Accounting Policies [Abstract]
Summary of Significant Accounting Policies	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation The unaudited consolidated financial statements include the accounts of Kearny Financial Corp. (the “Company”), its wholly-owned subsidiary, Kearny Bank (the “Bank”) and the Bank’s wholly-owned subsidiaries, CJB Investment Corp., KFS Insurance Services, Inc. and Millington Savings Service Corp. The Company conducts its business principally through the Bank. Management prepared the unaudited consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”), including the elimination of all significant inter-company accounts and transactions during consolidation. 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 (loss) 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 six-month periods ended December 31, 2020 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, 2020 was derived from the Company’s 2020 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 2020 Annual Report on Form 10-K. Risks and Uncertainties As previously disclosed, on March 11, 2020, the World Health Organization declared the outbreak of COVID-19 a global pandemic. The COVID-19 pandemic has adversely affected, and may continue to adversely affect, local, national and global economic activity. The spread of the outbreak has caused significant disruptions to the U.S. economy, significant reductions in the targeted federal funds rate and has disrupted banking and other financial activity in the areas in which the Company operates. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted to, among other provisions, provide emergency assistance for individuals, families and businesses affected by the COVID-19 pandemic. On December 27, 2020 the 2021 Consolidated Appropriations Act, was enacted as part of an omnibus spending bill for the 2021 federal fiscal year, included provisions intended to provide additional aid to those impacted by the pandemic. Reductions in interest rates and other effects of the COVID-19 pandemic may continue to materially and adversely affect the Company's financial condition and results of operations in future periods. It is unknown how long the adverse conditions associated with the COVID-19 pandemic will last and what the complete financial effect will be to the Company. It is possible that estimates made in the financial statements could be materially and adversely impacted as a result of these conditions, including estimates regarding expected credit losses on loans receivable, impairment of investment securities and impairment of goodwill. Although the Company continues to operate while taking steps to ensure the safety of employees and clients, COVID-19 could also potentially create widespread business continuity issues for the Company. The extent to which the COVID-19 pandemic will continue to impact the Company’s business, financial condition and results of operations in future periods will depend on future developments, including the scope and duration of the pandemic, the efficacy and adoption of COVID-19 vaccines and actions taken by governmental authorities and other third parties in response to the pandemic, as well as further actions the Company may take as may be required by government authorities or that the Company determines is in the best interests of its employees and clients. There is no certainty that such measures will be sufficient to mitigate the risks posed by the pandemic. Adoption of New Accounting Standards On July 1, 2020, the Company adopted ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”, which replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (CECL) methodology. The Company adopted ASU 2016-13 using a modified retrospective approach. Results for reporting periods beginning after July 1, 2020 are presented under Topic 326, while prior period amounts continue to be reported in accordance with previously applicable GAAP. At adoption, the Company increased its allowance for credit losses by $20.2 million, comprised of $19.6 million for loans receivable and $536,000 for unfunded commitments. Upon adoption the Company recorded a cumulative effect adjustment that reduced stockholders’ equity by $14.2 million, net of tax. Allowance for Credit Losses The allowance for credit losses represents the estimated amount considered necessary to cover lifetime expected credit losses inherent in financial assets at the balance sheet date. The measurement of expected credit losses is applicable to loans receivable and securities measured at amortized cost. It also applies to off-balance sheet credit exposures such as loan commitments and unused lines of credit. The allowance is established through a provision for credit losses that is charged against income. The methodology for determining the allowance for credit losses is considered a critical accounting policy by management because of the high degree of judgment involved, the subjectivity of the assumptions used, and the potential for changes in the forecasted economic environment that could result in changes to the amount of the recorded allowance for credit losses. The allowance for credit losses is reported separately as a contra-asset on the consolidated statement of financial condition. The expected credit loss for unfunded lending commitments and unfunded loan commitments is reported on the Consolidated Statement of Financial Condition in other liabilities while the provision for credit losses related to unfunded commitments is reported in other non-interest expense. Allowance for Credit Losses on Loans Receivable The allowance for credit losses on loans is deducted from the amortized cost basis of the loan to present the net amount expected to be collected. Expected losses are evaluated and calculated on a collective, or pooled, basis for those loans which share similar risk characteristics. At each reporting period, the Company evaluates whether loans within a pool continue to exhibit similar risk characteristics. If the risk characteristics of a loan change, such that they are no longer similar to other loans in the pool, the Company will evaluate the loan with a different pool of loans that share similar risk characteristics. If the loan does not share risk characteristics with other loans, the Company will evaluate the loan on an individual basis. The Company evaluates the pooling methodology at least annually. Loans are charged off against the allowance for credit losses when the Company believes the balances to be uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged off or expected to be charged off. The Company has chosen to segment its portfolio consistent with the manner in which it manages credit risk. Such segments include multi-family, nonresidential mortgage, commercial business, construction, one- to four-family residential, home equity and consumer. For most segments the Company calculates estimated credit losses using a probability of default and loss given default methodology, the results of which are applied to the aggregated discounted cash flow of each individual loan within the segment. The point in time probability of default and loss given default are then conditioned by macroeconomic scenarios to incorporate reasonable and supportable forecasts that affect the collectability of the reported amount. The Company estimates the allowance for credit losses on loans via a quantitative analysis which considers relevant available information from internal and external sources related to past events and current conditions, as well as the incorporation of reasonable and supportable forecasts. The Company evaluates a variety of factors including third party economic forecasts, industry trends and other available published economic information in arriving at its forecasts. After the reasonable and supportable forecast period, the Company reverts, on a straight-line basis, to average historical losses. Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications unless either of the following applies: management has a reasonable expectation at the reporting date that a troubled debt restructuring will be executed with an individual borrower or the renewal option is included in the original or modified contract at the reporting date and are not unconditionally cancelable by the Company. Also included in the allowance for credit losses on loans are qualitative reserves to cover losses that are expected but, in the Company’s assessment, may not be adequately represented in the quantitative analysis or the forecasts described above. Factors that the Company considers include changes in lending policies and procedures, business conditions, the nature and size of the portfolio, portfolio concentrations, the volume and severity of past due loans and non-accrual loans, the effect of external factors such as competition, legal and regulatory requirements, among others. Furthermore, the Company considers the inherent uncertainty in quantitative models that are built upon historical data. Individually Evaluated Loans On a case-by-case basis, the Company may conclude that a loan should be evaluated on an individual basis based on its disparate risk characteristics. When the Company determines that a loan no longer shares similar risk characteristics with other loans in the portfolio, the allowance will be determined on an individual basis using the present value of expected cash flows or, for collateral-dependent loans, the fair value of the collateral as of the reporting date, less estimated selling costs, as applicable. If the fair value of the collateral is less than the amortized cost basis of the loan, the Company will charge off the difference between the fair value of the collateral, less costs to sell at the reporting date and the amortized cost basis of the loan. Acquired Loans Acquired loans are included in the Company's calculation of the allowance for credit losses. How the allowance on an acquired loan is recorded depends on whether or not it has been classified as a Purchased Credit Deteriorated (“PCD”) loan. PCD loans are loans acquired at a discount that is due, in part, to credit quality. PCD loans are accounted for in accordance with ASC Subtopic 326-20 and are initially recorded at fair value as determined by the sum of the present value of expected future cash flows and an allowance for credit losses at acquisition. The allowance for PCD loans is recorded through a gross-up effect, while the allowance for acquired non-PCD loans is recorded through provision expense, consistent with originated loans. Thus, the determination of which loans are PCD and non-PCD can have a significant impact on the accounting for these loans. Subsequent to acquisition, the allowance for PCD loans will generally follow the same estimation, provision and charge-off process as non-PCD acquired and originated loans. Allowance for Credit Losses on Off-Balance Sheet Commitments The Company is required to include unfunded commitments that are expected to be funded in the future within the allowance calculation, other than those that are unconditionally cancelable. To arrive at that reserve, the reserve percentage for each applicable segment is applied to the unused portion of the expected commitment balance and is multiplied by the expected funding rate. To determine the expected funding rate, the Company uses a historical utilization rate for each segment. As noted above, the allowance for credit losses on unfunded loan commitments is included in other liabilities on the consolidated statement of financial condition and the related credit expense is recorded in other non-interest expense in the consolidated statements of income. Allowance for Credit Losses on Held to Maturity Securities The Company’s entire portfolio of held to maturity securities consists of municipal bonds which are highly rated by major rating agencies and have a long history of no credit losses. In estimating the net amount expected to be collected for held to maturity securities in an unrealized loss position, a historical loss based method is utilized. Allowance for Credit Losses on Available for Sale Securities For available for sale securities in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more than likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. For securities available for sale that do not meet the above criteria, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, the Company considers the extent to which fair value is less than amortized cost, any changes to the rating by a rating agency, and adverse conditions related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of the cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income, net of tax. The Company elected the practical expedient of zero loss estimates for securities issued by U.S. government entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rate by major agencies and have a long history of no credit losses. Changes in the allowance for credit losses are recorded as provision for, or reversal of, credit loss expense. Losses are charged against the allowance when management believes the uncollectibility of an available for sale security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Accrued Interest Receivable The Company made an accounting policy election to exclude accrued interest receivable from the amortized cost basis of loans, available for sale securities, and held to maturity securities. Accrued interest receivable on loans is reported as a component of accrued interest receivable on the Consolidated Statement of Financial Condition, totaled $15.5 million at December 31, 2020 and is excluded from the estimate of credit losses.

Earnings Per Share [Abstract]
Net Income Per Common Share (EPS)	2. 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 schedule shows the Company’s earnings per share calculations for the periods presented: Three Months Ended December 31, Six Months Ended December 31, 2020 2019 2020 2019 Net income $ 16,948 $ 10,652 $ 28,327 $ 22,022 Weighted average number of common shares outstanding - basic 85,120 82,831 85,564 83,794 Effect of dilutive securities 3 45 2 41 Weighted average number of common shares outstanding - diluted 85,123 82,876 85,566 83,835 Basic earnings per share $ 0.20 $ 0.13 $ 0.33 $ 0.26 Diluted earnings per share $ 0.20 $ 0.13 $ 0.33 $ 0.26 Stock options for 3,280,648 and 3,115,000 shares of common stock were not considered in computing diluted earnings per share at December 31, 2020 and December 31, 2019, respectively, because they were considered anti-dilutive.

MSB Financial Corporation [Member]
Acquisition of MSB Financial Corp.	4. ACQUISITION OF MSB FINANCIAL CORP. O n July 10, 2020, the Company completed its acquisition of MSB Financial Corp. (“MSB”), and its subsidiary Millington Bank. In accordance with the merger agreement, approximately $9.8 million in cash and 5,853,811 shares of Company common stock were distributed to former MSB shareholders in exchange for their shares of MSB common stock. The assets acquired and liabilities assumed have been accounted for under the acquisition method of accounting. The assets and liabilities, both tangible and intangible, were recorded at their fair values as of July 10, 2020 based on management’s best estimate using the information available as of the merger date. The application of the acquisition method of accounting resulted in the recognition of bargain purchase gain of $3.1 million and a core deposit intangible of $690,000. During the quarter ended December 31, 2020 the Company completed all MSB tax returns and determined that there were no material adjustments to the balance of deferred income tax assets or bargain purchase gain associated with the MSB acquisition. The Company recorded the assets acquired and liabilities assumed through the merger at fair value as summarized in the following table: As Recorded by MSB Fair Value Adjustments As Recorded at Acquisition (In Thousands) Cash paid for acquisition $ 9,830 Value of stock issued 45,133 Total purchase price $ 54,963 Cash and cash equivalents $ 14,126 $ - $ 14,126 Investment securities 4,000 (510 ) (a) 3,490 Loans receivable 537,589 (7,345 ) (b) 530,244 Allowance for loan losses (6,037 ) 6,037 (c) - Premises and equipment 7,698 (3,221 ) (d) 4,477 FHLB stock 3,345 - 3,345 Accrued interest receivable 1,701 - 1,701 Core deposit intangibles - 690 (e) 690 Bank owned life insurance 14,663 - 14,663 Deferred income taxes, net 1,729 2,152 (f) 3,881 Other assets 4,830 495 (g) 5,325 Total assets acquired $ 583,644 $ (1,702 ) $ 581,942 Deposits $ 458,392 $ 1,786 (h) $ 460,178 FHLB borrowings 62,900 - 62,900 Advance payments by borrowers for taxes 794 - 794 Other liabilities 810 (756 ) (i) 54 Total liabilities assumed $ 522,896 $ 1,030 $ 523,926 Net assets acquired $ 58,016 Bargain purchase gain $ (3,053 ) Explanation of certain fair value related adjustments: (a) Represents the fair value adjustments on investment securities. (b) Represents the fair value adjustments on the net book value of loans, which includes an interest rate mark and credit mark adjustment and the reversal of deferred fees/costs and premiums. (c) Represents the elimination of MSB’s allowance for loan losses. (d) Represents the fair value adjustments to reflect the fair value of land and buildings and premises and equipment, which will be amortized on a straight-line basis over the estimated useful lives of the individual assets. (e) Represents the intangible assets recorded to reflect the fair value of core deposits. The core deposit asset was recorded as an identifiable intangible asset and will be amortized on an accelerated basis over the estimated average life of the deposit base. (f) Represents an adjustment to net deferred tax assets resulting from the fair value adjustments related to the acquired assets, liabilities assumed and identifiable intangible assets recorded. (g) Represents an adjustment to other assets acquired. (h) Represents fair value adjustments on time deposits, which will be treated as a reduction of interest expense over the remaining term of the time deposits. (i) Represents an adjustment to other liabilities assumed. The fair value of loans acquired from MSB was estimated using cash flow projections based on the remaining maturity and repricing terms. Cash flows were adjusted by estimating future credit losses and the rate of prepayments. Projected monthly cash flows were then discounted to present value using a risk-adjusted market rate for similar loans. There was no carryover of MSB’s allowance for loan losses associated with the loans that were acquired. For information regarding purchased loans which have been determined to be PCD, refer to Note 8, Loans Receivable. The core deposit intangible asset recognized is being amortized over its estimated useful life of approximately 10 years utilizing the sum-of-the-years digits method. The fair value of retail demand and interest bearing deposit accounts was assumed to approximate the carrying value as these accounts have no stated maturity and are payable on demand. The fair value of time deposits was estimated by discounting the contractual future cash flows using market rates offered for time deposits of similar remaining maturities.

Available for sale securities are evaluated to determine if a decline in fair value below the amortized cost basis has resulted from a credit loss or other factors. An impairment related to credit factors would be recorded through an allowance for credit losses. The allowance is limited to the amount by which the security’s amortized cost basis exceeds the fair value. An impairment that has not been recorded through an allowance for credit losses shall be recorded through other comprehensive income, net of applicable taxes. Investment securities will be written down to fair value through the consolidated statement of income when management intends to sell, or may be required to sell, the securities before they recover in value. The issuers of these securities continue to make timely principal and interest payments and none of these securities were past due or were placed in nonaccrual status at December 31, 2020. Management believes that the unrealized losses on these securities are a function of changes in market interest rates and credit spreads, not changes in credit quality. Therefore, no allowance for credit losses was recorded at December 31, 2020. At December 31, 2020, the Company’s entire portfolio of held to maturity securities consists of municipal bonds which are highly rated by major rating agencies and have a long history of no credit losses. None of the securities in the Company’s portfolio of held to maturity municipal bonds were in an unrealized loss position. The Company continually monitors the municipal bond sector of the market and reviews collectability including such factors as the financial condition of the issuers including credit ratings in effect as of the reporting period.

Loans that become 90 days past due, but are well secured and in the process of collection, may remain on accrual status. Nonaccrual loans are generally returned to accrual status when all payments due are brought current and we expect to receive all remaining P&I payments owed substantially in accordance with the terms of the loan agreement. Payments received in cash on nonaccrual loans, including both the principal and interest portions of those payments, are generally applied to reduce the carrying value of the loan. The Company did not recognize interest income on non-accrual loans during the three and six months ended December 31, 2020 and December 31, 2019.

If the borrower is experiencing financial difficulties and a concession has been made at the time of such modification, the loan is classified as a TDR. At December 31, 2020, the Company had TDRs totaling $19.6 million. The allowance for credit losses associated with the TDRs presented in the tables below totaled $209,000 and $8,000 as of December 31, 2020 and June 30, 2020, respectively. As of December 31, 2020, there were no significant commitments to lend additional funds to borrowers whose loans had been restructured in a TDR.

During the three months ended December 31, 2020 there was one troubled debt restructuring default totaling $488,000. During the three and six months ended December 31, 2019, there were no troubled debt restructuring defaults. Loan modifications generally involve a reduction in interest rates and/or extension of maturity dates and also may include step up interest rates in their modified terms which will impact their weighted average yield in the future. The residential mortgage loan which qualified as a TDR during the six months ended December 31, 2020, capitalized prior past due amounts and modified the loan’s repayment terms. In March 2020, various regulatory agencies, including the Board of Governors of the Federal Reserve System (the “FRB”) and the Federal Deposit Insurance Corporation (the “FDIC”) , issued an interagency statement on loan modifications and reporting for financial institutions working with c ustomers affected by COVID-19. The interagency statement was effective immediately and impacted accounting for loan modifications. The agencies confirmed with the staff of the FASB that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief, are not to be consider ed TDRs. This includes short-term modifications such as payment deferrals, fee waivers, extension of repayment terms, or other delays in payment that are insignificant. Provisions of the CARES Act largely mirrored the provisions of the interagency statement, providing that modified loans were not to be considered TDRs if they were performing at December 31, 2019 and other consideration s set forth in the in teragency statements were met. Borrowers considered current are those that are less than 30 days past due at the time a modification program is implemented or at Decembe r 31, 2019. On December 27, 2020, the 2021 Consolidated Appropriations Act was signed into law. The $900 billion relief package includes legislation that extends certain relief provisions of the CARES Act that were set to expire on December 31, 2020. The CARES Act permitted financial institutions to suspend TDR assessment and reporting requirements under GAAP for loan modifications. This new legislation extends this relief to the earlier of 60 days after the national emergency declared by the President is terminated or January 1, 2022. As of December 31, 2020, the Company had 37 non-TDR modified loans totaling approximately $33.2 million. The following table sets forth the composition of these loans by loan segments as of December 31, 2020: December 31, 2020 # of Loans (1) Balance (1) (Dollars In Thousands) Commercial loans: Multi-family mortgage loans 9 $ 18,247 Nonresidential mortgage 2 5,913 Commercial business 5 1,314 Total commercial loans 16 25,474 One- to four-family residential mortgage 20 7,664 Consumer loans: Home equity loans 1 39 Total 37 $ 33,177 (1) Includes loans acquired in conjunction with the Company’s acquisition of MSB on July 10, 2020. Individually Analyzed Loans Effective July 1, 2020, individually analyzed loans include loans which do not share similar risk characteristics with other loans. TDR’s will generally be evaluated for individual impairment, however, after a period of sustained repayment performance which permits the credit to be returned to accrual status, a TDR would generally be removed from individual impairment analysis and returned to its corresponding pool. As of December 31, 2020, the carrying value of individually analyzed loans totaled $71.5 million, of which $58.7 million were considered collateral dependent. For collateral dependent loans where management has determined that foreclosure of the collateral is probable, or where the borrower is experiencing financial difficulty and repayment of the loan is to be provided substantially through the operation or sale of the collateral, the ACL is measured based on the difference between the fair value of the collateral, less costs to sell, and the amortized cost basis of the loan as of the measurement date. See Note 15 for additional disclosure regarding fair value of individually analyzed collateral dependent loans.

The Company analyzes loans individually to classify the loans as to credit risk. The Company uses the following definitions for risk ratings: Pass – Loans that are well protected by the current net worth and paying capacity of the obligor (or guarantors, if any) or by the fair value, less cost to acquire and sell, of any underlying collateral in a timely manner. Special Mention – Loans which do not currently expose the Company to a sufficient degree of risk to warrant an adverse classification but have some credit deficiencies or other potential weaknesses. Substandard – Loans which are inadequately protected by the paying capacity and net worth of the obligor or the collateral pledged, if any. Substandard assets include those characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Doubtful – Loans which have all of the weaknesses inherent in those classified as Substandard, with the added characteristic that the weaknesses present make collection or liquidation in full highly questionable and improbable, on the basis of currently existing facts, conditions and values. Loss – Loans which considered uncollectible or of so little value that their continuance as assets is not warranted. The following table presents the risk category of loans as of December 31, 2020 by loan segment and vintage year: Term Loans by Origination Year for Fiscal Years ended June 30, 2021 2020 2019 2018 2017 Prior Revolving Loans Total (In Thousands) Multi-family mortgage: Pass $ 129,953 $ 260,622 $ 412,587 $ 402,970 $ 383,315 $ 458,752 $ - $ 2,048,199 Special Mention - - - - 1,851 1,070 - 2,921 Substandard - - - 6,170 10,226 8,967 - 25,363 Doubtful - - - - - - - - Total multi-family mortgage 129,953 260,622 412,587 409,140 395,392 468,789 - 2,076,483 Non-residential mortgage: Pass 41,110 86,629 56,444 69,847 276,965 512,294 6,238 1,049,527 Special Mention - - 23,520 - 980 4,524 - 29,024 Substandard - - - 9,165 24,903 11,076 - 45,144 Doubtful - - - - - - - - Total non-residential mortgage 41,110 86,629 79,964 79,012 302,848 527,894 6,238 1,123,695 Commercial business: Pass 29,506 47,411 4,466 20,468 7,093 14,342 68,640 191,926 Special Mention 1,115 1,640 267 2,370 978 15 166 6,551 Substandard - 124 216 1,597 105 1,334 157 3,533 Doubtful - - - - - - - - Total commercial business 30,621 49,175 4,949 24,435 8,176 15,691 68,963 202,010 Construction loans: Pass 6,534 20,680 17,702 21,449 14,239 1,523 5,735 87,862 Special Mention - - - - - - - - Substandard - - - - - 2,536 - 2,536 Doubtful - - - - - - - - Total construction loans 6,534 20,680 17,702 21,449 14,239 4,059 5,735 90,398 Residential mortgage: Pass 154,973 181,649 98,598 98,970 157,949 591,450 375 1,283,964 Special Mention - - 1,246 - - 708 - 1,954 Substandard 952 1,408 683 - 570 15,820 - 19,433 Doubtful - - - - - - - - Total residential mortgage 155,925 183,057 100,527 98,970 158,519 607,978 375 1,305,351 Home equity loans: Pass 356 3,754 6,516 3,805 3,189 19,166 27,556 64,342 Special Mention - - - - - 166 - 166 Substandard - - - - 66 724 - 790 Doubtful - - - - - - - - Total home equity loans 356 3,754 6,516 3,805 3,255 20,056 27,556 65,298 Other consumer loans Pass 504 536 775 266 145 1,717 72 4,015 Special Mention - - - - - - - - Substandard - - - - - - 1 1 Doubtful - - - - - 5 102 107 Other consumer loans 504 536 775 266 145 1,722 175 4,123 Total loans $ 365,003 $ 604,453 $ 623,020 $ 637,077 $ 882,574 $ 1,646,189 $ 109,042 $ 4,867,358 The following table presents, under previously applicable GAAP, the risk category of loans as of June 30, 2020 by loan segment: June 30, 2020 Multi-Family Mortgage Non- Residential Mortgage Commercial Business Construction Residential Mortgage Home Equity Loans Other Consumer Total (In Thousands) Pass $ 2,055,520 $ 932,202 $ 132,818 $ 20,961 $ 1,258,246 $ 81,120 $ 3,979 $ 4,484,846 Special Mention 1,086 4,373 2,585 - 981 157 5 9,187 Substandard 2,962 24,278 3,385 - 13,795 1,643 6 46,069 Doubtful - - - - - - 1 1 Total loans $ 2,059,568 $ 960,853 $ 138,788 $ 20,961 $ 1,273,022 $ 82,920 $ 3,991 $ 4,540,103 Purchased Credit Deteriorated Loans Loans acquired in a business combination after July 1, 2020 are recorded in accordance with ASC Topic 326, after which acquired loans are separated into two types. PCD loans are acquired loans that, as of the acquisition date, have experienced a more-than-insignificant deterioration in credit quality since origination. Non-PCD loans are acquired loans that have experienced no or insignificant deterioration in credit quality since origination. To distinguish between the two types of acquired loans, the Company evaluates risk characteristics that have been determined to be indicators of deteriorated credit quality. The determining criteria may involve loan specific characteristics such as payment status, debt service coverage or other changes in creditworthiness since the loan was originated, while others are relevant to recent economic conditions, such as borrowers in industries impacted by the pandemic. As part of the acquisition of MSB, the Company purchased loans, for which there was, at acquisition, evidence of more than insignificant deterioration of credit quality since origination. The carrying amount of those loans is as follows: At July 10, 2020 (In Thousands) Purchase price of PCD loans at acquisition $ 69,415 Allowance for credit losses at acquisition (3,901 ) Non-credit discount at acquisition (167 ) Amortized cost of acquired PCD loans at acquisition $ 65,347 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 December 31, 2020, we held one single-family property in other real estate owned with an aggregate carrying value of $178,000 that was acquired through a foreclosure on a residential mortgage loan. As of that same date, we held nine residential mortgage loans with aggregate carrying values totaling $1.7 million which were in the process of foreclosure. As of June 30, 2020, we held one single-family property in other real estate owned with an aggregate carrying value of $178,000 that was acquired through a foreclosure on a residential mortgage loan. As of that same date, we held nine residential mortgage loans with aggregate carrying values totaling $1.9 million which were in the process of foreclosure. The States of New Jersey and New York have issued executive orders and enacted legislation declaring moratoriums on removing individuals from a residential property as a result of an eviction or foreclosure proceeding. The New Jersey order will be in effect until two months after the Governor has declared an end to the COVID-19 health crisis. The New York law, which places a moratorium on evictions for tenants who have endured COVID-related hardship and on foreclosures, will be in effect until at least May 1, 2021. As a result, since March 28, 2020, the Company has temporarily suspended residential property foreclosure sales and evictions. On September 4, 2020, the Centers for Disease Control and Prevention (“CDC”) imposed a nationwide temporary federal moratorium on residential evictions due to nonpayment of rent, for qualified tenants. The national eviction moratorium took effect after the expiration of eviction protections established by the CARES Act and was scheduled to extend through December 31, 2020, but was extended legislatively through January 31, 2021. On January 20, 2021, the CDC announced its intent to extend the existing eviction moratorium order through March 31, 2021.

Allowance for Loan Losses

Allowance for Loan Losses	6 Months Ended

Receivables [Abstract]
Allowance for Credit Losses	9. ALLOWANCE FOR CREDIT LOSSES Adoption of Topic 326 On July 1, 2020, the Company adopted ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”, which replaces the incurred loss methodology with an expected loss methodology, referred to as the “CECL” methodology. See Note 1, Summary of Significant Accounting Policies for additional information on the adoption of Topic 326. Allowance for Credit Losses on Loans Receivable The following tables present the balance of the allowance for credit losses at December 31, 2020 and June 30, 2020. For the three months and six months ended December 31, 2020, the balance of the allowance for credit losses is based on the CECL methodology, as noted above. For the year ended June 30, 2020, the allowance for loan losses is based upon the calculation methodology as described in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2020.

Derivative Instruments and Hedging Activities	12. 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 positions. Fair Values of Derivative Instruments on the Statement of Financial Condition The tables below present the fair value of the Company’s derivative financial instruments as well as their classification on the Statement of Financial Condition as of December 31, 2020 and June 30, 2020: December 31, 2020 Asset Derivatives Liability Derivatives Location Fair Value Location Fair Value (In Thousands) Derivatives designated as hedging instruments: Interest rate contracts Other assets $ 216 Other liabilities $ 12,293 Total $ 216 $ 12,293 June 30, 2020 Asset Derivatives Liability Derivatives Location Fair Value Location Fair Value (In Thousands) Derivatives designated as hedging instruments: Interest rate contracts Other assets $ 235 Other liabilities $ 18,177 Total $ 235 $ 18,177 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 December 31, 2020, the Company had a total of 13 interest rate swaps and caps with a total notional amount of $1.19 billion hedging specific wholesale funding positions. 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 six months ended December 31, 2020, the Company had $2.2 million and $4.6 million, respectively, of reclassifications to interest expense. During the next twelve months, the Company estimates that $6.6 million will be reclassified as an increase in interest expense. The tables below present the pre-tax effects of the Company’s derivative instruments on the Consolidated Statements of Income for the three and six months ended December 31, 2020 and 2019: Three Months Ended December 31, 2020 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 contracts $ 1,389 Interest expense $ (2,217 ) Total $ 1,389 $ (2,217 ) Six Months Ended December 31, 2020 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 contracts $ 1,278 Interest expense $ (4,589 ) Total $ 1,278 $ (4,589 ) Three Months Ended December 31, 2019 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 contracts $ 2,679 Interest expense $ 836 Total $ 2,679 $ 836 Six Months Ended December 31, 2019 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 contracts $ 920 Interest expense $ 2,207 Total $ 920 $ 2,207 Offsetting Derivatives The tables below present a gross presentation, the effects of offsetting, and a net presentation of the Company’s derivatives in the Consolidated Statements of Financial Condition as of December 31, 2020 and June 30, 2020, 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 December 31, 2020, 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 $13.0 million. As required under the enforceable master netting arrangement with its derivatives counterparties, at December 31, 2020, the Company posted financial collateral of $12.3 million that was not included as offsetting amount. In addition to the derivative instruments noted above, the Company’s pipeline of loans held for sale at December 31, 2020 and June 30, 2020, included $62.3 million and $127.2 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.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	15. FAIR VALUE OF FINANCIAL INSTRUMENTS In January 2016, the FASB issued ASU 2016-01, “Financial Instruments”. Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability or inputs that are derived principally from, or corroborated by, market data by correlation or other means. 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. Assets Measured on a Recurring Basis: The following methods and significant assumptions were used to estimate the fair values of the Company’s assets measured at fair value on a recurring basis at December 31, 2020 and June 30, 2020: Investment Securities Available for Sale The Company’s available for sale investment securities are reported at fair value utilizing Level 2 inputs. For these securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the securities’ terms and conditions, among other things. From time to time, the Company validates prices supplied by the independent pricing service by comparison to prices obtained from third-party sources or derived using internal models. Derivatives 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. Those assets measured at fair value on a recurring basis are summarized below: December 31, 2020 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total (In Thousands) Assets: Debt securities available for sale: Obligations of state and political subdivisions - 47,763 - 47,763 Asset-backed securities - 255,407 - 255,407 Collateralized loan obligations - 196,685 - 196,685 Corporate bonds - 167,168 - 167,168 Trust preferred securities - 2,866 - 2,866 Total debt securities - 669,889 - 669,889 Mortgage-backed securities available for sale: Collateralized mortgage obligations - 20,510 - 20,510 Residential pass-through securities - 705,991 - 705,991 Commercial pass-through securities - 299,503 - 299,503 Total mortgage-backed securities - 1,026,004 - 1,026,004 Total securities available for sale $ - $ 1,695,893 $ - $ 1,695,893 Interest rate contracts - 216 - 216 Total assets $ - $ 1,696,109 $ - $ 1,696,109 Liabilities: Interest rate contracts $ - $ 12,293 $ - $ 12,293 Total liabilities $ - $ 12,293 $ - $ 12,293 June 30, 2020 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total (In Thousands) Assets: Debt securities available for sale: Obligations of state and political subdivisions - 54,054 - 54,054 Asset-backed securities - 172,447 - 172,447 Collateralized loan obligations - 193,788 - 193,788 Corporate bonds - 143,639 - 143,639 Trust preferred securities - 2,627 - 2,627 Total debt securities - 566,555 - 566,555 Mortgage-backed securities available for sale: Collateralized mortgage obligations - 30,903 - 30,903 Residential pass-through securities - 561,954 - 561,954 Commercial pass-through securities - 226,291 - 226,291 Total mortgage-backed securities - 819,148 - 819,148 Total securities available for sale - 1,385,703 - 1,385,703 Interest rate contracts - 235 - 235 Total assets $ - $ 1,385,938 $ - $ 1,385,938 Liabilities: Interest rate contracts $ - $ 18,177 $ - $ 18,177 Total liabilities $ - $ 18,177 $ - $ 18,177 Assets Measured on a Non-Recurring Basis: The following methods and assumptions were used to estimate the fair values of the Company’s assets measured at fair value on a non-recurring basis at December 31, 2020 and June 30, 2020: Collateral Dependent Individually Analyzed / Impaired Loans: The fair value of collateral dependent loans that are individually analyzed or were previously deemed impaired is determined based upon the appraised fair value of the underlying collateral, less costs to sell. Such collateral primarily consists of real estate and, to a lesser extent, other business assets. Management may also adjust appraised values to reflect estimated market value declines or apply other discounts to appraised values resulting from its knowledge of the collateral. Internal valuations may be utilized to determine the fair value of other business assets. For non-collateral-dependent loans, management estimates fair value using discounted cash flows based on inputs that are largely unobservable and instead reflect management’s own estimates of the assumptions as a market participant would in pricing such loans. Collateral dependent individually analyzed / impaired loans are considered a Level 3 valuation by the Company. Other Real Estate Owned Other real estate owned is recorded at estimated fair value, less estimated selling costs when acquired, thus establishing a new cost basis. Fair value is generally based on independent appraisals. These appraisals include adjustments to comparable assets based on the appraisers’ market knowledge and experience. When an asset is acquired, the excess of the loan balance over fair value, less estimated selling costs, is charged to the allowance for credit losses. If further declines in the estimated fair value of the asset occur, a write-down is recorded through expense. The valuation of foreclosed assets is subjective in nature and may be adjusted in the future because of changes in economic conditions. Those assets measured at fair value on a non-recurring basis are summarized below: December 31, 2020 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total (In Thousands) Collateral dependent loans: Residential mortgage $ - $ - $ 1,900 $ 1,900 Non-residential mortgage - - 3,375 3,375 Total $ - $ - $ 5,275 $ 5,275 Other real estate owned, net: Residential mortgage $ - $ - $ 178 $ 178 Total $ - $ - $ 178 $ 178 June 30, 2020 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 $ - $ - $ 2,339 $ 2,339 Non-residential mortgage - - 2,282 2,282 Commercial business - - 129 129 Total $ - $ - $ 4,750 $ 4,750 Other real estate owned, net: Residential mortgage - - 178 178 Total $ - $ - $ 178 $ 178 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: December 31, 2020 Fair Value Valuation Techniques Unobservable Input Range Weighted Average (In Thousands) Collateral dependent loans: Residential mortgage $ 1,900 Market valuation of underlying collateral (1) Adjustments to reflect current conditions/selling costs (2) 7% - 11% 8.50 % Non-residential mortgage 3,375 Market valuation of underlying collateral (1) Adjustments to reflect current conditions/selling costs (2) 9% - 11% 9.93 % Total $ 5,275 Other real estate owned, net: Residential mortgage $ 178 Market valuation of underlying collateral (3) Adjustments to reflect current conditions/selling costs (2) 6.00% 6.00 % Total $ 178 June 30, 2020 Fair Value Valuation Techniques Unobservable Input Range Weighted Average (In Thousands) Impaired loans: Residential mortgage $ 2,339 Market valuation of underlying collateral (1) Adjustments to reflect current conditions/selling costs (2) 7% - 9% 8.17 % Non-residential mortgage 2,282 Market valuation of underlying collateral (1) Adjustments to reflect current conditions/selling costs (2) 9% - 12% 10.27 % Commercial business 129 Market valuation of underlying collateral (1) Adjustments to reflect current conditions/selling costs (2) 0% - 0% 0.00 % Total $ 4,750 Other real estate owned, net: Residential mortgage 178 Market valuation of underlying collateral (3) Adjustments to reflect current conditions/selling costs (2) 6.00% 6.00 % Total $ 178 (1) The fair value of impaired loans is generally determined based on an independent appraisal of the fair value of a loan’s underlying collateral. (2) The fair value basis of impaired loans and other real estate owned is adjusted to reflect management’s estimates of selling costs including, but not necessarily limited to, real estate brokerage commissions and title transfer fees. (3) The fair value basis of other real estate owned is generally determined based upon the lower of an independent appraisal of the property’s fair value or the applicable listing price or contracted sales price. At December 31, 2020, collateral dependent loans valued using Level 3 inputs comprised loans with principal balances totaling $6.0 million and valuation allowances of $725,000 reflecting fair values of $5.3 million. By comparison, at June 30, 2020, under previously applicable GAAP, impaired loans valued using Level 3 inputs comprised loans with principal balances totaling $4.8 million and valuation allowances of $89,000 reflecting fair values of $4.8 million. Once a loan is foreclosed, the fair value of the other real estate owned continues to be evaluated based upon the fair value of the repossessed real estate originally securing the loan. At December 31, 2020 and June 30, 2020, the Company held other real estate owned totaling $178,000 whose carrying value was written down utilizing Level 3 inputs. The following tables present the carrying amount, fair value, and placement in the fair value hierarchy of the Company’s financial instruments as of December 31, 2020 and June 30, 2020: December 31, 2020 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 $ 129,694 $ 129,694 $ 129,694 $ - $ - Investment securities available for sale 1,695,893 1,695,893 - 1,695,893 - Investment securities held to maturity 29,549 31,063 - 31,063 - Loans held-for-sale 12,601 13,129 - 13,129 - Net loans receivable 4,765,248 4,808,589 - - 4,808,589 FHLB Stock 45,578 - - - - Interest receivable 19,826 19,826 - 4,301 15,525 Interest rate contracts 216 216 - 216 - Financial liabilities: Deposits 5,312,613 5,325,183 3,346,649 - 1,978,534 Borrowings 865,651 899,960 - - 899,960 Interest payable on deposits 327 327 190 - 137 Interest payable on borrowings 1,554 1,554 - - 1,554 Interest rate contracts 12,293 12,293 - 12,293 - June 30, 2020 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 $ 180,967 $ 180,967 $ 180,967 $ - $ - Investment securities available for sale 1,385,703 1,385,703 - 1,385,703 - Investment securities held to maturity 32,556 34,069 - 34,069 - Loans held-for-sale 20,789 21,550 - 21,550 - Net loans receivable 4,461,070 4,462,232 - - 4,462,232 FHLB Stock 58,654 - - - - Interest receivable 17,373 17,373 4 4,154 13,215 Interest rate contracts 235 235 - 235 - Financial liabilities: Deposits 4,430,282 4,449,877 2,589,886 - 1,859,991 Borrowings 1,173,165 1,215,529 - - 1,215,529 Interest payable on deposits 395 395 295 - 100 Interest payable on borrowings 1,723 1,723 - - 1,723 Interest rate contracts 18,177 18,177 - 18,177 - Commitments. The fair value of commitments to fund credit lines and originate or participate in loans held in portfolio or loans held for sale 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, including those relating to loans held for sale that are considered derivative instruments for financial statement reporting purposes, the 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. 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 fair 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 and insurance. 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.

Revenue From Contract With Customer [Abstract]
Revenue Recognition	17. REVENUE RECOGNITION Effective July 1, 2018, the Company adopted ASU 2014-09 Revenue from Contracts with Customers The Company, using a modified retrospective transition approach, determined that there was no cumulative effect adjustment to retained earnings as a result of adopting the new standard, nor did the standard have a material impact on our consolidated financial statements including the timing or amounts of revenue recognized. All of the Company’s revenue from contracts with customers within the scope of ASC 606 is recognized within non-interest income. The following table presents the Company’s sources of non-interest income for the three and six months ended December 31, 2020 and 2019. Sources of revenue outside the scope of ASC 606 are noted as such. Three Months Ended Six Months Ended December 31, December 31, 2020 2019 2020 2019 (In Thousands) (In Thousands) Non-interest income: Deposit-related fees and charges $ 385 $ 463 $ 734 $ 939 Loan-related fees and charges (1) 1,511 1,682 2,238 2,674 Gain (loss) on sale and call of securities (1) 813 11 436 (3 ) Gain on sale of loans (1) 2,378 668 4,268 1,273 Loss on sale and write down of other real estate owned - (28 ) - (28 ) Income from bank owned life insurance (1) 1,596 1,576 3,192 3,156 Electronic banking fees and charges (interchange income) 404 293 809 611 Bargain purchase gain (1) - - 3,053 - Other income (1) 67 (111 ) 157 (106 ) Total non-interest income $ 7,154 $ 4,554 $ 14,887 $ 8,516 (1) Not within the scope of ASC 606. A description of the Company’s revenue streams accounted for under ASC 606 is as follows: Service Charges on Deposit Accounts The Company earns fees from deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which include services such as ATM use fees, stop payment charges, statement rendering, and ACH fees, are recognized at the time the transaction is executed at the point in the time the Company fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer’s account balance. Gains/Losses on Sales of OREO The Company records a gain or loss from the sale of OREO when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. Gain/Losses on the sales of OREO falls within the scope of ASC 606, if the Company finances the transaction. Under ASC 606, if the Company finances the sale of OREO to the buyer, the Company is required to assess whether the buyer is committed to perform their obligations under the contract and whether the collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Company adjusts the transaction price and related gain (loss) on sale if a significant financing component is present. Generally, the Company does not finance the sale of OREO properties. Interchange Income The Company earns interchange fees from debit and credit card holder transactions conducted through various payment networks. Interchange fees from cardholder transactions are recognized daily, concurrently with the transaction processing services provided by an outsourced technology solution.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Dec. 31, 2020
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The unaudited consolidated financial statements include the accounts of Kearny Financial Corp. (the “Company”), its wholly-owned subsidiary, Kearny Bank (the “Bank”) and the Bank’s wholly-owned subsidiaries, CJB Investment Corp., KFS Insurance Services, Inc. and Millington Savings Service Corp. The Company conducts its business principally through the Bank. Management prepared the unaudited consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”), including the elimination of all significant inter-company accounts and transactions during consolidation.
Basis of Presentation	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 (loss) 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 six-month periods ended December 31, 2020 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, 2020 was derived from the Company’s 2020 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 2020 Annual Report on Form 10-K.
Risk and Uncertainties	Risks and Uncertainties As previously disclosed, on March 11, 2020, the World Health Organization declared the outbreak of COVID-19 a global pandemic. The COVID-19 pandemic has adversely affected, and may continue to adversely affect, local, national and global economic activity. The spread of the outbreak has caused significant disruptions to the U.S. economy, significant reductions in the targeted federal funds rate and has disrupted banking and other financial activity in the areas in which the Company operates. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted to, among other provisions, provide emergency assistance for individuals, families and businesses affected by the COVID-19 pandemic. On December 27, 2020 the 2021 Consolidated Appropriations Act, was enacted as part of an omnibus spending bill for the 2021 federal fiscal year, included provisions intended to provide additional aid to those impacted by the pandemic. Reductions in interest rates and other effects of the COVID-19 pandemic may continue to materially and adversely affect the Company's financial condition and results of operations in future periods. It is unknown how long the adverse conditions associated with the COVID-19 pandemic will last and what the complete financial effect will be to the Company. It is possible that estimates made in the financial statements could be materially and adversely impacted as a result of these conditions, including estimates regarding expected credit losses on loans receivable, impairment of investment securities and impairment of goodwill. Although the Company continues to operate while taking steps to ensure the safety of employees and clients, COVID-19 could also potentially create widespread business continuity issues for the Company. The extent to which the COVID-19 pandemic will continue to impact the Company’s business, financial condition and results of operations in future periods will depend on future developments, including the scope and duration of the pandemic, the efficacy and adoption of COVID-19 vaccines and actions taken by governmental authorities and other third parties in response to the pandemic, as well as further actions the Company may take as may be required by government authorities or that the Company determines is in the best interests of its employees and clients. There is no certainty that such measures will be sufficient to mitigate the risks posed by the pandemic.
Adoption of New Accounting Standards	Adoption of New Accounting Standards On July 1, 2020, the Company adopted ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”, which replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (CECL) methodology. The Company adopted ASU 2016-13 using a modified retrospective approach. Results for reporting periods beginning after July 1, 2020 are presented under Topic 326, while prior period amounts continue to be reported in accordance with previously applicable GAAP. At adoption, the Company increased its allowance for credit losses by $20.2 million, comprised of $19.6 million for loans receivable and $536,000 for unfunded commitments. Upon adoption the Company recorded a cumulative effect adjustment that reduced stockholders’ equity by $14.2 million, net of tax.
Allowance for Credit Losses	Allowance for Credit Losses The allowance for credit losses represents the estimated amount considered necessary to cover lifetime expected credit losses inherent in financial assets at the balance sheet date. The measurement of expected credit losses is applicable to loans receivable and securities measured at amortized cost. It also applies to off-balance sheet credit exposures such as loan commitments and unused lines of credit. The allowance is established through a provision for credit losses that is charged against income. The methodology for determining the allowance for credit losses is considered a critical accounting policy by management because of the high degree of judgment involved, the subjectivity of the assumptions used, and the potential for changes in the forecasted economic environment that could result in changes to the amount of the recorded allowance for credit losses. The allowance for credit losses is reported separately as a contra-asset on the consolidated statement of financial condition. The expected credit loss for unfunded lending commitments and unfunded loan commitments is reported on the Consolidated Statement of Financial Condition in other liabilities while the provision for credit losses related to unfunded commitments is reported in other non-interest expense. Allowance for Credit Losses on Loans Receivable The allowance for credit losses on loans is deducted from the amortized cost basis of the loan to present the net amount expected to be collected. Expected losses are evaluated and calculated on a collective, or pooled, basis for those loans which share similar risk characteristics. At each reporting period, the Company evaluates whether loans within a pool continue to exhibit similar risk characteristics. If the risk characteristics of a loan change, such that they are no longer similar to other loans in the pool, the Company will evaluate the loan with a different pool of loans that share similar risk characteristics. If the loan does not share risk characteristics with other loans, the Company will evaluate the loan on an individual basis. The Company evaluates the pooling methodology at least annually. Loans are charged off against the allowance for credit losses when the Company believes the balances to be uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged off or expected to be charged off. The Company has chosen to segment its portfolio consistent with the manner in which it manages credit risk. Such segments include multi-family, nonresidential mortgage, commercial business, construction, one- to four-family residential, home equity and consumer. For most segments the Company calculates estimated credit losses using a probability of default and loss given default methodology, the results of which are applied to the aggregated discounted cash flow of each individual loan within the segment. The point in time probability of default and loss given default are then conditioned by macroeconomic scenarios to incorporate reasonable and supportable forecasts that affect the collectability of the reported amount. The Company estimates the allowance for credit losses on loans via a quantitative analysis which considers relevant available information from internal and external sources related to past events and current conditions, as well as the incorporation of reasonable and supportable forecasts. The Company evaluates a variety of factors including third party economic forecasts, industry trends and other available published economic information in arriving at its forecasts. After the reasonable and supportable forecast period, the Company reverts, on a straight-line basis, to average historical losses. Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications unless either of the following applies: management has a reasonable expectation at the reporting date that a troubled debt restructuring will be executed with an individual borrower or the renewal option is included in the original or modified contract at the reporting date and are not unconditionally cancelable by the Company. Also included in the allowance for credit losses on loans are qualitative reserves to cover losses that are expected but, in the Company’s assessment, may not be adequately represented in the quantitative analysis or the forecasts described above. Factors that the Company considers include changes in lending policies and procedures, business conditions, the nature and size of the portfolio, portfolio concentrations, the volume and severity of past due loans and non-accrual loans, the effect of external factors such as competition, legal and regulatory requirements, among others. Furthermore, the Company considers the inherent uncertainty in quantitative models that are built upon historical data. Individually Evaluated Loans On a case-by-case basis, the Company may conclude that a loan should be evaluated on an individual basis based on its disparate risk characteristics. When the Company determines that a loan no longer shares similar risk characteristics with other loans in the portfolio, the allowance will be determined on an individual basis using the present value of expected cash flows or, for collateral-dependent loans, the fair value of the collateral as of the reporting date, less estimated selling costs, as applicable. If the fair value of the collateral is less than the amortized cost basis of the loan, the Company will charge off the difference between the fair value of the collateral, less costs to sell at the reporting date and the amortized cost basis of the loan. Acquired Loans Acquired loans are included in the Company's calculation of the allowance for credit losses. How the allowance on an acquired loan is recorded depends on whether or not it has been classified as a Purchased Credit Deteriorated (“PCD”) loan. PCD loans are loans acquired at a discount that is due, in part, to credit quality. PCD loans are accounted for in accordance with ASC Subtopic 326-20 and are initially recorded at fair value as determined by the sum of the present value of expected future cash flows and an allowance for credit losses at acquisition. The allowance for PCD loans is recorded through a gross-up effect, while the allowance for acquired non-PCD loans is recorded through provision expense, consistent with originated loans. Thus, the determination of which loans are PCD and non-PCD can have a significant impact on the accounting for these loans. Subsequent to acquisition, the allowance for PCD loans will generally follow the same estimation, provision and charge-off process as non-PCD acquired and originated loans. Allowance for Credit Losses on Off-Balance Sheet Commitments The Company is required to include unfunded commitments that are expected to be funded in the future within the allowance calculation, other than those that are unconditionally cancelable. To arrive at that reserve, the reserve percentage for each applicable segment is applied to the unused portion of the expected commitment balance and is multiplied by the expected funding rate. To determine the expected funding rate, the Company uses a historical utilization rate for each segment. As noted above, the allowance for credit losses on unfunded loan commitments is included in other liabilities on the consolidated statement of financial condition and the related credit expense is recorded in other non-interest expense in the consolidated statements of income. Allowance for Credit Losses on Held to Maturity Securities The Company’s entire portfolio of held to maturity securities consists of municipal bonds which are highly rated by major rating agencies and have a long history of no credit losses. In estimating the net amount expected to be collected for held to maturity securities in an unrealized loss position, a historical loss based method is utilized. Allowance for Credit Losses on Available for Sale Securities For available for sale securities in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more than likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. For securities available for sale that do not meet the above criteria, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, the Company considers the extent to which fair value is less than amortized cost, any changes to the rating by a rating agency, and adverse conditions related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of the cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income, net of tax. The Company elected the practical expedient of zero loss estimates for securities issued by U.S. government entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rate by major agencies and have a long history of no credit losses. Changes in the allowance for credit losses are recorded as provision for, or reversal of, credit loss expense. Losses are charged against the allowance when management believes the uncollectibility of an available for sale security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Accrued Interest Receivable The Company made an accounting policy election to exclude accrued interest receivable from the amortized cost basis of loans, available for sale securities, and held to maturity securities. Accrued interest receivable on loans is reported as a component of accrued interest receivable on the Consolidated Statement of Financial Condition, totaled $15.5 million at December 31, 2020 and is excluded from the estimate of credit losses.
