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, 2016 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, 2016. 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, 2016. Operating results for the three and nine months ended September 30, 2017 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 the metropolitan Washington, D.C area. 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 FHA loans. The Bank offers its products and services through twenty-one 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, provides subordinated financing for the acquisition, development and construction of real estate projects; these transactions involve higher levels of risk, together with commensurate higher returns. Refer to Higher Risk Lending – Revenue Recognition below. 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. Cash Flows For purposes of reporting cash flows, cash and cash equivalents include cash and due from banks, federal funds sold, and interest bearing deposits with other banks which have an original maturity of three months or less. Investment Securities The Company has no securities classified as trading, or as held to maturity. Securities available-for-sale are acquired as part of the Company’s asset/liability management strategy and may be sold in response to changes in interest rates, current market conditions, loan demand, changes in prepayment risk and other factors. Securities available-for-sale are carried at fair value, with unrealized gains or losses being reported as accumulated other comprehensive income/(loss), a separate component of shareholders’ equity, net of deferred income tax. Realized gains and losses, using the specific identification method, are included as a separate component of noninterest income in the Consolidated Statements of Operations. Premiums and discounts on investment securities are amortized/accreted to the earlier of call or maturity based on expected lives, which lives are adjusted based on prepayment assumptions and call optionality if any. Declines in the fair value of individual available-for-sale securities below their cost that are other-than-temporary in nature result in write-downs of the individual securities to their fair value. Factors affecting the determination of whether other-than-temporary impairment has occurred include a downgrading of the security by a rating agency, a significant deterioration in the financial condition of the issuer, or a change in management’s intent and ability to hold a security for a period of time sufficient to allow for any anticipated recovery in fair value. Management systematically evaluates investment securities for other-than-temporary declines in fair value on a quarterly basis. This analysis requires management to consider various factors, which include the: (1) duration and magnitude of the decline in value; (2) financial condition of the issuer or issuers; and (3) structure of the security. The entire amount of an impairment loss is recognized in earnings only when: (1) the Company intends to sell the security; or (2) it is more likely than not that the Company will have to sell the security before recovery of its amortized cost basis; or (3) the Company does not expect to recover the entire amortized cost basis of the security. In all other situations, only the portion of the impairment loss representing the credit loss must be recognized in earnings, with the remaining portion being recognized in shareholders’ equity as comprehensive income, net of deferred taxes. Loans Held for Sale The Company regularly engages in sales of residential mortgage loans held for sale and the guaranteed portion of small business loans, guaranteed by the Small Business Administration (“SBA”), and originated by the Bank. The Company has elected to carry loans held for sale at fair value. Fair value is derived from secondary market quotations for similar instruments. Gains and losses on sales of these loans are recorded as a component of noninterest income in the Consolidated Statements of Operations. The Company’s current practice is to sell residential mortgage loans held for sale on a servicing released basis, and, therefore, it has no intangible asset recorded in the normal course of business for the value of such servicing as of September 30, 2017, December 31, 2016 and September 30, 2016. The sale of the guaranteed portion of SBA loans on a servicing retained basis, in a transaction apart from the loan’s origination, gives rise to an excess servicing asset, which is computed on a loan by loan basis with the unamortized amount being included in intangible assets in the Consolidated Balance Sheets. This excess servicing asset is being amortized on a straight-line basis (with adjustment for prepayments) as an offset to servicing fees collected and is included in other income in the Consolidated Statements of Operations. The Company enters into commitments to originate residential mortgage loans whereby the interest rate on the loan is determined prior to funding (i.e. interest rate lock commitments). Such interest rate lock commitments on mortgage loans to be sold in the secondary market are considered to be derivatives. To protect against the price risk inherent in residential mortgage loan commitments, the Company utilizes both “best efforts” and “mandatory delivery” forward loan sale commitments to mitigate the risk of potential decreases in the values of loans that would result from the exercise of the derivative loan commitments. Under a “best efforts” contract, the Company commits to deliver an individual mortgage loan of a specified principal amount and quality to an investor and the investor commits to a price that it will purchase the loan from the Company if the loan to the underlying borrower closes. The Company protects itself from changes in interest rates through the use of best efforts forward delivery commitments, whereby the investor commits to purchase a loan at a price representing a premium on the day the borrower commits to an interest rate with the intent that the buyer/investor has assumed the interest rate risk on the loan. As a result, the Bank is not generally exposed to losses on loans sold utilizing best efforts, nor will it realize gains related to rate lock commitments due to changes in interest rates. The market values of interest rate lock commitments and best efforts contracts are not readily ascertainable with precision because rate lock commitments and best efforts contracts are not actively traded. Because of the high correlation between rate lock commitments and best efforts contracts, no gain or loss should occur on the interest rate lock commitments. Under a “mandatory delivery” contract, the Company commits to deliver a certain principal amount of mortgage loans to an investor at a specified price on or before a specified date. If the Company fails to deliver the amount of mortgages necessary to fulfill the commitment by the specified date, it is obligated to pay the investor a “pair-off” fee, based on then-current market prices, to compensate the investor for the shortfall. The Company manages the interest rate risk on interest rate lock commitments by entering into forward sale contracts of mortgage backed securities, whereby the Company obtains the right to deliver securities to investors in the future at a specified price. Such contracts are accounted for as derivatives and are recorded at fair value in derivative assets or liabilities, carried on the Consolidated Balance Sheet within other assets or other liabilities with changes in fair value recorded in other income within the Consolidated Statements of Operations. The period of time between issuance of a loan commitment to the customer and closing and sale of the loan to an investor generally ranges from 30 to 90 days under current market conditions. The gross gains on loan sales are recognized based on new loan commitments with adjustment for price and pair-off activity. Commission expenses on loans held for sale are recognized based on loans closed. In circumstances where the Company does not deliver the whole loan to an investor, but rather elects to retain the loan in its portfolio, the loan is transferred from held for sale to loans at fair value at date of transfer. The Company originates a small number of FHA loans through the Department of Housing and Urban Development’s Multifamily Accelerated Program (“MAP”). The Company securitizes these loans through the Government National Mortgage Association (“Ginnie Mae”) MBS I program and sells the resulting securities in the open market to authorized dealers in the normal course of business and generally retains the servicing rights. When servicing is retained on FHA loans securitized and sold, the Company computes an excess servicing asset on a loan by loan basis with the unamortized amount being included in intangible assets in the Consolidated Balance Sheets. Revenue represents gains from the sale of the Ginnie Mae securities and net revenues earned on the servicing of FHA loans securitizing the Ginnie Mae securities. The gains on Ginnie Mae securities include the realized and unrealized gains and losses on sales of FHA mortgage loans, as well as the changes in fair value of FHA interest rate lock commitments and FHA forward loan sale commitments. Revenue from servicing commercial FHA mortgages is recognized as earned based on the specific contractual terms of the underlying servicing agreements, along with amortization of and changes in impairment of mortgage servicing rights. Loans Loans are stated at the principal amount outstanding, net of unamortized deferred costs and fees. Interest income on loans is accrued at the contractual rate on the principal amount outstanding. It is the Company’s policy to discontinue the accrual of interest when circumstances indicate that collection is doubtful. Deferred fees and costs are being amortized on the interest method over the term of the loan. Management considers loans impaired when, based on current information, it is probable that the Company will not collect all principal and interest payments according to contractual terms. Loans are evaluated for impairment in accordance with the Company’s portfolio monitoring and ongoing risk assessment procedures. Management considers the financial condition of the borrower, cash flow of the borrower, payment status of the loan, and the value of the collateral, if any, securing the loan. Generally, impaired loans do not include large groups of smaller balance homogeneous loans such as residential real estate and consumer type loans which are evaluated collectively for impairment and are generally placed on nonaccrual when the loan becomes 90 days past due as to principal or interest. Loans specifically reviewed for impairment are not considered impaired during periods of “minimal delay” in payment (90 days or less) provided eventual collection of all amounts due is expected. The impairment of a loan is measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, or the fair value of the collateral if repayment is expected to be provided solely by the collateral. In appropriate circumstances, interest income on impaired loans may be recognized on a cash basis. Higher Risk Lending – Revenue Recognition The Company had occasionally made higher risk acquisition, development, and construction (“ADC”) loans that entailed higher risks than ADC loans made following normal underwriting practices (“higher risk loan transactions”). These higher risk loan transactions were made through the Company’s subsidiary, ECV. This activity was limited as to individual transaction amount and total exposure amounts, based on capital levels, and is carefully monitored. The loans are carried on the balance sheet at amounts outstanding. ECV had three higher risk loan transactions outstanding as of September 30, 2017 and December 31, 2016, amounting to $9.5 million and $9.3 million, respectively. Allowance for Credit Losses The allowance for credit losses represents an amount which, in management’s judgment, is adequate to absorb probable losses on loans and other extensions of credit that may become uncollectible. The adequacy of the allowance for credit losses is determined through careful and continuous review and evaluation of the loan portfolio and involves the balancing of a number of factors to establish a prudent level of allowance. Among the factors considered in evaluating the adequacy of the allowance for credit losses are lending risks associated with growth and entry into new markets, loss allocations for specific credits, the level of the allowance to nonperforming loans, historical loss experience, economic conditions, portfolio trends and credit concentrations, changes in the size and character of the loan portfolio, and management’s judgment with respect to current and expected economic conditions and their impact on the existing loan portfolio. Allowances for impaired loans are generally determined based on collateral values. Loans or any portion thereof deemed uncollectible are charged against the allowance, while recoveries are credited to the allowance. Management adjusts the level of the allowance through the provision for credit losses, which is recorded as a current period operating expense. The allowance for credit losses consists of allocated and unallocated components. The components of the allowance for credit losses represent an estimation done pursuant to Accounting Standards Codification (“ASC”) Topic 450, “Contingencies,” “Receivables.” Management believes that the allowance for credit losses is adequate; however, determination of the allowance is inherently subjective and requires significant estimates. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic conditions. Evaluation of the potential effects of these factors on estimated losses involves a high degree of uncertainty, including the strength and timing of economic cycles and concerns over the effects of a prolonged economic downturn in the current cycle. In addition, various banking agencies, as an integral part of their examination process, and independent consultants engaged by the Bank, periodically review the Bank’s loan portfolio and allowance for credit losses. Such review may result in recognition of additions to the allowance based on their judgments of information available to them at the time of their examination. Premises and Equipment Premises and equipment are stated at cost less accumulated depreciation and amortization computed using the straight-line method for financial reporting purposes. Premises and equipment are depreciated over the useful lives of the assets, which generally range from three to seven years for furniture, fixtures and equipment, three to five years for computer software and hardware, and five to twenty years for building improvements. Leasehold improvements are amortized over the terms of the respective leases, which may include renewal options where management has the positive intent to exercise such options, or the estimated useful lives of the improvements, whichever is shorter. The costs of major renewals and betterments are capitalized, while the costs of ordinary maintenance and repairs are expensed as incurred. These costs are included as a component of premises and equipment expenses on the Consolidated Statements of Operations. Other Real Estate Owned (OREO) Assets acquired through loan foreclosure are held for sale and are recorded at fair value less estimated selling costs when acquired, establishing a new cost basis. The new basis is supported by appraisals that are generally no more than twelve months old. Costs after acquisition are generally expensed. If the fair value of the asset declines, a write-down is recorded through noninterest expense. The valuation of foreclosed assets is subjective in nature and may be adjusted in the future because of changes in market conditions or appraised values. Goodwill and Other Intangible Assets Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Other intangible assets represent purchased assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights. Intangible assets that have finite lives, such as core deposit intangibles, are amortized over their estimated useful lives and subject to periodic impairment testing. Intangible assets (other than goodwill) are amortized to expense using accelerated or straight-line methods over their respective estimated useful lives. Goodwill is subject to impairment testing at the reporting unit level, which must be conducted at least annually. The Company performs impairment testing during the fourth quarter of each year or when events or changes in circumstances indicate the assets might be impaired. The Company performs a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing updated qualitative factors, the Company determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, it does not have to perform the two-step goodwill impairment test. Determining the fair value of a reporting unit under the first step of the goodwill impairment test and determining the fair value of individual assets and liabilities of a reporting unit under the second step of the goodwill impairment test are judgmental and often involve the use of significant estimates and assumptions. Similarly, estimates and assumptions are used in determining the fair value of other intangible assets. Estimates of fair value are primarily determined using discounted cash flows, market comparisons and recent transactions. These approaches use significant estimates and assumptions including projected future cash flows, discount rates reflecting the market rate of return, projected growth rates and determination and evaluation of appropriate market comparables. Based on the results of qualitative assessments of all reporting units, the Company concluded that no impairment existed at December 31, 2016. However, future events could cause the Company to conclude that goodwill or other intangibles have become impaired, which would result in recording an impairment loss. Any resulting impairment loss could have a material adverse impact on the Company’s financial condition and results of operations. Interest Rate Swap Derivatives The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities and through the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments designated as cash flow hedges are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to certain variable rate deposits. Refer to the “Loans Held for Sale” section for a discussion on forward commitment contracts, which are also considered derivatives. At the inception of a derivative contract, the Company designates the derivative as one of three types based on the Company’s intentions and belief as to likely effectiveness as a hedge. These three types are (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (“fair value hedge”), (2) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedge”), or (3) an instrument with no hedging designation (“stand-alone derivative”). Regarding Interest Rate Swap Derivatives, the Company has no fair value hedges, only cash flow hedges. For a cash flow hedge, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same period(s) during which the hedged transaction affects earnings (i.e. the period when cash flows are exchanged between counterparties). For both fair value and cash flow hedges, changes in the fair value of derivatives that are not highly effective in hedging the changes in fair value or expected cash flows of the hedged item are recognized immediately in current earnings. Changes in the fair value of derivatives that do not qualify for hedge accounting are reported currently in earnings, as noninterest income. Net cash settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in noninterest income. Cash flows on hedges are classified in the cash flow statement the same as the cash flows of the items being hedged. The Company formally documents the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions at the inception of the hedging relationship. This documentation includes linking fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used are highly effective in offsetting changes in fair values or cash flows of the hedged items. The Company discontinues hedge accounting when it determines that the derivative is no longer highly effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm, or treatment of the derivative as a hedge is no longer appropriate or intended. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as noninterest income or expense. When a fair value hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted over the remaining life of the asset or liability. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that were accumulated in other comprehensive income are amortized into earnings over the same periods in which the hedged transactions will affect earnings. Customer Repurchase Agreements The Company enters into agreements under which it sells securities subject to an obligation to repurchase the same securities. Under these arrangements, the Company may transfer legal control over the assets but still retain effective control through an agreement that both entitles and obligates the Company to repurchase the assets. As a result, securities sold under agreements to repurchase are accounted for as collateralized financing arrangements and not as a sale and subsequent repurchase of securities. The agreements are entered into primarily as accommodations for large commercial deposit customers. The obligation to repurchase the securities is reflected as a liability in the Company’s Consolidated Balance Sheets, while the securities underlying the securities sold under agreements to repurchase remain in the respective assets accounts and are delivered to and held as collateral by third party trustees. Marketing and Advertising Marketing and advertising costs are generally expensed as incurred. Income Taxes The Company employs the asset and liability method of accounting for income taxes as required by ASC Topic 740, “ Income Taxes Transfer of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. In certain cases, the recourse to the Bank to repurchase assets may exist but is deemed immaterial based on the specific facts and circumstances. Earnings per Common Share Basic net income per common share is derived by dividing net income by the weighted-average number of common shares outstanding during the period measured. Diluted earnings per common share is computed by dividing net income by the weighted-average number of common shares outstanding during the period measured including the potential dilutive effects of common stock equivalents.

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 2017, 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 September 30, 2017 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 3.5 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 September 30, 2017 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 September 30, 2017 and December 31, 2016 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 nine months ended September 30, 2016, gross realized gains on sales of investments securities were $1.3 million and gross realized losses on sales of investment securities were $202 thousand. Proceeds from sales and calls of investment securities for the nine months ended September 30, 2017 were $70.1 million, and in 2016 were $94.2 million. 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 September 30, 2017 was $459.9 million, which is well in excess of required amounts in order to operationally provide significant reserve amounts for new business. As of September 30, 2017 and December 31, 2016, 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

Mortgage Banking Derivative
Mortgage Banking Derivative	Note 4. 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 September 30, 2017 the Bank had mortgage banking derivative financial instruments with a notional value of $59.6 million related to its forward contracts as compared to $81.7 million at September 30, 2016. The fair value of these mortgage banking derivative instruments at September 30, 2017 was $63 thousand included in other assets and $36 thousand included in other liabilities as compared to $217 thousand included in other assets and $222 thousand included in other liabilities at September 30, 2016. Included in other noninterest income for the three and nine months ended September 30, 2017 was a net gain of $71 thousand and a net gain of $335 thousand, relating to mortgage banking derivative instruments as compared to a net loss of $46 thousand and a net gain of $274 thousand for the three and nine months ended September 30, 2016. The amount included in other noninterest income for the three and nine months ended September 30, 2017 pertaining to its mortgage banking hedging activities was a net realized loss of $14 thousand and $912 thousand as compared to a net realized gain of $151 thousand and net unrealized loss of $156 thousand for the same periods in September 30, 2016.

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 September 30, 2017, December 31, 2016, and September 30, 2016 are summarized by type as follows: September 30, 2017 December 31, 2016 September 30, 2016 (dollars in thousands) Amount % Amount % Amount % Commercial $ 1,244,184 20 % $ 1,200,728 21 % $ 1,130,042 21 % Income producing - commercial real estate 2,898,948 48 % 2,509,517 44 % 2,551,186 46 % Owner occupied - commercial real estate 749,580 12 % 640,870 12 % 590,427 11 % Real estate mortgage - residential 109,460 2 % 152,748 3 % 154,439 3 % Construction - commercial and residential* 915,493 15 % 932,531 16 % 838,137 15 % Construction - C&I (owner occupied) 55,828 1 % 126,038 2 % 104,676 2 % Home equity 101,898 2 % 105,096 2 % 106,856 2 % Other consumer 8,813 — 10,365 — 6,212 — Total loans 6,084,204 100 % 5,677,893 100 % 5,481,975 100 % Less: allowance for credit losses (62,967 ) (59,074 ) (56,864 ) Net loans $ 6,021,237 $ 5,618,819 $ 5,425,111 *Includes land loans. Unamortized net deferred fees amounted to $23.3 million, $22.3 million, and $20.9 million at September 30, 2017, December 31, 2016, and September 30, 2016, respectively. As of September 30, 2017 and December 31, 2016, the Bank serviced $176.5 million and $128.8 million, respectively, of 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 September 30, 2017, owner occupied - commercial real estate and construction - C&I (owner occupied) represent approximately 13% of the loan portfolio. At September 30, 2017, non-owner occupied commercial real estate and real estate construction represented approximately 63% of the loan portfolio. The combined owner occupied and commercial real estate loans represent approximately 76% 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 20% of the loan portfolio at September 30, 2017 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. Approximately 2% of the loan portfolio at September 30, 2017 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 15 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. 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. 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 $1.44 billion at September 30, 2017. A portion of the ADC portfolio, both speculative and non-speculative, includes loan funded interest reserves at origination. ADC loans are serviced by loan funded interest reserves and represent approximately 79% of the outstanding ADC loan portfolio at September 30, 2017. 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. From time to time the Company may make loans for its own portfolio or through its higher risk loan affiliate, ECV. Such loans, which are made to finance projects (which may also be financed at the Bank level), may have higher risk characteristics than loans made by the Bank, such as lower priority interests and/or higher loan to value ratios. The Company seeks an overall financial return on these transactions commensurate with the risks and structure of each individual loan. Certain transactions may bear current interest at a rate with a significant premium to normal market rates. Other loan transactions may carry a standard rate of current interest, but also earn additional interest based on a percentage of the profits of the underlying project or a fixed accrued rate of interest. Allowance for Credit Losses The following tables detail activity in the allowance for credit losses by portfolio segment for the three and nine months ended September 30, 2017 and 2016. 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 September 30, 2017, December 31, 2016 and September 30, 2016.

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 September 30, 2017, December 31, 2016 and September 30, 2016.

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 September 30, 2017, December 31, 2016 and September 30, 2016.

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 September 30, 2017, 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.

During the nine months of 2017, there was one default on a $237 thousand restructured loan which was charged off, as compared to the same period in 2016, which had one default on a $5.0 million 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 were two nonperforming TDRs totaling $588 thousand reclassified to nonperforming loans during the nine months ended September 30, 2017. There was one nonperforming TDR totaling $5.0 million reclassified to nonperforming loans during the nine months ended September 30, 2016. 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 i

Interest Rate Swap Derivatives

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 September 30, 2017, 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 $167 thousand at September 30, 2017 compared to a net unrealized loss before income tax of $692 thousand at December 31, 2016. The net unrealized gain at September 30, 2017 compared to the net unrealized loss at December 31, 2016 is due to the increase in current market expectation of short term interest rates for the remaining term of the designated cash flow hedge interest rate swap. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is initially reported in other comprehensive income (outside of earnings), net of tax, and subsequently reclassified to earnings when the hedged transaction affects earnings, and the ineffective portion of changes in the fair value of the derivative is recognized directly in 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. The Company recognized an immaterial amount in earnings due to hedge ineffectiveness during both the nine month periods ended September 30, 2017 and September 30, 2016. 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 September 30, 2017, the Company reclassified $307 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 $657 thousand will be reclassified as an increase 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/adequately 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 September 30, 2017, 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) were in a net asset position of $167 thousand (none of these contracts were in a net liability position as of September 30, 2017). As of September 30, 2017, the Company has minimum collateral posting thresholds with certain of its derivative counterparties and has posted collateral of $890 thousand against its obligations under these agreements. If the Company had breached any provisions under the agreements at September 30, 2017, 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 September 30, 2017 and December 31, 2016.

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 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. 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. In February 2017, the Company awarded 91,097 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 2017, the Company awarded senior officers a targeted number of 36,523 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 three performance metrics: 1) average annual earnings per share growth; 2) average annual total shareholder return; and 3) 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 227,324 shares at September 30, 2017. Unrecognized stock based compensation expense related to restricted stock awards totaled $9.3 million at September 30, 2017. At such date, the weighted-average period over which this unrecognized expense was expected to be recognized was 2.13 years.

The total fair value of stock options vested was $50 thousand and $45 thousand for the nine months ended September 30, 2017 and 2016, respectively. Unrecognized stock-based compensation expense related to stock options totaled $90 thousand at September 30, 2017. At such date, the weighted-average period over which this unrecognized expense was expected to be recognized was 2.09 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 September 30, 2017, the 2011 ESPP had 406,081 shares remaining for issuance. Included in salaries and employee benefits in the accompanying Consolidated Statements of Operations, the Company recognized $4.2 million and $5.2 million in stock-based compensation expense for the nine months ended September 30, 2017 and 2016, 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. Assets and Liabilities Recorded at Fair Value on a Recurring Basis The table below presents the recorded amount of assets and liabilities measured at fair value on a recurring basis as of September 30, 2017 and December 31, 2016. (dollars in thousands) Quoted Prices Significant Other Significant Other Total September 30, 2017 Assets: Investment securities available for sale: U. S. agency securities $ — $ 177,918 $ — $ 177,918 Residential mortgage backed securities — 301,526 — 301,526 Municipal bonds — 63,147 — 63,147 Corporate bonds — 11,717 1,500 13,217 Other equity investments — — 218 218 Loans held for sale — 25,980 — 25,980 Mortgage banking derivatives — — 63 63 Interest rate swap derivatives — 191 — 191 Total assets measured at fair value on a recurring basis as of September 30, 2017 $ — $ 580,479 $ 1,781 $ 582,260 Liabilities: Mortgage banking derivatives $ — $ — $ 36 $ 36 Interest rate swap derivatives — 24 — 24 Total liabilities measured at fair value on a recurring basis as of September 30, 2017 $ — $ 24 $ 36 $ 60 December 31, 2016 Assets: Investment securities available for sale: U.

Fair value measurement is based upon quoted prices, if available. 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. Level 1 securities include those traded on an active exchange such as the New York Stock Exchange, Treasury securities that are traded by dealers or brokers in active over-the-counter markets and money market funds. Level 2 securities include U.S. agency debt securities, mortgage backed securities issued by Government Sponsored Entities (“GSE’s”) and municipal bonds. Securities classified as Level 3 include securities in less liquid markets, the carrying amounts approximate the fair value. Loans held for sale The following table summarizes the difference between the aggregate fair value and the aggregate unpaid principal balance for residential real estate loans held for sale measured at fair value as of September 30, 2017 and December 31, 2016.

Assets and Liabilities Recorded at Fair Value on a Nonrecurring Basis The Company measures certain assets at fair value on a nonrecurring basis and the following is a general description of the methods used to value such assets. Impaired loans Other real estate owned (dollars in thousands) Quoted Prices Significant Other Significant Other Total September 30, 2017 Impaired loans: Commercial $ — $ — $ 2,757 $ 2,757 Income producing - commercial real estate — — 8,714 8,714 Owner occupied - commercial real estate — — 5,885 5,885 Real estate mortgage - residential — — 301 301 Construction - commercial and residential — — 2,030 2,030 Home equity — — 504 504 Other consumer — — 11 11 Other real estate owned — — 1,394 1,394 Total assets measured at fair value on a nonrecurring basis as of September 30, 2017 $ — $ — $ 21,596 $ 21,596 (dollars in thousands) Quoted Prices Significant Other Significant Other Total December 31, 2016 Impaired loans: Commercial $ — $ — $ 2,956 $ 2,956 Income producing - commercial real estate — — 12,993 12,993 Owner occupied - commercial real estate — — 2,133 2,133 Real estate mortgage - residential — — 555 555 Construction - commercial and residential — — 1,550 1,550 Other consumer — — 13 13 Other real estate owned — — 2,694 2,694 Total assets measured at fair value on a nonrecurring basis as of December 31, 2016 $ — $ — $ 22,894 $ 22,894 Loans The Company does not record loans at fair value on a recurring basis; however, from time to time, a loan is considered impaired and an allowance for loan loss is established. Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan are considered impaired. Once a loan is identified as individually impaired, management measures impairment in accordance with ASC Topic 310, “Receivables.” Fair Value of Financial Instruments The Company discloses fair value information about financial instruments for which it is practicable to estimate the value, whether or not such financial instruments are recognized on the balance sheet. 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 September 30, 2017 and December 31, 2016 are as follows: Fair Value Measurements Quoted Prices in Significant Other Significant (dollars in thousands) Carrying Value Fair Value (Level 1) (Level 2) (Level 3) September 30, 2017 Assets Cash and due from banks $ 8,246 $ 8,246 $ — $ 8,246 $ — Federal funds sold 8,548 8,548 — 8,548 — Interest bearing deposits with other banks 432,156 432,156 — 432,156 — Investment securities 556,026 556,026 — 554,308 1,718 Federal Reserve and Federal Home Loan Bank stock 30,980 30,980 — 30,980 — Loans held for sale 25,980 25,980 — 25,980 — Loans, net 6,021,237 6,075,997 — — 6,075,997 Bank owned life insurance 61,238 61,238 — 61,238 — Annuity investment 11,591 11,591 — 11,591 — Mortgage banking derivatives 63 63 — — 63 Interst rate swap derivatives 191 191 — 191 — Liabilities Noninterest bearing deposits 1,843,157 1,843,157 — 1,843,157 — Interest bearing deposits 3,248,118 3,248,118 — 3,248,118 — Certificates of deposit 822,677 821,892 — 821,892 — Customer repurchase agreements 73,569 73,569 — 73,569 — Borrowings 416,807 448,768 — 448,768 — Mortgage banking derivatives 36 36 — — 36 Interest rate swap derivatives 24 24 — 24 — December 31, 2016 Assets Cash and due from banks $ 10,285 $ 10,285 $ — $ 10,285 $ — Federal funds sold 2,397 2,397 — 2,397 — Interest bearing deposits with other banks 355,481 355,481 — 355,481 — Investment securities 538,108 538,108 — 536,390 1,718 Federal Reserve and Federal Home Loan Bank stock 21,600 21,600 — 21,600 — Loans held for sale 51,629 51,629 — 51,629 — Loans, net 5,618,819 5,624,084 — — 5,624,084 Bank owned life insurance 60,130 60,130 — 60,130 — Annuity investment 11,929 11,929 — 11,929 — Mortgage banking derivatives 114 114 — — 114 Liabilities Noninterest bearing deposits 1,775,684 1,775,684 — 1,775,684 — Interest bearing deposits 3,191,682 3,191,682 — 3,191,682 — Certificates of deposit 748,748 745,985 — 745,985 — Customer repurchase agreements 68,876 68,876 — 68,876 — Borrowings 216,514 203,657 — 203,657 — Mortgage banking derivatives 55 55 — — 55 Interest rate swap derivatives 692 692 — 692 —

Supplemental Executive Retireme

Supplemental Executive Retirement Plan	9 Months Ended

Retirement Benefits [Abstract]
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 in 2013 carriers 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 September 30, 2017, the annuity contracts accrued $54 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 $11.6 million at September 30, 2017 and is included in other assets on the Consolidated Balance Sheet. For the three and nine months ended September 30, 2017, the Company recorded benefit expense accruals of $103 thousand and $308 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)	9 Months Ended
	Sep. 30, 2017
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, 2016 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, 2016. 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, 2016. Operating results for the three and nine months ended September 30, 2017 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	Nature of Operations The Company, through the Bank, conducts a full service community banking business, primarily in the metropolitan Washington, D.C area. 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 FHA loans. The Bank offers its products and services through twenty-one 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, provides subordinated financing for the acquisition, development and construction of real estate projects; these transactions involve higher levels of risk, together with commensurate higher returns. Refer to Higher Risk Lending – Revenue Recognition below.
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.
Cash Flows	Cash Flows For purposes of reporting cash flows, cash and cash equivalents include cash and due from banks, federal funds sold, and interest bearing deposits with other banks which have an original maturity of three months or less.
Investment Securities	Investment Securities The Company has no securities classified as trading, or as held to maturity. Securities available-for-sale are acquired as part of the Company’s asset/liability management strategy and may be sold in response to changes in interest rates, current market conditions, loan demand, changes in prepayment risk and other factors. Securities available-for-sale are carried at fair value, with unrealized gains or losses being reported as accumulated other comprehensive income/(loss), a separate component of shareholders’ equity, net of deferred income tax. Realized gains and losses, using the specific identification method, are included as a separate component of noninterest income in the Consolidated Statements of Operations. Premiums and discounts on investment securities are amortized/accreted to the earlier of call or maturity based on expected lives, which lives are adjusted based on prepayment assumptions and call optionality if any. Declines in the fair value of individual available-for-sale securities below their cost that are other-than-temporary in nature result in write-downs of the individual securities to their fair value. Factors affecting the determination of whether other-than-temporary impairment has occurred include a downgrading of the security by a rating agency, a significant deterioration in the financial condition of the issuer, or a change in management’s intent and ability to hold a security for a period of time sufficient to allow for any anticipated recovery in fair value. Management systematically evaluates investment securities for other-than-temporary declines in fair value on a quarterly basis. This analysis requires management to consider various factors, which include the: (1) duration and magnitude of the decline in value; (2) financial condition of the issuer or issuers; and (3) structure of the security. The entire amount of an impairment loss is recognized in earnings only when: (1) the Company intends to sell the security; or (2) it is more likely than not that the Company will have to sell the security before recovery of its amortized cost basis; or (3) the Company does not expect to recover the entire amortized cost basis of the security. In all other situations, only the portion of the impairment loss representing the credit loss must be recognized in earnings, with the remaining portion being recognized in shareholders’ equity as comprehensive income, net of deferred taxes.
Loans Held for Sale	Loans Held for Sale The Company regularly engages in sales of residential mortgage loans held for sale and the guaranteed portion of small business loans, guaranteed by the Small Business Administration (“SBA”), and originated by the Bank. The Company has elected to carry loans held for sale at fair value. Fair value is derived from secondary market quotations for similar instruments. Gains and losses on sales of these loans are recorded as a component of noninterest income in the Consolidated Statements of Operations. The Company’s current practice is to sell residential mortgage loans held for sale on a servicing released basis, and, therefore, it has no intangible asset recorded in the normal course of business for the value of such servicing as of September 30, 2017, December 31, 2016 and September 30, 2016. The sale of the guaranteed portion of SBA loans on a servicing retained basis, in a transaction apart from the loan’s origination, gives rise to an excess servicing asset, which is computed on a loan by loan basis with the unamortized amount being included in intangible assets in the Consolidated Balance Sheets. This excess servicing asset is being amortized on a straight-line basis (with adjustment for prepayments) as an offset to servicing fees collected and is included in other income in the Consolidated Statements of Operations. The Company enters into commitments to originate residential mortgage loans whereby the interest rate on the loan is determined prior to funding (i.e. interest rate lock commitments). Such interest rate lock commitments on mortgage loans to be sold in the secondary market are considered to be derivatives. To protect against the price risk inherent in residential mortgage loan commitments, the Company utilizes both “best efforts” and “mandatory delivery” forward loan sale commitments to mitigate the risk of potential decreases in the values of loans that would result from the exercise of the derivative loan commitments. Under a “best efforts” contract, the Company commits to deliver an individual mortgage loan of a specified principal amount and quality to an investor and the investor commits to a price that it will purchase the loan from the Company if the loan to the underlying borrower closes. The Company protects itself from changes in interest rates through the use of best efforts forward delivery commitments, whereby the investor commits to purchase a loan at a price representing a premium on the day the borrower commits to an interest rate with the intent that the buyer/investor has assumed the interest rate risk on the loan. As a result, the Bank is not generally exposed to losses on loans sold utilizing best efforts, nor will it realize gains related to rate lock commitments due to changes in interest rates. The market values of interest rate lock commitments and best efforts contracts are not readily ascertainable with precision because rate lock commitments and best efforts contracts are not actively traded. Because of the high correlation between rate lock commitments and best efforts contracts, no gain or loss should occur on the interest rate lock commitments. Under a “mandatory delivery” contract, the Company commits to deliver a certain principal amount of mortgage loans to an investor at a specified price on or before a specified date. If the Company fails to deliver the amount of mortgages necessary to fulfill the commitment by the specified date, it is obligated to pay the investor a “pair-off” fee, based on then-current market prices, to compensate the investor for the shortfall. The Company manages the interest rate risk on interest rate lock commitments by entering into forward sale contracts of mortgage backed securities, whereby the Company obtains the right to deliver securities to investors in the future at a specified price. Such contracts are accounted for as derivatives and are recorded at fair value in derivative assets or liabilities, carried on the Consolidated Balance Sheet within other assets or other liabilities with changes in fair value recorded in other income within the Consolidated Statements of Operations. The period of time between issuance of a loan commitment to the customer and closing and sale of the loan to an investor generally ranges from 30 to 90 days under current market conditions. The gross gains on loan sales are recognized based on new loan commitments with adjustment for price and pair-off activity. Commission expenses on loans held for sale are recognized based on loans closed. In circumstances where the Company does not deliver the whole loan to an investor, but rather elects to retain the loan in its portfolio, the loan is transferred from held for sale to loans at fair value at date of transfer. The Company originates a small number of FHA loans through the Department of Housing and Urban Development’s Multifamily Accelerated Program (“MAP”). The Company securitizes these loans through the Government National Mortgage Association (“Ginnie Mae”) MBS I program and sells the resulting securities in the open market to authorized dealers in the normal course of business and generally retains the servicing rights. When servicing is retained on FHA loans securitized and sold, the Company computes an excess servicing asset on a loan by loan basis with the unamortized amount being included in intangible assets in the Consolidated Balance Sheets. Revenue represents gains from the sale of the Ginnie Mae securities and net revenues earned on the servicing of FHA loans securitizing the Ginnie Mae securities. The gains on Ginnie Mae securities include the realized and unrealized gains and losses on sales of FHA mortgage loans, as well as the changes in fair value of FHA interest rate lock commitments and FHA forward loan sale commitments. Revenue from servicing commercial FHA mortgages is recognized as earned based on the specific contractual terms of the underlying servicing agreements, along with amortization of and changes in impairment of mortgage servicing rights.
Loans	Loans Loans are stated at the principal amount outstanding, net of unamortized deferred costs and fees. Interest income on loans is accrued at the contractual rate on the principal amount outstanding. It is the Company’s policy to discontinue the accrual of interest when circumstances indicate that collection is doubtful. Deferred fees and costs are being amortized on the interest method over the term of the loan. Management considers loans impaired when, based on current information, it is probable that the Company will not collect all principal and interest payments according to contractual terms. Loans are evaluated for impairment in accordance with the Company’s portfolio monitoring and ongoing risk assessment procedures. Management considers the financial condition of the borrower, cash flow of the borrower, payment status of the loan, and the value of the collateral, if any, securing the loan. Generally, impaired loans do not include large groups of smaller balance homogeneous loans such as residential real estate and consumer type loans which are evaluated collectively for impairment and are generally placed on nonaccrual when the loan becomes 90 days past due as to principal or interest. Loans specifically reviewed for impairment are not considered impaired during periods of “minimal delay” in payment (90 days or less) provided eventual collection of all amounts due is expected. The impairment of a loan is measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, or the fair value of the collateral if repayment is expected to be provided solely by the collateral. In appropriate circumstances, interest income on impaired loans may be recognized on a cash basis.
Higher Risk Lending - Revenue Recognition	Higher Risk Lending – Revenue Recognition The Company had occasionally made higher risk acquisition, development, and construction (“ADC”) loans that entailed higher risks than ADC loans made following normal underwriting practices (“higher risk loan transactions”). These higher risk loan transactions were made through the Company’s subsidiary, ECV. This activity was limited as to individual transaction amount and total exposure amounts, based on capital levels, and is carefully monitored. The loans are carried on the balance sheet at amounts outstanding. ECV had three higher risk loan transactions outstanding as of September 30, 2017 and December 31, 2016, amounting to $9.5 million and $9.3 million, respectively.
Allowance for Credit Losses	Allowance for Credit Losses The allowance for credit losses represents an amount which, in management’s judgment, is adequate to absorb probable losses on loans and other extensions of credit that may become uncollectible. The adequacy of the allowance for credit losses is determined through careful and continuous review and evaluation of the loan portfolio and involves the balancing of a number of factors to establish a prudent level of allowance. Among the factors considered in evaluating the adequacy of the allowance for credit losses are lending risks associated with growth and entry into new markets, loss allocations for specific credits, the level of the allowance to nonperforming loans, historical loss experience, economic conditions, portfolio trends and credit concentrations, changes in the size and character of the loan portfolio, and management’s judgment with respect to current and expected economic conditions and their impact on the existing loan portfolio. Allowances for impaired loans are generally determined based on collateral values. Loans or any portion thereof deemed uncollectible are charged against the allowance, while recoveries are credited to the allowance. Management adjusts the level of the allowance through the provision for credit losses, which is recorded as a current period operating expense. The allowance for credit losses consists of allocated and unallocated components. The components of the allowance for credit losses represent an estimation done pursuant to Accounting Standards Codification (“ASC”) Topic 450, “Contingencies,” “Receivables.” Management believes that the allowance for credit losses is adequate; however, determination of the allowance is inherently subjective and requires significant estimates. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic conditions. Evaluation of the potential effects of these factors on estimated losses involves a high degree of uncertainty, including the strength and timing of economic cycles and concerns over the effects of a prolonged economic downturn in the current cycle. In addition, various banking agencies, as an integral part of their examination process, and independent consultants engaged by the Bank, periodically review the Bank’s loan portfolio and allowance for credit losses. Such review may result in recognition of additions to the allowance based on their judgments of information available to them at the time of their examination.
Premises and Equipment	Premises and Equipment Premises and equipment are stated at cost less accumulated depreciation and amortization computed using the straight-line method for financial reporting purposes. Premises and equipment are depreciated over the useful lives of the assets, which generally range from three to seven years for furniture, fixtures and equipment, three to five years for computer software and hardware, and five to twenty years for building improvements. Leasehold improvements are amortized over the terms of the respective leases, which may include renewal options where management has the positive intent to exercise such options, or the estimated useful lives of the improvements, whichever is shorter. The costs of major renewals and betterments are capitalized, while the costs of ordinary maintenance and repairs are expensed as incurred. These costs are included as a component of premises and equipment expenses on the Consolidated Statements of Operations.
Other Real Estate Owned (OREO)	Other Real Estate Owned (OREO) Assets acquired through loan foreclosure are held for sale and are recorded at fair value less estimated selling costs when acquired, establishing a new cost basis. The new basis is supported by appraisals that are generally no more than twelve months old. Costs after acquisition are generally expensed. If the fair value of the asset declines, a write-down is recorded through noninterest expense. The valuation of foreclosed assets is subjective in nature and may be adjusted in the future because of changes in market conditions or appraised values.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Other intangible assets represent purchased assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights. Intangible assets that have finite lives, such as core deposit intangibles, are amortized over their estimated useful lives and subject to periodic impairment testing. Intangible assets (other than goodwill) are amortized to expense using accelerated or straight-line methods over their respective estimated useful lives. Goodwill is subject to impairment testing at the reporting unit level, which must be conducted at least annually. The Company performs impairment testing during the fourth quarter of each year or when events or changes in circumstances indicate the assets might be impaired. The Company performs a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing updated qualitative factors, the Company determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, it does not have to perform the two-step goodwill impairment test. Determining the fair value of a reporting unit under the first step of the goodwill impairment test and determining the fair value of individual assets and liabilities of a reporting unit under the second step of the goodwill impairment test are judgmental and often involve the use of significant estimates and assumptions. Similarly, estimates and assumptions are used in determining the fair value of other intangible assets. Estimates of fair value are primarily determined using discounted cash flows, market comparisons and recent transactions. These approaches use significant estimates and assumptions including projected future cash flows, discount rates reflecting the market rate of return, projected growth rates and determination and evaluation of appropriate market comparables. Based on the results of qualitative assessments of all reporting units, the Company concluded that no impairment existed at December 31, 2016. However, future events could cause the Company to conclude that goodwill or other intangibles have become impaired, which would result in recording an impairment loss. Any resulting impairment loss could have a material adverse impact on the Company’s financial condition and results of operations.
Interest Rate Swap Derivatives	Interest Rate Swap Derivatives The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities and through the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments designated as cash flow hedges are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to certain variable rate deposits. Refer to the “Loans Held for Sale” section for a discussion on forward commitment contracts, which are also considered derivatives. At the inception of a derivative contract, the Company designates the derivative as one of three types based on the Company’s intentions and belief as to likely effectiveness as a hedge. These three types are (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (“fair value hedge”), (2) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedge”), or (3) an instrument with no hedging designation (“stand-alone derivative”). Regarding Interest Rate Swap Derivatives, the Company has no fair value hedges, only cash flow hedges. For a cash flow hedge, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same period(s) during which the hedged transaction affects earnings (i.e. the period when cash flows are exchanged between counterparties). For both fair value and cash flow hedges, changes in the fair value of derivatives that are not highly effective in hedging the changes in fair value or expected cash flows of the hedged item are recognized immediately in current earnings. Changes in the fair value of derivatives that do not qualify for hedge accounting are reported currently in earnings, as noninterest income. Net cash settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in noninterest income. Cash flows on hedges are classified in the cash flow statement the same as the cash flows of the items being hedged. The Company formally documents the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions at the inception of the hedging relationship. This documentation includes linking fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used are highly effective in offsetting changes in fair values or cash flows of the hedged items. The Company discontinues hedge accounting when it determines that the derivative is no longer highly effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm, or treatment of the derivative as a hedge is no longer appropriate or intended. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as noninterest income or expense. When a fair value hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted over the remaining life of the asset or liability. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that were accumulated in other comprehensive income are amortized into earnings over the same periods in which the hedged transactions will affect earnings.
Customer Repurchase Agreements	Customer Repurchase Agreements The Company enters into agreements under which it sells securities subject to an obligation to repurchase the same securities. Under these arrangements, the Company may transfer legal control over the assets but still retain effective control through an agreement that both entitles and obligates the Company to repurchase the assets. As a result, securities sold under agreements to repurchase are accounted for as collateralized financing arrangements and not as a sale and subsequent repurchase of securities. The agreements are entered into primarily as accommodations for large commercial deposit customers. The obligation to repurchase the securities is reflected as a liability in the Company’s Consolidated Balance Sheets, while the securities underlying the securities sold under agreements to repurchase remain in the respective assets accounts and are delivered to and held as collateral by third party trustees.
Marketing and Advertising	Marketing and Advertising Marketing and advertising costs are generally expensed as incurred.
Income Taxes	Income Taxes The Company employs the asset and liability method of accounting for income taxes as required by ASC Topic 740, “ Income Taxes
Transfer of Financial Assets	Transfer of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. In certain cases, the recourse to the Bank to repurchase assets may exist but is deemed immaterial based on the specific facts and circumstances.
Earnings per Common Share	Earnings per Common Share Basic net income per common share is derived by dividing net income by the weighted-average number of common shares outstanding during the period measured. Diluted earnings per common share is computed by dividing net income by the weighted-average number of common shares outstanding during the period measured including the potential dilutive effects of common stock equivalents.
