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

Accounting Changes And Error Corrections [Abstract]	'

	4	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. 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 ASU 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 ASU is not expected to have a significant impact on the Company’s financial statements.
	In January 2014, FASB issued ASU 2014-01, Investments – Equity Method and Join 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 ASU 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 ASU 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, debt obligations of a U.S. state or political subdivision and corporate debt obligations.

	The Company reviews its position quarterly and has asserted that at March 31, 2014, the declines outlined in the above table represent temporary declines and the Company would not be required to sell the security before its anticipated recovery in market value.

	The Company has concluded that any impairment of its investment securities portfolio is not other than temporary but is the result of interest rate changes that are not expected to result in the non-collection of principal and interest during the period.

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

Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer and residential mortgage loans for impairment disclosures, unless such loans are part of a larger relationship that is impaired, or are classified as a troubled debt restructuring.

A loan is considered to be a troubled debt restructuring (“TDR”) loan when the Company grants a concession to the borrower because of the borrower’s financial condition that it would not otherwise consider. Such concessions include the reduction of interest rates, forgiveness of principal or interest, or other modifications of interest rates that are less than the current market rate for new obligations with similar risk. TDR loans that are in compliance with their modified terms and that yield a market rate may be removed from the TDR status after a period 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.

Management 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 currently protected but are potentially weak, resulting in an undue and unwarranted credit risk, but not to the point of justifying a Substandard classification. 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. The portion of any loan that represents a specific allocation of the allowance for loan losses is placed in the Doubtful category. Any portion of a loan that has been charged off is placed in the Loss category.

To help ensure that risk ratings are accurate and reflect the present and future capacity of borrowers to repay a loan as agreed, the Bank has a structured loan rating process with several layers of internal and external oversight. Generally, consumer and residential mortgage loans are included in the Pass categories unless a specific action, such as bankruptcy, repossession, or death occurs to raise awareness of a possible credit event. The Bank’s Commercial Loan Officers are responsible for the timely and accurate risk rating of the loans in their portfolios at origination and on an ongoing basis. The Bank’s Commercial Loan Officers perform an annual review of all commercial relationships $250,000 or greater. Confirmation of the appropriate risk grade is included in the review on an ongoing basis. The Bank engages an external consultant to conduct loan reviews on at least a semi-annual basis. Generally, the external consultant reviews commercial relationships greater than $500,000 and/or all criticized relationships. Detailed reviews, including plans for resolution, are performed on loans classified as Substandard on a quarterly basis. Loans in the Special Mention and Substandard categories that are collectively evaluated for impairment are given separate consideration in the determination of the allowance.



The following tables present the classes of the loan portfolio summarized by the aggregate Pass and the criticized categories of Special Mention, Substandard and Doubtful within the internal risk rating system as of March 31, 2014 and September 30, 2013 (in thousands):

Our allowance for loan losses is maintained at a level necessary to absorb loan losses that are both probable and reasonably estimable. Management, in determining the allowance for loan losses, considers the losses inherent in its loan portfolio and changes in the nature and volume of loan activities, along with the general economic and real estate market conditions. Our allowance for loan losses consists of two elements: (1) an allocated allowance, which comprises allowances established on specific loans and class allowances based on historical loss experience and current trends, and (2) an allocated allowance based on general economic conditions and other risk factors in our markets and portfolios. We maintain a loan review system, which allows for a periodic review of our loan portfolio and the early identification of potential impaired loans. Such system takes into consideration, among other things, delinquency status, size of loans, type and market value of collateral and financial condition of the borrowers. General loan loss allowances are based upon a combination of factors including, but not limited to, actual loan loss experience, composition of the loan portfolio, current economic conditions, management’s judgment and losses which are probable and reasonably estimable. The allowance is increased through provisions charged against current earnings and recoveries of previously charged-off loans. Loans that are determined to be uncollectible are charged against the allowance. While management uses available information to recognize probable and reasonably estimable loan losses, future loss provisions may be necessary, based on changing economic conditions. Payments received on impaired loans generally are either applied against principal or reported as interest income, according to management’s judgment as to the collectability of principal. The allowance for loan losses as of March 31, 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 our allowance for loan losses. The banking regulators may require that we recognize additions to the allowance based on its analysis and review of information available to it at the time of its examination.

Management reviews the loan portfolio on a quarterly basis using a defined, consistently applied process in order to make appropriate and timely adjustments to the ALL. When information confirms all or part of specific loans to be uncollectible, these amounts are promptly charged off against the ALL.



The following tables summarize changes in the primary segments of the ALL for the three and six month periods ending March 31, 2014:

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 loans, home equity loans and lines of credit segments for the six month period ending March 31, 2014 due to increased charge off activity and impairment evaluations in those segments. Despite the above allocations, the allowance for loan losses is general in nature and is available to absorb losses from any loan segment.

	The Company maintains the ESSA Bancorp, Inc. 2007 Equity Incentive Plan (the “Plan”). The Plan provides for a total of 2,377,326 shares of common stock for issuance upon the grant or exercise of awards. Of the shares available under the Plan, 1,698,090 may be issued in connection with the exercise of stock options and 679,236 may be issued as restricted stock. The Plan allows for the granting of non-qualified stock options (“NSOs”), incentive stock options (“ISOs”), and restricted stock. Options are granted at no less than the fair value of the Company’s common stock on the date of the grant.

	Certain officers, employees and outside directors were granted in aggregate 1,140,469 NSOs; 317,910 ISOs; and 590,320 shares of restricted stock on May 23, 2008. Certain officers were granted in aggregate 30,000 shares of restricted stock on April 1, 2013. 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 vest over a five-year service period and expire ten years after grant date. The Company recognizes compensation expense for the fair values of these awards, which vest on a straight-line basis over the requisite service period of the awards.

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



	For the six months ended March 31, 2014 and 2013, the Company recorded $122,000 and $1.1 million of share-based compensation expense, respectively, comprised of restricted stock expense of $122,000 for the March 31, 2014 period and stock option expense of $344,000 and restricted stock expense of $711,000 for the March 31, 2013 period. Expected future compensation expense relating to the 13,334 restricted shares at March 31, 2014, is $97,000 over the remaining vesting period of 0.5 years.

	The following is a summary of the Company’s stock option activity and related information for its option grants for the six month period ended March 31, 2014.

	11	Fair Value Measurement

	The following disclosures show the hierarchal disclosure framework associated within the level of pricing observations utilized in measuring assets and liabilities at fair value. The definition of fair value maintains the exchange price notion in earlier definitions of fair value but focuses on the exit price of the asset or liability. The exit price is the price that would be received to sell the asset or paid to transfer the liability adjusted for certain inherent risks and restrictions. Expanded disclosures are also required about the use of fair value to measure assets and liabilities.



	The following table presents information about the Company’s securities, other real estate owned and impaired loans measured at fair value as of March 31, 2014 and September 30, 2013 and indicates the fair value hierarchy of the valuation techniques utilized by the Bank to determine such fair value:

Each financial asset and liability is identified as having been valued according to a specified level of input, 1, 2 or 3. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Bank has the ability to access at the measurement date. Fair values determined by Level 2 inputs utilize inputs other than quoted prices included in Level 1 that are observable for the asset, either directly or indirectly. Level 2 inputs include quoted prices for similar assets in active markets, and inputs other than quoted prices that are observable for the asset or liability. Level 3 inputs are unobservable inputs for the asset, and include situations where there is little, if any, market activity for the asset or liability. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy, within which the fair value measurement in its entirety falls, has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset.

The measurement of fair value should be consistent with one of the following valuation techniques: market approach, income approach, and/or cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities (including a business). For example, valuation techniques consistent with the market approach often use market multiples derived from a set of comparables. Multiples might lie in ranges with a different multiple for each comparable. The selection of where within the range the appropriate multiple falls requires judgment, considering factors specific to the measurement (qualitative and quantitative). Valuation techniques consistent with the market approach include matrix pricing. Matrix pricing is a mathematical technique used principally to value debt securities without relying exclusively on quoted prices for the specific securities, but rather by relying on a security’s relationship to other benchmark quoted securities. Most of the securities classified as available for sale are reported at fair value utilizing Level 2 inputs. For these securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quoted market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. Securities reported at fair value utilizing Level 1 inputs are limited to actively traded equity securities whose market price is readily available from the New York Stock Exchange or the NASDAQ exchange. 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 March 31, 2014, 233 impaired loans with a carrying value of $38.5 million were reduced by specific valuation allowance totaling $919,000 resulting in a net fair value of $37.6 million based on Level 3 inputs. At September 30, 2013, 233 impaired loans with a carrying value of $36.4 million were reduced by a specific valuation totaling $819,000 resulting in a net fair value of $37.6 million based on Level 3 inputs.

The following table presents additional quantitative information about assets measured at fair value on a nonrecurring basis and for which the Company has utilized Level 3 inputs to determine fair value:

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 Bank, are not considered financial instruments but have value, this fair value of financial instruments would not represent the full market value of the Company.

The Company employed simulation modeling in determining the fair value of financial instruments for which quoted market prices were not available based upon the following assumptions:

Cash and Cash Equivalents, Accrued Interest Receivable, Short-Term Borrowings, Advances by Borrowers for Taxes and Insurance, and Accrued Interest Payable

The fair value approximates the current book value.

Bank-Owned Life Insurance

The fair value is equal to the cash surrender value of the Bank-owned life insurance.

Investment and Mortgage-Backed Securities Available for Sale and FHLB Stock

The fair value of investment and mortgage-backed securities available for sale is equal to the available quoted market price. If no quoted market price is available, fair value is estimated using the quoted market price for similar securities. Since the FHLB stock is not actively traded on a secondary market and held exclusively by member financial institutions, the fair market value approximates the carrying amount.

Loans Receivable

The fair values of loans are estimated using discounted cash flow analyses, using market rates at the balance sheet date that reflect the credit and interest rate-risk inherent in the loans. Projected future cash flows are calculated based upon contractual maturity or call dates, projected repayments and prepayments of principal. Generally, for variable rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values.

Mortgage Servicing Rights

The Company utilizes a third party provider to estimate the fair value of certain loan servicing rights. Fair value for the purpose of this measurement is defined as the amount at which the asset could be exchanged in a current transaction between willing parties, other than in a forced liquidation.

Deposit Liabilities

The fair values disclosed for demand, savings, and money market deposit accounts are valued at the amount payable on demand as of quarter-end. Fair values for time deposits are estimated using a discounted cash flow calculation that applies contractual costs currently being offered in the existing portfolio to current market rates being offered for deposits of similar remaining maturities.

Other Borrowings

Fair values for other borrowings are estimated using a discounted cash flow calculation that applies contractual costs currently being offered in the existing portfolio to current market rates being offered for other borrowings of similar remaining maturities.

Commitments to Extend Credit

These financial instruments are generally not subject to sale, and fair values are not readily available. The carrying value, represented by the net deferred fee arising from the unrecognized commitment, and the fair value, determined by discounting the remaining contractual fee over the term of the commitment using fees currently charged to enter into similar agreements with similar credit risk, are not considered material for disclosure.

Acquisition of FNCB Branch	'
	13	ACQUISITION OF FNCB BRANCH

	On January 24, 2014, the Company closed on a purchase transaction pursuant to which ESSA Bancorp, Inc. acquired 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 the 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.



	The following condensed statement reflects the values assigned to FNCB’s net assets as of the acquisitions date:



	Net cash received		$	4,640

	Net assets 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.

Accounting Changes And Error Corrections [Abstract]	'
Financial Services Investment Companies	'
Financial Services Investment Companies	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. 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 ASU is not expected to have a significant impact on the Company’s financial statements.
Income Taxes	'
Income Taxes	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 ASU is not expected to have a significant impact on the Company’s financial statements.
Investments	'
Investments	In January 2014, FASB issued ASU 2014-01, Investments – Equity Method and Join 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 ASU is not expected to have a significant impact on the Company’s financial statements.
Receivables Troubled Debt Restructurings	'
Receivables Troubled Debt Restructurings	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 ASU is not expected to have a significant impact on the Company’s financial statements.
