Summary of Significant Accounting Policies [Abstract]	'
Organization	'
	BNC Bancorp (the “Company”) is a bank holding company for Bank of North Carolina (“BNC”), a wholly-owned subsidiary, headquartered in High Point, North Carolina. BNC is a full service commercial bank providing commercial banking services tailored to the particular banking needs of the communities it serves in North and South Carolina. BNC's primary source of revenue is derived from loans to customers, who are predominantly individuals and small to medium size businesses in BNC's market areas.
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, 2012 should be referred to in connection with these unaudited interim consolidated financial statements.
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.
Reclassifications	'
	Reclassifications
	Certain amounts in the 2012 consolidated financial statements have been reclassified to conform to the 2013 presentation. The reclassifications had no effect on net income, net income available to common shareholders or shareholders' equity as previously reported.
Recently Adopted and Issued Accounting Standards	'
	Recently Adopted and Issued Accounting Standards
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-10, Derivatives and Hedging (Topic 815): Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes (“ASU 2013-10”) to provide guidance on the risks that are permitted to be hedged in a fair value or cash flow hedge. Among those risks for financial assets and financial liabilities is the risk of changes in a hedged item's fair value or a hedged transaction's cash flows attributable to changes in the designated benchmark interest rate (referred to as interest rate risk). The provisions were effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013. The Company does not expect the adoption of this ASU to have a material impact on the Company's 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 (“ASU 2013-11”) 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 in ASU 2013-11 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 Company does not expect the adoption of this ASU to have a material impact the Company's consolidated financial statements.
	In February 2013, the FASB issued ASU No. 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. This ASU requires that companies present either in a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source (e.g., the release due to cash flow hedges from interest rate contracts) and the income statement line items affected by the reclassification (e.g., interest income or interest expense). If a component is not required to be reclassified to net income in its entirety, companies would instead cross reference to the related footnote for additional information. This ASU is effective for fiscal and interim reporting periods beginning after December 15, 2012. The adoption of this ASU did not have a material impact on the Company's consolidated financial statements.
	In October 2012, the FASB issued ASU No. 2012-06, Business Combinations (Topic 805): Subsequent Accounting for an Indemnification Asset Recognized at the Acquisition Date as a Result of a Government-Assisted Acquisition of a Financial Institution, which addresses diversity in practice regarding the subsequent measurement of an indemnification asset in a government-assisted acquisition of a financial institution that includes a loss-sharing agreement. The amendments are effective for interim and annual reporting periods beginning on or after December 15, 2012 with early adoption permitted. The adoption of this ASU did not have a material impact on the Company's consolidated financial statements.
	In December 2011, the FASB issued ASU 2011-11, Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities. Under this update, the Company will be required to disclose both gross information and net information about both instruments and transactions eligible for offset in the statement of financial position and transactions subject to an agreement similar to a master netting arrangement. The scope would include derivatives, sale and repurchase agreements and securities borrowing and securities lending arrangements. This disclosure is intended to enable financial statement users to understand the effect of such arrangements on the Company's financial position. The objective of this update is to support further convergence between U.S. GAAP and International Financial Reporting Standards. In January 2013, the FASB released ASU 2013-01 Balance Sheet (Topic 210): Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities. Under this update, the FASB limited the scope of ASU 2011-11 to items identified in the implementation guidance which include derivatives, sale and repurchase agreements and securities borrowing and securities lending arrangements that are either offset on the balance sheet or subject to an enforceable master netting agreement. Both of these updates are effective for annual reporting periods beginning on or after January 1, 2013. The adoption of this ASU did not have a material impact on the Company's consolidated financial statements.

Acquisitions	'
	Acquisition of Randolph Bank & Trust Company
	On October 1, 2013, the Company completed the acquisition of Randolph Bank & Trust Company (“Randolph”) pursuant to the terms of the Agreement and Plan of Merger dated May 31, 2013. Randolph was a commercial bank with approximately $290 million in assets that served small businesses and professionals and operated six branches in the Piedmont-Triad area of North Carolina. This acquisition aligns with the Company's strategy of growth focused within existing markets. Randolph's branch offices will continue to operate under the Randolph name until systems are converted in early December.
	Randolph shareholders received 0.87 shares of BNC voting common stock for each share of Randolph common stock, or cash in the amount of $10.00 per share. Eighty percent of Randolph common shares were converted into the right to receive BNC voting common stock, while the remaining 20% were converted into the right to receive cash. As part of the closing, Randolph preferred shareholders, including the United States Department of the Treasury (“Treasury”), received cash payments equal to the liquidation value of their preferred shares. The Company paid total consideration of approximately $20.6 million.
	The Company is in the process of obtaining third-party valuations to determine the fair value of loans, property, plant and equipment and intangible assets acquired from Randolph. As a result, it is impracticable to disclose the preliminary purchase price allocation as of the filing date of these unaudited consolidated financial statements.
	As the acquisition closed subsequent to September 30, 2013, none of the assets acquired, liabilities assumed or results of operations for Randolph are included in the Company's financial information as of and for the three and nine months ended September 30, 2013.

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 as of the acquisition date or if the change results from an event that occurred after the date of acquisition.

	Series A Preferred Stock Issued under TARP
	On December 5, 2008, as part of the Treasury's Troubled Asset Relief Program (“TARP”) Capital Purchase Program (“CPP”), the Company issued and sold to the Treasury 31,260 shares of Fixed Rate Cumulative Perpetual Preferred Stock, Series A (the “Series A Preferred Stock”), and a warrant to purchase up to 543,337 shares of the Company's common stock at an exercise price of $8.63 per share.  On August 29, 2012, the Treasury completed the auction and sale of its investment in the Company's Series A Preferred Stock to private investors.  The Company received no proceeds from the auction. On September 19, 2012, the Company repurchased the warrant from the Treasury for approximately $940,000. The warrant has been cancelled.
	On April 29, 2013, the Company redeemed all 31,260 shares of the Series A Preferred Stock that were issued under the Treasury's TARP CPP. The redemption was made using cash on hand and the proceeds of a $30.0 million term loan that was obtained in April 2013. See further discussion of the terms of the loan agreement at Note 9.

Earnings Per Share [Abstract]	'
Earnings Per Share [Text Block]	'
	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, restricted stock awards and the warrant under the Treasury's TARP CPP (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. As discussed in Note 3, the warrant issued in connection with the Treasury's TARP CPP was repurchased by the Company and cancelled in September 2012.
	The Company's basic and diluted earnings per share calculations are presented in the following table (dollars in thousands, except per share data):
			Three Months Ended September 30,				Nine Months Ended September 30,

	For the three and nine months ended September 30, 2013, respectively, there were 71,500 and 390,002 shares of Stock Rights excluded in computing diluted common shares outstanding because the exercise price exceeded the average share value for the periods. For the three and nine months ended September 30, 2012, respectively, there were 455,411 shares of Stock Rights excluded in computing diluted common shares outstanding because the exercise price exceeded the average share value for the periods.

	During the second quarter of 2013, the Company transferred $86.5 million of available-for-sale state and municipal debt securities to the held-to-maturity category, reflecting the Company's intent to hold those securities to maturity. Transfers of investment securities into the held-to-maturity category from the available-for-sale category are made at fair value at the date of transfer. The related $1.2 million of unrealized holding gain that was included in the transfer is retained in other comprehensive income and in the carrying value of the held-to-maturity securities. This amount will be amortized as an adjustment to interest income over the remaining life of the securities. This will offset the impact of amortization of the net premium created in the transfer. There were no gains or losses recognized as a result of this transfer.
	The amortized cost and estimated fair value of investment securities at September 30, 2013, by contractual maturity, are shown below (dollars in thousands). The expected life of mortgage-backed securities will differ from contractual maturities because borrowers may have the right to call or prepay the underlying mortgage loans with or without call or prepayment penalties. For purposes of the maturity table, mortgage-backed securities have been included in maturity groupings based on the contractual maturity.

At September 30, 2013, the unrealized losses relate to 228 state and municipal securities, 19 mortgage-backed securities, five agency securities, three corporate debt securities and one other debt security. Three of the state and municipal securities have been in an unrealized loss position for greater than 12 months. The Company noted all state and municipal securities with an unrealized loss were rated as investment grade at September 30, 2013. 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 (“Freddie Mac”). All the securities with an unrealized loss have been in that position for less than 12 months. The gross unrealized losses reported for the agency securities relate to investment securities issued by Freddie Mac or the United States Small Business Administration. The agency securities with an unrealized loss have been in that position for less than 12 months. The Freddie Mac securities have investment grade ratings. The corporate debt securities are with well-capitalized and sound financial institutions. Two of the corporate debt securities have been in that position for more than 12 months. These securities are all rated as investment grade. The other debt security is backed by a pool of student loan debt. The security has been in that position for less than 12 months and has an investment grade rating.
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 loss for these securities are caused by changes in market interest rates and not credit concerns related to the respective issuers. Based on this analysis, the Company does not consider these investment securities to be other-than-temporarily impaired at September 30, 2013.

	(1) The unpaid principal balance for covered loans was $211.1 million and $272.7 million at September 30, 2013 and December 31, 2012, respectively.
	(2) Amount includes $269.0 million and $347.2 million of acquired, non-covered loans as of September 30, 2013 and December 31, 2012, respectively.
	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. 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.
	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 nonaccretable difference represents cash flows not expected to be collected. The changes in the carrying amount of covered acquired loans and accretable yield for loans receivable for the nine months ended September 30, 2013 and the year ended December 31, 2012 is as follows (dollars in thousands):
		30-Sep-13						31-Dec-12
		Accretable			Carrying			Accretable			Carrying
		Yield			Amount			Yield			Amount
	Balance at beginning of period	$	-12,895		$	248,930		$	-8,387		$	320,033
	Reductions from payments and foreclosures, net		-			-54,337			-			-74,998
	Reclass from non-accretable to accretable yield		-1,545			-			-8,403			-
	Accretion		7,206			7,206			3,895			3,895
	Balance at end of period	$	-7,234		$	201,799		$	-12,895		$	248,930
	The Company has the ability to borrow funds from the Federal Home Loan Bank (“FHLB”) and from the Federal Reserve Bank. At September 30, 2013 and December 31, 2012, real estate loans with carrying values of $681.3 million and $462.4 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, and agricultural loans. Commercial real estate is primarily dependent on successful operation or management of the property. 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. The primary risk associated with multifamily loans is the ability of the income-producing property that collateralizes the loan to produce adequate cash flow to service the debt. High unemployment or generally weak economic conditions 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 and leases
	Each commercial loan or lease is centrally 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. To the extent that the loan or lease is secured by collateral, which is usually personal property or business assets such as inventory or accounts receivable, which is true for the majority of commercial loans and leases, the likely value of the collateral and level of strength the collateral brings to the transaction is evaluated. 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 the Bank serves, as well as risks that are specific to each transaction including demand for products and services, personal events such as disability or change in marital status, and reductions in the value of collateral.
	Residential construction loans
	Residential construction loans are made to individuals and are typically secured by 1-4 family residential property. Significant and rapid declines in real estate values or demand can result in increased difficulty in converting these construction loans to permanent loans. Such a decline in values has led to unprecedented levels of foreclosures and losses within the banking industry. In addition, there has been an increase in the average time houses are on the market for sale.
	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. 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 completely repaid. Over the past two years, the Company has significantly tightened underwriting criteria and requirements for second mortgage and home equity lines of credit. This includes requiring higher credit scores from borrowers and limiting loan-to-value ratios.
	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.  At September 30, 2013, 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 $89.3 million, which represented approximately 98% of the total second liens held by the Company.  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 by obtaining updated credit information on all borrowers from the credit bureaus as part of the overall management of the relationship. If these procedures identify 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. Scheduled monthly interest payments are the only required payments during the term of the line. The full principal amount is due at maturity as a lump-sum balloon payment.  At maturity, home equity loans are re-underwritten based on our current underwriting standards and updated appraisals are generally obtained.  Our underwriting criteria for such loans require the borrowers to qualify as if the loans require principal and interest payments for the complete term of the loans sufficient to fully amortize the loans.  If the borrowers qualify 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. At September 30, 2013, approximately 97% of the home equity lines of credit were still paying interest only. The following table summarizes the maturity dates of our home equity lines of credit as of September 30, 2013 (dollars in thousands):
	2013	$	171
	2014		1,570
	2015		1,316
	2016		3,189
	2017		3,463
	2018		4,392
	Thereafter		99,725
		$	113,826
	Consumer and other loans
	Consumer and other loans include loans secured by personal property such as 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.
	An analysis of the allowance for loan losses for the three and nine months ended September 30, 2013 and 2012, respectively, is as follows (dollars in thousands):

(a) The provision for loan losses includes the "net" provision on covered loans after coverage provided by FDIC loss-share agreements, which totaled $216,000 and $619,000 for the three and nine months ended September 30, 2013, respectively. This resulted in an increase in the FDIC indemnification asset of $937,000 and $2.6 million for the three and nine months ended September 30, 2013, respectively, 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 loans portfolio of $1.2 million and $3.2 million for the three and nine months ended September 30, 2013, respectively.
(b) The provision for loan losses includes the "net" provision on covered loans after coverage provided by FDIC loss-share agreements, which totaled $82,000 and $2.8 million for the three and nine months ended September 30, 2012, respectively. This resulted in an increase in the FDIC indemnification asset of $358,000 and $11.5 million for the three and nine months ended September 30, 2012, respectively, 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 loans portfolio of $440,000 and $14.3 million for the three and nine months ended September 30, 2012, respectively.

For the three and nine months ended September 30, 2013 and 2012, 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, 2013 and 2012, 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.
The following presents the recorded investment in the Company's loans, by credit quality indicator, as of September 30, 2013 and December 31, 2012 (dollars in thousands):

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, 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 non-accrual 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.
The following table provides a summary of loans modified as TDRs at September 30, 2013 and December 31, 2012 (dollars in thousands):

As of September 30, 2013 and December 31, 2012, 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 table presents new TDRs, by modification category, for the three and nine months ended September 30, 2013 and 2012 (dollars in thousands). All balances represent the recorded investment as of the end of the period in which the modification was made.

FDIC Indemnification Asset [Abstract]	'
FDIC Indemnification Asset [TextBlock]	'
	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 acquisition 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 single family residential mortgage loan loss-share agreements provide for FDIC loss sharing and reimbursement for recoveries to the FDIC for ten 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 ten years from these dates. The commercial and other loan and other real estate owned loss-share agreements provide for FDIC loss sharing for five years from the above stated dates, and reimbursement to the FDIC for eight years from the above dates.
	FDIC indemnification asset activity for the three and nine months ended September 30, 2013 and 2012 is summarized as follows (dollars in thousands):
		Three Months Ended September 30,				Nine Months Ended September 30,
		2013		2012		2013		2012

	Balance at end of period	$	32,042	$	56,031	$	32,042	$	56,031
	The FDIC indemnification asset is measured separately from the related covered assets and is initially recorded at fair value. The fair value was estimated using projected cash flows related to the loss-share agreements based on the expected reimbursements for losses and the applicable loss-share percentages. Cash flow projections are reviewed and updated prospectively as loss estimates related to both covered loans and covered OREO change.

Derivative Instruments and Hedging Activities Disclosure [Abstract]	'
Derivatives [Text Block]	'
	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. 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. Under this cash flow hedge relationship, the Company has structured a synthetic cap, where the objective is to offset the effect of interest rate changes, whenever funding rates are higher than the strike rate of the synthetic cap. During the third quarter of 2009, the Company paid $24 million to self-finance the transaction, thus securing a traditional interest rate cap. The maturity date of this interest rate cap is February 16, 2014.
	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 as of the forward-starting date of the swap transaction. The effective date of this interest rate swap is 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.
	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, 2013 and December 31, 2012, the Company had notional amounts of $22.9 million and $18.0 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 fair value of the Company's derivatives as of September 30, 2013 and December 31, 2012 is as follows (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 sheet as of September 30, 2013 and December 31, 2012 is presented in the following tables (dollar amounts in thousands):

	The Company has recorded a net loss of $717,000, net of tax, as accumulated other comprehensive loss at September 30, 2013 associated with cash flow hedging instruments and expects losses of $1.9 million, net of tax, to be reclassified into earnings within the next 12 months. The following table presents the losses 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,
		2013			2012			2013			2012
	Derivatives designated as hedging instruments:
	Amount of net gain (losses) recorded in OCI (effective portion)	$	-599		$	-81		$	1,205		$	-347
	Amount of net loss reclassified from OCI to earnings (1)		1,613			1,236			4,402			3,567
	(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 nine months ended September 30, 2013 and 2012. 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. As of September 30, 2013, the aggregate fair value of derivative instruments with credit-risk-related contingent features that were in a net liability position was $569,000, for which the Company has posted collateral of $1.3 million.

Fair Value Measurements	9 Months Ended

Fair value disclosures [Abstract]	'
Fair value disclosures	'
	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 as of 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 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.
	Below is a table that presents information about certain assets and liabilities measured at fair value on a recurring basis (dollars in thousands):

	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.
	Below is a table that presents 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 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, at the dates indicated are as follows (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.

Off-Balance Sheet Risk1 [Abstract]	'
Disclosure of Off Balance Sheet Risks [Text Block]	'
	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.
	At September 30, 2013 and December 31, 2012, the outstanding off-balance sheet financial instruments whose contract amounts represent potential credit risk are as follows (dollars in thousands):
		September 30,		December 31,
		2013		2012
	Commitments under unfunded loans and lines of credit	$	273,996	$	272,308
	Letters of credit		10,145		12,172
	Unused credit card lines		4,332		4,536
	Commitments to sell loans held for sale		17,732		57,414
	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.
	As a result of the Company's FDIC-assisted acquisition activity, the Company has pending litigation as a result of the Beach First and Blue Ridge acquisitions and could have potential litigation from the Carolina Federal acquisition. Any resulting losses from these proceedings would be covered by the terms of the FDIC's loss-share indemnification agreement.

Share-Based Compensation [Abstract]	'
Share-based Compensation [Text Block]	'
	In May 2013, the Company's shareholders approved the BNC Bancorp 2013 Omnibus Stock Incentive Plan (the “2013 Omnibus Plan”). The Compensation Committee of the BNC Bancorp Board of Directors may grant or award eligible participants with stock options, rights to receive restricted shares of common stock, restricted stock units, stock appreciation rights, and other stock-based awards or any combination of awards (collectively referred to herein as “Rights”). As of May 3013, no further awards were to be granted under the previous BNC Bancorp Omnibus Stock Ownership and Long Term Incentive Plan (the “2006 Omnibus Plan”). At September 30, 2013, the Company had 393,419 grants of Rights issued under the 2006 Omnibus Plan. At September 30, 2013, the Company had 45,500 grants of Rights issued and 1,454,500 Rights available for grants or awards under the 2013 Omnibus Plan.
	On September 14, 2012, the Company merged with KeySource and assumed all of the outstanding and unexercised stock options from KeySource's non-statutory and incentive stock option plans. At September 30, 2013, the Company had 284,219 grants of stock options issued and 35,607 stock options available for issuance related to these 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, 2013.
	A summary of stock option activity for the nine months ended September 30, 2013 is presented below (dollars in thousands, except per share data):
					Weighted

	The related compensation expense recognized for stock option awards was $9,000 and $66,000 for the nine months ended September 30, 2013 and 2012, respectively. Included in the 2012 amount was $55,000 of additional compensation expense related to the excess fair value of the stock options assumed from KeySource. As of September 30, 2013, there was $8,000 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 1.11 years.
	Restricted Stock Awards. A summary of the activity of the Company's non-vested stock awards during the nine months ended September 30, 2013 is presented below
