Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	(1) Summary of Significant Accounting Policies Basis of Presentation Within the accompanying unaudited interim consolidated financial statements and related notes to the consolidated financial statements, the June 30, 2023 data was derived from the audited consolidated financial statements and notes of Greene County Bancorp, Inc. (the “Company”) and its wholly owned subsidiaries, The Bank of Greene County (the “Bank”) and the Bank’s wholly owned subsidiaries, Greene County Commercial Bank (the “Commercial Bank”) and Greene Property Holdings, Ltd. The interim consolidated financial statements at and for the three and six months ended December 31, 2023 and 2022 are unaudited. The financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. To the extent that information and notes required by GAAP for complete financial statements are contained in or are consistent with the audited financial statements incorporated by reference to Greene County Bancorp, Inc.’s Annual Report on Form 10-K for the year ended June 30, 2023, such information and notes have not been duplicated herein. In the opinion of management, all adjustments (consisting of only normal recurring items) necessary for a fair presentation of the financial position and results of operations and cash flows at and for the periods presented have been included. Certain previous years’ amounts in the unaudited consolidated financial statements and notes thereto, have been reclassified to conform to the current year’s presentation. All material inter-company accounts and transactions have been eliminated in the consolidation. The results of operations and other data for the three and six months ended December 31, 2023 are not necessarily indicative of results that may be expected for the entire fiscal year ending June 30, 2024. These consolidated financial statements consider events that occurred through the date the consolidated financial statements were issued and should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K. On March 23, 2023, the Company effected a 2-for-1 stock split in the form of a stock dividend on its outstanding shares of common stock. All share and per share data throughout this Quarterly Report on Form 10-Q have been retroactively adjusted to reflect the stock split. The shares of common stock retain a par value of $0.10 per share. Accordingly, an amount equal to the par value of the increased shares resulting from the stock split was reclassified from “Additional paid-in capital” to “Common stock”. Nature of Operations The Company’s primary business is the ownership and operation of its subsidiaries. At December 31, 2023, the Bank has 18 full-service offices and an operations center located in its market area consisting of the Hudson Valley and Capital District Regions of New York State. The Bank is primarily engaged in the business of attracting deposits from the general public in the Bank’s market area, and investing such deposits, together with other sources of funds, in loans and investment securities. The Commercial Bank’s primary business is to attract deposits from, and provide banking services to, local municipalities. Greene Property Holdings, Ltd. was formed as a New York corporation that has elected under the Internal Revenue Code to be a real estate investment trust. Currently, certain mortgages and loan notes held by the Bank are transferred and beneficially owned by Greene Property Holdings, Ltd. The Bank continues to service these loans. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for credit losses on loans and on unfunded commitments. Interest-bearing deposits Included within interest bearing deposits, is $23.1 million of restricted cash. The restriction is due to the surrender of bank owned life insurance during the quarter ended December 31, 2023. Allowance for Credit Losses on Loans The Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments Collateral dependent loans that are on nonaccrual status, with a balance of $250,000 or greater are The loan portfolio is segmented based on the level at which the Company develops and documents a systematic methodology to determine its allowance for credit losses. Management developed the following segments for estimating loss based on type of borrower and collateral which is generally based upon federal call report segmentation and have been combined as needed to ensure loans of similar risk profiles are appropriately pooled: residential real estate, commercial real estate, consumer loan, home equity and commercial loans. Management estimates the allowance for credit losses on loans by using relevant information, from internal and external sources, related to past events, current conditions, and reasonable and supportable forecasts that affect the collectability of loans. Historical loss experience was considered by the Company for estimating expected credit losses and determined the need to use peer data, with similar risk profiles, to develop and calculate the CECL reserve models. Historical credit loss experience for the Company and peer losses by loan segments, provide a foundation for estimating an expected credit loss. The observed credit losses are converted to probability of default (“PD”) rate curves through the use of loss given default (“LGD”) risk factors that converts default rates to estimated loss for each loan segment. This is based on industry-level, observed relationships between the PD and LGD variables for each segment. The historical PD curves correspond to economic variables through historical economic cycles, which establishes a quantitative relationship between forecasted economic conditions and loan performance. Using the historical quantitative relationship between economic conditions and loan performance, management developed a model, using selected external economic forecasts that is highly correlated for each loan segment. These forecasts are then applied over a period that management has determined to be reasonable and supportable. Beyond the period over which management can develop or source a reasonable and supportable forecast, the model will revert to long-term average economic conditions using a straight-line methodology. The allowance for credit losses on loans is measured on a collective basis, when similar risk characteristics are present, with both a quantitative and qualitative analysis that is applied on a quarterly basis. The respective quantitative reserve for each segment is calculated using a PD/LGD modeling methodology, with segment-specific regression models. The discounted cash flows methodology uses expected credit losses estimated over the effective life of each loan by measuring the difference between the net present value of modeled cash flows and amortized cost basis. Contractual cash flows over the contractual life of the loans are the basis for modeled cash flows, adjusted for modeled defaults and expected prepayments and discounted at the loan-level stated interest rate. Management applies a qualitative adjustment for each segment as of the balance sheet date. The qualitative adjustments include limitations inherent in the quantitative model; changes in lending policies and procedures; changes in international, national, regional, and local economic conditions; changes in the nature and volume of the portfolio and terms of loans; the experience, ability and depth of lending management and staff; changes in the volume and severity of past due loans; changes in value of underlying collateral; existence and effect of any concentrations of credit and changes in the levels of such concentrations; and the effect of external factors; such as competition, legal and regulatory requirements. Allowance for Credit Losses on Unfunded Commitments The Company estimates expected credit losses over the contractual period in which the Company has exposure to a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company. The allowance for credit losses on unfunded commitments exposure is recognized in other liabilities and is adjusted as an expense in other noninterest expense. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over the estimated contractual life. The Company considers the following segments of unfunded commitments exposure; home equity line of credits, commercial line of credits, consumer loans, the residential and commercial real estate loans committed but not closed and the unfunded portion of the construction loans. The probable funding amount by segment is multiplied by the respective reserve percentage calculated in the allowance for credit losses on loans to calculate a reserve on unfunded commitments. Allowance for Credit Losses on Securities Held-to-Maturity(“HTM”) The Company is required to utilize the CECL approach to estimate expected credit losses. Management measures expected credit losses on HTM debt securities on a collective basis by major security types that share similar risk characteristics. Management classifies the HTM portfolio into the following major security types: U.S. Treasury securities, state and political subdivisions, mortgage-backed securities-residential, mortgage-backed securities-multi-family, corporate debt securities and other securities. Expected losses are calculated on a pooled basis using a probability of default/loss given default(PD/LGD) model, based on historical credit loss data from a reliable source. Management utilizes municipal and corporate default and loss rates which provides decades of data across all municipal and corporate sectors and geographies. Management may exercise discretion to make adjustments based on environmental factors. The model calculates the expected loss for each security over the contractual life. If the risk of a held-to-maturity debt security no longer matches the collective assessment pool, it is removed and individually assessed for credit deterioration. U.S. Treasury and mortgage-backed securities are issued by U.S. government entities and agencies. These securities are either explicitly and/or implicitly guaranteed by the U.S. government as to timely repayment of principal and interest, are highly rated by major rating agencies, and have a long history of zero credit losses. Therefore, the Company determined a zero credit loss assumption, and did not calculate or record an allowance for credit loss for these securities. Allowance for Credit Losses on Securities Available-for-sale (“AFS”) The credit loss model for AFS debt securities requires credit losses to be presented as an allowance rather than a direct write-down of debt securities. AFS debt securities continue to be recorded at fair value with changes in fair value reflected in other comprehensive income. When the fair value of an AFS debt security falls below the amortized cost basis it is evaluated to determine if any of the decline in value is attributable to credit loss. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. The cash flows are estimated using information relevant to the collectability of the security, including information about past events, current conditions and reasonable and supportable forecasts. Decreases in fair value attributable to credit loss are recorded directly to earnings with a corresponding allowance for credit losses, limited to the amount that the fair value is less than the amortized cost basis. If the credit quality subsequently improves, the allowance is reversed up to a maximum of the previously recorded credit losses. When the Company intends to sell an impaired AFS debt security, or if it is more likely than not that the Company will be required to sell the security prior to recovering the amortized cost basis, the entire fair value adjustment will immediately be recognized in earnings with no corresponding allowance for credit losses. Investments in Federal Home Loan Bank (“FHLB”) stock are required for membership and are carried at cost since there is no market value available. The FHLB New York continues to pay dividends and repurchase stock. As such, the Company has not recognized any credit loss on its holdings of FHLB stock. Accrued Interest Receivable Accrued interest receivable balances are presented separately on the consolidated statements of financial condition and are not included in amortized cost when determining the allowance for credit losses. Accrued interest receivable that is deemed uncollectible is written off timely. For loans, write off typically occurs upon becoming over 90 to 120 days past due and therefore the amount of such write offs are immaterial. Historically, the Company has not experienced uncollectible accrued interest receivable on investment securities. Derivative Instruments The Company enters into interest rate swap agreements that are not designated as hedges for accounting purposes. As the interest rate swap agreements have substantially equivalent and offsetting terms, they do not present any material exposure to the Company’s consolidated statements of income. The Company records its interest rate swap agreements at fair value and is presented on a gross basis within other assets and other liabilities on the consolidated statements of financial condition. Changes in the fair value of assets and liabilities arising from these derivatives are included, net, in other operating income in the consolidated statement of income.

Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	(2) Recent Accounting Pronouncements Recently Adopted Accounting Standards In June 2016, the FASB issued an Update (ASU 2016-13) to its guidance on “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”. ASU 2016-13 requires credit losses on most financial assets measured at amortized cost and certain other instruments to be measured using an expected credit loss model (referred to as the current expected credit loss (CECL) model). Under this model, entities will estimate credit losses over the entire contractual term of the instrument (considering estimated prepayments, but not expected extensions or modifications) from the date of initial recognition of that instrument. The ASU also replaces the current accounting model for purchased credit impaired loans and debt securities. The allowance for credit losses for purchased financial assets with a more-than insignificant amount of credit deterioration since origination (“PCD assets”), should be determined in a similar manner to other financial assets measured on an amortized cost basis. However, upon initial recognition, the allowance for credit losses is added to the purchase price (“gross up approach”) to determine the initial amortized cost basis. The subsequent accounting for PCD financial assets is the same expected loss model described above. Further, the ASU made certain targeted amendments to the existing impairment model for debt securities available-for-sale (AFS). For an AFS debt security for which there is neither the intent nor a more-likely-than-not requirement to sell, an entity will record credit losses as an allowance rather than a write-down of the amortized cost basis. An entity will apply the amendments in this Update through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (that is, a modified-retrospective approach). In November 2018, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, which aligns the implementation date for nonpublic entities’ annual financial statements with the implementation date for their interim financial statements and clarifies the scope of the guidance in the amendments in ASU 2016-13. In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. The amendments to Topic 326 and other topics in ASU 2019-04 include items related to the amendments in Update 2016-13 discussed at the June 2018 and November 2018 Credit Losses TRG meetings. The amendments clarify or address stakeholders’ specific issues about certain aspects of the amendments in Update 2016-13 on a number of different topics, including the following: accrued interest, transfers between classifications or categories for loans and debt securities, recoveries, consideration of prepayments in determining the effective interest rate, consideration of estimated costs to sell when foreclosure is probable, vintage disclosures, line-of-credit arrangements converted to term loans, and contractual extensions and renewals. The effective dates and transition requirements for the amendments related to this Update are the same as the effective dates and transition requirements in Update 2016-13. In November 2019, the FASB issued ASU 2019-11 Codification Improvements to Topic 326 Financial Instruments Credit Losses provides additional clarification to specific issues about certain aspects of the amendments in Update 2016-13 related to measuring the allowance for loan losses under the new guidance . For public business entities that are U.S. Securities and Exchange Commission (SEC) filers, excluding small reporting companies such as the Company, the amendments in this Update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. In November 2019, FASB issued ASU 2019-10, Financial Instruments – Credit Losses which amends the implementation effective date for small reporting companies, such as the Company, and non-public business entities, for fiscal years beginning after December 15, 2022. All entities may adopt the amendments in this Update earlier as of the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company adopted CECL on July 1, 2023 (“Day-one”) using the modified retrospective method for all financial assets measured at amortized cost and off-balance-sheet credit exposures. Results for reporting periods beginning after July 1, 2023 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. The Company recorded a net decrease to retained earnings of $510,000 as of July 1, 2023 for the cumulative effect of adopting ASC 326. The transition adjustment includes a $1.3 million decrease to the allowance for credit losses on loans, a $503,000 increase to the allowance for credit losses on investment securities held-to-maturity, a $1.5 million increase to the allowance for credit losses on unfunded commitment exposures, and a $186,000 impact to the deferred tax asset. Refer to Note 3 Securities and Note 4 Loans and Allowance for Credit Losses on Loans, included in this Form 10-Q for more information. In March 2022, the FASB issued ASU No. 2022-02, amendments related to Troubled Debt Restructurings (TDRs) for all entities after they adopt ASU 2016-13 and amendments related to vintage disclosures that affect public business entities with investments in financing receivables, under Financial Instruments-Credit Losses (Topic 326). The ASU eliminates the guidance on TDRs and requires an evaluation on all loan modifications to determine if they result in a new loan or a continuation of the existing loan. The ASU also requires that entities disclose current-period gross charge-offs by year of origination and eliminates the recognition and measurement guidance for TDRs in Subtopic 310-40. The effective dates for the amendments in this Update are the same as the effective dates in ASU 2016-13. The amendments in this Update should be applied prospectively, except for the transition method related to the recognition and measurement of TDRs. An entity has the option to apply a modified retrospective transition method, resulting in a cumulative-effect adjustment to retained earnings in the period of adoption. The Company adopted this standard on a prospective basis as of July 1, 2023, concurrent with the adoption of ASU 2016-13. In March 2020, the FASB issued an Update (ASU 2020-04), Reference Rate Reform (Topic 848). On January 7, 2021, the FASB issued (ASU 2021-01), which refines the scope of ASC 848 and clarifies some of its guidance. The ASU and related amendments provide temporary optional expedients and exceptions to the existing guidance for applying GAAP to affected contract modifications and hedge accounting relationships in the transition away from the London Interbank Offered Rate (“LIBOR”) or other interbank offered rate on financial reporting. The guidance also allows a one-time election to sell and/or reclassify to AFS or trading HTM debt securities that reference an interest rate affected by reference rate reform. The amendments in this ASU are effective March 12, 2020 through December 31, 2022 and permits relief solely for reference rate reform actions and permits different elections over the effective date for legacy and new activity. The Company adopted the standard during the quarter ended September 30, 2023, and it did not have a material impact on the consolidated financial statements as the Company’s LIBOR exposure was minimal and limited to a couple of participation loans and risk participation agreements. In December 2022, the FASB issued an Update (ASU 2022-06), Reference Rate Reform (Topic 848) Deferral of the Sunset Date of Topic 848. The ASU extends the period of time companies can utilize the reference rate reform relief guidance provided by ASU 2020-04 and ASU 2021-01. The guidance, which was effective upon issuance, defers the sunset date from December 31, 2022 to December 31, 2024, after which companies will no longer be permitted to apply the relief guidance in Topic 848. The adoption did not have a material impact on the consolidated financial statements and related disclosures.

For periods subsequent to adoption, an allowance is calculated under the CECL methodology. The periods prior to adoption did not have an allowance for credit losses under applicable GAAP for those periods. U.S. Treasury and mortgage-backed securities are issued by U.S. government entities and agencies. These securities are either explicitly and/or implicitly guaranteed by the U.S. government as to timely repayment of principal and interest, are highly rated by major rating agencies, and have a long history of zero credit losses. Therefore, the Company determined a zero credit loss assumption, and did not calculate or record an allowance for credit loss for these securities. An allowance for credit losses on investment securities held-to-maturity as of December 31, 2023 has been recorded for certain municipal securities issued by state and political subdivisions and corporate debt securities to account for expected lifetime credit loss using the CECL methodology. The Company’s current policies generally limit securities investments to U.S. Government and securities of government sponsored enterprises, federal funds sold, municipal bonds, corporate debt obligations, subordinated debt of banks and certain mutual funds. In addition, the Company’s policies permit investments in mortgage-backed securities, including securities issued and guaranteed by Fannie Mae, Freddie Mac, and GNMA, and collateralized mortgage obligations issued by these entities. As of December 31, 2023, all mortgage-backed securities including collateralized mortgage obligations were securities of government sponsored enterprises, no private-label mortgage-backed securities or collateralized mortgage obligations were held in the securities portfolio. The Company’s investments in state and political subdivisions securities generally are municipal obligations that are general obligations supported by the general taxing authority of the issuer, and in some cases are insured. The obligations issued by school districts are supported by state aid. Primarily, these investments are issued by municipalities within New York State. The Company’s current securities investment strategy utilizes a risk management approach of diversified investing among three categories: short-, intermediate- and long-term. The emphasis of this approach is to increase overall investment securities yields while managing interest rate risk. The Company will only invest in high quality securities as determined by management’s analysis at the time of purchase. The Company generally does not engage in any derivative or hedging transactions, such as balance sheet interest rate swaps or caps.

During the three and six months ended December 31, 2023, there were no sales of securities and no gains or losses were recogni zed. During the three and six months ended December 31, 2022, a loss of $251,000 was recognized from one sale of an available-for-sale security. The proceeds were used to fund higher yielding loans. The estimated fair values of debt securities at December 31, 2023, by contractual maturity are shown below.

At December 31, 2023 and June 30, 2023, securities with an aggregate fair value of $24.3 million and $20.8 million, respectively, were pledged as collateral for potential borrowings at the Federal Reserve Bank discount window and the Bank Term Funding Program. The Company did not participate in any securities lending programs during the three and six months ended December 31, 2023 or 2022. Federal Home Loan Bank Stock Federal law requires a member institution of the Federal Home Loan Bank (“FHLB”) system to hold stock of its district FHLB according to a predetermined formula. This stock is restricted in that it can only be sold to the FHLB or to another member institution, and all sales of FHLB stock must be at par. As a result of these restrictions, FHLB stock is carried at cost. FHLB stock is held as a long-term investment and its value is determined based on the ultimate recoverability of the par value. Estimated credit loss of this investment is evaluated quarterly and is a matter of judgment that reflects management’s view of the FHLB’s long-term performance, which includes factors such as the following: its operating performance; the severity and duration of declines in the fair value of its net assets related to its capital stock amount; its commitment to make payments required by law or regulation and the level of such payments in relation to its operating performance; the impact of legislative and regulatory changes on the FHLB, and accordingly, on the members of the FHLB; and its liquidity and funding position. After evaluating these considerations, the Company concluded that the par value of its investment in FHLB stock will be recovered and, therefore, no credit loss was recorded during the three and six months ended December 31, 2023 or 2022.

Loans and Allowance for Credit Losses on Loans [Abstract]
Loans and Allowance for Credit Losses on Loans	(4) Loans and Allowanc e The Company adopted ASU 2016-13 (CECL) effective July 1, 2023. The loan segmentation has been redefined under CECL and therefore prior year tables are presented separately. With the adoption of CECL, the Company’s revised loan segments at December 31, 2023 are as follows: (In thousands) December 31, 2023 Residential real estate $ 401,656 Commercial real estate 911,731 Home equity 26,167 Consumer 4,691 Commercial 112,930 Total gross loans (1)(2) 1,457,175 Allowance for credit losses on loans (20,309 ) Loans receivable, net $ 1,436,866 (1) Loan balances include net deferred fees/cost of $54,000 at December 31, 2023. (2) Loan balances exclude accrued interest receivable of $6.4 million at December 31, 2023, which is included in accrued interest receivable in the consolidated statement of financial condition. Nonaccrual Loans Management places loans on nonaccrual status once the loans have become 90 days or more delinquent. A nonaccrual loan is defined as a loan in which collectability is questionable and therefore interest on the loan will no longer be recognized on an accrual basis. A loan is not placed back on accrual status until the borrower has demonstrated the ability and willingness to make timely payments on the loan. A loan does not have to be 90 days delinquent in order to be classified as nonaccrual. Loans on nonaccrual status totaled $5.6 million at December 31, 2023, of which there were two residential loans totaling $449,000 and two commercial real estate loans totaling $1.4 million that were in the process of foreclosure. Included in nonaccrual loans were $1.7 million of loans which were less than 90 days past due at December 31, 2023, but have a recent history of delinquency greater than 90 days past due. These loans will be returned to accrual status once they have demonstrated a history of timely payments. Loans on nonaccrual status totaled $5.5 million at June 30, 2023 of which three residential real estate loans totaling $625,000 and two commercial real estate loans totaling $1.4 million were in the process of foreclosure. Included in nonaccrual loans were $3.1 million of loans which were less than 90 days past due at June 30, 2023, but have a recent history of delinquency greater than 90 days past due. The activity in nonperforming loans during the six months ended, December 31, 2023, included $403,000 in loan repayments, $19,000 in loans returning to performing status, $46,000 in charge-offs or transfers to foreclosed, and $665,000 of loans placed into nonperforming status. The following table sets forth information regarding delinquent and/or nonaccrual loans at December 31, 2023: (In thousands) 30-59 days past due 60-89 days past due 90 days or more past due Total past due Current Total Loans Loans on Non- accrual Residential real estate $ 3,470 $ 609 $ 1,323 $ 5,402 $ 396,254 $ 401,656 $ 2,524 Commercial real estate 1,829 54 1,247 3,130 908,601 911,731 1,682 Home equity 300 35 13 348 25,819 26,167 50 Consumer 13 - - 13 4,678 4,691 - Commercial loans 7 - 1,392 1,399 111,531 112,930 1,392 Total gross loans $ 5,619 $ 698 $ 3,975 $ 10,292 $ 1,446,883 $ 1,457,175 $ 5,648 Allowance for Credit Losses on Loans The Company’s July 1, 2023 adoption of CECL resulted in a significant change to our methodology for estimating the allowance for credit losses. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for credit losses. Such agencies may require the Company to recognize additions to the allowance based on their judgment about information available to them at the time of their examination. The Company charges loans off against the allowance for credit losses when it becomes evident that a loan cannot be collected within a reasonable amount of time, or that it will cost the Company more than it will receive and all possible avenues of repayment have been analyzed, including the potential of future cash flow, the value of the underlying collateral, and strength of any guarantors or co-borrowers. Generally, consumer loans and smaller business loans (not secured by real estate) in excess of 90 days are charged-off against the allowance for credit losses, unless equitable arrangements are made. Included within consumer loan charge-offs and recoveries are deposit accounts that have been overdrawn in excess of 60 days. For loans secured by real estate, a charge-off is recorded when it is determined that the collection of all or a portion of a loan may not be collected and the amount of that loss can be reasonably estimated. The allowance for credit losses is increased by a provision for credit losses (which results in a charge to expense) and recoveries of loans previously charged off, and is reduced by charge-offs. The following tables set forth the activity and allocation of the allowance for credit losses on loans by segment: Activity for the three months ended December 31, 2023 (In thousands) Residential Real Estate Commercial Real Estate Home Equity Consumer Commercial Total Balance at September 30, 2023 $ 3,869 $ 12,356 $ 188 $ 490 $ 3,346 $ 20,249 Charge-offs - - - (154 ) (6 ) (160 ) Recoveries - - - 28 9 37 Provision 141 167 4 122 (251 ) 183 Balance at December 31, 2023 $ 4,010 $ 12,523 $ 192 $ 486 $ 3,098 $ 20,309 Activity for the six months ended December 31, 2023 (In thousands) Residential Real Estate Commercial Real Estate Home Equity Consumer Commercial Total Balance at June 30, 2023 $ 2,794 $ 14,839 $ 46 $ 332 $ 3,201 $ 21,212 Adoption of ASU No. 2016-13 1,182 (2,889 ) 117 137 121 (1,332 ) Charge-offs - - - (276 ) (13 ) (289 ) Recoveries - 1 - 54 18 73 Provision 34 572 29 239 (229 ) 645 Balance at December 31, 2023 $ 4,010 $ 12,523 $ 192 $ 486 $ 3,098 $ 20,309 The allowance for credit losses on unfunded commitments as of December 31, 2023 was $1.6 million. Credit monitoring process Management closely monitors the quality of the loan portfolio and has established a loan review process designed to help grade the quality and profitability of the Company’s loan portfolio. The credit quality grade helps management make a consistent assessment of each loan relationship’s credit risk. Consistent with regulatory guidelines, the Company provides for the classification of loans considered being of lesser quality. Such ratings coincide with the “Substandard,” “Doubtful” and “Loss” classifications used by federal regulators in their examination of financial institutions. For the commercial real estate and commercial loans, generally, an asset is considered Substandard if it is inadequately protected by the current net worth and paying capacity of the obligors and/or the collateral pledged. Substandard assets include those characterized by the distinct possibility that the insured financial institution will sustain some loss if the deficiencies are not corrected. Assets classified as Doubtful have all the weaknesses inherent in assets classified Substandard with the added characteristic that the weaknesses present make collection or liquidation in full, on the basis of currently existing facts, highly questionable and improbable. Assets classified as Loss are those considered uncollectible and of such little value that their continuance as assets without the establishment of a full loss reserve and/or charge-off is not warranted. Assets that do not currently expose the Company to sufficient risk to warrant classification in one of the aforementioned categories but otherwise possess weaknesses are designated “Special Mention.” Residential real estate, home equity and consumer loans are graded as either nonperforming or performing. Nonperforming loans are loans that are generally over 90 days past due or on nonaccrual status. Residential mortgage loans, including home equity loans, which are collateralized by residences are generally made in amounts up to 85.0% of the appraised value of the property. In the event of default by the borrower the Company will acquire and liquidate the underlying collateral. By originating the loan at a loan-to-value ratio of 85.0% or less, the Company limits its risk of loss in the event of default. However, the market values of the collateral may be adversely impacted by declines in the economy. Home equity loans may have an additional inherent risk if the Company does not hold the first mortgage. The Company may stand in a secondary position in the event of collateral liquidation resulting in a greater chance of insufficiency to meet all obligations. Construction loan repayments to a degree, are dependent upon the successful and timely completion of the construction of the subject property within specified cost limits. The Company completes inspections during the construction phase prior to any disbursements. The Company limits its risk during the construction as disbursements are not made until the required work for each advance has been completed. Construction delays may further impair the borrower’s ability to repay the loan. Loans collateralized by commercial real estate, and multi-family dwellings, such as apartment buildings generally are larger than residential loans and involve a greater degree of risk. Commercial real estate loans often involve large loan balances to single borrowers or groups of related borrowers. Payments on these loans depend to a large degree on the results of operations and management of the properties or underlying businesses, and may be affected to a greater extent by adverse conditions in the real estate market or the economy in general. Accordingly, the nature of commercial real estate loans makes them more difficult for management to monitor and evaluate. The Company has formed relationships with other community banks within our region to participate in larger commercial loan relationships. These types of loans are generally considered to be riskier due to the size and complexity of the loan relationship. By entering into a participation agreement with the other bank, the Company can obtain the loan relationship while limiting its exposure to credit loss. Management completes its due diligence in underwriting these loans and monitors the servicing of these loans. Consumer loans generally have shorter terms and higher interest rates than residential mortgage loans. In addition, consumer loans expand the products and services offered by the Company to better meet the financial services needs of its customers. Consumer loans generally involve greater credit risk than residential mortgage loans because of the difference in the nature of the underlying collateral. Repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment of the outstanding loan balance because of the greater likelihood of damage, loss or depreciation in the underlying collateral. The remaining deficiency often does not warrant further substantial collection efforts against the borrower beyond obtaining a deficiency judgment. In addition, consumer loan collections depend on the borrower’s personal financial stability. Furthermore, the application of various federal and state laws, including federal and state bankruptcy and insolvency laws, may limit the amount that can be recovered on such loans. Commercial lending involves risks that are different from those associated with residential and commercial real estate mortgage lending. Real estate lending is generally considered to be collateral-based, with loan amounts based on fixed loan-to-collateral values, and liquidation of the underlying real estate collateral is viewed as the primary source of repayment in the event of borrower default. Although commercial loans may be collateralized by equipment or other business assets, the liquidation of collateral in the event of a borrower default is often an insufficient source of repayment because equipment and other business assets may be obsolete or of limited use, among other things. Accordingly, the repayment of a commercial loan depends primarily on the creditworthiness of the borrower (and any guarantors), while liquidation of collateral is a secondary and often insufficient source of repayment. The Company has formed relationships with other community banks within our region to participate in larger commercial loan relationships. These types of loans are generally considered to be riskier due to the size and complexity of the loan relationship. By entering into a participation agreement with the other bank, the Company can obtain the loan relationship while limiting its exposure to credit loss. Management completes its due diligence in underwriting these loans and monitors the servicing of these loans.

Individually Evaluated Loans As of December 31, 2023, collateral dependent loans evaluated individually had an amortized cost basis of $5.8 million, with an allowance for credit losses on loans of $2.0 million. Loan Modifications to Borrowers Experiencing Financial Difficulties As mentioned in Note 2 Recent Accounting Pronouncements, the Company’s July 1, 2023 adoption of ASU 2022-02 eliminates the recognition and measurement of TDRs. Upon adoption of this guidance, the Company will no longer recognize an allowance for credit losses for the economic concession granted to a borrower for changes in the timing and amount of contractual cash flows when a loan is restructured. The adoption of ASU 2022-02 results in a change to reporting for loan modifications to borrowers experiencing financial difficulties. With the adoption of ASU 2022-02 these modifications require enhanced reporting on the type of modifications granted and the financial magnitude of the concessions granted. When the Company modifies a loan with financial difficulty, such modifications generally include one or a combination of the following: an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk; a change in scheduled payment amount; or principal forgiveness. There were no loans during the six months ended December 31, 2023 that were modified to borrowers experiencing financial difficulty since the adoption of ASU 2022-02 effective July 1, 2023. Prior to the adoption of ASU 2016-13 (CECL) Prior to July 1, 2023, the Company calculated the allowance for loan losses using the incurred loss methodology.

Fair Value Measurements and Fair Value of Financial Instruments [Abstract]
Fair Value Measurements and Fair Value of Financial Instruments	(5) Fair Value Measurements and Fair Value of Financial Instruments 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 sale transaction on the dates indicated. The estimated fair value amounts have been measured as of December 31, 2023 and June 30, 2023 and have not been re-evaluated or updated for purposes of these consolidated 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. 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 FASB ASC Topic on “ Fair Value Measurement” Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2: Quoted prices for similar assets or liabilities in active markets, quoted prices in markets that are not active, or inputs that are observable either directly or indirectly, for substantially the full term of the asset or liability. 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. For assets measured at fair value on a recurring basis, the fair value measurements by level within the fair value hierarchy used are as follows: Fair Value Measurements Using Quoted Prices In Active Markets For Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs (In thousands) December 31, 2023 (Level 1) (Level 2) (Level 3) Assets: U.S. Government sponsored enterprises $ 11,059 $ - $ 11,059 $ - U.S. Treasury securities 16,717 - 16,717 - State and political subdivisions 163,834 - 163,834 - Mortgage-backed securities-residential 24,385 - 24,385 - Mortgage-backed securities-multi-family 73,248 - 73,248 - Corporate debt securities 18,566 - 18,566 - Securities available-for-sale 307,809 - 307,809 - Equity securities 325 325 - - Total securities measured at fair value $ 308,134 $ 325 $ 307,809 $ - Fair Value Measurements Using Quoted Prices In Active Markets For Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs (In thousands) June 30, 2023 (Level 1) (Level 2) (Level 3) Assets: U.S. Government sponsored enterprises $ 10,823 $ - $ 10,823 $ - U.S. Treasury securities 16,500 - 16,500 - State and political subdivisions 138,011 - 138,011 - Mortgage-backed securities-residential 25,601 - 25,601 - Mortgage-backed securities-multi-family 72,086 - 72,086 - Corporate debt securities 18,112 - 18,112 - Securities available-for-sale 281,133 - 281,133 - Equity securities 306 306 - - Total securities measured at fair value $ 281,439 $ 306 $ 281,133 $ - Certain investments that are actively traded and have quoted market prices have been classified as Level 1 valuations. Other available-for-sale investment securities have been valued by reference to prices for similar securities or through model-based techniques in which all significant inputs are observable and, therefore, such valuations have been classified as Level 2. In addition to disclosures of the fair value of assets on a recurring basis, FASB ASC Topic on “ Fair Value Measurement 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 credit losses. Values are derived from appraisals, similar to collateral dependent loans evaluated individually, of underlying collateral. 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 may modify the appraised values, for qualitative factors such as economic conditions and estimated liquidation expenses ranging from 10% to 60%. Such modifications to the appraised values could result in lower valuations of such collateral. Based on the valuation techniques used, the fair value measurements for foreclosed real estate are classified as Level 3. December 31, 2023 June 30, 2023 (In thousands) Fair Value Hierarchy Carrying Amount Estimated Fair Value Carrying Amount Estimated Fair Value Collateral dependent evaluated loans 3 $ 5,772 $ 3,774 $ 7,578 $ 5,565 Foreclosed real estate 3 $ 302 $ 302 $ 302 $ 302 The carrying amounts reported in the statements of financial condition for total cash and cash equivalents, long term certificates of deposit, accrued interest receivable and accrued interest payable approximate their fair values. Fair values of securities are based on quoted market prices (Level 1), where available, or matrix pricing (Level 2), which is a mathematical technique, used widely in the industry to value debt securities without relying exclusively on quoted market prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted prices. The carrying amount of Federal Home Loan Bank stock approximates fair value due to its restricted nature. The fair values for loans are measured using the “exit price” notion which is a reasonable estimate of what another party might pay in an orderly transaction. Fair values for variable rate loans that reprice frequently, with no significant credit risk, are based on carrying value. Fair values for fixed rate loans are estimated using discounted cash flows and interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. Fair values disclosed for demand and savings deposits are equal to carrying amounts at the reporting date. The carrying amounts for variable rate money market deposits approximate fair values at the reporting date. Fair values for long term certificates of deposit are estimated using discounted cash flows and interest rates currently being offered in the market on similar certificates. Fair value for Federal Home Loan Bank long term borrowings are estimated using discounted cash flows and interest rates currently being offered on similar borrowings. The carrying value of short-term Federal Home Loan Bank borrowings approximates its fair value.

Derivative Instruments [Abstract]
Derivative Instruments	(6) Derivative Instruments The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, primarily by managing the amount, sources and duration of its assets and liabilities. The Company has interest rate derivatives that result from a service provided to certain qualifying customers and, therefore, are not used to manage interest rate risk in the Company’s assets or liabilities. The Company manages a matched book with respect to its derivative instruments in order to minimize its net risk exposure resulting from such transactions. Derivatives Not Designated as Hedging Instruments The Company enters into interest rate swap agreements with its commercial customers to provide them with a long-term fixed rate, while simultaneously entering into offsetting interest rate swap agreements with a counterparty to swap the fixed rate to a variable rate to manage interest rate exposure. These interest rate swap agreements are not designated as hedges for accounting purposes. As the interest rate swap agreements have substantially equivalent and offsetting terms, they do not present any material exposure to the Company’s consolidated statements of income. The Company records its interest rate swap agreements at fair value and are presented within other assets and other liabilities on the consolidated statements of financial condition. Changes in the fair value of assets and liabilities arising from these derivatives are included, net, in other operating income in the consolidated statements of income. Under terms of the agreements with the third-party counterparties, the Company provides cash collateral to the counterparty, when required, for the initial trade. Subsequent to the trade, the margin is exchanged in either direction, based upon the estimated fair value of the underlying contracts. Cash collateral represents the amount that is exchanged under master netting agreements that allows the Company to offset the derivative position with the related collateral. The notional amount of the interest rate swaps does not represent amounts exchanged by the parties. The amount exchanged is determined by reference to the notional amount and the other terms of the individual interest rate swap agreements. The following table present the notional amount and fair values of interest rate derivative positions: At December 31, 2023 Asset Derivatives Liability Derivatives ( In thousands Statement of Financial Condition Location Notional Amount Fair Value Statement of Financial Condition Location Notional Amount Fair Value Interest rate derivatives Other Assets $ 25,680 $ 1,156 Other Liabilities $ 25,680 $ 1,156 Less cash collateral - Other Liabilities (1,160 ) Total after netting $ 1,156 $ (4 ) There were no interest rate swap agreements for the Company at June 30, 2023. Risk Participation Agreements Risk participation agreements (“RPAs”) are guarantees issued by the Company to other parties for a fee, whereby the Company agrees to participate in the credit risk of a derivative customer of the other party. Under the terms of these agreements, the “participating bank” receives a fee from the “lead bank” in exchange for the guarantee of reimbursement if the customer defaults on an interest rate swap. The interest rate swap is transacted such that any and all exchanges of interest payments (favorable and unfavorable) are made between the lead bank and the customer. In the event that an early termination of the swap occurs and the customer is unable to make a required close out payment, the participating bank assumes that obligation and is required to make this payment. RPAs in which the Company acts as the lead bank are referred to as “participations-out,” in reference to the credit risk associated with the customer derivatives being transferred out of the Company. Participations-out generally occur concurrently with the sale of new customer derivatives. The Company’s exposure was reduced due to participations-outs, at December 31, 2023 by $344,000, with a notional amount of $8.0 million. There were no participations-outs at June 30, 2023. RPAs in which the Company acts as the participating bank are referred to as “participations-in,” in reference to the credit risk associated with the counterparty’s derivatives being assumed by the Company. The Company’s maximum credit exposure is based on its proportionate share of the settlement amount of the referenced interest rate swap. Settlement amounts are generally calculated based on the fair value of the swap plus outstanding accrued interest receivables from the customer. The credit exposure associated with risk participations-ins was $1.0 million and zero as of December 31, 2023 and June 30, 2023, respectively. The RPAs participations-ins are spread out over four financial institution counterparties and terms range between 4 to 13 years. At December 31, 2023 and June 30, 2023, the Company held RPAs with a notional amount of $110.2 million and $82.0 million, respectively.

Earnings Per Share [Abstract]
Earnings Per Share	(7) Earnings Per Share Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed in a manner similar to that of basic earnings per share except that the weighted-average number of common shares outstanding is increased to include the number of incremental common shares that would have been outstanding under the treasury stock method if all potentially dilutive common shares (such as stock options) issued became vested during the period. There were no dilutive or anti-dilutive securities or contracts outstanding during the three and six months ended December 31, 2023 and 2022. On March 23, 2023, the Company effected a 2-for-1 stock split in the form of a stock dividend on its outstanding shares of common stock. Weighted-average number of shares and earnings per share have been retroactively adjusted in all periods presented as if the new shares had been issued and outstanding at the same time as the original shares.

Commitments and Contingent Liabilities [Abstract]
Commitments and Contingent Liabilities	(13) Commitments and Contingent Liabilities Credit-Related Financial Instruments In the normal course of business, the Company offers financial instruments with off-balance sheet risk to meet the financing needs of its customers. These transactions include commitments to extend credit, standby letters of credit, and lines of credit, which involve, to varying degrees, elements of credit risk. The table summarizes the outstanding amounts of credit-related financial instruments with off-balance sheet risk: (In thousands) December 31, 2023 June 30, 2023 Unfunded loan commitments $ 127,098 $ 124,498 Unused lines of credit 93,738 94,898 Standby letters of credit 179 179 Total credit-related financial instruments with off-balance sheet risk $ 221,015 $ 219,575 The Company enters into contractual commitments to extend credit to its customers in the form of loan commitments and lines of credit, generally with fixed expiration dates and other termination clauses, and may require payment of a fee. Substantially all of the Company’s commitments to extend credit are contingent upon its customers maintaining specific credit standards at the time of loan funding, and are often secured by real estate collateral. Since the majority of the Company’s commitments typically expire without being funded, the total contractual amount does not necessarily represent the Company’s future payment requirements. The Company evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral, if any, required upon an extension of credit is based on management’s evaluation of customer credit. Commitments to extend mortgage credit are primarily collateralized by first liens on real estate. Collateral on extensions of commercial lines of credit vary but may include accounts receivable, inventory, property, plant and equipment, and income producing commercial property. Allowance for Credit Losses on Unfunded Commitments The Company estimates expected credit losses over the contractual period in which the Company has exposure to a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company. The allowance for credit losses on unfunded commitments exposure is recognized in other liabilities and is adjusted as an expense in other noninterest expense. At December 31, 2023, the allowance for credit losses on unfunded commitments totaled $1.6 million. Litigation The Company and its subsidiaries are, from time to time, parties to various legal proceedings arising out of their businesses. Except as noted below, management believes there are no such legal proceedings pending or threatened against the Company or its subsidiaries, if determined adversely, would have a material adverse effect on the business, consolidated financial condition, results of operations or cash flows of the Company or any of its subsidiaries. On April 26, 2022, Andrew Broockmann, a customer of The Bank of Greene County (the “Bank”), filed a putative class action complaint against the Bank in the United States District Court for the Northern District of New York. The complaint alleges that the Bank improperly assessed overdraft fees on debit-card transactions that were authorized on a positive account balance but settled on a negative balance. Mr. Broockmann, on behalf of the putative class, seeks compensatory damages, punitive damages, enjoinment of the conduct complained of, and costs and fees. The complaint is similar to complaints filed against other financial institutions pertaining to overdraft fees. The Bank denies that it improperly assessed overdraft fees or breached any agreement with Mr. Broockmann or with members of the putative class. On February 28, 2023, the parties entered into a settlement agreement which contemplates, among other things, that the Bank will (a) pay a cash payment of $1.15 million, (b) forgive, waive, and not collect an additional $64,500 in uncollected overdraft fees, and (c) cease collecting certain types of overdraft fees. On approval of the class action settlement and closed the case. The Company established a settlement fund of $1.15 The settlement fund has been substantially distributed to class members. A final report of class-member payments must be filed with Court by May 13, 2024. Any residual amounts in the settlement fund not distributed will thereafter be paid to a local charity .

Summary of Significant Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Within the accompanying unaudited interim consolidated financial statements and related notes to the consolidated financial statements, the June 30, 2023 data was derived from the audited consolidated financial statements and notes of Greene County Bancorp, Inc. (the “Company”) and its wholly owned subsidiaries, The Bank of Greene County (the “Bank”) and the Bank’s wholly owned subsidiaries, Greene County Commercial Bank (the “Commercial Bank”) and Greene Property Holdings, Ltd. The interim consolidated financial statements at and for the three and six months ended December 31, 2023 and 2022 are unaudited. The financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. To the extent that information and notes required by GAAP for complete financial statements are contained in or are consistent with the audited financial statements incorporated by reference to Greene County Bancorp, Inc.’s Annual Report on Form 10-K for the year ended June 30, 2023, such information and notes have not been duplicated herein. In the opinion of management, all adjustments (consisting of only normal recurring items) necessary for a fair presentation of the financial position and results of operations and cash flows at and for the periods presented have been included. Certain previous years’ amounts in the unaudited consolidated financial statements and notes thereto, have been reclassified to conform to the current year’s presentation. All material inter-company accounts and transactions have been eliminated in the consolidation. The results of operations and other data for the three and six months ended December 31, 2023 are not necessarily indicative of results that may be expected for the entire fiscal year ending June 30, 2024. These consolidated financial statements consider events that occurred through the date the consolidated financial statements were issued and should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K. On March 23, 2023, the Company effected a 2-for-1 stock split in the form of a stock dividend on its outstanding shares of common stock. All share and per share data throughout this Quarterly Report on Form 10-Q have been retroactively adjusted to reflect the stock split. The shares of common stock retain a par value of $0.10 per share. Accordingly, an amount equal to the par value of the increased shares resulting from the stock split was reclassified from “Additional paid-in capital” to “Common stock”.
Nature of Operations	Nature of Operations The Company’s primary business is the ownership and operation of its subsidiaries. At December 31, 2023, the Bank has 18 full-service offices and an operations center located in its market area consisting of the Hudson Valley and Capital District Regions of New York State. The Bank is primarily engaged in the business of attracting deposits from the general public in the Bank’s market area, and investing such deposits, together with other sources of funds, in loans and investment securities. The Commercial Bank’s primary business is to attract deposits from, and provide banking services to, local municipalities. Greene Property Holdings, Ltd. was formed as a New York corporation that has elected under the Internal Revenue Code to be a real estate investment trust. Currently, certain mortgages and loan notes held by the Bank are transferred and beneficially owned by Greene Property Holdings, Ltd. The Bank continues to service these loans.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for credit losses on loans and on unfunded commitments.
Interest-bearing Deposits	Interest-bearing deposits Included within interest bearing deposits, is $23.1 million of restricted cash. The restriction is due to the surrender of bank owned life insurance during the quarter ended December 31, 2023.
Allowance for Credit Losses on Loans	Allowance for Credit Losses on Loans The Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments Collateral dependent loans that are on nonaccrual status, with a balance of $250,000 or greater are The loan portfolio is segmented based on the level at which the Company develops and documents a systematic methodology to determine its allowance for credit losses. Management developed the following segments for estimating loss based on type of borrower and collateral which is generally based upon federal call report segmentation and have been combined as needed to ensure loans of similar risk profiles are appropriately pooled: residential real estate, commercial real estate, consumer loan, home equity and commercial loans. Management estimates the allowance for credit losses on loans by using relevant information, from internal and external sources, related to past events, current conditions, and reasonable and supportable forecasts that affect the collectability of loans. Historical loss experience was considered by the Company for estimating expected credit losses and determined the need to use peer data, with similar risk profiles, to develop and calculate the CECL reserve models. Historical credit loss experience for the Company and peer losses by loan segments, provide a foundation for estimating an expected credit loss. The observed credit losses are converted to probability of default (“PD”) rate curves through the use of loss given default (“LGD”) risk factors that converts default rates to estimated loss for each loan segment. This is based on industry-level, observed relationships between the PD and LGD variables for each segment. The historical PD curves correspond to economic variables through historical economic cycles, which establishes a quantitative relationship between forecasted economic conditions and loan performance. Using the historical quantitative relationship between economic conditions and loan performance, management developed a model, using selected external economic forecasts that is highly correlated for each loan segment. These forecasts are then applied over a period that management has determined to be reasonable and supportable. Beyond the period over which management can develop or source a reasonable and supportable forecast, the model will revert to long-term average economic conditions using a straight-line methodology. The allowance for credit losses on loans is measured on a collective basis, when similar risk characteristics are present, with both a quantitative and qualitative analysis that is applied on a quarterly basis. The respective quantitative reserve for each segment is calculated using a PD/LGD modeling methodology, with segment-specific regression models. The discounted cash flows methodology uses expected credit losses estimated over the effective life of each loan by measuring the difference between the net present value of modeled cash flows and amortized cost basis. Contractual cash flows over the contractual life of the loans are the basis for modeled cash flows, adjusted for modeled defaults and expected prepayments and discounted at the loan-level stated interest rate. Management applies a qualitative adjustment for each segment as of the balance sheet date. The qualitative adjustments include limitations inherent in the quantitative model; changes in lending policies and procedures; changes in international, national, regional, and local economic conditions; changes in the nature and volume of the portfolio and terms of loans; the experience, ability and depth of lending management and staff; changes in the volume and severity of past due loans; changes in value of underlying collateral; existence and effect of any concentrations of credit and changes in the levels of such concentrations; and the effect of external factors; such as competition, legal and regulatory requirements.
Allowance for Credit Losses on Unfunded Commitments	Allowance for Credit Losses on Unfunded Commitments The Company estimates expected credit losses over the contractual period in which the Company has exposure to a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company. The allowance for credit losses on unfunded commitments exposure is recognized in other liabilities and is adjusted as an expense in other noninterest expense. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over the estimated contractual life. The Company considers the following segments of unfunded commitments exposure; home equity line of credits, commercial line of credits, consumer loans, the residential and commercial real estate loans committed but not closed and the unfunded portion of the construction loans. The probable funding amount by segment is multiplied by the respective reserve percentage calculated in the allowance for credit losses on loans to calculate a reserve on unfunded commitments.
Allowance for Credit Losses on Securities Held-to-Maturity	Allowance for Credit Losses on Securities Held-to-Maturity(“HTM”) The Company is required to utilize the CECL approach to estimate expected credit losses. Management measures expected credit losses on HTM debt securities on a collective basis by major security types that share similar risk characteristics. Management classifies the HTM portfolio into the following major security types: U.S. Treasury securities, state and political subdivisions, mortgage-backed securities-residential, mortgage-backed securities-multi-family, corporate debt securities and other securities. Expected losses are calculated on a pooled basis using a probability of default/loss given default(PD/LGD) model, based on historical credit loss data from a reliable source. Management utilizes municipal and corporate default and loss rates which provides decades of data across all municipal and corporate sectors and geographies. Management may exercise discretion to make adjustments based on environmental factors. The model calculates the expected loss for each security over the contractual life. If the risk of a held-to-maturity debt security no longer matches the collective assessment pool, it is removed and individually assessed for credit deterioration. U.S. Treasury and mortgage-backed securities are issued by U.S. government entities and agencies. These securities are either explicitly and/or implicitly guaranteed by the U.S. government as to timely repayment of principal and interest, are highly rated by major rating agencies, and have a long history of zero credit losses. Therefore, the Company determined a zero credit loss assumption, and did not calculate or record an allowance for credit loss for these securities.
Allowance for Credit Losses on Securities Available-for-sale	Allowance for Credit Losses on Securities Available-for-sale (“AFS”) The credit loss model for AFS debt securities requires credit losses to be presented as an allowance rather than a direct write-down of debt securities. AFS debt securities continue to be recorded at fair value with changes in fair value reflected in other comprehensive income. When the fair value of an AFS debt security falls below the amortized cost basis it is evaluated to determine if any of the decline in value is attributable to credit loss. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. The cash flows are estimated using information relevant to the collectability of the security, including information about past events, current conditions and reasonable and supportable forecasts. Decreases in fair value attributable to credit loss are recorded directly to earnings with a corresponding allowance for credit losses, limited to the amount that the fair value is less than the amortized cost basis. If the credit quality subsequently improves, the allowance is reversed up to a maximum of the previously recorded credit losses. When the Company intends to sell an impaired AFS debt security, or if it is more likely than not that the Company will be required to sell the security prior to recovering the amortized cost basis, the entire fair value adjustment will immediately be recognized in earnings with no corresponding allowance for credit losses. Investments in Federal Home Loan Bank (“FHLB”) stock are required for membership and are carried at cost since there is no market value available. The FHLB New York continues to pay dividends and repurchase stock. As such, the Company has not recognized any credit loss on its holdings of FHLB stock.
Accrued Interest Receivable	Accrued Interest Receivable Accrued interest receivable balances are presented separately on the consolidated statements of financial condition and are not included in amortized cost when determining the allowance for credit losses. Accrued interest receivable that is deemed uncollectible is written off timely. For loans, write off typically occurs upon becoming over 90 to 120 days past due and therefore the amount of such write offs are immaterial. Historically, the Company has not experienced uncollectible accrued interest receivable on investment securities.
Derivative Instruments	Derivative Instruments The Company enters into interest rate swap agreements that are not designated as hedges for accounting purposes. As the interest rate swap agreements have substantially equivalent and offsetting terms, they do not present any material exposure to the Company’s consolidated statements of income. The Company records its interest rate swap agreements at fair value and is presented on a gross basis within other assets and other liabilities on the consolidated statements of financial condition. Changes in the fair value of assets and liabilities arising from these derivatives are included, net, in other operating income in the consolidated statement of income.

Recent Accounting Pronouncements [Abstract]
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards In June 2016, the FASB issued an Update (ASU 2016-13) to its guidance on “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”. ASU 2016-13 requires credit losses on most financial assets measured at amortized cost and certain other instruments to be measured using an expected credit loss model (referred to as the current expected credit loss (CECL) model). Under this model, entities will estimate credit losses over the entire contractual term of the instrument (considering estimated prepayments, but not expected extensions or modifications) from the date of initial recognition of that instrument. The ASU also replaces the current accounting model for purchased credit impaired loans and debt securities. The allowance for credit losses for purchased financial assets with a more-than insignificant amount of credit deterioration since origination (“PCD assets”), should be determined in a similar manner to other financial assets measured on an amortized cost basis. However, upon initial recognition, the allowance for credit losses is added to the purchase price (“gross up approach”) to determine the initial amortized cost basis. The subsequent accounting for PCD financial assets is the same expected loss model described above. Further, the ASU made certain targeted amendments to the existing impairment model for debt securities available-for-sale (AFS). For an AFS debt security for which there is neither the intent nor a more-likely-than-not requirement to sell, an entity will record credit losses as an allowance rather than a write-down of the amortized cost basis. An entity will apply the amendments in this Update through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (that is, a modified-retrospective approach). In November 2018, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, which aligns the implementation date for nonpublic entities’ annual financial statements with the implementation date for their interim financial statements and clarifies the scope of the guidance in the amendments in ASU 2016-13. In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. The amendments to Topic 326 and other topics in ASU 2019-04 include items related to the amendments in Update 2016-13 discussed at the June 2018 and November 2018 Credit Losses TRG meetings. The amendments clarify or address stakeholders’ specific issues about certain aspects of the amendments in Update 2016-13 on a number of different topics, including the following: accrued interest, transfers between classifications or categories for loans and debt securities, recoveries, consideration of prepayments in determining the effective interest rate, consideration of estimated costs to sell when foreclosure is probable, vintage disclosures, line-of-credit arrangements converted to term loans, and contractual extensions and renewals. The effective dates and transition requirements for the amendments related to this Update are the same as the effective dates and transition requirements in Update 2016-13. In November 2019, the FASB issued ASU 2019-11 Codification Improvements to Topic 326 Financial Instruments Credit Losses provides additional clarification to specific issues about certain aspects of the amendments in Update 2016-13 related to measuring the allowance for loan losses under the new guidance . For public business entities that are U.S. Securities and Exchange Commission (SEC) filers, excluding small reporting companies such as the Company, the amendments in this Update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. In November 2019, FASB issued ASU 2019-10, Financial Instruments – Credit Losses which amends the implementation effective date for small reporting companies, such as the Company, and non-public business entities, for fiscal years beginning after December 15, 2022. All entities may adopt the amendments in this Update earlier as of the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company adopted CECL on July 1, 2023 (“Day-one”) using the modified retrospective method for all financial assets measured at amortized cost and off-balance-sheet credit exposures. Results for reporting periods beginning after July 1, 2023 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. The Company recorded a net decrease to retained earnings of $510,000 as of July 1, 2023 for the cumulative effect of adopting ASC 326. The transition adjustment includes a $1.3 million decrease to the allowance for credit losses on loans, a $503,000 increase to the allowance for credit losses on investment securities held-to-maturity, a $1.5 million increase to the allowance for credit losses on unfunded commitment exposures, and a $186,000 impact to the deferred tax asset. Refer to Note 3 Securities and Note 4 Loans and Allowance for Credit Losses on Loans, included in this Form 10-Q for more information. In March 2022, the FASB issued ASU No. 2022-02, amendments related to Troubled Debt Restructurings (TDRs) for all entities after they adopt ASU 2016-13 and amendments related to vintage disclosures that affect public business entities with investments in financing receivables, under Financial Instruments-Credit Losses (Topic 326). The ASU eliminates the guidance on TDRs and requires an evaluation on all loan modifications to determine if they result in a new loan or a continuation of the existing loan. The ASU also requires that entities disclose current-period gross charge-offs by year of origination and eliminates the recognition and measurement guidance for TDRs in Subtopic 310-40. The effective dates for the amendments in this Update are the same as the effective dates in ASU 2016-13. The amendments in this Update should be applied prospectively, except for the transition method related to the recognition and measurement of TDRs. An entity has the option to apply a modified retrospective transition method, resulting in a cumulative-effect adjustment to retained earnings in the period of adoption. The Company adopted this standard on a prospective basis as of July 1, 2023, concurrent with the adoption of ASU 2016-13. In March 2020, the FASB issued an Update (ASU 2020-04), Reference Rate Reform (Topic 848). On January 7, 2021, the FASB issued (ASU 2021-01), which refines the scope of ASC 848 and clarifies some of its guidance. The ASU and related amendments provide temporary optional expedients and exceptions to the existing guidance for applying GAAP to affected contract modifications and hedge accounting relationships in the transition away from the London Interbank Offered Rate (“LIBOR”) or other interbank offered rate on financial reporting. The guidance also allows a one-time election to sell and/or reclassify to AFS or trading HTM debt securities that reference an interest rate affected by reference rate reform. The amendments in this ASU are effective March 12, 2020 through December 31, 2022 and permits relief solely for reference rate reform actions and permits different elections over the effective date for legacy and new activity. The Company adopted the standard during the quarter ended September 30, 2023, and it did not have a material impact on the consolidated financial statements as the Company’s LIBOR exposure was minimal and limited to a couple of participation loans and risk participation agreements. In December 2022, the FASB issued an Update (ASU 2022-06), Reference Rate Reform (Topic 848) Deferral of the Sunset Date of Topic 848. The ASU extends the period of time companies can utilize the reference rate reform relief guidance provided by ASU 2020-04 and ASU 2021-01. The guidance, which was effective upon issuance, defers the sunset date from December 31, 2022 to December 31, 2024, after which companies will no longer be permitted to apply the relief guidance in Topic 848. The adoption did not have a material impact on the consolidated financial statements and related disclosures.

Federal Home Loan Bank Stock	Federal Home Loan Bank Stock Federal law requires a member institution of the Federal Home Loan Bank (“FHLB”) system to hold stock of its district FHLB according to a predetermined formula. This stock is restricted in that it can only be sold to the FHLB or to another member institution, and all sales of FHLB stock must be at par. As a result of these restrictions, FHLB stock is carried at cost. FHLB stock is held as a long-term investment and its value is determined based on the ultimate recoverability of the par value. Estimated credit loss of this investment is evaluated quarterly and is a matter of judgment that reflects management’s view of the FHLB’s long-term performance, which includes factors such as the following: its operating performance; the severity and duration of declines in the fair value of its net assets related to its capital stock amount; its commitment to make payments required by law or regulation and the level of such payments in relation to its operating performance; the impact of legislative and regulatory changes on the FHLB, and accordingly, on the members of the FHLB; and its liquidity and funding position. After evaluating these considerations, the Company concluded that the par value of its investment in FHLB stock will be recovered and, therefore, no credit loss was recorded during the three and six months ended December 31, 2023 or 2022.

Fair Value Measurements for Collateral Dependent Evaluated Loans and Foreclosed Real Estate	In addition to disclosures of the fair value of assets on a recurring basis, FASB ASC Topic on “ Fair Value Measurement 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 credit losses. Values are derived from appraisals, similar to collateral dependent loans evaluated individually, of underlying collateral. 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 may modify the appraised values, for qualitative factors such as economic conditions and estimated liquidation expenses ranging from 10% to 60%. Such modifications to the appraised values could result in lower valuations of such collateral. Based on the valuation techniques used, the fair value measurements for foreclosed real estate are classified as Level 3.
