Basis of Presentation	'
	-1	Basis of Presentation
	The accompanying unaudited consolidated statement of financial condition as of June 30, 2013 was derived from the audited consolidated financial statements of Greene County Bancorp, Inc. (the “Company”) and its wholly owned subsidiary, The Bank of Greene County (the “Bank”) and the Bank’s wholly owned subsidiary, Greene County Commercial Bank and Greene Property Holdings, Ltd.  The consolidated financial statements at and for the three months ended September 30, 2013 and 2012 are unaudited.
	The financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X.  Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements.  To the extent that information and notes required by GAAP for complete financial statements are contained in or are consistent with the audited financial statements incorporated by reference to Greene County Bancorp, Inc.’s Annual Report on Form 10-K for the year ended June 30, 2013, such information and notes have not been duplicated herein.  In the opinion of management, all adjustments (consisting of only normal recurring items) necessary for a fair presentation of the financial position and results of operations and cash flows at and for the periods presented have been included.   Amounts in the prior year’s consolidated financial statements have been reclassified whenever necessary to conform to the current year’s presentation.  These reclassifications, if any, had no effect on net income or retained earnings as previously reported.  All material inter-company accounts and transactions have been eliminated in the consolidation. The results of operations and other data for the three months ended September 30, 2013 are not necessarily indicative of results that may be expected for the entire fiscal year ending June 30, 2014.   These consolidated financial statements consider events that occurred through the date the consolidated financial statements were issued.
	CRITICAL ACCOUNTING POLICIES
	Greene County Bancorp, Inc.’s critical accounting policies relate to the allowance for loan losses and the evaluation of securities for other-than-temporary impairment.  The allowance for loan losses is based on management’s estimation of an amount that is intended to absorb losses in the existing loan portfolio.  The allowance for loan losses is established through a provision for loan losses based on management’s evaluation of the risk inherent in the loan portfolio, the composition of the portfolio, specific impaired loans and current economic conditions.  Such evaluation, which includes a review of all loans for which full collectibility may not be reasonably assured, considers among other matters, the estimated net realizable value or the fair value of the underlying collateral, economic conditions, historical loan loss experience, management’s estimate of probable credit losses and other factors that warrant recognition in providing for the allowance of loan losses.  However, this evaluation involves a high degree of complexity and requires management to make subjective judgments that often require assumptions or estimates about highly uncertain matters.  This critical accounting policy and its application are periodically reviewed with the Audit Committee and the Board of Directors.
	Securities are evaluated for other-than-temporary impairment by performing periodic reviews of individual securities in the investment portfolio.  Greene County Bancorp, Inc. makes an assessment to determine whether there have been any events or economic circumstances to indicate that a security on which there is an unrealized loss is impaired on an other-than-temporary basis.  The Company considers many factors, including the severity and duration of the impairment; the intent and ability of the Company to hold the security for a period of time sufficient for a recovery in value; recent events specific to the issuer or industry; and for debt securities, intent to sell the security, the likelihood to be required to sell the security before it recovers the entire amortized cost, external credit ratings and recent downgrades.  The Company is required to record other-than-temporary impairment charges through earnings, if it has the intent to sell, or will more likely than not be required to sell an impaired debt security before a recovery of its amortized cost basis.  In addition, the Company is required to record other-than-temporary impairment charges through earnings for the amount of credit losses, regardless of the intent or requirement to sell.  Credit loss is measured as the difference between the present value of an impaired debt security’s cash flows and its amortized cost basis.  Non-credit related impairment must be recorded as decreases to accumulated other comprehensive income as long as the Company has no intent or requirement to sell an impaired security before a recovery of amortized cost basis.

Use of Estimates [Abstract]	'
Use of Estimates	'
	-3	Use of Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could materially differ from those estimates.  Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses and the assessment of other-than-temporary security impairment.
	While management uses available information to recognize losses on loans, future additions to the allowance for loan losses (the “Allowance”) may be necessary, based on changes in economic conditions, asset quality or other factors.  In addition, various regulatory authorities, as an integral part of their examination process, periodically review the Allowance.  Such authorities may require the Company to recognize additions to the Allowance based on their judgments of information available to them at the time of their examination.
	Greene County Bancorp, Inc. makes an assessment to determine whether there have been any events or economic circumstances to indicate that a security on which there is an unrealized loss is impaired on an other-than-temporary basis.  The Company considers many factors including the severity and duration of the impairment; the intent and ability of the Company to hold the security for a period of time sufficient for a recovery in value; recent events specific to the issuer or industry; and for debt securities, intent to sell the security, whether it is more likely than not we will be required to sell the security before recovery, whether loss of the entire amortized cost is expected, external credit ratings and recent downgrades.  Securities on which there is an unrealized loss that is deemed to be other-than-temporary are written down to fair value.

At September 30, 2013, there were 124 securities which have been in a continuous unrealized loss position for less than 12 months and 5 securities with a continuous unrealized loss position of more than 12 months.  When the fair value of a held to maturity or available for sale security is less than its amortized cost basis, an assessment is made as to whether other-than-temporary impairment (“OTTI”) is present.  The Company considers numerous factors when determining whether a potential OTTI exists and the period over which the debt security is expected to recover.  The principal factors considered are (1) the length of time and the extent to which the fair value has been less than the amortized cost basis, (2) the financial condition of the issuer (and guarantor, if any) and adverse conditions specifically related to the security, industry or geographic area, (3) failure of the issuer of the security to make scheduled interest or principal payments, (4) any changes to the rating of the security by a rating agency, and (5) the presence of credit enhancements, if any, including the guarantee of the federal government or any of its agencies.
For debt securities, OTTI is considered to have occurred if (1) the Company intends to sell the security, (2) it is more likely than not the Company will be required to sell the security before recovery of its amortized cost basis, or (3) if the present value of expected cash flows is not sufficient to recover the entire amortized cost basis.  In determining the present value of expected cash flows, the Company discounts the expected cash flows at the effective interest rate implicit in the security at the date of acquisition.  In estimating cash flows expected to be collected, the Company uses available information with respect to security prepayment speeds, default rates and severity.  In determining whether OTTI has occurred for equity securities, the Company considers the applicable factors described above and the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value.
For debt securities, credit-related OTTI is recognized in income while noncredit related OTTI on securities not expected to be sold is recognized in other comprehensive income (“OCI”).  Credit-related OTTI is measured as the difference between the present value of an impaired security’s expected cash flows and its amortized cost basis.  Noncredit-related OTTI is measured as the difference between the fair value of the security and its amortized cost less any credit-related losses recognized.  For securities classified as held to maturity, the amount of OTTI recognized in OCI is accreted to the credit-adjusted expected cash flow amounts of the securities over future periods.  For equity securities, the entire amount of OTTI is recognized in income.  Management evaluated securities considering the factors as outlined above, and based on this evaluation the Company does not consider these investments to be other-than-temporarily impaired at September 30, 2013.  Management believes that the reasons for the decline in fair value are due to interest rates and widening credit spreads at the end of the quarter.
During the quarters ended September 30, 2013 and 2012, there were no sales of securities and no gains or losses were recognized.  There was no other-than-temporary impairment loss recognized during the quarters ended September 30, 2013 and 2012.
The estimated fair values of debt securities at September 30, 2013, by contractual maturity are shown below.  Expected maturities may differ from contractual maturities, because issuers may have the right to call or prepay obligations with or without call or prepayment penalties.

As of September 30, 2013 and June 30, 2013, respectively, securities with an aggregate fair value of $193.2 million and $200.9 million were pledged as collateral for deposits in excess of FDIC insurance limits for various municipalities placing deposits with Greene County Commercial Bank.  As of September 30, 2013 and June 30, 2013, securities with an aggregate fair value of $5.2 million were pledged as collateral for potential borrowings at the Federal Reserve Bank discount window.  Greene County Bancorp, Inc. did not participate in any securities lending programs during the quarters ended September 30, 2013 or 2012.
Federal Home Loan Bank Stock
Federal law requires a member institution of the Federal Home Loan Bank (“FHLB”) system to hold stock of its district FHLB according to a predetermined formula.  This stock is restricted in that it can only be sold to the FHLB or to another member institution, and all sales of FHLB stock must be at par.  As a result of these restrictions, FHLB stock is carried at cost.  FHLB stock is held as a long-term investment and its value is determined based on the ultimate recoverability of the par value.  Impairment of this investment is evaluated quarterly and is a matter of judgment that reflects management’s view of the FHLB’s long-term performance, which includes factors such as the following:   its operating performance; the severity and duration of declines in the fair value of its net assets related to its capital stock amount; its commitment to make payments required by law or regulation and the level of such payments in relation to its operating performance; the impact of legislative and regulatory changes on the FHLB, and accordingly, on the members of the FHLB; and its liquidity and funding position.  After evaluating these considerations, Greene County Bancorp, Inc. concluded that the par value of its investment in FHLB stock will be recovered and, therefore, no other-than-temporary impairment charge was recorded during the fiscal quarters ended September 30, 2013 or 2012.

	-5	Credit Quality of Loans and Allowance for Loan Losses
	Management closely monitors the quality of the loan portfolio and has established a loan review process designed to help grade the quality and profitability of the Company’s loan portfolio. The credit quality grade helps management make a consistent assessment of each loan relationship’s credit risk. Consistent with regulatory guidelines, The Bank of Greene County provides for the classification of loans considered being of lesser quality.  Such ratings coincide with the "Substandard," "Doubtful" and "Loss" classifications used by federal regulators in their examination of financial institutions. Generally, an asset is considered Substandard if it is inadequately protected by the current net worth and paying capacity of the obligors and/or the collateral pledged. Substandard assets include those characterized by the distinct possibility that the insured financial institution will sustain some loss if the deficiencies are not corrected. Assets classified as Doubtful have all the weaknesses inherent in assets classified Substandard with the added characteristic that the weaknesses present make collection or liquidation in full, on the basis of currently existing facts, highly questionable and improbable. Assets classified as Loss are those considered uncollectible and of such little value that their continuance as assets without the establishment of a full loss reserve and/or charge-off is not warranted. Assets that do not currently expose the insured financial institutions to sufficient risk to warrant classification in one of the aforementioned categories but otherwise possess weaknesses are designated "Special Mention."   Management also maintains a listing of loans designated “Watch.” These loans represent borrowers with declining earnings, strained cash flow, increasing leverage and/or weakening market fundamentals that indicate above average risk.
	When The Bank of Greene County classifies problem assets as either Substandard or Doubtful, it generally establishes a specific valuation allowance or "loss reserve" in an amount deemed prudent by management.  General allowances represent loss allowances that have been established to recognize the inherent risk associated with lending activities, but which, unlike specific allowances, have not been allocated to particular loans.  When The Bank of Greene County identifies problem loans as being impaired, it is required to evaluate whether the Bank will be able to collect all amounts due either through repayments or the liquidation of the underlying collateral.  If it is determined that impairment exists, the Bank is required either to establish a specific allowance for losses equal to the amount of impairment of the assets, or to charge-off such amount.  Regulatory agencies may require The Bank of Greene County to recognize additions to the allowance based on their judgment about information available to them at the time of their examination.  The Bank of Greene County reviews its portfolio monthly to determine whether any assets require classification in accordance with applicable regulations.
	The Bank primarily has four segments within its loan portfolio that it considers when measuring credit quality: real estate loans, home equity, consumer installment and commercial loans.  The real estate portfolio consists of residential, nonresidential, and construction loan classes. The inherent risk within the loan portfolio varies depending upon each of these loan types.
	The Bank of Greene County’s primary lending activity is the origination of residential mortgage loans, including home equity loans, which are collateralized by residences.   Generally, residential mortgage loans are made in amounts up to 80 % of the appraised value of the property.  However, The Bank of Greene County will originate residential mortgage loans with loan-to-value ratios of up to 95%, with private mortgage insurance.  In the event of default by the borrower, The Bank of Greene County will acquire and liquidate the underlying collateral.    By originating the loan at a loan-to-value ratio of 80% or less or obtaining private mortgage insurance, The Bank of Greene County limits its risk of loss in the event of default.  However, the market values of the collateral may be adversely impacted by declines in the economy.  Home equity loans may have an additional inherent risk if The Bank of Greene County does not hold the first mortgage.  The Bank of Greene County may stand in a secondary position in the event of collateral liquidation resulting in a greater chance of insufficiency to meet all obligations.
	Construction lending generally involves a greater degree of risk than other residential mortgage lending.  The repayment of the construction loan is, to a great degree, dependent upon the successful and timely completion of the construction of the subject property within specified cost limits.  The Bank of Greene County completes inspections during the construction phase prior to any disbursements.  The Bank of Greene County limits its risk during the construction as disbursements are not made until the required work for each advance has been completed.  Construction delays may further impair the borrower's ability to repay the loan.
	Loans collateralized by nonresidential mortgage loans, and multi-family loans, such as apartment buildings generally are larger than residential loans and involve a greater degree of risk. Commercial mortgage loans often involve large loan balances to single borrowers or groups of related borrowers. Payments on these loans depend to a large degree on the results of operations and management of the properties or underlying businesses, and may be affected to a greater extent by adverse conditions in the real estate market or the economy in general. Accordingly, the nature of nonresidential mortgage loans makes them more difficult for management to monitor and evaluate.
	Consumer loans generally have shorter terms and higher interest rates than residential mortgage loans. In addition, consumer loans expand the products and services offered by The Bank of Greene County to better meet the financial services needs of its customers.  Consumer loans generally involve greater credit risk than residential mortgage loans because of the difference in the nature of the underlying collateral.  Repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment of the outstanding loan balance because of the greater likelihood of damage, loss or depreciation in the underlying collateral. The remaining deficiency often does not warrant further substantial collection efforts against the borrower beyond obtaining a deficiency judgment. In addition, consumer loan collections depend on the borrower's personal financial stability.  Furthermore, the application of various federal and state laws, including federal and state bankruptcy and insolvency laws, may limit the amount that can be recovered on such loans.
	Commercial lending generally involves greater risk than residential mortgage lending and involves risks that are different from those associated with residential and nonresidential mortgage lending. Real estate lending is generally considered to be collateral-based, with loan amounts based on fixed loan-to-collateral values, and liquidation of the underlying real estate collateral is viewed as the primary source of repayment in the event of borrower default. Although commercial loans may be collateralized by equipment or other business assets, the liquidation of collateral in the event of a borrower default is often an insufficient source of repayment because equipment and other business assets may be obsolete or of limited use, among other things. Accordingly, the repayment of a commercial loan depends primarily on the creditworthiness of the borrower (and any guarantors), while liquidation of collateral is a secondary and often insufficient source of repayment.

	The Company had no loans classified Doubtful or Loss at September 30, 2013 or June 30, 2013.
	Nonaccrual Loans
	Management places loans on nonaccrual status once the loans have become 90 days or more delinquent or sooner if there is a significant reason for management to believe the collectability is questionable and, therefore, interest on the loan will no longer be recognized on an accrual basis.  Nonaccrual is defined as a loan in which collectability is questionable and therefore interest on the loan will no longer be recognized on an accrual basis.  A loan is not placed back on accrual status until the borrower has demonstrated the ability and willingness to make timely payments on the loan.    A loan does not have to be 90 days delinquent in order to be classified as nonaccrual.   Nonaccrual loans consisted primarily of loans secured by real estate at September 30, 2013 and June 30, 2013.  While the Bank makes every reasonable effort to work with the borrowers to collect amounts due, the number of loans in process of foreclosure has grown substantially over the past several years.  This growth has been the result of adverse changes within the economy and increases in local unemployment.   The growth is also due in part to the extended length of time required to meet all of the legal requirements mandated by New York State law prior to a foreclosure sale, which may be in excess of two years.   Loans on nonaccrual status totaled $7.4 million at September 30, 2013 of which $5.4 million were in the process of foreclosure.  Included in nonaccrual loans were $1.5 million of loans which were less than 90 days past due at September 30, 2013, but have a recent history of delinquency greater than 90 days past due.   These loans will be returned to accrual status once they have demonstrated a history of timely payments.  Included in total loans past due were $1.3 million of loans which were making payments pursuant to forbearance agreements.  Under the forbearance agreements, the customers have made arrangements with the Bank to bring the loans current over a specified period of time (resulting in an insignificant delay in repayment).  During this term of the forbearance agreement, the Bank has agreed not to continue foreclosure proceedings.  Loans on nonaccrual status totaled $6.3 million at June 30, 2013 of which $4.9 million were in the process of foreclosure.  Included in nonaccrual loans, were $781,000 of loans which were less than 90 days past due at June 30, 2013, but have a recent history of delinquency greater than 90 days past due.

	Past due loans as of June 30, 2013 have been reclassified to exclude loans on non-accrual but less than 30 days delinquent.  These loans are still included in loans on non-accrual due to a recent history of delinquency greater than 90 days past due.  These loans will be returned to accrual status once they have demonstrated a history of timely payments.
	The Bank of Greene County had accruing loans delinquent more than 90 days as of September 30, 2013 totaling $555,000 and had accruing loans delinquent more than 90 days as of June 30, 2013 totaling $559,000.    The loans delinquent more than 90 days and accruing consist of loans that are well collateralized and the borrowers have demonstrated the ability and willingness to pay.  The borrower has made arrangements with the Bank to bring the loan current within a specified time period and has made a series of payments as agreed.

Impaired Loan Analysis
The Company identifies impaired loans and measures the impairment in accordance with Financial Accounting Statndards Board (“FASB”) Accounting Standards Codification (“ASC”)  subtopic “Receivables – Loan Impairment.”  Management may consider a loan impaired once it is classified as nonaccrual and when it is probable that the borrower will be unable to repay the loan according to the original contractual terms of the loan agreement or the loan is restructured in a troubled debt restructuring.  It should be noted that management does not evaluate all loans individually for impairment.  The Bank of Greene County considers residential mortgages, home equity loans, smaller commercial loans and installment loans as small, homogeneous loans, which are evaluated for impairment collectively based on historical loan experience and other factors.  In contrast, large commercial mortgage, construction, multi-family and commercial loans are viewed individually and considered impaired if it is probable that The Bank of Greene County will not be able to collect scheduled payments of principal and interest when due, according to the contractual terms of the loan agreement.  The measurement of impaired loans is generally based on the fair value of the underlying collateral.  The majority of The Bank of Greene County loans, including most nonaccrual loans, are small homogenous loan types adequately supported by collateral.  Management considers the payment status of loans in the process of evaluating the adequacy of the allowance for loan losses among other factors.  Loans that are either delinquent a minimum of 60 days or are on nonaccrual status, and are not individually evaluated for impairment, are either designated as Special Mention or Substandard, and the allocation of the allowance for loan loss is based upon the risk associated with such designation.  Loans that have been modified as a troubled debt restructuring are included in impaired loans.  The measurement of impairment is generally based on the discounted cash flows based on the original rate of the loan before the restructuring, unless it is determined that the restructured loan is collateral dependent.  If the restructured loan is deemed to be collateral dependent, impairment is based on the fair value of the underlying collateral.

These loans have been classified as troubled debt restructurings due to concessions granted to the debtors that The Bank of Greene County would not otherwise consider as a result of financial difficulties of the borrowers.  For these loans, concessions consisted of any combination of the following: additional funds were advanced, the interest rate was reduced and/or the term extended. If the borrower performs under the terms of the modification, and the ultimate collectability of all amounts contractually due under the modified terms is not in doubt, these loans will be returned to accrual status.   These loans identified as a troubled debt restructuring have been evaluated for impairment and the impact to the allowance for loan loss was immaterial.
The Company did not modify any loans that would be classified as troubled debt restructurings during the quarter ended September 30, 2012.

The allowance for loan losses is established through a provision for loan losses based on management’s evaluation of the losses inherent in the loan portfolio, the composition of the loan portfolio, specific impaired loans and current economic conditions.  Such evaluation, which includes a review of certain identified loans on which full collectability may not be reasonably assured, considers among other matters, the estimated net realizable value or the fair value of the underlying collateral, economic conditions, payment status of the loan, historical loan loss experience and other factors that warrant recognition in providing for the loan loss allowance.  In addition, various regulatory agencies, as an integral part of their examination process, periodically review The Bank of Greene County’s allowance for loan losses.  Such agencies may require The Bank of Greene County to recognize additions to the allowance based on their judgment about information available to them at the time of their examination.  The Bank of Greene County considers residential mortgages, home equity loans and installment loans to customers as small, homogeneous loans, which are evaluated for impairment collectively based on historical loss experience.  Commercial mortgage and business loans are viewed individually and considered impaired if it is probable that The Bank of Greene County will not be able to collect scheduled payments of principal and interest when due, according to the contractual terms of the loan agreements.  The measurement of impaired loans is generally based on the fair value of the underlying collateral.  The allowance for loan losses is increased by a provision for loan losses (which results in a charge to expense) and recoveries of loans previously charged off and is reduced by charge-offs. Generally, consumer loans and smaller business loans (not secured by real estate) in excess of 90 days are charged-off against the allowance for loan losses, unless equitable arrangements are made.   For loans secured by real estate, a charge-off is recorded when it is determined that the collection of all or a portion of a loan may not be collected and the amount of that loss can be reasonably estimated.
The following tables set forth the activity and allocation of the allowance for loan losses by loan category during and at the periods indicated.  The allowance is allocated to each loan category based on historical loss experience and economic conditions.

Fair Value Measurements and Fair Value of Financial Instruments	'
	-6	Fair Value Measurements and Fair Value of Financial Instruments
	Management uses its best judgment in estimating the fair value of the Company’s financial instruments; however, there are inherent weaknesses in any estimation technique.  Therefore, for substantially all financial instruments, the fair value estimates herein are not necessarily indicative of the amounts the Company could have realized in a sale transaction on the dates indicated.  The estimated fair value amounts have been measured as of September 30, 2013 and June 30, 2013 and have not been re-evaluated or updated for purposes of these consolidated financial statements subsequent to those respective dates.  As such, the estimated fair values of these financial instruments subsequent to the respective reporting dates may be different than the amounts reported at each period-end.
	The following information should not be interpreted as an estimate of the fair value of the entire Company since a fair value calculation is only provided for a limited portion of the Company’s assets and liabilities.  Due to a wide range of valuation techniques and the degree of subjectivity used in making the estimates, comparisons between the Company’s disclosures and those of other companies may not be meaningful.
	The FASB ASC Topic on “Fair Value Measurement” established a fair value hierarchy that prioritized the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows:
	Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.
	Level 2: Quoted prices in markets that are not active, or inputs that are observable either directly or indirectly, for substantially the full term of the asset or liability.
	Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported with little or no market activity).
	An asset’s or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.
	For assets measured at fair value on a recurring basis, the fair value measurements by level within the fair value hierarchy used are as follows:
						Fair Value Measurements Using

	Securities available for sale		$	69,644		$	5,345			$	64,299			$	-
	Certain investments that are actively traded and have quoted market prices have been classified as Level 1 valuations.  Other available-for-sale investment securities have been valued by reference to prices for similar securities or through model-based techniques in which all significant inputs are observable and, therefore, such valuations have been classified as Level 2.
	In addition to disclosures of the fair value of assets on a recurring basis, FASB ASC Topic on “Fair Value Measurement” requires disclosures for assets and liabilities measured at fair value on a nonrecurring basis, such as impaired assets, in the period in which a re-measurement at fair value is performed.  Loans are generally not recorded at fair value on a recurring basis. Periodically, the Company records nonrecurring adjustments to the carrying value of loans based on fair value measurements for partial charge-offs of the uncollectible portions of those loans. Nonrecurring adjustments also include certain impairment amounts for collateral-dependent loans calculated as required by the “Receivables –Loan Impairment” subtopic of the FASB ASC when establishing the allowance for credit losses.  Impaired loans are those loans for which the Company has re-measured impairment generally based on the fair value of the underlying collateral supporting the loan and, as a result, the carrying value of the loan less the calculated valuation amount may not necessarily represent the actual fair value of the loan. Real estate collateral is typically valued using independent appraisals or other indications of value based on recent comparable sales of similar properties or assumptions generally observable in the marketplace and the related nonrecurring fair value measurement adjustments have generally been classified as Level 3. Estimates of fair value used for other collateral supporting commercial loans generally are based on assumptions not observable in the marketplace and therefore such valuations have been classified as Level 3.  The Company has also re-measured impairment based on the discounted cash flows for those loans that have been modified as a troubled-debt restructuring.  The cashflows of the restructured debt have been discounted by the original interest rate prior to the restructuring of the loan to establish the fair value and is therefore classified as Level 3.

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

		-1	Fair value is generally determined through independent third-party appraisals of the underlying collateral, which generally includes various Level 3 inputs which are not observable.
		-2	Appraisals may be adjusted downwards by management for qualitative factors such as economic conditions.  Higher downward adjustments are caused by negative changes to the collateral or conditions in the real estate market, actual offers or sales contracts received or age of the appraisal.
		-3	Appraisals may be adjusted downwards by management for qualitative factors such as the estimated costs to liquidate the collateral.
	At September 30, 2013, loans subject to nonrecurring fair value measurement had a recorded investment of $5.7 million with related allowances of $1.1 million.  At June 30, 2013, loans subject to nonrecurring fair value measurement had a recorded investment of $6.6 million with related allowances of $1.2 million. No other financial assets or liabilities were re-measured during the year on a nonrecurring basis.
	The carrying amounts reported in the statements of financial condition for cash and cash equivalents, accrued interest receivable and accrued interest payable approximate their fair values.  Fair values of securities are based on quoted market prices (Level 1), where available, or matrix pricing (Level 2), which is a mathematical technique, used widely in the industry to value debt securities without relying exclusively on quoted market prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted prices.  The carrying amount of Federal Home Loan Bank stock approximates fair value due to its restricted nature.  Fair values for variable rate loans that reprice frequently, with no significant credit risk, are based on carrying value.  Fair value for fixed rate loans are estimated using discounted cash flows and interest rates currently being offered for loans with similar terms to borrowers of similar credit quality.  Fair values disclosed for demand and savings deposits are equal to carrying amounts at the reporting date.  The carrying amounts for variable rate money market deposits approximate fair values at the reporting date.  Fair values for fixed rate certificates of deposit are estimated using discounted cash flows and interest rates currently being offered in the market on similar certificates.  Fair value for Federal Home Loan Bank long term borrowings are estimated using discounted cash flows and interest rates currently being offered on similar borrowings.  The carrying value of short-term Federal Home Loan Bank borrowings approximates its fair value.
	The fair value of commitments to extend credit is estimated based on an analysis of the interest rates and fees currently charged to enter into similar transactions, considering the remaining terms of the commitments and the credit-worthiness of the potential borrowers.  At September 30, 2013 and June 30, 2013, the estimated fair values of these off-balance sheet financial instruments were immaterial, and are therefore excluded from the table below.

	Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding during the period.  Diluted earnings per share is computed in a manner similar to that of basic earnings per share except that the weighted-average number of common shares outstanding is increased to include the number of incremental common shares that would have been outstanding under the treasury stock method if all potentially dilutive common shares (such as stock options) issued became vested during the period.  There were no anti-dilutive securities or contracts outstanding during the quarters ended September 30, 2013 and 2012.

	On July 16, 2013, the Board of Directors declared a cash dividend for the quarter ended June 30, 2013 of $0.175 per share of Greene County Bancorp, Inc.’s common stock.  The dividend, which reflected an annual cash dividend rate of $0.70 cents per share, was unchanged from the dividend declared during the previous quarter. The dividend was payable to stockholders of record as of August 15, 2013, and was paid on August 30, 2013.  Historically, Greene County Bancorp, MHC has waived its right to receive dividends declared on its shares of the Company’s common stock.  As a result of the Dodd-Frank Act, the Federal Reserve Board adopted interim final regulations that impose significant conditions and restrictions on the ability of mutual holding companies to waive the receipt of dividends from their subsidiaries. Consequently, the MHC could not waive its right to receive dividends for the quarters ended September 30, 2012 and December 31, 2012.   The Federal Reserve Board requires that the MHC obtain approval of its members and receive the non-objection of the Federal Reserve Board to continue to waive dividends.  The approval to waive the dividend was obtained from the members of the MHC at the special meeting of members held on February 19, 2013, and the non-objection of the Federal Reserve Board for such dividend waiver was also received.  Accordingly, dividends were waived to Greene County Bancorp, MHC on April 1, 2013, May 31, 2013 and August 30, 2013.  Greene County Bancorp, MHC has the ability to waive dividends declared through February 19, 2014 without obtaining another vote of its members.  Greene County Bancorp, MHC’s ability to waive dividends beyond this date cannot be reasonably determined at this time.

	SERP
	The Board of Directors of The Bank of Greene County adopted The Bank of Greene County Supplemental Executive Retirement Plan (the “SERP Plan”), effective as of July 1, 2010. The SERP Plan will benefit certain key senior executives of the Bank who are selected by the Board to participate.
	The SERP Plan is intended to provide a benefit from the Bank upon retirement, death or disability or voluntary or involuntary termination of service (other than “for cause”). Accordingly, the SERP Plan obligates the Bank to make a contribution to each executive’s account on the first business day of each July and permits each executive to defer up to 50% of his or her base salary and 100% of his or her annual bonus to the SERP Plan, subject to the requirements of Section 409A of the Internal Revenue Code (“Code”). In addition, the Bank may, but is not required to, make additional discretionary contributions to the executives’ accounts from time to time. An executive becomes vested in the Bank’s contributions after 10 calendar years of service following the effective date of the SERP Plan, and is fully vested immediately for all deferral of salary and bonus. However, the Executive will vest in the present value of his or her account in the event of death, disability or a change in control of the Bank or the Company. In the event the executive is terminated involuntarily or resigns for good reason following a change in control, the present value of all remaining Bank contributions is accelerated and paid to the executive’s account, subject to potential reduction to avoid an excess parachute payment under Code Section 280G. In the event of the executive’s death, disability or termination within two years after a change in control, executive’s account will be paid in a lump sum to the executive or his beneficiary, as applicable. In the event executive is entitled to a benefit from the SERP Plan due to retirement or other termination of employment, the benefit will be paid in 10 annual installments.
	The net periodic pension costs related to the SERP Plan for the three months ended September 30, 2013 and 2012 were $26,000 and $22,000, respectively, consisting primarily of service costs and interest costs. The total liability for the SERP Plan was $707,000 and $595,200 as of September 30, 2013 and June 30, 2013, respectively.

There were no stock options granted during the three months ended September 30, 2013 or 2012.  All outstanding options were fully vested at September 30, 2013 or 2012.
	Phantom Stock Option Plan and Long-term Incentive Plan
	The Greene County Bancorp, Inc. 2011 Phantom Stock Option and Long-term Incentive Plan (the “Plan”), was adopted effective July 1, 2011, to promote the long-term financial success of the Company and its subsidiaries by providing a means to attract, retain and reward individuals who contribute to such success and to further align their interests with those of the Company’s shareholders.  The Plan is intended to provide benefits to employees and directors of the Company or any subsidiary as designated by the Compensation Committee of the Board of Directors of the Company (“Committee”).   A total of 900,000 phantom stock options will be available for awards under the Plan.  A phantom stock option represents the right to receive a cash payment on the date the award vests. The participant receives an amount equal to the positive difference between the strike price on the grant date and the book value of a share of the Company stock on the determination date, which is the last day of the plan year that is the end of the third plan year after the grant date of the award, unless otherwise specified by the Committee.  The strike price will be the price established by the Committee, which will not be less than 100% of the book value of a share on a specified date, as determined under generally accepted accounting principles (GAAP) as of the last day of the quarter ending on or immediately preceding the valuation date with adjustments made, in the sole discretion of the Committee, to exclude accumulated other comprehensive income (loss).  During the three months ended September 30, 2013 and 2012, phantom stock options totaling 227,330 and 243,473, respectively, were awarded under the plan.  The Company recognized $159,800 and $106,800 in compensation costs related to the phantom stock option plan during the three months ended September 30, 2013 and 2012, respectively.

	On October 15, 2013, the Board of Directors declared a cash dividend for the quarter ended September 30, 2013 of $0.175 per share on Greene County Bancorp, Inc.’s common stock.  The dividend reflects an annual cash dividend rate of $0.70 per share, which was the same as the dividend declared during the previous quarter.  The dividend will be payable to stockholders of record as of November 15, 2013, and will be paid on November 29, 2013.  Historically, the MHC has waived its right to receive dividends declared on its shares of the Company’s common stock.  The Federal Reserve Board has adopted interim final regulations that impose significant conditions and restrictions on the ability of mutual holding companies to waive the receipt of dividends from their subsidiaries, and as a result, the MHC was unable to waive its right to receive dividends paid on its shares on the Company’s common stock during the quarters ended September 30, 2012 and December 31, 2012. The MHC obtained approval of its members at the special meeting of members held on February 19, 2013 to waive the dividend, and received the non-objection of the Federal Reserve Board for such dividend waiver.  The MHC has thus far waived its right to receive dividends declared on its shares of the Company’s common stock in all periods subsequent to this approval and non-objection.  The MHC intends to waive its receipt of the dividend payable on November 29, 2013.

Basis of Presentation	'
	The accompanying unaudited consolidated statement of financial condition as of June 30, 2013 was derived from the audited consolidated financial statements of Greene County Bancorp, Inc. (the “Company”) and its wholly owned subsidiary, The Bank of Greene County (the “Bank”) and the Bank’s wholly owned subsidiary, Greene County Commercial Bank and Greene Property Holdings, Ltd.  The consolidated financial statements at and for the three months ended September 30, 2013 and 2012 are unaudited.
	The financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X.  Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements.  To the extent that information and notes required by GAAP for complete financial statements are contained in or are consistent with the audited financial statements incorporated by reference to Greene County Bancorp, Inc.’s Annual Report on Form 10-K for the year ended June 30, 2013, such information and notes have not been duplicated herein.  In the opinion of management, all adjustments (consisting of only normal recurring items) necessary for a fair presentation of the financial position and results of operations and cash flows at and for the periods presented have been included.   Amounts in the prior year’s consolidated financial statements have been reclassified whenever necessary to conform to the current year’s presentation.  These reclassifications, if any, had no effect on net income or retained earnings as previously reported.  All material inter-company accounts and transactions have been eliminated in the consolidation. The results of operations and other data for the three months ended September 30, 2013 are not necessarily indicative of results that may be expected for the entire fiscal year ending June 30, 2014.   These consolidated financial statements consider events that occurred through the date the consolidated financial statements were issued.
Allowance for Loan Losses	'
	Greene County Bancorp, Inc.’s critical accounting policies relate to the allowance for loan losses and the evaluation of securities for other-than-temporary impairment.  The allowance for loan losses is based on management’s estimation of an amount that is intended to absorb losses in the existing loan portfolio.  The allowance for loan losses is established through a provision for loan losses based on management’s evaluation of the risk inherent in the loan portfolio, the composition of the portfolio, specific impaired loans and current economic conditions.  Such evaluation, which includes a review of all loans for which full collectibility may not be reasonably assured, considers among other matters, the estimated net realizable value or the fair value of the underlying collateral, economic conditions, historical loan loss experience, management’s estimate of probable credit losses and other factors that warrant recognition in providing for the allowance of loan losses.  However, this evaluation involves a high degree of complexity and requires management to make subjective judgments that often require assumptions or estimates about highly uncertain matters.  This critical accounting policy and its application are periodically reviewed with the Audit Committee and the Board of Directors.
Securities	'
	Securities are evaluated for other-than-temporary impairment by performing periodic reviews of individual securities in the investment portfolio.  Greene County Bancorp, Inc. makes an assessment to determine whether there have been any events or economic circumstances to indicate that a security on which there is an unrealized loss is impaired on an other-than-temporary basis.  The Company considers many factors, including the severity and duration of the impairment; the intent and ability of the Company to hold the security for a period of time sufficient for a recovery in value; recent events specific to the issuer or industry; and for debt securities, intent to sell the security, the likelihood to be required to sell the security before it recovers the entire amortized cost, external credit ratings and recent downgrades.  The Company is required to record other-than-temporary impairment charges through earnings, if it has the intent to sell, or will more likely than not be required to sell an impaired debt security before a recovery of its amortized cost basis.  In addition, the Company is required to record other-than-temporary impairment charges through earnings for the amount of credit losses, regardless of the intent or requirement to sell.  Credit loss is measured as the difference between the present value of an impaired debt security’s cash flows and its amortized cost basis.  Non-credit related impairment must be recorded as decreases to accumulated other comprehensive income as long as the Company has no intent or requirement to sell an impaired security before a recovery of amortized cost basis.

Use of Estimates [Abstract]	'
Use of Estimates	'
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could materially differ from those estimates.  Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses and the assessment of other-than-temporary security impairment.
	While management uses available information to recognize losses on loans, future additions to the allowance for loan losses (the “Allowance”) may be necessary, based on changes in economic conditions, asset quality or other factors.  In addition, various regulatory authorities, as an integral part of their examination process, periodically review the Allowance.  Such authorities may require the Company to recognize additions to the Allowance based on their judgments of information available to them at the time of their examination.
Impaired Financing Receivable	'
	Greene County Bancorp, Inc. makes an assessment to determine whether there have been any events or economic circumstances to indicate that a security on which there is an unrealized loss is impaired on an other-than-temporary basis.  The Company considers many factors including the severity and duration of the impairment; the intent and ability of the Company to hold the security for a period of time sufficient for a recovery in value; recent events specific to the issuer or industry; and for debt securities, intent to sell the security, whether it is more likely than not we will be required to sell the security before recovery, whether loss of the entire amortized cost is expected, external credit ratings and recent downgrades.  Securities on which there is an unrealized loss that is deemed to be other-than-temporary are written down to fair value.

Federal Home Loan Bank Stock	'
	Federal Home Loan Bank Stock
	Federal law requires a member institution of the Federal Home Loan Bank (“FHLB”) system to hold stock of its district FHLB according to a predetermined formula.  This stock is restricted in that it can only be sold to the FHLB or to another member institution, and all sales of FHLB stock must be at par.  As a result of these restrictions, FHLB stock is carried at cost.  FHLB stock is held as a long-term investment and its value is determined based on the ultimate recoverability of the par value.  Impairment of this investment is evaluated quarterly and is a matter of judgment that reflects management’s view of the FHLB’s long-term performance, which includes factors such as the following:   its operating performance; the severity and duration of declines in the fair value of its net assets related to its capital stock amount; its commitment to make payments required by law or regulation and the level of such payments in relation to its operating performance; the impact of legislative and regulatory changes on the FHLB, and accordingly, on the members of the FHLB; and its liquidity and funding position.  After evaluating these considerations, Greene County Bancorp, Inc. concluded that the par value of its investment in FHLB stock will be recovered and, therefore, no other-than-temporary impairment charge was recorded during the fiscal quarters ended September 30, 2013 or 2012.

		-1	Fair value is generally determined through independent third-party appraisals of the underlying collateral, which generally includes various Level 3 inputs which are not observable.
		-2	Appraisals may be adjusted downwards by management for qualitative factors such as economic conditions.  Higher downward adjustments are caused by negative changes to the collateral or conditions in the real estate market, actual offers or sales contracts received or age of the appraisal.
		-3	Appraisals may be adjusted downwards by management for qualitative factors such as the estimated costs to liquidate the collateral.

[1]	Fair value is generally determined through independent third-party appraisals of the underlying collateral, which generally includes various Level 3 inputs which are not observable.
[2]	Appraisals may be adjusted downwards by management for qualitative factors such as economic conditions. Higher downward adjustments are caused by negative changes to the collateral or conditions in the real estate market, actual offers or sales contracts received or age of the appraisal.
[3]	Appraisals may be adjusted downwards by management for qualitative factors such as the estimated costs to liquidate the collateral.
