Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Banking Activities and Significant Accounting Policies	Nature of Banking Activities and Significant Accounting Policies
	Middleburg Financial Corporation (the “Company”) is a bank holding company and through its banking subsidiary, Middleburg Bank, grants commercial, financial, agricultural, residential and consumer loans to customers principally in Loudoun County, Fauquier County and Fairfax County, Virginia as well as the Town of Williamsburg and the City of Richmond.  The loan portfolio is well diversified and generally is collateralized by assets of the borrowers.  The loans are expected to be repaid from cash flow or proceeds from the sale of selected assets of the borrowers.  Middleburg Trust Company is a non-banking subsidiary of Middleburg Financial Corporation which offers a comprehensive range of fiduciary and investment management services to individuals and businesses.  On May 15, 2014, Middleburg Financial Corporation, through its banking subsidiary, Middleburg Bank, sold all of its majority interest in Southern Trust Mortgage LLC, which originated and sold mortgages secured by personal residences primarily in the southeastern United States.
	The accounting and reporting policies of the Company conform to U. S. generally accepted accounting principles and to accepted practice within the banking industry.
	Principles of Consolidation
	The consolidated financial statements of Middleburg Financial Corporation and its wholly owned subsidiaries, Middleburg Bank, Middleburg Investment Group, Inc., Middleburg Trust Company and Middleburg Bank Service Corporation include the accounts of all companies.  Through May 15, 2014, the Company owned 62.3% of the issued and outstanding membership interest units of Southern Trust Mortgage, through its subsidiary, Middleburg Bank. The issued and outstanding interest of Southern Trust Mortgage not held by the Company is reported as Non-Controlling Interest in Consolidated Subsidiary.  Accounting Standards Codification Topic 810, Consolidation, requires that the Company no longer eliminate through consolidation the equity investment in MFC Capital Trust II, which approximated $155,000 for each of the years ended December 31, 2014 and 2013.  The subordinate debt of the trust preferred entity is reflected as a liability of the Company.  All material intercompany balances and transactions have been eliminated in consolidation.
	Securities
	Certain debt securities that management has the positive intent and ability to hold until maturity are classified as "held-to-maturity" and recorded at amortized cost. Securities not classified as held-to-maturity, including equity securities with readily determinable fair values, are classified as "available-for-sale" and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income (loss). Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method.
	Equity investments in the FHLB and the Federal Reserve Bank of Richmond are separately classified as restricted securities and are carried at cost.
	Impairment of securities occurs when the fair value of a security is less than its amortized cost.  For debt securities, impairment is considered other-than-temporary and recognized in its entirety in net income if either (i) the intent is to sell the security or (ii) it is more likely than not that it will be necessary to sell the security prior to recovery of its amortized cost.  If, however, management’s intent is not to sell the security and it is not more than likely that management will be required to sell the security before recovery, management must determine what portion of the impairment is attributable to credit loss, which occurs when the amortized cost of the security exceeds the present value of the cash flows expected to be collected from the security.  If there is no credit loss, there is no other-than-temporary impairment.  If there is a credit loss, other-than-temporary impairment exists and the credit loss must be recognized in net income and the remaining portion of impairment must be recognized in other comprehensive income (loss).
	For equity securities carried at cost as restricted securities, impairment is considered to be other-than-temporary based on our ability and intent to hold the investment until a recovery of fair value.  Other-than-temporary impairment of an equity security results in a write-down that must be included in income.  We regularly review each security for other-than-temporary impairment based on criteria that include the extent to which cost exceeds market price, the duration of that market decline, the financial health of and specific prospects for the issuer, our best estimate of the present value of cash flows expected to be collected from debt securities, the intention with regards to holding the security to maturity and the likelihood that we would be required to sell the security before recovery.
	Loans
	The Company grants mortgage, commercial, and consumer loans to clients.  The loan portfolio is segmented into commercial loans, real estate loans, and consumer loans.  Real estate loans are further divided into the following classes:  construction; farmland; 1-4 family residential; and other real estate loans.  Descriptions of the Company’s loan classes are as follows:
	Commercial Loans: Commercial loans are typically secured with non-real estate commercial property.  The Company makes commercial loans primarily to middle market businesses located within our market area.
	Real Estate Loans – Construction: The Company originates construction loans for the acquisition and development of land and construction of condominiums, townhomes, and 1-4 family residences. This class also includes acquisition, development and construction loans for retail and other commercial purposes, primarily in our market areas.
	Real Estate Loans- Farmland:  Loans secured by agricultural property and not included in Real Estate – Other.
	Real Estate Loans – 1-4 Family:  This class of loans includes loans secured by 1-4 family homes.  The Company’s general practice is to sell the majority of its newly originated fixed-rate residential real estate loans in the secondary mortgage market, and to hold in its portfolio adjustable rate residential real estate loans and loans in close proximity to its financial service centers.
	Real Estate Loans – Other: This loan class consists primarily of loans secured by multi-unit residential property and owner and non-owner occupied commercial and industrial property.  This class also includes loans secured by real estate which do not fall into other classifications.
	Consumer Loans: Consumer loans include all loans made to individuals for consumer or personal purposes.  They include new and used auto loans, unsecured loans, lines of credit and home equity loans and lines of credit.
	The ability of the debtors to honor their contracts is dependent upon the real estate and general economic conditions in this area.
	For all classes of loans, the Company considers loans to be past due when a payment is not received by the payment due date according to the contractual terms of the loan.  The Company monitors past due loans according to the following categories: less than 30 days past due, 30 – 59 days past due, 60 – 89 days past due, and 90 days or greater past due. The accrual of interest on all classes of loans is discontinued at the time the loans are 90 days delinquent unless they are well-secured and in the process of collection.
	Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off generally are reported at their outstanding unpaid principal balances adjusted for charge-offs, the allowance for loan losses, and any deferred fees or costs on originated loans.  Deferred fees and costs include discounts and premiums on syndicated and guaranteed loans purchased. Interest income is accrued on the unpaid principal balance.  Loan origination and commitment fees, net of certain direct loan origination costs, are deferred and recognized as an adjustment of the loan yield over the life of the related loan.
	All interest accrued but not collected for loans that are placed on nonaccrual or charged-off is reversed against interest income.  The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual.  Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
	Allowance for Loan Losses
	The allowance for loan losses reflects management’s judgment of probable loan losses inherent in the portfolio at the balance sheet date.  Management uses a disciplined process and methodology to establish the allowance for losses each quarter.  To determine the total allowance for loan losses, the Company estimates the reserves needed for each segment of the portfolio, including loans analyzed individually and loans analyzed on a pooled basis.  The allowance for loan losses consists of amounts applicable to:  (i) the commercial loan portfolio; (ii) the real estate portfolio; and (iii) the consumer loan portfolio.
	To determine the allowance for loan losses, loans are pooled by portfolio segment and losses are modeled using historical experience, and quantitative and other mathematical techniques over the loss emergence period.  Each class of loan requires exercising significant judgment to determine the estimation that fits the credit risk characteristics of its portfolio segment.  The Company uses internally developed models in this process.  Management must use judgment in establishing additional input metrics for the modeling processes.  The models and assumptions used to determine the allowance are reviewed to ensure that their theoretical foundation, assumptions, data integrity, computational processes, reporting practices, and end user controls are appropriate and properly documented.
	The establishment of the allowance for loan losses relies on a consistent process that requires multiple layers of management review and judgment and responds to changes in economic conditions, customer behavior, and collateral value, among other influences.  From time to time, events or economic factors may affect the loan portfolio, causing management to provide additional amounts to or release balances from the allowance for loan losses.  Qualitative factors considered in the allowance for loan losses evaluation include the levels and trends in delinquencies and nonperforming loans, trends in volume and terms of loans, the effects of any changes in lending policies, the experience, ability, and depth of management, national and local economic trends and conditions, concentrations of credit, the quality of the Company’s loan review system, competition and regulatory requirements.  The Company’s allowance for loan losses is sensitive to risk ratings and economic assumptions and delinquency trends driving statistically modeled reserves.  Individual loan risk ratings are evaluated based on each situation by experienced senior credit officers.
	Management monitors differences between estimated and actual incurred loan losses.  This monitoring process includes periodic assessments by senior management of loan portfolios and the models used to estimate incurred losses in those portfolios.  Additions to the allowance for loan losses are made by charges to the provision for loan losses.  Credit exposures deemed to be uncollectible are charged against the allowance for loan losses.  Recoveries of previously charged-off amounts are credited to the allowance for loans losses.
	Loan Charge-off Policies
	Commercial and consumer loans are generally charged off when:
	•they are 90 days past due;
	•the collateral is repossessed; or
	•the borrower has filed bankruptcy.
	All classes of real estate loans are charged down to the net realizable value when the Company determines that the sole source of repayment is liquidation of the collateral.
	Impaired Loans
	For all classes of loans, a loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement.  Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due.  Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired.  Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed.
	For all classes of loans, impairment is measured on a loan-by-loan basis by comparing the loan balance to either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent. Any variance in values is charged-off when determined.
	Troubled Debt Restructurings
	In situations where, for economic or legal reasons related to a borrower’s financial condition, management may grant a concession to the borrower that it would not otherwise consider, the related loan is classified as a troubled debt restructuring (“TDR”).  Management strives to identify borrowers in financial difficulty early and works with them to modify their loan to more affordable terms before their loan reaches nonaccrual status.  These modified terms may include rate reductions, principal forgiveness, payment forbearance and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of the collateral.  In cases where borrowers are granted new terms that provide for a reduction of either interest or principal, management measures any impairment on the restructuring as noted above for impaired loans. All identified TDRs are considered to be impaired loans.
	Management considers troubled debt restructurings and subsequent defaults in restructured loans in the determination of the adequacy of the Company's allowance for loan losses. When identified as a TDR, a loan is evaluated for potential loss as noted above for impaired loans. Loans identified as TDRs frequently are on nonaccrual status at the time of the restructuring and, in some cases, partial charge-offs may have already been taken against the loan and a specific allowance may have already been established for the loan. As a result of any modification as a TDR, the specific reserve associated with the loan may be increased. Additionally, loans modified in a TDR are closely monitored for delinquency as an early indicator of possible future defaults. If loans modified in a TDR subsequently default, the Company evaluates them for possible further impairment. As a result, any specific allowance may be increased, adjustments may be made in the allocation of the total allowance balance, or partial charge-offs may be taken to further write-down the carrying value of the loan. Management exercises significant judgment in developing estimates for potential losses associated with TDRs.
	Mortgage Loans Held for Sale
	Mortgage loans held for sale are carried at the lower of aggregate cost or fair value. The fair value of mortgage loans held for sale is determined using current secondary market prices for loans with similar coupons, maturities, and credit quality and fair value of loans committed at year-end. There has been no significant activity since May 15, 2014, the date the Company sold its majority interest in Southern Trust Mortgage, and therefore, there were no loans held for sale on the consolidated balance sheet as of December 31, 2014.
	Premises and Equipment
	Land is carried at cost.  Premises and equipment are stated at cost less accumulated depreciation.  Depreciation of property and equipment is computed principally on the straight-line method over the following estimated useful lives:
		Years
	Buildings and improvements	Oct-40
	Furniture and equipment	15-Mar
	Maintenance and repairs of property and equipment are charged to operations and major improvements are capitalized.  Upon retirement, sale, or other disposition of property and equipment, the cost and accumulated depreciation are eliminated from the accounts and gain or loss is included in income.
	Other Real Estate Owned and Repossessed Assets
	Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value less costs to sell at the date of foreclosure. Subsequent to foreclosure, management periodically performs valuations of the foreclosed assets based on updated appraisals, general market conditions, recent sales of like properties, length of time the properties have been held, and our ability and intention with regard to continued ownership of the properties. The Company may incur additional write-downs of foreclosed assets to fair value less costs to sell if valuations indicate a further deterioration in market conditions. Revenue and expenses from operations and changes in the property valuations are included in net expenses from foreclosed assets and improvements are capitalized.
	Goodwill and Intangible Assets
	With the adoption of Accounting Standards Update (ASU) 2011-08, "Intangible-Goodwill and Other-Testing Goodwill for Impairment", the Company is no longer required to perform a test for impairment unless, based on an assessment of qualitative factors related to goodwill, the Company determines that it is more likely than not that the fair value is less than its carrying amount. If the likelihood of impairment is more than 50%, the Company must perform a test for impairment and may be required to record impairment charges.
	Additionally, acquired intangible assets (customer relationships) are separately recognized and amortized over their useful life of 15 years.
	Bank-Owned Life Insurance
	The Company owns insurance on the lives of a certain group of key employees. The policies were purchased to help offset the increase in the costs of various fringe benefit plans, including healthcare. The cash surrender value of these policies is included as an asset on the consolidated balance sheets, and any increase in cash surrender value is recorded as non-interest income on the consolidated statements of income. In the event of the death of an insured individual under these policies, the Company would receive a death benefit which would be recorded as other income.
	Income Taxes
	Deferred income tax assets and liabilities are determined using the balance sheet method. Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws.
	When tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained.  The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any.  Tax positions taken are not offset or aggregated with other positions.  Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50% likely of being realized upon settlement with the applicable taxing authority.  The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits in the accompanying consolidated balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination.  Interest and penalties associated with unrecognized tax benefits are classified as additional income taxes in the consolidated statements of income. No liabilities for unrecognized tax benefits have been recognized as of December 31, 2014 or 2013.
	Trust Company Assets
	Securities and other properties held by Middleburg Trust Company in a fiduciary or agency capacity are not assets of the Company and are not included in the accompanying consolidated financial statements.
	Earnings Per Share
	Basic earnings per share represents income available to common shareholders divided by the weighted-average number of common shares outstanding during the period.  Nonvested restricted shares are included in basic earnings per share because of dividend participation rights. Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance.  Potential common shares that may be issued by the Company relate solely to outstanding stock options and the warrant, and are determined using the treasury stock method.
	Cash and Cash Equivalents
	For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from other banks and federal funds sold. Generally, federal funds are sold and purchased for one-day periods.
	Use of Estimates
The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.  Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, impairment of goodwill and intangible assets, valuation of other real estate owned, and other-than-temporary impairment of securities.
Advertising Costs
The Company follows the policy of charging the costs of advertising to expense as incurred.
Comprehensive Income (Loss)
Accounting principles generally require that recognized revenue, expenses, gains, and losses be included in net income.  Although certain changes in assets and liabilities, such as unrealized gains and losses on available for sale securities, and changes in the fair value of interest rate swaps, are reported as a separate component of the equity section of the consolidated balance sheets, such items, along with net income, are components of comprehensive income (loss).
Securities Sold Under Agreements to Repurchase
Securities sold under agreements to repurchase are reflected at the amount of cash received in connection with the transaction.  The Company does not account for repurchase agreement transactions as sales.  All repurchase agreement transactions entered into by the Company are accounted for as collateralized financings. The Company may be required to provide additional collateral based on the fair value of the underlying securities.
Derivative Financial Instruments
The Company utilizes derivative financial instruments as a part of its asset-liability management program to control exposure to interest rate changes and fluctuations in market values and cash flows associated with certain financial instruments. The Company accounts for derivatives in accordance with ASC 815, "Derivatives and Hedging". Under current guidance, derivative transactions are classified as either cash flow hedges or fair value hedges or they are not designated as hedging instruments. The Company designates each transaction at its inception.
The Company documents all relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking various hedge transactions.  This process includes linking all derivatives that are designated as fair value hedges or cash flow hedges to specific assets or liabilities on the balance sheet.  The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are effective in offsetting changes in fair values or cash flows of hedged items.
As of December 31, 2014, the Company had both fair value and cash flow hedges on its balance sheet as well as derivative financial instruments that have not been designated as hedging instruments.  The derivatives are reported at fair value as of each balance sheet date. For designated cash flow hedges, the effective portions of changes in the fair value of the derivative are recorded in other comprehensive income (loss) and are recognized in the income statement when the hedged item affects earnings.  Ineffective portions of changes in the fair value of cash flow hedges are recognized in earnings as are changes in market value of derivatives not designated as hedging instruments.
Information concerning each of the Company's categories of derivatives as of December 31, 2014 and 2013 is presented in Note 24 to the consolidated financial statements.
Reclassifications
Certain reclassifications have been made to prior period balances to conform to current year presentation. No reclassifications were significant and had no effect on net income.
Transfers of Financial Assets
Transfers of financial assets are accounted for as sales when control over the assets has been surrendered.  Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Share-Based Employee Compensation Plan
At December 31, 2014, the Company had a share-based employee compensation plan which is described more fully in Note 8 to the consolidated financial statements. Compensation cost relating to share-based payment transactions is recognized in the consolidated financial statements.  That cost is measured based on the fair value of the equity instruments issued and recognized over the applicable vesting period.  The Company recognized $426,000, $492,000, and $440,000 in compensation expense during 2014, 2013, and 2012, respectively.
Recent Accounting Pronouncements
In January 2014, the FASB issued ASU 2014-01, “Investments-Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects (a consensus of the FASB Emerging Issues Task Force).” The amendments in this ASU permit 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 recognizes the net investment performance in the income statement as a component of income tax expense (benefit). The amendments in this ASU should be applied retrospectively to all periods presented. A reporting entity that uses the effective yield method to account for its investments in qualified affordable housing projects before the date of adoption may continue to apply the effective yield method for those preexisting investments. The amendments in this ASU are effective for annual periods and interim reporting periods within those annual periods, beginning after December 15, 2014. Early adoption is permitted. The Company is currently assessing the impact that ASU 2014-01 will have on its consolidated financial statements.
In January 2014, the FASB issued ASU 2014-04, “Receivables-Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure (a consensus of the FASB Emerging Issues Task Force).” The amendments in this ASU clarify 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, the amendments require 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. The amendments in this ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. The Company is currently assessing the impact that ASU 2014-04 will have on its consolidated financial statements.
In April 2014, the FASB issued ASU 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” The amendments in this ASU change the criteria for reporting discontinued operations while enhancing disclosures in this area. Under the new guidance, only disposals representing a strategic shift in operations should be presented as discontinued operations. Those strategic shifts should have a major effect on the organization’s operations and financial results and include disposals of a major geographic area, a major line of business, or a major equity method investment. The new guidance requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. Additionally, the new guidance requires disclosure of the pre-tax income attributable to a disposal of a significant part of an organization that does not qualify for discontinued operations reporting. The amendments in the ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. Early adoption is permitted. The Company does not expect the adoption of ASU 2014-08 to have a material impact on its consolidated financial statements.
In June 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers: Topic 606.” This ASU applies to any entity using U.S. GAAP that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards. The guidance supersedes the revenue recognition requirements in Topic 605, “Revenue Recognition,, most industry-specific guidance, and some cost guidance included in Subtopic 605-35, “Revenue Recognition-Construction-Type and Production-Type Contracts.” The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To be in alignment with the core principle, an entity must apply a five step process including: identification of the contract(s) with a customer, identification of performance obligations in the contract(s), determination of the transaction price, allocation of the transaction price to the performance obligations, and recognition of revenue when (or as) the entity satisfies a performance obligation. Additionally, the existing requirements for the recognition of a gain or loss on the transfer of nonfinancial assets that are not in a contract with a customer have also been amended to be consistent with the guidance on recognition and measurement. The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted. The Company is currently assessing the impact that ASU 2014-09 will have on its consolidated financial statements.
In June 2014, the FASB issued ASU 2014-10, “Development Stage Entities (Topic 915): Elimination of Certain Financial Reporting Requirements, Including an Amendment to Variable Interest Entities Guidance in Topic 810, Consolidation.” The amendments in this ASU remove all incremental financial reporting requirements from U.S. GAAP for development stage entities, including the removal of Topic 915, “Development Stage Entities,” from the FASB Accounting Standards Codification. In addition, this ASU adds an example disclosure and removes an exception provided to development stage entities in Topic 810, “Consolidation,” for determining whether an entity is a variable interest entity. The presentation and disclosure requirements in Topic 915 will no longer be required for the first annual period beginning after December 15, 2014. The revised consolidation standards are effective for annual periods beginning after December 15, 2015. Early adoption is permitted. The Company does not expect the adoption of ASU 2014-10 to have a material impact on its consolidated financial statements.
In June 2014, the FASB issued ASU No. 2014-11, “Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures.” This ASU aligns the accounting for repurchase-to-maturity transactions and repurchase agreements executed as a repurchase financing with the accounting for other typical repurchase agreements. The new guidance eliminates sale accounting for repurchase-to-maturity transactions and supersedes the guidance under which a transfer of a financial asset and a contemporaneous repurchase financing could be accounted for on a combined basis as a forward agreement. The amendments in the ASU also require a new disclosure for transactions economically similar to repurchase agreements in which the transferor retains substantially all of the exposure to the economic return on the transferred financial assets throughout the term of the transaction. Additional disclosures will be required for the nature of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings. The amendments in this ASU are effective for the first interim or annual period beginning after December 15, 2014; however, the disclosure for transactions accounted for as secured borrowings is required to be presented for annual periods beginning after December 15, 2014, and interim periods beginning after March 15, 2015. Early adoption is not permitted. The Company is currently assessing the impact that ASU 2014-11 will have on its consolidated financial statements.
In June 2014, the FASB issued ASU No. 2014-12, “Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period.” The new guidance applies to reporting entities that grant employees share-based payments in which the terms of the award allow a performance target to be achieved after the requisite service period. The amendments in the ASU require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. Existing guidance in “Compensation - Stock Compensation (Topic 718),” should be applied to account for these types of awards. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted and reporting entities may choose to apply the amendments in the ASU either on a prospective or retrospective basis. The Company is currently assessing the impact that ASU 2014-12 will have on its consolidated financial statements.
In August 2014, the FASB issued ASU No. 2014-14, “Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40): Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure.” The amendments in this ASU apply to creditors that hold government-guaranteed mortgage loans and are intended to eliminate the diversity in practice related to the classification of these guaranteed loans upon foreclosure. The new guidance stipulates that a mortgage loan be derecognized and a separate other receivable be recognized upon foreclosure if (1) the loan has a government guarantee that is not separable from the loan prior to foreclosure, (2) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim, and (3) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclosure, the other receivable should be measured on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2014. Entities may adopt the amendments on a prospective basis or modified retrospective basis as of the beginning of the annual period of adoption; however, the entity must apply the same method of transition as elected under ASU 2014-04. Early adoption is permitted provided the entity has already adopted ASU 2014-04. The Company is currently assessing the impact that ASU 2014-14 will have on its consolidated financial statements.
In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” This update is intended to provide guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. Management is required under the new guidance to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date the financial statements are issued when preparing financial statements for each interim and annual reporting period. If conditions or events are identified, the ASU specifies the process that must be followed by management and also clarifies the timing and content of going concern footnote disclosures in order to reduce diversity in practice. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2016. Early adoption is permitted. The Company does not expect the adoption of ASU 2014-15 to have a material impact on its consolidated financial statements.
In November 2014, the FASB issued ASU No. 2014-16, “Derivatives and Hedging (Topic 815): Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share Is More Akin to Debt or to Equity.” The amendments in ASU do not change the current criteria in U.S. GAAP for determining when separation of certain embedded derivative features in a hybrid financial instrument is required. The amendments clarify how current U.S. GAAP should be interpreted in evaluating the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share. Specifically, the amendments clarify that an entity should consider all relevant terms and features, including the embedded derivative feature being evaluated for bifurcation, in evaluating the nature of the host contract. Furthermore, the amendments clarify that no single term or feature would necessarily determine the economic characteristics and risks of the host contract. Rather, the nature of the host contract depends upon the economic characteristics and risks of the entire hybrid financial instrument. The amendments in this ASU also clarify that, in evaluating the nature of a host contract, an entity should assess the substance of the relevant terms and features (i.e., the relative strength of the debt-like or equity-like terms and features given the facts and circumstances) when considering how to weight those terms and features. The amendments in this ASU are effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption, including adoption in an interim period, is permitted. The Company does not expect the adoption of ASU 2014-16 to have a material impact on its consolidated financial statements.
In November 2014, the FASB issued ASU No. 2014-17, “Business Combinations (Topic 805): Pushdown Accounting.” The amendments in ASU provide an acquired entity with an option to apply pushdown accounting in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity. An acquired entity may elect the option to apply pushdown accounting in the reporting period in which the change-in-control event occurs. An acquired entity should determine whether to elect to apply pushdown accounting for each individual change-in-control event in which an acquirer obtains control of the acquired entity. If pushdown accounting is not applied in the reporting period in which the change-in-control event occurs, an acquired entity will have the option to elect to apply pushdown accounting in a subsequent reporting period to the acquired entity’s most recent change-in-control event. An election to apply pushdown accounting in a reporting period after the reporting period in which the change-in-control event occurred should be considered a change in accounting principle in accordance with Topic 250, Accounting Changes and Error Corrections. If pushdown accounting is applied to an individual change-in-control event, that election is irrevocable. The amendments in this ASU are effective on November 18, 2014. After the effective date, an acquired entity can make an election to apply the guidance to future change-in-control events or to its most recent change-in-control event. However, if the financial statements for the period in which the most recent change-in-control event occurred already have been issued or made available to be issued, the application of this guidance would be a change in accounting principle. The Company does not expect the adoption of ASU 2014-17 to have a material impact on its consolidated financial statements.
In January 2015, the FASB issued ASU No. 2015-01, “Income Statement-Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items.” The amendments in this ASU eliminate from U.S. GAAP the concept of extraordinary items. Subtopic 225-20, Income Statement - Extraordinary and Unusual Items, required that an entity separately classify, present, and disclose extraordinary events and transactions. Presently, an event or transaction is presumed to be an ordinary and usual activity of the reporting entity unless evidence clearly supports its classification as an extraordinary item. If an event or transaction meets the criteria for extraordinary classification, an entity is required to segregate the extraordinary item from the results of ordinary operations and show the item separately in the income statement, net of tax, after income from continuing operations. The entity also is required to disclose applicable income taxes and either present or disclose earnings-per-share data applicable to the extraordinary item. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The Company does not expect the adoption of ASU 2015-01 to have a material impact on its consolidated financial statements.

A total of 118 securities have been identified by the Company as temporarily impaired at December 31, 2014.  Of the 118 securities, 116 are investment grade and 2 are speculative grade.  Mortgage-backed securities make up the majority of temporarily impaired securities at December 31, 2014.  Market prices change daily and are affected by conditions beyond the control of the Company.  Although the Company has the ability to hold these securities until the temporary loss is recovered, decisions by management may necessitate a sale before the loss is fully recovered.  No such sales were anticipated or required as of December 31, 2014.  Investment decisions reflect the strategic asset/liability objectives of the Company.  The investment portfolio is analyzed frequently by the Company and managed to provide an overall positive impact to the Company’s income statement and balance sheet.
Trust preferred securities
As of December 31, 2014 and 2013 the Company held no trust preferred securities in its investment portfolio.
Other-than-temporary impairment losses
At December 31, 2014, the Company evaluated the investment portfolio for possible other-than-temporary impairment losses and concluded that no adverse change in cash flows occurred and did not consider any portfolio securities to be other-than-temporarily impaired.  Based on this analysis and because the Company does not intend to sell securities prior to maturity and it is more likely than not the Company will not be required to sell any securities before recovery of amortized cost basis, which may be at maturity. For debt securities related to corporate securities, the Company determined that there was no other adverse change in the cash flows as viewed by a market participant; therefore, the Company does not consider the investments in these assets to be other-than-temporarily impaired at December 31, 2014.  However, there is a risk that the Company’s continuing reviews could result in recognition of other-than-temporary impairment charges in the future. For the years ended December 31, 2014, 2013, and 2012, no credit related impairment losses were recognized by the Company.
The Company’s investment in FHLB stock totaled $3.6 million and $5.1 million at December 31, 2014 and 2013, respectively.  FHLB stock is generally viewed as a long-term investment and as a restricted security which is carried at cost because there is no market for the stock other than the FHLB or member institutions.  Therefore, when evaluating FHLB stock for impairment, its value is based on the ultimate recoverability of the par value rather than by recognizing temporary declines in value.  The Company does not consider this investment to be other-than-temporarily impaired at December 31, 2014, and no impairment has been recognized.  FHLB stock is shown in restricted securities on the consolidated balance sheets and is not part of the available for sale portfolio.
The Company also had an investment in Federal Reserve Bank (“FRB”) stock which totaled $1.7 million at December 31, 2014 and 2013, respectively. The investment in FRB stock is a required investment and is carried at cost since there is no ready market. The Company does not consider this investment to be other-than-temporarily impaired at December 31, 2014 and no impairment has been recognized. FRB stock is shown in the restricted securities line item on the consolidated balance sheets and is not part of the available for sale securities portfolio.

	If interest on nonaccrual loans had been accrued, such income would have approximated $544,000, $1.1 million, and $1.4 million for the years ended December 31, 2014, 2013, and 2012, respectively. The Company sold $6.6 million in loans during 2014, of which, $5.9 million were on nonaccrual status.
	The Company utilizes an internal asset classification system as a means of measuring and monitoring credit risk in the loan portfolio.  Under the Company’s classification system, problem and potential problem loans are classified as “Special Mention”, “Substandard”, and “Doubtful”.
	Special Mention:  Loans with potential weaknesses that deserve management’s close attention.  If  left uncorrected, the potential weaknesses may result in the deterioration of the repayment prospects for the credit.
	Substandard:  Loans with well-defined weakness that jeopardize the liquidation of the debt.  Either the paying capacity of the borrower or the value of the collateral may be inadequate to protect the Company from potential losses.
	Doubtful:  Loans with a very high possibility of loss.  However, because of important and reasonably specific pending factors, classification as a loss is deferred until a more exact status may be determined.
	Loss: Loans are deemed uncollectible and are charged off immediately.
	The following tables present the recorded investment in loans by class of loan that have been classified according to the internal classification system as of December 31, 2014 and 2013, respectively:

The “Recorded Investment” amounts in the table above represent the outstanding principal balance net of charge-offs and nonaccrual payments to interest on each loan represented in the table.  The “Unpaid Principal Balance” represents the outstanding principal balance on each loan represented in the table plus any amounts that have been charged-off on each loan and nonaccrual payments applied to principal.
Included in certain loan categories of impaired loans are troubled debt restructurings (“TDRs”). The total balance of TDRs at December 31, 2014 was $6.9 million of which $2.6 million were included in the Company’s nonaccrual loan totals at that date and $4.3 million represented loans performing as agreed according to the restructured terms. This compares with $15.6 million in total restructured loans at December 31, 2013.  The amount of the valuation allowance related to TDRs was $517,000 and $2.8 million as of December 31, 2014 and 2013 respectively.
Loan modifications that were classified as TDRs during the years ended December 31, 2014 and 2013 were as follows:
		Year Ended December 31,

Of the five contracts classified as TDRs during 2014, two were sold and two were paid off totaling $907,000. The interest rate was lowered for the one remaining contract outstanding. There were no outstanding commitments to lend additional amounts to troubled debt restructured borrowers at December 31, 2014. During 2013, of the 23 loans that were considered to be TDRs, the terms were extended for 18 loans, the interest rates were lowered for 18 loans and 12 loans were placed on interest only payment methods.
During the year ended December 31, 2014, the Company identified as TDRs two loans for which the allowance for loan losses had previously been measured under a general allowance methodology. Upon identifying these loans as TDRs, the Company evaluated them for impairment. The accounting amendments require prospective application of the impairment measurement guidance for those loans newly identified as impaired. As of December 31, 2014, the recorded investment in the loans restructured during 2014 for which the allowance was previously measured under a general allowance methodology was $916,000, and there was no allowance for loan losses associated with those loans on the basis of a current evaluation of loss.
During the year ended December 31, 2013, the Company identified as TDRs, 13 loans for which the allowance for loan losses had previously been measured under a general allowance methodology. Upon identifying these loans as TDRs, the Company evaluated them for impairment. As of December 31, 2013, the recorded investment in the loans restructured during 2013 for which the allowance was previously measured under a general allowance methodology was $3.5 million, and the allowance for loan losses associated with those loans, on the basis of a current evaluation of loss was $1.3 million.
TDR payment defaults as of December 31, 2014 and December 31, 2013 were as follows:
		Year Ended December 31,

Share-Based Compensation Plan	Share-Based Compensation Plan
	The Company sponsors one share-based compensation plan, the 2006 Equity Compensation Plan, which provides for the granting of stock options, stock appreciation rights, stock awards, performance share awards, incentive awards, and stock units.  The 2006 Equity Compensation Plan was approved by the Company’s shareholders at the Annual Meeting held on April 26, 2006, and has succeeded the Company’s 1997 Stock Incentive Plan.  Under the plan, the Company may grant share-based compensation to its directors, officers, employees, and other persons the Company determines have contributed to the profits or growth of the Company.  During 2013, the Company's Board of Directors and shareholders approved an amendment to this Plan to increase the number of shares reserved for issuance from 255,000 shares to 430,000 shares, an increase of 175,000 shares.
	The Company granted 35,000 shares of restricted stock on May 7, 2014 to certain employees and executive officers. The restricted stock awards are a hybrid performance and service-based awards that contain performance-based acceleration provisions if certain financial performance targets are met during pre-defined monitoring periods. If the performance targets are not met during the monitoring periods, only 50% of the awarded shares will vest on December 31, 2018. Under the terms of the award, vesting may be accelerated on a partial basis after December 31, 2016 depending on financial results for the years 2014 through 2016. Vesting may be accelerated each year thereafter until December 31, 2018 based on financial results as compared to a selected peer group for the preceding three years. If the stock award is not vested through acceleration, 50% of any unvested shares will become vested on December 31, 2018.  All unearned restricted stock grants are forfeited if the employee leaves the Company prior to vesting.
	The following service-based restricted stock, not included in the above group, were issued:
	•	On November 3, 2014, 2,000 shares of service-based restricted stock was issued to an employee. These shares will vest over a three-year period.
	•	On January 27, 2014 and May 7, 2014, 133 shares and 4,400 shares of restricted stock, respectively, were awarded to members of the board of directors. These shares will vest at 100% on April 30, 2014 and April 30, 2015, respectively.
	For the years ended December 31, 2014, 2013, and 2012, the Company recorded $426,000, $492,000, and $440,000, respectively, in share-based compensation expense related to restricted stock and option grants.  The total income tax benefit related to share-based compensation was $63,000, $54,000, and $79,000 in 2014, 2013, and 2012, respectively.
	The following table summarizes restricted stock awarded under the 2006 Equity Compensation Plan:

	The weighted-average remaining contractual term for non-vested grants at December 31, 2014, 2013, and 2012 was 3.5 , 3.9, and 4.3 years, respectively.  As of December 31, 2014, there was $1.4 million of total unrecognized compensation expense related to the non-vested service awards granted under the 2006 Equity Compensation Plan.
	The aggregate intrinsic value represents the amount by which the current market value of the underlying stock exceeds the exercise price. This amount changes based on changes in the market value of the Company’s common stock.

	There were no performance-based restricted stock granted during the years ended December 31, 2014, 2013, and 2012. Performance-based restricted stock awards vest based on the target levels being reached over a three-year period. Compensation expense is recognized based on the grant-date fair value of the awards and the estimated forfeiture rate associated with achieving the target result level. As of December 31, 2014, there was no unrecognized compensation expense related to non-vested awards.
	Stock options may be granted periodically to certain officers and employees under the Company’s share-based compensation plan at prices equal to the market value of the stock on the date the options are granted.  Options granted vest over a three-year time period over which 25% vests on each of the first and second anniversaries of the grant and 50% on the third anniversary of the grant. As of December 31, 2014, all outstanding option awards were vested and, accordingly, there was no unrecognized compensation expense related to unvested stock-based option awards. Shares issued in connection with stock option exercises may be issued from available treasury shares or from market purchases. There were no stock option awards granted during the years ended December 31, 2014, 2013 or 2012.

Employee Benefit Plans	Employee Benefit Plans
	401(k) Plan
	The Company has a 401(k) plan whereby a majority of employees participate in the plan.  Employees may contribute up to 100% of their compensation subject to certain limits based on federal tax laws.  The Company makes matching contributions equal to 50% of the first 6% of an employee’s compensation contributed to the plan.  Matching contributions vest to the employee equally over a five year period.  For the years ended December 31, 2014, 2013, and 2012, expense attributable to the plan amounted to $340,000, $355,000 and $308,000, respectively.
	Money Purchase Pension Plan (MPPP)
	The Middleburg Financial Corporation Defined Benefit Pension Plan was replaced by a Money Purchase Pension Plan effective on January 1, 2010. Employees who have attained age 21 and completed one year of service are eligible to participate in the plan as of the first day of the month following the completion of such eligibility provisions. Employees earn a year of service if they complete one thousand hours of service in a plan year. Service with Middleburg Financial Corporation and its subsidiaries prior to the effective date of the Plan counts toward a participant's initial eligibility to participate in the plan.
	Each year, a participant receives an allocation of an employer contribution equal to 6.5% of total compensation (up to the statutory maximum) plus an additional contribution of 2.75% of compensation in excess of the Social Security taxable wage base (up to the statutory maximum). To receive an allocation, the participant must complete one thousand hours of service in the plan year and be employed on the last day of the plan year. The requirement to be employed on the last day of the plan year does not apply if a participant dies, retires, or becomes disabled during the plan year.
	Participants become vested in their employer contributions according to a schedule which allows for graduated vesting and full vesting after five years of service. Service with Middleburg Financial Corporation and its subsidiaries prior to the effective date of the Plan count toward a participant's vested percentage.
	Assets are held in a pooled investment account managed by Middleburg Trust Company, a wholly owned subsidiary of the Company. Distributions may be made upon termination of employment, death or disability.
	The plan is administered by the Benefits Committee of the Company. The plan may be amended from time to time by the Board or its delegate and may be terminated by the Board at any time for any reason.
	For the years ended December 31, 2014 , 2013, and 2012 expense attributable to the plan was $898,000, $1.0 million, and $940,000, respectively.
	Deferred Compensation Plans
	The Company has adopted several deferred compensation plans; including a defined benefit SERP, an elective deferral plan for the Chairman, and a defined contribution SERP for certain Executive Officers.  The two plans for the Chairman made installment payouts in 2014, 2013 and 2012.  The defined contribution SERP for Executive Officers includes a vesting schedule, and is currently credited at a rate using the 10-year treasury plus 1.5%.  The deferred compensation expense for 2014, 2013, and 2012, was $222,000, $210,000, and $204,000, respectively. The plans are unfunded; however, life insurance has been acquired on the life of the employees in amounts sufficient to help meet the costs of the obligations.

Risks and Uncertainties [Abstract]
Financial Instruments With Off-Balance-Sheet Risk and Credit Risk	Financial Instruments With Off-Balance Sheet Risk and Credit Risk
	The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers and to reduce its own exposure to fluctuations in interest rates.  These financial instruments include commitments to extend credit, standby letters of credit, and interest rate swaps.  Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the balance sheet.  The contract or notional amounts of those instruments reflect the extent of involvement the Company has in particular classes of financial instruments.  See Note 24 for more information regarding the Company’s use of derivatives.
	The Company's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments.  The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments.
	A summary of the contract amount of the Company's exposure to off-balance sheet risk as of December 31, 2014 and 2013, is as follows:
	(Dollars in thousands)	2014		2013
	Financial instruments whose contract amounts represent credit risk:
	Commitments to extend credit	$	143,012	$	116,528
	Standby letters of credit	3,617		2,849
	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 many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.  The Company evaluates each customer's creditworthiness on a case-by-case basis.  The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management's credit evaluation of the counterparty.  Collateral held varies but may include accounts receivable, inventory, property and equipment, and income producing commercial properties.
	Unfunded commitments under lines of credit are commitments for possible future extensions of credit to existing customers.  Those lines of credit may not be drawn upon to the total extent to which the Company is committed.
	Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party.  Those guarantees are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing, and similar transactions.  The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.  The Company holds certificates of deposit, deposit accounts, and real estate as collateral supporting those commitments for which collateral is deemed necessary.
	The Company had approximately $2.9 million in deposits in financial institutions in excess of amounts insured by the Federal Deposit Insurance Corporation (FDIC) at December 31, 2014.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements
	The Company follows ASC 820, "Fair Value Measurements" to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures.  ASC 820 clarifies that fair value of certain assets and liabilities is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants.
	ASC 820 specifies a hierarchy of valuation techniques based on whether the inputs are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions.  The three levels of the fair value hierarchy under ASC 820 based on these two types of inputs are as follows:
	Level I.	Quoted prices are available in active markets for identical assets or liabilities as of the reported date.
	Level II.	Pricing inputs are other than the quoted prices in active markets, which are either directly or indirectly observable as of the reported date.  The nature of these assets and liabilities includes items for which quoted prices are available but traded less frequently and items that are fair-valued using other financial instruments, the parameters of which can be directly observed.
	Level III.	Assets and liabilities that have little to no pricing observability as of the reported date.  These items do not have two-way markets and are measured using management’s best estimate of fair value, where the inputs into the determination of fair value require significant management judgment or estimation.
	Measured on a recurring basis
	The following describes the valuation techniques and inputs used by the Company in determining the fair value of certain assets recorded at fair value on a recurring basis in the financial statements.
	Securities Available for Sale
	The Company primarily values its investment portfolio using Level II fair value measurements, but may also use Level I or Level III measurements if required by the composition of the portfolio. If quoted market prices are not available, fair values are measured utilizing independent valuation techniques of identical or similar securities for which significant assumptions are derived primarily from or corroborated by observable market data. Third party vendors compile prices from various sources and may determine the fair value of identical or similar securities by using pricing models that consider observable market data (Level II). In certain cases where there is limited activity or less transparency around inputs to the valuation, securities are classified as Level III of the valuation hierarchy.
	Loans Held for Sale
	Loans held for sale are carried at market value. These loans currently consist of 1-4 family residential loans originated for sale in the secondary market. Fair value is based on the price secondary markets are currently offering for similar loans using observable market data (Level II). Gains and losses on the sale of loans are recorded within income from mortgage banking activities on the consolidated statements of income. There has been no activity since May 15, 2014, the date the Company sold its majority interest in Southern Trust Mortgage, and therefore, there were no loans held for sale on the consolidated balance sheet as of December 31, 2014.
	Mortgage Interest Rate Locks
	The Company recognizes mortgage interest rate locks at fair value. Fair value is based on either (i) the price of the underlying loans obtained from an investor for loans that will be delivered on a best efforts basis or (ii) the observable price for individual loans traded in the secondary market for loans that will be delivered on a mandatory basis. All of the Company's mortgage interest rate locks are classified as Level II. On May 15, 2014, the Company sold its majority interest in Southern Trust Mortgage. Activity subsequent to the sale is deemed immaterial.
	Mortgage Banking Hedge Instruments
	Mortgage banking hedge instruments are used to mitigate interest rate risk for certain residential mortgage loans held for sale and interest rate locks. These instruments are considered derivatives and are recorded at fair value, based on (i) committed sales prices from investors for commitments to sell mortgage loans or (ii) observable market data inputs for commitments to sell mortgage backed securities. The Company's mortgage banking hedge instruments are classified as Level II. On May 15, 2014, the Company sold its majority interest in Southern Trust Mortgage and on this date, this activity ceased.
	Interest Rate Swaps
	Interest rate swaps are recorded at fair value based on third party vendors who compile prices from various sources and may determine fair value of identical or similar instruments by using pricing models that consider observable market data (Level II).
	Mortgage Servicing Rights
	The Company obtains the fair value of mortgage servicing rights from an independent valuation service. The model used by the independent service to value mortgage servicing rights incorporates inputs and assumptions such as loan characteristics, contractually specified servicing fees, prepayment speeds, delinquency rates, late charges, escrow income, other ancillary revenue, costs to service and other economic factors. Fair value estimates from the model are adjusted for recent market activity, actual experience and, when available, other observable market data (Level II). On May 15, 2014, the Company sold its majority interest in Southern Trust Mortgage and on this date, mortgage servicing rights ceased.

	Measured on nonrecurring basis
The Company may be required, from time to time, to measure and recognize certain other assets at fair value on a nonrecurring basis in accordance with GAAP. The following describes the valuation techniques and inputs used by the Company in determining the fair value of certain assets recorded at fair value on a nonrecurring basis in the financial statements.
Impaired Loans
Loans are designated as impaired when, in the judgment of management based on current information and events, it is probable that all amounts due according to the contractual terms of the loan agreement will not be collected.  The measurement of loss associated with impaired loans can be based on either the observable market price of the loan or the fair value of the collateral.  Fair value is measured based on the value of the collateral securing the loans.  Collateral may be in the form of real estate or business assets including equipment, inventory, and accounts receivable.  The vast majority of the collateral is real estate.  The value of real estate collateral is determined utilizing a market valuation approach based on an appraisal conducted by an independent, licensed appraiser outside of the Company using observable market data (Level II).  However, if the collateral is a house or building in the process of construction or if an appraisal of the real estate property is over two years old, then the fair value is considered Level III.  The value of business equipment is based upon an outside appraisal if deemed significant, or the net book value on the applicable business's financial statements if not considered significant using observable market data.  Likewise, values for inventory and accounts receivables collateral are based on financial statement balances or aging reports (Level III).  Impaired loans allocated to the Allowance for Loan Losses are measured at fair value on a nonrecurring basis. Any fair value adjustments are recorded in the period incurred as provision for loan losses on the consolidated statements of income.
When collateral-dependent loans are performing in accordance with the original terms of their contract, the Company continues to use the appraisal that was performed at origination as the basis for the collateral value. When a loan becomes collateral-dependent and are considered nonperforming, they are reviewed to determine the next appropriate course of action, either foreclosure or modification with forbearance agreement. The loans would then be reappraised prior to foreclosure or before a forbearance agreement is executed. This process does not vary by loan type.
The Company's procedure to monitor the value of collateral for collateral-dependent impaired loans between the receipt of the original appraisal and an updated appraisal is to review annual tax assessment records. At this time, adjustments are made, if necessary. Information considered in the determination not to order an updated appraisal includes the availability and reliability of tax assessment records and significant changes in capitalization rates for income properties. Other facts and circumstances on a case-by-case basis may be considered relative to a decision not to order an updated appraisal. If, in the judgment of management, a reliable collateral value cannot be obtained by an alternative method, an updated appraisal would be obtained.
Circumstances that may warrant a reappraisal for nonperforming loans might include foreclosure proceedings or a material adverse change in the borrower's condition or that of the collateral underlying the loan. In some cases, management may decide that an updated appraisal for a nonperforming loan is not necessary, In such cases, an estimate of the fair value of the collateral would be made by management by reference to current tax assessments, the latest appraised value, and knowledge of collateral value fluctuations in a loan's market area. If, in management's judgment, a reliable collateral value cannot be obtained by an alternative method, an updated appraisal would be obtained.
For the purpose of evaluating the allowance for loan losses, new appraisals are discounted 10% for estimated selling costs when determining the amount of specific reserves. Thereafter, for collateral-dependent impaired loans, we consider each loan on a case-by-case basis to determine whether or not the recorded values are appropriate given current market conditions. When necessary, new appraisals are obtained. If an appraisal is less than 12 months old, the only adjustment made is the 10% discount for selling costs. If an appraisal is older than 12 months, management will use judgment based on knowledge of current market values and specific facts surrounding any particular property to determine if an additional valuation adjustment may be necessary.
Other Real Estate Owned
The value of other real estate owned (“OREO”) is determined utilizing a market valuation approach based on an appraisal conducted by an independent, licensed appraiser using observable market data (Level II).  For other real estate owned properties that may be in construction, the Company’s policy is to obtain “as-is” appraisals on an annual basis as opposed to “as-completed” appraisals.  This approach provides current values without regard to completion of any construction or renovation that may be in process.  Accordingly, the Company considers the valuations to be Level II valuations even though some properties may be in process of renovation or construction. If the collateral value is significantly adjusted due to differences in the comparable properties, or is discounted by the Company because of marketability or other factors, then the fair value is considered Level III. Any initial fair value adjustment is charged against the Allowance for Loan Losses. Any subsequent fair value adjustments are recorded in the period incurred and included in other non-interest expense on the consolidated statements of income.
For the purpose of OREO valuations, appraisals are discounted 10% for selling and holding costs and it is the policy of the Company to obtain annual appraisals for properties held in OREO. Any fair value adjustments are recorded in the period incurred as loss on other real estate owned on the consolidated statements of income.
Repossessed Assets
The value of repossessed assets is determined by the Company based on marketability and other factors and is considered Level III.
The following table summarizes the Company’s non-financial assets that were measured at fair value on a nonrecurring basis during the period.

The fair value of a financial instrument is the current amount that would be exchanged between willing parties, other than in a forced liquidation.  Fair value is best determined based upon quoted market prices.  However, in many instances, there are no quoted market prices for the Company’s various financial instruments.  In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques.  Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows.  Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument.  U.S. generally accepted accounting principles excludes certain financial instruments and all non-financial instruments from its disclosure requirements.  Accordingly, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company.
The following methods and assumptions were used to estimate the fair value of each class of financial instruments (not previously described) for which it is practicable to estimate that value:
Cash and Cash Equivalents
For cash and cash equivalents, the carrying amount is a reasonable estimate of fair value.
Securities held to maturity
Certain debt securities that management has the positive intent and ability to hold until maturity are recorded at amortized cost. Fair values are determined in a manner that is consistent with securities available for sale.
Restricted Securities
The restricted security category is comprised of FHLB and Federal Reserve Bank stock. These stocks are classified as restricted securities because their ownership is restricted to certain types of entities and they lack a market. When the FHLB or Federal Reserve Bank repurchases stock, they repurchase at the stock's book value. Therefore, the carrying amounts of restricted securities approximate fair value.
Loans, Net
For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values.  For fixed rate loans, the fair value is estimated by discounting future cash flows using current market inputs at which loans with similar terms and qualities would be made to borrowers of similar credit quality.  Where quoted market prices were available, primarily for certain residential mortgage loans, such market rates were utilized as estimates for fair value. Fair value for impaired loans is described above.
Bank Owned Life Insurance
The carrying amount of bank owned life insurance is a reasonable estimate of fair value.
Accrued Interest Receivable and Payable
The carrying amounts of accrued interest approximate fair values.
Deposits
The fair value of demand deposits, savings accounts, and certain money market deposits is the amount payable on demand at the reporting date.  For all other deposits, the fair value is determined using the discounted cash flow method.  The discount rate is equal to the rate currently offered on similar products.
Securities Sold Under Agreements to Repurchase and Short-Term  Debt
The carrying amounts approximate fair values.
FHLB Borrowings and Subordinated Debt
For variable rate long-term debt, fair values are based on carrying values.  For fixed rate debt, fair values are estimated based on observable market prices and discounted cash flow analysis using interest rates for borrowings of similar remaining maturities and characteristics.  The fair values of the Company's Subordinated Debentures are estimated using discounted cash flow analysis based on the Company's current incremental borrowing rates for similar types of borrowing arrangements.
Off-Balance Sheet Financial Instruments
The fair value of commitments to extend credit is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties.  For fixed-rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates.  The fair value of standby letters of credit is based on fees currently charged for similar agreements or on the estimated cost to terminate them or otherwise settle the obligations with the counterparties at the reporting date.  At December 31, 2014 and 2013, the fair values of loan commitments and standby letters of credit were deemed immaterial; therefore, they have not been included in the tables below.

The Company assumes interest rate risk as a result of its normal operations.  As a result, the fair values of the Company's financial instruments will change when interest rate levels change, which may be either favorable or unfavorable to the Company.  Management attempts to match maturities of assets and liabilities to the extent believed necessary to minimize interest rate risk.  However, borrowers with fixed rate obligations are less likely to prepay in a rising rate environment and more likely to prepay in a falling rate environment.  Conversely, depositors who are receiving fixed rates are more likely to withdraw funds before maturity in a rising rate environment and less likely to do so in a falling rate environment.  Management monitors rates and maturities of assets and liabilities and attempts to minimize interest rate risk by adjusting terms of new loans and deposits and by investing in securities with terms that mitigate the Company's overall interest rate risk.

Regulatory Capital Requirements [Abstract]
Capital Requirements	Capital Requirements
	The Company, on a consolidated basis, and Middleburg 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 and Bank’s financial statements.  Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and Middleburg Bank must meet specific capital guidelines that involve quantitative measures of the Company's and Middleburg Bank’s 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 weightings, and other factors.  Prompt corrective action provisions are not applicable to bank holding companies.
	Quantitative measures established by regulation to ensure capital adequacy require the Company and Middleburg Bank to maintain minimum amounts and ratios (set forth in the table below) of total and Tier 1 capital to risk-weighted assets, and of Tier 1 capital to average assets.  Management believes, as of December 31, 2014 and 2013, that the Company and Middleburg Bank meet all capital adequacy requirements to which they are subject.
	As of December 31, 2014, the most recent notification from the Federal Reserve Bank categorized Middleburg Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, an institution must maintain minimum total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the table.  There are no conditions or events since that notification that management believes have changed the institution's category.
	The Company’s and Middleburg Bank’s actual capital amounts and ratios are also presented in the following table.
		Actual			Minimum Capital Requirement			Minimum To Be Well Capitalized Under Prompt Corrective Action Provisions

	As of December 31, 2014, goodwill and intangible assets relate to the Company’s acquisition of Middleburg Trust Company and Middleburg Investment Advisors. On May 15, 2014, the Company sold all of its majority interest in Southern Trust Mortgage and on this date the related goodwill was eliminated. As of December 31, 2013, goodwill and intangible assets relate to the Company’s acquisition of Middleburg Trust Company and Middleburg Investment Advisors and the consolidation of Southern Trust Mortgage.
	Goodwill is not amortized and the Company is no longer required to perform a test for impairment unless, based on an assessment of qualitative factors related to goodwill, the Company determines that it is more likely than not that the fair value is less than its carrying amount. If the likelihood of impairment is more than 50%, the Company must perform a test for impairment and may be required to record impairment charges.
	As of December 31, 2013, the Company recorded a $500,000 goodwill impairment charge related to Southern Trust Mortgage which is reflected on the consolidated statements of income for 2013.  Identifiable intangible assets are being amortized over the period of expected benefit, which is 15 years.

	On December 12, 2003, MFC Capital Trust II, a wholly owned subsidiary of the Company, was formed for the purpose of issuing redeemable Capital Securities.  On December 19, 2003, $5.0 million of trust-preferred securities were issued through a pooled underwriting totaling approximately $344 million.  The securities have a LIBOR-indexed floating rate of interest.
	During 2014, the interest rates ranged from 3.07% to 3.09%.  For the year ended December 31, 2014, the weighted-average interest rate was 3.08%.  The securities have a mandatory redemption date of January 23, 2034, and are subject to varying call provisions beginning January 23, 2009. The principal asset of the trust is $5.2 million of the Company’s junior subordinated debt securities with like maturities and like interest rates to the Capital Securities.  See Note 24 for information regarding an interest rate swap entered into by the Company to manage the cash flows associated with these trust preferred securities.
	The trust-preferred securities may be included in Tier 1 capital for regulatory capital adequacy determination purposes up to 25% of Tier 1 Capital after its inclusion.  The portion of the trust-preferred securities not considered as Tier 1 Capital may be included in Tier 2 Capital.  On December 31, 2014, all of the Company’s trust-preferred securities are included in Tier I Capital.
	The obligations of the Company with respect to the issuance of the Capital Securities constitute a full and unconditional guarantee by the Company of the trusts’ obligations with respect to the Capital Securities.
	Subject to certain exceptions and limitations, the Company may elect from time to time to defer interest payments on the junior subordinated debt securities, which would result in a deferral of distribution payments on the related Capital Securities. There were no deferred interest payments on our junior subordinated debt securities at December 31, 2014, 2013 and 2012.

Segment Reporting	Segment Reporting
	The Company operates in a decentralized fashion in the following principal business activities: retail banking services; wealth management services; and mortgage banking services.
	•	Revenue from retail banking activity consists primarily of interest earned on loans and investment securities and service charges on deposit accounts.
	•	Revenue from the wealth management activities is comprised of fees based upon the market value of the accounts under administration as well as commissions on investment transactions.
	•	Revenue from the mortgage banking activities is comprised of interest earned on loans and fees received as a result of the mortgage origination process through the Company's affiliation with Southern Trust Mortgage. The Company recognized gains on the sale of loans as part of other income. On May 15, 2014, the Company sold all of its majority interest in Southern Trust Mortgage and as a result, any mortgage banking activity for the Company subsequent to the sale date is included with the results of the retail banking segment. Any activity since the sale of Southern Trust Mortgage is considered to be immaterial and incidental to the Company's retail banking activities. The mortgage banking activities will continue to be evaluated and will be separately reported as a distinguishable segment if determined to be of significance to the reader of these financial statements or if the related operating results are believed to meet the quantitative tests for disclosure. Mortgage banking activities for the twelve months ended December 31, 2014 are the result of Southern Trust Mortgage activity that was consolidated with the Company through the date of sale.
	Middleburg Bank and the Company have assets in custody with Middleburg Trust Company and accordingly pay Middleburg Trust Company a monthly fee. Middleburg Bank also pays interest to Middleburg Trust Company on deposit accounts with Middleburg Bank. Middleburg Bank provides a warehouse line and office space, data processing and accounting services to Southern Trust Mortgage for which it received income. Transactions related to these relationships are eliminated to reach consolidated totals.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives
	The Company utilizes derivative instruments as a part of its asset-liability management program to control fluctuation of market values and cash flows to changes in interest rates associated with certain financial instruments. The Company accounts for derivatives in accordance with ASC 815, "Derivatives and Hedging". Under current guidance, derivative transactions are classified as either cash flow hedges or fair value hedges or they are not designated as hedging instruments. The Company designates each derivative instrument at the inception of the derivative transaction in accordance with this guidance. Information concerning each of the Company's categories of derivatives as of December 31, 2014 and 2013 is presented below.
	Derivatives designated as cash flow hedges
	During 2010, the Company entered into an interest rate swap agreement as part of the interest rate risk management process.  The swap was designated as a cash flow hedge intended to hedge the variability of cash flows associated with the Company’s trust preferred capital securities described in Note 19, “Subordinated Notes”.  The swap hedges the cash flow associated with the trust preferred capital notes wherein the Company receives a floating rate based on LIBOR from a counterparty and pays a fixed rate of 2.59% to the same counterparty.  The swap is calculated on a notional amount of $5.2 million.  The term of the swap is 10 years and commenced on October 23, 2010.  The swap was entered into with a counterparty that met the Company’s credit standards and the agreement contains collateral provisions protecting the at-risk party.  The Company believes that the credit risk inherent in the contract is not significant.
	During 2013, the Company entered into an interest rate swap agreement as part of the interest rate risk management process.  The swap has been designated as a cash flow hedge intended to hedge the variability of cash flows associated with the Company’s FHLB borrowings described in Note 7, “Borrowings”.  The swap hedges the cash flows associated with the FHLB borrowings wherein the Company receives a floating rate based on LIBOR from a counterparty and pays a fixed rate of 1.43% to the same counterparty.  The swap is calculated on a notional amount of $10 million.  The term of the swap is 5 years and commenced on November 25, 2013.  The swap was entered into with a counterparty that met the Company’s credit standards and the agreement contains collateral provisions protecting the at-risk party.  The Company believes that the credit risk inherent in the contract is not significant.
	Amounts receivable or payable are recognized as accrued under the terms of the agreement, with the effective portion of the derivative’s unrealized gain or loss recorded as a component of other comprehensive income.  The ineffective portion of the unrealized gain or loss, if any, would be recorded in other income or other expense.  The Company has assessed the effectiveness of the hedging relationship by comparing the changes in cash flows on the designated hedged item.  As a result of this assessment, hedge ineffectiveness for this interest rate swap of $6,000 was identified during 2014 and is classified as other operating expenses on the consolidated statements of income.
	The amounts included in accumulated other comprehensive income (loss) as unrealized losses (market value net of tax) were $185,000 and $29,000 as of December 31, 2014 and 2013, respectively.
	Information concerning the derivative designated as a cash flow hedge at December 31, 2014 and 2013 is presented in the following tables:

	Derivatives designated as fair value hedges
	The Company will from time to time utilize derivatives to limit exposure to the variability of fair market values of certain financial instruments. Information below is presented on derivatives designated as fair value hedges as of December 31, 2014 and 2013.
	Mortgage banking activities
	As a result of the Company's affiliation with Southern Trust Mortgage, and as part of the related mortgage banking activities, Southern Trust Mortgage entered 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 the interest rate. The period of time between the origination of a loan commitment and closing and sale of the loan generally ranges from 60 to 120 days. Southern Trust Mortgage either locked the loan and associated rate in with an investor and committed to deliver the loan only if settlement occurs ("best efforts delivery") or it committed to deliver the locked loan in a binding ("mandatory") delivery program with an investor. Because of the high correlation between best efforts delivery contracts and interest rate lock commitments, no gain or loss was recognized on best efforts contracts and any resulting interest rate risk associated with these transactions was borne by the ultimate purchaser of the loan. Accordingly, as of December 31, 2013, the Company did not designate best efforts delivery contracts and the related interest rate lock commitments as hedging instruments (See discussion below under "Derivatives not designated as hedging instruments"). On May 15, 2014, the Company sold all of its majority interest in Southern Trust Mortgage and as a result, on this date, this activity ceased.
	Mandatory delivery of mortgage loans
	For the portion of interest rate lock commitments that were designated to be delivered under a mandatory delivery method, the Company, through its affiliation with Southern Trust Mortgage, bore the risk of changes in value of the commitment from the time a rate was locked with the mortgage customer until a loan was closed and ultimately sold to an investor. To mitigate this risk, the Company entered into forward sales contracts of mortgage backed securities ("MBS") with similar characteristics to the rate lock commitments. Both the rate lock commitments and the associated forward sales contracts were designated as fair value hedges by the Company as of December 31, 2013. On May 15, 2014, the Company sold all of its ownership interest in Southern Trust Mortgage and as a result, on this date, this activity ceased. Until the sate of sale, rate lock commitments and forward sales contracts of MBS were recorded at fair value with changes in fair value recorded through non-interest income on the consolidated statements of income.
	The notional amount of interest rate lock commitments related to mandatory delivery methods totaled $22.2 million at December 31, 2013. This represented a total of 110 open interest rate lock commitments under mandatory delivery at December 31, 2013. The fair value of the open interest rate lock commitments under mandatory delivery at December 31, 2013 were $16,000.
	At December 31, 2013, Southern Trust Mortgage had 27 open forward sales contracts of MBS with a notional value of $33.0 million. The fair value of these open forward sales contracts was $202,000 at December 31, 2013. Certain additional risks could arise from these forward delivery contracts in that the counterparties to the contracts may not be able to meet the terms of the contracts. At December 31, 2013, we did not expect any counterparty to fail to meet its obligations. Additional risks inherent in mandatory delivery programs include the risk that if Southern Trust Mortgage did not close the loans subject to interest rate lock commitments, they would be obligated to deliver MBS to the counterparty under the forward sales agreement. If this would have been required, Southern Trust Mortgage could have incurred significant costs in acquiring replacement loans or MBS. On May 15, 2014, the Company sold all of its majority interest in Southern Trust Mortgage and as a result, on this date, this activity ceased.
	Derivatives not designated as hedging instruments
	Best efforts delivery mortgage banking derivatives
	Interest rate lock commitments under best efforts delivery and the resulting commitments to deliver loans to investors on a best efforts basis are considered derivatives. For loans to be delivered under a best efforts delivery method, the Company mitigates any risk from changes in interest rates through the use of best effort forward delivery commitments, whereby the Company commits to sell a loan at the time the borrower commits to an interest rate with the intent that the investor has assumed interest rate risk on the loan.  As a result, the Company is not exposed to losses nor will it realize gains related to its rate lock commitments due to changes in interest rates.  The correlation between the rate lock commitment and the best efforts contracts is very high.
	As of December 31, 2013, the notional amount of open best efforts interest rate lock commitments was $103.5 million. The related notional amounts of open forward sales commitments to investors as of December 31, 2013 was $114.4 million.
	The market value of best effort rate lock commitments and best efforts forward delivery contracts is not readily ascertainable with
	precision because the rate lock commitments and best efforts contracts are not actively traded in stand-alone markets.  Because of the high correlation between rate lock commitments and best efforts contracts, no gain or loss occurs on the rate lock commitments.
	Since the time between when a loan is locked under a best efforts contract and delivery of that loan to an investor is short, and the investor has committed to purchase the loan at an agreed-upon price, if it settles, we have concluded that the difference between the fair value of the loans and the fair value of the best efforts commitments was not material.
	On May 15, 2014, the Company sold all of its majority interest in Southern Trust Mortgage and as a result, on this date, this activity ceased.
	Two-way client loan swaps
	During the fourth quarter of 2014 and 2012, the Company entered into certain interest rate swap contracts that are not designated as hedging instruments. These derivative contracts relate to transactions in which we enter into an interest rate swap with a customer while at the same time entering into an offsetting interest rate swap with another financial institution. In connection with each swap transaction, the Company agrees to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on an identical notional amount at a fixed interest rate. At the same time, the Company agrees to pay the counterparty the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. The transaction allows our clients to effectively convert a variable rate loan into a fixed rate loan. Because the Company acts as an intermediary for our customers, changes in the fair value of the underlying derivatives contracts offset each other and do not significantly impact our results of operations. The Company had no undesignated interest rate swaps at December 31, 2014 and December 31, 2013.
	Certain additional risks arise from interest rate swap contracts in that the counterparties to the contracts may not be able to meet the terms of the contracts. We do not expect any counterparty to fail to meet its obligations.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principles of Consolidation	Principles of Consolidation
	The consolidated financial statements of Middleburg Financial Corporation and its wholly owned subsidiaries, Middleburg Bank, Middleburg Investment Group, Inc., Middleburg Trust Company and Middleburg Bank Service Corporation include the accounts of all companies.  Through May 15, 2014, the Company owned 62.3% of the issued and outstanding membership interest units of Southern Trust Mortgage, through its subsidiary, Middleburg Bank. The issued and outstanding interest of Southern Trust Mortgage not held by the Company is reported as Non-Controlling Interest in Consolidated Subsidiary.  Accounting Standards Codification Topic 810, Consolidation, requires that the Company no longer eliminate through consolidation the equity investment in MFC Capital Trust II, which approximated $155,000 for each of the years ended December 31, 2014 and 2013.  The subordinate debt of the trust preferred entity is reflected as a liability of the Company.  All material intercompany balances and transactions have been eliminated in consolidation.
Securities	Securities
	Certain debt securities that management has the positive intent and ability to hold until maturity are classified as "held-to-maturity" and recorded at amortized cost. Securities not classified as held-to-maturity, including equity securities with readily determinable fair values, are classified as "available-for-sale" and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income (loss). Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method.
	Equity investments in the FHLB and the Federal Reserve Bank of Richmond are separately classified as restricted securities and are carried at cost.
	Impairment of securities occurs when the fair value of a security is less than its amortized cost.  For debt securities, impairment is considered other-than-temporary and recognized in its entirety in net income if either (i) the intent is to sell the security or (ii) it is more likely than not that it will be necessary to sell the security prior to recovery of its amortized cost.  If, however, management’s intent is not to sell the security and it is not more than likely that management will be required to sell the security before recovery, management must determine what portion of the impairment is attributable to credit loss, which occurs when the amortized cost of the security exceeds the present value of the cash flows expected to be collected from the security.  If there is no credit loss, there is no other-than-temporary impairment.  If there is a credit loss, other-than-temporary impairment exists and the credit loss must be recognized in net income and the remaining portion of impairment must be recognized in other comprehensive income (loss).
	For equity securities carried at cost as restricted securities, impairment is considered to be other-than-temporary based on our ability and intent to hold the investment until a recovery of fair value.  Other-than-temporary impairment of an equity security results in a write-down that must be included in income.  We regularly review each security for other-than-temporary impairment based on criteria that include the extent to which cost exceeds market price, the duration of that market decline, the financial health of and specific prospects for the issuer, our best estimate of the present value of cash flows expected to be collected from debt securities, the intention with regards to holding the security to maturity and the likelihood that we would be required to sell the security before recovery.
Loans	Loans
	The Company grants mortgage, commercial, and consumer loans to clients.  The loan portfolio is segmented into commercial loans, real estate loans, and consumer loans.  Real estate loans are further divided into the following classes:  construction; farmland; 1-4 family residential; and other real estate loans.  Descriptions of the Company’s loan classes are as follows:
	Commercial Loans: Commercial loans are typically secured with non-real estate commercial property.  The Company makes commercial loans primarily to middle market businesses located within our market area.
	Real Estate Loans – Construction: The Company originates construction loans for the acquisition and development of land and construction of condominiums, townhomes, and 1-4 family residences. This class also includes acquisition, development and construction loans for retail and other commercial purposes, primarily in our market areas.
	Real Estate Loans- Farmland:  Loans secured by agricultural property and not included in Real Estate – Other.
	Real Estate Loans – 1-4 Family:  This class of loans includes loans secured by 1-4 family homes.  The Company’s general practice is to sell the majority of its newly originated fixed-rate residential real estate loans in the secondary mortgage market, and to hold in its portfolio adjustable rate residential real estate loans and loans in close proximity to its financial service centers.
	Real Estate Loans – Other: This loan class consists primarily of loans secured by multi-unit residential property and owner and non-owner occupied commercial and industrial property.  This class also includes loans secured by real estate which do not fall into other classifications.
	Consumer Loans: Consumer loans include all loans made to individuals for consumer or personal purposes.  They include new and used auto loans, unsecured loans, lines of credit and home equity loans and lines of credit.
	The ability of the debtors to honor their contracts is dependent upon the real estate and general economic conditions in this area.
	For all classes of loans, the Company considers loans to be past due when a payment is not received by the payment due date according to the contractual terms of the loan.  The Company monitors past due loans according to the following categories: less than 30 days past due, 30 – 59 days past due, 60 – 89 days past due, and 90 days or greater past due. The accrual of interest on all classes of loans is discontinued at the time the loans are 90 days delinquent unless they are well-secured and in the process of collection.
	Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off generally are reported at their outstanding unpaid principal balances adjusted for charge-offs, the allowance for loan losses, and any deferred fees or costs on originated loans.  Deferred fees and costs include discounts and premiums on syndicated and guaranteed loans purchased. Interest income is accrued on the unpaid principal balance.  Loan origination and commitment fees, net of certain direct loan origination costs, are deferred and recognized as an adjustment of the loan yield over the life of the related loan.
	All interest accrued but not collected for loans that are placed on nonaccrual or charged-off is reversed against interest income.  The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual.  Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Allowance for Loan Losses	Allowance for Loan Losses
	The allowance for loan losses reflects management’s judgment of probable loan losses inherent in the portfolio at the balance sheet date.  Management uses a disciplined process and methodology to establish the allowance for losses each quarter.  To determine the total allowance for loan losses, the Company estimates the reserves needed for each segment of the portfolio, including loans analyzed individually and loans analyzed on a pooled basis.  The allowance for loan losses consists of amounts applicable to:  (i) the commercial loan portfolio; (ii) the real estate portfolio; and (iii) the consumer loan portfolio.
	To determine the allowance for loan losses, loans are pooled by portfolio segment and losses are modeled using historical experience, and quantitative and other mathematical techniques over the loss emergence period.  Each class of loan requires exercising significant judgment to determine the estimation that fits the credit risk characteristics of its portfolio segment.  The Company uses internally developed models in this process.  Management must use judgment in establishing additional input metrics for the modeling processes.  The models and assumptions used to determine the allowance are reviewed to ensure that their theoretical foundation, assumptions, data integrity, computational processes, reporting practices, and end user controls are appropriate and properly documented.
	The establishment of the allowance for loan losses relies on a consistent process that requires multiple layers of management review and judgment and responds to changes in economic conditions, customer behavior, and collateral value, among other influences.  From time to time, events or economic factors may affect the loan portfolio, causing management to provide additional amounts to or release balances from the allowance for loan losses.  Qualitative factors considered in the allowance for loan losses evaluation include the levels and trends in delinquencies and nonperforming loans, trends in volume and terms of loans, the effects of any changes in lending policies, the experience, ability, and depth of management, national and local economic trends and conditions, concentrations of credit, the quality of the Company’s loan review system, competition and regulatory requirements.  The Company’s allowance for loan losses is sensitive to risk ratings and economic assumptions and delinquency trends driving statistically modeled reserves.  Individual loan risk ratings are evaluated based on each situation by experienced senior credit officers.
	Management monitors differences between estimated and actual incurred loan losses.  This monitoring process includes periodic assessments by senior management of loan portfolios and the models used to estimate incurred losses in those portfolios.  Additions to the allowance for loan losses are made by charges to the provision for loan losses.  Credit exposures deemed to be uncollectible are charged against the allowance for loan losses.  Recoveries of previously charged-off amounts are credited to the allowance for loans losses.
Loan Charge-off Policies	Loan Charge-off Policies
	Commercial and consumer loans are generally charged off when:
	•they are 90 days past due;
	•the collateral is repossessed; or
	•the borrower has filed bankruptcy.
	All classes of real estate loans are charged down to the net realizable value when the Company determines that the sole source of repayment is liquidation of the collateral.
Impaired Loans	Impaired Loans
	For all classes of loans, a loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement.  Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due.  Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired.  Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed.
	For all classes of loans, impairment is measured on a loan-by-loan basis by comparing the loan balance to either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent. Any variance in values is charged-off when determined.
Troubled Debt Restructurings	Troubled Debt Restructurings
	In situations where, for economic or legal reasons related to a borrower’s financial condition, management may grant a concession to the borrower that it would not otherwise consider, the related loan is classified as a troubled debt restructuring (“TDR”).  Management strives to identify borrowers in financial difficulty early and works with them to modify their loan to more affordable terms before their loan reaches nonaccrual status.  These modified terms may include rate reductions, principal forgiveness, payment forbearance and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of the collateral.  In cases where borrowers are granted new terms that provide for a reduction of either interest or principal, management measures any impairment on the restructuring as noted above for impaired loans. All identified TDRs are considered to be impaired loans.
	Management considers troubled debt restructurings and subsequent defaults in restructured loans in the determination of the adequacy of the Company's allowance for loan losses. When identified as a TDR, a loan is evaluated for potential loss as noted above for impaired loans. Loans identified as TDRs frequently are on nonaccrual status at the time of the restructuring and, in some cases, partial charge-offs may have already been taken against the loan and a specific allowance may have already been established for the loan. As a result of any modification as a TDR, the specific reserve associated with the loan may be increased. Additionally, loans modified in a TDR are closely monitored for delinquency as an early indicator of possible future defaults. If loans modified in a TDR subsequently default, the Company evaluates them for possible further impairment. As a result, any specific allowance may be increased, adjustments may be made in the allocation of the total allowance balance, or partial charge-offs may be taken to further write-down the carrying value of the loan. Management exercises significant judgment in developing estimates for potential losses associated with TDRs.
Mortgage Loans Held for Sale	Mortgage Loans Held for Sale
	Mortgage loans held for sale are carried at the lower of aggregate cost or fair value. The fair value of mortgage loans held for sale is determined using current secondary market prices for loans with similar coupons, maturities, and credit quality and fair value of loans committed at year-end. There has been no significant activity since May 15, 2014, the date the Company sold its majority interest in Southern Trust Mortgage, and therefore, there were no loans held for sale on the consolidated balance sheet as of December 31, 2014.
Premises and Equipment	Premises and Equipment
	Land is carried at cost.  Premises and equipment are stated at cost less accumulated depreciation.  Depreciation of property and equipment is computed principally on the straight-line method over the following estimated useful lives:
		Years
	Buildings and improvements	Oct-40
	Furniture and equipment	15-Mar
	Maintenance and repairs of property and equipment are charged to operations and major improvements are capitalized.  Upon retirement, sale, or other disposition of property and equipment, the cost and accumulated depreciation are eliminated from the accounts and gain or loss is included in income.
Other Real Estate Owned	Other Real Estate Owned and Repossessed Assets
Goodwill and Intangible Assets	Goodwill and Intangible Assets
	With the adoption of Accounting Standards Update (ASU) 2011-08, "Intangible-Goodwill and Other-Testing Goodwill for Impairment", the Company is no longer required to perform a test for impairment unless, based on an assessment of qualitative factors related to goodwill, the Company determines that it is more likely than not that the fair value is less than its carrying amount. If the likelihood of impairment is more than 50%, the Company must perform a test for impairment and may be required to record impairment charges.
	Additionally, acquired intangible assets (customer relationships) are separately recognized and amortized over their useful life of 15 years.
Bank-Owned Life Insurance	Bank-Owned Life Insurance
	The Company owns insurance on the lives of a certain group of key employees. The policies were purchased to help offset the increase in the costs of various fringe benefit plans, including healthcare. The cash surrender value of these policies is included as an asset on the consolidated balance sheets, and any increase in cash surrender value is recorded as non-interest income on the consolidated statements of income. In the event of the death of an insured individual under these policies, the Company would receive a death benefit which would be recorded as other income.
Income Taxes	Income Taxes
	Deferred income tax assets and liabilities are determined using the balance sheet method. Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws.
	When tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained.  The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any.  Tax positions taken are not offset or aggregated with other positions.  Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50% likely of being realized upon settlement with the applicable taxing authority.  The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits in the accompanying consolidated balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination.  Interest and penalties associated with unrecognized tax benefits are classified as additional income taxes in the consolidated statements of income. No liabilities for unrecognized tax benefits have been recognized as of December 31, 2014 or 2013.
Trust Company Assets	Trust Company Assets
	Securities and other properties held by Middleburg Trust Company in a fiduciary or agency capacity are not assets of the Company and are not included in the accompanying consolidated financial statements.
Earnings Per Share	Earnings Per Share
	Basic earnings per share represents income available to common shareholders divided by the weighted-average number of common shares outstanding during the period.  Nonvested restricted shares are included in basic earnings per share because of dividend participation rights. Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance.  Potential common shares that may be issued by the Company relate solely to outstanding stock options and the warrant, and are determined using the treasury stock method.
Cash and Cash Equivalents	Cash and Cash Equivalents
	For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from other banks and federal funds sold. Generally, federal funds are sold and purchased for one-day periods.
Use of Estimates	Use of Estimates
	The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.  Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, impairment of goodwill and intangible assets, valuation of other real estate owned, and other-than-temporary impairment of securities.
Advertising Costs	Advertising Costs
	The Company follows the policy of charging the costs of advertising to expense as incurred.
Comprehensive Income (Loss)	Comprehensive Income (Loss)
	Accounting principles generally require that recognized revenue, expenses, gains, and losses be included in net income.  Although certain changes in assets and liabilities, such as unrealized gains and losses on available for sale securities, and changes in the fair value of interest rate swaps, are reported as a separate component of the equity section of the consolidated balance sheets, such items, along with net income, are components of comprehensive income (loss).
Securities Sold Under Agreements to Repurchase	Securities Sold Under Agreements to Repurchase
	Securities sold under agreements to repurchase are reflected at the amount of cash received in connection with the transaction.  The Company does not account for repurchase agreement transactions as sales.  All repurchase agreement transactions entered into by the Company are accounted for as collateralized financings. The Company may be required to provide additional collateral based on the fair value of the underlying securities.
Derivative Financial Instruments	Derivative Financial Instruments
	The Company utilizes derivative financial instruments as a part of its asset-liability management program to control exposure to interest rate changes and fluctuations in market values and cash flows associated with certain financial instruments. The Company accounts for derivatives in accordance with ASC 815, "Derivatives and Hedging". Under current guidance, derivative transactions are classified as either cash flow hedges or fair value hedges or they are not designated as hedging instruments. The Company designates each transaction at its inception.
	The Company documents all relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking various hedge transactions.  This process includes linking all derivatives that are designated as fair value hedges or cash flow hedges to specific assets or liabilities on the balance sheet.  The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are effective in offsetting changes in fair values or cash flows of hedged items.
	As of December 31, 2014, the Company had both fair value and cash flow hedges on its balance sheet as well as derivative financial instruments that have not been designated as hedging instruments.  The derivatives are reported at fair value as of each balance sheet date. For designated cash flow hedges, the effective portions of changes in the fair value of the derivative are recorded in other comprehensive income (loss) and are recognized in the income statement when the hedged item affects earnings.  Ineffective portions of changes in the fair value of cash flow hedges are recognized in earnings as are changes in market value of derivatives not designated as hedging instruments.
	Information concerning each of the Company's categories of derivatives as of December 31, 2014 and 2013 is presented in Note 24 to the consolidated financial statements.
Reclassifications	Reclassifications
	Certain reclassifications have been made to prior period balances to conform to current year presentation. No reclassifications were significant and had no effect on net income.

	Transfers of financial assets are accounted for as sales when control over the assets has been surrendered.  Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Share-Based Employee Compensation Plan	Share-Based Employee Compensation Plan
	At December 31, 2014, the Company had a share-based employee compensation plan which is described more fully in Note 8 to the consolidated financial statements. Compensation cost relating to share-based payment transactions is recognized in the consolidated financial statements.  That cost is measured based on the fair value of the equity instruments issued and recognized over the applicable vesting period.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In January 2014, the FASB issued ASU 2014-01, “Investments-Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects (a consensus of the FASB Emerging Issues Task Force).” The amendments in this ASU permit 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 recognizes the net investment performance in the income statement as a component of income tax expense (benefit). The amendments in this ASU should be applied retrospectively to all periods presented. A reporting entity that uses the effective yield method to account for its investments in qualified affordable housing projects before the date of adoption may continue to apply the effective yield method for those preexisting investments. The amendments in this ASU are effective for annual periods and interim reporting periods within those annual periods, beginning after December 15, 2014. Early adoption is permitted. The Company is currently assessing the impact that ASU 2014-01 will have on its consolidated financial statements.
	In January 2014, the FASB issued ASU 2014-04, “Receivables-Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure (a consensus of the FASB Emerging Issues Task Force).” The amendments in this ASU clarify 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, the amendments require 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. The amendments in this ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. The Company is currently assessing the impact that ASU 2014-04 will have on its consolidated financial statements.
	In April 2014, the FASB issued ASU 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” The amendments in this ASU change the criteria for reporting discontinued operations while enhancing disclosures in this area. Under the new guidance, only disposals representing a strategic shift in operations should be presented as discontinued operations. Those strategic shifts should have a major effect on the organization’s operations and financial results and include disposals of a major geographic area, a major line of business, or a major equity method investment. The new guidance requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. Additionally, the new guidance requires disclosure of the pre-tax income attributable to a disposal of a significant part of an organization that does not qualify for discontinued operations reporting. The amendments in the ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. Early adoption is permitted. The Company does not expect the adoption of ASU 2014-08 to have a material impact on its consolidated financial statements.
	In June 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers: Topic 606.” This ASU applies to any entity using U.S. GAAP that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards. The guidance supersedes the revenue recognition requirements in Topic 605, “Revenue Recognition,, most industry-specific guidance, and some cost guidance included in Subtopic 605-35, “Revenue Recognition-Construction-Type and Production-Type Contracts.” The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To be in alignment with the core principle, an entity must apply a five step process including: identification of the contract(s) with a customer, identification of performance obligations in the contract(s), determination of the transaction price, allocation of the transaction price to the performance obligations, and recognition of revenue when (or as) the entity satisfies a performance obligation. Additionally, the existing requirements for the recognition of a gain or loss on the transfer of nonfinancial assets that are not in a contract with a customer have also been amended to be consistent with the guidance on recognition and measurement. The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted. The Company is currently assessing the impact that ASU 2014-09 will have on its consolidated financial statements.
	In June 2014, the FASB issued ASU 2014-10, “Development Stage Entities (Topic 915): Elimination of Certain Financial Reporting Requirements, Including an Amendment to Variable Interest Entities Guidance in Topic 810, Consolidation.” The amendments in this ASU remove all incremental financial reporting requirements from U.S. GAAP for development stage entities, including the removal of Topic 915, “Development Stage Entities,” from the FASB Accounting Standards Codification. In addition, this ASU adds an example disclosure and removes an exception provided to development stage entities in Topic 810, “Consolidation,” for determining whether an entity is a variable interest entity. The presentation and disclosure requirements in Topic 915 will no longer be required for the first annual period beginning after December 15, 2014. The revised consolidation standards are effective for annual periods beginning after December 15, 2015. Early adoption is permitted. The Company does not expect the adoption of ASU 2014-10 to have a material impact on its consolidated financial statements.
	In June 2014, the FASB issued ASU No. 2014-11, “Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures.” This ASU aligns the accounting for repurchase-to-maturity transactions and repurchase agreements executed as a repurchase financing with the accounting for other typical repurchase agreements. The new guidance eliminates sale accounting for repurchase-to-maturity transactions and supersedes the guidance under which a transfer of a financial asset and a contemporaneous repurchase financing could be accounted for on a combined basis as a forward agreement. The amendments in the ASU also require a new disclosure for transactions economically similar to repurchase agreements in which the transferor retains substantially all of the exposure to the economic return on the transferred financial assets throughout the term of the transaction. Additional disclosures will be required for the nature of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings. The amendments in this ASU are effective for the first interim or annual period beginning after December 15, 2014; however, the disclosure for transactions accounted for as secured borrowings is required to be presented for annual periods beginning after December 15, 2014, and interim periods beginning after March 15, 2015. Early adoption is not permitted. The Company is currently assessing the impact that ASU 2014-11 will have on its consolidated financial statements.
	In June 2014, the FASB issued ASU No. 2014-12, “Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period.” The new guidance applies to reporting entities that grant employees share-based payments in which the terms of the award allow a performance target to be achieved after the requisite service period. The amendments in the ASU require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. Existing guidance in “Compensation - Stock Compensation (Topic 718),” should be applied to account for these types of awards. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted and reporting entities may choose to apply the amendments in the ASU either on a prospective or retrospective basis. The Company is currently assessing the impact that ASU 2014-12 will have on its consolidated financial statements.
	In August 2014, the FASB issued ASU No. 2014-14, “Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40): Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure.” The amendments in this ASU apply to creditors that hold government-guaranteed mortgage loans and are intended to eliminate the diversity in practice related to the classification of these guaranteed loans upon foreclosure. The new guidance stipulates that a mortgage loan be derecognized and a separate other receivable be recognized upon foreclosure if (1) the loan has a government guarantee that is not separable from the loan prior to foreclosure, (2) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim, and (3) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclosure, the other receivable should be measured on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2014. Entities may adopt the amendments on a prospective basis or modified retrospective basis as of the beginning of the annual period of adoption; however, the entity must apply the same method of transition as elected under ASU 2014-04. Early adoption is permitted provided the entity has already adopted ASU 2014-04. The Company is currently assessing the impact that ASU 2014-14 will have on its consolidated financial statements.
	In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” This update is intended to provide guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. Management is required under the new guidance to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date the financial statements are issued when preparing financial statements for each interim and annual reporting period. If conditions or events are identified, the ASU specifies the process that must be followed by management and also clarifies the timing and content of going concern footnote disclosures in order to reduce diversity in practice. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2016. Early adoption is permitted. The Company does not expect the adoption of ASU 2014-15 to have a material impact on its consolidated financial statements.
	In November 2014, the FASB issued ASU No. 2014-16, “Derivatives and Hedging (Topic 815): Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share Is More Akin to Debt or to Equity.” The amendments in ASU do not change the current criteria in U.S. GAAP for determining when separation of certain embedded derivative features in a hybrid financial instrument is required. The amendments clarify how current U.S. GAAP should be interpreted in evaluating the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share. Specifically, the amendments clarify that an entity should consider all relevant terms and features, including the embedded derivative feature being evaluated for bifurcation, in evaluating the nature of the host contract. Furthermore, the amendments clarify that no single term or feature would necessarily determine the economic characteristics and risks of the host contract. Rather, the nature of the host contract depends upon the economic characteristics and risks of the entire hybrid financial instrument. The amendments in this ASU also clarify that, in evaluating the nature of a host contract, an entity should assess the substance of the relevant terms and features (i.e., the relative strength of the debt-like or equity-like terms and features given the facts and circumstances) when considering how to weight those terms and features. The amendments in this ASU are effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption, including adoption in an interim period, is permitted. The Company does not expect the adoption of ASU 2014-16 to have a material impact on its consolidated financial statements.
	In November 2014, the FASB issued ASU No. 2014-17, “Business Combinations (Topic 805): Pushdown Accounting.” The amendments in ASU provide an acquired entity with an option to apply pushdown accounting in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity. An acquired entity may elect the option to apply pushdown accounting in the reporting period in which the change-in-control event occurs. An acquired entity should determine whether to elect to apply pushdown accounting for each individual change-in-control event in which an acquirer obtains control of the acquired entity. If pushdown accounting is not applied in the reporting period in which the change-in-control event occurs, an acquired entity will have the option to elect to apply pushdown accounting in a subsequent reporting period to the acquired entity’s most recent change-in-control event. An election to apply pushdown accounting in a reporting period after the reporting period in which the change-in-control event occurred should be considered a change in accounting principle in accordance with Topic 250, Accounting Changes and Error Corrections. If pushdown accounting is applied to an individual change-in-control event, that election is irrevocable. The amendments in this ASU are effective on November 18, 2014. After the effective date, an acquired entity can make an election to apply the guidance to future change-in-control events or to its most recent change-in-control event. However, if the financial statements for the period in which the most recent change-in-control event occurred already have been issued or made available to be issued, the application of this guidance would be a change in accounting principle. The Company does not expect the adoption of ASU 2014-17 to have a material impact on its consolidated financial statements.
	In January 2015, the FASB issued ASU No. 2015-01, “Income Statement-Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items.” The amendments in this ASU eliminate from U.S. GAAP the concept of extraordinary items. Subtopic 225-20, Income Statement - Extraordinary and Unusual Items, required that an entity separately classify, present, and disclose extraordinary events and transactions. Presently, an event or transaction is presumed to be an ordinary and usual activity of the reporting entity unless evidence clearly supports its classification as an extraordinary item. If an event or transaction meets the criteria for extraordinary classification, an entity is required to segregate the extraordinary item from the results of ordinary operations and show the item separately in the income statement, net of tax, after income from continuing operations. The entity also is required to disclose applicable income taxes and either present or disclose earnings-per-share data applicable to the extraordinary item. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The Company does not expect the adoption of ASU 2015-01 to have a material impact on its consolidated financial statements.
