BASIS OF PRESENTATION, RISKS AND UNCERTAINTIES, ACCOUNTING POLICIES AND RECENT ACCOUNTING DEVELOPMENTS	1. BASIS OF PRESENTATION, RISKS AND UNCERTAINTIES, ACCOUNTING POLICIES AND RECENT ACCOUNTING DEVELOPMENTS Hanover Bancorp, Inc. (the “Company”), is a New York corporation which became the holding company for Hanover Community Bank (the “Bank”) in 2016. The Bank, headquartered in Mineola, New York, is a New York State chartered bank. The Bank commenced operations on November 4, 2008 and is a full-service bank providing personal and business lending and deposit services. As a New York State chartered, non-Federal Reserve member bank, the Bank is subject to regulation by the New York State Department of Financial Services (“DFS”) and the Federal Deposit Insurance Corporation (“FDIC”). The Company is subject to regulation and examination by the Board of Governors of the Federal Reserve System (the “FRB”). Basis of Presentation In the opinion of the Company’s management, the preceding unaudited interim consolidated financial statements contain all adjustments, consisting of normal accruals, necessary for a fair presentation of the Company’s consolidated statement of financial condition as of June 30, 2022, its consolidated statements of income for the three and nine months ended June 30, 2022 and 2021, its consolidated statements of comprehensive income for the three and nine months ended June 30, 2022 and 2021, its consolidated statements of changes in stockholders’ equity for the three and nine months ended June 30, 2022 and 2021 and its consolidated statements of cash flows for the nine months ended June 30, 2022 and 2021. Certain prior period amounts have been reclassified to conform to the current period presentation. In addition, the preceding unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X, as well as in accordance with predominant practices within the banking industry. They do not include all the information and footnotes required by U.S. GAAP for complete financial statements. The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and the accompanying notes. Actual results could differ from those estimates. The results of operations for the three and nine months ended June 30, 2022 are not necessarily indicative of the results of operations to be expected for the remainder of the year. The unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2021. All material intercompany accounts and transactions have been eliminated in consolidation. Unless the context otherwise requires, references herein to the Company include the Company and the Bank on a consolidated basis. Risks and Uncertainties In March 2020, the World Health Organization declared the outbreak of COVID-19 a global pandemic. The COVID-19 pandemic has adversely affected local, national and global economic activity. Various actions taken to help mitigate the spread of COVID-19 included restrictions on travel, quarantines and government-mandated closures of various businesses. The outbreak caused significant disruptions to the economy and disrupted banking and other financial activity in the areas in which the Company operates. The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted in March 2020 to, among other things, provide emergency assistance to individuals, families and businesses affected by the COVID-19 pandemic. The ongoing effects of the COVID-19 pandemic may materially and adversely affect the Company’s financial condition and results of operations in future periods, and it is unknown what the complete financial impact will be to the Company. The extent of such impact will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the coronavirus, the new “waves” of COVID-19 infections, the spread of new variants of the virus, and the distribution of vaccines and vaccination rates, among others. It is possible that estimates made in the financial statements could be materially and adversely impacted due to these conditions. Accounting Policies Allowance for Loan Losses Loans and Loan Interest Income Recognition Interest income on loans is accrued and credited to income as earned. Net loan origination fees and costs are deferred and accreted/amortized to interest income over the loan’s contractual life using the level-yield method, adjusted for actual prepayments. Loans that are acquired are initially recorded at fair value with no carryover of the related allowance for loan losses. After acquisition, losses are recognized through the allowance for loan losses. Determining the fair value of the loans involves estimating the amount and timing of expected principal and interest cash flows to be collected on the loans and discounting those cash flows at a market interest rate. At June 30, 2022 and September 30, 2021, the Company had loans totaling $1.2 million and $10.2 million, respectively, which at the time of acquisition, showed evidence of credit deterioration since origination. Loans Held for Sale For liquidity purposes generally, there are instances when loans originated with the intent to hold in the portfolio are subsequently transferred to loans held for sale. At transfer, they are carried at the lower of cost or fair value. ​ Recent Accounting Developments In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02, Leases. The amendments in this update primarily replace the existing accounting requirements for operating leases for lessees. Lessee accounting requirements for finance leases and lessor accounting requirements for operating leases and sales type and direct financing leases (sales-type and direct financing leases were both previously referred to as capital leases) are largely unchanged. The amendments require the lessee of an operating lease to record a balance sheet gross-up upon lease commencement by recognizing a right-of-use asset and lease liability equal to the present value of the lease payments. The right-of-use asset and lease liability should be derecognized in a manner that effectively yields a straight-line lease expense over the lease term. In addition to the changes to the lessee operating lease accounting requirements, the amendments also change the types of costs that can be capitalized related to a lease agreement for both lessees and lessors. The amendments also require additional disclosures for all lease types for both lessees and lessors. The FASB has subsequently issued additional ASUs intended to clarify guidance, provide implementation support, and provide an additional transition election. The amendments are effective on October 1, 2022, with early adoption permitted. The amendments must be applied on a modified retrospective basis, and we anticipate selecting the transition option that will allow us to record a cumulative adjustment as of the adoption date. We are assessing our current population of lease contracts and upon adoption, our balance sheet will include a right-of-use asset and lease liability for our operating leases where we are the lessee, which primarily include our facilities leases. We do not anticipate the adoption of these amendments will have a material impact to our consolidated financial statements. We plan to adopt these amendments on October 1, 2022 and expect to use the modified retrospective approach as currently required.

EARNINGS PER COMMON SHARE	3. EARNINGS PER COMMON SHARE Basic earnings per common share is computed based on the weighted-average number of shares outstanding. Diluted earnings per common share includes the dilutive effect of additional potential common shares issuable under stock options. For periods in which a loss is reported, the impact of stock options is not considered as the result would be antidilutive. The computation of earnings per common share for the three and nine months ended June 30, 2022 and 2021 follows.

Troubled debt restructurings (“TDRs”) are loan modifications where the Company has granted a concession to a borrower in financial difficulty. To assess whether a borrower is experiencing financial difficulty, an evaluation is performed to determine if that borrower is currently in payment default under any of its obligations or whether there is a probability that the borrower will be in payment default in the foreseeable future without the modification. At June 30, 2022 and September 30, 2021, the Company had a recorded investment in TDRs totaling $1.3 million and $1.6 million, consisting solely of residential real estate loans with no specific reserves allocated to such loans and no commitment to lend additional funds under those loans, at either June 30, 2022 or September 30, 2021. For the three and nine months ended June 30, 2022 and 2021, there were no TDRs for which there was a payment default within twelve months of restructuring. A loan is considered to be in payment default once it is 90 days contractually past due under its modified terms. For the three and nine months ended June 30, 2022 and 2021, the Company had no new TDRs. The Company continuously monitors the credit quality of its loan receivables. Credit quality is monitored by reviewing certain credit quality indicators. Management has determined that internally assigned credit risk ratings by loan segment are the key credit quality indicators that best assist management in monitoring the credit quality of the Company’s loan receivables. The Company has adopted a credit risk rating system as part of the risk assessment of its loan portfolio. The Company’s lending officers are required to assign a credit risk rating to each loan in their portfolio at origination. When the lender learns of important financial developments, the risk rating is reviewed and adjusted if necessary. In addition, the Company engages a third-party independent loan reviewer that performs quarterly reviews of a sample of loans, validating the credit risk ratings assigned to such loans. The credit risk ratings play an important role in the establishment of the loan loss provision and to confirm the adequacy of the allowance for loan losses. The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes commercial loans individually by classifying the loans as to credit risk. The Company uses the following definitions for risk ratings: Special Mention: Substandard: Doubtful: Loans not having a credit risk rating of Special Mention, Substandard or Doubtful are considered pass loans. At June 30, 2022 and September 30, 2021, the Company’s loan portfolio by credit risk rating disaggregated by portfolio segment were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2022 ​ ​ ​ Special ​ ​ ​ ​ ​ ​ (in thousands) ​ Pass ​ Mention ​ Substandard ​ Doubtful ​ Total Real Estate: ​ ​ ​ ​ ​ Residential ​ $ 426,257 ​ $ 516 ​ $ 4,636 ​ $ — ​ $ 431,409 Multi-family ​ 473,592 ​ 2,821 ​ 2,343 ​ — ​ 478,756 Commercial ​ 412,834 ​ 8,818 ​ 8,301 ​ — ​ 429,953 Commercial and industrial ​ 53,811 ​ 637 ​ 2,096 ​ — ​ 56,544 Construction and land development ​ 14,806 ​ 2,408 ​ — ​ — ​ 17,214 Consumer ​ 12 ​ — ​ — ​ — ​ 12 Total ​ $ 1,381,312 ​ $ 15,200 ​ $ 17,376 ​ $ — ​ $ 1,413,888 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2021 ​ ​ ​ Special ​ ​ ​ ​ ​ ​ (in thousands) ​ Pass ​ Mention ​ Substandard ​ Doubtful ​ Total Real Estate: ​ ​ ​ ​ ​ Residential ​ $ 433,299 ​ $ 5,115 ​ $ 5,594 ​ $ 3 ​ $ 444,011 Multi-family ​ 262,984 ​ 2,852 ​ 458 ​ — ​ 266,294 Commercial ​ 316,727 ​ 16,274 ​ 15,640 ​ — ​ 348,641 Commercial and industrial ​ 168,104 ​ 540 ​ 3,630 ​ — ​ 172,274 Construction and land development ​ 13,607 ​ 1,767 ​ — ​ — ​ 15,374 Consumer ​ 11 ​ — ​ — ​ — ​ 11 Total ​ $ 1,194,732 ​ $ 26,548 ​ $ 25,322 ​ $ 3 ​ $ 1,246,605 ​

EQUITY COMPENSATION PLANS
EQUITY COMPENSATION PLANS	6. EQUITY COMPENSATION PLANS The Company’s 2021 and 2018 Equity Compensation Plans (the “2021 Plan” and the “2018 Plan”, respectively), provide for the grant of stock-based compensation awards to members of management, including employees and management officials, and members of the Board. Under the 2021 Plan, a total of 427,500 shares of the Company’s common stock or equivalents were approved for issuance, of which 274,208 shares remain available for issuance at June 30, 2022. Of the total 346,000 shares of common stock approved for issuance under the 2018 Plan, 32,802 shares remain available for issuance at June 30, 2022. Hanover assumed the 2013 Savoy Bank Stock Option Plan solely in connection with options to purchase Savoy common stock held by the former Chief Executive Officer of Savoy and which, under the terms of the Agreement and Plan of Merger between the Company and Savoy, were converted into options to purchase 71,900 shares of Hanover common stock. Stock Options Stock options are granted with an exercise price equal to the fair market value of the Company’s common stock at the date of grant, and generally with vesting periods of three years and contractual terms of ten years. All stock options fully vest upon a change in control. The fair value of stock options is estimated on the date of grant using a closed form option valuation (Black-Scholes) model. Expected volatilities are based on historical volatilities of the common stock of the Company’s peers. The Company uses historical data to estimate option exercise and post-vesting termination behavior. Expected terms are based on historical data and represent the periods in which the options are expected to be outstanding. The risk-free interest rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of grant. No stock options were exercised during the three and nine months ended June 30, 2022 and 2021. A summary of stock option activity follows (aggregate intrinsic value in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted ​ ​ ​ ​ Weighted ​ ​ ​ ​ Average ​ ​ ​ ​ Average ​ Aggregate ​ Remaining ​ ​ Number of ​ Exercise ​ Intrinsic ​ Contractual ​ Options Price Value Term Outstanding, October 1, 2021 227,406 ​ $ 9.50 ​ $ 2,043 3.51 years Granted — ​ — ​ ​ ​ Exercised — ​ — ​ ​ ​ Forfeited — ​ — ​ ​ ​ Outstanding, June 30, 2022 (1) 227,406 ​ $ 9.50 ​ $ 2,400 2.70 years (1) All outstanding options are fully vested and exercisable. There was no compensation expense attributable to stock options for the three and nine months ended June 30, 2022 and 2021. Restricted Stock Awards During the nine months ended June 30, 2022, restricted stock awards of 44,642 shares were granted with a three-year vesting period and 230,788 were granted with a five-year vesting period. Compensation expense is recognized over the vesting period of the awards based on the fair value of the stock at issue date. A summary of restricted stock awards activity follows: ​ ​ ​ ​ ​ ​ ​ ​ Weighted-Average ​ ​ Number of ​ Grant Date Fair ​ Shares Value Unvested, October 1, 2021 ​ 75,833 ​ $ 19.87 Granted 275,430 ​ 19.73 Vested (41,504) ​ 19.77 Forfeited (10,189) ​ 19.47 Unvested, June 30, 2022 299,570 ​ $ 19.77 ​ Compensation expense attributable to restricted stock awards was $482 thousand and $224 thousand for the three months ended June 30, 2022 and 2021, respectively. Compensation expense attributable to restricted stock was $1.1 million and $669 thousand for the nine months ended June 30, 2022 and 2021, respectively. As of June 30, 2022, there was $5.3 million of total unrealized compensation cost related to unvested restricted stock, expected to be recognized over a weighted-average term of 4.12 years. The total fair value of shares vested during the nine months ended June 30, 2022 and 2021 was $824 thousand and $868 thousand, respectively. ​ Restricted Stock Units Long Term Incentive Plan ​ Restricted stock units (RSUs) represent an obligation to deliver shares to a grantee at a future date if certain vesting conditions are met. RSUs are subject to a time-based vesting schedule, and/or the satisfaction of performance conditions, and are settled in shares of the Company's common stock. RSUs do not provide voting rights and RSUs may accrue dividends from the date of grant. ​ The following table summarizes the unvested performance-based RSU activity for the nine months ended June 30, 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted-Average ​ ​ Number of ​ Grant Date Fair ​ Shares Value Unvested, October 1, 2021 ​ — ​ $ — Granted 51,097 ​ 19.73 Vested — ​ — Forfeited — ​ — Unvested, June 30, 2022 51,097 ​ $ 19.73 ​ During the nine months ended June 30, 2022, the Company granted 51,097 RSUs. These performance-based RSUs cliff vest after three years and are subject to the achievement of the Company's pre-defined performance goals for the three-year period ending December 31, 2024. ​ Compensation expense attributable to RSUs was $82 thousand and $139 thousand, respectively, for the three and nine months ended June 30, 2022. There was no compensation expense related to RSUs for the three and nine months ended June 30, 2021, as no RSUs were granted in 2021. As of June 30, 2022, there was $869 thousand of total unrecognized compensation cost related to non-vested RSUs. The cost is expected to be recognized over a weighted-average period of 2.7 years.

REGULATORY MATTERS
REGULATORY MATTERS	7. REGULATORY MATTERS The Bank is subject to various regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet minimum capital requirements can initiate regulatory action. The net unrealized gain or loss on available for sale securities is not included in computing regulatory capital. Management believes as of June 30, 2022, the Bank meets all capital adequacy requirements to which it is subject. Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized or worse, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. At June 30, 2022 and September 30, 2021, the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the institution’s category. Under a policy of the Federal Reserve applicable to bank holding companies with less than $3.0 billion in consolidated assets, the Company is not subject to consolidated regulatory capital requirements. The following table sets forth the Bank’s capital amounts (in thousands) and ratios under current regulations: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Minimum Capital ​ Minimum to Be Well ​ ​ ​ ​ ​ ​ Adequacy Requirement ​ Capitalized Under ​ ​ ​ ​ Minimum Capital ​ with Capital ​ Prompt Corrective ​ ​ Actual Capital ​ Adequacy Requirement ​ Conservation Buffer ​ Action Provisions ​ Amount Ratio Amount Ratio Amount Ratio Amount Ratio June 30, 2022 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total capital to risk-weighted assets ​ $ 182,811 17.32 % $ 84,444 8.00 % $ 110,833 10.50 % $ 105,555 10.00 % Tier 1 capital to risk-weighted assets ​ 171,753 16.27 % 63,333 6.00 % 89,722 8.50 % 84,444 8.00 % Common equity tier 1 capital to risk-weighted assets ​ 171,753 16.27 % 47,500 4.50 % 73,889 7.00 % 68,611 6.50 % Tier 1 capital to adjusted average assets (leverage) ​ 171,753 11.64 % 59,007 4.00 % N/A N/A ​ 73,759 5.00 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total capital to risk-weighted assets ​ $ 132,554 15.59 % $ 68,040 ​ 8.00 % $ 89,303 10.50 % $ 85,050 10.00 % Tier 1 capital to risk-weighted assets ​ 123,666 14.54 % ​ 51,030 ​ 6.00 % ​ 72,293 8.50 % ​ 68,040 8.00 % Common equity tier 1 capital to risk-weighted assets ​ 123,666 14.54 % ​ 38,273 ​ 4.50 % ​ 59,535 7.00 % ​ 55,283 6.50 % Tier 1 capital to adjusted average assets (leverage) ​ 123,666 9.45 % ​ 52,338 ​ 4.00 % ​ N/A N/A ​ ​ 65,423 5.00 % ​ Dividend restrictions - The Company’s principal source of funds for dividend payments is dividends received from the Bank.

FAIR VALUE

FAIR VALUE
FAIR VALUE	8. FAIR VALUE FASB ASC No. 820-10 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined using quoted market prices. However, in many instances, quoted market prices are not available. In such instances, fair values are determined using appropriate valuation techniques. Various assumptions and observable inputs must be relied upon in applying these techniques. Accordingly, categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. As such, the fair value estimates may not be realized in an immediate transfer of the respective asset or liability. FASB ASC 820-10 also establishes a fair value hierarchy and describes three levels of inputs that may be used to measure fair values: The three levels within the fair value hierarchy are as follows: ● Level 1: Valuation is based upon unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. ● Level 2: Fair value is calculated using significant inputs other than quoted market prices that are directly or indirectly observable for the asset or liability. The valuation may rely on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in inactive markets, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, rate volatility, prepayment speeds, credit ratings,) or inputs that are derived principally or corroborated by market data, by correlation, or other means. ● Level 3: Inputs for determining the fair value of the respective assets or liabilities are not observable. Level 3 valuations are reliant upon pricing models and techniques that require significant management judgment or estimation. Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing on- and off-balance-sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimates. ​ Assets Measured at Fair Value on a Recurring Basis The following presents fair value measurements on a recurring basis at June 30, 2022 and September 30, 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2022 ​ ​ ​ ​ Fair Value Measurements Using: ​ ​ ​ ​ Quoted Prices In ​ ​ ​ Significant ​ ​ Active Markets Significant Other Unobservable ​ ​ Carrying ​ for Identical Assets ​ Observable Inputs ​ Inputs (In thousands) ​ Amount ​ (Level 1) ​ (Level 2) ​ (Level 3) Financial assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Available-for-sale securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. GSE residential mortgage-backed securities ​ $ 319 ​ $ — ​ $ 319 ​ $ — Corporate bonds ​ 6,421 ​ — ​ 6,421 ​ — Mortgage servicing rights ​ 4,120 ​ — ​ — ​ 4,120 Total ​ $ 10,860 ​ $ — ​ $ 6,740 ​ $ 4,120 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2021 ​ ​ ​ ​ Fair Value Measurements Using: ​ ​ ​ ​ Quoted Prices In ​ ​ ​ ​ ​ ​ ​ ​ Active Markets ​ ​ ​ Significant ​ ​ for Identical Significant Other Unobservable ​ ​ Carrying ​ Assets ​ Observable Inputs ​ Inputs (In thousands) ​ Amount ​ (Level 1) ​ (Level 2) ​ (Level 3) Financial assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Available-for-sale securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. GSE residential mortgage-backed securities ​ $ 833 ​ $ — ​ $ 833 ​ $ — Corporate bonds ​ 6,914 ​ — ​ 6,914 ​ — Mortgage servicing rights ​ 3,690 ​ — ​ — ​ 3,690 Total ​ $ 11,437 ​ $ — ​ $ 7,747 ​ $ 3,690 ​ The fair value for the securities available-for-sale were obtained from an independent broker based upon matrix pricing, which is a mathematical technique widely used in the industry to value 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. The Company has determined these are classified as Level 2 inputs within the fair value hierarchy. The fair value of mortgage servicing rights are based on a valuation model that calculates the present value of estimated future servicing income. The valuation model utilizes interest rate, prepayment speed, and default rate assumptions that market participants would use in estimating future net servicing income. The fair value of loan servicing rights related to residential mortgage loans at June 30, 2022 was determined based on discounted expected future cash flows cash flows The fair value of loan servicing rights for SBA loans at June 30, 2022 was determined based on discounted expected future cash flows The Company has determined these are mostly unobservable inputs and considers them Level 3 inputs within the fair value hierarchy.

Basis of Presentation	Basis of Presentation In the opinion of the Company’s management, the preceding unaudited interim consolidated financial statements contain all adjustments, consisting of normal accruals, necessary for a fair presentation of the Company’s consolidated statement of financial condition as of June 30, 2022, its consolidated statements of income for the three and nine months ended June 30, 2022 and 2021, its consolidated statements of comprehensive income for the three and nine months ended June 30, 2022 and 2021, its consolidated statements of changes in stockholders’ equity for the three and nine months ended June 30, 2022 and 2021 and its consolidated statements of cash flows for the nine months ended June 30, 2022 and 2021. Certain prior period amounts have been reclassified to conform to the current period presentation. In addition, the preceding unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X, as well as in accordance with predominant practices within the banking industry. They do not include all the information and footnotes required by U.S. GAAP for complete financial statements. The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and the accompanying notes. Actual results could differ from those estimates. The results of operations for the three and nine months ended June 30, 2022 are not necessarily indicative of the results of operations to be expected for the remainder of the year. The unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2021. All material intercompany accounts and transactions have been eliminated in consolidation. Unless the context otherwise requires, references herein to the Company include the Company and the Bank on a consolidated basis.
Risks and Uncertainties	Risks and Uncertainties In March 2020, the World Health Organization declared the outbreak of COVID-19 a global pandemic. The COVID-19 pandemic has adversely affected local, national and global economic activity. Various actions taken to help mitigate the spread of COVID-19 included restrictions on travel, quarantines and government-mandated closures of various businesses. The outbreak caused significant disruptions to the economy and disrupted banking and other financial activity in the areas in which the Company operates. The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted in March 2020 to, among other things, provide emergency assistance to individuals, families and businesses affected by the COVID-19 pandemic. The ongoing effects of the COVID-19 pandemic may materially and adversely affect the Company’s financial condition and results of operations in future periods, and it is unknown what the complete financial impact will be to the Company. The extent of such impact will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the coronavirus, the new “waves” of COVID-19 infections, the spread of new variants of the virus, and the distribution of vaccines and vaccination rates, among others. It is possible that estimates made in the financial statements could be materially and adversely impacted due to these conditions.
Allowance for Loan Losses	Allowance for Loan Losses
Loans and Loan Interest Income Recognition	Loans and Loan Interest Income Recognition Interest income on loans is accrued and credited to income as earned. Net loan origination fees and costs are deferred and accreted/amortized to interest income over the loan’s contractual life using the level-yield method, adjusted for actual prepayments. Loans that are acquired are initially recorded at fair value with no carryover of the related allowance for loan losses. After acquisition, losses are recognized through the allowance for loan losses. Determining the fair value of the loans involves estimating the amount and timing of expected principal and interest cash flows to be collected on the loans and discounting those cash flows at a market interest rate. At June 30, 2022 and September 30, 2021, the Company had loans totaling $1.2 million and $10.2 million, respectively, which at the time of acquisition, showed evidence of credit deterioration since origination.
Loans Held for Sale	Loans Held for Sale For liquidity purposes generally, there are instances when loans originated with the intent to hold in the portfolio are subsequently transferred to loans held for sale. At transfer, they are carried at the lower of cost or fair value.
Recent Accounting Developments	Recent Accounting Developments In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02, Leases. The amendments in this update primarily replace the existing accounting requirements for operating leases for lessees. Lessee accounting requirements for finance leases and lessor accounting requirements for operating leases and sales type and direct financing leases (sales-type and direct financing leases were both previously referred to as capital leases) are largely unchanged. The amendments require the lessee of an operating lease to record a balance sheet gross-up upon lease commencement by recognizing a right-of-use asset and lease liability equal to the present value of the lease payments. The right-of-use asset and lease liability should be derecognized in a manner that effectively yields a straight-line lease expense over the lease term. In addition to the changes to the lessee operating lease accounting requirements, the amendments also change the types of costs that can be capitalized related to a lease agreement for both lessees and lessors. The amendments also require additional disclosures for all lease types for both lessees and lessors. The FASB has subsequently issued additional ASUs intended to clarify guidance, provide implementation support, and provide an additional transition election. The amendments are effective on October 1, 2022, with early adoption permitted. The amendments must be applied on a modified retrospective basis, and we anticipate selecting the transition option that will allow us to record a cumulative adjustment as of the adoption date. We are assessing our current population of lease contracts and upon adoption, our balance sheet will include a right-of-use asset and lease liability for our operating leases where we are the lessee, which primarily include our facilities leases. We do not anticipate the adoption of these amendments will have a material impact to our consolidated financial statements. We plan to adopt these amendments on October 1, 2022 and expect to use the modified retrospective approach as currently required.
