Accounting Policies [Abstract]
BASIS OF PRESENTATION	Bridge Bancorp, Inc. (the “Company”) is a bank holding company incorporated under the laws of the State of New York. The Company’s business currently consists of the operations of its wholly-owned subsidiary, The Bridgehampton National Bank (the “Bank”). The Bank’s operations include its real estate investment trust subsidiary, Bridgehampton Community, Inc.; a financial title insurance subsidiary, Bridge Abstract LLC (“Bridge Abstract”); and an investment services subsidiary, Bridge Financial Services, Inc. (“Bridge Financial Services”). In addition to the Bank, the Company has another subsidiary, Bridge Statutory Capital Trust II (“the Trust”), which was formed in 2009 and sold $16.0 million of 8.5% cumulative convertible trust preferred securities (“TPS”) in a private placement to accredited investors. In accordance with accounting guidance, the Trust is not consolidated in the Company’s financial statements. The TPS were redeemed effective January 18, 2017. The accompanying Unaudited Consolidated Financial Statements, which include the accounts of the Company and its wholly-owned subsidiary, the Bank, have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. The Unaudited Consolidated Financial Statements included herein reflect all normal recurring adjustments that are, in the opinion of management, necessary for a fair presentation of the results for the interim periods presented. In preparing the interim financial statements, management has made estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the reported periods. Such estimates are subject to change in the future as additional information becomes available or previously existing circumstances are modified. Actual future results could differ significantly from those estimates. The annualized results of operations for the three months ended March 31, 2017 are not necessarily indicative of the results of operations that may be expected for the entire fiscal year. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain reclassifications have been made to prior year amounts, and the related discussion and analysis, to conform to the current year presentation. These reclassifications did not have an impact on net income or total stockholders’ equity. The Unaudited Consolidated Financial Statements should be read in conjunction with the Audited Consolidated Financial Statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016.
RECENT ACCOUNTING PRONOUNCEMENTS	In March 2017, the FASB issued ASU No. 2017-08, “Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20) - Premium Amortization on Purchased Callable Debt Securities.” ASU 2017-08 shortens the amortization period for certain callable debt securities held at a premium to the earliest call date rather than to maturity to more closely align the amortization period to expectations incorporated in market pricing on the underlying securities. There is no change to callable securities held at a discount which continue to be amortized to maturity. For public business entities, like the Company, ASU 2017-08 is effective for interim and annual reporting periods beginning after December 15, 2018. ASU is not expected to have a material impact on the Company’s consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-07, “Compensation - Retirement Benefits (Topic 715) - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” ASU 2017-07 changes the reporting for the service cost component of net benefit cost from the reporting for the other components of net benefit cost. The service cost component must be reported in the same line item as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. The line item used in the income statement to present the other components of net benefit cost must be disclosed. Additionally, only the service cost component of net benefit cost is eligible for capitalization, if applicable. For public business entities, like the Company, ASU 2017-07 is effective for interim and annual periods beginning after December 15, 2017. Since the provisions of ASU 2017-07 which are applicable to the Company are disclosure related, adoption will not have a financial impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, “Intangibles – Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment.” ASU 2017-04 simplifies the test for goodwill impairment by eliminating Step 2 from the goodwill impairment test. An entity should perform its annual or interim goodwill impairment test by comparing the fair value of the reporting unit to its carrying amount and recognize an impairment charge for the amount by which the carrying amount of the reporting unit exceeds its fair value, not to exceed the total amount of goodwill allocated to that reporting unit. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. A public business entity that is an SEC filer, like the Company, should adopt ASU 2017-04 for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. ASU 2017-04 is not expected to have a material impact on the Company’s consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 significantly changes the impairment model for most financial assets that are measured at amortized cost and certain other instruments from an incurred loss model to an expected loss model and also provides for recording credit losses on available for sale debt securities through an allowance account. ASU 2016-13 also requires certain incremental disclosures. ASU 2016-13 is effective for public entities that are SEC filers, like the Company, for interim and annual reporting periods beginning after December 15, 2019. The Company is currently assessing its data and system needs and evaluating the impact of adopting ASU 2016-13, but can not yet determine the overall impact this guidance will have on the Company’s consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” ASU 2016-02 affects any entity that enters into a lease and is intended to increase the transparency and comparability of financial statements among organizations. ASU 2016-02 requires, among other changes, a lessee to recognize on its balance sheet a lease asset and a lease liability for those leases previously classified as operating leases. The lease asset would represent the right to use the underlying asset for the lease term and the lease liability would represent the discounted value of the required lease payments to the lessor. ASU 2016-02 would also require entities to disclose key information about leasing arrangements. ASU 2016-02 is effective for interim and annual reporting periods beginning after December 15, 2018. Currently the Bank leases thirty seven properties as branch locations and one property as a loan production office. The adoption of ASU 2016-02 will result in an increase in the Company’s assets and liabilities. The Company is in the process of quantifying the impact ASU 2016-02 will have on the Company’s consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606).” The amendments in ASU 2014-09 are intended to improve financial reporting by providing a comprehensive framework for addressing revenue recognition issues that can be applied to all contracts with customers regardless of industry-specific or transaction-specific fact patterns. While the guidance in ASU 2014-09 supersedes most existing industry-specific revenue recognition accounting guidance, much of a bank’s revenue comes from financial instruments such as debt securities and loans which are scoped-out of the guidance. The amendments also include improved disclosures to enable users of financial statements to better understand the nature, amount, timing and uncertainty of revenue that is recognized. For public entities, like the Company, ASU 2014-09, as amended, is effective for interim and annual reporting periods beginning after December 15, 2017. Most of the Company’s revenue comes from financial instruments, i.e. loans and securities, which are not within the scope of ASU 2014-09. The Company is in the process of evaluating the impact ASU 2014-09 will have on non-interest income but does not expect the adoption of the guidance to have a material impact on the Company’s consolidated financial statements.
