Use of Estimates in the Preparation of Financial Statements	3. Use of Estimates in the Preparation of Financial Statements The accounting principles followed by the Company and its subsidiaries and the methods of applying these principles conform to U.S. generally accepted accounting principles (“GAAP”) and to general practice within the banking industry. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the Consolidated Balance Sheet date and related revenues and expenses for the period. Actual results could differ from those estimates.

Accounting Changes And Error Corrections [Abstract]
Accounting Pronouncements	4. Accounting Pronouncements Adoption of New Standards In 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 utilized 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 Financial Instruments ‒ Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842) In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment In July 2017, the FASB issued ASU 2017-11 , Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), and Derivative and Hedging (Topic 815) Subtopic 470-20, Debt ‒ Debt with Conversion and Other Options In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes the Disclosure Requirements for Fair Value Measurements 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 May 2019, the FASB issued ASU 2019-06, Intangibles – Goodwill and Other (Topic 350), Business Combinations (Topic 805), and Not-for-Profit Entities (Topic 958): Extending the Private Company Accounting Alternatives on Goodwill and Certain Identifiable Intangible Assets to Not-for-Profit Entities 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 2020-1, Investments – Equity Securities (Topic 321)

Such system takes into consideration, among other things, delinquency status, size of loans, type and market value of collateral and financial condition of the borrowers. Specific loan loss allowances are established for identified losses based on a review of such information. A loan evaluated for impairment is considered to be impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement. All loans identified as impaired are evaluated independently. The Company does not aggregate such loans for evaluation purposes. Impairment is measured on a loan-by-loan basis for commercial and construction loans by the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral-dependent. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer and residential mortgage loans for impairment disclosures, unless such loans are part of a larger relationship that is impaired, or are classified as a troubled debt restructuring. 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 at the dates indicated, if applicable (in thousands): Recorded Investment Unpaid Principal Balance Associated Allowance December 31, 2019 With no specific allowance recorded: Real estate loans Residential $ 3,975 $ 5,432 $ — Construction — — — Commercial 2,272 4,193 — Commercial 432 471 — Obligations of states and political subdivisions — — — Home equity loans and lines of credit 304 331 — Auto loans 119 233 — Other 14 23 — Total 7,116 10,683 — With an allowance recorded: Real estate loans Residential 201 226 31 Construction — — — Commercial 179 215 55 Commercial — — — Obligations of states and political subdivisions — — — Home equity loans and lines of credit — — — Auto loans 245 276 116 Other 15 16 8 Total 640 733 210 Total: Real estate loans Residential 4,176 5,658 31 Construction — — — Commercial 2,451 4,408 55 Commercial 432 471 — Obligations of states and political subdivisions — — — Home equity loans and lines of credit 304 331 — Auto loans 364 509 116 Other 29 39 8 Total Impaired Loans $ 7,756 $ 11,416 $ 210 Recorded Investment Unpaid Principal Balance Associated Allowance September 30, 2019 With no specific allowance recorded: Real Estate Loans Residential $ 3,935 $ 5,309 $ — Construction — — — Commercial 2,385 4,269 — Commercial 354 475 — Obligations of states and political subdivisions — — — Home equity loans and lines of credit 400 465 — Auto Loans 161 248 — Other 15 22 — Total 7,250 10,788 — With an allowance recorded: Real Estate Loans Residential 346 398 36 Construction — — — Commercial 248 294 56 Commercial 94 223 6 Obligations of states and political subdivisions — — — Home equity loans and lines of credit — — — Auto Loans 422 426 144 Other 16 17 6 Total 1,126 1,358 248 Total: Real Estate Loans Residential 4,281 5,707 36 Construction — — — Commercial 2,633 4,563 56 Commercial 448 698 6 Obligations of states and political subdivisions — — — Home equity loans and lines of credit 400 465 — Auto Loans 583 674 144 Other 31 39 6 Total Impaired Loans $ 8,376 $ 12,146 $ 248 The following table represents the average recorded investments in the impaired loans and the related amount of interest recognized during the time within the period that the impaired loans were impaired (in thousands): For the Three Months Ended December 31, 2019 2018 2019 2018 Average Recorded Investment Average Recorded Investment Interest Income Recognized Interest Income Recognized With no specific allowance recorded: Real estate loans Residential $ 3,933 $ 4,167 $ 1 $ 3 Construction — — — — Commercial 2,398 4,484 — 45 Commercial 392 84 — — Obligations of states and political subdivisions — — — — Home equity loans and lines of credit 322 151 — — Auto loans 116 87 1 1 Other 19 17 — — Total 7,180 8,990 2 49 With an allowance recorded: Real estate loans Residential 297 815 — — Construction — — — — Commercial 333 — — — Commercial 65 — — — Obligations of states and political subdivisions — — — — Home equity loans and lines of credit — 13 — — Auto loans 212 204 — — Other 5 — — — Total 912 1,032 — — Total: Real estate loans Residential 4,230 4,982 1 3 Construction — — — — Commercial 2,731 4,484 — 45 Commercial 457 84 — — Obligations of states and political subdivisions — — — — Home equity loans and lines of credit 322 164 — — Auto loans 328 291 1 1 Other 24 17 — — Total Impaired Loans $ 8,092 $ 10,022 $ 2 $ 49 The Company uses a ten-point internal risk-rating system to monitor the credit quality of the overall loan portfolio. The first six categories are considered not criticized and are aggregated as Pass-rated. The criticized rating categories utilized by management generally follow bank regulatory definitions. The Special Mention category includes assets that are fundamentally sound yet exhibit potentially unacceptable credit risk or deteriorating trends or characteristics which, if left uncorrected, may result in deterioration of the repayment prospects for the asset or in the Company’s credit position at some future date. Loans in the Substandard category have well-defined weaknesses that jeopardize the liquidation of the debt and have a distinct possibility that some loss will be sustained if the weaknesses are not corrected. All loans that are 90 or more days past due are considered Substandard. Loans in the Doubtful category have all the weaknesses inherent in loans classified as Substandard with the added characteristic that their weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loans in the Loss category are considered uncollectible and of little value that their continuance as bankable assets is not warranted. Certain residential real estate loans, construction loans, home equity loans and lines of credit, auto loans and other consumer loans are underwritten and structured using standardized criteria and characteristics, primarily payment performance, and are normally risk rated and monitored collectively on a monthly basis. These are typically loans to individuals in the consumer categories and are delineated as either performing or non-performing. To help ensure that risk ratings are accurate and reflect the present and future capacity of borrowers to repay a loan as agreed, the Bank has a structured loan rating process with several layers of internal and external oversight. Generally, consumer and residential mortgage loans are included in the Pass categories unless a specific action, such as bankruptcy, repossession, or death occurs to raise awareness of a possible credit event. The Bank’s commercial loan officers are responsible for the timely and accurate risk rating recommendation for the loans in their portfolios at origination and on an ongoing basis. The Bank’s commercial loan officers perform an annual review of all commercial relationships $750,000 or greater. Confirmation of the appropriate risk grade is included in the review on an ongoing basis. The Bank engages an external consultant to conduct loan reviews on at least a semi-annual basis. Generally, the external consultant reviews commercial relationships greater than $1,000,000 and/or all criticized relationships. Detailed reviews, including plans for resolution, are performed on loans classified as Substandard on a quarterly basis. Loans in the Special Mention and Substandard categories that are collectively evaluated for impairment are given separate consideration in the determination of the allowance. The following tables present the classes of the loan portfolio summarized by the aggregate Pass and the criticized categories of Special Mention, Substandard, and Doubtful or Loss within the internal risk rating system at December 31, 2019 and September 30, 2019 (in thousands): Pass Special Mention Substandard Doubtful or Loss Total December 31, 2019 Commercial real estate loans $ 465,560 $ 10,180 $ 7,780 $ — $ 483,520 Commercial 68,505 2,751 — 71,256 Obligations of states and political subdivisions 75,932 — — — 75,932 Total $ 609,997 $ 10,180 $ 10,531 $ — $ 630,708 Pass Special Mention Substandard Doubtful or Loss 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 non-performing.

Management, in determining the allowance for loan losses, considers the losses inherent in its loan portfolio and changes in the nature and volume of loan activities, along with the general economic and real estate market conditions. The allowance for loan losses consists of two elements: (1) an allocated allowance, which comprises allowances established on specific loans and class allowances based on historical loss experience and current trends, and (2) an allocated allowance based on general economic conditions and other risk factors in our markets and portfolios. We maintain a loan review system, which allows for a periodic review of our loan portfolio and the early identification of potential impaired loans. Such system takes into consideration, among other things, delinquency status, size of loans, type and market value of collateral and financial condition of the borrowers. General loan loss allowances are based upon a combination of factors including, but not limited to, actual loan loss experience, composition of the loan portfolio, current economic conditions, management’s judgment and losses which are probable and reasonably estimable. The allowance is increased through provisions charged against current earnings and recoveries of previously charged-off loans. Loans that are determined to be uncollectible are charged against the allowance. While management uses available information to recognize probable and reasonably estimable loan losses, future loss provisions may be necessary, based on changing economic conditions. Payments received on impaired loans generally are either applied against principal or reported as interest income, according to management’s judgment as to the collectability of principal. The allowance for loan losses as of December 31, 2019 was maintained at a level that represents management’s best estimate of losses inherent in the loan portfolio, and such losses were both probable and reasonably estimable. In addition, the FDIC and the Pennsylvania Department of Banking and Securities, as an integral part of their examination process, have periodically reviewed our allowance for loan losses. The banking regulators may require that we recognize additions to the allowance based on its analysis and review of information available to it at the time of its examination. Management reviews the loan portfolio on a quarterly basis using a defined, consistently applied process in order to make appropriate and timely adjustments to the allowance for loan losses (“ALL”). When information confirms all or part of specific loans to be uncollectible, these amounts are promptly charged off against the ALL. The following table summarizes changes in the primary segments of the ALL for the three months ended December 31, 2019 and 2018 (in thousands): Home Obligations of Equity States and Loans and Real Estate Loans Commercial Political Lines of Other Residential Construction Commercial Loans Subdivisions Credit Auto Loans Loans Unallocated Total ALL balance at September 30, 2019 $ 4,243 $ 53 $ 3,806 $ 1,870 $ 343 $ 329 $ 1,384 $ 28 $ 574 $ 12,630 Charge-offs (22 ) — (40 ) — — (29 ) (372 ) (2 ) — (465 ) Recoveries 1 — 42 1 — 1 161 1 — 207 Provision (61 ) 29 (204 ) 370 (3 ) 68 59 (3 ) 120 375 ALL balance at December 31, 2019 $ 4,161 $ 82 $ 3,604 $ 2,241 $ 340 $ 369 $ 1,232 $ 24 $ 694 $ 12,747 ALL balance at September 30, 2018 $ 3,605 $ 35 $ 3,458 $ 1,462 $ 323 $ 296 $ 1,859 $ 23 $ 627 $ 11,688 Charge-offs (142 ) — — (22 ) — — (368 ) — — (532 ) Recoveries 6 — — — — 1 181 1 — 189 Provision 276 8 38 264 (28 ) 1 22 2 293 876 ALL balance at December 31, 2018 $ 3,745 $ 43 $ 3,496 $ 1,704 $ 295 $ 298 $ 1,694 $ 26 $ 920 $ 12,221 During the three months ended December 31, 2019 the Company recorded provision expense for the construction real estate loans, commercial, home equity loans and lines of credit and auto loan segments, due to either increased loan balances, changes in the loan mix within the pool, and/or charge-off activity in those segments. Credit provisions were recorded for loan loss for the residential real estate, commercial real estate, obligations of states and political subdivisions and other loan segments. During the three months ended December 31, 2018 the Company recorded provision expense for the residential real estate, construction loans, commercial real estate, commercial, home equity loans and lines of credit, auto and other loan segments, due to either increased loan balances, changes in the loan mix within the pool, and/or charge-off activity in those segments. Credit provisions were recorded for loan loss for the obligations of states and political subdivisions segment. The following table summarizes the primary segments of the ALL, segregated into two categories, the amount required for loans individually evaluated for impairment and the amount required for loans collectively evaluated for impairment as of December 31, 2019 and September 30, 2019 (in thousands): Home Obligations of Equity States and Loans and Real Estate Loans Commercial Political Lines of Other Residential Construction Commercial Loans Subdivisions Credit Auto Loans Loans Unallocated Total Individually evaluated for impairment $ 31 $ — $ 55 $ — $ — $ — $ 116 $ 8 $ — $ 210 Collectively evaluated for impairment 4,130 82 3,549 2,241 340 369 1,116 16 694 12,537 ALL balance at December 31, 2019 $ 4,161 $ 82 $ 3,604 $ 2,241 $ 340 $ 369 $ 1,232 $ 24 $ 694 $ 12,747 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 The allowance for loan losses is based on estimates, and actual losses will vary from current estimates. Management believes that the granularity of the homogeneous pools and the related historical loss ratios and other qualitative factors, as well as the consistency in the application of assumptions, result in an ALL that is representative of the risk found in the components of the portfolio at any given date. Despite the above allocations, the allowance for loan losses is general in nature and is available to absorb losses from any loan segment. The following is a summary of troubled debt restructuring granted during the three months ended December 31, 2019 and 2018 (dollars in thousands): For the Three Months Ended December 31, 2019 Number of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment Troubled Debt Restructurings Real estate loans: Residential 1 $ 540 $ 540 Construction — — — Commercial — — — Commercial — — — Obligations of states and political subdivisions — — — Home equity loans and lines of credit — — — Auto loans — — — Other — — — Total 1 $ 540 $ 540 For the Three Months Ended December 31, 2018 Number of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment Troubled Debt Restructurings Real estate loans: Residential 2 $ 95 $ 95 Construction — — — Commercial — — — Commercial — — — Obligations of states and political subdivisions — — — Home equity loans and lines of credit 2 159 159 Auto loans 1 21 21 Other — — — Total 5 $ 275 $ 275 The one new troubled debt restructuring granted for the three months ended December 31, 2019, totaled $540,000 and was granted an interest rate concession.

Equity Incentive Plan	9 . Equity Incentive Plan The Company previously maintained the ESSA Bancorp, Inc. 2007 Equity Incentive Plan (the “Plan”). The Plan provided for a total of 2,377,326 shares of common stock for issuance upon the grant or exercise of awards. Of the shares that were available under the Plan, 1,698,090 were available to be issued in connection with the exercise of stock options and 679,236 were available to be issued as restricted stock. The Plan allowed for the granting of non-qualified stock options (“NSOs”), incentive stock options (“ISOs”), and restricted stock. Options granted under the plan were granted at no less than the fair value of the Company’s common stock on the date of the grant. As of the effective date of the 2016 Equity Incentive Plan (detailed below), no further grants will be made under the Plan and forfeitures of outstanding awards under the Plan will be added to the shares available under the 2016 Equity Incentive Plan. The Company replaced the 2007 Equity Incentive Plan with the ESSA Bancorp, Inc. 2016 Equity Incentive Plan (the “2016 Plan”) which was approved by shareholders on March 3, 2016. The 2016 Plan provides for a total of 250,000 shares of common stock for issuance upon the grant or exercise of awards. The 2016 Plan allows for the granting of restricted stock, restricted stock units, ISOs and NSOs. The Company classifies share-based compensation for employees and outside directors within “Compensation and employee benefits” in the Consolidated Statement of Operations to correspond with the same line item as compensation paid. Restricted stock shares outstanding at December 31, 2019 vest over periods ranging from 8 to 45 months. The product of the number of shares granted and the grant date market price of the Company’s common stock determines the fair value of restricted shares under the Company’s restricted stock plan. The Company expenses the fair value of all share based compensation grants over the requisite service period. For the three months ended December 31, 2019 and 2018, the Company recorded $240,000 and $252,000 of share-based compensation expense, respectively, comprised of restricted stock expense. Expected future compensation expense relating to the restricted shares outstanding at December 31, 2019 is $865,000 over the remaining vesting period of 3.75 years. The following is a summary of the status of the Company’s restricted stock as of December 31, 2019, and changes therein during the three month period 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 (819 ) 15.52 Forfeited — — Nonvested at December 31, 2019 67,511 $ 16.17

Fair Value Disclosures [Abstract]
Fair Value	10. Fair Value The following disclosures show the hierarchal disclosure framework associated within the level of pricing observations utilized in measuring assets and liabilities at fair value. The definition of fair value maintains the exchange price notion in earlier definitions of fair value but focuses on the exit price of the asset or liability. The exit price is the price that would be received to sell the asset or paid to transfer the liability adjusted for certain inherent risks and restrictions. Expanded disclosures are also required about the use of fair value to measure assets and liabilities. Assets and Liabilities Required to be Measured and Reported at Fair Value on a Recurring Basis The following tables provide the fair value for assets and liabilties required to be measured and reported at fair value on a recurring basis on the Consolidated Balance Sheet as of December 31, 2019 and September 30, 2019 by level within the fair value hierarchy (in thousands). Recurring Fair Value Measurements at Reporting Date December 31, 2019 Assets Level I Level II Level III Total Investment securities available for sale: Mortgage backed securities $ — $ 216,148 $ — $ 216,148 Obligations of states and political subdivisions — 22,614 — 22,614 U.S. government agencies — 14,580 — 14,580 Corporate obligations — 35,852 7,821 43,673 Other debt securities — 15,753 — 15,753 Total Debt Securities $ — $ 304,947 $ 7,821 $ 312,768 Equity securities- financial services 26 — — 26 Derivatives and hedging activities: — 273 — 273 Liabilities Derivatives and hedging activities: — 846 — 846 September 30, 2019 Level I Level II Level III Total Investment securities available for sale: Mortgage backed securities $ — $ 226,440 $ — $ 226,440 Obligations of states and political subdivisions — 20,212 — 20,212 U.S. government agencies — 6,688 — 6,688 Corporate obligations — 35,342 7,792 43,134 Other debt securities — 16,919 — 16,919 Total debt securities $ — $ 305,601 $ 7,792 $ 313,393 Equity securities-financial services 25 — — 25 Derivatives and hedging activities — 303 — 303 Liabilities: Derivatives and hedging activities: — 1,011 — 1,011 The following table presents a summary of changes in the fair value of the Company’s Level III investments for the three month periods ended December 31, 2019 and 2018 (in thousands). Fair Value Measurement Using Significant Unobservable Inputs (Level III) Three Months Ended December 31, 2019 December 31, 2018 Beginning balance $ 7,792 $ 7,738 Purchases, sales, issuances, settlements, net — — Total unrealized gain (loss): Included in earnings — — Included in other comprehensive income (loss) 29 (96 ) Transfers in and/or out of Level III — — $ 7,821 $ 7,642 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 December 31, 2019 and September 30, 2019 by level within the fair value hierarchy: Non-Recurring Fair Value Measurements at Reporting Date (in thousands) December 31, 2019 Level I Level II Level III Total Foreclosed real estate $ — $ — $ 343 $ 343 Impaired loans — — 7,546 7,546 September 30, 2019 Level I Level II Level III Total Foreclosed real estate $ — $ — $ 240 $ 240 Impaired loans — — 8,128 8,128 The following tables present additional quantitative information about assets measured at fair value on a nonrecurring basis and for which the Company has utilized Level 3 inputs to determine fair value: Quantitative Information about Level 3 Fair Value Measurements (dollars in thousands) Fair Value Estimate Valuation Techniques Unobservable Input Range December 31, 2019 Impaired loans $ 7,546 Appraisal of collateral (1) Appraisal adjustments (2) 0% to 35% (20.7%) Foreclosed real estate owned 343 Appraisal of collateral (1) Appraisal adjustments (2) 20% to 46% (25.9%) Quantitative Information about Level 3 Fair Value Measurements (dollars in thousands) Fair Value Estimate Valuation Techniques Unobservable Input Range 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 December 31, 2019, 123 impaired loans with a carrying value of $7.8 million were reduced by specific valuation allowance totaling $210,000 resulting in a net fair value of $7.5 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. Assets and Liabilities not Required to be Measured and Reported at Fair Value The following tables provide the carrying value and fair value for certain financial instruments that are not required to be measured or reported at fair value on the consolidated Balance Sheet at December 31, 2019 and September 30, 2019 by level within the fair value hierarchy: December 31, 2019 (in thousands) Carrying Level I Level II Level III Total Fair Value Financial assets: Cash and cash equivalents $ 42,552 $ 42,552 $ — $ — $ 42,552 Loans receivable, net 1,345,311 — — 1,332,511 1,332,511 Accrued interest receivable 6,308 6,308 — — 6,308 Regulatory stock 11,126 11,126 — — 11,126 Mortgage servicing rights 167 — — 241 241 Bank owned life insurance 39,842 39,842 — — 39,842 Financial liabilities: Deposits $ 1,349,364 $ 882,214 $ — $ 467,567 $ 1,349,781 Short-term borrowings 104,719 104,719 — — 104,719 Other borrowings 137,960 — — 138,776 138,776 Advances by borrowers for taxes and insurance 10,361 10,361 — — 10,361 Accrued interest payable 1,379 1,379 — — 1,379 September 30, 2019 (in thousands) Carrying Level I Level II Level III Total Fair Value Financial assets: Cash and cash equivalents $ 52,242 $ 52,242 $ — $ — $ 52,242 Certificates of deposit — — — — — Loans receivable, net 1,328,653 — — 1,313,231 1,313,231 Accrued interest receivable 6,225 6,225 — — 6,225 Regulatory stock 11,579 11,579 — — 11,579 Mortgage servicing rights 177 — — 241 241 Bank owned life insurance 39,601 39,601 — — 39,601 Financial liabilities: Deposits $ 1,342,830 $ 900,252 $ — $ 443,063 $ 1,343,315 Short-term borrowings 107,701 107,701 — — 107,701 Other borrowings 140,581 — — 141,427 141,427 Advances by borrowers for taxes and insurance 6,700 6,700 — — 6,700 Accrued interest payable 1,384 1,384 — — 1,384

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	12. Derivatives and Hedging Activities Risk Management Objective of Using Derivatives The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities and through the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to certain variable rate borrowings. Fair Values of Derivative Instruments on the Consolidated Balance Sheet The table below presents the fair value of the Company’s derivative financial instruments as well as their classification on the Consolidated Balance Sheet as of December 31, 2019 and September 30, 2019 (in thousands). Fair Values of Derivative Instruments Asset Derivatives As of December 31, 2019 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 $ 219 $ 50,000 Other Assets $ 303 Commercial Loans 8,701 Other Assets 56 - Other Assets - Total $ 58,701 $ 275 $ 50,000 $ 303 Fair Values of Derivative Instruments Liability Derivatives As of December 31, 2019 As of September 30, 2019 Hedged Item Notional Amount Balance Sheet Location Fair Value Notional Amount Balance Sheet Location Fair Value FHLB Advances $ 35,000 Other Liabilties $ 401 $ 35,000 Other Liabilties $ 513 Brokered Deposits 50,000 Other Liabilties 377 50,000 Other Liabilties 498 Commercial Loans 14,932 Other Liabilties 70 - Other Liabilties - Total $ 99,932 $ 848 $ 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 December 31, 2019, the Company had twelve interest rate swaps with a notional principal amount of $158.6 million associated with the Company’s cash outflows associated with various FHLB advances, brokered certificates and commercial loans. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is initially reported in other comprehensive income (outside of earnings), net of tax, and subsequently reclassified to earnings when the hedged transaction affects earnings, and the ineffective portion of changes in the fair value of the derivative is recognized directly in earnings. The Company assesses the effectiveness of each hedging relationship by comparing the changes in cash flows of the derivative hedging instrument with the changes in cash flows of the designated hedged transactions. The Company did not recognize any hedge ineffectiveness in earnings during the periods ended December 31, 2019 and 2018. Amounts reported in accumulated other comprehensive loss related to derivatives that will be reclassified to interest income/expense as interest payments are made/received on the Company’s variable-rate assets/liabilities. During the three months ended December 31, 2019 and 2018, the Company had $68,000 and $217,000 respectively, of gains reclassified to interest expense. During the next twelve months, the Company estimates that $254,000 will be reclassified as a decrease in interest expense. The table below presents the effect of the Company’s cash flow hedge accounting on Accumulated Other Comprehensive Income for the three month periods ended December 31, 2019 and 2018 (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 December 31, 2019, the Company had derivatives in a net liability position and was required to post $500,000 in collateral against its obligations under these agreements. As of September 30, 2019, the Company was required to post $710,000 in collateral against its obligations under these agreements. If the Company had breached any of these provisions at December 31, 2019 and September 30, 2019, it could have been required to settle its obligations under the agreements at the termination value.

Contingent Liabilities	13. Contingent Liabilities Legal Proceedings The Company and its subsidiaries are subject to various legal actions arising in the normal course of business. In the opinion of Management, the resolution of these legal actions is not expected to have a material adverse effect on the Company’s results of operations. The Bank was named as a defendant in an action commenced on December 8, 2016 by one plaintiff who 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. The Bank will continue to vigorously defend against such allegations. To the extent that pending or threatened litigation could result in exposure to the Bank, the amount of such exposure is not currently estimable.

Revenue From Contract With Customer [Abstract]
Revenue Recognition	14. Effective October 1, 2018, the Company adopted ASU 2014-09 Revenue from Contracts with Customers- Topic 606 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.

Leases [Abstract]
Leases	15. A lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. 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. Substantially 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) 12/31/2019 Lease Right-of-Use Assets Classification Operating lease right-of-use assets Other assets $ 7,061 Total Lease Right-Of-Use Assets $ 7,061 (in thousands) 12/31/2019 Lease Liabilities Classification Operating lease Liabilities Other liabilities $ 7,083 Total Lease Liabilities $ 7,083 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.

Accounting Changes And Error Corrections [Abstract]
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 utilized the modified-retrospective transition approach prescribed by ASU 2018-11.

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) 12/31/2019 Lease Right-of-Use Assets Classification Operating lease right-of-use assets Other assets $ 7,061 Total Lease Right-Of-Use Assets $ 7,061 (in thousands) 12/31/2019 Lease Liabilities Classification Operating lease Liabilities Other liabilities $ 7,083 Total Lease Liabilities $ 7,083
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. 12/31/2019 Weighted average remaining lease term Operating leases 14.0 years Weighted average discount rate Operating leases 2.37 %
Summary of Components of Lease Cost	The following table represents lease costs and other lease information. As the Company elected, for all classes of underlying assets, not to separate lease and non-lease components and instead to account for them as a single lease component, the variable lease cost primarily represents variable payments such as common area maintenance and utilities. Lease Costs (in thousands) Three Months Ended 12/31/2019 Operating lease cost $ 254 Variable lease cost 59 Net lease cost $ 313
