	1. BASIS OF PRESENTATION
	Clifton Bancorp Inc. (the “Company”) is a Maryland corporation incorporated in November 2013 to be the successor to Clifton Savings Bancorp, Inc. (“Clifton Savings Bancorp”) upon completion of the second-step conversion of Clifton Savings Bank (the “Bank”) from the two-tier mutual holding company structure to the stock holding company structure. Clifton MHC was the former mutual holding company for Clifton Savings Bancorp prior to completion of the second-step conversion and owned 16,791,758 shares or approximately 64%, of the outstanding shares of common stock of Clifton Savings Bancorp prior to the second-step conversion. In conjunction with the second-step conversion, Clifton MHC merged into Clifton Savings Bancorp (and ceased to exist), and Clifton Savings Bancorp merged into the Company, with the Company as the surviving entity. The second-step conversion was completed April 1, 2014, at which time the Company sold, for net proceeds of $163.2 million, a total of 17,059,448 shares of common stock at $10.00 per share, including 1,023,566 shares purchased by the Bank’s Employee Stock Ownership Plan. As part of the second-step conversion, each of the existing 9,737,241 outstanding shares of Clifton Savings Bancorp common stock owned by persons other than Clifton MHC was converted into 0.9791 of a share of Company common stock. As a result of the second-step conversion, all share information has been subsequently revised to reflect the 0.9791 exchange ratio.
	The consolidated financial statements include the accounts of the Company, the Company’s wholly-owned subsidiary, Clifton Savings Bank (the “Bank”), and the Bank’s wholly-owned subsidiary, Botany Inc. (“Botany”). Because the Bank’s second-step conversion was completed on April 1, 2014, all financial and other information before that date that is included in this Quarterly Report on Form 10-Q is derived from the consolidated financial statements of Clifton Savings Bancorp. The Company’s business consists principally of investing in securities and the operations of the Bank. Botany’s business consists solely of holding investment and mortgage-backed securities, and Botany is treated under New Jersey tax law as a New Jersey investment company. All significant intercompany accounts and transactions have been eliminated in consolidation.
	The accompanying unaudited consolidated financial statements were prepared in accordance with the instructions for Form 10-Q and Regulation S-X and do not include information or footnotes necessary for a complete presentation of financial condition, results of operations, or cash flows in conformity with accounting principles generally accepted in the United States of America. However, in the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the consolidated financial statements have been included. The results of operations for the three month period ended June 30, 2014 are not necessarily indicative of the results which may be expected for the entire fiscal year or any other period. The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reported periods. Actual results could differ from those estimates. These consolidated financial statements should be read in conjunction with the Clifton Savings Bancorp’s audited consolidated financial statements and related notes thereto for the year ended March 31, 2014, which are included in the Company’s Annual Report on Form 10-K as filed with the Securities and Exchange Commission on June 6, 2014.
	The Company has evaluated events and transactions occurring subsequent to the statement of financial condition date of June 30, 2014, for items that should potentially be recognized or disclosed in these consolidated financial statements. The evaluation was conducted through the date these consolidated financial statements were issued.

Earnings Per Share [Abstract]	'
Earnings Per Share (EPS)	'
	2. EARNINGS PER SHARE (EPS)
	Basic EPS is based on the weighted average number of common shares actually outstanding, and is adjusted for employee stock ownership plan shares not yet committed to be released and deferred compensation obligations required to be settled in shares of Company stock. Unvested restricted stock awards, which contain rights to non-forfeitable dividends, are considered participating securities and the two-class method of computing basic and diluted EPS is applied. 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 (such as stock options) or which could be converted into common stock, if dilutive, using the treasury stock method. Basic and diluted EPS have been determined based on the adjusted numbers of weighted average shares. The calculation of diluted EPS for the three months ended June 30, 2014 and 2013 includes 168,680 and 229,687 incremental shares, respectively, related to outstanding stock options. As a result of the second-step conversion, the 2013 period shares were adjusted to reflect the 0.9791 exchange ratio. Shares issued or retired during any period are weighted for the portion of the period they were outstanding. During the three months ended June 30, 2014 and 2013, no options were antidilutive.

The amortized cost and carrying values shown above are by contractual final maturity. Actual maturities will differ from contractual final maturities due to scheduled monthly payments related to mortgage-backed securities and due to the borrowers having the right to prepay obligations with or without prepayment penalties. The Company’s mortgage-backed securities are generally secured by residential mortgage loans with contractual maturities of 15 years or greater, and multi-family loans with maturities of five to ten years. However, the effective lives of those securities are generally shorter than their contractual maturities due to principal amortization and prepayment of the loans within those securities. Investors in pass-through securities generally share in the receipt of principal repayments on a pro-rata basis as paid by the borrowers.
The age of gross unrealized losses and the fair value of related securities at June 30 and March 31, 2014 were as follows:

Management does not believe that any of the unrealized losses at June 30, 2014 (ten bonds of Government-sponsored enterprises and one municipal bond included in debt securities, and thirty-three FNMA mortgage-backed securities, nine FHLMC mortgage-backed securities, and one GNMA mortgage-backed security) represent an other-than-temporary impairment as they are primarily related to market interest rates and not related to the underlying credit quality of the issuers of the securities. Additionally, the Company and its subsidiaries have the ability, and management has the intent, to hold such securities for the time necessary to recover amortized cost and does not have the intent to sell the securities, and it is more likely than not that it will not have to sell the securities before recovery of their amortized cost.
There were no sales of securities during the three months ended June 30, 2014. During the three months ended June 30, 2013, the proceeds from sales of securities available for sale totaled $4.7 million and the proceeds from sales of securities held to maturity totaled $5.6 million, resulting in gross realized gains of $295,000 and $272,000, respectively, and gross realized losses of $-0- and $1,000, respectively. The remaining principal balance for each of the securities held to maturity sold was less than 15% of the original principal purchased.

	The allowance for loan losses consists of general and unallocated components. For loans that are classified as impaired, a valuation allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component of the allowance covers pools of loans by loan class not considered impaired, as well as smaller balance homogeneous loans, such as one- to four-family real estate, construction real estate, second mortgage loans, home equity lines of credit and passbook loans. These pools of loans are evaluated for loss exposure based upon historical loss rates for each of these categories of loans, adjusted for qualitative factors to reflect current conditions. The qualitative risk factors which include:
	1	Lending policies and procedures, including underwriting standards and collection, charge-off, and recovery practices.
	2	National, regional, and local economic and business conditions, including the value of underlying collateral for collateral dependent loans.
	3	Nature and volume of the portfolio and terms of loans.
	4	Experience, ability, and depth of lending management and staff.
	5	The quality of the Bank’s loan review system.
	6	Volume and severity of past due, classified and nonaccrual loans.
	7	Existence and effect of any concentrations of credit and changes in the level of such concentrations.
	8	Effect of external factors, such as competition and legal and regulatory requirements.
	Each factor is assigned a value to reflect improving, stable or declining conditions based on management’s best judgment using relevant information available at the time of the evaluation. Adjustments to the factors are supported through documentation of changes in conditions in a narrative accompanying the allowance for loan loss calculation.
	An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating losses in the portfolio.
	The evaluation of the adequacy of the allowance is based on an analysis which categorizes the entire loan portfolio by certain risk characteristics. The loan portfolio segments are further disaggregated into the following loan classes, where the risk level for each type is analyzed when determining the allowance for loan losses.
	Real Estate:
	1. One- to Four-Family Loans – consists of loans secured by first liens on either owner occupied or investment properties. These loans can be affected by economic conditions and the value of the underlying properties. The risk is considered relatively low as the Bank has always had conservative underwriting standards and does not have sub-prime loans in its loan portfolio.
	2. Multi-Family Loans – consists of loans secured by multi-family real estate which generally involve a greater degree of risk than one- to four-family residential mortgage loans. These loans can be affected by economic conditions and the value of the underlying properties. The risk is considered relatively low as the Bank believes it has always had conservative underwriting standards.
	3. Commercial Loans – consists of loans secured by commercial real estate which generally involve a greater degree of risk than one- to four-family residential mortgage loans. These loans can be affected by economic conditions and the value of the underlying properties. The risk is considered relatively low as the Bank believes it has always had conservative underwriting standards. These loans are affected by economic conditions to a greater degree than one- to four-family and multi-family loans.
	4. Construction Loans – consists primarily of the financing of construction of one- to four-family properties or construction/permanent loans for the construction of one- to four-family homes to be occupied by the borrower. Construction loans generally are considered to involve a higher degree of risk of loss than long-term financing on improved, occupied real estate due to uncertainty of construction costs. Independent inspections are performed prior to disbursement of loan proceeds as construction progresses to mitigate these risks. These loans are also affected by economic conditions.
	Consumer:
	1. Second Mortgage and Equity Lines of Credit – consists of one- to four-family loans secured by first, second or third liens (when the Bank has the two other lien positions) or, in one instance, a commercial property. These loans are affected by the borrower’s continuing financial stability, and therefore are more likely to be adversely affected by job loss, divorce, illness or personal bankruptcy. The credit risk is considered slightly higher than one- to four-family first lien loans as these loans are also dependent on the value of underlying properties, but in many instances, have the added risk of a subordinate collateral position.
	2. Passbook or Certificate and Other Loans – consists of loans secured by passbook accounts and certificates of deposits and unsecured loans. The passbook or certificate loans have low credit risk as they are fully secured by their collateral. Unsecured loans, included in other loans, are two loans in a New Jersey loan fund and they also are considered a low credit risk.
	The allowance calculation methodology includes further segregation of loan classes into risk rating categories. The borrower’s overall financial condition, repayment sources, guarantors and value of collateral, if appropriate, are evaluated when credit deficiencies arise, such as delinquent loan payments. Credit quality risk ratings include regulatory classifications of special mention, substandard, doubtful and loss. Loans classified as special mention have potential weaknesses that deserve management’s close attention. If uncorrected, the potential weaknesses may result in deterioration of the repayment prospects. Loans classified as substandard have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They include loans that are inadequately protected by the current sound net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans classified as doubtful have all the weaknesses inherent in loans classified as substandard with the added characteristic that collection or liquidation in full, on the basis of current conditions and facts, is highly improbable. Loans classified as a loss are considered uncollectible and are charged to the allowance for loan losses. Non-classified assets are rated as a pass or pass-watch. Pass-watch loans require current oversight or tracking by management generally due to incomplete documentation or monitoring due to previous delinquent status.
	In addition, the Office of the Comptroller of the Currency (the “OCC”), as an integral part of its examination process, periodically reviews the Bank’s loan portfolio and the related allowance for loan losses. The OCC may require the allowance for loan losses to be increased based on its review of information available at the time of the examination.
	The change in the allowance for loan losses for the three months ended June 30, 2014 and 2013 is as follows:

The following table provides information with respect to the Bank’s nonaccrual loans at June 30 and March 31, 2014. Loans are generally placed on nonaccrual status when they become more than 90 days delinquent, or when the collection of principal and, or interest become doubtful. Nonaccrual loans differed from the amount of total loans past due greater than 90 days due to some previously delinquent loans that are currently not more than 90 days delinquent which are maintained on nonaccrual status for a minimum of six months until the borrower has demonstrated the ability to satisfy the loan terms. A loan is returned to accrual status when there is sustained period of repayment performance (generally six months) by the borrower in accordance with the contractual terms of the loan, or in some circumstances, when the factors indicating doubtful collectability no longer exist and the Bank expects repayment of the remaining contractual amounts due.

There were no loans that are past due greater than 90 days that were accruing as of June 30 and March 31, 2014.
A loan is defined as impaired when, based on current information and events, it is probable that a creditor will be unable to collect all amounts due under the contractual terms of the loan agreement. The Company considers one- to four-family mortgage loans and consumer installment loans to be homogeneous and, therefore, does not generally evaluate them individually for impairment, unless they are considered troubled debt restructurings. All other loans are evaluated for impairment on an individual basis.
Impaired loans, none of which had a related allowance at or during the three months ending June 30, 2014 and 2013, and at or for the year ended March 31, 2014, were as follows:

The recorded investment in loans modified in a troubled debt restructuring totaled $724,000 and $523,000, respectively, at June 30 and March 31, 2014, of which $8,000 was 90 days or more past due at both dates. The remaining loans modified were current at the time of the restructuring and have complied with the terms of their restructure agreements at June 30 and March 31, 2014. Loans that were modified in a troubled debt restructuring represent concessions made to borrowers experiencing financial difficulties. The Bank works with these borrowers to modify existing loan terms usually by extending maturities or reducing interest rates. The Bank records an impairment loss, if any, based on the present value of expected future cash flows discounted at the original loan’s effective interest rate. Subsequently, these loans are individually evaluated for impairment.

Fair Value Disclosures [Abstract]	'
Fair Value	'
	6. FAIR VALUE
	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 certain assets and liabilities on both a recurring and non-recurring basis.
	An asset’s or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.
	For assets measured at fair value on a recurring basis, the fair value measurements by level within the fair value hierarchy used at June 30 and March 31, 2014 are as follows:
	Description		Carrying		(Level 1)				(Level 2)				(Level 3)

	There were no liabilities measured at fair value on a recurring or non-recurring basis at June 30, or March 31, 2014.
	The following table presents additional quantitative information about assets measured at fair value on a nonrecurring basis and for which the Company has utilized adjusted Level 3 inputs to determine fair value.
			Fair Value Estimate		Valuation Techniques		Unobservable				Range (Weighted
							Input				Average)
			(Dollars in Thousand)

	Impaired loan		$	177	Market valuation of			Selling costs	(2)			15% (15%)

	-1	Fair value is based on short sale price.
	-2	Includes estimated costs to sell.
	The following information should not be interpreted as an estimate of the fair value of the Company since a fair value calculation is only provided for a limited portion of the Company’s assets and liabilities. Due to a wide range of valuation techniques and the degree of subjectivity used in making the estimates, comparisons between the Company’s disclosures and those of other companies may not be meaningful. The following methods and assumptions were used to estimate the fair values of certain of the Company’s assets and liabilities at June 30 and March 31, 2014.
	Cash and Cash Equivalents, Interest Receivable, Stock Subscription Deposits and Interest Payable (Carried at Cost)
	The carrying amounts reported in the consolidated statements of financial condition for cash and cash equivalents, interest receivable, stock subscription deposits and interest payable approximate their fair values.
	Securities
	The fair value of all securities, whether classified as available for sale (carried at fair value) or held to maturity (carried at amortized cost), is determined by reference to quoted market prices, where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments. Securities are measured on a recurring basis. The fair values of these securities are obtained from prices received from an independent broker. The Company’s broker provides it with prices which are categorized as Level 2 since quoted prices in active markets for identical assets are generally not available. As the Company is responsible for the determination of fair value, it performs monthly analyses on the prices received from the pricing service to determine whether the prices are reasonable estimates of fair value. Specifically, the Company compares the prices received from the pricing service to a secondary pricing source. The Company’s internal price verification procedures and review of fair value methodology documentation provided by third- party pricing services has not historically resulted in adjustment in the prices obtained from the pricing service.
	Loans Receivable (Carried at Cost)
	Fair value 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.
	Impaired Loans (Carried based on Collateral Fair Value or Discounted Cash Flows)
	Impaired loans are those accounted for under ASC Topic 310 “Accounting by Creditors for Impairment of a Loan” in which the Company has measured impairment generally based on either the fair value of the loan’s collateral or discounted cash flows. These assets are included as Level 3 assets.
	Real Estate Owned
	Real estate owned, acquired through foreclosure or deed-in-lieu of foreclosure, is initially recorded at fair value less estimated costs sell and subsequently carried at the lower of such initially recorded amount or current fair value less estimated selling costs. Fair value is estimated through current appraisals by licensed appraiser and as such, foreclosed real estate properties are classified as Level 3.
	Federal Home Loan Bank of New York Stock (Carried at Cost)
	Fair value approximates cost basis as these instruments are redeemable only with the issuing agency at face value.
	Deposits (Carried at Cost)
The fair value of non-interest-bearing demand, Crystal Checking, NOW, Super NOW, Money Market and Savings and Club accounts is the amount payable on demand at the reporting date. For fixed-maturity certificates of deposit, fair value is estimated by discounting future cash flows using the rates currently offered for deposits of similar remaining maturities.
Advances from Federal Home Loan Bank of New York (Carried at Cost)
The fair value is estimated by discounting future cash flows using rates currently offered for liabilities of similar remaining maturities, or when available, quoted market prices.
Commitments to Extend Credit
The fair value of commitments to extend credit is estimated using the 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 rates and the committed rates.
As of June 30, and March 31, 2014, the fair value of the commitments to extend credit were not considered to be material.
The carrying amounts and fair values of financial instruments are as follows:

Recent Accounting Pronouncements	'
	7. RECENT ACCOUNTING PRONOUNCEMENTS
	On January 17, 2014, The FASB issued Accounting Standards Update (“ASU”) No. 2014-04, “Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40); Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans Upon Foreclosure.” The amendments in the ASU clarify when an in substance repossession or foreclosure occurs – that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be derecognized and the real estate property recognized. The new ASU requires a creditor to reclassify a collateralized consumer mortgage loan to real estate property upon obtaining legal title to the real estate collateral, or the borrower voluntarily conveying all interest in the real estate property to the lender to satisfy the loan through a deed in lieu of foreclosure or similar legal agreement. The ASU is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. The adoption of this standard effective April 1, 2015 is not expected to have a material impact on the Company’s consolidated financial statements.
	On May 28, 2014, the FASB and IASB issued their final standard on revenue from contracts with customers. The standard, issued as ASU 2014-091 by the FASB and as IFRS 152 by the IASB, outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The goals of the revenue recognition project are to clarify and converge the revenue recognition principles under U.S. GAAP and IFRSs and to develop guidance that would streamline and enhance revenue recognition requirements while also providing “a more robust framework for addressing revenue issues.” The boards believe that the standard will improve the consistency of requirements, comparability of revenue recognition practices, and usefulness of disclosures. The ASU is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2016. The adoption of this standard effective April 1, 2017 is not expected to have a material impact on the Company’s consolidated financial statements.
