Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 1: Summary of Significant Accounting Policies Nature of Operations The accompanying consolidated financial statements include the accounts of Pathfinder Bancorp, Inc. (the “Company”) and its wholly owned subsidiary, Pathfinder Bank (the “Bank”). The Company is a Maryland corporation headquartered in Oswego, New York. On October 16, 2014, the Company completed its conversion from the mutual holding company structure and the related public offering and is now a stock holding company that is fully owned by the public. As a result of the conversion, the mutual holding company and former mid-tier holding company were merged into Pathfinder Bancorp, Inc. The primary business of the Company is its investment in Pathfinder Bank (the "Bank") which is 100% owned by the Company. The Bank has two wholly owned operating subsidiaries, Pathfinder Risk Management Company, Inc. (“PRMC”) and Whispering Oaks Development Corp. All significant inter-company accounts and activity have been eliminated in consolidation. Although the Company owns, through its subsidiary PRMC, 51% of the membership interest in FitzGibbons Agency, LLC (“FitzGibbons”), the Company is required to consolidate 100% of FitzGibbons within the consolidated financial statements. The 49% of which the Company does not own is accounted for separately as noncontrolling interests within the consolidated financial statements. The Company received $24.9 million in net proceeds from the sale of approximately 2.6 million shares of common stock as a result of the Conversion in October 2014. In October 2015, the Company executed the issuance of a $10.0 million non-amortizing Subordinated Loan and subsequently used those proceeds in February 2016 to substantially fund the full retirement of $13.0 million in SBLF Preferred stock. The Company received $19.6 million in net proceeds from the sale of 37,700 shares of common stock and 1,155,283 shares of preferred stock as a result of the Private Placement in May 2019. The Company has seven branch offices located in Oswego County, three branch offices in Onondaga County and one limited purpose office in Oneida County. The Company is primarily engaged in the business of attracting deposits from the general public in the Company’s market area, and investing such deposits, together with other sources of funds, in loans secured by commercial real estate, business assets, one-to-four family residential real estate and investment securities. Discussion of COVID-19 Pandemic A discussion of the effect of the COVID-19 pandemic on the operations of the Company is contained herein in Note 29. Use of Estimates in the Preparation of Consolidated Financial Statements The preparation of consolidated financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Management has identified the allowance for loan losses, deferred income taxes, pension obligations, the annual evaluation of the Company’s goodwill for possible impairment and the evaluation of investment securities for other than temporary impairment and the estimation of fair values for accounting and disclosure purposes to be the accounting areas that require the most subjective and complex judgments, and as such, could be the most subject to revision as new information becomes available. The Company is subject to the regulations of various governmental agencies. The Company also undergoes periodic examinations by the regulatory agencies which may subject it to further changes with respect to asset valuations, amounts of required loss allowances, and operating restrictions resulting from the regulators' judgments based on information available to them at the time of their examinations. Significant Group Concentrations of Credit Risk Most of the Company’s activities are with customers located primarily in Oswego and Onondaga counties of New York State. A large portion of the Company’s portfolio is centered in residential and commercial real estate. The Company closely monitors real estate collateral values and requires additional reviews of commercial real estate appraisals by a qualified third party for commercial real estate loans in excess of $400,000. All residential loan appraisals are reviewed by an individual or third party who is independent of the loan origination or approval process and was not involved in the approval of appraisers or selection of the appraiser for the transaction, and has no direct or indirect interest, financial or otherwise in the property or the transaction. Advertising The Company generally follows the policy of charging the costs of advertising to expense as incurred. Expenditures for new marketing and advertising material designs and/or media content, related to specifically-identifiable marketing campaigns are capitalized and expensed over the estimated life of the campaign. Such periods of time are generally 12-24 months in duration and do not exceed 36 months. Noncontrolling Interest Noncontrolling interest represents the portion of ownership and profit or loss that is attributable to the minority owners of FitzGibbons. Cash and Cash Equivalents Cash and cash equivalents include cash on hand, amounts due from banks and interest-bearing deposits (with original maturity of three months or less). Investment Securities The Company classifies investment securities as either available-for-sale or held-to-maturity. The Company does not hold any securities considered to be trading. Available-for-sale securities are reported at fair value, with net unrealized gains and losses reflected as a separate component of shareholders’ equity, net of the applicable income tax effect. Held-to-maturity securities are those that the Company has the ability and intent to hold until maturity and are reported at amortized cost. Gains or losses on investment security transactions are based on the amortized cost of the specific securities sold. Premiums and discounts on securities are amortized and accreted into income using the interest method over the period to maturity. The Company records its investment in marketable equity securities (“MES”) at fair value. Changes in the fair value of MES are recorded as additions to, or subtractions from, net income in the period that the change occurs. These changes in fair value are separately disclosed as gains (losses) on equity securities on the Consolidated Statements of Income. Note 4 to the consolidated financial statements includes additional information about the Company’s accounting policies with respect to the impairment of investment securities. Federal Home Loan Bank Stock Federal law requires a member institution of the Federal Home Loan Bank (“FHLB”) system to hold stock of its district FHLB according to a predetermined formula. The stock is carried at cost. Transfers of Financial Assets Transfers of financial assets, including sales of loans and loan participations, are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) 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 (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Loans The Company grants mortgage, commercial, municipal, and consumer loans to customers. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are stated at their outstanding unpaid principal balances, less the allowance for loan losses plus net deferred loan origination costs. The ability of the Company’s debtors to honor their contracts is dependent upon the real estate and general economic conditions in the market area. Interest income is generally recognized when income is earned using the interest method. Nonrefundable loan fees received and related direct origination costs incurred are deferred and amortized over the life of the loan using the interest method, resulting in a constant effective yield over the loan term. Deferred fees are recognized into income and deferred costs are charged to income immediately upon prepayment of the related loan. The loans receivable portfolio is segmented into residential mortgage, commercial and consumer loans. The residential mortgage segment consists of one-to-four family first-lien residential mortgages and construction loans. Commercial loans consist of the following classes: real estate, lines of credit, other commercial and industrial, and tax-exempt loans. Consumer loans include both home equity lines of credit and loans with junior liens and other consumer loans. Allowance for Loan Losses The allowance for loan losses represents management’s estimate of losses inherent in the loan portfolio as of the date of the statement of condition and it is recorded as a reduction of loans. The allowance is increased by the provision for loan losses, and decreased by charge-offs, net of recoveries. Loans deemed to be uncollectible are charged against the allowance for loan losses, and subsequent recoveries, if any, are credited to the allowance. All, or part, of the principal balance of loans receivable are charged off to the allowance as soon as it is determined that the repayment of all, or part, of the principal balance is highly unlikely. Non-residential consumer loans are generally charged off no later than 120 days past due on a contractual basis, unless productive collection efforts are providing results. Consumer loans may be charged off earlier in the event of bankruptcy, or if there is an amount that is deemed uncollectible. No portion of the allowance for loan losses is restricted to any individual loan product and the entire allowance is available to absorb any and all loan losses. The allowance for loan losses is maintained at a level considered adequate to provide for losses that can be reasonably anticipated. Management performs a quarterly evaluation of the adequacy of the allowance. The allowance is based on three major components which are; specific components for larger loans, recent historical losses and several qualitative factors applied to a general pool of loans, and an unallocated component. The first component is the specific component that relates to loans that are classified as impaired. For these loans, an allowance is established when the discounted cash flows or collateral value of the impaired loan is lower than the carrying value of that loan. The second or general component covers pools of loans, by loan class, not considered impaired, smaller balance homogeneous loans, such as residential real estate, home equity and other consumer loans. These pools of loans are evaluated for loss exposure first based on historical loss rates for each of these categories of loans. The ratio of net charge-offs to loans outstanding within each product class, over the most recent eight quarters, lagged by one quarter, is used to generate the historical loss rates. In addition, qualitative factors are added to the historical loss rates in arriving at the total allowance for loan loss need for this general pool of loans. The qualitative factors include changes in national and local economic trends, the rate of growth in the portfolio, trends of delinquencies and nonaccrual balances, changes in loan policy, and changes in lending management experience and related staffing. Each factor is assigned a value to reflect improving, stable or declining conditions based on management’s best judgment using relevant information available at the time of the evaluation. These qualitative factors, applied to each product class, make the evaluation inherently subjective, as it requires material estimates that may be susceptible to significant revision as more information becomes available. Adjustments to the factors are supported through documentation of changes in conditions in a narrative accompanying the allowance for loan loss analysis and calculation. As a result of the COVID-19 pandemic, the Company’s management extensively reviewed a broad array of econometric projections and the potential effect of changes in those projections on anticipated loan performance. As a result, certain qualitative factors were substantially modified during 2020 in order to determine the adequacy of the allowance for loan losses during the year and at December 31, 2020. The third or unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio and generally comprises less than 10% of the total allowance for loan loss. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and shortfalls on a case-by case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length and reason for the delay, the borrower’s prior payment record and the amount of shortfall in relation to what is owed. Impairment is measured by either the present value of the expected future cash flows discounted at the loan’s effective interest rate or the fair value of the underlying collateral, if the loan is collateral dependent. The majority of the Company’s loans utilize the fair value of the underlying collateral. The CARES Act, signed into law on March 27, 2020, provided financial assistance in various forms to both businesses and consumers. One of the technical provisions of the CARES Act was to allow financial institutions not to characterize loan modifications specifically related to the COVID-19 pandemic as TDRs although financial institutions must make impairment determinations for accounting purposes if certain impairment triggers are met. Notwithstanding the Bank’s policies with respect to impaired and potentially impaired loans, as discussed above, certain loans on deferred payment status were not classified as impaired or TDRs at December 31, 2020, as a result of the application of the provisions of the CARES Act. An allowance for loan loss is established for an impaired loan if its carrying value exceeds its estimated fair value. The estimated fair values of substantially all of the Company’s impaired loans are measured based on the estimated fair value of the loan’s collateral. For loans secured by real estate, estimated fair values are determined primarily through third-party appraisals, less costs to sell. Appraised values are discounted to arrive at the estimated selling price of the collateral, which is considered to be the estimated fair value. The discounts also include estimated costs to sell the property. For commercial and industrial loans secured by non-real estate collateral, such as accounts receivable, inventory and equipment, estimated fair values are determined based on the borrower’s financial statements, inventory reports, accounts receivable agings or equipment appraisals or invoices. Indications of value from these sources are generally discounted based on the age of the financial information or the quality of the assets. Large groups of homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual residential mortgage loans less than $300,000, home equity and other consumer loans for impairment disclosures, unless such loans are related to borrowers with impaired commercial loans or they are subject to a troubled debt restructuring agreement. Loans that are related to borrowers with impaired commercial loans or are subject to a troubled debt restructuring agreement are evaluated individually for impairment. Commercial loans whose terms are modified are classified as troubled debt restructurings if the Company grants such borrowers concessions and it is deemed that those borrowers are experiencing financial difficulty. Concessions granted under a troubled debt restructuring generally include but are not limited to a temporary reduction in the interest rate or an extension of a loan’s stated maturity date. Commercial loans classified as troubled debt restructurings are designated as impaired and evaluated individually as discussed above. The allowance calculation methodology includes further segregation of loan classes into risk rating categories. The borrower’s overall financial condition, repayment sources, guarantors and value of the collateral, if appropriate, are evaluated not less than annually for commercial loans or when credit deficiencies arise on all loans. Credit quality risk ratings include regulatory classifications of special mention, substandard, doubtful and loss. See Note 5 for a description of these regulatory classifications. In addition, Federal and State regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan losses and may require the Company to recognize additions to the allowance based on their judgments about information available to them at the time of their examination, which may not be currently available to management. Based on management’s comprehensive analysis of the loan portfolio, management believes the current level of the allowance for loan losses is adequate. Income Recognition on Impaired and Nonaccrual Loans With the exception of loans in deferral at December 31, 2020 as a result of COVID-19 pandemic-related factors, for all classes of loans receivable, the accrual of interest is discontinued when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about further collectability of principal or interest, even though the loan may be currently performing. A loan may remain on accrual status if it is either well secured or guaranteed and in the process of collection. When a loan is placed on nonaccrual status, unpaid interest is reversed and charged to interest income. Interest received on nonaccrual loans, including impaired loans, generally is either applied against principal or reported as interest income, according to management’s judgment as to the collectability of principal. Generally, loans are restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time, generally six months, and the ultimate collectability of the total contractual principal and interest is no longer in doubt. Nonaccrual troubled debt restructurings are restored to accrual status if principal and interest payments, under the modified terms, are current for six consecutive months after modification. For nonaccrual loans, when future collectability of the recorded loan balance is expected, interest income may be recognized on a cash basis. In the case where a nonaccrual loan had been partially charged off, recognition of interest on a cash basis is limited to that which would have been recognized on the recorded loan balance at the contractual interest rate. Cash interest receipts in excess of that amount are recorded as recoveries to the allowance for loan losses until prior charge-offs have been fully recovered. Off-Balance Sheet Credit Related Financial Instruments In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under standby letters of credit. Such financial instruments are recorded when they are funded. Premises and Equipment Premises and equipment are stated at cost, less accumulated depreciation. Depreciation is computed on a straight-line basis over the estimated useful lives of the related assets, ranging up to 40 years for premises and 10 years for equipment. Maintenance and repairs are charged to operating expenses as incurred. The asset cost and accumulated depreciation are removed from the accounts for assets sold or retired and any resulting gain or loss is included in the determination of income. Foreclosed Real Estate Physical possession of residential real estate property collateralizing a residential mortgage loan occurs when legal title is obtained upon completion of foreclosure or when the borrower conveys all interest in the property to satisfy the loan through completion of a deed-in-lieu of foreclosure or through a similar legal agreement. Properties acquired through foreclosure, or by deed-in-lieu of foreclosure, are recorded at their fair value less estimated costs to sell. Fair value is typically determined based on evaluations by third parties. Costs incurred in connection with preparing the foreclosed real estate for disposition are capitalized to the extent that they enhance the overall fair value of the property. Any write-downs on the asset’s fair value less costs to sell at the date of acquisition are charged to the allowance for loan losses. Subsequent write downs and expenses of foreclosed real estate are included as a valuation allowance and recorded in noninterest expense. Goodwill and Intangible Assets Goodwill represents the excess cost of an acquisition over the fair value of the net assets acquired. Goodwill is not amortized, but is evaluated annually or when there is a triggering event for impairment. Intangible assets, such as customer lists, are amortized over their useful lives, generally 15 years. Mortgage Servicing Rights Originated mortgage servicing rights are recorded at their fair value at the time of transfer of the related loans and are amortized in proportion to, and over the period of, estimated net servicing income or loss. The carrying value of the originated mortgage servicing rights is periodically evaluated for impairment or between annual evaluations under certain circumstances. Stock-Based Compensation Compensation costs related to share-based payment transactions are recognized based on the grant-date fair value of the stock-based compensation issued. Compensation costs are recognized over the period that an employee provides service in exchange for the award. Compensation costs related to the Employee Stock Ownership Plan are dependent upon the average stock price and the shares committed to be released to plan participants through the period in which income is reported. Retirement Benefits The Company has a non-contributory defined benefit pension plan that covered substantially all employees. On May 14, 2012, the Company informed its employees of its decision to freeze participation and benefit accruals under the plan, primarily to reduce some of the volatility in earnings that can accompany the maintenance of a defined benefit plan. The plan was frozen on June 30, 2012. Compensation earned by employees up to June 30, 2012 is used for purposes of calculating benefits under the plan but there will be no future benefit accruals after this date. Participants as of June 30, 2012 will continue to earn vesting credit with respect to their frozen accrued benefits as they continue to work. Pension expense under these plans is charged to current operations and consists of several components of net pension cost based on various actuarial assumptions regarding future experience under the plans. Gains and losses, prior service costs and credits, and any remaining transition amounts that have not yet been recognized through net periodic benefit cost are recognized in accumulated other comprehensive loss, net of tax effects, until they are amortized as a component of net periodic cost. Plan assets and obligations are measured as of the Company’s statement of condition date. The Company has unfunded deferred compensation and supplemental executive retirement plans for selected current and former employees and officers that provide benefits that cannot be paid from a qualified retirement plan due to Internal Revenue Code restrictions. These plans are nonqualified under the Internal Revenue Code, and assets used to fund benefit payments are not segregated from other assets of the Company, therefore, in general, a participant's or beneficiary's claim to benefits under these plans is as a general creditor. The Bank sponsors an Employee Stock Ownership Plan (“ESOP”) covering substantially all full time employees. The cost of shares issued to the ESOP but not committed to be released to the participants is presented in the consolidated statement of condition as a reduction of shareholders’ equity. ESOP shares are released to the participants on an annual basis in accordance with a predetermined schedule. The Company records ESOP compensation expense based on the shares committed to be released and allocated to the participant’s accounts multiplied by the average share price of the Company’s stock over the period. Dividends related to unallocated shares are recorded as compensation expense. Derivative Financial Instruments Derivatives are recorded on the statement of condition as assets and liabilities measured at their fair value. The accounting for changes in the fair value of a derivative depends on whether or not the derivative has been designated and qualifies as part of a hedging relationship. The Company acquires derivatives with the intent of designating and qualifying those instruments as part of hedging relationships to other balance sheet assets or liabilities. The specific accounting treatment for increases and decreases in the value of derivatives further depends upon the use of the specific derivatives. There are two primary types of interest rate derivatives that may be employed by the Company: • Fair Value Hedge - As a result of interest rate fluctuations, fixed-rate assets and liabilities will appreciate or depreciate in fair value over the course of their economic lives prior to maturity . When effectively hedged, this appreciation or depreciation will generally be offset by fluctuations in the fair value of derivative instruments that are linked to the hedged assets and liabilities. This strategy is referred to as a fair value hedge. For a fair value hedge, changes in the fair value of the derivative instrument and changes in the fair value of the hedged asset or liability are expected to substantially offset each other and these changes are recognized currently in earnings. • Cash Flow Hedge - Cash flows related to floating rate assets and liabilities will fluctuate with changes in the underlying rate index. When effectively hedged, the increases or decreases in cash flows related to the floating-rate asset or liability will generally be offset by changes in cash flows of the derivative instrumnets designated as a hedge. This strategy is referred to as a cash flow hedge. For a cash flow hedge, changes in the fair value of the derivative instrument, to the extent that it is effective, are recorded in other comprehensive income and subsequently reclassified to earnings as the hedged transaction impacts net income. Any ineffective portion of a cash flow hedge is recognized currently in earnings. Income Taxes Provisions for income taxes are based on taxes currently payable or refundable and deferred income taxes on temporary differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements. Deferred tax assets and liabilities are reported in the consolidated financial statements at currently enacted income tax rates applicable to the period in which the deferred tax assets and liabilities are expected to be realized or settled. Earnings Per Share Basic net income per share was calculated using the two-class method by dividing net income (less any dividends on participating securities) by the weighted average number of shares of common stock and participating securities outstanding for the period. Diluted earnings per share may include the additional effect of other securities, if dilutive, in which case the dilutive effect of such securities is calculated by applying either the two-class method or the Treasury Stock method to the assumed exercise or vesting of potentially dilutive common shares. The method yielding the more dilutive result is ultimately reported for the applicable period. Potentially dilutive common stock equivalents primarily consist of employee stock options and restricted stock units. Unallocated common shares held by the ESOP are not included in the weighted average number of common shares outstanding for purposes of calculating earnings per common share until they are committed to be released to plan participants. Note 3 provides more information related to earnings per share. Segment Reporting The Company has evaluated the activities relating to its strategic business units. The controlling interest in the FitzGibbons Agency is dissimilar in nature and management when compared to the Company’s other strategic business units which are judged to be similar in nature and management. The Company has determined that the FitzGibbons Agency is below the reporting threshold in size in accordance with Accounting Standards Codification 280. Accordingly, the Company has determined it has no reportable segments. Comprehensive Income (Loss) Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities are reported as a separate component of the equity section of the statement of condition, such items, along with net income, are components of comprehensive income. Accumulated other comprehensive loss represents the sum of these items, with the exception of net income, as of the balance sheet date and is represented in the table below. As of December 31, Accumulated Other Comprehensive Loss By Component: 2020 2019 Unrealized loss for pension and other postretirement obligations $ (2,832 ) $ (3,677 ) Tax effect 739 960 Net unrealized loss for pension and other postretirement obligations (2,093 ) (2,717 ) Unrealized gain (loss) on available-for-sale securities 1,133 (293 ) Tax effect (296 ) 77 Net unrealized gain (loss) on available-for-sale securities 837 (216 ) Unrealized holding losses on hedging activities arising during the period (1,308 ) - Tax effect 342 - Net unrealized loss on hedging activities (966 ) - Unrealized loss on securities transferred to held-to-maturity (22 ) (54 ) Tax effect 8 16 Net unrealized loss on securities transferred to held-to-maturity (14 ) (38 ) Accumulated other comprehensive loss $ (2,236 ) $ (2,971 ) Reclassifications Certain amounts in the 2019 consolidated financial statements have been reclassified to conform to the current year presentation. These reclassifications had no effect on net income as previously reported.

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
NEW ACCOUNTING PRONOUNCEMENTS	Note 2: New Accounting Pronouncements The Financial Accounting Standards Board (“FASB”) and, to a lesser extent, other authoritative rulemaking bodies promulgate GAAP to regulate the standards of accounting in the United States. From time to time, the FASB issues new GAAP standards, known as Accounting Standards Updates (“ASUs”) some of which, upon adoption, may have the potential to change the way in which the Company recognizes or reports within its consolidated financial statements. The following table provides a description of standards that were adopted in 2020 and standards not yet adopted as of December 31, 2020, but could have an impact on the Company's consolidated financial statements upon adoption. Standards Adopted in 2020 Standard Description Required Date of Implementation Effect on Consolidated Financial Statements Fair Value Measurement (ASU 2018-13: Fair Value Measurement [Topic 820]: Disclosure Framework Changes to the Disclosure Requirements for Fair Value Measurement The FASB is issuing the amendments in this ASU as part of the disclosure framework project. The disclosure framework project’s objective and primary focus are to improve the effectiveness of disclosures in the notes to financial statements by facilitating clear communication of the information required by GAAP that is most important to users of each entity’s financial statements. The amendments in this ASU modify the disclosure requirements for entities such as the Company on fair value measurements in Topic 820, Fair Value Measurement The following disclosure requirements were removed from Topic 820: 1. The amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy. 2. The policy for timing of transfers between levels. 3. The valuation processes for Level 3 fair value measurements. The following disclosure requirements were modified in Topic 820: 1. For investments in certain entities that calculate net asset value, an entity is required to disclose the timing of liquidation of an investee’s assets and the date when restrictions from redemption might lapse only if the investee has communicated the timing to the entity or announced the timing publicly. 2. The amendments clarify that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. The following disclosure requirements were added to Topic 820: 1. The changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period. 2. The range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information (such as the median or arithmetic average) in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements. January 1, 2020 The adoption of this ASU had no material impact to the Company's consolidated statements of condition or income. Standard Description Required Date of Implementation Effect on Consolidated Financial Statements Various Codification Improvements (ASU 2019-04: Codification Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments) The FASB is issuing the amendments in this ASU as part of its ongoing project on its agenda for improving the Codification and correcting its unintended application. The items addressed in that project generally are not expected to have a significant effect on current accounting practices. The amendments in this ASU are summarized below. For Codification Improvements specific to ASU 2016-01, the following topics are covered within ASU 2019-04: • Scope Clarifications • Held-to-Maturity Debt Securities Fair Value Disclosures • Applicability of Topic 820 to the Measurement Alternative • Remeasurement of Equity Securities at Historical Exchange Rates The ASU also covers a number of issues that relate to hedge accounting (ASU-2017-12) including: • Partial-Term Fair Value Hedges of Interest Rate Risk • Amortization of Fair Value Hedge Basis Adjustments • Disclosure of Fair Value Hedge Basis Adjustments • Consideration of the Hedged Contractually Specified Interest Rate under the Hypothetical Derivative Method • Scoping for Not-for-Profit Entities • Hedge Accounting Provisions Applicable to Certain Private Companies and Not-for- Profit Entities • Application of a First- Payments-Received Cash Flow Hedging Technique to Overall Cash Flows on a Group of Variable Interest Payments • Transition Guidance The amendments to Topic 326 and other Topics in this Update include items related to the amendments in Update 2016-13 discussed at the June 2018 and November 2018 Credit Losses Transition Resource Group (“TRG”) meetings. The amendments clarify or address stakeholders’ specific issues about certain aspects of the amendments in Update 2016-13 on a number of different topics, including the following: • Accrued Interest • Transfers between Classifications or Categories for Loans and Debt Securities • Recoveries • Consideration of Prepayments in Determining the Effective Interest Rate • Consideration of Estimated Costs to Sell When Foreclosure Is Probable • Vintage Disclosures— Line-of-Credit Arrangements Converted to Term Loans • Contractual Extensions and Renewals This ASU 2019-04 has various implementation dates dependent on a number of factors as it pertains to the above items. The Company has adopted ASU 2016-01 and ASU 2017-12, but has not adopted ASU 2016-13. The adoption of this ASU had no material impact to its consolidated statements of condition or income. Standards Not Yet Adopted as of December 31, 2020 Standard Description Required Date of Implementation Effect on Consolidated Financial Statements Measurement of Credit Losses on Financial Instruments (ASU 2016-13: Financial Instruments—Credit Losses [Topic 326]: Measurement of Credit Losses on Financial Instruments) The amended guidance replaces the current incurred loss model for determining the allowance for credit losses. The guidance requires financial assets measured at amortized cost to be presented at the net amount expected to be collected. The allowance for credit losses will represent a valuation account that is deducted from the amortized cost basis of the financial assets to present their net carrying value at the amount expected to be collected. The income statement will reflect the measurement of credit losses for newly recognized financial assets as well as expected increases or decreases of expected credit losses that have taken place during the period. When determining the allowance, expected credit losses over the contractual term of the financial asset(s) (taking into account prepayments) will be estimated considering relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The amended guidance also requires recording an allowance for credit losses for purchased financial assets with a more-than-insignificant amount of credit deterioration since origination. The initial allowance for these assets will be added to the purchase price at acquisition rather than being reported as an expense. Subsequent changes in the allowance will be recorded through the income statement as an expense adjustment. In addition, the amended guidance requires credit losses relating to available-for-sale debt securities to be recorded through an allowance for credit losses. The calculation of credit losses for available-for-sale securities will be similar to how it is determined under existing guidance. January 1, 2023 (early adoption permitted as of January 1, 2019) The Company is assessing the new guidance to determine what modifications to existing credit estimation processes may be required. The new guidance is complex and management is still evaluating the preliminary output from models that have been developed during this evaluative phase. In addition, future levels of allowances will also reflect new requirements to include estimated credit losses on investment securities classified as held-to-maturity, if any. The Company has formed an Implementation Committee, whose membership includes representatives of senior management, to develop plans that will encompass: (1) internal methodology changes (2) data collection and management activities, (3) internal communication requirements, and (4) estimation of the projected impact of this guidance. It has been generally assumed that the conversion from the incurred loss model, required under current GAAP, to the current expected credit loss (CECL) methodology (as required upon implementation of this Update) will, more likely than not, result in increases to the allowances for credit losses at many financial institutions. However, the amount of any change in the allowance for credit losses resulting from the new guidance will ultimately be impacted by the provisions of this guidance as well as by the loan and debt security portfolios composition and asset quality at the adoption date, and economic conditions and forecasts at the time of adoption. The amendments in this Update should be applied on a modified retrospective basis by means of a cumulative-effect adjustment to the opening retained earnings balance in the statement of financial position as of the date that an entity adopted the amendments in Update 2016-13. The cumulative impact of the economic effects of the COVID-19 pandemic on the changes to the allowance for loan losses, that will be required upon the implementation of the CECL methodology, cannot be estimated at this time. Standard Description Required Date of Implementation Effect on Consolidated Financial Statements Transition Relief for the Implementation of ASU-2016-13 (ASU 2019-5: Financial Instruments—Credit Losses [Topic 326]: Targeted Transition Relief) The amendments in this ASU provide entities that have certain instruments within the scope of Subtopic 326-20, Financial Instruments—Credit Losses—Measured at Amortized Cost Financial Instruments—Overall Fair Value Measurement—Overall See comments above related to ASU 2016-13. See comments above related to ASU 2016-13. Standard Description Required Date of Implementation Effect on Consolidated Financial Statements Compensation (ASU 2018-14: Compensation - Retirement Benefits - Defined Benefit Plans - General [Subtopic 715 – 20]: Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans) The FASB is issuing the amendments in this ASU as part of the disclosure framework project. The amendments in this ASU modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The following disclosure requirements are removed from Subtopic 715-20: 1. The amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year. 2. The amount and timing of plan assets expected to be returned to the employer. 3. Related party disclosures about the amount of future annual benefits covered by insurance and annuity contracts and significant transactions between the employer or related parties and the plan. 4. The effects of a one-percentage-point change in assumed health care cost trend rates on the (a) aggregate of the service and interest cost components of net periodic benefit costs and (b) benefit obligation for postretirement health care benefits. The following disclosure requirements are added to Subtopic 715-20: 1. The weighted-average interest crediting rates for cash balance plans and other plans with promised interest crediting rates. 2. An explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. The amendments in this ASU also clarify the disclosure requirements in paragraph 715-20-50-3, which state that the following information for defined benefit pension plans should be disclosed: 1. The projected benefit obligation (PBO) and fair value of plan assets for plans with PBOs in excess of plan assets. 2. The accumulated benefit obligation (ABO) and fair value of plan assets for plans with ABOs in excess of plan assets. The amendments in this ASU are effective for fiscal years ending after December 15, 2020, for public business entities and for fiscal years ending after December 15, 2021, for all other entities. Early adoption is permitted for all entities. The Company does not expect that the new guidance will have a material impact to the Company's consolidated statements of condition or income. Standard Description Required Date of Implementation Effect on Consolidated Financial Statements Investments (ASU 2020-01- Equity Securities [Topic 321], Investments—Equity Method and Joint Ventures [Topic 323], and Derivatives and Hedging [Topic 815]—Clarifying the Interactions between Topic 321, Topic 323, and Topic 815) The amendments in this Update clarify the interaction of the accounting for equity securities under Topic 321 and investments accounted for under the equity method of accounting in Topic 323 and the accounting for certain forward contracts and purchased options accounted for under Topic 815. The amendments clarify that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. The amendments clarify that for the purpose of applying paragraph 815-10-15-141(a) an entity should not consider whether, upon the settlement of the forward contract or exercise of the purchased option, individually or with existing investments, the underlying securities would be accounted for under the equity method in Topic 323 or the fair value option in accordance with the financial instruments guidance in Topic 825. An entity also would evaluate the remaining characteristics in paragraph 815-10-15-141 to determine the accounting for those forward contracts and purchased options. The amendments in this ASU are effective for fiscal years ending after December 15, 2020, for public business entities and for fiscal years ending after December 15, 2021, for all other entities. Early adoption is permitted for all entities. The amendments in this Update should be applied prospectively. The Company does not expect that the new guidance will have a material impact to its consolidated statements of condition or income. Standard Description Required Date of Implementation Effect on Consolidated Financial Statements Income Taxes (ASU 2019-12- Simplifying the Accounting for Income Taxes) The FASB Board is issuing this Update as part of its initiative to reduce complexity in accounting standards (the Simplification Initiative). The amendments in this Update simplify the accounting for income taxes by removing the following exceptions, among others not considered to be applicable to the Company: 1. Exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items (for example, discontinued operations or other comprehensive income) 2. Exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The amendments in this Update also simplify the accounting for income taxes by doing the following: 1. Requiring that an entity recognize a franchise tax (or similar tax) that is partially based on income as an income-based tax and account for any incremental amount incurred as a non-income-based tax. 2. Requiring that an entity evaluate when a step up in the tax basis of goodwill should be considered part of the business combination in which the book goodwill was originally recognized and when it should be considered a separate transaction. 3. Specifying that an entity is not required to allocate the consolidated amount of current and deferred tax expense to a legal entity that is not subject to tax in its separate financial statements. However, an entity may elect to do so (on an entity-by-entity basis) for a legal entity that is both not subject to tax and disregarded by the taxing authority. 4. Requiring that an entity reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. 5. Making minor Codification improvements for income taxes related to employee stock ownership plans and investments in qualified affordable housing projects accounted for using the equity method. The amendments in this ASU are effective for fiscal years ending after December 15, 2020, for public business entities and for fiscal years ending after December 15, 2021, for all other entities. Early adoption of the amendments is permitted, including adoption in any interim period for (1) public business entities for periods for which financial statements have not yet been issued and (2) all other entities for periods for which financial statements have not yet been made available for issuance. An entity that elects to early adopt the amendments in an interim period should reflect any adjustments as of the beginning of the annual period that includes that interim period. Additionally, an entity that elects early adoption must adopt all the amendments in the same period. The amendments in this Update related to separate financial statements of legal entities that are not subject to tax should be applied on a retrospective basis for all periods presented. The amendments related to changes in ownership of foreign equity method investments or foreign subsidiaries should be applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. The amendments related to franchise taxes that are partially based on income should be applied on either a retrospective basis for all periods presented or a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. All other amendments should be applied on a prospective basis. The Company does not expect the new guidance will have a material impact to its consolidated statements of condition or income. Standard Description Required Date of Implementation Effect on Consolidated Financial Statements Financial Instruments—Credit Losses (ASU 2019-11- Codification Improvements to Topic 326) On June 16, 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments—Credit Losses (Topic 326) Financial Instruments—Credit Losses The amendments in this Update clarify or address stakeholders' specific issues about certain aspects of the amendments in Update 2016-13 as described below: 1. Expected Recoveries for Purchased Financial Assets with Credit Deterioration (PCDs): The amendments clarify that the allowance for credit losses for PCD assets should include in the allowance for credit losses expected recoveries of amounts previously written off and expected to be written off by the entity and should not exceed the aggregate of amounts of the amortized cost basis previously written off and expected to be written off by an entity. In addition, the amendments clarify that when a method other than a discounted cash flow method is used to estimate expected credit losses, expected recoveries should not include any amounts that result in an acceleration of the noncredit discount. An entity may include increases in expected cash flows after acquisition. 2. Transition Relief for Troubled Debt Restructurings (TDRs): The amendments provide transition relief by permitting entities an accounting policy election to adjust the effective interest rate on existing TDRs using prepayment assumptions on the date of adoption of Topic 326 rather than the prepayment assumptions in effect immediately before the restructuring. 3. Disclosures Related to Accrued Interest Receivables: The amendments extend the disclosure relief for accrued interest receivable balances to additional relevant disclosures involving amortized cost basis. 4. Financial Assets Secured by Collateral Maintenance Provisions: The amendments clarify that an entity should assess whether it reasonably expects the borrower will be able to continually replenish collateral securing the financial asset to apply the practical expedient. The amendments clarify that an entity applying the practical expedient should estimate expected credit losses for any difference between the amount of the amortized cost basis that is greater than the fair value of the collateral securing the financial asset (that is, the unsecured portion of the amortized cost basis). An entity may determine that the expectation of nonpayment for the amount of the amortized cost basis equal to the fair value of the collateral securing the financial asset is zero. 5. Conforming Amendment to Subtopic 805-20: The amendment to Subtopic 805-20, Business Combinations—Identifiable Assets and Liabilities, and Any Noncontrolling Interest January 1, 2023 (early adoption permitted as of January 1, 2019). The effective dates and transition requirements for the amendments are the same as the effective dates and transition requirements in Update 2016-13. The Company is assessing the new guidance to determine what modifications to existing credit estimation processes may be required. The new guidance is complex and management is still evaluating the preliminary output from models that have been developed during this evaluative phase. In addition, future levels of allowances will also reflect new requirements to include estimated credit losses on investment securities classified as held-to-maturity, if any. The Company has formed an Implementation Committee, whose membership includes representatives of senior management, to develop plans that will encompass: (1) internal methodology changes (2) data collection and management activities, (3) internal communication requirements, and (4) estimation of the projected impact of this guidance. It has been generally assumed that the conversion from the incurred loss model, required under current GAAP, to the CECL methodology will, more likely than not, result in increases to the allowances for credit losses at many financial institutions. However, the amount of any change in the allowance for credit losses resulting from the new guidance will ultimately be impacted by the provisions of this guidance as well as by the loan and debt security portfolios composition and asset quality at the adoption date, and economic conditions and forecasts at the time of adoption. The amendments in this Update should be applied on a modified retrospective basis by means of a cumulative-effect adjustment to the opening retained earnings balance in the statement of financial position as of the date that an entity adopted the amendments in Update 2016-13. Standard Description Required Date of Implementation Effect on Consolidated Financial Statements Reference Rate Reform (ASU 2020-04- Facilitation of the Effects of Reference Rate Reform on Financial Reporting) The amendments provide optional expedients and exceptions for applying generally accepted accounting principles (GAAP) to contracts, hedging relationships, and other transactions affected by reference rate reform. The amendments apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The amendments (1) apply to contract modifications that replace a reference rate affected by reference rate reform, (2) provide exceptions to existing guidance related to changes to the critical terms of a hedging relationship due to reference rate reform (3) provide optional expedients for fair value hedging relationships, cash flow hedging relationships, and net investment hedging relationships, and (4) provide a onetime election to sell, transfer, or both sell and transfer debt securities classified as held to maturity that reference a rate affected by reference rate reform and that are classified as held to maturity before January 1, 2020. The amendments in this Update are effective for all entities as of March 12, 2020 through December 31, 2022. The amendments for contract modifications can be elected to be applied as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020. The amendments for existing hedging relationships can be elected to be applied as of the beginning of the interim period that includes March 12, 2020 and to new eligible hedging relationships entered into after the beginning of the interim period that includes March 12, 2020. The Company does not expect that the guidance will have a material effect on its consolidated statements of condition or income. Standard Description Required Date of Implementation Effect on Consolidated Financial Statements Debt (ASU 2020-06- Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging— Contracts in Entity's Own Equity (Subtopic 815-40) The amendments reduce the number of accounting models for convertible debt instruments and convertible preferred stock. The amendments also reduce form-over-substance-based guidance for the derivatives scope exception for contacts in an entity’s own equity. For convertible instruments, embedded conversion features no longer are separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives, or that do not result in substantial premiums accounted for as paid-in capital. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost and a convertible preferred stock will be accounted for as a single equity instrument measured at its historical cost, as long as no other features require bifurcation and recognition as derivatives. By removing those separation models, the interest rate of convertible debt instruments typically will be closer to the coupon interest rate on the instrument. The amendments also require certain changes to EPS calculations for convertible instruments as well as additional disclosures relating to conditions that cause conversion features to be met. For contracts in an entity’s own equity, the amendments revise the derivatives scope exception guidance as follows: 1. Remove the settlement in unregistered shares, collateral, and shareholder rights conditions from the settlement guidance. 2. Clarify that payment penalties for failure to timely file do not preclude equity classification. 3. Require instruments that are required to be classified as an asset or liability to be measured subsequently at fair value, with changes reported in earnings and disclosed in the financial statements. 4. Clarify that the scope of the disclosure requirements in the Contracts in an Entity’s Own Equity section of the Derivatives guidance applies only to freestanding instruments. 5. Clarify that the scope of the reassessment guidance in the Contracts in an Entity’s Own Equity section of the Derivatives guidance applies to both freestanding instruments and embedded features. The amendments in this update are effective for public business entities, excluding entities eligible to be smaller reporting companies as defined by the SEC, for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Board specified that an entity should adopt the guidance as of the beginning of its annual fiscal year. The amendments can be applied either on a modified retrospective method of transition or a fully retrospective method of transition. In applying the modified retrospective method, the guidance should be applied to transactions outstanding as of the beginning of the fiscal year in which the amendments are adopted. Transactions that were settled (or expired) during prior reporting periods are unaffected. The cumulative effect of the change should be recognized as an adjustment to the opening balance of retained earnings at the date of adoption. If applying the fully retrospective method of transition, the cumulative effect of the change should be recognized as an adjustment to the opening balance of retained earnings in the first comparative period presented. The fair value option is allowed to be irrevocably elected for any financial instrument that is a convertible security upon adoption of the amendments. The Company has not yet determined which transition method will be applied to the extent that such transition adjustments are applicable. The Company does not expect that the guidance will have a material effect on its consolidated statements of financial condition or income. Standard Description Required Date of Implementation Effect on Consolidated Financial Statements Codification Improvements to Subtopic 310-20, Receivables—Nonrefundable Fees and Other Costs (ASU 2020-08) The amendments affect the guidance in Accounting Standards Update No. 2017- 08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities For public business entities, the amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early application is not permitted. All entities should apply the amendments in this ASU on a prospective basis as of the beginning of the period of adoption for existing or newly purchased callable debt securities. The Company does not expect this guidance to have a material effect on its consolidated statements of condition or income. Standard Description Required Date of Implementation Effect on Consolidated Financial Statements Reference Rate Reform, Topic 848 (ASU 2021-01) The amendments in this ASU clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. Specifically, certain provisions in Topic 848, if elected by an entity, apply to derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. The amendments in this Update apply to all entities that elect to apply the optional guidance in Topic 848. The amendments in this ASU are effective immediately for all entities. An entity may elect to apply the amendments in this ASU on a full retrospective basis as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or on a prospective basis to new modifications from any date within an interim period that includes or is subsequent to the date of the issuance of a final ASU, up to the date that financial statements are available to be issued. If an entity elects to apply any of the amendments in this ASU for an eligible hedging relationship, any adjustments as a result of those elections must be reflected as of the date the entity applies the election. The amendments in this ASU do not apply to contract modifications made after December 31, 2022, new hedging relationships entered into after December 31, 2022, and existing hedging relationships evaluated for effectiveness in periods after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that apply certain optional expedients in which the accounting effects are recorded through the end of the hedging relationship (including periods after December 31, 2022). The Company does not expect that the guidance will have a material effect on its consolidated statement

Earnings Per Share [Abstract]
Earnings Per Share	NOTE 3: EARNINGS PER SHARE The Company entered into a securities purchase agreement with Castle Creek Capital Partners VII, L.P. on May 8, 2019, pursuant to which the Company sold: (i) shares of the Company’s common stock, par value $0.01 per share, at a purchase price of $14.25 per share; (ii) shares of a new series of preferred stock, Series B convertible perpetual preferred stock, par value $0.01 per share, at a purchase price of $14.25 per share; and (iii) a warrant, with an approximate fair value of $373,000, to purchase 125,000 shares of common stock at an exercise price equal to $14.25 per share, in a Private Placement transaction. As a result of the securities purchase agreement, the Company has common stock, preferred stock and a warrant that are all eligible to participate in dividends equal to the common stock dividends on a per share basis. Securities that participate in dividends, such as the Company’s preferred stock and warrant, are considered “participating securities.” The Company calculates net income available to common shareholders using the two-class method required for capital structures that include participating securities. In applying the two-class method, basic net income per share was calculated by dividing net income (less any dividends on participating securities) by the weighted average number of shares of common stock and participating securities outstanding for the period. Diluted earnings per share may include the additional effect of other securities, if dilutive, in which case the dilutive effect of such securities is calculated by applying either the two-class method or the Treasury Stock method to the assumed exercise or vesting of potentially dilutive common shares. The method yielding the more dilutive result is ultimately reported for the applicable period. Potentially dilutive common stock equivalents primarily consist of employee stock options and restricted stock units. Unallocated common shares held by the ESOP are not included in the weighted average number of common shares outstanding for purposes of calculating earnings per common share until they are committed to be released to plan participants. Anti-dilutive shares are common stock equivalents with average exercise prices in excess of the weighted average market price for the period presented. Anti-dilutive stock options, not included in the computation below, were 175,996 and -0- for the years ended 2020 and 2019, respectively.

The Company assesses whether OTTI is present when the fair value of a debt security is less than its amortized cost basis at the statement of condition date. Under these circumstances, OTTI is considered to have occurred (1) if we intend to sell the security; (2) if it is “more likely than not” we will be required to sell the security before recovery of its amortized cost basis; or (3) the present value of expected cash flows is not anticipated to be sufficient to recover the entire amortized cost basis. The guidance requires that credit-related OTTI is recognized in earnings while non-credit-related OTTI on securities not expected to be sold is recognized in other comprehensive income (“OCI”). Non-credit-related OTTI is based on other factors, including illiquidity and changes in the general interest rate environment. Presentation of OTTI is made in the consolidated statement of income on a gross basis, including both the portion recognized in earnings as well as the portion recorded in OCI. The gross OTTI would then be offset by the amount of non-credit-related OTTI, showing the net as the impact on earnings. Management does not believe any individual unrealized loss in investment securities within the portfolio as of December 31, 2020 represents OTTI. There were a total of eight securities classified as available-for-sale (aggregate amortized historical cost of $13.8 million, unrealized aggregate loss of $474,000, or -3.4%) and four securities classified as held-to-maturity (aggregate amortized historical cost of $5.6 million, unrealized aggregate loss of $146,000, or -2.6%) that were in an unrealized loss position for 12 months or longer at December 31, 2020. Each security which has been in an unrealized loss position for 12 months or more has been analyzed and is not considered to be impaired. These securities have unrealized losses primarily due to expected accelerated prepayments and/or residual fixed income securities market dislocations stemming from the pandemic. In substantially all cases, price improvement in future months is expected as the issuances approach maturity. The significant declines in general interest rates during 2020, has supported substantial price improvement across the entirety of the investment portfolio since March of 2020 and this trend continued through year end 2020. This trend favorably affected market values of the majority of the securities listed below. Of the total of 12 securities in an unrealized loss position for 12 months or more at December 31, 2020, three securities, representing 57.2% of the unamortized cost of the total securities in an unrealized loss position for 12 months or more, are issued by United States agencies or GSE’s and consist of mortgage-backed securities, collateralized mortgage obligations and direct agency financings. These positions in US government agency and GSE’s are deemed to have no credit impairment, thus, the disclosed unrealized losses relate primarily to changes in prepayment assumptions related to significantly lower general interest rates resulting from the economic effects of the pandemic. In addition to these three securities, the Company held the following nine non-government-issued/backed securities that were in an unrealized loss position for 12 or more months at December 31, 2020: • One privately-issued asset-backed security, collateralized by small business loans and categorized as available-for-sale, with an amortized historical cost of $82,000 and an aggregate market value of $80,000 (unrealized loss of $2,000 or -2.2%). This security maintains a credit rating established by one or more NRSRO above the minimum level required to be considered as investment grade and therefore, no credit-related OTTI is deemed to be present. • Four privately-issued collateralized mortgage obligation securities, collateralized by residential and commercial mortgage loans and categorized as available-for-sale, with an aggregate amortized historical cost of $2.6 million and an aggregate market value of $2.6 million (unrealized aggregate loss of $32,000 or -1.2%). These securities were not rated at the time of their issuances by any NRSRO but each security remains significantly collateralized through subordination and other credit enhancements. Therefore, no credit-related OTTI is deemed to be present. • One privately-issued asset-backed security, categorized as held-to-maturity and collateralized by small business loans, with an aggregate amortized historical cost of $955,000 and a market value of $938,000 (unrealized loss of $17,000 or -1.8%). This security was not rated at the time of its issuance by any NRSRO but remains significantly collateralized through subordination. Therefore, no credit-related OTTI is deemed to be present. • One privately-issued asset-backed security, categorized as held-to-maturity and collateralized by private-issue student loans, with an aggregate amortized historical cost of $1.9 million and an aggregate market value of $1.8 million (unrealized loss of $122,000 or -6.3%). This security was unrated at issuance but remains sufficiently collateralized through subordination. Therefore, no credit-related OTTI is deemed to be present. • One privately-issued asset-backed security, categorized as held-to-maturity and collateralized by federally-insured student loans, with an aggregate amortized historical cost of $1.9 million and an aggregate market value of $1.9 million (unrealized loss of $1,000 or -0.1%). This security maintains a credit rating established by one or more NRSRO above the minimum level required to be considered as investment grade and therefore, no credit-related OTTI is deemed to be present. • One privately-issued collateralized mortgage obligation security, collateralized by residential mortgage loans and categorized as held-to-maturity, with an aggregate amortized historical cost of $786,000 and a market value of $780,000 (unrealized loss of $6,000 or -0.8%). This security maintains a credit rating established by one or more NRSRO above the minimum level required to be considered as investment grade and therefore, no credit-related OTTI is deemed to be present. All other securities with market values less than their amortized historical costs for twelve or more months are issued by United States agencies or government sponsored enterprises and consist of mortgage-backed securities, collateralized mortgage obligations and direct agency financings. These positions in US government agency and government-sponsored enterprises are deemed to have no credit impairment, thus, the disclosed unrealized losses relate directly to changes in interest rates subsequent to the acquisition of the individual securities. The Company does not intend to sell these securities, nor is it more likely than not that the Company will be required to sell these securities prior to the recovery of the amortized cost. Proceeds of $29.3 million and $103.0 million, respectively on sales and redemptions of securities for the years ended December 31 resulted in gross realized gains (losses) detailed below (In thousands) 2020 2019 Realized gains on investments $ 1,107 $ 707 Realized losses on investments (31 ) (378 ) $ 1,076 $ 329 As of December 31, 2020 and December 31, 2019, securities with a fair value of $96.4 million and $92.4 million, respectively, were pledged to collateralize certain municipal deposit relationships. As of the same dates, securities with a fair value of $13.2 million and $21.3 million were pledged against certain borrowing arrangements. Management has reviewed its loan and mortgage-backed securities portfolios and determined that, to the best of its knowledge, little or no exposure exists to sub-prime or other high-risk residential mortgages. The Company is not in the practice of investing in, or originating, these types of investments or loans.

LOANS	NOTE 5: LOANS Major classifications of loans are as follows: December 31, December 31, (In thousands) 2020 2019 Residential mortgage loans: 1-4 family first-lien residential mortgages $ 227,185 $ 209,559 Construction 6,681 3,963 Loans held-for-sale (1) 1,526 35,790 Total residential mortgage loans 235,392 249,312 Commercial loans: Real estate 286,271 254,257 Lines of credit 49,103 58,617 Other commercial and industrial 78,629 82,092 Paycheck Protection Program loans 60,643 - Tax exempt loans 7,166 8,067 Total commercial loans 481,812 403,033 Consumer loans: Home equity and junior liens 38,624 46,389 Other consumer 70,905 82,607 Total consumer loans 109,529 128,996 Total loans 826,733 781,341 Net deferred loan (fees) costs (1,238 ) 110 Less allowance for loan losses (12,777 ) (8,669 ) Loans receivable, net $ 812,718 $ 772,782 (1) Based on ASC 948, Mortgage Banking, loans shall be classified as held-for-sale once a decision has been made to sell the loans and shall be transferred to the held-for-sale category at lower of cost or fair value. At December 31, 2020, the loans under contract to be sold had a principal balance of $1.5 million. These loans were transferred at their amortized cost of $1.5 million as of December 31, 2020, as the fair value of these loans was greater than the amortized cost. At December 31, 2019, the loans under contract to be sold had a principal balance of $35.8 million. These loans were transferred at their amortized cost of $35.9 million as of December 31, 2019, as the fair value of these loans was greater than the amortized cost. Although the Bank may sometimes purchase or fund loan participation interests outside of its primary market areas, the Bank generally originates residential mortgage, commercial, and consumer loans largely to customers throughout Oswego and Onondaga counties. Although the Bank has a diversified loan portfolio, a substantial portion of its borrowers’ abilities to honor their loan contracts is dependent upon the counties’ employment and economic conditions. As part of the Company’s overall balance sheet management strategies and the management’s ongoing efforts to profitably deploy its increased capital position following the equity sales transactions completed in May 2019, the Bank acquired eleven diverse pools of loans, originated by unrelated third parties, in six separate transactions during 2019 and two separate transactions during 2020. The purchase of participations in loans that are originated by third parties only occurs after the completion of thorough pre-acquisition due diligence. Loans in which the Company acquires a participating interest are determined to meet, in all material respects, the Company’s internal underwriting policies, including credit and collateral suitability thresholds, prior to acquisition. In addition, the financial condition of the originating entity, which are generally retained as the ongoing loan servicing provider for participations acquired by the Bank, are analyzed prior to the acquisition of the participating interests and monitored on a regular basis thereafter for the life of those interests.

Management and the board of directors reviews and approves these policies and procedures on a regular basis. A reporting system supplements the review process by frequently providing management with reports related to loan production, loan quality, loan delinquencies, nonperforming and potential problem loans. Diversification in the loan portfolio is also a means of managing risk associated with fluctuations in economic conditions. Homogenous pools of purchased loans are subject to substantial prepurchase analyses led by a team of the Bank’s senior executives and credit analysts. In each case, the Bank’s analytical processes consider the types of loans being evaluated, the underwriting criteria employed by the originating entity, the historical performance of such loans, especially in the most recent deeply recessionary environments, the collateral enhancements and other credit loss mitigation factors offered by the seller and the capabilities and financial stability of the servicing entities involved. From a credit risk perspective, these loan pools also benefit from broad diversification, including wide geographic dispersion, the readily-verifiable historical performance of similar loans issued by the originators, as well as the overall experience and skill of the underwriters and servicing entities involved as counterparties to the Bank in these transactions. The performance of all purchased loan pools are monitored regularly from detailed reports and remittance reconciliations provided at least monthly by the servicing entities. Risk Characteristics of Portfolio Segments Each portfolio segment generally carries its own unique risk characteristics. The residential mortgage loan segment is impacted by general economic conditions, unemployment rates in the Bank’s service area, real estate values and the forward expectation of improvement or deterioration in economic conditions. First and second lien residential mortgages, acquired via purchase are impacted by general economic conditions, unemployment rates in the general areas in which the loan collateral is located, real estate values in those areas and the forward expectation of improvement or deterioration in economic conditions. The commercial loan segment is impacted by general economic conditions but, more specifically, the industry segment in which each borrower participates. Unique competitive changes within a borrower’s specific industry, or geographic location could cause significant changes in the borrower’s revenue stream, and therefore, impact its ability to repay its obligations. Commercial real estate is also subject to general economic conditions but changes within this segment typically lag changes seen within the consumer and commercial segment. Included within this portfolio are both owner occupied real estate, in which the borrower occupies the majority of the real estate property and upon which the majority of the sources of repayment of the obligation is dependent upon, and non-owner occupied real estate, in which several tenants comprise the repayment source for this portfolio segment. The composition and competitive position of the tenant structure may cause adverse changes in the repayment of debt obligations for the non-owner occupied class within this segment. The consumer loan segment is impacted by general economic conditions, unemployment rates in the geographic areas in which borrowers and loan collateral are located, and the forward expectation of improvement or deterioration in economic conditions. Real estate loans, including residential mortgages, commercial real estate loans and home equity, comprise 68% of the portfolio in 2020, similar to the composition in 2019, where such loans represented 70% of total loans. Loans secured by real estate generally provide strong collateral protection and thus significantly reduce the inherent credit risk in the portfolio. Management has reviewed its loan portfolio and determined that, to the best of its knowledge, little or no exposure exists to sub-prime or other high-risk residential mortgages. The Company is not in the practice of originating these types of loans. Description of Credit Quality Indicators The Company utilizes an eight tier risk rating system to evaluate the quality of its loan portfolio. Loans that are risk rated “1” through “4” are considered “Pass” loans. In accordance with regulatory guidelines, loans rated “5” through “8” are termed “criticized” loans and loans rated “6” through “8” are termed “classified” loans. A description of the Company’s credit quality indicators follows. For Commercial Loans: 1. Prime 2. Strong 3. Satisfactory 4. Satisfactory Watch: 5. Special Mention 6. Substandard 7. Doubtful 8. Loss For Residential Mortgage and Consumer Loans: Residential mortgage and consumer loans are assigned a “Pass” rating unless the loan has demonstrated signs of weakness as indicated by the ratings below. 5. Special Mention 6. Substandard 7. Doubtful The risk ratings for classified loans are evaluated at least quarterly for commercial loans or when credit deficiencies arise, such as delinquent loan payments, for commercial, residential mortgage or consumer loans. See further discussion of risk ratings in Note 1. The following table presents the segments and classes of the loan portfolio summarized by the aggregate pass rating and the criticized and classified ratings of special mention, substandard and doubtful within the Company's internal risk rating system: As of December 31, 2020 Special (In thousands) Pass Mention Substandard Doubtful Total Residential mortgage loans: 1-4 family first-lien residential mortgages $ 222,386 $ 1,151 $ 3,196 $ 452 $ 227,185 Construction 6,681 - - - 6,681 Loans held-for-sale 1,526 - - - 1,526 Total residential mortgage loans 230,593 1,151 3,196 452 235,392 Commercial loans: Real estate 267,736 9,541 8,615 379 286,271 Lines of credit 40,733 5,132 3,154 84 49,103 Other commercial and industrial 65,441 4,770 8,153 265 78,629 Paycheck Protection Program loans 60,643 - - - 60,643 Tax exempt loans 7,166 - - - 7,166 Total commercial loans 441,719 19,443 19,922 728 481,812 Consumer loans: Home equity and junior liens 37,926 54 411 233 38,624 Other consumer 70,502 104 218 81 70,905 Total consumer loans 108,428 158 629 314 109,529 Total loans $ 780,740 $ 20,752 $ 23,747 $ 1,494 $ 826,733 As of December 31, 2019 Special (In thousands) Pass Mention Substandard Doubtful Total Residential mortgage loans: 1-4 family first-lien residential mortgages $ 205,554 $ 1,093 $ 1,731 $ 1,181 $ 209,559 Construction 3,963 - - - 3,963 Loans held-for-sale 35,790 - - - 35,790 Total residential mortgage loans 245,307 1,093 1,731 1,181 249,312 Commercial loans: Real estate 238,288 12,473 3,194 302 254,257 Lines of credit 50,396 7,945 276 - 58,617 Other commercial and industrial 72,653 8,473 923 43 82,092 Tax exempt loans 8,067 - - - 8,067 Total commercial loans 369,404 28,891 4,393 345 403,033 Consumer loans: Home equity and junior liens 45,414 191 477 307 46,389 Other consumer 82,252 167 188 - 82,607 Total consumer loans 127,666 358 665 307 128,996 Total loans $ 742,377 $ 30,342 $ 6,789 $ 1,833 $ 781,341 Nonaccrual and Past Due Loans Loans are placed on nonaccrual when the contractual payment of principal and interest has become 90 days past due or management has serious doubts about further collectability of principal or interest, even though the loan may be performing. Loans are considered past due if the required principal and interest payments have not been received within thirty days of the payment due date.

The Company is required to disclose certain activities related to Troubled Debt Restructurings (“TDR”) in accordance with accounting guidance. Certain loans have been modified in a TDR where economic concessions have been granted to a borrower who is experiencing, or expected to experience, financial difficulties. These economic concessions could include a reduction in the loan interest rate, extension of payment terms, reduction of principal amortization, or other actions that it would not otherwise consider for a new loan with similar risk characteristics. The Company is required to disclose new TDRs for each reporting period for which an income statement is being presented. Pre-modification outstanding recorded investment is the principal loan balance less the provision for loan losses before the loan was modified as a TDR. Post-modification outstanding recorded investment is the principal balance less the provision for loan losses after the loan was modified as a TDR. Additional provision for loan losses is the change in the allowance for loan losses between the pre-modification outstanding recorded investment and post-modification outstanding recorded investment. The table below details loans that had been modified as TDRs for the year ended December 31, 2020. For the year ended December 31, 2020 (In thousands) Number of loans Pre-modification outstanding recorded investment Post-modification outstanding recorded investment Additional provision for loan losses Commercial real estate loans 1 $ 1,234 $ 1,234 $ - Commercial and industrial loans 2 397 427 129 The TDR's evaluated for impairment for the year ended December 31, 2020 have been classified as TDRs due to economic concessions granted, which include reductions in the stated interest rates or an extended maturity date that will result in a delay in payment from the original contractual maturity. The table below details loans that have been modified as TDRs for the year ended December 31, 2019. For the year ended December 31, 2019 (In thousands) Number of loans Pre-modification outstanding recorded investment Post-modification outstanding recorded investment Additional provision for loan losses Residential real estate loans 1 $ 205 $ 250 $ - The TDR evaluated for impairment for the year ended December 31, 2019 has been classified as a TDR due to economic concessions granted, which consisted of additional funds advanced without associated increases in collateral and an extended maturity date that will result in a delay in payment from the original contractual maturity. The Company is required to disclose loans that have been modified as TDRs within the previous 12 months in which there was payment default after the restructuring. The Company defines payment default as any loans 90 days past due on contractual payments. The Company had no loans that had been modified as TDRs during the twelve months prior to December 31, 2020, which had subsequently defaulted during the year ended December 31, 2020. The Company had no loans that had been modified as TDRs during the twelve months prior to December 31, 2019, which had subsequently defaulted during the year ended December 31, 2019. When the Company modifies a loan within a portfolio segment that is individually evaluated for impairment, a potential impairment is analyzed either based on the present value of the expected future cash flows discounted at the interest rate of the original loan terms or the fair value of the collateral less costs to sell. If it is determined that the value of the loan is less than its recorded investment, then impairment is recognized as a component of the provision for loan losses, an associated increase to the allowance for loan losses or as a charge-off to the allowance for loan losses in the current period.

Allowance For Loan Losses [Abstract]

Based on ASC 948, Mortgage Banking, loans shall be classified as held-for-sale once a decision has been made to sell the loans and shall be transferred to the held-for-sale category at lower of cost or fair value. The Company’s methodology for determining its allowance for loan losses includes an analysis of qualitative factors that are added to the historical loss rates in arriving at the total allowance for loan losses needed for this general pool of loans. The qualitative factors include: • Changes in national and local economic trends; • The rate of growth in the portfolio; • Trends of delinquencies and nonaccrual balances; • Changes in loan policy; and • Changes in lending management experience and related staffing. Each factor is assigned a value to reflect improving, stable or declining conditions based on management’s best judgment using relevant information available at the time of the evaluation. These qualitative factors, applied to each product class, make the evaluation inherently subjective, as it requires material estimates that may be susceptible to significant revision as more information becomes available. Adjustments to the factors are supported through documentation of changes in conditions in a narrative accompanying the allowance for loan losses analysis and calculation. As a result of the COVID-19 pandemic, the Company’s management extensively reviewed a broad array of econometric projections and the potential effect of changes in those projections on anticipated loan performance. As a result, certain qualitative factors were substantially modified during 2020 in order to determine the adequacy of the allowance for loan losses during the year and at December 31, 2020. The allocation of the allowance for loan losses summarized on the basis of the Company’s calculation methodology was as follows: December 31, 2020 1-4 family first-lien Other residential Commercial Commercial commercial (In thousands) mortgage Construction real estate lines of credit and industrial Specifically reserved $ 205 $ - $ 231 $ 925 $ 1,278 Historical loss rate 88 - 80 92 56 Qualitative factors 638 - 4,465 653 1,658 Total $ 931 $ - $ 4,776 $ 1,670 $ 2,992 Home equity Other Tax exempt and junior liens consumer Unallocated Total Specifically reserved $ - $ 142 $ - $ - $ 2,781 Historical loss rate - 325 863 - 1,504 Qualitative factors 1 272 260 - 7,947 Other - - - 545 545 Total $ 1 $ 739 $ 1,123 $ 545 $ 12,777 December 31, 2019 1-4 family first-lien Other residential Commercial Commercial commercial (In thousands) mortgage Construction real estate lines of credit and industrial Specifically reserved $ 97 $ - $ 78 $ 98 $ 406 Historical loss rate 43 - 98 106 34 Qualitative factors 440 - 3,834 991 1,205 Total $ 580 $ - $ 4,010 $ 1,195 $ 1,645 Home equity Other Tax exempt and junior liens consumer Unallocated Total Specifically reserved $ - $ 150 $ 1 $ - $ 830 Historical loss rate - 85 167 - 533 Qualitative factors 1 318 245 - 7,034 Other - - - 272 272 Total $ 1 $ 553 $ 413 $ 272 $ 8,669

Subordinated Borrowings [Abstract]
SUBORDINATED LOANS	NOTE 13: SUBORDINATED LOANS The Company has a non-consolidated subsidiary trust, Pathfinder Statutory Trust II, of which the Company owns 100% of the common equity. The Trust issued $5,000,000 of 30-year floating rate Company-obligated pooled capital securities of Pathfinder Statutory Trust II (“Floating-Rate Debentures”). The Company borrowed the proceeds of the capital securities from its subsidiary by issuing floating rate junior subordinated deferrable interest debentures having substantially similar terms. The capital securities mature in 2037 and are treated as Tier 1 capital by the FDIC and FRB. The capital securities of the trust are a pooled trust preferred fund of Preferred Term Securities VI, Ltd., whose interest rate resets quarterly, and are indexed to the 3-month LIBOR rate plus 1.65%. These securities have a The Company paid $124,000 and $213,000 in interest expense related to this issuance in 2020 and 2019, respectively. The Company's equity interest in the trust subsidiary is included in other assets on the Consolidated Statements of Financial Condition at December 31, 2020 and 2019. For regulatory reporting purposes, the Federal Reserve has indicated that the preferred securities will continue to qualify as Tier 1 Capital subject to previously specified limitations, until further notice. If regulators make a determination that Trust Preferred Securities can no longer be considered in regulatory capital, the securities become callable and the Company may redeem them. On October 15, 2015, the Company executed a $10.0 million non-amortizing Subordinated Loan (the 2015 Subordinated Loan) with an unrelated third party that is scheduled to mature on October 1, 2025. The Company has the right to prepay the 2015 Subordinated Loan on the first day of any calendar quarter after October 15, 2020 without penalty. The annual interest rate charged to the Company will be 6.25% through the maturity date of the 2015 Subordinated Loan. The 2015 Subordinated Loan is senior in the Company’s credit repayment hierarchy only to the Company’s common equity and preferred stock and, as a result, qualifies as Tier 2 capital for all future periods when applicable. The Company paid $172,000 in origination and legal fees as part of this transaction. These fees were amortized over the life of the 2015 Subordinated Loan through its first call date using the effective interest method. The effective cost of funds related to this transaction was 6.44% calculated under this method through October 15, 2020 and is and will be 6.25% thereafter until the stated maturity date. Interest expense, related to this borrowing, of $650,000 and $650,000 was recorded in the years ended December 31, 2020 and 2019, respectively. On October 14, 2020, the Company executed a private placement of $25.0 million of its 5.50% Fixed to Floating Rate non-amortizing Subordinated Loan (the “2020 Subordinated Loan”) to certain qualified institutional buyers and accredited institutional investors.

Compensation And Retirement Disclosure [Abstract]
EMPLOYEE BENEFITS AND DEFERRED COMPENSATION AND SUPPLEMENTAL RETIREMENT PLANS	NOTE 14: Employee Benefits and Deferred Compensation and Supplemental Retirement Plans The Company has a noncontributory defined benefit pension plan covering substantially all employees. The plan provides defined benefits based on years of service and final average salary. On May 14, 2012, the Company informed its employees of its decision to freeze participation and benefit accruals under the plan, primarily to reduce some of the volatility in earnings that can accompany the maintenance of a defined benefit plan. The plan was frozen on June 30, 2012. Compensation earned by employees up to June 30, 2012 is used for purposes of calculating benefits under the plan but there will be no future benefit accruals after this date. Participants as of June 30, 2012 will continue to earn vesting credit with respect to their frozen accrued benefits as they continue to work. In addition, the Company provides certain health and life insurance benefits for a limited number of eligible retired employees. The healthcare plan is contributory with participants’ contributions adjusted annually; the life insurance plan is noncontributory. Employees with less than 14 years of service as of January 1, 1995, are not eligible for the health and life insurance retirement benefits. The following tables set forth the changes in the plans’ benefit obligations, fair value of plan assets and the plans’ funded status as of December 31: Pension Benefits Postretirement Benefits (In thousands) 2020 2019 2020 2019 Change in benefit obligations: Benefit obligations at beginning of year $ 11,892 $ 10,095 $ 414 $ 454 Service cost - - - - Interest cost 466 494 16 22 Plan participants' contribution - - 9 8 Actuarial loss (gain) 873 1,558 (25 ) (27 ) Benefits paid (264 ) (255 ) (45 ) (43 ) Benefit obligations at end of year 12,967 11,892 369 414 Change in plan assets: Fair value of plan assets at beginning of year 16,985 14,522 - - Actual return on plan assets 2,553 2,718 - - Benefits paid (264 ) (255 ) (45 ) (43 ) Plan participants' contribution - - 9 8 Employer contributions - - 36 35 Fair value of plan assets at end of year 19,274 16,985 - - Funded (unfunded) status - asset (liability) $ 6,307 $ 5,093 $ (369 ) $ (414 ) The funded status of the pension was recorded within other assets on the statement of condition. The unfunded status of the postretirement plan is recorded within other liabilities on the statement of condition. Amounts recognized in accumulated other comprehensive loss as of December 31 are as follows: Pension Benefits Postretirement Benefits (In thousands) 2020 2019 2020 2019 Net loss $ 2,743 $ 3,557 $ 87 $ 117 Tax Effect 716 929 23 31 $ 2,027 $ 2,628 $ 64 $ 86 Gains and losses in excess of 10% of the greater of the benefit obligation or the fair value of assets are amortized over the average remaining service period of active participants. The Company utilized the actual projected cash flows of the participants in both plans for the years ended December 31, 2020 and December 31, 2019. The following points address the approach taken. 1. An analysis of the defined benefit pension plan’s expected future cash flows and high-quality fixed income investments currently available and expected to be available during the period to maturity of the pension benefits yielded a single discount rate of 3.45% at December 31, 2020. 2. An analysis of the postretirement health plan’s expected future cash flows and high-quality fixed-income investments currently available and expected to be available during the period to maturity of the retiree medical benefits yielded a single discount rate of 3.45% at December 31, 2020. 3. Each discount rate was developed by matching the expected future cash flows of the Bank to high quality bonds. Every bond considered has earned ratings of at least AA by Fitch Group, AA by Standard & Poor’s, or Aa2 by Moody’s Investor Services. The accumulated benefit obligation for the defined benefit pension plan was $13.0 million and $11.9 million at December 31, 2020 and 2019, respectively. The postretirement plan had an accumulated benefit obligation of $369,000 and $414,000 at December 31, 2020 and 2019, respectively. The significant assumptions used in determining the benefit obligations as of December 31, are as follows: Pension Benefits Postretirement Benefits 2020 2019 2020 2019 Weighted average discount rate 3.45 % 3.97 % 3.45 % 3.97 % Rate of increase in future compensation levels - - - - Assumed health care cost trend rates have a significant effect on the amounts reported for the postretirement health care plan. The annual rates of increase in the per capita cost of covered medical and prescription drug benefits for future years were assumed to be 4.50% for 2021, gradually decreasing to 4.20% in 2024 and remain at that level thereafter. The composition of the net periodic benefit plan (benefit) cost for the years ended December 31 is as follows: Pension Benefits Postretirement Benefits (In thousands) 2020 2019 2020 2019 Service cost $ - $ - $ - $ - Interest cost 466 494 16 22 Expected return on plan assets (1,094 ) (934 ) - - Amortization of transition obligation - - - - Amortization of net losses 228 328 10 12 Amortization of unrecognized past service liability - - (5 ) (5 ) Net periodic benefit plan (benefit) cost $ (400 ) $ (112 ) $ 21 $ 29 The significant assumptions used in determining the net periodic benefit plan cost for years ended December 31, were as follows: Pension Benefits Postretirement Benefits 2020 2019 2020 2019 Weighted average discount rate 3.45 % 3.97 % 3.45 % 3.97 % Expected long term rate of return on plan assets 6.00 % 6.50 % - - Rate of increase in future compensation levels - - - - The long term rate of return on assets assumption was set based on historical returns earned by equities and fixed income securities, adjusted to reflect expectations of future returns as applied to the plan’s target allocation of asset classes. Equities and fixed income securities were assumed to earn real rates of return in the ranges of 6.0%-8.0% and 3.0%-5.0%, respectively. The long-term inflation rate was estimated to be 2.5%. When these overall return expectations are applied to the plan’s target allocation, the expected rate of return was determined to be in the range of 5.0% to 7.0%. Management chose to use a 6.0% expected long-term rate of return in 2020 and a 6.0% expected long-term rate of return in 2021 reflecting current economic conditions and expected rates of return. Based on the $19.3 million fair value of plan assets at December 31, 2020, each 50 basis point decrease in the expected long-term rate of return would reduce after tax net income at 2021 expected marginal tax rate of 26.1% by approximately $71,000. The estimated net actuarial loss that will be amortized from accumulated other comprehensive loss into net periodic benefit plan income during 2021 is $101,000. The estimated amortization of the unrecognized transition obligation and actuarial loss for the postretirement health plan in 2021 is $9,000. The expected net periodic benefit plan benefit for 2021 is estimated to be $588,000 for both retirement plans in aggregate. Plan assets are invested in three diversified investment portfolios of the Pentegra Retirement Trust (the “Trust”, formerly known as RSI Retirement Trust), a private placement investment fund. The Trust has been given discretion by the Plan Sponsor to determine the appropriate strategic asset allocation versus plan liabilities, as governed by the Trust’s Investment Policy Statement. The Plan is structured to utilize a Total Return approach which seeks to fund the current and future liabilities of the Plan via long-term growth in assets. The Plan’s asset allocation targets to hold 48% of assets in equity securities via investment in the Long-Term Growth – Equity Portfolio (‘LTGE’), 16% in intermediate-term investment grade bonds via investment in the Long-Term Growth – Fixed-Income Portfolio (‘LTGFI’), 35% in long duration bonds via the Liability Focused Fixed-Income Portfolio (‘LFFI’), and 1% in a cash equivalents portfolio (for liquidity). LTGE is a diversified portfolio that invests in a number of actively and passively managed equity-focused mutual funds and collective investment trusts. The Portfolio holds a diversified mix of equity funds in order to gain exposure to the U.S. and non-U.S. equity markets. LTGFI is a diversified portfolio that invests in a number of fixed-income mutual funds and collective investment trusts. The Portfolio invests primarily in intermediate-term bond funds with a focus on Core Plus fixed-income investment approaches. LFFI is a diversified high quality fixed-income portfolio that currently invests in passively managed collective investment trusts that hold long duration bonds. The investment objectives, investment strategies and risks of each of the daily valued and unitized Portfolios and the funds held within the Portfolios are detailed in the Private Placement Memorandum and the Trust’s Investment Policy Statement. The overall long-term investment objectives are to maintain plan assets at a level that will sufficiently cover long-term obligations and to generate a return on plan assets that will meet or exceed the rate at which long-term obligations will grow. The LTGE and LTGFI Portfolios are designed to provide long-term growth of equity and fixed-income assets with the objective of achieving an investment return in excess of the cost of funding the active life, deferred vested, and all 30-year term and longer obligations of retired lives in the Trust. The LFFI Portfolio is designed to fund the Trust’s estimated retired lives class of liabilities for 30 years. The ALT Strategy is designed to add diversification via the addition of relatively low correlation assets. Risk/volatility is further managed by the distinct investment objectives of each of the Trust’s Portfolios.

The SERP is intended to provide a benefit from the Bank upon retirement, death, disability or voluntary or involuntary termination of service (other than “for cause”), subject to the requirements of Section 409A of the Internal Revenue Code. Accordingly, the SERP obligates the Bank to make a contribution to each executive’s account on the last business day of each calendar year. In addition, the Bank, may, but is not required to, make additional discretionary contributions to the executive’s accounts from time to time. All executives currently participating in the plan, including the Named Executive Officers, are fully vested in the Bank’s contribution to the plan. In the event the executive is terminated involuntarily or resigns for good reason within 24 months following a change in control, the Bank is required to make additional annual contributions the lesser of: (1) three years or (2) the number of years remaining until the executive’s benefit age, subject to potential reduction to avoid an excess parachute payment under Code Section 280G. In the event of the executive’s death, disability or termination within 24 months after a change in control, the executive’s account will be paid in a lump sum to the executive or his beneficiary, as applicable. In the event the executive is entitled to a benefit from the SERP due to retirement or other termination of employment, the benefit will be paid either in a lump sum or in 10 annual installments as detailed in his or her participant agreement. At December 31, 2020 and 2019, other liabilities included $928,000 and $836,000, respectively, accrued under this plan.

Employee Stock Ownership Plan [Abstract]
EMPLOYEE STOCK OWNERSHIP PLAN	NOTE 16: EMPLOYEE STOCK OWNERSHIP PLAN The Bank established the Pathfinder Bank Employee Stock Ownership Plan (“Plan”) to purchase stock of the Company for the benefit of its employees. In July 2011, the Plan received a $1.1 million loan from Community Bank, N.A., guaranteed by the Company, to fund the Plan’s purchase of 125,000 shares of the Company’s treasury stock. The loan was being repaid in equal quarterly installments of principal plus interest over ten years beginning October 1, 2011. Interest accrued at the Wall Street Journal Prime Rate plus 1.00%, and was secured by the unallocated shares of the ESOP stock. This loan was refinanced in connection with the Conversion and Offering that occurred on October 16, 2014. In connection with the Conversion and Offering, the ESOP purchased 105,442 shares issued in the offering by obtaining a loan from the Company which was used to purchase both the additional shares and refinance the remaining outstanding balance on the loan from Community Bank N.A. There were 138,982.5 shares associated with the refinanced loan resulting in a total of 244,424.5 shares associated with the new loan provided by the Company. The ESOP loan from the Company has a ten year term and is being repaid in equal payments of principal and interest under a fixed rate of interest equal to 3.25% which was the prime rate of interest on the date of the closing of the offering. This ESOP loan from the Company, also referred to as an internally leveraged ESOP, does not appear as a liability on the Company’s consolidated statement of condition as of December 31, 2020 in accordance with ASC 718-40-25-9d . In accordance with the payment of principal on the loan, a proportionate number of shares are allocated to the employees over the ten year time horizon of the loan. Participants’ vesting interest in the shares of Company stock is at the rate of 20% per year. Compensation expense is recorded based on the number of shares released to the participants times the average market value of the Company’s stock over that same period. Dividends on unallocated shares, recorded as compensation expense on the income statement, are made available to the participants' account. The Company recorded $294,000 $24,000 91,659

A valuation allowance is provided when it is more likely than not that some portion, or all of the deferred tax assets, will not be realized. In assessing the need for a valuation allowance, management considers the scheduled reversal of the deferred tax liabilities, the level of historical taxable income and the projected future level of taxable income over the periods in which the temporary differences comprising the deferred tax assets will be deductible. Deferred income tax assets and liabilities are determined using the liability method. Under this method, the net deferred tax asset or liability is recognized for the future tax consequences. This is attributable to the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases as well as net operating and capital loss carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates applied to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income tax expense in the period that includes the enactment date. If current available evidence about the future raises doubt about the likelihood of a deferred tax asset being realized, a valuation allowance is established. The judgment about the level of future taxable income, including that which is considered capital, is inherently subjective and is reviewed on a continual basis as regulatory and business factors change. Banking corporations operating in New York State are taxed under the New York State General Business Corporation Franchise Tax provisions. Under this New York tax law, the tax rate on the business income base is 6.5%. However, various modifications are available to community banks (defined as banks with less than $8 billion in total assets) regarding certain deductions associated with interest income. Effective in January 2018, the Company adopted a modification methodology that at the time was newly made available under the New York State tax code, affecting how the Company’s state income tax liability is computed. Under this adopted methodology, management determined in the first quarter of 2019, it was unlikely that the Company would pay income taxes to New York State in future periods and therefore in the quarter ended March 31, 2019, the Company established, through a charge to earnings, a valuation allowance in the amount of $136,000 in order to reserve against deferred tax assets related to New York State income taxes. This valuation allowance against the value of those deferred tax assets was established to reduce the net deferred tax asset related to New York State income taxes to $-0-. Management is continuously monitoring its future tax consequences to determine if the Company’s deferred taxes are properly stated. In the first quarter of 2020, consistent with policy, management reviewed all facts and circumstances related to its deferred taxes and determined that based on the expected filings of future New York State tax returns, the valuation allowance created in 2019 was no longer needed. Therefore management elected to eliminate its New York State net deferred tax asset valuation allowance during the quarter ended March 31, 2020. In the first quarter of 2021, the Company filed amended New York State tax returns for 2015 through 2017 (the “carryback years”). The returns were amended from their original filings in order to file carryback claims utilizing New York State net operating losses generated under New York State tax law in 2018. As a result, the Company expects to receive $316,000 in tax refunds from New York State for taxes previously paid in the carryback years. This anticipated refund has been applied to the effective tax rate of the Company in 2020 in accordance with GAAP. In 2020, the Company’s effective tax rate was 15.9%, as compared to 21.4% in 2019. A reconciliation of the federal statutory income tax rate to the effective income tax rate for the years ended December 31, is as follows: 2020 2019 Federal statutory income tax rate 21.0 % 21.0 % State tax, net of federal benefit 2.0 (1.5 ) Tax-exempt interest income (0.9 ) (0.9 ) Increase in value of bank owned life insurance less premiums paid (1.1 ) (1.7 ) Change in valuation allowance (1.6 ) 2.5 NYS net operating loss carryback filing receivable, net of federal benefit (3.8 ) - Other (0.1 ) 1.9 Effective income tax rate - Pathfinder Bancorp, Inc. 15.5 % 21.3 % Minority interest 0.4 0.1 Effective income tax rate 15.9 % 21.4 %

Commitments And Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	NOTE 18: Commitments and Contingencies The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Such commitments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated statement of condition. The contractual amount of those commitments to extend credit reflects the extent of involvement the Company has in this particular class of financial instrument. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual amount of the instrument. The Company uses the same credit policies in making commitments as it does for on-balance sheet instruments. At December 31, 2020 and 2019, the following financial instruments were outstanding whose contract amounts represent credit risk: Contract Amount (In thousands) 2020 2019 Commitments to grant loans $ 58,217 $ 47,606 Unfunded commitments under lines of credit 102,404 81,038 Unfunded commitments related to construction loans in progress 6,103 3,214 Standby letters of credit 2,450 2,082 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since some of the commitment amounts are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the counter party. Collateral held varies but may include residential real estate and income-producing commercial properties. Loan commitments outstanding at December 31, 2020 with variable interest rates and fixed interest rates amounted to approximately $149.6 million and $19.6 million, respectively. These outstanding loan commitments carry current market rates. Unfunded commitments under standby letters of credit, revolving credit lines and overdraft protection agreements are commitments for possible future extensions of credit to existing customers. These lines of credit usually do not contain a specified maturity date and may not be drawn upon to the total extent to which the Company is committed. Letters of credit written are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Generally, all letters of credit, when issued have expiration dates within one year. The credit risk involved in issuing letters of credit is essentially the same as those that are involved in extending loan facilities to customers. The Company generally holds collateral and/or personal guarantees supporting these commitments. Management believes that the proceeds obtained through a liquidation of collateral and the enforcement of guarantees would be sufficient to cover the potential amount of future payments required under the corresponding guarantees.

Disclosure Of Restrictions On Dividends Loans And Advances Disclosure [Abstract]
DIVIDENDS AND RESTRICTIONS	NOTE 19: Dividends and Restrictions The Company's ability to pay dividends to its shareholders is largely dependent on the Bank's ability to pay dividends to the Company. In addition to state law requirements and the capital requirements discussed in Note 20, federal statutes, regulations and policies limit the circumstances under which the Bank may pay dividends. The amount of retained earnings legally available under these regulations approximated $17.8 million as of December 31, 2020. Dividends paid by the Bank to the Company would be prohibited if the effect thereof would cause the Bank’s capital to be reduced below applicable minimum capital requirements. The Bank made no dividend payments to the Company in the years ended December 31, 2020, December 31, 2019 or December 31, 2018. Capital adequacy is evaluated primarily by the use of ratios which measure capital against total assets, as well as against total assets that are weighted based on defined risk characteristics. The Company’s goal is to maintain a strong capital position, consistent with the risk profile of its banking operations. This strong capital position serves to support growth and expansion activities while at the same time exceeding regulatory standards. At December 31, 2020, the Bank met the regulatory definition of a “well-capitalized” institution, i.e. a leverage capital ratio exceeding 5%, a Tier 1 risk-based capital ratio exceeding 8%, Tier 1 common equity exceeding 6.5%, and a total risk-based capital ratio exceeding 10%. In addition to establishing the minimum regulatory capital requirements, the regulations limit capital distributions and certain discretionary bonus payments to management if the institution does not hold a “capital conservation buffer” consisting of 2.5% of common equity Tier 1 capital to risk-weighted assets above the amount necessary to meet its minimum risk-based capital requirements. The buffer is separate from the capital ratios required under the Prompt Corrective Action (“PCA”) standards. In order to avoid these restrictions, the capital conservation buffer effectively increases the minimum levels of the following capital to risk-weighted assets ratios: (1) Core Capital, (2) Total Capital and (3) Common Equity. The capital conservation buffer requirement is now fully implemented at 2.5% of risk-weighted assets. At December 31, 2020, the Bank exceeded all regulatory required minimum capital ratios, including the capital buffer requirements. As a result of the Economic Growth, Regulatory Relief, and Consumer Protection Act, the federal banking agencies developed a “Community Bank Leverage Ratio” (the ratio of a bank's tier 1 capital to average total consolidated assets) for financial institutions with assets of less than $10 billion. A “qualifying community bank” that exceeds this ratio will be deemed to be in compliance with all other capital and leverage requirements, including the capital requirements to be considered “well capitalized” under Prompt Corrective Action statutes. The federal banking agencies may consider a financial institution's risk profile when evaluating whether it qualifies as a community bank for purposes of the capital ratio requirement. The federal banking agencies have set the Community Bank Leverage Ratio at 9%. Pursuant to the CARES Act, the federal banking agencies issued final rules to set the Community Bank Leverage Ratio at 8% beginning in the second quarter of 2020 through the end of 2020. Beginning in 2021, the Community Bank Leverage Ratio will increase to 8.5% for the calendar year. Community banks will have until January 1, 2022, before the Community Bank Leverage Ratio requirement will return to 9%. A financial institution can elect to be subject to this new definition. The new rule took effect on January 1, 2020. The Bank did not elect to become subject to the Community Bank Leverage Ratio.

Regulatory Capital Requirements [Abstract]
REGULATORY MATTERS	NOTE 20: Regulatory Matters The Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of its assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain amounts and ratios (set forth in the table below) of total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined). As of December 31, 2020, the Bank’s most recent notification from the Federal Deposit Insurance Corporation categorized the Bank as “well-capitalized”, under the regulatory framework for prompt corrective action. To be categorized as “well-capitalized”, the Bank must maintain total risk-based, Tier 1 risk-based and Tier 1 leverage ratios as set forth in the tables below. There are no conditions or events since that notification that management believes have changed the Bank’s category. As noted above, the regulations also impose a “capital conservation buffer” consisting of 2.5% of common equity Tier 1 capital to risk-weighted assets above the amount necessary to meet its minimum risk-based capital requirements. The buffer is separate from the capital ratios required under the Prompt Corrective Action (“PCA”) standards and imposes restrictions on dividend distributions and discretionary bonuses. In order to avoid these restrictions, the capital conservation buffer effectively increases the minimum levels of the following capital to risk-weighted assets ratios: (1) Core Capital, (2) Total Capital and (3) Common Equity. The capital conservation buffer requirement is now fully implemented at 2.5% of risk-weighted assets. At December 31, 2020, the Bank exceeded all regulatory required minimum capital ratios, including the capital buffer requirements. The Bank’s actual capital amounts and ratios as of December 31, 2020 and 2019 are presented in the following table. Actual Minimum For Capital Adequacy Purposes Minimum To Be "Well-Capitalized" Under Prompt Corrective Provisions Minimum for Capital Adequacy With Buffer (Dollars in thousands) Amount Ratio Amount Ratio Amount Ratio Amount Ratio As of December 31, 2020: Total Core Capital (to Risk-Weighted Assets) $ 115,289 13.13 % $ 70,270 8.00 % $ 87,838 10.00 % $ 92,230 10.50 % Tier 1 Capital (to Risk-Weighted Assets) $ 104,287 11.87 % $ 52,703 6.00 % $ 70,270 8.00 % $ 74,662 8.50 % Tier 1 Common Equity (to Risk-Weighted Assets) $ 104,287 11.87 % $ 39,527 4.50 % $ 57,095 6.50 % $ 61,487 7.00 % Tier 1 Capital (to Assets) $ 104,287 8.63 % $ 48,314 4.00 % $ 60,392 5.00 % $ 60,392 5.00 % As of December 31, 2019: Total Core Capital (to Risk-Weighted Assets) $ 95,093 12.28 % $ 61,934 8.00 % $ 77,418 10.00 % $ 81,289 10.50 % Tier 1 Capital (to Risk-Weighted Assets) $ 86,424 11.16 % $ 46,451 6.00 % $ 61,934 8.00 % $ 65,805 8.50 % Tier 1 Common Equity (to Risk-Weighted Assets) $ 86,424 11.16 % $ 34,838 4.50 % $ 50,322 6.50 % $ 54,192 7.00 % Tier 1 Capital (to Assets) $ 86,424 8.20 % $ 42,175 4.00 % $ 52,719 5.00 % $ 52,719 5.00 % The Company’s goal is to maintain a strong capital position, consistent with the risk profile of its subsidiary banks that supports growth and expansion activities while at the same time exceeding regulatory standards . The Federal Reserve Board regulations require banks to maintain non-interest-earning reserves on deposit at the Federal Reserve Bank (“FRB”), against their transaction accounts (primarily negotiable order of withdrawal (“NOW”) and regular checking accounts). In March 2020, due to a change in in its approach to monetary policy due to the COVID-19 pandemic, the Federal Reserve Board announced an interim rule to amend Regulation D requirements and reduce reserve requirement ratios to zero. The Federal Reserve Board has indicated that it has no plans to re-impose reserve requirements, but may do so in the future. At December 31, 2019, the Bank held sufficient cash on hand to fully offset its reserve requirement and was therefore not required to maintain any additional reserve balances at the FRB.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
INTEREST RATE DERIVATIVE	NOTE 21: INTEREST RATE DERIVATIVE The Company is exposed to certain risks from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through the management of its core business activities. As part of the Company’s overall risk management processes, the Company manages its economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources and duration of certain balance sheet assets and liabilities. In the normal course of business, the Company also uses derivative financial instruments as an additional risk management tool. Financial derivatives are recorded at fair value as other assets. Among the array of interest rate derivative transactions potentially available to the Company are interest rate swaps. The Company uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps, designated as fair value hedges, involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed payments over the life of the agreements without the exchange of the underlying notional amount. The gain or loss on the derivative as well as the offsetting gain of loss on the hedged item attributable to the hedged risk are recognized in earnings. The Company entered into a pay-fixed/receive variable interest rate swap with a notional amount of $9.2 million in April 2019, which was designated as a fair value hedge associated with specific pools within the Company’s fixed-rate consumer loan portfolio. As of December 31, 2020 and 2019, the following amounts were recorded on the balance sheet related to the cumulative basis adjustments for fair value hedges: (In thousands) Carrying Amount of the Hedged Assets at December 31, 2020 Cumulative Amount of Fair Value Hedging Adjustment Included in The Carrying Amount of the Hedged Assets at December 31, 2020 Carrying Amount of the Hedged Assets at December 31, 2019 Cumulative Amount of Fair Value Hedging Adjustment Included in The Carrying Amount of the Hedged Assets at December 31, 2019 Line item on the balance sheet in which the hedged item is included: Loans receivable (1) $ 12,944 $ 53 $ 19,254 $ 75 (1) These amounts include the amortized cost basis of the closed portfolio used to designate the hedging relationship in which the hedged item is the remaining amortized cost of the last layer expected to be remaining at the end of the hedging relationship. At December 31, 2020 and December 31, 2019, the amortized cost of the basis of the closed portfolio used in the hedging relationship was $12.9 million and $19.3 million, the cumulative basis adjustment associated with the hedging relationship was $53,000 and $75,000, and the amount of the designated hedged item was $9.2 million and $9.2 million, respectively. At December 31, 2020 and December 31, 2019, the fair value of the derivative resulted in a net liability position of $55,000 and $92,000 under the agreement, recorded by the Company in other liabilities. In February 2020, the Company entered into an interest rate cap contract in the notional amount of $40.0 million, intended to reduce the Company’s exposure to potential rising interest rates. This contractual agreement has been designated as a cash flow hedge with changes in the fair value of the contract, net of changes in the fair value of the designated hedged liability (certain short-term certificates of deposit with rates of interest that are highly correlated to the 3-month LIBOR index) being accounted for through other comprehensive income. The term of the cap contract will commence on May 1, 2020 and expire on May 1, 2023. The Company paid $228,000 in a one-time premium for the cap contract and has no further contractual obligations to the counterparty over the three-year life of the contract. The premium will be amortized ratably over the contractual term of the cap contract with an annual average cost to the Company of approximately 19 basis points relative to the notional amount. The Company will potentially benefit during the term of this cap contract, in the manner described above, for the period of time that the 3-month LIBOR index exceeds 1.85% (the strike price). The cap contract had an immaterial affect on recorded interest expense in the year ended December 31, 2020. In March 2020, the Company entered into an interest rate swap contract in the notional amount of $40.0 million, intended to reduce the Company’s exposure to potential rising interest rates. This contractual agreement has been designated as a cash flow hedge with changes in the fair value of the contract, net of changes in the fair value of the designated hedged liability (certain short-term certificates of deposit with rates of interest that are highly correlated to the 3-month LIBOR index) being accounted for through other comprehensive income. The term of the swap contract will commence on May 15, 2020 and expire on May 15, 2023. Under the terms of the swap contract, the Company will be obligated to pay the contractual counterparty an annual rate of 1.39% (the strike price) times the notional amount of the contract. Simultaneously, for the duration of the swap contract, the counterparty will be obligated to pay the Company the annual rate of the 3-month LIBOR index, as determined each calendar quarter, times the notional contractual amount. The swap contract had no effect on recorded interest expense in the year ended December 31, 2020. (In thousands) December 31, 2020 December 31, 2019 Cash flow hedges: Total unamortized premium $ 204 $ - Fair market value adjustment interest rate cap (197 ) - Total unamortized cap 7 - Fair market value adjustment interest rate swap (1,111 ) - Total loss in comprehensive income $ (1,308 ) $ - The amounts of hedge ineffectiveness, recognized during the year ended December 31 2020, for cash flow hedges were not material to the Company’s consolidated results of operations. The Company had no cash flow hedges at December 31, 2019. Some or the entire amount included in accumulated other comprehensive loss would be reclassified into current earnings should a portion of, or the entire hedge no longer be considered effective, but at this time, management expects the hedge to remain fully effective during the remaining term of the swap. The changes in the fair values of the interest rate hedging agreements and the hedged items primarily result from the effects of changing interest rates and spreads. For the year ended, (In thousands) December 31, 2020 December 31, 2019 Balance as of December 31: $ - $ - Amount of losses recognized in other comprehensive income (1,308 ) - Losses in other comprehensive income: $ (1,308 ) $ - From time to time, the Company purchases high credit-quality securities with long maturity dates. In order to reduce the Company's exposure to potential declines in the fair value of such securities, particularly in a rising interest rate environment, the Company has elected to enter into fixed-pay, receive floating rate interest rate swap contracts, designated as fair value hedges. At December 31, 2020, the maturity dates of these swaps are matched exactly to the first call date of seven hedged securities. During 2020, the Company entered into five swap contracts of this type with a total notional amount of $16.3 million. The objective of the hedges is to protect the hedged securities of the Bank against changes in fair value due to changes in the benchmark interest rate. Changes in the fair value of the interest rate swap are expected to be “perfectly effective” in offsetting changes in the fair value of the hedged item attributable to changes in the LIBOR swap rate, the designated benchmark interest rate. The following table details the changes in the fair value of the hedged securities and the corresponding fair value hedges at December 31, 2020 and 2019: (In thousands) Carrying Amount of the Hedged Assets at December 31, 2020 Cumulative Amount of Fair Value Hedging Adjustment Included in The Carrying Amount of the Hedged Assets at December 31, 2020 Carrying Amount of the Hedged Assets at December 31, 2019 Cumulative Amount of Fair Value Hedging Adjustment Included in The Carrying Amount of the Hedged Assets at December 31, 2019 Line item on the balance sheet in which the hedged item is included: Available-for-sale securities (1) $ 17,055 $ (191 ) $ - $ - (1) These amounts include the amortized cost basis of the hedged securities used to designate the hedging relationship in which the hedged item is the remaining amortized cost of the last layer expected to be At December 31, 2020, the fair value of the derivative resulted in a net asset position of $191,000 under the agreement recorded by the Company in other assets. The fair value hedge had an immaterial effect on recorded interest income for the year ended December 31, 2020. The Company manages its potential credit exposure on interest rate swap transactions by entering into a bilateral credit support agreements with each counterparty. These agreements require collateralization of credit exposures beyond specified minimum threshold amounts. The Company posted cash in escrow of $1.6 million under collateral arrangements to satisfy collateral requirements associated with the interest rate swap contract.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS AND DISCLOSURES	NOTE 22: Fair Value MEASUREMENTS AND DISCLOSURES Accounting guidance related to fair value measurements and disclosures specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs have created the following fair value hierarchy: Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2 – Quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. Level 3 – Model-derived valuations in which one or more significant inputs or significant value drivers are unobservable. An asset’s or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs, minimize the use of unobservable inputs, to the extent possible, and considers counterparty credit risk in its assessment of fair value. The Company used the following methods and significant assumptions to estimate fair value: Investment securities: The fair values of securities available-for-sale are obtained from an independent third party and are based on quoted prices on nationally recognized securities exchanges where available (Level 1). If quoted prices are not available, fair values are measured by utilizing matrix pricing, which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted prices for specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2). Management made no adjustment to the fair value quotes that were received from the independent third party pricing service. Level 3 securities are assets whose fair value cannot be determined by using observable measures, such as market prices or pricing models. Level 3 assets are typically very illiquid, and fair values can only be calculated using estimates or risk-adjusted value ranges. Management applies known factors, such as currently applicable discount rates, to the valuation of those investments in order to determine fair value at the reporting date. The Company holds one corporate investment security with an aggregate amortized historical cost of $2.6 million and an aggregate fair market value of $2.7 million as of December 31, 2020. This security has a valuation that is determined using published net asset values (NAV) derived by an analysis of the security’s underlying assets. This security is comprised primarily of broadly-diversified real estate and adjustable-rate senior secured business loans and are traded in secondary markets on an infrequent basis. While these securities are redeemable at least annually through tender offers made by their respective issuers, the liquidation value of the securities may be below their stated NAVs and also subject to restrictions as to the amount of securities that can be redeemed at any single scheduled redemption. The Company anticipates that these securities will be redeemed by their respective issuers on indeterminate future dates as a consequence of the ultimate liquidation strategies employed by the management of these investments. The Company holds two equity security investments, with an aggregate value of $1.9 million at December 31, 2020, valued utilizing readily available market pricing (Level 1) observed from active trading on major national stock exchanges. Interest rate derivatives: The fair value of the interest rate derivatives, characterized as either fair value or cash flow hedges, are calculated based on a discounted cash flow model. All future floating rate cash flows are projected and both floating rate and fixed rate cash flows are discounted to the valuation date. The benchmark interest rate curve utilized for projecting cash flows and applying appropriate discount rates is built by obtaining publicly available third party market quotes for various swap maturity terms. Impaired loans: Impaired loans are those loans in which the Company has measured impairment based on the fair value of the loan’s collateral or the discounted value of expected future cash flows. Fair value is generally determined based upon market value evaluations by third parties of the properties and/or estimates by management of working capital collateral or discounted cash flows based upon expected proceeds. These appraisals may include up to three approaches to value: the sales comparison approach, the income approach (for income-producing property), and the cost approach. Management modifies the appraised values, if needed, to take into account recent developments in the market or other factors, such as, changes in absorption rates or market conditions from the time of valuation and anticipated sales values considering management’s plans for disposition. Such modifications to the appraised values could result in lower valuations of such collateral. Estimated costs to sell are based on current amounts of disposal costs for similar assets. These measurements are classified as Level 3 within the valuation hierarchy. Impaired loans are subject to nonrecurring fair value adjustment upon initial recognition or subsequent impairment. A portion of the allowance for loan losses is allocated to impaired loans if the value of such loans is deemed to be less than the unpaid balance. The following tables summarize assets measured at fair value on a recurring basis as of December 31, segregated by the level of valuation inputs within the hierarchy utilized to measure fair value: December 31, 2020 Total Fair (In thousands) Level 1 Level 2 Level 3 Value Available-for-Sale Portfolio Debt investment securities: US Treasury, agencies and GSEs $ - $ 6,416 $ - $ 6,416 State and political subdivisions - 23,753 - 23,753 Corporate - 9,943 - 9,943 Asset backed securities - 8,607 - 8,607 Residential mortgage-backed - US agency - 25,211 - 25,211 Collateralized mortgage obligations - US agency - 26,464 - 26,464 Collateralized mortgage obligations - Private label - 24,936 - 24,936 Total - 125,330 - 125,330 Corporate measured at NAV - - - 2,725 Total available-for-sale securities $ - $ 125,330 $ - $ 128,055 Marketable equity securities $ 1,850 $ - $ - $ 1,850 Interest rate swap derivative fair value hedge $ - $ (244 ) $ - $ (244 ) Interest rate swap derivative cash flow hedge $ - $ (1,308 ) $ - $ (1,308 ) December 31, 2019 Total Fair (In thousands) Level 1 Level 2 Level 3 Value Available-for-Sale Portfolio Debt investment securities: US Treasury, agencies and GSEs $ - $ 16,820 $ - $ 16,820 State and political subdivisions - 1,736 - 1,736 Corporate - 7,631 - 7,631 Asset backed securities - 13,232 - 13,232 Residential mortgage-backed - US agency - 18,980 - 18,980 Collateralized mortgage obligations - US agency - 30,785 - 30,785 Collateralized mortgage obligations - Private label - 16,821 - 16,821 Total - 106,005 - 106,005 Corporate measured at NAV - - - 4,923 Total available-for-sale securities $ - $ 106,005 $ - $ 110,928 Marketable equity securities $ - $ 534 $ - $ 534 The following tables summarize assets measured at fair value on a nonrecurring basis as of December 31, segregated by the level of valuation inputs within the hierarchy utilized to measure fair value: December 31, 2020 Total Fair (In thousands) Level 1 Level 2 Level 3 Value Impaired loans $ - $ - $ 14,701 $ 14,701 December 31, 2019 Total Fair (In thousands) Level 1 Level 2 Level 3 Value Impaired loans $ - $ - $ 3,105 $ 3,105 The following table presents additional quantitative information about assets measured at fair value on a nonrecurring basis and for which Level 3 inputs were used to determine fair value.

During the second quarter of 2020, one of the two investments, previously structured as an investment in a loan pool aggregator and accounted for at its net asset value, was substantially restructured by the issuing business entity, converted to an equity security and listed on a major national stock exchange. The fair value of that investment, previously accounted for at net asset value prior to the listing date, was $1.2 million at December 31, 2020. The fair value of this investment, determined at its stated net asset value at December 31, 2019 was $2.1 million. Also, during the second quarter of 2020, the entity issuing the Company’s other equity investment, whose fair value was previously determined using Level 2 inputs, was acquired by another financial institution that is actively listed on a public stock exchange. Immediately subsequent to this acquisition transaction, the fair value of this security was able to be determined using Level 1 inputs. The fair value of this investment was $682,000 and $534,000 at December 31, 2020 and December 31, 2019, respectively. Net changes in the fair value of these equity securities, whose fair valuations at each measurement date are now determined using Level 1 inputs, are accounted for as additions or subtractions to income, net of tax effects, in the period incurred. Required disclosures include fair value information of financial instruments, whether or not recognized in the consolidated statement of condition, for which it is practicable to estimate that value. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instrument. The Company has various processes and controls in place to ensure that fair value is reasonably estimated. The Company performs due diligence procedures over third-party pricing service providers in order to support their use in the valuation process. While the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Management uses its best judgment in estimating the fair value of the Company’s financial instruments; however, there are inherent weaknesses in any estimation technique. Therefore, for substantially all financial instruments, the fair value estimates herein are not necessarily indicative of the amounts the Company could have realized in a sales transaction on the dates indicated. The estimated fair value amounts have been measured as of their respective period-ends, and have not been re-evaluated or updated for purposes of these financial statements subsequent to those respective dates. As such, the estimated fair values of these financial instruments subsequent to the respective reporting dates may be different than the amounts reported at each period-end. FASB ASC Topic 820 for Fair Value Measurements and Disclosures, the financial assets and liabilities were valued at a price that represents the Company’s exit price or the price at which these instruments would be sold or transferred. The following information should not be interpreted as an estimate of the fair value of the entire Company since a fair value calculation is only provided for a limited portion of the Company’s assets and liabilities. Due to a wide range of valuation techniques and the degree of subjectivity used in making the estimates, comparisons between the Company’s disclosures and those of other companies may not be meaningful. The Company, in estimating its fair value disclosures for financial instruments, used the following methods and assumptions: Cash and cash equivalents – The carrying amounts of these assets approximate their fair value and are classified as Level 1. Federal Home Loan Bank stock – The carrying amount of these assets approximates their fair value and are classified as Level 2. Net loans – For variable-rate loans that re-price frequently, fair value is based on carrying amounts. The fair value of other loans (for example, fixed-rate commercial real estate loans, mortgage loans, and commercial and industrial loans) is estimated using discounted cash flow analysis, based on interest rates currently being offered in the market for loans with similar terms to borrowers of similar credit quality. Loan value estimates include judgments based on expected prepayment rates. The measurement of the fair value of loans, including impaired loans, is classified within Level 3 of the fair value hierarchy. Accrued interest receivable and payable – The carrying amount of these assets approximates their fair value and are classified as Level 1. Deposits – The fair values disclosed for demand deposits (e.g., interest-bearing and noninterest-bearing checking, passbook savings and certain types of money management accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts) and are classified within Level 1 of the fair value hierarchy. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered in the market on certificates of deposits to a schedule of aggregated expected monthly maturities on time deposits. Measurements of the fair value of time deposits are classified within Level 2 of the fair value hierarchy. Borrowings – Fixed/variable term “bullet” structures are valued using a replacement cost of funds approach. These borrowings are discounted to the FHLBNY advance curve. Option structured borrowings’ fair values are determined by the FHLB for borrowings that include a call or conversion option. If market pricing is not available from this source, current market indications from the FHLBNY are obtained and the borrowings are discounted to the FHLBNY advance curve less an appropriate spread to adjust for the option. These measurements are classified as Level 2 within the fair value hierarchy. Subordinated loans – The Company secures quotes from its pricing service based on a discounted cash flow methodology or utilizes observations of recent highly-similar transactions which result in a Level 2 classification. The carrying amounts and fair values of the Company’s financial instruments as of December 31 are presented in the following table: December 31, 2020 December 31, 2019 Fair Value Carrying Estimated Carrying Estimated (In thousands) Hierarchy Amounts Fair Values Amounts Fair Values Financial assets: Cash and cash equivalents 1 $ 43,464 $ 43,464 $ 20,160 $ 20,160 Investment securities - available-for-sale 2 125,330 125,330 106,005 106,005 Investment securities - available-for-sale NAV 2,725 2,725 4,923 4,923 Investment securities - marketable equity 1 1,850 1,850 - - Investment securities - marketable equity 2 - - 534 534 Investment securities - held-to-maturity 2 171,224 174,935 122,988 124,148 Federal Home Loan Bank stock 2 4,390 4,390 4,834 4,834 Net loans 3 812,718 816,626 772,782 767,654 Accrued interest receivable 1 4,549 4,549 3,712 3,712 Financial liabilities: Demand Deposits, Savings, NOW and MMDA 1 $ 598,683 $ 598,683 $ 460,293 $ 460,293 Time Deposits 2 397,224 398,863 421,600 422,409 Borrowings 2 82,050 84,065 93,125 93,643 Subordinated loans 2 39,400 39,416 15,128 14,921 Accrued interest payable 2 193 193 396 396 Interest rate swap derivative fair value hedges 2 244 244 92 92 Interest rate swap derivative cash flow hedges 2 1,308 1,308 - -

RELATED PARTY TRANSACTIONS	NOTE 24: RELATED PARTY TRANSACTIONS In the ordinary course of business, the Company has granted loans to certain directors, executive officers and their affiliates (collectively referred to as “related parties”). None of the related party loans were classified as nonaccrual, past due, restructured, or potential problem loans at December 31, 2020 or 2019. The following represents the activity associated with loans to related parties during the year ended December 31, 2020: (In thousands) 2020 2019 Balance at the beginning of the year $ 19,301 $ 16,480 Originations and related party additions 4,899 6,910 Principal payments and related party removals (1,990 ) (4,089 ) Balance at the end of the year $ 22,210 $ 19,301 Deposit accounts of each related party at December 31, 2020 and December 31, 2019 were $ 12.5 In December 2020, the Bank sold a parcel of property and an existing dwelling, that was in the process of being developed into a new branch location, to a limited liability corporation (“LLC”) co-owned by a member of its board of directors. The purchase price of the property was $612,000. The property will continue to be developed by the LLC up to a total project cost of $2.8 million. All development costs over $2.8 million, which are expected to be partially offset by available tax credits, will be the responsibility of the Bank and treated in the future as leasehold improvements. In January of 2021, the Bank entered into a lease agreement with the LLC to lease the entire building located at the site in Syracuse, New York and an adjacent property. Once these sites are developed, the Bank intends to operate the building as a full-service branch banking facility. The term of this lease shall be for a period of thirty-two years and sixty days commencing on February 1, 2021. The Bank will pay the landlord, as total rent for the first twelve months of the lease, the annual sum of $201,000. After the first anniversary of the lease, and for every 12 month period following until the end of the lease term, the Bank will pay the landlord, as total rent, the annual sum of $262,000.

Conversion And Reorganization [Abstract]
CONVERSION AND REORGANIZATION	NOTE 25: CONVERSION AND REORGANIZATION On October 16, 2014, the former Pathfinder Bancorp (“former Pathfinder”) completed the conversion and reorganization pursuant to which Pathfinder Bancorp, MHC converted to the stock holding company form of organization under a “second step” conversion (the “Conversion”), and the Bank reorganized from the two-tier mutual holding company structure to the stock holding company structure. Prior to the completion of the Conversion, the MHC owned approximately 60.4% of the common stock of the Company. The Company, the new stock holding company for Pathfinder Bank, sold 2,636,053 shares of common stock at $10.00 per share, for gross offering proceeds of $26.4 million in its stock offering. In addition, $197,000 in cash was received by the Company from the MHC upon it ceasing to exist. Concurrent with the completion of the offering, shares of common stock of the Company owned by the public were exchanged for shares of the Company’s common stock so that the shareholders now own approximately the same percentage of the Company’s common stock as they owned of the former Pathfinder’s common stock immediately prior to the Conversion. Shareholders of the former Pathfinder received 1.6472 shares of the Company’s common stock for each share of the former Pathfinder’s common stock that they owned immediately prior to completion of the transaction. As a result of the offering and the exchange of shares, the Company had 4,353,850 shares outstanding at December 31, 2014. The Company has 4,709,238 and 4,531,383 shares outstanding at December 31, 2019 and December 31, 2020, respectively. The Conversion was accounted for as a change in corporate form with no resulting change in the historical basis of the Company’s assets, liabilities, and equity. Costs related to the offering were primarily marketing fees paid to the Company’s investment banking firm, legal and professional fees, registration fees, printing and mailing costs and totaled $1.5 million. Accordingly, net proceeds were $24.9 million. In addition, as part of the Conversion and dissolution of the MHC, the Company received $197,000 of cash previously held by the MHC. As a result of the Conversion and Offering, Pathfinder Bancorp, Inc., a federal corporation, was succeeded by a new fully public Maryland corporation with the same name and the MHC ceased to exist. The shares of common stock sold in the offering and issued began trading on the NASDAQ Capital Market on October 17, 2014 under the trading symbol “PBHC.” In accordance with Board of Governors of the Federal Reserve System regulations, at the time of the reorganization, the Company substantially restricted retained earnings by establishing a liquidation account. The liquidation account will be maintained for the benefit of eligible account holders who continue to maintain their accounts at the Bank after conversion. The Bank will establish a parallel liquidation account to support the Company’s liquidation account in the event the Company does not have sufficient assets to fund its obligations under its liquidation account. The liquidation accounts will be reduced annually to the extent that eligible account holders have reduced their qualifying deposits. Subsequent increases will not restore an eligible account holder’s interest in the liquidation accounts. In the event of a complete liquidation of the Bank or the Company, each account holder will be entitled to receive a distribution in an amount proportionate to the adjusted qualifying account balances then held. The Bank may not pay dividends if those dividends would reduce equity capital below the required liquidation account amount.

Transaction-based fees are recognized at the time the transaction is executed, which is the same time the Company’s performance obligation is satisfied. Account maintenance fees are earned over the course of the month as the monthly maintenance performance obligation to the customer is satisfied. • Fee income – Revenue is earned through commissions on insurance and securities sales, ATM surcharge fees, and banking house rents collected. The Company earns investment advisory fee income by providing investment management services to customers under investment management contracts. As the direction of investment management accounts is provided over time, the performance obligation to investment management customers is satisfied over time, and therefore, revenue is recognized over time. • Card income – Card income consists of interchange fees from consumer debit card networks and other related services. Interchange rates are set by the card networks. Interchange fees are based on purchase volumes and other factors and are recognized as transactions occur. • Mortgage fee income and realized gain on sale of loans and foreclosed real estate – Revenue from mortgage fee income and realized gain on sale of loans and foreclosed real estate is earned through the origination of residential and commercial mortgage loans, sales of one-to-four family residential mortgage loans, sales of government guarantees portions of SBA loans, and sales of foreclosed real estate, and is earned as the transaction occurs.

COVID-19

COVID-19	12 Months Ended
	Dec. 31, 2020
Extraordinary And Unusual Items [Abstract]
COVID-19	NOTE 29: COVID-19 In early January 2020, the World Health Organization issued an alert that a novel coronavirus outbreak was emanating from Wuhan, Hubei Province in China. Over the course of the next several weeks, the outbreak continued to spread to various regions of the world, prompting the World Health Organization to declare COVID-19 a global pandemic on March 11, 2020. In the United States, by the end of March 2020, the rapid spread of the COVID-19 virus invoked various Federal and New York State authorities to make emergency declarations and issue executive orders to limit the spread of the disease. Measures included restrictions on international and domestic travel, limitations on public gatherings, implementation of social distancing and sanitization protocols, school closings, orders to shelter in place and mandates to close all non-essential businesses to the public. To widely varying degrees, largely dependent upon the level of regional and national outbreaks and the resultant levels of strain on available medical resources, these very substantial mandated curtailments of social and economic activity had been relaxed globally in the third and fourth quarters of 2020. However, the number of reported positive cases (partly due to increased testing) in the United States have continued to be at high levels as of the date of this filing and new strains of the virus, potentially more contagious and more virulent have been reported in many parts of the world, including in the United States. Further, there still are virtually no localities within the United States that have completely returned to substantively normal business and social activities at the time of this filing. As a result of the initial and continuing outbreak, and governmental responses thereto, the spread of the coronavirus has caused us to modify our business practices, including employee travel, employee work locations, and cancellation of physical participation in meetings, events and conferences. The Company has many employees working remotely and has significantly reduced physical customer contact with employees and other customers. Initially, branch activities were limited to drive-thru transactions whenever possible, teleconferencing and in-branch “appointments only” services. The Bank’s branches are now fully accessible to the public but remain in strict compliance with all applicable social distancing and sanitization guidelines. Since the start of the pandemic, transactional volume has also increased through the Bank’s telephone, mobile and internet banking channels. We will take further actions, focused on safety, as may be required by government authorities or that we determine to be in the best interests of our employees, customers and business partners. Concerns about the spread of the disease and its anticipated negative impact on economic activity, severely disrupted both domestic and international financial markets prompting the world’s central banks to inject significant amounts of monetary stimulus into their respective economies. In the United States, the Federal Reserve System’s Federal Open Market Committee, swiftly cut the target Federal Funds rate to a range of 0% to 0.25%, where it remains as of the date of this filing. The reductions in the Fed funds target rate included a 50 basis point reduction in the target federal funds rate on March 3, 2020 and an additional 100 basis point reduction on March 15, 2020. In addition, the Federal Reserve initiated various market support programs to ease the stress on financial markets. This significant reduction in short-term interest rates has reduced, and will continue to reduce, the Bank’s cost of funds and interest earning-asset yields. The long-term effects of the current interest rate environment, resulting from government and central bank responses to the pandemic, on the Bank’s net interest margin cannot be predicted with certainty at this time. The Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), signed into law on March 27, 2020, provided financial assistance in various forms to both businesses and consumers, including the establishment and funding of the Paycheck Protection Program (“PPP”). In addition, the CARES Act also created many directives affecting the operations of financial services providers, such as the Company, including a forbearance program for federally-backed mortgage loans and protections for borrowers from negative credit reporting due to loan accommodations related to the national emergency. The banking regulatory agencies have likewise issued guidance encouraging financial institutions to work prudently with borrowers who are, or may be, unable to meet their contractual payment obligations because of the effects of COVID-19. The Company has worked to assist its business and consumer customers affected by COVID-19. On December 27, 2020, following passage by the United States Congress, President Donald J. Trump signed into law the Consolidated Appropriations Act, 2021 which included the Coronavirus Response and Relief Supplemental Appropriations Act (“CRRSAA”). The intent of this legislation was to provide another round of Economic Impact Payments to eligible individuals and families, renew the PPP to support small businesses and their employees, ensure needed access to unemployment benefits for Americans who have lost their jobs due to COVID-19, and provide additional funding for schools, vaccine distribution, and other important sectors of the economy. While CRRSSA is expected to benefit the economic recovery and be supportive of the Company’s business activities, the effect of this legislation on the operations of the Company cannot be determined with certainty at this time. The Bank participated in the PPP funded by the U.S. Treasury Department and administered by the U.S. SBA pursuant to the CARES Act and subsequent legislation. PPP loans have an interest rate of 1.0% and a two-year or five-year loan term to maturity. The SBA guarantees 100% of the PPP loans made to eligible borrowers. The entire principal amount of the borrower’s PPP loan, including any accrued interest, is eligible to be reduced by the loan forgiveness amount under the PPP so long as employee and compensation levels of the business are maintained and the loan proceeds are used for qualifying expenses. Through December 31, 2020, the Bank has received approval from the SBA for 699 loans totaling approximately $75.3 million through this program. The program was extended at least through the first quarter of 2021. The Bank is participating in the second round of PPP. The Bank is now also assisting borrowers with the loan forgiveness phase of the process. As of this filing, the Company has submitted 312 loans totaling approximately $33.7 million to the SBA for forgiveness. The Bank collected $2.3 million in fees associated with PPP lending activities during 2020 and recognized $1.1 million of those fees as interest income during the year. Accordingly, $1.2 million in deferred fee income was subtracted from the carrying value of the PPP loans held in portfolio at December 31, 2020 and will be recognized in future periods. Borrowers that were delinquent in their payments to the Bank, prior to requesting a COVID-19 related financial hardship payment deferral were reviewed on a case by case basis for troubled debt restructure classification and non-performing loan status. In the instances where the Company granted a payment deferral to a delinquent borrower because of COVID-19, the borrower’s delinquency status was frozen as of February 29, 2020, and their loans will continue to be reported as delinquent during the deferment period based on their delinquency status as of that date. The long-term collectability of deferred loan payments will depend on many factors, including the future progression of the pandemic, potential medical breakthroughs in therapeutic treatments and/or vaccines, the pace of vaccine distributions, further economic stimulus from government authorities, the rate at which governmental restrictions on business activities are relaxed and the adequacy and sustainability of other sources of repayment such as loan collateral. Consistent with industry regulatory guidance, borrowers that were granted COVID-19 related deferrals but were otherwise current on loan payments will continue to have their loans reported as current loans during the agreed upon deferral period(s), accrue interest and not be accounted for as troubled debt restructurings. Through December 31, 2020, the Bank granted payment deferral requests for an initial period of 90 days on 618 loans representing approximately $137.4 million of existing loan balances. Upon the receipt of borrower requests, additional 90 day deferral periods were generally granted. Of these granted deferrals, 303 loans, totaling $24.0 million, were residential mortgage or consumer loans. At December 31, 2020, 265 residential and consumer loans, totaling $21.3 million, have been returned to non-deferral status. Of these granted deferrals, 315 loans, totaling $113.3 million, were commercial real estate or other commercial and industrial loans. At December 31, 2020, 291 commercial real estate or other commercial and industrial loans, totaling $98.9 million, have been returned to non-deferral status. Therefore, at December 31, 2020, 38 residential mortgage and consumer loans, totaling $2.7 million and 24 commercial real estate and other commercial and industrial loans, totaling $14.4 million remained in deferral status. These loans still in deferral status therefore totaled $17.1 million and represented 2.1% of all loans outstanding at December 31, 2020. After consultations with certain of these commercial loan borrowers, 11 loans, representing $8.3 million, have been granted an additional 90 day deferral period beyond 180 days as of December 31, 2020. These loans are included in the $17.1 million in loans still in deferred status at December 31, 2020. On an extremely limited basis, a dditional deferral periods will potentially be granted subject to further analysis and discussion with specific borrowers. To the extent that such modifications meet the criteria described they have not been classified as troubled debt restructurings nor classified as nonperforming at December 31, 2020. Loans not granted additional deferral periods have been, and will continue to be, categorized as nonaccrual loans if the borrowers fail to make the first scheduled payment following the end of the deferral period. The future performance of the Company’s loan portfolios with respect to credit losses will be highly dependent upon the course and duration, both nationally and within the Company’s market area, of the public health and economic factors related to the pandemic, as well as the concentrations in the Company’s loan portfolio. Concentrations of loans within a portfolio that are made to a singular borrower, to a related group of borrowers, or to a limited number of industries, are generally considered to be additional risk factors in estimating future credit losses. Therefore, the Company monitors all of its credit relationships to ensure that the total loan amounts extended to one borrower, or to a related group of borrowers, does not exceed the maximum permissible levels defined by applicable regulation or the Company’s generally more restrictive internal policy limits. Loans to a single borrower, or to a related group of borrowers, are referred to as related credits. Total related credits encompass all related or affiliated borrower loan balances, including available unused lines of credit, for both personal and business loans. At December 31, 2020, In addition, the future credit-related performance of a loan portfolio generally depends upon the types of loans within the portfolio, concentrations by type of loan and the quality of the collateral securing the loans. The following table details the Company's loan portfolio by collateral type within major categories as of December 31, 2020: (Dollars in thousands) Balance Number of Loans Average Loan Balance Minimum/ Maximum Loan Balance Allowance for Loan Losses Percent of Total Loans Residential Mortgage Loans $ 235,392 2,154 $ 109 $ 0 - $ 1,546 $ 931 29 % Commercial Real Estate: Mixed Use $ 48,828 53 $ 921 $ 49 - $ 7,433 $ 815 6 % Multi-Family Residential 46,394 59 786 26 - 6,275 774 6 % Hotels and Motels 35,434 10 3,543 340 - 11,500 591 4 % Office 31,467 61 516 9 - 4,851 525 3 % Retail 21,692 44 493 34 - 5,155 362 3 % 1-4 Family Residential 18,518 151 123 - - 1,236 309 2 % Automobile Dealership 16,430 10 1,643 169 - 6,792 274 2 % Warehouse 11,706 15 780 0 - 2,728 195 1 % Recreation/ Golf Course/ Marina 11,624 15 775 26 - 3,150 194 1 % Skilled Nursing Facility 10,661 2 5,331 3,800 - 6,861 178 1 % Manufacturing/Industrial 7,511 15 501 93 - 1,418 125 1 % Restaurant 6,321 23 275 46 - 1,271 105 1 % Automobile Repair 4,762 10 476 60 - 2,332 80 1 % Not-For-Profit & Community Service Real Estate 3,323 3 1,108 107 - 1,638 56 1 % Hospitals 3,182 2 1,591 77 - 3,105 53 1 % Land 2,412 4 603 72 - 2,000 40 0 % All Other 6,006 31 194 16 - 745 100 1 % Total Commercial Real Estate Loans $ 286,271 508 564 4,776 35 % Commercial and Industrial: Secured Term Loans $ 60,934 368 $ 166 $ - - $ 4,735 $ 1,294 7 % Unsecured Term Loans 17,695 122 145 1 - 2,244 376 2 % Secured Lines of Credit 38,938 266 146 - - 5,000 2,373 5 % Unsecured Lines of Credit 10,165 134 76 - - 2,783 619 1 % Total Commercial and Industrial Loans $ 127,732 890 144 4,662 15 % Tax Exempt Loans $ 7,166 24 $ 299 $ 6 - $ 2,251 $ 1 1 % Paycheck Protection Loans $ 60,643 599 $ 101 $ 0 - $ 3,001 $ - 7 % Consumer: Home Equity Lines of Credit $ 38,624 1,022 $ 38 0 - $ 336 $ 739 5 % Vehicle 26,265 1,750 15 0 - 357 416 3 % Consumer Secured 18,131 694 26 21 - 131 287 2 % Consumer Unsecured 24,074 5,608 4 0 - 109 381 3 % All Others 2,435 961 3 0 - 498 39 0 % Total Consumer Loans 109,529 10,035 11 1,862 13 % Net deferred loan fees (1,238 ) - - - - Unallocated allowance for loan losses - - - 545 - Total Loans $ 825,495 14,210 $ 58 $ 12,777 100 %

Subsequent Events [Abstract]
Subsequent Events	NOTE 30: SUBSEQUENT EVENTS On March 29, 2021, the Company announced that its Board of Directors had declared a cash dividend of $0.07 per common and preferred share, and a cash dividend of $0.07 per notional share for the issued Warrant. The dividend will be payable on May 7, 2021 to shareholders of record on April 15, 2021. In first quarter of 2021, the Company exercised its existing contractual option and issued a Notice of Redemption (“NOR”) to the holders of the 2015 Subordinated Loan, which was scheduled to mature on October 1, 2025. With the issuance of this NOR, the Company is now obligated to redeem the $10.0 million 2015 Subordinated Loan, plus accrued interest, on April 1, 2021. The Company plans to use components of its existing liquidity position to redeem this borrowing. The redemption of this borrowing will prospectively reduce the Company’s interest expense by $625,000 per year.

Accounting Policies [Abstract]
Nature of Operations	Nature of Operations The accompanying consolidated financial statements include the accounts of Pathfinder Bancorp, Inc. (the “Company”) and its wholly owned subsidiary, Pathfinder Bank (the “Bank”). The Company is a Maryland corporation headquartered in Oswego, New York. On October 16, 2014, the Company completed its conversion from the mutual holding company structure and the related public offering and is now a stock holding company that is fully owned by the public. As a result of the conversion, the mutual holding company and former mid-tier holding company were merged into Pathfinder Bancorp, Inc. The primary business of the Company is its investment in Pathfinder Bank (the "Bank") which is 100% owned by the Company. The Bank has two wholly owned operating subsidiaries, Pathfinder Risk Management Company, Inc. (“PRMC”) and Whispering Oaks Development Corp. All significant inter-company accounts and activity have been eliminated in consolidation. Although the Company owns, through its subsidiary PRMC, 51% of the membership interest in FitzGibbons Agency, LLC (“FitzGibbons”), the Company is required to consolidate 100% of FitzGibbons within the consolidated financial statements. The 49% of which the Company does not own is accounted for separately as noncontrolling interests within the consolidated financial statements. The Company received $24.9 million in net proceeds from the sale of approximately 2.6 million shares of common stock as a result of the Conversion in October 2014. In October 2015, the Company executed the issuance of a $10.0 million non-amortizing Subordinated Loan and subsequently used those proceeds in February 2016 to substantially fund the full retirement of $13.0 million in SBLF Preferred stock. The Company received $19.6 million in net proceeds from the sale of 37,700 shares of common stock and 1,155,283 shares of preferred stock as a result of the Private Placement in May 2019. The Company has seven branch offices located in Oswego County, three branch offices in Onondaga County and one limited purpose office in Oneida County. The Company is primarily engaged in the business of attracting deposits from the general public in the Company’s market area, and investing such deposits, together with other sources of funds, in loans secured by commercial real estate, business assets, one-to-four family residential real estate and investment securities.
Discussion of COVID-19 Pandemic	Discussion of COVID-19 Pandemic A discussion of the effect of the COVID-19 pandemic on the operations of the Company is contained herein in Note 29.
Use of Estimates in the Preparation of Consolidated Financial Statements	Use of Estimates in the Preparation of Consolidated Financial Statements The preparation of consolidated financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Management has identified the allowance for loan losses, deferred income taxes, pension obligations, the annual evaluation of the Company’s goodwill for possible impairment and the evaluation of investment securities for other than temporary impairment and the estimation of fair values for accounting and disclosure purposes to be the accounting areas that require the most subjective and complex judgments, and as such, could be the most subject to revision as new information becomes available. The Company is subject to the regulations of various governmental agencies. The Company also undergoes periodic examinations by the regulatory agencies which may subject it to further changes with respect to asset valuations, amounts of required loss allowances, and operating restrictions resulting from the regulators' judgments based on information available to them at the time of their examinations.
Significant Group Concentrations of Credit Risk	Significant Group Concentrations of Credit Risk Most of the Company’s activities are with customers located primarily in Oswego and Onondaga counties of New York State. A large portion of the Company’s portfolio is centered in residential and commercial real estate. The Company closely monitors real estate collateral values and requires additional reviews of commercial real estate appraisals by a qualified third party for commercial real estate loans in excess of $400,000. All residential loan appraisals are reviewed by an individual or third party who is independent of the loan origination or approval process and was not involved in the approval of appraisers or selection of the appraiser for the transaction, and has no direct or indirect interest, financial or otherwise in the property or the transaction.
Advertising	Advertising The Company generally follows the policy of charging the costs of advertising to expense as incurred. Expenditures for new marketing and advertising material designs and/or media content, related to specifically-identifiable marketing campaigns are capitalized and expensed over the estimated life of the campaign. Such periods of time are generally 12-24 months in duration and do not exceed 36 months.
Noncontrolling Interest	Noncontrolling Interest Noncontrolling interest represents the portion of ownership and profit or loss that is attributable to the minority owners of FitzGibbons.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash on hand, amounts due from banks and interest-bearing deposits (with original maturity of three months or less).
Investment Securities	Investment Securities The Company classifies investment securities as either available-for-sale or held-to-maturity. The Company does not hold any securities considered to be trading. Available-for-sale securities are reported at fair value, with net unrealized gains and losses reflected as a separate component of shareholders’ equity, net of the applicable income tax effect. Held-to-maturity securities are those that the Company has the ability and intent to hold until maturity and are reported at amortized cost. Gains or losses on investment security transactions are based on the amortized cost of the specific securities sold. Premiums and discounts on securities are amortized and accreted into income using the interest method over the period to maturity. The Company records its investment in marketable equity securities (“MES”) at fair value. Changes in the fair value of MES are recorded as additions to, or subtractions from, net income in the period that the change occurs. These changes in fair value are separately disclosed as gains (losses) on equity securities on the Consolidated Statements of Income. Note 4 to the consolidated financial statements includes additional information about the Company’s accounting policies with respect to the impairment of investment securities.
Federal Home Loan Bank Stock	Federal Home Loan Bank Stock Federal law requires a member institution of the Federal Home Loan Bank (“FHLB”) system to hold stock of its district FHLB according to a predetermined formula. The stock is carried at cost.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of financial assets, including sales of loans and loan participations, are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) 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 (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Loans	Loans The Company grants mortgage, commercial, municipal, and consumer loans to customers. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are stated at their outstanding unpaid principal balances, less the allowance for loan losses plus net deferred loan origination costs. The ability of the Company’s debtors to honor their contracts is dependent upon the real estate and general economic conditions in the market area. Interest income is generally recognized when income is earned using the interest method. Nonrefundable loan fees received and related direct origination costs incurred are deferred and amortized over the life of the loan using the interest method, resulting in a constant effective yield over the loan term. Deferred fees are recognized into income and deferred costs are charged to income immediately upon prepayment of the related loan. The loans receivable portfolio is segmented into residential mortgage, commercial and consumer loans. The residential mortgage segment consists of one-to-four family first-lien residential mortgages and construction loans. Commercial loans consist of the following classes: real estate, lines of credit, other commercial and industrial, and tax-exempt loans. Consumer loans include both home equity lines of credit and loans with junior liens and other consumer loans.
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses represents management’s estimate of losses inherent in the loan portfolio as of the date of the statement of condition and it is recorded as a reduction of loans. The allowance is increased by the provision for loan losses, and decreased by charge-offs, net of recoveries. Loans deemed to be uncollectible are charged against the allowance for loan losses, and subsequent recoveries, if any, are credited to the allowance. All, or part, of the principal balance of loans receivable are charged off to the allowance as soon as it is determined that the repayment of all, or part, of the principal balance is highly unlikely. Non-residential consumer loans are generally charged off no later than 120 days past due on a contractual basis, unless productive collection efforts are providing results. Consumer loans may be charged off earlier in the event of bankruptcy, or if there is an amount that is deemed uncollectible. No portion of the allowance for loan losses is restricted to any individual loan product and the entire allowance is available to absorb any and all loan losses. The allowance for loan losses is maintained at a level considered adequate to provide for losses that can be reasonably anticipated. Management performs a quarterly evaluation of the adequacy of the allowance. The allowance is based on three major components which are; specific components for larger loans, recent historical losses and several qualitative factors applied to a general pool of loans, and an unallocated component. The first component is the specific component that relates to loans that are classified as impaired. For these loans, an allowance is established when the discounted cash flows or collateral value of the impaired loan is lower than the carrying value of that loan. The second or general component covers pools of loans, by loan class, not considered impaired, smaller balance homogeneous loans, such as residential real estate, home equity and other consumer loans. These pools of loans are evaluated for loss exposure first based on historical loss rates for each of these categories of loans. The ratio of net charge-offs to loans outstanding within each product class, over the most recent eight quarters, lagged by one quarter, is used to generate the historical loss rates. In addition, qualitative factors are added to the historical loss rates in arriving at the total allowance for loan loss need for this general pool of loans. The qualitative factors include changes in national and local economic trends, the rate of growth in the portfolio, trends of delinquencies and nonaccrual balances, changes in loan policy, and changes in lending management experience and related staffing. Each factor is assigned a value to reflect improving, stable or declining conditions based on management’s best judgment using relevant information available at the time of the evaluation. These qualitative factors, applied to each product class, make the evaluation inherently subjective, as it requires material estimates that may be susceptible to significant revision as more information becomes available. Adjustments to the factors are supported through documentation of changes in conditions in a narrative accompanying the allowance for loan loss analysis and calculation. As a result of the COVID-19 pandemic, the Company’s management extensively reviewed a broad array of econometric projections and the potential effect of changes in those projections on anticipated loan performance. As a result, certain qualitative factors were substantially modified during 2020 in order to determine the adequacy of the allowance for loan losses during the year and at December 31, 2020. The third or unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio and generally comprises less than 10% of the total allowance for loan loss. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and shortfalls on a case-by case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length and reason for the delay, the borrower’s prior payment record and the amount of shortfall in relation to what is owed. Impairment is measured by either the present value of the expected future cash flows discounted at the loan’s effective interest rate or the fair value of the underlying collateral, if the loan is collateral dependent. The majority of the Company’s loans utilize the fair value of the underlying collateral. The CARES Act, signed into law on March 27, 2020, provided financial assistance in various forms to both businesses and consumers. One of the technical provisions of the CARES Act was to allow financial institutions not to characterize loan modifications specifically related to the COVID-19 pandemic as TDRs although financial institutions must make impairment determinations for accounting purposes if certain impairment triggers are met. Notwithstanding the Bank’s policies with respect to impaired and potentially impaired loans, as discussed above, certain loans on deferred payment status were not classified as impaired or TDRs at December 31, 2020, as a result of the application of the provisions of the CARES Act. An allowance for loan loss is established for an impaired loan if its carrying value exceeds its estimated fair value. The estimated fair values of substantially all of the Company’s impaired loans are measured based on the estimated fair value of the loan’s collateral. For loans secured by real estate, estimated fair values are determined primarily through third-party appraisals, less costs to sell. Appraised values are discounted to arrive at the estimated selling price of the collateral, which is considered to be the estimated fair value. The discounts also include estimated costs to sell the property. For commercial and industrial loans secured by non-real estate collateral, such as accounts receivable, inventory and equipment, estimated fair values are determined based on the borrower’s financial statements, inventory reports, accounts receivable agings or equipment appraisals or invoices. Indications of value from these sources are generally discounted based on the age of the financial information or the quality of the assets. Large groups of homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual residential mortgage loans less than $300,000, home equity and other consumer loans for impairment disclosures, unless such loans are related to borrowers with impaired commercial loans or they are subject to a troubled debt restructuring agreement. Loans that are related to borrowers with impaired commercial loans or are subject to a troubled debt restructuring agreement are evaluated individually for impairment. Commercial loans whose terms are modified are classified as troubled debt restructurings if the Company grants such borrowers concessions and it is deemed that those borrowers are experiencing financial difficulty. Concessions granted under a troubled debt restructuring generally include but are not limited to a temporary reduction in the interest rate or an extension of a loan’s stated maturity date. Commercial loans classified as troubled debt restructurings are designated as impaired and evaluated individually as discussed above. The allowance calculation methodology includes further segregation of loan classes into risk rating categories. The borrower’s overall financial condition, repayment sources, guarantors and value of the collateral, if appropriate, are evaluated not less than annually for commercial loans or when credit deficiencies arise on all loans. Credit quality risk ratings include regulatory classifications of special mention, substandard, doubtful and loss. See Note 5 for a description of these regulatory classifications. In addition, Federal and State regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan losses and may require the Company to recognize additions to the allowance based on their judgments about information available to them at the time of their examination, which may not be currently available to management. Based on management’s comprehensive analysis of the loan portfolio, management believes the current level of the allowance for loan losses is adequate.
Income Recognition on Impaired and Nonaccrual Loans	Income Recognition on Impaired and Nonaccrual Loans With the exception of loans in deferral at December 31, 2020 as a result of COVID-19 pandemic-related factors, for all classes of loans receivable, the accrual of interest is discontinued when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about further collectability of principal or interest, even though the loan may be currently performing. A loan may remain on accrual status if it is either well secured or guaranteed and in the process of collection. When a loan is placed on nonaccrual status, unpaid interest is reversed and charged to interest income. Interest received on nonaccrual loans, including impaired loans, generally is either applied against principal or reported as interest income, according to management’s judgment as to the collectability of principal. Generally, loans are restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time, generally six months, and the ultimate collectability of the total contractual principal and interest is no longer in doubt. Nonaccrual troubled debt restructurings are restored to accrual status if principal and interest payments, under the modified terms, are current for six consecutive months after modification. For nonaccrual loans, when future collectability of the recorded loan balance is expected, interest income may be recognized on a cash basis. In the case where a nonaccrual loan had been partially charged off, recognition of interest on a cash basis is limited to that which would have been recognized on the recorded loan balance at the contractual interest rate. Cash interest receipts in excess of that amount are recorded as recoveries to the allowance for loan losses until prior charge-offs have been fully recovered.
Off-Balance Sheet Credit Related Financial Instruments	Off-Balance Sheet Credit Related Financial Instruments In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under standby letters of credit. Such financial instruments are recorded when they are funded.
Premises and Equipment	Premises and Equipment Premises and equipment are stated at cost, less accumulated depreciation. Depreciation is computed on a straight-line basis over the estimated useful lives of the related assets, ranging up to 40 years for premises and 10 years for equipment. Maintenance and repairs are charged to operating expenses as incurred. The asset cost and accumulated depreciation are removed from the accounts for assets sold or retired and any resulting gain or loss is included in the determination of income.
Foreclosed Real Estate	Foreclosed Real Estate Physical possession of residential real estate property collateralizing a residential mortgage loan occurs when legal title is obtained upon completion of foreclosure or when the borrower conveys all interest in the property to satisfy the loan through completion of a deed-in-lieu of foreclosure or through a similar legal agreement. Properties acquired through foreclosure, or by deed-in-lieu of foreclosure, are recorded at their fair value less estimated costs to sell. Fair value is typically determined based on evaluations by third parties. Costs incurred in connection with preparing the foreclosed real estate for disposition are capitalized to the extent that they enhance the overall fair value of the property. Any write-downs on the asset’s fair value less costs to sell at the date of acquisition are charged to the allowance for loan losses. Subsequent write downs and expenses of foreclosed real estate are included as a valuation allowance and recorded in noninterest expense.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill represents the excess cost of an acquisition over the fair value of the net assets acquired. Goodwill is not amortized, but is evaluated annually or when there is a triggering event for impairment. Intangible assets, such as customer lists, are amortized over their useful lives, generally 15 years.
Mortgage Servicing Rights	Mortgage Servicing Rights Originated mortgage servicing rights are recorded at their fair value at the time of transfer of the related loans and are amortized in proportion to, and over the period of, estimated net servicing income or loss. The carrying value of the originated mortgage servicing rights is periodically evaluated for impairment or between annual evaluations under certain circumstances.
Stock-Based Compensation	Stock-Based Compensation Compensation costs related to share-based payment transactions are recognized based on the grant-date fair value of the stock-based compensation issued. Compensation costs are recognized over the period that an employee provides service in exchange for the award. Compensation costs related to the Employee Stock Ownership Plan are dependent upon the average stock price and the shares committed to be released to plan participants through the period in which income is reported.
Retirement Benefits	Retirement Benefits The Company has a non-contributory defined benefit pension plan that covered substantially all employees. On May 14, 2012, the Company informed its employees of its decision to freeze participation and benefit accruals under the plan, primarily to reduce some of the volatility in earnings that can accompany the maintenance of a defined benefit plan. The plan was frozen on June 30, 2012. Compensation earned by employees up to June 30, 2012 is used for purposes of calculating benefits under the plan but there will be no future benefit accruals after this date. Participants as of June 30, 2012 will continue to earn vesting credit with respect to their frozen accrued benefits as they continue to work. Pension expense under these plans is charged to current operations and consists of several components of net pension cost based on various actuarial assumptions regarding future experience under the plans. Gains and losses, prior service costs and credits, and any remaining transition amounts that have not yet been recognized through net periodic benefit cost are recognized in accumulated other comprehensive loss, net of tax effects, until they are amortized as a component of net periodic cost. Plan assets and obligations are measured as of the Company’s statement of condition date. The Company has unfunded deferred compensation and supplemental executive retirement plans for selected current and former employees and officers that provide benefits that cannot be paid from a qualified retirement plan due to Internal Revenue Code restrictions. These plans are nonqualified under the Internal Revenue Code, and assets used to fund benefit payments are not segregated from other assets of the Company, therefore, in general, a participant's or beneficiary's claim to benefits under these plans is as a general creditor. The Bank sponsors an Employee Stock Ownership Plan (“ESOP”) covering substantially all full time employees. The cost of shares issued to the ESOP but not committed to be released to the participants is presented in the consolidated statement of condition as a reduction of shareholders’ equity. ESOP shares are released to the participants on an annual basis in accordance with a predetermined schedule. The Company records ESOP compensation expense based on the shares committed to be released and allocated to the participant’s accounts multiplied by the average share price of the Company’s stock over the period. Dividends related to unallocated shares are recorded as compensation expense.
Derivative Financial Instruments	Derivative Financial Instruments Derivatives are recorded on the statement of condition as assets and liabilities measured at their fair value. The accounting for changes in the fair value of a derivative depends on whether or not the derivative has been designated and qualifies as part of a hedging relationship. The Company acquires derivatives with the intent of designating and qualifying those instruments as part of hedging relationships to other balance sheet assets or liabilities. The specific accounting treatment for increases and decreases in the value of derivatives further depends upon the use of the specific derivatives. There are two primary types of interest rate derivatives that may be employed by the Company: • Fair Value Hedge - As a result of interest rate fluctuations, fixed-rate assets and liabilities will appreciate or depreciate in fair value over the course of their economic lives prior to maturity . When effectively hedged, this appreciation or depreciation will generally be offset by fluctuations in the fair value of derivative instruments that are linked to the hedged assets and liabilities. This strategy is referred to as a fair value hedge. For a fair value hedge, changes in the fair value of the derivative instrument and changes in the fair value of the hedged asset or liability are expected to substantially offset each other and these changes are recognized currently in earnings. • Cash Flow Hedge - Cash flows related to floating rate assets and liabilities will fluctuate with changes in the underlying rate index. When effectively hedged, the increases or decreases in cash flows related to the floating-rate asset or liability will generally be offset by changes in cash flows of the derivative instrumnets designated as a hedge. This strategy is referred to as a cash flow hedge. For a cash flow hedge, changes in the fair value of the derivative instrument, to the extent that it is effective, are recorded in other comprehensive income and subsequently reclassified to earnings as the hedged transaction impacts net income. Any ineffective portion of a cash flow hedge is recognized currently in earnings.
Income Taxes	Income Taxes Provisions for income taxes are based on taxes currently payable or refundable and deferred income taxes on temporary differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements. Deferred tax assets and liabilities are reported in the consolidated financial statements at currently enacted income tax rates applicable to the period in which the deferred tax assets and liabilities are expected to be realized or settled.
Earning Per Share	Earnings Per Share Basic net income per share was calculated using the two-class method by dividing net income (less any dividends on participating securities) by the weighted average number of shares of common stock and participating securities outstanding for the period. Diluted earnings per share may include the additional effect of other securities, if dilutive, in which case the dilutive effect of such securities is calculated by applying either the two-class method or the Treasury Stock method to the assumed exercise or vesting of potentially dilutive common shares. The method yielding the more dilutive result is ultimately reported for the applicable period. Potentially dilutive common stock equivalents primarily consist of employee stock options and restricted stock units. Unallocated common shares held by the ESOP are not included in the weighted average number of common shares outstanding for purposes of calculating earnings per common share until they are committed to be released to plan participants. Note 3 provides more information related to earnings per share.
Segment Reporting	Segment Reporting The Company has evaluated the activities relating to its strategic business units. The controlling interest in the FitzGibbons Agency is dissimilar in nature and management when compared to the Company’s other strategic business units which are judged to be similar in nature and management. The Company has determined that the FitzGibbons Agency is below the reporting threshold in size in accordance with Accounting Standards Codification 280. Accordingly, the Company has determined it has no reportable segments.
Comprehensive Income (Loss)	Comprehensive Income (Loss) Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities are reported as a separate component of the equity section of the statement of condition, such items, along with net income, are components of comprehensive income.
