Accordingly, the Company and BNC are examined periodically by those regulatory authorities.
	These consolidated financial statements and notes are presented in accordance with the instructions for Form 10-Q and, therefore, do not include all information and notes necessary for a complete presentation of financial position, results of operations and cash flow activity required in accordance with accounting principles generally accepted in the United States of America (“GAAP”). In the opinion of management, all normal recurring adjustments necessary for a fair statement of the consolidated financial position and consolidated results of operations have been made. The information contained in the consolidated financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013 should be referred to in connection with these unaudited interim consolidated financial statements.
	Certain amounts in the 2013 consolidated financial statements have been reclassified to conform to 2014 presentation. These reclassifications had no effect on net income, net income available to common shareholders or shareholders' equity as previously reported.
	The preparation of consolidated financial statements in conformity with GAAP 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 financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. On an ongoing basis, the Company evaluates its estimates, including those relating to the allowance for loan losses, determination of fair value of acquired assets and assumed liabilities, and valuation of goodwill and intangible assets.
	Recently Adopted and Issued Accounting Standards
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606). This ASU was developed as a joint project with the International Accounting Standards Board to remove inconsistencies in revenue requirements and provide a more robust framework for addressing revenue issues. The ASU’s core principle is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services. The ASU is effective for public entities for annual and interim periods beginning after December 15, 2016. The ASU may be adopted using either a modified retrospective method or a full retrospective method and early adoption is not permitted. The Company is currently evaluating the impact of the adoption of this ASU on its consolidated financial statements.
	In January 2014, the FASB issued ASU No. 2014-04, Receivables (Topic 310): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure, to clarify that an in substance repossession or foreclosure occurs upon either the creditor obtaining legal title to the residential real estate property or 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. The amendments are effective for annual periods, and interim reporting periods within those annual periods, beginning after December 15, 2014. The amendments may be adopted using either a modified retrospective transition method or a prospective transition method and early adoption is permitted. The Company does not expect the adoption of this ASU to have a material impact on its consolidated financial statements.
	In July 2013, the FASB issued ASU No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, to provide guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists thereby reducing diversity in practice. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted. The amendments are to be applied prospectively to all unrecognized tax benefits that exist at the effective date with retrospective application permitted. The adoption of this ASU did not have a material impact on the Company's consolidated financial statements.

The Company has determined the above noted acquisitions each constitute a business combination as defined by FASB ASC Topic 805: Business Combinations (“ASC Topic 805”), which establishes principles and requirements for how the acquirer of a business recognizes and measures in its financial statements the identifiable assets acquired and the liabilities assumed. The Company has recorded the assets purchased and liabilities assumed at their estimated fair value in accordance with ASC Topic 805.
The estimated fair values are subject to refinement for up to one year after the closing date of the acquisition as additional information regarding closing date fair value becomes available. During this one year period, the causes of any changes in cash flow estimates are considered to determine whether the change results from circumstances that existed at the acquisition date or if the change results from an event that occurred after the date of acquisition.

Earnings Per Share	'
	EARNINGS PER SHARE
	Basic earnings per common share is computed using the weighted average number of common shares and participating securities outstanding during the reporting period. Diluted earnings per common share is the amount of earnings available to each share of common stock during the reporting period adjusted to include the effect of potentially dilutive common shares. Potentially dilutive common shares include incremental shares issued for stock options and restricted stock awards (collectively referred to herein as “Stock Rights”). Potentially dilutive common shares are excluded from the computation of dilutive earnings per share in the periods in which the effect would be anti-dilutive.
	The Company's basic and diluted earnings per share calculations are presented in the following table (dollars in thousands, except per share data):

	During the nine months ended September 30, 2014, the Company made two sales of securities that were classified as held-to-maturity. The Company sold $3.3 million of state and municipal debt obligations that were downgraded by Moody's as a result of allegations of fraud and multiple pending investigations of the issuer. As a result of the downgrade of the securities, the Company's intent to hold these securities changed and management elected to divest of its interest in the downgraded securities. The Company recorded a realized gain of $0.2 million on this sale.
	The Company also sold $5.2 million of corporate debt securities due to regulatory capital restrictions. The Company recorded a realized loss of $0.1 million on this sale.
	As the Company's intent and ability to hold the remaining held-to-maturity securities was not impacted by these sales, the Company did not reclassify the remaining securities to the available-for-sale category.

All state and municipal securities in an unrealized loss position were rated as investment grade at September 30, 2014. The Company noted that, of the 89 municipal securities in an unrealized loss position for greater than 12 months, only two had an unrealized loss of greater than 5% of their carrying value, and none of the unrealized losses were greater than 12% of the carrying value. The corporate debt securities are issued by well-capitalized and sound financial institutions. The other debt security is backed by a pool of student loan debt and has an investment grade rating. The gross unrealized losses reported for the mortgage-backed securities relate to investment securities issued by the Federal National Mortgage Association, the Government National Mortgage Association, or Federal Home Loan Mortgage Corporation. The Company does not intend to sell, and it is not more likely than not that the Company will be required to sell, these investment securities before the anticipated recovery of the amortized cost basis. The unrealized losses for the debt securities are caused by changes in market interest rates and not credit concerns related to the respective issuers.
The equity securities held by the Company in an unrealized loss position at September 30, 2014 consist of publicly-traded common stock of an investment company and there are no concerns about the long-term viability of the issuer. The Company has the positive intent and ability to hold these securities until the anticipated recovery of value occurs.
Based on this analysis, the Company does not consider any investment securities to be other-than-temporarily impaired at September 30, 2014.

	-1	Amount includes $149.0 million and $187.7 million of acquired loans covered under FDIC loss-share agreements at September 30, 2014 and December 31, 2013, respectively. The unpaid principal balance for acquired loans covered under FDIC loss-share agreements was $152.6 million and $195.4 million at September 30, 2014 and December 31, 2013, respectively.
	Covered loans acquired will be reimbursed for a substantial portion of any future losses on them under the terms of the FDIC loss-share agreements. The covered loans are reported in loans exclusive of the expected reimbursement from the FDIC. Covered loans are initially recorded at fair value at the acquisition date. The covered loans are and will be subject to the Company’s internal and external credit review and monitoring. Prospective losses incurred on covered loans are eligible for partial reimbursement by the FDIC. Subsequent decreases in the amount expected to be collected result in a provision for loan losses, an increase in the allowance for loan losses, and a proportional increase to the FDIC indemnification asset for the estimated amount to be reimbursed. Subsequent increases in the amount expected to be collected result in the reversal of any previously-recorded provision for loan losses and related allowance for loan losses and decreases to the FDIC indemnification asset, or accretion of certain fair value amounts into interest income in future periods if no provision for loan losses had been recorded.
	A portion of the fair value discount on acquired covered loans has an accretable yield associated with those loans that is accreted into interest income over the estimated remaining life of the loans. The remaining non-accretable difference represents cash flows not expected to be collected. The following table details changes in the carrying amount of covered acquired loans and accretable yield for loans receivable for the nine months ended September 30, 2014 and year ended December 31, 2013 (dollars in thousands):
		2014								2013

	Balance at end of period	$	(2,916	)		$	148,957			$	(6,058	)		$	187,661
	The Company evaluates loans acquired with evidence of credit deterioration in accordance with the provisions of ASC Topic 310-30: Loans and Debt Securities Acquired with Deteriorated Credit Quality ("ASC 310-30"). Credit-impaired loans are those loans showing evidence of credit deterioration since origination and it is probable, at the date of acquisition, the Company will not collect all contractually required principal and interest payments. Generally, the acquired loans that meet the Company’s definition for nonaccrual status fall within the definition of credit-impaired covered loans. The following table presents loans acquired during the nine months ended September 30, 2014, at acquisition date, accounted for under ASC Topic 310-30 (dollars in thousands):
	Contractually required payments receivable	$	40,012
	Contractual cash flows not expected to be collected (non-accretable)	(7,885		)
	Expected cash flows	32,127
	Interest component of expected cash flows	(3,397		)
	Fair value of loans acquired	$	28,730
	The acquisition date unpaid balance of loans acquired during the nine months ended September 30, 2014 that did not have credit deterioration was $307.1 million, with an estimated fair value of $287.0 million. The discount of $20.1 million will be amortized on a level-yield basis over the economic life of the loans.
	The Company has the ability to borrow funds from the Federal Home Loan Bank (“FHLB”) and from the Federal Reserve Bank. At September 30, 2014 and December 31, 2013, real estate loans with carrying values of $947.4 million and $759.2 million, respectively, were pledged to secure borrowing facilities from these institutions.
	The Company has adopted comprehensive lending policies, underwriting standards and loan review procedures, which are reviewed on a regular basis.   Each class of financing receivable detailed below is subject to risks that could have an adverse impact on the credit quality of the loan portfolio.
	Commercial real estate loans
	Commercial real estate loans consist primarily of loans secured by nonresidential (owner-occupied and/or non-owner occupied) real estate, multifamily housing, retail strip centers and hotels. Commercial real estate is primarily dependent on successful operation or management of the property in order to generate sufficient cash to repay the outstanding debt. While these loans are normally secured by commercial buildings for office, storage and warehouse space, it is possible that the liquidation of the collateral will not fully satisfy the obligation. High unemployment, generally weak economic conditions or oversupply of properties may result in customers having to provide rental rate concessions to achieve adequate occupancy rates.
	Commercial construction loans
	Commercial construction loans, including land development loans, are highly dependent on the supply and demand for commercial real estate in the markets served by BNC as well as the demand for newly constructed residential homes and lots that customers are developing. Continuing deterioration in demand could result in significant decreases in the underlying collateral values and make repayment of the outstanding loans more difficult for customers.
	Commercial and industrial loans and leases
	Each commercial loan or lease is underwritten based primarily upon the customer’s ability to generate the required cash flow to service the debt in accordance with the contractual terms and conditions of the loan agreement. A complete understanding of the borrower’s businesses including the experience and background of the principals is obtained prior to approval. Collateral securing these loans is primarily business assets such as inventory or accounts receivable. To the extent that the principals or other parties provide personal guarantees, the relative financial strength and liquidity of each guarantor is assessed. Common risks include general economic conditions within the markets BNC serves, as well as risks that are specific to each transaction, including demand for products and services and reductions in the fair value of collateral.
	Residential construction loans
	Residential construction loans are made to established homebuilders and are typically secured by 1-4 family residential property.
	Residential mortgage loans
	Each residential mortgage loan is underwritten using credit scoring and analysis tools. These credit scoring tools take into account factors such as payment history, credit utilization, length of credit history, types of credit currently in use, and recent credit inquiries. The borrowers' debt-to-income ratio, sources of income and employment history, among other factors, are also evaluated as part of the underwriting process. To the extent that the loan is secured by collateral, the likely value of that collateral is evaluated. Common risks to each class of non-commercial loans include risks that are not specific to individual transactions such as general economic conditions within the markets BNC serves, particularly unemployment and potential declines in real estate values. Personal events such as disability or change in marital status also add risk to residential mortgage loans. Second mortgage loans and home equity lines of credit generally involve greater credit risk than first mortgage loans because they are secured by mortgages that are subordinate to the first mortgage on the property.  If the borrower is forced into foreclosure, the Company will not receive any proceeds from the sale of the property until the first mortgage has been satisfied.
	At September 30, 2014, second mortgage loans and home equity lines of credit for which the Company did not own or service the related first mortgage loans totaled approximately $176.6 million, which represented approximately 98% of the total second liens held by the Company.  Since substantially all first mortgage loans originated by the Company are eligible for sale in the secondary market, and the Company typically does not service the related first mortgage loans if they are sold, the Company may be unable to track the delinquency status of the related first mortgage loans and whether such loans are at risk of foreclosure by others.  The Company monitors the increased credit risk associated with second mortgage loans and home equity lines of credit for which the Company does not own or service the related first mortgage loans as part of the overall management of the relationship. If the Company identifies significant deterioration in a borrower’s credit quality, the Company may freeze the borrower’s ability to make additional principal draws under the home equity lines of credit.
	Home equity lines of credit are offered as “revolving” lines of credit which have a 15 year maturity and draw period. Borrowers are able to choose scheduled monthly interest-only payments during the term of the line or monthly payments of 1.5% of the outstanding prinicpal, along with associated interest. The full principal amount is due at maturity as a lump-sum balloon payment under the interest-only payment option.  At September 30, 2014, approximately 98% of the home equity lines of credit were paying scheduled monthly interest-only payments. At maturity, home equity loans are re-underwritten based on our current underwriting standards and updated appraisals are obtained.  Our underwriting criteria includes analysis of the loan amount in relation to the borrower's total mortgage debt, in addition to normal credit underwriting guidelines.  If the borrower qualifies under our current underwriting standards, the loans are either renewed, converted to conventional second mortgage loans that are fully amortizing, or refinanced along with the existing first mortgage into a new first mortgage loan.  Borrowers may be required to repay a portion of the outstanding principal balance to qualify for such renewals.
	The following table summarizes the maturity dates of our home equity lines of credit at September 30, 2014 (dollars in thousands):
	2014	$	1,871
	2015	3,184
	2016	4,958
	2017	6,027
	2018	7,248
	Thereafter	256,618
		$	279,906
	Consumer and other loans
	Consumer and other loans include loans secured by personal property such as residential real estate, automobiles, marketable securities, other titled recreational vehicles including boats and motorcycles, as well as unsecured consumer debt. The value of underlying collateral within this class is especially volatile due to potential rapid depreciation in values since date of loan origination in excess of principal repayment. Consumer loan collections are sensitive to job loss, illness and other personal factors.

-1	The provision for loan losses includes the "net" provision on covered loans after coverage provided by FDIC loss-share agreements, which totaled $(0.1) million and $(0.3) million for the three and nine months ended September 30, 2014, respectively. This resulted in a decrease in the FDIC indemnification asset of $(0.4) million and $(1.2) million, which is the difference between the net provision on covered loans and the total additions to the allowance for loan losses allocable to the covered loan portfolio of $(0.5) million and $(1.5) million for the three and nine months ended September 30, 2014, respectively.
-2	The provision for loan losses includes the "net" provision on covered loans after coverage provided by FDIC loss-share agreements, which totaled $0.2 million and $0.6 million for the three and nine months ended September 30, 2013, respectively. This resulted in an increase in the FDIC indemnification asset of $0.9 million and $2.6 million, which is the difference between the net provision on covered loans and the total additions to the allowance for loan losses allocable to the covered loan portfolio of $1.2 million and $3.2 million for the three and nine months ended September 30, 2013.

For the three and nine months ended September 30, 2014 and 2013, the amount of interest income recognized within the period that the loans were impaired was primarily related to loans modified in a troubled debt restructuring (“TDR”) that remained on accrual status. For the three and nine months ended September 30, 2014 and 2013, the amount of interest income recognized using a cash-basis method of accounting during the period that the loans were impaired was not material.

Credit quality indicators
The Company uses several credit quality indicators to manage credit risk in an ongoing manner. The Company's primary credit quality indicators use an internal credit risk rating system that categorizes loans and leases into pass, special mention, or classified categories. Credit risk ratings are applied individually to those classes of loans and leases that have significant or unique credit characteristics that benefit from a case-by-case evaluation. These are typically loans and leases to businesses or individuals in the classes which comprise the commercial portfolio segment. Groups of loans and leases that are underwritten and structured using standardized criteria and characteristics are typically risk rated and monitored collectively. These are typically loans and leases to individuals in the classes which comprise the consumer portfolio segment.
At least annually the Company will review all loans exceeding a certain threshold and assign a risk rating. Loans excluded from the scope of the annual review process are generally classified as pass credits until: (a) they become past due; (b) management becomes aware of a deterioration in the creditworthiness of the borrower; or (c) the customer contacts the Company for a modification or new loan. The Company uses the following definitions for risk ratings:
Special Mention. Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date.
Substandard. Loans classified as substandard are inadequately protected by the current net worth and payment capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.
Doubtful. Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.
Loss. Loans classified as loss are considered uncollectible and are in the process of being charged-off, as soon as practical, once so classified.

Modifications
A modification of a loan constitutes a TDR when a borrower is experiencing financial difficulty and the modification constitutes a concession.  The Company offers various types of concessions when modifying a loan; however, forgiveness of principal is rarely granted.  Commercial and industrial loans modified in a TDR often involve temporary interest-only payments, term extensions, and converting revolving credit lines to term loans.  Additional collateral, a co-borrower, or a guarantor is often requested.  Commercial mortgage and construction loans modified in a TDR often involve reducing the interest rate for the remaining term of the loan, extending the maturity date at an interest rate lower than the current market rate for new debt with similar risk, or substituting or adding a new borrower or guarantor.  Construction loans modified in a TDR may also involve extending the interest-only payment period.  Residential mortgage loans modified in a TDR are primarily comprised of loans where monthly payments are lowered to accommodate the borrowers’ financial needs for a period of time.  After the lowered monthly payment period ends, the borrower reverts back to paying principal and interest per the original terms with the maturity date adjusted accordingly.  Land loans are also included in the class of residential mortgage loans.  Land loans are typically structured as interest-only monthly payments with a balloon payment due at maturity.  Land loans modified in a TDR typically involve extending the balloon payment by one to three years, or changing the monthly payments from interest-only to principal and interest.  Home equity modifications are made infrequently and are not offered if the Company also holds the first mortgage.  Home equity modifications are uniquely designed to meet the specific needs of each borrower.  Occasionally, the terms will be modified to a standalone second lien mortgage, thereby changing their loan class from home equity to residential mortgage.
Loans modified in a TDR are, in many cases, already on nonaccrual status and partial charge-offs have in some cases already been taken against the outstanding loan balance.  As a result, loans modified in a TDR for the Company may have the financial effect of increasing the specific allowance associated with the loan.  An allowance for impaired consumer and commercial loans that have been modified in a TDR is measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s observable market price, or the estimated fair value of the collateral, less any selling costs, if the loan is collateral dependent.  Management exercises significant judgment in developing these estimates. Once we classify a loan a TDR, the loan is only removed from TDR classification under three circumstances: (1) the loan is paid off, (2) the loan is charged off or (3) if, at the beginning of the current fiscal year, the loan has performed in accordance with the modified terms for a minimum of six consecutive months and at the time of modification the loan’s interest rate represented a then current market interest rate for a loan of similar risk.

At September 30, 2014 and December 31, 2013, the Company had no available commitments outstanding on TDRs.
The Company offers a variety of modifications to borrowers. The modification categories offered can generally be described in the following categories:
Rate modification - A modification in which the interest rate is changed.
Term modification - A modification in which the maturity date, timing of payments or frequency of payments is changed.
Interest only modification – A modification in which the loan is converted to interest only payments for a period of time.
Payment modification – A modification in which the principal and interest payment are lowered from the original contractual terms.
Combination modification – Any other type of modification, including the use of multiple categories above.
The following tables present new TDRs by modification category (dollars in thousands). All balances represent the recorded investment at the end of the period in which the modification was made.

FDIC Indemnification Asset [Abstract]	'
FDIC Indemnification Asset	'
	FDIC INDEMNIFICATION ASSET
	The Company has recorded an indemnification asset related to loss-share agreements entered into with the FDIC wherein the FDIC will reimburse the Company for certain amounts related to certain acquired loans and other real estate owned should the Company experience a loss. Under the loss-sharing arrangements, the FDIC has agreed to absorb 80% of all future losses and workout expenses on these assets which occur prior to the expiration of the loss-sharing agreements. The Company entered into the respective loss-share agreements with the acquisitions of Beach First National Bank (“Beach First”) and Blue Ridge Savings Bank (“Blue Ridge”).
	Each loss-sharing arrangement consists of one single family residential mortgage loan agreement and one commercial and other loans and other real estate owned agreement. The commercial and other loan and other real estate owned loss-share agreements provide for FDIC loss-sharing for five years from April 9, 2010 and October 14, 2011 for the purchases of Beach First and Blue Ridge, respectively, and reimbursement to the FDIC for eight years from these dates. The single family residential mortgage loan loss-share agreements provide for FDIC loss-sharing and reimbursement for recoveries to the FDIC for ten years from these dates for the purchases, and reimbursement to the FDIC for ten years from these dates.
	The following table presents activity for the FDIC indemnification asset (dollars in thousands):

Derivative Instruments and Hedging Activities Disclosure [Abstract]	'
Derivatives	'
	DERIVATIVES
	The Company utilizes derivative financial instruments primarily to hedge its exposure to changes in interest rates. All derivative financial instruments are recorded on the balance sheet at their respective fair values. The Company does not use financial instruments or derivatives for any trading or other speculative purposes.
	The primary focus of the Company’s asset/liability management program is to monitor the sensitivity of the Company’s net portfolio value and net income under varying interest rate scenarios to take steps to control its risks. On a quarterly basis, the Company simulates the net portfolio value and net income expected to be earned over a twelve-month period following the date of simulation. The simulation is based on a projection of market interest rates at varying levels and estimates the impact of such market rates on the levels of interest-earning assets and interest-bearing liabilities during the measurement period. Based upon the outcome of the simulation analysis, the Company considers the use of derivatives as a means of reducing the volatility of net portfolio value and projected net income within certain ranges of projected changes in interest rates. The Company evaluates the effectiveness of entering into any derivative instrument agreement by measuring the cost of such an agreement in relation to the reduction in net portfolio value and net income volatility within an assumed range of interest rates. The Company also has derivatives that are a result of a service it provides to certain qualifying customers, which includes a matched book of derivative instruments offered to customers in order to minimize their interest rate risk.
	Derivatives Designated as Cash Flow Hedges of Interest Rate Risk
	The Company has variable rate funding which creates exposure to variability in interest payments due to changes in interest rates. In March 2013, the Company entered into a forward-starting interest rate swap transaction with a notional amount of $125 million to effectively convert $125 million of its variable-rate money market funding arrangement to fixed interest rate debt at the forward-starting date of the swap transaction. The effective date of this interest rate swap was September 16, 2014 and the termination date is March 18, 2019. The swap transaction was designated as a cash flow hedge of the changes in cash flows attributable to changes in one-month LIBOR, the benchmark interest rate being hedged, associated with the interest payments made on the first $125 million of the Company's variable rate money market funding arrangement, which are indexed to one-month LIBOR.
	During the first quarter of 2009, the Company entered into a five year interest rate derivative contract, with a notional amount of $250 million, to offset the effects of interest rate changes on an unsecured $250 million variable rate money market funding arrangement. The interest rate cap matured on February 16, 2014.
	Derivatives Not Designated as Hedges
	The Company utilizes derivative financial instruments, including interest rate swaps, caps and/or floors, as part of its ongoing efforts to mitigate its interest rate risk exposure and to help its commercial customers manage their exposure to interest rate fluctuations. To mitigate the interest rate risk associated with these customer contracts, the Company enters into an offsetting derivative contract position. These derivative positions are recorded at fair value on the Company’s consolidated balance sheet and, due to the matched nature of these derivative instruments, changes in fair value do not impact the Company’s earnings. At September 30, 2014 and December 31, 2013, the Company had notional amounts of $34.9 million and $31.2 million, respectively, on interest rate contracts with corporate customers and in offsetting interest rate contracts with another financial institution to mitigate the Company’s rate exposure on its corporate customers’ contracts.
	The following table presents the fair value of the Company’s derivatives (dollars in thousands):

	The derivative instruments held by the Company are subject to master netting arrangements which contain a legally enforceable right to offset recognized amounts and settle such amounts on a net basis. The Company has elected to present the financial assets and financial liabilities associated with these arrangements on a gross basis in the Consolidated Balance Sheets. Cash collateral is posted by the counterparty with net liability positions in accordance with contract thresholds.
	Information about financial instruments that are eligible for offset in the consolidated balance sheets is presented in the following table (dollar amounts in thousands):

	The Company has recorded a net gain of $0.4 million, net of tax, as accumulated other comprehensive income at September 30, 2014 associated with cash flow hedging instruments and expects $1.5 million, net of tax, to be reclassified as an increase to interest expense during the next 12 months. The following table presents the amounts recorded in the Consolidated Statements of Income and Consolidated Statements of Comprehensive Income, respectively, relating to derivative instruments designated as cash flow hedges (dollars in thousands, net of tax):
		Three months ended September 30,						Nine months ended September 30,
		2014		2013				2014				2013
	Derivatives designated as hedging instruments:
	Amount of net gains (losses) recorded in OCI (effective portion)	$	305	$	(599	)		$	(1,315	)		$	1,205
	Amount of net losses reclassified from OCI to earnings (1)	—		1,613				286				4,402
	(1) Amount recorded in interest expense on demand deposits in the Consolidated Statements of Income.
	The amounts included in accumulated other comprehensive income will be reclassified to interest expense should the hedges no longer be considered effective. No amount of ineffectiveness was included in net income for the three and nine months ended September 30, 2014 and 2013. The Company will continue to assess the effectiveness of the hedges on a quarterly basis.
	Counterparty Credit Risk - By entering into derivative instrument contracts, the Company exposes itself, from time to time, to counterparty credit risk. Counterparty credit risk is the failure of the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is in an asset position, the counterparty has a liability to the Company, which creates credit risk for the Company. The Company attempts to minimize this risk by selecting counterparties with investment grade credit ratings, limiting its exposure to any single counterparty and regularly monitoring its market position with each counterparty.
	Credit-Risk Related Contingent Features – The Company’s derivative instruments contain provisions allowing the financial institution counterparty to terminate the contracts in certain circumstances, such as a default by the Company on its indebtedness or the failure to maintain its regulatory status as a well-capitalized institution. These derivative agreements also contain provisions regarding the posting of collateral by each party. At September 30, 2014, the aggregate fair value of derivative instruments with credit-risk-related contingent features that were in a net liability position was $0.5 million, for which the Company has posted collateral with a fair value of $2.3 million.

	On September 30, 2014, the Company issued $60.0 million of 5.5% Fixed to Floating Rate Subordinated Notes (the "Subordinated Notes"). The Subordinated Notes bear interest at a fixed rate of 5.5% per year for the first five years and, from October 1, 2019 to the October 1, 2024 maturity date, the interest rate will reset quarterly to an annual interest rate equal to the then current three-month LIBOR plus 359 basis points. The Subordinated Notes are redeemable by the Company at any quarterly interest payment date beginning on October 1, 2019 to maturity at par, plus accrued and unpaid interest. A portion of the proceeds from the sale of Subordinated Notes were used to repay the outstanding principal balance, along with accrued interest and prepayment penalties, on the term loan, while the remainder will be used for general corporate purposes.
	The Company may purchase federal funds through unsecured federal funds lines of credit totaling $65.0 million at September 30, 2014.

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	FAIR VALUE MEASUREMENT
	ASC Topic 820, Fair Value Measurements and Disclosures, establishes a framework for measuring fair value, establishes a three-level valuation hierarchy for disclosure of fair value measurement and enhances disclosure requirements for fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability at the measurement date. The three levels of valuations are defined as follows:
	Level 1 – Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.
	Level 2 – Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.
	Level 3 – Inputs to the valuation methodology are unobservable and significant to the fair value measurement, and require significant management judgment or estimation using pricing models, discounted cash flow methodologies or similar techniques.
	Fair Value on a Recurring Basis – The Company measures certain assets at fair value on a recurring basis and the following is a general description of the methods used to value such assets.
	Investment securities available-for-sale – The fair value of a portion of our investment in equity securities available-for-sale is determined by observing quoted prices in an active market for identical securities. As such, the Company classifies these securities as Level 1 valuation. The fair value of the remainder of our investment securities available-for-sale are determined by a third-party pricing service. The valuations provided by the third-party pricing service are based on observable market inputs, which include benchmark yields, reported trades, issuer spreads, benchmark securities, bids, offers and reference data obtained from market research publications. The valuation of mortgage-backed securities also includes new issue data, monthly payment information and “To Be Announced” prices. The valuation of state and municipal securities also include the use of material event notices. We review the prices supplied by the independent pricing service, as well as their underlying pricing methodologies, for reasonableness. At least annually, we will validate prices supplied by the independent pricing service by comparing to prices obtained from a second third-party source. The Company classifies these investment securities as Level 2 valuation.
	Derivative assets and liabilities – The values of derivative instruments held or issued by the Company for risk management purposes are traded in over-the-counter markets where quoted market prices are not readily available. For those derivatives, the Company measures fair value using models that use primarily market observable inputs, such as yield curves and option volatilities, and include the value associated with counterparty credit risk. The Company classifies derivative instruments as Level 2 valuation.

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

Estimated fair values of financial instruments have been estimated by the Company using the provisions of ASC Topic 825, Financial Instruments (“ASC 825”), which requires disclosure of fair value information about financial instruments, whether or not recognized in the balance sheet, for which it is practicable to estimate that value. 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. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instruments. ASC 825 excludes certain financial instruments and all nonfinancial instruments from its disclosure requirements. Accordingly, the aggregate fair value amounts presented do not represent the underlying value of the Company.
The following tables present the carrying value and estimated fair values of the Company’s financial instruments, including those that are not measured and reported at fair value on a recurring basis or nonrecurring basis (dollars in thousands):

The following methods and assumptions were used to estimate the fair value of financial instruments that have not been previously discussed:
Cash and cash equivalents - The carrying amounts reported in the balance sheets for cash and cash equivalents approximate the fair value of those assets.
Investment securities held-to-maturity - The fair value of our investment securities held-to-maturity are determined by a third-party pricing service. The valuations provided by the third-party pricing service for state and municipal securities are based on observable market inputs, which include benchmark yields, reported trades, issuer spreads, benchmark securities, bids, offers and the use of material event notices.
We review the prices supplied by the independent pricing service, as well as their underlying pricing methodologies, for reasonableness. At least annually, we will validate prices supplied by the independent pricing service by comparing to prices obtained from a second third-party source.
Federal Home Loan Bank stock - The fair value for FHLB stock is its carrying value, since this is the amount for which it could be redeemed. There is no active market for this stock and the Company, in order to be a member of the FHLB, is required to maintain a minimum investment.
Loans receivable, net - The fair values for loans are estimated using discounted cash flow analyses using interest rates currently being offered for loans with similar terms and credit ratings for the same remaining maturities, adjusted for the allowance for loan losses.
FDIC indemnification asset - The fair value for the FDIC indemnification asset is estimated based on discounted future cash flows using current discount rates.
Investment in bank-owned life insurance - The carrying value of life insurance approximates fair value because this investment is carried at cash surrender value, as determined by the insurer.
Accrued interest receivable and accrued interest payable - The carrying amount of accrued interest is assumed to approximate fair value.
Deposits - The fair values disclosed for deposits with no stated maturity (e.g., interest and non-interest checking, passbook savings, and certain types of money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). Fair values for deposits with a stated maturity date (time deposits) are estimated using a discounted cash flow calculation that applies interest rates currently being offered on these accounts to a schedule of aggregated expected monthly maturities on time deposits.
Short-term borrowings - The carrying amount of short-term borrowings is assumed to approximate fair value.
Long-term debt – The fair value is estimated by discounting the future contractual cash flows using current market interest rates for similar debt over the same remaining term.

Commitment and Contingencies	'
	COMMITMENTS AND CONTINGENCIES
	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. These financial instruments include commitments to extend credit, unfunded lines of credit, and standby letters of credit. These instruments involve elements of credit risk in excess of amounts recognized in the accompanying consolidated financial statements.
	The Company's risk of loss in the event of nonperformance by the other party to the commitment to extend credit, lines of credit and standby letters of credit is represented by the contractual amount of these instruments. The Company uses the same credit policies in making commitments under such instruments as it does for on-balance sheet instruments. The amount of collateral obtained, if any, is based on management's evaluation of the borrower. Collateral held varies, but may include accounts receivable, inventory, real estate and time deposits with financial institutions. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent cash requirements.
	The Company committed to invest up to $8.8 million in limited partnership interests of unconsolidated entities, of which $5.9 million was unfunded at September 30, 2014.
	The following tables present the outstanding off-balance sheet financial instruments whose contract amounts represent potential credit risk (dollars in thousands):
		30-Sep-14		31-Dec-13
	Commitments under unfunded loans and lines of credit	$	586,800	$	377,021
	Letters of credit	5,140		7,926
	Unused credit card lines	4,555		4,120
	Unfunded commitments for unconsolidated investments	5,850		7,450
	The Company is subject in the normal course of business to various pending and threatened legal proceedings in which claims for monetary damages are asserted. Management, after consultation with legal counsel, does not anticipate that the aggregate ultimate liability arising out of litigation pending or threatened against the Company will be material to the Company’s consolidated financial position. On an on-going basis the Company assesses any potential liabilities or contingencies in connection with such legal proceedings. For those matters where it is deemed probable that the Company will incur losses and the amount of the losses can be reasonably estimated, the Company would record an expense and corresponding liability in its consolidated financial statements.

	EMPLOYEE BENEFITS
	The Compensation Committee of the Company's Board of Directors may grant or award eligible participants stock options, restricted stock, restricted stock units, stock appreciation rights, and other stock-based awards or any combination of awards (collectively referred to herein as “Rights”). At September 30, 2014, the Company had Rights outstanding from the 2006 BNC Bancorp Omnibus Stock Ownership and Long Term Incentive Plan (the "2006 Omnibus Plan"), the BNC Bancorp 2013 Omnibus Stock Incentive Plan (the "2013 Omnibus Plan") and the KeySource Non-Statutory and Incentive Stock Option plans (the "KeySource Plans"). At September 30, 2014, the 2013 Omnibus Plan and the KeySource Plans are the only plans that are available for future grants. At September 30, 2014, the Company had 253,842 Rights issued under the 2006 Omnibus Plan, 122,323 Rights issued and 1,330,722 Rights available for grants or awards under the 2013 Omnibus Plan, and 242,586 stock options issued and 35,607 stock options available for issuance related to the KeySource Plans.
	Stock Option Awards. The fair value of each option award is estimated on the date of grant using the Black-Scholes-Merton option pricing model. The risk-free interest rate is based on the U.S. Treasury rate for the expected life at the time of grant. Volatility is based on the average volatility of the Company based upon previous trading history. The expected life and forfeiture assumptions are based on historical data. Dividend yield is based on the yield at the time of the option grant. There were no grants of options during the nine months ended September 30, 2014.
	A summary of the Company’s stock option activity for the nine months ended September 30, 2014 is presented below (dollars in thousands, except per share data):
		Shares		Weighted Average Exercise Price per Share		Weighted Average Remaining Contractual Term (Years)	Aggregate Intrinsic Value
	Outstanding at December 31, 2013	412,337		$	11.34
	Exercised	62,258		11.27
	Forfeited or expired	—		—
	Outstanding at September 30, 2014	350,079		$	11.35	2.5	$	1,508
	Exercisable at September 30, 2014	348,655		$	11.36	2.49	$	1,500
	Share options expected to vest	1,424		$	9.67	5.52	$	8
	The related compensation expense recognized for stock options was immaterial for the nine months ended September 30, 2014 and 2013, respectively. At September 30, 2014, there was an immaterial amount of total unrecognized compensation cost related to non-vested stock options granted under the plans. That cost is expected to be recognized over a weighted average period of 0.61 years.
	Restricted Stock Awards. A summary of the activity of the Company’s unvested restricted stock awards for the nine months ended September 30, 2014 is presented below:
		Number of Shares		Weighted Average Grant-Date Fair Value
	Unvested at December 31, 2013	303,396		$	9.58
	Granted	100,603		17.18
	Vested	(133,327	)	9.96
	Forfeited	(2,000	)	15.23
	Unvested at September 30, 2014	268,672		$	12.2
	The Company measures the fair value of restricted shares based on the price of the Company's common stock on the grant date, and compensation expense is recorded over the vesting period. The related compensation expense recognized for restricted stock awards for the nine months ended September 30, 2014 and 2013 was $1.2 million and $0.8 million, respectively. At September 30, 2014, there was $2.7 million of total unrecognized compensation cost related to unvested restricted stock granted under the plans. That cost is expected to be recognized over a weighted average period of 1.49 years. The grant-date fair value of restricted stock grants vested during the nine months ended September 30, 2014 was $1.3 million.

Accounting Policies [Abstract]	'
Basis of Presentation	'
	These consolidated financial statements and notes are presented in accordance with the instructions for Form 10-Q and, therefore, do not include all information and notes necessary for a complete presentation of financial position, results of operations and cash flow activity required in accordance with accounting principles generally accepted in the United States of America (“GAAP”). In the opinion of management, all normal recurring adjustments necessary for a fair statement of the consolidated financial position and consolidated results of operations have been made. The information contained in the consolidated financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013 should be referred to in connection with these unaudited interim consolidated financial statements.
Reclassifications	'
	Certain amounts in the 2013 consolidated financial statements have been reclassified to conform to 2014 presentation. These reclassifications had no effect on net income, net income available to common shareholders or shareholders' equity as previously reported.
Use of Estimates	'
	The preparation of consolidated financial statements in conformity with GAAP 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 financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. On an ongoing basis, the Company evaluates its estimates, including those relating to the allowance for loan losses, determination of fair value of acquired assets and assumed liabilities, and valuation of goodwill and intangible assets.
Recently Adopted and Issued Accounting Standards	'
	Recently Adopted and Issued Accounting Standards
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606). This ASU was developed as a joint project with the International Accounting Standards Board to remove inconsistencies in revenue requirements and provide a more robust framework for addressing revenue issues. The ASU’s core principle is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services. The ASU is effective for public entities for annual and interim periods beginning after December 15, 2016. The ASU may be adopted using either a modified retrospective method or a full retrospective method and early adoption is not permitted. The Company is currently evaluating the impact of the adoption of this ASU on its consolidated financial statements.
	In January 2014, the FASB issued ASU No. 2014-04, Receivables (Topic 310): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure, to clarify that an in substance repossession or foreclosure occurs upon either the creditor obtaining legal title to the residential real estate property or 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. The amendments are effective for annual periods, and interim reporting periods within those annual periods, beginning after December 15, 2014. The amendments may be adopted using either a modified retrospective transition method or a prospective transition method and early adoption is permitted. The Company does not expect the adoption of this ASU to have a material impact on its consolidated financial statements.
	In July 2013, the FASB issued ASU No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, to provide guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists thereby reducing diversity in practice. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted. The amendments are to be applied prospectively to all unrecognized tax benefits that exist at the effective date with retrospective application permitted. The adoption of this ASU did not have a material impact on the Company's consolidated financial statements.

These amounts do not include direct costs as explained above. In addition, the following table presents unaudited pro-forma information as if the acquisitions of Community First and South Street had occurred on January 1, 2013 under the “Pro-forma” columns. This pro-forma information gives effect to certain adjustments, including purchase accounting fair value adjustments, amortization of core deposit and other intangibles and related income tax effects and is based on our historical results for the periods presented. Transaction-related costs related to the acquisition are not reflected in the pro-forma amounts. The pro-forma information does not necessarily reflect the results of operations that would have occurred had the Company acquired Community First and South Street at the beginning of 2013. Cost savings are also not reflected in the unaudited pro-forma amounts for three and nine months ended September 30, 2014 and 2013, respectively (dollars in thousands).

[1]	The provision for loan losses includes the "net" provision on covered loans after coverage provided by FDIC loss-share agreements, which totaled $(0.1) million and $(0.3) million for the three and nine months ended September 30, 2014, respectively. This resulted in a decrease in the FDIC indemnification asset of $(0.4) million and $(1.2) million, which is the difference between the net provision on covered loans and the total additions to the allowance for loan losses allocable to the covered loan portfolio of $(0.5) million and $(1.5) million for the three and nine months ended September 30, 2014, respectively.
[2]	The provision for loan losses includes the "net" provision on covered loans after coverage provided by FDIC loss-share agreements, which totaled $0.2 million and $0.6 million for the three and nine months ended September 30, 2013, respectively. This resulted in an increase in the FDIC indemnification asset of $0.9 million and $2.6 million, which is the difference between the net provision on covered loans and the total additions to the allowance for loan losses allocable to the covered loan portfolio of $1.2 million and $3.2 million for the three and nine months ended September 30, 2013.
