Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Nature of Operations and Principles of Consolidation Capital Bank Financial Corp. (“CBF” or the “Company”; formerly known as North American Financial Holdings, Inc.) is a bank holding company incorporated in late 2009 in Delaware and headquartered in North Carolina whose business is conducted primarily through Capital Bank Corporation (“Capital Bank Corporation” or the “Bank”). The Company was incorporated with the goal of creating a regional banking franchise in the southeastern region of the United States through organic growth and acquisitions of other banks, including failed, underperforming and undercapitalized banks. CBF has raised $955.6 million to make acquisitions through a series of private placements and an initial public offering of its common stock. Since inception, CBF has acquired seven depository institutions, including the assets and certain deposits from failed banks. CBF has a total of 151 full service banking offices located in Florida, North and South Carolina, Tennessee and Virginia. Through its branches CBF offers a wide range of commercial and consumer loans and deposits, as well as ancillary financial services. The accompanying unaudited Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and Regulation S-X. Accordingly, they do not include all of the information and disclosures required by U.S. GAAP for complete financial statement presentation. In the opinion of management, all adjustments consisting of normal recurring accruals and disclosures considered necessary for a fair interim presentation have been included. All significant inter-company accounts and transactions have been eliminated in consolidation. For further information, refer to the Company’s Consolidated Financial Statements and notes thereto included in the Company’s annual report on Form 10-K for the fiscal year ended December 31, 2015. Use of Estimates and Assumptions To prepare financial statements in conformity with U. S. GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as presented in the financial statements. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ. Recent Accounting Pronouncements In March 2016, the Financial Accounting Standard Board (the “FASB”) issued Accounting Standards Update ("ASU") 2016-9, "Compensation—Stock compensation (Topic 718): Improvements to employee share-based payment accounting" which objective is the simplification through the identification, evaluation, and improvement of areas of generally accepted accounting principles (GAAP) for which cost and complexity can be reduced while maintaining or improving the usefulness of the information provided to users of financial statements. The areas for simplification involve several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Some of the areas for simplification apply only to nonpublic entities. The adoption of ASU 2016-9 will be effective for the fiscal year beginning after December 15, 2016. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows. In January 2016, the FASB issued ASU 2016-2, "Leases (Topic 842)" which increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. To meet that objective, the FASB is amending the FASB Accounting Standards Codification and creating Topic 842, Leases. This Update, along with IFRS 16, Leases, are the results of the FASB’s and the International Accounting Standards Board’s (IASB’s) efforts to meet that objective and improve financial reporting. The Boards decided to not fundamentally change lessor accounting with the amendments in this Update. However, some changes have been made to lessor accounting to conform and align that guidance with the lessee guidance and other areas within generally accepted accounting principles (GAAP), such as Topic 606, Revenue from Contracts with Customers. The main difference between previous GAAP and Topic 842 is the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. The adoption of ASU 2016-2 will be effective for the fiscal year beginning after December 15, 2018. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows. In January 2016, the FASB issued ASU 2016-1, "Financial instruments Overall (Subtopic 825-10)" which requires all equity investments to be measured at fair value with changes in the fair value recognized through net income (other than those accounted for under equity method of accounting or those that result in consolidation of the investee). The amendments in this Update also require an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. In addition, the amendments in this Update eliminate the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities and the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet for public business entities. For public business entities, the amendments in ASU 2016-1 are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of ASU 2016-1 is not expected to have a material impact on the Company's consolidated financial position, results of operations and cash flows. In November 2015, the FASB issued ASU 2015-17, "Income taxes (Topic 740)" which requires an entity to separate deferred income tax liabilities and assets into current and noncurrent amounts in a classified statement of financial position. Deferred tax liabilities and assets are classified as current or noncurrent based on the classification of the related asset or liability for financial reporting. Deferred tax liabilities and assets that are not related to an asset or liability for financial reporting are classified according to the expected reversal date of the temporary difference. The amendments in ASU 2015-17 are effective for financial statements issued for annual periods beginning after December 15, 2017, and interim periods within annual periods beginning after December 15, 2018. The adoption of ASU 2015-17 is not expected to have a material impact on the Company's consolidated financial position, results of operations and cash flows. In September 2015, the FASB issued ASU 2015-16, "Business Combinations (Topic 805) - Simplifying the Accounting for Measurement-Period Adjustments". The amendments in ASU 2015-16 require that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendments in ASU 2015-16 require that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The amendments in ASU 2015-16 also require an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. The adoption of ASU 2015-16 is not expected to have a material impact on the Company’s consolidated financial position, results of operations or cash flows. In September 2015, the FASB issued ASU 2015-15, "Interest—Imputation of interest (Subtopic 835-30) - Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements". The amendments in ASU 2015-15, adds SEC paragraphs pursuant to the SEC Staff Announcement at the June 18, 2015 Emerging Issues Task Force (EITF) meeting about the presentation and subsequent measurement of debt issuance costs associated with line-of-credit arrangements. Given the absence of authoritative guidance within ASU 2015-03 for debt issuance costs related to line-of-credit arrangements, the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The adoption of ASU 2015-15 is not expected to have a material impact on the Company’s consolidated financial position, results of operations or cash flows. In August 2015, the FASB issued ASU 2015-14, "Revenue from contracts with customers (Topic 606) - Deferral of the Effective Date". The amendments in ASU 2015-14 establish December 15, 2017 as the effective date of the information related to ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)”h. The Company is currently evaluating ASU 2014-9 to determine the impact on its consolidated financial position, results of operations and cash flows. In April 2015, the FASB issued ASU 2015-3, "Interest - Imputation of interest" (Subtopic 835-30) - Simplifying the Presentation of Debt Issuance Costs". The amendments in ASU 2015-3 require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this Update. The amendments in ASU 2015-3 are effective for financial statements issued for fiscal years beginning after December 31, 2015, and interim periods within those fiscal years. The adoption of ASU 2015-3 did not have a material impact on the Company’s consolidated financial position, results of operations or cash flows. In June 2014, the FASB issued ASU No. 2014-12, “Compensation-Stock Compensation (Topic 718)—Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could be Achieved after the Requisite Service Period”h. ASU 2014-12 provides specific guidance on whether to treat a performance target that could be achieved after the requisite service period as a performance condition that affects vesting or as a nonvesting condition that affects the grant-date fair value of an award. ASU 2014-12 is effective for fiscal years and interim periods beginning after December 15, 2015. The adoption of ASU 2014-12 did not have a material impact on the Company’s consolidated financial position, results of operations or cash flows. In June 2014, the FASB issued ASU 2014-11, "Transfers and Servicing (Topic 860) - Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures". The amendments in ASU 2014-11 change the accounting for repurchase-to-maturity transactions to secured borrowing accounting. For repurchase financing arrangements, the amendments in ASU 2014-11 require separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty, which will result in secured borrowing accounting for the repurchase agreement. The amendments in ASU 2014-11 also require disclosures for certain transactions comprising (1) a transfer of a financial asset accounted for as a sale and (2) an agreement with the same transferee entered into in contemplation of the initial transfer that results in the transferor retaining substantially all of the exposure to the economic return on the transferred financial asset throughout the term of the transaction. The adoption of ASU 2014-11 did not have a material impact on the Company’s consolidated financial position, results of operations or cash flows. In May 2014, the FASB issued ASU 2014-9, "Revenue from Contracts with Customers (Topic 606)". The FASB and the International Accounting Standards Board (the “IASB”) initiated a joint project to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP and IFRS. As a result, the FASB created a new Topic 606, Revenue from Contracts with Customers, which completes the joint effort by the FASB and IASB to improve financial reporting by creating common revenue recognition guidance for U.S. GAAP and IFRS. The core principle of Topic 606 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies the performance obligation. The adoption of ASU 2014-9 is not expected to have a material impact on the Company’s consolidated financial position, results of operations or cash flows.

The majority of unrealized losses are related to the Company’s corporate securities and mortgage-backed securities. The corporate bonds in an unrealized loss position at March 31, 2016 and December 31, 2015 continue to perform and are expected to perform through maturity. Unrealized losses associated with these securities are primarily due to changes in interest rates and market volatility, and the corporate issuers have not experienced significant adverse events that would call into question their ability to repay those debt obligations according to contractual terms. Further, because the Company does not have the intent to sell these corporate bonds and it is more likely than not that it will not be required to sell the securities before their anticipated recovery of their amortized cost bases, the Company does not consider these securities to be other-than-temporarily-impaired as of March 31, 2016 or December 31, 2015. All of the mortgage-backed securities at March 31, 2016 and December 31, 2015 were issued by U.S. government-sponsored entities and agencies, which the government has affirmed its commitment to support. Unrealized losses associated with these securities are attributable to changes in interest rates and illiquidity, and not credit quality, and because the Company does not have the intent to sell these mortgage-backed securities and it is more likely than not that it will not be required to sell the securities before their anticipated recovery, the Company does not consider these securities to be other-than-temporarily impaired at March 31, 2016 or December 31, 2015 . Investment securities having carrying values of approximately $362.4 million and $311.5 million at March 31, 2016 and December 31, 2015 , respectively, were pledged to secure public funds on deposit, securities sold under agreements to repurchase, and for other purposes as required by law.

As of March 31, 2016 , other loans include $42.3 million , $103.3 million and $1.3 million of farm land, state and political subdivision obligations and deposit customer overdrafts, respectively. As of December 31, 2015 , other loans include $42.8 million , $96.2 million and $1.3 million of farm land, state and political subdivision obligations and deposit customer overdrafts, respectively. Covered loans represent loans acquired from the FDIC subject to loss sharing agreements. Covered loans are further broken out into (i) loans acquired with evidence of credit impairment (“Purchased Credit Impaired", "Acquired Impaired", or "PCI Loans”) and (ii) non-PCI loans. Loans originated or purchased by the Company (“New Loans”) and loans acquired through the purchase of Capital Bank Corp. ("CBKN"), Green Bankshares ("GRNB"), Southern Community Financial ("SCMF" or "Southern Community") and TIB Financial ("TIBB"), are not subject to the loss sharing agreements and are classified as “non covered.” Additionally, certain consumer loans acquired through the acquisition of First National Bank of the South, Metro Bank and Turnberry Bank (collectively, the “Failed Banks”) from the FDIC, are specifically excluded from the loss sharing agreements. On March 18, 2016, the Bank entered into an agreement to terminate all existing loss sharing agreements with the FDIC effective January 1, 2016. All rights and obligations of the Bank and the FDIC under these loss sharing agreements have been resolved and terminated under this agreement. Covered loans and OREO that were subject to the loss sharing agreements were reclassified and are presented as non-covered as of March 31, 2016. The Company designates loans as PCI by evaluating both qualitative and quantitative factors. At the time of acquisition, the Company accounted for the PCI loans by segregating each portfolio into loan pools with similar risk characteristics. Over the lives of the acquired PCI loans, the Company continues to estimate cash flows expected to be collected on each loan pool. The Company evaluates, at each balance sheet date, whether its estimates of the present value of the cash flows from the loan pools, determined using the effective interest rates, has decreased, such that the present value of such cash flows is less than the recorded investment of the pool, and if so, recognizes a provision for loan loss in its Consolidated Statements of Income, unless related to non-credit events. Additionally, if the Company has favorable changes in estimates of cash flows expected to be collected for a loan pool such that the then-present value exceeds the recorded investment of that pool, the Company will first reverse any previously established allowance for loan and lease losses for the pool. If such estimate exceeds the amount of any previously established allowance, the Company will accrete future interest income over the remaining life of the pool at a rate which, when used to discount the expected cash flows, results in the then-present value of such cash flows equaling the recorded investment of the pool at the time of the revised estimate. The table below presents a roll forward of accretable yield and income expected to be earned related to PCI loans and the amount of non-accretable difference at the end of the period. Nonaccretable difference represents estimated contractually required payments in excess of estimated cash flows expected to be collected. The accretable yield represents the excess of estimated cash flows expected to be collected over the carrying amount of the PCI loans. Other represents reductions of accretable yield due to non-credit events such as interest rate reductions on variable rate PCI loans and prepayment activity on PCI loans. (Dollars in thousands) Three Months Ended March 31, 2016 March 31, 2015 Accretable Yield Balance at beginning of period $ 208,844 $ 292,633 Accretion of income (20,843 ) (24,840 ) Reclassification from nonaccretable difference 14,937 26,517 Other (7,873 ) (48,201 ) Balance at end of period $ 195,065 $ 246,109 Nonaccretable difference, balance at the end of the period $ 134,060 $ 207,762 The accretable yield is accreted into interest income over the estimated life of the PCI loans using the level yield method. The accretable yield will change due to changes in: • The estimate of the remaining life of PCI loans which may change the amount of future interest income, and possibly principal, expected to be collected; • The estimate of the amount of contractually required principal and interest payments over the estimated life that will not be collected (the nonaccretable difference); and • Indices for PCI loans with variable rates of interest. For PCI loans, the impact of loan modifications is included in the evaluation of expected cash flows for subsequent decreases or increases of cash flows. For variable rate PCI loans, expected future cash flows will be recalculated as the rates adjust over the lives of the loans. At acquisition, the expected future cash flows were based on the variable rates that were in effect at that time.

* Pooled PCI loans are not classified as nonaccrual as they are considered to be accruing because their interest income relates to the accretable yield recognized under accounting for purchased credit-impaired loans and not to contractual interest payments. Credit Quality Indicators The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans as to credit risk. This analysis is performed at origination and upon identification of a material change for all loans, on an annual basis for commercial loans exceeding $0.5 million , and at least quarterly for commercial loans not rated pass. The Company uses the following definitions for risk ratings: • Pass —These loans range from superior quality with minimal credit risk to loans requiring heightened management attention but that are still an acceptable risk and continue to perform as contracted. • 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 paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the 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.

Troubled Debt Restructuring If a borrower is experiencing financial difficulty, the Bank may consider, in certain circumstances, modifying the terms of their loan to maximize collection of amounts due. A troubled debt restructuring (“TDR”) typically involves either a reduction of the stated interest rate of the loan, an extension of the loan’s maturity date(s) with a stated rate lower than the current market rate for a new loan with similar risk, or in limited circumstances, a reduction of the principal balance of the loan or the loan’s accrued interest. Upon modification of a loan, the Bank measures the related impairment as the excess of the recorded investment in the loan over the discounted expected future cash flows. The present value of expected future cash flows is discounted at the loan’s effective interest rate. If the impairment analysis results in a loss, an allowance for loan and lease losses is established for the loan. During the three months ended March 31, 2016 and 2015 , loans modified in TDRs were nominal. Because of the insignificance of the amount and the nature of the modifications, the modifications did not have a material impact on the Company’s Consolidated Financial Statements or on the determination of the allowance for loan and lease losses at March 31, 2016 and 2015 . The Company had loans modified in TDRs with recorded investments of $1.4 million and $2.2 million for the three months ended March 31, 2016 and 2015 , respectively.

Banking and Thrift [Abstract]
FDIC Indemnification Asset	FDIC Indemnification Asset The Company has recorded an indemnification asset related to loss sharing 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 credit losses and workout expenses on these assets which occur prior to the expiration of the loss sharing agreements. These agreements resulted from the purchase of the Failed Banks. The loss sharing agreements consisted of three (one for each Failed Bank) single-family shared-loss agreements and three (one for each Failed Bank) commercial and other loans shared-loss agreements. The single family shared-loss agreements provided for FDIC loss sharing and our reimbursement for recoveries to the FDIC for ten years from July 16, 2010 for single-family residential loans. The commercial shared-loss agreements provided for FDIC loss sharing for five years from July 16, 2010 and our reimbursement for recoveries to the FDIC for eight years from July 16, 2010 for all other covered assets. On March 18, 2016, the Bank entered into an agreement to terminate all existing loss share agreements with the FDIC effective January 1, 2016. All rights and obligations of the Bank and the FDIC under these FDIC loss share agreements have been resolved and terminated under this agreement. The FDIC received $3.0 million as consideration for the early termination of the agreements. The early termination was recorded in the Bank's financial statements by removing the FDIC Indemnification Asset receivable, the FDIC Clawback liability and recording a one-time, pre-tax expense on termination of $9.2 million . The following is a summary of the activity in the FDIC indemnification asset: (Dollars in thousands) Balance, December 31, 2015 $ 6,725 Termination of FDIC loss sharing agreements $ (6,725 ) Balance, March 31, 2016 $ — Balance, December 31, 2014 $ 16,762 Indemnification asset income 77 Amortization of indemnification asset (2,516 ) Cash received on reimbursable losses 872 Balance, March 31, 2015 $ 15,195

Advances from Federal Home Loan Banks [Abstract]
Federal Home Loan Bank Advances and Short-Term Borrowings	Federal Home Loan Bank Advances and Short-Term Borrowings Short-term borrowings include securities sold under agreements to repurchase, cash received from counterparties as collateral for mark-to-market exposure on interest rate swaps and advances from the Federal Home Loan Bank (“FHLB”). The Bank has securities sold under agreements to repurchase with customers. These overnight agreements are collateralized by investment securities of the United States Government or its agencies which are chosen by the Bank. The amounts outstanding at March 31, 2016 and December 31, 2015 were $11.1 million and $11.6 million , respectively, and were collateralized by $22.1 million and $22.9 million , respectively, of agency mortgage-backed securities. The Bank has $5.1 million of short term borrowings related to cash received from counterparties as collateral for mark-to-market exposure on interest rate swaps at March 31, 2016 . The Bank invests in FHLB stock for the purpose of establishing credit lines with the FHLB. The credit availability to the Bank is based on a percentage of the Bank’s total assets as reported on the most recent quarterly financial information submitted to the regulators subject to the pledging of sufficient collateral. The Bank’s collateral with the FHLB consists of a blanket floating lien pledge of the Bank’s residential 1-4 family mortgage, multifamily, home equity line of credit and commercial real estate secured loans. The amounts of eligible collateral at March 31, 2016 and December 31, 2015 provided for incremental borrowing availability of up to $540.3 million and $416.9 million , respectively. At March 31, 2016 and December 31, 2015 , the Bank had $15.4 million and $25.4 million in letters of credit issued by the FHLB respectively, of which $15.2 million and $25.2 million are used as collateral for public funds deposits in lieu of pledging securities to the State of Florida, respectively. The FHLB advances as of March 31, 2016 and December 31, 2015 consisted of the following: (Dollars in thousands) Contractual Outstanding Amount March 31, 2016 Maturity Date Interest Rate as of March 31, 2016 40,000 November 25, 2016 0.44% (1 Month FRC + 2 bps)* 387 November 6, 2017 0.50% 50,000 November 20, 2017 0.42% (1 Month FRC + 2 bps)* 50,000 November 23, 2018 0.42% (1 Month FRC + 2 bps)* 50,000 December 31, 2019 0.39% (1 Month FRC + 2 bps)* 60,000 May 28, 2020 0.44% (1 Month FRC + 2 bps)* 150,000 August 11, 2020 0.44% (1 Month FRC + 2 bps)* 462 February 10, 2026 —% $ 400,849 (Dollars in thousands) Contractual Outstanding Amount December 31, 2015 Maturity Date Interest Rate as of December 31, 2015 $ 60,000 May 19, 2016 0.49% 40,000 November 25, 2016 0.40% (1 Month FRC + 2 bps)* 426 November 6, 2017 0.50% 50,000 November 20, 2017 0.42% (1 Month FRC + 2 bps)* 50,000 November 23, 2018 0.40% (1 Month FRC + 2 bps)* 50,000 December 31, 2019 0.37% (1 Month FRC + 2 bps)* 60,000 May 28, 2020 0.40% (1 Month FRC + 2 bps)* 150,000 August 11, 2020 0.44% (1 Month FRC + 2 bps)* 472 February 10, 2026 —% $ 460,898 (*) FRC = FHLB Fixed Rate Credit interest rate.

Long-Term Borrowings

Debt Disclosure [Abstract]
Long-Term Borrowings	Long-Term Borrowings Subordinated Debentures Through its acquisitions of CBKN, GRNB, SCMF and TIBB, the Company assumed the eleven separate pooled offerings of trust preferred securities listed below. The Company is not considered the primary beneficiary of the trusts (variable interest entities), therefore the trusts are not consolidated in the Company’s Consolidated Financial Statements, but rather the subordinated debentures are presented as liabilities. The trusts consist of wholly-owned statutory trust subsidiaries for the purpose of issuing the trust preferred securities. The trusts used the proceeds from the issuance of trust preferred securities to acquire junior subordinated deferrable interest debentures of the Company. The trust preferred securities essentially mirror the debt securities, carrying a cumulative preferred dividend equal to the interest rate on the debt securities. The debt securities and the trust preferred securities each have 30 -year lives.

Regulatory Capital Requirements [Abstract]
Shareholders' Equity and Minimum Regulatory Capital Requirements	Shareholders’ Equity and Minimum Regulatory Capital Requirements The Company (on a consolidated basis) and the Bank are subject to various regulatory capital requirements administered by federal and state banking agencies. Failure to meet minimum capital requirements results in certain discretionary and required actions by regulators that could have an effect on the Company’s operations. The regulations require the Company and the Bank to meet specific capital adequacy guidelines that involve quantitative measures of assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The Company’s capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. To be considered well capitalized or adequately capitalized as defined under the regulatory framework for prompt corrective action, the Bank must maintain minimum Tier 1 leverage, Tier 1 common, Tier 1 risk-based and Total Risk-based ratios. At March 31, 2016 and December 31, 2015 the Bank maintained capital ratios exceeding the requirement to be considered well capitalized. These minimum ratios along with the actual ratios for the Company and the Bank are presented in the following tables: (Dollars in thousands) Well Capitalized Adequately Capitalized Actual March 31, 2016 Amount Ratio Amount Ratio Amount Ratio Tier 1 Leverage Capital (to Average Assets) CBF Consolidated N/A N/A $ 291,361 ≥ 4.0% $ 910,379 12.5% Bank $ 363,835 ≥ 5.0% 291,068 ≥ 4.0% 807,988 11.1% Tier 1 Common Equity Capital (to Risk-weighted Assets) CBF Consolidated N/A N/A $ 280,855 ≥ 4.5% $ 835,401 13.4% Bank $ 405,383 ≥ 6.5% 280,650 ≥ 4.5% 807,988 13.0% Tier 1 Risk-based Capital (to Risk-weighted Assets) CBF Consolidated N/A N/A $ 374,472 ≥ 6.0% $ 910,379 14.6% Bank $ 498,933 ≥ 8.0% 374,200 ≥ 6.0% 807,988 13.0% Total Risk-based Capital (to Risk-weighted Assets) CBF Consolidated N/A N/A $ 499,297 ≥ 8.0% $ 956,066 15.3% Bank $ 623,666 ≥ 10.0% 498,933 ≥ 8.0% 855,711 13.7% (Dollars in thousands) Well Capitalized Requirement Adequately Capitalized Requirement Actual December 31, 2015 Amount Ratio Amount Ratio Amount Ratio Tier 1 Capital (to Average Assets) CBF Consolidated N/A N/A $ 286,742 ≥ 4.0% $ 908,600 12.7% Bank $ 357,761 ≥ 5.0% $ 286,209 ≥ 4.0% $ 793,722 11.1% Tier 1 Common Equity Capital (to Risk-weighted Assets) CBF Consolidated N/A N/A $ 277,532 ≥ 4.5% $ 840,681 13.6% Bank $ 400,338 ≥ 6.5% $ 277,157 ≥ 4.5% $ 793,722 12.9% Tier 1 Capital (to Risk-weighted Assets) CBF Consolidated N/A N/A $ 370,042 ≥ 6.0% $ 908,600 14.7% Bank $ 492,724 ≥ 8.0% $ 369,543 ≥ 6.0% $ 793,722 12.9% Total Capital (to Risk-weighted Assets) CBF Consolidated N/A N/A $ 493,390 ≥ 8.0% $ 954,065 15.5% Bank $ 615,905 ≥ 10.0% $ 492,724 ≥ 8.0% $ 842,581 13.7% In August 2010, the Bank entered into an Operating Agreement with the Office of the Comptroller of the Currency (the “OCC Operating Agreement”). The OCC Operating Agreement required the Bank to maintain total capital equal to at least 12% of risk-weighted assets, Tier 1 Capital equal to at least 11% of risk-weighted assets and a minimum leverage ratio of 10% (Tier 1 Capital ratio). On August 31, 2015, the OCC terminated this agreement and as a result the Bank is no longer subject to special de novo capital requirements and other restrictions. As of March 31, 2016 and December 31, 2015 , the Company and the Bank met all capital requirements to which they were subject. Tier 1 Capital for the Company includes trust preferred securities to the extent allowable. The OCC Operating Agreement required prior approval from the OCC before paying a dividend to the Company. Dividends that may be paid by a national bank are limited to that bank’s retained net profits for the preceding two years plus retained net profits up to the date of any dividend declaration in the current calendar year. Subsequent to receiving approval from the OCC, the Company received dividends from the bank totaling $199.4 million , $56.0 million and $105.0 million on January 30, 2015, July 15, 2014 and September 24, 2013, respectively. The Company may use these dividends for general corporate purposes including acquisitions, or as a return of capital to shareholders through future share repurchases or dividends. In July 2013, the U.S. banking regulators adopted a final rule which implements the Basel III regulatory capital reforms from the Basel Committee on Banking Supervision, and certain changes required by the Dodd-Frank Act. The final rule established an integrated regulatory capital framework and introduces the “Standardized Approach” for risk-weighted assets, which replaces the Basel I risk-based guidance for determining risk-weighted assets as of January 1, 2015, the date the Company became subject to the new rules. Based on the Company's current capital composition and levels, the Company believes it is in compliance with the requirements as set forth in the final rules. The rules include new risk-based capital and leverage ratios, which will be phased in from 2015 to 2019, and refine the definition of what constitutes “capital” for purposes of calculating those ratios. The new minimum capital level requirements applicable to the Company and the Bank under the final rules are as follows: (i) a new common equity Tier 1 capital ratio of 4.5% ; (ii) a Tier 1 capital ratio of 6% (increased from 4% ); (iii) a total capital ratio of 8% (unchanged from previous rules); and (iv) a Tier 1 leverage ratio of 4% for all institutions. The final rules also establish a “capital conservation buffer” above the new regulatory minimum capital requirements. The capital conservation buffer will be phased-in over four years beginning on January 1, 2016, as follows: the maximum buffer will be 0.625% of risk-weighted assets for 2016, 1.25% for 2017, 1.875% for 2018, and 2.5% for 2019 and thereafter. This will result in the following minimum ratios beginning in 2019: (i) a common equity Tier 1 capital ratio of 7.0% , (ii) a Tier 1 capital ratio of 8.5% , and (iii) a total capital ratio of 10.5% . Under the final rules, institutions are subject to limitations on paying dividends, engaging in share repurchases, and paying discretionary bonuses if its capital level falls below the buffer amount. These limitations establish a maximum percentage of eligible retained income that could be utilized for such actions. As of March 31, 2016 , our capital buffer would be 5.7% ; exceeding the 2.5% 2019 requirement. The final rules also contain revisions to the prompt corrective action framework, which is designed to place restrictions on insured depository institutions if their capital levels begin to show signs of weakness. Under the prompt corrective action requirements, which are designed to complement the capital conservation buffer, insured depository institutions are required to meet the following increased capital level requirements in order to qualify as “well capitalized:” (i) a new common equity Tier 1 capital ratio of 6.5% ; (ii) a Tier 1 capital ratio of 8% (increased from 6% ); (iii) a total capital ratio of 10% (unchanged from previous rules); and (iv) a Tier 1 leverage ratio of 5% (unchanged from previous rules). Dividend Program On April 21, 2016, the Company's board of directors approved a quarterly common dividend of $0.10 per share payable on May 25, 2016, to shareholders of record as of May 11, 2016. S hare Repurchases The Company’s Board of Directors has authorized stock repurchases of up to $400.0 million . Stock repurchases may be made from time to time, on the open market or in privately negotiated transactions. The approved stock repurchase program does not obligate the Company to repurchase any particular amount of shares, and the program may be extended, modified, suspended, or discontinued at any time. During the three months ended March 31, 2016 , the Company repurchased $4.4 million , or 148,300 common shares at an average price of $29.61 . As of March 31, 2016 , the Company has repurchased a total of $298.6 million , or 12,344,660 common shares at an average price of $24.19 per share with $101.4 million remaining under the current board authorized stock repurchase program. The Company accounts for treasury stock using the cost method as a reduction of shareholders’ equity in the accompanying Consolidated Balance Sheets and Statements of Changes in Shareholders’ Equity.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation As of March 31, 2016 , the Company had two compensation plans, the 2010 Equity Incentive Plan ("the "2010 Plan") and the 2013 Omnibus Compensation Plan (the “2013 Plan”) under which shares of its common stock are issuable in the form of stock options, stock appreciation rights, restricted stock, restricted stock units, stock awards, stock bonus awards and other incentive awards. The 2010 Plan was replaced by the 2013 Plan and no further awards may be made pursuant to the 2010 Plan. The 2013 Plan was effective May 22, 2013 and expires on May 22, 2023 , the tenth anniversary of the effective date. The maximum number of shares of common stock of the Company that may be optioned or awarded under this plan is 2,639,000 shares. Awards under this plan may be made to any person selected by the Compensation Committee. The following table summarizes the components and classification of stock-based compensation expense for the three months ended March 31, 2016 and 2015 : (Dollars in thousands) Three Months Ended March 31, 2016 March 31, 2015 Stock options $ 9 $ 184 Restricted stock 308 100 Total stock-based compensation expense $ 317 $ 284 The tax benefit related to stock-based compensation expense arising from restricted stock awards and non-qualified stock options was $0.1 million for the three months ended March 31, 2016 and 2015 , respectively. Stock Options Under the 2010 Plan and 2013 Plan, the exercise price for common stock must equal at least 100% of the fair market value of the stock on the day an option is granted. The exercise price under an incentive stock option granted to a person owning stock representing more than 10% of the common stock must equal at least 110% of the fair market value at the date of grant, and such option is not exercisable after five years from the date the incentive stock option was granted. The Board of Directors may, at its discretion, provide that an option not be exercised in whole or in part for any period or periods of time as specified in the option agreements. Stock options have an expiration of ten years from the date it is granted. Under these plans, 10,000 options were exercised and 30,207 stock options were granted during the three months ended March 31, 2016 . ASC 718 requires the recognition of stock-based compensation expense for the number of awards that are ultimately expected to vest. During the three months ended March 31, 2016 and 2015 , stock based compensation expense was recorded based upon assumptions that the Company would experience no forfeitures. This assumption of forfeitures will be reassessed in subsequent periods based on historical forfeiture rates and may change based on new facts and circumstances. Any changes in assumptions will be accounted for prospectively in the period of change. A summary of the stock option activity for the three months ended March 31, 2016 and 2015 is as follows: Three Months Ended March 31, 2016 March 31, 2015 (Shares in thousands) Shares Weighted Shares Weighted Balance, January 1, 3,075 $ 20.12 3,111 $ 20.26 Granted 30 30.54 — — Exercised (10 ) 18.00 — — Canceled, expired or forfeited — — (1 ) 589.41 Balance, March 31, 3,095 $ 20.23 3,110 $ 20.19 At March 31, 2016 , the weighted average remaining contractual life for outstanding stock options was approximately 4.41 years and the aggregate intrinsic values was $33.6 million for stock options outstanding and exercisable. The intrinsic value for stock options is calculated as the difference between the exercise price of the underlying awards and the market price of the Company’s common stock as of the reporting date. Options outstanding at March 31, 2016 were as follows: (Shares in thousands) Outstanding Options Exercisable Options Range of Exercise Prices Shares Weighted Average Remaining Contractual Life Weighted Average Exercise Price Per Share Shares Weighted Average Exercise Price Per Share $18.00 192 7.14 years $ 18.00 192 $ 18.00 $20.00 2,864 4.18 years 20.00 2,864 20.00 $28.44 - $2,026.00 39 8.09 years 47.86 9 104.61 $18.00 - $2,026.00 3,095 4.41 years $ 20.23 3,065 $ 20.13 Restricted Stock Restricted stock provides the grantee with voting, dividend and anti-dilution rights equivalent to common shareholders, but is restricted from transfer until vested, at which time all restrictions are removed. The restricted stock vests ratably over a three -year period subject to continued employment with the company. The value of the restricted stock is being amortized on a straight-line basis over the implied service periods. There were 185,147 restricted stock awards granted under the 2013 Plan during the three months ended March 31, 2016 .

Income Taxes	Income Taxes A reconciliation of income tax computed at applicable Federal statutory income tax rates to total income tax expense reported for the three months ended March 31, 2016 and 2015 is as follows: (Dollars in thousands) Three Months Ended March 31, 2016 March 31, 2015 Income before income taxes $ 15,620 $ 17,843 Income taxes computed at Federal statutory tax rate 5,467 6,245 Effect of: State taxes (net of federal benefit) 470 452 Tax-exempt interest income, net (170 ) (489 ) Contingent value right expense (CVR) — — Other, net 13 246 Total income tax expense $ 5,780 $ 6,454 The Company uses an estimated annual effective tax rate method of computing its interim tax provision. The effective tax rate is based on forecasted annual pre-tax income, permanent differences and statutory tax rates. For the three months ended March 31, 2016 , the effective income tax rate was 37% . For the three months ended March 31, 2015 , the effective income tax rate was 36% . The change in effective income tax rate was mainly due to lower tax-exempt interest income. The Company and its subsidiaries are subject to U.S. federal income tax, as well as income tax of the states of Florida, South and North Carolina and Tennessee. The net deferred tax assets as of March 31, 2016 and December 31, 2015 were $95.4 million and $105.3 million , respectively. A valuation allowance related to deferred tax assets is required when it is considered more likely than not that all or part of the benefit related to such assets will not be realized. In assessing the need for a valuation allowance, the Company considered both positive and negative evidence in concluding that no valuation allowance was necessary at March 31, 2016 and December 31, 2015 . At March 31, 2016 and December 31, 2015 , the company had $104.9 million and $107.7 million of gross federal net operating loss carryforwards, respectively, which begin to expire after 2029 if unused and are subject to annual cumulative limitation of $10.9 million . At March 31, 2016 and December 31, 2015 , the Company had no unrecognized tax benefits and no amounts recorded for uncertain tax positions.

Fair Value

Fair Value Disclosures [Abstract]
Fair Value	Fair Value FASB guidance on fair value measurements defines fair value, establishes a framework for measuring fair value, and requires fair value disclosures for certain assets and liabilities measured at fair value on a recurring and non-recurring basis. This guidance defines fair value as the exchange price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants in the principal or most advantageous market for the asset or liability. This guidance establishes a fair value hierarchy for disclosure of fair value measurements to maximize the use of observable inputs, that is, inputs that reflect the assumptions market participants would use in pricing an asset or liability based on market data obtained from sources independent of the reporting entity. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity can access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Cash & cash equivalents Cash and cash equivalents include cash on hand and highly-liquid items with an original maturity of three months or less. Accordingly, the carrying amount of such instruments is considered to be a reasonable estimate of fair value. Derivative financial instruments Interest rate swaps are valued by a third party, using models that primarily use market observable inputs, such as yield curves, and are validated by comparison with valuations provided by the respective counterparties. The credit risk associated with derivative financial instruments that are subject to master netting agreements is measured on a net basis by counterparty portfolio. Forward loan sales agreements are based upon the amounts required to settle the contracts. Fair values for commitments to originate loans held for sale are based on fees currently charged to enter into similar agreements. Fair values for fixed-rate commitments consider the difference between current levels of interest rates and the committed rates. Valuation of Investment Securities The fair values of available-for-sale, held-to-maturity and trading securities are determined by: 1) obtaining quoted prices on nationally recognized securities exchanges when available (Level 1 inputs); 2) matrix pricing, which is a mathematical technique widely used in the financial markets to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs); and 3) for certain other debt securities that are not actively traded, custom discounted cash flow modeling (Level 3 inputs). As of March 31, 2016 , the Bank held industrial revenue bonds which are floating rate issues. Since there is no active secondary market for the trading of the bonds, the Company has developed a model to estimate fair value. This model determines an appropriate discount rate for the bonds based on current market rates for liquid corporate bonds with an equivalent credit rating plus an estimated illiquidity factor, and calculates the present value of expected future cash flows using this discount rate. Mortgage Loans Held for Sale Mortgage loans held for sale are carried at the lower of cost or estimated fair value. The fair values of mortgage loans held for sale are based on commitments on hand from investors within the secondary market for loans with similar characteristics. As such, the fair value adjustment for mortgage loans held for sale is classified as nonrecurring Level 2. Valuation of Impaired Loans and Other Real Estate Owned The fair value of collateral dependent impaired loans with specific allocations of the allowance for loan and lease losses and other real estate owned is generally based on recent real estate appraisals and other available observable market information. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. The Company generally uses independent external appraisers in this process who routinely make adjustments to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in a Level 3 classification of the inputs for determining fair value. The Company’s policy is to update appraisals, at a minimum, annually for classified assets, which include collateral dependent loans and OREO. The Company considers appraisals dated within the past 12 months to be current and do not typically make adjustments to such appraisals. In the Company’s process for reviewing third-party prepared appraisals, any differences of opinion on values, assumptions or adjustments to comparable sales data are typically reconciled directly with the independent appraiser prior to acceptance of the final appraisal. Sensitivity to Changes in Significant Unobservable Inputs As discussed above, as of March 31, 2016 , the Company owns industrial revenue bonds, which require recurring fair value estimates categorized within Level 3 of the fair value hierarchy. The significant unobservable inputs used in the fair value measurement of these securities are incorporated in the discounted cash flow modeling valuation. Rates utilized in the modeling of these securities are estimated based upon a variety of factors including the market yields of other non-investment grade corporate debt. Significant changes in any inputs in isolation would result in significantly different fair value estimates.

The methods and assumptions used to estimate fair value are described as follows: Carrying amount is the estimated fair value for cash and cash equivalents, receivable from FDIC, derivatives, noncontractual demand deposits and certain short-term borrowings. As it is not practicable to determine the fair value of Federal Home Loan Bank stock due to restrictions placed on transferability, the estimated fair value is equal to their carrying amount. Security fair values are based on market prices or dealer quotes and, if no such information is available, on the rate and term of the security and information about the issuer including estimates of discounted cash flows when necessary. For fixed rate loans or contractual deposits and for variable rate loans or deposits with infrequent repricing or repricing limits, fair value is based on discounted cash flows using current market rates applied to the estimated life, adjusted for the allowance for loan and lease losses. Fair values for impaired loans are estimated using discounted cash flow analysis or underlying collateral values. Fair value of loans does not necessarily represent exit price. Fair value of long-term debt is based on current rates for similar financing. The fair value of off-balance sheet items that include commitments to extend credit to fund commercial, consumer, real estate construction and real estate-mortgage loans and to fund standby letters of credit is considered nominal.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative and Hedging Activities	Derivative and Hedging Activities The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. The Company may enter into derivative contracts that are intended to economically hedge certain of its risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. During 2015, the company entered into LIBOR-based interest rate swaps with the objective of limiting the variability of interest payment cash flows resulting from changes in the benchmark interest rate LIBOR. These interest rate swaps are designated as cash flow hedges involving the receipt of fixed-rate amounts from a counterparty in exchange for the Company making variable-rate payments over the life of the agreements without exchange of the underlying notional amount. The effective portion of changes in the fair value of the derivatives is recorded in accumulated other comprehensive income and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. Any ineffective portion of a financial instrument’s change in fair value is immediately recognized in earnings. During the next twelve months, the Company estimates that an additional $2.2 million will be reclassified as an increase to interest income from amounts reported in accumulated comprehensive income. During the three months ended March 31, 2016 , no derivative position was designated as cash flow hedges as they were discontinued and none of the gains and losses reported in other comprehensive income were reclassified into earnings as a result of discontinuance of cash flow hedges. The Company also enters into forward loan sales contracts, which are derived from loans held for sale, or in the Company’s pipeline, to enable those borrowers to manage their exposure to interest rate fluctuations. The forward loan sales derivative contracts are not designated as hedging instruments and all changes in fair value are recognized in non-interest income or non-interest expense during the period of change. For the three months ended March 31, 2016 , the Company recorded $24 thousand in non-interest income and $1 thousand in non-interest expense as a result of changes in fair value of derivatives. For the three months ended March 31, 2015 , the company recorded $5 thousand in non-interest income and $47 thousand in non-interest expense as a result of changes in fair value of derivatives. The Company’s derivative instrument contracts at fair value as well as their classification on the Company's balance sheet is presented below: (Dollars in thousands) March 31, 2016 December 31, 2015 Number of instruments Balance Sheet Location Fair Value Notional Fair Value Notional Asset derivatives Derivatives designated as hedging instruments Interest rate swap 4 Other assets $ 5,667 $ 235,000 $ 893 $ 165,000 Derivatives not designated as hedging instruments Forward loan sales contracts 29 Other assets 16 6,316 40 6,967 Total asset derivatives $ 5,683 $ 241,316 $ 933 $ 171,967 Liability derivatives Derivatives designated as hedging instruments Interest rate swap — Other liabilities $ — $ — $ 108 $ 70,000 Derivatives not designated as hedging instruments Forward loan sales contracts 6 Other liabilities 3 1,368 2 1,213 Total liability derivatives $ 3 $ 1,368 $ 110 $ 71,213 The table below presents the effect of the Company's derivative financial instruments on the Consolidated Statements of Income for the three months ended March 31, 2016 : (Dollars in thousands) Three Months Ended March 31, 2016 Derivatives in Cash Flow Hedging Relationship Amount of Gain or (Loss) Recognized in Accumulated OCI on Derivative (Effective Portion) Location of Gain Reclassified from Accumulated OCI into Income (Effective Portion) Amount of Gain Reclassified from Accumulated OCI on Derivative (Effective Portion) Location of Gain or (Loss) Recognized in Income on Derivative (Ineffective Portion) Amount of Gain or (Loss) Recognized in Income on Derivative (Ineffective Portion) Interest rate swap $ 5,526 Interest income $ 644 N/A $ — The table below presents a gross presentation, the effects of offsetting, and a net presentation of the Company's derivatives as of March 31, 2016 : Gross Amounts Not Offset in the Balance Sheets (Dollars in thousands) Gross Amount of Recognized Assets Gross Amount Offset in the Balance Sheets Net Amount of Assets Presented in the Balance Sheets Financial Instruments Cash Collateral Received Net Amount Offsetting of derivative assets: Interest rate swap $ 5,667 $ — $ 5,667 $ — $ 5,061 $ 606 Total $ 5,667 $ — $ 5,667 $ — $ 5,061 $ 606 Offsetting of derivative liabilities: Interest rate swap $ — $ — $ — $ — $ — $ — Total $ — $ — $ — $ — $ — $ — The Company has agreements with each of its derivative counterparties that contain a provision where if the Company defaults on any of its indebtedness or fails to maintain its status as a well capitalized institution, then the Company could also be declared in default on its derivative obligations and could be required to terminate its derivative positions with the counterparty. As of March 31, 2016 , there were no derivatives in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements. The Company is exposed to credit-related losses in the event of nonperformance by the counterparties to these agreements. The Company controls the credit risk of its financial contracts through credit approvals, limits and monitoring procedures and agreements that specify collateral levels to be maintained by the Company and the counterparties. These collateral levels are based on the credit rating of the counterparties.

Accounting Policies [Abstract]
Nature of Operations and Principles of Consolidation	Capital Bank Financial Corp. (“CBF” or the “Company”; formerly known as North American Financial Holdings, Inc.) is a bank holding company incorporated in late 2009 in Delaware and headquartered in North Carolina whose business is conducted primarily through Capital Bank Corporation (“Capital Bank Corporation” or the “Bank”). The Company was incorporated with the goal of creating a regional banking franchise in the southeastern region of the United States through organic growth and acquisitions of other banks, including failed, underperforming and undercapitalized banks. CBF has raised $955.6 million to make acquisitions through a series of private placements and an initial public offering of its common stock. Since inception, CBF has acquired seven depository institutions, including the assets and certain deposits from failed banks. CBF has a total of 151 full service banking offices located in Florida, North and South Carolina, Tennessee and Virginia. Through its branches CBF offers a wide range of commercial and consumer loans and deposits, as well as ancillary financial services. The accompanying unaudited Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and Regulation S-X. Accordingly, they do not include all of the information and disclosures required by U.S. GAAP for complete financial statement presentation. In the opinion of management, all adjustments consisting of normal recurring accruals and disclosures considered necessary for a fair interim presentation have been included. All significant inter-company accounts and transactions have been eliminated in consolidation. For further information, refer to the Company’s Consolidated Financial Statements and notes thereto included in the Company’s annual report on Form 10-K for the fiscal year ended December 31, 2015.
Use of Estimates and Assumptions	To prepare financial statements in conformity with U. S. GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as presented in the financial statements. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ.
Recent Accounting Pronouncements	In March 2016, the Financial Accounting Standard Board (the “FASB”) issued Accounting Standards Update ("ASU") 2016-9, "Compensation—Stock compensation (Topic 718): Improvements to employee share-based payment accounting" which objective is the simplification through the identification, evaluation, and improvement of areas of generally accepted accounting principles (GAAP) for which cost and complexity can be reduced while maintaining or improving the usefulness of the information provided to users of financial statements. The areas for simplification involve several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Some of the areas for simplification apply only to nonpublic entities. The adoption of ASU 2016-9 will be effective for the fiscal year beginning after December 15, 2016. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows. In January 2016, the FASB issued ASU 2016-2, "Leases (Topic 842)" which increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. To meet that objective, the FASB is amending the FASB Accounting Standards Codification and creating Topic 842, Leases. This Update, along with IFRS 16, Leases, are the results of the FASB’s and the International Accounting Standards Board’s (IASB’s) efforts to meet that objective and improve financial reporting. The Boards decided to not fundamentally change lessor accounting with the amendments in this Update. However, some changes have been made to lessor accounting to conform and align that guidance with the lessee guidance and other areas within generally accepted accounting principles (GAAP), such as Topic 606, Revenue from Contracts with Customers. The main difference between previous GAAP and Topic 842 is the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. The adoption of ASU 2016-2 will be effective for the fiscal year beginning after December 15, 2018. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows. In January 2016, the FASB issued ASU 2016-1, "Financial instruments Overall (Subtopic 825-10)" which requires all equity investments to be measured at fair value with changes in the fair value recognized through net income (other than those accounted for under equity method of accounting or those that result in consolidation of the investee). The amendments in this Update also require an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. In addition, the amendments in this Update eliminate the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities and the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet for public business entities. For public business entities, the amendments in ASU 2016-1 are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of ASU 2016-1 is not expected to have a material impact on the Company's consolidated financial position, results of operations and cash flows. In November 2015, the FASB issued ASU 2015-17, "Income taxes (Topic 740)" which requires an entity to separate deferred income tax liabilities and assets into current and noncurrent amounts in a classified statement of financial position. Deferred tax liabilities and assets are classified as current or noncurrent based on the classification of the related asset or liability for financial reporting. Deferred tax liabilities and assets that are not related to an asset or liability for financial reporting are classified according to the expected reversal date of the temporary difference. The amendments in ASU 2015-17 are effective for financial statements issued for annual periods beginning after December 15, 2017, and interim periods within annual periods beginning after December 15, 2018. The adoption of ASU 2015-17 is not expected to have a material impact on the Company's consolidated financial position, results of operations and cash flows. In September 2015, the FASB issued ASU 2015-16, "Business Combinations (Topic 805) - Simplifying the Accounting for Measurement-Period Adjustments". The amendments in ASU 2015-16 require that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendments in ASU 2015-16 require that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The amendments in ASU 2015-16 also require an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. The adoption of ASU 2015-16 is not expected to have a material impact on the Company’s consolidated financial position, results of operations or cash flows. In September 2015, the FASB issued ASU 2015-15, "Interest—Imputation of interest (Subtopic 835-30) - Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements". The amendments in ASU 2015-15, adds SEC paragraphs pursuant to the SEC Staff Announcement at the June 18, 2015 Emerging Issues Task Force (EITF) meeting about the presentation and subsequent measurement of debt issuance costs associated with line-of-credit arrangements. Given the absence of authoritative guidance within ASU 2015-03 for debt issuance costs related to line-of-credit arrangements, the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The adoption of ASU 2015-15 is not expected to have a material impact on the Company’s consolidated financial position, results of operations or cash flows. In August 2015, the FASB issued ASU 2015-14, "Revenue from contracts with customers (Topic 606) - Deferral of the Effective Date". The amendments in ASU 2015-14 establish December 15, 2017 as the effective date of the information related to ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)”h. The Company is currently evaluating ASU 2014-9 to determine the impact on its consolidated financial position, results of operations and cash flows. In April 2015, the FASB issued ASU 2015-3, "Interest - Imputation of interest" (Subtopic 835-30) - Simplifying the Presentation of Debt Issuance Costs". The amendments in ASU 2015-3 require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this Update. The amendments in ASU 2015-3 are effective for financial statements issued for fiscal years beginning after December 31, 2015, and interim periods within those fiscal years. The adoption of ASU 2015-3 did not have a material impact on the Company’s consolidated financial position, results of operations or cash flows. In June 2014, the FASB issued ASU No. 2014-12, “Compensation-Stock Compensation (Topic 718)—Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could be Achieved after the Requisite Service Period”h. ASU 2014-12 provides specific guidance on whether to treat a performance target that could be achieved after the requisite service period as a performance condition that affects vesting or as a nonvesting condition that affects the grant-date fair value of an award. ASU 2014-12 is effective for fiscal years and interim periods beginning after December 15, 2015. The adoption of ASU 2014-12 did not have a material impact on the Company’s consolidated financial position, results of operations or cash flows. In June 2014, the FASB issued ASU 2014-11, "Transfers and Servicing (Topic 860) - Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures". The amendments in ASU 2014-11 change the accounting for repurchase-to-maturity transactions to secured borrowing accounting. For repurchase financing arrangements, the amendments in ASU 2014-11 require separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty, which will result in secured borrowing accounting for the repurchase agreement. The amendments in ASU 2014-11 also require disclosures for certain transactions comprising (1) a transfer of a financial asset accounted for as a sale and (2) an agreement with the same transferee entered into in contemplation of the initial transfer that results in the transferor retaining substantially all of the exposure to the economic return on the transferred financial asset throughout the term of the transaction. The adoption of ASU 2014-11 did not have a material impact on the Company’s consolidated financial position, results of operations or cash flows. In May 2014, the FASB issued ASU 2014-9, "Revenue from Contracts with Customers (Topic 606)". The FASB and the International Accounting Standards Board (the “IASB”) initiated a joint project to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP and IFRS. As a result, the FASB created a new Topic 606, Revenue from Contracts with Customers, which completes the joint effort by the FASB and IASB to improve financial reporting by creating common revenue recognition guidance for U.S. GAAP and IFRS. The core principle of Topic 606 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies the performance obligation. The adoption of ASU 2014-9 is not expected to have a material impact on the Company’s consolidated financial position, results of operations or cash flows.
