Summary Of Significant Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	NOTE A – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The consolidated financial statements include the accounts of The First of Long Island Corporation and its wholly-owned subsidiary, The First National Bank of Long Island, and subsidiaries wholly-owned by the Bank, either directly or indirectly: The First of Long Island Agency, Inc.; FNY Service Corp.; and The First of Long Island REIT, Inc. (“REIT”). The Corporation’s financial condition and operating results principally reflect those of the Bank and its subsidiaries. The consolidated entity is referred to as the “Corporation,” and the Bank and its subsidiaries are collectively referred to as the “Bank.” All intercompany balances and amounts have been eliminated. The accounting and reporting policies of the Corporation reflect banking industry practice and conform to generally accepted accounting principles (“GAAP”) in the United States. The following is a summary of the Corporation’s significant accounting policies. In preparing the consolidated financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported asset and liability balances, revenue and expense amounts, and the disclosures provided, including disclosure of contingent assets and liabilities, based on available information. Actual results could differ significantly from those estimates. Information available which could affect these judgements include, but are not limited to, changes in interest rates, changes in the performance of the economy including the economic impact of the COVID-19 pandemic (“pandemic”) on both the allowance and provision for credit losses, and changes in the financial condition of borrowers. Adoption of New Accounting Standards In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13 “Measurement of Credit Losses on Financial Instruments (Topic 326)” (“CECL”) . This standard changes the methodology used to determine the allowance for loan losses from an incurred loss model to a current expected credit loss model. The CECL model requires the Bank to maintain at each periodic reporting date an allowance for credit losses (“ACL” or “allowance”) in an amount that is equal to its estimate of expected lifetime credit losses on all financial assets measured at amortized cost, including loan receivables, held-to-maturity debt securities and certain off-balance sheet credit exposures. Management adopted ASU 2016-13, as amended, on January 1, 2020 using the modified retrospective approach for all financial assets measured at amortized cost and off-balance sheet credit commitments. Results for reporting periods beginning on or after January 1, 2020 are presented under Accounting Standards Codification (“ASC”) 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. On January 1, 2020, the Corporation recorded a net decrease to retained earnings of $ 2,325,000 , net of tax effect of $ 993,000 , for the implementation of ASC 326, with offsetting increases of $ 2,888,000 and $ 430,000 to the ACL on loans and off-balance sheet credit exposures, respectively. The following table illustrates the impact of ASC 326. January 1, 2020 Impact of As Reported Pre-ASC 326 ASC 326 (in thousands) Under ASC 326 Adoption Adoption Assets: Allowance for credit losses on loans: Commercial and industrial $ 1,249 $ 1,493 $ ( 244 ) Commercial mortgages: Multifamily 8,210 7,151 1,059 Other 3,451 3,498 ( 47 ) Owner-occupied 1,699 921 778 Residential mortgages: Closed end 17,054 15,698 1,356 Revolving home equity 509 515 ( 6 ) Consumer and other 5 13 ( 8 ) $ 32,177 $ 29,289 $ 2,888 Liabilities: Allowance for credit losses on off-balance sheet credit exposures $ 605 $ 175 $ 430 In August 2018, the FASB issued ASU 2018-13 “Changes to the Disclosure Requirements for Fair Value Measurement” to modify certain disclosures pertaining to fair value measurements as part of the FASB’s disclosure framework project. Management adopted ASU 2018-13 on January 1, 2020. See Note M “Fair Value of Financial Instruments” for disclosures required by ASU 2018-13. Cash and Cash Equivalents Cash and cash equivalents include cash and deposits with other financial institutions that generally mature within 90 days. Investment Securities Current accounting standards require that investment securities be classified as held-to-maturity, available-for-sale or trading. The trading category is not applicable to any securities in the Bank's portfolio because the Bank does not buy or hold debt or equity securities principally for the purpose of selling in the near term. Held-to-maturity securities, or debt securities which the Bank has the intent and ability to hold to maturity, are reported at amortized cost. Available-for-sale securities, or debt securities which are neither held-to-maturity securities nor trading securities, are reported at fair value, with unrealized gains and losses, net of the related income tax effect, included in other comprehensive income (loss) (“OCI”). Equity securities, if any, are carried at fair value, with changes in fair value reported in net income. Equity securities without readily determinable fair values are carried at cost, minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment. Interest income includes amortization or accretion of purchase premium or discount. Premiums and discounts on securities are amortized or accreted using the level-yield method. Prepayments are anticipated for mortgage-backed securities. Premiums on municipal securities are amortized to the earlier of the stated maturity date or the first call date, while discounts on municipal securities are accreted to the stated maturity date. Realized gains and losses on the sale of securities are determined using the specific identification method. Management measures expected credit losses on held-to-maturity debt securities, if any, on a collective basis by major security type. Accrued interest receivable on held-to maturity debt securities is excluded from the estimate of credit losses. For available-for-sale securities in an unrealized loss position, management first evaluates whether the decline in fair value has resulted from an actual or estimated credit loss event. Management considers, among other factors, the extent to which fair value is less than amortized cost, changes to the rating of the security, and adverse conditions specifically related to the security. If this assessment indicates that a credit loss is likely, management then assesses whether it has the intent to sell the security or more likely than not will be required to sell the security before recovery of its amortized cost and determines the present value of cash flows expected to be collected from the security as compared to the amortized cost basis of the security. If the present value of the cash flows expected to be collected is less than the amortized cost basis, an allowance is recorded for the estimated 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 is recognized in OCI. Accrued interest receivable on available-for-sale securities is excluded from the estimate of credit losses. Loans Held-for-Sale Loans held-for-sale are carried at the lower of cost or fair value. Any subsequent declines in fair value below the initial carrying value are recorded as a valuation allowance established through a charge to noninterest income. Loans and Allowance for Credit Losses Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost, net of the ACL. Amortized cost is the principal balance outstanding plus or minus net deferred loan costs and fees. Accrued interest receivable is reported in “Other assets” on the consolidated balance sheets and is excluded from the estimate of credit losses. Interest on loans is credited to income based on the principal amount outstanding. Direct loan origination costs, net of loan origination fees, are deferred and recognized in interest income using the level-yield method without anticipating prepayments. The past due status of a loan is based on the contractual terms in the loan agreement. Unless a loan is well secured and in the process of collection, the accrual of interest income is discontinued when a loan becomes 90 days past due as to principal or interest payments. The accrual of interest income on a loan is also discontinued when it is determined that the borrower will not be able to make principal and interest payments according to the contractual terms of the current loan agreement. When the accrual of interest income is discontinued on a loan, any accrued but unpaid interest is reversed against current period income. Interest received on nonaccrual loans is applied to the outstanding principal balance until the loans qualify for return to an accrual status, if ever. Return to an accrual status occurs when all the principal and interest amounts contractually past due are brought current and all future payments are reasonably assured. The ACL is a valuation account that is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on the Bank’s loan portfolio. The allowance is established through provisions for credit losses charged against income. When available information confirms that specific loans, or portions thereof, are uncollectible, these amounts are charged against the ACL, and subsequent recoveries, if any, are credited to the allowance. Management identifies loans in the Bank’s portfolio that must be individually evaluated for loss due to disparate risk characteristics or information suggesting that the Bank will be unable to collect all the principal and interest due. For loans individually evaluated, a specific reserve is estimated based on either the fair value of collateral or the discounted value of expected future cash flows. In estimating the fair value of real estate collateral, management utilizes appraisals or evaluations adjusted for costs to dispose and a distressed sale adjustment, if needed. Estimating the fair value of collateral other than real estate is also subjective in nature and sometimes requires difficult and complex judgements. Determining expected future cash flows can be more subjective than determining fair values. Expected future cash flows could differ significantly, both in timing and amount, from the cash flows actually received over the loan’s remaining life. Individually evaluated loans are excluded from the estimation of credit losses for the pooled portfolio. Troubled debt restructurings (“TDRs”) are individually evaluated for loss and generally reported at the present value of estimated future cash flows using the loan’s effective rate at inception. However, if a TDR is considered to be a collateral dependent loan, the loan is reported at the fair value of the collateral. For loans collectively evaluated for credit loss, management segregates its loan portfolio into eleven distinct pools, certain of which are combined in reporting loans outstanding by class of loans: (1) commercial and industrial; (2) small business credit scored; (3) multifamily; (4) owner-occupied; (5) other commercial real estate; (6) construction and land development; (7) closed end residential mortgage; (8) revolving home equity; (9) consumer; (10) municipal loans; and (11) Small Business Administration (“SBA”) Paycheck Protection Program (“PPP”) loans. Historical loss information from the Bank’s own loan portfolio from December 31, 2007 to present provides a basis for management’s assessment of expected credit losses. The choice of a historical look-back period that begins in 2007 covers an entire economic cycle and impacts the average historical loss rates used to calculate the final ACL. Due to the extensive historical loss data available, management has determined that the vintage approach is the most appropriate method of measuring the historical loss component of credit losses inherent in its portfolio for most of its loan pools. For the revolving home equity and small business credit scored pools, the migration approach was selected to measure historical losses since contractual lives are not readily discernable and balances can fluctuate throughout the life of the lines. Finally, no historical loss method was applied to the SBA PPP loan pool which is a new pool with no loss experience and is 100% guaranteed by the federal government. Management believes that the methods selected fairly reflect the historical loss component of expected losses inherent in the Bank’s loan portfolio. However, since future losses could vary significantly from those experienced in the past, on a quarterly basis management adjusts its historical loss experience to reflect current and forecasted conditions. In doing so, management considers a variety of general qualitative and quantitative factors (“Q-factors”) and then subjectively determines the weight to assign to each in estimating losses. Qualitative characteristics include, among others, differences in underwriting standards, policies, lending staff and environmental risks. Management also considers whether further adjustments to historical loss information are needed to reflect the extent to which current conditions and reasonable and supportable forecasts over a one year to two year forecasting horizon differ from the conditions that existed during the historical loss period. These quantitative adjustments reflect changes to relevant data such as changes in unemployment rates, GDP, vacancies, home prices, average growth in pools of loans, delinquencies or other factors associated with the financial assets. The allowance for SBA PPP loans represents an estimate of potential loss due to documentation and processing deficiencies. The immediate reversion method is applied for periods beyond the forecasting horizon. The Bank’s ACL allocable to pools of loans that are collectively evaluated for credit loss results primarily from these qualitative and quantitative adjustments to historical loss experience. Because of the nature of the Q-factors and the degree of judgement involved in assessing their impact, management’s resulting estimate of losses may not accurately reflect current and future losses in the portfolio. The ACL is an amount that management currently believes will be adequate to absorb current expected credit losses in the Bank’s loan portfolio. The process for estimating credit losses and determining the ACL as of any balance sheet date is subjective in nature and requires material estimates. Actual results could differ significantly from those estimates. Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Corporation, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Corporation does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Bank Premises and Equipment and Operating Leases Land is carried at cost. Other bank premises and equipment are carried at cost less accumulated depreciation and amortization. Buildings are depreciated using the straight-line method over their estimated useful lives, which range from 31 to 40 years. Building and leasehold improvements are depreciated using the straight-line method over the remaining lives of the buildings or leases, as applicable, or their estimated useful lives, whichever is shorter. The lives of the respective leases range from five years to twenty years . Furniture, fixtures and equipment are depreciated using the straight-line method over their estimated useful lives, which range from three years to ten years . Premises and equipment held-for-sale, if any, is included in “Other assets” on the Corporation’s consolidated balance sheet and carried at the lower of cost or fair value. The Bank determines if an arrangement is a lease at inception and recognizes a right-of-use (“ROU”) asset and lease liability at the commencement date based on the present value of lease payments over the lease term. As most of the Bank’s leases do not provide an implicit interest rate, the Bank uses its incremental borrowing rate to determine the present value of the lease payments. The Bank’s ROU asset and lease liability may include options to extend the lease when it is reasonably certain that the Bank will exercise that option. Lease expense is recognized on a straight-line basis over the lease term. Bank-owned Life Insurance The Bank is the owner and beneficiary of insurance policies on the lives of certain officers. Bank-owned life insurance (“BOLI”) is recorded at the amount that can be realized under the contract at the balance sheet date, which is the cash surrender value adjusted for other charges or amounts due that are probable at settlement, if any. Restricted Stock The Bank is a member of and is required to own stock in the Federal Home Loan Bank of New York (“FHLBNY”) and the Federal Reserve Bank of New York (“FRBNY”). The amount of FHLBNY stock held is based on membership and the level of FHLBNY advances. The amount of FRBNY stock held is based on the Bank’s capital and surplus balances. These stocks do not have a readily determinable fair value, are carried at cost, classified as restricted stock and periodically evaluated for impairment based on the prospects for the ultimate recovery of cost. Cash dividends, if any, are reported as interest income on taxable investment securities. Other Real Estate Owned Real estate acquired through foreclosure or by deed-in-lieu of foreclosure is initially recorded at the lower of cost or fair value, less estimated selling costs and is included in other assets on the consolidated balance sheet. Chargeoffs recorded at the time of acquisition are charged to the ACL. Thereafter, decreases in the property’s estimated fair value are charged to earnings and credited to a valuation allowance and subsequent recoveries in fair value are credited to earnings and charged to the valuation allowance. Such adjustments to earnings are included in other noninterest expense along with any additional property maintenance costs incurred in owning the property. Rental income received from tenants of other real estate owned is included in other noninterest income. Long-term Assets Premises and equipment, intangible assets, BOLI and other long-term assets, if any, are reviewed for impairment when events indicate that their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value. Loan Commitments and Related Financial Instruments Financial instruments include off-balance sheet credit instruments, such as commitments to make loans, commercial letters of credit and standby letters of credit. The face amount of these items represents the exposure to loss, before considering collateral held or ability to repay. The Bank estimates credit losses on off-balance sheet credit exposures by considering the likelihood of an outstanding commitment converting into an outstanding loan and applying historical loss factors used on similar portfolio segments, unless the obligation is unconditionally cancellable by the Bank. The ACL on off-balance sheet credit exposures is recorded in the line item “Accrued expenses and other liabilities” in the consolidated balance sheet and is adjusted as a provision for credit loss expense which is included in the line item “other noninterest expense” in the consolidated statements of income. Off-balance sheet credit instruments are recorded on the balance sheet when they are funded or drawn down. Derivatives The Corporation records cash flow hedges at the inception of a derivative contract based on management’s intentions and belief as to the likely effectiveness of the hedge. Cash flow hedges represent a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability. For a cash flow hedge, the gain or loss on the derivative is recorded in OCI and is reclassified into earnings in the same period during which the hedged transaction affects earnings. The changes in the fair value of a derivative that is not highly effective in hedging the expected cash flows of the hedged item are recognized immediately as interest expense in the consolidated statements of income. Net cash settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in noninterest income or noninterest expense. Cash flows from hedges are classified in the consolidated statements of cash flows in the same manner as the items being hedged. The Corporation formally documents the relationship between derivatives and hedged items, as well as the risk management objective and the strategy for undertaking hedge transactions at the inception of the hedging relationship. This documentation includes linking cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Corporation also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used are highly effective in offsetting changes in cash flows of the hedged item. The Corporation discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in cash flows of the hedged item, the derivative is settled or terminated, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm or treatment of the derivative as a hedge is no longer appropriate or intended. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as interest expense. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that were accumulated in OCI are amortized into earnings over the same periods which the hedged transactions will affect earnings. Checking Deposits The Bank’s commercial checking accounts generally have a related noninterest-bearing sweep account. The sole purpose of the sweep accounts is to reduce the reserve balances that the Bank is required to maintain with the FRBNY, and thereby increase funds available for investment. Although the sweep accounts are classified as savings accounts for regulatory purposes, they are included in checking deposits in the accompanying consolidated balance sheets. Income Taxes A current tax liability or asset is recognized for the estimated taxes payable or refundable on tax returns for the current year. A deferred tax liability or asset is recognized for the estimated future tax effects attributable to temporary differences and carryforwards. The measurement of deferred tax assets is reduced, if necessary, by the amount of any tax benefits that, based on available evidence, are not expected to be realized. The measurement of current and deferred tax liabilities and assets is based on provisions of the enacted tax law. The effects of future changes in tax laws or rates are not considered. The Corporation recognizes interest and/or penalties related to income tax matters in noninterest income or noninterest expense as appropriate. Retirement Plans Pension expense is the sum of service cost, interest cost, amortization of actuarial gains and losses and plan expenses, net of the expected return on plan assets and participant contributions. The service cost component of pension expense is included in salaries and employee benefits on the consolidated statement of income. All other components of pension expense are included in other noninterest income. Employee 401(k) plan expense is equal to the amount of the Corporation’s matching contributions and is included in salaries and employee benefits in the consolidated statements of income. Loss Contingencies Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Stockholders’ Equity Earnings Per Share . The Corporation calculates basic and diluted earnings per share (“EPS”) using the treasury stock method. Basic EPS excludes the dilutive effect of outstanding stock options and restricted stock units (“RSUs”) and is computed by dividing net income allocated to common stockholders by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if outstanding stock options and RSUs were converted into shares of common stock that then shared in the earnings of the Corporation. Diluted EPS is computed by dividing net income allocated to common stockholders by the weighted average number of common shares and dilutive stock options and RSUs. 25,519 and 6,122 RSUs were excluded from the calculation of EPS at December 31, 2020 and 2018, respectively, because their inclusion would be anti-dilutive. There were no anti-dilutive stock options or RSUs at December 31, 2019. Other than the stock options and RSUs described in “Note I – Stock-Based Compensation”, the Corporation has no securities that could be converted into common stock nor does the Corporation have any contracts that could result in the issuance of common stock. Stock-based Compensation The Corporation’s stock-based compensation plans are described in “Note I – Stock-Based Compensation.” Compensation cost is determined for stock options and RSUs issued to employees and non-employee directors based on the grant date fair value of the award. Compensation expense for RSUs is recognized over the applicable performance or service period, which is usually the vesting period, or the period from the grant date to the participant’s eligible retirement date, whichever is shorter. Compensation expense is adjusted at the end of the performance period, if applicable, to reflect the actual number of shares of the Corporation’s common stock into which the RSUs will be converted. Compensation expense for stock options is recognized over the five year vesting period or the period from the grant date to the participant’s eligible retirement date, whichever is shorter. The Corporation accounts for forfeitures as they occur. Comprehensive Income Comprehensive income includes net income and OCI. OCI includes revenues, expenses, gains and losses that under GAAP are included in comprehensive income but excluded from net income. OCI for the Corporation consists of net unrealized holding gains or losses on available-for-sale securities and derivative instruments and changes in the funded status of the Bank’s defined benefit pension plan, all net of related income taxes. Accumulated OCI is recognized as a separate component of stockholders’ equity. The components of OCI and the related tax effects are as follows: (in thousands) 2020 2019 2018 Change in net unrealized holding gains (losses) on available-for-sale securities: Change arising during the period $ 6,099 $ 14,156 $ ( 18,891 ) Reclassification adjustment for losses (gains) included in net income (1) ( 2,556 ) ( 14 ) 10,406 3,543 14,142 ( 8,485 ) Tax effect 1,063 4,242 ( 2,569 ) 2,480 9,900 ( 5,916 ) Change in funded status of pension plan: Unrecognized net gain (loss) arising during the period 1,571 3,173 ( 4,316 ) Amortization of net actuarial loss included in pension expense (2) — 352 — 1,571 3,525 ( 4,316 ) Tax effect 470 1,083 ( 1,312 ) 1,101 2,442 ( 3,004 ) Change in unrealized loss on derivative instruments: Amount of loss recognized during the period ( 4,835 ) ( 4,116 ) ( 1,607 ) Reclassification adjustment for net interest expense included in net income (3) 3,968 827 477 ( 867 ) ( 3,289 ) ( 1,130 ) Tax effect ( 261 ) ( 982 ) ( 341 ) ( 606 ) ( 2,307 ) ( 789 ) Other comprehensive income (loss) $ 2,975 $ 10,035 $ ( 9,709 ) (1) Represents net realized gains and losses arising from the sale of available-for-sale securities. These net realized gains and losses are included in the consolidated statements of income in the line item “Net gains (losses) on sales of securities.” See “Note B – Investment Securities” for the income tax expense or benefit related to these net realized gains and losses, which is included in the consolidated statements of income in the line item “Income tax expense.” (2) Represents the amortization of net actuarial loss relating to the Corporation’s defined benefit pension plan. This item is a component of net periodic pension cost (see “Note J – Retirement Plans”) and included in the consolidated statements of income in the line item “Other noninterest income.” (3) Represents the net interest expense recorded from derivative transactions and included in the consolidated statements of income under “Interest expense.” The following sets forth the components of accumulated OCI, net of tax: Current Period Change due to Other Balance Comprehensive Balance (in thousands) 12/31/19 Income (Loss) 12/31/20 Unrealized holding gains (losses) on available-for-sale securities $ 6,945 $ 2,480 $ 9,425 Unrealized actuarial losses on pension plan ( 3,254 ) 1,101 ( 2,153 ) Unrealized loss on derivative instruments ( 3,096 ) ( 606 ) ( 3,702 ) Accumulated other comprehensive income (loss), net of tax $ 595 $ 2,975 $ 3,570 Operating Segments While management monitors the revenue streams of the Bank’s various products and services, the identifiable segments are not material and operations are managed and financial performance is evaluated on a company-wide basis. Accordingly, all of the financial operations of the Bank are aggregated in one reportable operating segment. Investment Management Division Assets held in a fiduciary capacity are not assets of the Corporation and, accordingly, are not included in the accompanying consolidated financial statements. The Investment Management Division records fees on the accrual basis. Reclassifications When appropriate, items in the prior year financial statements are reclassified to conform to the current period presentation. Impact of Issued But Not Yet Effective Accounting Standards The pronouncements discussed in this section are not intended to be an all-inclusive list, but rather only those pronouncements that could potentially have an impact on the Corporation’s financial position, results of operations or disclosures. In August 2018, the FASB issued ASU 2018-14 “Changes to the Disclosure Requirements for Defined Benefit Plans.” The ASU modifies certain disclosure requirements pertaining to defined benefit plans as part of the FASB’s disclosure framework project intended to improve the effectiveness of disclosures in the notes to financial statements. ASU 2018-14 is effective for fiscal years ending after December 15, 2020. Early adoption is permitted. The adoption of the ASU may modify the Corporation’s disclosures but will not impact its financial position or results of operations.

There were no holdings of securities of any one issuer, other than the U.S. government and its agencies, in an amount greater than 10% of stockholders’ equity at December 31, 2020 and 2019. Securities With Unrealized Losses. The following tables set forth securities with unrealized losses at December 31, 2020 and 2019 presented by length of time the securities had been in a continuous unrealized loss position. 2020 Less than 12 Months 12 Months or More Total (in thousands) Fair Value Unrealized Loss Fair Value Unrealized Loss Fair Value Unrealized Loss Pass-through mortgage securities $ 1,871 $ ( 4 ) $ — $ — $ 1,871 $ ( 4 ) Collateralized mortgage obligations 24,970 ( 51 ) — — 24,970 ( 51 ) Corporate bonds — — 113,080 ( 5,920 ) 113,080 ( 5,920 ) Total temporarily impaired $ 26,841 $ ( 55 ) $ 113,080 $ ( 5,920 ) $ 139,921 $ ( 5,975 ) 2019 State and municipals $ 6,662 $ ( 83 ) $ 5,084 $ ( 156 ) $ 11,746 $ ( 239 ) Pass-through mortgage securities 5,287 ( 14 ) 4,084 ( 25 ) 9,371 ( 39 ) Collateralized mortgage obligations 30,886 ( 259 ) — — 30,886 ( 259 ) Corporate bonds 51,020 ( 980 ) 64,810 ( 2,190 ) 115,830 ( 3,170 ) Total temporarily impaired $ 93,855 $ ( 1,336 ) $ 73,978 $ ( 2,371 ) $ 167,833 $ ( 3,707 ) Following is a discussion of unrealized losses by type of security, none of which are considered impaired at December 31, 2020 and 2019. Pass-through Mortgage Securities At December 31, 2020, one pass-through mortgage security of approximately $ 1.9 million had an unrealized loss of $ 4,000 . This security was issued by a U.S. government-sponsored agency and is considered high investment grade. The decline in fair value is attributable to changes in interest rates and not credit quality. The issuer continues to make timely principal and interest payments on the bond. The Bank does not have the intent to sell this security and it is likely that it will not be required to sell the security before its anticipated recovery. The fair value is expected to recover as the bond approaches maturity. Collateralized Mortgage Obligations At December 31, 2020, collateralized mortgage obligations of approximately $ 25.0 million had an unrealized loss of $ 51,000 . These securities were issued by U.S. government-sponsored agencies and are considered high investment grade. The decline in fair value is attributable to changes in interest rates and not credit quality. The issuers continue to make timely principal and interest payments on the bonds. The Bank does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery. The fair value is expected to recover as the bonds approach maturity. Corporate Bonds At December 31, 2020, approximately $ 113.1 million of corporate bonds had an unrealized loss of $ 5.9 million. The corporate bonds represent senior unsecured debt obligations of six of the largest U.S. based financial institutions, including JPMorgan Chase, Bank of America, Citigroup, Goldman Sachs, Morgan Stanley, and Wells Fargo. Each of the corporate bonds has a stated maturity of ten years and matures in 2028. The bonds provided a fixed interest rate for a period of two years or three years and then reset quarterly based on the ten year constant maturity swap rate. During the fourth quarter of 2020, corporate bonds with a current fair value of $ 82.4 million began to reprice and had a weighted average yield of 1.21 % at December 31, 2020. During the fourth quarter of 2021, corporate bonds with current fair values of $ 30.7 million and a current weighted average yield of 5.10 % will begin to reprice on a quarterly basis. Each of the financial institutions is considered upper medium investment grade and rated A3 or higher. The decline in fair value is attributable to an increase in credit spreads, a decline in interest rates and the illiquid nature of the securities. The Bank does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery. Each of these financial institutions has diversified revenue streams, is well capitalized and continue to make timely interest payments. Management evaluates the quarterly financial statements of each company to determine if full payment of principal and interest is in doubt and does not believe there is any impairment at December 31, 2020. Sales of Available-for-Sale Securities. Sales of available-for-sale securities were as follows: (in thousands) 2020 2019 2018 Proceeds $ 64,453 $ 21,983 $ 263,994 Gains $ 2,556 $ 138 $ 300 Losses — ( 124 ) ( 10,706 ) Net gain (loss) $ 2,556 $ 14 $ ( 10,406 ) The income tax expense (benefit) related to these net realized gains (losses) was $ 766,000 , $ 4,000 and ($ 2,907,000 ) in 2020, 2019 and 2018, respectively, and is included in the consolidated statements of income in the line item “Income tax expense.” Sales of Held-to-Maturity Securities. The Bank did no t have any securities classified as held-to-maturity in 2020. During 2019 and 2018, the Bank did no t sell any securities that were classified as held-to-maturity. Maturities. The following table sets forth by maturity the amortized cost and fair value of the Bank’s state and municipal securities and corporate bonds at December 31, 2020 based on the earlier of their stated maturity or, if applicable, their pre-refunded date. The remaining securities in the Bank’s investment securities portfolio are mortgage-backed securities, consisting of pass-through mortgage securities and collateralized mortgage obligations. Although these securities are expected to have substantial periodic repayments they are reflected in the table below in aggregate amounts. (in thousands) Amortized Cost Fair Value Available-for-Sale Securities: Within one year $ 9,518 $ 9,560 After 1 through 5 years 77,694 80,408 After 5 through 10 years 240,070 239,537 After 10 years 139,978 147,786 Mortgage-backed securities 182,006 185,431 $ 649,266 $ 662,722

Q-factors assessing the risks associated with these modifications, higher charges resulting from Q-factors derived from current conditions and reasonable and supportable forecasts and increases in historical loss rates were the key drivers in determining the provision in 2020. These charges were offset in part by the decline in loan balances for most loan pools . Aging of Loans . The following tables present the aging of loans past due and loans in nonaccrual status by class of loans.

Accrued interest receivable from loans totaled $ 9,745,000 and $ 8,409,000 at December 31, 2020 and 2019, respectively, and is included in the line item “Other assets” on the consolidated balance sheets. COVID-19 Loan Modifications. During the second and third quarters of 2020, the Bank provided payment deferrals in the form of loan modifications to borrowers experiencing financial disruption and economic hardship as a result of the pandemic. As of December 31, 2020, all such loans have resumed making payment and are current except for seven loans that were charged-off totaling $ 440,000 and one loan that was 30 to 89 days past due in the amount of $ 41,000 . Additionally, three loans totaling $ 862,000 were in nonaccrual status at year end. Payments received from borrowers for COVID-19 loan modifications are first applied to interest accrued during the deferral period until such interest is recovered and then toward their contractual repayment schedule. Under the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), these modifications are not considered TDRs. Troubled Debt Restructurings. A restructuring constitutes a TDR when it includes a concession by the Bank and the borrower is experiencing financial difficulty. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. The Bank performs the evaluation under its internal underwriting policy, taking into consideration the relief from TDR accounting provided by the CARES Act. The following table presents information about loans modified in TDRs during the year ended December 31, 2018. The Bank did not modify any loans in TDRs during 2020 and 2019. Outstanding Recorded Investment Interest Rates (dollars in thousands) Number of Loans Pre- Modification Post- Modification Pre- Modification Post- Modification 2018: Residential mortgages - closed end 1 $ 432 $ 472 5.86 % 4.50 % Consumer and other 1 350 350 6.50 % 6.50 % 2 $ 782 $ 822 In 2018, the Bank consolidated an unsecured business line of credit, residential mortgage and home equity line of credit to a single borrower into a new first lien residential mortgage. The restructured residential mortgage resulted in a below market interest rate and extended term. Also in 2018, the Bank modified two consumer loans to a single borrower into one loan. The term of the restructured loan was extended for 12 months and the post-modification interest rate was lower than the current market rate for new debt with similar risk. At December 31, 2019 and 2018, the Bank had a reserve of $ 14,000 and $ 16,000 , respectively, allocated to specific TDRs. No ACL was allocated to specific troubled debt restructurings at December 31, 2020. The Bank had no commitments to lend additional amounts to loans that were classified as troubled debt restructurings. There were no TDRs for which there was a payment default during 2020, 2019 and 2018 that were modified during the 12 month period prior to default. A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms. Risk Characteristics. Credit risk within the Bank’s loan portfolio primarily stems from factors such as changes in the borrower’s financial condition, credit concentrations, changes in collateral values, economic conditions including those arising from the pandemic, rent regulation and environmental contamination of properties securing mortgage loans. The Bank’s commercial loans, including those secured by real estate mortgages, are primarily made to small and medium-sized businesses. Such loans sometimes involve a higher degree of risk than those to larger companies because such businesses may have shorter operating histories, higher debt-to-equity ratios and may lack sophistication in internal record keeping and financial and operational controls. In addition, most of the Bank’s loans are made to businesses and consumers on Long Island and in the boroughs of New York City (“NYC”), and a large percentage of these loans are mortgage loans secured by properties located in those areas. The primary sources of repayment for residential and commercial mortgage loans include employment and other income of the borrowers, the businesses of the borrowers and cash flows from the underlying properties. In the case of multifamily mortgage loans, a substantial portion of the underlying properties are rent stabilized or rent controlled. These sources of repayment are dependent on, among other things, the strength of the local economy. In addition, t he pandemic continues to present substantial challenges for the Bank and its customers. These challenges may result in higher drawdowns by customers on the Bank’s lending commitments, a deterioration in collateral values and higher past due and nonaccrual loans, TDRs and credit losses. Credit Quality Indicators. The Bank categorizes loans into risk categories based on relevant information about the borrower’s ability to service their debt including, but not limited to, current financial information for the borrower and any guarantors, payment experience, credit underwriting documentation, public records, due diligence checks and current economic trends. Management analyzes loans individually and classifies them using risk rating matrices consistent with regulatory guidance as follows. Watch: The borrower’s cash flow has a high degree of variability and subject to economic downturns. Liquidity is strained and the ability of the borrower to access traditional sources of credit is diminished. Special Mention: The borrower has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or in the Bank’s credit position at some future date. Special mention assets are not adversely classified and do not expose the Bank to risk sufficient to warrant adverse classification. Substandard: Loans are inadequately protected by the current sound worth and paying capacity of the borrower or 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 Bank will sustain some loss if the deficiencies are not corrected. Doubtful: Loans have all the inherent weaknesses of those classified 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. Risk ratings on commercial and industrial loans and commercial mortgages are initially assigned during the underwriting process and affirmed as part of the approval process. The ratings are periodically reviewed and evaluated based on borrower contact, credit department review or independent loan review. The Bank's loan risk rating and review policy establishes requirements for the annual review of commercial real estate and commercial and industrial loans. The requirements include details of the scope of coverage and selection process based on loan-type and risk rating. Among other things, at least 80% of the recorded investment of commercial real estate loans as of December 31 of the prior year must be reviewed annually. Lines of credit are also reviewed annually at each proposed reaffirmation. The frequency of the review of other loans is determined by minimum principal balance thresholds and the Bank’s ongoing assessments of the borrower’s condition. Residential mortgage loans, revolving home equity lines and other consumer loans are initially evaluated utilizing the borrower’s credit score. A credit score is a tool used in the Bank’s loan approval process, and a minimum score of 680 is generally required for new loans. Credit scores for each borrower are updated at least annually. However, regardless of credit score, loans may be classified, criticized or placed on management’s watch list if relevant information comes to light. The following tables present the amortized cost basis of loans by class of loans and risk rating for the periods indicated. Loans shown as Pass are all loans other than those risk rated Watch, Special Mention, Substandard or Doubtful.

Regulatory Matters [Abstract]
Regulatory Matters	NOTE H – REGULATORY MATTERS Minimum Regulatory Capital Requirements . The Corporation and the Bank are subject to the Basel III regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action (“PCA”) regulations, involve quantitative measures of assets, liabilities and certain off-balance sheet items calculated under regulatory accounting practices. Failure to meet the minimum capital requirements can result in certain mandatory and possibly additional discretionary actions by the regulators that, if undertaken, could have a direct material effect on the financial statements of the Corporation and Bank. The most recent regulatory notifications categorized the Bank as well capitalized under the PCA provisions and there are no conditions or events since that notification that management believes have changed that category. In accordance with the Economic Growth, Regulatory Relief, and Consumer Protection Act, the federal banking agencies adopted, effective January 1, 2020, a final rule whereby financial institutions and financial institution holding companies that have less than $10 billion in total consolidated assets and meet other qualifying criteria, including a leverage ratio of greater than 9% (“qualifying community banking organizations”), are eligible to opt into a community bank leverage ratio (“CBLR”) framework. Qualifying community banking organizations that elect to use the CBLR framework and that maintain a leverage ratio of greater than 9% are considered to have satisfied the generally applicable risk-based and leverage capital requirements in the agencies’ capital rules and will be considered to have met the well capitalized ratio requirements under the PCA statutes. The agencies reserved the authority to disallow the use of the CBLR framework by a financial institution or holding company, based on the risk profile of the organization. The Corporation and the Bank elected to adopt the CBLR framework. As a qualifying community banking organization, the Corporation and the Bank may opt out of the CBLR framework in any subsequent quarter by completing its regulatory agency reporting using the traditional capital rules. In April 2020, the federal banking agencies issued interim final rules pursuant to section 4012 of the CARES Act , temporarily lowering the CBLR requirement to 8.00% through the end of 2020, 8.50% for calendar year 2021 and 9.00% in 2022. The CARES Act also provides that, during the same time period, if a qualifying community banking organization falls no more than 1% below the CBLR, it will have a two-quarter grace period to satisfy the CBLR. The Corporation and the Bank exclude accumulated OCI components from Tier 1 and Total regulatory capital. During 2020, the Corporation and the Bank elected the optional five-year transition period provided by the federal banking agencies for recognizing the regulatory capital impact of the implementation of CECL. The Corporation’s and the Bank’s actual and required capital amounts and ratios under the CBLR rules at December 31, 2020 and the Basel III rules at December 31, 2019 are presented in the tables below. 2020 Actual Capital To Be Well Capitalized Under CBLR Framework (dollars in thousands) Amount Ratio Amount Ratio Tier 1 capital to average assets: Consolidated $ 405,819 9.97 % $ 325,634 8.00 % Bank 406,038 9.98 325,511 8.00 2019 Actual Capital Minimum Capital Adequacy Requirement Minimum To Be Well Capitalized Under PCA Provisions (dollars in thousands) Amount Ratio Amount Ratio Amount Ratio Tier 1 capital to average assets: Consolidated $ 388,293 9.42 % $ 164,964 4.00 % N/A N/A Bank 388,150 9.42 164,885 4.00 $ 206,106 5.00 % Common equity tier 1 capital to risk weighted assets: Consolidated 388,293 14.93 117,048 4.50 N/A N/A Bank 388,150 14.93 117,001 4.50 169,002 6.50 Tier 1 capital to risk weighted assets: Consolidated 388,293 14.93 156,064 6.00 N/A N/A Bank 388,150 14.93 156,002 6.00 208,003 8.00 Total capital to risk weighted assets: Consolidated 417,757 16.06 208,085 8.00 N/A N/A Bank 417,614 16.06 208,003 8.00 260,003 10.00 Other Matters. A source of funds for dividend payments to shareholders is dividends received from the Bank. Banking regulations limit the amount of dividends that may be paid by the Bank without prior approval of regulatory agencies. Under these regulations, the amount of dividends that the Bank may pay in any calendar year is limited to the current year’s net profits, combined with the retained net profits of the preceding two years , subject to the minimum capital requirements described above. During 2021, the Bank could, without prior approval, declare dividends of approximately $ 6,264,000 plus any 2021 net profits retained to the date of the dividend declaration. Regulation D of the Board of Governors of The Federal Reserve System requires banks to maintain reserves against certain deposit balances. The Bank’s average reserve requirement for 2020 was approximately $ 7,403,000 .

Retirement Plans [Abstract]
Retirement Plans	NOTE J – RETIREMENT PLANS The Bank has a 401(k) plan and a defined benefit pension plan (“Pension Plan” or “Plan”). Employees are immediately eligible to participate in the 401(k) plan provided they are at least 18 years of age. Participants may elect to contribute, on a tax-deferred basis, up to 100% of gross compensation, as defined, subject to the limitations of Section 401(k) of the Internal Revenue Code. The Bank may, at its sole discretion, make matching contributions to each participant's account based on the amount of the participant's tax deferred contributions. Participants are fully vested in their elective contributions and, after five years of participation in the 401(k) plan, are fully vested ( 20 % vesting per year) in the matching contributions, if any, made by the Bank. The Bank’s expense for matching contributions was $ 524,000 , $ 459,000 and $ 486,000 for 2020, 2019 and 2018, respectively. An internal management committee (the “Committee”) oversees the affairs of the Pension Plan and acts as named fiduciary. The Committee has retained Vanguard Group, Inc., including its subsidiaries and affiliates (“Vanguard”), to act as discretionary investment agent, trustee and custodian for the Plan. Vanguard has formulated investment recommendations customized to meet the Committee’s objectives and, after approval by the Committee, such investment recommendations are incorporated into the investment guidelines and policies contained in the investment management agreement between the Bank and Vanguard (the “Investment Management Agreement”). The Committee utilizes a formal Investment Policy Statement which includes, among other things, the investment guidelines and policies contained in the Investment Management Agreement. The Investment Policy Statement is periodically revised by the Committee as deemed appropriate. Employees are eligible to participate in the Pension Plan after attaining 21 years of age and completing 12 full months of service. Pension benefits are generally based on a percentage of average annual compensation during the period of creditable service. The Bank makes contributions to the Pension Plan which, when taken together with participant contributions equal to 2 % of their compensation, will be sufficient to fund these benefits. The Bank’s funding method, the unit credit actuarial cost method, is consistent with the funding requirements of applicable federal laws and regulations which set forth both minimum required and maximum tax deductible contributions. Employees become fully vested after four years of participation in the Pension Plan ( no vesting occurs during the four year period). Significant Actuarial Assumptions . The following table sets forth the significant actuarial assumptions used to determine the benefit obligation at December 31, 2020, 2019 and 2018 and the benefit cost for each of the Plan years then ended. 2020 2019 2018 Weighted average assumptions used to determine the benefit obligation at year end: Discount rate 2.67 % 3.55 % 4.53 % Rate of increase in compensation levels 3.50 % 3.50 % 3.50 % Weighted average assumptions used to determine net pension cost: Discount rate 3.55 % 4.53 % 3.93 % Rate of increase in compensation levels 3.50 % 3.50 % 3.50 % Expected long-term rate of return on plan assets 5.50 % 5.50 % 5.50 % The decrease in the discount rate from 3.55 % in 2019 to 2.67 % in 2020 increased the projected benefit obligation at December 31, 2020 by approximately $ 6,121,000 . In calculating the benefit obligation at December 31, 2020, the mortality table previously utilized, RP-2014 Healthy Annuitant/Employee Mortality Table with Projection Scale MP-2019, was adjusted to reflect Scale MP-2020. The updated mortality table decreased the projected benefit obligation at December 31, 2020 by approximately $ 350,000 . The decrease in the discount rate from 4.53 % in 2018 to 3.55 % in 2019 increased the projected benefit obligation at December 31, 2019 by approximately $ 5,399,000 . In calculating the benefit obligation at December 31, 2019, the mortality table previously utilized, RP-2014 Healthy Annuitant/Employee Mortality Table with Projection Scale MP-2018, was adjusted to reflect Scale MP-2019. The updated mortality table decreased the projected benefit obligation at December 31, 2019 by approximately $ 199,000 . The increase in the discount rate from 3.93 % in 2017 to 4.53 % in 2018 decreased the projected benefit obligation at December 31, 2018 by approximately $ 3,093,000 . In calculating the benefit obligation at December 31, 2018, the mortality table previously utilized, RP-2014 Healthy Annuitant/Employee Mortality Table with Projection Scale MP-2017, was adjusted to reflect Scale MP-2018. The updated mortality table decreased the projected benefit obligation at December 31, 2018 by approximately $ 133,000 . Net Pension Cost. The following table sets forth the components of net periodic pension cost. (in thousands) 2020 2019 2018 Service cost plus expected expenses and net of expected plan participant contributions $ 1,647 $ 1,268 $ 1,369 Interest cost 1,647 1,785 1,587 Expected return on plan assets ( 3,557 ) ( 3,001 ) ( 3,275 ) Amortization of net actuarial loss — 352 — Net pension cost (credit) $ ( 263 ) $ 404 $ ( 319 ) The components of net pension credit other than the service cost component were included in the line item “Other noninterest income” in the consolidated statements of income. The service cost component was included in the line item “Salaries and employee benefits” in the consolidated statements of income. No portion of the net actuarial loss for the defined benefit plan will be amortized from accumulated OCI into net periodic pension cost in 2021. Funded Status of the Plan . The following table sets forth the change in the projected benefit obligation and Plan assets for each year and, as of the end of each year, the funded status of the Plan and accumulated benefit obligation. (in thousands) 2020 2019 2018 Change in projected benefit obligation: Projected benefit obligation at beginning of year $ 47,471 $ 40,470 $ 41,384 Service cost 1,844 1,447 1,533 Interest cost 1,647 1,785 1,587 Benefits paid ( 1,919 ) ( 1,985 ) ( 1,574 ) Assumption changes 5,771 5,200 ( 3,226 ) Experience loss and other 828 554 766 Projected benefit obligation at end of year 55,642 47,471 40,470 Change in fair value of plan assets: Fair value of plan assets at beginning of year 65,746 55,624 60,536 Actual return on plan assets 11,657 11,854 ( 3,563 ) Employer contributions — — — Plan participant contributions 383 356 333 Benefits paid ( 1,919 ) ( 1,985 ) ( 1,574 ) Expenses ( 116 ) ( 103 ) ( 108 ) Fair value of plan assets at end of year 75,751 65,746 55,624 Funded status at end of year $ 20,109 $ 18,275 $ 15,154 Accumulated benefit obligation $ 51,541 $ 44,544 $ 38,042 During 2020, the Bank did no t make a contribution to the Plan and the Bank has no minimum required pension contribution for the Plan year ending September 30, 2021. It’s maximum tax-deductible contribution for the tax year beginning January 1, 2021 is $ 1,363,000 . The contribution the Bank will make in 2021, if any, has not yet been determined. Plan Assets. The objective for the Plan’s assets is to generate long-term investment returns from both income and capital appreciation which outpaces the rate of inflation, while maintaining sufficient liquidity to ensure the Plan’s ability to pay all anticipated benefit and expense obligations when due. The Plan will maintain a de minimis amount of cash equivalents, with the remaining assets allocated across two broadly-defined financial asset categories: (1) equity, both domestic and international; and (2) fixed income of various durations and issuer type. The goal of the equity allocation is to supplement the Bank’s contributions to the Plan when the Plan is underfunded and increase surplus when the Plan is overfunded. The fixed income component will include longer-duration bonds designed to match and hedge the characteristics of the Plan’s liabilities. Cash equivalents, under normal circumstances, will be temporary holdings for the purpose of paying expenses and monthly benefits. For fixed income investments: (1) the minimum average credit quality shall be investment grade (Standard & Poor’s BBB or Moody’s Baa) or higher; and (2) no more than 5 % of the portfolio may be invested in securities with ratings below investment grade, and none may be rated below investment grade at the time of purchase. Reasonable precautions are taken to avoid excessive concentrations to protect the portfolio against unfavorable outcomes within an asset class. Specifically, the following guidelines are in place:  With the exception of fixed income investments explicitly guaranteed by the U.S. government, no single investment security shall represent more than 5 % of total Plan assets; and  With the exception of passively managed investment vehicles seeking to match the returns of broadly diversified market indices or diversified investment vehicles chosen specifically to hedge the interest rate risk embedded in Plan liabilities, no single investment pool or investment company (mutual fund) shall comprise more than 10 % of total plan assets. The portfolio will be rebalanced to the target asset allocation, if needed, no less often than quarterly. Unless expressly authorized in writing by the Committee, the following investing activities are prohibited:  Purchasing securities on margin;  Pledging or hypothecating securities, except for loans of securities that are fully collateralized;  Purchasing or selling derivative securities for speculation or leverage; and  Engaging in investment strategies that have the potential to amplify or distort the risk of loss beyond a level that is reasonably expected given the objectives of the portfolio. The Plan’s actual asset allocations, target allocations and expected long-term rates of return by asset category at December 31, 2020 and 2019 are set forth in the tables that follow. December 31, 2020 Target Allocation Percentage of Plan Assets Weighted Average Expected Long-term Rates of Return Cash equivalents 0 % - 1 % 0.2 % < 1.00 % Equity mutual funds 20 % - 30 % 26.5 % 6.2 % to 8.6 % Fixed income mutual funds 70 % - 80 % 73.3 % 2.1 % to 3.3 % 100.0 % 3.2 % to 4.7 % December 31, 2019 Cash equivalents 0 % - 1 % 0.2 % < 1.00 % Equity mutual funds 20 % - 30 % 26.4 % 6.2 % to 8.7 % Fixed income mutual funds 70 % - 80 % 73.4 % 3.3 % to 4.4 % 100.0 % 4.1 % to 5.5 % The ranges for the weighted average expected long-term rates of return for equity funds, bond funds and total plan assets set forth in the preceding table represent expected 25 th to 75 th percentile returns provided by Vanguard. For these purposes Vanguard utilizes a proprietary capital markets model (the “model”) developed and maintained by Vanguard’s primary investment research and advice teams. The model forecasts distributions of future returns for a wide array of broad asset classes. The theoretical and empirical foundation of the model is that the returns of various asset classes reflect the compensation investors require for bearing different types of systematic risk. At the core of the model are estimates of the dynamic statistical relationship between risk factors and asset returns, obtained from statistical analysis based on available historical monthly financial and economic data. At December 31, 2020, the equity and fixed income components of Plan assets consist of the following Vanguard institutional funds: Equity  Vanguard Total Stock Market Index Fund (VITSX). This fund seeks to track the performance of the Center for Research in Security Prices (CRSP) U.S. Total Market Index. The fund is passively managed using index sampling and consists of large, small and mid-cap equity securities diversified across growth and value styles.  Vanguard Total International Stock Index Fund (VTSNX). This fund seeks to track the performance of the Financial Times Stock Exchange (FTSE) Global All Cap ex U.S. Index. The fund is passively managed and includes broad exposure across developed and emerging non-U.S. equity markets. Fixed Income  Vanguard Long-Term Investment-Grade Fund (VWETX). This fund seeks high and sustainable current income. Investments are selected using a fundamental, bottom-up credit selection process and consist of long-term, high-quality bonds broadly diversified by issuer and industry sector.  Vanguard Long-Term Treasury Index Fund (VLGIX). This fund seeks to track the performance of the Bloomberg Barclays U.S. Long Treasury Bond Index. The fund is passively managed using index sampling and includes long-term, fixed income securities issued by the U.S. Treasury. Fair Value of Plan Assets. The fair value of the Plan assets at December 31, 2020 and 2019, by asset category, is summarized below.

Commitments And Contingent Liabilities [Abstract]
Commitments And Contingent Liabilities	NOTE L – COMMITMENTS AND CONTINGENT LIABILITIES Financial Instruments With Off-Balance-Sheet Risk. In the normal course of business, the Bank enters into various types of off-balance-sheet arrangements to meet the financing needs of its customers. These off-balance-sheet financial instruments include commitments to extend credit, standby letters of credit and commercial letters of credit. These instruments involve varying degrees of credit risk in excess of the amount recognized in the consolidated balance sheets and expose the Bank to credit loss in the event of nonperformance by the Bank’s customers. The Bank's exposure to credit loss is represented by the contractual notional amount of these instruments. The Bank uses the same credit policies in making commitments to extend credit, and generally uses the same credit policies for letters of credit, as it does for on-balance sheet instruments such as loans. At December 31, 2019 and 2018, financial instruments whose contract amounts represent credit risk are as follows: 2020 2019 (in thousands) Fixed Rate Variable Rate Fixed Rate Variable Rate Commitments to extend credit $ 37,085 $ 215,581 $ 23,914 $ 163,898 Standby letters of credit 4,246 — 3,704 — A commitment to extend credit is a legally binding agreement to lend to a customer as long as there is no violation of any condition established in the contract. Unused home equity, small business and commercial lines of credit are a large component of the Bank’s variable rate loan commitments. Since some of the commitments to extend credit and letters of credit are expected to expire without being drawn upon and, with respect to unused lines of credit, can be frozen, reduced or terminated by the Bank based on the financial condition of the borrower, the total commitment amounts do not necessarily represent future cash requirements. Home equity lines generally expire ten years from their date of origination and small business lines generally have a three year term. Other real estate loan commitments generally expire within 60 days and commercial line commitments generally expire within one year . At December 31, 2020, the Bank’s fixed rate loan commitments are to make loans with interest rates ranging from 2.50 % to 4.15 % and maturities of ten years or more. The amount of collateral obtained, if any, by the Bank upon extension of credit is based on management’s credit evaluation of the borrower. Collateral held varies but may include mortgages on commercial and residential real estate, securities, deposit accounts with the Bank or other financial institutions and security interests in business assets and equipment. Standby letters of credit are conditional commitments issued by the Bank to assure the performance or financial obligations of a customer to a third party. The Bank's standby letters of credit extend through September 2031. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loans to customers. The Bank generally holds collateral and/or obtains personal guarantees supporting these commitments. The extent of collateral held for these commitments at December 31, 2020 varied from 50 % to 100 % of the contractual notional amount of each instrument, with the average amount of collateral totaling 94 % of the aggregate outstanding notional amount. Standby letters of credit are considered financial guarantees and are recorded at fair value. Employment Agreements. At December 31, 2020, the Corporation’s chief executive officer and executive vice presidents, collectively referred to as the senior executives, had employment agreements with the Corporation under which they are entitled to severance compensation in the event that their employment is terminated without cause or they terminate their employment following an event constituting Good Reason, as defined. The chief executive officer’s employment agreement has a term of three years beginning January 1, 2020. Each of the other senior executives has an employment agreement with a term of two years and various effective dates. These two year and three year employment agreements automatically renew for an additional period of one year on January 1 of each year unless the Corporation gives written notice of non-renewal at least 30 days prior to such date. Notwithstanding the foregoing, each of these employment agreements expire on December 31 of the calendar year in which the executive attains normal retirement age (“Retirement Age Termination Date”), which for these purposes is age 65. At the appropriate time and at its option, the Corporation can extend the employment agreements for two years beyond their retirement age termination dates. The current aggregate annual salaries provided for in these employment agreements is $ 2,295,000 . Litigation. From time to time the Corporation may be a named defendant in legal actions incidental to the business. For some of these actions there is always a possibility that the Corporation will sustain a financial loss. There was no outstanding litigation at December 31, 2020.

Fair Value Of Financial Instruments [Abstract]
Fair Value Of Financial Instruments	NOTE M – FAIR VALUE OF FINANCIAL INSTRUMENTS Financial Instruments Recorded at Fair Value . When measuring fair value, the Corporation uses a fair value hierarchy, which is designed to maximize the use of observable inputs and minimize the use of unobservable inputs. The hierarchy involves three levels of inputs that may be used to measure fair value: Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Corporation has the ability to access at the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as 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; or inputs other than quoted prices that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect the Corporation’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. The Corporation deems transfers between levels of the fair value hierarchy to have occurred on the date of the event or change in circumstance that caused the transfer. There were no transfers between levels of the fair value hierarchy in either 2020 or 2019. The fair values of the Corporation’s financial assets and liabilities measured at fair value on a recurring basis are set forth in the table that follows. The fair values of available-for-sale securities are determined on a recurring basis using matrix pricing (Level 2 inputs). Matrix pricing, which is a mathematical technique widely used in the industry to value debt securities, does not rely exclusively on quoted prices for the specific securities but rather on the relationship of such securities to other benchmark quoted securities. Where no significant other observable inputs were available, Level 3 inputs were used. The fair values of interest rate swaps are based on valuation models using observable market data as of the measurement date resulting in a Level 2 classification. Fair Value Measurements Using: (in thousands) Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) December 31, 2020: Financial Assets: Available-for-Sale Securities: State and municipals $ 364,211 $ — $ 362,776 $ 1,435 Pass-through mortgage securities 131,720 — 131,720 — Collateralized mortgage obligations 53,711 — 53,711 — Corporate bonds 113,080 — 113,080 — $ 662,722 $ — $ 661,287 $ 1,435 Financial Liabilities: Derivative - interest rate swaps $ 5,285 $ — $ 5,285 $ — December 31, 2019: Financial Assets: Available-for-Sale Securities: State and municipals $ 382,143 $ — $ 380,299 $ 1,844 Pass-through mortgage securities 61,372 — 61,372 — Collateralized mortgage obligations 138,199 — 138,199 — Corporate bonds 115,830 — 115,830 — $ 697,544 $ — $ 695,700 $ 1,844 Financial Liabilities: Derivative - interest rate swap $ 4,418 $ — $ 4,418 $ — There were no assets measured at fair value on a nonrecurring basis at December 31, 2020 and 2019. Financial Instruments Not Recorded at Fair Value. Fair value estimates are made at a specific point in time. Such estimates are generally subjective in nature and dependent upon a number of significant assumptions associated with each financial instrument or group of similar financial instruments, including estimates of discount rates, liquidity, risks associated with specific financial instruments, estimates of future cash flows, and relevant available market information. Changes in assumptions could significantly affect the estimates. In addition, fair value estimates do not reflect the value of anticipated future business, premiums or discounts that could result from offering for sale at one time the Corporation’s entire holdings of a particular financial instrument, or the income tax consequences of realizing gains or losses on the sale of financial instruments. The following table sets forth the carrying amounts and estimated fair values of financial instruments that are not recorded at fair value in the Corporation’s financial statements at December 31, 2020 and 2019.

Revenue From Contracts With Customers [Abstract]
Revenue From Contracts With Customers	NOTE N – REVENUE FROM CONTRACTS WITH CUSTOMERS The noninterest income section of the consolidated statements of income includes the following types of revenues earned from the Bank's contracts with customers. Investment Management Division Revenues. The Bank holds customer assets in a fiduciary capacity and provides various services, including trust account services, estate settlement, custody and asset management. The services are performed for customers over time, requiring a time-based measure of progress. Fees are assessed based on market values of customer assets held or under management as of a certain point in time, and income cannot be estimated prior to the end of the measurement period. Volatility in equity and other market values will impact the amount of revenue that will be earned. Fees are generally earned and collected on a monthly or quarterly basis, accrued to income as earned and included in the consolidated statements of income in the line item "Investment Management Division income." Deposit Account Revenues. Fees are earned and collected on a monthly basis for account maintenance and activity-based service charges on deposit accounts. The services are performed for customers over time, requiring a time-based measure of progress. Customers may be required to maintain minimum balances and average balances. Additional fees may also be earned for overdrafts, replacement of debit cards, bill payment, lockbox services and ACH services, among others, and are earned and collected as transactions take place. All deposit account fees are accrued to income as earned, either monthly or at the point of sale, and included in the consolidated statements of income in the line item "Service charges on deposit accounts." Transaction and Branch Service Fees. The following revenue streams are components of “Other noninterest income” on the consolidated statements of income. These components totaled $ 1,950,000 , $ 2,078,000 and $ 2,089,000 for the years ended December 31, 2020, 2019 and 2018, respectively. Other items included in “Other noninterest income,” such as BOLI income, non-service components of net pension cost, real estate tax refunds and gains on sales of fixed assets are outside of the scope of ASC 606. Debit/Credit Card Revenues . The Bank earns a fee when its customers use their debit or credit cards in point-of-sale transactions. These fees are generally known as interchange fees. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recorded daily, concurrently with the transaction processing services provided to the cardholder. Branch Services Revenues. The Bank charges fees for safe deposit box rentals, wire transfers, money orders, checkbook printing, official checks and ATM usage. Fees are earned, collected and generally recorded as revenue when the service is provided. Investment Advisory Services. The Bank provides branch space to a third party who sells financial products to the Bank’s customers and pays commissions to the Bank based on the products sold. Commissions are variable and based on the market values of financial assets sold. Commissions are accrued to income as earned and collected.

Derivatives [Abstract]
Derivatives	NOTE O – DERIVATIVES As part of its asset liability management activities, the Corporation utilizes interest rate swaps to help manage its interest rate risk position. The notional amount of an interest rate swap does not represent the amount exchanged by the parties. The exchange of cash flows is determined by reference to the notional amount and the other terms of the interest rate swap agreements. The Bank entered into an interest rate swap with a notional amount totaling $ 150 million on May 22, 2018 and a second interest rate swap with a notional amount of $ 50 million on January 17, 2019. The interest rate swaps were designated as cash flow hedges of certain FHLB advances and brokered CDs. The swaps were determined to be fully effective during the period presented and therefore no amount of ineffectiveness has been included in net income. The aggregate fair value of the swaps is recorded in other liabilities, with changes in fair value net of related income taxes recorded in OCI. The amount included in accumulated OCI would be reclassified to current earnings should the hedges no longer be considered effective. The Corporation expects the hedges to remain fully effective during the remaining term of the swaps. The following table summarizes information about the interest rate swaps designated as cash flow hedges. December 31, 2020 December 31, 2019 Notional amount $ 200 million $ 200 million Weighted average fixed pay rate 2.83 % 2.83 % Weighted average 3-month LIBOR receive rate 0.22 % 2.04 % Weighted average maturity 1.06 Years 2.06 Years Interest expense recorded on the swap transactions, which totaled $ 3,968,000 , $ 827,000 and $ 477,000 for 2020, 2019 and 2018, respectively, is recorded as a component of interest expense in the consolidated statements of income. Amounts reported in accumulated OCI related to the swaps will be reclassified to interest expense as interest payments are made on the Bank’s variable rate liabilities. During 2020, 2019 and 2018, the Corporation had $ 3,968,000 $ 827,000 and $ 477,000 , respectively, of reclassifications to interest expense. During the next 12 months, the Corporation estimates that $ 1,994,000 will be reclassified as an increase to interest expense. The following table presents the net gains (losses) recorded in the consolidated statements of income and the consolidated statements of comprehensive income relating to the interest rate swaps for the years indicated. Year Ended December 31, (in thousands) 2020 2019 2018 Interest rate contracts: Amount of loss recognized in OCI (effective portion) $ ( 4,835 ) $ ( 4,116 ) $ ( 1,607 ) Amount of loss reclassified from OCI to interest expense 3,968 827 477 Amount of loss recognized in other noninterest income (ineffective portion) — — — The following table reflects the amounts relating to interest rate swaps included in the consolidated balance sheet at December 31, 2020 and 2019.

The Bank’s agreement with its interest rate swap counterparty sets forth minimum collateral posting thresholds. If the termination value of the swaps is a net asset position, the counterparty may be required to post collateral against its obligations to the Bank under the agreement. However, if the termination value of the swaps is a net liability position, the Bank may be required to post collateral to the counterparty. At December 31, 2020, the Bank is in compliance with the collateral posting provisions to its counterparty. The total amount of collateral posted was approximately $ 6.0 million. If the Bank had breached any of these provisions at December 31, 2020, it could have been required to settle its obligations under the agreement at the termination value.

The accounting and reporting policies of the Corporation reflect banking industry practice and conform to generally accepted accounting principles (“GAAP”) in the United States. The following is a summary of the Corporation’s significant accounting policies. In preparing the consolidated financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported asset and liability balances, revenue and expense amounts, and the disclosures provided, including disclosure of contingent assets and liabilities, based on available information. Actual results could differ significantly from those estimates. Information available which could affect these judgements include, but are not limited to, changes in interest rates, changes in the performance of the economy including the economic impact of the COVID-19 pandemic (“pandemic”) on both the allowance and provision for credit losses, and changes in the financial condition of borrowers.
Adoption Of New Accounting Standards	Adoption of New Accounting Standards In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13 “Measurement of Credit Losses on Financial Instruments (Topic 326)” (“CECL”) . This standard changes the methodology used to determine the allowance for loan losses from an incurred loss model to a current expected credit loss model. The CECL model requires the Bank to maintain at each periodic reporting date an allowance for credit losses (“ACL” or “allowance”) in an amount that is equal to its estimate of expected lifetime credit losses on all financial assets measured at amortized cost, including loan receivables, held-to-maturity debt securities and certain off-balance sheet credit exposures. Management adopted ASU 2016-13, as amended, on January 1, 2020 using the modified retrospective approach for all financial assets measured at amortized cost and off-balance sheet credit commitments. Results for reporting periods beginning on or after January 1, 2020 are presented under Accounting Standards Codification (“ASC”) 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. On January 1, 2020, the Corporation recorded a net decrease to retained earnings of $ 2,325,000 , net of tax effect of $ 993,000 , for the implementation of ASC 326, with offsetting increases of $ 2,888,000 and $ 430,000 to the ACL on loans and off-balance sheet credit exposures, respectively. The following table illustrates the impact of ASC 326.

Management adopted ASU 2018-13 on January 1, 2020. See Note M “Fair Value of Financial Instruments” for disclosures required by ASU 2018-13.
Cash And Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash and deposits with other financial institutions that generally mature within 90 days.
Investment Securities	Investment Securities Current accounting standards require that investment securities be classified as held-to-maturity, available-for-sale or trading. The trading category is not applicable to any securities in the Bank's portfolio because the Bank does not buy or hold debt or equity securities principally for the purpose of selling in the near term. Held-to-maturity securities, or debt securities which the Bank has the intent and ability to hold to maturity, are reported at amortized cost. Available-for-sale securities, or debt securities which are neither held-to-maturity securities nor trading securities, are reported at fair value, with unrealized gains and losses, net of the related income tax effect, included in other comprehensive income (loss) (“OCI”). Equity securities, if any, are carried at fair value, with changes in fair value reported in net income. Equity securities without readily determinable fair values are carried at cost, minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment. Interest income includes amortization or accretion of purchase premium or discount. Premiums and discounts on securities are amortized or accreted using the level-yield method. Prepayments are anticipated for mortgage-backed securities. Premiums on municipal securities are amortized to the earlier of the stated maturity date or the first call date, while discounts on municipal securities are accreted to the stated maturity date. Realized gains and losses on the sale of securities are determined using the specific identification method. Management measures expected credit losses on held-to-maturity debt securities, if any, on a collective basis by major security type. Accrued interest receivable on held-to maturity debt securities is excluded from the estimate of credit losses. For available-for-sale securities in an unrealized loss position, management first evaluates whether the decline in fair value has resulted from an actual or estimated credit loss event. Management considers, among other factors, the extent to which fair value is less than amortized cost, changes to the rating of the security, and adverse conditions specifically related to the security. If this assessment indicates that a credit loss is likely, management then assesses whether it has the intent to sell the security or more likely than not will be required to sell the security before recovery of its amortized cost and determines the present value of cash flows expected to be collected from the security as compared to the amortized cost basis of the security. If the present value of the cash flows expected to be collected is less than the amortized cost basis, an allowance is recorded for the estimated 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 is recognized in OCI. Accrued interest receivable on available-for-sale securities is excluded from the estimate of credit losses.
Loans Held-For-Sale	Loans Held-for-Sale Loans held-for-sale are carried at the lower of cost or fair value. Any subsequent declines in fair value below the initial carrying value are recorded as a valuation allowance established through a charge to noninterest income.
Loans And Allowance For Credit Losses	Loans and Allowance for Credit Losses Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost, net of the ACL. Amortized cost is the principal balance outstanding plus or minus net deferred loan costs and fees. Accrued interest receivable is reported in “Other assets” on the consolidated balance sheets and is excluded from the estimate of credit losses. Interest on loans is credited to income based on the principal amount outstanding. Direct loan origination costs, net of loan origination fees, are deferred and recognized in interest income using the level-yield method without anticipating prepayments. The past due status of a loan is based on the contractual terms in the loan agreement. Unless a loan is well secured and in the process of collection, the accrual of interest income is discontinued when a loan becomes 90 days past due as to principal or interest payments. The accrual of interest income on a loan is also discontinued when it is determined that the borrower will not be able to make principal and interest payments according to the contractual terms of the current loan agreement. When the accrual of interest income is discontinued on a loan, any accrued but unpaid interest is reversed against current period income. Interest received on nonaccrual loans is applied to the outstanding principal balance until the loans qualify for return to an accrual status, if ever. Return to an accrual status occurs when all the principal and interest amounts contractually past due are brought current and all future payments are reasonably assured. The ACL is a valuation account that is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on the Bank’s loan portfolio. The allowance is established through provisions for credit losses charged against income. When available information confirms that specific loans, or portions thereof, are uncollectible, these amounts are charged against the ACL, and subsequent recoveries, if any, are credited to the allowance. Management identifies loans in the Bank’s portfolio that must be individually evaluated for loss due to disparate risk characteristics or information suggesting that the Bank will be unable to collect all the principal and interest due. For loans individually evaluated, a specific reserve is estimated based on either the fair value of collateral or the discounted value of expected future cash flows. In estimating the fair value of real estate collateral, management utilizes appraisals or evaluations adjusted for costs to dispose and a distressed sale adjustment, if needed. Estimating the fair value of collateral other than real estate is also subjective in nature and sometimes requires difficult and complex judgements. Determining expected future cash flows can be more subjective than determining fair values. Expected future cash flows could differ significantly, both in timing and amount, from the cash flows actually received over the loan’s remaining life. Individually evaluated loans are excluded from the estimation of credit losses for the pooled portfolio. Troubled debt restructurings (“TDRs”) are individually evaluated for loss and generally reported at the present value of estimated future cash flows using the loan’s effective rate at inception. However, if a TDR is considered to be a collateral dependent loan, the loan is reported at the fair value of the collateral. For loans collectively evaluated for credit loss, management segregates its loan portfolio into eleven distinct pools, certain of which are combined in reporting loans outstanding by class of loans: (1) commercial and industrial; (2) small business credit scored; (3) multifamily; (4) owner-occupied; (5) other commercial real estate; (6) construction and land development; (7) closed end residential mortgage; (8) revolving home equity; (9) consumer; (10) municipal loans; and (11) Small Business Administration (“SBA”) Paycheck Protection Program (“PPP”) loans. Historical loss information from the Bank’s own loan portfolio from December 31, 2007 to present provides a basis for management’s assessment of expected credit losses. The choice of a historical look-back period that begins in 2007 covers an entire economic cycle and impacts the average historical loss rates used to calculate the final ACL. Due to the extensive historical loss data available, management has determined that the vintage approach is the most appropriate method of measuring the historical loss component of credit losses inherent in its portfolio for most of its loan pools. For the revolving home equity and small business credit scored pools, the migration approach was selected to measure historical losses since contractual lives are not readily discernable and balances can fluctuate throughout the life of the lines. Finally, no historical loss method was applied to the SBA PPP loan pool which is a new pool with no loss experience and is 100% guaranteed by the federal government. Management believes that the methods selected fairly reflect the historical loss component of expected losses inherent in the Bank’s loan portfolio. However, since future losses could vary significantly from those experienced in the past, on a quarterly basis management adjusts its historical loss experience to reflect current and forecasted conditions. In doing so, management considers a variety of general qualitative and quantitative factors (“Q-factors”) and then subjectively determines the weight to assign to each in estimating losses. Qualitative characteristics include, among others, differences in underwriting standards, policies, lending staff and environmental risks. Management also considers whether further adjustments to historical loss information are needed to reflect the extent to which current conditions and reasonable and supportable forecasts over a one year to two year forecasting horizon differ from the conditions that existed during the historical loss period. These quantitative adjustments reflect changes to relevant data such as changes in unemployment rates, GDP, vacancies, home prices, average growth in pools of loans, delinquencies or other factors associated with the financial assets. The allowance for SBA PPP loans represents an estimate of potential loss due to documentation and processing deficiencies. The immediate reversion method is applied for periods beyond the forecasting horizon. The Bank’s ACL allocable to pools of loans that are collectively evaluated for credit loss results primarily from these qualitative and quantitative adjustments to historical loss experience. Because of the nature of the Q-factors and the degree of judgement involved in assessing their impact, management’s resulting estimate of losses may not accurately reflect current and future losses in the portfolio. The ACL is an amount that management currently believes will be adequate to absorb current expected credit losses in the Bank’s loan portfolio. The process for estimating credit losses and determining the ACL as of any balance sheet date is subjective in nature and requires material estimates. Actual results could differ significantly from those estimates.
Transfers Of Financial Assets	Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Corporation, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Corporation does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Bank Premises And Equipment And Operating Leases	Bank Premises and Equipment and Operating Leases Land is carried at cost. Other bank premises and equipment are carried at cost less accumulated depreciation and amortization. Buildings are depreciated using the straight-line method over their estimated useful lives, which range from 31 to 40 years. Building and leasehold improvements are depreciated using the straight-line method over the remaining lives of the buildings or leases, as applicable, or their estimated useful lives, whichever is shorter. The lives of the respective leases range from five years to twenty years . Furniture, fixtures and equipment are depreciated using the straight-line method over their estimated useful lives, which range from three years to ten years . Premises and equipment held-for-sale, if any, is included in “Other assets” on the Corporation’s consolidated balance sheet and carried at the lower of cost or fair value. The Bank determines if an arrangement is a lease at inception and recognizes a right-of-use (“ROU”) asset and lease liability at the commencement date based on the present value of lease payments over the lease term. As most of the Bank’s leases do not provide an implicit interest rate, the Bank uses its incremental borrowing rate to determine the present value of the lease payments. The Bank’s ROU asset and lease liability may include options to extend the lease when it is reasonably certain that the Bank will exercise that option. Lease expense is recognized on a straight-line basis over the lease term.
Bank-Owned Life Insurance	Bank-owned Life Insurance The Bank is the owner and beneficiary of insurance policies on the lives of certain officers. Bank-owned life insurance (“BOLI”) is recorded at the amount that can be realized under the contract at the balance sheet date, which is the cash surrender value adjusted for other charges or amounts due that are probable at settlement, if any.
Restricted Stock	Restricted Stock The Bank is a member of and is required to own stock in the Federal Home Loan Bank of New York (“FHLBNY”) and the Federal Reserve Bank of New York (“FRBNY”). The amount of FHLBNY stock held is based on membership and the level of FHLBNY advances. The amount of FRBNY stock held is based on the Bank’s capital and surplus balances. These stocks do not have a readily determinable fair value, are carried at cost, classified as restricted stock and periodically evaluated for impairment based on the prospects for the ultimate recovery of cost. Cash dividends, if any, are reported as interest income on taxable investment securities.
Other Real Estate Owned	Other Real Estate Owned Real estate acquired through foreclosure or by deed-in-lieu of foreclosure is initially recorded at the lower of cost or fair value, less estimated selling costs and is included in other assets on the consolidated balance sheet. Chargeoffs recorded at the time of acquisition are charged to the ACL. Thereafter, decreases in the property’s estimated fair value are charged to earnings and credited to a valuation allowance and subsequent recoveries in fair value are credited to earnings and charged to the valuation allowance. Such adjustments to earnings are included in other noninterest expense along with any additional property maintenance costs incurred in owning the property. Rental income received from tenants of other real estate owned is included in other noninterest income.
Long-term Assets	Long-term Assets Premises and equipment, intangible assets, BOLI and other long-term assets, if any, are reviewed for impairment when events indicate that their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value.
Loan Commitments And Related Financial Instruments	Loan Commitments and Related Financial Instruments Financial instruments include off-balance sheet credit instruments, such as commitments to make loans, commercial letters of credit and standby letters of credit. The face amount of these items represents the exposure to loss, before considering collateral held or ability to repay. The Bank estimates credit losses on off-balance sheet credit exposures by considering the likelihood of an outstanding commitment converting into an outstanding loan and applying historical loss factors used on similar portfolio segments, unless the obligation is unconditionally cancellable by the Bank. The ACL on off-balance sheet credit exposures is recorded in the line item “Accrued expenses and other liabilities” in the consolidated balance sheet and is adjusted as a provision for credit loss expense which is included in the line item “other noninterest expense” in the consolidated statements of income. Off-balance sheet credit instruments are recorded on the balance sheet when they are funded or drawn down.
Derivatives	Derivatives The Corporation records cash flow hedges at the inception of a derivative contract based on management’s intentions and belief as to the likely effectiveness of the hedge. Cash flow hedges represent a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability. For a cash flow hedge, the gain or loss on the derivative is recorded in OCI and is reclassified into earnings in the same period during which the hedged transaction affects earnings. The changes in the fair value of a derivative that is not highly effective in hedging the expected cash flows of the hedged item are recognized immediately as interest expense in the consolidated statements of income. Net cash settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in noninterest income or noninterest expense. Cash flows from hedges are classified in the consolidated statements of cash flows in the same manner as the items being hedged. The Corporation formally documents the relationship between derivatives and hedged items, as well as the risk management objective and the strategy for undertaking hedge transactions at the inception of the hedging relationship. This documentation includes linking cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Corporation also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used are highly effective in offsetting changes in cash flows of the hedged item. The Corporation discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in cash flows of the hedged item, the derivative is settled or terminated, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm or treatment of the derivative as a hedge is no longer appropriate or intended. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as interest expense. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that were accumulated in OCI are amortized into earnings over the same periods which the hedged transactions will affect earnings.
Checking Deposits	Checking Deposits The Bank’s commercial checking accounts generally have a related noninterest-bearing sweep account. The sole purpose of the sweep accounts is to reduce the reserve balances that the Bank is required to maintain with the FRBNY, and thereby increase funds available for investment. Although the sweep accounts are classified as savings accounts for regulatory purposes, they are included in checking deposits in the accompanying consolidated balance sheets.
Income Taxes	Income Taxes A current tax liability or asset is recognized for the estimated taxes payable or refundable on tax returns for the current year. A deferred tax liability or asset is recognized for the estimated future tax effects attributable to temporary differences and carryforwards. The measurement of deferred tax assets is reduced, if necessary, by the amount of any tax benefits that, based on available evidence, are not expected to be realized. The measurement of current and deferred tax liabilities and assets is based on provisions of the enacted tax law. The effects of future changes in tax laws or rates are not considered. The Corporation recognizes interest and/or penalties related to income tax matters in noninterest income or noninterest expense as appropriate.
Retirement Plans	Retirement Plans Pension expense is the sum of service cost, interest cost, amortization of actuarial gains and losses and plan expenses, net of the expected return on plan assets and participant contributions. The service cost component of pension expense is included in salaries and employee benefits on the consolidated statement of income. All other components of pension expense are included in other noninterest income. Employee 401(k) plan expense is equal to the amount of the Corporation’s matching contributions and is included in salaries and employee benefits in the consolidated statements of income.
Loss Contingencies	Loss Contingencies Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated.
Stockholders’ Equity	Stockholders’ Equity Earnings Per Share . The Corporation calculates basic and diluted earnings per share (“EPS”) using the treasury stock method. Basic EPS excludes the dilutive effect of outstanding stock options and restricted stock units (“RSUs”) and is computed by dividing net income allocated to common stockholders by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if outstanding stock options and RSUs were converted into shares of common stock that then shared in the earnings of the Corporation. Diluted EPS is computed by dividing net income allocated to common stockholders by the weighted average number of common shares and dilutive stock options and RSUs. 25,519 and 6,122 RSUs were excluded from the calculation of EPS at December 31, 2020 and 2018, respectively, because their inclusion would be anti-dilutive. There were no anti-dilutive stock options or RSUs at December 31, 2019. Other than the stock options and RSUs described in “Note I – Stock-Based Compensation”, the Corporation has no securities that could be converted into common stock nor does the Corporation have any contracts that could result in the issuance of common stock.
Stock-based Compensation	Stock-based Compensation The Corporation’s stock-based compensation plans are described in “Note I – Stock-Based Compensation.” Compensation cost is determined for stock options and RSUs issued to employees and non-employee directors based on the grant date fair value of the award. Compensation expense for RSUs is recognized over the applicable performance or service period, which is usually the vesting period, or the period from the grant date to the participant’s eligible retirement date, whichever is shorter. Compensation expense is adjusted at the end of the performance period, if applicable, to reflect the actual number of shares of the Corporation’s common stock into which the RSUs will be converted. Compensation expense for stock options is recognized over the five year vesting period or the period from the grant date to the participant’s eligible retirement date, whichever is shorter. The Corporation accounts for forfeitures as they occur.
Comprehensive Income	Comprehensive Income Comprehensive income includes net income and OCI. OCI includes revenues, expenses, gains and losses that under GAAP are included in comprehensive income but excluded from net income. OCI for the Corporation consists of net unrealized holding gains or losses on available-for-sale securities and derivative instruments and changes in the funded status of the Bank’s defined benefit pension plan, all net of related income taxes. Accumulated OCI is recognized as a separate component of stockholders’ equity. The components of OCI and the related tax effects are as follows: (in thousands) 2020 2019 2018 Change in net unrealized holding gains (losses) on available-for-sale securities: Change arising during the period $ 6,099 $ 14,156 $ ( 18,891 ) Reclassification adjustment for losses (gains) included in net income (1) ( 2,556 ) ( 14 ) 10,406 3,543 14,142 ( 8,485 ) Tax effect 1,063 4,242 ( 2,569 ) 2,480 9,900 ( 5,916 ) Change in funded status of pension plan: Unrecognized net gain (loss) arising during the period 1,571 3,173 ( 4,316 ) Amortization of net actuarial loss included in pension expense (2) — 352 — 1,571 3,525 ( 4,316 ) Tax effect 470 1,083 ( 1,312 ) 1,101 2,442 ( 3,004 ) Change in unrealized loss on derivative instruments: Amount of loss recognized during the period ( 4,835 ) ( 4,116 ) ( 1,607 ) Reclassification adjustment for net interest expense included in net income (3) 3,968 827 477 ( 867 ) ( 3,289 ) ( 1,130 ) Tax effect ( 261 ) ( 982 ) ( 341 ) ( 606 ) ( 2,307 ) ( 789 ) Other comprehensive income (loss) $ 2,975 $ 10,035 $ ( 9,709 ) (1) Represents net realized gains and losses arising from the sale of available-for-sale securities. These net realized gains and losses are included in the consolidated statements of income in the line item “Net gains (losses) on sales of securities.” See “Note B – Investment Securities” for the income tax expense or benefit related to these net realized gains and losses, which is included in the consolidated statements of income in the line item “Income tax expense.” (2) Represents the amortization of net actuarial loss relating to the Corporation’s defined benefit pension plan. This item is a component of net periodic pension cost (see “Note J – Retirement Plans”) and included in the consolidated statements of income in the line item “Other noninterest income.” (3) Represents the net interest expense recorded from derivative transactions and included in the consolidated statements of income under “Interest expense.” The following sets forth the components of accumulated OCI, net of tax: Current Period Change due to Other Balance Comprehensive Balance (in thousands) 12/31/19 Income (Loss) 12/31/20 Unrealized holding gains (losses) on available-for-sale securities $ 6,945 $ 2,480 $ 9,425 Unrealized actuarial losses on pension plan ( 3,254 ) 1,101 ( 2,153 ) Unrealized loss on derivative instruments ( 3,096 ) ( 606 ) ( 3,702 ) Accumulated other comprehensive income (loss), net of tax $ 595 $ 2,975 $ 3,570
Operating Segments	Operating Segments While management monitors the revenue streams of the Bank’s various products and services, the identifiable segments are not material and operations are managed and financial performance is evaluated on a company-wide basis. Accordingly, all of the financial operations of the Bank are aggregated in one reportable operating segment.
Investment Management Division	Investment Management Division Assets held in a fiduciary capacity are not assets of the Corporation and, accordingly, are not included in the accompanying consolidated financial statements. The Investment Management Division records fees on the accrual basis.
Reclassifications	Reclassifications When appropriate, items in the prior year financial statements are reclassified to conform to the current period presentation.
Impact Of Issued But Not Yet Effective Accounting Standards	Impact of Issued But Not Yet Effective Accounting Standards The pronouncements discussed in this section are not intended to be an all-inclusive list, but rather only those pronouncements that could potentially have an impact on the Corporation’s financial position, results of operations or disclosures. In August 2018, the FASB issued ASU 2018-14 “Changes to the Disclosure Requirements for Defined Benefit Plans.” The ASU modifies certain disclosure requirements pertaining to defined benefit plans as part of the FASB’s disclosure framework project intended to improve the effectiveness of disclosures in the notes to financial statements. ASU 2018-14 is effective for fiscal years ending after December 15, 2020. Early adoption is permitted. The adoption of the ASU may modify the Corporation’s disclosures but will not impact its financial position or results of operations.
