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 June 2016, the Financial Accounting Standard Board (the “FASB”) issued Accounting Standards Update ("ASU") 2016-13, "Financial Instruments—Credit Losses (Topic 326)". Assets Measured at Amortized Cost—this update requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset. The income statement reflects the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. An entity must use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances. The allowance for credit losses for purchased financial assets with a more-than insignificant amount of credit deterioration since origination (PCD assets) that are measured at amortized cost basis is determined in a similar manner to other financial assets measured at amortized cost basis; however, the initial allowance for credit losses is added to the purchase price rather than being reported as a credit loss expense. Only subsequent changes in the allowance for credit losses are recorded as a credit loss expense for these assets. Interest income for PCD assets should be recognized based on the effective interest rate, excluding the discount embedded in the purchase price that is attributable to the acquirer assessment of credit losses at acquisition. Available-for-Sale Debt Securities—Credit losses relating to available-for-sale debt securities should be recorded through an allowance for credit losses. Available-for-sale accounting recognizes that value may be realized either through collection of contractual cash flows or through sale of the security. Therefore, the amendments limit the amount of the allowance for credit losses to the amount by which fair value is below amortized cost because the classification as available for sale is premised on an investment strategy that recognizes that the investment could be sold at fair value, if cash collection would result in the realization of an amount less than fair value. The allowance for credit losses for purchased available-for-sale securities with a more-than-insignificant amount of credit deterioration since origination is determined in a similar manner to other available-for-sale debt securities; however, the initial allowance for credit losses is added to the purchase price rather than reported as a credit loss expense. Only subsequent changes in the allowance for credit losses are recorded in credit loss expense. Interest income should be recognized based on the effective interest rate, excluding the discount embedded in the purchase price that is attributable to the acquirer’s assessment of credit losses at acquisition. For public business entities that are U.S. Securities and Exchange Commission (SEC) filers, the amendments in this Update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. For all other public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows. In May 2016, the FASB issued ASU 2016-12, "Revenue from Contracts with Customers (Topic 606)". The core principle of the guidance in 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 2 exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (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; (5) Recognize revenue when (or as) the entity satisfies a performance obligation. The amendments in this Update do not change the core principle of the guidance in Topic 606. The amendments in this Update affect the guidance in Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606), which is not yet effective. The effective date and transition requirements for the amendments in this Update are the same as the effective date and transition requirements for Topic 606 (and any other Topic amended by Update 2014-09). Accounting Standards Update No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, defers the effective date of Update 2014-09 by one year. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows. In May 2016, the FASB issued ASU 2016-10, "Revenue from Contracts with Customers (Topic 606)". The core principle of the guidance in 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 apply the following steps: (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 a performance obligation. The amendments in this Update affect the guidance in Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606), which is not yet effective. The effective date and transition requirements for the amendments in this Update are the same as the effective date and transition requirements in Topic 606 (and any other Topic amended by Update 2014-09). Accounting Standards Update 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, defers the effective date of Update 2014-09 by one year. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows. In March 2016, the FASB issued 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 March 2016, the FASB issued ASU 2016-7, "Investments—Equity Method and Joint Ventures (Topic 323)". The amendments in this Update eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-bystep basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments in this Update require that an entity that has an available-forsale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated 2 other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendments in this Update are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The amendments should be applied prospectively upon their effective date to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. Earlier application is permitted. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows. In March 2016, the FASB issued ASU 2016-6, "Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments". The amendments in this Update clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments in this Update is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. For public business entities, the amendments in this Update are effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. 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 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 will impact the accounting for future acquisitions. 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 did not 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.

The majority of unrealized losses are related to the Company’s corporate bonds and mortgage-backed securities. The corporate bonds in an unrealized loss position at June 30, 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 June 30, 2016 or December 31, 2015. All of the mortgage-backed securities at June 30, 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 June 30, 2016 or December 31, 2015 . Investment securities having carrying values of approximately $370.9 million and $311.5 million at June 30, 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 June 30, 2016 , other loans include $39.1 million , $112.5 million and $1.5 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. 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.

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.

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 and six months ended months ended June 30, 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 June 30, 2016 and 2015 . The Company had loans modified in TDRs with recorded investments of $0.1 million and $1.5 million for the three and six months ended months ended June 30, 2016 , respectively. The Company had loans modified in TDRs with recorded investments of $0.4 million and $0.9 million for the three and six months ended months ended June 30, 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, June 30, 2016 $ — Balance, December 31, 2014 $ 16,762 Indemnification asset income 129 Amortization of indemnification asset (5,067 ) Cash received on reimbursable losses (60 ) Balance, June 30, 2015 $ 11,764

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 June 30, 2016 and December 31, 2015 were $10.6 million and $11.6 million , respectively, and were collateralized by $15.2 million and $22.9 million , respectively, of agency mortgage-backed securities. The Bank has $6.2 million of short term borrowings related to cash received from counterparties as collateral for mark-to-market exposure on interest rate swaps at June 30, 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 June 30, 2016 and December 31, 2015 provided for incremental borrowing availability of up to $294.4 million and $416.9 million , respectively. At June 30, 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.

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. The trust preferred securities and the debt securities are callable by the Company or the trust, at their respective option after a period of time, and at varying premiums and sooner in specific events, subject to prior approval by the Federal Reserve Board (“FRB”), if then required. Deferral of interest payments on the trust preferred securities is allowed for up to 60 months without being considered an event of default. The subordinated debentures as of June 30, 2016 and December 31, 2015 consisted of the following: (Dollars in thousands) Carrying Amount Date of Offering Face Amount June 30, 2016 December 31, 2015 Interest Rate as of June 30, 2016 Maturity Date July 31, 2001 $ 5,000 $ 3,988 $ 3,959 4.22 % (3 Month LIBOR + 358 bps) July 31, 2031 July 31, 2001 4,000 2,798 2,764 4.22 % (3 Month LIBOR + 358 bps) July 31, 2031 June 26, 2003 10,000 6,174 6,120 3.73 % (3 Month LIBOR + 310 bps) June 26, 2033 September 25, 2003 10,000 6,745 6,668 3.48 % (3 Month LIBOR + 285 bps) October 8, 2033 December 30, 2003 10,000 5,962 5,906 3.47 % (3 Month LIBOR + 285 bps) December 30, 2033 June 28, 2005 3,000 1,671 1,645 2.33 % (3 Month LIBOR + 168 bps) June 28, 2035 December 22, 2005 10,000 4,796 4,731 2.05 % (3 Month LIBOR + 140 bps) March 15, 2036 December 28, 2005 13,000 6,994 6,884 2.19 % (3 Month LIBOR + 154 bps) March 15, 2036 June 23, 2006 20,000 11,938 11,786 2.18 % (3 Month LIBOR + 155 bps) July 7, 2036 May 16, 2007 56,000 30,230 29,782 2.30 % (3 Month LIBOR + 165 bps) June 15, 2037 June 15, 2007 10,000 5,587 5,532 2.11 % (3 Month LIBOR + 143 bps) September 6, 2037 Total $ 151,000 $ 86,883 $ 85,777 Other Subordinated Debentures At June 30, 2016 , the maturities of long-term borrowings were as follows: (Dollars in thousands) Fixed Rate Floating Rate Total Due in 2016 $ — $ — $ — Due in 2017 — — — Due in 2018 — — — Due in 2019 — — — Due in 2020 — — — Thereafter — 86,883 86,883 Total $ — $ 86,883 $ 86,883

Shareholders' Equity and Minimu

Shareholders' Equity and Minimum Regulatory Capital Requirements	6 Months Ended

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 June 30, 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 June 30, 2016 Amount Ratio Amount Ratio Amount Ratio Tier 1 Leverage Capital (to Average Assets) CBF Consolidated N/A N/A $ 292,824 ≥ 4.0% $ 925,498 12.6% Bank $ 364,866 ≥ 5.0% 291,893 ≥ 4.0% 760,462 10.4% Tier 1 Common Equity Capital (to Risk-weighted Assets) CBF Consolidated N/A N/A $ 285,758 ≥ 4.5% $ 849,863 13.4% Bank $ 412,739 ≥ 6.5% 285,743 ≥ 4.5% 760,462 12.0% Tier 1 Risk-based Capital (to Risk-weighted Assets) CBF Consolidated N/A N/A $ 381,010 ≥ 6.0% $ 925,498 14.6% Bank $ 507,987 ≥ 8.0% 380,990 ≥ 6.0% 760,462 12.0% Total Risk-based Capital (to Risk-weighted Assets) CBF Consolidated N/A N/A $ 508,013 ≥ 8.0% $ 970,784 15.3% Bank $ 634,983 ≥ 10.0% 507,987 ≥ 8.0% 807,784 12.7% (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 June 30, 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 $64.2 million , $199.4 million , $56.0 million and $105.0 million on June 1, 2016, 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 June 30, 2016 , our capital buffer would be 4.7% ; 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 July 21, 2016, the Company's board of directors approved a quarterly common dividend of $0.10 per share payable on August 25, 2016, to shareholders of record as of August 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. As of June 30, 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 June 30, 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 and six months ended months ended June 30, 2016 and 2015 : (Dollars in thousands) Three Months Ended Six Months Ended June 30, 2016 June 30, 2015 June 30, 2016 June 30, 2015 Stock options $ 12 $ 104 $ 21 $ 288 Restricted stock 455 4 763 104 Total stock-based compensation expense $ 467 $ 108 $ 784 $ 392 The tax benefit related to stock-based compensation expense arising from restricted stock awards and non-qualified stock options was $177 thousand and $41 thousand for the three months ended June 30, 2016 and 2015 , respectively and $298 thousand and $150 thousand for the six months ended June 30, 2016 and 2015 . 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, 27,250 options were exercised and 30,207 stock options were granted during the six months ended June 30, 2016 . ASC 718 requires the recognition of stock-based compensation expense for the number of awards that are ultimately expected to vest. During the six months ended June 30, 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 six months ended June 30, 2016 and 2015 is as follows: Six Months Ended June 30, 2016 June 30, 2015 (Shares in thousands) Shares Weighted Shares Weighted Balance, January 1, 3,075 $ 20.12 3,111 $ 20.26 Granted 30 30.54 — — Exercised (27 ) 18.00 — — Canceled, expired or forfeited (2 ) 30.54 (2 ) 372.68 Balance, June 30, 3,076 $ 20.23 3,109 $ 20.12 At June 30, 2016 , the weighted average remaining contractual life for outstanding stock options was approximately 4.47 years and the aggregate intrinsic values was $32.8 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 June 30, 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 $18.00 174 6.89 years $ 18.00 174 $ 18.00 $20.00 2,864 3.93 years 20.00 2,864 20.00 $28.44 - $2,026.00 38 7.85 years 44.73 9 91.01 $18.00 - $2,026.00 3,076 4.47 years $ 18.97 3,047 $ 20.09 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 197,484 restricted stock awards granted under the 2013 Plan during the six months ended June 30, 2016 .

Income Tax Disclosure [Abstract]
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 and six months ended months ended June 30, 2016 and 2015 is as follows: (Dollars in thousands) Three Months Ended Six Months Ended June 30, 2016 June 30, 2015 June 30, 2016 June 30, 2015 Income before income taxes $ 27,729 $ 20,247 $ 43,349 $ 38,090 Income taxes computed at Federal statutory tax rate 9,705 7,086 15,172 13,331 Effect of: State taxes (net of federal benefit) 851 783 1,321 1,235 Tax-exempt interest income, net (311 ) (60 ) (481 ) (549 ) Contingent value right expense (CVR) — (118 ) — (118 ) Other, net 82 (434 ) 95 (188 ) Total income tax expense $ 10,327 $ 7,257 $ 16,107 $ 13,711 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 and six months ended June 30, 2016 , the effective income tax rate was 37% . For the three and six months ended months ended June 30, 2015 , the effective income tax rate was 36% . The change in effective income tax rate was mainly due to an increase in non-deductible expenses and 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 June 30, 2016 and December 31, 2015 were $92.3 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 June 30, 2016 and December 31, 2015 . At June 30, 2016 and December 31, 2015 , the company had $110.5 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 $7.9 million . At June 30, 2016 and December 31, 2015 , the Company had no unrecognized tax benefits and no material 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 June 30, 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 June 30, 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 and Hedging Activiti

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 $2.4 million will be reclassified as an increase to interest income from amounts reported in accumulated comprehensive income. During the six months ended June 30, 2016 , no derivative position designated as cash flow hedges 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. During the second quarter of 2016, the company implemented an interest rate swap program to allow customers to convert variable rate loans to fixed rates. The interest rate swaps are simultaneously offset by interest rate swaps that the Company executes with its derivative counterparties. The changes in the fair value of the swaps offset each other, except for any differences in the credit risk of the counterparties. None of these interest rate swaps are designated or qualify as hedging relationships. As the interest rate swaps associated with this program do not meet hedge accounting requirements, changes in fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. The Company recorded $0.2 million of customer swap fees in non-interest income for the six months ended June 30, 2016. 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.

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 June 2016, the Financial Accounting Standard Board (the “FASB”) issued Accounting Standards Update ("ASU") 2016-13, "Financial Instruments—Credit Losses (Topic 326)". Assets Measured at Amortized Cost—this update requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset. The income statement reflects the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. An entity must use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances. The allowance for credit losses for purchased financial assets with a more-than insignificant amount of credit deterioration since origination (PCD assets) that are measured at amortized cost basis is determined in a similar manner to other financial assets measured at amortized cost basis; however, the initial allowance for credit losses is added to the purchase price rather than being reported as a credit loss expense. Only subsequent changes in the allowance for credit losses are recorded as a credit loss expense for these assets. Interest income for PCD assets should be recognized based on the effective interest rate, excluding the discount embedded in the purchase price that is attributable to the acquirer assessment of credit losses at acquisition. Available-for-Sale Debt Securities—Credit losses relating to available-for-sale debt securities should be recorded through an allowance for credit losses. Available-for-sale accounting recognizes that value may be realized either through collection of contractual cash flows or through sale of the security. Therefore, the amendments limit the amount of the allowance for credit losses to the amount by which fair value is below amortized cost because the classification as available for sale is premised on an investment strategy that recognizes that the investment could be sold at fair value, if cash collection would result in the realization of an amount less than fair value. The allowance for credit losses for purchased available-for-sale securities with a more-than-insignificant amount of credit deterioration since origination is determined in a similar manner to other available-for-sale debt securities; however, the initial allowance for credit losses is added to the purchase price rather than reported as a credit loss expense. Only subsequent changes in the allowance for credit losses are recorded in credit loss expense. Interest income should be recognized based on the effective interest rate, excluding the discount embedded in the purchase price that is attributable to the acquirer’s assessment of credit losses at acquisition. For public business entities that are U.S. Securities and Exchange Commission (SEC) filers, the amendments in this Update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. For all other public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows. In May 2016, the FASB issued ASU 2016-12, "Revenue from Contracts with Customers (Topic 606)". The core principle of the guidance in 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 2 exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (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; (5) Recognize revenue when (or as) the entity satisfies a performance obligation. The amendments in this Update do not change the core principle of the guidance in Topic 606. The amendments in this Update affect the guidance in Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606), which is not yet effective. The effective date and transition requirements for the amendments in this Update are the same as the effective date and transition requirements for Topic 606 (and any other Topic amended by Update 2014-09). Accounting Standards Update No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, defers the effective date of Update 2014-09 by one year. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows. In May 2016, the FASB issued ASU 2016-10, "Revenue from Contracts with Customers (Topic 606)". The core principle of the guidance in 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 apply the following steps: (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 a performance obligation. The amendments in this Update affect the guidance in Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606), which is not yet effective. The effective date and transition requirements for the amendments in this Update are the same as the effective date and transition requirements in Topic 606 (and any other Topic amended by Update 2014-09). Accounting Standards Update 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, defers the effective date of Update 2014-09 by one year. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows. In March 2016, the FASB issued 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 March 2016, the FASB issued ASU 2016-7, "Investments—Equity Method and Joint Ventures (Topic 323)". The amendments in this Update eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-bystep basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments in this Update require that an entity that has an available-forsale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated 2 other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendments in this Update are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The amendments should be applied prospectively upon their effective date to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. Earlier application is permitted. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows. In March 2016, the FASB issued ASU 2016-6, "Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments". The amendments in this Update clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments in this Update is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. For public business entities, the amendments in this Update are effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. 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 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 will impact the accounting for future acquisitions. 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 did not 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.
