Basis of Presentation [Abstract]
Basis of Presentation	(1) Basis of Presentation Within the accompanying unaudited consolidated statement of financial condition, and related notes to the consolidated financial statements, June 30, 2016 data was derived from the audited consolidated financial statements of Greene County Bancorp, Inc. (the “Company”) and its wholly owned subsidiaries, The Bank of Greene County (the “Bank”) and Greene Risk Management, Inc., and the Bank’s wholly owned subsidiaries, Greene County Commercial Bank and Greene Property Holdings, Ltd. The consolidated financial statements at and for the three and six months ended December 31, 2016 and 2015 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, 2016, 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 and six months ended December 31, 2016, are not necessarily indicative of results that may be expected for the entire fiscal year ending June 30, 2017. 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 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 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, 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 equity security for a period of time sufficient for a recovery in value; recent events specific to the issuer or industry; and for debt securities, the 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 write-downs to fair value 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 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 through earnings.

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 December 31, 2016. 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. There were no transfers of securities available-for-sale to held-to-maturity during the three and six months ended December 31, 2016 or 2015. During the three and six months ended December 31, 2016 and 2015, there were no sales of securities and no gains or losses were recognized. There was no other-than-temporary impairment loss recognized during the three and six months ended December 31, 2016 and 2015. The estimated fair values of debt securities at December 31, 2016, 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.

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 three and six months ended December 31, 2016 or 2015.

Loans and Allowance for Loan Losses [Abstract]
Loans and Allowance for Loan Losses	(5) Loans and Allowance for Loan Losses Loan segments and classes at December 31, 2016 and June 30, 2016 are summarized as follows: (In thousands) December 31, 2016 June 30, 2016 Residential real estate: Residential real estate $ 238,431 $ 234,992 Residential construction and land 4,980 5,575 Multi-family 3,904 3,918 Commercial real estate: Commercial real estate 246,306 192,678 Commercial construction 25,651 20,159 Consumer loan: Home equity 20,660 20,893 Consumer installment 4,714 4,350 Commercial loans 56,236 48,725 Total gross loans 600,882 531,290 Allowance for loan losses (10,421 ) (9,485 ) Deferred fees and costs 866 959 Loans receivable, net $ 591,327 $ 522,764 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 Company 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. The Bank of Greene County’s determination as to the classification of its loans and the amount of its valuation allowance is subject to review by its regulatory agencies, which can order the establishment of additional general or specific loss allowances. 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: residential real estate loans, commercial real estate loans, consumer loans and commercial loans. The residential real estate portfolio consists of residential, construction, and multifamily loan classes. Commercial real estate loans consist of commercial real estate and commercial construction loan classes. Consumer loans consist of home equity loan and consumer installment 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 89.9% 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 95.0%, 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 89.9% 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 commercial real estate, and multi-family dwellings, such as apartment buildings generally are larger than residential loans and involve a greater degree of risk. Commercial real estate 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 commercial real estate 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 commercial real estate 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. Loan balances by internal credit quality indicator as of December 31, 2016 are shown below.

Nonaccrual Loans Management places loans on nonaccrual status once the loans have become 90 days or more delinquent. A nonaccrual loan 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 December 31, 2016 and June 30, 2016. Loans on nonaccrual status totaled $3.8 million at December 31, 2016, of which $1.5 million were in the process of foreclosure. At December 31, 2016, there were 12 residential loans in the process of foreclosure totaling $895,000. Included in nonaccrual loans were $1.9 million of loans which were less than 90 days past due at December 31, 2016, 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 $183,000 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 $3.3 million at June 30, 2016 of which $1.5 million were in the process of foreclosure. At June 30, 2016, there were nine residential loans in the process of foreclosure totaling $867,000. Included in nonaccrual loans were $1.9 million of loans which were less than 90 days past due at June 30, 2016, but have a recent history of delinquency greater than 90 days past due.

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.

There were no loans that had been modified as a troubled debt restructuring during the twelve months prior to June 30, 2016 or 2015 which have subsequently defaulted during the three and six months ended December 31, 2016 or 2015, respectively. Allowance for Loan Losses 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 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 smaller balance residential mortgages, home equity loans, commercial loans and installment loans to customers as small, homogeneous loans, which are evaluated for impairment collectively based on historical loss experience. Larger balance residential, 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 Bank of Greene County charges loans off against the allowance for credit losses when it becomes evident that a loan cannot be collected within a reasonable amount of time or that it will cost the Bank more than it will receive, and all possible avenues of repayment have been analyzed, including the potential of future cash flow, the value of the underlying collateral, and strength of any guarantors or co-borrowers. 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.

Fair Value Measurements and Fair Value of Financial Instruments [Abstract]
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 December 31, 2016 and June 30, 2016 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” 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 (In thousands) December 31, 2016 Quoted Prices In Active Markets For Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Assets: U.S. Government sponsored enterprises $ 4,746 $ - $ 4,746 $ - State and political subdivisions 54,297 - 54,297 - Mortgage-backed securities-residential 5,662 - 5,662 - Mortgage-backed securities-multi-family 18,009 - 18,009 - Asset-backed securities 4 4 - - Corporate debt securities 2,834 2,834 - - Equity securities 158 158 - - Securities available-for-sale $ 85,710 $ 2,996 $ 82,714 $ - Fair Value Measurements Using (In thousands) June 30, 2016 Quoted Prices In Active Markets For Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Assets: U.S. Government sponsored enterprises $ 4,891 $ - $ 4,891 $ - State and political subdivisions 60,499 - 60,499 - Mortgage-backed securities-residential 6,540 - 6,540 - Mortgage-backed securities-multi-family 23,879 - 23,879 - Asset-backed securities 5 5 - - Corporate debt securities 4,157 4,157 - - Equity securities 152 152 - - Securities available-for-sale $ 100,123 $ 4,314 $ 95,809 $ - 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” Receivables –Loan Impairment” Fair Value Measurements Using (In thousands) Recorded Investment Related Allowance Fair Value (Level 1) (Level 2) (Level 3) December 31, 2016 Impaired loans $ 1,422 $ 298 $ 1,124 $ - $ - $ 1,124 Foreclosed real estate 338 - 338 - - 338 June 30, 2016 Impaired loans $ 655 $ 164 $ 491 $ - $ - $ 491 Foreclosed real estate 370 - 370 - - 370 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: (Dollars in thousands) Fair Value Valuation Technique Unobservable Input Range Weighted Average December 31, 2016 Impaired Loans $ 1,124 Appraisal of collateral (1) Appraisal adjustments (2) 16.50%-42.52 % 26.73 % Liquidation expenses (3) 3.45%-8.35 % 6.25 % Foreclosed real estate 338 Appraisal of collateral (1) Appraisal adjustments (2) 0.00%-54.17 % 3.50 % Liquidation expenses (3) 0.42%-11.79 % 7.18 % June 30, 2016 Impaired loans $ 491 Appraisal of collateral (1) Appraisal adjustments (2) 0.00%-38.85 % 21.01 % Liquidation expenses (3) 0.00%-8.35 % 4.92 % Foreclosed real estate 370 Appraisal of collateral (1) Appraisal adjustments (2) 0.00%-54.17 % 8.83 % Liquidation expenses (3) 0.42%-12.67 % 7.81 % (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 are adjusted downwards by management for qualitative factors such as the estimated costs to liquidate the collateral. 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 December 31, 2016 and June 30, 2016, the estimated fair values of these off-balance sheet financial instruments were immaterial, and are therefore excluded from the table below.

Earnings Per Share [Abstract]
Earnings Per Share	(7) Earnings Per Share 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 three and six months ended December 31, 2016 and 2015. On February 17, 2016, the Company declared a 2-for-1 stock split on the Company’s common stock. The stock split was paid on March 15, 2016 to stockholders of record as of March 7, 2016.

Impact of Recent Accounting Pronouncements [Abstract]
Impact of Recent Accounting Pronouncements	(9) Impact of Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standard Update (“ASU) (ASU 2014-09) to amend its guidance on “Revenue from Contracts with Customers (Topic 606). The objective of the ASU is to align the recognition of revenue with the transfer of promised goods or services provided to customers in an amount that reflects the consideration which the entity expects to be entitled in exchange for those goods or services. This ASU will replace most existing revenue recognition guidance under GAAP when it becomes effective. In August, 2015, the FASB issued an amendment (ASU 2015-14) which defers the effective date of this new guidance by one year. More detailed implementation guidance on Topic 606 was issued in March 2016 (ASU 2016-08), April 2016 (ASU 2016-10) and May 2016 (ASU 2016-12), and the effective date and transition requirements for these ASUs are the same as the effective date and transition requirements of ASU 2014-09. The amendments in ASU 2014-09 are effective for public business entities for annual periods, beginning after December 15, 2017. The Company has not yet determined the effect of the standard on its ongoing financial reporting. In August 2014, the FASB issued an amendment (ASU 2014-14) to its guidance on “Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40)”. The objective of the ASU is to reduce the diversity in how creditors classify government-guaranteed mortgage loans, including FHA or VA guaranteed loans, upon foreclosure, to provide more decision-useful information about a creditor’s foreclosed mortgage loans that are expected to be recovered, at least in part, through government guarantees. 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, 2017. Public entities would be permitted to elect to early adopt for annual reporting periods beginning after December 15, 2016. The adoption of this guidance is not expected to have a material impact on our consolidated results of operations or financial position. In January 2015, the FASB issued an Update (ASU 2015-01) to its guidance on “Income Statement-Extraordinary and Unusual Items (Subtopic 225-20)”. The objective of the ASU is to simplify the income statement presentation by eliminating the concept of extraordinary items, and will align GAAP more closely with International Accounting Standards which prohibits the presentation and disclosure of extraordinary items. The amendments in this Update were effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. The adoption of this guidance did not have a material impact on our consolidated results of operations or financial position. In January 2016, the FASB issued an Update (ASU 2016-01) to its guidance on “Financial Instruments (Subtopic 825-10)”. This amendment addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. These amendments require equity securities to be measured at fair value with changes in the fair value to be recognized through net income. The amendments also simplify the impairment assessment of equity investments without readily determinable fair values by requiring assessment for impairment qualitatively at each reporting period. For public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption of the amendments in this Update is not permitted. The adoption of this guidance is not expected to have a material impact on our consolidated results of operations or financial position. In February 2016, the FASB issued an Update (ASU 2016-02) to its guidance on “Leases (Topic 842)”. The new leases standard applies a right-of-use (ROU) model that requires a lessee to record, for all leases with a lease term of more than 12 months, an asset representing its right to use the underlying asset and a liability to make lease payments. For leases with a term of 12 months or less, a practical expedient is available whereby a lessee may elect, by class of underlying asset, not to recognize an ROU asset or lease liability. The new leases standard requires a lessor to classify leases as either sales-type, direct financing or operating, similar to existing U.S. GAAP. Classification depends on the same five criteria used by lessees plus certain additional factors. The subsequent accounting treatment for all three lease types is substantially equivalent to existing U.S. GAAP for sales-type leases, direct financing leases, and operating leases. However, the new standard updates certain aspects of the lessor accounting model to align it with the new lessee accounting model, as well as with the new revenue standard under Topic 606. Lessees and lessors are required to provide certain qualitative and quantitative disclosures to enable users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The amendments are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on our consolidated results of operations or financial position. In March 2016, the FASB issued an Update (ASU 2016-09) to its guidance on “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting”. This amendment is intended to simplify the accounting for stock compensation. The areas for simplification in this Update involve several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. For public business entities, the amendments in this Update are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for any entity in any interim or annual period. The adoption of this guidance is not expected to have a material impact on our consolidated results of operations or financial position. In June 2016, the FASB issued an Update (ASU 2016-13) to its guidance on “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 requires credit losses on most financial assets measured at amortized cost and certain other instruments to be measured using an expected credit loss model (referred to as the current expected credit loss (CECL) model). Under this model, entities will estimate credit losses over the entire contractual term of the instrument (considering estimated prepayments, but not expected extensions or modifications unless reasonable expectation of a troubled debt restructuring exists) from the date of initial recognition of that instrument. The ASU also replaces the current accounting model for purchased credit impaired loans and debt securities. The allowance for credit losses for purchased financial assets with a more-than insignificant amount of credit deterioration since origination (“PCD assets”), should be determined in a similar manner to other financial assets measured on an amortized cost basis. However, upon initial recognition, the allowance for credit losses is added to the purchase price (“gross up approach”) to determine the initial amortized cost basis. The subsequent accounting for PCD financial assets is the same expected loss model described above. Further, the ASU made certain targeted amendments to the existing impairment model for available-for-sale (AFS) debt securities. For an AFS debt security for which there is neither the intent nor a more-likely-than-not requirement to sell, an entity will record credit losses as an allowance rather than a write-down of the amortized cost basis. For public business entities that are U.S. Securities and Exchange Commission (SEC) filers, the amendments in this Update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. All entities may adopt the amendments in this Update earlier as of the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. An entity will apply the amendments in this Update through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (that is, a modified-retrospective approach). The Company is currently evaluating the potential impact on our consolidated results of operations or financial position.

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 benefits certain key senior executives of the Bank who have been 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”). The SERP Plan is more fully described in Note 9 of the consolidated financial statements and notes thereto for the year ended June 30, 2016. The net periodic pension costs related to the SERP Plan for the three and six months ended December 31, 2016 were $81,000 and $158,000, respectively, and for the three and six months ended December 31, 2015 were $62,000 and $120,000, respectively, consisting primarily of service costs and interest costs. The total liability for the SERP Plan was $2.4 million and $2.0 million as of December 31, 2016 and June 30, 2016, respectively. The total liability for the SERP Plan includes both accumulated net periodic pension costs and participant contributions.

All share and per share data has been restated in all periods presented to reflect the 2-for-1 stock split, which was paid on March 15, 2016, as if the new share options had been granted at the same time as the original share options. Stock Option Plan At December 31, 2016 and 2015, all granted shares related to the 2008 Option Plan were fully vested, with no remaining compensation cost to be recognized. A summary of the Company’s stock option activity and related information for its option plan for the six months ended December 31, 2016 and 2015 is as follows: 2016 2015 Shares Weighted Average Exercise Price Per Share Shares Weighted Average Exercise Price Per Share Outstanding at beginning of year 64,770 $ 6.25 95,670 $ 6.25 Exercised (27,000 ) $ 6.25 (13,200 ) $ 6.25 Outstanding at period end 37,770 $ 6.25 82,470 $ 6.25 Exercisable at period end 37,770 $ 6.25 82,470 $ 6.25 The following table presents stock options outstanding and exercisable at September 30, 2016: Options Outstanding and Exercisable Range of Exercise Prices Number Outstanding Weighted Average Remaining Contractual Life Weighted Average Exercise Price $6.25 37,770 1.75 $6.25 The total intrinsic value of the options exercised during the three and six months ended December 31, 2016 was approximately $208,000 and $339,000, respectively. The total intrinsic value of the options exercised during the three and six months ended December 31, 2015 was approximately $82,000 and $115,000, respectively. There were no stock options granted during the six months ended December 31, 2016 or 2015. All outstanding options were fully vested at December 31, 2016 and 2015. 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”).

Basis of Presentation [Abstract]
Basis of Presentation	Within the accompanying unaudited consolidated statement of financial condition, and related notes to the consolidated financial statements, June 30, 2016 data was derived from the audited consolidated financial statements of Greene County Bancorp, Inc. (the “Company”) and its wholly owned subsidiaries, The Bank of Greene County (the “Bank”) and Greene Risk Management, Inc., and the Bank’s wholly owned subsidiaries, Greene County Commercial Bank and Greene Property Holdings, Ltd. The consolidated financial statements at and for the three and six months ended December 31, 2016 and 2015 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, 2016, 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 and six months ended December 31, 2016, are not necessarily indicative of results that may be expected for the entire fiscal year ending June 30, 2017. 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 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 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, 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 equity security for a period of time sufficient for a recovery in value; recent events specific to the issuer or industry; and for debt securities, the 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 write-downs to fair value 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. 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 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 through earnings.

Securities [Abstract]
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 three and six months ended December 31, 2016 or 2015.

Impact of Recent Accounting Pronouncements [Abstract]
Impact of Recent Accounting Pronouncements	In May 2014, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standard Update (“ASU) (ASU 2014-09) to amend its guidance on “Revenue from Contracts with Customers (Topic 606). The objective of the ASU is to align the recognition of revenue with the transfer of promised goods or services provided to customers in an amount that reflects the consideration which the entity expects to be entitled in exchange for those goods or services. This ASU will replace most existing revenue recognition guidance under GAAP when it becomes effective. In August, 2015, the FASB issued an amendment (ASU 2015-14) which defers the effective date of this new guidance by one year. More detailed implementation guidance on Topic 606 was issued in March 2016 (ASU 2016-08), April 2016 (ASU 2016-10) and May 2016 (ASU 2016-12), and the effective date and transition requirements for these ASUs are the same as the effective date and transition requirements of ASU 2014-09. The amendments in ASU 2014-09 are effective for public business entities for annual periods, beginning after December 15, 2017. The Company has not yet determined the effect of the standard on its ongoing financial reporting. In August 2014, the FASB issued an amendment (ASU 2014-14) to its guidance on “Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40)”. The objective of the ASU is to reduce the diversity in how creditors classify government-guaranteed mortgage loans, including FHA or VA guaranteed loans, upon foreclosure, to provide more decision-useful information about a creditor’s foreclosed mortgage loans that are expected to be recovered, at least in part, through government guarantees. 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, 2017. Public entities would be permitted to elect to early adopt for annual reporting periods beginning after December 15, 2016. The adoption of this guidance is not expected to have a material impact on our consolidated results of operations or financial position. In January 2015, the FASB issued an Update (ASU 2015-01) to its guidance on “Income Statement-Extraordinary and Unusual Items (Subtopic 225-20)”. The objective of the ASU is to simplify the income statement presentation by eliminating the concept of extraordinary items, and will align GAAP more closely with International Accounting Standards which prohibits the presentation and disclosure of extraordinary items. The amendments in this Update were effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. The adoption of this guidance did not have a material impact on our consolidated results of operations or financial position. In January 2016, the FASB issued an Update (ASU 2016-01) to its guidance on “Financial Instruments (Subtopic 825-10)”. This amendment addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. These amendments require equity securities to be measured at fair value with changes in the fair value to be recognized through net income. The amendments also simplify the impairment assessment of equity investments without readily determinable fair values by requiring assessment for impairment qualitatively at each reporting period. For public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption of the amendments in this Update is not permitted. The adoption of this guidance is not expected to have a material impact on our consolidated results of operations or financial position. In February 2016, the FASB issued an Update (ASU 2016-02) to its guidance on “Leases (Topic 842)”. The new leases standard applies a right-of-use (ROU) model that requires a lessee to record, for all leases with a lease term of more than 12 months, an asset representing its right to use the underlying asset and a liability to make lease payments. For leases with a term of 12 months or less, a practical expedient is available whereby a lessee may elect, by class of underlying asset, not to recognize an ROU asset or lease liability. The new leases standard requires a lessor to classify leases as either sales-type, direct financing or operating, similar to existing U.S. GAAP. Classification depends on the same five criteria used by lessees plus certain additional factors. The subsequent accounting treatment for all three lease types is substantially equivalent to existing U.S. GAAP for sales-type leases, direct financing leases, and operating leases. However, the new standard updates certain aspects of the lessor accounting model to align it with the new lessee accounting model, as well as with the new revenue standard under Topic 606. Lessees and lessors are required to provide certain qualitative and quantitative disclosures to enable users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The amendments are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on our consolidated results of operations or financial position. In March 2016, the FASB issued an Update (ASU 2016-09) to its guidance on “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting”. This amendment is intended to simplify the accounting for stock compensation. The areas for simplification in this Update involve several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. For public business entities, the amendments in this Update are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for any entity in any interim or annual period. The adoption of this guidance is not expected to have a material impact on our consolidated results of operations or financial position. In June 2016, the FASB issued an Update (ASU 2016-13) to its guidance on “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 requires credit losses on most financial assets measured at amortized cost and certain other instruments to be measured using an expected credit loss model (referred to as the current expected credit loss (CECL) model). Under this model, entities will estimate credit losses over the entire contractual term of the instrument (considering estimated prepayments, but not expected extensions or modifications unless reasonable expectation of a troubled debt restructuring exists) from the date of initial recognition of that instrument. The ASU also replaces the current accounting model for purchased credit impaired loans and debt securities. The allowance for credit losses for purchased financial assets with a more-than insignificant amount of credit deterioration since origination (“PCD assets”), should be determined in a similar manner to other financial assets measured on an amortized cost basis. However, upon initial recognition, the allowance for credit losses is added to the purchase price (“gross up approach”) to determine the initial amortized cost basis. The subsequent accounting for PCD financial assets is the same expected loss model described above. Further, the ASU made certain targeted amendments to the existing impairment model for available-for-sale (AFS) debt securities. For an AFS debt security for which there is neither the intent nor a more-likely-than-not requirement to sell, an entity will record credit losses as an allowance rather than a write-down of the amortized cost basis. For public business entities that are U.S. Securities and Exchange Commission (SEC) filers, the amendments in this Update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. All entities may adopt the amendments in this Update earlier as of the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. An entity will apply the amendments in this Update through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (that is, a modified-retrospective approach). The Company is currently evaluating the potential impact on our consolidated results of operations or financial position.

[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 are adjusted downwards by management for qualitative factors such as the estimated costs to liquidate the collateral.
