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 available-for-sale securities below their cost that are deemed to be other than temporary are reflected in earnings as realized losses. In estimating other-than-temporary impairment losses, 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. 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, 2020. 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 at September 30, 2020 and 2019, were not impaired. Total servicing assets included in other assets as of September 30, 2020 and 2019, were $393,000 and $177,000, 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 3 to 7 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 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 2020 or 2019. 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 2020 and 2019. The following tables provide information for the carrying amount of goodwill and intangible assets (in thousands). Goodwill 2020 2019 Balance at beginning of year $ 13,801 $ 13,801 Goodwill acquired - - Balance at end of year $ 13,801 $ 13,801 Intangible assets 2020 2019 Balance at beginning of year $ 1,066 $ 1,375 Intangible assets acquired - - Amortization (275 ) (309 ) Balance at end of year $ 791 $ 1,066 Amortizable intangible assets were composed of the following: September 30, 2020 2019 Gross Amount Accumulated Amortization (dollars in thousands) Core deposit intangible $ 4,787 $ 3,997 $ 3,721 2020 2019 Aggregate amortization expense: As of the years ended September 30 $ 275 $ 309 Estimated future amortization expense (dollars in thousands): 2021 $ 272 2022 239 2023 190 2024 90 $ 791 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 In accordance with generally accepted accounting principles, 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 In February 2016, the FASB issued Accounting Standards Update (ASU) 2016-02, Leases. The new leases standard requires a lessor to classify leases as either sales-type, direct financing or operating, similar to existing U.S. GAAP. Classification depends on the same five criteria used by lessees plus certain additional factors. The subsequent accounting treatment for all three lease types is substantially equivalent to existing U.S. GAAP for sales-type leases, direct financing leases, and operating leases. However, the new standard updates certain aspects of the lessor accounting model to align it with the new lessee accounting model, as well as with the new revenue standard under Topic 606. Lessees and lessors are required to provide certain qualitative and quantitative disclosures to enable users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The new leases standard addresses other considerations including identification of a lease, separating lease and non-lease components of a contract, sale and leaseback transactions, modifications, combining contracts, reassessment of the lease term, and re-measurement of lease payments. It also contains comprehensive implementation guidance with practical examples ASU 2016-02 was adopted by us on October 1, 2019 and initially required transition using a modified retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. In January 2018, the FASB issued ASU 2018-01, Leases (Topic 842) “Leases (Topic 842) - Targeted Improvements,” ASU 2018-20, “Leases (Topic 842) - Narrow-Scope Improvements for Lessors,” Leases (Topic 842): Codification Improvements, Upon adoption of ASU 2016-02, ASU 2018-01, ASU 2018-11, ASU 2018-20, and ASU 2019-01 on October 1, 2019, we recognized right-of-use assets and related lease liabilities totaling $7.3 million and $7.3 million, respectively. We elected to apply certain practical expedients provided under ASU 2016-02 whereby we will not reassess (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases and (iii) initial direct costs for any existing leases. We also did not apply the recognition requirements of ASU 2016-02 to any short-term leases (as defined by related accounting guidance). We utilize d the modified-retrospective transition approach prescribed by ASU 2018-11 . Recent Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments In November 2019, the FASB issued ASU 2019-10, Financial Instruments ‒ Credit Losses (Topic 326), Derivatives and Hedging (Topic815), 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 January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment. To simplify the subsequent measurement of goodwill, the FASB eliminated Step 2 from the goodwill impairment test. In computing the implied fair value of goodwill under Step 2, an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, under the amendments in this Update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting units fa

The Company reviews its position quarterly and has asserted that at September 30, 2020 and 2019, 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, 2020 and 2019 , 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): 2020 2019 Real estate loans: Residential $ 610,380 $ 597,514 Construction 11,853 5,672 Commercial 509,628 480,647 Commercial 139,603 55,559 Obligations of states and political subdivisions 79,230 71,828 Home equity loans and lines of credit 40,800 45,156 Auto loans 39,795 81,983 Other 2,293 2,924 1,433,582 1,341,283 Less allowance for loan losses 15,400 12,630 Net loans $ 1,418,182 $ 1,328,653 During 2020 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, 2020, the Company had outstanding principal balances of $76.8 million. 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 $1.9 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. As of September 30, 2020, approximately 67 of our commercial clients had requested loan payment deferrals or payments of interest only on loans totaling $58.3 million. We have had similar request from approximately 35 mortgage customers and approximately 16 auto loan customers. Included in commercial loans in the above table are 673 loans totaling $76.8 million originated by the Company under the Payroll Protection Program during the quarter ended September 30, 2020. These loans are guaranteed by the Small Business Administration and mature in two years. Included in the September 30, 2020 balances are loans acquired from Eagle National Bank in 2015. Upon acquisition, the Company evaluated whether each acquired loan (regardless of size) was within the scope of ASC 310-30, Receivables-Loans and Debt Securities Acquired with Deteriorated Credit Quality Changes in the accretable yield for purchased credit-impaired loans were as follows, since acquisition, for the years ended September 30, 2020 and 2019 (in thousands): 2020 2019 Balance at beginning of period $ 66 $ 107 Reclassification and other - - Accretion (9 ) (41 ) Balance at end of period $ 57 $ 66 Included in reclassification and other for loans acquired without specific evidence of deterioration in credit quality were $0 and $0 of reclassifications from nonaccretable discounts to accretable discounts in 2020 and 2019 respectively. The following table presents additional information regarding loans acquired and accounted for in accordance with ASC 310-30 (in thousands): 2020 2019 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 $ 1,086 $ 1,392 Carrying amount 1,025 1,299 There has been $146,000 in allowance for loan losses recorded for acquired loans with or without specific evidence of deterioration in credit quality as of September 30, 2020. There has been $77,000 in allowance for loan losses recorded for acquired loans with or without specific evidence of deterioration in credit quality as of September 30, 2019. In addition, no allowance for loan losses has been reversed. Loans serviced by the Company for others amounted to $132,587,000 and $85,743,000 at September 30, 2020 and 2019, 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, 2020 and 2019, loans outstanding to individuals and businesses are dependent upon the local economic conditions in its immediate trade area. At September 30, 2020 and 2019, the Company had nonaccrual loans of $20,330,000 and $10,063,000, respectively. Additional interest income that would have been recorded under the original terms of the loan agreements amounted to $199,000, and $277,000 for the years ended September 30, 2020 and 2019, respectively.

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. 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. A loan is considered to be a troubled debt restructuring (“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, 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 Commercial Loan Officers perform an annual review of all commercial relationships $1,000,000 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, 2020 and 2019 (in thousands): Pass Special Mention Substandard Doubtful Total September 30, 2020 Commercial real estate loans $ 479,475 $ 15,022 $ 15,131 $ - $ 509,628 Commercial 137,860 - 1,743 - 139,603 Obligations of states and political subdivisions 79,230 - - - 79,230 Total $ 696,565 $ 15,022 $ 16,874 $ - $ 728,461 Pass Special Mention Substandard Doubtful Total September 30, 2019 Commercial real estate loans $ 461,701 $ 7,492 $ 11,454 $ - $ 480,647 Commercial 52,486 - 3,073 - 55,559 Obligations of states and political subdivisions 71,828 - - - 71,828 Total $ 586,015 $ 7,492 $ 14,527 $ - $ 608,034 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, 2020 and 2019 (in thousands): Performing Nonperforming Total September 30, 2020 Real estate loans: Residential $ 605,757 $ 4,623 $ 610,380 Construction 11,853 - 11,853 Home equity loans and lines of credit 40,581 219 40,800 Auto Loans 39,572 223 39,795 Other 2,282 11 2,293 Total $ 700,045 $ 5,076 $ 705,121 Performing Nonperforming Total September 30, 2019 Real estate loans: Residential $ 592,907 $ 4,607 $ 597,514 Construction 5,672 - 5,672 Home equity loans and lines of credit 44,534 622 45,156 Auto Loans 81,317 666 81,983 Other 2,883 41 2,924 Total $ 727,313 $ 5,936 $ 733,249 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.

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, 2019, 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, 2020 and 2019 (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, 2018 $ 3,605 $ 35 $ 3,458 $ 1,462 $ 323 $ 296 $ 1,859 $ 23 $ 627 $ 11,688 Charge-offs (330 ) - (185 ) (28 ) - (62 ) (1,233 ) (13 ) - (1,851 ) Recoveries 113 - 60 3 - 7 518 16 - 717 Provision 855 18 473 433 20 88 240 2 (53 ) 2,076 ALL balance at September 30, 2019 $ 4,243 $ 53 $ 3,806 $ 1,870 $ 343 $ 329 $ 1,384 $ 28 $ 574 $ 12,630 Individually evaluated for impairment $ 36 $ - $ 56 $ 6 $ - $ - $ 144 $ 6 $ - $ 248 Collectively evaluated for impairment 4,207 53 3,750 1,864 343 329 1,240 22 574 12,382 ALL balance at September 30, 2019 $ 4,243 $ 53 $ 3,806 $ 1,870 $ 343 $ 329 $ 1,384 $ 28 $ 574 $ 12,630 ALL balance at September 30, 2019 $ 4,243 $ 53 $ 3,806 $ 1,870 $ 343 $ 329 $ 1,384 $ 28 $ 574 $ 12,630 Charge-offs (94 ) - (122 ) - - (61 ) (786 ) (24 ) - (1,087 ) Recoveries 7 - 98 1 - 17 453 6 - 582 Provision 145 74 3,427 (997 ) 212 52 (271 ) 15 618 3,275 ALL balance at September 30, 2020 $ 4,301 $ 127 $ 7,209 $ 874 $ 555 $ 337 $ 780 $ 25 $ 1,192 $ 15,400 Individually evaluated for impairment $ 26 $ - $ 132 $ 20 $ - $ - $ 43 $ - $ - $ 221 Collectively evaluated for impairment 4,275 127 7,077 854 555 337 737 25 1,192 15,179 ALL balance at September 30, 2020 $ 4,301 $ 127 $ 7,209 $ 874 $ 555 $ 337 $ 780 $ 25 $ 1,192 $ 15,400 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, 2020 the Company recorded provision for loan losses for the residential real estate, construction loan, commercial real estate, obligations of states and political subdivisions, home equity loans and lines of credit and other 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 commercial loan and auto loan segments. During the year ended September 30, 2019 the Company recorded provision for loan losses for the residential real estate, construction loan, commercial real estate, commercial, obligations of states and political subdivisions, home equity loans and lines of credit, auto loan and other 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 not recorded for any loan segments. The provision for auto loans declined from $1.2 million to $240,000 due to declining balances offsetting net (of recoveries) charge off activity The following is a summary of troubled debt restructurings granted during the periods indicated (dollars in thousands).

Of the seven new troubled debt restructurings granted for the year ended September 30, 2019, four loans totaling $345,000 were granted term and rate concessions and two loans totaling $29,000 were granted term concessions and one loan totaling $80,000 was granted an interest rate concession. For the years ended September 30, 2020 and 2019 there was no loan modifications classified as troubled debt restructurings that subsequently defaulted within one year of modification Foreclosed assets acquired in settlement of loans are carried at fair value, less estimated costs to sell. As of September 30, 2020, the Company has initiated formal foreclosure proceedings on $1.4 million 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 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. As of September 30, 2020, over 118 of our customers had requested loan payment deferrals or payments of interest only on loans totaling $63.5 million. In accordance with Section 4013 of the CARES Act and the interagency guidance issued on April 7, 2020, these short-term deferrals are not considered troubled debt restructurings. In addition, the risk-rating on COVID-19 modified loans did not change, and these loans will not be considered past due until after the deferral period is over and scheduled payments resume. The credit quality of these loans will be reevaluated after the deferral period ends. At September 30, our non-performing assets were not materially impacted by the economic pressures of COVID-19, although there can be no assurance that our non-performing assets will not increase in the future. We continue to closely monitor credit risk and our exposure to increased loan losses resulting from the impact of COVID-19 on our commercial and consumer clients.

Accounting principles prescribe 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. 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 2016 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): 2020 2019 Amount % of Pretax Income Amount % of Pretax Income Provision at statutory rate $ 3,696 21.0 % $ 3,158 21.0 % Income from bank-owned life insurance (198 ) (1.3 ) (204 ) (1.4 ) Tax-exempt income (369 ) (2.5 ) (406 ) (2.7 ) Low-income housing credits (140 ) (0.9 ) (196 ) (1.3 ) Other, net 194 1.3 63 0.5 Actual tax expense and effective rate $ 3,183 17.6 % $ 2,415 16.1 % 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): 2020 2019 Commitments to extend credit $ 105,339 $ 80,476 Standby letters of credit 10,871 10,703 Unfunded lines of credit 98,455 106,704 The commitments outstanding at September 30, 2020, 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, 2020 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 will also seek 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. The case is currently stayed while the parties explore the possibility of a negotiated resolution to the case. In an order dated November 24, 2020, the court referred the case to Magistrate Judge Timothy J. Sullivan to assist in mediation efforts. If these discussions are not successful, the Bank will continue to defend against such 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 will 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 is now fully briefed and awaiting a decision from the court. The Bank intends to defend against such 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. On October 1, 2019, the Company adopted ASU No. 2016-02 “Leases” (Topic 842) 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, and therefore, were previously not recognized on the Company’s Consolidated Balance sheet. 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) September 30, 2020 Lease Right-of-Use Assets Classification Operating lease right-of-use assets Other assets $ 7,082 Total Lease Right-Of-Use Assets $ 7,082 (in thousands) September 30, 2020 Lease Liabilities Classification Operating lease Liabilities Other liabilities $ 7,161 Total Lease Liabilities $ 7,161 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. September 30, 2020 Weighted average remaining lease term Operating leases 14.0 Weighted average discount rate Operating leases 2.40 % 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) Twelve Months Ended September 30, 2020 Operating lease cost $ 1,049 Variable lease cost 229 Net lease cost $ 1,278 Future minimum payments for leases with initial or remaining terms of one year or more as of September 30, 2020 were as follows: (in thousands) Leases Twelve months Ended: September 30, 2021 $ 980 September 30, 2022 808 September 30, 2023 706 September 30, 2024 587 September 30, 2025 505 Thereafter 4,977 Total future minimum lease payments 8,563 Amounts representing interest (1,402 ) Present Value of Net Future Minimum Lease Payments $ 7,161

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 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 $664,000 and $700,000, for the years ended September 30, 2020 and 2019, respectively. The following table presents the components of the ESOP shares: 2020 2019 Allocated shares 374,351 348,523 Shares committed to be released 33,962 33,962 Unreleased shares 735,838 781,120 Total ESOP shares 1,144,151 1,163,605 Fair value of unreleased shares (in thousands) $ 9,073 $ 12,826 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, 2020 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, 2020 and 2019, the Company recorded $504,000 and $544,000 of share-based compensation expense consisting of restricted stock expense. Expected future compensation expense relating to the restricted shares outstanding, at September 30, 2020 is $1.1 million over the remaining vesting period of 3.08 years. The following is a summary of the status of the Company’s nonvested restricted stock as of September 30, 2020, and changes therein during the year then ended: Number of Restricted Weighted- Average Grant Date Fair Value Nonvested at September 30, 2019 34,963 $ 16.13 Granted 33,367 16.19 Vested (30,643 ) 16.21 Forfeited (2,442 ) 16.13 Nonvested at September 30, 2020 35,245 $ 16.15 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): 2020 2019 Change in benefit projected obligation: Projected benefit obligation at beginning of year $ 17,637 $ 17,111 Service cost - - Interest cost 485 693 Actuarial losses 2,670 807 Benefits paid (477 ) (974 ) Projected benefit obligation at end of year 20,315 17,637 Change in plan assets: Fair value of plan assets at beginning of year 19,395 19,720 Actual return on plan assets 1,335 649 Contributions - - Benefits paid (477 ) (974 ) Fair value of plan assets at end of year 20,253 19,395 Funded status $ (62 ) $ 1,758 Amounts not yet recognized as a component of net periodic pension cost (in thousands): 2020 2019 Amounts recognized in accumulated other comprehensive loss consist of: Net loss $ 4,344 $ 1,933 The accumulated benefit obligation for the defined benefit pension plan was $20,315,000 and $17,637,000 at September 30, 2020 and 2019, respectively. The following table comprises the components of net periodic benefit cost for the years ended September 30 (in thousands): 2020 2019 Service cost $ - $ - Interest cost 485 693 Expected return on plan assets (1,076 ) (1,171 ) Net periodic (benefit) cost $ (591 ) $ (478 ) Weighted-average assumptions used to determine benefit obligations: 2020 2019 Discount rate 2.33 % 3.00 % Rate of compensation increase N/A N/A Weighted-average assumptions used to determine net periodic benefit cost for the years ended: 2020 2019 Discount rate 3.00 % 4.10 % Expected long-term return on plan assets 6.00 % 6.00 % Rate of compensation increase N/A N/A The expected long-term rate of return was estimated using market benchmarks by which the plan assets would outperform the market in the future, based on historical experience adjusted for changes in asset allocation and expectations for overall lower future returns on similar investments compared with past periods. Plan Assets The following tables set forth by level, within the fair value hierarchy, the plan’s financial assets at fair value as of September 30, 2020 and 2019 (in thousands): September 30, 2020 Level I Level II Level III Total Investment in collective trusts: Fixed income $ - $ 8,047 $ - $ 8,047 Equity - 11,900 - 11,900 Investment in short-term investments - 306 - 306 Total assets at fair value $ - $ 20,253 $ - $ 20,253 September 30, 2019 Level I Level II Level III Total Investment in collective trusts: Fixed income $ - $ 7,736 $ - $ 7,736 Equity - 11,620 - 11,620 Investment in short-term investments - 39 - 39 Total assets at fair value $ - $ 19,395 $ - $ 19,395 Investments in collective trusts and short-term investments are valued at the net asset value of shares held by the plan. The Bank’s defined benefit pension plan weighted-average asset allocations at September 30, 2020 and 2019 by asset category, are as follows: September 30, Asset Category 2020 2019 Fixed income securities 39.7 % 39.9 % Equity securities 58.8 59.9 Other 1.5 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 2021. Estimated future benefit payments, which reflect expected future service, as appropriate, are as follows (in thousands): 2021 $ 1,838 2022 626 2023 815 2024 689 2025 1,574 2026-2030 4,859 401(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, 2020 and 2019 was $473,000 and $449,000, 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 $2.3 million and $2.2 million at September 30, 2020 and 2019, respectively which represent the estimated present value (using a discount rate of 6.00 percent) of the benefits earned under this agreement. There was $53,000 and $114,000 in expense related to the supplemental executive retirement plan for the years ended September 30, 2020 and 2019, 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. The required reserve at September 30, 2020 and 2019, was $0 and $21,390,000, respectively. In response to the pandemic, the Federal Reserve Bank reduced the reserve requirement to zero effective March 26, 2020. 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

Regulatory Capital Requirements	12 Months Ended

Banking And Thrift Other Disclosures [Abstract]
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 and the Company are 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. 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, 2020, the Bank met all capital adequacy requirements to which it is subject. In July of 2013 the respective U.S. federal banking agencies issued final rules implementing Basel III and the Dodd-Frank Act capital requirements to be fully-phased in on a global basis on January 1, 2019. The new regulations established a new tangible common equity capital requirement, increase the minimum requirement for the current Tier 1 risk-weighted asset (“RWA”) ratio, phase out certain kinds of tangibles treated as capital and certain types of instruments and change the risk weightings of certain assets used to determine requirement capital ratios. Provisions of the Dodd-Frank Act generally require these capital rules to apply to bank holding companies and their subsidiaries. The new common equity Tier 1 capital component requires capital of the highest quality-predominantly composed of retained earnings and common stock instruments. For community banks, such as ESSA Bank & Trust, a common equity Tier 1 capital ratio of 4.5% became effective on January 1, 2015. The new capital rules also increased the current minimum of Tier 1 capital ratio from 4.0% to 6.0% beginning on January 1, 2015. In addition, in order to make capital distributions and pay discretionary bonuses to executive officers without restriction, an institution must also maintain greater than 2.5% in common equity attributable to a capital conservation buffer to be phased in from January 1, 2016 until January 1, 2019. The new rules also increase the risk weights for several categories of assets, including an increase from 100% to 150% for certain acquisition, development and construction loans and more than 90-day past due exposures. The new capital rules maintain the general structure of the prompt corrective action rules, but incorporate the new common equity Tier 1 capital requirement and the increased Tier 1 RWA requirement into the prompt corrective action framework. 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. As of September 30, 2020, and 2019, 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 are presented in the following table (dollars in thousands): 2020 2019 Amount Ratio Amount Ratio Total capital (to risk-weighted assets) Actual $ 192,423 13.7 % $ 184,214 14.0 % For capital adequacy purposes 112,039 8.0 105,281 8.0 To be well capitalized 140,049 10.0 131,602 10.0 Tier 1 capital (to risk-weighted assets) Actual $ 176,971 12.6 % $ 171,532 13.0 % For capital adequacy purposes 84,029 6.0 78,961 6.0 To be well capitalized 112,039 8.0 105,281 8.0 Common equity tier 1 capital (to risk-weighted assets) Actual $ 176,971 12.6 % $ 171,532 13.0 % For capital adequacy purposes 63,022 4.5 59,221 4.5 To be well capitalized 91,032 6.5 85,541 6.5 Tier 1 capital (to adjusted assets) Actual $ 176,971 9.1 % $ 171,532 9.7 % For capital adequacy purposes 77,919 4.0 70,979 4.0 To be well capitalized 97,399 5.0 88,724 5.0 The Company’s ratios do not differ significantly from the Bank’s ratios presented above.

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, 2020 and September 30, 2019 by level within the fair value hierarchy (in thousands).

Fair Value Measurement Using Significant Unobservable Inputs (Level III) September 30, 2020 September 30, 2019 Beginning balance $ 7,792 $ 7,738 Purchases, sales, issuances, settlements, net 500 - Total unrealized gain: Included in earnings - - Included in other comprehensive income (32 ) 54 Transfers into Level III - - Transfers out of Level III - - $ 8,260 $ 7,792 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, 2020 and September 30, 2019 by level within the fair value hierarchy: 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, 2020 Impaired loans $ 16,983 Appraisal of collateral (1) Appraisal adjustments (2) 0% to 35% (20.5%) Foreclosed real estate owned 269 Appraisal of collateral (1) Appraisal adjustments (2) 20% to 35% (25.7%) September 30, 2019 Impaired loans $ 8,128 Appraisal of collateral (1) Appraisal adjustments (2) 0% to 35% (20.3%) Foreclosed real estate owned 240 Appraisal of collateral (1) Appraisal adjustments (2) 20% to 35% (26.6%) (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. At September 30, 2020, 111 impaired loans with a carrying value of $17.2 million were reduced by specific valuation allowance totaling $221,000 resulting in a net fair value of $17.0 million based on Level 3 inputs. At September 30, 2019, 138 impaired loans with a carrying value of $8.4 million were reduced by a specific valuation totaling $248,000 resulting in a net fair value of $8.1 million based on Level 3 inputs. 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 $17.2 million less their valuation allowances of $221,000 at September 30, 2020. The fair value consists of the loan balances of $8.4 million less their valuation allowances of $248,000 at September 30, 2019. 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, 2020 is in accordance with ASC Topic 825, Financial Instruments September 30, 2020 Carrying Value Level I Level II Level III Total Fair Value Financial assets: Loans receivable, net 1,418,182 - - 1,426,962 1,426,962 Mortgage servicing rights 393 - - 393 393 Financial liabilities: Deposits $ 1,543,695 $ 1,080,201 $ - $ 467,630 $ 1,547,831 Other borrowings 14,164 - - 14,395 14,395 September 30, 2019 Carrying Value Level I Level II Level III Total Fair Value Financial assets: Loans receivable, net 1,328,653 - - 1,313,231 1,313,231 Mortgage servicing rights 177 - - 241 241 Deposits $ 1,342,830 $ 900,252 $ - $ 443,063 $ 1,343,315 Other borrowings 140,581 - - 141,427 141,427 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. The fair value approximates the current book value.

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, 2020 and 2019, (in thousands). Fair Values of Derivative Instruments Asset Derivatives As of September 30, 2020 As of September 30, 2019 Hedged Item Notional Amount Balance Sheet Location Fair Value Notional Amount Balance Sheet Location Fair Value FHLB Advances $ - $ - $ 50,000 Other Assets $ 303 Commercial Loans 55,784 Other Assets 2,192 - - Total derivatives designated as hedging instruments $ 55,784 $ 2,192 $ 50,000 $ 303 Fair Values of Derivative Instruments Liability Derivatives As of September 30, 2020 As of September 30, 2019 Hedged Item Notional Amount Balance Sheet Location Fair Value Balance Sheet Location Fair Value Brokered Deposits $ 25,000 Other Liabilities $ 700 $ 50,000 $ - FHLB Advances 410,000 Other Liabilities 4,098 35,000 Other Liabilities 1,011 Commercial Loans 70,784 Other Liabilities 2,204 - - Total derivatives designated as hedging instruments $ 505,784 $ 7,002 $ 85,000 $ 1,011 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, 2020, the Company had nineteen interest rate swaps with a notional of $435 million associated with the Company’s cash outflows associated with various FHLB advances and brokered deposits and $71 million associated with commercial loans. As of September 30, 2019, the Company had seven interest rate swaps with a notional of $135 million associated with the company’s cash outflows associated with various FHLB advances. 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, 2020 and 2019. 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, 2020 and 2019, the Company had $554,000 in losses and $934,000 in gains classified to interest expense, respectively. During the next twelve months, the Company estimates that $2.3 million 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, 2020 and 2019 (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, 2020 and 2019 the Company had derivatives in a net liability position and was required to post $7.5 million and $710,000 in collateral against its obligations under these agreements. If the Company had breached any of these provisions at September 30, 2020 and 2019, 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 Management determined that since the guidance does not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other GAAP, the new guidance did not have a material impact on revenue most closely associated with financial instruments including interest income and expense along with non interest revenue resulting from non interest security gains, loan servicing, commitment fees and fees from financial guarantees. As a result, no changes were made during the period related to these sources of revenue which cumulatively comprise 90.3% of the total revenue of the Company. 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.

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 available-for-sale securities below their cost that are deemed to be other than temporary are reflected in earnings as realized losses. In estimating other-than-temporary impairment losses, 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.
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, 2020.
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 at September 30, 2020 and 2019, were not impaired. Total servicing assets included in other assets as of September 30, 2020 and 2019, were $393,000 and $177,000, 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 3 to 7 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 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 2020 or 2019. 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 2020 and 2019. The following tables provide information for the carrying amount of goodwill and intangible assets (in thousands). Goodwill 2020 2019 Balance at beginning of year $ 13,801 $ 13,801 Goodwill acquired - - Balance at end of year $ 13,801 $ 13,801 Intangible assets 2020 2019 Balance at beginning of year $ 1,066 $ 1,375 Intangible assets acquired - - Amortization (275 ) (309 ) Balance at end of year $ 791 $ 1,066 Amortizable intangible assets were composed of the following: September 30, 2020 2019 Gross Amount Accumulated Amortization (dollars in thousands) Core deposit intangible $ 4,787 $ 3,997 $ 3,721 2020 2019 Aggregate amortization expense: As of the years ended September 30 $ 275 $ 309 Estimated future amortization expense (dollars in thousands): 2021 $ 272 2022 239 2023 190 2024 90 $ 791
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 In accordance with generally accepted accounting principles, 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	Adoption of New Standards In February 2016, the FASB issued Accounting Standards Update (ASU) 2016-02, Leases. The new leases standard requires a lessor to classify leases as either sales-type, direct financing or operating, similar to existing U.S. GAAP. Classification depends on the same five criteria used by lessees plus certain additional factors. The subsequent accounting treatment for all three lease types is substantially equivalent to existing U.S. GAAP for sales-type leases, direct financing leases, and operating leases. However, the new standard updates certain aspects of the lessor accounting model to align it with the new lessee accounting model, as well as with the new revenue standard under Topic 606. Lessees and lessors are required to provide certain qualitative and quantitative disclosures to enable users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The new leases standard addresses other considerations including identification of a lease, separating lease and non-lease components of a contract, sale and leaseback transactions, modifications, combining contracts, reassessment of the lease term, and re-measurement of lease payments. It also contains comprehensive implementation guidance with practical examples ASU 2016-02 was adopted by us on October 1, 2019 and initially required transition using a modified retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. In January 2018, the FASB issued ASU 2018-01, Leases (Topic 842) “Leases (Topic 842) - Targeted Improvements,” ASU 2018-20, “Leases (Topic 842) - Narrow-Scope Improvements for Lessors,” Leases (Topic 842): Codification Improvements, Upon adoption of ASU 2016-02, ASU 2018-01, ASU 2018-11, ASU 2018-20, and ASU 2019-01 on October 1, 2019, we recognized right-of-use assets and related lease liabilities totaling $7.3 million and $7.3 million, respectively. We elected to apply certain practical expedients provided under ASU 2016-02 whereby we will not reassess (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases and (iii) initial direct costs for any existing leases. We also did not apply the recognition requirements of ASU 2016-02 to any short-term leases (as defined by related accounting guidance). We utilize d the modified-retrospective transition approach prescribed by ASU 2018-11 .
Recent Accounting Pronouncements	Recent Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments In November 2019, the FASB issued ASU 2019-10, Financial Instruments ‒ Credit Losses (Topic 326), Derivatives and Hedging (Topic815), 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 January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment. To simplify the subsequent measurement of goodwill, the FASB eliminated Step 2 from the goodwill impairment test. In computing the implied fair value of goodwill under Step 2, an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, under the amendments in this Update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting units fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. A public business entity that is a U.S. Securities and Exchange Commission (SEC) filer should adopt the amendments in this Update for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. A public business entity that is not an SEC filer should adopt the amendments in this Update for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2020. All other entities, including not-for-profit entities, that are adopting the amendments in this Update should do so for their annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2021. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes the Disclosure Requirements for Fair Value Measurements. The Update removes the requirement to disclose the amount of and reasons for transfers between Level I and Level II of the fair value hierarchy; the policy for timing of transfers between levels; and the valuation processes for Level III fair value measurements. The Update requires disclosure of changes in unrealized gains and losses for the period included in other comprehensive income (loss) for recurring Level III fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level III fair value measurements. This Update is effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. This Update is not expected to have a significant impact on the Company’s financial statements. In August 2018, the FASB issued ASU 2018-14, Compensation – Retirement Benefits (Topic 715-20) In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments – Credit Losses, Topic 815, Derivatives and Hedging Financial Instruments Financial Instruments – Credit Losses Topic 815, Derivatives and Hedging In May 2019, the FASB issued ASU 2019-05, Financial Instruments – Credit Losses, Topic 326 In November 2019, the FASB issued ASU 2019-10, Financial Instruments ‒ Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842) Intangibles ‒ Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (Goodwill) In November 2019, the FASB issued ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments – Credit Losses In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740 In January 2020, the FASB issued ASU 2020-01, Investments – Equity Securities (Topic 321) Investments – Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. The amendments also clarify that, for the purpose of applying paragraph 815-10-15-141(a) an entity should not consider whether, upon the settlement of the forward contract or exercise of the purchased option, individually or with existing investments, the underlying securities would be accounted for under the equity method in Topic 323 or the fair value option, in accordance with the financial instruments guidance in Topic 825. An entity also would evaluate the remaining characteristics in paragraph 815-10-15-141 to determine the accounting for those forward contracts and purchased options. For public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. This Update is not expected to have a significant impact on the Company’s financial statements. In January 2020, the FASB issued ASU 2020-02, Financial Instruments – Credit Losses (Topic 326) and Leases (Topic 842): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 119 and Update to SEC Section on Effective Date Related to Accounting Standards Update No. 2016-02, Leases (Topic 842), February 2020 In March 2020, the FASB issued ASU 2020-03 , Codification Improvements to Financial Instruments. Financial Instruments 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 August 2020, the FASB issued ASU 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40)

Leases [Abstract]
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) September 30, 2020 Lease Right-of-Use Assets Classification Operating lease right-of-use assets Other assets $ 7,082 Total Lease Right-Of-Use Assets $ 7,082 (in thousands) September 30, 2020 Lease Liabilities Classification Operating lease Liabilities Other liabilities $ 7,161 Total Lease Liabilities $ 7,161
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. September 30, 2020 Weighted average remaining lease term Operating leases 14.0 Weighted average discount rate Operating leases 2.40 %
