Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1. Summary of Significant Accounting Policies Basis of Presentation The Consolidated Financial Statements include the accounts of Eagle Bancorp, Inc. and its subsidiaries (the “Company”). Active subsidiaries include: EagleBank (the “Bank”), Eagle Insurance Services, LLC, Bethesda Leasing, LLC, and Landroval Municipal Finance, Inc., with all significant intercompany transactions eliminated. The Consolidated Financial Statements of the Company included herein are unaudited. The Consolidated Financial Statements reflect all adjustments, consisting of normal recurring accruals that in the opinion of management, are necessary to present fairly the results for the periods presented. The amounts as of and for the year ended December 31, 2018 were derived from audited Consolidated Financial Statements. Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission. The Company applies the accounting policies contained in Note 1 to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. There have been no significant changes to the Company’s Accounting Policies as disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 except as indicated in the “Accounting Standards Adopted in 2019” section below. The Company believes that the disclosures are adequate to make the information presented not misleading. Certain reclassifications have been made to amounts previously reported to conform to the current period presentation. These statements should be read in conjunction with the audited Consolidated Financial Statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. Operating results for the three and six months ended June 30, 2019 are not necessarily indicative of the results of operations to be expected for the remainder of the year, or for any other period. Nature of Operations The Company, through the Bank, conducts a full service community banking business, primarily in Northern Virginia, Suburban Maryland, and Washington, D.C. The primary financial services offered by the Bank include real estate, commercial and consumer lending, as well as traditional deposit and repurchase agreement products. The Bank is also active in the origination and sale of residential mortgage loans, the origination of small business loans, and the origination, securitization and sale of multifamily Federal Housing Administration (“FHA”) loans. The guaranteed portion of small business loans, guaranteed by the Small Business Administration (“SBA”), is typically sold to third party investors in a transaction apart from the loan’s origination. The Bank offers its products and services through twenty banking offices, five lending centers and various electronic capabilities, including remote deposit services and mobile banking services. Eagle Insurance Services, LLC, a subsidiary of the Bank, offers access to insurance products and services through a referral program with a third party insurance broker. Landroval Municipal Finance, Inc., a subsidiary of the Bank, focuses on lending to municipalities by buying debt on the public market as well as direct purchase issuance. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results may differ from those estimates and such differences could be material to the financial statements. New Authoritative Accounting Guidance Accounting Standards Adopted in 2019 ASU 2016-02, “Leases (Topic 842).” ASU 2016-02 has, among other things, required lessees to recognize a lease liability, which is a lessee’s obligation to make lease payments, measured on a discounted basis; and a right-of-use (“ROU”) asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. ASU 2016-02 did not significantly change lease accounting requirements applicable to lessors; however, certain changes were made to align, where necessary, lessor accounting with the lessee accounting model and ASC Topic 606, “Revenue from Contracts with Customers.” ASU 2016-02 became effective for us on January 1, 2019 and initially required transition using a modified retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. In July 2018, the FASB issued ASU 2018-11, “Leases (Topic 842) – Targeted Improvements,” which, among other things, provides an additional transition method that allows entities to not apply the guidance in ASU 2016-02 in the comparative periods presented in the financial statements and instead recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. In December 2018, the FASB also issued ASU 2018-20, “Leases (Topic 842) - Narrow-Scope Improvements for Lessors,” which provides for certain policy elections and changes lessor accounting for sales and similar taxes and certain lessor costs. Upon adoption of ASU 2016-02, ASU 2018-11 and ASU 2018-20 on January 1, 2019, we recognized ROU assets of $29.6 million and related lease liabilities of $33.5 million which reduced the March 31, 2019 total risk based capital ratio by six basis points. We elected to apply certain practical expedients provided under ASU 2016-02 whereby we did not reassess (i) whether any expired or existing contracts were or contained leases, (ii) the lease classification for any expired or existing leases and (iii) initial direct costs for any existing leases. We also elected to not apply the recognition requirements of ASU 2016-02 to any short-term leases (as defined by related accounting guidance). We utilized the modified-retrospective transition approach prescribed by ASU 2018-11. Accounting Standards Pending Adoption A SU 2016-13, “Measurement of Credit Losses on Financial Instruments (Topic 326).” This ASU significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. In issuing the standard, the FASB is responding to criticism that today’s guidance for determining the allowance for credit losses delays recognition of expected future credit losses. The standard will replace today’s “incurred loss” approach with an “expected loss” model. The new model, referred to as the current expected credit loss (“CECL”) model, will apply to: (1) financial assets subject to credit losses and measured at amortized cost, and (2) certain off-balance sheet credit exposures. This includes, but is not limited to, loans, leases, held-to-maturity securities, loan commitments, and financial guarantees. The CECL model does not apply to available-for-sale (“AFS”) debt securities. For AFS debt securities with unrealized losses, entities will measure credit losses in a manner similar to what they do today, except that the losses will be recognized as allowances rather than reductions in the amortized cost of the securities. The ASU also simplifies the accounting model for purchased credit-impaired debt securities and loans. ASU 2016-13 also expands the disclosure requirements regarding an entity’s assumptions, models, and methods for estimating the allowance for loan and lease losses. In addition, entities will need to disclose the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination. ASU No. 2016-13 is effective for the Company beginning on January 1, 2020. Entities will apply any changes resulting from the application of the new standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (i.e., modified retrospective approach). We have substantially concluded our data gap analysis and have contracted with third parties to develop and evaluate a model to comply with CECL requirements. We have entered our data into the model and are working on the qualitative and forecasting aspects of the methodology. We have established a steering committee with representation from various departments across the enterprise. The committee has agreed to a project plan and has regular meetings to ensure adherence to our implementation timeline. The Company is currently evaluating the provisions of ASU No. 2016-13 to determine the potential impact the new standard will have on the Company's Consolidated Financial Statements.
