Nature of Operations
Nature of Operations	Note 1 - NATURE OF OPERATIONS Gouverneur Bancorp, Inc. (the “Company”) is a savings and loan holding company. Its only subsidiary is Gouverneur Savings and Loan Association (the “Bank”). On March 23, 1999, the Bank reorganized into the mutual holding company form of organization as a wholly-owned subsidiary of Bancorp, a mid-tier stock holding company that became the majority-owned subsidiary of Cambray Mutual Holding Company. Cambray Mutual Holding Company, (the “MHC”), a mutual holding company whose activity is not included in the accompanying consolidated financial statements, owns 64.55% of the outstanding common stock of Bancorp as of September 30, 2023. On September 16, 2022, the Bank completed its acquisition of Citizens Bank of Cape Vincent (“CBCV”), Cape Vincent, New York, a commercial bank with full-service offices in the villages of Cape Vincent, Chaumont and LaFargeville. At the effective time of the merger, CBCV was merged with and into Gouverneur Savings and Loan Association and each CBCV stockholder became entitled to receive $1,056.11 in cash for each share of CBCV common stock that they held at the effective time of the merger. See Note 3 for more information on the acquisition of CBCV. In conjunction with the acquisition of CBCV, The Bank formed the limited purpose GS&L Municipal Bank in order to continue to hold CBCV’s roughly $24,187,000 in municipal deposits and continue to compete for such deposits in the future. The Municipal Bank is a limited purpose commercial bank that is a wholly owned subsidiary of the Bank and operates under the same regulatory and operating framework as the Bank. The formation of GS&L Municipal Bank included an initial $2.5 million contribution from the Bank. ​ GS&L Municipal Bank is a New York chartered limited purpose commercial bank organized in September 2022 to solicit municipal deposits from local government entities such as towns, cities, school districts, fire districts and other municipalities. The Bank views GS&L Municipal Bank as a source of low cost and stable source of funds that will further the Bank’s commitment to the communities in which the Bank operates. ​ Gouverneur Bancorp, Inc. is a Maryland corporation that was incorporated in June 2023 to be the successor to Gouverneur Bancorp, Inc., a federally chartered corporation (the “Mid-Tier Holding Company”), upon completion of the second-step conversion of Gouverneur Savings and Loan Association (the “Bank”) from the two-tier mutual holding company structure to the stock holding company structure. Cambray Mutual Holding Company was the former mutual holding company for the Mid-Tier Holding Company prior to the completion of the second-step conversion. In conjunction with the second-step conversion, each of Cambray Mutual Holding Company and the Mid-Tier Holding Company merged out of existence and now cease to exist. The second-step conversion was completed on October 31, 2023, at which time the Company sold, for gross proceeds of $7.2 million, a total of 723,068 shares of common stock at $10.00 per share, including 57,845 shares sold to the Bank’s employee stock ownership plan. As part of the second-step conversion, each of the existing outstanding shares of Mid-Tier Holding Company common stock owned by persons other than Cambray Mutual Holding Company was converted into 0.5334 shares of Company common stock. As a result of the second-step conversion, all share information has been subsequently revised to reflect the 0.5334 exchange ratio, unless otherwise noted The Bank provides financial services to individuals and businesses primarily in St. Lawrence, Jefferson and Lewis Counties in New York State. The Bank is subject to regulation by the New York State Department of Financial Services (“NYSDFS”) and Federal Deposit Insurance Corporation (“FDIC”). GS&L Municipal Bank’s principal business focus is to serve the deposit needs of Municipalities that are within the Bank’s three-county market area. Initially, GS&L Municipal Bank will concentrate its business development efforts on St. Lawrence and Jefferson Counties in the state of New York and will focus exclusively on deposit products.

Significant Accounting Policies
Significant Accounting Policies	NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, the Bank, and the Bank’s wholly owned subsidiary, GS&L Municipal Bank. All intercompany accounts and transactions have been eliminated in consolidation. ​ At September 30, 2023 and 2022, GS&L Municipal Bank held $27.5 and $30.4 million, respectively, of the Bank’s $46.6 million investment securities portfolio and $19.7 and $22.8 million, respectively, of the Bank’s deposits. All intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates in Preparation of Financial Statements The preparation of consolidated 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses. In connection with the determination of the estimated loan losses, management obtains independent appraisals for significant properties. The Company’s loans are generally secured by specific items of collateral including real property, consumer assets, and business assets. Although the Company has a diversified portfolio, a substantial portion of its debtors’ ability to honor their contracts is dependent on local economic conditions. While management uses available information to recognize losses on loans and foreclosed assets, further reductions in the carrying amounts of loans and foreclosed assets may be necessary, based on changes in local economic conditions. In addition, regulatory agencies, as an integral part of their examination process, periodically review the estimated losses on loans and foreclosed assets. Such agencies may require the Company to recognize additional losses based on their judgments about information available to them at the time of their examination. Because of these factors, it is reasonably possible that the estimated losses on loans and foreclosed assets may change materially in the near term. However, the amount of the change that is reasonably possible cannot be estimated. Concentrations of Credit Risk At September 30, 2023 and 2022, the Company held approximately $834,000 and $4,235,000, respectively, on deposit with the Federal Reserve Bank and Federal Home Loan Bank of New York which is not insured by the Federal Deposit Insurance Corporation. The Bank operates primarily in St. Lawrence, Jefferson and Lewis Counties, New York and, accordingly, has extended credit primarily to commercial entities and individuals in this area whose ability to honor their contracts is influenced by the region’s economy. These customers are also the primary depositors of the Bank. The Bank is limited in extending credit by legal lending limits to any single borrower or group of borrowers. Note 4 discusses the types of securities the Bank invests in and Note 5 discusses the types of lending in which the Bank engages. Cash and Cash Equivalents For the purpose of reporting on the consolidated statements of cash flows, cash and cash equivalents include cash on hand, amounts due from banks (including cash items in process of clearing) and interest-bearing deposits in banks with an original maturity of 90 days or less. Time Deposits in Other Financial Institutions The majority of the Bank’s time deposits mature within one year and are maintained with major financial institutions in the United States. Interest-bearing, non-transaction account deposits with these financial institutions may exceed the amount of insurance provided on such deposits; however, these deposits typically may be redeemed upon demand and therefore, bear minimal risk. The FDIC insurance coverage is $250,000. The Bank currently has no time deposits that exceed the FDIC insurance coverage. Investment Securities Investment Securities classified as available-for-sale are those that the Company intends to hold for an indefinite period of time but not necessarily to maturity. Any decision to sell a security classified as available-for-sale would be based on various factors, including significant movement in interest rates, changes in the maturity mix of the Company’s assets and liabilities, liquidity needs, regulatory capital considerations and other similar factors. Debt securities available-for-sale are carried at fair value. Unrealized gains and losses are reported in other comprehensive income, net of the related deferred income tax effect. Realized gains or losses, determined on the basis of the cost of the specific securities sold, are included in earnings. Premiums and discounts are recognized in interest income to the call date or to date of maturity. Each method approximates the interest over the terms of the securities. The Company did not hold any equity securities at September 30, 2023 and 2022. Debt securities classified as held-to-maturity are those the Company has both the intent and ability to hold to maturity regardless of changes in market conditions, liquidity needs or changes in general economic conditions. These securities are carried at cost adjusted for the amortization of premium and accretion of discount, computed by the interest method over the terms of the securities. Declines in the fair value of held-to-maturity and available-for-sale securities below their cost, that are deemed to be other than temporary, are reflected in earnings as realized losses. In estimating other than temporary impairment losses, management considers (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, (3) that the Company does not intend to sell these securities, and (4) it is more likely than not that the Company will not be required to sell before a period of time sufficient to allow for any anticipated recovery in fair value. Management determines the appropriate classification of investment securities at the time of purchase and re-evaluates such designation as of each balance sheet date. Investments in Restricted Stock The stock from the Federal Home Loan Bank of New York (“FHLBNY”) and Atlantic Central Bankers Bank (“ACBB”) is restricted as to its marketability. Because no ready market exists for these investments and they have no quoted market value, the Company’s investment in this stock is carried at cost. Each member of the FHLBNY is required to maintain a minimum level of membership stock for as long as it remains a member. The amount of required membership stock is, generally speaking, equal to a specified percentage of “mortgage-related assets” held by the member. Members are also required to purchase activity-based stock in an amount, generally speaking, equal to a specific percentage of the outstanding principal balance of advances extended to the member. Loans Held for Sale ​ Mortgage loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or fair value, as determined by outstanding commitments from investors. Net unrealized losses, if any, are recorded as a valuation allowance and charged to earnings. There were no loans held for sale at September 30, 2023 or 2022. ​ Loans Receivable ​ Loans are carried at the amount of unpaid principal, adjusted for deferred loan fees and origination costs. Interest on loans is accrued based on the principal amounts outstanding. Nonrefundable loan fees and related direct costs are deferred, and the net amount is amortized to income as a yield adjustment over the life of the loan using the interest method. When principal or interest is delinquent for ninety days or more, the Company places the loan on nonaccrual status. ​ After a loan is placed on nonaccrual status, all interest previously accrued but not collected is reversed against current period interest income. Subsequent collections of interest payments on nonaccrual loans are recognized as interest income unless ultimate collectability of the loan is in doubt. Cash collections on loans where ultimate collectability remains in doubt are applied as reductions of the loan principal balance and no interest income is recognized until the principal balance has been collected. ​ Allowance for Loan Losses ​ The allowance for loan losses reflects management’s judgment of probable loan losses inherent in the portfolio at the balance sheet date. The Company uses a disciplined process and methodology to establish the allowance for loan losses each quarter. To determine the total allowance for loan losses, management estimates the reserves needed for each segment of the portfolio, including loans analyzed individually and loans analyzed on a pooled basis. The allowance for loan losses consists of amounts applicable to: (1) the commercial portfolio; (2) the real estate portfolio; and (3) the consumer portfolio. ​ To determine the balance of the allowance account, loans are pooled by portfolio segment and losses are modeled using historical experience and quantitative and other mathematical techniques over the loss emergence period. Management exercises significant judgment in determining the estimation method that fits the credit risk characteristics of each portfolio segment. The Company uses models developed under the guidance of the Office of the Comptroller of the Currency (“OCC”) in this process. Management must use judgment in establishing additional input metrics for the modeling processes. The models and assumptions used to determine the allowance are independently validated and reviewed to ensure that their theoretical foundation, assumptions, data integrity, computational processes, reporting practices, and end-user controls are appropriate and properly documented. ​ The allowance consists of specific and general components. The specific component relates to loans that are classified as doubtful, substandard or special mention. For such loans that are also classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan and collection of the full loan balance is deemed unlikely. The general component covers non-classified loans and is based on historical loss experience adjusted for qualitative factors. ​ The establishment of the allowance for loan losses relies on a consistent process that requires multiple layers of management review and judgment and responds to changes in economic conditions, customer behavior and collateral value, among other influences. From time to time, events or economic factors may affect the loan portfolio, causing management to provide additional amounts to or release balances from the allowance for loan losses. The Company’s allowance for loan losses is sensitive to risk ratings assigned to the individually evaluated loans and economic assumptions and delinquency trends driving statistically modeled reserves. Individual loan risk ratings are evaluated based on each situation by experienced senior credit officers. ​ Management monitors differences between estimated and actual incurred loan losses. This monitoring process includes periodic assessments by senior management of loan portfolios and the models used to estimate incurred losses in those portfolios. Additions to the allowance for loan losses are made by changes to the provision for loan losses. Credit exposures deemed to be uncollectible are charged against the allowance for loan losses. Recoveries of previously charged off amounts are credited to the allowance for loan losses. ​ A loan is considered impaired when, based on current information and events, the Company has concerns about the ability to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. ​ The specific allowance component is used to individually establish an allowance for loans identified for impairment testing. When impairment is identified, a specific reserve may be established based on the Company’s calculation of the estimated loss embedded in the individual loan. Impairment testing includes consideration of the borrower’s overall financial condition, resources and payment record, support available from financial guarantors and the fair market value of the collateral. These factors are combined to estimate the probability and severity of inherent losses. Large groups of smaller balance, homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately evaluate individual consumer and residential loans for impairment. ​ The pooled formula component is used to estimate the losses inherent in the pools of non-classified loans. These loans are then also segregated by loan type and allowance factors are assigned by management based on delinquencies, loss history, trends in volume and terms of loans, effects of changes in lending policy, the experience and depth of management, national and local economic trends, concentrations of credit, results of the loan review system and the effect of external factors (i.e. competition and regulatory requirements). Current economic conditions take into account the average unemployment rate for St. Lawrence, Jefferson and Lewis Counties, New York, the State of New York and for the nation, with the most significance given to the St. Lawrence County data. The allowance factors assigned differ by loan type. ​ Allowance factors and overall size of the allowance may change from period to period based on management’s assessment of the above-described factors and the relative weights given to each factor. In addition, various regulatory agencies periodically review the allowance for loan losses. These agencies may require the Bank to make additions to the allowance for loan losses based on their judgments of collectability based on information available to them at the time of their examination. ​ Loans are placed into a non-accruing status and classified as nonperforming when the principal or interest has been in default for a period of 90 days or more unless the obligation is well secured and in the process of collection. A debt is “well secured” if it is secured by (1) pledges of real or personal property, including securities, that have a realizable value sufficient to discharge the debt (including accrued interest) in full, or (2) the guarantee of a financially responsible party. A debt is “in the process of collection” if collection on the debt is proceeding in due course either through legal action, including judgment enforcement procedure, or, in appropriate circumstances, through collection efforts not involving legal action which are reasonably expected to result in repayment of the debt or in its restoration to a current status. ​ Loans classified as substandard or worse are considered for impairment testing. A substandard loan shows signs of continuing negative financial trends and unprofitability, and therefore is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. The borrower on such loans typically exhibits one or more of the following characteristics: financial ratios and profitability margins are well below industry average; a negative cash flow position exists; debt service capacity is insufficient to the service debt and an improvement in the cash flow position is unlikely within the next twelve months; secondary and tertiary means of debt repayment are weak. Loans classified as substandard are characterized by the probability that the Bank will not collect amounts due according to the contractual terms or will sustain some loss if the deficiencies are not corrected. ​ Loss potential, while existing with respect to the aggregate amount of substandard (or worse) loans, does not have to exist in any individual assets classified as substandard. Such credits are also evaluated for nonaccrual status. ​ Impaired loans include loans that have been classified as substandard or worse. However, certain loans have been paying as agreed and have remained current, with some financial issues related to cash flow that have caused some concern as to the ability of the borrower to perform in accordance with the current loan terms but not to such extent as to require the loan to be put into a non-accruing status. Cash receipts on impaired loans are recorded as interest income as received, unless the loan is in a nonaccrual status. ​ The Company’s charge-off policies by segment of the loan portfolio are as follows: ​ ● Real Estate – The Company generally writes down to the net realizable value based on new appraisal values obtained at the time of possession. ● Consumer Loans – The Company generally fully or partially charges down to the net realizable value at the time of possession. ● Commercial Loans – The Company reviews on a quarterly basis. ​ Premises and Equipment ​ Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. Costs of significant property improvements are capitalized. Maintenance and repairs are expensed as incurred, while major additions and improvements are capitalized. Gains and losses on dispositions are included in current earnings. Depreciation expense is calculated principally on the straight-line method over the following estimated useful lives of the related assets: ​ ​ ​ ​ ​ Years ​ ​ ​ Buildings and Improvements 5 - 39.5 Furniture and Equipment 3 - 7 ​ Foreclosed Assets ​ Foreclosed assets include both formally foreclosed property and in-substance foreclosed property. In-substance foreclosed properties are those properties for which the institution has taken physical possession, regardless of whether formal foreclosure proceedings have taken place. ​ At the time of foreclosure, foreclosed assets are recorded at the fair value less cost to sell, which becomes the property’s new basis. Any write-downs based on the asset’s fair value at date of acquisition are charged to the allowance for loan losses. After foreclosure, management performs periodic valuations and property held for sale is carried at the lower of the new cost basis or fair value less cost to sell. Gains and losses realized on the sale, and any adjustments resulting from periodic re-evaluation of the property are included in noninterest income or expense, as appropriate. Net costs of maintaining and operating the properties are expensed as incurred. Improvements, which extend the life or improve the value of the property, are capitalized as incurred. ​ Transfers of Financial Assets ​ Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free from conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before maturity. ​ Investment in Life Insurance ​ The Company purchased single-premium life insurance on certain employees and executives of the Company and is carried at its cash surrender value. Appreciation in value of the life insurance policies and gain on death proceeds are classified as noninterest income. The cash surrender value received from death proceeds is recorded as a reduction to the carrying value. ​ Income Taxes ​ The Company files a consolidated federal income tax return. Provisions for income taxes are based on taxes payable or refundable for the current year and deferred taxes on temporary differences between the amount of taxable income and pretax financial income. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. ​ Under Financial Accounting Standards Board Accounting Standard Codification (“FASB ASC”), “Accounting for Income Taxes,” the Company recognizes potential liabilities associated with anticipated tax audit issues that may arise during an examination. Interest and penalties that are anticipated to be due upon examination are recognized as accrued interest and other liabilities with an offset to interest and other expense. The Company determined that there were no uncertainties with respect to the application of tax regulations. ​ Advertising Costs ​ The Company follows the policy of charging the costs of advertising to expense as incurred. Advertising expense, included in other non-interest expenses, was approximately $103,000 and $80,000 at September 2023 and 2022, respectively. ​ Fair Value Measurements ​ The Company follows the guidance of FASB ASC 820, Fair Value Measurements and Disclosures. This guidance permits entities to measure many financial instruments and certain other items at fair value. The objective is to improve financial reporting by providing entities with the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. This guidance clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Under this guidance, fair value measurements are not adjusted for transaction costs. The guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). ​ Earnings per Common Share ​ Basic earnings per common share represents income available to common shareholders divided by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflect additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. ​ The following table sets forth the computations of basic and diluted earnings per common share for the years ended September 30 (In Thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ 2023 2022 ​ ​ (In Thousands, except per share data) ​ ​ ​ ​ ​ ​ ​ Net Earnings ​ $ 317 ​ $ 1,527 ​ ​ ​ ​ ​ ​ ​ Basic Earnings Per Common Share, ​ ​ ​ ​ ​ ​ Weighted Average Shares ​ ​ 2,031 ​ ​ 2,031 ​ ​ ​ ​ ​ ​ ​ Diluted Earnings per Common Share, ​ ​ ​ ​ ​ ​ Adjusted Weighted Average Shares ​ ​ 2,031 ​ ​ 2,031 ​ ​ ​ ​ ​ ​ ​ Basic and Diluted Earnings Per Common Share ​ $ 0.16 ​ $ 0.75 ​ There were no dilutive or antidilutive shares at September 30, 2023 or 2022. ​ At September 30, 2023 and 2022, the Company had 352,231 and 352,233 shares of treasury stock, respectively. There were 2 shares of stock retired during the first quarter of fiscal year 2023. ​ Derivative Instruments and Hedging Activities ​ All derivative financial instruments are reported at their fair value either as assets or liabilities. The Company reports net derivatives in a gain position, or derivative assets in the consolidated statements of financial condition as a component of other assets. The Company reports net derivatives in a loss position, or derivative liabilities, in the consolidated statements of financial position as a component of other liabilities. ​ Revenue Recognition ​ The majority of the Company’s revenue stream is generated from interest income on loans and deposits which are outside the scope of “ Revenue from Contracts with Customers”   ​ The Company’s sources of income that fall within the scope of Topic 606 include service charges on deposits, interchange fees and gains and losses on sales of other real estate, all of which are presented as components of noninterest income. Below is a summary of the revenue streams that fall within the scope of Topic 606. ​ Service charges on deposits, ATM, and interchange fees ​ Gains and losses on sales of other real estate – the sale of OREO to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. ​ Valuation of Long-Lived Assets ​ The Company accounts for the valuation of long-lived assets under FASB ASC 360, Property, Plant and Equipment. This guidance requires that long-lived assets and certain identifiable intangible assets be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of the long-lived asset is measured by a comparison of the carrying amount of the asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the estimated fair value of the assets. Assets to be disposed of are reportable at the lower of the carrying amount or fair value, less costs to sell. Comprehensive Loss ​ Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net earnings. Although certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale securities, and the changes in the funded status of pension and post-retirement benefits, are reported as a separate component of the equity section of the consolidated statements of financial condition, such items, along with net earnings, are components of comprehensive loss. ​ Accumulated other comprehensive loss represents the sum of these items, with the exception of net earnings, as of September 30, represented in the table below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended ​ ​ September 30, ​ ​ ​ ​ ​ ​ ​ ​ ​ 2023 ​ 2022 Accumulated Other Comprehensive Loss by Component ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Unrealized Loss for Other Postretirement Obligations ​ $ (326) $ (773) Tax Effect ​ 69 ​ 162 Net Unrealized Loss for Other Postretirement Obligations ​ ​ (257) ​ ​ (611) ​ ​ ​ ​ ​ ​ ​ Unrealized Loss on Available-for-Sale Securities, net ​ ​ (4,890) ​ (4,654) Tax Effect ​ 1,024 ​ 977 Net Unrealized Loss on Available-for-Sale Securities ​ (3,866) ​ (3,677) ​ ​ ​ ​ ​ ​ ​ Total Comprehensive Loss ​ $ (4,123) ​ $ (4,288) ​ Off-Balance Sheet Credit Related Financial Instruments ​ In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under commercial and home equity lines of credit. Such financial instruments are recorded when they are funded. ​ Reclassification ​ Certain accounts in the prior-year consolidated financial statements have been reclassified for comparative purposes to conform with the presentation in the current-year consolidated financial statements. ​ Adoption of Recently Issued Accounting Standards On October 1, 2022, the Company adopted ASU 2021-10 related to guidance on “Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistances”, which aims to provide increased transparency by requiring business entities to disclose information about certain types of government assistance they receive in the notes to the financial statements. Current GAAP has no specific authoritative guidance on the accounting for, or the disclosure of, government assistance received by business entities. The amendments in this Update improve financial reporting by requiring disclosures that increase the transparency of transactions with a government accounted for by applying a grant or contribution accounting model by analogy, including (1) the types of transactions, (2) the accounting for those transactions, and (3) the effect of those transactions on an entity’s financial statements. The Company believes this has no significant impact on the consolidated financial statement and related disclosures. In February 2016, the Financial Accounting Standards Board (the “FASB”) issued ASU 2016-02 to its guidance on “Leases (Topic 842)”. The new leases standard applies a right-of-use (ROU) model that requires a lessee to record, for all leases with a lease term of more than 12 months, an asset representing its right to use the underlying asset and a liability to make lease payments. For leases with a term of 12 months or less, a practical expedient is available whereby a lessee may elect, by class of underlying asset, not to recognize an ROU asset or lease liability. The new leases standard requires a lessor to classify leases as either sales-type, direct financing or operating, similar to existing GAAP. Classification depends on the same five criteria used by lessees plus certain additional factors. The subsequent accounting treatment for all three lease types is substantially equivalent to existing GAAP for sales-type leases, direct financing leases, and operating leases. However, the new standard updates certain aspects of the lessor accounting model to align it with the new lessee accounting model, as well as with the new revenue standard under Topic 606. Lessees and lessors are required to provide certain qualitative and quantitative disclosures to enable users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The adoption of this ASU will result in a gross up of the Consolidated Statements of Condition for right-of-use assets and associated lease liabilities for operating leases in which the Company is the lessee. In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842 - Leases to address certain narrow aspects of the guidance issued in ASU No. 2016-02. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, which amends FASB Accounting Standards Codification (ASC), Leases (Topic 842), to (1) add an optional transition method that would permit entities to apply the new requirements by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the year of adoption, and (2) provide a practical expedient for lessors regarding the separation of the lease and non-lease components of a contract. In December 2018, the FASB issued ASU No. 2018-20, Narrow-Scope Improvements for Lessors, which addresses issues related to (1) sales tax and similar taxes collected from lessees, (2) certain lessor costs, and (3) recognition of variable payments for contracts with lease and non-lease components. In June 2020, the FASB issued No. ASU 2020-05, Coronavirus Disease 2019 (“COVID-19”) in response to the pandemic which has adversely affected the global economy and caused significant and widespread business and capital market disruptions. The FASB is committed to supporting and assisting stakeholders during this difficult time. The FASB issued ASU 2020-05 as a limited deferral of the effective dates o

ACQUISITION OF CITIZENS BANK OF CAPE VINCENT
ACQUISITION OF CITIZENS BANK OF CAPE VINCENT	​ NOTE 3 – ACQUISITION OF CITIZENS BANK OF CAPE VINCENT Effective as of end of business September 16, 2022, Gouverneur completed its acquisition of Citizens Bank of Cape Vincent (“CBCV”). At the effective date of the merger, CBCV was merged with and into Gouverneur Savings and Loan Association and each CBCV stockholder became entitled to receive $1,056.11 in cash for each share of CBCV common stock that they held at the effective date of the acquisition, which resulted in the Company paying $8.4 million in cash for the acquisition. CBCV was a commercial bank with three branches in Jefferson County, New York, located in the villages of Cape Vincent, Chaumont, and LaFargeville, New York. The fair value of the assets acquired as a result of the acquisition totaled $81.9 million; loans totaled $37.0 million and deposits totaled $77.2 million. Goodwill recorded in the acquisition was $4.2 million. The Bank completed the acquisition to further expand the Bank’s footprint and competitive position in Jefferson County and the Lake Ontario, St. Lawrence River communities, offer expanded products and services to the CBCV and Gouverneur customer base, and to enhance its operational opportunities and future earnings. The acquisition of CBCV was accounted for as a business combination using the acquisition method of accounting and, accordingly, assets acquired, liabilities assumed, and consideration paid were recorded at estimated fair values on the acquisition date. In accordance with ASC 805-10-25, the Company utilized the one-year measurement period permitted to adjust the deferred tax balances associated with the September 2022 acquisition of Citizens Bank of Cape Vincent. As a result of this adjustment, the 2023 net deferred tax balance included in other assets was reduced by ($281,000) and goodwill was therefore increased by $281,000. The following table summarizes the consideration paid for CBCV and the fair value of assets acquired and liabilities assumed as of the acquisition date: ​ ​ ​ ​ ​ Purchase Price Consideration ​ ​ ​ ​ ​ ​ ​ Cash Consideration Paid: $ 8,449 ​ ​ ​ ​ Allocation of Purchase Price: ​ ​ ​ Fair Value of Assets Acquired ​ ​ ​ Cash and cash equivalents ​ $ 9,485 Securities available-for-sale ​ ​ 31,166 Loans receivable ​ ​ 37,015 Land, premises and equipment ​ ​ 709 Core deposit intangible ​ ​ 2,542 Other assets ​ ​ 978 ​ ​ ​ ​ Total Assets ​ ​ 81,895 ​ ​ ​ ​ Fair Value of Liabilities Assumed: ​ ​ ​ Deposits ​ $ 77,188 Other liabilities ​ ​ 495 ​ ​ ​ ​ Total Liabilities ​ ​ 77,683 ​ ​ ​ ​ Net Assets Acquired ​ ​ 4,212 ​ ​ ​ ​ Goodwill Recorded in Acquisition ​ $ 4,237 ​ Pursuant to the accounting requirements, the Company assigned a fair value to the assets acquired and liabilities assumed of CBCV. Fair values of the major categories of assets acquired and liabilities assumed were determined as follows: Securities available-for-sale The estimated fair values of the investment securities available for sale, primarily comprised of U.S. Government agency mortgage-backed securities, U.S. government agencies and treasuries, and municipal bonds, were determined using Level 2 inputs in the fair value hierarchy. The fair values were determined using independent pricing services, calculated based on market prices of similar securities, using matrix pricing. Matrix pricing is a mathematical technique commonly used to price debt securities that are not actively traded and values debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities. Loans Receivable Acquired loans (impaired and non-impaired) are initially recorded at their acquisition-date fair values using Level 3 inputs. Fair values are based on a discounted cash flow methodology that involves assumptions and judgments as to credit risk, expected life time losses, environmental factors, collateral values, discount rates, expected payments and expected prepayments. No impaired loans were identified in the analysis so a specific credit fair value adjustment for purchased credit impaired loans subject to ASC 310-30 procedures was not applicable. The acquired loans were recorded at fair value at the acquisition date without carryover of CBCV’s previously established allowance for loan losses. The fair value of the financial assets acquired included loans receivable with a gross amortized cost basis of $38,220,000. The table below illustrates the fair value adjustments made to the amortized cost basis in order to present a fair value of the loans acquired (dollars in thousands). ​ ​ ​ ​ ​ Gross amortized cost basis at September 16, 2022 $ 38,220 Interest rate fair value adjustment on pools of homogeneous loans ​ ​ (834) Credit fair value adjustment on pools of homogeneous loans ​ ​ (371) Credit fair value adjustment on purchased credit impaired loans ​ ​ — ​ ​ ​ ​ Fair value of acquired loans at September 16, 2022 ​ $ 37,015 ​ For loans acquired without evidence of credit quality deterioration, the Bank prepared the interest rate loan fair value and credit fair value adjustments. Loans were grouped into homogeneous pools by characteristics such as loan type, term, collateral and rate. Market rates for similar loans were obtained from various internal and external data sources and reviewed by management for reasonableness. The average of these rates was used as the fair value interest rate a market participant would utilize. A present value approach was utilized to calculate the interest rate fair value discount of $834,000. Additionally for loans acquired without credit deterioration, a credit fair value adjustment was calculated using a two-part credit fair value analysis: 1) an interest rate mark; and 2) credit mark. The interest rate mark was based on an account level discounted cash flow analysis. The credit mark applied to the loans was provided by the Bank’s management for CBCV’s general reserve and specific reserve pool based upon due diligence conducted by the Bank’s management. A credit fair value discount of $371,000 was determined. Both the interest rate and credit fair value adjustments relate to loans acquired with evidence of credit quality deterioration will be substantially recognized as interest income on a level yield amortization method over the expected life of the loans. Land, premises and equipment The Company acquired three branches of CBCV. The fair value of CBCV’s premises, including land, buildings, and improvements, was determined based upon the most recent tax assessment in the market in which the premises are located. Core deposit intangible The fair value of the core deposit intangible was determined using a two-step analytical approach. The first is the estimation of the useful life of the deposits, or attrition rate. All other things being equal, higher attrition rates would translate into a lower deposit intangible. The second step is to determine the net alternative funding cost for the core deposit as well as assumptions regarding costs of servicing core deposit accounts (using a noninterest expense analysis), fee income derived from core deposit accounts, taxes, and a discount rate used to establish a present value for cash flows. Deferred income taxes The transaction is treated for tax purposes as a merger and accordingly, the assets acquired and the liabilities assumed are recorded at “carryover” tax basis equal to CBCV’s tax carrying value immediately preceding the merger. Consequently, deferred tax assets or liabilities are required for each asset or liability for which there is a difference between carryover tax basis and fair value on the transaction date. Deposits Carrying value on the date of acquisition was determined to be fair value. Acquisition-Related Expenses Acquisition-related expenses incurred by the Company associated with the acquisition of CBCV were $558,000 for fiscal year ended September 30, 2022. Such costs include legal and accounting fees, contract termination expenses, system conversion, operations integration, and employee non-compete agreements, which have been expensed as incurred.

The Company had 106 and 143 securities in an unrealized loss position of less than twelve months at September 30, 2023 and September 30, 2022, respectively, which included 74 securities acquired from Citizens Bank of Cape Vincent in September 2022, and 76 and 25 securities in an unrealized loss position of 12 months or more at September 30, 2023 and September 30, 2022, respectively. The Company has the intent and the ability to hold such securities until maturity or market price recovery. Management believes that the unrealized losses do not represent other-than-temporary impairment of the securities.

The Company did acquire a commercial secured performing loan which has been classified as substandard to ensure proper oversight and monitoring of the credit. The credit has performed in accordance with its modified terms for over two years. This loan was restructured in the fiscal 4th quarter of 2023. Proceeds paid off current principal and interest due in the amount of $505,000. Borrower retained the same interest rate of 6.00% and received a 5-year callable note with 25-year amortization in exchange for extra real estate collateral. A $108,000 second position, commercial mortgage was placed on the guarantor’s primary residence behind the Bank’s first position residential mortgage. The restructuring enhances the Bank’s loan-to-value position while providing the borrower with a lower payment than the original contractual terms. The capitalization of interest, interest rate below market terms, and extension of the maturity date were concessions made to the borrower in exchange for additional collateral. The loan remains in non-accrual. Interest income on a restructured loan is accrued once the borrower demonstrates the ability to pay under the restructured terms for sustained period of repayment performance, which is generally six consecutive months. This loan has a fair value adjustment as a result of purchase price accounting of $103,000 at September 30, 2023. The Company sells first mortgage loans to third parties in the course of business, principally to FHLB, a large purchaser of loans. These serviced loans are not included in the balances of the accompanying statements of financial condition, but the Company continues to collect the principal and interest payments for a servicing fee. At September 30, 2023 and September 30, 2022, the total outstanding principal balance on serviced loans was $12.4 million, and $13.3 million, respectively. Citizens Bank of Cape Vincent did not sell residential mortgage loans to third parties. Allowance for Loan Losses The Company has an established methodology to determine the adequacy of the allowance for loan losses that assesses the risks and losses inherent in the Company’s portfolio. For purposes of determining the allowance for loan losses, the Company segments certain loans in its portfolio by product type. The Company’s loans are segmented into the following pools: commercial, real estate and consumer. The Company also sub-segments two of these segments into classes based on the associated risks within those segments. Real estate loans are divided into the following two classes: (a) residential and (b) commercial. Commercial loans are divided into two classes: (a) secured and (b) unsecured. Each class of loan requires significant judgment to determine the estimation method that fits the credit risk characteristics of its portfolio segment. The factors the Company uses to determine the balance of the allowance account for each segment or class of loans are: Consumer Loans Consumer loans are pooled and an historical loss percentage is applied to the pool. Historical loss percentage is calculated using prior eight Based on a credit risk assessment and the Company’s analysis of leading predictors of losses, the Company applies additional loss multipliers to loan balances based on the current economic conditions, delinquency and classification volume, and collateral value and portfolio volume. Real Estate Loans Real estate loans are pooled by portfolio class and an historical loss percentage is applied to each class. Historical loss percentage is calculated using prior eight The Company estimates an additional component of the allowance for loan losses for the non-impaired real estate segment through the application of loss factors to loans grouped by their individual credit risk rating specialists. These ratings reflect the estimated default probability and quality of underlying collateral. Home Equity Lines of Credit (“HELOCs”) approaching their end-of-draw period, when volumes warrant, will be segmented from the mortgage loan pool in the allowance for loan losses estimation process. Management will capture information on a quarterly basis and prepare an analysis to determine the nature and magnitude of the exposure. In addition, based on the Company’s analysis of leading predictors of losses, the Company applies additional loss multipliers to the loan balances. Currently, the Company has applied additional loss estimations based on the current economic conditions, delinquency and classification volume, collateral value, credit concentration, portfolio value and staffing changes. Commercial Secured Loans Commercial secured loans are pooled and an historical loss percentage is applied to the pool. Historical loss percentage is calculated using prior eight Based on a credit risk assessment and the Company’s analysis of leading predictors of losses, the Company applied additional loss multipliers to loan balances based on current delinquency and classification volume, current economic conditions, portfolio volume and staffing changes. Commercial Unsecured Loans Unsecured commercial loans are pooled and an historical loss percentage is applied to the pool. Historical loss percentage is calculated using prior eight Based on credit risk assessment and the Company’s analysis of leading predictors of losses, the Company applied additional loss multipliers to loan balances based on current delinquency and classification volume, current economic conditions, portfolio volume and staffing changes. The Company’s Estimation Process The Company estimates loan losses under multiple economic scenarios to establish a range of potential outcomes for each criterion the Company applies to the allowance calculation. Management applies judgment to develop its own view of loss probability within that range, using external and internal parameters with the objective of establishing an allowance for the losses inherent within these portfolios as of the reporting date. Reflected in the portions of the allowance previously described is the amount which incorporates the range of probable outcomes inherent in estimates used for the allowance, which may change from period to period. This amount is the result of management’s judgment of risks inherent in the portfolios, economic uncertainties, historical loss experience and other factors, including industry trends, calculated to reflect the Company’s view of risk in each loan portfolio. No single statistic or measurement determines the adequacy of the allowance for loan loss. Changes in the allowance for loan losses and the related provision expense can materially affect net earnings. The total allowance reflects management’s estimate of loan losses inherent in the loan portfolio at the balance sheet date. The Company considers the allowance for loan losses of $623,000 adequate to cover loan losses inherent in the loan portfolio at September 30, 2023. The following table presents, by portfolio segment, the changes in the allowance for loan losses and the recorded investment in loans. Allowance for loan losses and recorded investment in loans for the year ended September 30, 2023 was as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Real Estate Real Estate Commercial Commercial ​ ​ ​ ​ Residential ​ Commercial ​ Secured ​ Unsecured ​ Consumer ​ Total ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ Allowance for Credit Losses: ​ ​ ​ ​ ​ ​ Beginning Balance ​ $ 548 ​ $ 55 ​ $ 4 ​ $ 1 ​ $ 13 ​ $ 621 Charge-offs ​ (106) ​ — ​ — ​ (1) ​ (19) ​ (126) Recoveries ​ 1 ​ — ​ — ​ — ​ 5 ​ 6 Transfer ​ (24) ​ — ​ — ​ 2 ​ 22 ​ — Provisions ​ 122 ​ — ​ — ​ — ​ — ​ 122 Ending Balance ​ $ 541 ​ $ 55 ​ $ 4 ​ $ 2 ​ $ 21 ​ $ 623 Ending Balance: Individually ​ ​ ​ ​ ​ ​ Evaluated for Impairment ​ $ — ​ $ — ​ $ — ​ $ — ​ $ — ​ $ — Ending Balance: Collectively ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Evaluated for Impairment ​ $ 541 ​ $ 55 ​ $ 4 ​ $ 2 ​ $ 21 ​ $ 623 Loans Receivable: ​ ​ ​ ​ ​ ​ Ending Balance ​ $ 107,479 ​ $ 11,490 ​ $ 1,501 ​ $ — ​ $ 6,135 ​ $ 126,605 Less: Acquired Loans ​ 27,744 ​ 3,843 ​ 455 ​ — ​ 1,124 ​ 33,166 Ending Balance: Individually ​ ​ ​ ​ ​ ​ Evaluated for Impairment ​ $ — ​ $ 298 ​ $ — ​ $ — ​ $ — ​ $ 298 Ending Balance: Collectively ​ ​ ​ ​ ​ ​ Evaluated for Impairment ​ $ 79,735 ​ $ 7,349 ​ $ 1,046 ​ $ — ​ $ 5,011 ​ $ 93,141 ​ ​ ​ Allowance for loan losses and recorded investment in loans for the year ended September 30, 2022 was as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Real Estate Real Estate Commercial Commercial ​ ​ ​ ​ Residential ​ Commercial ​ Secured ​ Unsecured ​ Consumer ​ Total ​ ​ (In Thousands) Allowance for Credit Losses: ​ ​ ​ ​ ​ ​ Beginning Balance ​ $ 541 ​ $ 64 ​ $ 4 ​ $ 1 ​ $ 10 ​ $ 620 Charge-offs ​ (63) ​ — ​ — ​ — ​ (6) ​ (69) Recoveries ​ 5 ​ — ​ — ​ — ​ 4 ​ 9 Transfer ​ 4 ​ (9) ​ — ​ — ​ 5 ​ — Provisions ​ 61 ​ — ​ — ​ — ​ — ​ 61 Ending Balance ​ $ 548 ​ $ 55 ​ $ 4 ​ $ 1 ​ $ 13 ​ $ 621 Ending Balance: Individually ​ ​ ​ ​ ​ ​ Evaluated for Impairment ​ $ 85 ​ $ — ​ $ — ​ $ — ​ $ — ​ $ 85 Ending Balance: Collectively ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Evaluated for Impairment ​ $ 463 ​ $ 55 ​ $ 4 ​ $ 1 ​ $ 13 ​ $ 536 Loans Receivable: ​ ​ ​ ​ ​ ​ Ending Balance ​ $ 106,584 ​ $ 12,326 ​ $ 2,039 ​ $ 25 ​ $ 5,386 ​ $ 126,360 Less: Acquired Loans ​ 30,193 ​ 4,876 ​ 1,071 ​ — ​ 1,842 ​ 37,982 Ending Balance: Individually ​ ​ ​ ​ ​ ​ Evaluated for Impairment ​ $ 185 ​ $ 278 ​ $ — ​ $ — ​ $ — ​ $ 463 Ending Balance: Collectively ​ ​ ​ ​ ​ ​ Evaluated for Impairment ​ $ 76,206 ​ $ 7,172 ​ $ 968 ​ $ 25 ​ $ 3,544 ​ $ 87,915 ​ The following table presents performing and nonperforming real estate loans based on payment activity for the years ended September 30, 2023 and September 30, 2022, respectively. Real estate loans include residential and commercial mortgages, construction loans and home equity loans. Payment activity is reviewed by management on a quarterly basis to determine how loans are performing. Loans are considered to be nonperforming when the number of days delinquent is greater than 89 days. The loan may only be returned to performing status after considering the borrower’s sustained repayment performance for a reasonable period, generally twelve consecutive months of current payments with no past due occurrences. Nonperforming loans also include certain loans that have been modified in troubled debt restructuring (“TDR”) where economic concessions have been granted to borrowers who have experienced or are expected to experience financial difficulties. These concessions typically result from the Company’s loss mitigation and could include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance or other actions. Certain TDRs are classified as nonperforming at the time of restructure and may only be returned to performing status after considering the borrower’s sustained repayment performance for a reasonable period, generally six consecutive months. Performing and nonperforming real estate loans as of September 30, 2023 and September 30, 2022 were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of September 30, ​ As of September 30, ​ ​ 2023 ​ 2022 ​ ​ (In Thousands) Performing $ 118,269 $ 118,293 Nonperforming ​ 700 ​ 617 Total ​ $ 118,969 ​ $ 118,910 ​ Credit quality indicators as of September 30, 2023 and September 30, 2022 are as follows: Internally assigned grade as a subsection of the “Pass” credit risk profile: 1 — Good Loans to an individual or a well-established business in excellent financial condition with strong liquidity and a history of consistently high levels of earnings and cash flow and debt service capacity. Supported by high quality financial statements (including recent statements and sufficient historical fiscal statements), borrower has excellent repayment history and possesses a documented source of repayment. Industry conditions are favorable and business borrower’s management is well qualified with sufficient debt. Borrower and/or key personnel exhibit unquestionable character. Good loans may be characterized by high quality liquid collateral and very strong personal guarantors. 2 — Satisfactory Loans to borrowers with many of the same qualities as a good loan, however, certain characteristics are not as strong (i.e. cyclical nature of earnings, lower quality financial statements, less liquid collateral, less favorable industry trends, etc.). Borrower still has good credit, will exhibit financial strength, excellent repayment history, and good present and future earnings potential. The primary source of repayment is readily apparent with strong secondary sources of repayment available. Management is capable, with sufficient depth, and character of borrower is well established. 3 — Acceptable Loans to borrowers of average strength with acceptable financial condition (businesses fall within acceptable tolerances of other similar companies represented in the RMA annual statement studies), with satisfactory record of earnings and sufficient historical and projected cash flow to service the debt. Business borrower’s management is capable and reliable. Borrower has satisfactory repayment history, and primary and secondary sources of repayment can be clearly identified. Acceptable loans may exhibit some deficiency or vulnerability to changing economic or industry conditions. 4 — Watch Loans in this category have a chance of resulting in a loss. Characteristics of this level of assets include, but are not limited to; the borrower has only a fair credit rating with minimal recent credit problems, cash flow is currently adequate to meet the required debt repayments, but will not be sufficient in the event of significant adverse developments, borrower has limited access to alternative sources of finance, possibly at unfavorable terms, some management weaknesses exist, collateral, generally required, is sufficient to make likely the recovery of the value of the loan in the event of default, but liquidating the collateral may be difficult or expensive. In addition, the guarantor would achieve this credit rating if it borrowed individually from the Bank. 5 — Special Mention Loans in this category are usually made to well establish businesses with local operations. Special Mention loans have potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or in the institution’s credit position at some future date. Special Mention loans are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification. Special mention category is not to be used as a means of avoiding a clear decision to classify a loan or pass it without criticism. Neither should it include loans listed merely “for the record” when uncertainties and complexities, perhaps coupled with large size, create some reservations about the loan. If weaknesses or evidence of imprudent handling cannot be identified, inclusion of such loans in Special Mention is not justified. Special mention loans have characteristics which corrective management action would remedy. Loans in this category should remain for a relatively short period of time. 6 — Substandard Loans classified as substandard are inadequately protected by the current sound net worth or paying capacity of the borrower or the collateral pledged, if any. Loans in this category have well defined weaknesses that jeopardize the repayment. Loans which might be included in the category have potential for problems due to weakening economic or market conditions. They are characterized by the distinct possibility that the bank will sustain some loss if the deficiencies are not corrected. Substandard loans may include loans which are likely to require liquidation of collateral to effect repayment, and other loans where the character or ability to repay has become suspect. Loss potential, while existing in the aggregate amount of the substandard assets, does not have to exist in individual assets classified substandard. 7 — Doubtful Loans classified as doubtful have all the weaknesses in those classified as substandard with the added characteristics that the weaknesses make collection or liquidation in full on the basis of current existing facts, conditions, and value highly questionable and improbable. Although possibility of loss is extremely high, classification of these loans as loss has been deferred to specific pending factors or events, which may strengthen the loan value (i.e., possibility of additional collateral, injection of capital, collateral liquidation, debt structure, economic recovery, etc.). 8 — Loss Loans classified as loss are considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification does not mean that the asset has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be affected in the future.

Determination of impairment is treated the same across all classes of loans. When the Company identifies a loan as impaired, the Company measures the impairment based on the present value of expected future cash flows, discounted at the loan’s effective interest rate, except when the sole (remaining) source of repayment for the loan is the operation or liquidation of the collateral. In these cases, the Company uses the current fair value of the collateral, less selling costs when foreclosure is probable, instead of discounted cash flows. If the Company determines that the value of the impaired loan is less than the recorded investment in the loan (net of previous charge-offs, deferred loan fees or costs and unamortized premium or discount), the value of impairment will be based on (1) a 90-day default period and (2) all loans classified as TDRs. Also presented is the average recorded investment of the impaired loans and the related amount of interest recognized during the time within the period that the impaired loans were impaired. When the ultimate collectability of the total principal of an impaired loan is in doubt and the loan is on nonaccrual status, all payments are applied to principal under the cost recovery method. When the ultimate collectability of the total principal of an impaired loan is not in doubt and the loan is on nonaccrual status, contractual interest is credited to interest income when received, under the cash basis method. The average balances are calculated based on the month-end balances of the financing receivables of the period reported. The Company determines the specific allowance for impaired financing receivables based on the present value of expected future cash flows, discounted at the loan’s effective interest rate, except when the remaining source of repayment for the loan was the operation or liquidation of the collateral. In those cases, the current fair value of the collateral less selling costs was used to determine the specific allowance recorded. There were no recorded investment balances for impaired financing receivables at September 30, 2023 or September 30, 2022. There were no loans recorded for impaired financing receivables with an associated specific allowance reserve at September 30, 2023. There were two loans with principal balances totaling $185,000 recorded for impaired financing receivables with an associated specific allowance reserve at September 30, 2022. Non-Accrual Loans The Company generally places loans on nonaccrual status when the loans reach 90 days past due or the full and timely collection of interest or principal balance has been charged off and no restructuring has occurred. When the Company places a loan on nonaccrual status, the Company reverses the accrued unpaid interest receivable against interest income and accounts for the loan on the cash or cost recovery method until it qualifies for return to accrual status. Generally, the Company returns a loan to accrual status when (1) all delinquent interest and principal become current under the terms of the loan agreement and the Company expects repayment of the remaining contractual obligation or (2) the loan is well-secured, the borrower has made three consecutive payments, and collectability is no longer doubtful. The Company has determined that the entire balance of a loan is contractually delinquent for all classes if the minimum payment is not received by the specified due date on the customer’s statement. Interest and fees continue to accrue on past due loans until the date the loan goes into nonaccrual status, if applicable. Non-Performing Assets The table below sets forth information regarding our non-performing assets. Non-accrual loans include non-accruing troubled debt restructurings of $538,000 and $20,000, respectively, as of September 30, 2023 and 2022. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, ​ ​ ​ 2023 ​ 2022 ​ ​ ​ (Dollars in thousands) ​ ​ ​ ​ ​ Non-accrual loans: ​ ​ Real estate loans: ​ ​ One- to four-family residential $ 186 ​ $ 607 Commercial 402 ​ 296 Construction — ​ — Home equity loans and lines of credit — ​ — Commercial loans — ​ — Consumer loans: ​ Automobile — ​ — Passbook — ​ — Other consumer 9 ​ 10 Total non-accrual loans $ 597 ​ $ 913 ​ Troubled Debt Restructurings (“TDR”) In situations where, for economic or legal reasons related to a customer’s financial difficulties, the Company grants a concession for other than an insignificant period of time to the customer that the Company would not otherwise consider, the related loan is classified as a TDR. The Company strives to identify customers in financial difficulty early and work with them to modify to more affordable terms before their loan reaches nonaccrual status. These modified terms may include rate reductions, principal forgiveness, payment forbearance and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of the collateral. In cases where the Company grants the customer new terms and provides for a reduction of either interest or principal, the Company measures any impairment on the restructuring as previously noted for impaired loans. Loans identified as impaired through a TDR are classified in the Allowance for Loan Losses using similar criteria as, and pooled with, specific impaired loans. There were two new loans modified as TDR during the fiscal year ended September 30, 2023, and no new loans classified as TDR for the year ended September 30, 2022. The Company acquired a commercial secured performing loan which has been classified as substandard to ensure proper oversight and monitoring of the credit. The credit has performed in accordance with its modified terms for over two years. This loan was restructured in the fiscal 4th quarter of 2023. Proceeds paid off current principal and interest due in the amount of $505,000. The borrower retained the same interest rate of 6.00% and received a 5-year callable note with 25-year amortization in exchange for extra real estate collateral. A $108,000 second position, commercial mortgage was placed on the guarantor’s primary residence behind the Bank’s first position residential mortgage. The other loan modified as a TDR during fiscal year 2023 was a one-to-four-family adjustable-rate residential loan with a pre-modified balance of $11,000 and a 7.25% interest rate. Proceeds paid off current principal, taxes and closing costs when this loan modified into a fixed-rate one-to-four-family residential loan with a balance of $16,000 and a 6.50% interest rate. The maturity date of September 2023 was extended to October 2028 under the new terms. There were no TDR’s in payment default that were previously classified as a TDR in the previous twelve months.

The provision for federal income taxes, which differs from that computed by applying federal statutory rates to income before federal income tax expense, is summarized as follows for the years ended September 30: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2023 2022 ​ ​ ​ ​ % of Pretax ​ ​ ​ % of Pretax ​ ​ Amount ​ Income ​ Amount ​ Income ​ ​ (In Thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Federal Tax at Statutory Rates ​ $ 49 21.0 % $ 403 21.0 % Earnings on Investment in Life Insurance ​ (29) (12.4) % (29) (1.5) % Tax-Exempt Interest Income ​ (131) (56.2) % (117) (6.1) % Acquisition-Related Expenses ​ — — % 113 5.9 % Other ​ 27 11.6 % 22 1.1 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total Federal Tax ​ $ (84) (36.0) % $ 392 20.4 % ​ The net deferred tax asset included in accrued interest receivable and other assets in the accompanying consolidated statements of financial condition includes the following amounts of deferred tax assets and liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ 2023 2022 ​ ​ (In Thousands) Deferred Tax Assets: ​ ​ Net Operating Loss Carryforward ​ $ 821 ​ $ 804 Allowance for Loan Losses ​ 131 ​ 130 Retirement Benefits ​ 373 ​ 423 Deferred Compensation ​ 134 ​ 153 Net Unrealized Loss on Securities ​ 1,566 ​ 1,601 Fair Value Marks on Acquired Loans ​ 208 ​ 253 Other ​ 24 ​ 26 Total Deferred Tax Assets ​ 3,257 ​ 3,390 ​ ​ ​ ​ ​ ​ ​ Deferred Tax Liabilities ​ ​ Interest Rate Swap Derivative Liability ​ 52 ​ 221 Premises and Equipment ​ 144 ​ 54 Net Deferred Loan Costs ​ 92 ​ 121 Core Deposit Intangible ​ 437 ​ 534 Total Deferred Tax Liabilities ​ 725 ​ 930 ​ ​ ​ ​ ​ ​ ​ Net Deferred Tax Asset ​ $ 2,532 ​ $ 2,460 ​ At September 30, 2023, the Company had $3,910,000 of federal net operating losses, which can be carried forward indefinitely. Utilization of $1,259,000 of these net operating losses is subject to an annual limitation under tax rules applicable to ownership changes. Realization of deferred tax assets is dependent upon the generation of future taxable income. A valuation allowance is provided when it is more likely than not that at least some portion of the deferred tax assets will not be realized. In assessing the need for a valuation allowance, management considers the scheduled reversal of the deferred tax liabilities, the level of historical taxable income and the projected future level of taxable income over the periods in which the temporary differences comprising the deferred tax assets will be deductible. The judgement about the level of future taxable income is inherently subjective and is reviewed on a continual basis and as regulatory and business factors change. At September 30, 2023 and 2022, management determined that a valuation allowance was not deemed necessary. At September 30, 2023 and 2022, the Company had an unrecaptured pre-1988 federal bad debt reserve of approximately $1.3 million for which no federal income tax provision has been made. A deferred tax liability has not been provided on this amount, as management does not intend to redeem stock, make distributions or take other actions that would result in recapture of the reserve. The Company files consolidated federal and combined New York State income tax returns. Based on provisions in New York State tax law, the Company does not generate New York taxable income, resulting in a tax liability that is based on taxable capital. Accordingly, this tax liability is recorded in other non-interest expenses.

TRANSACTIONS WITH EXECUTIVE OFFICERS AND DIRECTORS	NOTE 14 – TRANSACTIONS WITH EXECUTIVE OFFICERS AND DIRECTORS Certain directors and executive officers of the Company, their families and their affiliates are customers of the Bank. Any transactions with such parties, including loans and commitments, were in the ordinary course of business at normal terms, including interest rates and collateralization prevailing at the time, and did not represent more than normal risks. At September 30, 2023 and 2022, such loans amounted to approximately $623,000 and $570,000, respectively. During 2023 and 2022, new originated loans to such related parties and loans associated with newly appointed directors and officers totaled $130,000 and $327,000, respectively, and repayments aggregated approximately $78,000 and $24,000, respectively.

FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET CREDIT RISK
FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET CREDIT RISK	NOTE 15 — FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET CREDIT RISK The Bank is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and to sell loans. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated statements of financial condition. The Bank’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual amount of those instruments. The Bank uses the same credit policies in making commitments and conditional obligations as it does for on- balance sheet instruments. A summary of financial instrument commitments at September 30, 2023 and 2022 is shown below. ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, September 30, ​ 2023 2022 ​ ​ (in thousands) Commitments to Grant Loans ​ $ 1,089 ​ $ 1,759 Unfunded Commitments Under Lines of Credit ​ $ 6,022 ​ $ 6,455 ​ Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since some of the commitments are expected to expire without being drawn upon, the total commitment amount does not necessarily represent future cash requirements. The Bank evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Bank upon extension of credit, is based on management’s credit evaluation of the customer and generally consists of real estate.

REGULATORY CAPITAL REQUIREMENTS.
REGULATORY CAPITAL REQUIREMENTS	NOTE 16 — REGULATORY CAPITAL REQUIREMENTS The Bank is subject to regulatory capital requirements administered by banking regulators. Failure to meet minimum capital requirements can trigger certain mandatory — and possibly additional discretionary — actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank’s assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. U.S. Basel III Capital Rules In July 2013, the Federal Reserve Board approved final rules (the “U.S. Basel III Capital Rules”) establishing a new comprehensive capital framework for U.S. banking organizations and implementing the Basel Committee on Banking Supervision’s December 2010 framework for strengthening international capital standards. The U.S. Basel III Capital Rules substantially revised the risk-based capital requirements applicable to bank holding companies and depository institutions. The minimum regulatory capital requirements established by the U.S. Basel III Capital Rules became effective for the Bank on January 1, 2016 and become fully phased in on January 1, 2019. The U.S. Basel III Capital Rules require the Bank to: ● Meet a minimum Common Equity Tier 1 Capital ratio of 4.50% of risk-weighted assets and a minimum Tier 1 Capital of 6.00% of risk-weighted assets; ● Continue to require a minimum Total Capital ratio of 8.00% of risk-weighted assets and a minimum Tier 1 Leverage Capital ratio of 4.00% of average assets; ● Maintain a “capital conservation buffer” of 2.50% above the minimum risk-based capital requirements, which must be maintained to avoid restrictions on capital distributions and certain discretionary bonus payments; and ● Comply with a revised definition of capital to improve the ability of regulatory capital instruments to absorb losses. Certain non-qualifying capital instruments, including cumulative preferred stock and TruPS, will be excluded as a component of Tier 1 capital for institutions of the Company’s size. The U.S. Basel III Capital Rules use a standardized approach for risk weightings that expand the risk- weightings for assets and off-balance sheet exposures from the previous 0%, 20%, 50% and 100% categories to a much larger and more risk-sensitive number of categories, depending on the nature of the assets and off- balance sheet exposures, resulting in higher risk weights for a variety of asset categories. The capital conservation buffer at September 30, 2023 and September 30, 2022 is 2.50%. The Bank exceeded these “well-capitalized” and “capital conservation buffer” ratios for all periods presented. As of September 30, 2023 and September 30, 2022, the Bank’s capital levels meet the fully phased-in minimum capital requirements, including the new capital conservation buffers, as prescribed in the U.S. Basel III Capital Rules. As of September 30, 2023 and September 30, 2022, the most recent notification from Federal Deposit Insurance Corporation (“FDIC”) categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since the most recent notification that management believes have changed the Bank’s prompt corrective action category. There are no comparable minimum capital requirements that apply to the Company as a savings and loan holding company. The Bank’s actual and required capital amounts and ratios are presented in the table below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Minimum to be Well ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Capitalized Under Prompt ​ ​ ​ ​ ​ ​ ​ Minimum Capital ​ Corrective Action ​ Actual Requirement Provisions ​ Amount ($) Ratio (%) Amount ($) Ratio (%) Amount ($) Ratio (%) ​ ​ (In Thousands) As of September 30, 2023 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total Capital (to Risk-Weighted Assets) ​ $ 21,906 19.4 ≥ $ 9,020 ≥ 8.0 ≥ $ 11,275 ≥ 10.0 Tier 1 Capital (to Risk-Weighted Assets) ​ 21,283 18.9 ≥ 6,765 ≥ 6.0 ≥ 9,019 ≥ 8.0 Tier 1 Common Equity (to Risk-Weighted Assets) ​ 21,283 18.9 ≥ 5,074 ≥ 4.5 ≥ 7,329 ≥ 6.5 Tier 1 Leverage Ratio (to Adjusted Total Assets) ​ 21,283 10.6 ≥ 8,022 ≥ 4.0 ≥ 10,027 ≥ 5.0 Capital Conservation Buffer on Tier 1 Common Equity ​ 21,906 11.4 ≥ 7,892 ≥ 7.0 ≥ N/A ≥ N/A ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of September 30, 2022 ​ Total Capital (to Risk-Weighted Assets) ​ $ 22,662 19.9 ≥ $ 9,110 ≥ 8.0 ≥ $ 11,387 ≥ 10.0 Tier 1 Capital (to Risk-Weighted Assets) ​ 22,041 19.4 ≥ 6,832 ≥ 6.0 ≥ 9,110 ≥ 8.0 Tier 1 Common Equity (to Risk-Weighted Assets) ​ 22,041 19.4 ≥ 5,124 ≥ 4.5 ≥ 7,402 ≥ 6.5 Tier 1 Leverage Ratio (to Adjusted Total Assets) ​ 22,041 15.8 ≥ 5,582 ≥ 4.0 ≥ 6,978 ≥ 5.0 Capital Conservation Buffer on Tier 1 Common Equity ​ 22,662 11.9 ≥ 7,971 ≥ 7.0 ≥ N/A ≥ N/A ​ GS&L Municipal Bank’s actual and required capital amounts and ratios are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Minimum to be Well ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Capitalized Under Prompt ​ ​ ​ ​ ​ ​ ​ Minimum Capital ​ Corrective Action ​ ​ Actual ​ Requirement ​ Provisions ​ Amount ($) Ratio (%) ​ Amount ($) ​ Ratio (%) ​ Amount ($) ​ Ratio (%) ​ ​ (In Thousands) As of September 30, 2023 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total Capital (to Risk-Weighted Assets) ​ $ 13,053 245.8 ≥ $ 425 ≥ 8.0 ≥ $ 531 ≥ 10.0 Tier 1 Capital (to Risk-Weighted Assets) ​ ​ 13,053 245.8 ≥ ​ 319 ≥ 6.0 ≥ ​ 425 ≥ 8.0 Tier 1 Common Equity (to Risk-Weighted Assets) ​ ​ 13,053 245.8 ≥ ​ 239 ≥ 4.5 ≥ ​ 345 ≥ 6.5 Tier 1 Leverage Ratio (to Adjusted Total Assets) ​ ​ 13,053 37.4 ≥ ​ 1,394 ≥ 4.0 ≥ ​ 1,743 ≥ 5.0 Capital Conservation Buffer on Tier 1 Common Equity ​ ​ 13,053 237.8 ≥ ​ 372 ≥ 7.0 ≥ ​ N/A ≥ N/A ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of September 30, 2022 ​ ​ Total Capital (to Risk-Weighted Assets) ​ $ 12,160 136.1 ≥ $ 715 ≥ 8.0 ≥ $ 894 ≥ 10.0 Tier 1 Capital (to Risk-Weighted Assets) ​ ​ 12,160 136.1 ≥ ​ 536 ≥ 6.0 ≥ ​ 715 ≥ 8.0 Tier 1 Common Equity (to Risk-Weighted Assets) ​ ​ 12,160 136.1 ≥ ​ 402 ≥ 4.5 ≥ ​ 581 ≥ 6.5 Tier 1 Leverage Ratio (to Adjusted Total Assets) ​ ​ 12,160 35.7 ≥ ​ 1,364 ≥ 4.0 ≥ ​ 1,705 ≥ 5.0 Capital Conservation Buffer on Tier 1 Common Equity ​ ​ 12,160 128.1 ≥ ​ 625 ≥ 7.0 ≥ ​ N/A ≥ N/A ​

INTEREST RATE DERIVATIVES
INTEREST RATE DERIVATIVES	NOTE 18 — INTEREST RATE DERIVATIVES Derivative instruments are entered into primarily as a risk management tool of the Company. It has entered into several interest rate swap agreements whereby it pays a fixed rate and receives a variable rate on a notional amount. It did so to hedge the cost of certain borrowings and to increase the interest rate sensitivity of certain assets. Financial derivatives are recorded at fair value as other assets or liabilities. The accounting for changes in the fair value of a derivative depends on whether it has been designated and qualifies as a part of a hedging relationship. For a fair value hedge, changes in the fair value of the derivative instrument and changes in the fair value of the hedged asset or liability are currently recognized in current year earnings. Amounts recognized in earnings as noninterest gain (loss) for the years ended September 30, 2023 and 2022 were $(802,000) and $2,158,000, respectively. The gain/loss is the result of the swaps market value fluctuations with long-term bond rates and projected short-term rates. See Note 19 for further discussion on the fair value of the interest rate derivative. On December 9, 2022, the Company unwound two off-balance sheet swaps, $6.0 million in notional value, for a realized gain of approximately $343,000. On December 14, 2022, the Company sold four investments totaling $2.0 million for a total loss of approximately $342,000, which closely matches the realized gain on the unwound swaps. $2.0 million was reinvested into two new securities. On February 14, 2023, the Company unwound two off-balance sheet swaps, $5.0 million in notional value, for a realized gain of approximately $310,000. On February 14, 2023, the Company sold ten underperforming investments totaling $3.65 million for a total loss of approximately $318,000, which closely matched the realized gain on the unwound swaps. $3.09 million was reinvested into three new securities.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS
FAIR VALUE MEASUREMENTS	NOTE 19 — FAIR VALUE MEASUREMENTS Determination of Fair Value The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. In accordance with the Fair Value Measurements and Disclosures Recent fair value guidance provides a consistent definition of fair value, which focuses on exit price in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value, a reasonable point within the range, is most representative of fair value under current market conditions. Fair Value Hierarchy In accordance with this guidance, the Company groups its financial assets and financial liabilities generally measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. ● Level 1 — Valuation is based on quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Level 1 assets and liabilities generally include debt and equity securities that are traded in an active exchange market. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. ● Level 2 — Valuation is based on inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly or indirectly. The valuation may be based on quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability. ● Level 3 — Valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which determination of fair value requires significant management judgment or estimation. The types of instruments valued based on quoted market prices in active markets include most U.S. government and agency securities, liquid mortgage products, active listed equities and most money market securities. Such instruments are generally classified within Level 1 or Level 2 of the fair value hierarchy. As required by this guidance, the Company does not adjust the quoted price for such instruments. The types of instruments valued based on quoted prices in markets that are not active, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency include most investment- grade and high-yield corporate bonds, less liquid mortgage products, less liquid equities, state, municipal and provincial obligations, and certain physical commodities. Such instruments are generally classified within Level 2 of the fair value hierarchy. The Company utilizes interest rate swap agreements based on the Secured Overnight Financing Rate (SOFR). The Company generally determines the fair value of its interest rate swap agreements using externally developed pricing models based on market observable inputs and therefore classifies such valuations as Level 2. Level 3 is for positions that are not traded in active markets or are subject to transfer restrictions. Valuations are adjusted to reflect illiquidity and/or non-transferability, and such adjustments are generally based on available market evidence. In the absence of such evidence, management’s best estimate is used. Impaired loans are evaluated and valued at the time the loan is identified as impaired, at the lower of cost or market value. Market value is measured based on the value of the collateral securing these loans and is classified at a level 3 in the fair value hierarchy. Collateral may be real estate and/or business assets including equipment, inventory and/or accounts receivable. The value of business equipment, inventory and accounts receivable collateral is based on the net book value on the business’ financial statements and, if necessary, discounted based on management’s review and analysis. Appraised and reported values may be discounted based on management’s historical knowledge, changes in market conditions from the time of valuation and/or management’s expertise and knowledge of the client’s business. Impaired loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly, based on the same factors identified previously. Foreclosed properties are adjusted to fair value upon transfer of the loans to foreclosed properties. Subsequently, foreclosed properties are carried at the lower of carrying value or fair value. The estimated fair value for foreclosed properties included in Level 3 is determined by independent market-based appraisals and other available market information, less costs to sell, that may be reduced further based on market expectations or an executed sales agreement. If fair value of the collateral deteriorates subsequent to initial recognition, the Company records the foreclosed properties as a nonrecurring Level 3 adjustment. Valuation techniques are consistent with those techniques applied in prior periods. The following table present the assets required to be measured and reported on a recurring basis on the Company’s Consolidated Statements of Financial Condition at their fair value as of September 30, 2023 and September 30, 2022 by level within the fair value hierarchy. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Quoted Prices in ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Active Markets ​ ​ ​ ​ ​ ​ ​ ​ for Identical Significant Other Significant ​ ​ Total Assets/Liabilities ​ Observable ​ Unobservable ​ Fair Value (Level 1 ) Inputs (Level 2) Inputs (Level 3) ​ (In Thousands) September 30, 2023 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. Government Treasuries ​ $ 3,680 ​ $ — ​ $ 3,680 ​ $ — U.S. Government Agencies ​ ​ 11,662 ​ ​ — ​ ​ 11,662 ​ ​ — Mortgaged-Backed Securities ​ ​ 7,915 ​ ​ — ​ ​ 7,915 ​ ​ — Municipal Securities ​ ​ 20,995 ​ ​ — ​ ​ 20,995 ​ ​ — SBA Securities ​ ​ 2,372 ​ ​ — ​ ​ 2,372 ​ ​ — Available-for-Sale Securities ​ $ 46,624 ​ $ — ​ $ 46,624 ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Interest Rate Swap Derivative ​ $ 250 ​ $ — ​ $ 250 ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2022 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. Government Treasuries ​ $ 4,159 ​ $ — ​ $ 4,159 ​ $ — U.S. Government Agencies ​ ​ 10,323 ​ ​ — ​ ​ 10,323 ​ ​ — Mortgaged-Backed Securities ​ ​ 8,440 ​ ​ — ​ ​ 8,440 ​ ​ — Municipal Securities ​ ​ 24,944 ​ ​ — ​ ​ 24,944 ​ ​ — SBA Securities ​ ​ 1,779 ​ ​ — ​ ​ 1,779 ​ ​ — Available-for-Sale Securities ​ $ 49,645 ​ $ — ​ $ 49,645 ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Interest Rate Swap Derivative ​ $ 1,051 ​ $ — ​ $ 1,051 ​ $ — ​ Certain assets and liabilities may be required to be measured at fair value on a nonrecurring basis in periods subsequent to their initial recognition.

LEASES
LEASES	NOTE 20 — LEASES A lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. On October 1, 2022, the Company adopted ASU No 2016-02 “ Leases” (Topic 842) The leases in which the Company is the lessee include real estate property for a branch office facility under a noncancelable operating lease arrangement, whose current maturity date is November 2026 at which point, it automatically renews for a three-year term at the end of each renewal. The Bank also leases various equipment which expire at various dates through March 2026. All of the Company’s leases are classified as operating leases. Topic 842 requires the Company to recognize a right-of-use (“ROU”) asset and corresponding lease liability included in other assets and other liabilities, respectively, on the Company’s consolidated statements of financial condition. There were no net lease costs during the year ended September 30, 2022. The Company’s real estate lease agreements include an option to renew at the Company’s discretion. Future maturities of operating lease liabilities with initial or remaining terms of one year or more as of September 30, 2023 are as follows: ​ ​ ​ ​ ​ 2024 ​ $ 24,000 2025 ​ 21,000 2026 ​ 14,000 2027 ​ 13,000 2028 ​ 13,000 ​ ​ $ 85,000 ​ Lease expense for the branch office amounted to $13,000 for the year ended September 30, 2023. Lease expense for the equipment was approximately $11,000 for the year ended September 30, 2023. The following tables present information about the Company’s leases and of and for the year ended September 30, 2023: ​ ​ ​ ​ ​ Right to use assets $ 19,000 Lease liability ​ $ 19,000 Weighted average remaining lease term, in years: ​ ​ 2.52 For the year ended September 30, 2023: ​ ​ ​ Operating lease expense: ​ $ 23,000 Short-term lease expense: ​ 1,000 Total lease expense: ​ $ 24,000 Cash paid for amounts included in measurement of lease liabilities: ​ $ 24,000 ​

Significant Accounting Policies
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, the Bank, and the Bank’s wholly owned subsidiary, GS&L Municipal Bank. All intercompany accounts and transactions have been eliminated in consolidation. ​ At September 30, 2023 and 2022, GS&L Municipal Bank held $27.5 and $30.4 million, respectively, of the Bank’s $46.6 million investment securities portfolio and $19.7 and $22.8 million, respectively, of the Bank’s deposits. All intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates in Preparation of Financial Statements	Use of Estimates in Preparation of Financial Statements The preparation of consolidated 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses. In connection with the determination of the estimated loan losses, management obtains independent appraisals for significant properties. The Company’s loans are generally secured by specific items of collateral including real property, consumer assets, and business assets. Although the Company has a diversified portfolio, a substantial portion of its debtors’ ability to honor their contracts is dependent on local economic conditions. While management uses available information to recognize losses on loans and foreclosed assets, further reductions in the carrying amounts of loans and foreclosed assets may be necessary, based on changes in local economic conditions. In addition, regulatory agencies, as an integral part of their examination process, periodically review the estimated losses on loans and foreclosed assets. Such agencies may require the Company to recognize additional losses based on their judgments about information available to them at the time of their examination. Because of these factors, it is reasonably possible that the estimated losses on loans and foreclosed assets may change materially in the near term. However, the amount of the change that is reasonably possible cannot be estimated.
Concentrations of Credit Risk	Concentrations of Credit Risk At September 30, 2023 and 2022, the Company held approximately $834,000 and $4,235,000, respectively, on deposit with the Federal Reserve Bank and Federal Home Loan Bank of New York which is not insured by the Federal Deposit Insurance Corporation. The Bank operates primarily in St. Lawrence, Jefferson and Lewis Counties, New York and, accordingly, has extended credit primarily to commercial entities and individuals in this area whose ability to honor their contracts is influenced by the region’s economy. These customers are also the primary depositors of the Bank. The Bank is limited in extending credit by legal lending limits to any single borrower or group of borrowers. Note 4 discusses the types of securities the Bank invests in and Note 5 discusses the types of lending in which the Bank engages.
Cash and Cash Equivalents	Cash and Cash Equivalents For the purpose of reporting on the consolidated statements of cash flows, cash and cash equivalents include cash on hand, amounts due from banks (including cash items in process of clearing) and interest-bearing deposits in banks with an original maturity of 90 days or less.
Time Deposits in Other Financial Institutions	Time Deposits in Other Financial Institutions The majority of the Bank’s time deposits mature within one year and are maintained with major financial institutions in the United States. Interest-bearing, non-transaction account deposits with these financial institutions may exceed the amount of insurance provided on such deposits; however, these deposits typically may be redeemed upon demand and therefore, bear minimal risk. The FDIC insurance coverage is $250,000. The Bank currently has no time deposits that exceed the FDIC insurance coverage.
Investment Securities	Investment Securities Investment Securities classified as available-for-sale are those that the Company intends to hold for an indefinite period of time but not necessarily to maturity. Any decision to sell a security classified as available-for-sale would be based on various factors, including significant movement in interest rates, changes in the maturity mix of the Company’s assets and liabilities, liquidity needs, regulatory capital considerations and other similar factors. Debt securities available-for-sale are carried at fair value. Unrealized gains and losses are reported in other comprehensive income, net of the related deferred income tax effect. Realized gains or losses, determined on the basis of the cost of the specific securities sold, are included in earnings. Premiums and discounts are recognized in interest income to the call date or to date of maturity. Each method approximates the interest over the terms of the securities. The Company did not hold any equity securities at September 30, 2023 and 2022. Debt securities classified as held-to-maturity are those the Company has both the intent and ability to hold to maturity regardless of changes in market conditions, liquidity needs or changes in general economic conditions. These securities are carried at cost adjusted for the amortization of premium and accretion of discount, computed by the interest method over the terms of the securities. Declines in the fair value of held-to-maturity and available-for-sale securities below their cost, that are deemed to be other than temporary, are reflected in earnings as realized losses. In estimating other than temporary impairment losses, management considers (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, (3) that the Company does not intend to sell these securities, and (4) it is more likely than not that the Company will not be required to sell before a period of time sufficient to allow for any anticipated recovery in fair value. Management determines the appropriate classification of investment securities at the time of purchase and re-evaluates such designation as of each balance sheet date. Investments in Restricted Stock The stock from the Federal Home Loan Bank of New York (“FHLBNY”) and Atlantic Central Bankers Bank (“ACBB”) is restricted as to its marketability. Because no ready market exists for these investments and they have no quoted market value, the Company’s investment in this stock is carried at cost. Each member of the FHLBNY is required to maintain a minimum level of membership stock for as long as it remains a member. The amount of required membership stock is, generally speaking, equal to a specified percentage of “mortgage-related assets” held by the member. Members are also required to purchase activity-based stock in an amount, generally speaking, equal to a specific percentage of the outstanding principal balance of advances extended to the member.
Loans Held for Sale	Loans Held for Sale ​ Mortgage loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or fair value, as determined by outstanding commitments from investors. Net unrealized losses, if any, are recorded as a valuation allowance and charged to earnings. There were no loans held for sale at September 30, 2023 or 2022.
Loans Receivable	Loans Receivable ​ Loans are carried at the amount of unpaid principal, adjusted for deferred loan fees and origination costs. Interest on loans is accrued based on the principal amounts outstanding. Nonrefundable loan fees and related direct costs are deferred, and the net amount is amortized to income as a yield adjustment over the life of the loan using the interest method. When principal or interest is delinquent for ninety days or more, the Company places the loan on nonaccrual status. ​ After a loan is placed on nonaccrual status, all interest previously accrued but not collected is reversed against current period interest income. Subsequent collections of interest payments on nonaccrual loans are recognized as interest income unless ultimate collectability of the loan is in doubt. Cash collections on loans where ultimate collectability remains in doubt are applied as reductions of the loan principal balance and no interest income is recognized until the principal balance has been collected.
Allowance for Loan Losses	Allowance for Loan Losses ​ The allowance for loan losses reflects management’s judgment of probable loan losses inherent in the portfolio at the balance sheet date. The Company uses a disciplined process and methodology to establish the allowance for loan losses each quarter. To determine the total allowance for loan losses, management estimates the reserves needed for each segment of the portfolio, including loans analyzed individually and loans analyzed on a pooled basis. The allowance for loan losses consists of amounts applicable to: (1) the commercial portfolio; (2) the real estate portfolio; and (3) the consumer portfolio. ​ To determine the balance of the allowance account, loans are pooled by portfolio segment and losses are modeled using historical experience and quantitative and other mathematical techniques over the loss emergence period. Management exercises significant judgment in determining the estimation method that fits the credit risk characteristics of each portfolio segment. The Company uses models developed under the guidance of the Office of the Comptroller of the Currency (“OCC”) in this process. Management must use judgment in establishing additional input metrics for the modeling processes. The models and assumptions used to determine the allowance are independently validated and reviewed to ensure that their theoretical foundation, assumptions, data integrity, computational processes, reporting practices, and end-user controls are appropriate and properly documented. ​ The allowance consists of specific and general components. The specific component relates to loans that are classified as doubtful, substandard or special mention. For such loans that are also classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan and collection of the full loan balance is deemed unlikely. The general component covers non-classified loans and is based on historical loss experience adjusted for qualitative factors. ​ The establishment of the allowance for loan losses relies on a consistent process that requires multiple layers of management review and judgment and responds to changes in economic conditions, customer behavior and collateral value, among other influences. From time to time, events or economic factors may affect the loan portfolio, causing management to provide additional amounts to or release balances from the allowance for loan losses. The Company’s allowance for loan losses is sensitive to risk ratings assigned to the individually evaluated loans and economic assumptions and delinquency trends driving statistically modeled reserves. Individual loan risk ratings are evaluated based on each situation by experienced senior credit officers. ​ Management monitors differences between estimated and actual incurred loan losses. This monitoring process includes periodic assessments by senior management of loan portfolios and the models used to estimate incurred losses in those portfolios. Additions to the allowance for loan losses are made by changes to the provision for loan losses. Credit exposures deemed to be uncollectible are charged against the allowance for loan losses. Recoveries of previously charged off amounts are credited to the allowance for loan losses. ​ A loan is considered impaired when, based on current information and events, the Company has concerns about the ability to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. ​ The specific allowance component is used to individually establish an allowance for loans identified for impairment testing. When impairment is identified, a specific reserve may be established based on the Company’s calculation of the estimated loss embedded in the individual loan. Impairment testing includes consideration of the borrower’s overall financial condition, resources and payment record, support available from financial guarantors and the fair market value of the collateral. These factors are combined to estimate the probability and severity of inherent losses. Large groups of smaller balance, homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately evaluate individual consumer and residential loans for impairment. ​ The pooled formula component is used to estimate the losses inherent in the pools of non-classified loans. These loans are then also segregated by loan type and allowance factors are assigned by management based on delinquencies, loss history, trends in volume and terms of loans, effects of changes in lending policy, the experience and depth of management, national and local economic trends, concentrations of credit, results of the loan review system and the effect of external factors (i.e. competition and regulatory requirements). Current economic conditions take into account the average unemployment rate for St. Lawrence, Jefferson and Lewis Counties, New York, the State of New York and for the nation, with the most significance given to the St. Lawrence County data. The allowance factors assigned differ by loan type. ​ Allowance factors and overall size of the allowance may change from period to period based on management’s assessment of the above-described factors and the relative weights given to each factor. In addition, various regulatory agencies periodically review the allowance for loan losses. These agencies may require the Bank to make additions to the allowance for loan losses based on their judgments of collectability based on information available to them at the time of their examination. ​ Loans are placed into a non-accruing status and classified as nonperforming when the principal or interest has been in default for a period of 90 days or more unless the obligation is well secured and in the process of collection. A debt is “well secured” if it is secured by (1) pledges of real or personal property, including securities, that have a realizable value sufficient to discharge the debt (including accrued interest) in full, or (2) the guarantee of a financially responsible party. A debt is “in the process of collection” if collection on the debt is proceeding in due course either through legal action, including judgment enforcement procedure, or, in appropriate circumstances, through collection efforts not involving legal action which are reasonably expected to result in repayment of the debt or in its restoration to a current status. ​ Loans classified as substandard or worse are considered for impairment testing. A substandard loan shows signs of continuing negative financial trends and unprofitability, and therefore is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. The borrower on such loans typically exhibits one or more of the following characteristics: financial ratios and profitability margins are well below industry average; a negative cash flow position exists; debt service capacity is insufficient to the service debt and an improvement in the cash flow position is unlikely within the next twelve months; secondary and tertiary means of debt repayment are weak. Loans classified as substandard are characterized by the probability that the Bank will not collect amounts due according to the contractual terms or will sustain some loss if the deficiencies are not corrected. ​ Loss potential, while existing with respect to the aggregate amount of substandard (or worse) loans, does not have to exist in any individual assets classified as substandard. Such credits are also evaluated for nonaccrual status. ​ Impaired loans include loans that have been classified as substandard or worse. However, certain loans have been paying as agreed and have remained current, with some financial issues related to cash flow that have caused some concern as to the ability of the borrower to perform in accordance with the current loan terms but not to such extent as to require the loan to be put into a non-accruing status. Cash receipts on impaired loans are recorded as interest income as received, unless the loan is in a nonaccrual status. ​ The Company’s charge-off policies by segment of the loan portfolio are as follows: ​ ● Real Estate – The Company generally writes down to the net realizable value based on new appraisal values obtained at the time of possession. ● Consumer Loans – The Company generally fully or partially charges down to the net realizable value at the time of possession. ● Commercial Loans – The Company reviews on a quarterly basis.
Premises and Equipment	Premises and Equipment ​ Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. Costs of significant property improvements are capitalized. Maintenance and repairs are expensed as incurred, while major additions and improvements are capitalized. Gains and losses on dispositions are included in current earnings. Depreciation expense is calculated principally on the straight-line method over the following estimated useful lives of the related assets: ​ ​ ​ ​ ​ Years ​ ​ ​ Buildings and Improvements 5 - 39.5 Furniture and Equipment 3 - 7
Foreclosed Assets	Foreclosed Assets ​ Foreclosed assets include both formally foreclosed property and in-substance foreclosed property. In-substance foreclosed properties are those properties for which the institution has taken physical possession, regardless of whether formal foreclosure proceedings have taken place. ​ At the time of foreclosure, foreclosed assets are recorded at the fair value less cost to sell, which becomes the property’s new basis. Any write-downs based on the asset’s fair value at date of acquisition are charged to the allowance for loan losses. After foreclosure, management performs periodic valuations and property held for sale is carried at the lower of the new cost basis or fair value less cost to sell. Gains and losses realized on the sale, and any adjustments resulting from periodic re-evaluation of the property are included in noninterest income or expense, as appropriate. Net costs of maintaining and operating the properties are expensed as incurred. Improvements, which extend the life or improve the value of the property, are capitalized as incurred.
Transfers of Financial Assets	Transfers of Financial Assets ​ Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free from conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before maturity.
Investment in Life Insurance	Investment in Life Insurance ​ The Company purchased single-premium life insurance on certain employees and executives of the Company and is carried at its cash surrender value. Appreciation in value of the life insurance policies and gain on death proceeds are classified as noninterest income. The cash surrender value received from death proceeds is recorded as a reduction to the carrying value.
Income Taxes	Income Taxes ​ The Company files a consolidated federal income tax return. Provisions for income taxes are based on taxes payable or refundable for the current year and deferred taxes on temporary differences between the amount of taxable income and pretax financial income. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. ​ Under Financial Accounting Standards Board Accounting Standard Codification (“FASB ASC”), “Accounting for Income Taxes,” the Company recognizes potential liabilities associated with anticipated tax audit issues that may arise during an examination. Interest and penalties that are anticipated to be due upon examination are recognized as accrued interest and other liabilities with an offset to interest and other expense. The Company determined that there were no uncertainties with respect to the application of tax regulations.
Advertising Costs	Advertising Costs ​ The Company follows the policy of charging the costs of advertising to expense as incurred. Advertising expense, included in other non-interest expenses, was approximately $103,000 and $80,000 at September 2023 and 2022, respectively.
Fair Value Measurements	Fair Value Measurements ​ The Company follows the guidance of FASB ASC 820, Fair Value Measurements and Disclosures. This guidance permits entities to measure many financial instruments and certain other items at fair value. The objective is to improve financial reporting by providing entities with the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. This guidance clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Under this guidance, fair value measurements are not adjusted for transaction costs. The guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).
Earnings per Common Share	Earnings per Common Share ​ Basic earnings per common share represents income available to common shareholders divided by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflect additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. ​ The following table sets forth the computations of basic and diluted earnings per common share for the years ended September 30 (In Thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ 2023 2022 ​ ​ (In Thousands, except per share data) ​ ​ ​ ​ ​ ​ ​ Net Earnings ​ $ 317 ​ $ 1,527 ​ ​ ​ ​ ​ ​ ​ Basic Earnings Per Common Share, ​ ​ ​ ​ ​ ​ Weighted Average Shares ​ ​ 2,031 ​ ​ 2,031 ​ ​ ​ ​ ​ ​ ​ Diluted Earnings per Common Share, ​ ​ ​ ​ ​ ​ Adjusted Weighted Average Shares ​ ​ 2,031 ​ ​ 2,031 ​ ​ ​ ​ ​ ​ ​ Basic and Diluted Earnings Per Common Share ​ $ 0.16 ​ $ 0.75 ​ There were no dilutive or antidilutive shares at September 30, 2023 or 2022. ​ At September 30, 2023 and 2022, the Company had 352,231 and 352,233 shares of treasury stock, respectively. There were 2 shares of stock retired during the first quarter of fiscal year 2023.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities ​ All derivative financial instruments are reported at their fair value either as assets or liabilities. The Company reports net derivatives in a gain position, or derivative assets in the consolidated statements of financial condition as a component of other assets. The Company reports net derivatives in a loss position, or derivative liabilities, in the consolidated statements of financial position as a component of other liabilities.
Revenue Recognition	Revenue Recognition ​ The majority of the Company’s revenue stream is generated from interest income on loans and deposits which are outside the scope of “ Revenue from Contracts with Customers”   ​ The Company’s sources of income that fall within the scope of Topic 606 include service charges on deposits, interchange fees and gains and losses on sales of other real estate, all of which are presented as components of noninterest income. Below is a summary of the revenue streams that fall within the scope of Topic 606. ​ Service charges on deposits, ATM, and interchange fees ​ Gains and losses on sales of other real estate – the sale of OREO to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer.
Valuation of Long-Lived Assets	Valuation of Long-Lived Assets ​ The Company accounts for the valuation of long-lived assets under FASB ASC 360, Property, Plant and Equipment. This guidance requires that long-lived assets and certain identifiable intangible assets be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of the long-lived asset is measured by a comparison of the carrying amount of the asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the estimated fair value of the assets. Assets to be disposed of are reportable at the lower of the carrying amount or fair value, less costs to sell.
Comprehensive Loss	Comprehensive Loss ​ Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net earnings. Although certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale securities, and the changes in the funded status of pension and post-retirement benefits, are reported as a separate component of the equity section of the consolidated statements of financial condition, such items, along with net earnings, are components of comprehensive loss. ​ Accumulated other comprehensive loss represents the sum of these items, with the exception of net earnings, as of September 30, represented in the table below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended ​ ​ September 30, ​ ​ ​ ​ ​ ​ ​ ​ ​ 2023 ​ 2022 Accumulated Other Comprehensive Loss by Component ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Unrealized Loss for Other Postretirement Obligations ​ $ (326) $ (773) Tax Effect ​ 69 ​ 162 Net Unrealized Loss for Other Postretirement Obligations ​ ​ (257) ​ ​ (611) ​ ​ ​ ​ ​ ​ ​ Unrealized Loss on Available-for-Sale Securities, net ​ ​ (4,890) ​ (4,654) Tax Effect ​ 1,024 ​ 977 Net Unrealized Loss on Available-for-Sale Securities ​ (3,866) ​ (3,677) ​ ​ ​ ​ ​ ​ ​ Total Comprehensive Loss ​ $ (4,123) ​ $ (4,288)
Off-Balance Sheet Credit Related Financial Instruments	Off-Balance Sheet Credit Related Financial Instruments ​ In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under commercial and home equity lines of credit. Such financial instruments are recorded when they are funded.
Reclassification	Reclassification ​ Certain accounts in the prior-year consolidated financial statements have been reclassified for comparative purposes to conform with the presentation in the current-year consolidated financial statements.
Adoption of Recently Issued Accounting Standards and Impact of Recent Accounting Pronouncements	Adoption of Recently Issued Accounting Standards On October 1, 2022, the Company adopted ASU 2021-10 related to guidance on “Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistances”, which aims to provide increased transparency by requiring business entities to disclose information about certain types of government assistance they receive in the notes to the financial statements. Current GAAP has no specific authoritative guidance on the accounting for, or the disclosure of, government assistance received by business entities. The amendments in this Update improve financial reporting by requiring disclosures that increase the transparency of transactions with a government accounted for by applying a grant or contribution accounting model by analogy, including (1) the types of transactions, (2) the accounting for those transactions, and (3) the effect of those transactions on an entity’s financial statements. The Company believes this has no significant impact on the consolidated financial statement and related disclosures. In February 2016, the Financial Accounting Standards Board (the “FASB”) issued ASU 2016-02 to its guidance on “Leases (Topic 842)”. The new leases standard applies a right-of-use (ROU) model that requires a lessee to record, for all leases with a lease term of more than 12 months, an asset representing its right to use the underlying asset and a liability to make lease payments. For leases with a term of 12 months or less, a practical expedient is available whereby a lessee may elect, by class of underlying asset, not to recognize an ROU asset or lease liability. The new leases standard requires a lessor to classify leases as either sales-type, direct financing or operating, similar to existing GAAP. Classification depends on the same five criteria used by lessees plus certain additional factors. The subsequent accounting treatment for all three lease types is substantially equivalent to existing GAAP for sales-type leases, direct financing leases, and operating leases. However, the new standard updates certain aspects of the lessor accounting model to align it with the new lessee accounting model, as well as with the new revenue standard under Topic 606. Lessees and lessors are required to provide certain qualitative and quantitative disclosures to enable users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The adoption of this ASU will result in a gross up of the Consolidated Statements of Condition for right-of-use assets and associated lease liabilities for operating leases in which the Company is the lessee. In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842 - Leases to address certain narrow aspects of the guidance issued in ASU No. 2016-02. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, which amends FASB Accounting Standards Codification (ASC), Leases (Topic 842), to (1) add an optional transition method that would permit entities to apply the new requirements by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the year of adoption, and (2) provide a practical expedient for lessors regarding the separation of the lease and non-lease components of a contract. In December 2018, the FASB issued ASU No. 2018-20, Narrow-Scope Improvements for Lessors, which addresses issues related to (1) sales tax and similar taxes collected from lessees, (2) certain lessor costs, and (3) recognition of variable payments for contracts with lease and non-lease components. In June 2020, the FASB issued No. ASU 2020-05, Coronavirus Disease 2019 (“COVID-19”) in response to the pandemic which has adversely affected the global economy and caused significant and widespread business and capital market disruptions. The FASB is committed to supporting and assisting stakeholders during this difficult time. The FASB issued ASU 2020-05 as a limited deferral of the effective dates of certain ASUs, including ASU 2016-02 (including amendments issued after the issuance of the original) to provide immediate, near-term relief for certain entities for whom these ASUs are either currently effective or imminently effective. The Company plans to defer the adoption of the amendments in ASU 2016-02 to the fiscal year beginning October 1, 2022. The Company is evaluating the significance and other effects of adoption on the consolidated financial statements and related disclosures. The Company is performing its accounting analysis of its branch building and other leases underlying contracts. At October 1, 2022, the Company recognized right of use operating leases valued at approximately $43,000. Impact of Recent Accounting Pronouncements On October 1, 2023, the Company adopted ASU 2016 13 related 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 unless reasonable expectation of a troubled debt restructuring exists) 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 available-for-sale (AFS) debt securities. 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. The amendments in this ASU were effective for the Company for the fiscal year beginning October 1, 2023. An entity will apply the amendments in this ASU 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. ASU 2019-04 clarifies or addresses stakeholders’ specific issues about certain aspects of the amendments in Update 2016-13 related to measuring the allowance for loan losses under the new guidance. 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 clarifying certain amendments to various provisions of ASU No. 2016-13 relating to (1) purchased financial assets with credit deterioration, (2) financial assets secured by collateral maintenance agreements, (3) transition relief for troubled debt restructurings, and (4) disclosure relief when the practical expedient for accrued interest receivables is applied. In March 2022, the FASB issued ASU 2022-02, Codification Improvements to Topic 326, Financial Instruments Credit Losses, which eliminates the accounting guidance for troubled debt restructurings by creditors that have adopted the CECL model and enhances the disclosure requirements for loan refinancings and restructurings made with borrowers experiencing financial difficulty. In addition, the amendments require a public business entity to disclose current-period gross write-offs for financing receivables and net investment in leases by year of origination in the vintage disclosures. The initial adjustment for the reserve made on October 1, 2023 was for $465,000. Although this adjustment was not reported in earnings and therefore will not have any material impact on our consolidated results of operations, it did make an impact on our consolidated financial position at the date of adoption of this ASU. On adoption date, $367,350 of the adjustment was recognized in retained earnings, with the remaining $97,650 recognized in deferred tax assets. On October 1, 2023, the Company adopted ASU 2019-12, Income Taxes Topic 740. This update simplifies and improves accounting for income taxes by eliminating certain exceptions to the general rules and clarifying or amending other current guidance. The scope of FASB ASC Subtopic 740-10, Income Taxes -Overall, has been amended to require that, if a franchise (or similar tax) is partially based on income, (1) deferred tax assets and liabilities should be recognized and accounted for pursuant to FASB ASC 740, as should the amount of current tax expense that is based on income, and (2) any incremental amount incurred should be recorded as a non-income-based tax. Note that under the amended guidance, the effect of potentially paying a non-income-based tax in future years need not be considered in evaluating the realizability of deferred tax assets. The amendments in this ASU were effective for the Company for the fiscal year beginning October 1, 2023. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848). The amendments in this update provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this update 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 ASU are effective for all entities as of March 12, 2020 through December 31, 2022. The amendments for contract modifications can be elected to be applied as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020. The amendments for existing hedging relationships can be elected to be applied as of the beginning of the interim period that includes March 12, 2020 and to new eligible hedging relationships entered into after the beginning of the interim period that includes March 12, 2020. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform to clarify that all derivative instruments affected by changes to the interest rates used for discounting, margining or contract price alignment are in scope of Topic 848. ASU 2021-01 expands the scope of ASU 2020-04 by allowing an entity to apply the optional expedients, by stating that a change to the interest rate used for margining, discounting or contract price alignment for a derivative is not considered to be a change to the critical terms of the hedging relationship that requires dedesignation. The Company has signed an amended agreement with Federal Home Loan Bank of New York for the transition to SOFR which began July 1, 2023.
Core Deposit Intangible (CDI)	Core Deposit Intangible (CDI) The core deposit intangible resulted from the acquisition of Citizens Bank of Cape Vincent (“CBCV”), a commercial bank with full-service offices in Cape Vincent, Chaumont, and LaFargeville, New York. The acquisition was consummated at the end of business on September 16, 2022. The CDI for CBCV is amortized based on cash flow streams based upon the selected attrition rates and run off assumptions calculated to represent the result of acquiring like-costing deposits versus the cost of alternative funding vehicles over a 10-year
Goodwill	Goodwill Goodwill represents the excess cost of the acquisition of CBCV over the fair value of assets acquired. Goodwill is not amortized, but evaluated annually for impairment.
