Accounting Policies [Abstract]
Summary of Significant Accounting Policies	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES A summary of significant accounting and reporting policies applied in the presentation of the accompanying financial statements follows: Nature of Operations and Basis of Presentation The consolidated financial statements include the accounts of ESSA Bancorp, Inc. (the “Company”), its wholly owned subsidiary, ESSA Bank & Trust (the “Bank”), and the Bank’s wholly owned subsidiaries, ESSACOR Inc.; Pocono Investments Company; ESSA Advisory Services, LLC; Integrated Financial Corporation; and Integrated Abstract Incorporated, a wholly owned subsidiary of Integrated Financial Corporation. The primary purpose of the Company is to act as a holding company for the Bank. On November 6, 2014, the Company converted its status from a savings and loan holding company to a bank holding company. In addition, the Bank converted from a Pennsylvania-chartered savings association to a Pennsylvania-chartered savings bank. The Bank’s primary business consists of the taking of deposits and granting of loans to customers generally in Monroe, Northampton, Lehigh, Lackawanna, Luzerne, Delaware, Chester, and Montgomery counties, Pennsylvania. The Bank is subject to regulation and supervision by the Pennsylvania Department of Banking and Securities and the Federal Deposit Insurance Corporation. The investment in subsidiary on the parent company’s financial statements is carried at the parent company’s equity in the underlying net assets. ESSACOR, Inc. is a Pennsylvania corporation that has been used to purchase properties at tax sales that represent collateral for delinquent loans of the Bank and is currently inactive. Pocono Investment Company is a Delaware corporation formed as an investment company subsidiary to hold and manage certain investments, including certain intellectual property. ESSA Advisory Services, LLC is a Pennsylvania limited liability company owned 100 percent by ESSA Bank & Trust. ESSA Advisory Services, LLC is a full-service insurance benefits consulting company offering group services such as health insurance, life insurance, short-term and long-term disability, dental, vision, and 401(k) retirement planning as well as individual health products. Integrated Financial Corporation is a Pennsylvania Corporation that provided investment advisory services to the general public and is currently inactive. Integrated Abstract Incorporated is a Pennsylvania Corporation that provided title insurance services and is currently inactive. All significant intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates in the Preparation of Financial Statements The accounting principles followed by the Company and its subsidiary and the methods of applying these principles conform to U.S. generally accepted accounting principles and to general practice within the banking industry. In preparing the consolidated financial statements, the Company is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the Consolidated Balance Sheet date and related revenues and expenses for the period. Actual results could differ from those estimates. Securities The Company determines the appropriate classification of debt securities at the time of purchase and reevaluates such designation as of each balance sheet date. Securities classified as available for sale are those securities 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 maturity mix of the Company’s assets and liabilities, liquidity needs, regulatory capital considerations, and other similar factors. Securities available for sale are carried at fair value. Unrealized gains and losses are reported in other comprehensive income (loss), net of the related deferred tax effects. 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 using the interest method over the period to maturity. Declines in the fair value of 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, the Company 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; and (3) the Company’s intent to sell the security or whether it’s more likely than not that the Company would be required to sell the security before its anticipated recovery in market value. Securities classified as held-to-maturity are those that the Company has the positive intent and ability to hold until maturity. These securities are reported at amortized cost. The fair market value of the equity securities tends to fluctuate with the overall equity markets as well as the trends specific to each institution. The equity securities portfolio is reviewed in a similar manner as that of the debt securities with greater emphasis placed on the length of time the market value has been less than the carrying value and the financial sector outlook. The Company also reviews dividend payment activities, levels of non-performing assets and loan loss reserves. The starting point for the equity analysis is the length and severity of market value decline. The realized loss is recognized as impairment charges on securities on the consolidated statements of income. The previous cost basis less the OTTI recognized in earnings becomes the new cost basis of the investment. Certain equity securities that do not have a readily determinable fair value are stated at cost, adjusted for observable price changes in orderly transactions for identical or similar investments of the same issuer. These securities include restricted stock of the Federal Home Loan Bank of Pittsburgh, as well as other equity securities. Loans Receivable Loans receivable that the Company has the intent and ability to hold for the foreseeable future or until maturity or payoff are stated at their outstanding unpaid principal balances, net of an allowance for loan losses and any deferred fees and costs. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the yield (interest income) of the related loans. The Company is generally amortizing these amounts over the contractual life of the loan. The accrual of interest is generally discontinued when the contractual payment of principal or interest has become 90 days past due or the Company has serious doubts about further collectability of principal or interest, even though the loan is currently performing. A loan may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan is placed on nonaccrual status, unpaid interest credited to income is reversed. Interest received on nonaccrual loans generally is either applied against principal or reported as interest income, according to the Company’s judgment as to the collectability of principal. Generally, loans are restored to accrual status when the obligation is brought current and has performed in accordance with the contractual terms for a reasonable period of time and the ultimate collectability of the total contractual principal and interest is no longer in doubt. Loans Acquired Loans acquired including loans that have evidence of deterioration of credit quality since origination and for which it is probable, at acquisition, that the Company will be unable to collect all contractually required payments receivable, are initially recorded at fair value (as determined by the present value of expected future cash flows) with no valuation allowance. Loans are evaluated individually to determine if there is evidence of deterioration of credit quality since origination. The difference between the undiscounted cash flows expected at acquisition and the investment in the loan, or the “accretable yield,” is recognized as interest income on a level-yield method over the life of the loan. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition, or the “non-accretable difference,” are not recognized as a yield adjustment or as a loss accrual or a valuation allowance. Increases in expected cash flows subsequent to the initial investment are recognized prospectively through adjustment of the yield on the loan over its remaining estimated life. Decreases in expected cash flows are recognized immediately as impairment. Any valuation allowances on these impaired loans reflect only losses incurred after acquisition. For purchased loans acquired that are not deemed impaired at acquisition, credit discounts representing the principal losses expected over the life of the loan are a component of the initial fair value. Loans are aggregated and accounted for as a pool of loans if the loans being aggregated have common risk characteristics. Subsequent to the purchase date, the methods utilized to estimate the required allowance for credit losses for these loans is similar to originated loans; however, the Company records a provision for loan losses only when the required allowance exceeds any remaining credit discounts. The remaining differences between the purchase price and the unpaid principal balance at the date of acquisition are recorded in interest income over the life of the loans. Allowance for Loan Losses The allowance for loan losses is established through provisions for loan losses charged against income. Loans deemed to be uncollectible are charged against the allowance for loan losses, and subsequent recoveries, if any, are credited to the allowance for loan losses. The allowance for loan losses is maintained at a level by management which represents the evaluation of known and inherent risks in the loan portfolio at the Consolidated Balance Sheet date. Management’s periodic evaluation of the adequacy of the allowance is based on the Company’s past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral, composition of the loan portfolio, current economic conditions, and other relevant factors. This evaluation is inherently subjective, since it requires material estimates that may be susceptible to significant change, including the amounts and timing of future cash flows expected to be received on impaired loans. The allowance for loan losses consists of specific and general components. The specific component relates to loans that are classified as impaired. For such loans an allowance for loan losses 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. The general component covers nonclassified loans and is based on historical loss experience adjusted for qualitative factors. All loans are considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement and all loan types are considered impaired if the loan is restructured in a troubled debt restructuring. 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 the 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. Impairment is measured on a loan-by-loan basis for commercial and construction loans by the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral-dependent. Large groups of smaller-balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer and residential mortgage loans for impairment disclosures unless such loans are part of a larger relationship that is impaired or classified as a troubled debt restructuring or is more than 180 days past due. A loan is considered to be a troubled debt restructuring (“TDR”) loan when the Company grants a concession to the borrower because of the borrower’s financial condition that it would not otherwise consider. Such concessions include the reduction of interest rates, forgiveness of principal or interest, or other modifications of interest rates that are less than the current market rate for new obligations with similar risk. TDR loans that are in compliance with their modified terms and that yield a market rate may be removed from the TDR status after one year of performance. Regulatory Stock Regulatory stock consists of Federal Home Loan Bank (“FHLB”) of Pittsburgh stock and Atlantic Community Bankers Bank stock. Regulatory stock is carried at cost. The Company is a member of the Federal Home Loan Bank System and holds stock in the Federal Home Loan Bank of Pittsburgh. As a member, the Company maintains an investment in the capital stock of the FHLB of Pittsburgh in an amount not less than 10 basis points of the outstanding member asset value plus 4.0 percent of its outstanding FHLB borrowings, as calculated throughout the year. The equity security is accounted for at cost and classified separately on the Consolidated Balance Sheet. The stock is bought from and sold to the FHLB based upon its $100 par value. The stock does not have a readily determinable fair value and as such is classified as restricted stock, carried at cost and evaluated by management. The stock’s value is determined by the ultimate recoverability of the par value rather than by recognizing temporary declines. The determination of whether the par value will ultimately be recovered is influenced by criteria such as the following: (a) The significance of the decline in net assets of the FHLB as compared to the capital stock amount and the length of time this situation has persisted; (b) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance; (c) the impact of legislative and regulatory changes on the customer base of the FHLB; and (d) the liquidity position of the FHLB. With consideration given to these factors, management concluded that the stock was not impaired at September 30, 2022. Loan Servicing Servicing assets are recognized as separate assets when rights are acquired through purchase or through sale of financial assets. Capitalized servicing rights are reported in other assets and are amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets. Servicing assets are evaluated for impairment based upon a third-party appraisal. Fair value is determined using prices for similar assets with similar characteristics, when available, or based upon discounted cash flows using market-based assumptions. Impairment is recognized through a valuation allowance to the extent that fair value is less than the capitalized amount. The Company’s loan servicing assets a t September 30, 2022 and 2021 , were not impaired. Total servicing assets included in other assets as of September 30, 2022 and 2021 , were $ 788,000 and $ , respectively . Premises and Equipment Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the useful lives of the related assets, which range from 10 to 40 years for buildings, land improvements, and leasehold improvements and three to seven years for furniture, fixtures, and equipment. Expenditures for maintenance and repairs are charged to operations as incurred. Costs of major additions and improvements are capitalized. Derivative Instruments and Hedging Activities The Company records all derivatives on the Consolidated Balance Sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. In accordance with the FASB’s fair value measurement guidance, the Company has elected to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio. Bank-Owned Life Insurance (“BOLI”) The Company owns insurance on the lives of a certain group of key employees. The policies were purchased to help offset the increase in the costs of various fringe benefit plans, including healthcare. The cash surrender value of these policies is included as an asset on the Consolidated Balance Sheet, and any increase in cash surrender value is recorded as noninterest income on the Consolidated Statement of Income. In the event of the death of an insured individual under these policies, the Company would receive a death benefit which would be recorded as noninterest income. Foreclosed Real Estate Real estate owned acquired in settlement of foreclosed loans is carried at fair value minus estimated costs to sell. At acquisition of real estate acquired in settlement of foreclosed loans, the excess of the remaining loan balance over the asset’s estimated fair value less cost to sell is charged off against the allowance for loan losses. Subsequent declines in the asset’s value are recognized as noninterest expense in the Consolidated Statement of Income. Operating expenses of such properties, net of related income, are expensed in the period incurred. Goodwill and Intangible Assets Goodwill is not amortized, but it is tested at least annually for impairment in the fourth quarter, or more frequently if indicators of impairment are present. If the estimated current fair value of a reporting unit exceeds its carrying value, no additional testing is required and an impairment loss is not recorded. The Company uses market capitalization and multiples of tangible book value methods to determine the estimated current fair value of its reporting unit. Based on this analysis, no impairment was recorded in 2022 or 2021. The other intangible assets are assigned useful lives, which are amortized on an accelerated basis over their weighted-average lives. The Company periodically reviews intangible assets for impairment as events or changes in circumstances indicate that the carrying amount of such asset may not be recoverable. Based on these reviews, no impairment was recorded in 2022 and 2021. The following tables provide information for the carrying amount of goodwill and intangible assets (in thousands): Goodwill 2022 2021 Balance at beginning of year $ 13,801 $ 13,801 Goodwill acquired - - Balance at end of year $ 13,801 $ 13,801 Intangible assets 2022 2021 Balance at beginning of year $ 520 $ 791 Intangible assets acquired - - Amortization (239 ) (271 ) Balance at end of year $ 281 $ 520 Amortizable intangible assets were composed of the following (in thousands): September 30, 2022 2021 Gross Amount Accumulated Amortization (dollars in thousands) Core deposit intangible $ 4,787 $ 4,506 $ 4,267 2022 2021 Aggregate amortization expense: As of the years ended September 30 $ 239 $ 271 Estimated future amortization expense (in thousands): 2023 $ 190 2024 91 $ 281 Employee Benefit Plans The Bank maintains a noncontributory, defined benefit pension plan for all employees who have met age and length of service requirements. The Bank also maintains a defined contribution Section 401(k) plan covering eligible employees. The Company created an ESOP for the benefit of employees who meet certain eligibility requirements. The Company makes cash contributions to the ESOP on an annual basis. The Company maintains an equity incentive plan to provide for issuance or granting of shares of common stock for stock options or restricted stock. The Company has recorded stock-based employee compensation cost using the fair value method as allowed under generally accepted accounting principles. Management estimated the fair values of all option grants using the Black-Scholes option-pricing model. Management estimated the expected life of the options using the simplified method as allowed under generally accepted accounting principles. The risk-free rate was determined utilizing the treasury yield for the expected life of the option contract. Advertising Costs The Company expenses all advertising expenditures 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 of 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 their maturity. Income Taxes Deferred tax assets and liabilities are reflected based on the differences between the financial statement and the income tax basis of assets and liabilities using the enacted marginal tax rates. Deferred income tax expense and benefit are based on the changes in the deferred tax assets or liabilities from period to period. Deferred tax assets and liabilities are reflected at currently enacted income tax rates applicable to the period in which such items are expected to be realized or settled. As changes in tax rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. The Company files a consolidated federal income tax return and individual state income tax returns. The Company prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Benefits from tax positions should be recognized in the financial statements only when it is more likely than not that the tax position will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should be derecognized in the first subsequent financial reporting period in which that threshold is no longer met. Cash and Cash Equivalents The Company has defined cash and cash equivalents as cash and due from banks and interest-bearing deposits with other institutions with original maturities of less than 90 days. Earnings Per Share The Company provides dual presentation of basic and diluted earnings per share. Basic earnings per share are calculated utilizing net income as reported as the numerator and average shares outstanding as the denominator. The computation of diluted earnings per share differs in that the dilutive effects of any options are adjusted for in the denominator. Comprehensive Income (Loss) The Company is required to present comprehensive income (loss) and its components in a full set of general-purpose financial statements for all periods presented. Other comprehensive income (loss) is composed of net unrealized holding gains or losses on its available-for-sale investment and mortgage-backed securities portfolio and derivative instruments, and changes in unrecognized pension cost. Fair Value Measurements The Company groups assets and liabilities carried at fair value in three levels, based on the markets in which the assets are traded and the reliability of the assumptions used to determine fair value. These levels are: • Level I – Valuation is based upon quoted prices for identical instruments traded in active markets. • Level II – Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. • Level III – Valuation is generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect the Company’s own estimates of assumptions that market participants would use in pricing the asset. The Company determines fair value based on 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. It is our policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements, in accordance with the fair value hierarchy in generally accepted accounting principles. Fair value measurements for most of the Company’s assets are obtained from independent pricing services that we have engaged for this purpose. When available, the Company, or the Company’s independent pricing service, use quoted market prices to measure fair value. If market prices are not available, fair value measurement is based upon models that incorporate available trade, bid, and other market information. Subsequently, all of the Company’s financial instruments use either of the foregoing methodologies to determine fair value adjustments recorded to our financial statements. In certain cases, however, when market observable inputs for model-based valuation techniques may not be readily available, we are required to make judgments about assumptions market participants would use in estimating the fair value of financial instruments. The degree of management judgment involved in determining the fair value of a financial instrument is dependent upon the availability of quoted market prices or observable market parameters. For financial instruments that trade actively and have quoted market prices or observable market parameters, there is minimal subjectivity involved in measuring fair value. When observable market prices and parameters are not fully available, management judgment is necessary to estimate fair value. In addition, changes in the market conditions may reduce the availability of quoted prices or observable data. When market data is not available, we use valuation techniques requiring more management judgment to estimate the appropriate fair value measurement. Therefore, the results cannot be determined with precision and may not be realized in an actual sale or immediate settlement of the asset. Additionally, there may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, that could significantly affect the results of current or future valuations. Reclassification of Comparative Amounts Certain items previously reported have been reclassified to conform to the current year’s reporting format. Such reclassifications did not affect consolidated net income or consolidated stockholders’ equity. Adoption of New Standards ASC 715 In August 2018, the FASB issued ASU 2018-14, Compensation – Retirement Benefits (Topic 715-20). This Update amends to add, remove and clarify disclosure requirements related to defined benefit pension and other postretirement plans. The Update eliminates the requirement to disclose the amounts in accumulated other comprehensive income expected to be recognized as part of net periodic benefit cost over the next year. The Update also removes the disclosure requirements for the effects of a one-percentage-point change on the assumed health care costs and the effect of this change in rates on service cost, interest cost and the benefit obligation for postretirement health care benefits. This Update is effective for public business entities for fiscal years ending after December 15, 2020, and must be applied on a retrospective basis. The adoption of ASU 2018-14 did not have a significant impact on the Company’s financial statements. In January 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting In October 2020, the FASB issued ASU 2020-08, Codification Improvements to Subtopic 310-20, Receivables – Nonrefundable Fees and Other Costs, In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848) 2020 effectiveness for periods after December 31, 2022, except for certain hedging relationships existing as of December 31, 2022, that apply certain optional expedients in which the accounting effects are recorded through the end of the hedging relationship. The adoption of ASU 2021-01 did no t have a significant impact on the Company’s financial statements. Recent Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments Financial Instruments ‒ Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842) In May 2019, the FASB issued ASU 2019-05, Financial Instruments – Credit Losses (Topic 326) In November 2019, the FASB issued ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments – Credit Losses In March 2020, the FASB issued ASU 2020-03 , Codification Improvements to Financial Instruments. Financial Instruments related to ASU 2016-13 for entities that have not yet adopted that guidance are effective upon adoption of the amendments in ASU 2016-13. Early adoption is not permitted before an entity’s adoption of ASU 2016-13. Amendments related to ASU 2016-13 for entities that have adopted that guidance are effective for fiscal years beginning after December 15, 2019, including interim periods within those years. Other amendments are effective upon issuance of this ASU. This Update is not expected to have a significant impact on the Company’s financial statements.

The Company reviews its position quarterly and has asserted that at September 30, 2022 and 2021, the declines outlined in the above table represent temporary declines and the Company would not be required to sell the security before its anticipated recovery in market value. The Company has concluded that any impairment of its investment securities portfolio at September 30, 2022 and 2021, is not other than temporary but is the result of interest rate changes that are not expected to result in the noncollection of principal and interest during the period.

Loans Receivable	4. LOANS RECEIVABLE Loans receivable consist of the following (in thousands): 2022 2021 Real estate loans: Residential $ 623,375 $ 580,313 Construction 25,024 14,013 Commercial 678,841 591,117 Commercial 38,158 63,500 Obligations of states and political subdivisions 40,416 56,164 Home equity loans and lines of credit 43,170 38,426 Auto loans 3,611 13,852 Other 1,716 1,581 1,454,311 1,358,966 Less allowance for loan losses 18,528 18,113 Net loans $ 1,435,783 $ 1,340,853 During 2020 and 2021 the Company participated in the Paycheck Protection Program (“PPP”), administered directly by the U.S. SBA. The PPP provides loans to small businesses who were affected by economic conditions as a result of COVID-19 to provide cash-flow assistance to employers who maintain their payroll (including healthcare and certain related expenses), mortgage interest, rent, leases, utilities and interest on existing debt during the COVID-19 emergency. As of September 30, 2022, the Company had outstanding principal balances of $702,000 compared to $22.6 million on September 30, 2021. The PPP loans are fully guaranteed by the SBA and may be eligible for forgiveness by the SBA to the extent that the proceeds are used to cover eligible payroll costs, interest costs, rent, and utility costs over a period of up to 24 weeks after the loan is made as long as certain conditions are met regarding employee retention and compensation levels. PPP loans deemed eligible for forgiveness by the SBA will be repaid by the SBA to the Company. PPP loans are included in the Commercial loan category. In accordance with the SBA terms and conditions on the outstanding PPP loans of $702,000 as of September 30, 2022, the Company has approximately $30,000 in unamortized fees associated with the processing of these loans. Upon funding of the loan, these fees were deferred and will be amortized over the life of the loan as an adjustment to yield in accordance with FASB ASC 310-20-25-2. Included in the September 30, 2022 balances are loans acquired from First Star Bank in 2012, Franklin Security Bank in 2014 and Eagle National Bank in 2015. There has been $184,000 in allowance for loan losses recorded for acquired loans with or without specific evidence of deterioration in credit quality as of September 30, 2022. There has been $182,000 in allowance for loan losses recorded for acquired loans with or without specific evidence of deterioration in credit quality as of September 30, 2021. In addition, no allowance for loan losses has been reversed. Loans serviced by the Company for others amounted to $200.2 million and $193.9 million at September 30, 2022 and 2021, respectively. The Company began selling current production residential real estate loans to the FHLB in February 2020. The Company’s primary business activity is with customers located in counties where its branch offices are located and to a lesser extent, the contiguous counties in the Commonwealth of Pennsylvania. Commercial, residential, and consumer loans are granted. The Company also funds commercial and residential loans originated outside its immediate trade area provided such loans meet the Company’s credit policy guidelines. Although the Company has a diversified loan portfolio at September 30, 2022 and 2021, loans outstanding to individuals and businesses are dependent upon the local economic conditions in its immediate trade area. The following tables show the amount of loans in each category that was individually and collectively evaluated for impairment at the dates indicated (in thousands): Total Loans Individually Evaluated for Impairment Loans Acquired with Deteriorated Credit Quality Collectively Evaluated for Impairment September 30, 2022 Real estate loans: Residential $ 623,375 $ 1,342 $ - $ 622,033 Construction 25,024 - - 25,024 Commercial 678,841 12,165 - 666,676 Commercial 38,158 937 - 37,221 Obligations of states and political subdivisions 40,416 - - 40,416 Home equity loans and lines of credit 43,170 36 - 43,134 Auto Loans 3,611 16 - 3,595 Other 1,716 6 - 1,710 Total $ 1,454,311 $ 14,502 $ - $ 1,439,809 Total Loans Individually Evaluated for Loans Acquired with Deteriorated Credit Quality Collectively Evaluated for Impairment September 30, 2021 Real estate loans: Residential $ 580,313 $ 2,646 $ - $ 577,667 Construction 14,013 - - 14,013 Commercial 591,117 11,166 877 579,074 Commercial 63,500 1,355 - 62,145 Obligations of states and political subdivisions 56,164 - - 56,164 Home equity loans and lines of credit 38,426 336 - 38,090 Auto Loans 13,852 39 - 13,813 Other 1,581 8 - 1,573 Total $ 1,358,966 $ 15,550 $ 877 $ 1,342,539 The Company maintains a loan review system, which allows for a periodic review of our loan portfolio and the early identification of potential impaired loans. Such system takes into consideration, among other things, delinquency status, size of loans, type and market value of collateral, and financial condition of the borrowers. Specific loan loss allowances are established for identified losses based on a review of such information. A loan evaluated for impairment is considered to be impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. All loans identified as impaired are evaluated independently. The Company does not aggregate such loans for evaluation purposes. Impairment is measured on a loan-by-loan basis for commercial and construction loans by the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral-dependent. The following tables include the recorded investment and unpaid principal balances for impaired loans with the associated allowance amount, if applicable, excluding purchased impaired credit loans. Also presented are the average recorded investments in the impaired loans and the related amount of interest recognized during the time within the period that the impaired loans were impaired (in thousands).

The first six categories are considered not criticized and are aggregated as Pass-rated. The criticized rating categories utilized by management generally follow bank regulatory definitions. The Special Mention category includes assets that are fundamentally sound yet, exhibit potentially unacceptable credit risk or deteriorating trends or characteristics which if left uncorrected, may result in deterioration of the repayment prospects for the asset or in the Company’s credit position at some future date. Loans in the Substandard category have well-defined weaknesses that jeopardize the liquidation of the debt and have a distinct possibility that some loss will be sustained if the weaknesses are not corrected. All loans greater than 90 days past due are considered Substandard. Loans in the Doubtful category have all the weaknesses inherent in one classified Substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loans in the Loss category are considered uncollectible and of little value that their continuance as bankable assets is not warranted. To help ensure that risk ratings are accurate and reflect the present and future capacity of borrowers to repay a loan as agreed, the Company has a structured loan rating process with several layers of internal and external oversight. Generally, consumer and residential mortgage loans are included in the Pass categories unless a specific action, such as bankruptcy, repossession, or death, occurs to raise awareness of a possible credit event. The Company’s Commercial Loan Officers are responsible for the timely and accurate risk rating of the loans in their portfolios at origination and on an ongoing basis. The Company’s credit management team performs an annual review of all commercial relationships $2,000,000 or greater. Confirmation of the appropriate risk grade is included in the review on an ongoing basis. The Company engages an external consultant to conduct loan reviews on at least a semiannual basis. Generally, the external consultant reviews commercial relationships greater than $ 1,000,000 and/or all criticized relationships equal to or greater than $ 500,000 . Detailed reviews, including plans for resolution, are performed on loans classified as Substandard on a quarterly basis. Loans in the Special Mention and Substandard categories that are evaluated for impairment are given separate consideration in the determination of the allowance. The following tables present the classes of the loan portfolio summarized by the aggregate Pass and the criticized categories of Special Mention, Substandard, and Doubtful within the internal risk rating system as of September 30, 2022 and 2021 (in thousands): Pass Special Mention Substandard Doubtful Total September 30, 2022 Commercial real estate loans $ 659,104 $ 6,060 $ 13,677 $ - $ 678,841 Commercial 35,322 1,690 1,146 - 38,158 Obligations of states and political subdivisions 40,416 - - - 40,416 Total $ 734,842 $ 7,750 $ 14,823 $ - $ 757,415 Pass Special Mention Substandard Doubtful Total September 30, 2021 Commercial real estate loans $ 549,360 $ 20,184 $ 21,573 $ - $ 591,117 Commercial 61,657 141 1,702 - 63,500 Obligations of states and political subdivisions 56,164 - - - 56,164 Total $ 667,181 $ 20,325 $ 23,275 $ - $ 710,781 All other loans are underwritten and structured using standardized criteria and characteristics, primarily payment performance, and are normally risk rated and monitored collectively on a monthly basis. These are typically loans to individuals in the consumer categories and are delineated as either performing or nonperforming. For residential real estate loans, construction real estate loans, home equity loans and lines of credit, auto loans, and other loans, the Company evaluates credit quality based on the performance of the individual credits. The following tables present the recorded investment in the loan classes based on payment activity as of September 30, 2022 and 2021 (in thousands): Performing Nonperforming Total September 30, 2022 Real estate loans: Residential $ 621,781 $ 1,594 $ 623,375 Construction 25,024 - 25,024 Home equity loans and lines of credit 42,832 338 43,170 Auto loans 3,590 21 3,611 Other 1,710 6 1,716 Total $ 694,937 $ 1,959 $ 696,896 Performing Nonperforming Total September 30, 2021 Real estate loans: Residential $ 577,448 $ 2,865 $ 580,313 Construction 14,013 - 14,013 Home equity loans and lines of credit 37,963 463 38,426 Auto loans 13,809 43 13,852 Other 1,568 14 1,582 Total $ 644,801 $ 3,385 $ 648,186 The Company further monitors the performance and credit quality of the loan portfolio by analyzing the age of the portfolio as determined by the length of time a recorded payment is past due.

The allowance for loan losses (“ALL”) is maintained at a level necessary to absorb loan losses that are both probable and reasonably estimable. Management, in determining the allowance for loan losses, considers the losses inherent in its loan portfolio and changes in the nature and volume of loan activities, along with the general economic and real estate market conditions. The allowance for loan losses consists of three elements: (1) an allocated allowance, which comprises allowances established on specific loans and class allowances based on historical loss experience and current trends, (2) an allocated allowance based on general economic conditions and other risk factors in our markets and portfolios, and (3) an unallocated allowance not to exceed 10% of total reserves which acts as a contingency against unforeseen future events which may negatively impact the Company’s loan portfolio. We maintain a loan review system, which allows for a periodic review of our loan portfolio and the early identification of potential impaired loans. Such system takes into consideration, among other things, delinquency status, size of loans, type and market value of collateral, and financial condition of the borrowers. General loan loss allowances are based upon a combination of factors including, but not limited to, actual loan loss experience, composition of the loan portfolio, current economic conditions, management’s judgment and losses which are probable and reasonably estimable. The allowance is increased through provisions charged against current earnings and recoveries of previously charged-off loans. Loans that are determined to be uncollectible are charged against the allowance. While management uses available information to recognize probable and reasonably estimable loan losses, future loss provisions may be necessary, based on changing economic conditions. Payments received on impaired loans generally are either applied against principal or reported as interest income, according to management’s judgment as to the collectability of principal. The allowance for loan losses as of September 30, 2022 , is maintained at a level that represents management’s best estimate of losses inherent in the loan portfolio, and such losses were both probable and reasonably estimable. In addition, the FDIC and the Pennsylvania Department of Banking, as an integral part of their examination process, have periodically reviewed the Company’s allowance for loan losses. The banking regulators may require that the Company recognize additions to the ALL based on their analysis and review of information available to it at the time of their examination. Management reviews the loan portfolio on a quarterly basis using a defined, consistently applied process in order to make appropriate and timely adjustments to the ALL. When information confirms all or part of specific loans to be uncollectible, these amounts are promptly charged-off against the ALL. The following table summarizes the primary segments of the ALL, segregated into the amount required for loans individually evaluated for impairment and the amount required for loans collectively evaluated for impairment as of September 30, 2022 and 2021 (in thousands): Real Estate Loans Obligations of States and Political Home Loans and Lines of Residential Construction Commercial Commercial Subdivisions Credit Auto Other Unallocated Total ALL balance at September 30, 2020 $ 4,301 $ 127 $ 7,209 $ 874 $ 555 $ 337 $ 780 $ 25 $ 1,192 $ 15,400 Charge-offs (83 ) - (76 ) (209 ) - (9 ) (274 ) (1 ) - (652 ) Recoveries 311 - 99 - - 9 246 - - 665 Provision (415 ) 60 3,238 376 (162 ) (19 ) (520 ) (3 ) 145 2,700 ALL balance at September 30, 2021 $ 4,114 $ 187 $ 10,470 $ 1,041 $ 393 $ 318 $ 232 $ 21 $ 1,337 $ 18,113 Individually evaluated for impairment $ 17 $ - $ 14 $ 397 $ - $ - $ - $ - $ - $ 428 Collectively evaluated for impairment 4,097 187 10,456 644 393 318 232 21 1,337 17,685 ALL balance at September 30, 2021 $ 4,114 $ 187 $ 10,470 $ 1,041 $ 393 $ 318 $ 232 $ 21 $ 1,337 $ 18,113 ALL balance at September 30, 2021 $ 4,114 $ 187 $ 10,470 $ 1,041 $ 393 $ 318 $ 232 $ 21 $ 1,337 $ 18,113 Charge-offs (19 ) - (23 ) - - (6 ) (40 ) (22 ) - (110 ) Recoveries 382 - 35 - - 9 99 - - 525 Provision 645 132 272 (343 ) (110 ) 40 (269 ) 23 (390 ) - ALL balance at September 30, 2022 $ 5,122 $ 319 $ 10,754 $ 698 $ 283 $ 361 $ 22 $ 22 $ 947 $ 18,528 Individually evaluated for impairment $ 12 $ - $ 301 $ 38 $ - $ - $ - $ - $ - $ 351 Collectively evaluated for impairment 5,110 319 10,453 660 283 361 22 22 947 18,177 ALL balance at September 30, 2022 $ 5,122 $ 319 $ 10,754 $ 698 $ 283 $ 361 $ 22 $ 22 $ 947 $ 18,528 The allowance for loan losses is based on estimates, and actual losses will vary from current estimates. Management believes that the granularity of the homogeneous pools and the related historical loss ratios and other qualitative factors, as well as the consistency in the application of assumptions, result in an ALL that is representative of the risk found in the components of the portfolio at any given date. During the year ended September 30, 2022 the Company recorded provision expense for the residential real estate loans, construction real estate loans, commercial real estate loans, home equity loans and lines of credit and other loans segments due to either increased loan balances, changes in the loan mix within the pool, and/or charge-off activity in those segments. Credit provisions were recorded for loan loss for the commercial loans, obligations of states and political subdivisions, and auto loans segments due to either decreased loan balances, improved asset quality, changes in the loan mix within the pool, and/or decreased charge-off activity in those segments. During the year ended September 30, 2022, the allowance for loan loss for residential real estate loans increased $1.0 million due primarily to an increase in residential real estate loans of $43.1 million. During the year ended September 30, 2021 the Company recorded provision for loan losses for the construction loan, commercial real estate and commercial loan segments, due to either increased loan balances, changes in the loan mix within the pool, and/or charge-off activity in those segments. Credit provisions were recorded for the residential real estate, obligations of states and political subdivisions, home equity loans and lines of credit, other segments and auto loan segments due to either decreased loan balances, changes in the loan mix within the pool, and/or charge-off activity in those segments. The following is a summary of troubled debt restructurings granted during the periods indicated (dollars in thousands).

One new troubled debt restructuring granted for the year ended September 30, 2022 totaled $39,000 and was granted interest rate and interest capitalization concessions. Of the eight new troubled debt restructurings granted for the year ended September 30, 2021, six loans totaling $2.4 million were granted terms concessions and two loans totaling $6.8 million were granted terms and rate concessions. For the years ended September 30, 2022 and 2021 there was no loan modifications classified as troubled debt restructurings that subsequently defaulted within one year of modification As of September 30, 2022, the Company has initiated formal foreclosure proceedings on $748,000 of consumer residential mortgages which have not yet been transferred into foreclosed assets. COVID-19 Loan Forbearance Programs Section 4013 of the CARES Act provides that banks may elect not to categorize a loan modification as a TDR if the loan modification is (1) related to COVID-19; (2) executed on a loan that was not more than 30 days past due as of December 31, 2019; and (3) executed between March 1, 2020, and the earlier of (A) 60 days after the date on which the national emergency concerning the novel coronavirus disease (COVID–19) outbreak declared by the President on March 13, 2020, under the National Emergencies Act terminates, or (B) December 31, 2020. On December 27, 2020, the president signed into law the Consolidated Appropriations Act, 2021, which amended CARES Act Section 4013. The amendment extends the applicable period for which a financial institution is able to (a) suspend the requirements under United States generally accepted accounting principles for loan modifications related to the coronavirus disease (COVID-19) pandemic that would otherwise be categorized as a troubled debt restructuring and (b) any determination of a loan modified as a result of the effects of the COVID-19 pandemic as being a TDR, including impairment for accounting purposes. The amended end date for the relief related to a financial institution electing to suspend TDR and loan impairment accounting for qualifying modifications was extended from the earlier of December 31, 2020, or 60 days after the national emergency concerning COVID-19 declared by the president terminates to the earlier of January 1, 2022, or 60 days after the national emergency concerning COVID-19 declared by the president terminates. On April 7, 2020, federal banking regulators issued a revised interagency statement that included guidance on their approach for the accounting of loan modifications in light of the economic impact of the COVID-19 pandemic. The guidance interprets current accounting standards and indicates that a lender can conclude that a borrower is not experiencing financial difficulty if short-term modifications are made in response to COVID-19, such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant related to the loans in which the borrower is less than 30 days past due on its contractual payments at the time a modification program is implemented. According to the Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus (Revised) issued by the federal bank regulatory agencies on April 7, 2020, short-term loan modifications not otherwise eligible under Section 4013 that are made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not TDRs. This includes short-term (e.g., six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant. At September 30, 2022, one of our customers had remained on loan payment deferrals or payments of interest only on loans totaling $4.5 million. In accordance with Section 4013 of the CARES Act and the interagency guidance issued on April 7, 2020, this deferral is not considered a troubled debt restructuring.

Benefits from tax positions should be recognized in the financial statements only when it is more likely than not that the tax position will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should be derecognized in the first subsequent financial reporting period in which that threshold is no longer met. There is currently no liability for uncertain tax positions and no known unrecognized tax benefits. The Company recognizes, when applicable, interest and penalties related to unrecognized tax benefits in the provision for income taxes in the Consolidated Statement of Income. The Company’s federal and state income tax returns for taxable years through 2018 have been closed for purposes of examination by the Internal Revenue Service and the Pennsylvania Department of Revenue. The reconciliation of the federal statutory rate and the Company’s effective income tax rate is as follows (dollars in thousands): 2022 2021 Amount % of Pretax Income Amount % of Pretax Income Provision at statutory rate $ 5,251 21.0 % $ 4,178 21.0 % Income from bank-owned life insurance (159 ) (0.6 ) (179 ) (0.9 ) Tax-exempt income (292 ) (1.2 ) (404 ) (2.0 ) Low-income housing credits (45 ) (0.2 ) (187 ) (0.9 ) Other, net 179 0.7 65 0.3 Actual tax expense and effective rate $ 4,934 19.7 % $ 3,473 17.5 % The Bank is subject to the Pennsylvania Mutual Thrift Institutions Tax that is calculated at 11.5 percent of earnings based on U.S. generally accepted accounting principles with certain adjustments.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	10. COMMITMENTS AND CONTINGENT LIABILITIES In the normal course of business, management makes various commitments that are not reflected in the consolidated financial statements. These commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the Consolidated Balance Sheet. The Company’s exposure to credit loss in the event of nonperformance by the other parties to the financial instruments is represented by the contractual amounts as disclosed. Losses, if any, are charged to the allowance for loan losses. The Company minimizes its exposure to credit loss under these commitments by subjecting them to credit approval and review procedures and collateral requirements, as deemed necessary, in compliance with lending policy guidelines. The off-balance sheet commitments consist of the following (in thousands): 2022 2021 Commitments to extend credit $ 292,563 $ 254,413 Standby letters of credit 14,490 17,887 Unfunded lines of credit 124,656 119,111 The commitments outstanding at September 30, 2022, contractually mature in less than one year. The instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the Consolidated Balance Sheet. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The amount of collateral obtained, as deemed necessary, is based upon management’s credit evaluation in compliance with the lending policy guidelines. Since many of the credit line commitments are expected to expire without being fully drawn upon, the total contractual amounts do not necessarily represent future funding requirements. Standby letters of credit and financial guarantees represent conditional commitments issued to guarantee performance of a customer to a third party. The coverage period for these instruments is typically a one-year The Company is required to maintain a reserve balance with certain third party providers. At September 30, 2022 the reserve balance was $1.2 million. Legal Proceedings The Company and its subsidiaries are subject to various legal actions arising in the normal course of business. In the opinion of Management, the resolution of these legal actions is not expected to have a material adverse effect on the Company’s results of operations. The Bank was named as a defendant in an action commenced on December 8, 2016 by one plaintiff who sought to pursue this action as a class action on behalf of the entire class of people similarly situated. The plaintiff alleges that a bank previously acquired by ESSA Bancorp received unearned fees and kickbacks in the process of making loans, in violation of the Real Estate Settlement Procedures Act. In an order dated January 29, 2018, the district court granted the Bank’s motion to dismiss the case. The plaintiff appealed the court’s ruling. In an opinion and order dated April 26, 2019, the appellate court reversed the district court’s order dismissing the plaintiff’s case against the Bank and remanded the case back to the district court in order to continue the litigation. The litigation is now proceeding before the district court. On December 9, 2019, the court permitted an amendment to the complaint to add two new plaintiffs to the case asserting similar claims. On May 21, 2020, the court granted the plaintiffs’ motion for class certification. In an order dated November 24, 2020, the court referred the case to a Magistrate Judge to assist in mediation efforts. The case was stayed while the parties explored the potential for a negotiated resolution. The parties engaged in mediation but did not resolve the matter. The parties are now in the discovery process. The Bank will continue to defend against plaintiffs’ allegations. To the extent that this matter could result in exposure to the Bank, the amount of such exposure is not currently estimable. On May 29, 2020, the Bank was named as a defendant in a second action commenced by three plaintiffs who also seek to pursue this action as a class action on behalf of the entire class of people similarly situated. The plaintiffs allege that a bank previously acquired by ESSA Bancorp received unearned fees and kickbacks from a different title company than the one involved in the previously discussed litigation in the process of making loans. The original complaint alleged violations of the Real Estate Settlement Procedures Act, the Sherman Act, and the Racketeer Influenced and Corrupt Organizations Act (“RICO”). The plaintiffs filed an Amended Complaint on September 30, 2020 that dropped the RICO claim, but they are continuing to pursue the Real Estate Settlement Procedures Act and Sherman Act claims. The Bank moved to dismiss the Sherman Act claim on October 14, 2020, and that motion was denied on April 2, 2021. The parties are now in the discovery process. The Bank will continue to defend against plaintiffs’ allegations. To the extent that this matter could result in exposure to the Bank, the amount of such exposure is not currently estimable.

Leases [Abstract]
Leases	11. 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. The Company accounts for all its leases in accordance with Topic 842. For the Company, Topic 842 primarily affects the accounting treatment for operating lease agreements in which the Company is the lessee. Lessee Accounting Substantially all of the leases in which the Company is the lessee are comprised of real estate property for branches, ATM locations, and office space with terms extending through 2044. All of our leases are classified as operating leases on the Company’s Consolidated Balance Sheet for both periods. The following table presents the Consolidated Balance Sheet classification of the Company’s right-of-use assets and lease liabilities. The Company elected not to include short-term leases (i.e., leases with initial terms of twelve months or less), or equipment leases (deemed immaterial) on the Consolidated Balance sheet. (in thousands) September 30, 2022 Lease Right-of-Use Assets Classification Operating lease right-of-use assets Other assets $ 6,075 Total Lease Right-Of-Use Assets $ 6,075 (in thousands) September 30, 2022 Lease Liabilities Classification Operating lease liabilities Other liabilities $ 6,275 Total Lease Liabilities $ 6,275 (in thousands) September 30, 2021 Lease Right-of-Use Assets Classification Operating lease right-of-use assets Other assets $ 6,222 Total Lease Right-Of-Use Assets $ 6,222 (in thousands) September 30, 2021 Lease Liabilities Classification Operating lease liabilities Other liabilities $ 6,370 Total Lease Liabilities $ 6,370 The calculated amount of the ROU assets and lease liabilities in the table above are impacted by the length of the lease term and the discount rate used to present value the minimum lease payments. The Company’s lease agreements often include one or more options to renew at the Company’s discretion. If at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the ROU asset and lease liability. Regarding the discount rate, Topic 842 requires the use of the rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term. September 30, 2022 Weighted average remaining lease term Operating leases 12.2 Weighted average discount rate Operating leases 2.38 % September 30, 2021 Weighted average remaining lease term Operating leases 13.3 years Weighted average discount rate Operating leases 2.44 % The following table represents lease costs and other lease information. As the Company elected, for all classes of underlying assets, not to separate lease and non-lease components and instead to account for them as a single lease component, the variable lease cost primarily represents variable payments such as common area maintenance and utilities.

Postemployment Benefits [Abstract]
Employee Benefits	12. EMPLOYEE BENEFITS Employee Stock Ownership Plan (“ESOP”) The Company created an ESOP for the benefit of employees who meet the eligibility requirements, which include having completed one year of service with the Company or its subsidiary and attained age 21. The ESOP trust acquired 1,358,472 shares of the Company’s stock in 2007 from proceeds from a loan with the Company. The Company makes cash contributions to the ESOP on an annual basis sufficient to enable the ESOP to make the required loan payments. Cash dividends paid on allocated shares are distributed to participants and cash dividends paid on unallocated shares are used to repay the outstanding debt of the ESOP. The ESOP trust’s outstanding loan bears interest at prime, adjustable each January 1 st As the debt is repaid, shares are released from the collateral and allocated to qualified employees based on the proportion of payments made during the year to the remaining amount of payments due on the loan through maturity. Accordingly, the shares pledged as collateral are reported as unallocated common stock held by the ESOP shares in the Consolidated Balance Sheet. As shares are released from collateral, the Company reports compensation expense equal to the current market price of the shares, and the shares become outstanding for earnings-per-share computations. The Company recognized ESOP expense of $ and $ , for th e years ended September 30, 2022 and 2021 , respectively . The following table presents the components of the ESOP shares: 2022 2021 Allocated shares 390,547 398,180 Shares committed to be released 33,962 33,962 Unreleased shares 645,274 690,556 Total ESOP shares 1,069,783 1,122,698 Fair value of unreleased shares (in thousands) $ 13,170 $ 11,387 Equity Incentive Plan The Company previously maintained the ESSA Bancorp, Inc. 2007 Equity Incentive Plan (the “Plan”). The Plan provided for a total of 2,377,326 shares of common stock for issuance upon the grant or exercise of awards. Of the shares available under the Plan, 1,698,090 were available to be issued in connection with the exercise of stock options and 679,236 were available to be issued as restricted stock. The Plan allowed for the granting of non-qualified stock options (“NSOs”), incentive stock options (“ISOs”), and restricted stock. Options under the plan were granted at no less than the fair value of the Company’s common stock on the date of the grant. As of the effective date of the 2016 Equity Incentive Plan (detailed below), no further grants will be made under the plan and forfeitures of outstanding awards under the plan will be added to the shares available under the 2016 Equity Incentive Plan. The Company replaced the 2007 Equity Incentive Plan with the ESSA Bancorp, Inc. 2016 Equity Incentive Plan (the “2016 Plan”). The 2016 Plan provides for a total of 250,000 shares of common stock for issuance upon the grant or exercise of awards. The 2016 Plan allows for the granting of restricted stock, restricted stock units, incentive stock options and non-qualified stock options. The Company classifies share-based compensation for employees and outside directors within “Compensation and employee benefits” in the Consolidated Statement of Income to correspond with the same line item as compensation paid. Restricted stock shares outstanding at September 30, 2022 vest over periods ranging from 1 year to 3 years. The product of the number of shares granted and the grant date market price of the Company’s common stock determines the fair value of restricted shares under the Company’s restricted stock plan. The Company expenses the fair value of all share based compensation grants over the requisite service period. During the years ended September 30, 2022 and 2021, the Company recorded $517,000 and $515,000 of share-based compensation expense consisting of restricted stock expense. Expected future compensation expense relating to the restricted shares outstanding, at September 30, 2022 is $519,000 over the remaining vesting period of 3.0 years. The following is a summary of the status of the Company’s nonvested restricted stock as of September 30, 2022, and changes therein during the year then ended: Number of Restricted Weighted- Average Grant Date Fair Value Nonvested at September 30, 2021 42,116 $ 13.99 Granted 34,080 16.48 Vested (33,011 ) 15.39 Forfeited (7,546 ) 14.91 Nonvested at September 30, 2022 35,639 $ 14.88 Defined Benefit Plan The Bank sponsors a trusteed, noncontributory defined benefit pension plan covering substantially all employees and officers. The plan calls for benefits to be paid to eligible employees at retirement based primarily upon years of service with the Bank and compensation rates near retirement. The Bank’s funding policy is to make annual contributions, if needed, based upon the funding formula developed by the plan’s actuary. In February 2017, the Bank amended the defined benefit pension plan to provide that no additional participants would enter the plan and no additional benefits would accrue beyond February 28, 2017. The following table sets forth the change in plan assets and benefit obligation at September 30 (in thousands): 2022 2021 Change in benefit projected obligation: Projected benefit obligation at beginning of year $ 20,895 $ 20,315 Service cost - - Interest cost 556 450 Actuarial (gains) losses (5,129 ) 599 Benefits paid (3,546 ) (469 ) Projected benefit obligation at end of year 12,776 20,895 Change in plan assets: Fair value of plan assets at beginning of year 23,248 20,253 Actual return on plan assets (3,152 ) 3,464 Contributions - - Benefits paid (3,545 ) (469 ) Fair value of plan assets at end of year 16,551 23,248 Funded status $ 3,775 $ 2,353 Amounts not yet recognized as a component of net periodic pension cost at September 30 (in thousands): 2022 2021 Amounts recognized in accumulated other comprehensive income consist of: Net loss $ 1,401 $ 2,413 The accumulated benefit obligation for the defined benefit pension plan was $12.8 million and $20.9 million at September 30, 2022 and 2021, respectively.

The Bank’s defined benefit pension plan weighted-average asset allocations at September 30, 2022 and 2021 by asset category, are as follows: September 30, Asset Category 2022 2021 Fixed income securities 40.3 % 40.6 % Equity securities 59.4 59.2 Other 0.3 0.2 Total 100.0 % 100.0 % The Bank believes that the plan’s risk and liquidity position are, in large part, a function of the asset class mix. The Bank desires to utilize a portfolio mix that results in a balanced investment strategy. Three asset classes are outlined, as above. The target allocations of these classes are as follows: equity securities, 65 percent, and cash and fixed income securities, 35 percent. Cash Flows The Bank does not expect to make any contributions to its pension plan in fiscal 2023. Estimated future benefit payments, which reflect expected future service, as appropriate, are as follows (in thousands): 2023 $ 768 2024 658 2025 1,368 2026 974 2027 1,419 2028-2032 3,663 401(k) Plan The Bank also has a savings plan qualified under Section 401(k) of the Internal Revenue Code, which covers substantially all employees over 21 years of age. Employees can contribute to the plan, but are not required to. Employer contributions were reinstated in March 2017. Employer contributions are allocated based on employee contribution levels. The expense related to the plan for the year ended September 30, 2022 and 2021 was $496,000 and $489,000, respectively. Supplemental Executive Retirement Plan The Bank maintains a salary continuation agreement with certain executives of the Bank, which provides for benefits upon retirement to be paid to the executive for no less than 192 months, unless the executive elects to receive the present value of the payments as a lump sum. The Bank has recorded accruals of $2.6 million and $2.3 million at September 30, 2022 and 2021, respectively which represent the estimated present value (using a discount rate of 6.00 percent) of the benefits earned under this agreement. There was $63,000 and $66,000 in expense related to the supplemental executive retirement plan for the years ended September 30, 2022 and 2021, respectively.

Regulatory Restrictions	13. REGULATORY RESTRICTIONS Reserve Requirements The Bank is required to maintain reserve funds in cash or in deposit with the Federal Reserve Bank. In response to the pandemic, the Federal Reserve Bank reduced the reserve requirement to zero effective March 26, 2020. As a result, there was no required reserve at September 30, 2022 and 2021. Dividend Restrictions Federal banking laws, regulations, and policies limit the Bank’s ability to pay dividends to the Company. Dividends may be declared and paid by the Bank only out of net earnings for the then current year. A dividend may not be declared or paid if it would impair the general reserves of the Bank as required to be maintained under the Pennsylvania Banking.

Regulatory Capital Requirements	14. REGULATORY CAPITAL REQUIREMENTS Federal regulations require the Bank and the Company to maintain certain minimum amounts of capital. Specifically, the Bank is required to maintain certain minimum dollar amounts and ratios of Total and Tier 1 capital to risk-weighted assets, of Tier 1 capital to average total assets, and common equity Tier 1 capital to risk-weighted assets. Bank holding companies are generally subject to statutory capital requirements, which were implemented by certain of the new capital regulations described above that became effective on January 1, 2015. However, the Small Banking Holding Company Policy Statement exempts certain small bank holding companies like the Company from those requirements provided that they meet certain conditions. In addition to the capital requirements, the Federal Deposit Insurance Corporation Improvement Act (“FDICIA”) established five capital categories ranging from “well capitalized” to “critically undercapitalized.” Should any institution fail to meet the requirements to be considered “adequately capitalized,” it would become subject to a series of increasingly restrictive regulatory actions. Management believes that, as of September 30, 2022, the Bank met all capital adequacy requirements to which it is subject. As of September 30, 2022, and 2021, the FDIC categorized the Bank and the Federal Reserve categorized the Company as well capitalized under the regulatory framework for prompt corrective action. To be classified as a well-capitalized financial institution, Total risk-based, Tier 1 risk-based, common equity Tier 1 capital and Tier 1 leverage capital must be at least 10 percent, 8 percent, 6.5 percent, and 5 percent, respectively. There have been no conditions or events since the notification that management believes have changed the Bank’s or the Company’s category. The Bank’s actual capital ratios for the years ended September 30 are presented in the following table (dollars in thousands): 2022 2021 Amount Ratio Amount Ratio Total capital (to risk-weighted assets) Actual $ 211,390 13.3 % $ 199,019 14.5 % For capital adequacy purposes 126,843 8.0 110,039 8.0 To be well capitalized 158,554 10.0 137,549 10.0 Tier 1 capital (to risk-weighted assets) Actual $ 192,810 12.2 % $ 181,814 13.2 % For capital adequacy purposes 95,132 6.0 82,529 6.0 To be well capitalized 126,843 8.0 110,039 8.0 Common equity tier 1 capital (to risk-weighted assets) Actual $ 192,810 12.2 % $ 181,814 13.2 % For capital adequacy purposes 71,349 4.5 61,897 4.5 To be well capitalized 103,060 6.5 89,407 6.5 Tier 1 capital (to adjusted assets) Actual $ 192,810 10.5 % $ 181,814 10.0 % For capital adequacy purposes 73,656 4.0 72,390 4.0 To be well capitalized 92,070 5.0 90,488 5.0

Fair Value Disclosures [Abstract]
Fair Value	15. FAIR VALUE The following disclosures show the hierarchal disclosure framework associated within the level of pricing observations utilized in measuring assets and liabilities at fair value. The definition of fair value maintains the exchange price notion in earlier definitions of fair value but focuses on the exit price of the asset or liability. The exit price is the price that would be received to sell the asset or paid to transfer the liability adjusted for certain inherent risks and restrictions. Expanded disclosures are also required about the use of fair value to measure assets and liabilities. Assets and Liabilities Required to be Measured and Reported at Fair Value on a Recurring Basis The following tables provide the fair value for assets required to be measured and reported at fair value on a recurring basis on the Consolidated Balance Sheet as of September 30, 2022 and September 30, 2021 by level within the fair value hierarchy (in thousands).

Fair Value Measurement Using Significant Unobservable Inputs (Level III) September 30, 2022 September 30, 2021 Beginning balance $ 11,112 $ 8,260 Purchases, sales, issuances, settlements, net 1,515 2,608 Total unrealized gain: Included in earnings - - Included in other comprehensive income (753 ) 244 Transfers into Level III - - Transfers out of Level III (4,500 ) - $ 7,374 $ 11,112 Each financial asset and liability is identified as having been valued according to a specified level of input, 1, 2 or 3. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Fair values determined by Level 2 inputs utilize inputs other than quoted prices included in Level 1 that are observable for the asset, either directly or indirectly. Level 2 inputs include quoted prices for similar assets in active markets, and inputs other than quoted prices that are observable for the asset or liability. Level 3 inputs are unobservable inputs for the asset, and include situations where there is little, if any, market activity for the asset or liability. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy, within which the fair value measurement in its entirety falls, has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset. The measurement of fair value should be consistent with one of the following valuation techniques: market approach, income approach, and/or cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities (including a business). For example, valuation techniques consistent with the market approach often use market multiples derived from a set of comparable. Multiples might lie in ranges with a different multiple for each comparable. The selection of where within the range the appropriate multiple falls requires judgment, considering factors specific to the measurement (qualitative and quantitative). Valuation techniques consistent with the market approach include matrix pricing. Matrix pricing is a mathematical technique used principally to value debt securities without relying exclusively on quoted prices for the specific securities, but rather by relying on a security’s relationship to other benchmark quoted securities. Most of the securities classified as available for sale are reported at fair value utilizing Level 2 inputs. For these securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quoted market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. Securities reported at fair value utilizing Level 1 inputs are limited to actively traded equity securities whose market price is readily available from the New York Stock Exchange or the NASDAQ exchange. A few securities are valued using Level 3 inputs, all of these are classified as available for sale and are reported at fair value using Level 3 inputs. Assets and Liabilities Required to be Measured and Reported on a Non-Recurring Basis The following tables provide the fair value for assets required to be measured and reported at fair value on a non recurring basis on the Consolidated Balance Sheet as of September 30, 2022 and September 30, 2021 by level within the fair value hierarchy: September 30, 2022 Level I Level II Level III Total Fair Value Financial assets: Foreclosed real estate $ - $ - $ 29 $ 29 Impaired loans - - 14,151 14,151 September 30, 2021 Level I Level II Level III Total Fair Value Financial assets: Foreclosed real estate $ - $ - $ 461 $ 461 Impaired loans - - 15,122 15,122 The following tables present additional quantitative information about assets measured at fair value on a nonrecurring basis and for which the Company has utilized Level 3 inputs to determine fair value: Quantitative Information About Level III Fair Value Measurements Fair Value Estimate Valuation Techniques Unobservable Input Range (Weighted September 30, 2022 Impaired loans $ 14,151 Appraisal of collateral (1) Appraisal adjustments (2) 0% to 35% (20.6%) Foreclosed real estate owned 29 Appraisal of collateral (1) Appraisal adjustments (2) 20% (20.0%) September 30, 2021 Impaired loans $ 15,122 Appraisal of collateral (1) Appraisal adjustments (2) 0% to 50% (24.1%) Foreclosed real estate owned 461 Appraisal of collateral (1) Appraisal adjustments (2) 20% to 35% (20.1%) (1) Fair value is generally determined through independent appraisals of the underlying collateral, which generally include various level 3 inputs which are not identifiable. (2) Appraisals may be adjusted by management for qualitative factors such as economic conditions and estimated liquidation expenses. The range of liquidation expenses and other appraisal adjustments are presented as a percent of the appraisal. Investment Securities Available for Sale The fair value of securities available for sale are determined by obtaining quoted market prices on nationally recognized securities exchanges (Level 1), or matrix pricing (Level 2), which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted market prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted prices. For certain securities which 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 (Level 3). In the absence of such evidence, management’s best estimate is used. Management’s best estimate consists of both internal and external support on certain Level 3 investments. Internal cash flow models using a present value formula that includes assumptions market participants would use along with indicative exit pricing obtained from broker/dealers (where available) are used to support fair values of certain Level 3 investments, if applicable. Equity Securities The fair value of equity securities are determined by obtaining quoted market prices on nationally recognized securities exchanges (Level 1). Impaired Loans The Company has measured impairment on impaired loans generally based on the fair value of the loan’s collateral. Evaluating impaired loan collateral is based on Level II inputs utilizing outside appraisals. Those impaired loans for which management incorporates significant adjustments for sales costs and other discount assumptions regarding market conditions are considered Level III fair values. The fair value consists of the loan balances of $14.5 million less their valuation allowances of $351,000 at September 30, 2022. The fair value consists of the loan balances of $15.6 million less their valuation allowances of $428,000 at September 30, 2021. Foreclosed Real Estate Owned Foreclosed real estate owned is measured at fair value, less cost to sell at the date of foreclosure; valuations are periodically performed by management; and the assets are carried at fair value, less cost to sell. Income and expenses from operations and changes in valuation allowance are included in the net expenses from foreclosed real estate. Derivatives The Company’s objectives in using interest rate derivatives are to add stability to interest income and expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company has entered into interest rate swaps as part of its interest rate risk management strategy. These interest rate swaps are designated as cash flow hedges and involve the receipt of variable rate amounts from a counterparty in exchange for the Company making fixed payments. The fair value of the swap asset and liability is based on an external derivative model using data inputs as of the valuation date and are classified Level 2. Assets and Liabilities not Required to be Measured and Reported at Fair Value The methods and assumptions used by the Company in estimating fair values of financial instruments at September 30, 2022 and 2021 is in accordance with ASC Topic 825, Financial Instruments September 30, 2022 Carrying Value Level I Level II Level III Total Fair Value Financial assets: Loans receivable, net $ 1,435,783 $ - $ - $ 1,351,823 $ 1,351,823 Mortgage servicing rights 788 - - 1,390 1,390 Investment securities held to maturity 57,285 - 47,546 - 47,546 Financial liabilities: Deposits 1,380,021 1,246,353 - 128,533 1,374,886 Short-term borrowings 230,810 - - 215,287 215,287 September 30, 2021 Carrying Value Level I Level II Level III Total Fair Value Financial assets: Loans receivable, net $ 1,340,853 $ - $ - $ 1,353,420 $ 1,353,420 Mortgage servicing rights 763 - - 998 998 Investment securities held to maturity 21,483 - 21,249 - 21,249 Financial liabilities: Deposits 1,636,115 1,426,191 - 209,660 1,635,851 For Cash and Cash Equivalents, Accrued Interest Receivable, Regulatory Stock, Bank Owned Life Insurance, Short-Term Borrowings, Advances by Borrowers for Taxes and Insurance, and Accrued Interest Payable the carrying value is a reasonable estimate of the fair value and are considered Level 1 measurements.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	1 7 . DERIVATIVES AND HEDGING ACTIVITIES Risk Management Objective of Using Derivatives The Company is exposed to certain risk arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments. Fair Values of Derivative Instruments on the Consolidated Balance Sheet The table below presents the fair value of the Company’s derivative financial instruments as well as their classification on the Consolidated Balance Sheet as of September 30, 2022 and 2021, (in thousands). Fair Values of Derivative Instruments Asset Derivatives As of September 30, 2022 As of September 30, 2021 Hedged Item Notional Amount Balance Sheet Location Fair Value Notional Amount Balance Sheet Location Fair Value Brokered Deposits $ - Derivative and hedging assets $ - $ 175,000 Derivative and hedging assets $ 1,247 FHLB Advances 225,000 Derivative and hedging assets 15,310 - Derivative and hedging assets - Commercial Loans 79,602 Derivative and hedging assets 9,171 71,326 Derivative and hedging assets 1,307 Total derivatives designated as hedging instruments $ 304,602 $ 24,481 $ 246,326 $ 2,554 Fair Values of Derivative Instruments Liability Derivatives As of September 30, 2022 As of September 30, 2021 Hedged Item Notional Amount Balance Sheet Location Fair Value Balance Sheet Location Fair Value Brokered Deposits $ - Derivative and hedging liabilities $ - $ 60,000 Derivative and hedging liabilities $ 452 Commercial Loans 111,668 Derivative and hedging liabilities 9,176 103,831 Derivative and hedging liabilities 1,304 Total derivatives designated as hedging instruments $ 111,668 $ 9,176 $ 163,831 $ 1,756 Cash Flow Hedges of Interest Rate Risk The Company’s objectives in using interest rate derivatives are to add stability to interest income and expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company has entered into interest rate swaps as part of its interest rate risk management strategy. These interest rate swaps are designated as cash flow hedges and involve the receipt of variable rate amounts from a counterparty in exchange for the Company making fixed payments. As of September 30, 2022, the Company had ten interest rate swaps with a notional of $225 million associated with the Company’s cash outflows associated with various FHLB advances and $191 million associated with commercial loans. As of September 30, 2021, the Company had eleven interest rate swaps with a notional of $235 million associated with the Company’s cash outflows associated with various brokered deposits and $175 million associated with commercial loans. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is initially reported in other comprehensive income (outside of earnings), net of tax, and subsequently reclassified to earnings when the hedged transaction affects earnings, and the ineffective portion of changes in the fair value of the derivative is recognized directly in earnings. The Company assesses the effectiveness of each hedging relationship by comparing the changes in cash flows of the derivative hedging instrument with the changes in cash flows of the designated hedged transactions. The Company did not recognize any hedge ineffectiveness in earnings during the periods ended September 30, 2022 and 2021. 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 12 months ended September 30, 2022 and 2021, the Company had $823,000 in gains and $2.0 million in losses classified to interest expense, respectively. During the next twelve months, the Company estimates that $8.2 million will be reclassified as a decrease in interest expense. The table below presents the effect of the Company’s cash flow hedge accounting on Accumulated Other Comprehensive Income for the periods ended September 30, 2022 and 2021 (in thousands).

The Company also has agreements with certain of its derivative counterparties that contain a provision where if the Company fails to maintain its status as a well / adequately capitalized institution, then the counterparty could terminate the derivative positions and the Company would be required to settle its obligations under the agreements. As of September 30, 2022 the Company had derivatives in a net asset position and was not required to post collateral against its obligations under these agreements. As of September 30, 2021 the Company had derivatives in a net liability position and was required to post $640,000 in collateral against its obligations under these agreements. If the Company had breached any of these provisions at September 30, 2022 and 2021, it could have been required to settle its obligations under the agreements at the termination value.

Revenue Recognition

Revenue From Contract With Customer [Abstract]
Revenue Recognition	1 8 . REVENUE RECOGNITION The Company accounts for its applicable revenue in accordance with ASC Topic 606 – Revenue from Contracts with Customers. Topic 606 does not apply to revenue associated with interest income on financial instruments, including loans and securities. Additionally, certain noninterest income streams, such as income from bank-owned life insurance, gains on loans sold, and gains and losses on sales of debt and equity securities, are out of scope of Topic 606. The Company has evaluated the nature of its contracts with customers and determined that further disaggregation beyond what is presented in the Consolidated Statement of Income was not necessary. The main types of non interest income within the scope of the standard are: Trust and Investment Fees Trust and asset management income is primarily comprised of fees earned from the management and administration of trusts and other customer assets. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the month-end market value of the assets under management and the applicable fee rate. Payment is generally received a few days after month end through a direct charge to customer’s accounts. The Company does not earn performance-based incentives. Optional services such as real estate sales and tax return preparation services are also available to existing trust and asset management customers. The Company’s performance obligation for these transactional-based services is generally satisfied, and related revenue recognized, at a point in time (i.e. as incurred). Payment is received shortly after services are rendered. Service Charges on Deposit Accounts Service charges on deposit accounts consist of account analysis fees (i.e. net fees earned on analyzed business and public checking accounts), monthly service fees, check orders, and other deposit account related fees. The Company’s performance obligation for account analysis fees and monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. Check orders and other deposit account related fees are largely transactional based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, at a point in time. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers’ accounts. Fees, Exchange, and Other Service Charges Fees, interchange, and other service charges are primarily comprised of debit card income, ATM fees, cash management income, and other services charges. Debit card income is primarily comprised of interchange fees earned whenever the Company’s debit cards are processed through card payment networks such as Mastercard. ATM fees are primarily generated when a Company cardholder uses a non-Company ATM or a non-Company cardholder uses a company ATM. Other service charges include revenue from processing wire transfers, bill pay service, cashier’s checks, and other services. The Company’s performance obligation for fees, exchange, and other service charges are largely satisfied, and related revenue recognized when the services are rendered or upon completion. Payment is typically received immediately or in the following month. Insurance Commissions Insurance income primarily consists of commissions received on product sales. The Company acts as an intermediary between the Company’s customer and the insurance carrier. The Company’s performance obligation is generally satisfied upon the issuance of the policy. Shortly after the policy is issued, the carrier remits the commission payment to the Company, and the Company recognizes the revenue.

Integrated Abstract Incorporated is a Pennsylvania Corporation that provided title insurance services and is currently inactive. All significant intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements The accounting principles followed by the Company and its subsidiary and the methods of applying these principles conform to U.S. generally accepted accounting principles and to general practice within the banking industry. In preparing the consolidated financial statements, the Company is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the Consolidated Balance Sheet date and related revenues and expenses for the period. Actual results could differ from those estimates.
Securities	Securities The Company determines the appropriate classification of debt securities at the time of purchase and reevaluates such designation as of each balance sheet date. Securities classified as available for sale are those securities 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 maturity mix of the Company’s assets and liabilities, liquidity needs, regulatory capital considerations, and other similar factors. Securities available for sale are carried at fair value. Unrealized gains and losses are reported in other comprehensive income (loss), net of the related deferred tax effects. 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 using the interest method over the period to maturity. Declines in the fair value of 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, the Company 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; and (3) the Company’s intent to sell the security or whether it’s more likely than not that the Company would be required to sell the security before its anticipated recovery in market value. Securities classified as held-to-maturity are those that the Company has the positive intent and ability to hold until maturity. These securities are reported at amortized cost. The fair market value of the equity securities tends to fluctuate with the overall equity markets as well as the trends specific to each institution. The equity securities portfolio is reviewed in a similar manner as that of the debt securities with greater emphasis placed on the length of time the market value has been less than the carrying value and the financial sector outlook. The Company also reviews dividend payment activities, levels of non-performing assets and loan loss reserves. The starting point for the equity analysis is the length and severity of market value decline. The realized loss is recognized as impairment charges on securities on the consolidated statements of income. The previous cost basis less the OTTI recognized in earnings becomes the new cost basis of the investment. Certain equity securities that do not have a readily determinable fair value are stated at cost, adjusted for observable price changes in orderly transactions for identical or similar investments of the same issuer. These securities include restricted stock of the Federal Home Loan Bank of Pittsburgh, as well as other equity securities.
Loans Receivable	Loans Receivable Loans receivable that the Company has the intent and ability to hold for the foreseeable future or until maturity or payoff are stated at their outstanding unpaid principal balances, net of an allowance for loan losses and any deferred fees and costs. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the yield (interest income) of the related loans. The Company is generally amortizing these amounts over the contractual life of the loan. The accrual of interest is generally discontinued when the contractual payment of principal or interest has become 90 days past due or the Company has serious doubts about further collectability of principal or interest, even though the loan is currently performing. A loan may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan is placed on nonaccrual status, unpaid interest credited to income is reversed. Interest received on nonaccrual loans generally is either applied against principal or reported as interest income, according to the Company’s judgment as to the collectability of principal. Generally, loans are restored to accrual status when the obligation is brought current and has performed in accordance with the contractual terms for a reasonable period of time and the ultimate collectability of the total contractual principal and interest is no longer in doubt.
Loans Acquired	Loans Acquired Loans acquired including loans that have evidence of deterioration of credit quality since origination and for which it is probable, at acquisition, that the Company will be unable to collect all contractually required payments receivable, are initially recorded at fair value (as determined by the present value of expected future cash flows) with no valuation allowance. Loans are evaluated individually to determine if there is evidence of deterioration of credit quality since origination. The difference between the undiscounted cash flows expected at acquisition and the investment in the loan, or the “accretable yield,” is recognized as interest income on a level-yield method over the life of the loan. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition, or the “non-accretable difference,” are not recognized as a yield adjustment or as a loss accrual or a valuation allowance. Increases in expected cash flows subsequent to the initial investment are recognized prospectively through adjustment of the yield on the loan over its remaining estimated life. Decreases in expected cash flows are recognized immediately as impairment. Any valuation allowances on these impaired loans reflect only losses incurred after acquisition. For purchased loans acquired that are not deemed impaired at acquisition, credit discounts representing the principal losses expected over the life of the loan are a component of the initial fair value. Loans are aggregated and accounted for as a pool of loans if the loans being aggregated have common risk characteristics. Subsequent to the purchase date, the methods utilized to estimate the required allowance for credit losses for these loans is similar to originated loans; however, the Company records a provision for loan losses only when the required allowance exceeds any remaining credit discounts. The remaining differences between the purchase price and the unpaid principal balance at the date of acquisition are recorded in interest income over the life of the loans.
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses is established through provisions for loan losses charged against income. Loans deemed to be uncollectible are charged against the allowance for loan losses, and subsequent recoveries, if any, are credited to the allowance for loan losses. The allowance for loan losses is maintained at a level by management which represents the evaluation of known and inherent risks in the loan portfolio at the Consolidated Balance Sheet date. Management’s periodic evaluation of the adequacy of the allowance is based on the Company’s past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral, composition of the loan portfolio, current economic conditions, and other relevant factors. This evaluation is inherently subjective, since it requires material estimates that may be susceptible to significant change, including the amounts and timing of future cash flows expected to be received on impaired loans. The allowance for loan losses consists of specific and general components. The specific component relates to loans that are classified as impaired. For such loans an allowance for loan losses 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. The general component covers nonclassified loans and is based on historical loss experience adjusted for qualitative factors. All loans are considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement and all loan types are considered impaired if the loan is restructured in a troubled debt restructuring. 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 the 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. Impairment is measured on a loan-by-loan basis for commercial and construction loans by the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral-dependent. Large groups of smaller-balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer and residential mortgage loans for impairment disclosures unless such loans are part of a larger relationship that is impaired or classified as a troubled debt restructuring or is more than 180 days past due. A loan is considered to be a troubled debt restructuring (“TDR”) loan when the Company grants a concession to the borrower because of the borrower’s financial condition that it would not otherwise consider. Such concessions include the reduction of interest rates, forgiveness of principal or interest, or other modifications of interest rates that are less than the current market rate for new obligations with similar risk. TDR loans that are in compliance with their modified terms and that yield a market rate may be removed from the TDR status after one year of performance.
Regulatory Stock	Regulatory Stock Regulatory stock consists of Federal Home Loan Bank (“FHLB”) of Pittsburgh stock and Atlantic Community Bankers Bank stock. Regulatory stock is carried at cost. The Company is a member of the Federal Home Loan Bank System and holds stock in the Federal Home Loan Bank of Pittsburgh. As a member, the Company maintains an investment in the capital stock of the FHLB of Pittsburgh in an amount not less than 10 basis points of the outstanding member asset value plus 4.0 percent of its outstanding FHLB borrowings, as calculated throughout the year. The equity security is accounted for at cost and classified separately on the Consolidated Balance Sheet. The stock is bought from and sold to the FHLB based upon its $100 par value. The stock does not have a readily determinable fair value and as such is classified as restricted stock, carried at cost and evaluated by management. The stock’s value is determined by the ultimate recoverability of the par value rather than by recognizing temporary declines. The determination of whether the par value will ultimately be recovered is influenced by criteria such as the following: (a) The significance of the decline in net assets of the FHLB as compared to the capital stock amount and the length of time this situation has persisted; (b) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance; (c) the impact of legislative and regulatory changes on the customer base of the FHLB; and (d) the liquidity position of the FHLB. With consideration given to these factors, management concluded that the stock was not impaired at September 30, 2022.
Loan Servicing	Loan Servicing Servicing assets are recognized as separate assets when rights are acquired through purchase or through sale of financial assets. Capitalized servicing rights are reported in other assets and are amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets. Servicing assets are evaluated for impairment based upon a third-party appraisal. Fair value is determined using prices for similar assets with similar characteristics, when available, or based upon discounted cash flows using market-based assumptions. Impairment is recognized through a valuation allowance to the extent that fair value is less than the capitalized amount. The Company’s loan servicing assets a t September 30, 2022 and 2021 , were not impaired. Total servicing assets included in other assets as of September 30, 2022 and 2021 , were $ 788,000 and $ , respectively .
Premises and Equipment	Premises and Equipment Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the useful lives of the related assets, which range from 10 to 40 years for buildings, land improvements, and leasehold improvements and three to seven years for furniture, fixtures, and equipment. Expenditures for maintenance and repairs are charged to operations as incurred. Costs of major additions and improvements are capitalized.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities The Company records all derivatives on the Consolidated Balance Sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. In accordance with the FASB’s fair value measurement guidance, the Company has elected to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio.
Bank-Owned Life Insurance ("BOLI")	Bank-Owned Life Insurance (“BOLI”) The Company owns insurance on the lives of a certain group of key employees. The policies were purchased to help offset the increase in the costs of various fringe benefit plans, including healthcare. The cash surrender value of these policies is included as an asset on the Consolidated Balance Sheet, and any increase in cash surrender value is recorded as noninterest income on the Consolidated Statement of Income. In the event of the death of an insured individual under these policies, the Company would receive a death benefit which would be recorded as noninterest income.
Foreclosed Real Estate	Foreclosed Real Estate Real estate owned acquired in settlement of foreclosed loans is carried at fair value minus estimated costs to sell. At acquisition of real estate acquired in settlement of foreclosed loans, the excess of the remaining loan balance over the asset’s estimated fair value less cost to sell is charged off against the allowance for loan losses. Subsequent declines in the asset’s value are recognized as noninterest expense in the Consolidated Statement of Income. Operating expenses of such properties, net of related income, are expensed in the period incurred.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill is not amortized, but it is tested at least annually for impairment in the fourth quarter, or more frequently if indicators of impairment are present. If the estimated current fair value of a reporting unit exceeds its carrying value, no additional testing is required and an impairment loss is not recorded. The Company uses market capitalization and multiples of tangible book value methods to determine the estimated current fair value of its reporting unit. Based on this analysis, no impairment was recorded in 2022 or 2021. The other intangible assets are assigned useful lives, which are amortized on an accelerated basis over their weighted-average lives. The Company periodically reviews intangible assets for impairment as events or changes in circumstances indicate that the carrying amount of such asset may not be recoverable. Based on these reviews, no impairment was recorded in 2022 and 2021. The following tables provide information for the carrying amount of goodwill and intangible assets (in thousands): Goodwill 2022 2021 Balance at beginning of year $ 13,801 $ 13,801 Goodwill acquired - - Balance at end of year $ 13,801 $ 13,801 Intangible assets 2022 2021 Balance at beginning of year $ 520 $ 791 Intangible assets acquired - - Amortization (239 ) (271 ) Balance at end of year $ 281 $ 520 Amortizable intangible assets were composed of the following (in thousands): September 30, 2022 2021 Gross Amount Accumulated Amortization (dollars in thousands) Core deposit intangible $ 4,787 $ 4,506 $ 4,267 2022 2021 Aggregate amortization expense: As of the years ended September 30 $ 239 $ 271 Estimated future amortization expense (in thousands): 2023 $ 190 2024 91 $ 281
Employee Benefit Plans	Employee Benefit Plans The Bank maintains a noncontributory, defined benefit pension plan for all employees who have met age and length of service requirements. The Bank also maintains a defined contribution Section 401(k) plan covering eligible employees. The Company created an ESOP for the benefit of employees who meet certain eligibility requirements. The Company makes cash contributions to the ESOP on an annual basis. The Company maintains an equity incentive plan to provide for issuance or granting of shares of common stock for stock options or restricted stock. The Company has recorded stock-based employee compensation cost using the fair value method as allowed under generally accepted accounting principles. Management estimated the fair values of all option grants using the Black-Scholes option-pricing model. Management estimated the expected life of the options using the simplified method as allowed under generally accepted accounting principles. The risk-free rate was determined utilizing the treasury yield for the expected life of the option contract.
Advertising Costs	Advertising Costs The Company expenses all advertising expenditures 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 of 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 their maturity.
Income Taxes	Income Taxes Deferred tax assets and liabilities are reflected based on the differences between the financial statement and the income tax basis of assets and liabilities using the enacted marginal tax rates. Deferred income tax expense and benefit are based on the changes in the deferred tax assets or liabilities from period to period. Deferred tax assets and liabilities are reflected at currently enacted income tax rates applicable to the period in which such items are expected to be realized or settled. As changes in tax rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. The Company files a consolidated federal income tax return and individual state income tax returns. The Company prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Benefits from tax positions should be recognized in the financial statements only when it is more likely than not that the tax position will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should be derecognized in the first subsequent financial reporting period in which that threshold is no longer met.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company has defined cash and cash equivalents as cash and due from banks and interest-bearing deposits with other institutions with original maturities of less than 90 days.
Earnings Per Share	Earnings Per Share The Company provides dual presentation of basic and diluted earnings per share. Basic earnings per share are calculated utilizing net income as reported as the numerator and average shares outstanding as the denominator. The computation of diluted earnings per share differs in that the dilutive effects of any options are adjusted for in the denominator.
Comprehensive Income (Loss)	Comprehensive Income (Loss) The Company is required to present comprehensive income (loss) and its components in a full set of general-purpose financial statements for all periods presented. Other comprehensive income (loss) is composed of net unrealized holding gains or losses on its available-for-sale investment and mortgage-backed securities portfolio and derivative instruments, and changes in unrecognized pension cost.
Fair Value Measurements	Fair Value Measurements The Company groups assets and liabilities carried at fair value in three levels, based on the markets in which the assets are traded and the reliability of the assumptions used to determine fair value. These levels are: • Level I – Valuation is based upon quoted prices for identical instruments traded in active markets. • Level II – Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. • Level III – Valuation is generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect the Company’s own estimates of assumptions that market participants would use in pricing the asset. The Company determines fair value based on 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. It is our policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements, in accordance with the fair value hierarchy in generally accepted accounting principles. Fair value measurements for most of the Company’s assets are obtained from independent pricing services that we have engaged for this purpose. When available, the Company, or the Company’s independent pricing service, use quoted market prices to measure fair value. If market prices are not available, fair value measurement is based upon models that incorporate available trade, bid, and other market information. Subsequently, all of the Company’s financial instruments use either of the foregoing methodologies to determine fair value adjustments recorded to our financial statements. In certain cases, however, when market observable inputs for model-based valuation techniques may not be readily available, we are required to make judgments about assumptions market participants would use in estimating the fair value of financial instruments. The degree of management judgment involved in determining the fair value of a financial instrument is dependent upon the availability of quoted market prices or observable market parameters. For financial instruments that trade actively and have quoted market prices or observable market parameters, there is minimal subjectivity involved in measuring fair value. When observable market prices and parameters are not fully available, management judgment is necessary to estimate fair value. In addition, changes in the market conditions may reduce the availability of quoted prices or observable data. When market data is not available, we use valuation techniques requiring more management judgment to estimate the appropriate fair value measurement. Therefore, the results cannot be determined with precision and may not be realized in an actual sale or immediate settlement of the asset. Additionally, there may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, that could significantly affect the results of current or future valuations.
Reclassification of Comparative Amounts	Reclassification of Comparative Amounts Certain items previously reported have been reclassified to conform to the current year’s reporting format. Such reclassifications did not affect consolidated net income or consolidated stockholders’ equity.
Adoption of New Standards and Recent Accounting Pronouncements	Adoption of New Standards ASC 715 In August 2018, the FASB issued ASU 2018-14, Compensation – Retirement Benefits (Topic 715-20). This Update amends to add, remove and clarify disclosure requirements related to defined benefit pension and other postretirement plans. The Update eliminates the requirement to disclose the amounts in accumulated other comprehensive income expected to be recognized as part of net periodic benefit cost over the next year. The Update also removes the disclosure requirements for the effects of a one-percentage-point change on the assumed health care costs and the effect of this change in rates on service cost, interest cost and the benefit obligation for postretirement health care benefits. This Update is effective for public business entities for fiscal years ending after December 15, 2020, and must be applied on a retrospective basis. The adoption of ASU 2018-14 did not have a significant impact on the Company’s financial statements. In January 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting In October 2020, the FASB issued ASU 2020-08, Codification Improvements to Subtopic 310-20, Receivables – Nonrefundable Fees and Other Costs, In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848) 2020 effectiveness for periods after December 31, 2022, except for certain hedging relationships existing as of December 31, 2022, that apply certain optional expedients in which the accounting effects are recorded through the end of the hedging relationship. The adoption of ASU 2021-01 did no t have a significant impact on the Company’s financial statements. Recent Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments Financial Instruments ‒ Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842) In May 2019, the FASB issued ASU 2019-05, Financial Instruments – Credit Losses (Topic 326) In November 2019, the FASB issued ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments – Credit Losses In March 2020, the FASB issued ASU 2020-03 , Codification Improvements to Financial Instruments. Financial Instruments related to ASU 2016-13 for entities that have not yet adopted that guidance are effective upon adoption of the amendments in ASU 2016-13. Early adoption is not permitted before an entity’s adoption of ASU 2016-13. Amendments related to ASU 2016-13 for entities that have adopted that guidance are effective for fiscal years beginning after December 15, 2019, including interim periods within those years. Other amendments are effective upon issuance of this ASU. This Update is not expected to have a significant impact on the Company’s financial statements. In March 2022, the FASB issued ASU 2022-01 , Derivatives and Hedging (ASC 815): Fair Value Hedging - Portfolio Layer Method In March 2022, the FASB issued ASU 2022-02, Financial Instruments - Credit Losses (ASC 326): Troubled Debt Restructurings (TDRs) and Vintage Disclosures

Summary of Lease Term and Discount Rate	The calculated amount of the ROU assets and lease liabilities in the table above are impacted by the length of the lease term and the discount rate used to present value the minimum lease payments. The Company’s lease agreements often include one or more options to renew at the Company’s discretion. If at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the ROU asset and lease liability. Regarding the discount rate, Topic 842 requires the use of the rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term. September 30, 2022 Weighted average remaining lease term Operating leases 12.2 Weighted average discount rate Operating leases 2.38 % September 30, 2021 Weighted average remaining lease term Operating leases 13.3 years Weighted average discount rate Operating leases 2.44 %
