Note 1 - Summary of Significant Accounting Policies	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Note 1 – Summary of Significant Accounting Policies
	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 investment in subsidiaries is recorded on the Company’s books (Parent Only) on the basis of its equity in the net assets of the subsidiary. The accounting and reporting policies of the Company conform to generally accepted accounting principles (“GAAP”) in the United States of America and to general practices in the banking industry. Certain reclassifications have been made to amounts previously reported to conform to the classification made in 2014. The following is a summary of the more significant accounting policies.
	Nature of Operations
	The Company, through the Bank, conducts a full service community banking business, primarily in Northern Virginia, Montgomery County, Maryland, and Washington, D.C. On October 31, 2014, the Company completed its acquisition of Virginia Heritage Bank (“Virginia Heritage”). Refer to Note 2 for a full description of this transaction. 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 and the origination of small business loans. The guaranteed portion of small business loans, guaranteed by the Small Business Administration (“SBA”), is typically sold to third party investors in a transaction apart from the loan’s origination. As of December 31, 2014, the Bank offers its products and services through twenty two 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.
	Business Combinations
	Business combinations are accounted for by applying the acquisition method in accordance with Accounting Standards Codification (“ASC”) 805, Business Combinations. Under the acquisition method, identifiable assets acquired and liabilities assumed, and any non-controlling interest in the acquiree at the acquisition date are measured at their fair values as of that date, and are recognized separately from goodwill. Results of operations of the acquired entities are included in the consolidated statement of income from the date of acquisition.
	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.
	Loans Held for Sale
	The Company engages in sales of residential mortgage loans and the guaranteed portion of SBA loans originated by the Bank. Loans held for sale are carried at the lower of aggregate cost or 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 on a servicing released basis, and, therefore, it has no intangible asset recorded for the value of such servicing as of December 31, 2014 and December 31, 2013. The sale of the guaranteed portion of SBA loans on a servicing retained basis 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 statement 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. rate lock commitments). Such 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 decrease 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 Company 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 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 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 rate lock commitments on mortgage loans to be sold in the secondary market are considered to be derivatives the Company manages the interest rate risk on 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, with changes in fair value recorded in other income. 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.
	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 at fair value.
	Investment Securities
	The Company has no securities classified as trading, nor are any investment securities classified as held to maturity. Marketable equity securities and debt securities not classified as held to maturity or trading are classified as available-for-sale. 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 prepayments and call optionality. 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: (1) duration and magnitude of the decline in value; (2) the 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 debt security; (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
	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 on loans 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 (ninety 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 the cash basis.
	Higher Risk Lending – Revenue Recognition
	The Company has occasionally made higher risk acquisition, development, and construction (“ADC”) loans that entail higher risks than ADC loans made following normal underwriting practices (“higher risk loan transactions”). These higher risk loan transactions are currently made through the Company’s subsidiary, ECV. This activity is 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 and meet the loan classification requirements of the Accounting Standard Executive Committee (“AcSEC”) guidance reprinted from the CPA Letter, Special Supplement, dated February 10, 1986 (also referred to as Exhibit 1 to AcSEC Practice Bulletin No. 1). Additional interest earned on these higher risk loan transactions (as defined in the individual loan agreements) is recognized as realized under the provisions contained in AcSEC’s guidance reprinted from the CPA Letter, Special Supplement, dated February 10, 1986 (also referred to as Exhibit 1 to AcSEC Practice Bulletin No.1) and Staff Accounting Bulletin No. 101 (Revenue Recognition in Financial Statements). Certain additional interest is included as a component of noninterest income.  ECV recorded no additional interest on higher risk transactions during 2014, 2013 or 2012 (although normal interest income was recorded) and had four higher risk lending transactions outstanding as of December 31, 2014, as compared to five higher risk lending transaction outstanding as of December 31, 2013, amounting to $6.2 million and $7.4 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 existing 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 ASC Topic 450, “Contingencies,” or ASC Topic 310, “Receivables.” Specific allowances are established in cases where management has identified significant conditions or circumstances related to a specific credit that management believes indicate the probability that a loss may be incurred. For potential problem credits for which specific allowance amounts have not been determined, the Company establishes allowances according to the application of credit risk factors. These factors are set by management and approved by the appropriate Board committee to reflect its assessment of the relative level of risk inherent in each risk grade. A third component of the allowance computation, termed a nonspecific or environmental factors allowance, is based upon management’s evaluation of various environmental conditions that are not directly measured in the determination of either the specific allowance or formula allowance. Such conditions include general economic and business conditions affecting key lending areas, credit quality trends (including trends in delinquencies and nonperforming loans expected to result from existing conditions), loan volumes and concentrations, specific industry conditions within portfolio categories, recent loss experience in particular loan categories, duration of the current business cycle, bank regulatory examination results, findings of outside review consultants, and management’s judgment with respect to various other conditions including credit administration and management and the quality of risk identification systems. Executive management reviews these environmental conditions quarterly, and documents the rationale for all changes.
	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 regulatory 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 seven years for furniture, fixtures and equipment, three to five years for computer software and hardware, and ten to forty years for buildings and 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 initially recorded at fair value less estimated selling costs when acquired, establishing a new cost basis. The new basis is supported by recent appraisals. 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 and other intangibles are 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 quantitative assessments of all reporting units, the Company concluded that no impairment existed at December 31, 2014. 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.
	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 liability method of accounting for income taxes as required by ASC Topic 740, “Income Taxes.” Under the liability method, deferred-tax assets and liabilities are determined based on differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities (i.e., temporary timing differences) and are measured at the enacted rates that will be in effect when these differences reverse. The Company utilizes statutory requirements for its income tax accounting, and avoids risks associated with potentially problematic tax positions that may incur challenge upon audit, where an adverse outcome is more likely than not. Therefore, no provisions are made in the Company’s tax reserves for uncertain tax positions or accompanying potential tax penalties and interest for underpayments of income taxes. In accordance with ASC Topic 740, the Company may establish a reserve against deferred tax assets in those cases where realization is less than certain, although no such reserves exist at either December 31, 2014 or December 31, 2013.
	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 obtain 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 be 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 available to common shareholders by the weighted-average number of common shares outstanding during the period measured. Diluted earnings per common share is computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding during the period measured including the potential dilutive effects of common stock equivalents. Earnings per share amounts for periods ending prior to June 30, 2013 have been adjusted to reflect a 10% stock dividend paid on June 14, 2013.
	Stock-Based Compensation
	In accordance with ASC Topic 718, “Compensation,” the Company records as compensation expense an amount equal to the amortization (over the remaining service period) of the fair value (computed at the date of option grant) of any outstanding fixed stock option grant and restricted stock award. Compensation expense on variable stock option grants (i.e. performance based grants) if any, is recorded based on the probability of achievement of the goals underlying the performance grant. Refer to Note 13 for a description of stock-based compensation awards, activity and expense for the years ended December 31, 2014, 2013 and 2012.
	New Authoritative Accounting Guidance
	In January 2014, the FASB issued ASU No. 2014-01, "Accounting for Investments in Qualified Affordable Housing Projects." ASU No. 2014-01 permits reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognize the net investment performance in the income statement as a component of income tax expense. This new guidance also requires new disclosures for all investors in these projects. ASU No. 2014-01 is effective for interim and annual reporting periods beginning after December 15, 2014. Upon adoption, the guidance must be applied retrospectively to all periods presented. However, entities that use the effective yield method to account for investments in these projects before adoption may continue to do so for these pre-existing investments. The Company currently accounts for such investments using the effective yield method and plans to continue to do so for these pre-existing investments after adopting ASU No. 2014-01 on January 1, 2015. The Company expects investments made after January 1, 2015 to meet the criteria required for the proportional amortization method and plans to make such an accounting policy election. The adoption of ASU No. 2014-01 is not expected to have a material impact on the Company's consolidated financial statements.
	In January 2014, the FASB issued ASU No. 2014-04, "Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure." The objective of this guidance is to clarify when an in substance repossession or foreclosure occurs, that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be derecognized and the real estate property recognized. ASU No. 2014-04 states that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, ASU No. 2014-04 requires interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. ASU No. 2014-04 is effective for interim and annual reporting periods beginning after December 15, 2014. The adoption of ASU No. 2014-04 is not expected to have a material impact on the Company's consolidated financial statements.

Business Combination Disclosure [Text Block]	Note 2 – Mergers and Acquisitions
	On October 31, 2014, the Company completed its acquisition of Virginia Heritage, a banking institution based in FairFax County, Virginia. The acquisition of Virginia Heritage was effected through the merger (the “Merger”) of Virginia Heritage with and into EagleBank, in accordance with the Agreement and Plan of Reorganization (the “Merger Agreement”) among the Company, EagleBank and Virginia Heritage, dated June 9, 2014. Pursuant to the Merger Agreement, each share of Virginia Heritage common stock was converted into the right to receive 0.6632 shares of Company common stock and $7.50 in cash, plus cash in lieu of fractional shares. Outstanding options to acquire Virginia Heritage common stock were converted into fully vested options to purchase an aggregate of 401,497 shares of Company common stock. In connection with the Merger, the Company paid an aggregate of $45.4 million in cash to former shareholders of Virginia Heritage and issued 4,010,261 shares of Company common stock were issued. On the acquisition date, the estimated fair values of Virginia Heritage included $914 million in assets, $800 million in loans and $645 million in deposits. The acquisition was valued at $189 million Additionally, pursuant to the Merger Agreement, each of the 15,300 shares of Virginia Heritage’s Senior Non-Cumulative Perpetual Preferred Stock, Series A, $1,000 liquidation amount per share (“Virginia Heritage Series A Preferred Stock”), which was issued to the U.S. Treasury pursuant to the Small Business Lending Fund Program (“SBLF”), was exchanged for one share of a new series of the Company’s Senior Non-Cumulative Perpetual Preferred Stock, Series C, liquidation amount $1,000 per share (the “Series C Preferred Stock”), which ranks equally with and has substantially identical terms and conditions as the Company’s existing Senior Non-Cumulative Perpetual Preferred Stock, Series B, liquidation amount $1,000 per share (“Series B Preferred Stock”). The Series C Preferred Stock has a dividend rate of 1.00%. The assets acquired and liabilities assumed were accounted for under the acquisition method of accounting. The assets and liabilities, both tangible and intangible, were recorded at their fair value as of October 31, 2014, based on management’s best estimates using the information available as of the merger date. The Company incurred $4.7 million of acquisition related expenses during the year ended December 31, 2014 related to the acquisition of Virginia Heritage, included within “Merger expenses” in the Consolidated Statements of Operations.
	Virginia Heritage’s results of operations have been included in the Company’s consolidated statements of income and comprehensive income for the two months ended December 31, 2014. Based on a purchase price allocation, the Company recorded $102.3 million in goodwill and $4.6 million in core deposit intangibles as a result of the acquisition. These fair value estimates are provisional amounts, include third party valuations, and will continue to be reviewed by the Company. Goodwill is not amortized for book purposes; however, it is reviewed at least annually for impairment, and is not deductible for tax purposes.
	Except for collateral dependent loans, the fair values for loans acquired from Virginia Heritage were estimated using cash flow projections based on the remaining maturity and repricing terms. Cash flows were adjusted by estimating future credit losses and the rate of prepayments. Projected monthly cash flows were then discounted to present value using a risk-adjusted market rate for similar loans. For collateral dependent loans with deteriorated credit quality, fair value was estimated by analyzing the value of the underlying collateral, assuming the fair values of the loans were derived from the eventual sale of the collateral. These values were discounted using market derived rates of return, with consideration given to the period of time and costs associated with the foreclosure and disposition of the collateral.
	The acquired loan portfolio subject to purchased credit impairment accounting guidance (ASC 310-30) as well as those excluded from ASC 310-30 accounting as of October 31, 2014 is as follows:
	(dollars in thousands)
	Accounted for under ASC 310-30:
	Contractual principal balance at acquisition	$	4,448

	Fair value discount		11,618
	Fair value at acquisition		801,063
	Total fair value at acquisition	$	804,320
	The core deposit intangible asset recognized is being amortized on an accelerated basis over the estimated life, currently expected to be 6 years.
	Goodwill is not amortized for book purposes; however, it is reviewed at least annually for impairment and is not deductible for tax purposes.
	The fair value of premises and equipment and other real estate owned was estimated using appraisals of like kind properties and assets. Premises, equipment and leasehold improvements will be amortized or depreciated over their estimated useful lives ranging from one to five years for equipment or over the life of the lease for leasehold improvements. Other real estate owned is not amortized and is carried at estimated fair value determined by the appraised value less costs to sell.
	The fair value of retail demand and interest bearing deposit accounts was assumed to approximate the carrying value as these accounts have no stated maturity and are payable on demand. The fair value of time deposits was estimated by discounting the contractual future cash flows using market rates offered for time deposits of similar remaining maturities. The fair value of borrowed funds was estimated by discounting the future cash flows using market rates for similar borrowings.
	The following unaudited pro forma financial information presents the consolidated results of operations of the Company and Virginia Heritage as if the acquisition had occurred as of January 1, 2013 with pro forma adjustments to give effect of any changes in interest income due to the accretion of the discount (premium) associated with the fair value adjustments to acquired loans, any changes in interest expenses due to estimated premium amortization/discount accretion associated with the fair value adjustment to acquired time deposits and the amortization of the core deposit intangible that would have resulted had the deposits been acquired as of January 1, 2013.

Cash and Cash Equivalents [Abstract]
Cash and Cash Equivalents Disclosure [Text Block]	Note 3 - Cash and Due from Banks
	Regulation D of the Federal Reserve Act requires that banks maintain reserve balances with the Federal Reserve Bank based principally on the type and amount of their deposits. During 2014, the Bank maintained balances at the Federal Reserve (in addition to vault cash) to meet the reserve requirements as well as balances to partially compensate for services. Late in 2008, the Federal Reserve in connection with the Emergency Economic Stabilization Act of 2008 began paying a nominal amount of interest on balances held, which interest on excess reserves was increased under provisions of the Dodd Frank Wall Street Reform and Consumer Protection Act passed in July 2010. Additionally, the Bank maintains interest-bearing balances with the Federal Home Loan Bank of Atlanta and noninterest bearing balances with seven domestic correspondent banks as compensation for services they provide to the Bank.

	Other equity investments		396		-		12		384
		$	383,665	$	4,003	$	9,535	$	378,133
	The unrealized losses that exist are generally the result of changes in market interest rates and interest spread relationships since original purchases. The weighted average duration of debt securities, which comprise 99.9% of total investment securities, is relatively short at 4.0 years. The gross unrealized gain on other equity investments represents common stock of one local banking company owned by the Company, and traded on a broker “bulletin board” exchange. The estimated fair value is determined by broker quoted prices. 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 December 31, 2014 represent an other-than-temporary impairment for the reasons noted. 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. In addition, at December 31, 2014, the Company held $22.6 million in equity securities in a combination of Federal Reserve Bank (“FRB”) and Federal Home Loan Bank (“FHLB”) stocks, which are held for regulatory purposes and are not marketable.
	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 as of December 31, 2014 and 2013 are as follows:

	Unamortized net deferred fees amounted to $15.6 million and $12.7 million at December 31, 2014 and 2013, of which $182 thousand and $235 thousand at December 31, 2014 and 2013, respectively, represented net deferred costs on home equity loans.
	Loans acquired from Virginia Heritage totaled $804 million at fair value, comprised of $801 million of loans that were not considered impaired at the acquisition date and $3.0 million of loans that were determined to be impaired at the time of acquisition. The impaired loans were accounted for in accordance with ASC Topic 310-30 “Accounting for Certain Loans or Debt Securities Acquired in a Transfer” (“ASC 310-30”). At December 31, 2014, the net recorded amount of loans accounted for under ASC 310-30 was $2.9 million. Loans acquired in the Merger that were determined to be purchased credit impaired loans were all considered collateral dependent loans. Therefore, estimated fair value calculations and projected cash flows included only return of principal and no interest income. There was no accretable yield associated with these loans during the year ended 2014.
	As of December 31, 2014 and 2013, the Bank serviced $67.9 million and $67.6 million, respectively, of 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 investment real estate. The combination of owner occupied commercial real estate and owner occupied commercial real estate construction represent 12% of the loan portfolio. At December 31, 2014, the combination of commercial real estate and real estate construction loans represent approximately 70% of the loan portfolio. When owner occupied commercial real estate and owner occupied commercial construction loans are excluded, the percentage of commercial real estate and construction loans to total loans decreases to 58%. 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 1.00. Personal guarantees are generally 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 cash flow, equipment and account receivable financing. This loan category represents approximately 21% of the loan portfolio at December 31, 2014 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 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 6% of the loan portfolio at December 31, 2014 consists of home equity loans and lines of credit and other consumer loans, consisting primarily of indirect automobile loans acquired in the Merger. These credits, while making up a smaller portion of the loan portfolio, demand the same emphasis on underwriting and credit evaluation as other types of loans advanced by the Bank.
	Approximately 3% of the loan portfolio consists of residential mortgage loans. These are typically loans underwritten to the same underwriting standards as residential loans held for sale but for shorter terms, generally less than 10 years.
	Loans are secured primarily by duly recorded first deeds of trust. In some cases, the Bank may accept a recorded junior trust position. In general, borrowers will have a proven ability to build, lease, manage and/or sell a commercial or residential project and demonstrate satisfactory financial condition. Additionally, an equity contribution toward the project is customarily required.
	Construction loans require that the financial condition and experience of the general contractor and major subcontractors be satisfactory to the Bank. Guaranteed, fixed price contracts are required whenever appropriate, along with payment and performance bonds or completion bonds for larger scale projects.
	Loans intended for residential land acquisition, lot development and construction are made on the premise that the land: 1) is or will be developed for building sites for residential structures, and; 2) will ultimately be utilized for construction or improvement of residential zoned real properties, including the creation of housing. Residential development and construction loans will finance projects such as single family subdivisions, planned unit developments, townhouses, and condominiums. Residential land acquisition, development and construction loans generally are underwritten with a maximum term of 36 months, including extensions approved at origination.
	Commercial land acquisition and construction loans are secured by real property where loan funds will be used to acquire land and to construct or improve appropriately zoned real property for the creation of income producing or owner user commercial properties. Borrowers are generally required to put equity into each project at levels determined by the appropriate Loan Committee. Commercial land acquisition and construction loans generally are underwritten with a maximum term of 24 months.
	Substantially all construction draw requests must be presented in writing on American Institute of Architects documents and certified either by the contractor, the borrower and/or the borrower’s architect. Each draw request shall also include the borrower’s soft cost breakdown certified by the borrower or its 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 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 1.00. 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 $851.5 million at December 31, 2014. A portion of the ADC portfolio, both speculative and non-speculative, includes loan funded interest reserves at origination. ADC loans containing loan funded interest reserves represent approximately 31% of the outstanding ADC loan portfolio at December 31, 2014. 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: (i) the feasibility of the project; (ii) the experience of the sponsor; (iii) the creditworthiness of the borrower and guarantors; (iv) borrower equity contribution; and (v) 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: (i) 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; (ii) a construction loan administration department independent of the lending function; (iii) third party independent construction loan inspection reports; (iv) 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 (v) 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.
	The following tables detail activity in the allowance for credit losses by portfolio segment for the years ended December 31, 2014 and 2013. Allocation of a portion of the allowance to one category of loans does not preclude its availability to absorb losses in other categories.

At December 31, 2014, the nonperforming loans acquired from Fidelity and Virginia Heritage have a carrying value of $529 thousand and $2.9 million, and an unpaid principal balance of $586 thousand and $4.0 million, and were evaluated separately in accordance with ASC Topic 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality.” The various impaired loans were recorded at estimated fair value with any excess being charged-off or treated as a non-accretable discount. Subsequent downward adjustments to the valuation of impaired loans acquired will result in additional loan loss provisions and related allowance for credit losses. Subsequent upward adjustments to the valuation of impaired loans acquired will result in accretable discount. No adjustments have been made to the fair value amounts of impaired loans subsequent to the allowable period of adjustment from the date of acquisition.
Credit Quality Indicators
The Company uses several credit quality indicators to manage credit risk in an ongoing manner. 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 - Loans inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the company will sustain some loss if the deficiencies are not corrected. Loss potential, while existing in the aggregate amount of substandard loans, does not have to exist in individual loans classified substandard.
	Classified (b) Doubtful - Loans that have all the weaknesses inherent in a loan classified substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. The possibility of loss is extremely high, but because of certain important and reasonably specific pending factors, which may work to the advantage and strengthening of the assets, its classification as an estimated loss is deferred until its more exact status may be determined.
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 December 31, 2014 and 2013.

Nonaccrual and Past Due Loans
Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Loans are placed on nonaccrual status when, in management’s opinion, the borrower may be unable to meet payment obligations as they become due, as well as when required by regulatory provisions. Loans may be placed on nonaccrual status regardless of whether or not such loans are considered past due. When interest accrual is discontinued, all unpaid accrued interest is reversed. 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.

Impaired Loans
Loans are considered impaired when, based on current information and events, it is probable the Company will be unable to collect all amounts due in accordance with the original contractual terms of the loan agreement, including scheduled principal and interest payments. 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.

Modifications
A modification of a loan constitutes a troubled debt restructuring (“TDR”) when a borrower is experiencing financial difficulty and the modification constitutes a concession. 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.
Loans modified in a TDR for the Company may have the financial effect of increasing the specific allowance associated with the loan. An allowance for impaired consumer and commercial loans that have been modified in a TDR is measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s observable market price, or the estimated fair value of the collateral, less any selling costs, if the loan is collateral dependent. Management exercises significant judgment in developing these estimates.
The following table presents by class, the recorded investment of loans modified in TDRs during the years ended December 31, 2014 and 2013.

During the year ended December 31, 2014, eight performing TDR loans totaling approximately $11.6 million experienced defaults on their modified terms. These eight previously performing TDRs were reclassified as follows; four nonperforming TDRs totaling $9.1 million were sold during the year, one nonperforming TDR totaling approximately $2.0 million was reclassified to OREO after the Company took possession of the underlying collateral, the Company was paid off on another TDR totaling $217 thousand, one to nonperforming loans totaling $227 thousand was reclassified to nonperforming loans, one TDR totaling $95 thousand was charged-off. A default is considered to have occurred once the TDR is past due 90 days or more, or it has been placed on nonaccrual. Commercial and consumer loans modified in a TDR are closely monitored for delinquency as an early indicator of possible future default. If loans modified in a TDR subsequently default, the Company evaluates the loan for possible further impairment. The allowance may be increased, adjustments may be made in the allocation of the allowance, or partial charge-offs may be taken to further write-down the carrying value of the loan. There were four loans totaling approximately $8.0 million modified in a TDR during the year ended December 31 2014, as compared to one loan totaling $1.2 million was modified during the year ended December 31, 2013.

Derivatives and Fair Value [Text Block]	Note 8 – Derivatives
	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 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 December 31, 2014 the Bank had derivative financial instruments with a notional value of $45.1 million related to its forward contracts. The fair value of these derivative instruments at December 31, 2014 were $146 thousand included in other assets and $250 thousand included in other liabilities. There were no derivative instruments in 2013.
	Included in other noninterest income for the year ended December 31, 2014 was a net gain of $140 thousand, relating to derivative instruments. The amount included in other noninterest income for year ended December 31, 2014 pertaining to its hedging activities was a net realized loss of $108 thousand. There were no derivative instruments or hedging activities in 2013.

	The Company offers its business customers a repurchase agreement sweep account in which it collateralizes these funds with U.S. Government agency and mortgage backed securities segregated in its investment portfolio for this purpose. By entering into the agreement, the customer agrees to have the Bank repurchase the designated securities on the business day following the initial transaction in consideration of the payment of interest at the rate prevailing on the day of the transaction.
	The Bank has commitments from correspondent banks under which it can purchase up to $137.5 million in federal funds on an unsecured basis, against which there were no amounts outstanding at December 31, 2014 and can borrow unsecured funds under one-way Certificates of Deposit Account Registry Service (“CDARS”) brokered deposits in the amount of $784.4 million, against which there was $14.3 million outstanding at December 31, 2014. The Bank has a commitment at December 31, 2014 from Promontory to place up to $300.0 million of brokered deposits from its Insured Network Deposit (“IND”) program with the Bank in amounts requested by the Bank, against which there was $246.9 million outstanding at December 31, 2014. At December 31, 2014, the Bank was also eligible to make advances from the FHLB up to $576.4 million based on collateral at the FHLB, of which $185.3 million was outstanding at December 31, 2014. The Bank may enter into repurchase agreements as well as obtain additional borrowing capabilities from the FHLB provided adequate collateral exists to secure these lending relationships. The Bank also has a back-up borrowing facility through the Discount Window at the Federal Reserve Bank of Richmond (“Federal Reserve Bank”). This facility, which amounts to approximately $409.0 million, is collateralized with specific loan assets identified to the Federal Reserve Bank. It is anticipated that, except for periodic testing, this facility would be utilized for contingency funding only.
	In December 2014, the Company renewed its Loan Agreement and related Stock Security Agreement and Promissory Note (the “credit facility”) with a regional bank, pursuant to which the Company may borrow, on a revolving basis, up to $50 million for working capital purposes, or to finance capital contributions to the Bank in whole and to ECV in part. This facility was originally entered into in August 2008 and has been renegotiated over the past six years to its current terms. The credit facility is secured by a first lien on a portion of the stock of the Bank, and bears interest at a floating rate equal to the Wall Street Journal Prime Rate minus 0.25% with a floor interest rate of 3.50%. Interest is payable on a monthly basis. The term of the credit facility expires on September 30, 2015. There were no amounts outstanding under this credit at December 31, 2014 or December 31, 2013.
	On September 3, 2013 the Company amended the terms of the $9.3 million of subordinated notes dated August 30, 2010. Under the amendment, the maturity date is extended from September 30, 2016 to September 30, 2021 and the interest rate is changed from 10%, to a fixed interest rate of 8.5% until August 30, 2016 and thereafter at a fixed rate of interest equal to the then current yield on the 5 year U.S. Treasury Note plus 7.03%. The notes are intended to qualify as Tier 2 capital for regulatory purposes to the fullest extent permitted under capital regulations applicable through December 31, 2014. The notes will not qualify for capital treatment upon implementation of recently adopted Basel III capital requirements. The payment of principal on the notes may only be accelerated upon the occurrence of certain bankruptcy or receivership related events relating to the Company or, to the extent permitted under capital rules to be adopted by the Federal Reserve Board pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act, a major bank subsidiary of the Company.
	Under capital rules in effect at December 31, 2014, the capital treatment of the notes must be phased out, at a rate of 20% of the original principal amount per year during the last five years of the term of the notes, commencing on October 1, 2016. Through December 31, 2014, $9.3 million of subordinated notes are includible as Tier 2 capital.
	On August 5, 2014, the Company completed the sale of $70.0 million of its 5.75% subordinated notes, due September 1, 2024 (the “Notes”). The Notes were offered to the public at par. The net proceeds were approximately $68.8 million, net of $1.2 million in deferred financing costs which will be amortized over the life of the Notes.

	On July 14, 2011, the Company entered into and consummated a Securities Purchase Agreement (the “Purchase Agreement”) with the Secretary of the Treasury of the United States (the “Secretary”) under the Small Business Lending Fund program. Pursuant to the Purchase Agreement, the Company issued 56,600 shares of the Company’s Senior Non-Cumulative Perpetual Preferred Stock, Series B (the “Series B Preferred Stock”), having a liquidation amount per share equal to $1,000, for a total purchase price of $56,600,000.
	The Series B Preferred Stock was entitled to receive non-cumulative dividends beginning October 1, 2011. The dividend rate, as a percentage of the liquidation amount, could fluctuate on a quarterly basis during the first ten quarters during which the Series B Preferred Stock is outstanding, based upon changes in the level of “Qualified Small Business Lending” or “QSBL” (as defined in the Purchase Agreement) by the Bank. The dividend rate for the first ten dividend periods was one percent (1%). For the eleventh calendar quarter through four and one half years after issuance, the dividend rate is fixed at one percent (1%) based upon the increase in QBSL as compared to the baseline. After four and one half years from issuance, the dividend rate will increase to nine percent (9%) if the stock has not been redeemed.
	The Series B Preferred Stock may be redeemed at any time at the Company’s option, at a redemption price of 100% of the liquidation amount plus accrued but unpaid dividends to the date of redemption for the current period, subject to the approval of its federal banking regulator.
	On November 18, 2011 under provisions of the CPP the Company issued to the Treasury warrants for 423,977 shares (as adjusted reflect the 10% stock dividend paid on June 14, 2013) of Company common stock at $6.76 per share (as adjusted for the 10% stock dividend paid on June 14, 2013) were sold by the Treasury. At December 31, 2014 those warrants remain outstanding and have an expiration date of December 8, 2018. Upon exercise, which is at the option of the holder, the Company will issue a number of shares of Company common stock in exchange for the warrants equal to the number of shares subject to the warrant less the number of shares determined by multiplying the number of shares subject to the warrant by the strike price and dividing the result by the current share price.
	Pursuant to the Merger Agreement, each of the 15,300 shares of Virginia Heritage Series A Preferred Stock, was exchanged for one share of the Company’s Series C Preferred Stock, which ranks equally with and has substantially identical terms and conditions as the Company’s existing Series B Preferred Stock.

	The Company maintains the 1998 Stock Option Plan (“1998 Plan”), the 2006 Stock Plan (“2006 Plan”) and the 2011 Employee Stock Purchase Plan (“2011 ESPP”).
	In connection with the acquisition of Fidelity, the Company assumed the Fidelity 2004 Long Term Incentive Plan and the 2005 Long Term Incentive Plan (the “Fidelity Plans”).
	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 1998 Plan, the Fidelity Plans or the Virginia Heritage Plans.
	The 2006 Plan provides for the issuance of awards of incentive stock options, non-qualifying stock options, restricted stock and stock appreciation rights to selected key employees and members of the Board. As amended, 1,996,500 shares of common stock are subject to issuance pursuant to awards under the 2006 Plan. Stock options and restricted stock awards are made with an exercise price equal to the average of the high and low price of the Company’s shares at the date of grant.
	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, and for restricted stock awards is based on the average of the high and low stock price of the Company’s shares 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. No performance-based awards are outstanding at December 31, 2014.
	In February 2014, the Company awarded three employees stock options to purchase 21,000 shares which have a ten-year term and vest in five substantially equal installments beginning on the first anniversary of the date of grant.
	In February 2014, the Company awarded 58,187 shares of restricted stock to senior officers and employees. The shares vest in three substantially equal installments beginning on the first anniversary of the date of grant.
	In March 2014, the Company awarded 20,760 shares of restricted stock to directors. The shares vest in three substantially equal installments beginning on the first anniversary of the date of grant.
	On October 31, 2014, in connection with the Merger, the Company assumed the outstanding options under the Virginia Heritage Plans, which were converted into fully vested options to acquire 401,497 shares of the Company’s common stock at exercise prices ranging from $9.22 to $22.70 per share and terms ranging from twenty-five months to one-hundred-twelve months.
	In November 2014, the Company awarded 8,680 shares of restricted stock to a senior officer and an employee. The shares vest in two substantially equal installments on the first and second anniversary from the date of grant.

	The total intrinsic value of outstanding stock options and outstanding exercisable stock options was $18.5 million and $10.2 million, respectively, at December 31, 2014 and 2013. The total intrinsic value of stock options exercised during the years ended December 31, 2014, 2013 and 2012 was $3.2 million, $3.1 million and $1.1 million, respectively. The total fair value of stock options vested was $10.1 million (including $10.0 million of stock options assumed from Virginia Heritage), $133 thousand and $136 thousand for 2014, 2013 and 2012, respectively. Unrecognized stock-based compensation expense related to stock options totaled $324 thousand at December 31, 2014. At such date, the weighted-average period over which this unrecognized expense was expected to be recognized was 3.67 years.

Compensation and Retirement Disclosure [Abstract]
Pension and Other Postretirement Benefits Disclosure [Text Block]	Note 17 – Supplemental Executive Retirement Plan
	In February 2013, the Compensation Committee authorized Supplemental Executive Retirement and Death Benefit Agreements (the “SERP Agreements”) with each 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 or alternatively, a lump sum payment at the option of the executive. 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 elected to finance the retirement benefits by purchasing fixed annuity contracts with three insurance carriers totaling $10.7 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. The annuity contracts accrued $50 thousand and $551 thousand respectively of income for the years ended December 31, 2014 and 2013, which is included in other noninterest income on the Consolidated Statement of Operations. The cash surrender value of the annuity contracts is $11.3 million at December 31, 2014 and is included in Other assets on the Consolidated Balance Sheet. For the years ended December 31, 2014 and 2013, the Company recorded benefit expense of $1.9 and $1.7 million respectively for this post retirement benefit.
	Upon death of an executive, the annuity contract related to such executive terminates. The Bank purchased in 2013 additional bank owned life insurance contracts, which would effectively fund its minimum payment obligation (up to the 15 year certain amount) to the executives’ named beneficiaries.

Financial Instruments Disclosure [Text Block]	Note 18 – Financial Instruments with Off-Balance Sheet Risk
	Various commitments to extend credit are made in the normal course of banking business. Letters of credit are also issued for the benefit of customers. These commitments are subject to loan underwriting standards and geographic boundaries consistent with the Company’s loans outstanding.
	Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since some of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.
	Loan commitments outstanding and lines and letters of credit at December 31, 2014 and 2013 are as follows:
	(dollars in thousands)	2014		2013
	Unfunded loan commitments	$	1,625,957	$	1,150,556
	Unfunded lines of credit		105,895		79,786
	Letters of credit		75,615		51,768
	Total	$	1,807,467	$	1,282,110
	Because most of the Company’s business activity is with customers located in the Washington, D.C., metropolitan area, a geographic concentration of credit risk exists within the loan portfolio, the performance of which will be influenced by the economy of the region.
	The Bank maintains a reserve for the potential repurchase of residential mortgage loans, which amounted to $101 thousand at December 31, 2014 and $57 thousand at December 31, 2013. These amounts are included in Other liabilities in the accompanying Consolidated Balance Sheets. Changes in the balance of the reserve are a component of Other expenses in the accompanying Consolidated Statements of Operations. The reserve is available to absorb losses on the repurchase of loans sold related to document and other fraud, early payment default and early payoff. Through December 31, 2014, no reserve charges have occurred related to fraud or early payment default.
	The Company enters into interest rate lock commitments, which are commitments to originate loans whereby the interest rate on the loan is determined prior to funding and the customers have locked into that interest rate. The residential mortgage division either locks the loan and rate in with an investor and commits to deliver the loan if settlement occurs under best efforts or commits to deliver the locked loan in a binding mandatory delivery program with an investor. Certain loans under rate lock commitments are covered under forward sales contracts of mortgage backed securities. Forward sales contracts of mortgage backed securities 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 Company determines the fair value of rate lock commitments and delivery contracts by measuring the fair value of the underlying asset, which is impacted by current interest rates and taking into consideration the probability that the rate lock commitments will close or will be funded.

Regulatory Capital Requirements under Banking Regulations [Text Block]	Note 20 – Regulatory Matters
	The Company and Bank are subject to various regulatory capital requirements administered by the Federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weighting, and other factors.
	Quantitative measures established by regulation to ensure capital adequacy require the Company and Bank to maintain amounts and ratios (set forth in the table below) of total capital and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined). Management believes, as of December 31, 2014 and 2013, that the Company and Bank met all capital adequacy requirements to which they are subject.
	The actual capital amounts and ratios for the Company and Bank as of December 31, 2014 and 2013 are presented in the table below:

Disclosure Text Block [Abstract]
Fair Value, Measurement Inputs, Disclosure [Text Block]	Note 22 – 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,” establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:
		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.

	Investment Securities Available-for-Sale
	Investment securities available-for-sale are recorded at fair value on a recurring basis. 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. Government agency debt securities, mortgage backed securities issued by government sponsored entities and municipal bonds. Securities classified as Level 3 include securities in less liquid markets, the carrying amount approximate the fair value.
	The Company’s residential loans held for sale are reported on an aggregate basis at the lower of cost or fair value.
	The following is a reconciliation of activity for assets measured at fair value based on Significant Other Unobservable Inputs (Level 3):

	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.
	Loans held for sale: Loans held for sale are carried at the lower of cost or market value. The fair value of loans held for sale is based on what secondary markets are currently offering for portfolios with similar characteristics. As such, the Company classifies loans subjected to nonrecurring fair value adjustments as Level 2 valuation.
	Impaired loans: The Company considers a loan impaired when it is probable that the Company will be unable to collect all amounts due according to the original contractual terms of the note agreement, including both principal and interest. Management has determined that nonaccrual loans and loans that have had their terms restructured in a troubled debt restructuring meet this impaired loan definition. For individually evaluated impaired loans, the amount of impairment is based upon the present value of expected future cash flows discounted at the loan’s effective interest rate or the estimated fair value of the underlying collateral for collateral-dependent loans, which the Company classifies as a Level 3 valuation.
	Other real estate owned: Other real estate owned is initially recorded at the lower of carrying value or fair value. Fair value is based upon independent market prices, appraised values of the collateral or management’s estimation of the value of the collateral, which the Company classifies as a Level 3 valuation. Assets measured at fair value on a nonrecurring basis are included in the table below:

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.” The fair value of impaired loans is estimated using one of several methods, including the collateral value, market value of similar debt, enterprise value, liquidation value and discounted cash flows. Those impaired loans not requiring a specific allowance represent loans for which the fair value of expected repayments or collateral exceed the recorded investment in such loans. At December 31, 2014, substantially all of the totally impaired loans were evaluated based upon the fair value of the collateral. In accordance with ASC Topic 820, impaired loans where an allowance is established based on the fair value of collateral require classification in the fair value hierarchy. When the fair value of the collateral is based on an observable market price or a current appraised value, the Company records the loan as nonrecurring Level 2. When an appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value and there is no observable market price, the Company records the loan as nonrecurring Level 3.
Except for collateral dependent loans, the fair values for loans acquired from Virginia Heritage were estimated using cash flow projections based on the remaining maturity and repricing terms. Cash flows were adjusted by estimating future credit losses and the rate of prepayments. Projected monthly cash flows were then discounted to present value using a risk-adjusted market rate for similar loans. For collateral dependent loans with deteriorated credit quality, fair value was estimated by analyzing the value of the underlying collateral, assuming the fair values of the loans were derived from the eventual sale of the collateral. These values were discounted using market derived rates of return, with consideration given to the period of time and costs associated with the foreclosure and disposition of the collateral.
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: For cash and due from banks and federal funds sold the carrying amount approximates fair value.
Interest bearing deposits with other banks: Values are estimated by discounting the future cash flows using the current rates at which similar deposits would be earning.
Investment securities: For these instruments, fair values are 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.
Federal Reserve and Federal Home Loan Bank stock: The carrying amount approximate the fair values at the reporting date.
Loans held for sale: Fair values are at the carrying value (lower of cost or market) since such loans are typically committed to be sold (servicing released) at a profit.
Loans: For variable rate loans that re-price on a scheduled basis, fair values are based on carrying values. The fair value of the remaining loans are estimated by discounting the estimated future cash flows using the current interest rate at which similar loans would be made to borrowers with similar credit ratings and for the same remaining term.
Bank owned life insurance: The fair value of bank owned life insurance is the current cash surrender value, which is the carrying value.
Annuity investment: The fair value of the annuity investments is the carrying amount at the reporting date.
Derivative financial instruments: Derivative instruments are used to hedge residential mortgage loans held for sale that utilize mandatory delivery and the related interest rate lock commitments and include forward commitments to sell those loans. The fair values of derivative financial instruments are based on derivative market data inputs as of the valuation date and the underlying value of mortgage loans for interest rate lock commitments.
Noninterest bearing deposits: The fair value of these deposits is the amount payable on demand at the reporting date, since generally accepted accounting standards do not permit an assumption of core deposit value.
Interest bearing deposits: The fair value of interest bearing transaction, savings, and money market deposits with no defined maturity is the amount payable on demand at the reporting date, since generally accepted accounting standards do not permit an assumption of core deposit value.
Certificates of deposit: The fair value of certificates of deposit is estimated by discounting the future cash flows using the current rates at which similar deposits with remaining maturities would be accepted.
Customer repurchase agreements and federal funds purchased: The carrying amount approximates the fair values at the reporting date.
Borrowings: The carrying amount for variable rate borrowings approximate the fair values at the reporting date. The fair value of fixed rate FHLB advances and the subordinated notes are estimated by computing the discounted value of contractual cash flows payable at current interest rates for obligations with similar remaining terms. The fair value of variable rate FHLB advances is estimated to be carrying value since these liabilities are based on a spread to a current pricing index.
Off-balance sheet items: Management has reviewed the unfunded portion of commitments to extend credit, as well as standby and other letters of credit, and has determined that the fair value of such instruments is equal to the fee, if any, collected and unamortized for the commitment made.
The estimated fair values of the Company’s financial instruments at December 31, 2014 and 2013 are as follows:

Accounting Policies [Abstract]
Nature of Operations [Text Block]	Nature of Operations
	The Company, through the Bank, conducts a full service community banking business, primarily in Northern Virginia, Montgomery County, Maryland, and Washington, D.C. On October 31, 2014, the Company completed its acquisition of Virginia Heritage Bank (“Virginia Heritage”). Refer to Note 2 for a full description of this transaction. 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 and the origination of small business loans. The guaranteed portion of small business loans, guaranteed by the Small Business Administration (“SBA”), is typically sold to third party investors in a transaction apart from the loan’s origination. As of December 31, 2014, the Bank offers its products and services through twenty two 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, Policy [Policy Text Block]	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.
Business Combinations Policy [Policy Text Block]	Business Combinations
	Business combinations are accounted for by applying the acquisition method in accordance with Accounting Standards Codification (“ASC”) 805, Business Combinations. Under the acquisition method, identifiable assets acquired and liabilities assumed, and any non-controlling interest in the acquiree at the acquisition date are measured at their fair values as of that date, and are recognized separately from goodwill. Results of operations of the acquired entities are included in the consolidated statement of income from the date of acquisition.
Cash and Cash Equivalents, Policy [Policy Text Block]	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.
Trade and Loan Receivables, Nonmortgage Loans Held-for-sale, Policy [Policy Text Block]	Loans Held for Sale
	The Company engages in sales of residential mortgage loans and the guaranteed portion of SBA loans originated by the Bank. Loans held for sale are carried at the lower of aggregate cost or 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 on a servicing released basis, and, therefore, it has no intangible asset recorded for the value of such servicing as of December 31, 2014 and December 31, 2013. The sale of the guaranteed portion of SBA loans on a servicing retained basis 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 statement 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. rate lock commitments). Such 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 decrease 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 Company 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 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 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 rate lock commitments on mortgage loans to be sold in the secondary market are considered to be derivatives the Company manages the interest rate risk on 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, with changes in fair value recorded in other income. 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.
	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 at fair value.
Marketable Securities, Policy [Policy Text Block]	Investment Securities
	The Company has no securities classified as trading, nor are any investment securities classified as held to maturity. Marketable equity securities and debt securities not classified as held to maturity or trading are classified as available-for-sale. 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 prepayments and call optionality. 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: (1) duration and magnitude of the decline in value; (2) the 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 debt security; (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.
Finance, Loans and Leases Receivable, Policy [Policy Text Block]	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 on loans 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 (ninety 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 the cash basis.
Revenue Recognition, Policy [Policy Text Block]	Higher Risk Lending – Revenue Recognition
	The Company has occasionally made higher risk acquisition, development, and construction (“ADC”) loans that entail higher risks than ADC loans made following normal underwriting practices (“higher risk loan transactions”). These higher risk loan transactions are currently made through the Company’s subsidiary, ECV. This activity is 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 and meet the loan classification requirements of the Accounting Standard Executive Committee (“AcSEC”) guidance reprinted from the CPA Letter, Special Supplement, dated February 10, 1986 (also referred to as Exhibit 1 to AcSEC Practice Bulletin No. 1). Additional interest earned on these higher risk loan transactions (as defined in the individual loan agreements) is recognized as realized under the provisions contained in AcSEC’s guidance reprinted from the CPA Letter, Special Supplement, dated February 10, 1986 (also referred to as Exhibit 1 to AcSEC Practice Bulletin No.1) and Staff Accounting Bulletin No. 101 (Revenue Recognition in Financial Statements). Certain additional interest is included as a component of noninterest income.  ECV recorded no additional interest on higher risk transactions during 2014, 2013 or 2012 (although normal interest income was recorded) and had four higher risk lending transactions outstanding as of December 31, 2014, as compared to five higher risk lending transaction outstanding as of December 31, 2013, amounting to $6.2 million and $7.4 million, respectively.
Financing Receivable, Allowance for Credit Losses, Policy or Methodology Change [Policy Text Block]	Allowance for Credit Losses
	The allowance for credit losses represents an amount, which in management’s judgment, is adequate to absorb probable losses on existing 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 ASC Topic 450, “Contingencies,” or ASC Topic 310, “Receivables.” Specific allowances are established in cases where management has identified significant conditions or circumstances related to a specific credit that management believes indicate the probability that a loss may be incurred. For potential problem credits for which specific allowance amounts have not been determined, the Company establishes allowances according to the application of credit risk factors. These factors are set by management and approved by the appropriate Board committee to reflect its assessment of the relative level of risk inherent in each risk grade. A third component of the allowance computation, termed a nonspecific or environmental factors allowance, is based upon management’s evaluation of various environmental conditions that are not directly measured in the determination of either the specific allowance or formula allowance. Such conditions include general economic and business conditions affecting key lending areas, credit quality trends (including trends in delinquencies and nonperforming loans expected to result from existing conditions), loan volumes and concentrations, specific industry conditions within portfolio categories, recent loss experience in particular loan categories, duration of the current business cycle, bank regulatory examination results, findings of outside review consultants, and management’s judgment with respect to various other conditions including credit administration and management and the quality of risk identification systems. Executive management reviews these environmental conditions quarterly, and documents the rationale for all changes.
	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 regulatory 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.
Property, Plant and Equipment, Policy [Policy Text Block]	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 seven years for furniture, fixtures and equipment, three to five years for computer software and hardware, and ten to forty years for buildings and 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.
Real Estate, Policy [Policy Text Block]	Other Real Estate Owned (“OREO”)
	Assets acquired through loan foreclosure are held for sale and are initially recorded at fair value less estimated selling costs when acquired, establishing a new cost basis. The new basis is supported by recent appraisals. 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 Intangible Assets, Goodwill, Policy [Policy Text Block]	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 and other intangibles are 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 quantitative assessments of all reporting units, the Company concluded that no impairment existed at December 31, 2014. 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.
Repurchase and Resale Agreements Policy [Policy Text Block]	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.
Advertising Cost, Policy, Expensed Advertising Cost [Policy Text Block]	Marketing and Advertising
	Marketing and advertising costs are generally expensed as incurred.
Income Tax, Policy [Policy Text Block]	Income Taxes
	The Company employs the liability method of accounting for income taxes as required by ASC Topic 740, “Income Taxes.” Under the liability method, deferred-tax assets and liabilities are determined based on differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities (i.e., temporary timing differences) and are measured at the enacted rates that will be in effect when these differences reverse. The Company utilizes statutory requirements for its income tax accounting, and avoids risks associated with potentially problematic tax positions that may incur challenge upon audit, where an adverse outcome is more likely than not. Therefore, no provisions are made in the Company’s tax reserves for uncertain tax positions or accompanying potential tax penalties and interest for underpayments of income taxes. In accordance with ASC Topic 740, the Company may establish a reserve against deferred tax assets in those cases where realization is less than certain, although no such reserves exist at either December 31, 2014 or December 31, 2013.
Transfers and Servicing of Financial Assets, Policy [Policy Text Block]	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 obtain 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 be deemed immaterial based on the specific facts and circumstances.
Earnings Per Share, Policy [Policy Text Block]	Earnings per Common Share
	Basic net income per common share is derived by dividing net income available to common shareholders by the weighted-average number of common shares outstanding during the period measured. Diluted earnings per common share is computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding during the period measured including the potential dilutive effects of common stock equivalents. Earnings per share amounts for periods ending prior to June 30, 2013 have been adjusted to reflect a 10% stock dividend paid on June 14, 2013.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock-Based Compensation
	In accordance with ASC Topic 718, “Compensation,” the Company records as compensation expense an amount equal to the amortization (over the remaining service period) of the fair value (computed at the date of option grant) of any outstanding fixed stock option grant and restricted stock award. Compensation expense on variable stock option grants (i.e. performance based grants) if any, is recorded based on the probability of achievement of the goals underlying the performance grant. Refer to Note 13 for a description of stock-based compensation awards, activity and expense for the years ended December 31, 2014, 2013 and 2012.
New Accounting Pronouncements, Policy [Policy Text Block]	New Authoritative Accounting Guidance
	In January 2014, the FASB issued ASU No. 2014-01, "Accounting for Investments in Qualified Affordable Housing Projects." ASU No. 2014-01 permits reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognize the net investment performance in the income statement as a component of income tax expense. This new guidance also requires new disclosures for all investors in these projects. ASU No. 2014-01 is effective for interim and annual reporting periods beginning after December 15, 2014. Upon adoption, the guidance must be applied retrospectively to all periods presented. However, entities that use the effective yield method to account for investments in these projects before adoption may continue to do so for these pre-existing investments. The Company currently accounts for such investments using the effective yield method and plans to continue to do so for these pre-existing investments after adopting ASU No. 2014-01 on January 1, 2015. The Company expects investments made after January 1, 2015 to meet the criteria required for the proportional amortization method and plans to make such an accounting policy election. The adoption of ASU No. 2014-01 is not expected to have a material impact on the Company's consolidated financial statements.
	In January 2014, the FASB issued ASU No. 2014-04, "Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure." The objective of this guidance is to clarify when an in substance repossession or foreclosure occurs, that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be derecognized and the real estate property recognized. ASU No. 2014-04 states that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, ASU No. 2014-04 requires interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. ASU No. 2014-04 is effective for interim and annual reporting periods beginning after December 15, 2014. The adoption of ASU No. 2014-04 is not expected to have a material impact on the Company's consolidated financial statements

[1]	In connection with the Fidelity acquisition (August 2008), one branch purchase (January 2011), and the Virginia Heritage acquisition, the Company made anallocation of the purchase price to the core deposit intangibles which were $2.3 million, $215 thousand, and $4.6 million respectively based on an independentevaluation. The amount of the core deposit intangible relating to the one branch acquisition was fully amortized at December 31, 2013. The amount of the coredeposit intangible relating to the Fidelity acquisition at December 31, 2014 was $804 thousand, which is being amortized over its remaining economic life of 1.2years as a component of other noninterest expense. The amount of the core deposit intangible relating to the Virginia Heritage acquisition at December 31,2014 was $4.4 million, which is being amortized over its remaining economic life of 6 years as a component of other noninterest expense.
[2]	The Company recognizes a servicing asset for the computed value of servicing fees on the sale of the guaranteed portion of SBA loans, which is in excess ofa normal servicing fee. Assumptions related to the loan term and amortization period are made to arrive at the initial recorded value.
[3]	The Company recorded an initial amount of unidentified intangible (goodwill) incident to the acquisition of Fidelity & Trust Financial Corporation ("Fidelity")of approximately $360 thousand. Based on allowable adjustments through August 31, 2009, the unidentified intangible (goodwill) amounted to approximately $2.2 million. The Company recorded an initial amount of unidentified intangible (goodwill) incident to the acquisition of Virginia Heritage of approximately $102.3 million.
