Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	Note 1: Basis of Presentation The accompanying unaudited consolidated financial statements of Pathfinder Bancorp, Inc., (the “Company”), Pathfinder Bank (the “Bank”) and its other wholly owned subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information, the instructions for Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes necessary for a complete presentation of consolidated financial condition, results of operations and cash flows in conformity with generally accepted accounting principles. In the opinion of management, all adjustments, consisting of normal recurring accruals considered necessary for a fair presentation, have been included. Certain amounts in the 2018 consolidated financial statements may have been reclassified to conform to the current period presentation. These reclassifications had no effect on net income or comprehensive income as previously reported. Operating results for the three and nine months ended September 30, 2019 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2019 or any other interim period. The Company's consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States and follow practices within the banking industry. Application of these principles requires management to make estimates, assumptions, and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. These estimates, assumptions, and judgments are based on information available as of the date of the financial statements; accordingly, as this information changes, the financial statements could reflect different estimates, assumptions, and judgments. Certain accounting policies inherently have a greater reliance on the use of estimates, assumptions, and judgments and as such have a greater possibility of producing results that could be materially different than originally reported. Estimates, assumptions, and judgments are necessary when assets and liabilities are required to be recorded at fair value or when an asset or liability needs to be recorded contingent upon a future event. Carrying assets and liabilities at fair value inherently results in more financial statement volatility. The fair values and information used to record valuation adjustments for certain assets and liabilities are based on quoted market prices or are provided by unaffiliated third-party sources, when available. When third party information is not available, valuation adjustments are estimated in good faith by management. Although the Company owns, through its subsidiary Pathfinder Risk Management Company, Inc., 51% of the membership interest in FitzGibbons Agency, LLC (“Agency”), the Company is required to consolidate 100% of the Agency 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.

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 generally accepted accounting principles (“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 the accounting Standards Not Yet Adopted as of September 30, 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 Company expects that the new guidance will result in an increase in its allowance for credit losses as a result of considering credit losses over the expected life of its loan and debt securities portfolios. Increases in the level 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. 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. _____ 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.

Earnings Per Share [Abstract]
Earnings per Common Share	Note 3: Earnings per Common 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 (the “Private Placement”) 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 three and nine months ended September 30, 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 three and nine months ended September 30, 2018 were 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 three and nine months ended September 30, 2019 and were -0- for the three and nine months ended September 30, 2018. The following table sets forth the calculation of basic and diluted earnings per share.

The most significant market and environmental factors include, but are not limited to (1) the general level of interest rates, (2) the relationship between shorter-term interest rates and longer-term interest rates (referred to as the “slope” of the interest rate yield curve), (3) general bond market liquidity, (4) the recent and expected near-term volume of new issuances of similar debt securities, and (5) changes in the market values of individual loan collateral underlying mortgage-backed debt securities. Changes in interest rates affect the fair market values of debt securities by influencing the discount rate applied to the securities’ future expected cash flows. The higher the discount rate, the lower the resultant security price. Conversely, the lower the discount rate, the higher the resultant security price. In addition, the cumulative amount and timing of undiscounted cash flows of debt securities may be also affected by changes in interest rates. For any given level of movement in the general market and economic environmental factors described above, the magnitude of any particular debt security’s price changes will also depend heavily upon security-specific factors such as (1) the duration of the security, (2) imbedded optionality contractually granted to the issuer of the security with respect to principal prepayments, and (3) changes in the level of market premiums demanded by investors for securities with imbedded credit risk (where applicable). The Company conducts a formal review of investment securities on a quarterly basis for the presence of OTTI. 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 securities within the portfolio as of September 30, 2019 represents OTTI. At September 30, 2019, the Bank had the following securities, in a loss position for 12 months or more relative to their amortized historical cost, which were deemed to have no credit impairment, thus, the disclosed unrealized losses relate directly to changes in interest rates subsequent to the acquisition of the individual securities. The Company does not intend to sell these securities, nor is it more likely than not that the Company will be required to sell these securities prior to the recovery of the amortized cost. • Four corporate securities, categorized as available-for-sale, with an aggregate amortized historical cost of $2.3 million and an aggregate market value of $2.3 million (unrealized aggregate loss of $12,000, or 0.53%). Each of these securities maintains a credit rating established by one or more NRSRO above the minimum level required to be considered investment grade and, therefore, no credit-related OTTI is deemed to be present. • One privately-issued asset-backed securities, categorized as available-for-sale, with an amortized historical cost of $917,000 and an aggregate market value of $895,000 (unrealized loss of $22,000 or 2.44%). This security maintains a credit rating established by one or more NRSRO above the minimum level required to be considered as investment grade and therefore, no credit-related OTTI is deemed to be present. • Four privately-issued collateralized mortgage obligation securities, categorized as available-for-sale, with an aggregate amortized historical cost of $3.5 million and an aggregate market value of $3.4 million (unrealized aggregate loss of $33,000, or 0.96%). These securities were not rated at the time of their issuance 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 an aggregate amortized historical cost of $1.4 million and an aggregate market value of $1.3 million (aggregate unrealized loss of $5,000, or 0.39%). These securities were not rated at the time of their issuance by any NRSRO but each security remains significantly collateralized through subordination. Therefore, no credit-related OTTI is deemed to be present. All other securities with market values less than their amortized historical costs for twelve or more months are issued by United States agencies or government sponsored enterprises and consist of mortgage-backed securities, collateralized mortgage obligations and direct agency financings. These positions in US government agency and government-sponsored enterprises are deemed to have no credit impairment, thus, the disclosed unrealized losses relate directly to changes in interest rates subsequent to the acquisition of the individual securities. The Company does not intend to sell these securities, nor is it more likely than not that the Company will be required to sell these securities prior to the recovery of the amortized cost. In determining whether OTTI has occurred for equity securities, the Company considers the applicable factors described above and the length of time the equity security’s fair value has been below the carrying amount. The Company had no equity investment securities that were impaired at September 30, 2019 or December 31, 2018. Gross realized gains (losses) on sales of securities for the indicated periods are detailed below: For the three months For the nine months ended September 30, ended September 30, (In thousands) 2019 2018 2019 2018 Realized gains on investments $ 143 $ 76 $ 544 $ 236 Realized losses on investments (22 ) (136 ) (312 ) (425 ) $ 121 $ (60 ) $ 232 $ (189 ) As of September 30, 2019 and December 31, 2018, securities with a fair value of $104.1 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 $22.2 million and $19.5 million were pledged against the Company’s established borrowing arrangements. Management has reviewed its loan and mortgage-backed securities portfolios and determined that, to the best of its knowledge, only minimal exposure exists to sub-prime or other high-risk residential mortgages. With limited exceptions in the Company’s investment portfolio involving the most senior tranches of securitized bonds, the Company is not in the practice of investing in, or originating, these types of investments or loans.

Compensation And Retirement Disclosure [Abstract]
Pension and Postretirement Benefits	Note 5: Pension and Postretirement Benefits The Company has a noncontributory defined benefit pension plan covering most 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 are 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 composition of net periodic pension plan and postretirement plan costs for the indicated periods is as follows: Pension Benefits Postretirement Benefits Pension Benefits Postretirement Benefits For the three months ended September 30, For the nine months ended September 30, (In thousands) 2019 2018 2019 2018 2019 2018 2019 2018 Service cost $ - $ - $ - $ - $ - $ - $ - $ - Interest cost 124 119 6 5 371 355 16 16 Expected return on plan assets (234 ) (260 ) - - (701 ) (778 ) - - Amortization of prior service credits - - (1 ) (1 ) - - (3 ) (3 ) Amortization of net losses 82 41 3 3 246 123 9 9 Net periodic benefit plan (benefit) cost $ (28 ) $ (100 ) $ 8 $ 7 $ (84 ) $ (300 ) $ 22 $ 22 The Company will evaluate the need for further contributions to the defined benefit pension plan during 2019.

Although the Bank has a diversified loan portfolio, a substantial portion of its borrowers’ abilities to honor their loan contracts is dependent upon the counties’ employment and economic conditions. The Bank acquired $15.6 million, $10.2 million, and $24.6 million of loans originated by an unrelated financial institution, located outside of the Bank’s market area, in January 2017, April 2017, and March 2019, respectively. The acquired loan pools represented a 90% participating interest in a total of 2,283 loans secured by liens on automobiles with maturities ranging primarily from two to six years. These loans will be serviced through their respective maturities by the originating financial institution. At September 30, 2019 and December 31, 2018, there were 1,731 loans outstanding with a remaining outstanding carrying value of $30.0 million and 909 loans outstanding with a remaining outstanding carrying value of $13.3 million, respectively. Since the acquisition of these loan pools, a total of 25 loans had cumulative net charge-offs totaling $187,000 with $67,000 in net charge-offs for the nine months ended September 30, 2019. The Bank acquired a $5.0 million pool of consumer loans and a $5.0 million pool of commercial and industrial loans originated by an unrelated financial institution, located outside of the Bank’s market area, in June 2019. The acquired loan pools represent a 100% interest in a total of 86 unsecured consumer loans and 35 commercial and industrial loans. These loans have maturities ranging primarily from four to ten years. At September 30, 2019, there were 85 unsecured consumer loans outstanding with a remaining outstanding carrying value of $4.8 million and 35 commercial and industrial loans outstanding with a remaining outstanding carrying value of $4.9 million. No charge-offs have occurred since the acquisition of these loan pools. The Bank acquired a $21.9 million pool of home equity lines of credit originated by an unrelated financial institution, located outside of the Bank’s market area, in August 2019. The acquired loan pools represent a 100% interest in a total of 395 secured home equity lines of credit. These lines of credit have maturities ranging primarily from four to thirty years. These lines of credit will be serviced through their respective maturities by the originating financial institution. At September 30, 2019, there were 383 secured home equity lines of credit outstanding with a remaining outstanding carrying value of $21.3 million. No charge-offs have occurred since the acquisition of these loan pools. As of September 30, 2019 and December 31, 2018, residential mortgage loans with a carrying value of $136.6 million and $154.9 million, respectively, have been pledged by the Company to the Federal Home Loan Bank of New York (“FHLBNY”) under a blanket collateral agreement to secure the Company’s line of credit and term borrowings. Loan Origination / Risk Management The Company’s lending policies and procedures are presented in Note 5 to the audited consolidated financial statements included in the 2018 Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 27, 2019 and have not changed. As part of the execution of the Company’s overall balance sheet management strategies, the Bank will acquire participating interests in loans originated by unrelated third parties on a sporadic basis. The purchase of participations in loans that are originated by third parties only occurs after the completion of thorough pre-acquisition due diligence. Loans in which the Company acquires a participating interest are determined to meet, in all material respects, the Company’s internal underwriting policies, including credit and collateral suitability thresholds, prior to acquisition. In addition, the financial condition of the originating financial institutions, which are generally retained as the ongoing loan servicing provider for participations acquired by the Bank, are analyzed prior to the acquisition of the participating interests and monitored on a regular basis thereafter for the life of those interests. To develop and document a systematic methodology for determining the allowance for loan losses, the Company has divided the loan portfolio into three portfolio segments, each with different risk characteristics but with similar methodologies for assessing risk. Each portfolio segment is broken down into loan classes where appropriate. Loan classes contain unique measurement attributes, risk characteristics, and methods for monitoring and assessing risk that are necessary to develop the allowance for loan losses. Unique characteristics such as borrower type, loan type, collateral type, and risk characteristics define each class. The following table illustrates the portfolio segments and classes for the Company’s loan portfolio: Portfolio Segment Class Residential Mortgage Loans 1-4 family first-lien residential mortgages Construction Commercial Loans Real estate Lines of credit Other commercial and industrial Tax exempt loans Consumer Loans Home equity and junior liens Other consumer The following tables present the classes of the loan portfolio, not including net deferred loan costs, summarized by the aggregate pass rating and the classified ratings of special mention, substandard and doubtful within the Company's internal risk rating system as of the dates indicated: As of September 30, 2019 Special (In thousands) Pass Mention Substandard Doubtful Total Residential mortgage loans: 1-4 family first-lien residential mortgages $ 238,192 $ 1,297 $ 1,069 $ 1,259 $ 241,817 Construction 4,241 - - - 4,241 Total residential mortgage loans 242,433 1,297 1,069 1,259 246,058 Commercial loans: Real estate 224,314 7,367 2,787 896 235,364 Lines of credit 56,687 1,339 382 - 58,408 Other commercial and industrial 75,863 3,867 1,050 49 80,829 Tax exempt loans 8,183 - - - 8,183 Total commercial loans 365,047 12,573 4,219 945 382,784 Consumer loans: Home equity and junior liens 46,840 129 234 309 47,512 Other consumer 49,146 206 134 - 49,486 Total consumer loans 95,986 335 368 309 96,998 Total loans $ 703,466 $ 14,205 $ 5,656 $ 2,513 $ 725,840 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 Management has reviewed its loan portfolio and determined that, to the best of its knowledge, no material exposure exists to sub-prime or other high-risk residential mortgages. The Company is not in the practice of originating these types of loans. 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 currently 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, as of September 30, 2019 and December 31, 2018, are detailed in the following tables: As of September 30, 2019 30-59 Days 60-89 Days 90 Days Total Total Loans (In thousands) Past Due Past Due and Over Past Due Current Receivable Residential mortgage loans: 1-4 family first-lien residential mortgages $ 1,591 $ 775 $ 777 $ 3,143 $ 238,674 $ 241,817 Construction - - - - 4,241 4,241 Total residential mortgage loans 1,591 775 777 3,143 242,915 246,058 Commercial loans: Real estate 16 151 2,845 3,012 232,352 235,364 Lines of credit 15 248 392 655 57,753 58,408 Other commercial and industrial 526 415 891 1,832 78,997 80,829 Tax exempt loans - - - - 8,183 8,183 Total commercial loans 557 814 4,128 5,499 377,285 382,784 Consumer loans: Home equity and junior liens 391 107 276 774 46,738 47,512 Other consumer 294 115 66 475 49,011 49,486 Total consumer loans 685 222 342 1,249 95,749 96,998 Total loans $ 2,833 $ 1,811 $ 5,247 $ 9,891 $ 715,949 $ 725,840 As of December 31, 2018 30-59 Days 60-89 Days 90 Days Total Total Loans (In thousands) Past Due Past Due and 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 Nonaccrual loans, segregated by class of loan, were as follows: September 30, December 31, (In thousands) 2019 2018 Residential mortgage loans: 1-4 family first-lien residential mortgages $ 777 $ 1,176 777 1,176 Commercial loans: Real estate 2,923 415 Lines of credit 392 28 Other commercial and industrial 891 387 4,206 830 Consumer loans: Home equity and junior liens 276 35 Other consumer 66 107 342 142 Total nonaccrual loans $ 5,325 $ 2,148 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. The pre-modification outstanding recorded investment is the principal loan balance less the provision for loan losses before the loan was modified as a TDR. The 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 Company had no loans that were modified as TDRs for the three months ended September 30, 2019. The table below details one loan that was modified as a TDR for the nine months ended September 30, 2019.

The Company had no loans that were modified as TDRs for the three months ended September 30, 2018. The table below details one loan that was modified as a TDR for the nine months ended September 30, 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 were modified as TDRs during the twelve months prior to September 30, 2019, which had subsequently defaulted during the nine months ended September 30, 2019. The Company had no loans that were modified as TDRs during the twelve months prior to September 30, 2018, which had subsequently defaulted during the nine months ended September 30, 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]

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: September 30, 2019 1-4 family first-lien Residential Other residential construction Commercial Commercial commercial (In thousands) mortgage mortgage real estate lines of credit and industrial Specifically reserved $ 98 $ - $ 77 $ 110 $ 339 Historical loss rate 36 - 93 37 29 Qualitative factors 513 - 3,670 909 1,420 Total $ 647 $ - $ 3,840 $ 1,056 $ 1,788 Home equity Other Tax exempt and junior liens consumer Unallocated Total Specifically reserved $ - $ 152 $ 3 $ - $ 779 Historical loss rate - 4 155 - 354 Qualitative factors 1 318 270 - 7,101 Other - - - 96 96 Total $ 1 $ 474 $ 428 $ 96 $ 8,330 September 30, 2018 1-4 family first-lien Residential Other residential construction Commercial Commercial commercial (In thousands) mortgage mortgage real estate lines of credit and industrial Specifically reserved $ 109 $ - $ 593 $ 46 $ 276 Historical loss rate 114 - 87 18 24 Qualitative factors 538 - 3,260 721 888 Total $ 761 $ - $ 3,940 $ 785 $ 1,188 Home equity Other Tax exempt and junior liens consumer Unallocated Total Specifically reserved $ - $ 140 $ - $ - $ 1,164 Historical loss rate - 21 218 - 482 Qualitative factors 1 260 212 - 5,880 Other - - - 278 278 Total $ 1 $ 421 $ 430 $ 278 $ 7,804

Commitments And Contingencies Disclosure [Abstract]
Guarantees	Note 9: Guarantees The Company does not issue any guarantees that would require liability recognition or disclosure, other than its standby letters of credit. Generally, all letters of credit, when issued have expiration dates within one year. The credit risks 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. The Company had $2.2 million of standby letters of credit as of September 30, 2019. 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. The fair value of standby letters of credit was not significant to the Company’s consolidated financial statements.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 10: Fair Value Measurements 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 available-for-sale and marketable equity securities 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. The Company holds two corporate investment securities with an aggregate amortized historical cost of $4.8 million and an aggregate fair market value of $5.0 million as of September 30, 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 the indicated dates, segregated by the level of valuation inputs within the hierarchy utilized to measure fair value: September 30, 2019 Total Fair (In thousands) Level 1 Level 2 Level 3 Value Available-for-Sale Portfolio Debt investment securities: US Treasury, agencies and GSEs $ - $ 6,986 $ - $ 6,986 State and political subdivisions - 4,807 - 4,807 Corporate - 7,621 - 7,621 Asset backed securities - 14,378 - 14,378 Residential mortgage-backed - US agency - 20,994 - 20,994 Collateralized mortgage obligations - US agency - 41,725 - 41,725 Collateralized mortgage obligations - Private label - 18,241 - 18,241 Total 114,752 114,752 Corporate measured at NAV - - - 5,044 Total available-for-sale securities $ - $ 114,752 $ - $ 119,796 Marketable equity securities $ - $ 514 $ - $ 514 Interest rate swap derivative $ - $ (115 ) $ - $ (115 ) 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 Pathfinder Bank had the following assets measured at fair value on a nonrecurring basis as of September 30, 2019 and December 31, 2018: September 30, 2019 Total Fair (In thousands) Level 1 Level 2 Level 3 Value Impaired loans $ - $ - $ 3,055 $ 3,055 Foreclosed real estate $ - $ - $ 60 $ 60 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 at the indicated dates.

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. Investment securities – The fair values of available-for-sale, held-to-maturity and marketable equity securities 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 $5.0 million as of September 30, 2019. These securities have valuations that are determined using published 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. 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 obtained from a third party pricing agent and 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, and therefore is classified within Level 2 of the fair value hierarchy.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Interest Rate Derivatives	Note 11: Interest Rate Derivatives 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. 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. 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. 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.

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 15: Subsequent Events On November 7, 2019, the Bank acquired $25.1 million of loans originated by an unrelated financial technology company, located outside of the Bank’s market area. The acquired loan pool represents a 55.9% participating interest in a total of 2,787 unsecured consumer loans with maturities ranging primarily from three to five years. These loans will be serviced through their respective maturities by the originating financial technology company. 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, if 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. As of the date of the issuance of this filing, the Company was in the process of evaluating the sale of certain conforming 30-year loans that have been held in portfolio for the past two-to-five years. The sale of loans of this type would typically reduce the overall duration of the loan portfolio and would, therefore, generally reduce the Company’s exposure to the effects of rising interest rates. As of the date of this filing, no decision has been made to sell the loans currently being evaluated. The amount of any potential sale, the expected gain or loss on such a sale, or the potential effects on future earnings of such a sale has not been determined.
