BASIS OF PRESENTATION, RISKS AND UNCERTAINTIES, ACCOUNTING POLICIES AND RECENT ACCOUNTING DEVELOPMENTS	NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS 1. BASIS OF PRESENTATION, RISKS AND UNCERTAINTIES, ACCOUNTING POLICIES AND RECENT ACCOUNTING DEVELOPMENTS Hanover Bancorp, Inc. (the “Company”), is a New York corporation which is the holding company for Hanover Community Bank (the “Bank”). 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, 2023, its consolidated statements of income for the three and nine months ended June 30, 2023 and 2022, its consolidated statements of comprehensive income for the three and nine months ended June 30, 2023 and 2022, its consolidated statements of changes in stockholders’ equity for the three and nine months ended June 30, 2023 and 2022 and its consolidated statements of cash flows for the nine months ended June 30, 2023 and 2022. 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, 2023 are not necessarily indicative of the results of operations to be expected for the remainder of the fiscal 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, 2022. 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 The United States economy is currently experiencing a level of price inflation not experienced since the late 1970's and early 1980's. It is therefore difficult to predict the response of consumers and businesses to this level of inflation, and its impact on the economy. In addition, in order to attempt to control and reduce the level of inflation, the Federal Reserve has embarked on a series of interest rate increases along with quantitative tightening to further constrict economic conditions. It is unclear whether the Federal Reserve’s efforts will be successful, and what impact they may have on the United States’ economy. It is possible that that the combined effects of inflation and increases in market interest rates could cause the economy of the United States to enter a recession, which could negatively impact the businesses of our borrowers and their ability to repay their loans or need credit, which could negatively affect our results of operations. ​ 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 contractual life of loans 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, 2023 and September 30, 2022, the Company had loans totaling $0.1 million and $1.2 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.

The FASB amended existing guidance that requires lessees recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) A lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) A right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. The new guidance also requires enhanced disclosure about an entity’s leasing arrangements. The Company adopted Topic 842 using the transition approach of applying the new leases standard at the beginning of the period of adoption on October 1, 2022. The new guidance includes a number of optional transition-related practical expedients that must be elected as a package and applied by a reporting entity to all of its leases consistently. The Company has elected to apply the package of practical expedients to all its existing leases, which among other things, allowed the Company to carry forward the historical lease classification as operating leases in accordance with previous GAAP. The effect of adopting this standard in the Company’s Consolidated Statements of Financial Condition was a $10 million increase in operating lease assets and operating lease liabilities In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. In March 2022, the FASB issued ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The ASU made certain targeted amendments specific to troubled debt restructurings (TDRs) by creditors and vintage disclosure related to gross write-offs. Upon adoption, the Company will be required to apply the loan and refinancing and restructuring guidance to determine whether a modification results in a new loan or a continuation of an existing loan, rather than applying the recognition and measurement guidance for TDRs. The ASU also requires companies to disclose current-period gross write-offs by year of origination for financing receivables and net investment in leases within scope of Subtopic 326-20. ASU 2022-02 is effective for fiscal years beginning after December 15, 2022 for entities that have adopted ASU 2016-13, otherwise effective date is the same as ASU 2016-13. The Company will adopt ASU 2016-13 effective October 1, 2023 and will simultaneously implement ASU 2022-02. ​

EARNINGS PER SHARE	2. EARNINGS PER SHARE The two-class method is used in the calculation of basic and diluted earnings per share (“EPS”). Under the two-class method, earnings available to common shareholders for the period are allocated between common shareholders and participating securities according to dividends declared and participation rights in undistributed earnings. The restricted stock awards granted by the Company contain non-forfeitable rights to dividends and therefore are considered participating securities. The Company’s basic and diluted EPS calculations for the three and nine months ended June 30, 2023 and 2022 follows.

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, 2023 and September 30, 2022, the Company had a recorded investment in TDRs totaling $1.7 million and $2.3 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, 2023 or September 30, 2022. For the three and nine months ended June 30, 2023 and 2022, 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, 2023 and 2022, 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, 2023 and September 30, 2022, the Company’s loan portfolio by credit risk rating disaggregated by portfolio segment were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2023 ​ ​ ​ Special ​ ​ ​ ​ ​ ​ (in thousands) ​ Pass ​ Mention ​ Substandard ​ Doubtful ​ Total Real Estate: ​ ​ ​ ​ ​ Residential ​ $ 618,809 ​ $ 3,809 ​ $ 2,646 ​ $ — ​ $ 625,264 Multi-family ​ 580,338 ​ — ​ 3,499 ​ — ​ 583,837 Commercial ​ 519,268 ​ 7,177 ​ 7,015 ​ — ​ 533,460 Commercial and industrial ​ 66,157 ​ 1,078 ​ 683 ​ — ​ 67,918 Construction and land development ​ 12,660 ​ — ​ — ​ — ​ 12,660 Consumer ​ 364 ​ — ​ — ​ — ​ 364 Total ​ $ 1,797,596 ​ $ 12,064 ​ $ 13,843 ​ $ — ​ $ 1,823,503 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2022 ​ ​ ​ Special ​ ​ ​ ​ ​ ​ (in thousands) ​ Pass ​ Mention ​ Substandard ​ Doubtful ​ Total Real Estate: ​ ​ ​ ​ ​ Residential ​ $ 512,595 ​ $ 512 ​ $ 3,151 ​ $ — ​ $ 516,258 Multi-family ​ 571,128 ​ — ​ 3,933 ​ — ​ 575,061 Commercial ​ 453,321 ​ 8,085 ​ 11,578 ​ — ​ 472,984 Commercial and industrial ​ 43,314 ​ 540 ​ 2,431 ​ — ​ 46,285 Construction and land development ​ 10,499 ​ 2,408 ​ — ​ — ​ 12,907 Consumer ​ 36 ​ — ​ — ​ — ​ 36 Total ​ $ 1,590,893 ​ $ 11,545 ​ $ 21,093 ​ $ — ​ $ 1,623,531 ​

EQUITY COMPENSATION PLANS
EQUITY COMPENSATION PLANS	5. 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 265,307 shares remain available for issuance at June 30, 2023. Of the total 346,000 shares of common stock approved for issuance under the 2018 Plan, 16,159 shares remain available for issuance at June 30, 2023. 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. There were no stock options exercised during the three months ended June 30, 2023 and 10,614 stock options exercised during the nine months ended June 30, 2023. No stock options were exercised during the three and nine months ended June 30, 2022.

Compensation expense attributable to restricted stock awards was $1.4 million and $1.1 million for the nine months ended June 30, 2023 and 2022, respectively. As of June 30, 2023, there was $4.2 million of total unrealized compensation cost related to unvested restricted stock, expected to be recognized over a weighted-average term of 3.62 years. The total fair value of shares vested during the nine months ended June 30, 2023 and 2022 was $1.3 million and $824 thousand, respectively. ​ Restricted Stock Units Long Term Incentive Plan ​ Restricted stock units (“RSU”s) 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 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, 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted-Average ​ ​ Number of ​ Grant Date Fair ​ Shares Value Unvested, October 1, 2022 ​ 47,676 ​ $ 19.73 Granted — ​ — Vested — ​ — Forfeited (6,072) ​ 19.73 Unvested, June 30, 2023 41,604 ​ $ 19.73 ​ No RSUs were granted during the nine months ended June 30, 2023. Performance-based RSUs granted in 2022 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 $61 thousand and $210 thousand, respectively, for the three and nine months ended June 30, 2023. Compensation expense attributable to RSUs was $82 thousand and $139 thousand, respectively, for the three and nine months ended June 30, 2022.

REGULATORY MATTERS

REGULATORY MATTERS
REGULATORY MATTERS	6. 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 that as of June 30, 2023, 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, 2023 and September 30, 2022, the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt corrective action.

FAIR VALUE.
FAIR VALUE	7. 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, 2023 and September 30, 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2023 ​ ​ ​ ​ 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 ​ $ 211 ​ $ — ​ $ 211 ​ $ — Corporate bonds ​ 10,883 ​ — ​ 9,683 ​ 1,200 Loan servicing rights ​ ​ 4,375 ​ ​ — ​ ​ — ​ ​ 4,375 Derivatives ​ 142 ​ — ​ 142 ​ — Total ​ $ 15,611 ​ $ — ​ $ 10,036 ​ $ 5,575 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2022 ​ ​ ​ ​ 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 ​ $ 242 ​ $ — ​ $ 242 ​ $ — Corporate bonds ​ 12,043 ​ — ​ 12,043 ​ — Loan servicing rights ​ 4,353 ​ — ​ — ​ 4,353 Total ​ $ 16,638 ​ $ — ​ $ 12,285 ​ $ 4,353 ​ 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. Derivatives represent interest rate swaps for which the estimated fair values are based on valuation models using observable market data as of the measurement date resulting in a Level 2 classification. 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, 2023 was determined based on discounted expected future cash flows cash flows The fair value of loan servicing rights for SBA loans at June 30, 2023 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.

DERIVATIVES
DERIVATIVES	10. DERIVATIVES ​ Cash Flow Hedges of Interest Rate Risk As part of its asset liability management, the Company utilizes interest rate swap agreements to help manage its interest rate risk position. The notional amount of the interest rate swap does not represent the amount exchanged by the parties. The amount exchanged is determined by reference to the notional amount and the other terms of the individual interest rate swap agreements. The Company executed its first interest rate swap agreement in June 2023. Interest rate swaps with notional amounts totaling $25.0 million as of June 30, 2023 were designated as cash flow hedges of certain Brokered Certificates of Deposit. The swaps were determined to be fully effective during the periods presented and therefore no amount of ineffectiveness has been included in net income. The aggregate fair value of the swaps is recorded in other assets/(other liabilities) with changes in fair value recorded in other comprehensive income (loss). The amount included in accumulated other comprehensive income (loss) would be reclassified to current earnings should the hedges no longer be considered effective. The Company expects the hedges to remain fully effective during the remaining term of the swaps. ​ Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest income/expense as interest payments are made/received on the Company’s variable-rate assets/liabilities. During the next twelve months, the Company estimates that $0.3 million will be reclassified as a decrease in interest expense. ​ The following table presents the net gains (losses) recorded in accumulated other comprehensive income and the consolidated statements of income relating to the cash flow derivative instruments for the periods indicated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended June 30, Nine Months Ended June 30, (in thousands) 2023 2022 ​ 2023 2022 Gain recognized in other comprehensive income ​ $ 111 ​ $ — $ 111 ​ $ — ​ The following table reflects the cash flow hedges included in the consolidated statements of financial condition as of the dates indicated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2023 September 30, 2022 ​ ​ ​ Fair Fair ​ ​ Fair Fair ​ ​ Notional ​ Value ​ Value ​ Notional ​ Value ​ Value (in thousands) ​ Amount ​ Asset ​ Liability ​ Amount ​ Asset ​ Liability Included in other assets/(liabilities): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Interest rate swaps related to Brokered Certificates of Deposit $ 25,000 $ 142 $ — ​ $ — $ — $ — ​ Credit-Risk-Related Contingent Features The Company has minimum collateral posting thresholds with certain of its derivative counterparties. If the termination value of derivatives is a net liability position, the Company is required to post collateral against its obligations under the agreements. However, if the termination value of derivatives is a net asset position, the counterparty is required to post collateral to the Company. At June 30, 2023, the Company received no collateral from its counterparties under the agreements in a net asset position. As of June 30, 2023, there were no derivatives in a net liability position, and therefore the termination value was zero.

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, 2023 are not necessarily indicative of the results of operations to be expected for the remainder of the fiscal 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, 2022. 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 The United States economy is currently experiencing a level of price inflation not experienced since the late 1970's and early 1980's. It is therefore difficult to predict the response of consumers and businesses to this level of inflation, and its impact on the economy. In addition, in order to attempt to control and reduce the level of inflation, the Federal Reserve has embarked on a series of interest rate increases along with quantitative tightening to further constrict economic conditions. It is unclear whether the Federal Reserve’s efforts will be successful, and what impact they may have on the United States’ economy. It is possible that that the combined effects of inflation and increases in market interest rates could cause the economy of the United States to enter a recession, which could negatively impact the businesses of our borrowers and their ability to repay their loans or need credit, which could negatively affect our results of operations.
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 contractual life of loans 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, 2023 and September 30, 2022, the Company had loans totaling $0.1 million and $1.2 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 Pronouncements	Recent Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016 02, Leases (Topic 842). The FASB amended existing guidance that requires lessees recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) A lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) A right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. The new guidance also requires enhanced disclosure about an entity’s leasing arrangements. The Company adopted Topic 842 using the transition approach of applying the new leases standard at the beginning of the period of adoption on October 1, 2022. The new guidance includes a number of optional transition-related practical expedients that must be elected as a package and applied by a reporting entity to all of its leases consistently. The Company has elected to apply the package of practical expedients to all its existing leases, which among other things, allowed the Company to carry forward the historical lease classification as operating leases in accordance with previous GAAP. The effect of adopting this standard in the Company’s Consolidated Statements of Financial Condition was a $10 million increase in operating lease assets and operating lease liabilities In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. In March 2022, the FASB issued ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The ASU made certain targeted amendments specific to troubled debt restructurings (TDRs) by creditors and vintage disclosure related to gross write-offs. Upon adoption, the Company will be required to apply the loan and refinancing and restructuring guidance to determine whether a modification results in a new loan or a continuation of an existing loan, rather than applying the recognition and measurement guidance for TDRs. The ASU also requires companies to disclose current-period gross write-offs by year of origination for financing receivables and net investment in leases within scope of Subtopic 326-20. ASU 2022-02 is effective for fiscal years beginning after December 15, 2022 for entities that have adopted ASU 2016-13, otherwise effective date is the same as ASU 2016-13. The Company will adopt ASU 2016-13 effective October 1, 2023 and will simultaneously implement ASU 2022-02.
