The Company reviews its position quarterly and has asserted that at June 30, 2015, 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 is not other than temporary but is the result of interest rate changes that are not expected to result in the non-collection of principal and interest during the period.

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. We do 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 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. The following table includes the recorded investment and unpaid principal balances for impaired loans with the associated allowance amount, if applicable (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. 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 of 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 $500,000 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.

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. Our 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 June 30, 2015 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 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 ALL. When information confirms all or part of specific loans to be uncollectible, these amounts are promptly charged off against the ALL. The following tables summarize changes in the primary segments of the ALL for the three and nine month periods ending June 30, 2015 and 2014 (in thousands): Real Estate Loans Residential Construction Commercial Commercial Obligations of Home Auto Loans Other Unallocated Total ALL balance at March 31, 2015 $ 5,289 $ 17 $ 843 $ 635 $ 87 $ 468 $ 1,023 $ 30 $ 276 $ 8,668 Charge-offs (390 ) — — (3 ) — (3 ) (136 ) (5 ) — (537 ) Recoveries — — 54 11 — — 40 6 — 111 Provision 359 (8 ) (189 ) (2 ) 112 10 406 (3 ) (160 ) 525 ALL balance at June 30, 2015 $ 5,258 $ 9 $ 708 $ 641 $ 199 $ 475 $ 1,333 $ 28 $ 116 $ 8,767 March 31, 2014 $ 5,920 $ 26 $ 1,003 $ 369 $ 106 $ 500 $ — $ 26 $ 712 $ 8,662 Charge-offs (332 ) — (23 ) — — (10 ) — — — (365 ) Recoveries 34 — — 2 — — — 3 — 39 Provision 312 (2 ) (399 ) 222 10 (17 ) 56 (3 ) 321 500 ALL balance at June 30, 2014 $ 5,934 $ 24 $ 581 $ 593 $ 116 $ 473 $ 56 $ 26 $ 1,033 $ 8,836 Real Estate Loans Residential Construction Commercial Commercial Obligations of Home Auto Loans Other Unallocated Total ALL balance at September 30, 2014 $ 5,573 $ 11 $ 663 $ 528 $ 163 $ 470 $ 459 $ 32 $ 735 $ 8,634 Charge-offs (1,150 ) — (53 ) (30 ) — (22 ) (301 ) (5 ) — (1,561 ) Recoveries 22 — 85 20 — 12 49 6 — 194 Provision 813 (2 ) 13 123 36 15 1,126 (5 ) (619 ) 1,500 ALL balance at June 30, 2015 $ 5,258 $ 9 $ 708 $ 641 $ 199 $ 475 $ 1,333 $ 28 $ 116 $ 8,767 September 30, 2013 $ 5,787 $ 20 $ 946 $ 337 $ 130 $ 430 $ — $ 21 $ 393 $ 8,064 Charge-offs (1,255 ) — (73 ) (48 ) — (73 ) — — — (1,449 ) Recoveries 112 — 83 14 — — — 12 — 221 Provision 1,290 4 (375 ) 290 (14 ) 116 56 (7 ) 640 2,000 ALL balance at June 30, 2014 $ 5,934 $ 24 $ 581 $ 593 $ 116 $ 473 $ 56 $ 26 $ 1,033 $ 8,836 Acquired loans are recorded at fair value on their purchase date without a carryover of the related allowance for loan losses. The following table summarizes the primary segments of the ALL, segregated into amount required for loans individually evaluated for impairment and the amount required for loans collectively evaluated for impairment as of June 30, 2015 and September 30, 2014 (in thousands): Real Estate Loans Residential Construction Commercial Commercial Obligations of Home Auto Loans Other Unallocated Total Individually evaluated for impairment $ 432 $ — $ 1 $ — $ — $ 69 $ 76 $ — $ — $ 578 Collectively evaluated for impairment 4,826 9 707 641 199 406 1,257 28 116 8,189 ALL Balance at June 30, 2015 $ 5,258 $ 9 $ 708 $ 641 $ 199 $ 475 $ 1,333 $ 28 $ 116 $ 8,767 Individually evaluated for impairment $ 334 $ — $ 84 $ — $ — $ 50 $ — $ — $ — $ 468 Collectively evaluated for impairment 5,239 11 579 528 163 420 459 32 735 8,166 ALL balance at September 30, 2014 $ 5,573 $ 11 $ 663 $ 528 $ 163 $ 470 $ 459 $ 32 $ 735 $ 8,634 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. The Company allocated decreased provisions to residential real estate for the nine month period ending June 30, 2015 due to declining loan balances and impairment evaluations in those segments. The Company allocated increased provisions to commercial real estate, commercial loans and obligations of states and political subdivisions for the nine month period ending June 30, 2015 due primarily to increased loan balances. The Company allocated increased provisions in auto loans due to increased loan balances and increased charge off activity. 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 and nine months ended June 30, 2015 and 2014 (dollars in thousands).

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Equity Incentive Plan	10. Equity Incentive Plan The Company maintains the ESSA Bancorp, Inc. 2007 Equity Incentive Plan (the “Plan”). The Plan provides 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 may be issued in connection with the exercise of stock options and 679,236 may be issued as restricted stock. The Plan allows for the granting of non-qualified stock options (“NSOs”), incentive stock options (“ISOs”), and restricted stock. Options are granted at no less than the fair value of the Company’s common stock on the date of the grant. Certain officers, employees and outside directors were granted in aggregate 1,140,469 NSOs; 317,910 ISOs; and 590,320 shares of restricted stock on May 23, 2008. Certain officers were granted in aggregate 30,000 shares of restricted stock on April 1, 2013, 19,880 of restricted stock on July 22, 2014 and 21,843 shares of restricted stock on May 20, 2105. In accordance with generally accepted accounting principles , 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. Additionally, generally accepted accounting principles require the Company to report: (1) the expense associated with the grants as an adjustment to operating cash flows and (2) any benefits of realized tax deductions in excess of previously recognized tax benefits on compensation expense as a financing cash flow. Stock options vest over a five-year service period and expire ten years after grant date. The Company recognizes compensation expense for the fair values of these awards, which vest on a straight-line basis over the requisite service period of the awards. The 2013 restricted stock shares vested over an 18-month service period. The 2014 restricted shares vest over a 39 month service period. The 2015 restricted shares vest over a 40 month service period. 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 recognizes compensation expense for the fair value of restricted shares on a straight-line basis over the requisite service period for the entire award. For the nine months ended June 30, 2015 and 2014, the Company recorded $171,000 and $170,000 of share-based compensation expense, respectively, comprised of restricted stock expense. Expected future compensation expense relating to the 14,906 (2014 shares) restricted shares, at June 30, 2015 is $152,000 over the remaining vesting period of 2.25 years. Expected future compensation expense relating to the 21,843 restricted shares (2015 shares) at June 30, 2015 is $271,000 over the remaining vesting period of 3.25 years. The following is a summary of the Company’s stock option activity and related information for its option grants for the nine month period ended June 30, 2015.

Fair Value Disclosures [Abstract]
Fair Value Measurement	11. Fair Value Measurement 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. The following table presents information about the Company’s securities, other real estate owned and impaired loans measured at fair value as of June 30, 2015 and September 30, 2014 and indicates the fair value hierarchy of the valuation techniques utilized by the Bank to determine such fair value: Fair Value Measurement at June 30, 2015 Fair Value Measurements Utilized for the Quoted Prices in Active Significant Other Significant Balances as of Securities available-for-sale measured on a recurring basis Mortgage backed securities $ — $ 246,499 $ — $ 246,499 Obligations of states and political subdivisions — 49,804 — 49,804 U.S. government agencies — 44,512 — 44,512 Corporate obligations — 19,399 2,000 21,399 Trust-preferred securities — 1,741 1,730 3,471 Other debt securities — 15,165 500 15,665 Equity securities-financial services 25 — — 25 Total debt and equity securities $ 25 $ 377,120 $ 4,230 $ 381,375 Foreclosed real estate owned measured on a non-recurring basis $ — $ — $ 2,595 $ 2,595 Impaired loans measured on a non-recurring basis $ — $ — $ 33,325 $ 33,325 Fair Value Measurement at September 30, 2014 Fair Value Measurements Utilized for the Quoted Prices in Active Significant Other Significant Balances as of Securities available-for-sale measured on a recurring basis Mortgage backed securities $ — $ 265,052 $ — $ 265,052 Obligations of states and political subdivisions — 42,771 — 42,771 U.S. government agencies — 47,630 — 47,630 Corporate obligations — 13,328 — 13,328 Trust-preferred securities — 3,891 1,730 5,621 Other debt securities — 6,151 500 6,651 Equity securities-financial services 2,025 — — 2,025 Total debt and equity securities $ 2,025 $ 378,823 $ 2,230 $ 383,078 Foreclosed real estate owned measured on a non-recurring basis $ — $ — $ 2,759 $ 2,759 Impaired loans measured on a non-recurring basis $ — $ — $ 36,497 $ 36,497 The following table presents a summary of changes in the fair value of the Company’s Level III investments for the three and nine month periods ended June 30, 2015 and June 30, 2014 (in thousands). Fair Value Measurement Using Significant Unobservable Inputs Three months ended June 30, 2015 June 30, 2014 Beginning balance $ 4,240 $ 1,830 Purchases, sales, issuances, settlements, net — — Total unrealized gain: Included in earnings — — Included in other comprehensive income (10 ) — Transfers in and/or out of Level III — — $ 4,230 $ 1,830 Fair Value Measurement Using Significant Unobservable Inputs Nine months ended June 30, 2015 June 30, 2014 Beginning balance $ 2,230 $ 1,800 Purchases, sales, issuances, settlements, net 2,000 — Total unrealized gain: Included in earnings — — Included in other comprehensive income — 30 Transfers in and/or out of Level III — — $ 4,230 $ 1,830 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 Bank 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 comparables. 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. 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 June 30, 2015, 246 impaired loans with a carrying value of $33.9 million were reduced by specific valuation allowance totaling $578,000 resulting in a net fair value of $33.3 million based on Level 3 inputs. At September 30, 2014, 264 impaired loans with a carrying value of $37.0 million were reduced by a specific valuation totaling $468,000 resulting in a net fair value of $36.5 million based on Level 3 inputs. The following table presents 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 (in thousands) Fair Value Valuation Unobservable Range June 30, 2015 Impaired loans $ 33,325 Appraisal of Appraisal 0% to 50% Foreclosed real estate owned 2,595 Appraisal of Appraisal 19% to 30% Quantitative Information about Level 3 Fair Value Measurements (in thousands) Fair Value Valuation Unobservable Range September 30, 2014 Impaired loans $ 36,497 Appraisal of Appraisal 0% to 35% Foreclosed real estate owned 2,759 Appraisal of Appraisal 19% to 35% (1) Fair value is generally determined through independent appraisals of the underlying collateral, which generally include various level 3 inputs which are not identifiable.

Fair value is defined as the amount at which a financial instrument could be exchanged in a current transaction between willing parties other than in a forced or liquidation sale. If a quoted market price is available for a financial instrument, the fair value would be calculated based upon the market price per trading unit of the instrument. If no readily available market exists, the fair value for financial instruments should be based upon management’s judgment regarding current economic conditions, interest rate risk, expected cash flows, future estimated losses, and other factors as determined through various option pricing formulas or simulation modeling. As many of these assumptions result from judgments made by management based upon estimates which are inherently uncertain, the resulting values may not be indicative of the amount realizable in the sale of a particular financial instrument. In addition, changes in the assumptions on which the values are based may have a significant impact on the resulting estimated values. As certain assets and liabilities, such as deferred tax assets, premises and equipment, and many other operational elements of the Bank, are not considered financial instruments but have value, this fair value of financial instruments would not represent the full market value of the Company. The Company employed simulation modeling in determining the fair value of financial instruments for which quoted market prices were not available based upon the following assumptions: Cash and Cash Equivalents, Accrued Interest Receivable, Short-Term Borrowings, Advances by Borrowers for Taxes and Insurance, and Accrued Interest Payable The fair value approximates the current book value. Bank-Owned Life Insurance The fair value is equal to the cash surrender value of the Bank-owned life insurance. Investment and Mortgage-Backed Securities Available for Sale and FHLB Stock The fair value of investment and mortgage-backed securities available for sale is equal to the available quoted market price. If no quoted market price is available, fair value is estimated using the quoted market price for similar securities. Since the FHLB stock is not actively traded on a secondary market and held exclusively by member financial institutions, the fair market value approximates the carrying amount. 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. Loans Receivable The fair values of loans are estimated using discounted cash flow analyses, using market rates at the balance sheet date that reflect the credit and interest rate-risk inherent in the loans. Projected future cash flows are calculated based upon contractual maturity or call dates, projected repayments and prepayments of principal. Generally, for variable rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values. Mortgage Servicing Rights The Company utilizes a third party provider to estimate the fair value of certain loan servicing rights. Fair value for the purpose of this measurement is defined as the amount at which the asset could be exchanged in a current transaction between willing parties, other than in a forced liquidation. Deposits The fair values disclosed for demand, savings, and money market deposit accounts are valued at the amount payable on demand as of quarter-end. Fair values for time deposits are estimated using a discounted cash flow calculation that applies contractual costs currently being offered in the existing portfolio to current market rates being offered for deposits of similar remaining maturities. Other Borrowings Fair values for other borrowings are estimated using a discounted cash flow calculation that applies contractual costs currently being offered in the existing portfolio to current market rates being offered for other borrowings of similar remaining maturities. Commitments to Extend Credit These financial instruments are generally not subject to sale, and fair values are not readily available. The carrying value, represented by the net deferred fee arising from the unrecognized commitment, and the fair value, determined by discounting the remaining contractual fee over the term of the commitment using fees currently charged to enter into similar agreements with similar credit risk, are not considered material for disclosure.
