Accounting Policies [Abstract]
Basis of presentation	BASIS OF PRESENTATION 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 Carolina, South Carolina, and Virginia. 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. The Company is subject to the rules and regulations of the Federal Reserve Bank. BNC is operating under the banking laws of North Carolina, and is subject to the rules and regulations of the North Carolina Commissioner of Banks and the Federal Deposit Insurance Corporation (“FDIC”). 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, 2014 should be referred to in connection with these unaudited interim consolidated financial statements. Certain amounts in the 2014 consolidated financial statements have been reclassified to conform to 2015 presentation. These reclassifications had no effect on net income, net income 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 April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-03, Simplifying the Presentation of Debt Issuance Costs , which amends the presentation of debt issuance costs in the balance sheet as a direct deduction from the related debt liability. This update affects disclosures related to debt issuance costs but does not affect existing recognition and measurement guidance for these items. ASU 2015-03 is effective for annual and interim periods beginning after December 15, 2015. The Company does not expect the adoption of this ASU to have a material impact on its consolidated financial statements. In February 2015, the FASB issued ASU 2015-02 Consolidation (Topic 810): Amendments to the Consolidation Analysis , which amends the consolidation analysis required under GAAP. The revised guidance amends the consolidation analysis based on certain fee arrangements or relationships to the reporting entity and, for limited partnerships, requires entities to consider the limited partner’s rights relative to the general partner. Although the amendments are expected to result in the deconsolidation of many entities, the Company will need to reevaluate all of its previous consolidation conclusions. ASU 2015-02 is effective for annual and interim periods beginning after December 15, 2015, with early adoption permitted (including during an interim period), provided that the guidance is applied as of the beginning of the annual period containing the adoption date. The Company is currently evaluating the impact the adoption of this ASU will have on its consolidated financial statements. In May 2014, the FASB issued 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. In July 2015, the FASB voted to approve deferring the effective date by one year (i.e., interim and annual reporting periods beginning after December 15, 2017). Early adoption is permitted, but not before the original effective date (i.e., interim and annual reporting periods beginning after December 15, 2016). The ASU may be adopted using either a modified retrospective method or a full retrospective method. The Company is currently evaluating the impact the adoption of this ASU will have 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 adoption of this ASU did not have a material impact on the Company's consolidated financial statements.

Business Combinations [Abstract]
Acquisitions	ACQUISITIONS Pending Acquisition from CertusBank, N.A. Branches On June 1, 2015, BNC entered into a Purchase and Assumption Agreement to acquire seven branches in upstate South Carolina from CertusBank, N.A. BNC will acquire approximately $284 million in customer deposits and approximately $210 million in loans related to this acquisition. BNC will pay approximately $8.5 million for the branches and related assets, par value for the loan portfolio and a premium of 2.75% with respect to the assumed deposits. The Company anticipates that the acquisition will close in the fourth quarter of 2015, subject to customary closing conditions, including regulatory approval. Acquisition of Valley Financial Corporation On July 1, 2015, the Company completed the acquisition of Valley Financial Corporation ("Valley"), the holding company for Valley Bank, pursuant to the terms of the Agreement and Plan of Merger dated November 17, 2014. Under the merger agreement, Valley's shareholders received 1.1081 shares of the Company's voting common stock for each share of Valley common stock owned. The Company is in the process of obtaining third-party valuations to determine the fair value of loans, property and equipment and intangible assets acquired from Valley. 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 June 30, 2015, none of the assets acquired, liabilities assumed or results of operations for Valley are included in the Company’s financial information as of and for the three and six months ended June 30, 2015.

The Company incurred transaction-related costs of $1.2 million and $4.1 million during the three and six months ended June 30, 2015, which were expensed as incurred as a component of non-interest expense. Transaction-related costs primarily included, but were not limited to, severance costs, professional services, data processing fees, marketing and advertising expenses. 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 [Abstract]
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: Three Months Ended June 30, Six Months Ended June 30, 2015 2014 2015 2014 (Dollars in thousands, except per share amounts) Net income $ 11,014 $ 6,133 $ 19,772 $ 12,617 Weighted average participating common shares - basic 32,585,419 28,877,318 32,632,858 28,095,076 Effects of dilutive Stock Rights 67,540 132,597 71,222 136,776 Weighted average participating common shares - diluted 32,652,959 29,009,915 32,704,080 28,231,852 Basic earnings per common share $ 0.34 $ 0.21 $ 0.61 $ 0.45 Diluted earnings per common share $ 0.34 $ 0.21 $ 0.60 $ 0.45 For the three and six months ended June 30, 2015 and 2014, respectively, there were no shares of Stock Rights excluded in computing diluted common shares outstanding.

These securities were 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. The Company recorded a realized gain of $0.2 million on this sale. The Company's intent and ability to hold the remaining held-to-maturity securities was not impacted by this sale.

The Company noted that none of the securities had an unrealized loss of greater than 5% of their carrying value and the Company believes the municipal bond portfolio has a low risk of credit default. The corporate debt securities are issued by well-capitalized and sound financial institutions. The other debt securities are rated above Aa2 by Moody’s and, in the aggregate, had an unrealized loss of approximately 1% of their carrying value. 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, as opposed to credit concerns related to the respective issuers. The equity securities held by the Company in an unrealized loss position at June 30, 2015 consist of publicly-traded common stock of an investment company, as well as preferred stock of a well-capitalized and sound financial institution. The Company concluded there are no concerns about the long-term viability of the issuers. 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 June 30, 2015.

The unpaid principal balance for acquired loans covered under FDIC loss-share agreements was $123.8 million and $140.4 million at June 30, 2015 and December 31, 2014, respectively. On July 1, 2015, the Company’s loss-share agreement related to the non-single family residential mortgage loans acquired from Beach First National Bank (“Beach First”) expired. Accordingly, the Company will bear all future losses on this portfolio of loans. Immediately prior to the expiration of the loss-sharing arrangement, the loans in this portfolio had a carrying value of $74.4 million . 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 six months ended June 30, 2015 and the year ended December 31, 2014: 2015 2014 Accretable Yield Carrying Value Accretable Yield Carrying Value (Dollars in thousands) Balance at beginning of period $ (2,213 ) $ 137,459 $ (6,058 ) $ 187,661 Reductions from payments and foreclosures, net — (15,935 ) — (54,489 ) Reclass from non-accretable to accretable yield 599 (598 ) (221 ) 221 Accretion 1,273 1,273 4,066 4,066 Balance at end of period $ (341 ) $ 122,199 $ (2,213 ) $ 137,459 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 substandard status fall within the definition of credit-impaired covered loans. The Company has the ability to borrow funds from the Federal Home Loan Bank (“FHLB”) and from the Federal Reserve Bank. At June 30, 2015 and December 31, 2014, real estate loans with carrying values of $1.15 billion and $1.10 billion , respectively, were pledged to secure borrowing facilities from these institutions. A summary of the changes to the allowance for loan losses, by class of financing receivable, is presented below: For the three months ended June 30, 2015 Commercial real estate Commercial construction Commercial and industrial Leases Residential construction Residential mortgage Consumer and other Total (Dollars in thousands) Allowance for loan losses: Balance March 31, 2015 $ 12,802 $ 3,377 $ 3,116 $ 85 $ 411 $ 9,345 $ 215 $ 29,351 Charge-offs (14 ) (74 ) (24 ) — — (399 ) (210 ) (721 ) Recoveries 375 719 273 — 4 277 109 1,757 Provision (1) (228 ) 1,578 (72 ) 7 48 (1,107 ) 75 301 Change in FDIC indemnification asset (1) 5 (53 ) (38 ) — — 22 11 (53 ) Balance June 30, 2015 $ 12,940 $ 5,547 $ 3,255 $ 92 $ 463 $ 8,138 $ 200 $ 30,635 For the three months ended June 30, 2014 Commercial real estate Commercial construction Commercial and industrial Leases Residential construction Residential mortgage Consumer and other Total (Dollars in thousands) Allowance for loan losses: Balance March 31, 2014 $ 13,518 $ 5,667 $ 3,260 $ 74 $ 244 $ 7,818 $ 299 $ 30,880 Charge-offs (492 ) (1,564 ) (495 ) — — (1,374 ) (72 ) (3,997 ) Recoveries 372 767 309 — 3 506 13 1,970 Provision (2) (965 ) 498 390 (20 ) (87 ) 2,289 35 2,140 Change in FDIC indemnification asset (2) (346 ) (184 ) (133 ) — — (203 ) 2 (864 ) Balance June 30, 2014 $ 12,087 $ 5,184 $ 3,331 $ 54 $ 160 $ 9,036 $ 277 $ 30,129 For the six months ended June 30, 2015 Commercial real estate Commercial construction Commercial and industrial Leases Residential construction Residential mortgage Consumer and other Total (Dollars in thousands) Allowance for loan losses: Balance December 31, 2014 $ 12,685 $ 4,311 $ 3,226 $ 103 $ 570 $ 9,313 $ 191 $ 30,399 Charge-offs (1,560 ) (80 ) (109 ) — — (687 ) (266 ) (2,702 ) Recoveries 552 1,493 486 — 34 469 120 3,154 Provision (1) 1,345 264 (278 ) (11 ) (144 ) (912 ) 147 411 Change in FDIC indemnification asset (1) (82 ) (441 ) (70 ) — 3 (45 ) 8 (627 ) Balance June 30, 2015 $ 12,940 $ 5,547 $ 3,255 $ 92 $ 463 $ 8,138 $ 200 $ 30,635 For the six months ended June 30, 2014 Commercial real estate Commercial construction Commercial and industrial Leases Residential construction Residential mortgage Consumer and other Total (Dollars in thousands) Allowance for loan losses: Balance December 31, 2013 $ 14,752 $ 6,738 $ 3,137 $ 56 $ 213 $ 7,730 $ 249 $ 32,875 Charge-offs (2,078 ) (3,144 ) (1,749 ) — — (2,438 ) (164 ) (9,573 ) Recoveries 510 1,316 422 — 13 648 22 2,931 Provision (2) (898 ) 697 1,590 (2 ) (60 ) 3,238 136 4,701 Change in FDIC indemnification asset (2) (199 ) (423 ) (69 ) — (6 ) (142 ) 34 (805 ) Balance June 30, 2014 $ 12,087 $ 5,184 $ 3,331 $ 54 $ 160 $ 9,036 $ 277 $ 30,129 (1) The provision for loan losses includes the "net" provision on covered loans after coverage provided by FDIC loss-share agreements, which totaled $0 and $ (0.2) million for the three and six months ended June 30, 2015, respectively. This resulted in a decrease in the FDIC indemnification asset of $0.1 million and $0.6 million , which is the difference between the net provision on covered loans and the total reduction to the allowance for loan losses allocable to the covered loan portfolio of $(0.1) million and $(0.8) million for the three and six months ended June 30, 2015 , 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 and $(0.3) million for the three and six months ended June 30, 2014 , respectively. This resulted in an increase in the FDIC indemnification asset of $0.9 million and $0.8 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 $(0.9) million and $(1.1) million for the three and six months ended June 30, 2014 , respectively.

The amount of interest income recognized using a cash-basis method of accounting during the period that the loans were impaired was not material. At June 30, 2015 and December 31, 2014, the Company had $1.4 million and $2.5 million , respectively, of consumer mortgage loans secured by residential real estate properties for which foreclosure proceedings were in progress.

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. The Company uses the following definitions for risk ratings: Pass - Loans classified as pass are considered to be a satisfactory credit risk and generally considered to be collectible in full. 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 uncollectable and are in the process of being charged-off, as soon as practicable, once so classified. The following tables present the recorded investment in the Company’s loans by credit quality indicator: Pass Special Mention Substandard Doubtful Loss Total June 30, 2015 (Dollars in thousands) Originated: Commercial real estate $ 1,279,018 $ 42,693 $ 35,437 $ — $ — $ 1,357,148 Commercial construction 292,654 9,907 2,855 — — 305,416 Commercial and industrial 178,041 4,942 4,867 — — 187,850 Leases 24,490 — — — — 24,490 Residential construction 55,266 — 345 — — 55,611 Residential mortgage 420,116 20,810 11,226 — — 452,152 Consumer and other 11,223 570 10 — — 11,803 Total originated 2,260,808 78,922 54,740 — — 2,394,470 Acquired: Commercial real estate 305,001 32,549 26,645 — — 364,195 Commercial construction 27,738 6,149 5,547 — — 39,434 Commercial and industrial 29,135 1,643 955 7 — 31,740 Residential construction 27,424 387 755 — — 28,566 Residential mortgage 333,813 35,853 19,652 556 — 389,874 Consumer and other 4,554 144 30 — — 4,728 Total acquired 727,665 76,725 53,584 563 — 858,537 Total loans $ 2,988,473 $ 155,647 $ 108,324 $ 563 $ — $ 3,253,007 Pass Special Mention Substandard Doubtful Loss Total December 31, 2014 (Dollars in thousands) Originated: Commercial real estate $ 1,100,361 $ 46,935 $ 34,196 $ — $ — $ 1,181,492 Commercial construction 256,987 5,530 3,451 — — 265,968 Commercial and industrial 145,722 3,980 4,430 — — 154,132 Leases 21,100 — — — — 21,100 Residential construction 42,806 143 349 — — 43,298 Residential mortgage 407,319 20,946 11,335 — — 439,600 Consumer and other 10,331 428 92 — — 10,851 Total originated 1,984,626 77,962 53,853 — — 2,116,441 Acquired: Commercial real estate 342,240 35,816 25,531 85 — 403,672 Commercial construction 36,346 5,910 6,320 92 — 48,668 Commercial and industrial 36,039 644 1,482 35 — 38,200 Residential construction 28,833 — 1,021 — — 29,854 Residential mortgage 370,523 36,098 24,616 1,581 — 432,818 Consumer and other 5,256 159 30 — — 5,445 Total acquired 819,237 78,627 59,000 1,793 — 958,657 Total loans $ 2,803,863 $ 156,589 $ 112,853 $ 1,793 $ — $ 3,075,098 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 or extended interest-only payments and term extensions outside of normal underwriting guidelines. 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 as 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.

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 on April 9, 2010 and Blue Ridge Savings Bank on October 14, 2011. Each loss-sharing arrangement consists of one single family residential mortgage loan agreement and one non-single family residential loan agreement. The non-single family residential loan loss-share agreements provide for FDIC loss-sharing to the end of the fiscal quarter five years from the purchase date and reimbursement to the FDIC to the end of the fiscal quarter eight years from the purchase date. The single family residential mortgage loan loss-share agreements provide for FDIC loss-sharing and reimbursement for recoveries to the FDIC to the end of the fiscal quarter ten years from the purchase date. On July 1, 2015, the Company’s loss-share agreement related to the non-single family residential mortgage loans of Beach First expired. Accordingly, the Company will bear all future losses on this portfolio of loans and foreclosed real estate. Immediately prior to the expiration of the loss-sharing arrangement, the loans in this portfolio had a carrying value of $74.4 million and the foreclosed real estate in this portfolio had a carrying value of $0.5 million . The following table presents activity for the FDIC indemnification asset for the six months ended June 30, 2015 and the year ended December 31, 2014: 2015 2014 (Dollars in thousands) Balance at beginning of period $ 5,097 $ 16,886 Accretion of present value discount, net 152 1,061 Post-acquisition adjustments 1,122 (2,920 ) Receipt of payments from FDIC (2,163 ) (9,930 ) Balance at end of period $ 4,208 $ 5,097 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 other real estate owned ("OREO") change.

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. The Company entered into an interest rate swap transaction with a notional amount of $125 million , which 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. The Company receives interest at the one-month LIBOR rate and pays a fixed interest rate under the terms of the swap agreement. The termination date of the swap agreement is March 18, 2019 . Derivatives Not Designated as Hedges The Company utilizes derivative financial instruments, which may include 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 June 30, 2015 and December 31, 2014 , the Company had notional amounts of $35.7 million and $34.7 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: June 30, 2015 December 31, 2014 Notional Amount Balance Sheet Location Fair Value Notional Amount Balance Sheet Location Fair Value (Dollars in thousands) Derivative assets: Derivatives not designated as hedging instruments: Interest rate swaps $ 35,688 Other assets $ 753 $ 34,692 Other assets $ 723 Derivative liabilities: Derivatives designated as hedging instruments: Interest rate swap $ 125,000 Accrued expenses and other liabilities $ 1,052 $ 125,000 Accrued expenses and other liabilities $ 308 Derivatives not designated as hedging instruments: Interest rate swaps $ 35,688 Accrued expenses and other liabilities $ 753 $ 34,692 Accrued expenses and other liabilities $ 723 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: Gross Amounts Not Offset in the Consolidated Balance Sheets Gross Amount Recognized Gross Amounts Offset in the Consolidated Balance Sheets Net Amounts Presented in the Consolidated Balance Sheets Financial Instruments Collateral Held/Pledged Net (Dollars in thousands) June 30, 2015 Derivative assets $ 753 $ — $ 753 $ — $ — $ 753 Derivative liabilities 1,805 — 1,805 — 1,805 — Total derivative instruments $ 2,558 $ — $ 2,558 $ — $ 1,805 $ 753 December 31, 2014 Derivative assets $ 723 $ — $ 723 $ — $ — $ 723 Derivative liabilities 1,031 — 1,031 — 1,031 — Total derivative instruments $ 1,754 $ — $ 1,754 $ — $ 1,031 $ 723 The Company has recorded a net loss of $0.7 million , net of tax, as accumulated other comprehensive income at June 30, 2015 associated with cash flow hedging instruments and expects $1.4 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, net of tax: Three Months Ended June 30, Six Months Ended June 30, 2015 2014 2015 2014 (Dollars in thousands) Amount of net gains (losses) recorded in OCI (effective portion) $ 348 $ (1,044 ) $ (468 ) $ (1,620 ) Amount of net losses reclassified from OCI to earnings (1) — — — 286 (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 six months ended June 30, 2015 and 2014 , respectively. 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 June 30, 2015 , the aggregate fair value of derivative instruments with credit-risk-related contingent features that were in a net liability position was $1.8 million , for which the Company has posted collateral with a fair value of $5.2 million .

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. The following tables present information about certain assets and liabilities measured at fair value on a recurring basis: Total Measured at Fair Value Fair Value Measured Using Description Level 1 Level 2 Level 3 (Dollars in thousands) June 30, 2015 Assets: Investment securities available-for-sale: U.S. Government agencies $ 18,556 $ — $ 18,556 $ — State and municipals 171,242 — 171,242 — Corporate debt securities 17,996 — 17,996 — Other debt securities 74,579 — 74,579 — Equity securities 11,564 781 10,783 — Mortgage-backed securities: Residential government sponsored 24,557 — 24,557 — Other government sponsored 1,586 — 1,586 — Total investment securities available-for-sale 320,080 781 319,299 — Derivative instruments: Interest rate swap - not designated 753 — 753 — Total derivative instruments 753 — 753 — Total assets measured at fair value on a recurring basis $ 320,833 $ 781 $ 320,052 $ — Liabilities: Interest rate swap - cash flow hedge $ 1,052 $ — $ 1,052 — Interest rate swap - not designated 753 — 753 — Total liabilities measured at fair value on a recurring basis $ 1,805 $ — $ 1,805 $ — Total Measured at Fair Value Fair Value Measured Using Description Level 1 Level 2 Level 3 (Dollars in thousands) December 31, 2014 Assets: Investment securities available-for-sale: U.S. Government agencies $ 17,888 $ — $ 17,888 $ — State and municipals 188,935 — 188,935 — Corporate debt securities 13,615 — 13,615 — Other debt securities 12,566 — 12,566 — Equity securities 5,909 676 5,233 — Mortgage-backed securities: Residential government sponsored 28,274 — 28,274 — Other government sponsored 2,103 — 2,103 — Total investment securities available-for-sale 269,290 676 268,614 — Derivative instruments: Interest rate swap - not designated 723 — 723 — Total derivative instruments 723 — 723 — Total assets measured at fair value on a recurring basis $ 270,013 $ 676 $ 269,337 $ — Liabilities: Interest rate swap - cash flow hedge $ 308 $ — $ 308 $ — Interest rate swap - not designated 723 — 723 — Total liabilities measured at fair value on a recurring basis $ 1,031 $ — $ 1,031 $ — 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: Total Measured at Fair Value Fair Value Measured Using Description Level 1 Level 2 Level 3 (Dollars in thousands) June 30, 2015 Loans held for sale $ 36,315 $ — $ 36,315 $ — Impaired loans 183,561 — — 183,561 Other real estate owned 33,008 — — 33,008 Total assets measured at fair value on a nonrecurring basis $ 252,884 $ — $ 36,315 $ 216,569 December 31, 2014 Loans held for sale $ 37,280 $ — $ 37,280 $ — Impaired loans 190,247 — — 190,247 Other real estate owned 42,531 — — 42,531 Total assets measured at fair value on a nonrecurring basis $ 270,058 $ — $ 37,280 $ 232,778 The following table presents the valuation and unobservable inputs for Level 3 assets and liabilities measured at fair value on a nonrecurring basis at June 30, 2015: Description Fair Value (in thousands) Valuation Methodology Unobservable Inputs Range of Inputs Impaired loans $ 183,561 Appraised value Discount to reflect current market conditions and ultimate collectability 0% - 20% Other real estate owned $ 33,008 Appraised value Discount to reflect current market conditions 0% - 20% 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.

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.

Commitments and Contingencies Disclosure [Abstract]
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 following table presents the outstanding off-balance sheet financial instruments whose contract amounts represent potential credit risk: June 30, 2015 December 31, 2014 (Dollars in thousands) Commitments under unfunded loans and lines of credit $ 747,893 $ 663,137 Letters of credit 4,266 6,607 Unused credit card lines 4,132 4,512 In addition to the above noted credit commitments, the Company has committed to invest up to $8.8 million in limited partnership interests of unconsolidated entities, of which $5.6 million was unfunded at June 30, 2015 and December 31, 2014, respectively. 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.

At June 30, 2015, 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"). The 2013 Omnibus Plan and the KeySource Plans are the only plans that are available for future grants. At June 30, 2015, the Company had 128,683 Rights issued under the 2006 Omnibus Plan, 432,981 Rights issued and 949,007 Rights available for grants or awards under the 2013 Omnibus Plan, and 130,959 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 six months ended June 30, 2015 . A summary of the Company’s stock option activity for the six months ended June 30, 2015 is presented below: Shares Weighted Average Exercise Price per Share Weighted Average Remaining Contractual Term (Years) Aggregate Intrinsic Value (Dollars in thousands, except per share amounts) Outstanding at December 31, 2014 337,778 $ 11.37 Exercised 170,826 12.14 Forfeited or expired — — Outstanding at June 30, 2015 166,952 $ 10.57 2.35 $ 1,463 Exercisable at June 30, 2015 166,928 $ 10.57 2.35 $ 1,463 Share options expected to vest 24 $ 4.77 0.01 $ 344 The related compensation expense recognized for stock options was immaterial for the six months ended June 30, 2015 and 2014 , respectively.

Basis of Presentation (Policies)	6 Months Ended

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, 2014 should be referred to in connection with these unaudited interim consolidated financial statements.
Reclassifications	Certain amounts in the 2014 consolidated financial statements have been reclassified to conform to 2015 presentation. These reclassifications had no effect on net income, net income 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 April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-03, Simplifying the Presentation of Debt Issuance Costs , which amends the presentation of debt issuance costs in the balance sheet as a direct deduction from the related debt liability. This update affects disclosures related to debt issuance costs but does not affect existing recognition and measurement guidance for these items. ASU 2015-03 is effective for annual and interim periods beginning after December 15, 2015. The Company does not expect the adoption of this ASU to have a material impact on its consolidated financial statements. In February 2015, the FASB issued ASU 2015-02 Consolidation (Topic 810): Amendments to the Consolidation Analysis , which amends the consolidation analysis required under GAAP. The revised guidance amends the consolidation analysis based on certain fee arrangements or relationships to the reporting entity and, for limited partnerships, requires entities to consider the limited partner’s rights relative to the general partner. Although the amendments are expected to result in the deconsolidation of many entities, the Company will need to reevaluate all of its previous consolidation conclusions. ASU 2015-02 is effective for annual and interim periods beginning after December 15, 2015, with early adoption permitted (including during an interim period), provided that the guidance is applied as of the beginning of the annual period containing the adoption date. The Company is currently evaluating the impact the adoption of this ASU will have on its consolidated financial statements. In May 2014, the FASB issued 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. In July 2015, the FASB voted to approve deferring the effective date by one year (i.e., interim and annual reporting periods beginning after December 15, 2017). Early adoption is permitted, but not before the original effective date (i.e., interim and annual reporting periods beginning after December 15, 2016). The ASU may be adopted using either a modified retrospective method or a full retrospective method. The Company is currently evaluating the impact the adoption of this ASU will have 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 adoption of this ASU did not have a material impact on the Company's consolidated financial statements.
