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”), EagleBank (the “Bank”), Eagle Commercial Ventures, LLC (“ECV”), Eagle Insurance Services, LLC, and Bethesda Leasing, LLC, 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, 2017 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. 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, 2017. 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, 2017. Operating results for the three months ended March 31, 2018 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 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. Eagle Commercial Ventures, LLC, a direct subsidiary of the Company, has provided subordinated financing for the acquisition, development and construction of real estate projects; these transactions involve higher levels of risk, together with commensurate higher returns. 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 2018 ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” The majority of our revenue-generating transactions are not subject to ASC 606, including revenue generated from financial instruments, such as our loans, letters of credit, derivatives and investment securities, as well as revenue related to our mortgage servicing activities, as these activities are subject to other GAAP discussed elsewhere within our disclosures. Substantially all of the Company’s revenue is generated from contracts with customers. Descriptions of our revenue-generating activities that are within the scope of ASC 606, which are presented in our income statements as components of noninterest income are as follows: ● Service charges on deposit accounts - these represent general service fees for monthly account maintenance and activity- or transaction-based fees and consist of transaction-based revenue, time-based revenue (service period), item-based revenue or some other individual attribute-based revenue. Revenue is recognized when our performance obligation is completed which is generally monthly for account maintenance services or when a transaction has been completed (such as a wire transfer). Payment for such performance obligations are generally received at the time the performance obligations are satisfied. ● Other Fees – generally, the Company receives compensation when a customer that it refers opens an account with certain third-parties. This category includes credit card, investment advisory, and interchange fees. The timing and amount of revenue recognition is not materially impacted by the new standard. ● Sale of OREO – ASU 2014-09 prescribes derecognition requirements for the sale of OREO that are less prescriptive than existing derecognition requirements. Previously, the Company was required to assess 1) the adequacy of a buyer’s initial and continuing investments and 2) the seller’s continuing involvement with the property. ASU 2014-09 requires an entity to assess whether it is “probable” that it will collect the consideration to which it will be entitled in exchange for transferring the asset to the customer. The new requirements could result in earlier revenue recognition; however, such sales are infrequent and the impact of this change is not expected to be material to our financial statements. A contract asset balance occurs when an entity performs a service for a customer before the customer pays consideration (resulting in a contract receivable) or before payment is due (resulting in a contract asset). A contract liability balance is an entity’s obligation to transfer a service to a customer for which the entity has already received payment (or payment is due) from the customer. The Company’s noninterest revenue streams are largely based on transactional activity, or standard month-end revenue accruals based on fee schedules. Consideration is often received immediately or shortly after the Company satisfies its performance obligation and revenue is recognized. The Company does not typically enter into long-term revenue contracts with customers, and therefore, does not have contract balances material to our financial statements. As of March 31, 2018 and December 31, 2017, the Company did not have any significant contract balances. In connection with the adoption of Topic 606, an entity is required to capitalize, and subsequently amortize into expense, certain incremental costs of obtaining a contract with a customer if these costs are expected to be recovered. The incremental costs of obtaining a contract are those costs that an entity incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained (for example, sales commission). The Company utilizes the practical expedient which allows entities to immediately expense contract acquisition costs when the asset that would have resulted from capitalizing these costs would have been amortized in one year or less. Upon adoption of Topic 606, the Company did not capitalize any contract acquisition cost.

Cash and Cash Equivalents [Abstract]
Cash and Due from Banks	Note 2. Cash and Due from Banks Regulation D of the Federal Reserve Act requires that banks maintain noninterest reserve balances with the Federal Reserve Bank based principally on the type and amount of their deposits. During 2018, the Bank maintained balances at the Federal Reserve sufficient to meet reserve requirements, as well as significant excess reserves, on which interest is paid. Additionally, the Bank maintains interest bearing balances with the Federal Home Loan Bank of Atlanta and noninterest bearing balances with domestic correspondent banks as compensation for services they provide to the Bank.

Gross unrealized losses and fair value by length of time that the individual available-for-sale securities have been in a continuous unrealized loss position are as follows: Less than 12 Months 12 Months or Greater Total Estimated Estimated Estimated March 31, 2018 Number of Fair Unrealized Fair Unrealized Fair Unrealized (dollars in thousands) Securities Value Losses Value Losses Value Losses U.

The weighted average duration of debt securities, which comprise 99.9% of total investment securities, is relatively short at 3.8 years. If quoted prices are not available, fair value is measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss assumptions. The Company does not believe that the investment securities that were in an unrealized loss position as of March 31, 2018 represent an other-than-temporary impairment. The Company does not intend to sell the investments and it is more likely than not that the Company will not have to sell the securities before recovery of its amortized cost basis, which may be at maturity. The amortized cost and estimated fair value of investments available-for-sale at March 31, 2018 and December 31, 2017 by contractual maturity are shown in the table below. Expected maturities for residential mortgage backed securities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

For the year ended December 31, 2017, gross realized gains on sales of investment securities were $796 thousand and gross realized losses on sales of investment securities were $254 thousand. Proceeds from sales and calls of investment securities for the three months ended March 31, 2018 were $17.3 million compared to $51.2 million for the same period in 2017. The carrying value of securities pledged as collateral for certain government deposits, securities sold under agreements to repurchase, and certain lines of credit with correspondent banks at March 31, 2018 and December 31, 2017 was $454.8 million and $465.4 million, respectively, which is well in excess of required amounts in order to operationally provide significant reserve amounts for new business. As of March 31, 2018 and December 31, 2017, there were no holdings of securities of any one issuer, other than the U.S. Government and U.S. agency securities, which exceeded ten percent of shareholders’ equity.

Mortgage Banking Derivative As part of its mortgage banking activities, the Bank enters into interest rate lock commitments, which are commitments to originate loans where the interest rate on the loan is determined prior to funding and the customers have locked into that interest rate. The Bank then locks in the loan and interest rate with an investor and commits to deliver the loan if settlement occurs (“best efforts”) or commits to deliver the locked loan in a binding (“mandatory”) delivery program with an investor. Certain loans under interest rate lock commitments are covered under forward sales contracts of mortgage backed securities (“MBS”). Forward sales contracts of MBS are recorded at fair value with changes in fair value recorded in noninterest income. Interest rate lock commitments and commitments to deliver loans to investors are considered derivatives. The market value of interest rate lock commitments and best efforts contracts are not readily ascertainable with precision because they are not actively traded in stand-alone markets. The Bank determines the fair value of interest rate lock commitments and delivery contracts by measuring the fair value of the underlying asset, which is impacted by current interest rates, taking into consideration the probability that the interest rate lock commitments will close or will be funded. Certain additional risks arise from these forward delivery contracts in that the counterparties to the contracts may not be able to meet the terms of the contracts. The Bank does not expect any counterparty to any MBS to fail to meet its obligation. Additional risks inherent in mandatory delivery programs include the risk that, if the Bank does not close the loans subject to interest rate risk lock commitments, it will still be obligated to deliver MBS to the counterparty under the forward sales agreement. Should this be required, the Bank could incur significant costs in acquiring replacement loans or MBS and such costs could have an adverse effect on mortgage banking operations. The fair value of the mortgage banking derivatives is recorded as a freestanding asset or liability with the change in value being recognized in current earnings during the period of change. At March 31, 2018 the Bank had mortgage banking derivative financial instruments with a notional value of $55.3 million related to its forward contracts as compared to $37.1 million at December 31, 2017. The fair value of these mortgage banking derivative instruments at March 31, 2018 was $51 thousand included in other assets and $84 thousand included in other liabilities as compared to $43 thousand included in other assets and $10 thousand included in other liabilities at December 31, 2017. Included in other noninterest income for the three months ended March 31, 2018 was a net loss of $87 thousand, relating to mortgage banking derivative instruments as compared to a net gain of $290 thousand as of March 31, 2017. The amount included in other noninterest income for the three months ended March 31, 2018 pertaining to its mortgage banking hedging activities was a net realized gain of $91 thousand as compared to a net realized loss of $845 thousand as of March 31, 2017.

Loans and Allowance for Credit Losses	Note 5. Loans and Allowance for Credit Losses The Bank makes loans to customers primarily in the Washington, D.C. metropolitan area and surrounding communities. A substantial portion of the Bank’s loan portfolio consists of loans to businesses secured by real estate and other business assets. Loans, net of unamortized net deferred fees, at March 31, 2018 and December 31, 2017 are summarized by type as follows: March 31, 2018 December 31, 2017 (dollars in thousands) Amount % Amount % Commercial $ 1,426,042 22 % $ 1,375,939 21 % Income producing - commercial real estate 3,137,498 47 % 3,047,094 48 % Owner occupied - commercial real estate 800,747 12 % 755,444 12 % Real estate mortgage - residential 103,932 2 % 104,357 2 % Construction - commercial and residential 1,000,266 15 % 973,141 15 % Construction - C&I (owner occupied) 40,547 1 % 58,691 1 % Home equity 90,271 1 % 93,264 1 % Other consumer 3,223 — 3,598 — Total loans 6,602,526 100 % 6,411,528 100 % Less: allowance for credit losses (65,807 ) (64,758 ) Net loans $ 6,536,719 $ 6,346,770 Unamortized net deferred fees amounted to $24.3 million and $23.9 million at March 31, 2018 and December 31, 2017, respectively. As of March 31, 2018 and December 31, 2017, the Bank serviced $208.7 million and $195.3 million, respectively, of multifamily FHA loans, SBA loans and other loan participations which are not reflected as loan balances on the Consolidated Balance Sheets. Loan Origination / Risk Management The Company’s goal is to mitigate risks in the event of unforeseen threats to the loan portfolio as a result of economic downturn or other negative influences. Plans for mitigating inherent risks in managing loan assets include: carefully enforcing loan policies and procedures, evaluating each borrower’s business plan during the underwriting process and throughout the loan term, identifying and monitoring primary and alternative sources for loan repayment, and obtaining collateral to mitigate economic loss in the event of liquidation. Specific loan reserves are established based upon credit and/or collateral risks on an individual loan basis. A risk rating system is employed to proactively estimate loss exposure and provide a measuring system for setting general and specific reserve allocations. The composition of the Company’s loan portfolio is heavily weighted toward commercial real estate, both owner occupied and income producing real estate. At March 31, 2018, owner occupied - commercial real estate and construction - C&I (owner occupied) represent approximately 13% of the loan portfolio. At March 31, 2018, non-owner occupied commercial real estate and real estate construction represented approximately 62% of the loan portfolio. The combined owner occupied and commercial real estate loans represent approximately 75% of the loan portfolio. These loans are underwritten to mitigate lending risks typical of this type of loan such as declines in real estate values, changes in borrower cash flow and general economic conditions. The Bank typically requires a maximum loan to value of 80% and minimum cash flow debt service coverage of 1.15 to 1.0. Personal guarantees may be required, but may be limited. In making real estate commercial mortgage loans, the Bank generally requires that interest rates adjust not less frequently than five years. The Company is also an active traditional commercial lender providing loans for a variety of purposes, including working capital, equipment and account receivable financing. This loan category represents approximately 22% of the loan portfolio at March 31, 2018 and was generally variable or adjustable rate. Commercial loans meet reasonable underwriting standards, including appropriate collateral and cash flow necessary to support debt service. Personal guarantees are generally required, but may be limited. SBA loans represent approximately 2% of the commercial loan category of loans. In originating SBA loans, the Company assumes the risk of non-payment on the unguaranteed portion of the credit. The Company generally sells the guaranteed portion of the loan generating noninterest income from the gains on sale, as well as servicing income on the portion participated. SBA loans are subject to the same cash flow analyses as other commercial loans. SBA loans are subject to a maximum loan size established by the SBA as well as internal loan size guidelines. Approximately 1% of the loan portfolio at March 31, 2018 consists of home equity loans and lines of credit and other consumer loans. These credits, while making up a small portion of the loan portfolio, demand the same emphasis on underwriting and credit evaluation as other types of loans advanced by the Bank. Approximately 2% of the loan portfolio consists of residential mortgage loans. The repricing duration of these loans was 19 months. These credits represent first liens on residential property loans originated by the Bank. While the Bank’s general practice is to originate and sell (servicing released) loans made by its Residential Lending department, from time to time certain loan characteristics do not meet the requirements of third party investors and these loans are instead maintained in the Bank’s portfolio until they are resold to another investor at a later date or mature. Loans are secured primarily by duly recorded first deeds of trust or mortgages. In some cases, the Bank may accept a recorded junior trust position. In general, borrowers will have a proven ability to build, lease, manage and/or sell a commercial or residential project and demonstrate satisfactory financial condition. Additionally, an equity contribution toward the project is customarily required. Construction loans require that the financial condition and experience of the general contractor and major subcontractors be satisfactory to the Bank. Guaranteed, fixed price contracts are required whenever appropriate, along with payment and performance bonds or completion bonds for larger scale projects. Loans intended for residential land acquisition, lot development and construction are made on the premise that the land: 1) is or will be developed for building sites for residential structures, and; 2) will ultimately be utilized for construction or improvement of residential zoned real properties, including the creation of housing. Residential development and construction loans will finance projects such as single family subdivisions, planned unit developments, townhouses, and condominiums. Residential land acquisition, development and construction loans generally are underwritten with a maximum term of 36 months, including extensions approved at origination. Commercial land acquisition and construction loans are secured by real property where loan funds will be used to acquire land and to construct or improve appropriately zoned real property for the creation of income producing or owner user commercial properties. Borrowers are generally required to put equity into each project at levels determined by the appropriate Loan Committee. Commercial land acquisition and construction loans generally are underwritten with a maximum term of 24 months. Substantially all construction draw requests must be presented in writing on American Institute of Architects documents and certified either by the contractor, the borrower and/or the borrower’s architect. Each draw request shall also include the borrower’s soft cost breakdown certified by the borrower or their Chief Financial Officer. Prior to an advance, the Bank or its contractor inspects the project to determine that the work has been completed, to justify the draw requisition. Commercial permanent loans are generally secured by improved real property which is generating income in the normal course of operation. Debt service coverage, assuming stabilized occupancy, must be satisfactory to support a permanent loan. The debt service coverage ratio is ordinarily at least 1.15 to 1.0. As part of the underwriting process, debt service coverage ratios are stress tested assuming a 200 basis point increase in interest rates from their current levels. Commercial permanent loans generally are underwritten with a term not greater than 10 years or the remaining useful life of the property, whichever is lower. The preferred term is between 5 to 7 years, with amortization to a maximum of 25 years. The Company’s loan portfolio includes ADC real estate loans including both investment and owner occupied projects. ADC loans amounted to $1.43 billion at March 31, 2018. A portion of the ADC portfolio, both speculative and non-speculative, includes loan funded interest reserves at origination. ADC loans that provide for the use of interest reserves represent approximately 81% of the outstanding ADC loan portfolio at March 31, 2018. The decision to establish a loan-funded interest reserve is made upon origination of the ADC loan and is based upon a number of factors considered during underwriting of the credit including: (1) the feasibility of the project; (2) the experience of the sponsor; (3) the creditworthiness of the borrower and guarantors; (4) borrower equity contribution; and (5) the level of collateral protection. When appropriate, an interest reserve provides an effective means of addressing the cash flow characteristics of a properly underwritten ADC loan. The Company does not significantly utilize interest reserves in other loan products. The Company recognizes that one of the risks inherent in the use of interest reserves is the potential masking of underlying problems with the project and/or the borrower’s ability to repay the loan. In order to mitigate this inherent risk, the Company employs a series of reporting and monitoring mechanisms on all ADC loans, whether or not an interest reserve is provided, including: (1) construction and development timelines which are monitored on an ongoing basis which track the progress of a given project to the timeline projected at origination; (2) a construction loan administration department independent of the lending function; (3) third party independent construction loan inspection reports; (4) monthly interest reserve monitoring reports detailing the balance of the interest reserves approved at origination and the days of interest carry represented by the reserve balances as compared to the then current anticipated time to completion and/or sale of speculative projects; and (5) quarterly commercial real estate construction meetings among senior Company management, which includes monitoring of current and projected real estate market conditions. If a project has not performed as expected, it is not the customary practice of the Company to increase loan funded interest reserves. The following tables detail activity in the allowance for credit losses by portfolio segment for the three months ended March 31, 2018 and 2017. Allocation of a portion of the allowance to one category of loans does not preclude its availability to absorb losses in other categories.

The Company’s primary credit quality indicators are to use an internal credit risk rating system that categorizes loans into pass, watch, special mention, or classified categories. Credit risk ratings are applied individually to those classes of loans that have significant or unique credit characteristics that benefit from a case-by-case evaluation. These are typically loans to businesses or individuals in the classes which comprise the commercial portfolio segment. Groups of loans that are underwritten and structured using standardized criteria and characteristics, such as statistical models (e.g., credit scoring or payment performance), are typically risk rated and monitored collectively. These are typically loans to individuals in the classes which comprise the consumer portfolio segment. The following are the definitions of the Company’s credit quality indicators: Pass: Loans in all classes that comprise the commercial and consumer portfolio segments that are not adversely rated, are contractually current as to principal and interest, and are otherwise in compliance with the contractual terms of the loan agreement. Management believes that there is a low likelihood of loss related to those loans that are considered pass. Watch: Loan paying as agreed with generally acceptable asset quality; however the obligor’s performance has not met expectations. Balance sheet and/or income statement has shown deterioration to the point that the obligor could not sustain any further setbacks. Credit is expected to be strengthened through improved obligor performance and/or additional collateral within a reasonable period of time. Special Mention: Loans in the classes that comprise the commercial portfolio segment that have potential weaknesses that deserve management’s close attention. If not addressed, these potential weaknesses may result in deterioration of the repayment prospects for the loan. The special mention credit quality indicator is not used for classes of loans that comprise the consumer portfolio segment. Management believes that there is a moderate likelihood of some loss related to those loans that are considered special mention. Classified: Classified (a) Substandard Classified (b) Doubtful The Company’s credit quality indicators are updated generally on a quarterly basis, but no less frequently than annually. The following table presents by class and by credit quality indicator, the recorded investment in the Company’s loans and leases as of March 31, 2018 and December 31, 2017. Watch and Total (dollars in thousands) Pass Special Mention Substandard Doubtful Loans March 31, 2018 Commercial $ 1,381,816 $ 28,758 $ 15,468 $ — $ 1,426,042 Income producing - commercial real estate 3,123,614 4,490 9,394 — 3,137,498 Owner occupied - commercial real estate 756,551 36,425 7,771 — 800,747 Real estate mortgage – residential 101,831 650 1,451 — 103,932 Construction - commercial and residential 1,036,106 — 4,707 — 1,040,813 Home equity 89,091 686 494 — 90,271 Other consumer 3,131 1 91 — 3,223 Total $ 6,492,140 $ 71,010 $ 39,376 $ — $ 6,602,526 December 31, 2017 Commercial $ 1,333,050 $ 34,163 $ 8,726 $ — $ 1,375,939 Income producing - commercial real estate 3,033,046 3,856 10,192 — 3,047,094 Owner occupied - commercial real estate 696,754 53,189 5,501 — 755,444 Real estate mortgage – residential 103,220 659 478 — 104,357 Construction - commercial and residential 1,027,123 — 4,709 — 1,031,832 Home equity 92,084 686 494 — 93,264 Other consumer 3,505 2 91 — 3,598 Total $ 6,288,782 $ 92,555 $ 30,191 $ — $ 6,411,528 Nonaccrual and Past Due Loans Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Loans are placed on nonaccrual status when, in management’s opinion, the borrower may be unable to meet payment obligations as they become due, as well as when required by regulatory provisions. Loans may be placed on nonaccrual status regardless of whether or not such loans are considered past due. Interest income is subsequently recognized only to the extent cash payments are received in excess of principal due. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. The following table presents, by class of loan, information related to nonaccrual loans as of March 31, 2018 and December 31, 2017.

Impairment is evaluated in total for smaller-balance loans of a similar nature and on an individual loan basis for other loans. If a loan is impaired, a specific valuation allowance is allocated, if necessary, so that the loan is reported net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral. Interest payments on impaired loans are typically applied to principal unless collectability of the principal amount is reasonably assured, in which case interest is recognized on a cash basis. Impaired loans, or portions thereof, are charged off when deemed uncollectible. The following table presents, by class of loan, information related to impaired loans for the periods ended March 31, 2018 and March 31, 2017.

The Company offers various types of concessions when modifying a loan. Commercial and industrial loans modified in a TDR often involve temporary interest-only payments, term extensions, and converting revolving credit lines to term loans. Additional collateral, a co-borrower, or a guarantor is often requested. Commercial mortgage and construction loans modified in a TDR often involve reducing the interest rate for the remaining term of the loan, extending the maturity date at an interest rate lower than the current market rate for new debt with similar risk, or substituting or adding a new borrower or guarantor. Construction loans modified in a TDR may also involve extending the interest-only payment period. As of March 31, 2018, all performing TDRs were categorized as interest-only modifications. Loans modified in a TDR for the Company may have the financial effect of increasing the specific allowance associated with the loan. An allowance for impaired consumer and commercial loans that have been modified in a TDR is measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s observable market price, or the estimated fair value of the collateral, less any selling costs, if the loan is collateral dependent. Management exercises significant judgment in developing these estimates. The following table presents by class, the recorded investment of loans modified in TDRs held by the Company during the three months ended March 31, 2018 and 2017. For the Three Months Ended March 31, 2018 (dollars in thousands) Number of Contracts Commercial Income Producing - Commercial Real Estate Owner Occupied - Commercial Real Estate Construction - Commercial Real Estate Total Troubled debt restructings Restructured accruing 8 $ 1,230 $ 9,198 $ 1,071 $ — $ 11,499 Restructured nonaccruing 5 1,649 — — — 1,649 Total 13 $ 2,879 $ 9,198 $ 1,071 $ — $ 13,148 Specific allowance $ 595 $ 2,350 $ — $ — $ 2,945 Restructured and subsequently defaulted $ — $ 121 $ — $ — $ 121 For the Three Months Ended March 31, 2017 (dollars in thousands) Number of Contracts Commercial Income Producing - Commercial Real Estate Owner Occupied - Commercial Real Estate Construction - Commercial Real Estate Total Troubled debt restructings Restructured accruing 7 $ 3,137 $ 4,397 $ 367 $ — $ 7,901 Restructured non-accruing 2 193 — — 702 895 Total 9 $ 3,330 $ 4,397 $ 367 $ 702 $ 8,796 Specific allowance $ 855 $ 1,100 $ — $ — $ 1,955 Restructured and subsequently defaulted $ 237 $ — $ — $ — $ 237 The Company had thirteen TDR’s at March 31, 2018 totaling approximately $13.1 million. Eight of these loans totaling approximately $11.5 million, are performing under their modified terms. During the three months of 2018, there was one default on a $121 thousand restructured loan which was charged off, as compared to the same period in 2017, which had one default on a $237 thousand restructured loan. A default is considered to have occurred once the TDR is past due 90 days or more or it has been placed on nonaccrual. There was one performing TDR totaling $786 thousand that was reclassified to nonperforming loans during the three months ended March 31, 2018, as compared to the same period in 2017, which had no performing TDRs reclassified to nonperforming loans. Commercial and consumer loans modified in a TDR are closely monitored for delinquency as an early indicator of possible future default. If loans modified in a TDR subsequently default, the Company evaluates the loan for possible further impairment. The allowance may be increased, adjustments may be made in the allocation of the allowance, or partial charge-offs may be taken to further write-down the carrying value of the loan. There were no loans modified in a TDR during the three months ended March 31, 2018 and 2017.

Interest Rate Swap Derivatives

Interest Rate Swap Derivatives	3 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Interest Rate Swap Derivatives	Note 6. Interest Rate Swap Derivatives The Company uses interest rate swap agreements to assist in its interest rate risk management. The Company’s objective in using interest rate derivatives designated as cash flow hedges is to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company entered into forward starting interest rate swaps in April 2015 as part of its interest rate risk management strategy intended to mitigate the potential risk of rising interest rates on the Bank’s cost of funds. The notional amounts of the interest rate swaps designated as cash flow hedges do not represent amounts exchanged by the counterparties, but rather, the notional amount is used to determine, along with other terms of the derivative, the amounts to be exchanged between the counterparties. The interest rate swaps are designated as cash flow hedges and involve the receipt of variable rate amounts from two counterparties in exchange for the Company making fixed payments beginning in April 2016. The Company’s intent is to hedge its exposure to the variability in potential future interest rate conditions on existing financial instruments. As of March 31, 2018, the Company had three forward starting designated cash flow hedge interest rate swap transactions outstanding that had an aggregate notional amount of $250 million associated with the Company’s variable rate deposits. The net unrealized gain before income tax on the swaps was $4.8 million at March 31, 2018 compared to a net unrealized gain before income tax of $2.3 million at December 31, 2017. The gain in value since year end 2017 is due to the increase in expected net cash inflows from the swap over its remaining term due to higher market interest rates. For derivatives designated as cash flow hedges, changes in the fair value of the derivative are initially reported in other comprehensive income (outside of earnings), net of tax, and subsequently reclassified to earnings when the hedged transaction affects earnings. The Company assesses the effectiveness of each hedging relationship by comparing the changes in cash flows of the derivative hedging instrument with the changes in cash flows of the designated hedged transactions. Amounts reported in accumulated other comprehensive income related to designated cash flow hedge derivatives will be reclassified to interest income/expense as interest payments are made/received on the Company’s variable-rate assets/liabilities. During the quarter ended March 31, 2018, the Company reclassified $88 thousand related to designated cash flow hedge derivatives from accumulated other comprehensive income to interest expense. During the next twelve months, the Company estimates (based on existing interest rates) that $923 thousand will be reclassified as a decrease in interest expense. The Company is exposed to credit risk in the event of nonperformance by the interest rate swap counterparty. The Company minimizes this risk by entering into derivative contracts with only large, stable financial institutions, and the Company has not experienced, and does not expect, any losses from counterparty nonperformance on the interest rate swaps. The Company monitors counterparty risk in accordance with the provisions of ASC Topic 815, “Derivatives and Hedging.” The designated cash flow hedge interest rate swap agreements detail: 1) that collateral be posted when the market value exceeds certain threshold limits associated with the secured party’s exposure; 2) if the Company defaults on any of its indebtedness (including default where repayment of the indebtedness has not been accelerated by the lender), then the Company could also be declared in default on its derivative obligations; 3) if the Company fails to maintain its status as a well capitalized institution then the counterparty could terminate the derivative positions and the Company would be required to settle its obligations under the agreements. As of March 31, 2018, the aggregate fair value of all designated cash flow hedge derivative contracts with credit risk contingent features (i.e., those containing collateral posting or termination provisions based on our capital status) that were in a net asset position totaled $4.8 million (none of these contracts were in a net liability position as of March 31, 2018). The Company has minimum collateral posting thresholds with certain of its derivative counterparties. As of March 31, 2018, the Company was not required to post collateral with its derivative counterparties against its obligations under these agreements because these agreements were in a net asset position. If the Company had breached any provisions under the agreements at March 31, 2018, it could have been required to settle its obligations under the agreements at the termination value. The table below identifies the balance sheet category and fair values of the Company’s designated cash flow hedge derivative instruments as of March 31, 2018 and December 31, 2017.

Stock-Based Compensation	Note 10. Stock-Based Compensation The Company maintains the 2016 Stock Plan (“2016 Plan”), the 2006 Stock Plan (“2006 Plan”) and the 2011 Employee Stock Purchase Plan (“2011 ESPP”). In connection with the acquisition of Virginia Heritage, the Company assumed the Virginia Heritage 2006 Stock Option Plan and the 2010 Long Term Incentive Plan (the “Virginia Heritage Plans”). No additional options may be granted under the 2006 Plan or the Virginia Heritage Plans. The Company adopted the 2016 Plan upon approval by the shareholders at the 2016 Annual Meeting held on May 12, 2016. The 2016 Plan provides directors and selected employees of the Bank, the Company and their affiliates with the opportunity to acquire shares of stock, through awards of options, time vested restricted stock, performance-based restricted stock and stock appreciation rights. Under the 2016 Plan, 1,000,000 shares of common stock were initially reserved for issuance. For awards that are service based, compensation expense is being recognized over the service (vesting) period based on fair value, which for stock option grants is computed using the Black-Scholes model. For restricted stock awards granted under the 2016 plan, fair value is based on the Company’s closing price on the date of grant. For awards that are performance-based, compensation expense is recorded based on the probability of achievement of the goals underlying the grant. For restricted stock awards granted under the 2006 plan, fair value is based on the average of the high and low stock price of the Company’s shares on the date of grant. In February 2018, the Company awarded 94,344 shares of time vested restricted stock to senior officers, directors, and certain employees. The shares vest in three substantially equal installments beginning on the first anniversary of the date of grant. In February 2018, the Company awarded senior officers a targeted number of 42,533 performance vested restricted stock units (PRSUs). The vesting of PRSUs is 100% after three years with payouts based on threshold, target or maximum average performance targets over the three year period relative to a peer index. There are two performance metrics: 1) average annual earnings per share growth; and 2) average annual return on average assets. Each metric is measured against companies in the KBW Regional Banking Index. The Company has unvested restricted stock awards and PRSU grants of 274,796 shares at March 31, 2018. Unrecognized stock based compensation expense related to restricted stock awards and PRSU grants totaled $13.5 million at March 31, 2018. At such date, the weighted-average period over which this unrecognized expense was expected to be recognized was 2.33 years.

The total fair value of stock options vested was $34 thousand for both the three months ended March 31, 2018 and 2017. Unrecognized stock-based compensation expense related to stock options totaled $57 thousand at March 31, 2018. At such date, the weighted-average period over which this unrecognized expense was expected to be recognized was 1.76 years. Approved by shareholders in May 2011, the 2011 ESPP reserved 550,000 shares of common stock (as adjusted for stock dividends) for issuance to employees. Whole shares are sold to participants in the plan at 85% of the lower of the stock price at the beginning or end of each quarterly offering period. The 2011 ESPP is available to all eligible employees who have completed at least one year of continuous employment, work at least 20 hours per week and at least five months a year. Participants may contribute a minimum of $10 per pay period to a maximum of $6,250 per offering period or $25,000 annually (not to exceed more than 10% of compensation per pay period). At March 31, 2018, the 2011 ESPP had 399,383 shares reserved for issuance. Included in salaries and employee benefits in the accompanying Consolidated Statements of Operations, the Company recognized $1.5 million and $1.9 million in stock-based compensation expense for the three months ended March 31, 2018 and 2017, respectively. Stock-based compensation expense is recognized ratably over the requisite service period for all awards.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 12. Fair Value Measurements The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. ASC Topic 820, “Fair Value Measurements and Disclosures,” Level 1 Quoted prices in active exchange markets for identical assets or liabilities; also includes certain U.S. Treasury and other U.S. Government and agency securities actively traded in over-the-counter markets. Level 2 Observable inputs other than Level 1 including quoted prices for similar assets or liabilities, quoted prices in less active markets, or other observable inputs that can be corroborated by observable market data; also includes derivative contracts whose value is determined using a pricing model with observable market inputs or can be derived principally from or corroborated by observable market data. This category generally includes certain U.S. Government and agency securities, corporate debt securities, derivative instruments, and residential mortgage loans held for sale. Level 3 Unobservable inputs supported by little or no market activity for 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; also includes observable inputs for single dealer nonbinding quotes not corroborated by observable market data. This category generally includes certain private equity investments, retained interests from securitizations, and certain collateralized debt obligations.

Fair value is the amount at which a financial instrument could be exchanged in a current transaction between willing parties, other than in a forced sale or liquidation, and is best evidenced by quoted market price, if one exists. Quoted market prices, if available, are shown as estimates of fair value. Because no quoted market prices exist for a portion of the Company’s financial instruments, the fair value of such instruments has been derived based on management’s assumptions with respect to future economic conditions, the amount and timing of future cash flows and estimated discount rates. Different assumptions could significantly affect these estimates. Accordingly, the net realizable value could be materially different from the estimates presented below. In addition, the estimates are only indicative of individual financial instrument values and should not be considered an indication of the fair value of the Company taken as a whole. The following methods and assumptions were used to estimate the fair value of each category of financial instrument for which it is practicable to estimate value: Cash due from banks and federal funds sold: Interest bearing deposits with other banks: Investment securities: Federal Reserve and Federal Home Loan Bank stock: Loans held for sale: Loans: Bank owned life insurance: Annuity investment: Mortgage banking derivatives: Interest rate swap derivatives: Noninterest bearing deposits: Interest bearing deposits: Certificates of deposit: Customer repurchase agreements: Borrowings: Off-balance sheet items: The estimated fair values of the Company’s financial instruments at March 31, 2018 and December 31, 2017 are as follows: Fair Value Measurements Quoted Prices Significant Other Observable Inputs Significant Unobservable Inputs (dollars in thousands) Carrying Value Fair Value (Level 1) (Level 2) (Level 3) March 31, 2018 Assets Cash and due from banks $ 7,954 $ 7,954 $ — $ 7,954 $ — Federal funds sold 29,552 29,552 — 29,552 — Interest bearing deposits with other banks 167,347 167,347 — 167,347 — Investment securities 578,317 578,317 — 576,599 1,718 Federal Reserve and Federal Home Loan Bank stock 34,768 34,768 — 34,768 — Loans held for sale 25,873 25,873 — 25,873 — Loans (1) 6,536,719 6,564,036 — — 6,564,036 Bank owned life insurance 61,291 61,291 — 61,291 — Annuity investment 11,463 11,463 — 11,463 — Mortgage banking derivatives 51 51 — — 51 Interst rate swap derivatives 4,788 4,788 — 4,788 — Liabilities Noninterest bearing deposits 1,909,210 1,909,210 — 1,909,210 — Interest bearing deposits 3,134,707 3,134,707 — 3,134,707 — Certificates of deposit 1,077,884 1,074,200 — 1,074,200 — Customer repurchase agreements 48,365 48,365 — 48,365 — Borrowings 492,003 497,066 — 497,066 — Mortgage banking derivatives 84 84 — — 84 December 31, 2017 Assets Cash and due from banks $ 7,445 $ 7,445 $ — $ 7,445 $ — Federal funds sold 15,767 15,767 — 15,767 — Interest bearing deposits with other banks 167,261 167,261 — 167,261 — Investment securities 589,268 589,268 — 587,550 1,718 Federal Reserve and Federal Home Loan Bank stock 36,324 36,324 — 36,324 — Loans held for sale 25,096 25,096 — 25,096 — Loans (2) 6,346,770 6,381,213 — — 6,381,213 Bank owned life insurance 60,947 60,947 — 60,947 — Annuity investment 11,632 11,632 — 11,632 — Mortgage banking derivatives 43 43 — — 43 Interst rate swap derivatives 2,256 2,256 — 2,256 — Liabilities Noninterest bearing deposits 1,982,912 1,982,912 — 1,982,912 — Interest bearing deposits 3,041,563 3,041,563 — 3,041,563 — Certificates of deposit 829,509 829,886 — 829,886 — Customer repurchase agreements 76,561 76,561 — 76,561 — Borrowings 541,905 533,162 — 533,162 — Mortgage banking derivatives 10 10 — — 10 (1) Carrying amount is net of unearned income and the allowance for credit losses.

Supplemental Executive Retirement Plan
Supplemental Executive Retirement Plan	Note 13. Supplemental Executive Retirement Plan The Bank has entered into Supplemental Executive Retirement and Death Benefit Agreements (the “SERP Agreements”) with certain of the Bank’s executive officers other than Mr. Paul, which upon the executive’s retirement, will provide for a stated monthly payment for such executive’s lifetime subject to certain death benefits described below. The retirement benefit is computed as a percentage of each executive’s projected average base salary over the five years preceding retirement, assuming retirement at age 67. The SERP Agreements provide that (a) the benefits vest ratably over six years of service to the Bank, with the executive receiving credit for years of service prior to entering into the SERP Agreement, (b) death, disability and change-in-control shall result in immediate vesting, and (c) the monthly amount will be reduced if retirement occurs earlier than age 67 for any reason other than death, disability or change-in-control. The SERP Agreements further provide for a death benefit in the event the retired executive dies prior to receiving 180 monthly installments, paid either in a lump sum payment or continued monthly installment payments, such that the executive’s beneficiary has received payment(s) sufficient to equate to a cumulative 180 monthly installments. The SERP Agreements are unfunded arrangements maintained primarily to provide supplemental retirement benefits and comply with Section 409A of the Internal Revenue Code. The Bank financed the retirement benefits by purchasing fixed annuity contracts with four insurance carriers in 2013 totaling $11.4 million that have been designed to provide a future source of funds for the lifetime retirement benefits of the SERP Agreements. The primary impetus for utilizing fixed annuities is a substantial savings in compensation expenses for the Bank as opposed to a traditional SERP Agreement. For the quarter ended March 31, 2018, the annuity contracts accrued $27 thousand of income, which was included in other noninterest income on the Consolidated Statement of Operations. The cash surrender value of the annuity contracts was $11.5 million and $11.6 million at March 31, 2018 and December 31, 2017, respectively and is included in other assets on the Consolidated Balance Sheet. For the three months ended March 31, 2018 and 2017, the Company recorded benefit expense accruals of $100 thousand and $103 thousand for this post retirement benefit. Upon death of a named executive, the annuity contract related to such executive terminates. The Bank has purchased additional bank owned life insurance contracts, which would effectively finance payments (up to a 15 year certain amount) to the executives’ named beneficiaries.

Summary of Significant Accoun21

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2018
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Consolidated Financial Statements include the accounts of Eagle Bancorp, Inc. and its subsidiaries (the “Company”), EagleBank (the “Bank”), Eagle Commercial Ventures, LLC (“ECV”), Eagle Insurance Services, LLC, and Bethesda Leasing, LLC, 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, 2017 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. 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, 2017. 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, 2017. Operating results for the three months ended March 31, 2018 are not necessarily indicative of the results of operations to be expected for the remainder of the year, or for any other period.
Use of Estimates	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	New Authoritative Accounting Guidance Accounting Standards Adopted in 2018 ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” The majority of our revenue-generating transactions are not subject to ASC 606, including revenue generated from financial instruments, such as our loans, letters of credit, derivatives and investment securities, as well as revenue related to our mortgage servicing activities, as these activities are subject to other GAAP discussed elsewhere within our disclosures. Substantially all of the Company’s revenue is generated from contracts with customers. Descriptions of our revenue-generating activities that are within the scope of ASC 606, which are presented in our income statements as components of noninterest income are as follows: ● Service charges on deposit accounts - these represent general service fees for monthly account maintenance and activity- or transaction-based fees and consist of transaction-based revenue, time-based revenue (service period), item-based revenue or some other individual attribute-based revenue. Revenue is recognized when our performance obligation is completed which is generally monthly for account maintenance services or when a transaction has been completed (such as a wire transfer). Payment for such performance obligations are generally received at the time the performance obligations are satisfied. ● Other Fees – generally, the Company receives compensation when a customer that it refers opens an account with certain third-parties. This category includes credit card, investment advisory, and interchange fees. The timing and amount of revenue recognition is not materially impacted by the new standard. ● Sale of OREO – ASU 2014-09 prescribes derecognition requirements for the sale of OREO that are less prescriptive than existing derecognition requirements. Previously, the Company was required to assess 1) the adequacy of a buyer’s initial and continuing investments and 2) the seller’s continuing involvement with the property. ASU 2014-09 requires an entity to assess whether it is “probable” that it will collect the consideration to which it will be entitled in exchange for transferring the asset to the customer. The new requirements could result in earlier revenue recognition; however, such sales are infrequent and the impact of this change is not expected to be material to our financial statements. A contract asset balance occurs when an entity performs a service for a customer before the customer pays consideration (resulting in a contract receivable) or before payment is due (resulting in a contract asset). A contract liability balance is an entity’s obligation to transfer a service to a customer for which the entity has already received payment (or payment is due) from the customer. The Company’s noninterest revenue streams are largely based on transactional activity, or standard month-end revenue accruals based on fee schedules. Consideration is often received immediately or shortly after the Company satisfies its performance obligation and revenue is recognized. The Company does not typically enter into long-term revenue contracts with customers, and therefore, does not have contract balances material to our financial statements. As of March 31, 2018 and December 31, 2017, the Company did not have any significant contract balances. In connection with the adoption of Topic 606, an entity is required to capitalize, and subsequently amortize into expense, certain incremental costs of obtaining a contract with a customer if these costs are expected to be recovered. The incremental costs of obtaining a contract are those costs that an entity incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained (for example, sales commission). The Company utilizes the practical expedient which allows entities to immediately expense contract acquisition costs when the asset that would have resulted from capitalizing these costs would have been amortized in one year or less. Upon adoption of Topic 606, the Company did not capitalize any contract acquisition cost.
