Basis of Presentation [Abstract]
Basis of Presentation	Note 1 – Basis of Presentation  The accompanying unaudited consolidated financial statements include the accounts of BCB Bancorp, Inc. (the “Company”) and the Company’s wholly owned subsidiaries, BCB Community Bank (the “Bank”), BCB Holding Company Investment Company, BCB New York Asset Management, Inc. and Pamrapo Service Corporation. The Company’s business is conducted principally through the Bank. All significant intercompany accounts and transactions have been eliminated in consolidation.  The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Regulation S-X and, therefore, do not necessarily include all information that would be included in audited consolidated financial statements. The information furnished reflects all adjustments that are, in the opinion of management, necessary for a fair presentation of consolidated financial condition and results of operations. All such adjustments are of a normal recurring nature. These results are not necessarily indicative of the results to be expected for the fiscal year ending December 31, 2018 or any other future 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 as of the date of the consolidated statement of financial condition and revenues and expenses for the periods then ended. Actual results could differ significantly from those estimates.  These unaudited consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and related notes for the year ended December 31, 2017, which are included in the Company’s Annual Report on Form 10-K as filed with the Securities and Exchange Commission. In preparing these consolidated financial statements, the Company evaluated the events and transactions that occurred between March 31, 2018, and the date these consolidated financial statements were issued.  Recent Accounting Pronouncements  In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606), which will supersede the current revenue recognition requirements in Topic 605, Revenue Recognition. The ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In August 2015, the FASB issued ASU 2015-14 which deferred the effective date of ASU 2014-09 by one year. The scope of ASC 606 excludes net interest income and other revenues associated with financial assets and liabilities, including loans, leases, securities and derivatives, which would then exclude the majority of the Company's revenues. However, the recognition and measurement of certain non-interest income items such as gain on sale of other real estate owned and deposit-related fees, could be affected by ASC 606. The Company adopted the guidance effective January 1, 2018, using the modified retrospective method. Implementation of the guidance did not have a material impact on the Company's consolidated financial statements.  In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which will supersede the current lease requirements in Topic 840. The ASU requires lessees to recognize a right of use asset and related lease liability for all leases, with a limited exception for short-term leases. Leases will be classified as either finance or operating, with the classification affecting the pattern of expense recognition in the statement of income. Currently, leases are classified as either capital or operating, with only capital leases recognized on the balance sheet. The reporting of lease related expenses in the statements of operations and cash flows will be generally consistent with the current guidance. The new guidance will be effective for the Company in 2019. Once effective, the standard will be applied using a modified retrospective transition method to the beginning of the earliest period presented. The Company is currently assessing the impacts this new standard will have on its consolidated financial statements.  In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses. ASU 2016-13 requires entities to report “expected” credit losses on financial instruments and other commitments to extend credit rather than the current “incurred loss” model. These expected credit losses for financial assets held at the reporting date are to be based on historical experience, current conditions, and reasonable and supportable forecasts. This ASU will also require enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an entity’s portfolio. These disclosures include qualitative and quantitative requirements that provide additional information about the amounts recorded in the consolidated financial statements. The amendments are effective for the Company in 2020. The Company has begun evaluating the impact the adoption of ASU 2016-13 will have on its consolidated financial statements and results of operations. The effect of this change cannot be ascertained at this point, and will depend upon factors including asset components, asset quality and market conditions at the adoption date.  In May 2017, the FASB issued ASU 2017-09, “Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting”. The amendments in this update requires that an entity account for the effects of a modification unless the fair value of the modified award is the same as the fair value of the original award immediately before the original award is modified, the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified and the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. ASU 2017-09 is effective for the Company on a prospective basis in 2018. Due to prospective application, the new guidance does not expect to have an impact on the Company’s consolidated financial statements.  ASU 2017-08, "Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities." ASU 2017-08 was issued to enhance the accounting for the amortization of premiums for purchased callable debt securities. This amendment requires that the amortization of the premium be shortened to the earliest call date. For public business entities, ASU 2017-08 is effective for fiscal years after December 15, 2018, and interim periods within those fiscal years. The adoption of ASU 2017-08 had no effect on the Company’s consolidated financial statements.  In January 2016, the FASB issued ASU 2016-01, “Financial Instruments- Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” This guidance amends existing guidance to improve accounting standards for financial instruments including clarification and simplification of accounting and disclosure requirements and the requirement for public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. These amendments are effective for public business entities for annual periods and interim periods within those annual periods beginning after December 15, 2017. The Company recorded a cumulative effect adjustment to the balance sheet as of January 1, 2018 in the amount of $126,000 , representing the unrealized gain of $175,000 at December 31, 2017 net of taxes of $49,000 . For the three months ended March 31, 2018, the Company recorded a loss to the income statement in the amount of $127,000 . In addition to the change noted above, adoption of this standard will impact the fair value disclosures included in Note 7.  In February 2018, the FASB issued ASU No. 2018-02, “Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” The ASU required a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the newly enacted federal corporate income tax rate as a result of the Tax Cuts and Jobs Act. The amount of the reclassification is the difference between the historical corporate income tax rate and the newly enacted twenty-one percent corporate income tax rate. The Company chose to early adopt the new standard for the year ending December 31, 2017, as allowed under the new standard. The amount of the reclassification for the Company was $557,000 , as shown in the Consolidated Statement of Changes in Shareholders’ Equity in the Company’s Form 10-K filing for the year ended December 31, 2017, subject to Staff Accounting Bulletin 118, Income Tax Implications of the Tax Cuts and Jobs Act (“SAB 118”). SAB 118 provides a measurement period not to extend beyond one year of the enactment date to adjust the accounting for certain elements of the tax reform. The Company does not anticipate a material adjustment to tax expense during the measurement period.

Pension and Other Postretirement Plans [Abstract]
Pension and Other Postretirement Plans	Note 3 – Pension and Other Postretirement Plans The Company assumed, through the merger with Pamrapo Bancorp, Inc., a non-contributory defined benefit pension plan covering all eligible employees of Pamrapo Savings Bank. Effective January 1, 2010, the defined benefit pension plan (“Pension Plan”), was frozen by Pamrapo Savings Bank. All benefits for eligible participants accrued in the “Pension Plan” to the freeze date have been retained. Accordingly, no employees are permitted to commence participation in the Pension Plan and future salary increases and future years of service are not considered when computing an employee’s benefits under the Pension Plan. The Pension Plan is funded in conformity with the funding requirements of applicable government regulations. The Company also acquired through the merger with Pamrapo Bancorp, Inc. a supplemental executive retirement plan (“SERP”) in which certain former employees of Pamrapo Savings Bank are covered. A SERP is an unfunded non-qualified deferred retirement plan. Participants who retire at the age of 65 (the “Normal Retirement Age”), are entitled to an annual retirement benefit equal to 75% of compensation reduced by their retirement plan annual benefits. Participants retiring before the Normal Retirement Age receive the same benefits reduced by a percentage based on years of service to the Company and the number of years prior to the Normal Retirement Age that participants retire.   Net periodic pension benefit for the three months ended March 31, 2018 and March 31, 2017 was $10,000 and $9,000 respectively. Net periodic postretirement cost for the SERP plan for the three months ended March 31, 2018 and March 31, 2017 was $3,000 and $4,000 respectively.   Note 3 – Pension and Other Postretirement Plans (Continued)  The Company, under the plan approved by its stockholders on April 28, 2011 (“2011 Stock Plan”), authorized the issuance of up to 900,000 shares of common stock of the Company pursuant to grants of stock options. Employees and directors of the Company and the Bank are eligible to participate in the 2011 Stock Plan. All stock options will be granted in the form of either "incentive" stock options or "non-qualified" stock options. Incentive stock options have certain tax advantages that must comply with the requirements of Section 422 of the Internal Revenue Code. Only employees are permitted to receive incentive stock options. On September 13, 2017, a grant of 350,000 options was declared for members of the Board of Directors and Executive Officers which vest at a rate of 10% per year and 20% per year, respectively, commencing on the first anniversary of the grant date. On September 16, 2016, a grant of 160,000 options was declared for members of the Board of Directors and the Chief Executive Officer, which vest at a rate of 10% per year and 33% per year, respectively, commencing on the first anniversary of the grant date. On December 2, 2015, a grant of 120,000 options and on March 7, 2014, a grant of 110,000 options was declared for certain members of the Board of Directors which vest at a rate of 10% per year, over ten years commencing on the first anniversary of the grant date.

Net Income per Common Share [Abstract]
Net Income per Common Share	Note 4 – Net Income per Common Share  Basic net income per common share is computed by dividing net income less dividends on preferred stock by the weighted average number of shares of common stock outstanding. The diluted net income per common share is computed by adjusting the weighted average number of shares of common stock outstanding to include the effects of outstanding stock options, if dilutive, using the treasury stock method. Dilution is not applicable in periods of net loss. For the three months ended March 31, 2018 and 2017, the difference in the weighted average number of basic and diluted common shares was due solely to the effects of outstanding stock options. No adjustments to net income were necessary in calculating basic and diluted net income per share. For the three months ended March 31, 2018 and 2017 the weighted average number of outstanding options considered to be anti-dilutive were 1,388 and 8,757 respectively.   The following is a reconciliation of the numerators and denominators of the basic and diluted earnings per share computations:      For the Three Months Ended March 31,  2018 2017  Income Shares Per Share Income Shares Per Share  (Numerator) (Denominator) Amount (Numerator) (Denominator) Amount  (In Thousands, Except per share data)   Net income available to common stockholders $ 4,466 $ 2,795   Basic earnings per share-  Income available to  Common stockholders $ 4,466 15,048 $ 0.30 $ 2,795 11,278 $ 0.25    Effect of dilutive securities:  Stock options - 133 - 82   Diluted earnings per share-  Income available to  Common stockholders $ 4,466 15,181 $ 0.29 $ 2,795 11,360 $ 0.25

Consideration is given to (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) whether the Company intends to sell the security or more likely than not will be required to sell the security before its anticipated recovery. At March 31, 2018 and December 31, 2017, management performed an assessment for possible OTTI of the Company’s residential mortgage-backed securities on an issue-by-issue basis, relying on information obtained from various sources, including publicly available financial data, ratings by external agencies, brokers and other sources. The extent of individual analysis applied to each security depended on the size of the Company’s investment, as well as management’s perception of the credit risk associated with each security. Based on the results of the assessment, management believes impairment of these securities, at March 31, 2018 and December 31, 2017, to be temporary.

(2) Includes home equity lines of credit.     Note 6 - Loans Receivable and Allowance for Loan Losses (Continued) Allowance for Loan Losses  The allowance for loan loss is evaluated regularly by management and reflects consideration of all significant factors that affect the collectability of the loan portolio. The Company’s methodology for assessing the adequacy of the allowance for loan losses consists of several key elements. These elements include a general allocated reserve for performing loans, a specific reserve for impaired loans and an unallocated portion.  The Company consistently applies the following comprehensive methodology. During the quarterly review of the allowance for loan losses, the Company considers a variety of qualitative factors that include:  " Lending Policies and Procedures " Personnel responsible for the particular portfolio - relative to experience and ability of staff " Trend for past due, criticized and classified loans " Relevant economic factors " Quality of the loan review system " Value of collateral for collateral dependent loans " The effect of any concentrations of credit and the changes in the level of such concentrations " Other external factors The methodology includes the segregation of the loan portfolio into two divisions. Loans that are performing and loans that are impaired. Loans which are performing are evaluated homogeneously by loan class or loan type. The allowance for performing loans is evaluated based on historical loan experience with an adjustment for qualitative factors referred to above. Impaired loans are loans which are more than 90 days delinquent, troubled debt restructured, or adversely classified. These loans are individually evaluated for loan loss either by current appraisal, or net present value. Management reviews the overall estimate for feasibility and bases the loan loss provision accordingly.  The loan portfolio is segmented into the following loan classes, where the risk level for each class is analyzed when determining the allowance for loan losses:  Residential single family real estate loans involve certain risks such as interest rate risk and risk of non-repayment. Adjustable-rate residential family real estate loans decreases the interest rate risk to the Bank that is associated with changes in interest rates but involve other risks, primarily because as interest rates rise, the payment by the borrower rises to the extent permitted by the terms of the loan, thereby increasing the potential for default. At the same time, the marketability of the underlying property may be adversely affected by higher interest rates. Repayment risk may be affected by a number of factors including, but not necessarily limited to, job loss, divorce, illness and personal bankruptcy of the borrower.  Construction lending is generally considered to involve a high risk due to the concentration of principal in a limited number of loans and borrowers and the effects of the general economic conditions on developers and builders. Moreover, a construction loan can involve additional risks because of the inherent difficulty in estimating both a property’s value at completion of the project and the estimated cost (including interest) of the project. The nature of these loans is such that they are generally difficult to evaluate and monitor. In addition, speculative construction loans to a builder are not necessarily pre-sold and thus pose a greater potential risk to the Bank than construction loans to individuals on their personal residence.  Commercial and multi-family real estate lending entails significant additional risks as compared with residential family property lending. Such loans typically involve large loan balances to single borrowers or groups of related borrowers. The payment experience on such loans is typically dependent on the successful operation of the real estate project. The success of such projects is sensitive to changes in supply and demand conditions in the market for commercial real estate as well as economic conditions generally.  Commercial business lending, including lines of credit, is generally considered higher risk due to the concentration of principal in a limited number of loans and borrowers and the effects of general economic conditions on the business. Commercial business loans are primarily secured by inventories and other business assets. In most cases, any repossessed collateral for a defaulted commercial business loans will not provide an adequate source of repayment of the outstanding loan balance.  Home equity lending entails certain risks such as interest rate risk and risk of non-repayment. The marketability of the underlying property may be adversely affected by higher interest rates, decreasing the collateral securing the loan. Repayment risk can be affected by job loss, divorce, illness and personal bankruptcy of the borrower. Home equity line of credit lending entails securing an equity interest in the borrower’s home. In many cases, the Bank’s position in these loans is as a junior lien holder to another institution’s superior lien. This type of lending is often priced on an adjustable rate basis with the rate set at or above a predefined index. Adjustable-rate loans decrease the interest rate risk to the Bank that is associated with changes in interest rates but involve other risks, primarily because as interest rates rise, the payment by the borrower rises to the extent permitted by the terms of the loan, thereby increasing the potential for default.  Other consumer loans generally have more credit risk because of the type and nature of the collateral and, in certain cases, the absence of collateral. Consumer loans generally have shorter terms and higher interest rates than other lending. In addition, consumer lending collections are dependent on the borrower’s continuing financial stability, and thus are more likely to be adversely effected by job loss, divorce, illness and personal bankruptcy. In most cases, any repossessed collateral for a defaulted consumer loan will not provide an adequate source of repayment of the outstanding loan.  The Company also maintains an unallocated allowance. The unallocated allowance is used to cover any factors or conditions which may cause a potential loan loss but are not specifically identifiable. It is prudent to maintain an unallocated portion of the allowance because no matter how detailed an analysis of potential loan losses is performed, these estimates lack some element of precision. Management must make estimates using assumptions and information that is often subjective and changing rapidly.             Note 6 - Loans Receivable and Allowance for Loan Losses (Continued)  Criticized and Classified Assets .  Our policies provide for a classification system for problem assets. Under this classification system, problem assets are classified as “substandard,” “doubtful,” or “loss.”  When we classify problem assets, we may establish general allowances for loan losses in an amount deemed prudent by management. General allowances represent loss allowances which have been established to recognize the inherent risk associated with lending activities, but which, unlike specific allowances, have not been allocated to particular problem assets. A portion of general loss allowances established to cover possible losses related to assets classified as substandard or doubtful may be included in determining our regulatory capital. Specific valuation allowances for loan losses generally do not qualify as regulatory capital. As of March 31, 2018, we had $42,000 in assets classified as losses, of which $42,000 were classified as impaired, and $20.3 million in assets classified as substandard, of which $20.3 million were classified as impaired. The loans classified as substandard represent primarily commercial loans secured either by residential real estate, commercial real estate or heavy equipment. The loans that have been classified substandard were classified as such primarily due to payment status, because updated financial information has not been timely provided, or the collateral underlying the loan is in the process of being revalued.  The Company’s internal credit risk grades are based on the definitions currently utilized by the banking regulatory agencies. The grades assigned and definitions are as follows, and loans graded excellent, above average, good and watch list (risk ratings 1-5) are treated as “pass” for grading purposes. The “criticized” risk rating (6) and the “classified” risk ratings (7-9) are detailed below:  6 – Special Mention- Loans currently performing but with potential weaknesses including adverse trends in borrower’s operations, credit quality, financial strength, or possible collateral deficiency.  7 – Substandard - Loans that are inadequately protected by current sound worth, paying capacity, and collateral support. Loans on “nonaccrual” status. The loan needs special and corrective attention.  8 – Doubtful - Weaknesses in credit quality and collateral support make full collection improbable, but pending reasonable factors remain sufficient to defer the loss status.  9 – Loss - Continuance as a bankable asset is not warranted. However, this does not preclude future attempts at partial recovery.

Note 6 - Loans Receivable and Allowance for Loan Losses (Continued) A troubled debt restructured (“TDR”) is a loan that has been modified whereby the Company has agreed to make certain concessions to a borrower to meet the needs of both the borrower and the Company to maximize the ultimate recovery of a loan. A TDR occurs when a borrower is experiencing, or is expected to experience, financial difficulties and the loan is modified using a modification that would otherwise not be granted to the borrower. The types of concessions granted generally include, but are not limited to interest rate reductions, limitations on the accrued interest charged, term extensions, and deferment of principal.  The following table presents the total TDR loans at March 31, 2018, excluding the purchase impairment mark on the acquired loans with deteriorated credit.

Fair Values of Financial Instru

Fair Values of Financial Instruments	3 Months Ended

Fair Values of Financial Instruments [Abstract]
Fair Values of Financial Instruments	Note 7 – Fair Values of Financial Instruments  Guidance on fair value measurements establishes a fair value hierarchy that prioritizes the inputs to valuation methods used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows: Level 1 : Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2 : Quoted prices in markets that are not active, or inputs that are observable either directly or indirectly, for substantially the full term of the asset or liability. Level 3 : Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e. supported with little or no market activity). An asset 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.  The only assets or liabilities that the Company measured at fair value on a recurring basis were as follows. (In Thousands):   (Level 1) (Level 2)  Quoted Prices in Significant (Level 3)  Active Markets Other Significant  for Identical Observable Unobservable  Description Total Assets Inputs Inputs  As of March 31, 2018:  Securities  Residential mortgage backed securities $ 119,158 $ - $ 119,158 $ -  Preferred stock 8,166 8,166 - -  Total Securities 127,324 8,166 119,158 -   As of December 31, 2017:  Securities  Residential mortgage backed securities $ 111,793 $ - $ 111,793 $ -  Municipal obligations 2,502 - 2,502 -  Preferred stock 8,294 8,294 - -  Total Securities 122,589 8,294 114,295 -    The Company’s policy is to recognize transfers between levels as of the actual date of the event or change in circumstances that caused the transfer. There were no transfers of assets or liabilities into or out of Level 1, Level 2, or Level 3 of the fair value hierarchy during the three months ended March 31, 2018 and 2017. The only assets or liabilities that the Company measured at fair value on a nonrecurring basis were as follows.

(Dollars in thousands):      Quantitative Information about Level 3 Fair Value Measurements  Fair Value Valuation Unobservable Range  Estimate Techniques Input  March 31, 2018:  Impaired Loans $ 10,183 Appraisal of collateral (1) Appraisal adjustments (2) 0% -10%    Other real estate owned $ 1,412 Appraisal of collateral (1) Appraisal adjustments (2) 0% -10%           Fair Value Valuation Unobservable Range  Estimate Techniques Input  December 31, 2017:  Impaired Loans $ 10,369 Appraisal of collateral (1) Appraisal adjustments (2) 0% -10%    Other real estate owned $ 532 Appraisal of collateral (1) Appraisal adjustments (2) 0% -10%   (1) Fair value is generally determined through independent appraisals of the underlying collateral, which generally include various level 3 inputs which are not objectively determinable. (2) Appraisals may be adjusted by management for qualitative factors such as economic conditions and estimated liquidation expenses. The range of liquidation expenses and other appraisal adjustments are presented as a percent of the appraisal . The following information should not be interpreted as an estimate of the fair value of the entire Company since a fair value calculation is only provided for a limited portion of the Company’s assets and liabilities. Due to a wide range of valuation techniques and the degree of subjectivity used in making the estimates, comparisons between the Company’s disclosures and those of other companies may not be meaningful. The following methods and assumptions were used to estimate the fair values of the Company’s financial instruments as of March 31, 2018 and December 31, 2017.   Cash and Cash Equivalents and Interest-Earning Time Deposits (Carried at Cost) The carrying amounts reported in the consolidated statements of financial condition for cash and short-term instruments approximate fair values. Securities The fair value of securities available for sale (carried at fair value) are determined by matrix pricing (Level 2), which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted market prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted prices. Loans Held for Sale (Carried at Lower of Cost or Fair Value) The fair value of loans held for sale is determined, when possible, using quoted secondary-market prices. If no such quoted prices exist, the fair value of a loan is determined using quoted prices for a similar loan or loans, adjusted for specific attributes of that loan. Loans held for sale are carried at their cost as of March 31, 2018 and December 31, 2017. Loans Receivable (Carried at Cost) The fair value of loans are estimated using discounted cash flow analyses, using market rates at the balance sheet date that reflect the credit and interest rate-risk inherent in the loans. Projected future cash flows are calculated based upon contractual maturity or call dates, projected repayments and prepayments of principal. Generally, for variable rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values.     Note 7 – Fair Values of Financial Instruments (Continued) Impaired Loans (Generally Carried at Fair Value) A loan is impaired when, based on current information and events, it is probable that a creditor will be unable to collect all amounts due according to the contractual terms of the loan agreement. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, or as a practical expedient, at the loans observable market price or the fair value of the collateral if the loan is collateral dependent. Fair value is generally determined based upon independent third-party appraisals of the properties, or discounted cash flows based upon the expected proceeds. These assets are included as Level 3 fair values, based upon the lowest level of input that is significant to the fair value measurements. The fair value at March 31, 2018 and December 31, 2017 consisted of the loan balances of $ 12.0 million and $12.402 million, net of a valuation allowance of $1.8 million and $2.033 million, respectively.   Real Estate Owned (Generally Carried at Fair Value) Real Estate Owned is generally carried at fair value which is determined based upon independent third-party appraisals of the properties, or based upon the expected proceeds from a pending sale. These assets are included as Level 3 fair values, based upon the lowest level of input that is significant to the fair value measurements. FHLB of New York Stock (Carried at Cost) The carrying amount of restricted investment in bank stock approximates fair value, and considers the limited marketability of such securities. Interest Receivable and Payable (Carried at Cost) The carrying amount of interest receivable and interest payable approximates its fair value. Deposits (Carried at Cost) The fair values disclosed for demand deposits (e.g., interest and non-interest checking, passbook savings and money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered in the market on certificates to a schedule of aggregated expected monthly maturities on time deposits. Long-Term Debt (Carried at Cost) Fair values of long-term debt are estimated using discounted cash flow analysis, based on quoted prices for new long-term debt with similar credit risk characteristics, terms and remaining maturity. These prices obtained from this active market represent a market value that is deemed to represent the transfer price if the liability were assumed by a third party.
