BASIS OF PRESENTATION The accompanying unaudited consolidated financial statements were prepared in accordance with instructions for Form 10-Q and Regulation S-X and do not include information or footnotes necessary for a complete presentation of financial condition, income, comprehensive income, changes in stockholders’ equity and cash flows in conformity with GAAP. However, in the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the unaudited consolidated financial statements have been included. The results of operations for the three-month and nine-month periods ended March 31, 2018 are not necessarily indicative of the results that may be expected for the entire fiscal year or any other period. The data in the consolidated statement of financial condition for June 30, 2017 was derived from the Company’s 2017 Annual Report on Form 10-K. That data, along with the interim unaudited financial information presented in the consolidated statements of financial condition, income, comprehensive income, changes in stockholders’ equity and cash flows should be read in conjunction with the audited consolidated financial statements, including the notes thereto, included in the Company’s 2017 Annual Report on Form 10-K.

Earnings Per Share [Abstract]
Net Income Per Common Share (EPS)	3. NET INCOME PER COMMON SHARE (“EPS”) Basic EPS is based on the weighted average number of common shares actually outstanding including both vested and unvested restricted stock awards adjusted for Employee Stock Ownership Plan (“ESOP”) shares not yet committed to be released. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock, such as outstanding stock options, were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the Company. Diluted EPS is calculated by adjusting the weighted average number of shares of common stock outstanding to include the effect of contracts or securities exercisable or which could be converted into common stock, if dilutive, using the treasury stock method. Shares issued and reacquired during any period are weighted for the portion of the period they were outstanding. The following is a reconciliation of the numerators and denominators of the basic and diluted earnings per share computations: Three Months Ended Nine Months Ended March 31, 2018 March 31, 2018 Income (Numerator) Shares (Denominator) Per Share Amount Income (Numerator) Shares (Denominator) Per Share Amount (In Thousands, Except Per Share Data) (In Thousands, Except Per Share Data) Net income $ 5,377 $ 11,878 Basic earnings per share, income available to common stockholders $ 5,377 75,492 $ 0.07 $ 11,878 77,452 $ 0.15 Effect of dilutive securities: Stock options 47 58 $ 5,377 75,539 $ 0.07 $ 11,878 77,510 $ 0.15 Three Months Ended Nine Months Ended March 31, 2017 March 31, 2017 Income (Numerator) Shares (Denominator) Per Share Amount Income (Numerator) Shares (Denominator) Per Share Amount (In Thousands, Except Per Share Data) (In Thousands, Except Per Share Data) Net income $ 4,068 $ 14,199 Basic earnings per share, income available to common stockholders $ 4,068 84,542 $ 0.05 $ 14,199 85,326 $ 0.17 Effect of dilutive securities: Stock options 82 76 $ 4,068 84,624 $ 0.05 $ 14,199 85,402 $ 0.17 During the three and nine months ended March 31, 2018, the average number of options which were considered anti-dilutive totaled approximately 3,290,000 and 3,290,000, respectively. During the three and nine months ended March 31, 2017, the average number of options which were considered anti-dilutive totaled approximately 3,290,000 and 1,452,883, respectively.

Acquisition of Clifton Bancorp Inc	5. ACQUISITION OF CLIFTON BANCORP INC. O n April 2, 2018, the Company completed its acquisition of Clifton Bancorp Inc. (“Clifton”), the parent company of Clifton Savings Bank, a federally chartered stock savings bank. At the time of closing, Clifton had $1.7 billion in total assets, including $1.2 billion in net loans receivable and $357.9 million in securities, and $1.4 billion in total liabilities, including $945.0 million in deposits and $421.4 million in borrowings. The deposits acquired from Clifton are held across a network of 12 branches located in New Jersey throughout Bergen, Passaic, Hudson, and Essex counties. Given the initial accounting for this business combination is incomplete, management is not yet able to disclose the preliminary fair value of the assets acquired and liabilities assumed. Clifton’s stockholders’ equity totaled approximately $272.0 million at the time of closing. Under the terms of the merger agreement, each outstanding share of Clifton common stock was exchanged for 1.191 shares of the Company’s common stock, resulting in the Company issuing 25.4 million shares of common stock to CSBK stockholders in conjunction with the merger’s closing. Based on the closing date of April 2, 2018, the Company’s unaudited consolidated financial statements included in this report on Form 10-Q do not reflect the changes attributable to the Company’s acquisition of Clifton.

RECENT ACCOUNTING PRONOUNCEMENTS In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) ASU 2014-09, Revenue from Contracts with Customers (Topic 606) Subsequently, the FASB issued the following standards related to ASU 2014-09: ASU 2016-08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations”; ASU 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing”; ASU 2016-11, “Revenue Recognition (Topic 605) and Derivatives and Hedging (Topic 815): Rescission of SEC Guidance Because of Accounting Standards Updates 2014-09 and 2014-16 Pursuant to Staff Announcements at the March 3, 2016 EITF Meeting”; ASU 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients”; and ASU 2017-05, “Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets.” These amendments are intended to improve and clarify the implementation guidance of ASU 2014-09 and have the same effective date as the original standard. The Company’s main source of revenue is comprised of net interest income on interest earning assets and liabilities and non-interest income. The scope of this ASU explicitly excludes net interest income as well as other revenues associated with financial assets and liabilities, including loans, leases, securities, certain insurance revenues and derivatives. While there were no material changes related to the timing or amount of revenue recognition, the Company will continue to evaluate the need for additional disclosures. In January 2016, the FASB issued ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments 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 SEC filers, the amendments are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (i.e. modified retrospective approach). The Company has begun its evaluation of this ASU including the potential impact on its consolidated financial statements. The extent of change is indeterminable at this time as it will be dependent upon portfolio composition and credit quality at the adoption date, as well as economic conditions and forecasts at that time. Upon adoption, any impact to the allowance for credit losses, currently allowance for loan and lease losses, will have an offsetting impact on retained earnings. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment In March 2017, ASU 2017-07, Compensation-Retirement Benefits (Topic715), In March 2017, ASU 2017-08 Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20), In May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting, Adoption of New Accounting Standards In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities, In February 2018, the FASB issued ASU 2018-02, Income Statement-Reporting Comprehensive income (Topic 220), Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.

Impairment of Securities	10. IMPAIRMENT OF SECURITIES The following two tables summarize the fair values and gross unrealized losses within the available for sale and held to maturity portfolios at March 31, 2018 and June 30, 2017. The gross unrealized and unrecognized losses, presented by security type, represent temporary impairments of value within each portfolio as of the dates presented. Temporary impairments within the available for sale portfolio have been recognized through other comprehensive income as reductions in stockholders’ equity on a tax-effected basis. The tables are followed by a discussion that summarizes the Company’s rationale for recognizing impairments, where applicable, as “temporary” versus those identified as “other-than-temporary”. Such rationale is presented by investment type and generally applies consistently to both the “available for sale” and “held to maturity” portfolios, except where specifically noted.

The number of held to maturity securities with unrecognized losses at June 30, 2017 totaled 90 and included two U.S. agency securities, 44 municipal obligations, seven collateralized mortgage obligations, 34 residential pass-through securities and three commercial pass-through securities. In general, if the fair value of a debt security is less than its amortized cost basis at the time of evaluation, the security is “impaired” and the impairment is to be evaluated to determine if it is other than temporary. The Company evaluates the impaired securities in its portfolio for possible other than temporary impairment (“OTTI”) on at least a quarterly basis. The following represents the circumstances under which an impaired security is determined to be other than temporarily impaired: • When the Company intends to sell the impaired debt security; • When the Company more likely than not will be required to sell the impaired debt security before recovery of its amortized cost (for example, whether liquidity requirements or contractual or regulatory obligations indicate that the security will be required to be sold before a forecasted recovery occurs); or • When an impaired debt security does not meet either of the two conditions above, but the Company does not expect to recover the entire amortized cost of the security. According to applicable accounting guidance for debt securities, this is generally when the present value of cash flows expected to be collected is less than the amortized cost of the security. In the first two circumstances noted above, the amount of OTTI recognized in earnings is the entire difference between the security’s amortized cost basis and its fair value at the balance sheet date. In the third circumstance, however, the OTTI is to be separated into the amount representing the credit loss from the amount related to all other factors. The credit loss component is to be recognized in earnings while the non-credit loss component is to be recognized in other comprehensive income. In these cases, OTTI is generally predicated on an adverse change in cash flows (e.g. principal and/or interest payment deferrals or losses) versus those expected at the time of purchase. The absence of an adverse change in expected cash flows generally indicates that a security’s impairment is related to other “non-credit loss” factors and is thereby generally not recognized as OTTI. The Company considers a variety of factors when determining whether a credit loss exists for an impaired security including, but not limited to: • The length of time and the extent (a percentage) to which the fair value has been less than the amortized cost basis; • Adverse conditions specifically related to the security, an industry, or a geographic area (e.g. changes in the financial condition of the issuer of the security, or in the case of an asset backed debt security, in the financial condition of the underlying loan obligors, including changes in technology or the discontinuance of a segment of the business that may affect the future earnings potential of the issuer or underlying loan obligors of the security or changes in the quality of the credit enhancement); • The historical and implied volatility of the fair value of the security; • The payment structure of the debt security; • Actual or expected failure of the issuer of the security to make scheduled interest or principal payments; • Changes to the rating of the security by external rating agencies; and • Recoveries or additional declines in fair value subsequent to the balance sheet date. At March 31, 2018 and June 30, 2017, the Company held no securities for which credit-related OTTI had been recognized in earnings based on the Company’s analysis and determination that the impairment reported in the tables above was “temporary” in nature as of both dates. The rationale for making that determination is based on several factors which are generally shared among the various sectors represented in the Company’s available for sale and held to maturity portfolios. The most significant of these is the general mitigation of credit risk arising from the U.S. government, agency and GSE guarantees supporting the Company’s mortgage-backed securities, U.S. agency debt securities and asset-backed securities. While not supported by such guarantees, the Company’s collateralized loan obligations represent tranches within a larger investment vehicle that reallocate cash flows and credit risk among the individual tranches comprised within that vehicle. Through this structure, the Company is afforded significant protection against the risk that the securities within this sector will be adversely impacted by borrowers defaulting on the underlying loans. In the absence of the guarantor or structural protections noted above, the securities within the other sectors of the Company’s securities portfolio, including its municipal obligations, corporate bonds and single-issuer trust preferred securities are generally issued by credit-worthy entities with the ability and resources to fully meet their financial obligations. The Company regularly monitors the historical cash flows and financial strength of all issuers and/or guarantors to confirm that security impairment, where applicable, is not due to an actual or expected adverse change in security cash flows that would result in the recognition of credit-related OTTI. With credit risk being mitigated in the manner outlined above, the unrealized and unrecognized losses on the Company’s securities are due largely to the combined effects of several market-related factors including, most notably, changes in market interest rates and changing market conditions which affect the supply and demand for such securities. Those market conditions may fluctuate over time resulting in certain securities being impaired for periods in excess of 12 months. However, the longevity of such impairment is not necessarily reflective of an expectation for an adverse change in cash flows signifying a credit loss. Consequently, the impairments of value resulting directly from these changing market conditions are considered “noncredit-related” and “temporary” in nature. The Company has the stated ability and intent to “hold until forecasted recovery” those securities so designated at March 31, 2018 and does not intend to sell the temporarily impaired available for sale securities prior to the recovery of their fair value to a level equal to or greater than the Company’s amortized cost. Furthermore, the Company has concluded that the possibility of being required to sell the securities prior to their anticipated recovery is unlikely based upon its strong liquidity, asset quality and capital position as of that date. In light of the factors noted above, the Company does not consider its balance of securities with unrealized and unrecognized losses at March 31, 2018 and June 30, 2017, to be “other-than-temporarily” impaired as of those dates.

Loan Quality and Allowance for Loan Losses	11. LOAN QUALITY AND ALLOWANCE FOR LOAN LOSSES Acquired Credit-Impaired Loans. At March 31, 2018, the remaining outstanding principal balance and carrying amount of acquired credit-impaired loans totaled approximately $589,000 and $378,000, respectively. By comparison, at June 30, 2017, the remaining outstanding principal balance and carrying amount of acquired credit-impaired loans totaled approximately $839,000 and $594,000, respectively. The carrying amount of acquired credit-impaired loans for which interest is not being recognized due to the uncertainty of the cash flows relating to such loans totaled $355,000 and $371,000 at March 31, 2018 and June 30, 2017, respectively. There were no valuation allowances for specifically identified impairment attributable to acquired credit-impaired loans at March 31, 2018 and June 30, 2017, respectively. The following table presents the changes in the accretable yield relating to the acquired credit-impaired loans for the three and nine months ended March 31, 2018 and March 31, 2017. Three Months Ended March 31, 2018 2017 (In Thousands) Beginning balance $ 206 $ 312 Accretion to interest income - (97 ) Disposals - - Reclassifications from nonaccretable difference - - Ending balance $ 206 $ 215 Nine Months Ended March 31, 2018 2017 (In Thousands) Beginning balance $ 215 $ 335 Accretion to interest income (9 ) (101 ) Disposals - (19 ) Reclassifications from nonaccretable difference - - Ending balance $ 206 $ 215 Residential Mortgage Loans in Foreclosure. We may obtain physical possession of one- to four-family real estate collateralizing a residential mortgage loan via foreclosure or through an in-substance repossession. As of March 31, 2018, we held three single-family properties in real estate owned with an aggregate carrying value of $1.1 million that were acquired through foreclosures on residential mortgage loans.

Derivative Instruments and Hedging Activities	14. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES Risk Management Objective of Using Derivatives The Company uses various financial instruments, including derivatives, to manage its exposure to interest rate risk. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to specific wholesale funding positons. Fair Values of Derivative Instruments on the Statement of Financial Condition The table below presents the fair value of the Company’s derivative financial instruments as well as their classification on the Statement of Financial Condition as of March 31, 2018 and June 30, 2017: March 31, 2018 Asset Derivatives Liability Derivatives Location Fair Value Location Fair Value (In Thousands) Derivatives designated as hedging instruments: Interest rate swaps Other assets $ 27,946 Other liabilities $ - Interest rate caps Other assets 118 Other liabilities - Total $ 28,064 $ - June 30, 2017 Asset Derivatives Liability Derivatives Location Fair Value Location Fair Value (In Thousands) Derivatives designated as hedging instruments: Interest rate swaps Other assets $ 7,670 Other liabilities $ 298 Interest rate caps Other assets 140 Other liabilities - Total $ 7,810 $ 298 Cash Flow Hedges of Interest Rate Risk The Company’s objectives in using derivatives are primarily to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company has entered into interest rate swaps and caps as part of its interest rate risk management strategy. These interest rate products are designated as cash flow hedges. As of March 31, 2018, the Company had fifteen interest rate swaps with a notional of $1.2 billion and two interest rate caps with a notional of $75.0 million hedging certain FHLB advances and brokered deposits. For derivatives designated as cash flow hedges, the gain or loss on the derivative is recorded in other comprehensive income, net of tax, and subsequently reclassified into interest expense in the same period during which the hedged transaction affects earnings. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s variable rate wholesale funding positions. During the three and nine months ended March 31, 2018, the Company had $599,000 and $3.3 million, respectively, of reclassifications to interest expense. During the next twelve months, the Company estimates that $4.6 million will be reclassified as a reduction in interest expense. The table below presents the pre-tax effects of the Company’s derivative instruments on the Consolidated Statements of Income and Comprehensive Income for the three and nine months ended March 31, 2018 and 2017: Three Months Ended March 31, 2018 Amount of Gain (Loss) Recognized in OCI on Derivatives Location of Gain (Loss) Reclassified from Accumulated OCI into Income Amount of Gain (Loss) Reclassified from Accumulated OCI into Income (In Thousands) Derivatives in cash flow hedging relationships: Interest rate swaps $ 11,672 Interest expense $ (352 ) Interest rate caps 50 Interest expense (247 ) Total $ 11,722 $ (599 ) Nine Months Ended March 31, 2018 Amount of Gain (Loss) Recognized in OCI on Derivatives Location of Gain (Loss) Reclassified from Accumulated OCI into Income Amount of Gain (Loss) Reclassified from Accumulated OCI into Income (In Thousands) Derivatives in cash flow hedging relationships: Interest rate swaps $ 18,099 Interest expense $ (2,475 ) Interest rate caps 77 Interest expense (806 ) Total $ 18,176 $ (3,281 ) Three Months Ended March 31, 2017 Amount of Gain (Loss) Recognized in OCI on Derivatives Location of Gain (Loss) Reclassified from Accumulated OCI into Income Amount of Gain (Loss) Reclassified from Accumulated OCI into Income (In Thousands) Derivatives in cash flow hedging relationships: Interest rate swaps $ 1,017 Interest expense $ (1,274 ) Interest rate caps 36 Interest expense (219 ) Total $ 1,053 $ (1,493 ) Nine Months Ended March 31, 2017 Amount of Gain (Loss) Recognized in OCI on Derivatives Location of Gain (Loss) Reclassified from Accumulated OCI into Income Amount of Gain (Loss) Reclassified from Accumulated OCI into Income (In Thousands) Derivatives in cash flow hedging relationships: Interest rate swaps $ 26,439 Interest expense $ (4,509 ) Interest rate caps 126 Interest expense (571 ) Total $ 26,565 $ (5,080 ) Offsetting Derivatives The table below presents a gross presentation, the effects of offsetting, and a net presentation of the Company’s derivatives in the Consolidated Statement of Condition as of March 31, 2018 and June 30, 2017, respectively.

The Company also has agreements with its derivative counterparties that contain a provision where if the Company fails to maintain its status as a well-capitalized institution, then the Company could be required to terminate its derivative positions with the counterparty. As of March 31, 2018 and June 30, 2017, the termination value of derivatives in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to those agreements was $0 and $302,000, respectively. As required under the enforceable master netting arrangement with its derivatives counterparties, at March 31, 2018, the Company received financial collateral of $28.2 million that was not included as an offsetting amount. By comparison, at June 30, 2017, the Company received financial collateral of $5.8 million and posted financial collateral in the amount of $1.0 million that were not included as offsetting amounts. In addition to the derivative instruments noted above, the Company’s pipeline of loans held for sale at March 31, 2018 and June 30, 2017, included $9.3 million and $18.4 million, respectively, of “in process” loans whose terms included interest rate locks to borrowers, which are considered free-standing derivative instruments whose fair values are not material to our financial condition or results of operations.

INCOME TAXES The following table presents a reconciliation between the reported income taxes for the periods presented and the income taxes which would be computed by applying the federal income tax rates applicable to those periods. The income tax rate of 28%, applicable to the reported periods in the current year ending June 30, 2018, reflects the transitional effect of a reduction in the Company’s federal income tax rate from 35%, applicable to the prior year ended June 30, 2017, to 21%, applicable to the forthcoming year ending June 30, 2019. The noted decrease in the Company’s federal income tax rate reflects the impact of federal income tax reform that was codified through the passage of the Act on December 22, 2017.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	17. FAIR VALUE OF FINANCIAL INSTRUMENTS The guidance on fair value measurement establishes a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy describes three levels of inputs that may be used to measure fair value: Level 1: Quoted prices in active markets for identical assets or liabilities. Level 2: Observable inputs other than Level 1 prices, such as quoted for similar assets or liabilities; quoted prices in markets that are not active; or 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. In addition, the guidance requires the Company to disclose the fair value for assets and liabilities on both a recurring and non-recurring basis. Those assets and liabilities measured at fair value on a recurring basis are summarized below: March 31, 2018 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total (In Thousands) Debt securities available for sale: U.S. agency securities $ - $ 4,667 $ - $ 4,667 Obligations of state and political subdivisions - 26,733 - 26,733 Asset-backed securities - 182,066 - 182,066 Collateralized loan obligations - 178,342 - 178,342 Corporate bonds - 142,202 - 142,202 Trust preferred securities - 7,485 1,000 8,485 Total debt securities - 541,495 1,000 542,495 Mortgage-backed securities available for sale: Collateralized mortgage obligations - 25,601 - 25,601 Residential pass-through securities - 108,736 - 108,736 Commercial pass-through securities - 7,939 - 7,939 Total mortgage-backed securities - 142,276 - 142,276 Total securities available for sale $ - $ 683,771 $ 1,000 $ 684,771 Derivative instruments Interest rate swaps $ - $ 27,946 $ - $ 27,946 Interest rate caps - 118 - 118 Total derivatives $ - $ 28,064 $ - $ 28,064 June 30, 2017 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total (In Thousands) Debt securities available for sale: U.S. agency securities $ - $ 5,316 $ - $ 5,316 Obligations of state and political subdivisions - 27,740 - 27,740 Asset-backed securities - 162,429 - 162,429 Collateralized loan obligations - 98,154 - 98,154 Corporate bonds - 142,318 - 142,318 Trust preferred securities - 7,540 1,000 8,540 Total debt securities - 443,497 1,000 444,497 Mortgage-backed securities available for sale: Collateralized mortgage obligations - 30,536 - 30,536 Residential pass-through securities - 130,550 - 130,550 Commercial pass-through securities - 8,177 - 8,177 Total mortgage-backed securities - 169,263 - 169,263 Total securities available for sale $ - $ 612,760 $ 1,000 $ 613,760 Derivative instruments: Interest rate swaps $ - $ 7,372 $ - $ 7,372 Interest rate caps - 140 - 140 Total derivatives $ - $ 7,512 $ - $ 7,512 The fair values of securities available for sale (carried at fair value) or held to maturity (carried at amortized cost) are primarily determined by obtaining matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). The Company held one trust preferred security whose fair value of $1.0 million at March 31, 2018 was determined using Level 3 inputs. For the periods ended March 31, 2018 and June 30, 2017, management has been unable to obtain a market quote for this security. Consequently, the security’s fair value as reported at March 31, 2018 and June 30, 2017, is based upon the present value of expected future cash flows assuming the security continues to meet all of its payment obligations and utilizing a discount rate based upon the security’s contractual interest rate. The Company has contracted with a third party vendor to provide periodic valuations for its interest rate derivatives to determine the fair value of its interest rate caps and swaps. The vendor utilizes standard valuation methodologies applicable to interest rate derivatives such as discounted cash flow analysis and extensions of the Black-Scholes model. Such valuations are based upon readily observable market data and are therefore considered Level 2 valuations by the Company. In addition to the financial instruments noted above, at March 31, 2018 and June 30, 2017, the Company’s pipeline of loans held for sale included $9.3 million and $18.4 million, respectively, of “in process” loans whose terms included interest rate locks to borrowers that were paired with a “non-binding” best-efforts commitment to sell the loan to a buyer at a fixed price and within a predetermined timeframe after the sale commitment was established. Those assets and liabilities measured at fair value on a non-recurring basis are summarized below: March 31, 2018 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total (In Thousands) Impaired loans: Residential mortgage $ - $ - $ 4,057 $ 4,057 Non-residential mortgage - - 798 798 Commercial business - - 162 162 Total $ - $ - $ 5,017 $ 5,017 June 30, 2017 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total (In Thousands) Impaired loans: Residential mortgage $ - $ - $ 5,711 $ 5,711 Non-residential mortgage - - 2,126 2,126 Commercial business - - 119 119 Total $ - $ - $ 7,956 $ 7,956 The following table presents additional quantitative information about assets measured at fair value on a non-recurring basis and for which the Company has utilized adjusted Level 3 inputs to determine fair value: March 31, 2018 Fair Value Valuation Techniques Unobservable Input Range Weighted Average (In Thousands) Impaired loans: Residential mortgage $ 4,057 Market valuation of collateral (1) Selling costs (2) 6% - 25% 10.08 % Non-residential mortgage 798 Market valuation of collateral (1) Selling costs (2) 13% - 14% 13.34 % Commercial business 162 Market valuation of collateral (1) Selling costs (2) 12% - 20% 14.47 % Total $ 5,017 June 30, 2017 Fair Value Valuation Techniques Unobservable Input Range Weighted Average (In Thousands) Impaired loans: Residential mortgage $ 5,711 Market valuation of collateral (1) Selling costs (2) 6% - 21% 8.12 % Non-residential mortgage 2,126 Market valuation of collateral (1) Selling costs (2) 0% - 12% 6.93 % Commercial business 119 Market valuation of collateral (1) Selling costs (2) 9% - 20% 12.79 % Total $ 7,956 (1) The fair value of impaired loans is generally determined based on an independent appraisal of the market value of a loan’s underlying collateral. (2) The fair value basis of impaired loans is adjusted to reflect management estimates of selling costs including, but not necessarily limited to, real estate brokerage commissions and title transfer fees. An impaired loan is evaluated and valued at the time the loan is identified as impaired at the lower of cost or market value. Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. Market value is measured based on the value of the collateral securing the loan and is classified at a Level 3 in the fair value hierarchy. Once a loan is identified as individually impaired, management measures impairment in accordance with the FASB’s guidance on accounting by creditors for impairment of a loan with the fair value estimated using the market value of the collateral reduced by estimated disposal costs. Those impaired loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceeds the recorded investments in such loans. Impaired loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly. At March 31, 2018, impaired loans valued using Level 3 inputs comprised loans with principal balances totaling $5.1 million and valuation allowances of $133,000 reflecting fair values of $5.0 million. By comparison, at June 30, 2017, impaired loans valued using Level 3 inputs comprised loans with principal balances totaling $8.2 million and valuation allowances of $199,000 reflecting fair values of $8.0 million. Once a loan is foreclosed, the fair value of the real estate owned continues to be evaluated based upon the market value of the repossessed real estate originally securing the loan. At March 31, 2018 and June 30, 2017, the Company held no real estate owned whose carrying value was written down utilizing Level 3 inputs. The following methods and assumptions were used to estimate the fair value of each class of financial instruments at March 31, 2018 and June 30, 2017: Cash and Cash Equivalents, Interest Receivable and Interest Payable. The carrying amounts for cash and cash equivalents, interest receivable and interest payable approximate fair value because they mature in three months or less. Securities. See the discussion presented above concerning assets measured at fair value on a recurring basis. Loans Receivable. Except for certain impaired loans as previously discussed, the fair value of loans receivable is estimated by discounting the future cash flows, using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities, of such loans. FHLB of New York Stock. The carrying amount of restricted investment in bank stock approximates fair value, and considers the limited marketability of such securities. Deposits. The fair value of demand, savings and club accounts is equal to the amount payable on demand at the reporting date. The fair value of certificates of deposit is estimated using rates currently offered for deposits of similar remaining maturities. The fair value estimates do not include the benefit that results from the low-cost funding provided by deposit liabilities compared to the cost of borrowing funds in the market. Advances from FHLB. Fair value is estimated using rates currently offered for advances of similar remaining maturities. Interest Rate Derivatives. See the discussion presented above concerning assets measured at fair value on a recurring basis. Commitments. The fair value of commitments to fund credit lines and originate or participate in loans is estimated using fees currently charged to enter into similar agreements taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties. For fixed rate loan commitments, fair value also considers the difference between current levels of interest and the committed rates. The carrying value, represented by the net deferred fee arising from the unrecognized commitment, and the fair value, determined by discounting the remaining contractual fee over the term of the commitment using fees currently charged to enter into similar agreements with similar credit risk, is not considered material for disclosure. The carrying amounts and fair values of financial instruments are as follows: March 31, 2018 Carrying Amount Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (In Thousands) Financial assets: Cash and cash equivalents $ 38,283 $ 38,283 $ 38,283 $ - $ - Debt securities available for sale 542,495 542,495 - 541,495 1,000 Mortgage-backed securities available for sale 142,276 142,276 - 142,276 - Debt securities held to maturity 128,011 126,045 - 126,045 - Mortgage-backed securities held to maturity 331,369 325,233 - 325,233 - Loans held-for-sale 2,377 2,377 - 2,377 - Net loans receivable 3,321,121 3,254,183 - - 3,254,183 FHLB Stock 39,112 N/A N/A N/A N/A Interest receivable 13,926 13,926 - 4,197 9,729 Financial liabilities: Deposits (1) 3,067,798 3,056,111 1,657,824 - 1,398,286 Borrowings 852,009 856,046 - - 856,046 Interest payable on borrowings 1,647 1,647 - - 1,647 (1) Includes accrued interest payable on deposits of $696,000 at March 31, 2018.

Limitations. Fair value estimates are made at a specific point in time based on relevant market information and information about the financial instruments. These estimates do not reflect any premium or discount that could result from offering for sale at one time the entire holdings of a particular financial instrument. Because no market value exists for a significant portion of the financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments and other factors. These estimates are subjective in nature, involve uncertainties and matters of judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates. The fair value estimates are based on existing on-and-off balance sheet financial instruments without attempting to value anticipated future business and the value of assets and liabilities that are not considered financial instruments. Other significant assets and liabilities that are not considered financial assets and liabilities include premises and equipment, and advances from borrowers for taxes. In addition, the ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in any of the estimates. Finally, reasonable comparability between financial institutions may not be likely due to the wide range of permitted valuation techniques and numerous estimates which must be made given the absence of active secondary markets for many of the financial instruments. This lack of uniform valuation methodologies introduces a greater degree of subjectivity to these estimated fair values.
