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 June 30, 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 require 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. The Company adopted ASU 2017-09 on a prospective basis in January 2018. Due to prospective application, the impact on the Company’s consolidated financial statements will be dependent upon the terms of future modifications. In March, 2017, the FASB issued 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. The Company adopted ASU 2017-08 as of January 1, 2018 with 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 six months ended June 30, 2018, the Company recorded a loss to the income statement in the amount of $160,000. In addition to the change noted above, adoption of this standard will impact the fair value disclosures included in Note 10. 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.
