Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies 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 (the “Bank”; formerly known as Capital Bank, N.A.). 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 152 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 consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). All significant inter-company accounts and transactions have been eliminated in consolidation. The following is a summary of the more significant accounting policies. Certain prior period amounts have been reclassified to conform to the current period presentation. 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. Cash and Cash Equivalents Cash and cash equivalents include cash on hand and highly-liquid items with an original maturity of three months or less including amounts due from banks, federal funds sold, and interest-bearing deposits at the Federal Home Loan Bank (“FHLB”) and the Federal Reserve Bank of Atlanta (“FRB”). Accordingly, the carrying amount of such instruments is considered to be a reasonable estimate of fair value. Trading Securities Marketable equity securities are recorded on a trade-date basis and are accounted for based on the securities’ quoted market prices from a national securities exchange. Those purchased with the intention of recognizing short-term profits are classified as and included in trading securities on our balance sheet. Both realized and unrealized gains and losses on trading securities are included in noninterest income. Investment Securities and Other than Temporary Impairment Investment securities which may be sold prior to maturity are classified as available-for-sale and are carried at fair value, with unrealized gains and losses reported in other comprehensive income. Other securities such as Federal Home Loan Bank stock are carried at cost, periodically evaluated for impairment and are included in other assets on the balance sheets. Investment securities where the Company has both the intent and ability to hold to maturity are classified as held-to-maturity and reported at amortized cost. Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are amortized using the level-yield method without anticipating prepayments, except for mortgage backed securities where prepayments are anticipated. Gains and losses on sales are realized on the trade date and determined using the specific identification method based on the amortized cost of the security sold. Management regularly reviews each investment security for impairment based on criteria that include the extent to which cost exceeds fair value, the financial health of and specific prospects for the issuer(s) and our ability and intention with regard to holding the security. Management evaluates securities for other-than-temporary impairment (“OTTI”) at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. In determining OTTI under accounting guidance, management considers many factors, including but not limited to: (1) the financial condition and near-term prospects of the issuer, (2) whether the market decline was affected by macroeconomic conditions, and (3) whether the entity has the intent to sell the debt security or more likely than not will be required to sell the debt security before its anticipated recovery. The assessment of whether an OTTI exists involves a high degree of subjectivity and judgment and is based on the information available to management at a point in time. When OTTI is determined to have occurred, the amount of the impairment recognized in earnings depends on whether management intends to sell the security or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis, less any current-period credit loss. If management intends to sell or it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis, less any current-period credit loss, the impairment is required to be recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its fair value at the balance sheet date. If management does not intend to sell the security and it is not more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss, the credit worthiness of the issuer is analyzed to determine if there is a credit component of the unrealized loss that would require recognition in earnings. Impairment identified through this analysis is separated into the amount representing the credit loss and the amount related to all other factors (i.e., changes in market interest rates, liquidity premiums, etc.). The amount of impairment related to the credit loss is determined based on the present value of cash flows expected to be collected and is recognized in earnings. The amount of the impairment related to other factors is recognized in other comprehensive income, net of applicable taxes. The previous amortized cost basis less the OTTI recognized in earnings becomes the new amortized cost basis of the investment. Future declines in the fair value of securities may result in impairment charges which may be material to the financial condition and results of operations of the Company. Loans Held for Sale Certain residential fixed rate mortgage loans originated by the Company are sold to third parties on a servicing released basis. Certain of these sales are subject to temporary recourse provisions. The recourse provisions may require the repurchase of the outstanding balance of loans which default within a limited period of time subsequent to the sale. The recourse periods vary by investor and extend up to seven months subsequent to the sale of the loan. All origination fees are recognized as income at the time of the sale. Mortgage loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or market, as determined by outstanding commitments from investors. Net unrealized losses, if any, are recorded as a valuation allowance and charged to earnings. Purchased Credit-Impaired Loans When it is probable that the Company will not collect all contractual cash flows associated with acquired loans, unless specifically exempt, these acquired loans are accounted for under accounting guidance for purchased credit-impaired (“PCI”) loans. Any Allowance for Loan and Lease Losses (“the Allowance”) previously associated with these loans does not carry over to the Company and is eliminated in the purchase accounting adjustments. The fair value of the PCI loans is then assigned based on the present value of estimated future cash flows including prepayments but exclusive of any loss-sharing arrangements. The excess of the gross cash flows expected to be collected over the present value of cash flows at the acquisition date (i.e., the accretable yield) is accreted into income over the estimated remaining term of the PCI loans using the effective yield method, provided that the timing and amount of future cash flows is reasonably estimable. Accordingly, such loans are not classified as nonaccrual as the accretable yield is reported as interest income. The impact of changes in variable interest rates is recognized prospectively as adjustments to the accretable yield. For further discussion of the Company’s acquisitions and loan accounting, see Note 3. Business Combinations and Acquisitions and Note 5. Loans, respectively. New Loans and Acquired Non-PCI Loans New loans that management has the intent and ability to hold are reported at the principal balance outstanding, net of deferred loan fees and costs, and an allowance for loan and lease losses. Acquired non-PCI loans are initially reported at their acquisition date fair value. Subsequently, acquired non-PCI loans are reported net of amortization or accretion of any applicable acquisition discount or premium and an allowance for loan and lease losses. Interest income on New and non-PCI acquired loans is reported on the interest method and includes amortization of net deferred loan fees, costs and any applicable acquisition discount or premium over the loan term. Amortization of deferred loan fees and costs is based on the contractual lives of the loans and does not include anticipation of prepayments. If the collectability of interest appears doubtful, the loan is classified as nonaccrual. Nonaccrual Loans The majority of loans are placed on nonaccrual status when it is probable that principal or interest is not fully collectible, or generally when principal or interest becomes 90 days past due, whichever occurs first. Certain loans past due 90 days or more may remain on accrual status if management determines that it does not have concern over the collectability of principal and interest and such loans are in the process of collection. Generally, when loans are placed on nonaccrual status, accrued and unpaid interest receivable is reversed against interest income in the current period. Interest payments received thereafter are generally applied as a reduction to the remaining principal balance as long as concern exists as to the ultimate collection of the principal. Loans are generally removed from nonaccrual status when they become current as to both principal and interest and concern no longer exists as to the collectability of principal and interest. The Company’s policies related to when loans are placed on nonaccrual status conform to guidelines prescribed by bank regulatory authorities. Direct Financing Leases Direct financing leases are carried at the aggregate of lease payments receivable and estimated residual value of the leased property, if applicable, less unearned income. Interest income on direct financing leases is recognized over the term of the leases to achieve a constant periodic rate of return on the outstanding investment. Initial direct costs are deferred and amortized over the lease term as a reduction to interest income using the effective interest method. Allowance for Loan and Lease Losses The Company maintains an allowance for loan and lease losses to absorb losses incurred in the loan portfolio. The allowance is based on ongoing, quarterly assessments of the probable estimated incurred losses inherent in the portfolio of loans held for investment. The allowance is increased by the provision for loan and lease losses, which is charged against current period operating results and decreased by the amount of charge offs, net of recoveries. The Company’s methodology for assessing the appropriateness of the allowance consists of several key elements, which include the formulaic allowance and the specific allowance for impaired loans. Management develops and documents its systematic methodology for determining the allowance for loan and lease losses by first dividing its portfolio into segments-commercial real estate, commercial, consumer and other. The Company further divides the portfolio segments into classes and subclasses based on initial measurement attributes, risk characteristics or its method of monitoring and assessing credit risk (such as owner occupied commercial real estate, for which the Company believes risk characteristics and cash flows are aligned with the Commercial class). The classes and subclasses for the Company are as follows: Commercial real estate • Non-owner occupied commercial real estate • Other commercial construction and land • Multifamily commercial real estate • 1-4 family residential construction and land Commercial • Owner occupied commercial real estate • Commercial and industrial • Lease Financing Consumer • 1-4 family residential • HELOC • Junior lien • Other consumer loans • Indirect auto Other • Farmland • Agriculture • All other loans For non-PCI loans, the allowance for loan and lease losses is calculated by applying loss factors to outstanding loans. It is the Company’s policy to use loss factors based on historical loss experience which may be adjusted for significant factors that, in management’s judgment, affect the collectability of the portfolio as of the evaluation date. The Company has limited historical loss experience on newly originated loans and the historical loss information available relating to the portfolios of acquired loans is considered by management to be irrelevant to newly originated loans due to differences in underwriting criteria and loan type. Accordingly, the Company currently is utilizing loss rates from a peer group of comparable banks based on size, portfolio type and geography as the basis for determining loss factors to apply to any outstanding loans. The Company derives the loss factors for all segments from pooled loan loss factors. Such pooled loan loss factors are based on peer group historical net charges. Loan loss factors, which are used in determining the allowance, are adjusted quarterly primarily based upon the changes in the level of historical net charge offs and parameter updates by management. Management estimates probable incurred losses in the portfolio based on a historical loss look-back period. The look-back period is representative of management’s consideration of relevant historical loss experience. Furthermore, based on management’s judgment, the Company’s methodology permits adjustments to any loss factor used in the computation of the allowance for significant factors, which affect the collectability of the portfolio as of the evaluation date, but are not reflected in the loss factors. By assessing the probable estimated incurred losses in the loan portfolio on a quarterly basis, management is able to adjust specific and inherent loss estimates based upon the most recent information that has become available. This includes changing the number of periods that are included in the calculation of the loss factors and adjusting qualitative factors to be representative of the current economic cycle and other factors impacting the portfolio. Generally, for Commercial loans, the Company evaluates individual nonaccrual loans with recorded investment balances greater than or equal to $0.5 million and substandard but accruing loans with recorded investment balances greater than or equal to $1.0 million for impairment. Residential mortgage and consumer loans are generally not individually evaluated for impairment unless they become non-accrual and exceed $0.5 million in recorded investment or represent troubled debt restructuring. Loans are considered impaired when the individual evaluation of current information regarding the borrower’s financial condition, loan collateral, and cash flows indicates that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement, including interest payments. Impaired loans are carried at the lower of the recorded investment in the loan, the present value of expected future cash flows discounted at the loan’s effective rate, the loan’s observable market price, or the fair value of the collateral, if the loan is collateral dependent. Excluded from the impairment analysis are large groups of smaller balance homogeneous loans such as consumer, home equity line, indirect auto and residential mortgage loans, which are evaluated on a pool basis. Loans are charged off in whole or in part when they are considered to be uncollectible. For commercial and agricultural, construction and vacant land and commercial mortgage loans, such evaluations are generally considered for collectability based on borrower financial condition as well as the value of any collateral. For residential mortgage and consumer loans, this evaluation is generally based on past due status as discussed above, as well as an evaluation of borrower creditworthiness and the value of any collateral. Recoveries of amounts previously charged off are recorded as an increase in the allowance for loan and lease losses. Significant risk characteristics considered in estimating the allowance for credit losses include the following: • Commercial and agricultural-industry specific economic trends and individual borrower financial condition; • Construction and vacant land, farmland and commercial mortgage loans-type of property (i.e., residential, commercial, industrial) and geographic concentrations and risks and individual borrower financial condition; and • Residential mortgage, indirect auto and consumer-historical charge-offs and current trends in borrower’s credit, property collateral, and loan characteristics. The allowance for loan and lease losses associated with PCI loans is comprised of an allowance necessary for certain pools of loans. An allowance related to a PCI loan pool is established when the present value of expected cash flows from the loan pool is less than its recorded investment. The amount of the allowance is equal to the difference between these amounts. In calculating the present value of expected cash flows for this purpose, changes in cash flow estimates pursuant to credit factors are isolated from those related to changes in interest rate indices. Any subsequent improvement in the expected cash flows related to the loan pool results in a reduction of any previously established allowance. Any changes in the allowance, including the initial establishment, are recorded in earnings for the current period as a component of the provision for loan losses. Estimates of expected cash flows incorporate assumptions of expected prepayments, probability of default and loss severity given default. Probability of default assumptions are derived from incurred and expected loss data published in third party research reports for commercial, commercial real estate and residential loans. Probability of default assumptions for residential loans are adjusted to incorporate increased risk for historical delinquency occurrence and high loan to collateral value (“LTV”) ratios, and updated borrower credit information. For commercial and commercial real estate loans, probability of default assumptions are based upon loan risk ratings of the Company. Loss severity given default assumptions are developed based upon third party research reports or estimates of current LTV ratios which use real estate price index values for the applicable state or Metropolitan Statistical Area (“MSA”) where available. Foreclosed Assets Assets acquired through, or in lieu of, loan foreclosure or repossession are generally held for sale and are initially recorded at fair value less cost to sell when acquired, establishing a new cost basis. If fair value subsequently declines below the initial recorded value, a valuation allowance is recorded through expense so that the asset is reported at the lower of cost or fair value less cost to sell. If fair value subsequently increases, a reduction of any previous valuation allowance is recorded, which is limited to the total amount of the valuation allowance. Costs incurred after acquisition are generally expensed. FDIC Indemnification Asset Pursuant to purchase and assumption agreements with the FDIC, the Bank has entered into loss share agreements in which 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 during the term of the agreement. An indemnification asset is recorded at fair value at the acquisition date. The indemnification asset is recognized at the same time as the indemnified loans, and measured on the same basis, subject to collectability or contractual limitations. The indemnification asset on the acquisition date reflects the present value of future cash flows expected to be received from the FDIC using an appropriate discount rate which reflects counterparty credit risk. Subsequent to initial recognition, the indemnification asset continues to be measured on the same basis as the related indemnified loans and other real estate owned "OREO" and is impacted by changes in estimated cash flows associated with these loans and foreclosed properties. Deterioration in expected cash flows of the loans are immediately recorded as an adjustment to the allowance for loan and lease losses and would correspondingly result in an increase in the indemnification asset, with the offset recorded through the consolidated statement of income. Improvements in the cash flows of the loans would first result in a reversal of any existing cumulative impairment and related valuation allowance and a corresponding decrease in the indemnification asset. Subsequent to the full reversal of any such valuation allowance, additional improvement in loan cash flows is reflected as an adjustment to yield that is accreted into income over the remaining term of the loans along with increased amortization of the indemnification asset. Such amortization is recognized over the shorter of a) the remaining term of the loans or b) the life of the shared loss agreements. Loss assumptions used for the basis of the indemnified loans are consistent with the loss assumptions used to measure the indemnification asset. Fair value accounting incorporates into the fair value of the indemnification asset an element of the time value of money, which is accreted back into income over the life of the loss sharing agreements. Upon the determination of an incurred loss, the indemnification asset will be reduced by the amount owed by the FDIC. A corresponding claim receivable is recorded until cash is received from the FDIC. Premises and Equipment Land is carried on the balance sheet at its cost. Premises and equipment are reported at cost less accumulated depreciation. For financial reporting purposes, premises and equipment are depreciated using the straight-line method over their estimated useful lives. Expenditures for maintenance and repairs are charged to operations as incurred, while major renewals and betterments are capitalized. For Federal income tax reporting purposes, depreciation is computed using primarily accelerated methods. Goodwill and Other Intangible Assets Goodwill and other intangible assets (including core deposit base premiums, customer relationship intangibles, and mortgage servicing rights) arising from business purchase combinations are initially recorded at fair value. Goodwill and other intangible assets with indefinite useful lives are not amortized and are tested for impairment at least annually as of the first day of our third quarter, or whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Other intangible assets with finite useful lives are amortized over their estimated useful lives to their estimated residual values and tested for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Other intangible assets are considered to be impaired if the undiscounted cash flows from its associated asset group are less than their recorded net book value; if impairment is determined to exist, the asset must be written down to its fair value based upon discounted cash flows in the period in which impairment is determined to exist. Factors considered in the impairment evaluation include but are not limited to fair market value, general market conditions and projections of future operating results. In addition, after evaluating the Company’s structure and components, it has been determined that the Company consists of one reporting unit. Company Owned Life Insurance The Company owns life insurance policies on certain current and former directors and employees of its subsidiaries. These policies are recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement, if applicable. Derivative Instruments and Hedging Activities The Bank manages its interest rate risk position through the use of interest rate derivatives (also referred to as hedging instruments, hedging transactions, or hedges). It is the responsibility of the Board of Directors and our asset liability committee to establish an effective policy for the purpose of using derivatives consistent with the Bank’s underlying interest rate risk strategy, business objectives, level of risk tolerance (such as interest rate risk sensitivity policy limits), and financial capacity. Adherence to these requirements ensure that the Bank performs the proper due diligence prior to obtaining, designating and documenting the hedging instruments and the Bank is in compliance with all applicable laws and regulations and accounting principles generally accepted in the United States. 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. Fair Value of Financial Instruments Fair values of financial instruments are estimated using relevant market information and other assumptions. Fair value estimates include uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect these estimates. Operating Leases Rent expense for the Company’s operating leases is recorded on a straight-line basis over the initial lease term and those renewal periods that are reasonably assured. It is common for lease agreements to contain various provisions for items such as step rent or other escalation clauses and lease concessions, which may offer a period of no rent payment. These types of transactions are recorded into expense on a straight line basis over the minimum lease terms. Certain leases require the Company to pay property taxes, insurance and routine maintenance. Income Taxes The provision for income taxes is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities between periods. Deferred tax assets and liabilities are measured using the balance sheet method. Under this method, deferred tax assets and liabilities are determined based on differences between the carrying amount of balance sheet items and their corresponding tax values. Changes in the deferred tax assets and liabilities represent decreases and increases in the future tax liability due to changes in temporary differences and utilization of net operating loss carryforwards and tax credit carryforwards. Current recognition is given to changes in tax rates and laws. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of benefit that is greater than 50% likely to be realized upon settlement. For tax positions not meeting the “more likely than not” test, no benefit is recorded. If applicable, accrual of penalties and interest related to an unrecognized tax benefit are recorded in income tax expense. 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. As of December 31, 2015 and 2014, management considered the need for a valuation allowance and based upon its assessment of the evidence available at the time of the analysis, concluded that a valuation allowance was not necessary. In addition, management’s assessment of the need for a valuation allowance includes interpretations of tax laws, lapse of statute of limitations and changes in statutory and regulatory guidance. The Company is no longer subject to federal, state and local examinations by tax authorities for years before 2011. Loan Commitments and Related Financial Instruments Loan Commitments and Related Financial instruments include off-balance sheet credit instruments such as commitments to make loans and letters of credit issued to meet customer financing needs. The face amount for these items represents the exposure to loss before considering customer collateral or ability to repay. Such financial instruments are recorded on the balance sheet when they are funded. Securities Purchased Under Agreements to Resell and Securities Sold Under Agreements to Repurchase Securities purchased under agreements to resell and securities sold under agreements to repurchase are accounted for as collateralized lending and borrowing transactions, respectively, and are recorded at the amounts at which the securities were acquired or sold plus accrued interest. The fair value of collateral either received from or provided to a third party to secure these transactions is regularly monitored and additional collateral is obtained, provided or requested to be returned as appropriate. Loss Contingencies, Contingent Value Rights and Loss Share Clawback Liabilities Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Current contingent value rights and FDIC loss share related clawback liabilities are recorded within accrued expenses and other liabilities and periodically remeasured, with any changes in measurement accounted for as non-interest expense. During the first quarter, the Bank completed the early redemption of Southern Community Contingent Valuation Rights (CVR). The accrual balance at December 31, 2015 , 2014 , and 2013, for the clawback liability was $1.5 million , $1.3 million , and $1.0 million , respectively. Related Party Transactions Certain of the directors and executive officers of Capital Bank Corporation, members of their immediate families and entities with which they are associated are deposit and loan customers of the Bank. Total loans outstanding as of December 31, 2015 consisted of the following: (Dollars in thousands) 2015 Balance, January 1 $ 13,062 New loans and advances 23,603 Repayments (14,987 ) Balance, December 31 $ 21,678 Operating Segments While the chief operating decision-makers monitor the revenue streams of the various products and services, the financial services operations are considered by management to be one reportable segment. Operations are managed and financial performance is evaluated on a Company-wide basis. Recent Accounting Pronouncements In January 2016, the Financial Accounting Standard Board (the “FASB”) issued Accounting Standards Update ("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

Accordingly, we recorded an other than temporary impairment of $288 thousand and completely wrote-off this investment which was acquired along with one of our legacy acquisitions. As of December 31, 2015 , the Company’s security portfolio consisted of 131 securities, 45 of which were in an unrealized loss position. The majority of unrealized losses are related to the Company’s mortgage-backed securities. All of the mortgage-backed securities at December 31, 2015 and 2014 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 December 31, 2015 or 2014. Investment securities having carrying values of approximately $311.5 million and $339.0 million at December 31, 2015 and 2014 , 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 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. As of December 31, 2014 , other loans include $41.3 million , $76.9 million and $1.7 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" or "PCI Loans”) and (ii) non-PCI loans. Loans originated or purchased by the Company (“New Loans”) and loans acquired through the purchase of CBKN, GRNB, SCMF and 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. Covered loans and OREO that were subject to the commercial shared-loss agreements which expired during the quarter ending September 30, 2015 were reclassified and are presented as non-covered. The commercial shared-loss agreements provided for FDIC loss sharing for five years and our reimbursement for recoveries to the FDIC for eight years from July 16, 2010. The single family shared-loss agreements provide for FDIC loss sharing and our reimbursement for recoveries to the FDIC for ten years from July 16, 2010. 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 Statement 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 loans and prepayment activity. (Dollars in thousands) Years Ended December 31, 2015 December 31, 2014 December 31, 2013 Accretable Yield Balance at beginning of period $ 292,633 $ 383,775 $ 553,348 New PCI loans purchased — — — Accretion of income (96,330 ) (119,701 ) (161,867 ) Reclassification from nonaccretable difference 91,870 71,626 84,203 Other (79,329 ) (43,067 ) (91,909 ) Balance at end of period $ 208,844 $ 292,633 $ 383,775 Nonaccretable difference, balance at the end of the period $ 138,725 $ 204,033 $ 286,272 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 rates that were in effect at that time. Because of the loss protection provided by the FDIC, the risks of covered loans and foreclosed real estate are significantly different from those assets not covered under loss share agreements. Refer to Note 10 – Other Real Estate Owned for the covered balances of other real estate owned.

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 years ended December 31, 2015 and 2014 , 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 December 31, 2015 and 2014 . The Company had loans modified in TDRs with recorded investments of $3.6 million and $3.8 million for the years ended December 31, 2015 and 2014 , 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 consist 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 provide 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 provide for FDIC loss sharing for five years and our reimbursement for recoveries to the FDIC for eight years from July 16, 2010 for all other covered assets. Covered loans and OREO subject to the commercial shared-loss agreements that expired during the quarter ending September 30, 2015, were $89.3 million and $6.9 million , respectively.

The Company completed its annual goodwill impairment test as of July 1, 2015, by performing a qualitative assessment of goodwill at the reporting unit level to determine whether any indicators of impairment existed. In performing this qualitative assessment, the Company evaluated events and circumstances since the date of the last quantitative impairment test including the results of that test, macroeconomic conditions, banking industry and market conditions, key financial metrics and overall financial performance of the Company. After assessing the totality of the events and circumstances, the Company determined that it was not more likely than not that the fair value of its reporting unit was greater than its carrying amount and, therefore, the first and second steps of the quantitative goodwill impairment test were deemed unnecessary. As of December 31, 2015 , we are not aware of any items or events that would cause a further adjustment to the carrying value of goodwill.

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 collateral pledged 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 December 31, 2015 and 2014 were $11.6 million and $23.4 million and were collateralized by $22.9 million and 34.9 million , of agency mortgage-backed securities, respectively. The Bank has $0.8 million of short term borrowings related to cash collateral that is pledged to the Company for the mark-to-market exposure on interest rate swaps. 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 Company recorded a $1.6 million loss on extinguishment of debt as a result of this prepayment. The repurchase agreements as of December 31, 2014 consisted of the following: (Dollars in thousands) Carrying Amount December 31, 2014 Contractual Amount Maturity Date Contractual Rate $ 10,540 $ 10,000 November 6, 2016 4.75% 10,582 10,000 March 30, 2017 4.50% 10,394 10,000 December 18, 2017 3.79% 10,372 10,000 December 18, 2017 3.72% 10,638 10,000 March 22, 2019 3.56% $ 52,526 $ 50,000 These repurchase agreements had a weighted-average rate of 4.06% at December 31, 2014 and were collateralized by $61.4 million of mortgage-backed securities. Subordinated Debentures Through its acquisitions of CBKN, GRNB, SCMF and TIBB, the Company assumed thirteen separate pooled offerings of trust preferred securities. 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 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 December 31, 2015 and 2014 consisted of the following: (Dollars in thousands) Carrying Amount Date of Offering Face Amount December 31, 2015 December 31, 2014 Interest Rate as of December 31, 2015 Maturity Date July 31, 2001 $ 5,000 $ 3,959 $ 3,900 3.91 % (3 Month LIBOR + 358 bps) July 31, 2031 July 31, 2001 4,000 2,764 2,699 3.91 % (3 Month LIBOR + 358 bps) July 31, 2031 June 26, 2003 10,000 6,120 6,017 3.70 % (3 Month LIBOR + 310 bps) June 26, 2033 September 25, 2003 10,000 6,668 6,516 3.17 % (3 Month LIBOR + 285 bps) October 8, 2033 December 30, 2003 10,000 5,906 5,802 3.18 % (3 Month LIBOR + 285 bps) December 30, 2033 June 28, 2005 3,000 1,645 1,594 2.19 % (3 Month LIBOR + 168 bps) June 28, 2035 December 22, 2005 10,000 4,731 4,607 1.91 % (3 Month LIBOR + 140 bps) March 15, 2036 December 28, 2005 13,000 6,884 6,668 2.05 % (3 Month LIBOR + 154 bps) March 15, 2036 June 23, 2006 20,000 11,786 11,488 1.87 % (3 Month LIBOR + 155 bps) July 7, 2036 May 16, 2007 56,000 29,782 28,904 2.16 % (3 Month LIBOR + 165 bps) June 15, 2037 June 15, 2007 10,000 5,532 5,426 1.88 % (3 Month LIBOR + 143 bps) September 6, 2037 $ 151,000 $ 85,777 $ 83,621 Other Subordinated Debentures On April 1, 2015, the Company prepaid a subordinated promissory note with a fixed interest rate of 10.0% due March 18, 2020 assumed through the acquisition of CBKN.

Employee Benefit Plans

Employee Benefit Plans	12 Months Ended

Postemployment Benefits [Abstract]
Employee Benefit Plans	Employee Benefit Plans The Company maintains the Capital Bank 401(k) Plan that covers all employees who are qualified as to age. An employee may contribute from 1% to 90% of eligible pretax salary subject to limitation under the Internal Revenue Code. The Company may make discretionary contributions to employees’ accounts on an annual basis to employees who are employed as of December 31. The amount of the match is determined annually by the Board of Directors and is subject to change. All employee and discretionary matching contributions are 100% vested. Discretionary matching contributions expensed for each of the years ended December 31, 2015 , 2014 and 2013 were $0.2 million , $0.4 million and $0.4 million respectively. During 2013 and 2012 the SCMF and CBKN, GRNB and TIB plans were merged into the Company’s plan. Prior to their acquisition by the Company, CBKN, GRNB, SCMF and TIBB maintained certain benefit plans for the benefit of their respective employees and directors. Upon acquisition of the companies, the Company assumed the accrued liabilities associated with these plans. The plans have been terminated and no deferrals were made in 2015 or 2014. The amounts accrued under these plans totaled $7.8 million and $6.7 million as of December 31, 2015 and 2014 , respectively. The (income) expense related to the vested benefits was $0.1 million , $(0.8) million and $0.4 million for 2015 , 2014 and 2013 , respectively. In 2013, the Company adopted the Capital Bank Financial Corp. Nonqualified Excess Plan, a nonqualified deferred compensation plan that provides highly compensated employees of the Company, including its executive officers, with the opportunity to elect to defer his or her base salary and performance-based compensation, which upon such election, will be credited to the applicable participant’s deferred compensation account. Each deferred compensation account will be invested in one or more investment funds made available by the Company and selected by the participant. The Company may make discretionary contributions to the individual deferred compensation accounts, with the amount, if any, to be determined annually by the Company. All contributions, both by the participant and the Company, are fully vested at all times. Each deferred compensation account will be paid out in a lump sum upon a participant’s separation from service with the Company, unless another payment event has been elected in a timely manner by the participant. The amount deferred under this plan totaled $1.4 million and $0.7 million as of December 31, 2015 and 2014 , respectively. The Company owns life insurance policies which were purchased for former employees and directors covered by salary continuation agreements and director deferred compensation agreements. The cash surrender value of these policies totaled $56.0 million and $55.2 million at December 31, 2015 and 2014 . Cash value income (net of related insurance premium expense) related to these policies totaled $2.0 million , $1.6 million and $1.6 million during 2015 , 2014 and 2013 , respectively. The Company also has a non-contributory defined benefit pension plan which was assumed from Southern Community, covering substantially all employees of an acquired bank. Benefits under the plan are based on length of service and qualifying compensation during the final years of employment. Contributions to the plan are based upon the projected unit credit actuarial funding method to comply with the funding requirements of the Employee Retirement Income Security Act. The plan was frozen effective May 1, 2004. No contribution was required for the years ended December 31, 2015 , and 2014 . The unfunded status of the plan was $0.4 million at December 31, 2015 . The end of year plan assets and benefit obligation were $1.0 million and $1.4 million , respectively at December 31, 2015 .

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation As of December 31, 2015 , 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 years ended December 31, 2015 , 2014 and 2013 : (Dollars in thousands) Years Ended December 31, 2015 December 31, 2014 December 31, 2013 Stock options $ 288 $ 764 $ 571 Restricted stock 413 1,878 4,868 Total stock-based compensation expense $ 701 $ 2,642 $ 5,439 Salaries and employee benefits $ 701 $ 2,642 $ 5,439 Other expenses — — — Total stock-based compensation expense $ 701 $ 2,642 $ 5,439 The tax benefit related to stock-based compensation expense arising from restricted stock awards and non-qualified stock options was $0.3 million , $1.0 million and $2.1 million for the years ended December 31, 2015 , 2014 and 2013 , respectively. Stock Options Under the 2010 Plan and 2013 Plan, the exercise price for common stock options 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. No option may be exercised after the expiration of ten years from the date it is granted. No stock options were granted under these plans during the years ended December 31, 2015 or 2014. During the year ended December 31, 2013, 264,000 options were granted to employees at an exercise price of $18.00 vesting over average service periods of 2 years . The fair value of each option is estimated as of the date of the grant using the Black-Scholes Option Pricing Model. This model requires the input of subjective assumptions that will usually have a significant impact on the fair value estimate. The dividend yield assumption is consistent with management expectations of dividend distributions based upon the Company’s business plan at the date of grant. The risk-free interest rate was developed using the U.S. Treasury yield curve for a period equal to the expected life of the options on the grant date. The expected option life for the current period grants was estimated using the vesting period, the term of the option and estimates of future exercise behavior patterns. The volatility was estimated using a peer group assessment for periods approximating the expected option life. Appropriate weight is attributed to financial theory, according to which the volatility of an institution’s equity should be related to the volatility of its assets and the entity’s financial leverage. The following table summarizes the weighted average assumptions used to compute the grant-date fair value of options granted during the years ended December 31, 2013 and 2012 : Years Ended December 31, 2013 Dividend yield —% Risk-free interest rate 1.02% Expected option life 5.75 years Volatility 37% Weighted average grant-date fair value of options granted $6.52 ASC 718 requires the recognition of stock-based compensation for the number of awards that are ultimately expected to vest. During the years ended December 31, 2015 , 2014 and 2013 , 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 years ended December 31, 2015 , 2014 and 2013 is as follows: Years Ended December 31, 2015 December 31, 2014 December 31, 2013 (Shares in thousands) Shares Weighted Shares Weighted Shares Weighted Balance, January 1, 3,111 $ 20.26 3,124 $ 20.50 2,890 $ 21.39 Granted — — — — 264 18.00 Exercised (34 ) 18.00 — — — — Canceled, expired or forfeited (2 ) 351.04 (13 ) 80.99 (30 ) 83.28 Balance, December 31, 3,075 $ 20.12 3,111 $ 20.26 3,124 $ 20.50 At December 31, 2015 , the weighted average remaining contractual life for outstanding stock options was approximately 4.62 years and the aggregate intrinsic value was $37.1 million for stock options both outstanding and exercisable each. 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 December 31, 2015 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 $18.00 202 7.39 years $ 18.00 202 $ 18.00 $20.00 2,864 4.43 years 20.00 2,864 20.00 $28.44 - $2,026.00 9 2.62 years 104.61 9 104.61 $18.00 - $2,026.00 3,075 4.62 years $ 20.12 3,075 $ 20.12 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 terms of the restricted stock awards granted to employees prior to 2013 provided for vesting upon the achievement of stock price goals as follows: (1) one-third at $25.00 per share; (2) one-third at $28.00 per share; and (3) one-third at $32.00 per share. Achievement of stock price goals is generally defined as the average closing price of the shares for any consecutive 30 -day trading period exceeding the applicable price target. The value of the restricted stock was amortized on a straight-line basis over the implied service periods. No restricted stock awards were granted under the 2013 Plan prior to December 31, 2015 . On May 21, 2013, 4,000 restricted stock awards were granted under the 2010 Plan. The fair value of the restricted stock was estimated to be equal to the closing stock price on the grant date. On May 22, 2015, 405,129 restricted stock awards were vested upon achievement of the $28.00 stock price goal. The Company recognized $2.2 million in excess tax benefits related to the vesting of such awards. On November 6, 2015, 405,124 restricted stock awards were vested upon achievement of the $32.00 stock price goal. The Company recognized $3.2 million in excess tax benefits related to the vesting of such awards. The following table summarizes unvested restricted stock activity for the years ended December 31, 2015 , 2014 and 2013 : Years Ended December 31, 2015 December 31, 2014 December 31, 2013 (Shares in thousands) Shares Weighted Shares Weighted Shares Weighted Balance, January 1, 810 $ 13.89 1,215 $ 14.28 1,211 $ 14.27 Granted — — — — 4 18.00 Vested or released (426 ) 13.89 (405 ) 15.07 — — Canceled, expired or forfeited (384 ) — — — — — Balance, December 31, — $ — 810 $ 13.89 1,215 $ 14.28 Full Value Stock Awards During 2015 and 2014, 10,164 and 11,880 , respectively, shares of stock were granted to Directors under the 2013 Plan. The fair value of each stock award was estimated to be equal to the closing stock price on the date of the grant. The Company recognized the $0.3 million fair value of the stock awards in compensation expense on the grant date for each year.

Shareholders' Equity and Minimu

Shareholders' Equity and Minimum Regulatory Capital Requirements	12 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 December 31, 2015 and 2014 the Bank maintained capital ratios exceeding the requirement to be considered well capitalized. These minimum ratios along with the actual ratios and amounts for the Company and the Bank are presented in the following tables: (Dollars in thousands) Well Capitalized Adequately Capitalized 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% (Dollars in thousands) Well Capitalized Requirement Adequately Capitalized Requirement Actual December 31, 2014 Amount Ratio Amount Ratio Amount Ratio Tier 1 Capital (to Average Assets) CBF Consolidated N/A N/A $ 261,445 ≥ 4.0% $ 933,335 14.3% Bank $ 326,050 ≥ 5.0% $ 260,840 ≥ 4.0% $ 881,395 13.5% Tier 1 Capital (to Risk Weighted Assets) CBF Consolidated N/A N/A $ 207,370 ≥ 4.0% $ 933,335 18.0% Bank $ 310,245 ≥ 6.0% $ 206,830 ≥ 4.0% $ 881,395 17.0% Total Capital (to Risk Weighted Assets) CBF Consolidated N/A N/A $ 414,740 ≥ 8.0% $ 987,535 19.1% Bank $ 517,074 ≥ 10.0% $ 413,660 ≥ 8.0% $ 935,455 18.1% 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 December 31, 2015 and 2014 , 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. 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 establishes an integrated regulatory capital framework and introduces the “Standardized Approach” for risk weighted assets, which replaced 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 purpose 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 their capital level falls below the capital conservation buffer amount. These limitations establish a maximum percentage of eligible retained income that could be utilized for such actions. As of December 31, 2015, our capital conservation 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 requirement, which are designed to complement the capital conservation buffer, insured depository institutions are now required to meet the following increased capital level requirements in order to qualify as "well capitalized":" (i) a new common 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 The Company's board of directors approved a quarterly common dividend program commencing with a cash dividend of $0.10 per share declared and paid during the fourth quarter of 2015. Subsequent to year end, the Company declared a cash dividend of $0.10 per share on January 28, 2016, paid on February 22, 2016, to shareholders of record as of February 8, 2016. Share Repurchases Through 2015, the Company’s Board of Directors authorized stock repurchase plans of up to $300.0 million . In January 2016, the board of directors authorized a new $100.0 million repurchase program. Stock repurchases may be made from time to time, on the open market or in privately negotiated transactions. The approved stock repurchase programs do not obligate the Company to repurchase any particular amount of shares, and the programs may be extended, modified, suspended, or discontinued at any time.

In assessing the need for a valuation allowance, management considered the following positive factors: 1. projections of future operating results which forecast that the Company will continue to recognize pre-tax income on a consolidated basis; 2. reductions in operating expenses have been achieved as evidenced by continued progress in reducing operating costs and legacy credit expenses; and 3. the Company expects interest rates to rise in the future, which should have a favorable impact on our net interest income trend and overall return on assets. A negative factor that management considered was the severe losses incurred by the acquired institutions as a result of the severe recession and significant decline in real estate values in their local markets. In addition, Section 382 of the Internal Revenue Code limits the ability of the Company to utilize net operating losses and deduct built in losses for income tax purposes. The Company appropriately considers these limitations and has taken them into account in calculating the net deferred tax assets. These factors represent the most significant positive and negative evidence that management considered in concluding that no valuation allowance was necessary at December 31, 2015 and 2014 . The Company and its subsidiaries are subject to U.S. federal income tax, as well as income tax of the states of Florida, New York, South and North Carolina and Tennessee. During 2013, changes in certain statutory rates were enacted into law, which reduced the Company's expected state income tax rate. As a result, the Company recorded a $1.5 million charge to income tax expense. At December 31, 2015 and 2014 the company had $107.7 million and $91.1 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 December 31, 2015 and 2014 the company had $100.1 million of gross state net operating loss carryforwards. At December 31, 2015 and 2014 , the Company had no material unrecognized tax benefits and no material amounts recorded for uncertain tax positions.

Commitments and Contingencies Disclosure [Abstract]
Loan Commitments and Other Related Activity	Loan Commitments and Other Related Activity Some financial instruments, such as loan commitments, credit lines, letters of credit and overdraft protection, are issued to meet customer financing needs. These are agreements to provide credit or to support the credit of others, as long as conditions established in the contract are met, and usually have expiration dates. Commitments may expire without being used. Off-balance sheet risk of credit losses exists up to the face amount of these instruments, although material losses are not anticipated. The same credit policies are used to make such commitments as are used for loans, including obtaining collateral upon exercise of the commitment. The contractual amount of financial instruments with off-balance-sheet risk at December 31, 2015 is as follows : (Dollars in thousands) Fixed Rate Variable Rate Total Commitments to make loans $ 14,483 $ 20,704 $ 35,187 Unfunded commitments under lines of credit 273,467 873,368 1,146,835 Total $ 287,950 $ 894,072 $ 1,182,022 Commitments to make loans are made for periods ranging from 30 days to 90 days . As of December 31, 2015 , the fixed rate loan commitments have interest rates ranging from 3.3% to 8.0% , and specific loan maturities ranging from 1 year to 10 years . As of December 31, 2015 the Bank was subject to performance letters of credit totaling $29.9 million and financial letters of credit totaling $36.7 million .

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 December 31, 2015 , Capital 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. We consider 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 December 31, 2015 , 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.

(2) Includes Federal Reserve Bank, Federal Home Loan Bank and Bankers Bank stocks. 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 Reserve, Federal Home Loan Bank stock, FDIC indemnification asset and correspondent banks’ stocks 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. The methods used to estimate fair value of loans do not necessarily represent an exit price. Fair values for impaired loans are estimated using discounted cash flow analysis or underlying collateral values. 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 Instruments and Hedging Activities	Derivative Instruments 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 $2.0 million will be reclassified as an increase to interest income from amounts reported in accumulated comprehensive income. During the year ended December 31, 2015 , 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. 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 year ended December 31, 2015 , the Company recorded $36 thousand in non-interest income and $25 thousand in non-interest expense as a result of changes in fair value of derivatives. For the year ended December 31, 2014, the company recorded $1.7 million in non-interest income and $118 thousand in non-interest expense as a result of changes in fair value of forward loan sales contracts. 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) December 31, 2015 December 31, 2014 Number of instruments Balance Sheet Location Fair Value Notional Fair Value Notional Assets derivatives Derivatives designated as hedging instruments Interest rate swaps 3 Other assets $ 893 $ 165,000 $ — $ — Derivatives not designated as hedging instruments Forward loan sales contracts 36 Other assets 40 6,967 4 1,640 Total assets derivatives $ 933 $ 171,967 $ 4 $ 1,640 Liabilities derivatives Derivatives designated as hedging instruments Interest rate swaps 1 Other liabilities $ 108 $ 70,000 $ — $ — Derivatives not designated as hedging instruments Forward loan sales contracts 2 Other liabilities 2 1,213 26 7,578 Total liability derivatives $ 110 $ 71,213 $ 26 $ 7,578 The table below presents the effect of the Company's derivative financial instruments on the Consolidated Statements of Income for the year ended December 31, 2015 : (Dollars in thousands) Year Ended December 31, 2015 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 swaps $ 2,915 Interest income $ 2,129 N/A $ — The table below presents a gross presentation, the effects of offsetting, and a net presentation of the Company's derivatives as of December 31, 2015 : 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 swaps $ 893 $ — $ 893 $ — $ 780 $ 113 Total $ 893 $ — $ 893 $ — $ 780 $ 113 Offsetting of derivative liabilities: Interest rate swaps $ 108 $ — $ 108 $ — $ — $ 108 Total $ 108 $ — $ 108 $ — $ — $ 108 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 December 31, 2015 , there was one derivative in a $108 thousand 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 Company and its 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 (the “Bank”; formerly known as Capital Bank, N.A.). 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 152 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 consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). All significant inter-company accounts and transactions have been eliminated in consolidation. The following is a summary of the more significant accounting policies. Certain prior period amounts have been reclassified to conform to the current period presentation.
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.
Cash and Cash Equivalents	Cash and cash equivalents include cash on hand and highly-liquid items with an original maturity of three months or less including amounts due from banks, federal funds sold, and interest-bearing deposits at the Federal Home Loan Bank (“FHLB”) and the Federal Reserve Bank of Atlanta (“FRB”). Accordingly, the carrying amount of such instruments is considered to be a reasonable estimate of fair value.
Trading Securities	Marketable equity securities are recorded on a trade-date basis and are accounted for based on the securities’ quoted market prices from a national securities exchange. Those purchased with the intention of recognizing short-term profits are classified as and included in trading securities on our balance sheet. Both realized and unrealized gains and losses on trading securities are included in noninterest income.
Investment Securities and Other than Temporary Impairment	Investment securities which may be sold prior to maturity are classified as available-for-sale and are carried at fair value, with unrealized gains and losses reported in other comprehensive income. Other securities such as Federal Home Loan Bank stock are carried at cost, periodically evaluated for impairment and are included in other assets on the balance sheets. Investment securities where the Company has both the intent and ability to hold to maturity are classified as held-to-maturity and reported at amortized cost. Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are amortized using the level-yield method without anticipating prepayments, except for mortgage backed securities where prepayments are anticipated. Gains and losses on sales are realized on the trade date and determined using the specific identification method based on the amortized cost of the security sold. Management regularly reviews each investment security for impairment based on criteria that include the extent to which cost exceeds fair value, the financial health of and specific prospects for the issuer(s) and our ability and intention with regard to holding the security. Management evaluates securities for other-than-temporary impairment (“OTTI”) at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. In determining OTTI under accounting guidance, management considers many factors, including but not limited to: (1) the financial condition and near-term prospects of the issuer, (2) whether the market decline was affected by macroeconomic conditions, and (3) whether the entity has the intent to sell the debt security or more likely than not will be required to sell the debt security before its anticipated recovery. The assessment of whether an OTTI exists involves a high degree of subjectivity and judgment and is based on the information available to management at a point in time. When OTTI is determined to have occurred, the amount of the impairment recognized in earnings depends on whether management intends to sell the security or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis, less any current-period credit loss. If management intends to sell or it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis, less any current-period credit loss, the impairment is required to be recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its fair value at the balance sheet date. If management does not intend to sell the security and it is not more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss, the credit worthiness of the issuer is analyzed to determine if there is a credit component of the unrealized loss that would require recognition in earnings. Impairment identified through this analysis is separated into the amount representing the credit loss and the amount related to all other factors (i.e., changes in market interest rates, liquidity premiums, etc.). The amount of impairment related to the credit loss is determined based on the present value of cash flows expected to be collected and is recognized in earnings. The amount of the impairment related to other factors is recognized in other comprehensive income, net of applicable taxes. The previous amortized cost basis less the OTTI recognized in earnings becomes the new amortized cost basis of the investment. Future declines in the fair value of securities may result in impairment charges which may be material to the financial condition and results of operations of the Company.
Loans Held for Sale	Certain residential fixed rate mortgage loans originated by the Company are sold to third parties on a servicing released basis. Certain of these sales are subject to temporary recourse provisions. The recourse provisions may require the repurchase of the outstanding balance of loans which default within a limited period of time subsequent to the sale. The recourse periods vary by investor and extend up to seven months subsequent to the sale of the loan. All origination fees are recognized as income at the time of the sale. Mortgage loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or market, as determined by outstanding commitments from investors. Net unrealized losses, if any, are recorded as a valuation allowance and charged to earnings.
Purchased Credit-Impaired Loans	When it is probable that the Company will not collect all contractual cash flows associated with acquired loans, unless specifically exempt, these acquired loans are accounted for under accounting guidance for purchased credit-impaired (“PCI”) loans. Any Allowance for Loan and Lease Losses (“the Allowance”) previously associated with these loans does not carry over to the Company and is eliminated in the purchase accounting adjustments. The fair value of the PCI loans is then assigned based on the present value of estimated future cash flows including prepayments but exclusive of any loss-sharing arrangements. The excess of the gross cash flows expected to be collected over the present value of cash flows at the acquisition date (i.e., the accretable yield) is accreted into income over the estimated remaining term of the PCI loans using the effective yield method, provided that the timing and amount of future cash flows is reasonably estimable. Accordingly, such loans are not classified as nonaccrual as the accretable yield is reported as interest income. The impact of changes in variable interest rates is recognized prospectively as adjustments to the accretable yield. For further discussion of the Company’s acquisitions and loan accounting, see Note 3. Business Combinations and Acquisitions and Note 5. Loans, respectively.
New Loans and Acquired Non-PCI Loans	New loans that management has the intent and ability to hold are reported at the principal balance outstanding, net of deferred loan fees and costs, and an allowance for loan and lease losses. Acquired non-PCI loans are initially reported at their acquisition date fair value. Subsequently, acquired non-PCI loans are reported net of amortization or accretion of any applicable acquisition discount or premium and an allowance for loan and lease losses. Interest income on New and non-PCI acquired loans is reported on the interest method and includes amortization of net deferred loan fees, costs and any applicable acquisition discount or premium over the loan term. Amortization of deferred loan fees and costs is based on the contractual lives of the loans and does not include anticipation of prepayments. If the collectability of interest appears doubtful, the loan is classified as nonaccrual.
Nonaccrual Loans	The majority of loans are placed on nonaccrual status when it is probable that principal or interest is not fully collectible, or generally when principal or interest becomes 90 days past due, whichever occurs first. Certain loans past due 90 days or more may remain on accrual status if management determines that it does not have concern over the collectability of principal and interest and such loans are in the process of collection. Generally, when loans are placed on nonaccrual status, accrued and unpaid interest receivable is reversed against interest income in the current period. Interest payments received thereafter are generally applied as a reduction to the remaining principal balance as long as concern exists as to the ultimate collection of the principal. Loans are generally removed from nonaccrual status when they become current as to both principal and interest and concern no longer exists as to the collectability of principal and interest. The Company’s policies related to when loans are placed on nonaccrual status conform to guidelines prescribed by bank regulatory authorities.
Direct Financing Leases	Direct financing leases are carried at the aggregate of lease payments receivable and estimated residual value of the leased property, if applicable, less unearned income. Interest income on direct financing leases is recognized over the term of the leases to achieve a constant periodic rate of return on the outstanding investment. Initial direct costs are deferred and amortized over the lease term as a reduction to interest income using the effective interest method.
Allowance for Loan and Lease Losses	The Company maintains an allowance for loan and lease losses to absorb losses incurred in the loan portfolio. The allowance is based on ongoing, quarterly assessments of the probable estimated incurred losses inherent in the portfolio of loans held for investment. The allowance is increased by the provision for loan and lease losses, which is charged against current period operating results and decreased by the amount of charge offs, net of recoveries. The Company’s methodology for assessing the appropriateness of the allowance consists of several key elements, which include the formulaic allowance and the specific allowance for impaired loans. Management develops and documents its systematic methodology for determining the allowance for loan and lease losses by first dividing its portfolio into segments-commercial real estate, commercial, consumer and other. The Company further divides the portfolio segments into classes and subclasses based on initial measurement attributes, risk characteristics or its method of monitoring and assessing credit risk (such as owner occupied commercial real estate, for which the Company believes risk characteristics and cash flows are aligned with the Commercial class). The classes and subclasses for the Company are as follows: Commercial real estate • Non-owner occupied commercial real estate • Other commercial construction and land • Multifamily commercial real estate • 1-4 family residential construction and land Commercial • Owner occupied commercial real estate • Commercial and industrial • Lease Financing Consumer • 1-4 family residential • HELOC • Junior lien • Other consumer loans • Indirect auto Other • Farmland • Agriculture • All other loans For non-PCI loans, the allowance for loan and lease losses is calculated by applying loss factors to outstanding loans. It is the Company’s policy to use loss factors based on historical loss experience which may be adjusted for significant factors that, in management’s judgment, affect the collectability of the portfolio as of the evaluation date. The Company has limited historical loss experience on newly originated loans and the historical loss information available relating to the portfolios of acquired loans is considered by management to be irrelevant to newly originated loans due to differences in underwriting criteria and loan type. Accordingly, the Company currently is utilizing loss rates from a peer group of comparable banks based on size, portfolio type and geography as the basis for determining loss factors to apply to any outstanding loans. The Company derives the loss factors for all segments from pooled loan loss factors. Such pooled loan loss factors are based on peer group historical net charges. Loan loss factors, which are used in determining the allowance, are adjusted quarterly primarily based upon the changes in the level of historical net charge offs and parameter updates by management. Management estimates probable incurred losses in the portfolio based on a historical loss look-back period. The look-back period is representative of management’s consideration of relevant historical loss experience. Furthermore, based on management’s judgment, the Company’s methodology permits adjustments to any loss factor used in the computation of the allowance for significant factors, which affect the collectability of the portfolio as of the evaluation date, but are not reflected in the loss factors. By assessing the probable estimated incurred losses in the loan portfolio on a quarterly basis, management is able to adjust specific and inherent loss estimates based upon the most recent information that has become available. This includes changing the number of periods that are included in the calculation of the loss factors and adjusting qualitative factors to be representative of the current economic cycle and other factors impacting the portfolio. Generally, for Commercial loans, the Company evaluates individual nonaccrual loans with recorded investment balances greater than or equal to $0.5 million and substandard but accruing loans with recorded investment balances greater than or equal to $1.0 million for impairment. Residential mortgage and consumer loans are generally not individually evaluated for impairment unless they become non-accrual and exceed $0.5 million in recorded investment or represent troubled debt restructuring. Loans are considered impaired when the individual evaluation of current information regarding the borrower’s financial condition, loan collateral, and cash flows indicates that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement, including interest payments. Impaired loans are carried at the lower of the recorded investment in the loan, the present value of expected future cash flows discounted at the loan’s effective rate, the loan’s observable market price, or the fair value of the collateral, if the loan is collateral dependent. Excluded from the impairment analysis are large groups of smaller balance homogeneous loans such as consumer, home equity line, indirect auto and residential mortgage loans, which are evaluated on a pool basis. Loans are charged off in whole or in part when they are considered to be uncollectible. For commercial and agricultural, construction and vacant land and commercial mortgage loans, such evaluations are generally considered for collectability based on borrower financial condition as well as the value of any collateral. For residential mortgage and consumer loans, this evaluation is generally based on past due status as discussed above, as well as an evaluation of borrower creditworthiness and the value of any collateral. Recoveries of amounts previously charged off are recorded as an increase in the allowance for loan and lease losses. Significant risk characteristics considered in estimating the allowance for credit losses include the following: • Commercial and agricultural-industry specific economic trends and individual borrower financial condition; • Construction and vacant land, farmland and commercial mortgage loans-type of property (i.e., residential, commercial, industrial) and geographic concentrations and risks and individual borrower financial condition; and • Residential mortgage, indirect auto and consumer-historical charge-offs and current trends in borrower’s credit, property collateral, and loan characteristics. The allowance for loan and lease losses associated with PCI loans is comprised of an allowance necessary for certain pools of loans. An allowance related to a PCI loan pool is established when the present value of expected cash flows from the loan pool is less than its recorded investment. The amount of the allowance is equal to the difference between these amounts. In calculating the present value of expected cash flows for this purpose, changes in cash flow estimates pursuant to credit factors are isolated from those related to changes in interest rate indices. Any subsequent improvement in the expected cash flows related to the loan pool results in a reduction of any previously established allowance. Any changes in the allowance, including the initial establishment, are recorded in earnings for the current period as a component of the provision for loan losses. Estimates of expected cash flows incorporate assumptions of expected prepayments, probability of default and loss severity given default. Probability of default assumptions are derived from incurred and expected loss data published in third party research reports for commercial, commercial real estate and residential loans. Probability of default assumptions for residential loans are adjusted to incorporate increased risk for historical delinquency occurrence and high loan to collateral value (“LTV”) ratios, and updated borrower credit information. For commercial and commercial real estate loans, probability of default assumptions are based upon loan risk ratings of the Company. Loss severity given default assumptions are developed based upon third party research reports or estimates of current LTV ratios which use real estate price index values for the applicable state or Metropolitan Statistical Area (“MSA”) where available.
Foreclosed Assets	Assets acquired through, or in lieu of, loan foreclosure or repossession are generally held for sale and are initially recorded at fair value less cost to sell when acquired, establishing a new cost basis. If fair value subsequently declines below the initial recorded value, a valuation allowance is recorded through expense so that the asset is reported at the lower of cost or fair value less cost to sell. If fair value subsequently increases, a reduction of any previous valuation allowance is recorded, which is limited to the total amount of the valuation allowance. Costs incurred after acquisition are generally expensed.
FDIC Indemnification Asset	Pursuant to purchase and assumption agreements with the FDIC, the Bank has entered into loss share agreements in which 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 during the term of the agreement. An indemnification asset is recorded at fair value at the acquisition date. The indemnification asset is recognized at the same time as the indemnified loans, and measured on the same basis, subject to collectability or contractual limitations. The indemnification asset on the acquisition date reflects the present value of future cash flows expected to be received from the FDIC using an appropriate discount rate which reflects counterparty credit risk. Subsequent to initial recognition, the indemnification asset continues to be measured on the same basis as the related indemnified loans and other real estate owned "OREO" and is impacted by changes in estimated cash flows associated with these loans and foreclosed properties. Deterioration in expected cash flows of the loans are immediately recorded as an adjustment to the allowance for loan and lease losses and would correspondingly result in an increase in the indemnification asset, with the offset recorded through the consolidated statement of income. Improvements in the cash flows of the loans would first result in a reversal of any existing cumulative impairment and related valuation allowance and a corresponding decrease in the indemnification asset. Subsequent to the full reversal of any such valuation allowance, additional improvement in loan cash flows is reflected as an adjustment to yield that is accreted into income over the remaining term of the loans along with increased amortization of the indemnification asset. Such amortization is recognized over the shorter of a) the remaining term of the loans or b) the life of the shared loss agreements. Loss assumptions used for the basis of the indemnified loans are consistent with the loss assumptions used to measure the indemnification asset. Fair value accounting incorporates into the fair value of the indemnification asset an element of the time value of money, which is accreted back into income over the life of the loss sharing agreements. Upon the determination of an incurred loss, the indemnification asset will be reduced by the amount owed by the FDIC. A corresponding claim receivable is recorded until cash is received from the FDIC.
Premises and Equipment	Land is carried on the balance sheet at its cost. Premises and equipment are reported at cost less accumulated depreciation. For financial reporting purposes, premises and equipment are depreciated using the straight-line method over their estimated useful lives. Expenditures for maintenance and repairs are charged to operations as incurred, while major renewals and betterments are capitalized. For Federal income tax reporting purposes, depreciation is computed using primarily accelerated methods.
Goodwill and Other Intangible Assets	Goodwill and other intangible assets (including core deposit base premiums, customer relationship intangibles, and mortgage servicing rights) arising from business purchase combinations are initially recorded at fair value. Goodwill and other intangible assets with indefinite useful lives are not amortized and are tested for impairment at least annually as of the first day of our third quarter, or whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Other intangible assets with finite useful lives are amortized over their estimated useful lives to their estimated residual values and tested for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Other intangible assets are considered to be impaired if the undiscounted cash flows from its associated asset group are less than their recorded net book value; if impairment is determined to exist, the asset must be written down to its fair value based upon discounted cash flows in the period in which impairment is determined to exist. Factors considered in the impairment evaluation include but are not limited to fair market value, general market conditions and projections of future operating results. In addition, after evaluating the Company’s structure and components, it has been determined that the Company consists of one reporting unit.
Company Owned Life Insurance	The Company owns life insurance policies on certain current and former directors and employees of its subsidiaries. These policies are recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement, if applicable.
Derivative Instruments and Hedging Activities	The Bank manages its interest rate risk position through the use of interest rate derivatives (also referred to as hedging instruments, hedging transactions, or hedges). It is the responsibility of the Board of Directors and our asset liability committee to establish an effective policy for the purpose of using derivatives consistent with the Bank’s underlying interest rate risk strategy, business objectives, level of risk tolerance (such as interest rate risk sensitivity policy limits), and financial capacity. Adherence to these requirements ensure that the Bank performs the proper due diligence prior to obtaining, designating and documenting the hedging instruments and the Bank is in compliance with all applicable laws and regulations and accounting principles generally accepted in the United States. 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.
Fair Value of Financial Instruments	Fair values of financial instruments are estimated using relevant market information and other assumptions. Fair value estimates include uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect these estimates.
Operating Leases	Rent expense for the Company’s operating leases is recorded on a straight-line basis over the initial lease term and those renewal periods that are reasonably assured. It is common for lease agreements to contain various provisions for items such as step rent or other escalation clauses and lease concessions, which may offer a period of no rent payment. These types of transactions are recorded into expense on a straight line basis over the minimum lease terms. Certain leases require the Company to pay property taxes, insurance and routine maintenance.
Income Taxes	The provision for income taxes is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities between periods. Deferred tax assets and liabilities are measured using the balance sheet method. Under this method, deferred tax assets and liabilities are determined based on differences between the carrying amount of balance sheet items and their corresponding tax values. Changes in the deferred tax assets and liabilities represent decreases and increases in the future tax liability due to changes in temporary differences and utilization of net operating loss carryforwards and tax credit carryforwards. Current recognition is given to changes in tax rates and laws. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of benefit that is greater than 50% likely to be realized upon settlement. For tax positions not meeting the “more likely than not” test, no benefit is recorded. If applicable, accrual of penalties and interest related to an unrecognized tax benefit are recorded in income tax expense. 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. As of December 31, 2015 and 2014, management considered the need for a valuation allowance and based upon its assessment of the evidence available at the time of the analysis, concluded that a valuation allowance was not necessary. In addition, management’s assessment of the need for a valuation allowance includes interpretations of tax laws, lapse of statute of limitations and changes in statutory and regulatory guidance. The Company is no longer subject to federal, state and local examinations by tax authorities for years before 2011.
Loan Commitments and Related Financial Instruments	Loan Commitments and Related Financial instruments include off-balance sheet credit instruments such as commitments to make loans and letters of credit issued to meet customer financing needs. The face amount for these items represents the exposure to loss before considering customer collateral or ability to repay. Such financial instruments are recorded on the balance sheet when they are funded.
Securities Purchased Under Agreements to Resell and Securities Sold Under Agreements to Repurchase	Securities purchased under agreements to resell and securities sold under agreements to repurchase are accounted for as collateralized lending and borrowing transactions, respectively, and are recorded at the amounts at which the securities were acquired or sold plus accrued interest. The fair value of collateral either received from or provided to a third party to secure these transactions is regularly monitored and additional collateral is obtained, provided or requested to be returned as appropriate.
Loss Contingencies, Contingent Value Rights and Loss Share Clawback Liabilities	Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Current contingent value rights and FDIC loss share related clawback liabilities are recorded within accrued expenses and other liabilities and periodically remeasured, with any changes in measurement accounted for as non-interest expense.
Related Party Transactions	Certain of the directors and executive officers of Capital Bank Corporation, members of their immediate families and entities with which they are associated are deposit and loan customers of the Bank.
Operating Segments	While the chief operating decision-makers monitor the revenue streams of the various products and services, the financial services operations are considered by management to be one reportable segment. Operations are managed and financial performance is evaluated on a Company-wide basis.
Recent Accounting Pronouncements	In January 2016, the Financial Accounting Standard Board (the “FASB”) issued Accounting Standards Update ("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)”. 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 is not expected to 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”. 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 is not expected to 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 is not expected to 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.
