[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 months ended March 31, 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 FASB (“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 standards adopted in the first quarter of 2021 as well as standards that are not currently effective, but could have an impact on the Company's consolidated financial statements upon adoption. Standards Adopted as of March 31, 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 March 31, 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 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 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.

Earnings Per Share [Abstract]
Earnings per Common Share	Note 3: Earnings per Common Share The Company has common stock, preferred stock and a warrant that are all eligible to participate in dividends equal to the common stock dividends on a per share basis. Securities that participate in dividends, such as the Company’s preferred stock and warrant, are considered “participating securities.” The Company calculates net income available to common shareholders using the two-class method required for capital structures that include participating securities. In applying the two-class method, basic net income per share was calculated by dividing net income (less any dividends on participating securities) by the weighted average number of shares of common stock and participating securities outstanding for the period. Diluted earnings per share may include the additional effect of other securities, if dilutive, in which case the dilutive effect of such securities is calculated by applying either the two-class method or the Treasury Stock method to the assumed exercise or vesting of potentially dilutive common shares. The method yielding the more dilutive result is ultimately reported for the applicable period. Potentially dilutive common stock equivalents primarily consist of employee stock options and restricted stock units. Unallocated common shares held by the ESOP are not included in the weighted average number of common shares outstanding for purposes of calculating earnings per common share until they are committed to be released to plan participants. Anti-dilutive shares are common stock equivalents with average exercise prices in excess of the weighted average market price for the period presented. Anti-dilutive stock options, not included in the computation below, were -0- for both the three months ended March 31, 2021 and March 31, 2020. 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 the securities portfolio as of March 31, 2021 represented OTTI. At March 31, 2021, the Bank had the following securities, not issued by the United States Government or GSE, 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 related 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. • One privately-issued asset-backed security, categorized as available-for-sale, and collateralized by leases on rail car rolling stock, with an aggregate amortized historical cost of $2.0 million (unrealized loss of $27,000, or 1.4%). This security maintains a credit rating established by one or more NRSRO above the minimum level required to be considered as investment grade and therefore, no credit-related OTTI is deemed to be present. • One privately-issued asset-backed security, categorized as available-for-sale, and collateralized by consumer installment loans with an aggregate amortized historical cost of $244,000 (unrealized loss of less than $1,000). This security was not rated at the time of their issuances by any NRSRO but each security remains significantly collateralized through subordination and other credit enhancements. Therefore, no credit-related OTTI is deemed to be present • Three privately-issued collateralized mortgage obligation securities, collateralized by residential and commercial mortgage loans and categorized as available-for-sale, with an aggregate amortized historical cost of $2.2 million and an aggregate market value of $2.2 million (unrealized aggregate loss of $21,000 or -0.9%). These securities were not rated at the time of their issuances by any NRSRO but each security remains significantly collateralized through subordination and other credit enhancements. Therefore, no credit-related OTTI is deemed to be present. • One municipal security, categorized as held-to-maturity with an amortized historical cost of $3.0 million and a market value of $3.0 million (unrealized loss of $4,000 or -0.1%). This security was unrated at issuance but the underlying issuer has maintained strong financial metrics. Therefore, no credit-related OTTI is deemed to be present. • Four privately-issued asset-backed securities, collateralized by various non-real estate assets, and categorized as held-to-maturity, with an aggregate amortized historical cost of $3.2 million and an aggregate market value of $3.2 million (unrealized aggregate loss of $24,000 or -0.8%). These securities were not rated at the time of their issuances by any NRSRO but each security remains significantly collateralized through subordination and other credit enhancements. Therefore, no credit-related OTTI is deemed to be present. • One privately-issued asset-backed security, categorized as held-to-maturity and collateralized by private-issue student loans, with an aggregate amortized historical cost of $1.8 million and an aggregate market value of $1.7 million (unrealized loss of $92,000 or -5.3%). This security was unrated at issuance but remains sufficiently collateralized through subordination. Therefore, no credit-related OTTI is deemed to be present. • One privately-issued collateralized mortgage obligation security, collateralized by residential mortgage loans and categorized as held-to-maturity, with an aggregate amortized historical cost of $639,000 and a market value of $638,000 (unrealized loss of $1,000 or -0.2%). This security maintains a credit rating established by one or more NRSRO above the minimum level required to be considered as investment grade and therefore, no credit-related OTTI is deemed to be present. All other securities with market values less than their amortized historical costs 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 related 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 securities that were impaired at March 31, 2021 or December 31, 2020. Gross realized gains (losses) on sales of securities for the indicated periods are detailed below: For the three months ended March 31, (In thousands) 2021 2020 Realized gains on investments $ 7 $ 33 Realized losses on investments (7 ) (7 ) $ - $ 26 As of March 31, 2021 and December 31, 2020, securities with a fair value of $125.3 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 mortgage-backed securities portfolios and determined that, to the best of its knowledge, little 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 For the three months ended March 31, (In thousands) 2021 2020 2021 2020 Service cost $ - $ - $ - $ - Interest cost 110 116 3 4 Expected return on plan assets (286 ) (273 ) - - Amortization of prior service credits - - (1 ) (1 ) Amortization of net losses 25 57 2 2 Net periodic benefit plan (benefit) cost $ (151 ) $ (100 ) $ 4 $ 5 The Company will evaluate the need for further contributions to the defined benefit pension plan during 2021.

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 three months ended March 31, 2021. The following table sets forth certain information related to these loan transactions: March 31, December 31, (In thousands, except number of loans) 2021 2020 Purchased residential real estate loans Original Balance $ 4,300 $ 4,300 Current Balance $ 4,200 $ 4,300 Unamortized Premium (Discount) $ 270 $ 273 Percent Owned 100 % 100 % Number of Loans 51 51 Maturity range 17-24 years 17-25 years Cumulative net charge-offs $ - $ - Purchased other commercial and industrial loans Original Balance $ 6,800 $ 6,800 Current Balance $ 5,400 $ 5,500 Unamortized Premium (Discount) $ - $ - Percent Owned 100 % 100 % Number of Loans 39 39 Maturity range 4-8 years 5-9 years Cumulative net charge-offs $ - $ - Purchased home equity lines of credit: Original Balance $ 21,900 $ 21,900 Current Balance $ 12,400 $ 13,900 Unamortized Premium (Discount) $ 291 $ 309 Percent Owned 100 % 100 % Number of Loans 252 275 Maturity range 3-28 years 3-29 years Cumulative net charge-offs $ - $ - Purchased automobile loans: Original Balance $ 50,400 $ 50,400 Current Balance $ 14,600 $ 17,000 Unamortized Premium (Discount) $ 527 $ 602 Percent Owned 90 % 90 % Number of Loans 1,133 1,257 Maturity range 0-6 years 0-6 years Cumulative net charge-offs $ 232 $ 230 March 31, December 31, (In thousands, except number of loans) 2021 2020 Purchased unsecured consumer loan pool 1: Original Balance $ 5,400 $ 5,400 Current Balance $ 3,300 $ 3,600 Unamortized Premium (Discount) $ - $ - Percent Owned 100 % 100 % Number of Loans 72 76 Maturity range 3-6 years 3-6 years Cumulative net charge-offs $ - $ - Purchased unsecured consumer loan pool 2: Original Balance $ 26,600 $ 26,600 Current Balance $ 12,900 $ 15,400 Unamortized Premium (Discount) $ 53 $ 63 Percent Owned 59 % 59 % Number of Loans 2,075 2,246 Maturity range 1-5 years 2-4 years Cumulative net charge-offs $ - $ - Purchased unsecured consumer loan pool 3: Original Balance $ 10,300 $ 10,300 Current Balance $ 4,400 $ 5,500 Unamortized Premium (Discount) $ 118 $ 138 Percent Owned 100 % 100 % Number of Loans 2,495 2,958 Maturity range 0-6 years 0-6 years Cumulative net charge-offs $ 3 $ - Purchased secured consumer loan pool 1: Original Balance $ 14,500 $ 14,500 Current Balance $ 14,300 $ 14,500 Unamortized Premium (Discount) $ (2,032 ) $ (2,124 ) Percent Owned 68 % 68 % Number of Loans 612 619 Maturity range 25 years 25 years Cumulative net charge-offs $ - $ - Purchased secured consumer loan pool 2: Original Balance $ 24,400 $ - Current Balance $ 23,600 $ - Unamortized Premium (Discount) $ (662 ) $ - Percent Owned 100 % 0 % Number of Loans 844 - Maturity range 10-24 years - Cumulative net charge-offs $ - $ - Purchased commercial line of credit: Original Balance $ 11,600 $ - Current Balance $ 11,600 $ - Unamortized Premium (Discount) $ 35 $ - Percent Owned 12 % 0 % Number of Loans 1 - Maturity range 3 years - Cumulative net charge-offs $ - $ - As of March 31, 2021 and December 31, 2020, residential mortgage loans with a carrying value of $119.8 million and $115.6 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 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 March 31, 2021 Special (In thousands) Pass Mention Substandard Doubtful Total Residential mortgage loans: 1-4 family first-lien residential mortgages $ 221,499 $ 1,111 $ 2,841 $ 607 $ 226,058 Construction 7,789 - - - 7,789 Loans held-for-sale 437 - - - 437 Total residential mortgage loans 229,725 1,111 2,841 607 234,284 Commercial loans: Real estate 267,008 13,108 8,547 519 289,182 Lines of credit 54,838 5,125 3,114 81 63,158 Other commercial and industrial 64,420 5,130 7,932 433 77,915 Paycheck Protection Program loans 71,885 - - - 71,885 Tax exempt loans 6,959 - - - 6,959 Total commercial loans 465,110 23,363 19,593 1,033 509,099 Consumer loans: Home equity and junior liens 35,138 130 681 232 36,181 Other consumer 87,480 140 274 82 87,976 Total consumer loans 122,618 270 955 314 124,157 Total loans $ 817,453 $ 24,744 $ 23,389 $ 1,954 $ 867,540 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 3,196 728 235,392 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 March 31, 2021 and December 31, 2020, are detailed in the following tables: As of March 31, 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 $ 132 $ 482 $ 776 $ 1,390 $ 224,668 $ 226,058 Construction - - - - 7,789 7,789 Loans held-for-sale - - - - 437 437 Total residential mortgage loans 132 482 776 1,390 232,894 234,284 Commercial loans: Real estate 2,943 3,555 2,574 9,072 280,110 289,182 Lines of credit 1,461 900 196 2,557 60,601 63,158 Other commercial and industrial 515 1,420 1,214 3,149 74,766 77,915 Paycheck Protection Program loans - - - - 71,885 71,885 Tax exempt loans - - - - 6,959 6,959 Total commercial loans 4,919 5,875 3,984 14,778 494,321 509,099 Consumer loans: Home equity and junior liens 63 13 291 367 35,814 36,181 Other consumer 411 279 186 876 87,100 87,976 Total consumer loans 474 292 477 1,243 122,914 124,157 Total loans $ 5,525 $ 6,649 $ 5,237 $ 17,411 $ 850,129 $ 867,540 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 480 100 2,271 3,324 250,933 286,271 Lines of credit 734 25 68 4,557 54,060 49,103 Other commercial and industrial 441 315 591 3,653 78,439 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: March 31, December 31, (In thousands) 2021 2020 Residential mortgage loans: 1-4 family first-lien residential mortgages $ 2,899 $ 2,608 2,899 2,608 Commercial loans: Real estate 11,449 11,286 Lines of credit 196 194 Other commercial and industrial 6,197 6,498 17,842 17,978 Consumer loans: Home equity and junior liens 337 473 Other consumer 265 274 Total consumer loans 602 747 Total nonaccrual loans $ 21,343 $ 21,333 The following table summarizes nonaccrual loans by category and status at March 31, 2021: Loan Type Collateral Type Number of Loans Loan Balance Average Loan Balance Weighted LTV at Origination/ Modification Status Loan Balance In Deferral Secured residential mortgage: Real Estate 33 $ 2,899 $ 88 85 % Under active resolution management by the Bank. $ 107 Secured commercial real estate: Hotel 1 7,202 7,202 73 % Currently making principal and interest payments.

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 table below details loans that had been modified as TDRs for the three months ended March 31, 2021. For the three months ended March 31, 2021 (In thousands) Number of loans Pre-modification outstanding recorded investment Post-modification outstanding recorded investment Additional provision for loan losses Commercial loans 2 $ 961 $ 967 6 Residential real estate loans 2 $ 389 $ 389 $ 12 Home equity and junior liens 1 $ 200 $ 504 $ 219 The loans evaluated for impairment for the three months ended March 31, 2021 have been classified as TDRs due to economic concessions granted, which consisted of a reduction in the stated interest rate, a significant delay in the timing of the payment or an extended maturity date that will result in a significant delay in payment from the original terms. The Company had no loans that have been modified as TDRs for the three months ended March 31, 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 had been modified as TDRs during the twelve months prior to March 31, 2021, which had subsequently defaulted during the three months ended March 31, 2021. The Company had no loans that had been modified as TDRs during the twelve months prior to March 31, 2020, which had subsequently defaulted during the three months ended March 31, 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, then impairment is recognized as a component of the provision for loan losses, an associated increase to the allowance for loan losses or as a charge-off to the allowance for loan losses in the current period.

Allowance For Loan Losses [Abstract]
Allowance for Loan Losses	Note 7: Allowance for Loan Losses Management extensively reviews recent trends in changes in the size and composition of the loan portfolio, historical loss experience, qualitative factors, and specific reserve needs on loans individually evaluated for impairment, in its determination of the adequacy of the allowance for loan losses. The Company recorded $1.0 million in provision for loan losses for the three-month period ended March 31, 2021, as compared to $1.1 million for the three-month period ended March 31, 2020. The provision for loan losses in the first quarter of 2021 and 2020, resulted from year-over-year increases in: (1) the qualitative factors used in determining the adequacy of the allowance for loan losses, (2) the size of the loan portfolio, and (3) delinquent and nonaccrual loans. The increase in the quantitative factors used in determining the provision for loan losses reflects the substantial increase in economic uncertainty and the resultant potential for increased credit losses in future periods as a consequence of the COVID-19 pandemic. Outstanding loan balances, excluding PPP loans, increased $42.9 million, or 5.7%, in the quarter ended March 31, 2021, as compared to the same quarter in the previous year, and therefore required a corresponding increase in the estimable and probable loan losses inherent in the loan portfolio. Finally, the provision for loan losses in the quarter ended March 31, 2021 was further increased by the effects of an increase in nonaccrual loans that increased $16.6 million to $21.3 million at March 31, 2021 as compared to $4.7 million at March 31, 2020.

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.

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 $2.4 million of standby letters of credit as of March 31, 2021. 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 Measurements

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 aggregate amortized historical cost of $2.6 million and an aggregate fair market value of $2.8 million as of March 31, 2021. This security has valuations that are 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 and adjustable-rate senior secured business loans and are traded in secondary markets 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. 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. 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: March 31, 2021 Total Fair (In thousands) Level 1 Level 2 Level 3 Value Available-for-Sale Portfolio Debt investment securities: US Treasury, agencies and GSEs $ - $ 23,402 $ - $ 23,402 State and political subdivisions - 23,188 - 23,188 Corporate - 10,415 - 10,415 Asset backed securities - 13,196 - 13,196 Residential mortgage-backed - US agency - 24,962 - 24,962 Collateralized mortgage obligations - US agency - 29,981 - 29,981 Collateralized mortgage obligations - Private label - 30,926 - 30,926 Total 156,070 156,070 Corporate measured at NAV - - - 2,804 Total available-for-sale securities $ - $ 156,070 $ - $ 158,874 Marketable equity securities $ 2,084 $ - $ - $ 2,084 Interest rate swap derivative fair value hedges $ - $ 1,318 $ - $ 1,318 Interest rate swap derivative cash flow hedges $ - $ (1,074 ) $ - $ (1,074 ) December 31, 2020 Total Fair (In thousands) Level 1 Level 2 Level 3 Value Available-for-Sale Portfolio Debt investment securities: US Treasury, agencies and GSEs $ - $ 6,416 $ - $ 6,416 State and political subdivisions - 23,753 - 23,753 Corporate - 9,943 - 9,943 Asset backed securities - 8,607 - 8,607 Residential mortgage-backed - US agency - 25,211 - 25,211 Collateralized mortgage obligations - US agency - 26,464 - 26,464 Collateralized mortgage obligations - Private label - 24,936 - 24,936 Total - 125,330 - 125,330 Corporate measured at NAV - - - 2,725 Total available-for-sale securities $ - $ 125,330 $ - $ 128,055 Marketable equity securities $ 1,850 $ - $ - $ 1,850 Interest rate swap derivative fair value hedge 136 136 Interest rate swap derivative fair value hedge $ - $ (1,308 ) $ - $ (1,308 ) Pathfinder Bank had the following assets measured at fair value on a nonrecurring basis as of March 31, 2021 and December 31, 2020: March 31, 2021 Total Fair (In thousands) Level 1 Level 2 Level 3 Value Impaired loans $ - $ - $ 1,698 $ 1,698 December 31, 2020 Total Fair (In thousands) Level 1 Level 2 Level 3 Value Impaired loans $ - $ - $ 14,701 $ 14,701 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. 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 Derivative

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 March 31, 2021. Interest rate hedging agreements 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 entered into a pay-fixed/receive variable interest rate swap with a notional amount of $9.2 million in April 2019. The swap agreement was designated as a fair value hedge and was linked to a specific pool of loans within the Company’s fixed-rate consumer loan portfolio. Under the swap agreement, the Company paid a fixed-rate of 2.39% per annum to the swap counterparty, while receiving 3-month LIBOR indexed payments from the same counterparty, with both payments calculated on the notional amount. The swap agreement expired in April 2021 and management does not intend to renew the arrangement. As of March 31, 2021 and December 31, 2020, the following amounts were recorded on the balance sheet related to the cumulative basis adjustments for this fair value hedge: (In thousands) Carrying Amount of the Hedged Assets at March 31, 2021 Cumulative Amount of Fair Value Hedging Adjustment Included in The Carrying Amount of the Hedged Assets at March 31, 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) $ 11,345 $ 5 $ 12,944 $ 53 (1) These amounts include the amortized cost basis of the hedged portfolio used to designate the hedging relationship in which the hedged item is the remaining amortized cost of the last layer expected to be remaining at the end of the hedging contract term. At March 31, 2021 and December 31, 2020, the amortized cost of the basis of the closed portfolio used in the hedging relationship was $11.3 million and $12.9 million, the cumulative basis adjustment associated with the hedging relationship was $5,000 and $53,000, and the amount of the designated hedged item was $9.2 million and $9.2 million, respectively. At March 31, 2021 and December 31, 2020, the fair value of the fair value derivative resulted in a net liability position of $5,000 and $55,000 under the agreement, respectively, recorded by the Company in other liabilities. The Company’s participation in the swap contract had an immaterial effect on recorded interest income for the three months ended March 31, 2021. In February 2020, the Company entered into an interest rate cap contract in the notional amount of $40.0 million, intended to reduce the Company’s exposure to potential rising interest rates. This contractual agreement has been designated as a cash flow hedge with changes in the fair value of the contract, net of changes in the fair value of the designated hedged liability (certain short-term certificates of deposit with rates of interest that are highly correlated to the 3-month LIBOR index) being accounted for through other comprehensive income. The term of the cap contract commenced on May 1, 2020 and expire on May 1, 2023. The Company paid $228,000 in a one-time premium for the cap contract and has no further contractual obligations to the counterparty over the three-year life of the contract. The premium will be amortized ratably over the contractual term of the cap contract with an annual average cost to the Company of approximately 19 basis points relative to the notional amount. The Company will potentially benefit during the term of this cap contract, in the manner described above, for the period of time that the 3-month LIBOR index exceeds 1.85% (the strike price). The cap contract had no effect on recorded interest expense in the quarter ended March 31, 2021. In March 2020, the Company entered into an interest rate swap contract in the notional amount of $40.0 million, intended to reduce the Company’s exposure to potential rising interest rates. This contractual agreement has been designated as a cash flow hedge with changes in the fair value of the contract, net of changes in the fair value of the designated hedged liability (certain short-term certificates of deposit with rates of interest that are highly correlated to the 3-month LIBOR index) being accounted for through other comprehensive income. The term of the swap contract will commence on May 15, 2020 and expire on May 15, 2023. Under the terms of the swap contract, the Company will be obligated to pay the contractual counterparty an annual rate of 1.39% (the strike price) times the notional amount of the contract. Simultaneously, for the duration of the swap contract, the counterparty will be obligated to pay the Company the annual rate of the 3-month LIBOR index, as determined each calendar quarter, times the notional contractual amount. The swap contract had no effect on recorded interest expense in the quarter ended March 31, 2021. (In thousands) March 31, 2021 December 31, 2020 Cash flow hedges: Total unamortized premium $ 192 $ 204 Fair market value adjustment interest rate cap (169 ) (197 ) Total unamortized cap 23 7 Fair market value adjustment interest rate swap (905 ) (1,111 ) Total loss in comprehensive income $ (1,074 ) $ (1,308 ) The amounts of hedge ineffectiveness, recognized during the quarter ended March 31, 2021, for cash flow hedges were not material to the Company’s consolidated results of operations. Some or the entire amount included in accumulated other comprehensive loss would be reclassified into current earnings should a portion of, or the entire hedge no longer be considered effective, but at this time, management expects the hedge to remain fully effective during the remaining term of the swap. The changes in the fair values of the interest rate hedging agreements and the hedged items primarily result from the effects of changing interest rates and spreads. From time to time, the Company purchases high credit-quality securities with long maturity dates. In order to reduce the Company's exposure to potential declines in the fair value of such securities, particularly in a rising interest rate environment, the Company has elected to enter into fixed-pay, receive floating rate interest rate swap contracts, designated as fair value hedges. The maturity dates of the swaps are matched exactly to the first call date of the seven hedged securities. During 2020, the Company entered into five swap contracts of this type with a total notional amount of $16.3 million. The objective of the hedges is to protect the hedged securities of the Bank against changes in fair value due to changes in the benchmark interest rate. Changes in the fair value of the interest rate swap are expected to be “perfectly effective” in offsetting changes in the fair value of the hedged item attributable to changes in the LIBOR swap rate, the designated benchmark interest rate.

At December 31, 2020, the fair value of the derivative resulted in a net asset position of $191,000 under the agreement, respectively, recorded by the Company in other assets. The fair value hedge had an immaterial effect on recorded interest income for the three months ended March 31, 2021. The Company entered into a pay-fixed/receive variable interest rate swap with a notional amount of $12.2 million in February 2021, which was designated as a fair value hedge, associated with specific pools within the Company’s fixed-rate consumer loan portfolio. As of March 31, 2021 and December 31, 2020, the following amounts were recorded on the balance sheet related to the cumulative basis adjustments for this fair value hedge: (In thousands) Carrying Amount of the Hedged Assets at March 31, 2021 Cumulative Amount of Fair Value Hedging Adjustment Included in The Carrying Amount of the Hedged Assets at March 31, 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) $ 23,479 $ (36 ) $ - $ - (1) These amounts include the amortized cost basis of the closed portfolio used to designate the hedging relationship in which the hedged item is the remaining amortized cost of the last layer expected to be remaining at the end of the hedging relationship. At March 31, 2021, the amortized cost of the basis of the closed portfolio used in the hedging relationship was $23.4 million, the cumulative basis adjustment associated with the hedging relationship was $36,000, and the amount of the designated hedged item was $12.2 million. The Company did not have this derivative agreement in place at December 31, 2020. At March 31, 2021, the fair value of the derivative resulted in a net asset position of $36,000 under the agreement, recorded by the Company in other assets. The Company’s participation in the swap contract had an immaterial effect on recorded interest income for the three months ended March 31, 2021. The Company manages its potential credit exposure on interest rate swap transactions by entering into bilateral credit support agreements with each counterparty. These agreements require collateralization of credit exposures beyond specified minimum threshold amounts. The Company posted cash in escrow of $1.6 million under collateral arrangements to satisfy collateral requirements associated with the interest rate swap contract.

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

COVID-19

COVID-19	3 Months Ended
	Mar. 31, 2021
Extraordinary And Unusual Items [Abstract]
COVID-19	Note 15: COVID-19 In early January 2020, the World Health Organization issued an alert that a novel coronavirus outbreak was emanating from Wuhan, Hubei Province in China. Over the course of the next several weeks, the outbreak continued to spread to various regions of the world, prompting the World Health Organization to declare COVID-19 a global pandemic on March 11, 2020. In the United States, by the end of March 2020, the rapid spread of the COVID-19 virus invoked various Federal and New York State authorities to make emergency declarations and issue executive orders to limit the spread of the disease. Measures included restrictions on international and domestic travel, limitations on public gatherings, implementation of social distancing and sanitization protocols, school closings, orders to shelter in place and mandates to close all non-essential businesses to the public. To widely varying degrees, largely dependent upon the level of regional and national outbreaks and the resultant levels of strain on available medical resources, these very substantial mandated curtailments of social and economic activity had been relaxed in the United States during the first quarter of 2021. This relaxation of the curtailments followed a pattern of very gradual relaxation of those curtailments in the later part of 2020. However, there are still virtually no localities within the United States that have completely returned to substantively normal business and social activities at the time of this filing. This discussion would apply directly to the curtailments that have occurred and continue to occur, to lessening degrees, within the Company’s primary service areas. As a result of the initial and continuing outbreak, and governmental responses thereto, the spread of the coronavirus has caused us to modify our business practices, including employee travel, employee work locations, and cancellation of physical participation in meetings, events and conferences. The Company has many employees working remotely and has significantly reduced physical customer contact with employees and other customers. Initially, branch activities were limited to drive-thru transactions whenever possible, teleconferencing and in-branch “appointments only” services. The Bank’s branches are now fully accessible to the public but remain in strict compliance with all applicable social distancing and sanitization guidelines. Since the start of the pandemic, transactional volume has also increased through the Bank’s telephone, mobile and internet banking channels. We will take further actions, focused on safety, as may be required by government authorities or that we determine to be in the best interests of our employees, customers and business partners. Concerns about the spread of the disease and its anticipated negative impact on economic activity, severely disrupted both domestic and international financial markets prompting the world’s central banks to inject significant amounts of monetary stimulus into their respective economies. In the United States, the Federal Reserve System’s Federal Open Market Committee, swiftly cut the target Federal Funds rate to a range of 0% to 0.25%, where it remains as of the date of this filing. The reductions in the Fed funds target rate included a 50 basis point reduction in the target federal funds rate on March 3, 2020 and an additional 100 basis point reduction on March 15, 2020. In addition, the Federal Reserve initiated various market support programs to ease the stress on financial markets. This significant reduction in short-term interest rates has reduced, and will continue to reduce, the Bank’s cost of funds and interest earning-asset yields. The long-term effects of the current interest rate environment, resulting from government and central bank responses to the pandemic, on the Bank’s net interest margin cannot be predicted with certainty at this time. The Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), signed into law on March 27, 2020, provided financial assistance in various forms to both businesses and consumers, including the establishment and funding of the Paycheck Protection Program (“PPP”). In addition, the CARES Act also created many directives affecting the operations of financial services providers, such as the Company, including a forbearance program for federally-backed mortgage loans and protections for borrowers from negative credit reporting due to loan accommodations related to the national emergency. The banking regulatory agencies have likewise issued guidance encouraging financial institutions to work prudently with borrowers who are, or may be, unable to meet their contractual payment obligations because of the effects of COVID-19. The Company has worked to assist its business and consumer customers affected by COVID-19. On December 27, 2020, following passage by the United States Congress, President Donald Trump signed into law the Consolidated Appropriations Act, 2021 which included the Coronavirus Response and Relief Supplemental Appropriations Act (“CRRSAA”). The intent of this legislation was to provide another round of Economic Impact Payments to eligible individuals and families, renew the PPP to support small businesses and their employees, ensure needed access to unemployment benefits for Americans who have lost their jobs due to COVID-19, and provide additional funding for schools, vaccine distribution, and other important sectors of the economy. While CRRSSA is expected to benefit the economic recovery and be supportive of the Company’s business activities, the effect of this legislation on the operations of the Company cannot be determined with certainty at this time. On March 11, 2021, President Joseph 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 includes 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, as well as extend and expand 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. The 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 original maturity date of the loan. As of March 31, 2021, the Bank had active deferrals on a total of 17 loans with aggregated outstanding balances of $8.4 million. Of that total, eight deferred loans were either residential mortgage loans or consumer loans. These two categories of deferred loans had outstanding loan principal balances totaling $793,000 at March 31, 2021. Of the eight residential mortgage loans or consumer loans in deferral status at March 31, 2021, one loan, representing $107,000 is also in nonaccrual status at that date and has been included in the nonaccrual loan totals. Due to the substantially smaller outstanding balances of individual loans within these categories and the presence of significant collateralization in the case of residential mortgage loans, management does not consider the loans in these categories to be at increased risk of impairment as a result of their deferral status. Of the nine remaining loans granted deferral status at March 31, 2021, $7.6 million were commercial real estate or commercial & industrial loans (collectively, “commercial” loans). Of the nine commercial loans in deferral status at March 31, 2021, six loans, representing $6.2 million are also in nonaccrual status at that date. Of this $6.2 million in deferred commercial loans, $500,000 have deferral periods that have been extended beyond a cumulative total of 180 days through granted additional deferral periods. Borrowers that were delinquent in their payments to the Bank, prior to requesting a COVID-19 related financial hardship payment deferral were reviewed on a case by case basis for troubled debt restructure classification and non-performing loan status. In the instances where the Company granted a payment deferral to a delinquent borrower because of COVID-19, the borrower’s delinquency status was frozen as of February 29, 2020, and their loans will continue to be reported as delinquent during the deferment period based on their delinquency status as of that date. The long-term collectability of deferred loan payments will depend on many factors, including the future progression of the pandemic, potential medical breakthroughs in therapeutic treatments and/or vaccines, the pace of vaccine distributions, further economic stimulus from government authorities, the rate at which governmental restrictions on business activities are relaxed and the adequacy and sustainability of other sources of repayment such as loan collateral. Consistent with industry regulatory guidance, borrowers that were granted COVID-19 related deferrals but were otherwise current on loan payments will continue to have their loans reported as current loans during the agreed upon deferral period(s), accrue interest and not be accounted for as troubled debt restructurings. The future performance of the Company’s loan portfolios with respect to credit losses will be highly dependent upon the course and duration, both nationally and within the Company’s market area, of the public health and economic factors related to the pandemic, as well as the concentrations in the Company’s loan portfolio. Concentrations of loans within a portfolio that are made to a single borrower, to a related group of borrowers, or to a limited number of industries, are generally considered to be additional risk factors in estimating future credit losses. Therefore, the Company monitors all of its credit relationships to ensure that the total loan amounts extended to one borrower, or to a related group of borrowers, does not exceed the maximum permissible levels defined by applicable regulation or the Company’s generally more restrictive internal policy limits. Loans to a single borrower, or to a related group of borrowers, are referred to as related credits. Total related credits encompass all related or affiliated borrower loan balances, including available unused lines of credit, for both personal and business loans. At March 31, 2021, the Company had 29 total related credit relationships, comprised of 294 individual loans, with outstanding balances in excess of $5.0 million. These total related credits ranged from $5.0 million to $16.5 million at March 31, 2021 with aggregate balances of $258.7 million. Of the $258.7 million in total related credits, $236.7 million was secured by various collateral assets, primarily commercial real estate, $6.5 million was unsecured, and $15.5 million were PPP loans. In addition, the future credit-related performance of a loan portfolio generally depends upon the types of loans within the portfolio, concentrations by type of loan and the quality of the collateral securing the loans. The following table details the Company's loan portfolio by collateral type within major categories as of March 31, 2021: (Dollars in thousands) Balance Number of Loans Average Loan Balance Minimum/ Maximum Loan Balance Allowance for Loan Losses Percent of Total Loans Residential Mortgage Loans $ 234,284 2,121 $ 110 $ 0 - $ 1,536 $ 975 27 % Commercial Real Estate: Mixed Use $ 50,392 56 $ 900 $ 44 - $ 7,433 $ 997 6 % Multi-Family Residential 43,886 60 731 25 - 6,275 868 5 % Hotels and Motels 35,198 10 3,520 334 - 11,500 696 4 % Office 34,587 62 558 7 - 4,835 684 4 % Retail 23,200 45 516 32 - 5,124 459 3 % 1-4 Family Residential 19,449 150 130 8 - 1,222 385 2 % Automobile Dealership 16,250 10 1,625 167 - 6,741 321 2 % Warehouse 9,961 13 766 73 - 2,696 197 1 % Recreation/ Golf Course/ Marina 11,533 15 769 23 - 3,150 228 1 % Skilled Nursing Facility 10,896 2 5,448 3,800 - 7,096 216 1 % Manufacturing/Industrial 7,443 15 496 91 - 1,415 147 1 % Restaurant 6,300 24 263 43 - 1,251 125 1 % Automobile Repair 4,756 11 432 52 - 2,312 94 1 % Not-For-Profit & Community Service Real Estate 3,451 3 1,150 106 - 1,778 68 1 % Hospitals 3,375 3 1,125 77 - 3,105 67 0 % Land 2,406 4 602 70 - 2,000 48 0 % All Other 6,099 31 197 5 - 739 121 1 % Total Commercial Real Estate Loans $ 289,182 514 $ 563 $ 5,721 34 % Commercial and Industrial: Secured Term Loans $ 61,201 378 $ 162 $ - - $ 4,485 $ 2,369 7 % Unsecured Term Loans 16,715 118 142 1 - 2,244 647 2 % Secured Lines of Credit 53,857 263 205 - - 11,588 1,634 6 % Unsecured Lines of Credit 9,300 139 67 - - 2,750 282 1 % Total Commercial and Industrial Loans $ 141,073 898 $ 157 $ 4,932 16 % Tax Exempt Loans $ 6,959 22 $ 316 $ 6 - $ 2,248 $ 1 1 % Paycheck Protection Loans $ 71,885 708 $ 102 $ 0 - $ 3,001 $ - 8 % Consumer: Home Equity Lines of Credit $ 36,181 986 $ 37 $ - - $ 504 $ 827 4 % Vehicle 24,196 1,633 15 - - 353 340 3 % Consumer Secured 41,069 1,527 27 20 - 125 577 5 % Consumer Unsecured 20,392 5,026 4 - - 105 287 2 % All Others 2,319 1,006 2 - - 476 33 0 % Total Consumer Loans $ 124,157 10,178 $ 12 $ 2,064 14 % Net deferred loan fees (2,233 ) - - - - Unallocated allowance for loan losses - - - - - Total Loans $ 865,307 14,441 $ 60 $ 13,693 100 % Including the potential effects of the COVID-19 outbreak on the Company’s loan portfolios, the ongoing and dynamic nature of the pandemic and the resultant, potentially severe and long-lasting, economic dislocations, it is difficult to predict the full impact of the COVID-19 outbreak on our business. The extent of such impact will depend on future developments, which are highly uncertain, including when the coronavirus can be controlled and abated and when and how the economy may be reopened. As the result of the COVID-19 pandemic and the related adverse local and national economic consequences, we could be subject to any of the following risks, any of which could have a material, adverse effect on our business, financial condition, liquidity, and results of operations: • Demand for our products and services may decline, making it difficult to grow assets and income; • If the economy is unable to substantially reopen, and high levels of unemployment continue for an extended period of time, loan delinquencies, problem assets, and foreclosures may increase, resulting in increased charges and reduced income; • Collateral for loans, especially real estate, may decline in value, which could cause loan losses to increase; • Our allowance for loan losses may have to be increased if borrowers experience financial difficulties beyond forbearance periods, which will adversely affect our net income; • The net worth and liquidity of loan guarantors may decline, impairing their ability to honor commitments to us; • As the result of the decline in the Federal Reserve Board’s target federal funds rate to near 0%, the yield on our assets may decline to a greater extent than the decline in our cost of interest-bearing liabilities, reducing our net interest margin and spread and reducing net income; • A material decrease in net income or a net loss over several quarters could result in a decrease in the rate of our quarterly cash dividend; • Our cyber security risks are increased as the result of an increase in the number of employees working remotely; • We rely on third party vendors for certain services and the unavailability of a critical service due to the COVID-19 outbreak could have an adverse effect on us; and • Federal Deposit Insurance Corporation premiums may increase if the agency experiences additional resolution costs. Moreover, our future success and profitability substantially depends on the management skills of our executive officers and directors, many of whom have held officer and director positions with us for many years. The unanticipated loss or unavailability of key employees due to the outbreak could harm our ability to operate our business or execute our business strategy. We may not be successful in finding and integrating suitable successors in the event of key employee loss or unavailability. Any one or a combination of the factors identified above could negatively impact our business, financial condition and results of operations and prospects.
