Earnings Per Share [Abstract]
Earnings per Share	2. Earnings per Share The following table sets forth the composition of the weighted-average common shares (denominator) used in the basic and diluted earnings per share computation for the three and nine month periods ended March 31, 2022 and 2021. Three Months Ended Nine Months Ended June 30, June 30, June 30, June 30, 2022 2021 2022 2021 Weighted-average common shares outstanding 18,133,095 18,133,095 18,133,095 18,133,095 Average treasury stock shares (7,647,258 ) (7,473,715 ) (7,644,930 ) (7,362,121 ) Average unearned ESOP shares (650,628 ) (692,120 ) (661,986 ) (707,250 ) Average unearned non-vested shares (46,965 ) (61,535 ) (50,071 ) (57,683 ) Weighted average common shares and common stock equivalents used to calculate basic earnings per share 9,788,244 9,905,725 9,776,108 10,006,041 Additional common stock equivalents (nonvested stock) used to calculate diluted earnings per share 1,965 2,063 2,050 2,688 Weighted average common shares and common stock equivalents used to calculate diluted earnings per share 9,790,209 9,907,788 9,778,158 10,008,729 At June 30, 2022 there were 25,148 shares of nonvested stock outstanding at an average weighted price of $16.52 per share that were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive. At March 31, 2022 there were 23,312 shares of nonvested stock outstanding at an average weighted price of $16.15 per share that were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive.

Use of Estimates in the Preparation of Financial Statements	3. Use of Estimates in the Preparation of Financial Statements The accounting principles followed by the Company and its subsidiaries and the methods of applying these principles conform to U.S. generally accepted accounting principles (“GAAP”) and to general practice within the banking industry. In preparing the consolidated financial statements, management 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.

Accounting Changes And Error Corrections [Abstract]
Accounting Pronouncements	4. Accounting Pronouncements Adoption of New Standards In August 2018, the FASB issued ASU 2018-14, Compensation – Retirement Benefits (Topic 715-20) In January 2020, the FASB issued ASU 2020-4, 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 The adoption of ASU 2021-01 did not 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 assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019, and early adoption is permitted for annual and interim periods beginning after December 15, 2018. With certain exceptions, transition to the new requirements will be through a cumulative effect adjustment to opening retained earnings as of the beginning of the first reporting period in which the guidance is adopted. In November 2019, the FASB issued ASU 2019-10, Financial Instruments ‒ Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842) . This Update defers the effective date of ASU 2016-13 for SEC filers that are eligible to be smaller reporting companies, non-SEC filers, and all other companies to fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. We expect to recognize a one-time cumulative effect adjustment to the allowance for loan losses as of the beginning of the first reporting period in which the new standard is effective, but cannot yet determine the magnitude of any such one-time adjustment or the overall impact of the new guidance on the consolidated financial statements.

Specifically, rather than applying TDR recognition and measurement guidance, creditors will determine whether a modification results in a new loan or continuation of existing loan. These amendments are intended to enhance existing disclosure requirements and introduce new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. Additionally, the amendments to ASC 326 require that an entity disclose current-period gross writeoffs by year of origination within the vintage disclosures, which requires that an entity disclose the amortized cost basis of financing receivables by credit quality indicator and class of financing receivable by year of origination.

Loans Receivable, Net and Allowance for Loan Losses	6. Loans Receivable, Net and Allowance for Loan Losses Loans receivable consist of the following (in thousands): June 30, 2022 September 30, 2021 Real estate loans: Residential $ 597,608 $ 580,313 Construction 19,775 14,013 Commercial 649,265 591,117 Commercial 42,712 63,500 Obligations of states and political subdivisions 40,466 56,164 Home equity loans and lines of credit 41,828 38,426 Auto loans 5,296 13,852 Other 1,548 1,581 1,398,498 1,358,966 Less allowance for loan losses 18,334 18,113 Net loans $ 1,380,164 $ 1,340,853 During 2020 and 2021 the Company participated in the Paycheck Protection Program (“PPP”), administered directly by the U.S. Small Business Administration (the “SBA”). The PPP provided 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. 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 these PPP loans, the Company received approximately $2.4 million in 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 commercial loans in the above table are 16 loans totaling $2.0 million originated by the Company under the PPP through the quarter ended June 30, 2022 compared to 180 loans totaling $22.6 million at September 30, 2021. These loans mature in two or five years. Purchased loans acquired in a business combination are recorded at fair value on their purchase date without a carryover of the related allowance for loan losses. The following table presents additional information regarding loans acquired and accounted for in accordance with ASC 310-30 (in thousands): June 30, 2022 September 30, 2021 Acquired Loans with Specific Evidence or Deterioration in Credit Quality (ASC 310-30) Acquired Loans with Specific Evidence or Deterioration in Credit Quality (ASC 310-30) Outstanding balance $ 637 $ 939 Carrying amount $ 587 $ 877 The following tables show the amount of loans in each category that were 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 June 30, 2022 Real estate loans: Residential $ 597,608 $ 1,463 $ - $ 596,145 Construction 19,775 - - 19,775 Commercial 649,265 5,516 587 643,162 Commercial 42,712 77 - 42,635 Obligations of states and political subdivisions 40,466 - - 40,466 Home equity loans and lines of credit 41,828 282 - 41,546 Auto loans 5,296 7 - 5,289 Other 1,548 6 - 1,542 Total $ 1,398,498 $ 7,351 $ 587 $ 1,390,560 Total Loans Individually Evaluated for Impairment 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 sub divisions 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 that 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 we 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. 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 are classified as a troubled debt restructuring (“TDR”). A loan is considered to be a TDR loan when the Company grants a concession to the borrower that it would not otherwise consider because of the borrower’s financial condition. 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 at the time of modification may be removed from TDR status after one year of performance. The following tables include the recorded investment and unpaid principal balances for impaired loans with the associated allowance amount at the dates indicated, if applicable (in thousands): Recorded Investment Unpaid Principal Balance Associated Allowance June 30, 2022 With no specific allowance recorded: Real estate loans Residential $ 1,358 $ 2,218 $ - Construction - - - Commercial 1,707 2,279 - Commercial - 41 - Obligations of states and political subdivisions - - - Home equity loans and lines of credit 282 327 - Auto loans 7 22 - Other 6 19 - Total 3,360 4,906 - With an allowance recorded: Real estate loans Residential 105 109 13 Construction - - - Commercial 3,809 3,928 328 Commercial 77 88 41 Obligations of states and political subdivisions - - - Home equity loans and lines of credit - - - Auto loans - - - Other - - - Total 3,991 4,125 382 Total: Real estate loans Residential 1,463 2,327 13 Construction - - - Commercial 5,516 6,207 328 Commercial 77 129 41 Obligations of states and political subdivisions - - - Home equity loans and lines of credit 282 327 - Auto loans 7 22 - Other 6 19 - Total Impaired Loans $ 7,351 $ 9,031 $ 382 Recorded Investment Unpaid Principal Balance Associated Allowance September 30, 2021 With no specific allowance recorded: Real Estate Loans Residential $ 2,538 $ 3,610 $ - Construction - - - Commercial 11,152 13,030 - Commercial 165 176 - Obligations of states and political subdivisions - - - Home equity loans and lines of credit 336 368 - Auto Loans 39 60 - Other 8 21 - Total 14,238 17,265 - With an allowance recorded: Real Estate Loans Residential 108 112 17 Construction - - - Commercial 14 19 14 Commercial 1,190 1,298 397 Obligations of states and political subdivisions - - - Home equity loans and lines of credit - - - Auto Loans - - - Other - - - Total 1,312 1,429 428 Total: Real Estate Loans Residential 2,646 3,722 17 Construction - - - Commercial 11,166 13,049 14 Commercial 1,355 1,474 397 Obligations of states and political subdivisions - - - Home equity loans and lines of credit 336 368 - Auto Loans 39 60 - Other 8 21 - Total Impaired Loans $ 15,550 $ 18,694 $ 428 The following tables represents 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): For the Three Months Ended June 30, 2022 2021 2022 2021 Average Recorded Investment Average Recorded Investment Interest Income Recognized Interest Income Recognized With no specific allowance recorded: Real estate loans Residential $ 1,600 $ 1,107 $ 2 $ 2 Construction - - - - Commercial 1,722 7,422 - 6 Commercial 78 1,946 - - Obligations of states and political subdivisions - - - - Home equity loans and lines of credit 285 90 - - Auto loans 11 50 - - Other - 10 - - Total 3,696 10,625 2 8 With an allowance recorded: Real estate loans Residential 105 146 - - Construction - - - - Commercial 1,270 4,985 - - Commercial 80 4,903 - - Obligations of states and political subdivisions - - - - Home equity loans and lines of credit - - - - Auto loans - 12 - - Other - - - - Total 1,455 10,046 - - Total: Real estate loans Residential 1,705 1,253 2 2 Construction - - - - Commercial 2,992 12,407 - 6 Commercial 158 6,849 - - Obligations of states and political subdivisions - - - - Home equity loans and lines of credit 285 90 - - Auto loans 11 62 - - Other - 10 - - Total Impaired Loans $ 5,151 $ 20,671 $ 2 $ 8 For the Nine Months Ended June 30, 2022 2021 2022 2021 Average Recorded Investment Average Recorded Investment Interest Income Recognized Interest Income Recognized With no specific allowance recorded: Real estate loans Residential $ 1,935 $ 1,304 $ 7 $ 3 Construction - - - - Commercial 6,135 8,408 - 11 Commercial 88 1,569 - - Obligations of states and political subdivisions - - - - Home equity loans and lines of credit 295 98 - - Auto loans 21 52 - - Other - 11 - - Total 8,474 11,442 7 14 With an allowance recorded: Real estate loans Residential 116 171 - - Construction - - - - Commercial 431 4,908 - - Commercial 681 2,222 - - Obligations of states and political subdivisions - - - - Home equity loans and lines of credit - - - - Auto loans 4 28 - 1 Other - - - - Total 1,232 7,329 - 1 Total: Real estate loans Residential 2,051 1,475 7 3 Construction - - - - Commercial 6,566 13,316 - 11 Commercial 769 3,791 - - Obligations of states and political subdivisions - - - - Home equity loans and lines of credit 295 98 - - Auto loans 25 80 - 1 Other - 11 - - Total Impaired Loans $ 9,706 $ 18,771 $ 7 $ 15 The Company uses a ten-point internal risk-rating system to monitor the credit quality of the overall loan portfolio. 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 that are 90 or more days past due are considered Substandard. Loans in the Doubtful category have all the weaknesses inherent in loans classified as Substandard with the added characteristic that their 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. Certain residential real estate loans, construction loans, home equity loans and lines of credit, auto loans and other consumer 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 non-performing. To help ensure that risk ratings are accurate and reflect the present and future capacity of borrowers to repay a loan as agreed, the Bank 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 Bank’s commercial loan officers are responsible for the timely and accurate risk rating recommendation for the loans in their portfolios at origination and on an ongoing basis. The Bank’s commercial loan officers perform an annual review of all commercial relationships $750,000 or greater. Confirmation of the appropriate risk grade is included in the review on an ongoing basis. The Bank engages an external consultant to conduct loan reviews on at least a semi-annual basis. Generally, the external consultant reviews commercial relationships greater than $1,000,000 and/or all criticized relationships. 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 collectively evaluated for impairment are given separate consideration in the determination of the allowance.

The allowance for loan losses 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 two elements: (1) an allocated allowance, which comprises allowances established on specific loans and class allowances based on historical loss experience and current trends, and (2) an unallocated allowance based on general economic conditions and other risk factors in our markets and portfolios. 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 June 30 , 2022 was 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 and Securities, as an integral part of their examination process, have periodically reviewed our allowance for loan losses. The banking regulators may require that we recognize additions to the allowance based on its analysis and review of information available to it at the time of its 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 allowance for loan losses (“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 changes in the primary segments of the ALL for the three and nine months ended June 30, 2022 and 2021 (in thousands): Home Obligations of Equity States and Loans and Real Estate Loans Commercial Political Lines of Other Residential Construction Commercial Loans Subdivisions Credit Auto Loans Loans Unallocated Total ALL balance at March 31, 2022 $ 4,403 $ 245 $ 10,550 $ 823 $ 246 $ 310 $ 89 $ 20 $ 1,522 $ 18,208 Charge-offs (9 ) - - - - (6 ) (16 ) (11 ) - (42 ) Recoveries 130 - 15 - - 1 22 - - 168 Provision 77 14 450 (30 ) 37 36 (45 ) 11 (550 ) - ALL balance at June 30, 2022 $ 4,601 $ 259 $ 11,015 $ 793 $ 283 $ 341 $ 50 $ 20 $ 972 $ 18,334 ALL balance at March 31, 2021 $ 4,299 $ 117 $ 8,943 $ 1,770 $ 487 $ 337 $ 439 $ 20 $ 742 $ 17,154 Charge-offs (55 ) — — (200 ) — — (18 ) — — (273 ) Recoveries 149 — 20 — — 1 42 — — 212 Provision (184 ) 39 564 88 (88 ) (17 ) (120 ) — 318 600 ALL balance at June 30, 2021 $ 4,209 $ 156 $ 9,527 $ 1,658 $ 399 $ 321 $ 343 $ 20 $ 1,060 $ 17,693 ALL balance at September 30, 2021 $ 4,114 $ 187 $ 10,470 $ 1,041 $ 393 $ 318 $ 232 $ 21 $ 1,337 $ 18,113 Charge-offs (19 ) - (19 ) - - (6 ) (37 ) (11 ) - (92 ) Recoveries 202 - 22 - - 4 85 - - 313 Provision 304 72 542 (248 ) (110 ) 25 (230 ) 10 (365 ) - ALL balance at June 30, 2022 $ 4,601 $ 259 $ 11,015 $ 793 $ 283 $ 341 $ 50 $ 20 $ 972 $ 18,334 ALL balance at September 30, 2020 $ 4,301 $ 127 $ 7,209 $ 874 $ 555 $ 337 $ 780 $ 25 $ 1,192 $ 15,400 Charge-offs (59 ) — (76 ) (209 ) — (8 ) (244 ) (1 ) — (597 ) Recoveries 213 — 56 — — 4 217 — — 490 Provision (246 ) 29 2,338 993 (156 ) (12 ) (410 ) (4 ) (132 ) 2,400 ALL balance at June 30, 2021 $ 4,209 $ 156 $ 9,527 $ 1,658 $ 399 $ 321 $ 343 $ 20 $ 1,060 $ 17,693 During the three months ended June 30, 2022, the Company recorded provision expense for the residential real estate loans, construction real estate loans, commercial real estate loans, obligations of states and political subdivisions, home equity loans and lines of credit and other 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 loan loss for the commercial loans and auto loans 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 three months ended June 30, 2021, the Company recorded provision expense for the construction real estate loans, commercial real estate loans and commercial loans segments, due to either increased loan balances, changes in the loan mix within the pool, and/or charge-off activity in those segments. Provision expense was also recorded for possible loan losses due to the economic slowdown caused by COVID-19 restrictions. Credit provisions were recorded for loan loss for the residential real estate loans, obligations of states and political subdivisions, home equity loans and lines of credit and auto loans segments. During the nine months ended June 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 nine months ended June 30, 2021, the Company recorded provision expense for the construction real estate loans, commercial real estate loans and commercial loans, due to either increased loan balances, changes in the loan mix within the pool, and/or charge-off activity in those segments. Provision expense was also recorded for possible loan losses due to the economic slowdown caused by COVID-19 restrictions. Credit provisions were recorded for loan loss for the residential real estate loans, obligations of states and political subdivisions, home equity loans and lines of credit segments, auto loan and other loan segments. The Company is closely monitoring all customer credit positions, particularly loans requesting payment relief. Such loans, as of June 30, 2022, amounted to approximately 0.6% of total loans outstanding, including $8.6 million in commercial real estate loans and $368,000 in commercial loans. As the economic impact of the COVID-19 pandemic continues to evolve, our customers may experience decreased cash flows, which may correlate to an inability to make timely loan payments. This, in turn, may require increases in our allowance for loan losses and increases in the level of charge-offs in our loan portfolio. The following table summarizes the primary segments of the ALL, segregated into two categories, the amount required for loans individually evaluated for impairment and the amount required for loans collectively evaluated for impairment as of June 30, 2022 and September 30, 2021 (in thousands): Home Obligations of Equity States and Loans and Real Estate Loans Commercial Political Lines of Other Residential Construction Commercial Loans Subdivisions Credit Auto Loans Loans Unallocated Total Individually evaluated for impairment $ 13 $ - $ 328 $ 41 $ - $ - $ - $ - $ - $ 382 Collectively evaluated for impairment 4,588 259 10,687 752 283 341 50 20 972 17,952 ALL balance at June 30, 2022 $ 4,601 $ 259 $ 11,015 $ 793 $ 283 $ 341 $ 50 $ 20 $ 972 $ 18,334 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 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. Despite the above allocations, the allowance for loan losses is general in nature and is available to absorb losses from any loan segment. There were no new troubled debt restructurings granted during the three months ended June 30, 2022 and 2021. The following is a summary of troubled debt restructuring granted during the nine months ended June 30, 2022 and 2021(dollars in thousands): For the Nine Months Ended June 30, 2022 Number of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment Troubled Debt Restructurings Real estate loans: Residential 2 $ 88 $ 88 Construction — — — Commercial — — — Commercial — — — Obligations of states and political subdivisions — — — Home equity loans and lines of credit — — — Auto loans — — — Other — — — Total 2 $ 88 $ 88 For the Nine Months Ended June 30, 2021 Number of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment Troubled Debt Restructurings Real estate loans: Residential 2 $ 416 $ 416 Construction — — — Commercial 4 7,353 7,353 Commercial — — — Obligations of states and political subdivisions — — — Home equity loans and lines of credit — — — Auto loans — — — Other — — — Total 6 $ 7,769 $ 7,769 For the three and nine months ended June 30, 2022 and 2021, no loans defaulted on a restructuring agreement within one year of modification.

Equity Incentive Plan	9 . 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 that were 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 granted 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”) which was approved by shareholders on March 3, 2016. 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, ISOs and NSOs. The Company classifies share-based compensation for employees and outside directors within “Compensation and employee benefits” in the Consolidated Statement of Operations to correspond with the same line item as compensation paid. Restricted stock shares outstanding at March 31, 2022 vest over periods ranging from 6 to 42 months. 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. For the three months ended June 30, 2022 and 2021, the Company recorded $72,000 and $95,000 of share-based compensation expense, respectively, comprised of restricted stock expense. For the nine months ended June 30, 2022 and 2021, the Company recorded $427,000 and $421,000 of share-based compensation expense, respectively, comprised of restricted stock expense. Expected future compensation expense relating to the restricted shares outstanding at June 30, 2022 is $608,000 over the remaining vesting period of 3.25 years. The following is a summary of the status of the Company’s restricted stock as of June 30, 2022, and changes therein during the nine month period 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 (10,617 ) 16.40 Forfeited (7,546 ) 14.91 Nonvested at June 30, 2022 58,033 $ 14.87

Fair Value Disclosures [Abstract]
Fair Value	10. 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 and liabilities required to be measured and reported at fair value on a recurring basis on the Consolidated Balance Sheet as of June 30, 2022 and September 30, 2021 by level within the fair value hierarchy (in thousands).

Fair Value Measurement Using Significant Unobservable Inputs (Level III) Three Months Ended June 30, 2022 June 30, 2021 Beginning balance $ 10,762 $ 4,678 Purchases, sales, issuances, settlements, net 1,000 8,541 Total unrealized (loss) gain: Included in earnings - — Included in other comprehensive (loss) income (493 ) 61 Transfers in and/or out of Level III - - $ 11,269 $ 13,280 Fair Value Measurement Using Significant Unobservable Inputs (Level III) Nine Months Ended June 30, 2022 June 30, 2021 Beginning balance $ 11,112 $ 8,260 Purchases, sales, issuances, settlements, net 500 4,791 Total unrealized gain (loss): Included in earnings - — Included in other comprehensive (loss) income (843 ) 229 Transfers in and/or out of Level III 500 - $ 11,269 $ 13,280 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 June 30, 2022 and September 30, 2021 by level within the fair value hierarchy: Non-Recurring Fair Value Measurements at Reporting Date (in thousands) June 30, 2022 Level I Level II Level III Total Foreclosed real estate $ - $ - $ 75 $ 75 Impaired loans - - 6,969 6,969 September 30, 2021 Level I Level II Level III Total 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 3 Fair Value Measurements (dollars in thousands) Fair Value Estimate Valuation Techniques Unobservable Input Range (Average) June 30, 2022 Impaired loans $ 6,969 Appraisal of collateral (1) Appraisal adjustments (2) 0% to 35% (21.3%) Foreclosed real estate owned 75 Appraisal of collateral (1) Appraisal adjustments (2) 20% to 35% (28.2%) Quantitative Information about Level 3 Fair Value Measurements (dollars in thousands) Fair Value Estimate Valuation Techniques Unobservable Input Range (Average) 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. Foreclosed real estate 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 the lower of carrying amount or 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. Impaired loans are reported at fair value utilizing level three inputs. For these loans, a review of the collateral is conducted and an appropriate allowance for loan losses is allocated to the loan.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	12. Derivatives and Hedging Activities Risk Management Objective of Using Derivatives The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities and through 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 principally related to certain variable rate borrowings. 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 June 30, 2022 and September 30, 2021 (in thousands).

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 June 30, 2022, the Company had ten interest rate swaps with a notional principal amount of $225.0 million associated with the Company’s cash outflows associated with various FHLB Advances and $180.8 million associated with associated with various 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 June 30, 2022 and 2021. Amounts reported in accumulated other comprehensive income (loss) related to derivatives that will be reclassified to interest income/expense as interest payments are made/received on the Company’s variable-rate assets/liabilities. During the three months ended June 30, 2022, the Company had $222,000 of gains, which resulted in a decrease to interest expense. During the three months ended June 30, 2021, the Company had $434,000 of losses which resulted in an increase to interest expense. During the nine months ended June 30, 2022 and 2021, the Company had $180,000 and $1.7 million of losses respectively, which resulted in an increase to interest expense. During the next twelve months, the Company estimates that $5.9 million will be reclassified as a decrease to interest expense. The table below presents the effect of the Company’s cash flow hedge accounting on Accumulated Other Comprehensive Income (Loss) for the three and nine month periods ended June 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 June 30, 2022, the Company had no derivatives in a net liability position and was not required to post collateral against its obligations under these agreements. As of September 30, 2021, the Company was required to post $640,000 in collateral against its obligations under these agreements. If the Company had breached any of these provisions at June 30, 2022 and September 30, 2021, it could have been required to settle its obligations under the agreements at the termination value.

Commitments And Contingencies Disclosure [Abstract]
Contingent Liabilities	13. Contingent Liabilities 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.

Revenue From Contract With Customer [Abstract]
Revenue Recognition	14. Management determined that the primary sources of revenue associated with financial instruments, including interest income on loans and investments, along with certain noninterest revenue sources including investment security gains, loan servicing charges, gains on the sale of loans, and earnings on bank owned life insurance are not within the scope of Topic 606. Noninterest income within the scope of Topic 606 are as follows: 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.

Leases [Abstract]
Leases	15. 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. 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. With the adoption of Topic 842, operating lease agreements are required to be recognized on the Consolidated Balance sheet as a right-of-use (“ROU”) asset and a corresponding lease liability. The following table presents the Consolidated Balance Sheet classification of the Company’s ROU 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) June 30, 2022 Lease Right-of-Use Assets Classification Operating lease right-of-use assets Other assets $ 6,275 Total Lease Right-Of-Use Assets $ 6,275 (in thousands) June 30, 2022 Lease Liabilities Classification Operating lease Liabilities Other liabilities $ 6,464 Total Lease Liabilities $ 6,464 (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. For operating leases existing prior to October 1, 2019, the rate for the remaining lease term as of October 1, 2019 was used. June 30, 2022 Weighted average remaining lease term Operating leases 12.3 years Weighted average discount rate Operating leases 2.37 % 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. Lease Costs (in thousands) Three Months Ended June 30, 2022 Operating lease cost $ 238 Variable lease cost 53 Net lease cost $ 291 Lease Costs (in thousands) Three Months Ended June 30, 2021 Operating lease cost $ 264 Variable lease cost 70 Net lease cost $ 334 Lease Costs (in thousands) Nine Months Ended June 30,2022 Operating lease cost $ 739 Variable lease cost 233 Net lease cost $ 972 Lease Costs (in thousands) Nine Months Ended June 30,2021 Operating lease cost $ 791 Variable lease cost 213 Net lease cost $ 1,004 Future minimum payments for operating leases with initial or remaining terms of one year or more as of June 30, 2022 were as follows: (in thousands) Operating leases Twelve months Ended: June 30, 2023 $ 815 June 30, 2024 755 June 30, 2025 534 June 30, 2026 507 June 30, 2027 446 Thereafter 4,171 Total future minimum lease payments 7,228 Amounts representing interest 764 Present Value of Net Future Minimum Lease Payments $ 6,464

Recent Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019, and early adoption is permitted for annual and interim periods beginning after December 15, 2018. With certain exceptions, transition to the new requirements will be through a cumulative effect adjustment to opening retained earnings as of the beginning of the first reporting period in which the guidance is adopted. In November 2019, the FASB issued ASU 2019-10, Financial Instruments ‒ Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842) . This Update defers the effective date of ASU 2016-13 for SEC filers that are eligible to be smaller reporting companies, non-SEC filers, and all other companies to fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. We expect to recognize a one-time cumulative effect adjustment to the allowance for loan losses as of the beginning of the first reporting period in which the new standard is effective, but cannot yet determine the magnitude of any such one-time adjustment or the overall impact of the new guidance on the consolidated financial statements. 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 2020-3 , Codification Improvements to Financial Instruments.

Specifically, rather than applying TDR recognition and measurement guidance, creditors will determine whether a modification results in a new loan or continuation of existing loan. These amendments are intended to enhance existing disclosure requirements and introduce new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. Additionally, the amendments to ASC 326 require that an entity disclose current-period gross writeoffs by year of origination within the vintage disclosures, which requires that an entity disclose the amortized cost basis of financing receivables by credit quality indicator and class of financing receivable by year of origination. The guidance is only for entities that have adopted the amendments in Update 2016-13 for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022.

The Company is closely monitoring all customer credit positions, particularly loans requesting payment relief. Such loans, as of June 30, 2022, amounted to approximately 0.6% of total loans outstanding, including $8.6 million in commercial real estate loans and $368,000 in commercial loans. As the economic impact of the COVID-19 pandemic continues to evolve, our customers may experience decreased cash flows, which may correlate to an inability to make timely loan payments. This, in turn, may require increases in our allowance for loan losses and increases in the level of charge-offs in our loan portfolio.

Summary of Balance Sheet Operating Lease Right-of-Use Assets and Lease Liabilities	The following table presents the Consolidated Balance Sheet classification of the Company’s ROU 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) June 30, 2022 Lease Right-of-Use Assets Classification Operating lease right-of-use assets Other assets $ 6,275 Total Lease Right-Of-Use Assets $ 6,275 (in thousands) June 30, 2022 Lease Liabilities Classification Operating lease Liabilities Other liabilities $ 6,464 Total Lease Liabilities $ 6,464 (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
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. For operating leases existing prior to October 1, 2019, the rate for the remaining lease term as of October 1, 2019 was used. June 30, 2022 Weighted average remaining lease term Operating leases 12.3 years Weighted average discount rate Operating leases 2.37 %
Summary of Components of Lease Cost	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.
