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. Concurrently, 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, and Luzerne 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. 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 significantly 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, 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 Held for Sale

	Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value in the aggregate. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income. All sales are made without recourse.

	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.

	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 consists of specific and general components. The specific component relates to loans that are classified as impaired. For such loans an allowance 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.

	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 Central Bankers Bank stock. Regulatory stocks are 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 35 basis points of the outstanding member asset value plus 4.6 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, 2014.

	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, 2014 and 2013, were not impaired. Total servicing assets included in other assets as of September 30, 2014 and 2013, were $688,000 and $382,000, 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.

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 2014 or 2013.

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 2014 and 2013.

The following tables provide information for the carrying amount of goodwill and intangible assets.

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 Employee Stock Ownership Plan (“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. Accounting literature also provides guidance on the accounting for and disclosure of unrecognized tax benefits, interest, and penalties. In accordance with generally accepted accounting principles, interest or penalties incurred for income taxes will be recorded as a component of other expenses.

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, as well as changes in unrecognized pension cost.

The components of accumulated other comprehensive income (loss), net of tax, as of year-end were as follows:



		2014			2013			2012
Net unrealized gain on securities available for sale		$	649		$	71		$	6,208
Net unrecognized pension cost			(3,228	)		(1,306	)		(4,450	)


Total		$	(2,579	)	$	(1,235	)	$	1,758


Fair Value Measurements

We group our assets 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.

We base our fair values 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 our assets are obtained from independent pricing services that we have engaged for this purpose. When available, we, or our 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 our 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.

Recent Accounting Pronouncements

In June 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-08, Financial Services – Investment Companies (Topic 946): Amendments to the Scope, Measurement, and Disclosure Requirements. The amendments in this Update affect the scope, measurement, and disclosure requirements for investment companies under U.S. GAAP. The amendments do all of the following: (1) change the approach to the investment company assessment in Topic 946, clarify the characteristics of an investment company, and provide comprehensive guidance for assessing whether an entity is an investment company; (2) require an investment company to measure noncontrolling ownership interests in other investment companies at fair value rather than using the equity method of accounting; and (3) require the following additional disclosures: (a) the fact that the entity is an investment company and is applying the guidance in Topic 946, (b) information about changes, if any, in an entity’s status as an investment company, and (c) information about financial support provided or contractually required to be provided by an investment company to any of its investees. The amendments in this Update are effective for an entity’s interim and annual reporting periods in fiscal years that begin after December 15, 2013. Earlier application is prohibited. This Update is not expected to have a significant impact on the Company’s financial statements.

In July 2013, the FASB issued ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. This Update applies to all entities that have unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date. An unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The assessment of whether a deferred tax asset is available is based on the unrecognized tax benefit and deferred tax asset that exist at the reporting date and should be made presuming disallowance of the tax position at the reporting date. The amendments in this Update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The amendments should be applied prospectively to all unrecognized tax benefits that exist at the effective date. Retrospective application is permitted. This Update is not expected to have a significant impact on the Company’s financial statements.

In January 2014, the FASB issued ASU 2014-01, Investments – Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects. The amendments in this Update permit reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). The amendments in this Update should be applied retrospectively to all periods presented. A reporting entity that uses the effective yield method to account for its investments in qualified affordable housing projects before the date of adoption may continue to apply the effective yield method for those preexisting investments. The amendments in this Update are effective for public business entities for annual periods and interim reporting periods within those annual periods, beginning after December 15, 2014. Early adoption is permitted. This Update is not expected to have a significant impact on the Company’s financial statements.



In January 2014, the FASB issued ASU 2014-04, Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The amendments in this Update clarify that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The amendments in this Update are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. An entity can elect to adopt the amendments in this Update using either a modified retrospective transition method or a prospective transition method. This Update is not expected to have a significant impact on the Company’s financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (a new revenue recognition standard). The Update’s core principle is that a company will recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, this update specifies the accounting for certain costs to obtain or fulfill a contract with a customer and expands disclosure requirements for revenue recognition. This Update is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. The Company is evaluating the effect of adopting this new accounting Update.

In June 2014, the FASB issued ASU 2014-11, Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures. The amendments in this Update change the accounting for repurchase-to-maturity transactions to secured borrowing accounting. For repurchase financing arrangements, the amendments require separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty, which will result in secured borrowing accounting for the repurchase agreement. The amendments also require enhanced disclosures. The accounting changes in this Update are effective for the first interim or annual period beginning after December 15, 2014. An entity is required to present changes in accounting for transactions outstanding on the effective date as a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. Earlier application is prohibited. The disclosure for certain transactions accounted for as a sale is required to be presented for interim and annual periods beginning after December 15, 2014, and the disclosure for repurchase agreements, securities lending transactions, and repurchase-to-maturity transactions accounted for as secured borrowings is required to be presented for annual periods beginning after December 15, 2014, and for interim periods beginning after March 15, 2015. The disclosures are not required to be presented for comparative periods before the effective date. This Update is not expected to have a significant impact on the Company’s financial statements.



In June 2014, the FASB issued ASU 2014-12, Compensation-Stock Compensation (Topic 718): Accounting for Share-Based Payments when the Terms of an Award Provide that a Performance Target Could Be Achieved After the Requisite Service Period. The amendments require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. The amendments in this Update are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Earlier adoption is permitted. Entities may apply the amendments in this Update either (a) prospectively to all awards granted or modified after the effective date or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. If retrospective transition is adopted, the cumulative effect of applying this Update as of the beginning of the earliest annual period presented in the financial statements should be recognized as an adjustment to the opening retained earnings balance at that date. Additionally, if retrospective transition is adopted, an entity may use hindsight in measuring and recognizing the compensation cost. This Update is not expected to have a significant impact on the Company’s financial statements.

In August 2014, the FASB issued ASU 2014-14, Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40). The amendments in this Update require that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if the following conditions are met: (1) the loan has a government guarantee that is not separable from the loan before foreclosure, (2) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim, and (3) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. The amendments in this Update are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. This Update is not expected to have a significant impact on the Company’s financial statements.

In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements -Going Concern (Subtopic 205-40). The amendments in this Update provide guidance in accounting principles generally accepted in the United States of America about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The amendments in this Update are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. This Update is not expected to have a significant impact on the Company’s financial statements.

	The Company’s investment securities portfolio contains unrealized losses on securities, including mortgage-related instruments issued or backed by the full faith and credit of the United States government, or generally viewed as having the implied guarantee of the U.S. government, corporate obligations, and debt obligations of a U.S. state or political subdivision.

	The Company reviews its position quarterly and has asserted that at September 30, 2014 and 2013, 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, 2014 and 2013, 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.

	Net loans		$	1,058,267		$	928,230




	Included in the September 30, 2014, balances are loans acquired from First National Community Bank. The balance of these loans as of the acquisition date of January 24, 2014, was as follows:



	Real estate loans:
	Residential		$	933
	Home equity loans and lines of credit			77
	Other			20


	Total loans		$	1,030


	Included in the September 30, 2014 balances are loans acquired from Franklin Security Bank. The balance of these loans as of the acquisition date of April 4, 2014, was as follows:



	Real estate loans:
	Residential		$	17,151
	Commercial			38,247
	Commercial			9,308
	Obligation of states and political subdivisions			7,309
	Home equity loans and lines of credit			16
	Auto loans			78,794
	Other			1,363


	Total loans		$	152,188


	Purchased loans acquired in a business combination are recorded at fair value on their purchase date without a carryover of the related allowance for loan losses.

	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. Purchased credit-impaired loans are loans that have evidence of credit deterioration since origination and for which it is probable at the date of acquisition that the Company will not collect all contractually required principal and interest payments. The fair value of purchased credit-impaired loans from First Star Bank, on the acquisition date, was determined, primarily based on the fair value of loan collateral. The carrying value of purchased loans acquired with deteriorated credit quality was $5.1 million at September 30, 2014. As of the acquisition dates, none of the loans acquired from First National Community Bank and Franklin Security Bank had evidence of credit deterioration.

	On the acquisition date, the preliminary estimate of the unpaid principal balance for all loans evidencing credit impairment acquired in the First Star Bank acquisition was $12.9 million and the fair value of the loans was $7.3 million. Total contractually required payments on these loans, including interest, at the acquisition date was $13.9 million. However, the Company’s preliminary estimate of expected cash flows was $8.8 million. At such date, the Company established a credit risk related non-accretable discount (a discount representing amounts which are not expected to be collected from the customer nor liquidation of collateral) of $5.1 million relating to these impaired loans, reflected in the recorded net fair value. Such amount is reflected as a non-accretable fair value adjustment to loans. The Company further estimated the timing and amount of expected cash flows in excess of the estimated fair value and established an accretable discount of $1.4 million on the acquisition date relating to these impaired loans.



	Changes in the accretable yield for purchased credit-impaired loans were as follows, since acquisition, for the periods ended September 30, 2014 and 2013.



Balance at beginning of period		$	—		$	1,098
Reclassification and other			872			—
Accretion			(702	)		(1,098	)


Balance at end of period		$	170		$	—


Included in reclassification and other for loans acquired without specific evidence of deterioration in credit quality was $872,000 of reclassifications from nonaccretable discounts to accretable discounts in 2014.

The following table presents additional information regarding loans acquired and accounted for in accordance with ASC 310-30 (in thousands):



		September 30, 2014			September 30, 2013

There has been $157,000 in allowance for loan losses recorded for acquired loans with or without specific evidence of deterioration in credit quality as of September 30, 2014. There has been no allowance for loan losses recorded for acquired loans with or without specific evidence of deterioration in credit quality as of September 30, 2013. In addition, no allowance for loan losses has been reversed.

Loans serviced by the Company for others amounted to $104,810,000 and $80,986,000 at September 30, 2014 and 2013, respectively.

The Company’s primary business activity is with customers located within its local trade area. 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, 2014 and 2013, loans outstanding to individuals and businesses are dependent upon the local economic conditions in its immediate trade area.

At September 30, 2014, 2013, and 2012, the Company had nonaccrual loans of $21,912,000, $23,279,000, and $23,707,000, respectively. Additional interest income that would have been recorded under the original terms of the loan agreements amounted to $1,054,000, $883,000, and $592,000, for the years ended September 30, 2014, 2013, and 2012, respectively.

Impaired loans for the years ended September 30 are summarized as follows (in thousands):

The Company maintains a loan review system, which allows for a periodic review of our loan portfolio and the early identification of potential impaired loans. Such system takes into consideration, among other things, delinquency status, size of loans, type and market value of collateral, and financial condition of the borrowers. Specific loan loss allowances are established for identified losses based on a review of such information. A loan evaluated for impairment is considered to be impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. All loans identified as impaired are evaluated independently. The Company does not aggregate such loans for evaluation purposes. Impairment is measured on a loan-by-loan basis for commercial and construction loans by the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral-dependent.

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 of interest 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. 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 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 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 $500,000 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. 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 table presents 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, 2014 and 2013 (in thousands):

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.

The allowance for loan losses (“ALL”) is maintained at a level necessary to absorb loan losses that are both probable and reasonably estimable. Management, in determining the allowance for loan losses, considers the losses inherent in its loan portfolio and changes in the nature and volume of loan activities, along with the general economic and real estate market conditions. The allowance for loan losses consists of 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 September 30, 2014, 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 allowance 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, 2014 (in thousands):

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 increased provisions to the residential real estate, commercial and home equity loans, and lines of credit segments for the year ended September 30, 2014, due to increased charge-off activity in those segments. The Company allocated decreased allowance for loan loss provisions to the commercial real estate segment due to actual loss experience being less than previously estimated. Despite the above allocations, the allowance for loan losses is general in nature and is available to absorb losses from any loan segment.

	All borrowings from the FHLB are secured by a blanket lien on qualified collateral, defined principally as investment securities and mortgage loans that are owned by the Company free and clear of any liens or encumbrances. At September 30, 2014, the Company had a borrowing limit of approximately $576.4 million, with a variable rate of interest, based on the FHLB’s cost of funds.

	Included above is one convertible note for $5,000,000 which is convertible to a variable-rate advance on specific dates at the discretion of the FHLB. Should the FHLB convert this advance, the Bank has the option of accepting the variable rate or repaying the advance without penalty.

	The FHLB long-term advances are secured by qualifying assets of the Bank, which include the FHLB stock, securities, and first-mortgage loans.

	Included in other borrowings are sales of securities under repurchase agreements. Repurchase agreements are treated as financings with the obligations to repurchase securities sold reflected as a liability in the balance sheet. The dollar amount of securities underlying the agreements remains recorded as an asset, although the securities underlying the agreements are delivered to the brokers who arranged the transactions.

	Securities sold under agreements to repurchase and other borrowings are secured by U.S. government mortgage-backed securities with a carrying value of $14,795,000 at September 30, 2013.

	Net deferred tax assets		$	12,027		$	11,691

	The Company establishes a valuation allowance for deferred tax assets when management believes that the deferred tax assets are not likely to be realized either through a carryback to taxable income in prior years, future reversals of existing taxable temporary differences, and, to a lesser extent, future taxable income.
	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 Statement of Income. The Company’s federal and state income tax returns for taxable years through 2010 have been closed for purposes of examination by the Internal Revenue Service and the Pennsylvania Department of Revenue.

	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.
	Retained earnings include $4.6 million at September 30, 2014, for which no provision for federal income tax has been made. This amount represents deductions for bad debt reserves for tax purposes, which were only allowed to savings institutions that met certain definitional tests prescribed by the Internal Revenue Code of 1986, as amended. The Small Business Job Protection Act of 1996 eliminated the special bad debt deduction granted solely to thrifts. Under the terms of the Act, there would be no recapture of the pre-1988 (base year) reserves. However, these pre-1988 reserves would be subject to recapture under the rules of the Internal Revenue Code if the Bank itself pays a cash dividend in excess of earnings and profits or liquidates. The Act also provides for the recapture of deductions arising from the Bank’s applicable excess reserve, which is defined as the total amount of reserve over the base year reserve. The Bank’s total reserve exceeds the base year reserve, and deferred taxes have been provided for this excess.

Commitments	11	COMMITMENTS
	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):


			2014		2013

	Commitments to extend credit		$	40,615	$	22,333
	Standby letters of credit			7,521		4,769
	Unfunded lines of credit			44,039		42,016
	Commitments to extend credit consist of fixed-rate commitments with interest rates ranging from 2.95 percent to 4.64 percent. The commitments outstanding at September 30, 2014, 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 period with renewal option subject to prior approval by management. Fees earned from the issuance of these letters are recognized over the coverage period. For secured letters of credit, the collateral is typically Company deposit instruments.

	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 3.25 percent and requires an annual payment of principal and interest of $718,000 through December of 2036. The Company’s ESOP, which is internally leveraged, does not report the loans receivable extended to the ESOP as assets and does not report the ESOP debt due to the Company.



	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 $500,000, $485,000, and $469,000, for the years ended September 30, 2014, 2013, and 2012, respectively.

	Equity Incentive Plan

	The Company implemented the ESSA Bancorp, Inc. 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. Certain officers were granted in aggregate 30,000 shares of restricted stock on April 1, 2013 and 19,880 of restricted stock on July 22, 2014. In accordance with generally accepted accounting principles, the Company expenses the fair value of all share-based compensation grants over the requisite service periods.

	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 vested over a five-year service period and expire ten years after grant date. Management recognizes compensation expense for the fair values of these awards, which vested on a straight-line basis over the requisite service period of the awards.

	The 2008 restricted shares vested over a five-year service period. The 2013 restricted shares vested over an 18-month service period. The 2014 restricted shares vest over a 39-month service period. The product of the number of shares granted and the grant date market price of the Company’s common stock determine the fair value of restricted shares under the Company’s restricted stock plan. Management recognizes compensation expense for the fair value of restricted shares on a straight-line basis over the requisite service period for the entire award.



	During the years ended September 30, 2014, 2013, and 2012, the Company recorded $219,000, $1.5 million, and $2.2 million of share-based compensation expense, consisting of stock option expense of $0, $458,000, and $687,000, and restricted stock expense of $219,000, $1.1 million, and $1.5 million, respectively. Expected future compensation expense relating to the 14,906 restricted shares at September 30, 2014, is $204,000 over the remaining vesting period of three years.

	The following is a summary of the Company’s stock option activity and related information for its option plan for the year ended September 30, 2014.

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.



The following table sets forth the change in plan assets and benefit obligation at September 30 (in thousands):

The Bank’s defined benefit pension plan weighted-average asset allocations at September 30, by asset category, are as follows:



Asset Category		2014			2013

Cash and fixed income securities			40.2	%		35	%
Equity securities			59.7			64.9
Other			0.1			0.1


Total			100	%		100	%


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 expects to contribute $520,000 to its pension plan in 2015.

Estimated future benefit payments, which reflect expected future service, as appropriate, are as follows (in thousands):



2015		$	81
2016			87
2017			112
2018			317
2019			397

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 suspended in January 2011.

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 $680,000 at September 30, 2014 and 2013, which represent the estimated present value (using a discount rate of 6.00 percent) of the benefits earned under this agreement. There was no expense related to the supplemental executive retirement plan for the years ended September 30, 2014, 2013, and 2012.

	The Bank is required to maintain reserve funds in cash or in deposit with the Federal Reserve Bank. The required reserve at September 30, 2014 and 2013, was $7,860,000 and $3,476,000, respectively.

	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. In addition, the Bank is required to notify the Federal Reserve Board prior to declaring a dividend to the Company and receive the nonobjection of the Federal Reserve Board to any such dividend.

Regulatory Capital Requirements	15	REGULATORY CAPITAL REQUIREMENTS

	Federal regulations require the Bank to maintain certain minimum amounts of capital. Specifically, the Bank is required to maintain certain minimum dollar amounts and ratios of Total and Tier I capital to risk-weighted assets and of Tier I capital to average total 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, 2014, the Bank met all capital adequacy requirements to which it is subject.

	As of September 30, 2014 and 2013, the FDIC categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be classified as a well-capitalized financial institution, Total risk-based, Tier I risk-based, core capital, and tangible equity capital ratios must be at least 10 percent, 6 percent, 5 percent, and 1.5 percent, respectively. There have been no conditions or events since the notification that management believes have changed the Bank’s category.

	The following table reconciles the Bank’s capital under U.S. generally accepted accounting principles to regulatory capital (in thousands):



			2014			2013

Fair Value Measurements	16	FAIR VALUE MEASUREMENTS

	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.

	The following table presents information about the Company’s securities, real estate owned, and impaired loans measured at fair value as of September 30, 2014 and 2013, and indicates the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value:

Financial assets and liabilities must be identified as having been valued according to a specified level of input, I, II, or III. Level I 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 II inputs utilize inputs other than quoted prices included in Level I that are observable for the asset, either directly or indirectly. Level II 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 III 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 II 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 I inputs are limited to actively traded equity securities whose market price is readily available from the New York Stock Exchange or the NASDAQ exchange. 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, 2014, 264 impaired loans with a carrying value of $37.0 million were reduced by specific valuation allowance totaling $468,000 resulting in a net fair value of $36.5 million based on Level III inputs. At September 30, 2013, 233 impaired loans with a carrying value of $37.2 million were reduced by specific valuation allowance totaling $819,000 resulting in a net fair value of $36.4 million based on Level III 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 III inputs to determine fair value:

-3	Includes qualitative adjustments by management and estimated liquidation expenses.

Investment Securities Available for Sale

Fair values for securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges or matrix pricing, which is a mathematical technique that is widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark-quoted securities.



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 $36,965,000 less their valuation allowances of $468,000 at September 30, 2014. The fair value consists of the loan balances of $37,226,000 less their valuation allowances of $819,000 at September 30, 2013.

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.

	Financial instruments are defined as cash, evidence of an ownership interest in an entity, or a contract which creates an obligation or right to receive or deliver cash or another financial instrument from/to a second entity on potentially favorable or unfavorable terms.

	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 Company, 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 Regulatory 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 regulatory stock is not actively traded on a secondary market and held exclusively by member financial institutions, the fair market value approximates the carrying amount.

Certificates of Deposit, Loans Receivable, Deposits, Other Borrowings, and Mortgage Servicing Rights

The fair values for loans and mortgage servicing rights are estimated by discounting contractual cash flows and adjusting for prepayment estimates. Discount rates are based upon rates generally charged for such loans with similar characteristics. Demand, savings, and money market deposit accounts are valued at the amount payable on demand as of year-end. Fair values for certificates of deposit, time deposits, and 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 deposits and 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. The contractual amounts of unfunded commitments are presented in Note 11.

Business Combinations [Abstract]
Acquisitions	18	ACQUISITIONS

	Acquisition of FNCB Branch

	On January 24, 2014, the Company closed on a purchase transaction to acquire a branch facility, customer deposits, and loans of First National Community Bank (FNCB), the subsidiary of First National Community Bancorp, Inc., in a cash transaction. The acquired branch is located in the Monroe County, Pennsylvania market. Under the terms of the agreement, the Company acquired all of the branch facilities, customer deposits and loans of FNCB and received net cash of $4.6 million.

	The acquired assets and assumed liabilities were measured at fair values. Management made significant estimates and exercised significant judgment in accounting for the acquisition. Management measured loan fair values based on loan file reviews (including borrower financial statements or tax returns), appraised collateral values, expected cash flows and historical loss factors of FNCB. Real estate acquired through foreclosure was primarily valued based on appraised collateral values.

	The business combination resulted in the acquisition of loans without evidence of credit quality deterioration. FNCB’s loans were fair valued by discounting both expected principal and interest cash flows using an observable discount rate for similar instruments that a market participant would consider in determining fair value. Additionally, consideration was given to management’s best estimates of default rates and payment speeds. At acquisition, FNCB’s loan portfolio without evidence of deterioration totaled $1.0 million and was recorded at a fair value of $1.0 million.



	Total purchase price		$	4,640

	Net cash acquired:
	Cash		$	11
	Loans receivable and accrued interest receivable			1,033
	Premises and equipment, net			1,626
	Certificates of deposits			(3,069	)
	Deposits other than certificates of deposits			(5,683	)


				(6,082	)

	Goodwill resulting from FNCB purchase		$	1,442


	Supplemental pro forma financial information related to the FNCB acquisition has not been provided as it would be impracticable to do so. Historical financial information regarding the acquired branch is not accessible and, thus, the amounts would require estimates so significant as to render the disclosure irrelevant.



	Acquisition of Franklin Security Bancorp, Inc.

	On April 4, 2014, the Company closed on a merger transaction to acquire Franklin Security Bancorp, Inc., the parent company of Franklin Security Bank, in a cash transaction. Under the terms of the merger agreement, the Company acquired all of the outstanding shares of Franklin Security Bancorp, Inc. for a total cash purchase price of approximately $15.7 million. Franklin Security Bank has been merged into ESSA Bank & Trust, with ESSA Bank & Trust as the surviving entity. The acquisition added two branch locations in the Scranton/Wilkes-Barre, Pennsylvania, market, establishing the Company’s presence in that market.

	The acquired assets and assumed liabilities were measured at fair values. Management made significant estimates and exercised significant judgment in accounting for the acquisition. Management measured loan fair values based on loan file reviews (including borrower financial statements or tax returns), appraised collateral values, expected cash flows, and historical loss factors of Franklin Security Bank. Real estate acquired through foreclosure was primarily valued based on appraised collateral values. The Company also recorded an identifiable intangible asset representing the core deposit base of Franklin Security Bank based on management’s evaluation of the cost of such deposits relative to alternative funding sources. Management used market quotations to measure the fair value of investment securities and FHLB advances. The business combination resulted in the acquisition of loans without evidence of credit quality deterioration. At the acquisition date, the Company determined that there were no purchased impaired loans. The method of measuring carrying value of purchased loans differs from loans originated by the Company (originated loans), and as such, the Company identifies purchased loans and purchased loans with a credit quality discount and originated loans at amortized cost.

	Franklin Security Bank’s loans without evidence of credit deterioration were measured to fair value by discounting both expected principal and interest cash flows using an observable discount rate for similar instruments that a market participant would consider in determining fair value. Additionally, consideration was given to management’s best estimates of default rates and payment speeds. At acquisition, Franklin Security Bank’s loan portfolio without evidence of deterioration totaled $155.3 million and was recorded at a fair value of $152.2 million.



	The following condensed statement reflects the values assigned to Franklin Security Bancorp, Inc.’s net assets as of the acquisition date:

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 significantly 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, 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 Held for Sale	Loans Held for Sale
	Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value in the aggregate. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income. All sales are made without recourse.
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.

	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 consists of specific and general components. The specific component relates to loans that are classified as impaired. For such loans an allowance 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.

	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 Central Bankers Bank stock. Regulatory stocks are 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 35 basis points of the outstanding member asset value plus 4.6 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, 2014.
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, 2014 and 2013, were not impaired. Total servicing assets included in other assets as of September 30, 2014 and 2013, were $688,000 and $382,000, 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.
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 2014 or 2013.

	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 2014 and 2013.
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 Employee Stock Ownership Plan (“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. Accounting literature also provides guidance on the accounting for and disclosure of unrecognized tax benefits, interest, and penalties. In accordance with generally accepted accounting principles, interest or penalties incurred for income taxes will be recorded as a component of other expenses.
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, as well as changes in unrecognized pension cost.
Fair Value Measurements	Fair Value Measurements
	We group our assets 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.
	We base our fair values 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 our assets are obtained from independent pricing services that we have engaged for this purpose. When available, we, or our 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 our 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.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In June 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-08, Financial Services – Investment Companies (Topic 946): Amendments to the Scope, Measurement, and Disclosure Requirements. The amendments in this Update affect the scope, measurement, and disclosure requirements for investment companies under U.S. GAAP. The amendments do all of the following: (1) change the approach to the investment company assessment in Topic 946, clarify the characteristics of an investment company, and provide comprehensive guidance for assessing whether an entity is an investment company; (2) require an investment company to measure noncontrolling ownership interests in other investment companies at fair value rather than using the equity method of accounting; and (3) require the following additional disclosures: (a) the fact that the entity is an investment company and is applying the guidance in Topic 946, (b) information about changes, if any, in an entity’s status as an investment company, and (c) information about financial support provided or contractually required to be provided by an investment company to any of its investees. The amendments in this Update are effective for an entity’s interim and annual reporting periods in fiscal years that begin after December 15, 2013. Earlier application is prohibited. This Update is not expected to have a significant impact on the Company’s financial statements.
	In July 2013, the FASB issued ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. This Update applies to all entities that have unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date. An unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The assessment of whether a deferred tax asset is available is based on the unrecognized tax benefit and deferred tax asset that exist at the reporting date and should be made presuming disallowance of the tax position at the reporting date. The amendments in this Update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The amendments should be applied prospectively to all unrecognized tax benefits that exist at the effective date. Retrospective application is permitted. This Update is not expected to have a significant impact on the Company’s financial statements.
	In January 2014, the FASB issued ASU 2014-01, Investments – Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects. The amendments in this Update permit reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). The amendments in this Update should be applied retrospectively to all periods presented. A reporting entity that uses the effective yield method to account for its investments in qualified affordable housing projects before the date of adoption may continue to apply the effective yield method for those preexisting investments. The amendments in this Update are effective for public business entities for annual periods and interim reporting periods within those annual periods, beginning after December 15, 2014. Early adoption is permitted. This Update is not expected to have a significant impact on the Company’s financial statements.

	In January 2014, the FASB issued ASU 2014-04, Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The amendments in this Update clarify that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The amendments in this Update are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. An entity can elect to adopt the amendments in this Update using either a modified retrospective transition method or a prospective transition method. This Update is not expected to have a significant impact on the Company’s financial statements.
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (a new revenue recognition standard). The Update’s core principle is that a company will recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, this update specifies the accounting for certain costs to obtain or fulfill a contract with a customer and expands disclosure requirements for revenue recognition. This Update is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. The Company is evaluating the effect of adopting this new accounting Update.
	In June 2014, the FASB issued ASU 2014-11, Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures. The amendments in this Update change the accounting for repurchase-to-maturity transactions to secured borrowing accounting. For repurchase financing arrangements, the amendments require separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty, which will result in secured borrowing accounting for the repurchase agreement. The amendments also require enhanced disclosures. The accounting changes in this Update are effective for the first interim or annual period beginning after December 15, 2014. An entity is required to present changes in accounting for transactions outstanding on the effective date as a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. Earlier application is prohibited. The disclosure for certain transactions accounted for as a sale is required to be presented for interim and annual periods beginning after December 15, 2014, and the disclosure for repurchase agreements, securities lending transactions, and repurchase-to-maturity transactions accounted for as secured borrowings is required to be presented for annual periods beginning after December 15, 2014, and for interim periods beginning after March 15, 2015. The disclosures are not required to be presented for comparative periods before the effective date. This Update is not expected to have a significant impact on the Company’s financial statements.

	In June 2014, the FASB issued ASU 2014-12, Compensation-Stock Compensation (Topic 718): Accounting for Share-Based Payments when the Terms of an Award Provide that a Performance Target Could Be Achieved After the Requisite Service Period. The amendments require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. The amendments in this Update are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Earlier adoption is permitted. Entities may apply the amendments in this Update either (a) prospectively to all awards granted or modified after the effective date or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. If retrospective transition is adopted, the cumulative effect of applying this Update as of the beginning of the earliest annual period presented in the financial statements should be recognized as an adjustment to the opening retained earnings balance at that date. Additionally, if retrospective transition is adopted, an entity may use hindsight in measuring and recognizing the compensation cost. This Update is not expected to have a significant impact on the Company’s financial statements.
	In August 2014, the FASB issued ASU 2014-14, Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40). The amendments in this Update require that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if the following conditions are met: (1) the loan has a government guarantee that is not separable from the loan before foreclosure, (2) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim, and (3) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. The amendments in this Update are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. This Update is not expected to have a significant impact on the Company’s financial statements.
	In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements -Going Concern (Subtopic 205-40). The amendments in this Update provide guidance in accounting principles generally accepted in the United States of America about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The amendments in this Update are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. This Update is not expected to have a significant impact on the Company’s financial statements.
