Summary of Significant Accounti

Summary of Significant Accounting Policies	12 Months Ended

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 the $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. 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. 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. 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 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 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 it has been designated and qualifies as part of a hedging relationship. The specific accounting treatment for increases and decreases in the value of derivatives 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. 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 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: 2019 2018 Unrealized loss for pension and other postretirement obligations $ (3,677 ) $ (4,266 ) Tax effect 960 1,114 Net unrealized loss for pension and other postretirement obligations (2,717 ) (3,152 ) Unrealized loss on available-for-sale securities (293 ) (3,833 ) Tax effect 77 1,001 Net unrealized loss on available-for-sale securities (216 ) (2,832 ) Unrealized loss on securities transferred to held-to-maturity (54 ) (82 ) Tax effect 16 24 Net unrealized loss on securities transferred to held-to-maturity (38 ) (58 ) Accumulated other comprehensive loss $ (2,971 ) $ (6,042 ) Reclassifications Certain amounts in the 2018 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 presentation provides a description of standards that were adopted in 2019 and standards not yet adopted as of December 31, 2019, but could have an impact on the Company's consolidated financial statements upon adoption. Standards Adopted in 2019 Standard : Leases ( ASU 2016-02: Leases [Topic 842] ) Description: The new guidance requires lessees to record a right-of-use asset and a lease liability for all leases with a term greater than 12 months. While the guidance requires all leases to be recognized in the balance sheet, there continues to be a differentiation between finance leases and operating leases for purposes of income statement recognition and cash flow statement presentation. For finance leases, interest on the lease liability and amortization of the right-of-use asset will be recognized separately in the statement of income. Repayments of principal on those lease liabilities will be classified within financing activities and payments of interest on the lease liability will be classified within operating activities in the statement of cash flows. For operating leases, a single lease cost is recognized in the statement of income and allocated over the lease term, generally on a straight-line basis. All cash payments are presented within operating activities in the statement of cash flows. The accounting applied by lessors is largely unchanged from existing GAAP, however, the guidance eliminates the accounting model for leveraged leases for leases that commence after the effective date of the guidance. Required Date of Implementation: January 1, 2019 Effect on Consolidated Financial Statements: The Company occupies certain banking offices and uses certain equipment under noncancelable operating lease agreements which were not reflected in its consolidated balance sheet at December 31, 2018. Upon adoption of this ASU on January 1, 2019, the Company recorded an asset of $2.5 million and a corresponding liability of $2.7 million, as a result of recognizing right-of-use assets and lease liabilities on its consolidated statement of financial condition. The Company elected to adopt the transition relief under Topic 842, Leases, using the modified retrospective transition method recognizing a cumulative effect adjustment to the opening balance of retained earnings of $239,000. The periods presented prior to January 1, 2019 continue to be in accordance with ASC 840. Under the new lease standard, disclosures are required to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. T he Company uses its incremental borrowing rate based on the information available in determining the present value of lease payments. We elected all applicable practical expedients and implemented internal controls and key system functionality to enable the preparation of financial information on adoption. The Company owns certain properties that it leases to unaffiliated third parties at market rates. Lease rental income was $34,000 and $30,000 for the twelve months ended March 31, 2019 and 2018, respectively. All lease agreements are accounted for as operating leases. The Company has no unamortized initial direct costs related to the establishment of these lease agreements at January 1, 2019. ____ Standard: Premium Amortization on Purchased Callable Debt Securities ( ASU 2017-08: Receivables—Nonrefundable Fees and Other Costs [Subtopic 310-20]: Premium Amortization on Purchased Callable Debt Securities ) Description: The amended guidance requires the premium on callable debt securities to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. Required Date of Implementation: January 1, 2019 Effect on Consolidated Financial Statements : The Company has consistently employed accounting methodologies with respect to securities with purchased premiums that are consistent with the guidance provided in this Update. Accordingly, the adoption of this guidance had no material impact on the Company’s consolidated financial statements. ____ Standard: Improvements to Nonemployee Share-Based Payment Accounting ( ASU 2018-07: Compensation - Stock Compensation [Topic 718]) Description: Consistent with the accounting requirement for employee share-based payment awards, under the new guidance, nonemployee share-based payment awards within the scope of Topic 718 are measured on the grant date at the grant-date fair value of the equity instruments that an entity is obligated to issue when the good has been delivered or the service has been rendered and any other conditions necessary to earn the right to benefit from the instruments have been satisfied. The amendments in this ASU affect all entities that enter into share-based payment transactions for acquiring goods and services from nonemployees. Required Date of Implementation: January 1, 2019 Effect on Consolidated Financial Statements: The amendments should be applied using a prospective transition method. The Company is not currently party to any nonemployee share-based payment awards whereby the participant is obligated to any specific performance requirement other than to remain in the service of the Company through a specified vesting date, or schedule of vesting dates. Accordingly, the adoption of this ASU had no material impact on the Company’s consolidated financial statements. Standards Not Yet Adopted as of December 31, 2019 Standard: Measurement of Credit Losses on Financial Instruments ( ASU 2016-13: Financial Instruments—Credit Losses [Topic 326]: Measurement of Credit Losses on Financial Instruments ) Description: 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. Required Date of Implementation: January 1, 2023 (early adoption permitted as of January 1, 2019). Effect on Consolidated Financial Statements: 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: Transition Relief for the Implementation of ASU-2016-13 ( ASU 2019-5: Financial Instruments—Credit Losses [Topic 326]: Targeted Transition Relief ) Description: 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, with an option to irrevocably elect the fair value option in Subtopic 825-10, Financial Instruments—Overall, applied on an instrument-by-instrument basis for eligible instruments, upon adoption of Topic 326. The fair value option election does not apply to held-to-maturity debt securities. An entity that elects the fair value option should subsequently apply the guidance in Subtopics 820-10, Fair Value Measurement—Overall, and 825-10. General guidance for the use of the fair value option is contained in Subtopic 825-10. The irrevocable election of the fair value option must be applied on an instrument-by-instrument basis for eligible instruments, whose characteristics are within the scope of Subtopic 326-20. Upon adoption of Topic 326, for items measured at fair value in accordance with paragraph 326-10-65-1(i), the difference between the carrying amount and the fair value shall be recorded by means of a cumulative-effect adjustment to the opening retained earnings balance as of the beginning of the first reporting period that an entity has adopted ASU 2016-13. Those differences may include, but are not limited to: (1) unamortized deferred costs, fees, premiums, and discounts (2) valuation allowances (for example, allowance for loan losses), or (3) accrued interest. Required Date of Implementation: See comments above related to ASU 2016-13. Effect on Consolidated Financial Statements: See comments above related to ASU 2016-13. _____ Standard: Simplifying the Test for Goodwill Impairment ( ASU 2017-04: Intangibles—Goodwill and Other [Topic 350]: Simplifying the Test for Goodwill Impairment ) Description: Current guidance requires a two-step approach to determining if recorded goodwill is impaired. In Step 1, reporting entities must first evaluate whether or not the carrying value of a reporting unit is greater than its fair value. In Step 2, if a reporting unit’s carrying value is greater than its fair value, then the entity should calculate the implied fair value of goodwill. If the carrying value of goodwill is more than the implied fair value, an impairment charge for the difference must be recorded. The amended guidance eliminates Step 2 from the goodwill impairment test. Therefore, under the new guidance, if the carrying value of a reporting unit is greater than its fair value, a goodwill impairment charge will be recorded for the difference (up to the carrying value of the recorded goodwill). Required Date of Implementation: January 1, 2020 (early adoption permitted). Effect on Consolidated Financial Statements: The amendments should be applied using a prospective transition method. The Company does not expect the guidance will have a material impact on its consolidated financial statements, unless at some point in the future one of its reporting units were to fail Step 1 of the goodwill impairment test. ____ Standard : Fair Value Measurement ( ASU 2018-13: Fair Value Measurement [Topic 820]: Disclosure Framework Changes to the Disclosure Requirements for Fair Value Measurement Description: 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. Required Date of Implementation: The amendments in this ASU are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted upon issuance of this Update. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the additional disclosures until their effective date. Effect on Consolidated Financial Statements: The Company does not expect the new guidance will have a material impact to its consolidated statements of condition or income. ____ Standard : 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) Description: 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. 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. Required Date of Implementation: 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. Effect on Consolidated Financial Statements: The Company does not expect the new guidance will have a material impact to its consolidated statements of condition or income. ____ Standard: Leases ( ASU 2019-01: Leases [Topic 842] Codification Improvements) Description: On February 25, 2016, the FASB issued Accounting Standards ASU No. 2016-02, Leases [Topic 842], to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing essential information about leasing transactions. ASU 2019-01 addresses three Issues: (1) Determining the fair value of the underlying asset by lessors that are not manufacturers or dealers; (2) Presentation on the statement of cash flows for sales-type and direct financing leases; and (3) Transition disclosures related to Topic 250, Accounting Changes and Error Corrections . The amendments in this ASU address Issue 1, described above, and reinstate the exception in Topic 842 for lessors that are not manufacturers or dealers (generally financial institutions and captive finance companies). Specifically, those lessors will use their cost, reflecting any volume or trade discounts that may apply, as the fair value of the underlying asset. However, if significant time lapses between the acquisition of the underlying asset and lease commencement, those lessors will be required to apply the definition of fair value (exit price) in Topic 820. Topic 840 does not provide guidance on how cash received from leases by lessors from sales-type and direct financing leases should be presented in the cash flow statement. The amendments in this ASU address Issue 2, described above, as to the concerns of lessors within the scope of Topic 942 about where “principal payments received under leases” should be presented. Specifically, lessors that are depository and lending institutions within the scope of Topic 942 will present all “principal payments received under leases” within investing activities in the Statement of Cash Flows. Required Date of Implementation : The amendments in this ASU amend Topic 842. The effective date of those amendments for public business entities, such as the Company, is for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Effect on Consolidated Financial Statements: The Company does not expect that the new guidance will have a material impact to its consolidated statements of condition or income. ____ Standard : 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) Description: Since 2016, the FASB has issued the following Updates related to financial instruments: 1. Accounting Standards Update No. 2016-01, Financial Instruments— Overall [Subtopic 825-10]: Recognition and Measurement of Financial Assets and Financial Liabilities 2. Accounting Standards Update No. 2016-13, Financial Instruments— Credit Losses [Topic 326]: Measurement of Credit Losses on Financial Instruments; 3. Accounting Standards Update No. 2017-12, Derivatives and Hedging [Topic 815]: Targeted Improvements to Accounting for Hedging Activities. The FASB has an ongoing project on its agenda for improving the Codification or correcting its unintended application. The items addressed in that project generally are not expected to have a significant effect on current accounting practice or to create a significant administrative cost for most entities. The amendments in this ASU are similar to those items and are summarized below. For Codification Improvements specific to ASU 2016-01, the following topics were 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 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 The ASU also covered a number of issues that related 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 Required Dates of Implementation : 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. Effect on Consolidated Financial Statements: The Company does not expect that the new guidance will have a material impact to its consolidated statements of condition or income. ____ Standard : 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 ) Description: 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. Required Date of Implementation: 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. Effect on Consolidated Financial Statements: The amendments in this Update should be applied prospectively. The Company does not expect the new guidance will have a material impact to its consolidated statements of condition or income. ____ Standard: Income Taxes (ASU 2019-12- Simplifying the Accounting for Income Taxes) Description: The FASB Board is issuing this Update as part of its initiative to reduce complexity in accounting standards (the Simplification Initiative). The objective of the Simplification Initiative is to identify, evaluate, and improve areas of generally accepted accounting principles (GAAP) for which cost and complexity can be reduced while maintaining or improving the usefulness of the information provided to users of financial statements. The specific areas of potential simplification in this Update were submitted by stakeholders as part of the Simplification Initiative. The amendments in this Update simplify the accounting for income taxes by removing the following exceptions: 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 requirement to recognize a deferred tax liability for equity method investments when a foreign subsidiary becomes an equity method investment 3. Exception to the ability not to recognize a deferred tax liability for a foreign subsidiary when a foreign equity method investment becomes a subsidiary 4. 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. Required Date of Implementation: 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. Effect on Consolidated Financial Statements : 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 : Financial Instruments—Credit Losses (ASU 2019-11- Codification Improvements to Topic 326) Description: On June 16, 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which introduced an expected credit loss model for the impairment of financial assets measured at amortized cost basis. That model replaces the probable, incurred loss model for those assets. Through the amendments in that Update, the Board added Topic 326, Financial Instruments—Credit Losses, and made several consequential amendments to the Codification. The Board has an ongoing project on its agenda for improving the Codification or correcting its unintended application. The items addressed in that project generally are not expected to have a significant effect on current accounting practice or create a significant administrative cost for most entities. The amendments in this Update are similar to those items. However, the Board decided to issue a separate Update for improvements to the amendments in Update 2016-13 to increase stakeholder awareness of those amendments and to expedite the improvement process. The amendments include items brought to the Board's attention by stakeholders. 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 esti

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) 37,700 shares of the Company’s common stock, par value $0.01 per share, at a purchase price of $14.25 per share; (ii) 1,155,283 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 for gross proceeds of approximately $17.0 million. 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 for the year ended December 31, 2019, 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. Basic earnings per share for the year ended December 31, 2018 was calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Net income available to common shareholders is net income to Pathfinder Bancorp, Inc. less the total of preferred dividends declared, if any. Diluted earnings per share include the potential dilutive effect that could occur upon the assumed exercise of issued stock options using the Treasury Stock method. 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 -0- for the years ended 2019 and 2018. The following table sets forth the calculation of basic and diluted earnings per share.

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 other securities within the portfolio as of December 31, 2019 represents OTTI. There were a total of 20 securities classified as available-for-sale and 3 securities classified as held-to-maturity that were in an unrealized loss position for 12 months or longer at December 31, 2019. 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 changes in general interest rates that occurred since the securities were acquired or due to changes in certain assumptions related to the securities’ such as the timing of projected prepayment activity. Of the 23 securities in an unrealized loss position for 12 months or more at December 31, 2019, 15 securities, representing 69.8% of the amortized cost of the total securities in an unrealized loss position for 12 months or more, 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 primarily to changes in interest rates subsequent to the acquisition of the individual securities. In addition to these securities, the Company held the following issuances that were in an unrealized loss position for 12 or more months at December 31, 2019: One privately-issued asset-backed security, categorized as available-for-sale, with an amortized historical cost of $606,000 and a fair value of $594,000 (unrealized loss of $12,000, or 2.06%). 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. Five privately-issued collateralized mortgage obligation securities, categorized as available-for-sale, with an aggregate amortized historical cost of $3.9 million and an aggregate fair value of $3.9 million (aggregate unrealized loss of $36,000, or 0.92%). These securities were not rated at the time of their issuances by any NRSRO but each security remains significantly collateralized through subordination. Therefore, no credit-related OTTI is deemed to be present. Two privately-issued collateralized mortgage obligation securities, categorized as held-to-maturity, with aggregate The Company does not intend to sell any of the securities in an unrealized loss position for 12 or months 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 $103.0 million and $35.6 million, respectively on sales and redemptions of securities for the years ended December 31 resulted in gross realized gains (losses) detailed below (In thousands) 2019 2018 Realized gains on investments $ 707 $ 242 Realized losses on investments (378 ) (424 ) $ 329 $ (182 ) As of December 31, 2019 and December 31, 2018, securities with a fair value of $92.4 million and $69.8 million, respectively, were pledged to collateralize certain municipal deposit relationships. As of the same dates, securities with a fair value of $21.3 million and $19.5 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.

As of December 31, 2019 and December 31, 2018, residential mortgage loans with a carrying value of $136.9 million and Loan Origination / Risk Management The Company has lending policies and procedures in place that are designed to maximize loan income within an acceptable level of risk. 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 70% of the portfolio in 2019, similar to the composition in 2018, where such loans represented 77% 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, 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 As of December 31, 2018 Special (In thousands) Pass Mention Substandard Doubtful Total Residential mortgage loans: 1-4 family first-lien residential mortgages $ 228,563 $ 999 $ 1,190 $ 1,771 $ 232,523 Construction 7,121 - - - 7,121 Total residential mortgage loans 235,684 999 1,190 1,771 239,644 Commercial loans: Real estate 201,997 8,299 1,947 71 212,314 Lines of credit 42,489 1,491 233 22 44,235 Other commercial and industrial 59,344 3,268 612 135 63,359 Tax exempt loans 9,320 - - - 9,320 Total commercial loans 313,150 13,058 2,792 228 329,228 Consumer loans: Home equity and junior liens 25,706 144 173 86 26,109 Other consumer 25,294 95 35 - 25,424 Total consumer loans 51,000 239 208 86 51,533 Total loans $ 599,834 $ 14,296 $ 4,190 $ 2,085 $ 620,405 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. An age analysis of past due loans, not including net deferred loan costs, segregated by portfolio segment and class of loans, for the years ended December 31, are detailed in the following tables: As of December 31, 2019 30-59 Days 60-89 Days 90 Days Past Due Past Due and Total Total Loans (In thousands) and Accruing and Accruing Over Past Due Current Receivable Residential mortgage loans: 1-4 family first-lien residential mortgages $ 947 $ 744 $ 1,613 $ 3,304 $ 206,255 $ 209,559 Construction - - - - 3,963 3,963 Loans held-for-sale - - - - 35,790 35,790 Total residential mortgage loans 947 744 1,613 3,304 246,008 249,312 Commercial loans: Real estate 953 100 2,271 3,324 250,933 254,257 Lines of credit 4,464 25 68 4,557 54,060 58,617 Other commercial and industrial 2,747 315 591 3,653 78,439 82,092 Tax exempt loans - - - - 8,067 8,067 Total commercial loans 8,164 440 2,930 11,534 391,499 403,033 Consumer loans: Home equity and junior liens 315 130 480 925 45,464 46,389 Other consumer 335 50 151 536 82,071 82,607 Total consumer loans 650 180 631 1,461 127,535 128,996 Total loans $ 9,761 $ 1,364 $ 5,174 $ 16,299 $ 765,042 $ 781,341 As of December 31, 2018 30-59 Days 60-89 Days 90 Days Past Due Past Due and Total Total Loans (In thousands) and Accruing and Accruing Over Past Due Current Receivable Residential mortgage loans: 1-4 family first-lien residential mortgages $ 1,507 $ 505 $ 1,176 $ 3,188 $ 229,335 $ 232,523 Construction - - - - 7,121 7,121 Total residential mortgage loans 1,507 505 1,176 3,188 236,456 239,644 Commercial loans: Real estate 4,261 364 323 4,948 207,366 212,314 Lines of credit 1,033 111 22 1,166 43,069 44,235 Other commercial and industrial 814 44 387 1,245 62,114 63,359 Tax exempt loans - - - - 9,320 9,320 Total commercial loans 6,108 519 732 7,359 321,869 329,228 Consumer loans: Home equity and junior liens 247 6 35 288 25,821 26,109 Other consumer 226 65 107 398 25,026 25,424 Total consumer loans 473 71 142 686 50,847 51,533 Total loans $ 8,088 $ 1,095 $ 2,050 $ 11,233 $ 609,172 $ 620,405 Year-end nonaccrual loans, segregated by class of loan, were as follows: December 31, December 31, (In thousands) 2019 2018 Residential mortgage loans: 1-4 family first-lien residential mortgages $ 1,613 $ 1,176 Total residential mortgage loans 1,613 1,176 Commercial loans: Real estate 2,343 415 Lines of credit 68 28 Other commercial and industrial 591 387 Total commercial loans 3,002 830 Consumer loans: Home equity and junior liens 480 35 Other consumer 151 107 Total consumer loans 631 142 Total nonaccrual loans $ 5,246 $ 2,148 There were no loans past due ninety days or more and still accruing interest at December 31, 2019 or 2018. 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, 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 twelve months 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 table below details loans that have been modified as TDRs for the year ended December 31, 2018. For the year ended December 31, 2018 (In thousands) Number of loans Pre-modification outstanding recorded investment Post-modification outstanding recorded investment Additional provision for loan losses Other commercial and industrial loans 1 $ 300 $ 300 $ - Commercial real estate loans 1 $ 123 $ 137 $ 14 The TDRs individually evaluated for impairment have been classified as TDRs due to economic concessions granted, which consisted of additional funds advanced without associated increases in collateral and/or an extended maturity date that will result in a delay in payment from the original contractual maturity. The Company was required to increase the specific reserves against the commercial real estate loan individually reviewed for impairment by $14,000, which was a component of the provision of loan losses in the fourth quarter of 2018. 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, 2019, which had subsequently defaulted during the year ended December 31, 2019. The Company had no loans that had been modified as TDRs during the twelve months prior to December 31, 2018, which had subsequently defaulted during the year ended December 31, 2018. 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]
ALLOWANCE FOR LOAN LOSSES	Changes in the allowance for loan losses for the years ended December 31, 2019 and 2018 and information pertaining to the allocation of the allowance for loan losses and balances of the allowance for loan losses and loans receivable based on individual and collective impairment evaluation by loan portfolio class at the indicated dates are summarized in the tables below. An allocation of a portion of the allowance to a given portfolio class does not limit the Company’s ability to absorb losses in another portfolio class.

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. The allocation of the allowance for loan losses summarized on the basis of the Company’s calculation methodology was as follows: 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 December 31, 2018 1-4 family first-lien Other residential Commercial Commercial commercial (In thousands) mortgage Construction real estate lines of credit and industrial Specifically reserved $ 108 $ - $ 100 $ 28 $ 255 Historical loss rate 87 - 85 20 24 Qualitative factors 571 - 3,393 682 1,006 Total $ 766 $ - $ 3,578 $ 730 $ 1,285 Home equity Other Tax exempt and junior liens consumer Unallocated Total Specifically reserved $ - $ 140 $ - $ - $ 631 Historical loss rate - 15 155 - 386 Qualitative factors 1 254 230 - 6,137 Other - - - 152 152 Total $ 1 $ 409 $ 385 $ 152 $ 7,306

GOODWILL AND INTANGIBLE ASSETS	NOTE 10: 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 for impairment or between annual evaluations in certain circumstances. Management performs an annual assessment of the Company’s goodwill to determine whether or not any impairment of the carrying value may exist. Of the $4.5 million of goodwill carried on the Company’s books as of December 31, 2019, $3.8 million of this amount was due to prior periods acquisitions of bank branches and $696,000 was due to the 2013 acquisition of the FitzGibbons Agency by Pathfinder Risk Management Company, Inc. and the 2015 acquisition of the Huntington Agency. The Company is permitted to assess qualitative factors to determine if it is more likely than not that the fair value of the reporting unit is less than the carrying value. Based on the results of the assessment, management has determined that the carrying value of goodwill in the amount of $4.5 million is not impaired as of December 31, 2019. The identifiable intangible asset of $149,000 as of December 31, 2019 was due to the acquisition of the FitzGibbons and Huntington Agencies and represents the amortized carrying amount of the customer lists intangible.

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 $213,000 and $199,000 in interest expense related to this issuance in 2019 and 2018, 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, 2019 and 2018. 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 with an unrelated third party that is scheduled to mature on October 1, 2025. The Company has the right to prepay the Subordinated Loan at any time after October 15, 2020 without penalty. The annual interest rate charged to the Company will be 6.25% through the maturity date of the subordinated loan. The Subordinated Loan is senior in the Company’s credit repayment hierarchy only to the Company’s common equity 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 will be amortized over the life of the Subordinated Loan through its first call date using the effective interest method. The effective cost of funds related to this transaction is 6.44% calculated under this method.

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) 2019 2018 2019 2018 Change in benefit obligations: Benefit obligations at beginning of year $ 10,095 $ 10,469 $ 454 $ 481 Service cost - - - - Interest cost 494 473 22 21 Plan participants' contribution - - 8 9 Actuarial loss (gain) 1,558 (581 ) (27 ) (16 ) Benefits paid (255 ) (266 ) (43 ) (41 ) Benefit obligations at end of year 11,892 10,095 414 454 Change in plan assets: Fair value of plan assets at beginning of year 14,522 14,956 - - Actual return on plan assets 2,718 (993 ) - - Benefits paid (255 ) (266 ) (43 ) (41 ) Plan participants' contribution - - 8 9 Employer contributions - 825 35 32 Fair value of plan assets at end of year 16,985 14,522 - - Funded (unfunded) status - asset (liability) $ 5,093 $ 4,427 $ (414 ) $ (454 ) 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) 2019 2018 2019 2018 Net loss $ 3,557 $ 4,112 $ 117 $ 151 Tax Effect 929 1,074 31 40 $ 2,628 $ 3,038 $ 86 $ 111 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, 2019 and December 31, 2018. 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 3.97% at December 31, 2019. 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 3.97% at December 31, 2019. 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 $11.9 million and $10.1 million at December 31, 2019 and 2018, respectively. The postretirement plan had an accumulated benefit obligation of $414,000 and $454,000 at December 31, 2019 and 2018, respectively. The significant assumptions used in determining the benefit obligations as of December 31, are as follows: Pension Benefits Postretirement Benefits 2019 2018 2019 2018 Weighted average discount rate 3.97 % 4.97 % 3.97 % 4.97 % 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 2020, gradually decreasing to 4.20% in 2023 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) 2019 2018 2019 2018 Service cost $ - $ - $ - $ - Interest cost 494 473 22 21 Expected return on plan assets (934 ) (1,037 ) - - Amortization of transition obligation - - - - Amortization of net losses 328 164 12 13 Amortization of unrecognized past service liability - - (5 ) (5 ) Net periodic benefit plan (benefit) cost $ (112 ) $ (400 ) $ 29 $ 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 2019 2018 2019 2018 Weighted average discount rate 3.97 % 4.97 % 3.97 % 4.97 % Expected long term rate of return on plan assets 6.50 % 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 6.5% expected long-term rate of return in 2019 and a 6.5% expected long-term rate of return in 2020 reflecting current economic conditions and expected rates of return. Based on the $17.0 million fair value of plan assets at December 31, 2019, each 50 basis point decrease in the expected long-term rate of return would reduce after tax net income at 2020 expected marginal tax rate of 21.0% by approximately $67,000. The estimated net actuarial loss that will be amortized from accumulated other comprehensive loss into net periodic benefit plan income during 2020 is $228,000. The estimated amortization of the unrecognized transition obligation and actuarial loss for the postretirement health plan in 2020 is $10,000. The expected net periodic benefit plan benefit for 2020 is estimated to be $379,000 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 risk 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 SERP benefits certain key senior executives of the Bank who are selected by the Board to participate, including our Named Executive Officers. 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, 2019 and 2018, other liabilities included $836,000 and $745,000, 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, 2019 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 $369,000 $30,000 116,102

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. 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. Commencing on January 1, 2018, the Company changed its elected interest income subtraction methodology under which its New York income tax expense is calculated. This change in the Company’s interest income subtraction election was adopted following changes to the New York State Tax Code enacted in 2015 and resulted in a reduction of the Company’s effective income tax rate in New York beginning in 2018. It is anticipated that the Company’s New York effective income tax rate will remain substantially at 0.0% in future periods under current law. In the first quarter of 2019, the Company established, through a charge to earnings, a valuation allowance in the amount of $136,000 in order to establish a reserve against deferred tax assets related to New York income taxes. The establishment of this reserve increased the Company’s effective tax rate by 2.5% in 2019. This reserve was established as the items giving rise to the deferred tax assets related to New York taxes are unlikely to further reduce the Company’s income taxes in the future following the adoption of the new subtraction methodology. There were no valuation allowances against deferred tax assets at December 31, 2018. In 2019, the Company’s effective tax rate was 21.4%, as compared to 11.9% in 2018. A reconciliation of the federal statutory income tax rate to the effective income tax rate for the years ended December 31, is as follows: 2019 2018 Federal statutory income tax rate 21.0 % 21.0 % State tax, net of federal benefit (1.5 ) (3.7 ) Tax-exempt interest income (0.9 ) (4.3 ) Increase in value of bank owned life insurance less premiums paid (1.7 ) (1.9 ) Change in valuation allowance 2.5 - Other 1.9 0.9 Effective income tax rate - Pathfinder Bancorp, Inc. 21.3 % 12.0 % Minority interest 0.1 (0.1 ) Effective income tax rate 21.4 % 11.9 %

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, 2019 and 2018, the following financial instruments were outstanding whose contract amounts represent credit risk: Contract Amount (In thousands) 2019 2018 Commitments to grant loans $ 47,606 $ 37,354 Unfunded commitments under lines of credit 81,038 74,284 Unfunded commitments related to construction loans in progress 3,214 5,058 Standby letters of credit 2,082 2,007 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, 2019 with variable interest rates and fixed interest rates amounted to approximately $122.8 million and $11.1 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.

Dividends and Restrictions

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 $14.1 million as of December 31, 2019. 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, 2019, December 31, 2018 or December 31, 2017. 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, 2019, 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 as of January 1, 2019. At December 31, 2019, the Bank exceeded all regulatory required minimum capital ratios, including the capital buffer requirements.

Regulatory Matters

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, 2019, 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 as of January 1, 2019. At December 31, 2019, 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, 2019 and 2018 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, 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 % As of December 31, 2018: Total Core Capital (to Risk-Weighted Assets) $ 83,177 13.69 % $ 48,593 8.00 % $ 60,741 10.00 % $ 63,778 10.50 % Tier 1 Capital (to Risk-Weighted Assets) $ 75,871 12.49 % $ 36,445 6.00 % $ 48,593 8.00 % $ 51,630 8.50 % Tier 1 Common Equity (to Risk-Weighted Assets) $ 75,871 12.49 % $ 27,334 4.50 % $ 39,482 6.50 % $ 42,519 7.00 % Tier 1 Capital (to Assets) $ 75,871 8.31 % $ 36,522 4.00 % $ 45,652 5.00 % $ 45,652 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 .

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, 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, 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) $ 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, 2019, the amortized cost of the basis of the closed portfolio used in the hedging relationship was $19.3 million, the cumulative basis adjustment associated with the hedging relationship was $75,000, and the amount of the designated hedged item was $9.2 million. At December 31, 2019, the fair value of the derivative resulted in a net liability position of $92,000 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’s agreement with its interest rate swap counterparty contains a provision whereby if either party defaults on any of its indebtedness, then that party could also be declared in default on its derivative obligations. The agreement with the Company’s derivative counterparty also includes certain other provisions that if not met, could result in the Company or the counterparty being declared in default. If either the Company or the counterparty were to be declared in default, the other party to the agreement can terminate the derivative position and require settlement of all obligations as specifically outlined within the terms of the agreement.

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 two corporate investment securities with an aggregate amortized historical cost of $4.8 million and an aggregate fair market value of $4.9 million as of December 31, 2019. These securities have valuations that are determined using published net asset values (NAV) derived by analyses of the securities’ underlying assets. These securities are 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. Interest rate swap derivative: The fair value of the interest rate swap derivative is calculated based on a discounted cash flow model. All future floating cash flows are projected and both floating and fixed cash flows are discounted to the valuation date. The curve utilized for discounting and projecting 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. Foreclosed real estate: Fair values for foreclosed real estate are initially recorded based on market value evaluations by third parties, less costs to sell (“initial cost basis”). Any write-downs required when the related loan receivable is exchanged for the underlying real estate collateral at the time of transfer to foreclosed real estate are charged to the allowance for loan losses. Values are derived from appraisals, similar to impaired loans, of underlying collateral or discounted cash flow analysis. Subsequent to foreclosure, valuations are updated periodically and assets are marked to current fair value, not to exceed the initial cost basis. In the determination of fair value subsequent to foreclosure, management also considers other factors or recent developments, such as, changes in absorption rates and market conditions from the time of valuation and anticipated sales values considering management’s plans for disposition. Either change could result in adjustment to lower the property value estimates indicated in the appraisals. These measurements are classified as Level 3 within the fair value hierarchy. 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, 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 Interest rate swap derivative $ - $ (92 ) $ - $ (92 ) December 31, 2018 Total Fair (In thousands) Level 1 Level 2 Level 3 Value Available-for-Sale Portfolio Debt investment securities: US Treasury, agencies and GSEs $ - $ 17,031 $ - $ 17,031 State and political subdivisions - 23,065 - 23,065 Corporate - 12,141 - 12,141 Asset backed securities - 18,119 - 18,119 Residential mortgage-backed - US agency - 31,666 - 31,666 Collateralized mortgage obligations - US agency - 46,441 - 46,441 Collateralized mortgage obligations - Private label - 23,936 - 23,936 Total - 172,399 - 172,399 Corporate measured at NAV - - - 5,059 Total available-for-sale securities $ - $ 172,399 $ - $ 177,458 Marketable equity securities $ - $ 453 $ - $ 453 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, 2019 Total Fair (In thousands) Level 1 Level 2 Level 3 Value Impaired loans $ - $ - $ 3,105 $ 3,105 Foreclosed real estate $ - $ - $ - $ - December 31, 2018 Total Fair (In thousands) Level 1 Level 2 Level 3 Value Impaired loans $ - $ - $ 1,098 $ 1,098 Foreclosed real estate $ - $ - $ 1,173 $ 1,173 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.

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. Interest earning time deposits – The carrying amounts of these assets approximate their fair value and are classified as Level 1. Investment securities – The fair values of securities available-for-sale and held-to-maturity are obtained from an independent third party and are based on quoted prices on nationally recognized exchange 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 two corporate investment securities with an aggregate amortized historical cost of $4.8 million and an aggregate fair market value of $4.9 million as of December 31, 2019. These securities have valuations that are determined using published net asset values (NAV) derived by analyses of the securities’ underlying assets.

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. 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. Interest rate swap derivative: The fair value of the interest rate swap derivative is calculated based on a discounted cash flow model. All future floating cash flows are projected and both floating and fixed cash flows are discounted to the valuation date. The curve utilized for discounting and projecting is built by obtaining publicly available third party market quotes for various swap maturity terms.

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 4,362,328 and 4,709,238 shares outstanding at December 31, 2018 and December 31, 2019, 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.

Subsequent Events [Abstract]
Subsequent Events	NOTE 29: SUBSEQUENT EVENTS The outbreak of Coronavirus Disease 2019 (“COVID-19”) could adversely impact a broad range of industries in which the Company’s customers operate and impair their ability to fulfill their financial obligations to the Company. The World Health Organization has declared Covid-19 to be a global pandemic indicating that almost all public commerce and related business activities must be, to varying degrees, curtailed with the goal of decreasing the rate of new infections. The spread of the outbreak will likely cause significant disruptions in the U.S. economy and is highly likely to disrupt banking and other financial activity in the areas in which the Company operates and could also potentially create widespread business continuity issues for the Company. The Company’s business is dependent upon the willingness and ability of its employees and customers to conduct banking and other financial transactions. If the global response to contain COVID-19 escalates or is unsuccessful, the Company could experience a material adverse effect on its business, financial condition, results of operations and cash flows. The Company’s management routinely evaluates the overall characteristics of its loan portfolio. Such evaluations may include analyses of certain loans for potential sales to unaffiliated third parties. Loan sales may be made in response to a variety of factors such as changes in market conditions or changes in the level of certain loan-type concentrations. Such sales, when executed, would typically be made in order to improve certain characteristics within the overall loan portfolio, viewed individually or in combination, related to factors such as cash flow, liquidity, duration or potential interest rate risk. On January 28, 2020, the Company completed the sale of 267 residential mortgage loans, on a servicing-retained basis, that were categorized as loans held-for-sale as of December 31, 2019. The loans had been previously held in portfolio from two to five years. The loans were acquired by FNMA in a transaction arranged and managed by an independent third party. The sold loans had an aggregate unpaid principal balance of $35.7 million and a weighted average coupon of 4.08%. Loan sales of this specific type are executed with the intention of reducing the overall duration of the loan portfolio and the Company’s potential exposure to the effects of rising interest rates as well as to provide liquidity for other lending activities. As a result of the sale, the Company recognized a pre-tax gain of $370,000 on the sale and capitalized an additional $289,000 in retained mortgage servicing rights. In total, therefore, pretax revenue was increased by $659,000 in January 2020 as a result of this transaction. The proceeds of the sale will be used on an interim basis to improve overall balance sheet liquidity by reducing the Company’s aggregate level of borrowed funds and/or brokered certificates of deposit in the remainder of the first quarter of 2020. Ultimately, it is expected that the proceeds of the transaction will be used to fund growth in the Company’s commercial and commercial real estate loan portfolios. On March 23, 2020, the Company announced that its Board of Directors had declared a cash dividend of $0.06 per common and preferred share, and a cash dividend of $0.06 per notional share for the issued common stock Warrant. The dividend will be payable on May 8, 2020 to shareholders of record on April 16, 2020.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended

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 the $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.
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. 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. 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 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 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 it has been designated and qualifies as part of a hedging relationship. The specific accounting treatment for increases and decreases in the value of derivatives 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. 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 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. 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: 2019 2018 Unrealized loss for pension and other postretirement obligations $ (3,677 ) $ (4,266 ) Tax effect 960 1,114 Net unrealized loss for pension and other postretirement obligations (2,717 ) (3,152 ) Unrealized loss on available-for-sale securities (293 ) (3,833 ) Tax effect 77 1,001 Net unrealized loss on available-for-sale securities (216 ) (2,832 ) Unrealized loss on securities transferred to held-to-maturity (54 ) (82 ) Tax effect 16 24 Net unrealized loss on securities transferred to held-to-maturity (38 ) (58 ) Accumulated other comprehensive loss $ (2,971 ) $ (6,042 )
Reclassifications	Reclassifications Certain amounts in the 2018 consolidated financial statements have been reclassified to conform to the current year presentation. These reclassifications had no effect on net income as previously reported.
