Nature Of Operations And Basis Of Presentation [Abstract]
NATURE OF OPERATIONS AND BASIS OF PRESENTATION	1. NATURE OF OPERATIONS AND BASIS OF PRESENTATION Prudential Bancorp, Inc. (the “Company”) is a Pennsylvania corporation that was incorporated in June 2013 to be the successor corporation of Prudential Bancorp, Inc. of Pennsylvania (“Old Prudential Bancorp”), the former stock holding company for Prudential Savings Bank (the “Bank”), a Pennsylvania-chartered, FDIC-insured savings bank with seven full service branches in the Philadelphia area. As of September 30, 2013, the Company was in organization and had not commenced operations; accordingly, the financial statements included as of and for the year ended September 30, 2013 are of Prudential Bancorp, Inc. of Pennsylvania. The Bank‘s primary federal banking regulator is the Federal Deposit Insurance Corporation. The Bank is principally in the business of attracting deposits from its community through its branch offices and investing those deposits, together with funds from borrowings and operations, primarily in single-family residential loans. The Bank’s sole subsidiary as of September 30, 2015 was PSB Delaware, Inc. (“PSB”), a Delaware-chartered corporation established to hold certain investments. As of September 30, 2016, PSB had assets of $119.4 million primarily consisting of investment and mortgage-backed securities. The Company’s primary market area is Philadelphia, in particular South Philadelphia and Center City, as well as Delaware County. The Company also conducts business in Bucks, Chester and Montgomery Counties which, along with Delaware County, comprise the suburbs of Philadelphia. We also make loans in contiguous counties in southern New Jersey. The second step conversion of the MHC was completed on October 9, 2013. In connection with the conversion, the Company issued an aggregate of 9,544,809 shares of common stock through a public offering and the exchange of Old Prudential Bancorp’s common stock owned by the public other than the MHC which was exchanged for 0.9442 shares of the Company’s common stock for each share of Old Prudential Bancorp. Share amounts and per share data in the consolidated financial statements and notes to consolidated financial statements have been adjusted to reflect the exchange.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Consolidation – . Use of Estimates in the Preparation of Financial Statements — Cash and Cash Equivalents — Investment Securities and Mortgage-Backed Securities — Held to Maturity Available for Sale Other-than-temporary impairment Loans Receivable — Loan Origination and Commitment Fees — Interest on Loans — Allowance for Loan Losses — The allowance for loan losses represents the amount which management estimates is adequate to provide for probable losses inherent in its loan portfolio as of the Consolidated Statement of Financial Condition date. The allowance method is used in providing for loan losses. Accordingly, all loan losses are charged to the allowance, and all recoveries are credited to it. The allowance for loan losses is established through a provision for loan losses charged to operations. The provision for loan losses is based on management’s periodic evaluation of individual loans, economic factors, past loan loss experience, changes in the composition and volume of the portfolio, and other relevant factors, both qualitative and quantitative. The estimates used in determining the adequacy of the allowance for loan losses, including the amounts and timing of future cash flows expected on impaired loans, are particularly susceptible to changes in the near term. Impaired loans are loans for which it is not probable to collect all amounts due according to the contractual terms of the loan agreements. Management individually evaluates such loans for impairment and does not aggregate loans by major risk classifications. Factors considered by management in determining impairment include payment status and collateral value. The amount of impairment for impaired loans is determined by the difference between the present value of the expected cash flows related to the loans, using the original interest rate, and their recorded value, or as a practical expedient in the case of collateralized loans, the difference between the fair value of the collateral and the recorded amount of the loans. When foreclosure is probable, impairment is measured based on the fair value of the collateral. Mortgage loans and consumer loans are comprised of large groups of smaller balance homogeneous loans which are evaluated for impairment collectively. Loans that experience insignificant payment delays, which are defined as less than 90 days, generally are not classified as impaired. Management determines the significance of payment delays on a case-by-case basis taking into consideration all of the circumstances surrounding the loan and the borrower including the length of the delay, the borrower’s prior payment record, and the amount of shortfall in relation to the principal and interest owed. Real Estate Owned — Federal Home Loan Bank of Pittsburgh (“FHLB”) Stock – The Company is a member of the Federal Home Loan Bank of Pittsburgh and as such, is required to maintain a minimum investment in stock of the Federal Home Loan Bank that varies with the level of advances outstanding with the Federal Home Loan Bank. The stock is bought from and sold to the Federal Home Loan Bank based upon its $100 par value. The stock does not have a readily determinable fair value and as such is classified as restricted stock, carried at cost and evaluated for impairment by management. The stock’s value is determined by the ultimate recoverability of the par value rather than by recognizing temporary declines. The determination of whether the par value will ultimately be recovered is influenced by criteria such as the following: (a) the significance of the decline in net assets of the Federal Home Loan Bank as compared to the capital stock amount and the length of time this situation has persisted; (b) commitments by the Federal Home Loan Bank to make payments required by law or regulation and the level of such payments in relation to the operating performance; (c) the impact of legislative and regulatory changes on the customer base of the Federal Home Loan Bank; and (d) the liquidity position of the Federal Home Loan Bank. The Federal Home Loan Bank continues to report net income, continues to declare quarter cash dividends and had its Aaa bond rating affirmed by Moody’s and AA+ rating affirmed by Standard and Poor’s during 2015 and remain unchanged as of September 30, 2016.With consideration given to these factors, management concluded that the stock was not impaired at September 30, 2016 or 2015. Office Properties and Equipment — Cash Surrender Value of Life Insurance— Dividend Payable Employee Stock Ownership Plan – Share-Based Compensation Treasury Stock – Comprehensive Income Income Taxes— In evaluating the Company’s ability to recover deferred tax assets, management considers all available positive and negative evidence, including past operating results and forecast of future taxable income. In determining future taxable income, management makes assumptions for the amount of taxable income, the reversal of temporary differences and the implementation of feasible and prudent tax planning strategies. These assumptions require management to make judgments about future taxable income and are consistent with the plans and estimates the Company uses to manage the business. Any reduction in estimated future taxable income may require management to record an additional valuation allowance against the deferred tax assets. An increase in the valuation allowance would result in additional income tax expense in the period and could have a significant impact on our future earnings. Transfers and Servicing of Financial Assets and Extinguishments of Liabilities — Interest Rate Swap Agreement The gain or loss on a derivative designated and qualifying as a fair value hedging instrument, as well as the offsetting gain or loss on the hedged item attributable to the risk being hedged, is recognized currently in earnings in the same accounting period. The effective portion of the gain or loss on a derivative designated and qualifying as a cash flow hedging instrument is initially reported as a component of other comprehensive income and subsequently reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The ineffective portion of the gain or loss on the derivative instrument, if any, is recognized currently in earnings. For cash flow hedges, the net settlement (upon close-out or termination) that offsets changes in the value of the hedged debt is deferred and amortized into net interest income over the life of the hedged debt. For fair value hedges, the net settlement (upon close-out or termination) that offsets changes in the value of the loans adjusts the basis of the loans and is deferred and amortized to loan interest income over the life of the loans. The portion, if any, of the net settlement amount that did not offset changes in the value of the hedged asset or liability is recognized immediately in noninterest income. Interest rate derivative financial instruments receive hedge accounting treatment only if they are designated as a hedge and are expected to be, and are, effective in substantially reducing interest rate risk arising from the assets and liabilities identified as exposing the Company to risk. Those derivative financial instruments that do not meet specified hedging criteria would be recorded at fair value, with changes in fair value recorded in income. If periodic assessment indicates derivatives no longer provide an effective hedge, the derivative contracts would be closed out and settled, or classified as a trading activity.

EARNINGS PER SHARE	3. EARNINGS PER SHARE Basic earnings per share is computed based on the weighted average number of common shares outstanding. Diluted earnings per share is computed based on the weighted average number of common shares outstanding and common share equivalents (“CSEs”) that would arise from the exercise of dilutive securities. The calculated basic and diluted earnings per share are as follows: Year Ended September 30, 2016 2015 2014 (Dollars in Thousands Except Per Share Data) Basic Diluted Basic Diluted Basic Diluted Net income $ 2,720 $ 2,720 $ 2,232 $ 2,232 $ 1,780 $ 1,780 Weighted average shares outstanding 7,417,044 7,417,044 8,335,273 8,335,273 9,061,193 9,061,193 Effect of CSEs - 217,701 - 114,817 - 216,885 Adjusted weighted average shares used in earnings per share computation 7,417,044 7,634,745 8,335,273 8,450,090 9,061,193 9,278,078 Earnings per share - basic and diluted $ 0.37 $ 0.36 $ 0.27 $ 0.26 $ 0.20 $ 0.19 As of September 30, 2016 and 2015, there were 554,445 and 442,756 shares of common stock, respectively, subject to options with an exercise price less than the then current market and which were included in the computation of diluted earnings per share. All options shares vested as of September 30, 2016 and 2015 have exercise prices considered in the money and are consider dilutive. The weighted exercise price for the stock options representing the 383,016 anti-dilutive shares was $11.83 at September 30, 2014.

The Bank is not required to maintain any specific collateral for its borrowings; therefore these securities are not restricted and could be sold or transferred if needed. The following table shows the gross unrealized losses and related fair values of the Company’s investment securities, aggregated by investment category and the length of time that individual securities had been in a continuous loss position at September 30, 2016: Less than 12 months More than 12 months Total Gross Gross Gross Unrealized Fair Unrealized Fair Unrealized Fair Losses Value Losses Value Losses Value (Dollars in Thousands) Securities Available for Sale: Mortgage-backed securities -U.S. government agencies $ (50 ) $ 16,498 $ 52 $ 6,718 $ (102 ) $ 23,216 Corporate debt securities (19 ) 3,955 - - (19 ) 3,955 Total securities available for sale $ (69 ) $ 20,453 $ 52 $ 6,718 $ (121 ) $ 27,171 Securities Held to Maturity: U.S. government and agency obligations $ (129 ) $ 20,371 $ - $ - $ (129 ) $ 20,371 Total securities held to maturity $ (129 ) $ 20,371 $ - $ - $ (129 ) $ 20,371 Total $ (198 ) $ 40,824 $ 52 $ 6,718 $ (250 ) $ 47,542 Management evaluates securities for other-than-temporary impairment (“OTTI”) at least once per quarter, and more frequently when economic or market conditions warrant such evaluation. The evaluation is based upon factors such as the creditworthiness of the issuers/guarantors, the underlying collateral, if applicable, and the continuing performance of the securities. Management also evaluates other facts and circumstances that may be indicative of an OTTI condition. This includes, but is not limited to, an evaluation of the type of security, the length of time and extent to which the fair value of the security has been less than cost, and the near-term prospects of the issuer. Management has reviewed its investment securities portfolios and determined that during the year ended September 30, 2016, there were no impairment required for its investment portfolio deemed other than temporarily impaired. The Company assesses whether the credit loss existed by considering whether (1) the Company has the intent to sell the security, (2) it is more likely than not that it will be required to sell the security before recovery, or (3) it does not expect to recover the entire amortized cost basis of the security. The Company bifurcates the OTTI impact on impaired securities where impairment in value was deemed to be other than temporary between the component representing credit loss and the component representing loss related to other factors. The portion of the fair value decline attributable to credit loss must be recognized through a charge to earnings. The credit component is determined by comparing the present value of the cash flows expected to be collected, discounted at the rate in effect before recognizing any OTTI with the amortized cost basis of the debt security. The Company uses the cash flow expected to be realized from the security, which includes assumptions about interest rates, timing and severity of defaults, estimates of potential recoveries, the cash flow distribution from the bond indenture and other factors, then applies a discount rate equal to the effective yield of the security. The difference between the present value of the expected cash flows and the amortized book value is considered a credit loss. The fair market value of the security is determined using the same expected cash flows; the discount rate is a rate the Company determines from the open market and other sources as appropriate for the security. The difference between the fair market value and the security’s remaining amortized cost is recognized in other comprehensive income. For both years ended September 30, 2016 and 2015, the Company determined that no OTTI had occurred within the investment and mortgage-back securities portfolios. The following is a rollforward for the year ended September 30, 2014 of the amounts recognized in earnings related to credit losses on securities which the Company had recorded OTTI charges through earnings and other comprehensive income.

During the fiscal year ended September 30, 2015, the Company did not record any gains or losses nor did it sell any securities from it’s AFS portfolio. During the fiscal year ended September 30, 2016, the Company sold for $2.9 million mortgage-backed securities classified as held-to-maturity for total proceeds of $3.1 million, that had a remaining balance of less than 15% of its original par value. These sales did not taint the Company’s intent to hold the remaining portfolio.

The ultimate repayment of these loans at September 30, 2016 and 2015 is dependent, to a certain degree, on the local economy and real estate market.

Management evaluates all loans classified as substandard or lower and loans delinquent 90 plus days for potential impairment. Loans are considered to be impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Once the determination is made that a loan is impaired, the determination of whether a specific allocation of the allowance is necessary is generally measured by comparing the recorded investment in the loan to the fair value of the loan using one of the following three methods: (a) the present value of the expected future cash flows discounted at the loan’s effective interest rate; (b) the loan’s observable market price; or (c) the fair value of the collateral less selling costs. Management primarily utilizes the fair value of collateral method as a practically expedient alternative. The following table presents impaired loans by class, segregated by those for which a specific allowance was required and those for which a specific allowance was not necessary as of September 30, 2016: Impaired Loans with Impaired Loans with No Specific Specific Allowance Allowance Total Impaired Loans (Dollars in Thousands) Unpaid Recorded Related Recorded Recorded Principal Investment Allowance Investment Investment Balance One-to-four family residential $ - $ - $ 5,553 $ 5,553 $ 5,869 Multi-family - - 335 335 335 Commercial real estate - - 3,154 3,154 3,154 Construction and land development - - 10,288 10,288 10,288 Commercial business - - 99 99 99 Total Loans $ - $ - $ 19,429 $ 19,429 $ 19,745 The following table presents impaired loans by class, segregated by those for which a specific allowance was required and those for which a specific allowance was not necessary as of September 30, 2015: Impaired Loans with Impaired Loans with No Specific Specific Allowance Allowance Total Impaired Loans (Dollars in Thousands) Unpaid Recorded Related Recorded Recorded Principal Investment Allowance Investment Investment Balance One-to-four family residential $ - $ - $ 4,206 $ 4,206 $ 4,550 Commercial real estate - - 3,768 3,768 3,768 Construction and land development - - 8,796 8,796 8,796 Total Loans $ - $ - $ 16,770 $ 16,770 $ 17,114 The following tables present the average investment in impaired loans and related interest income recognized for the periods indicated: September 30, 2016 Average Income Recognized Income (Dollars in Thousands) One-to four-family residential $ 5,099 $ 129 $ 101 Multi-family residential 344 24 - Commercial real estate 3,565 96 12 Construction and land development 9,604 - 62 Commercial business 8 - - Total $ 18,620 $ 249 $ 175 September 30, 2015 Average Income Income (Dollars in Thousands) One-to four-family residential $ 8,734 $ 431 $ 147 Multi-family residential 289 19 - Commercial real estate 3,840 210 71 Construction and land development 8,413 437 194 Total $ 21,276 $ 1,097 $ 412 September 30, 2014 Average Income Recognized Income (Dollars in Thousands) One-to four-family residential $ 10,802 $ 305 $ 53 Multi-family residential 376 26 - Commercial real estate 2,585 70 19 Construction and land development 3,582 247 - Total $ 17,345 $ 648 $ 72 Federal banking regulations and our policies require that the Bank utilize an internal asset classification system as a means of reporting problem and potential problem assets. The Bank has incorporated an internal asset classification system, consistent with Federal banking regulations, as a part of the credit monitoring system. Management currently classifies problem and potential problem assets as “special mention,” “substandard,” “doubtful” or “loss” assets. An asset is considered “substandard” if it is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. “Substandard” assets include those characterized by the “distinct possibility” that the insured institution will sustain “some loss” if the deficiencies are not corrected. Assets classified as “doubtful” have all of the weaknesses inherent in those classified “substandard” with the added characteristic that the weaknesses present make “collection or liquidation in full,” on the basis of currently existing facts, conditions, and values, “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 specific loss reserve is not warranted. Assets which do not currently expose the insured institution to sufficient risk to warrant classification in one of the aforementioned categories but possess weaknesses are required to be designated “special mention.” The following tables present the classes of the loan portfolio in which a formal risk weighting system is utilized summarized by the aggregate “Pass” and the criticized category of “special mention”, and the classified categories of “substandard” and “doubtful” within the Bank’s risk rating system. The Bank had no loans classified as “loss” at the dates presented.

The allowance for loan losses is established through a provision for loan losses charged to expense. Management maintains the allowance at a level believed to cover all known and inherent losses in the portfolio that are both probable and reasonable to estimate at each reporting date. Management reviews the allowance for loan losses no less than quarterly in order to identify those inherent losses and to assess the overall collection probability for the loan portfolio in view of these inherent losses. For each primary type of loan, a loss factor is established reflecting an estimate of the known and inherent losses in such loan type using both a quantitative analysis as well as consideration of qualitative factors. The evaluation process includes, among other things, an analysis of delinquency trends, non-performing loan trends, the level of charge-offs and recoveries, prior loss experience, total loans outstanding, the volume of loan originations, the type, size and geographic concentration of our loans, the value of collateral securing the loans, the borrower’s ability to repay and repayment performance, the number of loans requiring heightened management oversight, local economic conditions and industry experience. Commercial real estate loans entail significant additional credit risks compared to one-to four-family residential mortgage loans, as they generally involve large loan balances concentrated with single borrowers or groups of related borrowers. In addition, the payment experience on loans secured by income-producing properties typically depends on the successful operation of the related real estate project and/or business operation of the borrower who is also the primary occupant, and thus may be subject to a greater extent to the effects of adverse conditions in the real estate market and in the economy in general. Commercial business loans typically involve a higher risk of default than residential loans of like duration since their repayment is generally dependent on the successful operation of the borrower’s business and the sufficiency of collateral, if any. Land acquisition, development and construction lending exposes us to greater credit risk than permanent mortgage financing. The repayment of land acquisition, development and construction loans depends upon the sale of the property to third parties or the availability of permanent financing upon completion of all improvements. These events may adversely affect the borrower and the value of the collateral property. The following tables summarize the primary segments of the allowance for loan losses, segmented into the amount required for loans individually evaluated for impairment and the amount required for loans collectively evaluated for impairment as of September 30, 2016 and 2015.

The Company determined it was prudent to record a provision for fiscal year 2016 primarily due to the increased level of commercial real estate loans offset by a reduction in single-family residential loans. The provision for loan losses was deemed necessary for fiscal 2015 due to the increase in the level of commercial real estate and construction loans outstanding, charge-offs incurred during fiscal 2015 and the classification of a $10.3 million loan workout relationship as non-performing. The Company believes that the allowance for loan losses at September 30, 2016 is sufficient to cover all inherent and known losses associated with the loan portfolio at such date. At September 30, 2016, the Company’s non-performing assets totaled $16.5 million or 2.9% of total assets as compared to $14.8 million or 3.0% of total assets at September 30, 2015. All of the increase was due to the placement on non-accrual of the entire amount of the Company’s largest loan relationship totaling $12.3 million and consisting of nine loans. Non-performing assets at September 30, 2016 included five construction loans aggregating $10.3 million, 17 one-to-four-family residential loans aggregating $2.9 million, one single-family residential investment property loan totaling $1.4 million and two commercial real estate loans aggregating $1.3 million. Non-performing assets also included at September 30, 2016 two real estate properties consisting of one single-family residential property totaling $375,000 and a commercial real estate property totaling $206,000. At September 30, 2016, the Company had ten loans aggregating $8.2 million that were classified as troubled debt restructurings (“TDRs”). Three of such loans aggregating $5.7 million as of September 30, 2016 were classified as non-performing as a result of not achieving a sufficiently long payment history, under the restructured terms, to justify returning the loans to performing (accrual) status. Two of these three loans totaling $4.3 million (which are part of the Company’s largest relationship referenced above) are over 90 days past due resulting from the discontinuation of funding by the Company of the development project (discussed below) due to the re-negotiation of the project’s future direction to completion. The third loan, consisting of a residential loan of approximately $1.4 million, has made all of its required payments to date, but the Company has not returned the loan to performing status due to concerns with regard to the borrower’s ability to make remaining payments due. The remaining eight TDRs have performed in accordance with the terms of their revised agreements. As of September 30, 2016, the Company had reviewed $19.4 million of loans for possible impairment of which $14.6 million was deemed classified as substandard compared to $16.8 million reviewed for possible impairment and $12.4 million of which was classified substandard as of September 30, 2015. Management will continue to monitor and modify the allowance for loan losses as conditions dictate. No assurances can be given that the level of allowance for loan losses will cover all of the inherent losses on the loans or that future adjustments to the allowance for loan losses will not be necessary if economic and other conditions differ substantially from the economic and other conditions used by management to determine the current level of the allowance for loan losses. The following tables set forth a summary of the TDRs activity for the years ended September 30, 2016, 2015 and 2014. All of the TDRs involved changes in the interest rates on the loans; no debt was forgiven. At September 30, 2016, out of the 11 TDRs loans, eight were performing and the remaining three were classified as non-performing, of which one loan was performing in accordance with their modified terms: As of and for the Year Ended September 30, 2016 Restructured Current Period (amount in thousands) Number of Pre- Modification Post-Modification One-to-four family residential 1 $ 482 $ 482 1 $ 482 $ 482 As of and for the Year Ended September 30, 2015 Restructured Current Period (amount in thousands) Number of Pre- Modification Post-Modification Commerical real estate 1 $ 750 $ 750 Construction and land development 1 3,665 3,665 2 $ 4,415 $ 4,415 As of and for the Year Ended September 30, 2014 Restructured Current Period (amount in thousands) Number of Pre- Modification Post-Modification One-to four- family 1 $ 1,455 $ 1,455 Commerical real estate 1 877 877 2 $ 2,332 $ 2,332 As of September 30, 2016, consist of two loans deemed to be TDRs aggregating $4.3 million, consisting of one construction and development loan in the amount of $3.6 million and a commercial real estate loan in the amount of $730,000, both of which were in default under their modified terms. Both loans are related to the Company’s largest borrower. At September 30, 2016, the Company had nine consumer mortgage with a carrying amount of $1.1 million that is secured by residential real estate property for which foreclosure is proceedings are in process according to local jurisdictions.

INCOME TAXES	11. INCOME TAXES The Company files a consolidated federal income tax return. The Company uses the specific charge-off method for computing reserves for bad debts. Generally this method allows the Company to deduct an annual addition to the reserve for bad debt equal to its net charge-offs. The provision for income taxes for the years ended September 30, consists of the following: Year Ended September 30, 2016 2015 2014 (Dollars in Thousands) Current: Federal expense $ 1,275 $ 461 $ 690 Total current taxes 1,275 461 690 Deferred income tax benefit (16 ) (345 ) - Total income tax provision $ 1,259 $ 116 $ 690 Items that gave rise to significant portions of deferred income taxes are as follows: September 30, 2016 2015 (Dollars in Thousands) Deferred tax assets: Allowance for loan losses $ 1,289 $ 1,185 Non-accrual interest 163 86 Accrued vacation 13 119 Capital loss carryforward 378 534 Post-retirement benefit plans 96 126 Split dollar life insurance 18 19 Unrealized losses on interest rate swaps 69 - Employee benefit plans 434 530 Total deferred tax assets 2,460 2,599 Valuation allowance (378 ) (534 ) Total deferred tax assets, net of valuation allowance 2,082 2,065 Deferred tax liabilities: Property 423 365 Unrealized gains on available for sale securities 500 10 481(a)Adjustment 12 - Deferred loan fees 578 715 Total deferred tax liabilities 1,513 1,090 Net deferred tax asset $ 569 $ 975 The Company establishes a valuation allowance for deferred tax assets when management believes that the deferred tax assets are not likely to be realized either through a carry back to taxable income in prior years, future reversals of existing taxable temporary differences, and, to a lesser extent, future taxable income. The valuation allowance totaled $378,000 and $534,000 at September 30, 2016 and 2015, respectively. The gross deferred tax assets related to impairment losses and capital loss carryforwards decreased in the aggregate by $156 thousand during the year ended September 30, 2016, primarily due to the sale of AFS investment securities.

Banking and Thrift [Abstract]
REGULATORY CAPITAL REQUIREMENTS	12. REGULATORY CAPITAL REQUIREMENTS The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory – and possibly additional discretionary – actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The Company’s and the Bank’s capital amounts and the Bank’s classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the table below) of Tier 1 capital (as defined in the regulations) to average assets (as defined) and risk-weighted assets (as defined), and of total capital (as defined) to risk-weighted assets. Management believes, as of September 30, 2016 and 2015, that the Company and the Bank met all regulatory capital adequacy requirements to which they each are subject. To be categorized as well capitalized, the Bank must maintain the minimum Tier 1 capital, Tier common equity, Tier 1 risk-based and total risk-based ratios as set forth in the table below. The Company’s and the Bank’s actual capital amounts and ratios are also presented in the following table: To Be Well Capitalized Under Prompt Required for Capital Corrective Action Actual Adequacy Purposes Provisions Amount Ratio Amount Ratio Amount Ratio (Dollars in Thousands) September 30, 2016: Tier 1 capital (to average assets) Company $ 113,205 20.41 % N/A N/A N/A N/A Bank 100,552 18.15 $ 22,157 4.0 $ 27,697 5.0 % Tier 1 Common (to risk-weighted assets) Company 113,205 38.57 N/A N/A N/A N/A Bank 100,552 34.36 13,171 4.5 19,024 6.5 Tier 1 capital (to risk-weighted assets) Company 113,205 38.57 N/A N/A N/A N/A Bank 100,552 34.36 17,559 6.0 23,415 8.0 Total capital (to risk-weighted assets) Company 116,512 39.70 N/A N/A N/A N/A Bank 103,859 35.49 23,415 8.0 29,268 10.0 September 30, 2015: Tier 1 capital (to average assets) Company $ 116,903 23.73 % N/A N/A N/A N/A Bank 96,034 19.50 $ 19,699 4.0 $ 24,624 5.0 % Tier 1 Common (to risk-weighted assets) Company 116,921 50.63 N/A N/A N/A N/A Bank 96,052 41.66 10,376 4.5 14,987 6.5 Tier 1 capital (to risk-weighted assets) Company 116,903 50.63 N/A N/A N/A N/A Bank 96,034 41.65 13,834 6.0 18,446 8.0 Total capital (to risk-weighted assets) Company 120,016 51.98 N/A N/A N/A N/A Bank 99,147 43.00 18,446 8.0 23,057 10.0

EMPLOYEE BENEFITS	13. EMPLOYEE BENEFITS The Bank is a member of a multi-employer (under the provisions of the Employee Retirement Income Security Act of 1974 and the Internal Revenue Code of 1986) defined benefit pension plan covering all employees meeting certain eligibility requirements. The Bank’s policy is to fund pension costs accrued. The expense relating to this plan for the years ended September 30, 2016, 2015 and 2014 was $256,000, $623,000 and $663,000, respectively. There are no collective bargaining agreements in place that require contributions to the plan. Additional information regarding the plan as of September 30, 2016 is noted below: Legal Name of Plan Pentegra Defined Benefit Plan for Plan Employer Identification Number 13-5645888 The Company's Contribution for the year ended September 30, 2016 $222,000 Are Company's Contributions more than 5% of total contributions? No Funded Status 95.85% The Pentegra Defined Benefits Plan for Financial Institutions is a single plan under Internal Revenue Code Section 413 (c) and, as a result, all of the assets stand behind all of the liabilities. Accordingly, under the plan, contributions made by a participating employer may be used to provide benefits to participants of other participating employers. During November 2015, the Plan was frozen in an effort to reduce expenses on a going forward basis. The Bank also has a defined contribution plan for employees meeting certain eligibility requirements. The defined contribution plan may be terminated at any time at the discretion of the Bank. There was no expense relating to this plan for the years ended September 30, 2016, 2015 and 2014. The Company eliminated the employer match in conjunction with the establishment of the employee stock ownership plan (“ESOP”) discussed below. The Bank maintains an ESOP for substantially all of its full-time employees meeting certain eligibility requirements. The purchase of shares of the Company's common stock by the ESOP was funded by loans from the Company. The loans will be repaid principally from the Bank's contributions to the ESOP. Shares of the Company's common stock purchased by the ESOP are held in a suspense account and released for allocation to participants on a pro rata basis as debt service payments are made on the loans. Shares released are allocated to each eligible participant based on the ratio of each such participant's compensation, as defined in the ESOP, to the total compensation of all eligible plan participants. As the unearned shares are released and allocated among participants, the Bank recognizes compensation expense based on the current market price of the shares released. The ESOP purchased 712,721 shares of the Company’s common stock for an aggregate cost of approximately $7.6 million in fiscal 2015 and fiscal 2014. As of September 30, 2016, the Company had allocated a total of 243,734 shares from the suspense account to participants and committed to release an additional 35,517 shares. The expense relating to the ESOP for the years ended September 30, 2016, 2015 and 2014 was $526,000, $467,000 and $389,000, respectively. The Company maintains the 2008 Recognition and Retention Plan (“RRP”) which is administered by a committee of the Board of Directors of the Company. The RRP provides for the grant of shares of common stock of the Company to officers, employees and directors of the Company. In order to fund the grant of shares under the RRP, the RRP Trust purchased 213,528 shares (on a converted basis) of the Company’s common stock in the open market for approximately $2.5 million, at an average purchase price per share of $11.49 as part of the RRP. The Company made sufficient contributions to the RRP Trust to fund these purchases. As of September 30, 2015, During Fiscal year 2016 7,473 shares have been forfeited under RRP and were granted in August 2016, all the shares had been awarded as part of the RRP. Shares subject to awards under the RRP generally vest at the rate of 20% per year over five years. As of September 30, 2016, 195,083 of the awarded shares of the Plan had become fully vested. During February 2015, shareholders approved the 2014 Stock Incentive Plan (the “2014 SIP”). As part of the 2014 SIP, a maximum of 285,655 shares can be awarded as restricted stock awards or units, of which 235,500 shares were awarded during February 2015 of which 41,800 have vested and 45,000 shares have been forfeited. In August 2016, the Company granted 3,027 shares under 2014 SIP. During the year ended September 30, 2016, approximately $463,000 was recognized in compensation expense for the RRP. Tax benefits of $219,000 were recognized during the year ended September 30, 2016.Tax benefits of $131,000 were recognized during the year ended September 30, 2015. During the year ended September 30, 2015, approximately $387,000 was recognized in compensation expense for the RRP. At September 30, 2016, approximately $2.9 million of additional compensation expense for the shares awarded related to the RRP remained unrecognized. A summary of the Company’s non-vested stock award activity for the year ended September 30, 2016 and 2015 is presented in the following table: Year Ended Number of Weighted Average Nonvested stock awards at beginning of year 241,428 $ 11.74 Issued 10,500 14.42 Forfeited (30,180 ) 11.92 Vested (48,960 ) 11.60 Nonvested stock awards at the end of the period 172,788 $ 12.03 Year Ended Number of Weighted Average Nonvested stock awards at beginning of year 38,055 $ 8.07 Issued 235,500 12.23 Forfeited (21,813 ) 11.85 Vested (10,314 ) 9.07 Nonvested stock awards at the end of the period 241,428 $ 11.74 The Company maintains the Stock Option Plan (the “Option Plan”) which authorizes the grant of stock options to officers, employees and directors of the Company to acquire shares of common stock with an exercise price at least equal to the fair market value of the common stock on the grant date.

COMMITMENTS AND CONTINGENT LIABILITIES At September 30, 2016, the Company had $9.9 million in outstanding commitments to originate fixed and variable-rate loans with market interest rates ranging from 3.75% to 5.25%. At September 30, 2015, the Company had $2.7 million in outstanding commitments to originate fixed and variable-rate loans with market interest rates ranging from 4.25% to 5.25%. The aggregate undisbursed portion of loans-in-process amounted to $5.4 million and $17.1 million, respectively, at September 30, 2016 and 2015. The Company also had commitments under unused lines of credit of $3.3 million and $6.1 million, respectively, and letters of credit outstanding of $1.9 million and $2.6 million, respectively, at September 30, 2016 and 2015. The Company is subject to various pending claims and contingent liabilities arising in the normal course of business which are not reflected in the accompanying consolidated financial statements. Management considers that the aggregate liability, if any, resulting from such matters will not be material. Among the Company’s contingent liabilities are exposures to limited recourse arrangements with respect to the Company’s sales of whole loans and participation interests. At September 30, 2016, the exposure, which represents a portion of credit risk associated with the sold interests, amounted to $32,000. This exposure is for the life of the related loans and payables, on the Company’s proportionate share, as actual losses are incurred. The Company is involved in various legal proceedings occurring in the ordinary course of business. Management of the Company, based on discussions with litigation counsel, does not believe that such proceedings will have a material adverse effect on the financial condition or operations of the Company. There can be no assurance that any of the outstanding legal proceedings to which the Company is party will not be decided adversely to the Company's interest and have a material adverse effect on the financial condition and operations of the Company.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT	16. FAIR VALUE MEASUREMENT The fair value estimates presented herein are based on pertinent information available to management as of September 30, 2016 and 2015, respectively. Although management is not aware of any factors that would significantly affect the fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since that date and, therefore, current estimates of fair value may differ significantly from the amounts presented herein. Generally accepted accounting principles used in the United States establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value. The three broad levels of hierarchy are as follows: Level 1 Quoted prices in active markets for identical assets or liabilities. Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. Those assets as of September 30, 2016 which are to be measured at fair value on a recurring basis are as follows: Level 1 Level 2 Level 3 Total (Dollars in Thousands) Assets: Securities available for sale: U.S. Government and agency obligations $ - $ 21,024 $ - $ 21,024 Mortgage-backed securities - U.S. Government agencies - 91,575 - 91,575 Corporate bonds - 26,053 - 26,053 FHLMC preferred stock 42 - - 42 Total $ 42 $ 138,652 $ - $ 138,694 Liabilities Interest rate swap contracts $ - $ 202 $ - $ 202 Total $ - $ 202 $ - $ 202 Those assets as of September 30, 2015 which are measured at fair value on a recurring basis are as follows: Category Used for Fair Value Measurement Level 1 Level 2 Level 3 Total (Dollars in Thousands) Assets: Securities available for sale: U.S. Government and agency obligations $ - $ 18,712 $ - $ 18,712 Mortgage-backed securities - U.S. Government agencies - 58,712 - 58,712 FHLMC preferred stock 59 - - 59 Total $ 59 $ 77,424 $ - $ 77,483 Certain assets are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). The Company measures impaired loans and real estate owned at fair value on a non-recurring basis. Impaired Loans Collateral dependent impaired loans are based on the fair value of the collateral which is based on appraisals and would be categorized as Level 2 measurement. In some cases, adjustments are made to the appraised values for various factors including the age of the appraisal, age of the comparable included in the appraisal, and known changes in the market and in the collateral. These adjustments are based upon unobservable inputs, and therefore, the fair value measurement has been categorized as a Level 3 measurement. These loans are reviewed for impairment and written down to their net realizable value by charges against the allowance for loan losses. The collateral underlying these loans had a fair value of $19.4 million and $16.8 million at September 30, 2016 and 2015, respectively. Real Estate Owned Once an asset is determined to be uncollectible, the underlying collateral is generally repossessed and reclassified to foreclosed real estate and repossessed assets. These repossessed assets are carried at the lower of cost or fair value of the collateral, based on independent appraisals, less cost to sell and would be categorized as Level 2 measurement. In some cases, adjustments are made to the appraised values for various factors including age of the appraisal, age of the comparables included in the appraisal, and known changes in the market and in the collateral. Thus the evaluations are based upon unobservable inputs, and therefore, the fair value measurement has been categorized as a Level 3 measurement.

Business Combinations [Abstract]
PENDING ACQUISITION	19. PENDING ACQUISITION On June 2, 2016, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Polonia Bancorp. Pursuant to the Merger Agreement, Polonia Bancorp will merge with and into the Company (the “Merger”) and Polonia Bancorp’s wholly owned subsidiary, Polonia Bank, a federally chartered savings bank, will merge with and into the Bank. Pursuant to the Merger Agreement, at the effective time of the Merger, each outstanding share of Polonia Bancorp common stock will be converted into the right to receive, at the election of the Polonia Bancorp shareholder (subject to certain conditions, including conditions relating to pro-ration): (i) 0.7591 of a share of Company common stock (the “Exchange Ratio”) or (ii) $11.28 in cash (the “Per Share Cash Consideration” and collectively with the Exchange Ratio, the “Merger Consideration”). The election of shares of Company stock or cash will be subject to pro-ration such that 50% of the issued and outstanding shares of Polonia Bancorp common stock will be exchanged for Company common stock and 50% will be exchanged for cash. Options to purchase Polonia Bancorp common stock outstanding at the effective time of the Merger will fully vest and be exchanged for a cash payment equal to the difference, if positive, between the Per Share Cash Consideration under the Merger Agreement and the corresponding exercise price of such option, subject to prior receipt of any required regulatory approvals. The Merger Consideration is subject to adjustment in certain limited situations. In the event that Polonia Bancorp Consolidated Stockholders’ Equity, as calculated in accordance with the terms of the Merger Agreement, is less than $37.4 million as of the Final Statement Date, as defined in the Merger Agreement, then the Exchange Ratio and the Per Share Cash Consideration will be adjusted downward to reflect the amount of the difference between $37.4 million and the Polonia Bancorp Consolidated Stockholders’ Equity. The Merger Consideration is subject to potential upward adjustment to reflect the after-tax impact of certain recoveries experienced by Polonia Bancorp, if any, achieved prior to the Final Statement Date as specified in the Merger Agreement. In such situation, the Exchange Ratio and the Per Share Cash Consideration, as they may have been adjusted downward as noted above, will be correspondingly adjusted to reflect the amount of such after-tax recoveries.

Allowance for Loan Losses	Allowance for Loan Losses — The allowance for loan losses represents the amount which management estimates is adequate to provide for probable losses inherent in its loan portfolio as of the Consolidated Statement of Financial Condition date. The allowance method is used in providing for loan losses. Accordingly, all loan losses are charged to the allowance, and all recoveries are credited to it. The allowance for loan losses is established through a provision for loan losses charged to operations. The provision for loan losses is based on management’s periodic evaluation of individual loans, economic factors, past loan loss experience, changes in the composition and volume of the portfolio, and other relevant factors, both qualitative and quantitative. The estimates used in determining the adequacy of the allowance for loan losses, including the amounts and timing of future cash flows expected on impaired loans, are particularly susceptible to changes in the near term. Impaired loans are loans for which it is not probable to collect all amounts due according to the contractual terms of the loan agreements. Management individually evaluates such loans for impairment and does not aggregate loans by major risk classifications. Factors considered by management in determining impairment include payment status and collateral value. The amount of impairment for impaired loans is determined by the difference between the present value of the expected cash flows related to the loans, using the original interest rate, and their recorded value, or as a practical expedient in the case of collateralized loans, the difference between the fair value of the collateral and the recorded amount of the loans. When foreclosure is probable, impairment is measured based on the fair value of the collateral. Mortgage loans and consumer loans are comprised of large groups of smaller balance homogeneous loans which are evaluated for impairment collectively. Loans that experience insignificant payment delays, which are defined as less than 90 days, generally are not classified as impaired. Management determines the significance of payment delays on a case-by-case basis taking into consideration all of the circumstances surrounding the loan and the borrower including the length of the delay, the borrower’s prior payment record, and the amount of shortfall in relation to the principal and interest owed.
Real Estate Owned	Real Estate Owned —
Federal Home Loan Bank of Pittsburgh ("FHLB") Stock	Federal Home Loan Bank of Pittsburgh (“FHLB”) Stock – The Company is a member of the Federal Home Loan Bank of Pittsburgh and as such, is required to maintain a minimum investment in stock of the Federal Home Loan Bank that varies with the level of advances outstanding with the Federal Home Loan Bank. The stock is bought from and sold to the Federal Home Loan Bank based upon its $100 par value. The stock does not have a readily determinable fair value and as such is classified as restricted stock, carried at cost and evaluated for impairment by management. The stock’s value is determined by the ultimate recoverability of the par value rather than by recognizing temporary declines. The determination of whether the par value will ultimately be recovered is influenced by criteria such as the following: (a) the significance of the decline in net assets of the Federal Home Loan Bank as compared to the capital stock amount and the length of time this situation has persisted; (b) commitments by the Federal Home Loan Bank to make payments required by law or regulation and the level of such payments in relation to the operating performance; (c) the impact of legislative and regulatory changes on the customer base of the Federal Home Loan Bank; and (d) the liquidity position of the Federal Home Loan Bank. The Federal Home Loan Bank continues to report net income, continues to declare quarter cash dividends and had its Aaa bond rating affirmed by Moody’s and AA+ rating affirmed by Standard and Poor’s during 2015 and remain unchanged as of September 30, 2016.With consideration given to these factors, management concluded that the stock was not impaired at September 30, 2016 or 2015.

Income Taxes	Income Taxes— In evaluating the Company’s ability to recover deferred tax assets, management considers all available positive and negative evidence, including past operating results and forecast of future taxable income. In determining future taxable income, management makes assumptions for the amount of taxable income, the reversal of temporary differences and the implementation of feasible and prudent tax planning strategies. These assumptions require management to make judgments about future taxable income and are consistent with the plans and estimates the Company uses to manage the business. Any reduction in estimated future taxable income may require management to record an additional valuation allowance against the deferred tax assets. An increase in the valuation allowance would result in additional income tax expense in the period and could have a significant impact on our future earnings.

Interest Rate Swap Agreement	Interest Rate Swap Agreement The gain or loss on a derivative designated and qualifying as a fair value hedging instrument, as well as the offsetting gain or loss on the hedged item attributable to the risk being hedged, is recognized currently in earnings in the same accounting period. The effective portion of the gain or loss on a derivative designated and qualifying as a cash flow hedging instrument is initially reported as a component of other comprehensive income and subsequently reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The ineffective portion of the gain or loss on the derivative instrument, if any, is recognized currently in earnings. For cash flow hedges, the net settlement (upon close-out or termination) that offsets changes in the value of the hedged debt is deferred and amortized into net interest income over the life of the hedged debt. For fair value hedges, the net settlement (upon close-out or termination) that offsets changes in the value of the loans adjusts the basis of the loans and is deferred and amortized to loan interest income over the life of the loans. The portion, if any, of the net settlement amount that did not offset changes in the value of the hedged asset or liability is recognized immediately in noninterest income. Interest rate derivative financial instruments receive hedge accounting treatment only if they are designated as a hedge and are expected to be, and are, effective in substantially reducing interest rate risk arising from the assets and liabilities identified as exposing the Company to risk. Those derivative financial instruments that do not meet specified hedging criteria would be recorded at fair value, with changes in fair value recorded in income. If periodic assessment indicates derivatives no longer provide an effective hedge, the derivative contracts would be closed out and settled, or classified as a trading activity.
