[1]	In the first quarter of 2020, consistent with policy, management reviewed all facts and circumstances related to its deferred taxes and determined that based on the expected filings of future New York State tax returns, the valuation allowance created in 2019 was no longer needed. Therefore management elected to eliminate its New York State net deferred tax asset valuation allowance during the quarter ended March 31, 2020.

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 2020 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 six months ended June 30, 2021 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2021 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 consolidated financial statements; accordingly, as this information changes, the consolidated 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 table provides a description of the accounting standards that are not currently effective, but could have an impact on the Company's consolidated financial statements upon adoption. Standards Adopted as of June 30, 2021 Standard Description Required Date of Implementation Effect on Consolidated Financial Statements Compensation (ASU 2018-14: Compensation - Retirement Benefits - Defined Benefit Plans - General [Subtopic 715 – 20]: Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans) The FASB is issuing the amendments in this ASU as part of the disclosure framework project. The amendments in this ASU modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The following disclosure requirements are removed from Subtopic 715-20: 1. The amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year. 2. The amount and timing of plan assets expected to be returned to the employer. 3. Related party disclosures about the amount of future annual benefits covered by insurance and annuity contracts and significant transactions between the employer or related parties and the plan. 4. The effects of a one-percentage-point change in assumed health care cost trend rates on the (a) aggregate of the service and interest cost components of net periodic benefit costs and (b) benefit obligation for postretirement health care benefits. The following disclosure requirements are added to Subtopic 715-20: 1. The weighted-average interest crediting rates for cash balance plans and other plans with promised interest crediting rates. 2. An explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. The amendments in this ASU also clarify the disclosure requirements in paragraph 715-20-50-3, which state that the following information for defined benefit pension plans should be disclosed: 1. The projected benefit obligation (PBO) and fair value of plan assets for plans with PBOs in excess of plan assets. 2. The accumulated benefit obligation (ABO) and fair value of plan assets for plans with ABOs in excess of plan assets. The amendments in this ASU are effective for fiscal years ending after December 15, 2020, for public business entities and for fiscal years ending after December 15, 2021, for all other entities. Early adoption is permitted for all entities. The adoption of this ASU had no material impact to the Company's consolidated statements of condition or income. Standard Description Required Date of Implementation Effect on Consolidated Financial Statements Investments (ASU 2020-01- Equity Securities [Topic 321], Investments—Equity Method and Joint Ventures [Topic 323], and Derivatives and Hedging [Topic 815]—Clarifying the Interactions between Topic 321, Topic 323, and Topic 815) The amendments in this Update clarify the interaction of the accounting for equity securities under Topic 321 and investments accounted for under the equity method of accounting in Topic 323 and the accounting for certain forward contracts and purchased options accounted for under Topic 815. The amendments clarify that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. The amendments clarify that for the purpose of applying paragraph 815-10-15-141(a) an entity should not consider whether, upon the settlement of the forward contract or exercise of the purchased option, individually or with existing investments, the underlying securities would be accounted for under the equity method in Topic 323 or the fair value option in accordance with the financial instruments guidance in Topic 825. An entity also would evaluate the remaining characteristics in paragraph 815-10-15-141 to determine the accounting for those forward contracts and purchased options. The amendments in this ASU are effective for fiscal years ending after December 15, 2020, for public business entities and for fiscal years ending after December 15, 2021, for all other entities. Early adoption is permitted for all entities. The adoption of this ASU had no material impact to the Company's consolidated statements of condition or income. Standard Description Required Date of Implementation Effect on Consolidated Financial Statements Income Taxes (ASU 2019-12- Simplifying the Accounting for Income Taxes) The FASB Board is issuing this Update as part of its initiative to reduce complexity in accounting standards (the Simplification Initiative). The amendments in this Update simplify the accounting for income taxes by removing the following exceptions, among others not considered to be applicable to the Company: 1. Exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items (for example, discontinued operations or other comprehensive income) 2. Exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The amendments in this Update also simplify the accounting for income taxes by doing the following: 1. Requiring that an entity recognize a franchise tax (or similar tax) that is partially based on income as an income-based tax and account for any incremental amount incurred as a non-income-based tax. 2. Requiring that an entity evaluate when a step up in the tax basis of goodwill should be considered part of the business combination in which the book goodwill was originally recognized and when it should be considered a separate transaction. 3. Specifying that an entity is not required to allocate the consolidated amount of current and deferred tax expense to a legal entity that is not subject to tax in its separate financial statements. However, an entity may elect to do so (on an entity-by-entity basis) for a legal entity that is both not subject to tax and disregarded by the taxing authority. 4. Requiring that an entity reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. 5. Making minor Codification improvements for income taxes related to employee stock ownership plans and investments in qualified affordable housing projects accounted for using the equity method. The amendments in this ASU are effective for fiscal years ending after December 15, 2020, for public business entities and for fiscal years ending after December 15, 2021, for all other entities. Early adoption of the amendments is permitted, including adoption in any interim period for (1) public business entities for periods for which financial statements have not yet been issued and (2) all other entities for periods for which financial statements have not yet been made available for issuance. An entity that elects to early adopt the amendments in an interim period should reflect any adjustments as of the beginning of the annual period that includes that interim period. Additionally, an entity that elects early adoption must adopt all the amendments in the same period. The adoption of this ASU had no material impact to the Company's consolidated statements of condition or income. Standard Description Required Date of Implementation Effect on Consolidated Financial Statements Reference Rate Reform (ASU 2020-04- Facilitation of the Effects of Reference Rate Reform on Financial Reporting) The amendments provide optional expedients and exceptions for applying generally accepted accounting principles (GAAP) to contracts, hedging relationships, and other transactions affected by reference rate reform. The amendments apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The amendments (1) apply to contract modifications that replace a reference rate affected by reference rate reform, (2) provide exceptions to existing guidance related to changes to the critical terms of a hedging relationship due to reference rate reform (3) provide optional expedients for fair value hedging relationships, cash flow hedging relationships, and net investment hedging relationships, and (4) provide a onetime election to sell, transfer, or both sell and transfer debt securities classified as held to maturity that reference a rate affected by reference rate reform and that are classified as held to maturity before January 1, 2020. The amendments in this Update are effective for all entities as of March 12, 2020 through December 31, 2022. The adoption of this ASU had no material impact to the Company's consolidated statements of condition or income. Standards Not Yet Adopted as of June 30, 2021 Standard Description Required Date of Implementation Effect on Consolidated Financial Statements Measurement of Credit Losses on Financial Instruments (ASU 2016-13: Financial Instruments—Credit Losses [Topic 326]: Measurement of Credit Losses on Financial Instruments) The amended guidance replaces the current incurred loss model for determining the allowance for credit losses. The guidance requires financial assets measured at amortized cost to be presented at the net amount expected to be collected. The allowance for credit losses will represent a valuation account that is deducted from the amortized cost basis of the financial assets to present their net carrying value at the amount expected to be collected. The income statement will reflect the measurement of credit losses for newly recognized financial assets as well as expected increases or decreases of expected credit losses that have taken place during the period. When determining the allowance, expected credit losses over the contractual term of the financial asset(s) (taking into account prepayments) will be estimated considering relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The amended guidance also requires recording an allowance for credit losses for purchased financial assets with a more-than-insignificant amount of credit deterioration since origination. The initial allowance for these assets will be added to the purchase price at acquisition rather than being reported as an expense. Subsequent changes in the allowance will be recorded through the income statement as an expense adjustment. In addition, the amended guidance requires credit losses relating to available-for-sale debt securities to be recorded through an allowance for credit losses. The calculation of credit losses for available-for-sale securities will be similar to how it is determined under existing guidance. January 1, 2023 (early adoption was permitted as of January 1, 2019) The Company is assessing the new guidance to determine what modifications to existing credit estimation processes may be required. The new guidance is complex and management is still evaluating the preliminary output from models that have been developed during this evaluative phase. In addition, future levels of allowances will also reflect new requirements to include estimated credit losses on investment securities classified as held-to-maturity, if any. The Company has formed an Implementation Committee, whose membership includes representatives of senior management, to develop plans that will encompass: (1) internal methodology changes (2) data collection and management activities, (3) internal communication requirements, and (4) estimation of the projected impact of this guidance. It has been generally assumed that the conversion from the incurred loss model, required under current GAAP, to the current expected credit loss (CECL) methodology (as required upon implementation of this Update) will, more likely than not, result in increases to the allowances for credit losses at many financial institutions. However, the amount of any change in the allowance for credit losses resulting from the new guidance will ultimately be impacted by the provisions of this guidance as well as by the loan and debt security portfolios composition and asset quality at the adoption date, and economic conditions and forecasts at the time of adoption. The amendments in this Update should be applied on a modified retrospective basis by means of a cumulative-effect adjustment to the opening retained earnings balance in the statement of financial position as of the date that an entity adopted the amendments in Update 2016-13. The cumulative impact of the economic effects of the COVID-19 pandemic on the changes to the allowance for loan losses, that will be required upon the implementation of the CECL methodology, cannot be estimated at this time. Standard Description Required Date of Implementation Effect on Consolidated Financial Statements Transition Relief for the Implementation of ASU-2016-13 (ASU 2019-5: Financial Instruments—Credit Losses [Topic 326]: Targeted Transition Relief) The amendments in this ASU provide entities that have certain instruments within the scope of Subtopic 326-20, Financial Instruments—Credit Losses—Measured at Amortized Cost Financial Instruments—Overall Fair Value Measurement—Overall See comments above related to ASU 2016-13. See comments above related to ASU 2016-13. Standard Description Required Date of Implementation Effect on Consolidated Financial Statements Financial Instruments—Credit Losses (ASU 2019-11- Codification Improvements to Topic 326) On June 16, 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments—Credit Losses (Topic 326) Financial Instruments—Credit Losses 1. Expected Recoveries for Purchased Financial Assets with Credit Deterioration (PCDs): The amendments clarify that the allowance for credit losses for PCD assets should include in the allowance for credit losses expected recoveries of amounts previously written off and expected to be written off by the entity and should not exceed the aggregate of amounts of the amortized cost basis previously written off and expected to be written off by an entity. In addition, the amendments clarify that when a method other than a discounted cash flow method is used to estimate expected credit losses, expected recoveries should not include any amounts that result in an acceleration of the noncredit discount. An entity may include increases in expected cash flows after acquisition. 2. Transition Relief for Troubled Debt Restructurings (TDRs): The amendments provide transition relief by permitting entities an accounting policy election to adjust the effective interest rate on existing TDRs using prepayment assumptions on the date of adoption of Topic 326 rather than the prepayment assumptions in effect immediately before the restructuring. 3. Disclosures Related to Accrued Interest Receivables: The amendments extend the disclosure relief for accrued interest receivable balances to additional relevant disclosures involving amortized cost basis. 4. Financial Assets Secured by Collateral Maintenance Provisions: The amendments clarify that an entity should assess whether it reasonably expects the borrower will be able to continually replenish collateral securing the financial asset to apply the practical expedient. The amendments clarify that an entity applying the practical expedient should estimate expected credit losses for any difference between the amount of the amortized cost basis that is greater than the fair value of the collateral securing the financial asset (that is, the unsecured portion of the amortized cost basis). An entity may determine that the expectation of nonpayment for the amount of the amortized cost basis equal to the fair value of the collateral securing the financial asset is zero. 5. Conforming Amendment to Subtopic 805-20: The amendment to Subtopic 805-20, Business Combinations—Identifiable Assets and Liabilities, and Any Noncontrolling Interest January 1, 2023 (early adoption was permitted as of January 1, 2019). The effective dates and transition requirements for the amendments are the same as the effective dates and transition requirements in Update 2016-13. The Company is assessing the new guidance to determine what modifications to existing credit estimation processes may be required. The new guidance is complex and management is still evaluating the preliminary output from models that have been developed during this evaluative phase. In addition, future levels of allowances will also reflect new requirements to include estimated credit losses on investment securities classified as held-to-maturity, if any. The Company has formed an Implementation Committee, whose membership includes representatives of senior management, to develop plans that will encompass: (1) internal methodology changes (2) data collection and management activities, (3) internal communication requirements, and (4) estimation of the projected impact of this guidance. It has been generally assumed that the conversion from the incurred loss model, required under current GAAP, to the CECL methodology will, more likely than not, result in increases to the allowances for credit losses at many financial institutions. However, the amount of any change in the allowance for credit losses resulting from the new guidance will ultimately be impacted by the provisions of this guidance as well as by the loan and debt security portfolios composition and asset quality at the adoption date, and economic conditions and forecasts at the time of adoption. The amendments in this Update should be applied on a modified retrospective basis by means of a cumulative-effect adjustment to the opening retained earnings balance in the statement of financial position as of the date that an entity adopted the amendments in Update 2016-13. Standard Description Required Date of Implementation Effect on Consolidated Financial Statements Earnings Per Share, Debt Modifications and Extinguishments, Stock Compensation, and Derivatives and Hedging- Contacts in Entity's own Equity (ASU 2011-04) The amendments in this Update affect all entities that issue freestanding written call options that are classified in equity. Specifically, the amendments affect those entities when a freestanding equity-classified written call option is modified or exchanged and remains equity classified after the modification or exchange. The amendments that relate to the recognition and measurement of EPS for certain modifications or exchanges of freestanding equity-classified written call options affect entities that present EPS in accordance with the guidance in Topic 260, Earnings Per Share. The amendments in this Update do not apply to modifications or exchanges of financial instruments that are within the scope of another Topic. That is, accounting for those instruments continues to be subject to the requirements in other Topics. The amendments in this Update do not affect a holder‘s accounting for freestanding call options. The amendments in this Update are effective for all entities for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. An entity should apply the amendments prospectively to modifications or exchanges occurring on or after the effective date of the amendments. Early adoption is permitted for all entities, including adoption in an interim period. If an entity elects to early adopt the amendments in this Update in an interim period, the guidance should be applied as of the beginning of the fiscal year that includes that interim period. The adoption of this ASU is expected to have no material impact to the Company's consolidated statements of condition or income as the Company does not have any freestanding equities with a written call option. Standard Description Required Date of Implementation Effect on Consolidated Financial Statements Leases- Topic 842 ( ASU 2021-05) The amendments in this Update affect lessors with lease contracts that (1) have variable lease payments that do not depend on a reference index or a rate and (2) would have resulted in the recognition of a selling loss at lease commencement if classified as sales-type or direct financing. The amendment requires that a lessor determine whether a lease should be classified as a sales-type lease or a direct financing lease at lease commencement on the basis of specified classification criteria (see paragraphs 842-10-25-2 through 25-3). Under ASC 842, a lessor is not permitted to estimate most variable payments and must exclude variable payments that are not estimated and do not depend on a reference index or a rate from the lease receivable. Subsequently, those excluded variable payments are recognized entirely as lease income when the changes in facts and circumstances on which those variable payments are based occur. Consequently, the net investment in the lease for a sales-type lease or a direct financing lease with variable payments of a certain magnitude that do not depend on a reference index or a rate may be less than the carrying amount of the underlying asset derecognized at lease commencement. As a result, the lessor recognizes a selling loss at lease commencement (hereinafter referred to as a day-one loss) even if the lessor expects the arrangement to be profitable overall. The amendments in this Update address stakeholders' concerns by amending the lease classification requirements for lessors to align them with practice under ASC 840. Lessors should classify and account for a lease with variable lease payments that do not depend on a reference index or a rate as an operating lease if both of the following criteria are met: (1) The lease would have been classified as a sales-type lease or a direct financing lease in accordance with the classification criteria in paragraphs 842-10-25-2 through 25-3 and (2) The lessor would have otherwise recognized a day-one loss. When a lease is classified as operating, the lessor does not recognize a net investment in the lease, does not derecognize the underlying asset, and, therefore, does not recognize a selling profit or loss. The leased asset continues to be subject to the measurement and impairment requirements under other applicable GAAP before and after the lease transaction. The amendments in this Update amend Topic 842, which has different effective dates for public business entities and most entities other than public business entities. The amendments are effective for fiscal years beginning after December 15, 2021, for all entities, and interim periods within those fiscal years for public business entities and interim periods within fiscal years beginning after December 15, 2022, for all other entities. The adoption of this ASU is currently not expected to have a material impact to the Company's consolidated statements of condition or income.

Earnings Per Share [Abstract]
Earnings per Common Share	Note 3: Earnings per Common Share Following shareholder approval received on June 4, 2021, the Company converted 1,380,283 shares of its Series B Convertible Perpetual Preferred Stock to an equal number of shares of its newly-created Series A Non-Voting Common Stock. The conversion, which was effective on June 28, 2021, represented 100% of the Company's Convertible Perpetual Preferred Stock outstanding at the time of the conversion and retired the Convertible Perpetual Preferred Stock in perpetuity. The Company has voting common stock, non-voting common stock and a warrant that are all eligible to participate in dividends equal to the voting common stock dividends on a per share basis. Securities that participate in dividends, such as the Company’s non-voting common stock and warrant, are considered “participating securities.” The Company calculates net income available to voting common shareholders using the two-class method required for capital structures that include participating securities. In applying the two-class method, basic net income per share was calculated by dividing net income (less any dividends on participating securities) by the weighted average number of shares of voting common stock and participating securities outstanding for the period. Diluted earnings per share may include the additional effect of other securities, if dilutive, in which case the dilutive effect of such securities is calculated by applying either the two-class method or the Treasury Stock method to the assumed exercise or vesting of potentially dilutive common shares. The method yielding the more dilutive result is ultimately reported for the applicable period. Potentially dilutive common stock equivalents primarily consist of employee stock options and restricted stock units. Unallocated common shares held by the ESOP are not included in the weighted average number of common shares outstanding for purposes of calculating earnings per common share until they are committed to be released to plan participants. Anti-dilutive shares are common stock equivalents with average exercise prices in excess of the weighted average market price for the period presented. Anti-dilutive stock options, not included in the computation below, were -0- for the three and six months ended June 30, 2021 and were 256,145 and $128,073 for the three and six months ended June 30, 2020, respectively.

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 June 30, 2021 represents OTTI. At June 30, 2021, 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. Of the total of ten securities in an unrealized loss position for 12 months or more at June 30, 2021, four securities, representing 67.9% of the unamortized cost of the total securities in an unrealized loss position for 12 months or more, are issued by United States agencies or Government Sponsored Enterprises (GSEs) and consist of mortgage-backed securities, collateralized mortgage obligations and direct agency financings. These positions in U.S. government agency and GSEs are deemed to have no credit impairment, thus, the disclosed unrealized losses relate primarily to changes in prepayment assumptions related to significantly lower general interest rates resulting from the economic effects of the pandemic. In addition to these four securities, the Company held the following six non-government or GSE-issued/backed securities that were in an unrealized loss position for 12 or more months at June 30, 2021: • One • One • One • One • One • One . 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 June 30, 2021 or December 31, 2020. Gross realized gains (losses) on sales and redemptions of securities for the indicated periods are detailed below: For the three months For the six months ended June 30, ended June 30, (In thousands) 2021 2020 2021 2020 Realized gains on investments $ 51 $ 917 $ 58 $ 950 Realized losses on investments - (9 ) (7 ) (16 ) $ 51 $ 908 $ 51 $ 934 As of June 30, 2021 and December 31, 2020, securities with a fair value of $109.5 million and $96.4 million, respectively, were pledged to collateralize certain municipal deposit relationships. As of the same dates, securities with a fair value of $11.9 million and $13.2 million, respectively, 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, 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 June 30, For the six months ended June 30, (In thousands) 2021 2020 2021 2020 2021 2020 2021 2020 Service cost $ - $ - $ - $ - $ - $ - $ - $ - Interest cost 111 117 2 3 221 233 6 8 Expected return on plan assets (287 ) (274 ) - - (573 ) (547 ) - - Amortization of prior service credits - - (1 ) (1 ) - - (2 ) (2 ) Amortization of net losses 25 57 2 3 50 114 4 5 Net periodic benefit plan (benefit) cost $ (151 ) $ (100 ) $ 3 $ 5 $ (302 ) $ (200 ) $ 8 $ 11 The Company will evaluate the need for further contributions to the defined benefit pension plan during 2021. The prepaid pension asset is recorded in other assets on the statement of condition as of June 30, 2021 and December 31, 2020.

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 acquires diversified pools of loans, originated by unrelated third parties, as part of the Company’s overall balance sheet management strategies. These acquisitions occurred in ten separate transactions commencing in 2019 and continuing through 2021, including two separate transactions during the six months ended June 30, 2021.

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 2020 Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 30, 2021 and have not changed. 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 June 30, 2021 Special (In thousands) Pass Mention Substandard Doubtful Total Residential mortgage loans: 1-4 family first-lien residential mortgages $ 222,785 $ 661 $ 2,724 $ 726 $ 226,896 Construction 8,133 - - - 8,133 Loans held-for-sale 713 - - - 713 Total residential mortgage loans 231,631 661 2,724 726 235,742 Commercial loans: Real estate 267,369 13,523 10,198 588 291,678 Lines of credit 51,881 4,981 3,107 128 60,097 Other commercial and industrial 62,711 3,860 6,810 1,035 74,416 Paycheck Protection Program loans 53,611 - - - 53,611 Tax exempt loans 6,554 - - - 6,554 Total commercial loans 442,126 22,364 20,115 1,751 486,356 Consumer loans: Home equity and junior liens 33,632 108 647 262 34,649 Other consumer 79,876 86 220 87 80,269 Total consumer loans 113,508 194 867 349 114,918 Total loans $ 787,265 $ 23,219 $ 23,706 $ 2,826 $ 837,016 As of December 31, 2020 Special (In thousands) Pass Mention Substandard Doubtful Total Residential mortgage loans: 1-4 family first-lien residential mortgages $ 222,386 $ 1,151 $ 3,196 $ 452 $ 227,185 Construction 6,681 - - - 6,681 Loans held-for-sale 1,526 - - - 1,526 Total residential mortgage loans 230,593 1,151 3,196 452 235,392 Commercial loans: Real estate 267,736 9,541 8,615 379 286,271 Lines of credit 40,733 5,132 3,154 84 49,103 Other commercial and industrial 65,441 4,770 8,153 265 78,629 Paycheck Protection Program loans 60,643 - - - 60,643 Tax exempt loans 7,166 - - - 7,166 Total commercial loans 441,719 19,443 19,922 728 481,812 Consumer loans: Home equity and junior liens 37,926 54 411 233 38,624 Other consumer 70,502 104 218 81 70,905 Total consumer loans 108,428 158 629 314 109,529 Total loans $ 780,740 $ 20,752 $ 23,747 $ 1,494 $ 826,733 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 June 30, 2021 and December 31, 2020, are detailed in the following tables: As of June 30, 2021 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 $ 771 $ 205 $ 871 $ 1,847 $ 225,049 $ 226,896 Construction - - - - 8,133 8,133 Loans held-for-sale - - - - 713 713 Total residential mortgage loans 771 205 871 1,847 233,895 235,742 Commercial loans: Real estate 3,331 390 3,160 6,881 284,797 291,678 Lines of credit 572 1,654 172 2,398 57,699 60,097 Other commercial and industrial 2,749 3,008 1,257 7,014 67,402 74,416 Paycheck Protection Program loans - - - - 53,611 53,611 Tax exempt loans - - - - 6,554 6,554 Total commercial loans 6,652 5,052 4,589 16,293 470,063 486,356 Consumer loans: Home equity and junior liens 156 - 291 447 34,202 34,649 Other consumer 535 235 419 1,189 79,080 80,269 Total consumer loans 691 235 710 1,636 113,282 114,918 Total loans $ 8,114 $ 5,492 $ 6,170 $ 19,776 $ 817,240 $ 837,016 As of December 31, 2020 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 $ 1,250 $ 570 $ 1,098 $ 2,918 $ 224,267 $ 227,185 Construction - - - - 6,681 6,681 Loans held-for-sale - - - - 1,526 1,526 Total residential mortgage loans 1,250 570 1,098 2,918 232,474 235,392 Commercial loans: Real estate 480 913 2,511 3,904 282,367 286,271 Lines of credit 734 1,870 194 2,798 46,305 49,103 Other commercial and industrial 441 1,717 1,691 3,849 74,780 78,629 Paycheck Protection Program loans 170 - - 170 60,473 60,643 Tax exempt loans - - - - 7,166 7,166 Total commercial loans 1,825 4,500 4,396 10,721 471,091 481,812 Consumer loans: Home equity and junior liens 248 78 473 799 37,825 38,624 Other consumer 443 252 187 882 70,023 70,905 Total consumer loans 691 330 660 1,681 107,848 109,529 Total loans $ 3,766 $ 5,400 $ 6,154 $ 15,320 $ 811,413 $ 826,733 Nonaccrual loans, segregated by class of loan, were as follows: June 30, December 31, (In thousands) 2021 2020 Residential mortgage loans: 1-4 family first-lien residential mortgages $ 2,881 $ 2,608 2,881 2,608 Commercial loans: Real estate 4,829 11,286 Lines of credit 172 194 Other commercial and industrial 6,802 6,498 11,803 17,978 Consumer loans: Home equity and junior liens 839 473 Other consumer 471 274 Total consumer loans 1,310 747 Total nonaccrual loans $ 15,994 $ 21,333 The following table summarizes nonaccrual loans by category and status at June 30, 2021: Loan Type Collateral Type Number of Loans Loan Balance Average Loan Balance Weighted LTV at Origination/ Modification Status Secured residential mortgage: Real Estate 33 $ 2,881 $ 87 88 % Under active resolution management by the Bank.

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 June 30, 2021. The table below details loans that had been modified as TDRs for the six months ended June 30, 2021.

The Company had no loans that were modified as TDRs for the three months ended June 30, 2020. The Company had no loans that were modified as TDRs for the six months ended June 30, 2020. 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 June 30, 2021, which had subsequently defaulted during the six months ended June 30, 2021. The Company had no loans that were modified as TDRs during the twelve months prior to June 30, 2020, which had subsequently defaulted during the six months ended June 30, 2020. 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, impairment is recognized as a component of the provision for loan losses, by 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	Note 7: Allowance for Loan Losses Management extensively reviews recent trends in historical losses, qualitative factors, including concentrations of loans to related borrowers and concentrations of loans by collateral type, and specific reserve needs on loans individually evaluated for impairment in its determination of the adequacy of the allowance for loan losses. We recorded $929,000 in provision for loan losses for the three month period ended June 30, 2021, as compared to $1.1 million for the three month period ended June 30, 2020. For the first six months of 2021, we recorded $2.0 million in provision for loan losses as compared to $2.2 million in the same prior year six month period. . Summarized in the tables below are changes in the allowance for loan losses for the indicated periods and information pertaining to the allocation of the allowance for loan losses, balances of the allowance for loan losses, loans receivable based in individual, and collective impairment evaluation by loan portfolio class. 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: June 30, 2021 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 $ 80 $ - $ 222 $ 904 $ 1,852 Historical loss rate 85 - 1 33 38 Qualitative factors 710 - 5,897 873 1,558 Total $ 875 $ - $ 6,120 $ 1,810 $ 3,448 Home equity Other Tax exempt and junior liens consumer Unallocated Total Specifically reserved $ - $ 223 $ - $ - $ 3,281 Historical loss rate - 325 992 - 1,474 Qualitative factors 1 257 258 - 9,554 Other - - - 294 294 Total $ 1 $ 805 $ 1,250 $ 294 $ 14,603 June 30, 2020 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 $ 153 $ - $ 64 $ 98 $ 563 Historical loss rate 71 - 99 152 61 Qualitative factors 532 - 4,095 958 1,442 Total $ 756 $ - $ 4,258 $ 1,208 $ 2,066 Home equity Other Tax exempt and junior liens consumer Unallocated Total Specifically reserved $ - $ 142 $ - $ - $ 1,020 Historical loss rate - 211 805 - 1,399 Qualitative factors 1 291 250 - 7,569 Other - - - 565 565 Total $ 1 $ 644 $ 1,055 $ 565 $ 10,553

Fair Value Measurements

Fair Value Measurements	6 Months Ended

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. Level 3 securities are assets whose fair value cannot be determined by using observable measures, such as market prices or pricing models. Level 3 assets are typically very illiquid, and fair values can only be calculated using estimates or risk-adjusted value ranges. Management applies known factors, such as currently applicable discount rates, to the valuation of those investments in order to determine fair value at the reporting date. The Company holds one corporate investment security, categorized based on its net asset value (NAV), with an amortized historical cost of $2.6 million and a fair market value of $2.8 million as of June 30, 2021. This security has a valuation that is determined using published net asset values (NAV) derived by analyses of the security’s underlying assets. This security is comprised primarily of broadly-diversified real estate properties whose fair values are determined by appraisals and other discounted cash flow evaluation methods on an infrequent basis. While this security is redeemable at least annually through tender offers made by its respective issuer, the liquidation value of the security may be below its 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 this security will be redeemed by its respective issuers on indeterminate future dates as a consequence of the ultimate liquidation strategies employed by the management of this investment. The Company holds two equity security investment s , with an aggregate value of $ 2.1 million at June 30, 2021, valued utilizing readily available market pricing (Level 1) observed from active trading on major national stock exchanges. Interest rate derivatives: The fair value of the interest rate derivatives, characterized as either fair value or cash flow hedges, are calculated based on a discounted cash flow model. All future floating rate cash flows are projected and both floating rate and fixed rate cash flows are discounted to the valuation date. The benchmark interest rate curve utilized for projecting cash flows and applying appropriate discount rates is built by obtaining publicly available third party market quotes for various swap maturity terms. Impaired loans: Impaired loans are those loans in which the Company has measured impairment based on the fair value of the loan’s collateral or the discounted value of expected future cash flows. Fair value is generally determined based upon market value evaluations by third parties of the properties and/or estimates by management of working capital collateral or discounted cash flows based upon expected proceeds. These appraisals may include up to three approaches to value: the sales comparison approach, the income approach (for income-producing property), and the cost approach. Management modifies the appraised values, if needed, to take into account recent developments in the market or other factors, such as, changes in absorption rates or market conditions from the time of valuation and anticipated sales values considering management’s plans for disposition. Such modifications to the appraised values could result in lower valuations of such collateral. Estimated costs to sell are based on current amounts of disposal costs for similar assets. These measurements are classified as Level 3 within the valuation hierarchy. Impaired loans are subject to nonrecurring fair value adjustment upon initial recognition or subsequent impairment. A portion of the allowance for loan losses is allocated to impaired loans if the value of such loans is deemed to be less than the unpaid balance. 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.

Required disclosures include fair value information of financial instruments, whether or not recognized in the consolidated statement of condition, for which it is practicable to estimate that value. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instrument. The Company has various processes and controls in place to ensure that fair value is reasonably estimated. The Company performs due diligence procedures over third-party pricing service providers in order to support their use in the valuation process. While the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Management uses its best judgment in estimating the fair value of the Company’s financial instruments; however, there are inherent weaknesses in any estimation technique. Therefore, for substantially all financial instruments, the fair value estimates herein are not necessarily indicative of the amounts the Company could have realized in a sales transaction on the dates indicated. The estimated fair value amounts have been measured as of their respective period-ends, and have not been re-evaluated or updated for purposes of these financial statements subsequent to those respective dates. As such, the estimated fair values of these financial instruments subsequent to the respective reporting dates may be different than the amounts reported at each period-end. FASB ASC Topic 820 for Fair Value Measurements and Disclosures, the financial assets and liabilities were valued at a price that represents the Company’s exit price or the price at which these instruments would be sold or transferred. The following information should not be interpreted as an estimate of the fair value of the entire Company since a fair value calculation is only provided for a limited portion of the Company’s assets and liabilities. Due to a wide range of valuation techniques and the degree of subjectivity used in making the estimates, comparisons between the Company’s disclosures and those of other companies may not be meaningful. The Company, in estimating its fair value disclosures for financial instruments, used the following methods and assumptions: Cash and cash equivalents – The carrying amounts of these assets approximate their fair value and are classified as Level 1. Federal Home Loan Bank stock – The carrying amount of these assets approximates their fair value and are classified as Level 2. Net loans – For variable-rate loans that re-price frequently, fair value is based on carrying amounts. The fair value of other loans (for example, fixed-rate commercial real estate loans, mortgage loans, and commercial and industrial loans) is estimated using discounted cash flow analysis, based on interest rates currently being offered in the market for loans with similar terms to borrowers of similar credit quality. Loan value estimates include judgments based on expected prepayment rates. The measurement of the fair value of loans, including impaired loans, is classified within Level 3 of the fair value hierarchy. Accrued interest receivable and payable – The carrying amount of these assets approximates their fair value and are classified as Level 1. Deposits – The fair values disclosed for demand deposits (e.g., interest-bearing and noninterest-bearing checking, passbook savings and certain types of money management accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts) and are classified within Level 1 of the fair value hierarchy. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered in the market on certificates of deposits to a schedule of aggregated expected monthly maturities on time deposits. Measurements of the fair value of time deposits are classified within Level 2 of the fair value hierarchy. Borrowings – Fixed/variable term “bullet” structures are valued using a replacement cost of funds approach. These borrowings are discounted to the FHLBNY advance curve. Option structured borrowings’ fair values are determined by the FHLB for borrowings that include a call or conversion option. If market pricing is not available from this source, current market indications from the FHLBNY are obtained and the borrowings are discounted to the FHLBNY advance curve less an appropriate spread to adjust for the option. These measurements are classified as Level 2 within the fair value hierarchy. Subordinated loans – The Company secures quotes from its pricing service based on a discounted cash flow methodology or utilizes observations of recent highly-similar transactions which result in a Level 2 classification.

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 changes in economic conditions. As part of managing interest rate risk, the Company enters into standardized interest rate derivative contracts (designated as hedging agreements) to modify the repricing characteristics of certain portions of the Company’s portfolios of earning assets and interest-bearing liabilities. The Company designates interest rate hedging agreements utilized in the management of interest rate risk as either fair value hedges or cash flow hedges. Interest rate hedging agreements are generally entered into with counterparties that meet established credit standards and the agreements contain master netting, collateral and/or settlement provisions protecting the at-risk party. Based on adherence to the Company’s credit standards and the presence of the netting, collateral or settlement provisions, the Company believes that the credit risk inherent in these contracts was not material at June 30, 2021. Interest rate hedging agreements are recorded at fair value as other assets or liabilities. The Company had no derivative contracts not designated as hedging agreements at June 30, 2021 or December 31, 2020. 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. In a fair value hedge, the fair value of the derivative (the interest rate hedging agreement) and changes in the fair value of the hedged item are recorded in the Company’s consolidated balance sheet with the corresponding gain or loss recognized in current earnings. The difference between changes in the fair value of the interest rate hedging agreements and the hedged items represents hedge ineffectiveness and is recorded as an adjustment to the interest income or interest expense of the respective hedged item. 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 instruments designated as a hedge. This strategy is referred to as a cash flow hedge. In a cash flow hedge, the effective portion of the derivative’s gain or loss is initially reported as a component of other comprehensive income and subsequently reclassified into earnings when the forecasted transaction affects earnings. The ineffective portion of the derivative’s gain or loss on cash flow hedges is accounted for similar to that associated with fair value hedges. Among the array of interest rate hedging contracts, potentially available to the Company, are interest rate swap and interest rate cap (or floor) contracts. The Company uses interest rate swaps, cap or floor contracts as part of its interest rate risk management strategy. Interest rate swaps 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. An interest rate cap is a type of interest rate derivative in which the buyer receives payments at the end of each contractual period in which the index interest rate exceeds the contractually agreed upon strike price rate. The purchaser of a cap contract will continue to benefit from any rise in interest rates above the strike price. Similarly, an interest rate floor is a derivative contract in which the buyer receives payments at the end of each period in which the interest rate is below the agreed strike price. The purchaser of a floor contract will continue to benefit from any rise in interest rates above the strike price. The Company records various hedges in the Consolidated Statement of Condition at fair value. The Company’s accounting treatment for these derivative instruments is based on the instruments hedge designation determined at the inception of each derivative instrument's contractual term. The following tables show the Company’s outstanding fair value hedges at June 30, 2021 and December 31, 2021: (In thousands) Carrying Amount of the Hedged Assets at June 30, 2021 Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Assets at June 30, 2021 Carrying Amount of the Hedged Assets at December 31, 2020 Cumulative Amount of Fair Value Hedging Adjustment Included in The Carrying Amount of the Hedged Assets at December 31, 2020 Line item on the balance sheet in which the hedged item is included: Loans receivable (1) $ - $ - $ 12,944 $ 53 Available-for-sale securities (2) $ 16,369 $ (831 ) $ 17,055 $ (191 ) Loans receivable (3) $ 21,690 $ (47 ) $ - $ - (1) These amounts include the amortized historical cost basis of a specific loan pool designated as the underlying asset for the hedging relationship in which the hedged item is the underlying asset's amortized cost (last layer) projected to be remaining at the end of the contractual term of the hedging instrument. The hedging instrument matured in April of 2021 and is no longer a component of the Company's Consolidated Statement of Condition at June 30, 2021. The amount of the designated hedged item was $9.2 million and the fair value of the hedging instrument resulted in a net liability position of $55,000, recorded by the Company in other liabilities at December 31, 2020. The Company’s participation in the fair value hedge had an immaterial effect on recorded interest income for the three and six months ended June 30, 2021 and 2020. (2) These amounts represent the amortized cost basis of specifically identified municipal securities designated as the underlying assets for the hedging relationship. The notional amount of the designated hedged item was $16.3 million at both June 30, 2021 and December 31, 2020. At June 30, 2021, the fair value of the derivative resulted in a net asset position of $831,000, recorded by the Company in other assets. At December 31, 2020, the fair value of the derivative resulted in a net asset position of $191,000 recorded by the Company in other assets. The Company's participation in the fair value hedge had an immaterial effect on recorded interest income for the three and six months ended June 30, 2021 and 2020 (3) These amounts include the amortized cost of a specific loan pool designated as the underlying asset for the hedging relationship in which the hedged item is the underlying asset's amortized cost (last layer) projected to be remaining at the end of the contractual term of the hedging instrument. The amount of the designated hedged item was $12.2 million at June 30, 2021. The Company did not have this derivative agreement in place at December 31, 2020. At June 30, 2021, the fair value of the derivative resulted in a net asset position of $47,000, recorded by the Company in other assets. The Company’s participation in the fair value hedge had an immaterial effect on recorded interest income for the three and six months ended June 30, 2021 and 2020 The following table shows the pre-tax losses of the Company’s derivatives designated as cash flow hedges in other comprehensive income at June 30, 2021 and December 31, 2021: (In thousands) June 30, 2021 December 31, 2020 Cash flow hedges: Total unamortized premium $ 178 $ 204 Fair market value adjustment interest rate cap (166 ) (197 ) Total unamortized cap 12 7 Fair market value adjustment interest rate swap (815 ) (1,111 ) Total loss in comprehensive income $ (981 ) $ (1,308 ) The amounts of hedge ineffectiveness, recognized during the three and six months ended June 30, 2021 and 2020 for cash flow hedges were not material to the Company’s consolidated results of operations. A portion of, or the entire amount included in accumulated other comprehensive loss would be reclassified into current earnings should a portion of, or the entire hedge, no longer be considered effective. Management believes that the hedges will remain fully effective during the remaining term of the respective hedging contracts. The changes in the fair values of the interest rate hedging agreements primarily result from the effects of changing index interest rates. The Company manages its potential credit exposure on interest rate swap transactions by entering into bilateral credit support agreements with each contractual counterparty. These agreements require collateralization of credit exposures beyond specified minimum threshold amounts. At June 30, 2021, the Company posted cash, held in an interest-bearing refundable escrow arrangement, in the amount of $1.6 million in order to satisfy collateral requirements associated with its hedging contracts.

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 Small Business Administration (“SBA”) loans, and sales of foreclosed real estate, and is earned as the transaction occurs.

Extraordinary And Unusual Items [Abstract]
COVID-19	Note 15: COVID-19 The World Health Organization (the “WHO) declared COVID-19 a global pandemic on March 11, 2020. In the United States, by the end of March 2020, the rapid spread of the COVID-19 virus invoked various Federal and New York State authorities to make emergency declarations and issue executive orders to limit the spread of the disease. Measures included severe restrictions on international and domestic travel, limitations on public gatherings, implementation of social distancing and sanitization protocols, school closings, orders to shelter in place and mandates to close all non-essential businesses to the public. To varying degrees, these very substantial mandated curtailments of social and economic activity had been progressively relaxed in the United States during the first and second quarters of 2021. This relaxation of the social and economic restrictions followed the increasingly wide-spread availability of vaccines that were first made available to the most vulnerable population segments in late 2020. These vaccines are generally considered to be effective in reducing the severity of the infection, if contracted, and in slowing the rate of spread of the coronavirus. As a result of the initial and continuing outbreak, and governmental responses thereto, the spread of the coronavirus has caused us to modify our business practices, including employee travel, employee work locations, and cancellation of physical participation in meetings, events and conferences. During the most restrictive periods during the pandemic, the Company had many of its employees working remotely and significantly reduced physical customer contact with employees and other customers until the second quarter of 2021, when New York State relaxed the majority of its safety mandates. On June 30, 2021, t he Bank’s offices and branches were fully accessible to the public. We will take further actions, focused on safety, as may be required in the future by government authorities or that we determine to be in the best interests of our employees, customers and business partners. Concerns about the spread of the disease and its anticipated negative impact on economic activity severely disrupted both domestic and international financial markets, prompting the world’s central banks to inject significant amounts of monetary stimulus into their respective economies. In the United States, the Federal Reserve System’s Federal Open Market Committee swiftly cut the target Federal Funds rate to a range of 0% to 0.25%, where it remains as of the date of this filing. The reductions in the Fed funds target rate included a 50 basis point reduction in the target federal funds rate on March 3, 2020 and an additional 100 basis point reduction on March 15, 2020. In addition, the Federal Reserve initiated various market support programs to ease the stress on financial markets. This significant reduction in short-term interest rates has reduced, and will continue to reduce, the Bank’s cost of funds and interest earning-asset yields, as long as these central bank monetary policies remain in effect. The long-term effects of the current interest rate environment, resulting from government and central bank responses to the pandemic, on the Bank’s net interest margin cannot be predicted with certainty at this time. However, it is likely that a prolonged period of the current monetary policy will result in the reduction of the Company’s net interest margin in future periods, primarily as a result of declines in interest earning-asset yields over time. The Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), signed into law on March 27, 2020, provided financial assistance in various forms to both businesses and consumers, including the establishment and funding of the Paycheck Protection Program (“PPP”). In addition, the CARES Act also created many directives affecting the operations of financial services providers, such as the Company, including a forbearance program for federally-backed mortgage loans and protections for borrowers from negative credit reporting due to loan accommodations related to the national emergency. The banking regulatory agencies likewise issued guidance encouraging financial institutions to work prudently with borrowers who were, or may be, unable to meet their contractual payment obligations because of the effects of COVID-19. The Company has worked to assist its business and consumer customers affected by COVID-19. While the CARES Act is widely-considered to have been beneficial to the economic recovery and supportive of the Company’s business activities, the long-term effect of this legislation on the operations of the Company cannot be determined with certainty at this time. On December 27, 2020, following passage by the United States Congress, President Donald J. Trump signed into law the Consolidated Appropriations Act, 2021 which included the Coronavirus Response and Relief Supplemental Appropriations Act (“CRRSAA”). The intent of this legislation was to provide another round of Economic Impact Payments to eligible individuals and families, renew the PPP to support small businesses and their employees, ensure needed access to unemployment benefits for Americans who had lost their jobs due to COVID-19, and provide additional funding for schools, vaccine distribution, and other important sectors of the economy. While CRRSSA is widely considered to have been beneficial to the economic recovery and supportive of the Company’s business activities, the long-term effect of this legislation on the operations of the Company cannot be determined with certainty at this time. On March 11, 2021, President Joseph R. Biden signed into law the American Rescue Plan Act of 2021. The intent of this legislation was to provide additional new funding for rural hospitals and health care providers for COVID-19 relief, to increase federal subsidies for COBRA coverage, and make changes to the Medicare wage index. The legislation also included provisions to bolster the nation’s COVID-19 health care response with additional resources for vaccines, treatment, personal protective equipment (PPE), testing, contact tracing and workforce development. In addition, non-health care specific provisions provide financial support for families and small businesses, and both extended and expanded support for housing, child care, food and the education system. While The American Rescue Plan Act of 2021 is expected to benefit the economic recovery and be supportive of the Company’s business activities, the effect of this legislation on the operations of the Company cannot be determined with certainty at this time. As of the date of this filing, a new variant of the coronavirus, generally referred to as the “Delta” variant, has emerged in the United States and remains a significant concern in some regions and potentially, throughout the country. This variant is believed to be significantly more contagious than earlier variants of the coronavirus. Certain previously-relaxed social distancing and safety protocols have been reinstated in some areas of the country and it is possible that such protocols will be reinstated broadly in the future. The economic effects of these varying protocol reinstatement actions on the Company’s operations cannot be determined with certainty at this time. During the most restrictive periods of the pandemic, t he Bank granted loan payment deferrals to the substantial majority of commercial and consumer customers who had made requests for such accommodations. These deferrals were granted following individual discussions with each borrower and were generally for periods of 90 or 180 days at the outset. Following discussions with certain borrowers, additional loan payment deferral periods of up to 90 days were granted following the expiration of the initial 90- to 180-day deferral periods. Typically, scheduled interest payments placed into deferred status have been added to future scheduled payments and are expected to be collected in total at the origin al maturity date of the loan. As of June 30 , 2021, the Bank had no loans on active pandemic-related deferral.
