment and are evaluated on an ongoing basis using historical experience and other factors, including the current economic environment. The Company adjusts these estimates and assumptions when facts and circumstances dictate. As future events cannot be determined with precision, actual results could differ significantly from the Company’s estimates.
Cash Flow Reporting	(c.) Cash Flow Reporting Cash and cash equivalents include cash and due from banks, federal funds sold and interest-bearing deposits in other banks. Net cash flows are reported for loans, deposit transactions and short-term borrowings. Supplemental cash flow information is summarized as follows for the years ended December 31 (in thousands): 2020 2019 2018 Supplemental information: Cash paid for interest $ 28,875 $ 37,225 $ 28,626 Cash paid for income taxes, net of refunds received 7,462 9,853 3,527 Noncash investing and financing activities: Real estate and other assets acquired in settlement of loans $ 2,966 $ 557 $ 642 Accrued and declared unpaid dividends 4,535 4,365 4,187 (Decrease) increase in net unsettled security purchases - (2,650 ) 2,650 Securities transferred from held to maturity to available for sale (at cost) - 26,175 - Common stock issued for Courier Capital contingent earn-out - 1,151 - Assets acquired and liabilities assumed in business combinations: Fair value of assets acquired - - 2,561 Fair value of liabilities assumed - - 128
Investment Securities	(d.) Investment Securities Investment securities are classified as either available for sale (“AFS”) or held to maturity (“HTM”). Debt securities that management has the positive intent and ability to hold to maturity are classified as held to maturity and are recorded at amortized cost. Other investment securities are classified as available for sale and recorded at fair value, with unrealized gains and losses excluded from earnings and reported as a component of comprehensive income (loss) and shareholders’ equity. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method.
Loans Held For Sale And Loan Servicing Rights	(e.) Loans Held for Sale and Loan Servicing Rights The Company generally makes the determination of whether to identify a mortgage as held for sale at the time the loan is closed based on the Company’s intent and ability to hold the loan. Loans held for sale are recorded at the lower of cost or market computed on the aggregate portfolio basis. The amount by which cost exceeds market value, if any, is accounted for as a valuation allowance with changes included in the determination of results of operations for the period in which the change occurs. The amount of loan origination costs and fees are deferred at origination and recognized as part of the gain or loss on sale of the loans, determined using the specific identification method, in the consolidated statements of income. The Company originates and sells certain residential real estate loans in the secondary market. The Company typically retains the right to service the mortgages upon sale. Mortgage-servicing rights (“MSRs”) represent the cost of acquiring the contractual rights to service loans for others. MSRs are recorded at their fair value at the time a loan is sold and servicing rights are retained. MSRs are reported in other assets in the consolidated statements of financial position and are amortized to noninterest income in the consolidated statements of income in proportion to and over the period of estimated net servicing income. The Company uses a valuation model that calculates the present value of future cash flows to determine the fair value of servicing rights. In using this valuation method, the Company incorporates assumptions to estimate future net servicing income, which include estimates of the cost to service the loan, the discount rate, an inflation rate and prepayment speeds. On a quarterly basis, the Company evaluates its MSRs for impairment and charges any such impairment to current period earnings. In order to evaluate its MSRs the Company stratifies the related mortgage loans on the basis of their predominant risk characteristics, such as interest rates, year of origination and term, using discounted cash flows and market-based assumptions. Impairment of MSRs is recognized through a valuation allowance, determined by estimating the fair value of each stratum and comparing it to its carrying value. Subsequent increases in fair value are adjusted through the valuation allowance, but only to the extent of the valuation allowance. Mortgage loan servicing includes collecting monthly mortgagor payments, forwarding payments and related accounting reports to investors, collecting escrow deposits for the payment of mortgagor property taxes and insurance, paying taxes and insurance from escrow funds when due and administrating foreclosure actions when necessary. Loan servicing income (a component of noninterest income in the consolidated statements of income) consists of fees earned for servicing mortgage loans sold to third parties, net of amortization expense and impairment losses associated with capitalized mortgage servicing assets.
Loans	(f.) Loans Loans are classified as held for investment when management has both the intent and ability to hold the loan for the foreseeable future, or until maturity or payoff. Loans are carried at the principal amount outstanding, net of any unearned income and unamortized deferred fees and costs on originated loans. Loan origination fees and certain direct loan origination costs are deferred, and the net amount is amortized into net interest income over the contractual life of the related loans or over the commitment period as an adjustment of yield. Interest income on loans is based on the principal balance outstanding computed using the effective interest method. A loan is considered delinquent when a payment has not been received in accordance with the contractual terms. The accrual of interest income for commercial loans is discontinued when there is a clear indication that the borrower’s cash flow may not be sufficient to meet payments as they become due, while the accrual of interest income for retail loans is discontinued when loans reach specific delinquency levels. Loans are generally placed on nonaccrual status when contractually past due 90 days or more as to interest or principal payments, unless the loan is well secured and in the process of collection. Additionally, if management becomes aware of facts or circumstances that may adversely impact the collectability of principal or interest on loans, it is management’s practice to place such loans on a nonaccrual status immediately, rather than delaying such action until the loans become 90 days past due. When a loan is placed on nonaccrual status, previously accrued and uncollected interest is reversed, amortization of related deferred loan fees or costs is suspended, and income is recorded only to the extent that interest payments are subsequently received in cash and a determination has been made that the principal balance of the loan is collectible. If collectability of the principal is in doubt, payments received are applied to loan principal. A nonaccrual loan may be returned to accrual status when all delinquent principal and interest payments become current in accordance with the terms of the loan agreement, the borrower has demonstrated a period of sustained performance (generally a minimum of six months) and the ultimate collectability of the total contractual principal and interest is no longer in doubt. The Company’s loan policy dictates the guidelines to be followed in determining when a loan is charged-off. All charge offs are approved by the Bank’s senior loan officers or loan committees, depending on the amount of the charge off, and are reported in aggregate to the Bank’s Board of Directors. Commercial business and commercial mortgage loans are charged-off when a determination is made that the financial condition of the borrower indicates that the loan will not be collectible in the ordinary course of business. Residential mortgage loans and home equities are generally charged-off or written down when the credit becomes severely delinquent and the balance exceeds the fair value of the property less costs to sell. Indirect and other consumer loans, both secured and unsecured, are generally charged-off in full during the month in which the loan becomes 120 days past due, unless the collateral is in the process of repossession in accordance with the Company’s policy. A loan is accounted for as a troubled debt restructuring if the Company, for economic or legal reasons related to the borrower’s financial condition, grants a significant concession to the borrower that it would not otherwise consider. A troubled debt restructuring may involve the receipt of assets from the debtor in partial or full satisfaction of the loan, or a modification of terms such as a reduction of the stated interest rate or face amount of the loan, a reduction of accrued interest, an extension of the maturity date at a stated interest rate lower than the current market rate for a new loan with similar risk, or some combination of these concessions. Troubled debt restructurings generally remain on nonaccrual status until there is a sustained period of payment performance (usually six months or longer) and there is a reasonable assurance that the payments will continue. See Allowance for Credit Losses below for further policy discussion and see Note 6 – Loans for additional information.
Off-Balance Sheet Financial Instruments	(g.) Off-Balance Sheet Financial Instruments In the ordinary course of business, the Company enters into off-balance sheet financial instruments consisting of commitments to extend credit, standby letters of credit and financial guarantees. Such financial instruments are recorded in the consolidated financial statements when they are funded or when related fees are incurred or received. The Company periodically evaluates the credit risks inherent in these commitments and establishes loss allowances for such risks if and when these are deemed necessary. The Company recognizes as liabilities the fair value of the obligations undertaken in issuing the guarantees under the standby letters of credit, net of the related amortization at inception. The fair value approximates the unamortized fees received from the customers for issuing the standby letters of credit. The fees are deferred and recognized on a straight-line basis over the commitment period. Standby letters of credit outstanding typically have original terms ranging from one to five years. Fees received for providing loan commitments and letters of credit that result in loans are typically deferred and amortized to interest income over the life of the related loan, beginning with the initial borrowing. Fees on commitments and letters of credit are amortized to other income as banking fees and commissions over the commitment period when funding is not expected.
Allowance for Credit Losses	(h.) Allowance for Credit Losses The allowance for credit losses is established through charges to earnings in the form of a provision for credit losses. When a loan or portion of a loan is determined to be uncollectible, the portion deemed uncollectible is charged against the allowance and subsequent recoveries, if any, are credited to the allowance. Portfolio Segmentation and “Pooled Loans” Calculation Loans are pooled based on their homogeneous risk characteristics. Once loans have been segmented into pools, a loss rate is applied to the amortized cost basis. The Company has divided its portfolio into six segments, as the loans within the segments have similar characteristics. Characteristics considered include: purpose, tenor, amortization, repayment source, payment frequency, collateral and recourse. The Company has identified six portfolio segments of loans including Commercial Loans/Lines, Commercial Mortgage, Indirect Loans, Direct Loans, Residential Lines of Credit, and Residential Loans. The Company utilizes the Discounted Cash Flow (“DCF”) method for its pooled segment calculation. The DCF method implements a Probability of Default with Loss Given Default and Exposure at Default estimation. The Probability of Default and Loss Given Default are applied to future cash flows that are adjusted to present value and these discounted expected losses become the Allowance for Credit Losses. DCF analysis is reliant upon a variety of loan-level data, peripheral model outputs and key assumptions. The data fields required to create the contractual portion of the forward-looking cash flow schedule relate to the terms of each loan and include information regarding payment amount, payment frequency, interest rate, interest type, maturity date, amortization term, etc. Contractual terms must be adjusted for prepayments to arrive at expected cashflows. The Company modeled amortizing/installment notes with a prepayment rate, annualized to one-year. For loans where principal collection is dominated by borrower election, e.g. lines of credit, interest-only, etc., and not by contractual obligation, the Company modeled a statistical tendency to repay as a curtailment rate, normalized to a one-year rate. The Company uses forecasts to predict how modeled economic factors will perform. The Company currently elects to forecast economic factors over a period for which it can produce a reliable and defensible forecast from widely accepted economic forecast resources. After the forecast period, the following eight quarters are reverted on a straight-line basis to the economic factor’s average. The Company uses an eight-quarter straight-line reversion to reduce the potential for a spike impact on the model caused by a rapid reversion. Additionally, as the Company is past its point of forecast, a straight-line reversion represents a most-likely scenario absent a hard forecast. In the Company’s analysis at the portfolio level, it found that the best model for predicting defaults considers the National Unemployment Rate. With the large number of observations afforded by using peer data, the default curve is less sensitive to unusual loss events and has a much smoother shape. The national unemployment rate is an extremely strong predictor of defaults and explains almost all variation in the default rate. CECL requires calculating a reserve based on a life of loan basis. The life of loan is assumed with consideration of prepayments and contractual maturity dates. If a given loan does not have a populated maturity date, based upon historical experience, the Company elected to amortize the loan for a length of time equal to the average life of the loan’s segment before the remaining balance will balloon with the exception of Commercial Demand Lines of Credit where the Company uses one year, reflecting the demand nature of these exposures with annual review. Management also considers Qualitative Factors (“QF”) that are likely to cause estimated credit losses with the Company’s existing portfolio to differ from historical loss experience, including but not limited to: national and local economic trends and conditions (excluding national unemployment), levels and trends in delinquencies, non-accrual loans and classified assets, trends in volume, terms and concentrations of loans, changes in lending policies and procedures, Quality of Credit Review function and administration, and changes in regulatory environment. The Company will periodically assess what adjustments are necessary to qualitatively adjust the ACL based on their assessment of current expected credit losses. The range for the QF in a specific pool represents the difference, in basis points between the portfolio segment loss explained by the regression analysis (r-squared factor) and the total loss for that period, looking back to 2006, when the Company experienced its highest four quarter loss rate. In this approach, the Company is capturing, based upon historical experience, its largest potential loss rate. Where possible, the QF are calculated using available data sources to support the allocation of basis points within the ranges. For example, delinquency for a segment is mapped backed to 2006 and current delinquency is allocated a QF based upon where it lies in that range. (1.) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) Individually Analyzed Loans Excluded from pooled analysis are loans to be individually analyzed due to the assets not maintaining similar risk characteristics to those in the six designated segments. These loans are generally considered to be collateral dependent and, therefore, an analysis of the collateral position versus the pooled loan discounted cash flow approach better reflects the potential loss. Individually analyzed accounts include: loans over 90 days past due, loans marked as Trouble Debt Restructure (“TDR”), loans placed on non-accruals status and criticized assets with exposure greater than $2.0 million. In addition, certain commercial loans are on long term deferral due to the impacts of the COVID-19 pandemic. While not criticized assets, these loans reflect unique characteristics and warrant individual analysis. Management reviewed these loans and elected to remove certain loans from the pooled loan analysis based upon characteristics including industry, which evidence a higher risk of loss from the impact of the pandemic. These loans were individually analyzed, and reserves allocated to them based upon collateral position. Management continues to assess the status of these loans for risk characteristics. Held to Maturity (“HTM”) Debt Securities The Company’s HTM debt securities are also required to utilize the current expected credit losses approach to estimate expected credit losses. The Company’s HTM debt securities included securities that are issued by U.S. government agencies or U.S. government-sponsored enterprises. These securities carry the explicit and/or implicit guarantee of the U.S. government, are widely recognized as “risk free,” and have a long history of zero credit loss. The Company also carries a portfolio of HTM municipal bonds. The Company measures its allowance for credit losses on HTM debt securities on a collective basis by major security type. The estimate is based on historical credit losses, if any, adjusted for current conditions and reasonable and supportable forecasts. The Company considers the nature of the collateral, potential future changes in collateral values and available loss information. Available for Sale (“AFS”) Debt Securities For AFS securities in an unrealized loss position, we first assess whether (i) we intend to sell, or (ii) it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. If either case is affirmative, any previously recognized allowances are charged-off and the security's amortized cost is written down to fair value through income. If neither case is affirmative, the security is evaluated to determine whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and any adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. Adjustments to the allowance are reported in our income statement as a component of provision for credit losses. AFS securities are charged-off against the allowance or, in the absence of any allowance, written down through income when deemed uncollectible by management or when either of the aforementioned criteria regarding intent or requirement to sell is met. (1.) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) Accrued Interest Receivable Upon adoption of ASU 2016-13 and its related amendments on January 1, 2020, the Company made the following elections regarding accrued interest receivable: • Presenting accrued interest receivable balances separately within other assets on the statement of financial condition. • Excluding accrued interest receivable that is included in the amortized cost of financing receivables and debt securities from related disclosure requirements. • Continuing our policy to write off accrued interest receivable by reversing interest income. For commercial loans, the write off typically occurs upon becoming 90 days past due. For consumer loans, the write off typically occurs upon becoming 120 days past due. Historically, the Company has not experienced uncollectible accrued interest receivable on its investment securities. However, the Company would generally write off accrued interest receivable by reversing interest income if the Company does not reasonably expect to receive payments. Due to the timely manner in which accrued interest receivables are written off, the amounts of such write offs are immaterial. • The Company had made the election with the adoption of ASU 2016-13 of not measuring an allowance for credit losses for accrued interest receivable due to the Company’s policy of writing off uncollectible accrued interest receivable balances in a timely manner, as described above. Reserve for Unfunded Commitments The reserve for unfunded commitments (the “Unfunded Reserve”) represents the expected credit losses on off-balance sheet commitments such as unfunded commitments to extend credit and standby letters of credit. However, a liability is not recognized for commitments unconditionally cancellable by the Company. The Unfunded Reserve is recognized as a liability (other liabilities in the consolidated statements of financial condition), with adjustments to the reserve recognized as a provision for credit loss expense in the consolidated statements of income. The Unfunded Reserve is determined by estimating expected future fundings, under each segment, and applying the expected loss rates. Expected future fundings are based on historical averages of funding rates (i.e., the likelihood of draws taken). Average funding rates are determined based on the most recent 20 quarters (5 years) of actual fundings on lines of credit. The average funding rate for each segment is compared to the current funding rate on each line to determine the average fundings available to be drawn. The fund up rate (the difference between the average funding rate and the current funding rate) for each segment is then applied within the CECL model to the unfunded commitment balance to estimate the expected future fundings under each segment. The loss rate derived for each segment in the current CECL calculation is then applied to the expected future fundings to derive the estimate of allowance for credit losses for unfunded commitments.
Other Real Estate Owned	(i.) Other Real Estate Owned Other real estate owned consists of properties acquired through foreclosure or by acceptance of a deed in lieu of foreclosure. These assets are initially recorded at fair value less estimated costs to sell, which establishes the cost basis. Subsequently, other real estate owned is carried at the lower of the cost basis or fair value less estimated selling costs. At the time of foreclosure, or when foreclosure occurs in-substance, the excess, if any, of the loan over the fair market value of the assets received, less estimated selling costs, is charged to the allowance for credit losses and any subsequent valuation write-downs are charged to other expense. In connection with the determination of the allowance for credit losses and the valuation of other real estate owned, management obtains appraisals for properties. Operating costs associated with the properties are charged to expense as incurred. Gains on the sale of other real estate owned are included in income when title has passed and the sale has met the minimum down payment requirements prescribed by GAAP. The balance of other real estate owned was $3.0 million and $468 thousand at December 31, 2020 and 2019, respectively.
Company Owned Life Insurance	(j.) Company Owned Life Insurance The Company holds life insurance policies on certain current and former employees. The Company is the owner and beneficiary of the policies. The cash surrender value of these policies is included as an asset on the consolidated statements of financial condition, and any increase in cash surrender value is recorded as noninterest income on the consolidated statements of income. In the event of the death of an insured individual under these policies, the Company would receive a death benefit which would be recorded as noninterest income.
Premises and Equipment	(k.) Premises and Equipment Premises and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation is computed on the straight-line method over the estimated useful lives of the assets. The Company generally amortizes buildings and building improvements over a period of 15 to 39 years and software, furniture and equipment over a period of 3 to 10 years. Leasehold improvements are amortized over the shorter of the lease term or the useful life of the improvements. Premises and equipment are periodically reviewed for impairment or when circumstances present indicators of impairment.
Goodwill and Other Intangible Assets	(l.) Goodwill and Other Intangible Assets The excess of the cost of an acquisition over the fair value of the net assets acquired consists primarily of goodwill, core deposit intangibles, and other identifiable intangible assets. Intangible assets are acquired assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset, or liability. The Company’s intangible assets consist of core deposits and other intangible assets (primarily customer relationships). Core deposit intangible assets are amortized on an accelerated basis over their estimated life of approximately nine and a half years Goodwill is not amortized but, instead, is subject to impairment tests on at least an annual basis, and more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The impairment testing process is conducted by assigning net assets and goodwill to each reporting unit. An initial qualitative evaluation is made to assess the likelihood of impairment and determine whether further quantitative testing to calculate the fair value is necessary. When the qualitative evaluation indicates that impairment is more likely than not, quantitative testing is required whereby the fair value of each reporting unit is calculated and compared to the recorded book value. If the calculated fair value of the reporting unit exceeds its carrying value, then goodwill is not considered impaired. However, if the carrying value of a reporting unit exceeds its calculated fair value, a goodwill impairment charge is recognized. See Note 8 for additional information on goodwill and other intangible assets.
Federal Home Loan Bank (“FHLB”) and Federal Reserve Bank (“FRB”) Stock	(m.) Federal Home Loan Bank (“FHLB”) and Federal Reserve Bank (“FRB”) Stock The non-marketable investments in FHLB and FRB stock are included in other assets in the consolidated statements of financial condition at par value or cost and are periodically reviewed for impairment. The dividends received relative to these investments are included in other noninterest income in the consolidated statements of income. As a member of the FHLB system, the Company is required to maintain a specified investment in FHLB of New York (“FHLBNY”) stock in proportion to its volume of certain transactions with the FHLB. FHLBNY stock totaled $2.6 million and $14.6 million as of December 31, 2020 and 2019, respectively. As a member of the FRB system, the Company is required to maintain a specified investment in FRB stock based on a ratio relative to the Company’s capital. FRB stock totaled $6.1 million as of December 31, 2020 and 2019.
Equity Method Investments	(1.) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) (n.) Equity Method Investments The Company has investments in limited partnerships, primarily Small Business Investment Companies, and accounts for these investments under the equity method. These investments are included in other assets in the consolidated statements of financial condition and totaled $7.9 million and $7.6 million as of December 31, 2020 and 2019, respectively.
Derivative Instruments and Hedging Activities	(o.) Derivative Instruments and Hedging Activities Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 815, Derivatives and Hedging (“ASC 815”), provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (a) how and why an entity uses derivative instruments, (b) how the entity accounts for derivative instruments and related hedged items, and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. Further, qualitative disclosures are required that explain the Company’s objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative instruments. As required by ASC 815, the Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative. Changes in fair value of the Company’s derivatives designated in a qualifying hedging relationship are recorded in accumulated other comprehensive income (loss). Changes in fair value of the Company’s derivatives not designated in a qualifying hedging relationship are recognized directly in earnings. In accordance with the FASB’s fair value measurement guidance, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio.
Treasury Stock	(p.) Treasury Stock Acquisitions of treasury stock are recorded at cost. The reissuance of shares in treasury is recorded at weighted-average cost.
Transfers of Financial Assets	(q.) Transfers of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered. Control over financial assets is deemed surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of the right) to pledge or exchange the transferred assets and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Revenue Recognition	(1.) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) (r.) Revenue Recognition ASC 606, Revenue from Contracts with Customers (“ASC 606”), establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from the entity’s contracts to provide goods or services to customers. The core principle requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those goods or services recognized as performance obligations are satisfied. The majority of our revenue-generating transactions are not subject to ASC 606, including revenue generated from financial instruments, such as our loans, letters of credit, derivatives and investment securities, as well as revenue related to our loan servicing activities, as these activities are subject to other GAAP. Descriptions of our primary revenue-generating activities that are within the scope of ASC 606, which are presented in our income statements as components of noninterest income are as follows: • Transactions and service-based revenues - these include service charges on deposits, investment advisory, and ATM and debit card fees. Revenue is recognized when the transactions occur or as services are performed over primarily monthly or quarterly periods. Payment is typically received in the period the transactions occur or, in some cases, within 90 days of the service period. Fees may be fixed or, where applicable, based on a percentage of transaction size or managed assets. • Insurance income - Insurance commissions are received on the sale of insurance products, and revenue is recognized upon the placement date of the insurance policies. Payment is normally received within the policy period. In addition to placement, SDN also provides insurance policy related risk management services. Revenue is recognized as these services are provided.
Employee Benefits	(s.) Employee Benefits The Company maintains an employer sponsored 401(k) plan where participants may make contributions in the form of salary deferrals and the Company may provide discretionary matching contributions in accordance with the terms of the plan. Contributions due under the terms of our defined contribution plans are accrued as earned by employees. The Company also participates in a non-contributory defined benefit pension plan for certain employees who previously met participation requirements. The Company also provides post-retirement benefits, principally health and dental care, to employees of a previously acquired entity. The Company has closed the pension and post-retirement plans to new participants. The actuarially determined pension benefit is based on years of service and the employee’s highest average compensation during five consecutive years of employment. The Company’s policy is to at least fund the minimum amount required by the Employment Retirement Income Security Act of 1974. The cost of the pension and post-retirement plans are based on actuarial computations of current and future benefits for employees and is charged to noninterest expense in the consolidated statements of income. The Company recognizes an asset or a liability for a plan’s overfunded status or underfunded status, respectively, in the consolidated financial statements and reports changes in the funded status as a component of other comprehensive income, net of applicable taxes, in the year in which changes occur. Effective January 1, 2016, the Company’s 401(k) plan was amended, and the Company’s prior matching contribution was discontinued. Concurrent with the 401(k) plan amendment, the Company’s defined benefit pension plan was amended to modify the current benefit formula to reflect the discontinuance of the matching contribution in the 401(k) plan, to open the defined benefit pension plan up to eligible employees who were hired on and after January 1, 2007, which provides those new participants with a cash balance benefit formula.
Share-Based Compensation Plans	(t.) Share-Based Compensation Plans Compensation expense for stock options, restricted stock awards and restricted stock units is based on the fair value of the award on the measurement date, which, for the Company, is the date of grant and is recognized ratably over the service period of the award. The fair value of stock options is estimated using the Black-Scholes option-pricing model. The fair value of restricted stock awards and restricted stock units is generally the market price of the Company’s stock on the date of grant. Share-based compensation expense is included in the consolidated statements of income under salaries and employee benefits for awards granted to management and in other noninterest expense for awards granted to directors.
Income Taxes	(1.) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) (u.) Income Taxes Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. A valuation allowance is recognized on deferred tax assets if, based upon the weight of available evidence, it is more likely than not that some or all of the assets may not be realized. The Company recognizes interest and/or penalties related to income tax matters in income tax expense. The Company has investments in partnerships that incur qualified expenses related to the rehabilitation of certified structures. At the time that a structure is placed into service, the Company is eligible for federal and New York State tax credits. The federal tax credit impact is recorded as a reduction of income tax expense. For a New York State tax credit generated after January 1, 2015, the amount not used in the current tax year is treated as a refund or overpayment of tax to be credited to next year’s tax. Since the realization of the tax credit does not depend on the Company’s generation of future taxable income or the Company’s ongoing tax status or tax position, the credit is not considered an element of income tax accounting (ASC 740). The Company includes the tax credit in non-interest income as opposed to a reduction of income tax expense. At the time that a structure is placed into service, the Company records a loss on tax credit investments in noninterest income to reduce the investment to the present value of the expected cash flows from its partnership interest. The Company has investments in qualified affordable housing projects that are accounted for using the proportional amortization method. Under that method, the Company amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net amount as a reduction of income tax expense. These tax credit investments are included in other assets in the consolidated statements of financial condition and totaled $34.4 million and $16.5 million as of December 31, 2020 and 2019, respectively.
Comprehensive Income (Loss)	(v.) Comprehensive Income (Loss) Comprehensive income (loss) includes all changes in shareholders’ equity during a period, except those resulting from transactions with shareholders. In addition to net income, other components of the Company’s comprehensive income (loss) include the after-tax effect of changes in net unrealized gain / loss on securities available for sale, changes in unrealized gain / loss on hedging derivative instruments and changes in net actuarial gain / loss on defined benefit post-retirement plans. Comprehensive income (loss) is reported in the accompanying consolidated statements of changes in shareholders’ equity and consolidated statements of comprehensive income (loss). See Note 17 - Accumulated Other Comprehensive Income (Loss) for additional information.
Earnings Per Common Share	(w.) Earnings Per Common Share The Company calculates earnings per common share (“EPS”) using the two-class method in accordance with FASB ASC Topic 260, “Earnings Per Share”. The two-class method requires the Company to present EPS as if all of the earnings for the period are distributed to common shareholders and any participating securities, regardless of whether any actual dividends or distributions are made. All outstanding unvested share-based payment awards that contain rights to non-forfeitable dividends are considered participating securities. Basic EPS is computed by dividing distributed and undistributed earnings available to common shareholders by the weighted average number of common shares outstanding for the period. Distributed and undistributed earnings available to common shareholders represent net income reduced by preferred stock dividends and distributed and undistributed earnings available to participating securities. Common shares outstanding include common stock and vested restricted stock awards. Diluted EPS reflects the assumed conversion of all potential dilutive securities. A reconciliation of the weighted-average shares used in calculating basic earnings per common share and the weighted average common shares used in calculating diluted earnings per common share for the reported periods is provided in Note 20 - Earnings Per Common Share.
Reclassifications	(1.) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) (x.) Reclassifications Certain items in prior financial statements have been reclassified to conform to the current presentation. These reclassifications did not result in any changes to previously reported net income or shareholders’ equity.
Recent Accounting Pronouncements	(y.) Recent Accounting Pronouncements On January 1, 2020, the Company adopted Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments In August 2018, the FASB issued ASU No. 2018-14, Compensation – Retirement Benefits – Defined Benefit Plans – General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans In April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments Derivatives and Hedging (Topic 815) – Targeted Improvements to Accounting for Hedging Activities $26.2 (1.) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) In 2017, the United Kingdom’s Financial Conduct Authority, who is responsible for regulating LIBOR, announced its intention that it would no longer be necessary to persuade or compel its panel banks to submit LIBOR rates after December 31, 2021. Given that LIBOR is a widely used pricing index for loan and derivative contracts, a Company-wide initiative was introduced to assess all LIBOR exposures through the Company’s loan, deposit, borrowing and derivative categories, while developing a plan for the ultimate cessation of the index. In developing the transition plan, the Company has followed best practice recommendations from the Federal Reserve’s Alternative Reference Rate Committee, our third-party derivative advisor and the Internal Swaps and Derivatives Association. To date, the Company has identified the portion of loan notes that reference LIBOR, which are primarily representative of commercial relationships. Additionally, the Company has one designated derivative instrument that is utilized to hedge the LIBOR characteristic of a future dated borrowing (i.e. Federal Home Loan Bank Advance). In 2015, the Company issued a $40 million fixed to floating rate subordinated debt instrument that currently bears a fixed rate of interest at 6.00% until April 2025, when the rate converts to a floating rate structured indexed to three-month LIBOR; the indenture under which the notes were issued includes language allowing an alternate index to be applied in the event that LIBOR becomes unavailable at the floating rate determination date. At this time, no other borrowing or deposit relationships have been identified that utilize LIBOR as an index. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting In January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848): Scope
